Title: Improvements in Vehicle Air Conditioning Systems
Inventor: BROWN DENNIS COCKBURN
IPC: B60H1/32
Filed: 1966-02-11
Abstract: 1,181,066. Thermoelectric devices. ASSOCIATED ENG. Ltd. 10 Feb., 1967 [11 Feb., 1966], No. 6233/66. Heading H1K. [Also in Division F4] A vehicle air conditioning system comprises a number of thermoelectric devices 1 of which the cold junctions 2 are in thermal contact with a lagged tank 8 containing water so that on passing a current through the devices the water freezes. Subsequently air from a motor driven fan 9 is passed in heat exchange with the ice so formed to provide a supply of cooler air for the vehicle. The devices 1 may be semiconductors. The air flow from the fan is controlled by an arrangement of shutters which in the changing condition shut air off from the tank and allow air to dissipate heat from the hot junctions 4 in an air duct 5. The changing cycle is terminated by a thermostat or other control device when the ice formation is complete. The system is maintained in a stand-by condition until cooling of the vehicle is required at which time the shutters are moved to close the duct 5 and air passes in thermal contact with the ice in the tank. The current through the devices 1 may be reversed to heat the water in the tank and thereby the air passed into the vehicle. Fins 4a project into the air duct 5 and hollow heat exchange pins 6 define air flow passages 7. Power may be supplied by the vehicle battery or from an engine driven alternator or from an auxiliary power unit. Reference has been directed by the Comptroller to Specification 947,231.

Filed: 1952-03-11
Abstract: 714,730. Switches held set and freed mechanically; thermal switches. ROSNER. E. March 11, 1952 [April 3, 1951], No. 6338/52. Class 38(5) [Also in Group XXXVIII] A movable spring contact 1 is normally held away from a fixed contact 2 by a part'6 rotatable about an integral, parallel, spindle 5, the ends of parts 5, 6 being bent to form arms 3, 4, between which a rod 13 is movable. The rod 13 moves in a slot 14 in a fixed sleeve 12 and is fixed to a member 11 also movable in the sleeve and carrying a hook 17 pivoted at 16. Normally the tail 18 of the hook is arranged just within the sleeve 12 so as to prevent rotation of the hook under the tension of a thread or wire 20 which is attached to the hook. The remainder of the thread may be stretched across a door or window so that if an intruder engages it, the hook 17 and tod 11 are pulled upwards until the tail 18 clears the sleeve, so that the hook can rotate and release itself from the thread. The hook and rod 11 then drop under gravity and the rod 13 engages the arm 4 to disengage the member 6 from the contact 1 which thus engages contact 2 and completes an alarm circuit. If the thread breaks the hook and rod 1 1 drop down and operate the contacts in the same way. In a modification (not shown), the member 6 forms one contact so that the circuit is normally closed and is opened upon operation, the member 2 acting merely as a stop. The thread 20 may have sections of e.g. wax, so that the thread is broken in the event of fire or only a small increase of temperature.

As shown, the guide 24 is a trough of U-shaped section, through which travels an endless belt 10 running over rollers 11, 12 and a tension roller 13. The roller 11 is driven from a shaft 16 through bevel and sprocket gearing 17, 18, 22. The cigarette paper strip 25 travels over a guide roller 27 and a roller 26 driven from the shaft 16 through bevel and spur gearing 29-32. The paper strip 25 passes over the flat bottom of a channel 28 having side cheeks beneath which extend the edges of the strip. The loaded strip passes beneath a shaping roller 36, and through a guide 43 and a former 44, in which the strip travels on an endless band 45. The drive may be adjusted by a speed regulator so that the rod is delivered from the belt 10 to the strip 25 without change of speed. In a modification, the guide 24 is a U-shaped trough without a travelling belt.

Abstract: 716,958. Electric control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 17, 1952 [March 19, 1951], No. 6580/51. Class 40 (1). A liquid level indicator includes a variable electrical resistance, which comprises at least one electrical element 12 extending within, or as part of, an elongated hollow 11 which is adapted to be resiliently collapsed under the pressure of liquid into which it extends, the length of the element 12 which is electrically effective at any time depending on what proportion of the length of the body 11 is collapsed. The body 11 is insulating and may be of rubber or polythene, and the element 12 is a strip of resistive material, e.g. carbon-treated paper secured to the body wall. On collapsing of the body 11, the strip 12 is contacted in the collapsed part by a second strip 12 which may be resistive or conductive, e.g. copper. Various modifications are described. The strips 12 may serve to bridge two V-section body parts, thus forming part of the hollow body, or the strips 12 may both be conductive, a central rod carrying a resistance winding. Alternatively the winding may be dispensed with, the rod be conductive, and the strips 12 resistive. Again, the strips 12 may be replaced respectively by a stranded conductor 18 and by a zig-zag resistance 19 which is bowed transversely, see Fig. 8, or two stranded resistances may be each enclosed between two arms of a central conductive element of cruciform cross-section. A further embodiment differs from those previously described in that two conductive strips are not secured to the body wall, but are resiliently secured at their top ends, a central rod supporting a resistance helix. Finally, see Fig. 9, one electrical element 20 only may be used, comprising a resistance helix the coils of which are inclined to the horizontal to contact each other on collapse of the body. The body is preferably vented.

