The cap also includes a fluid passage to which a length of tubing can be integrally connected to transfer fluid into the container. The transfer tubing can be sealed and severed close to the cap. The cap includes a pocket which receives the remaining sealed end portion of ...

A flashlight holder includes a single strap having two sets of spaced openings which are provided at opposite ends of the strap. The strap can be separated into a pair of similar straps. The strap is formed of a resilient rubber-like material. The openings are defined by elongated slots or circular openings in the strap. The first opening of each set is constructed and arranged for connection to a...

Spray combination of two liquids is advantageously accomplished by applying a high potential of one polarity to a first liquid thereby converting the first liquid into finely divided ionized particles, spraying a second liquid through a porous member and applying thereto a high potential of the other polarity thereby converting the second liquid into finely divided ionized particles, and combining...

A heel holder includes a sole holder which is supported for pivotal movement about a horizontal axis on a support member and has a control surface. A locking lever pivotally supported on the support member has a nose engageable with the sole holder control surface. A spring housing having a release spring therein is pivotal about the sole holder pivot axis, and a slide member movably supported in ...

A checking system for checking defects on an optically flat surface of an object to be checked is adapted to spirally scan the surface of the object with a laser beam which is projected from an optical head. The laser beam is reflected from the surface of the object and converted by a photodetector to an electric signal. The level of the electric signal is compared with a reference level to produc...

A tire building drum is described as having, a plurality of radially movable bead lock segments at each end of the drum for holding the tire bead rings during the turn-up operation, a pair of turn-up bladders, and a pair of carriers which work in conjunction with the bead lock segments and turn-up bladders to tension the ply endings of the unvulcanized carcass ply or plies as the ply endings are t...

A defect inspection apparatus having a television camera which picks up an object to be inspected and produces a video signal for inspecting defects on the object, wherein the apparatus comprises a detection section which outputs a signal responding to the positive changes of the video signal with respect to time and a further detection section which outputs a signal in response to the negative ch...

The invention provides herbicidal compositions containing as active ingredients (1) a 1,2,4-triazin-5-(4H)-one derivative of the general formula (I), in which R is amino or isobutylideneamino, and (2) a phenoxyalkanecarboxylic acid of the general formula (II), in which X is methylene or methylmethylene, R1 is chlorine or methyl and R2 is hydrogen or chlorine, WHICH MAY BE IN ...

A cyclopropanecarboxylic acid of the formula is prepared by the reaction of a compound of the formula with an alkali metal hydroxide or alkaline earth metal hydroxide in an ether type solvent. R1, R2, and R4 each independently is hydrogen or a hydrocarbon residue, R3 is hydrogen or lower alkyl, X is halogen, and A is -CH2-CX, 3 or -CH=CX2.

Hospital mattresses are generally made of foam plastic having predominantly open cell cores and are in the form of a parallel-epipedic block (1) which is provided with a protective layer (12 and 13) consisting of a plastic film which is easy to clean so that injurious substances and bacteria can be removed. Such mattresses have the drawback, however, that when used they produce sounds which are di...

The application deals primarily with the guidance and positioning of a travelling automatic servicing device (16) relative to a plurality of operating stations (12), e.g. of a spinning machine, which are to be serviced thereby. Aspects of the communication of information between the device and the stations are also dealt with insofar as they are associated with the guidance and positioning feature...

The invention relates to the butchery industry. The machine comprises notably: a vertical splitting carrier mobile along a first column, a mobile horizontal carrier on the splitting vertical carrier, a splitting blade carried by the horizontal carrier, a resilient dorsal guide mobile on a second column, two horizontal arms for encompassing the animal to be slit, rigidly connected to the horizontal...

A borehole is surveyed by positioning at the mouth of the borehole a survey instrument having a casing and a three-axis rate gyroscope unit mounted within the casing, and sensing at least two components of gravity in at least two mutually transverse directions with respect to the survey instrument by means of a gravity sensor unit. The survey instrument is then moved along the borehole with the st...

A method and apparatus are disclosed for assembling a protective boot in an air brake actuator. A mounting tube extends into the nonpressurized air chamber of the actuator and is formed with a groove in an outer peripheral surface. The end of the boot serves as a sleeve which is slipped over the end of the tube. A retainer ring, preferably carried by the boot, is forced downwardly to compress port...

In a disc brake the application of the brake is initiated by angular movement of at least one pressure plate with respect to a reaction member to cause the pressure plate to move axially into engagement with a friction disc which, in turn, is urged into engagement with a surface in a stationary housing. The angular movement is effected hydraulically by an actuator comprising a piston working in a ...

A simple, inexpensive and highly stable sit-up exerciser is disclosed having a horizontal frame and seat. The height and longitudinal position of the ankle-engaging portion of the device is adjustable relative to the seat and, where provided, the knee support, to suit the anatomy of any user.
