Abstract: 433,132. Printing - machines. STRACHAN & HENSHAW, Ltd., FOWERAKER, T. S., and SARGENT, T., Whitehall Iron Works, Whitehall, Bristol. Feb. 6, 1934, No. 3933. [Class 100 (ii)] Inking-apparatus.-In a printing-machine using rapid drying inks having a high solid content, the forme-inking roller c of non-resilient material e.g. cast iron, steel, or glass, frictionally drives a similar non-geared duct roller d, and means are provided whereby these rollers continue to run after the forme roller b and impression roller a are brought to rest, so that drying of the ink during non-printing periods is prevented. In one form of driving device, Fig. 1, the rollers a, b are geared together by fast gears e, f and carry loose gears g, h meshing respectively with a gear o on a drive shaft m and a gear k fast on the shaft of the roller c. A second gear n on the shaft m normally engages a gear l fast on the shaft of the roller a. By axially moving the shaft m, the gears n, l are disengaged, bringing the rollers a, b to rest but permitting continued drive of the roller c through the gears o, g, h, k. In a modification, the inking - rollers are driven during non-printing periods by gearing from a slow running electric motor. The roller d is preferably set out of contact with the roller c so that it is driven by the ink film at a speed slower than that of the roller c. The duct i is removably supported by spring catches y<2> carried by brackets y<1> which are adjustable by screwed rods 10 to move the roller c out of contact with the roller b during non-printing periods. Inkagitating fingers p, Fig. 3, are carried by a member n which is slidably mounted on a bar v fixed to the duct i, and is reciprocated thereon by a block q reciprocated on a bar r fixed to the brackets y<1>, a forked arm s on the block q engaging a pin t on the member u. The block q is actuated by a cam y fixed to a gear z meshing with the gear k. The duct roller d, Fig. 6, is preferably mounted in ball bearings and has hollow unsupported ends whereby the shaft may flex somewhat while maintaining even contact of the roller with the roller c. The printing-formes may be prepared as described in Specification 432,716.

Patent GB-457691-A (GB)
Title: Apparatus for the automatic stopping of gramophones and the like
IPC: G11B17/02
Filed: 1936-02-14
Abstract: 457,691. Gramophones. BOSCH AKT.- GES., R., 4, Militõrstrasse, Stuttgart, Germany. Feb. 14, 1936, No. 4471. Convention date, June 24, 1935. [Class 40 (ii)] An automatic stopping-mechanism for gramophones and the like, wherein a controlling member executes to-and-fro movements during the playing of a record, is characterized in that the movement of the said member in one direction is produced by a magnet or magnetic armature acting for a short time on the member. In the construction shown, a lever 16 is pivoted at 12b, so as to be movable in a vertical plane, on a lever 12, which is mounted on a pivot pin 10 on a frame 7 suspended in the motor-board. The lever 12 has a frictional connection with a lever 11 arranged on the same pivot 10. The lever 11 has an upstanding pin 15 adapted to be engaged by impact pins 5, 6 on the tone-arm socket 2. The outer end of the lever 16 rests on a notched support 9, and the lever carries a permanent magnet 17 and also a mercury switch 19 in the motor circuit. Attached to the turntable is an armature 20, which passes close by the magnet 17 as the turntable revolves. During the playing of a record, the tone-arm moves the levers 11, 12, and thereby the lever 16, so that the outer end of the latter moves towards the notch 9a in the support 9, but whilst the needle is in the sound-groove, each time the armature 20 passes the magnet 17, the magnetic attraction restores the lever 16 to a position against a rubber-covered stop 21 on the support 9. When the needle enters the runoff groove at the end of the record, the increased movement of the tone-arm causes the lever 16 to be moved sufficiently for its outer end to drop into the notch 9a, whereupon the tilting of the mercury switch breaks the motor-circuit. A pin 23 on the underside of the lever 11 resets the lever 16 when the tone-arm is moved back to the starting position, and the motor is then switched on again. The positions of the magnet and armature may be interchanged, or the magnet system may be otherwise modified. The stopping-mechanism may be arranged in a small box adapted to be fitted on the motorboard of a gramophone, a feeler arm projecting from the box into the path of the tone-arm. The turntable may be of moulded synthetic resin, with the armature or magnet cast into it. Specification 457,690 is referred to.

