Title: Dispensing mechanism for beverages
IPC: G07F13/06
Filed: 1962-07-16
Abstract: 997,913. Beverage making machines. C. TERRELL. Oct. 16, 1963 [July 16, 1962], No. 27293/62. Heading A4D. A mechanism for dispensing individually receptacles to be filled with a beverage has in combination a dispenser for cups as disclosed in Specification 970,090, a pump for dispensing a pre-determined quantity of beverage into an individual cup, an electric motor for operating the pump and push-button means for operating the motor by way of a relay associated with a switch arranged to operate the motor so that after operation of the button the motor operates automatically to initiate only one cycle of operation of the pump to dispense the predetermined quantity of beverage. The mechanism is housed in a casing which includes a thermostatically controlled tank 10 for hot water with a solenoid-operated water metering valve 11 which on the reception of an electrical impulse releases a predetermined quantity of hot water, four containers (not shown) containing respectively liquid coffee concentrate, liquid tea concentrate, milk and a liquid concentrate of sugar, a pump (not shown) associated with each container, refrigeration means (not shown) associated with all the containers and a cup dispenser as Specification 970,090. Each pump is connected to an electric motor by a common shaft 14 and a rock arm 15 and spring loaded connecting rod 16 which is connected to a rod 17 with arms 18, 19 of which shorter arm 19 slides in a guide 20 on which is mounted a horizontally movable blade 21 serving as an abutment to prevent downward movement of arm 19 and associated arm 18 which serves as a piston rod for the pump unless the blade 21 is retracted by a solenoid 23. Insertion of a coin, for example threepence, closes a microswitch in circuit with a relay to operate a motor to dispense a cup and operation of the push-button closes the solenoids controlling the pump for dispensing tea, sugar and milk which flow into the common channel for mixing with hot water and thence through a nozzle to the cup, a delay mechanism preventing operation until the cup has been dispensed. To obtain coffee a further coin, for example one penny, is inserted before operation of the button to energize through a switch the coffee pump instead of the tea pump. Other buttons may be provided to provide other combinations such as coffee alone, tea alone &c. The coin operated switches may be replaced by push-button controls.

Title: Thermostatic control system
IPC: F23N3/04
Filed: 1968-06-07
Abstract: 1,271,794. Valves. DRAYTON HYDROFLEX Ltd. 7 May, 1969 [7 June, 1968], No. 27311/68. Heading F2V. [Also in Divisions F4 and G1] A thermostatic control for a hot water boiler comprises a bellows 12 filled with a non-volatile liquid the bellows bing initially compressed so that subsequent expansion of the bellows only occurs if the liquid expands or if the control develops a leak. The bellows is connected by a passage 19 in an end fitting 13 and a capillary tube 20 to a sensing bulb 21 mounted in the water tank to be heated by the boiler. The bellows is initially compressed by being evacuated so that a screw 24 presses against a stop 13a of the fitting 13. The bellows, the capillary tube and the bulb are then fitted with liquid through a tube 32 which is subsequently sealed. An arm 25 pivoted on members 28 supports a shutter 27 and is secured to the bellows by a spring 31 and a nut 30. A control knob 18 is initially rotated to axially advance the fitting 13 to a position of maximum compression of the bellows and the bulb 21 is heated to 100‹ F. The nut 30 is then tightened to move the shutter away from the air inlet (not shown) of the boiler, the arm 25 in this position engaging a stop 33. Heating of the water tank by a further 16‹ F. causes sufficient expansion of the liquid to expand the bellows and thereby pivot the shutter to block the air inlet. Any further increase in temperature merely compresses the spring 31 thus lifting the nut 30 from the arm 25. The temperature at which the shutter closes the air inlet may be adjusted by rotating the knob 18 whilst a leakage in the thermostat allows atmospheric pressure to enter and expand the bellows thus automatically causing the shutter to close the air inlet.
Patent GB-758367-A (GB)
Title: Process and apparatus for coating elongated articles with multi-layer coatings
IPC: B29C48/09
Filed: 1953-10-06
Abstract: In a process for coating articles such as pipes with a multi-layer coating the coating materials are successively extruded in a direction perpendicular to the outer pipe surface, so as to obtain layers of uniform thickness on the pipe surface. In an apparatus for carrying out the process, a number of plates 1 to 7 surround a pipe to be coated and are secured by bolts 150. The coating material enters at A between plates 1 and 2 from an extrusion device to provide coating issuing from slots R and T. The material passes to an arcuate <PICT:0758367/III/1> <PICT:0758367/III/2> channel 10, between plates 1 and 2 ending in two vertical channels 103, 104, in the plate 2 which lead to two arcuate channels between the plates 2 and 3 each ending in two vertical channels in the plate 3.  These channels lead to four arcuate channels between the plates 3 and 4, each having an end, vertical channel in the plates 4 and 5, each with an end vertical channel in the plate 5 which in turn lead to sixteen channels between the plates 5 and 6 each of which feeds to two channels leading to the slot R opening on to the pipe surface. Similarly the second coating is applied from a slot T between plates 6 and 7.  Heating means 35 to 37 are provided to maintain the required temperature. The channels may be arranged in a horizontal instead of a vertical plane and the number of plates may be reduced to three for applying coatings to small pipes.  For larger pipes two such sets of plates may be superposed each set applying a coating. The pipe is moved lengthwise during coating, the rate determining the thickness of the coating.  By varying the rates of extrusion, coatings of different thicknesses may be applied.  The pipe may also be rotated to obtain helical stripes and the slots may be discontinuous to obtain stripes.  Protective coatings for joints may be obtained by placing a member of greater diameter on the tube then coating the tube and member and cutting off the coating of greater diameter after removing the member.  The outer coating may comprise a layer of polyvinyl chloride and the inner layer of polyethylene.  An innermost layer of tar may be applied.  The outer layer may be nylon. Specification 758,368 [Group XXVIII], is referred to.

