A rotary die cutter for die-cutting blanks one after another has a blank feed unit, a pair of cylinders for die-cutting the blanks, and an endless member running synchronized with the cylinders. The blanks are gripped by grippers mounted at equal spacings on the endless member. The cylinders are adapted to allow the grippers to pass between the cylinders while gripping the blanks.

Device to apply paraffin oil or like onto the surface of textile threads, so as to make them smoother and facilitate weaving thereof. The device comprises: at least one container or vessel (1) for a paraffin oil, closed by a cover (5); at least one rove or felt strip (9) having at least one vertical length with the lower end plunged into the oil of the container (1) and one length, usually horizon...

A fire alarm system which makes fire determination based on a novel idea which considers various changes of the physical phenomena in the surroundings caused in relation with the occurrence of a fire in terms of changes of vectors. These changes in the physical phenomena are detected by the detecting section in the form of analog data and processed by a data sampling section as sampled data and st...

A centrifugal separator comprising a circular centrifuge separation channel having an inlet for receiving a liquid to be separated and an outlet for providing components of the liquid in separated layers at different radial locations, a collection chamber for receiving the separated layers, the chamber having first, second and third outlets in the collection chamber for removing components at diff...

(A) In a new process for separating the mixture of the enantiomeric forms of 1-(4-amino-3,5-dichlorophenyl) -2-(tert-butyl)-hydroxy-amino-ethanol (I) the mixture is treated with a ca equimolar amount of (-)-diacetone-2-keto-l-gulonic acid (II) in alkanol and the resulting poorly soluble salt of one of the enantiomsis is separated off. (B) The enantiomers of (I) having specific rotations in chloro...

The bearing sleeve (38) is connected to a transport element (11) serving for transporting the spindle (24) together with the attached cop (6) to and from a winding machine. The constructional unit of the transport element (11) and spindle (24) can have a switchable spindle brake (32) or a switchable coupling device (29 to 36) for a loose wharve (28) serving as a drive element.

A method and apparatus for increasing the winding speed of an automatic winding machine includes successively supplying unwinding stations of the automatic winding machine with spindles each having one spindle bearing and one cop with a cop tube having a given winding direction and being ready for unwinding. The spindles are rotated opposite the given winding direction of the cops while unwinding ...

Adaptation of the weight compensation is to be made possible in a simple manner for various loads to be received by the stand. In order to achieve this, the stand exhibits an openable compartment (4) for receiving weights (15). Stands of this type are used, in particular, in medical engineering.

1. Rendering distributor or collector for the distribution or collection of a fluid medium at a consumer point, the medium flowing through flexible lines (9, 10) laid in conduits (11, 12) and either passed via a fitting (A), arranged inside a connection box (8) and having two pipe connections, to a further consumer point or fed to the first-mentioned consumer point by means of two lines and is col...

In an exemplary embodiment, two radiation detectors are arranged behind the radiography subject. One of the detectors is covered by a radiation filter. A different radiation attenuation along the radiation paths of the respective detectors thereby takes place, so that, through division of the output signals of the detectors, a quotient signal can be obtained which corresponds to the radiation tran...

A method of producing a heat-shrinkable elastomer comprising the steps of: (a) without the application of external heat, extending an elastomer comprising a copolymer of alternating polyamide and polyether repeat block polymer segments to an extension beyond that at which permanent deformation occurs thereby to orient said elastomer uniaxially, and (b) subsequently releasing the tension on said el...

In the case of a filtering separator, the housing of which is divided by a perforated partition into a filter space and a pure gas space the filter space being supplied with unrefined gas, receiving filter elements which are to be cleansed by counterflow flushing and/or agitation, and having a bottom dust collector trough incorporating a dust extraction conveyor, the dust obtained being partly fed...

An offshore platform consists of a superstructure 1 supported on columns 2 embedded in a foundation unit on the sea floor. The superstructure 1 is supported in a lowered position on the foundation unit during construction and sea transport. The foundation kit consists of an upper section 4 and a lower section 5. The lower section 5 provides sufficient buoyancy for flotation of the entire platform ...

A bedding underlayer for the bed of an incontinent patient comprises an impervious base layer 2, 3 substantially wider than the bed so that opposite lateral portions 2 of the base layer can be tucked under the mattress of the bed, and a liquid-absorbing layer 4 in the middle of the base layer and of the same width as the bed, or of lesser width. The liquid- absorbing layer 4 is surrounded, at its ...

The device 10 is intended to measure the glucose level in a blood sample, by measuring the change in colour of a sensitised strip 11 on which a sample has been applied, the device 10 having a housing 12, and an input station 13 for receiving the sensitised strip 11 with a sample portion 14 on which a sample is applied. A light source (17, Fig 2, not shown) is arranged in the housing 12 to direct a...

Flexible polyurethane foam having reduced tendency to form burning embers and which produces a char when it is ignited and burned is provided by incorporating into the reaction mixture before foaming an aldehyde or an aldehyde generator. In a preferred embodiment, flexible polyurethane foam of increased flame retardance is provided by also incorporating a flame retardant into the reaction mixture ...

In the case of a filtering separator, the housing of which is divided by a perforated partition into a filter space and a pure gas space the filter space being supplied with unrefined gas, receiving filter elements which are to be cleansed by counterflow flushing and/or agitation, and having a bottom dust collector trough incorporating a dust extraction conveyor, the dust obtained being partly fed...

A gasoline composition contains a minor amount of at least one of a specified group of quaternary ammonium hydroxides for decreasing or reversing the octane requirement increase (ORI) for a fuel-fired spark ignition internal combustion engine. Tetrabutylammonium hydroxide and tricaprylicmethylammonium hydroxide are two preferred compounds for use.
