Title: Improvements in and relating to air conditioning systems
IPC: F24F3/14
Filed: 1938-12-09
Abstract: 522,581. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 9, 1938, No. 35986. Convention date, Dec. 9, 1937. [Class 38 (iv)] [Also in Group XIII] Temperature ; humidity.-An air conditioning system for an enclosure comprises an air duct 10 with circulating means 14 and two refrigerant evaporators 15, 16, preferably in sequence, in the duct, the pressure in one being maintained above that in the other, and flow control means for each operating respectively in dependence on the temperature and relative humidity of the air in the enclosure. The evaporator coils 15, 16 receive liquid from a line 18 through normally closed solenbid valves 29, 30. Thermostatic expansion valves 25, 26 ensure that the quantity of liquid admitted to each evaporator depends upon the saturated refrigerant pressure in the evaporator and the superheat temperature of the vapour leaving the evaporator. Suction pressure control valves 33, 34 of the same construction but differently adjusted determine the pressure in each evaporator, so that evaporator 15 is maintained normally above the dew-point temperature of the air while evaporator 16 is maintained below it. The system is controlled by a thermostat 47 and a humidostat 57 which respectively control electric relays 48, 59. On a demand for cooling a winding 51 is energized and the relay 48 energizes the coil 56 to open the valve 29 and a relay 52 to start the compressor motor 20; when the enclosure temperature has fallen the thermostat 47 will short circuit the'relay and the valve 29 will close; at the minimum permissible temperature a thermostat 53 will short circuit a normally closed relay 54 to stop the operation of the system. Should the relative humidity in the enclosure be too great the humidostat 57 will energize winding 58 and relay 59 will energize coil 60 to open the valve 30 and relay 52 to start the compressor motor 20; at the lower limit of relative humidity the winding 58 is short circuited and this valve 30 will close. The pressure control valves 33, 34 comprise a valve 38, Fig. 2, opened against the pressure of a spring 43 by a bellows 40 the interior of which is in communication with the vapour issuing from the evaporator; the spring 43 is confined between one end of the bellows and an adjustable collar 44 screwed into a casing 41. In a modified system (Fig. 3, not shown) the pressure of these springs is adjusted in accordance with the temperature and relative humidity of the air in the enclosure so as to reduce the time required by the system to meet relatively great changes. Each valve comprises a cam 95, Fig. 4, operated by a rack 98 which is subject to the opposed influences of a spring 97 and a solenoid 96, and the energization of each solenoid is varied by potentiometer contacts controlled respectively by a thermostat and a humidostat responsive to air conditions in the enclosure. The compressor motor is controlled by a relay and thermostat such as 53 in Fig. 1.

Title: Improvements in and relating to high frequency tuning coils
IPC: H01F17/04
Filed: 1935-12-30
Abstract: 452,188. Electric inductances. MICHAELIS, E., 14, Talbot Square, Hyde Park, London. Dec. 30, 1935, No. 36005. Convention date, Dec. 28, 1934. [Class 37] In a high-frequency tuning-coil, for use in coupled circuits and having an internal core of compressed iron powder and two annular cores or an annular and a disc-shaped core of the same material, and in which the inductance of the coil is adjusted by varying the gap between the inner core and one of the annular cores or the disc-shaped core, a separate support for the adjustment means and for the coupling coil is dispensed with by providing an extension on the tuning coil support or on the internal core which serves to carry the coupling coil, while the adjustment means is in screw-threaded engagement with a further extension on the coil support. In the form shown, the tuning coil support a is provided with an extended flange 1 which is used for attaching the device to a supporting plate and is provided with an internal core c and with annular masses b<1>, b<11> all of compressed iron, the latter being attached to the support a. The support is provided with an extension a<1> on which the coupling coil d is supported and with a further extension all, which is screw-threaded to co-operate with a screw of artificial resin or metal attached to the core c. In a modification, the adjustment means is in the form of an iron disc carried by a screw-threaded support of artificial resin which engages in a tubular extension on the end flange of the coil support a, while in a further construction, this form of adjustment device is employed, but the internal iron core itself extends beyond the flanged end of the support a and forms the extension on which the coil d is mounted.

