Title: Improvements in or relating to dispensing machines for ice cream
IPC: G07F9/10
Filed: 1961-07-20
Abstract: 911,724. Coin-freed vending apparatus. DUPLIC INDUSTRIES. July 20, 1961 [July 21, 1960], No. 26262/61. Class 27. [Also in Groups II and XXX] A coin-freed ice-cream dispenser comprises a pair of rotary containers 35, 36 for stacks of cones, a rotary whipping device 122 controlled to maintain a predetermined viscosity of the ice cream and a timed valve 138 for delivering a measured quantity of ice cream to a cone delivered to a dispensing position 30. Each cone container comprises a number of tubes 38 supported by plates 40, 42 and indexed by a solenoid 96, spring-loaded ratchet plate 100 and wheel 108 to bring the tubes sequentially over an aperture 48 in a fixed plate 46 ; correct alignment is ensured by a pawl 110 and notches 114. The cones from a tube fall to a lower pair of fingers 60 which grip a lower lip of the cone and when a cycle of operations is initiated by inserting a coin in a box 32 a solenoid 82 is energized to cause pins 80, 78 to open the lower fingers 60 for release of the cone and to allow closure of upper fingers 58 below an upper lip of the succeeding cone. When a tube is exhausted, a switch 94 detects the absence of cones and energizes the solenoid 96 to index round the next tube. The released cone slides down wires 28 to a position 86 and past a gate 84 which is turned to a position 92 by a solenoid 88 when a container is entirely emptied and a dog 120 operates a switch 118 to transfer power to the other container 36; a similar switch turns the entire unit off when the second container is emptied. Ice-cream material is fed from a pan 24 into the cylinder 122 and is increased in viscosity by the action of a freezing coil 123, whipping blades 130, 132 and a straight wiping blade. Indentations in a forward blade plate feed the ice cream to the dispensing nozzle 136 and solenoid-controlled valve 138. A motor 18 drives the whipping device and is mounted on a trunnion so that, as the torque reaction increases with increasing viscosity of the ice cream, the mounting tilts and operates a switch to stop the motor. The motor is energized at regular intervals by a timing relay and upon each coin insertion. Other timing relays control the sequence of operations and the period of opening of the valve 138.

Title: Improvements in or relating to thermostatic regulating valves
IPC: G05D23/12
Filed: 1939-09-21
Abstract: 534,978. Valves: fluid-pressure servomotors. SHERLOCK, J. E.. and BRITISH THERMOSTAT CO., Ltd. Sept. 21, 1939, No. 26351. [Class 135] A thermostatic regulating valve for controlling heating or cooling systems of the kind in which a regulating valve is operated by the thermal expansion of a fluid contained in a flexible metal bellows, or similar expansible chamber, is constructed so that in the event of a leakage in the bellows the valve is moved to cause a cooling system to operate at the full, or to cut off the source of heat in the case of a heating system. As applied to a cooling system for an internal combustion chamber in which when the engine is cold the cooling liquid flows from a pipe 5 to a pipe 7 which byepasses the radiator, the control valve 15' throttles the flow of fluid in a circuit containing a reservoir 1, pump 2, and a bellows 3. The pressure in the bellows 3 thus acts against a spring 8 to maintain a valve 4 in a position which directs the cooling fluid to the pipe 7. When a phial 13, filled with liquid is heated by the engine. a bellows 12 raises the valve 15, and liquid flows through the valve via pipe 17 and port 15a, thus relieving pressure in bellows 3 and permitting spring 8 to cause the valve 4 to direct the cooling liquid through the radiator. In the event of leakage in the bellows 12, a spring 14 depresses the valve 15 to such a position that the throttle valve is moved downwards past its closed position to a position in which the opening 15a registers with pipe 18 thus causing the valve 4 to move to the position in which the passage to the radiator is open fully. In a modification Fig. 2, the phial 27 connects by pipes 26, 28 to two bellows 25, 29 acted upon by springs 30, 31, of which the spring 30 has a stronger action than the spring 31. Valves 24, 23 are operated by the bellows, and the valve 24 normally opens, when the fluid in the phial 27 attains a given temperature, to permit the supply of cooling fluid from a pipe 20 to a pipe 21 leading to the radiator, or the like. Or the valve may control the supply of fluid to a throttle device as in Fig. 1. If either of the chambers 25, 29 leaks the valve 24 closes but the valve 23 opens and maintains the supply of cooling fluid. In a further modification involving the use of two metal bellows, the movements of these control a lever member which operates a lift valve controlling the flow of a cooling fluid. The action of this modification is somewhat similar to that of Fig. 2 in that springs of unequal. strength determine the actions of the bellows on the lever, and also in that the cooling action is caused to operate at full efficiency in the event of a leakage in either of the bellows.

