Abstract: 714,444. Tape dispensers NEUBRONNER, C. Jan. 15, 1952 [Jan. 17, 1951], No. 1103/52. Class 18 An adhesive tape dispenser comprises a guideway 4 for the tape and a pivoted cutter 11 mounted on a sliding carriage 9 above the guideway the cutter engaging the tape as the carriage is moved down over the guideway so as to feed the tape from the device. At the end of the carriage stroke the cutter engages a slot 16 to sever the tape. The cutter may be pointed so that only its point engages the tape during the feeding movement. In an alternative arrangement, Fig. 5, the cutter support may pivot backwards so that its rear portion 22 covered with rubber may engage the tape to feed it. A plate 17 is resiliently mounted in the slot and is engaged by the cutter at the end of its movement. The carriage 9 which is slidable on rails 8 is urged by springs 13 to its initial feeding position, a stop 23 being provided to limit the movement of the carriage, thereby determining the amount of tape to be fed A scale may be provided on the guideway 4. A moistening brush 21 in a water container 20 is positioned adjacent the forward end of the device, the tape being guided against the brush by a plate 19.

Title: Improvements relating to electric incandescent lamps
IPC: H01K9/04
Filed: 1929-01-18
Abstract: 321,360. Leff, M. Jan. 18,1929. Multiple-filament lamps have a continuous length of filament divided into two sections, which are normally connected in series between the terminals, and means for short-circuiting or cutting out either section to enable the other to be used alone. In the construction shown in Figs. 1 and 4, the filaments 8, 9 are connected in series between terminal contacts 2, 4, and their junction 10 is connected to a contact 3 on which a filament selecting-arm 20 is pivoted. When this is rocked to the right to bring its resilient finger 21 into engagement with the contact 4, the fila- ;ment 9 is short-circuited and the filament 8 lighted, and when rocked to the left to bring the finger 19 into engagement with the contact 2 the filament 9 alone is lighted. Modifications of the selector arm are described. In the construction shown in Fig. 8 a pin 32 is inserted in either of the two positions shown to short-circuit a filament. In a further construction, an insulating- disc 33 carries conductors 34, 35, Figs. 9 and 10, adapted to contact on one face with the plungers of the holder, and on the other face with the contact 3 and either of the contacts 2, 4. A screw-cap lamp is described (Fig. 11, not shown) having an arrangement similar to that shown in Fig. 4 mounted in its cap. In the screw-cap lamp shown in Fig. 13 a clip 39 is used to connect the terminal 3 with either of the contacts 2, 4.

Title: An improved automatic stopping device for gramophones
IPC: G11B19/14
Filed: 1956-01-20
Abstract: 787,108. Gramophones; stopping devices. MALATESTA, R. Jan. 20, 1956 [July 26, 1955], No. 1919/56. Class 40 (2). Two opposed trigger levers 3 connected to the motor switch and positioned one on each side of a cam 2 rotating with the turntable spindle 1 are lightly frictionally coupled to each other and to the gramophone pick-up so as to be capable of being shifted simultaneously away from or towards the cam 2, the coupling allowing independent movement of the levers. A slide 12 connected to the pick-up moves to the right as the pick-up travels towards the centre of the record and rotates pins 4 by means of levers 111 connected by a rod 13. The pins 4 have tapered points mounted in bearings, and each lever 3 is frictionally connected to a pin 4 by resting on a Range with interposition of a paper disc and is counter-weighted at 9. During the final runout of the pick-up, inclined surfaces on the cam 2 engage under the ends of the levers which thereupon tilt about the pins 4 and raise a bracket 10 whereby the motor switch is operated. The levers 3 are reset during the final part of the return of the pick-up by means of catches 14 on levers 211. To prevent the levers 3 from slipping off the cam a groove on the cam engages a tooth 103 on each lever or vice versa. Should it so happen that one lever 3 engages the cam 2 in such a position that the lever instead of being raised is pushed back the other lever engages the lobe of the cam after half a turn.

Title: Improvements in thermostats
IPC: G05D23/02
Filed: 1929-01-21
Abstract: 327,775. Grayson, J. H. Jan. 21, 1929. Thermostats.-A valve 19 for controlling the flow of fluids, particularly the gas supply to a water heater, oven, or the like, is thermally actuated by a rod-and-tube type thermostat 5, 6, and is provided with a snap action. The valve stem 23 is sleeved over the moving element 5 of the thermostat, the end of the valve stem being in close proximity to a dished diaphragm or metal disc 30 through which the rod 5 passes freely. The edge of the diaphragm is freely supported in a recess in the valve casing, the face nearest the valve bearing against a shoulder 31, whilst a block 35 having a projecting face of the form shown in Fig. 3 bears against the opposite face of the diaphragm, the circle of contact being located near the free edge of the diaphragm. The block 35 is secured to the rod 5, a shoulder on the rod bearing against the block as the tube 6 contracts until the diaphragm " clicks " past its neutral position, thereby opening the valve, with a snap action against the pressure of a spring 26, the valve closing automatically when the temperature has risen sufficiently to cause the tube 6 to expand until the rod 5 has moved the block 35 far enough to allow the valve to seat. Adjustment of the valve opening may be effected by a lever 12 secured to the end of the rod 5, the opposite end of the rod being threaded into a screwed plug 10 fixed in the end of the tube, the lever 12 moving over a calibrated dial. A bye-pass 18 provides for the gas supply to a pilot light.

Abstract: 960,796. Electric selective signalling systems. BROWN, BOVERI & CO. Ltd. Jan. 17, 1963 [Jan. 19, 1962], No. 2088/63. Heading G4H. In a transformer tap selecting system for an electric traction vehicle the position of a control lever 8 is compared 7 with the position of a tap selecting contact 6a to control a motor 9 so as to achieve agreement. The position of the control level 8 is represented by a single differentially timed pulse selected by a contact 4a from a clockpulse distributer 2. The position of the tap selecting contact 6a is similarly represented and these are compared by a transformer having two oppositely poled primaries 70a, 70b and a secondary 70c. If the control lever and the tap selecting contact are in agreement then the two differentially timed pulses cancel each other out and no signal is induced in the secondary winding 70c. However if the positions disagree one pulse will occur before the other and will, via transistors 75, 76, appropriately energize motor 9 so as to move the tap selecting contact 6a in a direction to achieve agreement. The first pulse that occurs also, via a second secondary winding 70d stops the second pulse being produced.
