Title: Improvements in temperature control apparatus
IPC: G01K1/20
Filed: 1952-09-12
Abstract: 726,189. Automatic temperature control systems. MILWAUKEE GAS SPECIALTY CO. Sept. 12, 1952 [Sept. 13, 1951; May 22, 1952], No. 22986/52. Class 38 (4). [Also in Groups XXIX and XXXVII] In a thermostatically controlled, gas-fired water-heater, the electromagnetically operated control valves are energized from a thermocouple 68 heated by the pilot burner 15, Fig. 1 (not shown). An excess temperature trip is provided, and the thermocouple energization provides automatic flame failure protection. Gas supply circuit.-Gas entering passage 18, Fig. 2, passes normally open trip valve 122 (see below) to gas-cock 23 shown in the " on " position, having a transverse passage 24 leading to an electromagnetically-operated valve 56 controlling the supply to the main burner. An axial bore 25 in the gas-cock leads to a passage 26 supplying the pilot valve, Fig. 4. In the pilot-only position of the gas-cock, a half transverse bore 28, is open to the supply. The trip valve 122 is set open by a push-rod 128, Fig. 3, and held open against spring bias by an electromagnet 106 when the thermocouple is heated by the pilot burner. The resetting push-rod 128 is interlocked by an arm 131 and register pin 134 co-operating with a bore in the gas-cock handle, Fig. 3 (not shown), whereby it can only be operated in the " pilot " position of the cock. Electric control circuits.-Excess water temperature operates a bimetallic snap disc switch 82 to de-energize the lock-out valve holding magnet 106. Thermostatic control is effected by a liquid-filled bellows type temperaturesensitive element housing contacts immersed in the liquid filling and connected in the magnet circuit of the control valve 55. Owing to the low thermocouple voltage the control may be effected by variations in contact resistance without actually opening the contacts.

Filed: 1973-05-15
Abstract: 1426586 Electroless deposition of metal patterns WESTERN ELECTRIC CO Inc 15 May 1973 [15 May 1972 (2)] 23031/73 Heading C7F  Metal patterns are electrolessly deposited on substrates by contacting the substrate with a photo-sensitive colloidal sensitizer solution comprising an insoluble colloidal hydrous oxide of Pd, Pt or Au, selectively exposing parts of the sensitized surface to ultraviolet radiation to form a pattern and then contacting the surface with an electroless metal solution to deposit metal only on those parts not exposed to the ultraviolet radiation. The colloidal sensitizer solution may be prepared by a hydrolysis and nucleation reaction in which an aqueous solution of a Pt, Pd or Au salt has its pH maintained at a value such that no precipitate or flocculate occurs. The colloidal solution preferably contains particles 10-10,000 A‹ size and the ultraviolet radiation wavelength is less than 3000A‹. The metal deposited from the electroless solution may be Cu, Au or Pt and the solution may contain formaldehyde as a reducing agent. The substrate may be non-conductive e.g. a polyimide resin and a positive quartz mask may be used to mask the sensitized surface. The process is used in producing printed circuits.

Title: Anodes for the Electrolytic Production of Aluminium and Aluminium Alloys
IPC: C25C3/12
Filed: 1967-05-19
Abstract: 1,177,829. Producing aluminium by fused electrolyte process. COMALCO ALUMINIUM (BAY BELL) Ltd. and UNIVERSITY OF TASMANIA. May 19, 1967 [May 23, 1966], No.23414/67. Heading C7B. [Also in Division C1]  A mixture for the manufacture of an amount for an electrolytic cell for producing aluminium or its alloys comprises a mixture of carbonaceous material consisting of (1) Coal Tar Pitch or Oil Tar Pitch in an amount of 12-35% by weight of the carbonaceous material. (2) 88-65% by weight of calcined petroleum coke in combination with 0À5-25% (by weight, based on the total weight of mixture) of a compound selected from the oxides, carbonates and fluorides of Li, Na, K, Ca, Al and Be, or a compound of the above metals that will decompose at or below 1200‹C. to give one of the compounds mentioned. Preferred additives are A1 2 0 3 , CaF 2 , Li 2 CO 3 , CaCO 3 , LiF, Na 2 CO 3  and Cryolite. In making a pre-baked anode preferably 12-16 wt. % of Pitch and 88-84 wt. % of Coke are used in the carbonaceous material, while for a self-baking (Soderberg) anode 30-35 wt. % of Pitch and 70-65 wt.% of Coke are preferably used. A method of making the mixture comprises adding the additive compound to the calcined petroleum coke, and subsequently adding the Pitch; the anodes may then be made by baking before or as the mixture is fed to the electrolysis cell. Improved electrode life and performance are obtained with the anodes when used in electrolysis cells such as the Hall-Heroult cell. The consumption of the electrode during electrolysis results in passage of additive into the electrolyte; thus some of the metal is incorporated in the product.

