Title: Improvements relating to internal grinding machines
IPC: B24B47/06
Filed: 1933-07-19
Abstract: 415,879. Internal-grinding machines. CHURCHILL MACHINE TOOL CO., Ltd., Broadheath, Manchester, and ASBRIDGE, H. H., Reigate, Moss Lane, Aston-on-Mersey. July 19, 1933, No. 20362. [Class 60.] In an internal-grinding machine of the type in which the work table a is traversed to operative position by hydraulic means, which then hold it against a reciprocating stop c which gives the table short and rapid to-and-fro movements during grinding, the stop c is mounted on a spring-loaded slide c<1> in a carrier d pivoted at e and operated by power means which, in the form shown, comprise a crank f and connecting-rod g. A loaded release valve r<1> allows the piston of the hydraulic operating cylinder to be moved by the oscillating stop c. As the table a moves towards the operative position the stop c rides up an incline h on a bracket i, the upward movement causing it to operate, through a projecting portion j, a valve which diminishes the supply of fluid to the operating cylinder to lessen the speed of the table.

Title: Digital actuator
IPC: G05D3/18
Filed: 1964-05-19
Abstract: 1,060,745. Stepping-motors. CONOFLOW CORPORATION. May 19, 1964 [May 16, 1963], No. 20666/64. Heading G4H. A bidirectional stepping motor is controlled by logic circuitry which receives step-command signals and signals representing the current state of energization of the motor. The step-command signal may be a pulse on one of two lines (P, N) depending on the polarity of an error signal from comparing required and actual liquid flow rates, the motor controlling a valve. The current-state signals from the motor may come from taps (for voltage reduction) on resistor chains connected in parallel with the motor windings. The outputs of the logic circuitry are sampled with a strobe signal (G) derived from the error signal, and used to control flip-flops via monostable multivibrators. The flip-flops control motor winding energization, optionally through NPN transistors (Fig. 7, not shown) or silicon-controlled rectifiers (Fig. 8, not shown). The logic circuitry may utilize AND-gates, or tunnel diodes (which give an output for one or three inputs present but not for none or two). By altering change-over switches, the error signal may be replaced by a constant signal of selected polarity present as long as a manual control is kept actuated, and/or the strobe signals may be produced at a constant rate by an independent generator.

Title: Method of moulding tires
IPC: C08G73/02
Filed: 1955-07-20
Abstract: The walls of the moulding cavity in a tyre mould are coated with polytrifluoromonochloroethylene to prevent the rubber of the vulcanized tyre from sticking to the mould without the use of mould dopes and dusts.  The polymer may be used alone or modified by compounding or blending it with phenol aldehyde resins, e.g. phenol formaldehyde, or epoxy resins, e.g. epichlorohydrindiphenylol propane.  The polymer is dispersed in a suitable solvent.  Before coating the inner surface of the mould it is heated to remove traces of oils and organic matter and then sandblasted to give a fresh metal surface.  The dispersion, e.g., polytrifluoromonochloroethylene in a xylene-diisobutyl ketone solvent, is sprayed on the surface, the solvent removed by evaporation and the mould heated to fuse the polymer into a continuous coating.  A satisfactory thickness for the coating is 0,003 in.  The coating may be applied in layers, which may be of different composition using the compounded dispersions, a satisfactory coating comprising an inner layer relatively rich in epoxy or phenolformaldehyde resin and poor in polytrifluoromonochloroethylene and an outer layer of opposite proportions.  The advantage of the coating applies to all kinds of rubber, including rubber-like materials made from polyesters modified with polyisocyanates.
