Method of and apparatus for splicing fibrous formations, particularly yarns. Mutually closely arranged parallel and overlapping ends of the fibrous formations to be spliced are disposed inside the pressure channel of a splicing chamber. The thus disposed fibrous formations are subjected to the whirling action of pressure air and at least at one of the mouth of said pressure channel they are subjec...

Method of and apparatus for preparing and splicing the ends of fibrous formations, particularly in the pressure channel of a pneumatic splicing chamber provided with a displaceable lid. Excess lengths of ends of fibrous formations to be spliced are placed within the pressure channel in overlapping substantially parallel relationship and are then cut to a desired length by cutting means such as sci...

Prior to the actual splicing process, a preparation process is carried out in a preparation apparatus. The apparatus comprises a preparation tube having one or more circumferentially arranged air jet nozzles. The axis of each nozzle is inclined to the axis of the preparation tube and has a mouthpiece at the inlet end. The yarn end to be prepared is introduced into the preparation tube, where it is...

The invention concerns an X-ray diagnostic apparatus with a motor-driven, vertically adjustable compression carriage, a means of support for a compression plate, and with a support plate for the object photographed. A means of support for a second closer to the focus, support plate and two support locations for the compression plate are provided, of which one is associated with the support plate w...

A method of increasing the abrasion resistance of glass articles is disclosed. It has been found that by providing a vitreous substrate with a micro-roughened surface and an overlayer of dry lubricious organic coating, substantially increased lubricity and abrasion resistance is obtained. When the micro-roughened surface is provided by bonding a discontinuous distribution of discrete particulate m...

The invention provides an apparatus for removing an animal from a shell. The apparatus has a tubular helical main portion having an inlet, an outlet and an attachment portion for coupling the apparatus to a source of high pressure fluid. The apparatus may be inserted into the shell and coupled to high pressure fluid which urges the animal from the shell.

A novel crystallographic modification ( beta -modification) of the pigment C. I. Pigment Red 53:1 is described and claimed which has characteristic reflection values in its X-ray diffraction pattern obtained by means of Cu-K alpha radiation. This novel pigment form is obtained by reacting an aqueous solution of an alkali metal or ammonium salt of the formula 1 (1) with the equivalent...

A pleat self-spacing mechanism and a method for creating the mechanism which includes the scoring of a continuous line pattern upon the portion of the filter media which forms the pleat tip (22, 23). When the scored filter media is folded the pattern creates a structurally integral element within the pleated media such that a predetermined spatial relationship between adjacent pleats is maintained...

PURPOSE:To make troubleshooting of the state of a failure and a failed part easy, by inputting respectively each output of a parallel redundant circuit to a separate exclusive OR circuit together with a reference signal for obtaining the OR of the output. CONSTITUTION:A signal 1 passes through redundant circuits 2-4 and outputs 2a-4a are inputted to a 2-out-of-3 circuit 5. Further, the outputs 2a-...

An electrical surgical knife device stops supplying an incision current, a coagulation current or a blend current whenever at least two of selection switches are actuated at the same time, said selection switches being provided for selecting the incision current, the coagulation current and the blend current, respectively.

Flashlamps (13 to 17, n), which can be sequentially controlled by a multiplexer (52), are arranged above and/or alongside the track of travel of models (39), to balance a signal evaluation circuit (62), and of test pieces (3), to carry out testing, and put in groups (18, 19, 20) onto different test zones of the continuously moving glass objects. Flashlight reflected from the glass objects is proje...

There is disclosed a needle assembly comprising a needle, a needle-retaining portion, a removable needle protector portion, and a resilient member for removing liquid from the surface of the needle which is disposed around the needle rearward of its point. The liquid removing member has a needle-accommodating opening with a diameter approximately that of the outside diameter of the needle. The mem...

The invention relates to a process for the production of metallic powders with the aid of a rotating electrode and an electric arc. By choosing hydrogen as the gas, pores filled with noble gas are avoided. An expedient apparatus for carrying out the process is described.

The invention relates to a process for the manufacture of highly resilient, cold-curing polyurethane foams with the distinctive feature that polysiloxane-polyoxyalkylene block copolymers with the following characteristics are used as foam stabilizers: (a) the polysiloxane block is linear or branched and contains an average of 4 to 25 silicon atoms, wherein the organic radicals linked to the silico...

A centrifugal vapor compressor having a two-position, pressure controlled diffuser throttle ring is disclosed. The throttle ring is positively maintained in a minimum or a maximum throttling position by supplying either a relatively low pressure or a relatively high pressure, respectively, to a cavity behind the throttle ring. The throttle ring may be one of any of a variety or types of throttle r...

A fluidized bed furnace for consuming a liquid fuel in which there is a fluidization zone of increasing cross-sectional area adjacent to and downstream of the liquid fuel injection nozzles. This arrangement allows better dispersion of the oil and bed material giving more efficient combustion.

An exchangeable or removable nozzle arrangement for use in a fluidized bed furnace is movable and in sealing contact with a surrounding sleeve at one end of the nozzle and may be withdrawn from the sleeve through a valve at the other end of the sleeve. An inlet to the space between the sleeve and the nozzle is connected to a source of pressurized fluidizing gas. Upon removal of a nozzle, while the...
