Title: Improvements in or relating to the roughening of parts of shoes
IPC: A43D37/00
Filed: 1935-03-06
Abstract: 453,150. Boot-making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(United Shoe Machinery Corporation ; 140, Federal Street, Boston,U.S.A.) March 6, 1935, No. 6987. [Class 17 (i)] [See also Group XXIII] Laying.-A machine for roughening simultaneously the face of the channel formed in a sole and the face of the channel flap, prior to the application of cement for securing the flap when laid, has a support to engage the flap, a gauge member adapted to extend into the channel and engage the base of the flap, a guard for the shoe upper, and means for sharpening the roughening tool, which tool, preferably, comprises a pair of wire bristle brushes of which at least one is of frusto-conical shape. An air blast is directed on to the work at the operating point, and dust is removed by suction. The tool is driven slowly in operation, and faster and in the reverse direction when being sharpened. A pair of frusto-conical wire bristle brushes 20, 22 are mounted on a shaft 18 on which is secured a pulley 24 adapted to be driven slowly by a belt 54 or faster by a belt 36, idle pulleys 26, 28 being provided for the belts when not in use, and gearing 46, 52 providing a reduction and reversal in the drive. This gearing also drives an air pump supplying a nozzle 74. Between the brushes, a gauge 90 engages the base of the channel flap, which flap is supported on the other side by a roll 116 on a stem adjustably carried by a bell-crank lever 122 linked to a second bell-crank lever 132 linked to a treadle 140. The lever 132 is urged to operative position by a spring 128, depression of the treadle swinging the roll away from the flap to allow change of work. An adjustable guard 110 protects the shoe upper. A dust-collecting hood 66 is provided, and a suction pipe 68. The hood carries sharpening means comprising a carborundum block 180 in a rotatable bush 178 carried by an arm 174 normally supported by a rest 182, but capable of swing about pivots 172, 166 to the position shown in dotted lines, for sharpening the stool. To position the block 180 at the right angle for engagement with the tool, the pivot 166 is supported by one arm 162 of an L-shaped member pivoted at 152 and adapted to be swung about this pivot to limits determined by the ends of a slot in the horizontal part of the L engaging a pin 158. On this pin is a wing nut for clamping the member when the block is in the out-of-way position. The preferred speed when sharpening is some 4,200 revolutions per minute, the operative speed when roughening being about 300 revolutions per minute.

Abstract: 555,688. Telephone transmission systems. STANDARD TELEPHONES & CABLES,Ltd. May 22, 1942, No. 6996. Convention date, March 26, 1941. [Class 40 (iv)] [Also in Group XL] A communication circuit is opened and closed by means of a cold cathode tube which when ionized by the application of anode potential from a bridged source provides a low impedance path for speech currents across its cathodes. Fig. 1 shows the application to a cord circuit with the cathodes 105, 106 interposed in one leg and the anode 107, battery 108 and a switch S in a bridge circuit, which may include a choke coil to exclude alternating current therefrom. The tube acts as a current limiter, since if the signal current at any time equals the total current that can flow in the anode current one cathode will lose all its current. Fig. 3 shows a symmetrical arrangement, while Fig. 5 shows a modification employing a tube with 3 cathodes for interconnecting 3 circuits. In Fig. 4, the battery 126 is supplemented by alternating current from an oscillator 127, and a trigger anode connected to a battery 133 is provided. All the three switches shown must be closed to ionize the tube. The tube is filled with gas such as neon, argon or helium at a pressure of a few millimetres to a few centimetres of mercury, and the cathodes may be arranged as shown in Figs. 6-9.