Race games, mechanical.- An apparatus for playing a race game comprises a rotating disc, which distributes ba.lls or the like according to chance on to paddle wheels causing them to rotate and to draw along racing figures mounted on endless bands. In the form shown, the balls are dropped into a tube B rotated by a motor D and pass through holes b<1> on to a disc C which throws them by centrifugal action into a stationary cup E. The ball is thus fortuituously dropped upon a paddle wheel which is thereby caused to. rotate and to move a corresponding endless band H carrying a racing figure K. The ball runs out by a channel a<4> and may again be dropped into the tube B, the horses being caused to race along the track by repetitions of this operation. The horses are returned to the starting point by pulling, out a cord O attached to a sliding cross bar P which engages the carriages J of the horses. In a modification, the balls, instead of being supplied to the tube B by hand, are fed thereto from the channel a<3> by means of an elevating screw driven by the motor D. The racing figures may represent firemen climbing ladders, or motors climbing a hill.

Filed: 1954-10-01
Abstract: 752,768. Coating with metals; alloys. STANDARD TELEPHONES & CABLES, Ltd. Oct. 1, 1954 [Oct. 10, 1953], No. 28359/54. Classes 82(1) and 82(2). [Also in Group XXXVI] A method of manufacturing selenium rectifier plates comprises depositing (e.g. spraying) a cadmium alloy counter electrode on the selenium layer and then heat treating the plates at a temperature (e.g. 210‹-210‹C.) below the melting point of selenium (217‹C.). The invention is directed towards limiting the thickness of the reaction layer between the selenium and the counter electrode. The cadmium alloy used must have a melting point above 217 ‹C. and up to 266‹C. and the following per cent by weight compositions (with melting points) are quoted : (i) 22 /tin-62/cadmium-16/bismuth (220‹C.); (ii) 82À5/lead-17À5/cadmium (248‹C.); (iii) 17À4/zinc-82À6/cadmium (266‹C.); (ii) and (iii) are eutectic compositions. The conversion of the selenium into the conductive state may be effected using a two-stage heating process with the first stage at 130‹C., and followed by spraying on the counter electrode, and the second stage between 200‹ and 210‹C. which thus also accomplishes the reaction layer heat treatment required. If desired the selenium may be fully converted before the reaction layer heat treatment.

Abstract: 703,630. Protective cut-out arrangements. ANDERSON, A., and ANDERSON, BOYES & CO., Ltd. Dec. 24, 1951 [Nov. 23, 1950], No. 28645/50. Class 38(5) An earth-leakage protective arrangement for a polyphase line 7 ... 9 supplying a load 10 comprises a core-balanced transformer 1 having an auxiliary primary winding 2 which is energized to keep the line de-energized when the contactor 6 is opened on fault by current induced in the secondary 3 of transformer 1. The windings 2, 3, are, as shown, combined to form an autotransformer, the winding 3 being connected via rectifiers 4 to a coil 5 the contacts of which control a relay 5A whose contacts are in the circuit of contactor coil 6A. The primary 2 is connected on one side to the line 7 ... 9 over a multi-pole switch 14 which is ganged with contactor 6, so that when the latter opens, the switch 14 closes, and vice versa. The switch 14 may operate with a timelag. The other side of winding 2 is connected to earth through the secondary 12 of a transformer energized from the line side of contactor 6. An earth fault causes secondary 3 to energize relay 5 to open its contacts thereby de-energizing coils 5A and 6A, so that contactor 6 opens. The switch 14 closes simultaneously to energize winding 2 and maintain the energization of winding 3 so long as the fault persists. The Provisional Specification describes an alternative arrangement in which the winding 2 comprises two coils, of which the adjacent ends are joined to form one terminal and the remote ends are joined through half-wave rectifiers to form the other terminal. One terminal is connected directly to one phase of the line and the other to the secondary 12 through a single-pole switch ganged with the contactor.
