Title: Improvements relating to selective switching means
Inventor: FORBES CHRISTOPHER JULIAN
IPC: H01H67/22
Filed: 1961-05-31
Abstract: 943,964. Electric selectors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 31, 1962 [May 31, 1961], No. 19676/61. Heading H1L. A plurality of contact groups 18 are capable of being selectively operated and re-operated so that a number of such groups may be operated at any one time by an electrically-driven selecting mechanism including driven cam means 1, 2, an assembly of deflectable fingers 4, 5, 6, 7 associated with the respective contact groups 18 and effective to produce operation thereof in response to predetermined deflection of the deflectable fingers, latching means 10 effective in its operative condition to latch on to free ends 9 of undeflected fingers and effective in its inoperative condition to permit deflection of the fingers by the driven cam means 1, 2, and means for controlling the operation of the latching means 10, whereby only the deflectable finger associated with the contact group to be selectively operated will be deflected (at least partly by the cam means 1, 2) to an extent sufficient to operate its associated contact group. To operate a particular contact group 18, an energizing circuit for the winding 12 of an electromagnet 13 is established through the normally closed auxiliary contacts 17 operable by the deflectable finger, say finger 6, associated with the selected contact group, there being one set of such contacts 17 associated with each finger. The electromagnet 13 displaces the latching plate 10 to the left (as viewed in Fig. 1) against the thrust of a biasing spring (not shown), thereby releasing the ends 9 of the deflectable fingers 4-7. At the same time a circuit is completed for the driving motor of the cam cylinder 2 which turns through one complete revolution, the helical protuberance 1 deflecting each of the fingers in turn until it reaches finger 6 which breaks the circuit of the electromagnet 13 by opening its contacts 17. The latching plate 10 returns to its operative position, latching on to the free ends 9 of the undeflected fingers but further deflecting the already deflected finger 6 so that it causes operation of its associated contact group 18 through either a latchable two-part plunger 21, Figs. 3 and 4, or a ratchet-driven cam 27, Fig. 6. The deflected finger 6 is allowed to return to normal by a subsequent momentary re-operation of the latch magnet 13 or by the operation of a further contact group 18. A second similar sequence of operations causes the release of the operated contact group 18 associated with finger 6.

IPC: B65G47/68
Filed: 1952-08-06
Abstract: 717,636. Conveyers. MEYER MANUFACTURING CO., G. J. Aug. 6, 1952, No. 19792/51. Class 78(1). In conveyer apparatus wherein a mass of articles is advanced in haphazard formation to the entrances to a plurality of parallel paths defined by fixed upright guides, a movable divider plate extends towards the approaching mass from the end of each of those guides which separate the paths, the divider plate being in the same vertical plane as its associated guide, in which plane it is reciprocated in a horizontal path to prevent jamming of articles and cause equal numbers to enter the several paths. As shown, Fig. 12, bottles are carried by endless chain slat conveyers 12, 13 between a pair of guides ga, gb to a plenum chamber formed by guide ga and a movable wall portion 64 where they spread onto two further slat conveyers i o, i 1 and enter the four channels formed by five guides 5, 6, 7, 8 and 9, the guide 9 being a continuation of guide 9a. The arrangement is such that a conveyer 10, 11, 12 or 13 runs beneath each of the respective channels at their entry ends, but, as shown in Fig. 1, by suitable arrangement of the forward parts of the guides the channels are led in turn across the various conveyers to respective ones of the deflectors 1-4 which deliver articles from the channels into respective machines A, B, C, D, e.g. labelling machines. In advance of the entry ends of the guides 6, 7, 8 are the divider plates 43, 44, 45 which are oscillated forwards and backwards in their own planes through connecting rods 52 (not shown), 53, 54, Fig. 5, by cranks on a crankshaft 55, the cranks driving connecting rods 52, 54 being 180 degrees out of phase with the crank driving connecting rod 53. The extensions are guided in their movement by horizontal rails 46 and the adjacent ends of each extension and its guide are contoured as shown to minimise the danger of an operator's fingers being caught. The conveyers 10, 11, 12, 13 and further conveyers, Z1, Z2, Z3 for removing the bottles from the machines A, B, C, D are all driven from a common motor M as shown, Fig. 1, the conveyer chains acting as driving connections. A stop member 70 carried by a pivoted arm 7 1 is arranged as shown, Fig. 12, such that upon overcrowding of bottles in the plenum chamber, wall 64 is moved outwards against the tension of a spring 65 whereby opening a valve 66 admitting fluid to a cylinder containing a piston 77 which forces the member 70 out between the guides 9a, 9b against the tension of a spring 76 which withdraws it again after the blockage is cleared and valve 66 has been closed.