Filed: 1936-03-09
Abstract: 470,112. Vehicle wheels. BEYELER, H. March 9, 1936, No. 7083. [Class 144 (i)] A double wheel device for use on tractors comprises a land-wheel 8 with a ribbed rim 1 arranged to overhang the tyre of a road-wheel 2, the wheel 8 being constructed to provide an opening through which the road-wheel can be lowered, means being also provided for selectively driving either wheel from the axle 3. In the form shown in Fig. 1, a pinion 17 slidably-keyed on the axle 3, is adjusted by a hand lever 21 to engage an internal gear 16 on a casting 15 fixed to the land-wheel 8, or a similar gear 161 on a pinion 14 for driving the road-wheel through gears 12, 11, 13. The wheel 8 has a displaceable segment 26 secured by a throughbolt 27, the segment being removed when it is desired to lower the wheel 2 into roadcontact. Fig. 3 shows a modification in which the pinion 12 in the driving-gear of the roadwheel 2 may be locked to rotate with the pinion 32 fast on the axle 3 by a rod 35 operated by the cam-head 34 of a hand lever 33. With the lever in this position (shown in full lines), the land-wheel 8 is driven through the counter-shaft 10. When the lever is swung into the position shown in dotted lines, it engages a slot in a fixed bracket 38 so as to lock the land-wheel and free the pinion 12 for transmission of the drive to the road-wheel. Fig. 5 shows a modified form of land-wheel comprising a series of hinged sectors 39, 40 adapted to be opened (as shown) to provide the operating-clearance for the road-wheel 2.

Title: D/a converter for pcm
IPC: H03M1/12
Filed: 1975-02-20
Abstract: 1444216 Digital - to - analogue conversion STANDARD TELEPHONES & CABLES Ltd 20 Feb 1975 7157/75 Heading H3H An analogue output is derived from a P.C.M. signal by increasing its sampling rate in interpolator 1, converting only the most significant bits to a pulse density signal in a rate-multiplier 3, and low-pass filtering 4 to give the analogue output. Noise is reduced by feeding back the least significant bits through a filter 12. The filter may comprise one or more delays whose outputs are combined with different weighting factors: several examples are described, Figs. 4, 8, 10, 11, not shown. The interpolator may be simply a recirculating register, Fig. 6, not shown, for merely repeating each P.C.M. word, e.g. 32 times or may be a linear interpolator, Fig. 7, not shown. D-to-A converter 3 comprises a synchronous binary counter 5, Fig. 2, fed with fast clock pulses fc, binarily weighted frequencies being obtained at its outputs A, B, C, D which are gated by the 4 most significant bits of the interpolated P.C.M. signal to produce a pulse train E of mean density corresponding to these 4 bits.

Title: Automatic regulator using transductors or d.c. saturated inductances
IPC: G05F1/32
Filed: 1942-05-27
Abstract: 555,958. Automatic control systems for variable conditions. ALLMANA SVENSKA ELEKTRISKA AKTIEBOLAGET. May 27, 1942, No. 7169. Convention date, June 9, 1941. [Class 38 (iv)] Current; variables in general.-To obtain an anti-hunting action in an automatic regulator employing D.C. saturated inductances as amplifiers, with or without self-fed or reaction windings thereon, a voltage is induced in a winding on one or more inductances which temporarily restores equilibrium between the regulated quantity and its normal value. A saturating winding 22 may for example be fed by a current which is the difference between a constant direct current due to a saturated inductance 10 and a regulated current-representing the regulated quantity fed in at terminals 14. When the cascaded amplifiers 20, 30, 40 operate due to a change in the regulated quantity a voltage is induced in a winding, for example 45 on the amplifier 40, which is applied, for example, to a saturating winding 15 to cause a transient change in the aforesaid constant direct current and overcome the effect of the time constant of the amplifiers. The voltage may be otherwise applied for this purpose. Specifications 479,596, 479,834 and 479,990 are referred to.

Title: Improvements in or connected with friction clutches or couplings
IPC: F16D13/10
Filed: 1921-03-08
Abstract: 177,042. Taylor, L. March 8, 1921. Clutches, friction.- A friction clutch consists of a pulley a round which are friction bands c, c<1>, each fitted with lugs c<2>, c<3> connected with an adjusting-stud d and a cam e respectively, carried in an outer clutch half g. Clutching is effected by transmitting the movement of the sleeve k towards the clutch to the cam e, through the links j, h, thus binding the bands on the pulley a. Studs l in the clutch half g prevent excessive outward springing of the bands when unclutched. In a modification, each band is operated by a toothed pinion engaging teeth on one end of the band.