Title: Improvements in Heat Exchangers for use in Freeze-Drying and The Like
IPC: F26B5/06
Filed: 1966-05-26
Abstract: 1,153,283. Heat exchangers; freeze drying units. W. G. G. CUDDON Ltd. 26 May, 1966 [3 June, 1965], No. 23504/66. Headings F4G and F4S. A combined baffle and heat exchange element intended for location between the hot and cold coils of a freeze-drying unit, comprises a plurality of parallel, spaced apart, V-shaped zigzaging or arcuate plates E each of which has, in thermal contact therewith, two sets of U-shaped pipes G and L. In use the baffle is constructed and arranged within the freeze-drying unit so that:- (a) the pipes L are nearest to the cold coils and the pipes G nearest to the hot coils. (b) passage of radiant heat between the two coils is obstructed and hot vapour, passing from the hot to the cold coils, can not take a straight line path between said coils but is forced to follow the contours of the baffle plates. (c) a mixture of hot liquid and gaseous refrigerant discharged from the ice coils passes from the outermost to the innermost pipe L, the latter being adjacent pipe G, and in doing so is heated by both the hot vapour and by the plates themselves as a result of which, the liquid component is gasified before the refrigerant enters a compressor for re-cycling. (d) hot liquid refrigerant, from a receiver supplied by the compressor, is passed from the outermost to the innermost pipe 6 and in doing so gives up some of its heat to the plates E, and hence pipes L, before entering an expansion valve located between the receiver and ice coils. The hot coils are supplied with heat from the compressor exhaust. The plates may be flat with the pipes thermally attached thereto and may be formed into any suitable shape which would prevent a direct passage of vapour between the two coils. In an alternative embodiment the innermost pipes G and L may be interchanged. Both the two coils and the baffle are located in an air-tight cabinet from which air may be exhausted.

Abstract: 1,019,599. Electric bells. STANDARD TELEPHONES & CABLES Ltd. June 8, 1964, No. 23592/64. Heading G5J. In a polarized magnetic ringer having a volume control, a rotatable control wheel 13, comprising variable motion-limiting means, is mounted under the arm of the hammer 12 with its axis parallel to the plane of motion thereof. As described, the control wheel has projecting flanges which form a channel of variable width around its circumference which determines the extent of travel of the arm of the hammer. In a modification, Fig. 5 (not shown) the control wheel is formed as an eccentric having damping material around its circumference. The ringer has a single coil 1 containing a soft iron core 3 and a ferrite polarizing magnet 2, which magnetizes both projecting ends 11, 11 of the core in the same sense. A U-shaped armature 4 is pivoted on captive bearing balls 5, 6 and is retained by a wire spring 9, which passes through a hole in it and a slot in a platform 7 projecting from a base-plate. The spring is retained in a recess at the back of the platform, formed at 90 degrees to the slot, Fig. 4 (not shown). The armature ends 10, 10 and the co-operating core ends 11, 11 are bent so that the magnetic forces between them are at rightangles to lines projected from the gaps to the pivotal axis of the armature. Adjustment of the air gaps is provided for by slots 15 in the sides of the coil cheeks, through which fixing screws 14 pass. In a modification, Fig. 6 (not shown), a composite moulding is used for mounting the movement and the volume control.

Filed: 1973-05-17
Abstract: 1437473 Remote control of TV receiver THORN ELECTRICAL INDUSTRIES Ltd 2 May 1974 [17 May 1973] 23639/73 Heading H3Q A television receiver has a digital counter 20, 22, 24 arranged to be controlled by control signals and arranged to retain a control valve until a further control signal is obtained and a rechargeable battery 32 for supplying the counter 20, 22, 24. Control signals are received by an ultrasonic receiver and decoder 10 to provide up-down control of bi-directional counters 20, 22, 24 whose outputs are fed via digital/analogue converters 26, 28, 30 to control sound volume, and picture brilliance and colour saturation of the TV receiver A rechargeable battery 32 supplies the counters 20, 22, 24 so as to store their count when the receiver power supply is switched off. The draw on the battery 32 can be so small that the battery will last for several months without recharging. When the receiver is switched on the battery 32 is recharged from a rectifier circuit 38 via a diode 34 which prevents discharge through the power supply when the set is switched off. Preferably if the battery 32 fails or becomes disconnected the values set in the counters will be preset to a predetermined normal value being powered directly from the source 38. The receiver can be provided with touch-type controls on its facia. When the wire-less control link is not used the settings can be altered by these touch-type controls which are connected to the inputs of the counters in parallel with the output of the receiver 10. The touch controls can be resistive touch pads with appropriate impedance transformation circuits or in the form of light-pressure switch contacts which connect a potential to the appropriate counter input. The receiver may be adjustable by such touch-type controls alone, the microphone 12 and receiver 10 being omitted.

