Title: Telectrically operated synchronous motor speed adjusters
IPC: H02P25/02
Filed: 1973-11-26
Abstract: 1396679 Coin feed time switch WELWYN ELECTRIC Ltd 26 Nov 1973 54776/73 Heading G4V [Also in Division H2] A synchronous motor 3 is controlled by a circuit comprising a transformer and rectifier 7. connected to a fixed frequency supply 6 and supplying an oscillator 8 which feeds the motor through a power amplifier 10, a member 9 such as a variable resistor or capacitor being adjustable to set the oscillator frequency to a desired value and hence operate the motor at a desired speed. The motor is part of a coin freed machine of the type wherein insertion of one or more coins momentarily closes contacts 2 to start the motor, after which a motor-operated cam 4 closes contacts 5 to energize the motor for a predetermined time corresponding to the number of coins inserted, the cam opening the contacts 5 at the end of this time during which the motor drives other parts (not shown), of the machine. The time of operation may be adjusted according to the rate of value added tax by adjusting the member 9 and hence the speed of the motor. The transformer may be omitted, as can the amplifier 10 if member 8 is a power oscillator. Motor 3 and its control circuit may alternatively be used to drive the turntable of a record player.

[Also in Divisions C2 and G2] Ethylenically unsaturated compounds are photopolymerized by irradiation with actinic light in the presence of, as photopolymerization initiator, an oxido-oxazole of the formula wherein R 1 , R 2  and R 3  are the same or different and each represents a C 1 -C 3  alkyl group or an aryl or substituted aryl group, and R 4  represents a C 2 -C 3  alkylene group or an arylene group, the oxido-oxazole being in the form of the free base or the hydrochloride thereof. Photopolymerization can be effected in bulk, emulsion, suspension or solution. The polymerizable composition may optionally include a hydrophilic or hydrophobic binder, e.g. polystyrene, ethylene-maleic anhydride copolymer, polymethyl methacrylate, polyvinyl acetate, polyvinyl butyral, partially saponified cellulose acetate, gelatine, casein, starch, carboxymethyl cellulose or polyvinyl alcohol. There may also be present, as a thermal polymerization inhibitor, 2,6-di-t-butyl-p-cresol or, as a polymerization accelerator, potassium ferric oxalate. Specified as ethylenically unsaturated compounds are styrene, acrylamide, methacrylamide, methyl methacrylate, diethylaminoethyl methacrylate, acrylonitrile, divinyl benzene, glycol diacrylates, N,N<SP>1</SP>-alkylene-bisacrylamides, and polymers containing ethylenic unsaturation such as allyl esters of polyacrylic acid, maleic esters of polyvinyl alcohol, polyolefins containing residual double bonds, unsaturated polyesters, cellulose acetomaleates and allyl cellulose.

A plastics blank W, below its crystalline melting point, is clamped over the open end of a female die 10 by a plunger 13 and deep drawn into the die by a male plunger 15, the plunger 13 exerting sufficient pressure on the rim of the blank before or during drawing to express material inwardly to supplement the walls of the drawn article. The leading end of the plunger 15 is preferably coated with a low friction material to allow material to flow easily from under the plunger into the side walls. In the illustrated embodiment, the blank is initially sandwiched between the plunger 15 and a raised ejection plunger 20 after which both plungers are moved downwardly in unison, material being expressed inwardly during the drawing by plunger 13. Some shaping of the base of the article may be effected by the plungers if desired. In a second embodiment the ejection plunger is maintained in its lowermost position during the drawing. In a further embodiment (see Figs. 5 and 6, not shown) the female die is formed as a split blow mould and the drawn blank is expanded into contact with the mould by pressure gas passing down the drawing plunger. In the embodiment of Fig. 6 the rim clamping plunger is rotated to impart multi-axial orientation to the rim of the article.

In an arrangement comprising a hopper carriage 6 slidably movable on a framework 7, a weighing capsule 10 supported on the framework 7 is arranged to be engaged by a bolt 5 on the carriage 6 only during a weighing operation in which the load in a hopper on the carriage is to be measured, the capsule 10 otherwise being held out of engagement from the bolt, a manually controlled device being provided to effect such engagement and disengagement. The manually controlled device may comprise a handle 1 which is mounted on a rotatable shaft 15 supporting a cam 4 and which is spring- biased to one of two stable positions limited by stops 12, 13, the cam 4 being arranged in one embodiment to bear on the capsule 10 and urge it upwardly on rotation of the handle from its position limited by the stop 13 to its position limited by the stop 12 so that the capsule 10 then moves to engage the bolt for weighing purposes. In an alternative embodiment, the cam 4 is rotated to disengage a bolt 5 and allow a further bolt on the carriage 6 to engage with the capsule 10 mounted on the framework 7 during a weighing operation, the cam 4 being rotated to co-operate with the bolt 5 so as to lift the further bolt away from engagement with the capsule 10 when the weighing operation is complete. In both embodiments the handle may be automatically moved to its position limited by the stop 13 when the hopper carriage is moved upwardly relative to the framework 7 so that on its subsequent return the hopper carriage 6 cannot affect the weighing capsule 10 until the handle is rotated manually to its position limited by the stop 12.