Title: Container closure
IPC: B65D47/28
Filed: 1939-07-08
Abstract: 531,010. Closures for collapsable tubes. KATES. F. L. July 8, 1939, No. 19935. [Class 125 (iii)] A closure for a collapsable tube 10 containing cream, tooth paste or the like comprises a cap 12 which is tightly fixed to the neck 11 of the container by screwing or some similar method, and has a slot in its top occupied by a slide 18 which normally closes the slot. The parts of the slide and slot in sliding engagement are of dovetail form, while the end wall of the slot has its opposite sides bevelled to form a sharp edge 15 and the end of the slide is shaped in a complementary manner. This causes extruded material to be cut off when the slide closes the opening. A headed pin is passed through the slide 18 and the head 20 forms an operating knob while the shank 21 of the pin projects beneath the slide and engages the wall of the cap when the slide is in its open position so that the slot is open for a pre-determined distance irrespective of the thickness of the wall of the tube neck. In the form shown in Fig. 3 the top of the neck does not engage the inner face of the cap so that room is left for the shank of the pin. In other forms a slot is made in the wall of the neck to permit passage of the shank. The cap may be secured by a bayonet joint.

Patent GB-865525-A (GB)
Title: Improvements in or relating to electric motor controllers
IPC: H02P25/26
Filed: 1957-06-25
Abstract: 865,525. Control of A.C. motors; controllers. IGRANIC ELECTRIC CO. Ltd. June 25, 1957 [June 25, 1956], No. 19976/57. Class 38 (3). A press motor PM is operated at a low speed in a forward direction by actuating an inching switch 90 to close contacts 91, 92, whereby relay FCR is energized and the circuit of forward contactor F is closed. If a manual switch MS is initially placed in its medium or high torque positions, M or H, then relay TCR temporarily energizes contactors 4A or 5A to shunt secondary resistors 44 or 45 to provide an adjustable starting torque for the motor. After a time delay, a relay 1TR opens its contacts to de-energize the relay TCR, and the press now runs forward at a low speed which is determined by all the speed-regulating resistors except resistor 46 being in circuit. The opening of trip switch 73 de-energizes contactor SS to insert resistor 46 in the secondary circuit. To operate the motor at a predetermined speed and to obtain gradual acceleration, a drum switch D is preset at one of thirty-two steps Fig. 3 (not shown). Press-button contacts 91, 92, 93 are closed temporarily and contacts 95 are opened, so that relays ICR, FCR are energized. A coil PR3 is rendered effective to set plugging relay PR in its dotted-line position, and contactor F is closed to start the motor at a low speed. The release of relay 1TR energizes timing relay 2TR so closing contacts 2TR3 for completing a circuit to the drum switch D which is assumed to be set at its thirty-second step. Thus, contactors 1A, 2A, 5A close to shunt resistors 41, 42, 45 and, after time delays, contactors 4A, 3A are energized in sequence to accelerate the motor to its final speed. The speed of the motor may be reduced, without resetting the switch D, by opening push-button switch 95 to interrupt the circuit of relay 2TR. This causes contactors 1A-5A to release and reinsert secondary resistance whereby the motor is decelerated. The actuation of safety limit switch 73 de-energizes contactor SS so that all of the secondary resistance is reinserted without resetting switch D and the motor operates at a very low speed. To stop the press by reversecurrent braking, switch 75 is opened to deenergize relays ICR, FCR, so opening contactor F and reinserting resistors 41-45. Relay RCR closes to establish a circuit for contactor SS and to short-circuit resistors 46, 53, 54, whereby constant resistance is maintained in series with coil PR2 of plugging relay PR regardless of the setting of switch 56. The closure of contactor R applies reverse power to the motor, and coil PR1 is energized to oppose coil PR2. At zero speed the current in coil PR2 is reduced and coil PR1 becomes effective to reset the plugging relay and to open the contactor R. The motor is operated in the reverse direction by closing push-button contacts 97, 98. Specification 613,024 is referred to.

IPC: F02M7/11
Filed: 1929-06-28
Abstract: 338,895. Arnott, F. H. June 28, 1929. Spray carburettors.-Fuel maintained at a level 22 in a float chamber 1 and auxiliary chamber 6, produces a constant gravity head on a discharge orifice 28 located in a plug 10 inside a suction-actuated air valve 21 which, in its movement, actuates a fuel needle valve 26. Fuel is supplied to the orifice 28 through duct 29, annular passage 30 and duct 31, and the movements of the needle valve are damped by a light piston 23 in chamber 6. Air enters through passages 18 in an adjustable plug 15 upon which the air valve rests when there is no suction. The space 33 around the air valve is connected with the otherwise sealed air space of the float chamber through a, duct 32. The fuel reaches the air stream. through a slit 20 in the bottom of the air valve, and grooves 35 on the plug 10 tend to prevent too great a difference of pressure between space 33 and the interior of the valve. The chamber 6 communicates with the air space of the float chamber through aperture 4. and is further connected by a tube 9 to valve 38, Fig. 4, within reach of the driver. This valve has graded inlet apertures 36, and permits of the pressure at the top of the float chamber being varied. Up to about one-third of maximum suction, the air and fuel valves are simultaneously and progressively opened. After that they are brought to rest and an increased suction acts upon a fixed jet and air valve opening. Specification 170,970 is referred to.
