Abstract: A B S T R A C T     A device for manufacturing vehicle wheels having a rim which is wreath-shaped in cross section surrounding a cast wheel body is such that at least one die wall delimits the mould to be filled with cast metal. The prefabricated rim is laid between facing surfaces of a die plate and a centre plate, with the result that the die faces and the rim form the outer contours of the wheel body  when the mould space bet-ween the die faces and rim is filled with molten metal which is introduced under pressure. The rim itself is held by a clamping ring which can be removed in two pieces from the die assembly. A device for spraying a cooling medium onto the rim is provided on or in the clamping ring.     The rim features on its inner face a central strut  which is T-shaped in cross section, and on both sides of this side struts which are inclined outwards. The free ends of the side struts are displaced by the surface of the die plates.     (Fig. 1)

Abstract: IMPROVED MEANS AND METHOD FOR SENSING LOOM CONDITIONS INDICATIVE   OF POTENTIAL FABRIC DEFECTS             ABSTRACT OF THE DISCLOSURE      A first sensor comprising interspersed light emitting and receiving fibers is situated at the egress slot of an air containment element on a fluid weft insertion type loom and retroreflectively senses filling yarn as it egresses from the element. The first sensor, placed along the length of the air containment tube, together with a second sensor outboard of the shed is used to discriminate filling yarn condition and the impact of those conditions on fabric quality, Signals from the first and second sensors are employed in a logical method to permit continued operation of the loom when particular faults are sensed but do not represent conditions warranting stopping of the loom, while said sensors do produce loom stopping signals when faults of predetermined values are sensed. Loom output efficiency is thus improved by allowing a controlled number of defects to enter the finished fabric,

Abstract: ABSTRACT:           A data stream is received from a medium.  This stream consists of synchronization words and data words.  The synchronization words are either identical or one the inverse of the other when they are correctly received.  Between two synchronization words always a fixed number of n data words is present.  The information received is con-secutively stored in a buffer memory.  The buffer memory has connected to it a detection device for generating an instantaneous synchronization signal by way of a majority decision on at least three correctly received synchroniza-tion words.  Preferably, the buffer memory is a shift register comprising a data output which is situated approx-imately 1/2n data words + 1/2 synchronization word beyond the centre of the shift register when n has an even value.

Abstract: ABSTRACT OF THE DISCLOSURE         A push-button switch device for keyboards is provided with a multiple keyboard spanning several keys of the keyboard carrier plate and a support arrangement such that operation of the keybutton is balanced even though the key button switch may be positioned asymmetrically with respect to the multiple button.  The support arrangement includes a U-shaped guide bracket which is pivotally fastened on one side in the key-button and on the other side over the carrier plate.  A guide portion is positioned in a carrier plate recess adjacent to the key housing for the push-button switch and has the same shape as the key housing, enabling the guide portion to possibly be replaced by an actual key housing to rearrange the keybutton line-up in the keyboard.  The end of the guide bracket adjacent the carrier plate is connected to a support piece which is slidably supported over the upper surface of the guide portion.  A guide tongue extends beneath the keybutton through a guide aperture formed in the guide portion.  This arrangement serves to align movement of the key-button during activation of the push-button switch so that jamming of the push-button switch in a multiple button arrangement is prevented.

Abstract: ABSTRACT OF THE DISCLOSURE           The specification describes a device for interrupting high voltage electrical currents.  The device includes a stationary energized element and a movable energized element which is adapted to make contact with the stationary element in a first position.  The device has motive means for storing and rapidly delivering rotational energy which has been stored therein.  Input means are operable by movement thereof by an operator of the interrupting device for supplying rotational energy to the motive means for storing therein and for causing the motive means to rapidly deliver the rotational energy stored therein.          The device further includes overdrive means which has its output connected to the movable element and its input connected to the motive means.  The overdrive means is adapted to provide a greater amount of rotation at its output to the movable element than is received at its input from the motive means and is adapted to rapidly rotate the movable energized element independently of the rate of movement of the input means by the operator so that the arc plasma generated by the separation of the elements substantially traces the path of the movable energized element until the arc plasma is extinguished.     csm/

Abstract: A B S T R A C T    An exercise bench for use in performing free weight exercises which includes interconnected first and second tubular frame members which cooperate to provide a base frame for the planar benches which support the trainee.  The first frame member is substantially "U" shaped having transversely spaced apart upstanding legs which are interconnected by a rigid cross-member.  The second centrally disposed frame member having at least one ground engaging support leg and a longi-tudinally extending support element disposed in a crossing relationship with the rigid cross-member of the first frame.          This longitudinally extending support element supports the fixed and an adjustable planar bench portions which portions are hingeably interconnected together.  The adjustable bench portion can be adjusted into several angular orientations with respect to  the second frame member and can be locked into position by a unique, multipurpose stabilizing assembly which functions to rigidly connect together the first and second frame members and also to pivotally carry a bench support member adapted to locate and support the sloping, adjustable bench portion.  The unique design of the stabilizing assembly provides substantial support to the unit against lateral and twising forces impressed upon the device and at the same time functions to permit quick and positive adjustability of the slope of the adjustable portion of the bench.
