Abstract: ABSTRACT OF THE DISCLOSURE        A three-mode, hydromechanical transmission including a pair of hydraulic displacement units forming a hydrostatic transmission and having a first, low-speed hydrostatic mode and a second and -third intermediate and high speed hydromechanical modes.  In one embodiment, a pair of planetaries are related to form a four-element differential and are associated with an input shaft and the hydrostatic transmission and brake and clutch means.  The hydrostatic transmission drives an output shaft through a connection to one of the planetaries, with the brake means engaged.  A first clutch means in a drive train from the input shaft to one planetary effects the second mode of operation with the brake disengaged and a second clutch means in a parallel drive train to another element of the planetaries effects the third mode of operation, with the brake and first clutch means disengaged.  In another embodiment, tnree planetaries are utilized to provide the same three modes of operation, with an extended third mode and with the brake means connected to an element in at least two of the planetaries and with one of said drive trains also being connected to an element in more than one of the planetaries.

Abstract: Abstract of the Disclosure Described herein, is a pigment paste for use in an aqueous paint comprising a film-forming latex polymer, a pig ment and a dispersant copolymer.  Also described is the dispersant copolymer which serves the function of dispersing the pigment in the preparation of the paste and maintaining the dispersion in the paste and paint made therefrom.  The dispersant copolymer is such that its complex salt formed with Zn++ and ammonia is water-soluble at a pH of 9.6. The dispersant is a copolymer of an .alpha.,.beta.-unsaturated monovinylidene carboxylic acid and at least one other ethylenically unsaturated monomer.  The dispersant is particularly adapted to preparing paste for difficult-to-formulate paints such as paints with re-active pigments and paints requiring high levels of dispersant.

Abstract: ABSTRACT OF DISCLOSURE         Sign lettering materials are described which consist of plastics film letters releasably adhered to a split backing tile, e.g. of silicone coated card, by a permanently tacky pressure-sensitive adhesive.  In order to assist proper spacing of these letters (and numbers) when they are set up to form words, in the case of at least some of the letters of the alphabetic set, one or more corners of the tile has a stepped notch with one or more steps.  The inmost vertical sides of the notches are abutted to give the desired spacing, consistent with the letters not overlapping.  The system allows visually even spacing to be rapidly achieved over a range from closely spaced letters to wide spacing.

Abstract: AIR PUMP WITH PRIMARY AND SECONDARY          INLET FLOW CHANNELS                 Abstract of the Disclosure An air pump useful in pumping gases containing abrasive particles is disclosed.  A housing is constructed with a primary flow channel centered around the pump axis and a secondary flow channel annularly surrounding the primary channel just inside the outer housing wall.  Within the midsection of the pump a powered impeller rotating within an axially symmetric shroud accelerates air drawn from the primary flow channel causing it to be discharged through an annular shaped ejector nozzle into a suction chamber.  Presence of the high velocity airstream in the suction chamber draws the contents of the secondary flow channel into the suction chamber.  The entrained contents of the primary and secondary flow channels are carried into the diffuser where the velocity energy of the mixture is converted into pressure.  The pressurized mixture is then discharged through the exhaust section.

Abstract: RCA 74, 436 IMPROVED DIGITAL ON VIDEO RECORDING AND PLAYBACK SYSTEM           ABSTRACT In a system for recording digital information on a video disc and for playback of the digital information therefrom, the digital data is recorded in synchronism with the color subcarrier signal on a horizontal line adjacent to a constant luminance line. This arrangement facilitates a video disc player having a simple, efficient, video-to-digital interface for separating the prerecorded digital information from the video signal. The player apparatus is responsive to the color subcarrier signal and the chrominance-related output signal of a comb filter, both of which are normally available during video signal processing. Prerecorded digital information representing field number and type of program content is used by a microprocessor controller to provide player features such as locked groove detection, program elapsed time display, and end of program indication. The microprocessor-to-player interface includes means responsive to the panel controls to operate the player mechanism and panel displays in accordance with the desired player features.
