Abstract: ABSTRACT      A diamond abrasive wheel for use on stone is made up of a back-up support to be fixed on the driving spindle of a hand grinder. On the support there is a ring-like plate, made up of bonded diamond dust and able to be un-done from the support. The working face of the plate has coolant grooves sloping in the direction of turning. For producing the best possible relation between the size of the area of the working face and the force used for pushing the wheel against the work, the abrasive wheel is so designed that the plate has groove-like hollows between the coolant grooves for decreasing the acting abrasive face, these groove-like hollows being of such a design that,when the abrasive or working face is running on the work, it is not possible for the coolant to make its way from the middle of the wheel in an outward direction because the hollows are filled with a soft compound completely, or only at their inner and outer ends, up to the level of the working face.

Abstract: STRUCTURE FOR MOUNTING BACKPLANE APPARATUS          Abstract of the Disclosure Holding members in mounting apertures of certain types of apparatus in cooperation with shoulders on backplane wiring pins secure the apparatus to the pins. The pins are inserted through the apertures.  A holding member is formed of a tapered wall surface of an aperture which form a constriction in the aperture.  The wall bearing the holding member is made of an elastic material which flexes to allow the shoulder of a pin to pass the holding member during insertion.  After the shoulder passes the holding member, the wall conforms substantially to its original shape and locates the holding member behind the shoulder to hold the apparatus in place.  The invention solves the prior problem in which apparatus frictionally mounted on the pins loosen in time due to "stress relaxation" of the apparatus material.

Abstract: Abstract A transmission system comprises apparatus for the transmission of voice signals only, data signals only, or a combination of both voice and data signals in a multiplexed stream of eight bit time slots over a single, bidirectional digital channel for a point-to-point connection.  In the combined mode, the encoded voice signals, using low bit rate voice encoders, are assigned to four bit positions of the eight bit time slot; the data signals are assigned to the remaining four bits.  Up to two bit positions normally used for data may be used for signature bits, thereby identifying whether the multiplexed stream comprises voice signals only, data signals only, or a combination of both voice and data signals.  Also, a minimum of one "1" bit per eight bit time slot is thereby guaranteed.