Title: Improvements relating to fuel systems for use with gas turbine engines
Inventor: CAREY FREDERICK HENRY
IPC: F02C7/22
Filed: 1955-03-07
Abstract: 797,360. Gas turbine plant. DOWTY FUEL SYSTEMS, Ltd. May 24,1956 [March 7, 1955], No. 6631/55. Class 110 (3). A gas turbine fuel system comprising a circulatory circuit which includes an enginedriven pump supplying a plurality of spill-type atomizers and a throttle valve in the return flow conduit between the atomizers and the inlet of the pump has in the circuit a first heat exchanger constituting a cooler for a fluid coolant such as engine oil and a second heat exchanger having a fuel cooling element disposed in an air passage, the flow of air through which cools the fuel under conditions of low fuel consumption. Fuel from a source (not shown) is fed through a filter 2 to the inlet of an engine-driven high pressure fuel pump 3 which discharges to spill type atomizers 5. The return flow pipes are connected in parallel with a return pipe 6 containing a servomotoroperated throttle valve 7. Fuel may return from the pipe 6 to the inlet pipe 1 in two ways. One way is through the heat exchanger 15 and control valve 18 and the other is through the branch pipe 32 and regulating valve 33. The valve 18 is a balanced valve and is actuated by a spring-loaded capsule responsive to the pressure in the chamber 27. The valve 33 is responsive to the pressure drop across the heat exchanger 15. During low altitude or ground level operation the flow in the return pipe 6 will be small so that the valve 18 will tend to be closed by the spring 30. At increasing altitude the return flow will increase. The pressure in chamber 27 will, as a consequence, rise and the valve 18 will be opened. Up to a predetermined flow in the pipe 6 and heat exchanger 15 the valve 33 will remain closed. At higher rates of return flow the valve 33 by-passes increasing quantities of fuel direct to the pipe 1. The element 16 of the heat exchanger 15 is cooled by air which may be boundary layer air bled from the wing roots. A further heat exchanger 37 is provided to cool a fluid coolant such as lubricating oil. Another heat exchanger 39 for cooling a further coolant may be provided. The fuel may be used to cool cabin air or used as a heat sink for compressed air when the cabin air is cooled on a compression refrigeration cycle.

Abstract: 398,197. Joints for artificial limbs. DESOUTTER BROS., Ltd., 73, Baker Street, and GROVES, H. H., Allerford, Queen's Walk, Kingsbury, both in London. March 5, 1932, No. 6693. [Class 81 (ii).] An artificial limb joint comprises a housing formed in one of the connected paits, a pivot member carried by the other part, and a bearing sleeve comprising at least two spaced apart portions which are accommodated within the housing and separated from one another on a plane containing the pivot member, and are provided with sockets each adapted partially to embrace the pivot member and held in contact therewith by spring means so that wear between the pivot member and bearing sleeve is automatically taken up. Figs. 3 and 4 show the application to the stirrup fitting of a leg. The stirrup 8 is pivoted to a waist-band in the usual manner and each limb of the stirrup is pivoted to the upper part of the leg bucket. A flange 19 on the bucket is formed with a projecting ball member 17 which is embraced by a flanged member of synthetic resin, hardwood, bearing or other metal for example phosphor bronze, or other material, bored eccentrically and formed to constitute a socket 16. This member is received by an aperture 13 and is cut to form two bearing parts 14, 15 bored at 20 to receive a compression spring 21. A cap 22, secured by a screw 25 entering an aperture 26 in the member 15 maintains the parts in position. The ball 17 is replaced by a pivot pin in the ankle joint construction, shown in Fig. 6, within a tubular member 27 is secured to the limb 28 and a pin 29 to the foot. A key member 33 prevents rotation of the bearing sleeve members 30, 31. In a modification, Fig. 7, a square aperture 34 accommodates bearing members 35, 36 which are forced to grip the pivot or ball member 37 by the action of a wedge 39 and spring 40. The gap between the bearing sleeve members may be double wedge shaped. The ball or pivot member may be flanged or otherwise formed to prevent axial movement. The means for retaining the bearing parts in position may comprise flanges acting in association with removable caps as described, or rings, plates, keyways, projections, screws or otherwise.
