Abstract: SCROLL TYPE FLUID DISPLACEMENT APPARATUS            ABSTRACT    A scroll type fluid displacement apparatus including a housing, a pair of scroll members each comprising an end plate and a spiral wrap means projecting from one surface of the end plate. Both wrap means are interfitted to make a plurality of line contacts between them,and a driving mechanism including a drive shaft is connected to one of the scroll members to effect orbital motion thereof relative to the other (fixed) scroll member while rotation of the orbiting scroll is prevented. The center portions of the wrap means are make thicker than the remaining portions thereof, the center portions extending substantially from the inner ends of the wrap means outwardly at least throughout the portions thereof which contact one another when the two innermost fluid pockets are merged into a single fluid pocket to form the high pressure space near the center of the scroll members. This construction insures sealing of the high pressure space from adjacent fluid pockets, keeping volumetric efficiency and horsepower requirement of the unit to a certain level under a limited accuracy of machining the spiral elements.

Abstract: INVENTOR:  JACQUES MEIER            INVENTION: METHOD AND APPARATUS FOR THE INSERTION OF AT LEAST            ONE INSERT OR SUPPLEMENT INTO PRINTED PRODUCTS     ABSTRACT OF THE DISCLOSURE              In each case two printed products conjointly travel through a processing path which starts at an input or infeed section and terminates at a removal or withdrawal section.  At the infeed section an opening is produced in one of these printed products by the action of a pressure element which exerts a pressure or force transversely with respect to the plane of the printed products.  During the forward advance of the printed products in a subsequently arranged feed section the opened printed product travels onto a separation element, such as a separation wedge, by means of which such printed product is opened.  There is stuffed an insert into the opened printed product.  At this first feed section the other printed product, which up to this time merely travelled along, is opened by means of a further pressure element.  During the further advance of the printed products the second printed product is likewise opened by a separation element, for instance a separation wedge, which engages into the previously formed opening of this other printed product.  At a second feed section there is now likewise stuffed an insert into the open second printed product.  The final products, each of which have been provided with a respective insert, are now removed from the removal section for further processing.  With a given processing speed the output of the equipment is increased due to the simultaneous travel or passage of two printed products through the stuffing device.

Abstract: METHOD FOR RECORDING DIGITAL SIGNALS ON MULTIPLE               TRACKS OF A RECORDING TAPE                 ABSTRACT OF THE DISCLOSURE        Disclosed is a method for recording digital signals on multiple tracks of a recording tape.  Audio signals are quantized into digital signals are formed into data words and organized into a plurality of parallel rows which are adjacent to each other and respectively correspond to those tracks which are remote from an edge of the tape.  Parity words are derived from the data words and organized into a row which is parallel to the rows of data words and corresponds to the track which is close to the edge of the tape.  An error detecting check word is generated and appended to the end of each of the rows of data and parity words.  A synchronization word is also generated and appended to the beginning of each of the rows of data and parity words.  By the arrangement of the parity words along the same row or track adjacent to the tape edge, the probability of occurrence of incorrectable errors is reduced.

Abstract: A PROTECTIVE COVER ASSEMBLY FOR A GREASE FITTING    Abstract of the Disclosure A protective cover assembly is disclosed for a grease fitting formed on the universal joint of a Cardan shaft.  The assembly includes a cover plate, a support member and a slideable sleeve.  The cover plate projects outward from a gear case and encircles a portion of the Cardan shaft which is connected between the gear case and a transmission.  The support member straddles the cover plate and is attached to the gear case such that it encircles a portion of the Cardan shaft and is aligned adjacent to the universal joint. The support member has a stepped outer surface with a radially aligned attachment mechanism formed on the smaller diameter surface.  The slideable sleeve protrudes onto the smaller diameter surface and the attachment mechanism cooperates with a mating surface on the sleeve to form a quick attachable and releaseable fit between the two parts.  When the sleeve is secured to the support member, the universal joint is completely enclosed and protected from contamination and when it is necessary to lubricate the universal joint, the sleeve is slid back thereby exposing the grease fitting.