Title: Improvements in or relating to trench mortars or the like
IPC: F41B11/00
Filed: 1939-09-26
Abstract: 586,629. Pneumatic guns. HOLMAN BROS., Ltd., and HOLMAN, A.'T. Sept. 26, 1939, Nos. 26676/39, 409/40 and 12788/40. [Class 92 (ii)] A pneumatic gun, particularly one of trench mortar type, has valve means for admitting compressed air to the gun barrel behind a projectile and a device actuated by the projectile on reaching its firing, position for permitting or effecting operation of the valve means for discharging the projectile. The invention is shown applied to a trench mortar of the Stokes' type in which discharge is effected by the base impact of a projectile sliding down the barrel 3. Air under pressure for discharge passes from reservoir 10 through ports 14 past the seat 12 of a valve 11 which tends to open under pressure acting on steps 48, 49. The chamber 23 below the valve is under pressure from a previous discharge through passages 50, 52 uncovered by the valve, and this pressure is relieved at the moment of discharge by acting through a cam-operated trigger-rod 34 on an atmospheric relief-valve 30. A pivoted distance-piece 46 on a lever 45 on a rod 16, which is moved transversely by the pressure of the projectile on a trip lever 41, prevents action of the rod 34 on the valve 30 except when the projectile is in discharge position resting on the rod 16. The trigger-rod is operated by a cam 37 on a rotatable hand-grip 36. A projection 53 on the lever 45 permits direct operation of the valve 30 if the projectile siezes in the barrel or for practice purposes without using a projectile.

Filed: 1973-06-05
Abstract: 1433942 Waste-winding SOC DE LA VISCOSE SUISSE and MASCHINENFABRIK RIETER AG 5 June 1973 [9 June 1972] 26683/ 73 Heading D1J A winding machine with a self-threading traverse guide 4, Fig. 3 has an auxiliary guide 7 Fig. 2 for guiding the filaments in a wastewinding zone 6 of the package support 1, the guide 7 being on a guide bar that extends substantially parallel to the axis of rotation of the paokage support, the guide bar 9 being axially displaceable and, in addition, rotatable about is axis or movable transversely thereof, there being means for catching the filament near the completion of the package winding operation and for removing the filament from the traverse guide 4. At the start of a winding operation the filament 2 is attached to the former 1. The guide 7 is swung about the axis 9 into a horizontal setting, Fig. 4. The filament initially runs against the edge 8. Whilst the former 1 speeds up the filament 2 slides over the guide edge 8 and is wound into a narrow waste collar 6, Fig. 2, at the outer edge of the package support 1. After full speed has been reached, the guide 7 is pivoted upwardly to a setting permitting the filament 2 to slide along the guide edge 8' and so cause the filament to form a reserve winding 6'. The speed at which the auxiliary guide 7 is pivoted is governed by the required number of reserve windings and can be adjusted accordingly. The filament 2 then slides along the edge 10 into the range of the self-threading filament guide 4 to form the cross-wound package 5. After the cross-wound package has 'been formed the guide 7 is swung back into the starting position shown in Fig. 4 to cause the filament 2 to be caught by the two edges 10 and 11 of the guide 7 to lift it out of the guide 4. A waste winding 12 is then formed on the package 5 by sliding the guide rod 9 with the guide 7 thereon back and forth. In a modified construction, Fig. 6 (not shown) the guide 7 does not rock about the axis 9 but is moved away from the package by piston and cylinder mechanisms. In a further modified construction, Fig. 7 (not shown) the guide 7 is not planar but is curved in the direction of filament travel. Between the guide rod 9 and the guide 7 is a slipping clutch enabling the guide 7 to be manually adjusted during the operation of the mechanism.

