Title: Improvements relating to drivers' brake control devices for electro-pneumatically controlled fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1935-12-14
Abstract: 467,215. Fluid - pressure brakes. KERSHAW, A. G., SIMMONS, A. W., LEECH, K. H., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Dec. 14, 1935, No. 34782. [Class 103 (i)] In a self-lapping driver's control device for an electropneumatically controlled brake system wherein a floating lever is connected to the hand lever, to the electric contacts of the valves and to an abutment subject to the brake cylinder pressure an arm 5 on the shaft 2 of the hand lever 1 is connected by link 7 to the floating lever 9 which is connected by link 11 to a lever 13 on a fixed pivot 15. The upper arm of the lever 13 carries on a member 17 contacts for engagement with contacts 18 connected respectively to the holding or release valve and the application valve respectively. The lever 9 is pivoted also to a rod 21 slidable in the rod 22 of a piston 23 subject to brake cylinder pressure through passage 26 and to the pressure of a spring 28. A spring 36 is interposed between collars 29, 30 slidable both on the rod 21 and within the piston rod 22. Normally, as shown, one contact 18 is engaged to energize the holding valve which is thus open to release the brake. Initial movement of the handle 1 effects a rapid movement of the member 17 by reason of the inequality of the arms of the lever 13 to deenergize the holding valve and energize the application valve, the lever 9 turning on the pivot 19. The lever 13 then abuts on a stop and with continued movement of the hand lever, the lever 9 turns on pivot 10 withdrawing the rod 21 through the piston rod 22 and compressing the spring 36. The piston 23 under the action of the cylinder pressure follows up the rod 21 until the rods 21, 22 are in the original relative position and further movement of the piston is then transmitted through the spring 36 to the rod 21 turning the lever 9 on the pivot 8 to reverse the movement of the member 17 to a position in which both contacts 18 are disengaged and both valves closed. The cylinder pressure established is thus dependent upon the extent of movement of the hand lever. Graduated release of the brake is similarly effected. The shaft 2 may carry a rotary valve which may for instance effect the release of fluid from an automatic brake pipe to effect an emergency application of the brakes or may control connections to a driver's valve to permit pneumatic control as an alternative to electric control of the brakes.

Title: Display device for indicating the progress of production processes
IPC: G07C3/12
Filed: 1962-09-13
Abstract: 960,299. Signalling systems; production display systems. SIEMENS & HALSKE A.G. Sept. 13, 1962 [Sept. 14, 1961], No. 35034/62. Headings G4F and G5C. A display device for indicating the progress of production processes includes an arrangement for moving one or more indicators K1-K6, corresponding to one or more production tasks and bearing information identifying the particular task concerned from a starting position to a finishing position, the relative position of the indicator defining the progress of the relevant task. The arrangement includes a step by step drive operated by an electric pulse emitting device controlled from the location where each relevant production task is being performed. The actuating circuit (Fig. 5) for each indicator contains a switch sh operated either manually or automatically at the location of the relevant task. This operates a pulse generator TG which may consist of a timer ZG and a pulse emitting contact ig. When the contact ig closes the magnetic coupling MK is operated, allowing a synchronous motor to be coupled so as to drive the indicator. This is achieved by oringing into action a belt B which drives against the indicator card. The card contains a series of holes through which a feeler fk makes contact with a metal supporting plate W. The feeler and plate are connected into the actuating circuit so that when no contact is being made (i.e. the indicator card is moving between two positions) a relay R operates, closing the contact r and allowing the magnetic coupling MK to continue operating. When the card reaches its next stopping position the feeler fk short circuits the relay and the indicator card will not move until a further signal is received from the operating switch sh.

Abstract: 847,141. Balanced flues ; incandescent gas fires. GAS COUNCIL. Feb. 11, 1959 [Nov. 14, 1957], No. 35523/57. Class 126. [Also in Group XIII] In a gas fire having a convection air heat exchanger 5 associated therewith, and which includes a casing 1 with a translucent front panel 2 of heat resisting glass, and a firebrick backing 3 in front of which is an open-work radiating element 4, combustion air for the burners 12 is supplied through a separate passage which communicates at both ends with the flue or other space into which the burner gases are discharged. This arrangement it is stated promotes a substantially constant flow of combustion air to the burners. In all the forms of apparatus described, room air entering the apparatus at 17 is caused to flow by convection over the heat exchanger 5 and is thereby heated before passing out through a perforated front panel 10. The form of apparatus shown is for use with a balanced flue in which the combustion air inlet 15 and burner gases outlet 8 are adjacent. Combustion air flows from the inlet 15 down the passage 14 to a duct 16 leading to the burners 12 from which the burner gases flow upwardly through the heat exchanger 5 to the flue 8. Combustion air may also enter the duct 16 through an opening in the wall of the duct 14, Fig. 1 (not shown). In a further form described, Fig. 2 (not shown), the duct 16 is extended to form the only combustion air inlet the passage 14 and inlet 15 then being sealed off. The construction may be such that a single apparatus is readily adaptable for entry of the combustion air in accordance with any one of the embodiments described above.
