Abstract: 562,925. Fuel pumps. STEVENS, A. H. (Thompson Products, Inc.). Feb. 10, 1943, No. 2227. [Class 110 (i)] A fuel pump for aircraft &c. is mounted in a tank 11 formed between the upper and lower skins 14, 15 of the aeroplane, the support comprising a bracket 111 ... 113 fixed to the wall 13 and to an inset portion 110 of the skin 15. The motor 10 is in a liquid-tight casing connected to the pump casing 25 by a channel through which passes the lead 58 to the motor and which forms an inlet for cooling air drawn in to the motor casing by suction produced in a pipe 108 projecting into the slip stream from the space 69 between the motor or pump casings. The shaft 63 connecting motor and pump is sealed against leakage by a flexible ring 81 pressed between a fixed annulus 79 seated on a shoulder 68 and a screwed sleeve 82. In addition, a graphitic carbon ring 85 rotating with the shaft has sliding contact with 79, and is packed by a resilient washer 86 pressed against it by a spring 92 abutting on a cup 87 housing the washer. A flame barrier between the motor and pump comprises a sleeve 72, 74 loosely surrounding the shaft and a second sleeve 77 spaced from 74 and having a portion 76 gripping the shaft so as to rotate therewith. The shaft 63 is keyed to the impeller 91 by curved keys 98 engaging curved slots 96, 100 in the impeller and shaft respectively. The pump casing, has a cap 34, by removing which the impeller may be removed from the shaft. The inner parts 126 of the impeller blades 127 agitate..the entering fuel and separate bubbles of gas which pass up through the fuel in the tank and escape by the vent 21<1>. The fuel is delivered by pipes 28, 29.

Title: Improvements in or relating to electric accumulators
IPC: H01M10/18
Filed: 1926-01-30
Abstract: 256,569. Deodato, E. Aug. 7, 1925, [Convention date]. Electrodes; separators; supports for electrodes. - Accumulator electrodes of the bi-polar type consist of plates of insulating material or of metal covered with insulating material, the active material consisting of separate elements secured to one or both sides of the plates. Fig. 5 shows a part of an electrode, the supportins plate 11 being made of steel covered with aluminium 12 and celluloid 13. One active element is shown on each side of the plate, each element consisting of a piece of lead 14 formed with gills between which active material may be placed, the two elements being connected by a rivet 15. Fig. 1 shows a battery in plan, the end plates 11 having active elements on one side only. In order to prevent short-circuiting the elements 14 are arranged in staggered formation. The electrodes are clamped between U-shaped wood frames 16, thus forming a number of cells adapted to contain the electrolyte. The frames are protected by coatings of rubber and celluloid and are clamped by bolts between wooden end plates fitted with metal reinforcements 21 as shown in Fig. 4. These reinforcements extend upwardly to form attachments for handles 24 and downwardly to retain wooden members forming a support for the accumulator. The plates are provided at their upper ends, as shown in Fig. 3, with lugs 26 which rest on fibre strips 27 on the tops of the frames 16 and the cells formed by the plates and frames are closed by covers 28 having ventilating openings as shown in Fig. 4. The end plates are connected by copper bolts 31 to metal blocks 30 provided with bolts 33 to which the external connections are made. In order to facilitate removal of the electrodes they are formed with slots 34 with which a hooked tool can be engaged. The electrodes may be of the unpasted or pasted type employing lead, copper, ferro-nickel &c. as the active material. The Specification as open to inspection under Sect. 91 (3) (a) states that instead of being bipolar the electrodes may be joined in parallel in two groups in the ordinary way. In this case the plates are made of metal to which the active elements are joined electrically. This subjectmatter does not appear in the Specification as accepted.

Title: Method of removing the heat developed in the individual cells of an accumulator
IPC: H01M10/50
Filed: 1975-01-22
Abstract: 1461366 Accumulator cooling systems VARTA BATTERIE AG 22 Jan 1975 [27 March 1974] 2801/75 Heading H1B [Also in Division F4]  Apparatus for removing the heat developed in the cells 2 of an accumulator comprises a hollow heat exchanger 3 immersed in the electrolyte in each cell, the heat exchangers being made of electrically insulating material and connected by pipes 5 to a pump 7 for circulating a cooling medium through the heat exchangers. The heat exchangers 3 consist of coils or bags preferably made of polyethylene but polypropylene, polyvinylchloride or glass may be used. Fig. 5 shows a series-parallel arrangement of heat exchangers in which the cooling medium used is normal water. Initially, if the temperature of the cells is low, a temperature sensor 11 controls a valve 9 to pump the water through a line 10 in order to by-pass a heat exchanger 6. A temperature sensor 13 switches on a heating element 17 to heat the water provided that a sensor 16 has supplied a signal to an actuator 14 to indicate that an external supply source is available for the heater 17. As the cells warm up, the sensor 13 switches off the heater 17 and the sensor 11 operates the valve 9 to divert the water through the heat exchanger 6. Further cooling of the water is provided by a fan 8 controlled by a temperature sensor 12. Fig. 7 shows a system in which the heat generated in the battery 30 of an electrically driven vehicle is used to heat the vehicle passenger space. The system includes a compressor 21 for further heating the circulated water, valves 41-46, a heat exchanger 33 in the passenger space heating plant 32, an expansion element 23 for cooling the water, a heat exchanger 36 mounted outside the vehicle and a heat storage plant 38, the heating element 40 of which can be supplied from an external source. The system also enables the heat removed from the battery to be stored in the plant 38 and used for heating the passenger space, and the passenger space may be cooled using the external heat exchanger 36. In a modification the cooling medium circuit comprises a portion associated with the battery and in which water is circulated, and a portion associated with the vehicle but in which a halogenated hydrocarbon is circulated, the two portions exchanging heat in a heat exchanger.