Filed: 1925-10-26
Abstract: 245,418. Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij, and Maser, F. R. Jan. 2,1925, [Convention date]. Dust-laying compositions.-Asphalt, bitumen, &c. is emulsified in a known manner, and is then coagulated in the presence. of finely-divided substances of the colloidal order to form a fine mud which resists further coagulation. The " asphalt gel " thus produced may be added to solutions of magnesium chloride or sulphite lye to make a dust-laying composition, or it may be mixed with cement paste, lime paste or paper paste, or with slag. stone, and like granulated substances. The precipitation from the emulsion is obtained by stirring in an electrolyte, in presence of the finely-divided substances such as aluminium hydroxide, ferrous hydroxide, clay, humus, barium sulphate, magnesia, silica, calcium carbonate, or by the presence of the finely-divided substances alone. According to an example, 1000 kg. of petroleum asphalt are emulsified in such a way that the emulsion contains 50 per cent of water. 5 kg. of caustic soda are added. and the emulsion is stirred into a. solution of 5 kg. of aluminium chloride in 1,000 litres of water.

An induction motor 1 is braked by connecting its stator winding through switch 3 to a directcurrent exciter 4, the motor rotor winding being connected to a load resistor 2. The ratio between the field current of the exciter 4 and the load current is maintained substantially constant by means of a balancing relay 10 having opposed windings 9, 11. The winding 11 is energized in accordance with the load current by means of current transformer 13 and rectifier 12. The winding 9 is connected across a resistor 8 which is placed, in series with the exciter field winding 7, across the armature of a pilot exciter 5. If the ratio between the load and field currents departs from a given value, the relay 10 is moved to energize a reversible control motor 14 and adjust resistor 15 in the field circuit of the pilot exciter in such manner that the ratio is restored to its pre-determined value. Currents proportional to the load current and to the exciter field current may be combined in opposition and the resultant signal applied to electronic apparatus or a voltage regulator controlling the field current of the exciter or of the pilot exciter.

Abstract: 714,667. Digital electric calcutating-apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 27, 1952 [Oct: 30, 1951], No. 26932/52. Class 106 (1). [Also in Group XXXIX] A circuit-arrangement, e.g. in an automatic telephone system or electric calculating machine, for receiving and storing numbers represented by! at least two series of pulses includes an electronic; counter TS comprising gas-filled tubes B10-B19 which are ignited in succession by the pulses, the ignited tube extinguishing when a next following tube ignites, and at least one electronic register RG1 comprising gas-filled tubes B20-B29 each associated with a different tube of TS and having, an ignition electrode f connected through an integrating network such a R30-C21, to a point on a resistor, such as R10, connected to the cathode of the associated counter tube each of these points being so arranged that when this counter tube is conducting, the potential difference between this point and the cathode of the associated register tube is higher than the ignition voltage if none of the register tubes is conducting but is lower otherwise, means being provided to extinguish the tubes of TS when a tube of RG1 ignites. As shown, the counter TS is of known type,posi-  tive input pulses being applied to conductor I and through capacitors C0,C1 &c. to the ignition electrodes f of All the tubes B10, being so biased as to be ignited first. Each tube B11-B19, when ignited; extinguishes the previous tube through a cathode coupling capacitor C11, C12 &c. Three pulse series, representing three digits of a number dialled by a telephone subscriber, may be received, the digits being stored on registers RG1, RG2 and the counterrespectively. After receipt of the first series, one of the counter tubes remains conducting and after a delay determined by the integrating network the associated tube in RG1 conducts; the consequent rise in potential in point Q prevents any further tube of RG1 conducting and causes a 'positive 'extinguishing pulse to be sent to TS via tube Bd. The digit represented by the next pulse series is similarly transferred to register RG2 which is caused to operate after RG1, either by controlling the tubes B30- B39 from the point Q which, as shown, is connected to their electrodes f through resistors R50, R51 &c,. or by making the time constants of the integrating networks such as R40, C31 associated with R62 greater than those of the networks such as R30, C21. When one of the tubes B30- B39 conducts, the rise in potential in point R causes another extinguishing pulse to be sent to counter TS after which if receives the third pulse series. One tube in each of the circuits TS; RG1, RG2 is then ignited and the higher cathode voltage of these tubes may be used to indicate the stored digits.
