Title: Improvements in or relating to automatic delivery units
Inventor: HIGGINS EDWARD LAWRENCE
IPC: G07F11/32
Filed: 1951-09-26
Abstract: 731,924. Sales and sale service. BRITISH VITAMIN PRODUCTS ENGINEERING CO., Ltd. Dec. 29, 1952 [Sept. 26, 1951], No. 22499/51. Classes 27 and 116. An automatic delivery unit for liquid containers which are gravity fed and held against delivery by a gate adopted when actuated to permit the passage and delivery of a prescribed number of containers has means for delivering simultaneously one or more drinking straws. As shown in Fig. 1, a heat insulated cabinet has inclined guideways 14 for bottles 12 leading to vertical shoots 16 having star wheels 22 at the bottom which are released to deliver one bottle under gravity and a straw 26 from a compartment 25 between the shoots 16. Each guideway ends with a pivoted flap 17A, 17B which has an end blade spring 19 and is spring-urged upwardly by a spring 18, the flap only allows movement of bottles from a guideway when the next higher guideway has been evacuated. The star wheels 22 are mounted on shafts splined to a shaft 32 in a detachable casing secured to the back of the apparatus. The shaft 32 has three, six toothed cams 33, 34 and 35. The cams are rotated simultaneously; the cam 33 delivers a bottle, the cam 34 is a safety device and the cam 35 releases a straw. The cam 35 has a pawl 37 mounted on a pivot also carrying a lever 40 adjustably bolted to the pawl. The end 42 of the lever is urged by a spring-pressed plunger 43 to engage a pivoted contactor arm 44 of an electromagnetic relay 45 which is operated by a coin to rotate the contactor arm and pawl 37 to allow the weight of the bottle 12A to rotate the star wheel and release a bottle. The pawl 37 being then returned by the plunger 43. To prevent more than one bottle being delivered inadvertently, a pivoted pawl 38 is urged by a spring- pressed plunger 46 to contact the cam 35 and has a sear engaging a sear 47 on the pawl 37 whereby rotation of the pawl 37 rotates the pawl 38 which re-engages with the cam and with the pawl 37 after the delivery of a bottle. To ensure the pawl 38 has time to re-engage with the cam; the movement of the cam is braked by a spring- pressed plunger 49 engaging the second cam 34 which has its teeth facing in the opposite direction. To release a straw arms 51 contact the cams 35. The arms are mounted on a rotatable shaft 52, Fig. 6, connected by a lever 54 with a lever 55 pivoted to a lug on a pair of lever arms 57 pivoted at 58. The end of the levers 57 engage between stops 59 on a shaft 27 under the action of a spring 60. When the cam 35 rotates, the arms 51 also rotate to cause the rod 27 to move longitudinally to disengage a straw. The rod is returned by the spring 60. The apparatus may selectively dispense one or two kinds of bottles. A refrigerating chamber below the guideways circulates cooled air through rotating vanes 28 and pipes 29 with holes.
Patent GB-736316-A (GB)
Title: Improvements in and relating to electric remote control systems
Inventor: ROSS THOMAS WYLIE
IPC: H02J13/00
Filed: 1952-09-01
Abstract: 736,316. Electromagnetic relays. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 30, 1953 [Sept. 1, 1952], No. 22530/52. Class 38 (5). [Also in Group XXXVIII] In a remote control system using ripple currents transmitted e.g. over an energy distribution network, complementary operation such as the switching on and off of a load circuit are effected by a single relay responsive alternatively to two different ripple frequencies (or rhythmic modulations thereof). When the relay responds to one ripple frequency to effect the corresponding operation (" on " or " off") it adjusts, at the same time, the mechanical resonance of the relay to the second frequency. Similarly when the relay responds to the second frequency to perform the complementary operation it readjusts the resonance frequency of the relay to the first frequency. The resonance relay comprises a vibratory strip 2 anchored at its ends 3, 4 and carrying a permanent magnet 1 co-operating with coils 5, 6. When these are energized in known manner (not shown) from the lines S1-S2 by a ripple current modulated at the first frequency f1, the oscillations of the strip 2 build up to close contacts 8, 9 to energize the coil 13 of a contactor c of the stable twoposition type, over its armature contact 18. The contactor armature 14 is thereby rocked to its other position where it is held by a spring detent arm and roller 17 ; it closes the load circuit L at contacts 29-30 and rocks a twopoled cam 25 to separate the arms 33-34 of pivotal levers against the bias of a spring 41 so that the opposite ends 38-39 of the levers grip the strip 2 at an intermediate point and after its mechanical resonance frequency to f2. The resonance relay will then respond only to a ripple (or modulation thereof) of frequency f2, when contacts 8, 9 close to energize the coil 21 over the armature contact 18 to reverse the contactor, open the load circuit L and release the strip 2 at 38-39 and so alter the relay resonance frequency back to f1.