Title: Improvements in or relating to methods of producing purified silicon
IPC: C30B25/02
Filed: 1958-11-11
Abstract: A silicon halide, e.g. trichlorosilane, containing a boron halide is treated with propionitrile, p-hydroxyazobenzene, or benzene-azo-a -naphthol, and distilled off from the resulting boron complex.  The degree of boron removal may be such that silicon produced from the silicon compound contains not more than 1 boron atom per 106, 1011, or 1013 silicon atoms.  The silicon may be deposited on a carrier consisting of a rod of pure silicon by a thermal or electro-thermal reaction, optionally in the presence of hydrogen.  The resulting rod may be reduced in thickness by drawing and then re-used as carrier. The resulting rod may for example be zone refined to such an extent that at least 50% of the rod is p-conductive and that any point in said p-conductive portion varies from the average resistivity of the portion by less than 5, 10 or 20%.  A low pressure may be maintained during zone refining.  The walls of the zone refining vessel may be cooled so as to condense vaporized impurities thereon.  An electromagnetic field may be used to support or agitate the molten zone.  Specification 809,250 is referred to.

Title: Electric fuse switch
IPC: H01H31/12
Filed: 1957-11-26
Abstract: 875,258. Snap-action switches. VERHULST, R. Nov. 26, 1957 [Jan. 22, 1957; April 15, 1957], No. 36788/57. Class 38 (5). A snap-action fuse-switch comprises a stationary insulating part 1 with a double set of spring clip contacts 3 in each pole, a sliding part 32 mounted on guide rods 38 and carrying contact knives 55 with respective interconnecting fuses 56, and an actuating mechanism with handle 12 to operate cranks 13, 14 and 15, 16 for closing and opening the switch by compressing springs inside sleeves 26. The rods 38 are secured to the moving part 32 and slide in bushings 35, 36 screwed into the base part 1 (Fig. 4). Each rod 38 has two grooves 39, 40 suitably spaced to co-operate with spring-loaded balls in the bushing 36 and lock the switch in its closed and open positions respectively. Rubber rings 43 and 48 act as shock-absorbers. Fig. 5 shows one crank (15, 16) and associated actuating mechanism in its condition just prior to closure of the switch. Connecting rod 22, slidable in a pivoted member 20, is compressing spring 28 against the end 29 of sleeve 26 which is anchored at its other end in the moving part 32 of the switch by means of a rubber insert 31. When the locking force of the balls acting on the rod 38 is overcome the switch suddenly closes. On reverse movement of the handle 12 the crank causes member 20 to slide along rod 22 and engage a tube 25 fitted loosely on the rod 22 but having a ring 27 which compresses spring 28, tending to cause opening of the switch, which occurs when the locking action of the balls on rod 38 is again overcome. In a modification (Figs. 12 and 13, not shown), the operating handle 12 is pivoted in the vicinity of the moving part 32 on a bracket extending from the side of the fixed part 1, and operates the cranks by means of a connecting rod.

Abstract: 333,841. Trescartes, L. Dec. 20, 1928, [Convention date]. Vibration-dampers.-Vehicle shock-absorbers of the radially expanding type are provided with braking elements consisting of a waved or undulated steel spring embedded in rubber which is faced with frictional material, the elements being adapted to be expanded or compressed by the driver to vary the damping effect. In the construction shown in Fig. 4 two braking elements are expanded radially into contact with the drum 3 by cams 20 mounted on a central spindle which is operated by a link or wire connection to the lever 21. Each of the braking elements consists of an undulating steel spring 13 embedded in a block of rubber the outside of which is faced with frictional material 12 while the inside is fitted with a fibre or similar hard block 18 which is engaged by the cam 20. One end of each braking element is secured to a metal block 10, 11 clamped rigidly by the bolts 8, 9 between two cover plates connected to the arm 3a, the drum 3 being connected to the other arm. Relative movement of the two arms thus moves the drum 3 relatively to the braking elements carried by the cover-plates. The lever 21 which adjusts the cam 20 may be connected to a wire 24 the other end of which is coiled round a drum 26 operated by worm gearing from a flexible shaft enclosed in a tubular casing 28 as shown in Fig. 3. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the construction shown in Fig. 9 (Cancelled) in which the braking elements each consist of an undulated disc 32 embedded in rubber which is faced on both sides with friction discs 33, 34. Two of these elements are interposed between inner discs connected to one operating arm. Pressure is applied to the assembly by spring discs 31 and by a central pin the ends of which are formed with right and lefthanded threads. The pin is rotated to vary the pressure by arms 35, 36 connected by Bowden wires or other wire to a control within reach of the driver. This subject-matter does not appear in the Specification as accepted.
