Abstract: 1345636 Battery connectors ESB Inc 18 Jan 1972 [12 Feb 1971] 2389/72 Heading H2E [Also in Division H1] In a battery having electrodes 20 or 22 connected by a strap connector which is joined to a terminal connection 32 sealed into and extending through a side wall 14 of casing 10, the terminal connection 32 is in the form of a bayonet type socket to receive and locate a complementary bayonet type plug connector 34 of a battery cable 38. As shown, terminal connection 32 comprises a tubular portion 50 provided with a pair of inwardly directed acuate flanges 44 which are of tapered thickness. The end 36 of cable 38 is secured to plug connector 34 by a bolt 40 and intervening washer 42. The connector 34 comprises a pair of arcuate flanges 46 of tapered thickness and a disc like surface 56. The plug connector 34 is inserted into socket terminal connection 32 so that its flanges 46 lie between flanges 44 of terminal connection 32. It is then rotated so that flanges 46 slide behind and grip flanges 44 and pick-up disc like surface 56 engages the outermost surface of connector 32 and face 54 engages the bottom 48 of connector 32. The end connector 34 may be rigidly attached to cable end 36 as shown so that it is rotatable by rotation of the cable end. Alternatively, the end connector 34 may be rotated by means of bolt 40 relative to cable end 36. The terminal connector 32 may be formed integrally with the strap connector.

IPC: A62C13/00
Filed: 1917-02-27
Abstract: 104,680. Pearson, G. T. March 10, 1916, [Convention date]. Extincteurs.-A chemical fire-extinguisher comprises a vessel 3 containing carbon tetrachloride or other fire-extinguishing liquid, which is ejected therefrom by means of gas generated in the chamber 11 and dried and freed from acid by means of a substance such as anhydrous sodium carbonate in the chamber 12. In the casing 7 attached to the lid 5 is mounted a vessel 11, containing sodium bicarbonate, within which is a second vessel 15 containing hydrochloric or sulphuric acid and provided with outlet pipes 16. On inverting the apparatus, the sodium bicarbonate falls on the lid 5 and the acid drops through the tubes 16, the vessel 15 being prevented from dropping against the lid 5 by means of the rod 17. The gas generated passes through the gauze screen 18 and is dried and freed from acid by means of anhydrous sodium carbonate in the chamber 12, from whence it passes through the pipe 9 and check valve 10 into the chamber 3. To prevent the soda from passing into the vessel 3, the pipe 9 is provided with a perforated cap 19 and gauze strainer 20. In order that the liquid may be ejected in any position of the container, the outlet nozzle 22 is supplied with liquid by means of a tube 24 mounted to rotate about the axis of the apparatus and carrying a tube 35 closed at its upper end by a ball valve 30 in the cage 28. Co-axial with this tube is a tube 36, the inlet to which is also controlled by a ball valve 31. In a modification, the outlet pipe is carried through the apparatus to the top, the ball valves 30, 31 are connected by a rod and the cages dispensed with, and the acid chamber 15 is held fired by means of the rod 17.

Filed: 1925-02-05
Abstract: 231,838. Soc. du Carburateur Zenith. April 2, 1924, [Convention date]. Spray carburettors. - In carburettors having double or multiple Venturi passages, excessive cooling of these passages and a consequent deposition of ice thereon is prevented either by providing them with double walls, the space between which contains a heating medium, or bv heating the air supplied to one or more but not all of the passages. The upper end of the Venturi 1, Fig. 1, terminates slightly above the most constricted part of the Venturi' 3 and its upper part a is surrounded by a wall b to form a space 4 to which hot exhaust gases are led through a conduit 5. The gases escape into the mixture stream, and thereby raise its temperature, through the annular space 6. Fuel from a conduit 7 issues through orifices 8. The application of this method of heating to an intermediate passage in a carburettor having more than two Venturi passages is shown in Fig. 2. In the modification shown in Fig. 3, hot water from a reservoir 18 is circulated by passages 14, 15 through the space 13 between the Venturi c and the wall d. Fuel from the conduit 16 is discharged through orifices 17. In a further modification, the heating space contains an electric resistance wire. Both the hot water and the electric method of heating for double Venturi passages, are modified for multiple passages in a manner corresponding with Fig. 2. The air supply to the inner Venturi passage 1, Fig. 7, may be drawn through a pipe 27 from a space 30 surrounding the exhaust pipe 31. Fuel from a conduit 32 is discharged through orifices 33.
