Abstract: 709,180. Refrigerating. STRAZNICKY, F. Dec. 2, 1952 [Dec. 7, 1951], No. 30537/52. Class 29 A refrigerator 12, Fig. 1, particularly for a vehicle, is combined with an internal-combustion engine, the liquid fuel passing from tank 24 to an upper chamber 7 from which it is absorbed by two spaced shells, 4, 5 surrounding the refrigerator and extending into the space 7, the liquid being evaporated to produce cold by air which enters through a valve 18 and passes through a pre-cooler 17 an outer air space 8, orifices 10 in the shell 5, and inner air space 9, the mixed vapour and air passing. through the pipe 19 of the pre-cooler to an injector 20 leading to the carburettor of the engine. Alternatively the arrangement may constitute the carburettor. For additional cooling, fuel may also flow through an expansion valve 27, pipe 26 and an evaporator 25 within the refrigerator which is connected by pipe 28 to the lower pressure created by the injector. Valves, 29, 30, which are ganged together, control the operation of the additional evaporator. As shown in Fig. 2, a container 104 having clips 194, 196 for bottles is supported by brackets 114 on pillars 112 carried by an outer casing 100. Secured to the bottom of the container are layers of fine metal mesh 148 which dip into fuel contained in troughs 124, 126, the side walls 122 of which are sealed to the container 104 by gaskets 134. Fuel is drawn up the mesh 148 by capillary attraction, this being aided and splashing being prevented by wicks 150. Fuel is supplied to the troughs through pipes 137, 130 from a chamber 110 in which a constant level 'is maintained by a float valve 140 controlling the flow from tank 108. A pressure equalizing conduit 147 extends between the chamber 110 and the evaporation chamber. Air enters the device through pre-oooling ducts 158 extending longitudinally through the evaporation chamber and then passes in contact with the mesh 148 in the upper space 156. The. mixed air and vapour then pass through apertures 166 to flow along the lower space 160 and through pipes 170, 174 to the carburettor 176. Grids 210 in pipe 170 prevent engine back-fire passing to the refrigerator. A valve 190 allows fuel to flow either from the fuel tank 184 to tank 108 or from tank 108 to the chamber 110. The refrigerator is supported on legs 198 and shock absorbers 200, 201 on the vehicle 205. For rapid initial refrigeration, a handactuated plunger can inject fuel directly from the tank 108 through a nozzle into the evaporation chamber. A throttle 204 in the engage intake controls the amount of refrigeration.

Convention date, April 12. Addition to 333,578, [Class 40 (iv)]. [Class 40 (iv).] Relates to an electrodynamic acoustic device, more particularly a transmitter, of the kind described in the parent Specification in which a diaphragm has a coil attached thereto suspended in an annular magnetic gap and a chamber having restricted openings is provided under the diaphragm, the chamber and openings being so dimensioned as to exert a damping effect on the movement of the diaphragm over a predetermined frequency range and is characterised in that the openings are overdimensioned and their proper degree of restriction is achieved by closing them with porous material, such as silk fabric. The transmitter shown comprises a magnetic casing 11 having a centre pole 12 and carrying an annular pole plate 14, all these parts being preferably made of hardened cobalt steel containing approximately 35 per cent cobalt. The pole 12 carries a block 16 of magnetic iron which is capped by a dome portion 17 of cobalt iron containing approximately 50 per cent cobalt. An annular insert 15 of this alloy is carried by the plate 14. A diaphragm 20 carrying the coil 27 comprises a central dome portion 21, an annular concentrically corrugated portion 22 and a rim portion 23 which is clamped between washers 24 to the insert 15 by the shallow mouthpiece 25. A plate member 37 of non-magnetic material, Fig. 6, has a collar portion 38 which embraces the block 16 whilst the slots 42 in the intermediate portion 41 thereof are covered by a fabric annulus 43 and arranged immediately beneath the air gap 18. The rim portion 40 of member 37 is secured to the insert 15, sealing means 44 being interposed to ensure that air flowing from or to the space under the diaphragm passes only through the slots 42 and fabric 43. In order to increase the response of the device at low frequencies, the space 46 at the rear of the diaphragm is connected with the front of the diaphragm by a tube 47 threaded at one end to engage the mouthpiece 25. The domed portion 17 of the central pole is also formed with a chamber 30 communicating through openings 31 with the space between the domed portion of the diaphragm and the member 17, the openings being covered with fabric 33. According to a modification of this arrangement (Fig. 4, not shown), the openings are formed in a separate plate held in a recess in the member 17 by the screw 29. The chamber 30, openings 31 and fabric 33 control the vibratory characteristics of the diaphragm over a band of frequencies between approximately 2000 and 5000 cycles per second whilst the chamber 32, air-gap 18 and fabric annulus 43 control the diaphragm over the entire frequency range. Specifications 382,668 and 388,069 are referred to.

Abstract: 1317098 Pulse radar SPERRY RAND CORP 30 June 1971 [6 July 1970] 30635/71 Heading H4D In an intensity modulated range/azimuth pulse radar display an echo signal above a predetermined threshold initiates a brilliance marker which is terminated by the output of a storage means which stores a selected portion of the range sweep waveform, the time period of the selected portion being determined by switch means itself controlled by the threshold means. The invention may produce a P.P.I. display as depicted in Fig. 3, to assist in ready assessment of possible collision. In one embodiment a switch means 124 is controlled by the output of threshold circuit 123 and by a circuit 130. The waveforms at points A to F are shown in Fig. 2; as regards waveform E, k is a time factor for collision warming (i.e. an intruder is regarded as a collision risk if (R/R)<k, where R is the range of the intruder) and w is the radar aerial scan rate in radians per second: if aerial 7 is afforded two available scan rates, tap 132 is set accordingly. Enlarged position "beads" on the incremental traces are effected by permitting blade 121 to remain closed against contact 121b and similarly for blade 141; enhancement of beads is made by changing over to contacts 121a, 141a. In the above embodiment the range sweep is logarithmic Fig. 2B; in an alternative arrangement a linear range sweep is utilized (see switch 13) and the trace increments will then be of variable lengths. In another embodiment an anti-collision criterion: is utilized, and a linear range sweep, Figs. 4, 5 (neither shown).  For slowly-changing closing ranges, the aerial rotation rate may be reduced or several aerial scans may be made with lead 140 only connected to grid 10, the present invention then be switched into circuit and so on. It is stated that the invention may be applied to an airborne type B display.