Filed: 1927-09-08
Abstract: 277,351. Adrema Maschinenbauges. Sept. 8, 1926, [Convention date]. Addressing-machines; tripping-arrangements. -Relates to addressing - machines of the type in which address-plates are advanced in procession along a lateral guideway 6 to printing position beneath a platen 5 carried by a pivoted arm 3 oscillated by means of a handle 10 and in which a skipping-lever 14 is provided for skipping address-plates from which no impression is required and in which, also, mechanism is provided for intermittently advancing a strip 41 on which a list is to be printed. A system of levers is interposed between the lever 14 and the list-feeding devices, whereby the feed may be interrupted when the lever 14 is turned into the operative position. The strip 41 is clamped at its forward end to a plate 24 slidable in guides 23 and is fed forward by means of a rack 25, which is reciprocated by a toothed sector 26 and engages a pawl 27 on the plate 24, the sector 26 being oscillated by a rod 32 connected to the arm 3 by a pin 36 normally engaging the vertical branch of a bayonet-slot 34 in the rod. When an address-plate to be skipped arrives in the printing position, the operator presses a knob 19 on the end of a rod 16 slidably mounted on the arm 3 and thereby rocks the lever 14 about its pivot 12 so that a buffer 15, by striking the machine table 2 prevents the full descent of the platen 5. The lever 14 is connected by a rod 40 and a pivoted plate 39 to a rod 37 engaging the rod 32, whereby the latter is raised so that the pin 36 is in line with the horizontal part of the slot 34 and, at the next upward movement of the arm 3, instead of the sector 26 being actuated to feed the list forward, the pin 36 simply rides along the slot.

Abstract: 1,015,212. Angular bending; stretching. CYRIL BATH CO. June 20, 1962, No. 23678/62. Heading B3E. [Also in Division G1] A load cell for use in stretch forming machines comprises two rigid elongated arm members 40, 55 which are in telescopic relation to one another, but are spaced apart and connected together so as to allow relative movement therebetween lengthwise of the members, the connection being in the form of a plurality of stiff elongated elements, e.g. bolts arranged transverse to the arm members at spaced portions along the overlapping portions of the arm members, and connected at opposite ends to one of the members 40, 55, respectively, each element being capable of flexing to allow telescopic movement of the arm members, and an elastically deformable tension element between the two arm members which is deformed lengthwise by the telescopic movement of the arm members and a device to produce a signal in response to elastic deformation of the tension element. The stretch forming machine, Figs. 1, 2, comprises a frame 1 with a turntable 2 which is driven through a ring gear 4 from a pair of hydraulic motors to which pressure fluid is supplied from a variable delivery pump 9 to accurately control the speed of the turntable. A stretch forming piston and cylinder assemblage 12 is mounted on the frame 1 and comprises a reciprocable carriage 13 driven by a doubleended piston 14 having rods 15, 16 secured to the frame 1 at 18, 19, respectively, and working in a cylinder 17. The cylinder 17 is secured to the carriage 13 in such a way as to allow slight rocking movements between the two to allow for any misalignment and by supply of pressure fluid from an hydraulic pump 30 and a motor 31 to one side or other of the piston 14 in the cylinder 17 the carriage 13 may be reciprocated. The carriage 13 is retained in guides 25, 26 by rollers 27, 28, 45 which are arranged to prevent removal of the carriage from the guides during operation of the machine. The carriage 13 is provided with a vertical post 41 on which swings an arm 40 supported in slide pads 42, 43 and carrying a stretch forming head 46. The arm 40 incorporates a load cell according to the invention (see Division G1) and to form a stock 5 it is clamped between the head 46 and a clamp 47 on the turntable 2 and is formed by a die D. The load cell controls the pressure of fluid supplied to the cylinder 17 to keep it within desired limits during operation of the machine. Because of its length the cylinder 17 is supported at its ends by rollers 33, 35 running on guide rings suitably arranged in the frame 1.
