Means for coupling an independently suspended medical x-ray source and detector for lateral fluorographic studies such as angiography. When coupled, the x-ray source and detector move vertically in opposite directions, move horizontally toward or away from each other, and pivot about horizontal axes so the distances between the focal spot and isocenter of examination and between the isocenter and ...

A manually powered winch has two geared drive trains. Both originate from a simple set of gear teeth (7) formed into the diameter of a drive input shaft (5). The final drive, common to both gear trains, to an internal gear track (18) on the drum (3) of the winch is one part (12) of a two-part gear (8,12). The part (12) is directly borne by a hub (20) on an axle (10) in the winch. Its gear teeth ar...

This invention concerns improvements to procedures to splice yarns (20-21), whether textile yarns or otherwise, the splice being obtained by coupling two single untwisted yarns (20-21) and by reconstituting the twists thereafter, by which improvements a part of the single yarns (20-21) is untwisted until twists of a sign opposite to the sign of the original twists have been imparted, such part the...

In a vehicle drive system having a longitudinal engine and a transaxle in line therewith, a speed-up mechanism is incorporated in the transaxle in place of a differential mechanism so as to increase output speed of an output shaft of the transaxle.

There is disclosed a mechanical type of device, effective to suitably spread apart the new tread rings to be applied on the carcasses of worn tires, in the retreading process thereof. The device comprises, substantially, a base (1), bearing a horizontally extending shaft (3) effective to rotate about the axis thereof and at one end thereof there is keyed a bevel gear wheel (5). The latter meshes...

A method of analyzing a liquid sample by applying the sample to a composite test paper composed of a strip plastic transparent film and a reflectivity reference or compensation paper piece and a plurality of color reaction test paper pieces affixed to the strip, feeding the test paper to a spectral reflectivity measuring device a predetermined period of time after the application, and calculating ...

The dressing device is for grinding wheels and involves a disc (3) with embedded diamonds and which is rotated by means of a motor (8). A surface line in the grinding wheel (2) and one in the dressing disc (3) lie in the same plane, and have a point contact with one another, with an angle (9) being formed at their point of contact.

A system is described for recognising a data word in a serially presented data stream by comparing the currently presented data with a predetermined datum word. The bits of the presented data are fed into the stages A to L of a shift register 6 which correspond to respective bits of the datum word. A monitoring unit 16 monitors the states of only those stages (stages D,G,I and K) corresponding to ...

An "Automatic Exit Delay" circuit of a burglar alarm is placed on Stand-By whenever a "first" door is opened and the burglar alarm automatically starts to work right after the "last" door is closed. At that moment of arming a "Quiet Quick Test" Network automatically tests the alarm for proper functioning and generates a short "beep" to indicate such as well as the armed state of the alarm system.

A mixing method and apparatus for preparing multi-component plastic materials, especially polyurethanes, which are mixed before being fed into a mold. According to the invention, a first and at least a second main component are mixed by feeding them into a limited area of a mixing chamber through lateral inlet apertures symmetrically arranged with respect to a plane comprising the longitudinal axi...

1. A system for diluting highly viscous solutions of blood constituents, comprising a container (1) which is filled with a diluent sterilized therein, and, adjacent thereto, a connecting member (3), provided with a puncturing spike (5), for supplying the diluent to preserved blood consisting of a highly viscous solution of blood constituents, as well an interposed closure member (6, 13) which is t...

The invention relates to an electromagnetic safety brake with a fixed electric annular coil and an axially displaceable annular armature and, furthermore, with spring means acting annularly on this armature so as to move the armature into its braking position in the de-energised condition of the coil, these means being designed as resilient annular diaphragms and exerting on the armature a force u...

A disk clutch inserted between a torque converter and a synchromesh gear train of an automotive transmission comprises a driving friction-plate carrier coupled with the turbine of the converter and a driven friction-plate carrier coupled with an input shaft of the gear train, the driving carrier forming two fluidically separated concentric cylinder spaces between itself and an operating piston emb...

An installation for damping vibrations in the drive connection of a motor vehicle by a vibration absorber which includes, in coaxial arrangement with the cardan shaft, an annular vibrating mass, a carrier flange adapted to be secured to the cardan shaft, and a resilient body of an elastomeric material which effects the vibration coupling of the vibrating mass with the carrier body of the carrier f...

Films especially useful for the stretch wrapping of pallet loads are prepared from compositions consisting essentially of a linear low density polyethylene resin free of any polymerized vinyl acetate groups and from about 0.3 to about 3.0 wt % sorbitan monooleate based on the weight of the resin.

The actuator comprises a piston (34) which has a stepped portion (36) formed with an annular groove (38) at its end projecting out of a cylinder (16). An annular protective sheet (50) is slipped on the stepped portion (36) and it comprises at its radially inner edge (52) inwardly projecting, resilient tongues (54) which are arrested in the annular groove (38).
