Abstract: 964,344. Feeding sheets. PNEUMATIC SCALE CORPORATION Ltd. July 19, 1961, No. 26182/61. Heading B6B. [Also in Division B8]  A machine which inserts articles, such as a group of bakery rolls, into an envelope type bag (see Division B8) has an elevating means for holding a stack of the bags and feeding them to the machine. The bags 10 are retained on a detachable platform 12 by a U-shaped member 16 which passes through openings 17 provided in an extended flap portion 18 of the bag and a stationary hooked member 28 maintains the top of the stack at a constant level. The platform 12 is elevated, by means of a head portion 30, supported by a rod 36 sliding upwards in brackets 38 secured to a bar 40. A cord 44 is attached at one end to a bar 42 and at the other end to a recoil unit 50 to move the stack upwards smoothly, the cord passing along rods 36 and round a pulley 46 in between. The topmost bag is opened out to the position shown in Fig. 8 and thus separated from the underlying stack by an airblast blown into its open end by a fan 74 through a flap valve 82 opened at the appropriate time. Provision is made for locking the head portion 30 in its lowest position to facilitate the loading of a full platform. A contact member 386 is provided for engaging the platform when it is empty and closing an electric circuit to stop the machine.

Abstract: 284,025. Calvete, I. B. Oct. 23, 1926. Heating by electricity.-In hot air systems, particularly for drying the head and hair, and comprising one or more pipes a supplied with air by a central fan, the air being heated by an electric heater on each pipe, the throttle valve-operating lever d of each pipe is connected to the switch p of the heater and also to a starting switch for the motor driving the fan so that the heater and the air-blast are started and stopped simultaneously with the opening and closing of the throttle valve. As shown, the lever d is pivoted about the spindle c of the throttle valve b and is held in any desired position by a spring-pressed washer i mounted on a pin e on the lever and engaging the edges of a fixed arcuate slot g in which the pin e moves. The lever o of the switch p is operated by jaws m on an arm k fixed to the lever d. The other end of the spindle c has secured thereto the operating lever of a snap-action switch controlling the motor-started. The switch is enclosed in a casing q. The lost-motion of the switches is such that they are operated only on the immediate opening and final closing of the throttle valve b.

Abstract: 873,610. Laminates. PLASTA PRESSSTOFFWERK KOPPELSDORF VEB. Aug. 28, 1957, No. 27091/57. Class 140. A stock of fibrous sheets, which have been impregnated with synthetic resin hardenable to an infusible condition, and dried, has the top or bottom sheet, or each such sheet, coated on its outer side with an adhesive, dissolved in an organic solvent, having a good affinity for thermosetting and thermoplastic resins, a polyvinyl chloride sheet is laid on the coated surface, and the whole consolidated by heat and pressure. The fibrous sheets may be of paper, fibre-board, chipboard, textile fabric webs, glass fibrous fleeces or mats, or mats of glass staple fibre, or may contain wood chips. The synthetic resin may be a phenol-formaldehyde condensate, the adhesive polyvinyl chloride or polyvinyl acetate, and the solvent acetone. In a modification, particularly suitable when the fibrous sheets are smooth, e.g. paper, a layer of porous textile material is saturated with synthetic resin, dried and interposed between the top or bottom sheet and the coating of adhesive. In this case the solvent for the adhesive is one that will dissolve the synthetic resin in the adjacent layer. In an example, the synthetic resin is phenolformaldehyde, and the solvent acetone.

Abstract: 603,373. Induction regulators. BRITISH THOMSON-HOUSTON CO., Ltd., and BARWICK, E. C. Oct. 19, 1945, No. 27471. [Class 38 (ii)] [Also in Group XXXVII] A single induction regulator for the speed control of stator-fed polyphase A.C. commutator motors, which controls the voltage supplied to the commutator, has in each phase a stator winding 2 and a rotor winding in series, the latter being divided into two parts 3, 4 to the junction of which is connected one end of a secondary stator winding 6, and is so designed that the output voltage at 7 from the last winding comprises a component of variable magnitude and substantially fixed phase, and a component of constant magnitude and displaced phase of zero magnitude. Fig. 2 is a vector diagram giving voltage relationships of one phase for three different positions of the regulator. The supply voltage OC equals the sum of voltages OA, AB, BC across windings 4, 3, 2 respectively. Angle α is determined by the relative positions of windings 3, 4 on the rotor, and # is the regulator angle, varied by movement of the rotor. The voltage AP across winding 6 is at an angle #-180 degrees to voltage BC across winding 2 where # is an angle determined by the relative positions of windings 2, 6 on the stator. OP is the voltage output from winding 6. When OB equals BC and #-α=180 degrees the locus of P as # varies is a straight line. Three positions OP, OP<SP>1</SP>, OP<SP>11</SP> are shown for various values of # with corresponding points A, A<SP>1</SP>, All and B, B<SP>1</SP>, B". When # is zero OP<SP>1</SP> is perpendicular to the locus, so that in general OP is the sum of PP<SP>1</SP> of fixed phase and variable magnitude, and OP<SP>1</SP> of fixed magnitude and phase in quadrature with PP<SP>1</SP>. When OB and BC are of different magnitudes the locus of P is curved so that PP<SP>1</SP> varies slightly in phase, Fig. 3 (not shown). If OA and AP are equal, the locus of P passes through O so that there is no output component of fixed phase and magnitude, Fig. 4 (not shown). If α and # are not equal and do not differ by 180 degrees output voltages OP and OP<SP>11</SP> for equal and opposite values of # differ in magnitude, so that the motor has a greater speed range on one side of its synchronous speed. The rotor and stator windings may alternatively be on the stator and rotor respectively.
