Title: Improvements in and relating to machines for stripping waste yarns from bobbins
IPC: B65H73/00
Filed: 1949-10-27
Abstract: 670,684. Stripping waste from bobbins. COURTAULDS, Ltd., FARMER, H. O., and BOLSTRIDGE, T. Oct. 26, 1950 [Oct. 27, 1949], No. 27579/49. Class 120(iii) [Also in Group VIII] In a machine for stripping waste yarn from flanged bobbins comprising mechanism for feeding the bobbins in succession first to a cutter and then to a stripping device for removing the cut yarns, the cutter comprises two or more knives the total effective length of which normally exceeds the greatest distance between the flanges of the bobbins and the extreme knives are each associated with a guide which by contact with the inner surface of the corresponding flange adjusts the position of its associated knife so that it cuts into the corner of the bobbin but does not cut across the face of the flange. As shown, bobbins 1 to be stripped are carried on vertical spindles 2 each rotated in a bearing 25 in a travelling belt 3 by engagement of a sprocket 26 with a stationary chain 27. Overlapping knives 19, 20 are carried on blocks 9, 10 urged apart by springs 11, 12 and are pressed towards the bobbins by further springs. Engagement of the bobbin flanges 28, 29 with projections 15, 16 on blocks 9, 10 presses the blocks towards each other to adjust the overall length of the knives exactly to the distance between the flanges. As the knives press against the passing bobbin they cut the waste yarn thereon; the bobbin subsequently passes a buffing roller, which is associated with an air suction device and removes the severed yarn, and a polishing roller, and is then conveyed by belt 3 to a receiving bin.

Title: Improvements relating to coinfreed delivery and change-giving mechanism
IPC: G07F5/24
Filed: 1925-11-04
Abstract: 264,943. Pearse, W., and Morris, E. E. Nov. 4, 1925. Coin action, with optional use of coins of different value with change-giving, and multiplecoin.-In a combined coin-freed delivery and change-giving mechanism, the coins of lower denomination inserted for effecting delivery of articles are diverted in succession to the different reservoirs of a plurality of coin reservoirs equal in number to the number of such coins, which may have to be given as change when the apparatus is freed by a coin of higher denomination than the value of an article. As applied to a ticketvending machine taking pennies, sixpences and shillings, the pennies b, Fig. 1, are diverted in succession to five reservoirs a<1> - - a<5> by four three-armed levers c. A penny entering the reservoir a<5> depresses the tail c<1> of the fourth lever and raises its flaps c to divert the next penny to the reservoir a<4>. This next penny tilts the third lever and by acting against an arm c<2> of the fourth. lever resets it. When a penny has entered the reservoir a<1> the next penny runs over the flaps c to reservoir a<3> and the sequence begins anew. When a penny drops into a reservoir it acts on a lever a causing arms d<1> to dip into mercury baths to complete an electric circuit for actuating a ticket-delivery mechanism of the kind described in Specification 226,360. When a sixpence is inserted in a separate slot it actuates the ticket-delivery mechanism and closes the circuit of a solenoid which displaces, against the action of a returning spring, a slide e to withdraw a penny from the bottom of each reservoir, as change. The sixpences pile in a tube f, Fig 2, so that, when a shilling is inserted, another slide g actuated by a solenoid g' withdraws a sixpence while the slide e is withdrawing five pennies. The machine can be set to give tickets at a price more than one penny and less than sixpence by blocking access to one or more of the reservoirs a<1> - - a<5> by wedge pieces such as j<1>, Fig. 1. Certain of the contacts d, d<1> are cut out and also some of the reservoirs are obstructed at the bottom by shutters inserted in slots k<1>. Coin-slit closing-devices.-When any of the reservoirs a<1> - - a<5> become empty, a. lug l<1>, Fig. 2, on a spring-pressed plunger l provided on the slide e opposite that reservoir, makes contact with a bar m and completes an electric circuit. Magnets are thereby energized and release a spring-controlled shutter to close the sixpenny insertion slot. Normally the plungers l encounter the superposed pennies which prevent the lugs l<1> from contacting with the bar m. A shutter for the shilling slot is similarly released when the sixpenny tube f becomes empty.

Abstract: 1436455 Liquid immersed siren; slip clutches; control of A.C. motors SCHLUMBERGER INLAND SERVICES Inc 15 June 1973 [15 June 1972 (3)] 28619/73 Heading G5J [Also in Division H2] To transmit from the bottom of an oil well to the surface sonic tones, frequency or phase modulated to indicate the value of physical variables at the well foot, a siren interrupting the downward flow of drilling mud is driven by a two-phase induction motor, itself supplied variably via a control unit from a mud-driven turbo-generator, all situated at the foot of the well. Mud passes through longitudinal rotor slots 136 alternately aligned with-or-opposed to stator slots 130. If debris locks the rotor while the slots are obstructed, increased pressure differential causes oil from elastomeric bar 153 to force the stator 127 downward against spring 151, allowing debris to clear. Simultaneously, whether the slots are obstructed or not, slippage or torque clutch 41, with three balls 142 in cam recesses 139, 140, causes rotor 133 to move upward, again allowing debris to clear. In other embodiments the rotor, below the stator, is withdrawn by excess differential pressure only (Fig. 2, not shown) or by excess pressure differential and by excess torque by means of helical grooves (Fig. 5, not shown). If the separation of the rotor and stator fails to clear the obstruction, the circuit of Fig. 9 detects the discrepancy between intended and actual speed, and initiates count 262 of supply cycles. When a preset munber is reached, one phase of the motor supply is reversed 225; causing the torque to reverse, at the same time resetting the counter. Alternate torque reversals continue until the debris is cleared and normal working resumes.