Abstract: 1351294 Optical projection apparatus AGFA-GEVAERT A G 19 April 1971 [25 March 1970] 22934/71 Heading G2J Two slide projectors 1, 1<SP>1</SP> are linked to a controller 2 for producing a dissolve effect during slide-changing when the slides are alternately projected from one of the projectors 1, 1<SP>1</SP> on to the same screen area. As shown each projector includes fan motor 5, 5<SP>1</SP>, cooling fan wheels 6, 6<SP>1</SP> and windings for magnetic coupling 8, 8<SP>1</SP> on shafts 7, 9 and 7<SP>1</SP>, 9<SP>1</SP> and a slide changing mechanism within the housings 3, 3<SP>1</SP>. To produce slide changing, switch 11 is closed rotating pinion 13 anti-clockwise by means of motor 10 and shaft 12. This lowers and raises racked members 14, 15 respectively so opening contact 18 and de-activating coil 8 and lowering and raising respectivley the resistance in rheostats 16, 17 connected to electrical supply 22. This causes the projection 1<SP>1</SP> to dim and projector 1 to increase its illumination (hence dissolve on screen). When members 14, 15 are almost at the end of their permissible movement switch 11 is opened and the member 15 closes contact 19. In the position shown motor 51 was operating and motor 5 stationary. The described movement of members 14, 15 causes the power to motors 5, 5<SP>1</SP> to increase and decrease respectively. However the wheels 6, 6<SP>1</SP> act as flywheels and so as the power to motor 5<SP>1</SP> decreases the rotation of the shaft 7<SP>1</SP> is maintained by wheel 6<SP>1</SP> The closing of contact 19 permits the power now supplied wholly through rheostat 16 to activate coil 8<SP>1</SP> so that the wheel 6<SP>1</SP> drives shaft 9<SP>1</SP> and there is sufficient momentum left to perform one slide change operation. Subsequent operation is again inititated by closing the switch 11, when the pinion 13 rotates in the reverse direction. Reversal of the motor is achieved by any suitable means.

Title: Improvements in or relating to submersible electric motors
Inventor: LUNG KENNETH RAYMOND
IPC: H02K5/132
Filed: 1960-07-05
Abstract: 896,247. Centrifugal switches; fluid actuation of switches. TAIT MANUFACTURING CO. July 5, 1960, No. 23487/60. Class 38 (5). [Also in Group XXXV] A submersible liquid-filled motor for driving a pump with a shaft within a casing incorporates a switch movable between a starting and a running position by an operating member inside the casing which is normally biased to maintain the switch in a starting position, and is moved by a pressure differential on opposite sides of the operating member produced by a pump driven by the motor shaft. The motor includes a starter 20 carrying main field winding 21 and the starting winding and a rotor 23 secured to shaft 25 whose lower end is supported by bushing 27 in a bracket 30 bolted between end ring 31 and end housing 15. The starting and running circuits of the motor include a starting mercuryswitch 35, a starting capacitor 36, and the starting and main windings 22, 21, respectively. Switch 35 mounted on an arm 40 pivoted at 41 on a mounting 42 carried by bracket 30 is biased by spring 44 to its open position. A spring 52, stronger than spring 44, biases the plunger 51 which slides in the hollow portion 50 of the lower end of shaft 25, against the switch arm 40, so forcing the switch to its closed position. With switch 35 in its closed position, when the motor is first energized, an impeller formed by a disc 55 with radial passages revolves with the motor shaft, developing suction in shaft portion 50, overcoming the force of spring 52, causing spring 44 to push up switch arm 40, and shift switch 35 to the running position. A rubber diaphragm 16 forms a flexible seal between the interior of the motor and the outside atmosphere. In another embodiment described with reference to Figs. 5, 6 (not shown), 7, the centrifugal impeller is secured to the lower end of the motor shaft 61 by screw 96 and lock-washer 97, an extended tubular cylindrical inlet portion 99 forming a guideway for a plunger 100, which is the operating member for a switch 75, Fig. 7. Spring 101, mounted in inlet 99, biases the plunger 100 downwardly to cause its pin 102 to engage the switch button 91 closing switch 75. In this embodiment, the diaphragm is replaced by a bellows which is arranged to operate a cut-off switch when fully expanded.
