Abstract: SAFETY LATCH FOR AUTOMOTIVE HOISTS OR THE LIKE               Abstract of the Disclosure The disclosed safety latch is operable with automotive hoists that have a rack gear connected to and movable with the hoist piston.  The piston, which carries the hoist superstructure, is disposed in a cylinder so that the piston telescopes to raise and lower the hoist in response to hydraulic or pneumatic pressure acting thereon.  A pinion gear-mounted on the latch is in engagement with the rack and, through a slip clutch mechanism, drives an operating lever that is connected with a latch dog for securely engaging the rack to prevent movement of the rack and the piston downwardly with respect to the cylinder.  The latch operating mechanism can be operated manually to completely dis-engage the latch dog from the rack whereby the hoist may be lowered.  The slip clutch mechanism is provided with a lost motion coupling  member between the latch operating member and the latch dog so that the latch dog remains in engagement with the rack should the system for raising the hoist become inoperative.                             -1a-

Abstract: DATA STORES AND DATA STORAGE SYSTEM     ABSTRACT OF THE DISCLOSURE              In a Teletext transmission system, data is transmitted in digital form during lines in the field blanking period of a composite video signal of a tele-vision transmission.  On reception, the information is decoded and utilized to provide a display comprising a page having a predetermined number of rows of information in alphanumeric or graphics form.  The data is received in blocks comprising information digits and each block has an associated group of address digits so that each block can be directed to an appropriate storage location in a first store, regardless of the order in which the data blocks are transmitted.  The contents of the first store can then be transferred in address order into a larger capacity serial store ready for use in generating the display.  Thus it is possible for a number of pages of information data to be correctly assembled in serial row order, ready for display generation, in a manner accommodating non-transmitted blank rows.

Abstract: A B S T R A C T        A digital-to-analogue converter which uses a technique of two-level quantisation in order to generate a pulse density modulated signal which yields the analogue signal when filtered.  Standard digital logic adders and registers are used in the conversion of PCM signals to the pulse density modulated signal.  The adders and registers are arranged as a feedback loop in which an approximation signal capable of either a "high" or a "low" level is compared repetititively with a PCM signal and the difference is accumulated but at the end of each operation the accumulated total is tested and the value of the approximation signal for the next cycle is chosen so as to reduce the accumulated total.  The cycle period is set by a clock and the approximation signal is the pulse density modulated signal.  The noise spectrum of the pulse density modulated signal may be adjusted by the addition of an offset signal to the incoming PCM signal.  The digital-to-analogue converter is suitable for use in converting linear PCM telephone speech signals into analogue signals.

Abstract: ROTARY ENERGY STORAGE DEVICE                         Abstract A rotary energy storage device comprises a rotor and a hub for mounting the rotor on a shaft. The rotor is joined to the hub by an interlayer disposed between the rotor and hub.          One surface of the interlayer is bonded to a mounting surface of the hub. A second surface of the interlayer, which is opposite the first surface, is bonded to a surface of the rotor which is opposite and spaced from the mounting surface of the hub. Due to differences in their constructions, such as their relative di-mensions, the rotor and the hub experience different strains due to the centrifugal forces exerted during rotation of the energy storage device. The difference between the strain at the mounting surface of the hub and the strain at the opposed surface of the rotor induces a shear stress in the interlayer. To accommodate the induced shear stress, the interlayer has a thickness and a shear modulus which permit the interlayer to deflect in response to the difference in strains without structural or bond failure. The interlayer can be effective to accommodate the induced shear stress at any speed of the energy storage device up to the speed at which the rotor would fail due to centrifugal loads imposed upon it. The interlayer is preferably formed of a body of elastomer and is preferably bonded to the hub and rotor adjacent an area of max-imum strain differential between the hub and rotor.
