IPC: H04B10/10
Abstract: 132,341. Case, T. W. Sept. 10, 1918. Lamp and flash signals; signalling proximity of vessels.-In signalling systems employing light radiations, the receiving-apparatus comprises a light-sensitive element placed in the circuits of a three-electrode vacuum or tube arranged to generate current of audible frequency, the incidence of the rays causing a variation in the resistance of the light-sehsitive element and consequently a variation in the frequency or pitch of the note heard in the receiving telephone. As shown in Fig. 1, the signal transmitter comprises a searchlight 14 fitted with a signalling shutter 17, or with a signalling-switch in circuit with the lamp. A screen 15 of smoked glass may cut out the visible rays transmitting only the infra-red. At the receiving-station, a selenium or like cell 9 placed at the focus of a reflector 19 is connected in the grid-filament circuit of a vacuum tube generator 1 in series with an adjustable portion of the battery 7. Between the grid 22 and plate 23 of the vacuum tube are connected a telephone receiver 4 and a battery 5. The filament 21 is heated by a battery 2. Normally a note is heard in the telephone and the signals alter the pitch of the note. Preferably the cell 9 is formed of a compound of thallium and sulphur which is particularly sensitive to infra-red rays. If ultraviolet rays are employed the cell is formed of a compound of thallium and iodine. The cell 9 may be supported by arms 1.1 nf gold or other metal in a case 10 closed by a glass cover 12. The system may be used for harbour defence by locating the transmitter on one side of the harbour in such position as to send the invisible beam across the inlet close to the water level, the passage of a ship or other object across the beam giving a signal in the receiving-apparatus located at the opposite side of the harbour.

Title: Improvements in or relating to metal hose clips
IPC: F16L21/00
Filed: 1943-08-17
Abstract: 573,695. Band clips. JAMIE, R. C. S., and HUNT & TURNER, Ltd. Aug. 17, 1943, No. 13395. [Class 44] A multiple band clip particularly for use on aircraft for making fluid-tight joints between adjacent ends of metal pipes joined by rubber hose-pipe reinforced by metal sheathing in sections, comprises two or more separate bands of metal strip, wire, or cable, located in parallel planes, each band having terminal loops the space between which is bridged by a curved strip, the loops receiving spindles or tubes having transverse holes to receive one or more tightening screws. The gap between the loops at the ends of each band is bridged by a curved strip. Fig. 1 shows two bands 1, 2 of transversely curved cross section except at the ends which are bent into loops 4, each secured by spot-weldings 5. One pair of adjacent loops receives a spindle or tube 6 having enlarged ends to retain the loops and a transverse threaded hole at 10, the other pair of loops receiving a similar spindle or tube 7 with a plain hole. The tightening screw 12 passed through the plain hole and engaged in the threaded hole 10 has its head 13 spaced from member 7 by a distance-piece having a conical surface 14 as described in Specification 573,698, and a cylindrical surface 15. A similarly shaped lock nut 21 is provided at the other end of the screw and the lock-nut may be finally secured by a split pin. Curved strips 9 bridge the gaps between the ends of the bands. The clearance between loop 4 and spindles 6, 7 allows the bands to rock slightly to bed themselves on the pipe and to facilitate this rocking the portion of the spindle within the loop may be spherical surfaced as at 27, Fig. 6. In place of the enlarged ends to the spindles, wire clips engaging annular grooves may be used to retain the bands so that if necessary they may be temporarily removed from the spindle to facilitate, for example, their application to a pipe in restricted space, Fig. 6 shows a clip having four bands in situ on a coupling-piece between two pipes 30, each spindle 28 having three transverse holes to receive corresponding tightening screws 29. The bands 23-26 are connected by transverse flexible strips 41 secured by spot welding 42 and preferably with corrugations 43 as described in Specification 573,697. When the bands are of wire, wire may be used in place of the strips 41.

Title: Method of and apparatus for refrigeration
IPC: F25D21/12
Filed: 1952-06-03
Abstract: 701,485. Refrigerating; drying air. WRETLIND, K. A. J. June 3, 1952 [May 31, 1951], No. 13950/52. Classes 29 and 34(1) In the cooling without frosting of a refrigerated space by circulating an absorbent liquid over a refrigerant evaporator and in contact with the air in the space, the liquid is reconcentrated by withdrawing a portion of it into an auxiliary vessel, heating this portion by means operated in response to the level of the removed portion in the auxiliary vessel and returing the dehydrated liquid to the circulating system. A water solution of glycerine, ethylene glycol or diethylene glycol is withdrawn from a reservoir 6 by a pump 7 which forces it through a chamber 5 where it is strongly cooled by an evaporator 2 and through a pipe 8 from the top of which it is sprayed by nozzles 11, 12 down a corrugated wall 13 and the pipe 8 to cool and absorb moisture from the air in a deep-freeze cabinet 10. Frosting up of the cabinet is thus prevented and the spray acts in a chamber defined by a wall 14 which is louvred to allow circulation of air. The diluted liquid flows back to the reservoir 6 by a pipe 9. When, due to dilution, the liquid level in the reservoir reaches level C, the pump 7 being idle, it syphons over through pipe 15 into a float chamber 16 until the level falls to A. Chamber 16 communicates by a pipe 18 with a boiler 17 electrically heated and provided with a rectifying column 21, condenser 22 and a condensate receiver 23. The re-concentrated liquid can flow back to reservoir 6 through pipe 19 in heat-exchange with chamber 16 and a solenoid operated valve 20. A motor 27 drives the refrigerant compressor 1 and the pump 7 and is controlled in response to the temperature in cabinet 10 by a thermal element 28. The operating coil of valve 20 is also controlled by this element so that the valve 20 can only be opened if the pump 7 is operating. When the chamber 16 and boiler 17 have been filled, the float 30 tilts mercury switch 25 to energize the heater 24 and to energize a coil which breaks a mercury switch 26 to prevent the valve 20 opening. When sufficient water has been boiled off, the float falls to stop heating and to allow valve 20 to open but this latter only occurs if the pump 7 is working and if the temperature in the boiler is high enough to close switch 29, which may alternatively be a mercury switch operated by a float.