Abstract: 675,324. Switch covers. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 23, 1950. [Feb. 22, 1950] No. 4599/50. Class 38 (v). A safety arrangement for electric apparatus comprises an interlock switch 3 arranged to interrupt the supply to the apparatus when a part 2 of the apparatus, e.g. a door or cover, is moved from a normal operating position, a control member 6 being provided whereby the supply circuit may be completed when the part 2 is away from its normal position, the member 6 being held in a circuit-completing position by a latch 8 which is tripped when the part 2 is restored to its normal position. The switch 3 is normally held closed by a rod 5 on the part 2 acting through member 6, Fig. 4, removal of the part 2 allowing the plunger 4 to move to the right to open the switch. After such removal of part 2, the plunger 4 may be moved to the "on" position by the member 6, this movement of the plunger being greater than before so that the bell-crank latch 8 can drop behind the member 6, Fig. 5. Restoration of part 2 causes a shoulder 13 thereon to trip the latch and allow the plunger 4 to move to the right again until member 6 abuts the rod 5, the switch 3 now being under the control of the part 2 again.

Feb. 13, 1931, No. 4609. Convention date, March 5, 1930. [Class 106 (ii).] Relates to gauges of the type having a telescopic indicator and consists in a casing, pressure responsive means operating indicating means having a plurality of pressure ranges in which the spacing of the indicia in each range is equal but differs from the spacing in another range, and a spring resisting the pressure responsive means, the resistance up to a point governing one range and beyond governing a second range of pressures. The tube A is screwed into a fitting B provided with a foot portion b<1> fitted with a tyre deflating pin b<2>. The tube houses a plunger C fitted with a cup leather and a spigot c<1> which enters within a block d<1> carried at the lower end of an indicating bar D of rectangular or other section. The bar D is. surrounded by a spring F engaging at the lower end the plunger and normally forcing it down so that the cup leather is pressed out against the inner wall of the tube A by a wedge-shaped circular rib located in the head of the part B. The upper end of the spring abuts against the lower of two washers the upper one of which abuts against the turned over end of the tube. Located between the washers are a friction ring for retaining the indicator bar and a pad for holding lubricant. The washers are provided with rectangular slots through which the bar passes and thus allow of the bar being swivelled about the axis of the tube. The spring F is made with convolutions of the upper half spaced further apart than those of the lower half. In use the entire spring yields under pressure, but at a predetermined pressure the lower convolutions abut against each other and only the upper half of the spring is brought into active play. A ledge d<4> is pressed out of the bar to prevent it passing through the top of the gauge.

Abstract: 525,049. Television. GENERAL ELECTRIC CO., Ltd., CLAYTON, R. J., and EDWARDS, G. W. Feb. 13, 1939, No. 4672. [Classes 40 (iii) and 40 (v)] Disturbance between the line and frame time bases due to capacity coupling between the electrodes of a valve generating saw-tooth oscillations is compensated for by connecting the control grid to some other point in such a way that a voltage is applied to the control grid equal and opposite to the disturbing voltage. In the arrangement shown line-frequency saw-tooth oscillations are generated by means of a tetrode valve 1, of which the anode 3 is connected through the primary winding 6 of a transformer and a variable resistance 7 to the positive H.T. supply. A tapping on the secondary winding 8 of the transformer is connected in series with the biassing circuit 9 to the cathode 2, one end of the winding 8 being connected to the grid 5. The output circuit 10 is connected across part of the secondary winding 8. The control grid 4 is connected to the cathode 2 by a grid leak 11 and by a lead 12 to the common source of synchronizing signals. To prevent oscillations from reaching the lead 12 through the capacity 13 between the grids 5, 4, a condenser 15 is connected between the control grid 4 and the end of the secondary winding 8 remote from the grid 5. By varying the portion of the secondary winding 8 included in series with the compensating condenser 15, the magnitude and phase of the voltage applied to the grid 4 may be adjusted. In a modification the cathode 2 is connected through the biassing circuit 9 to the upper end of the secondary winding 8, and the compensating condenser 15 is connected directly between the control grid 4 and anode 3. In another arrangement the saw-tooth oscillations generated in the valve 1 are applied to an amplifier and the compensating condenser is connected between the control grid 4 and a point in the anode circuit of the amplifier. Specification 494,677 is referred to.
