Title: Improvements in and relating to the determination of the strength of paper, fabrics and the like
IPC: G01N3/30
Filed: 1920-05-06
Abstract: 162,191. Elmendorf, A., and Marx, R. May 6, 1920. Testing physical qualities of materials.-Relates to a process for determining the resistance to tearing of paper, cloth, &c. by measuring the work done in effecting the tear. The material to be tested is folded in a special way and is placed between the jaws of a special gripping- device, one form of which is shown in Fig. 3. A cord 18 is attached to one gripping-member 20, Fig. 1, and passes over a grooved wheel 16, a counterweight 30 being provided. The cord is fixed to the wheel so that it cannot slip round its circumference by means of a pin 19. The outer rim 2 of the wheel 16 is graduated in degrees. Integral with the wheel is the pendulumbar 4 carrying the pendulum 5, which is held in a slightly-adjustable elevated position from which it can easily be released by means of a screw 13 passing through the casing 12 and engaging a small hole 14 in the bottom of the pendulum. The angle to which the pendulum is moved to the left of the vertical is given by moving a pointer 8, mounted on the spindle of the wheel 16 so that it rotates therewith if unobstructed, from the zero position Z to the rigid stop 9. If the pendulum is then allowed to fall, it tears the fabric and swings a certain distance to the right of the vertical, the angle being given by the pointer 8, which is prevented from rotating with the wheel by the stop 9. The work done in effecting the tear is then a direct function of the difference between the original angle to the left and the second angle swung to the right. A modification in which the pendulum may be released from more widely varying heights is described.

Abstract: 682,858. Stringed musical instruments. BRYAN, J. M. May 8,.1951 [May 19, 1950], No. 12628/50. Class 88 (ii). In a harpsichord or like instrument, each plectrum G is carried on a tongue D, Figs. 4, 5, pivoted at E to a jack A. After the plectrum G has plucked its associated string H on the upward stroke, the tongue D is tilted by the engagement of a protuberance K with the upper jack rail B so that the plectrum G does not touch the vibrating string H on the return stroke. The tongue D is returned to its upright position by the engagement of the rail B with a ramp L on the opposite side of the tongue from K. A damper J is held in a groove in the jack A by a spring clip N. A silent return of the plectrum to its rest position may be achieved also by the use of a modified form of damper J, Fig. 7, which is fitted beneath the plectrum G in order to damp the vibrations of the string during the return stroke and may be used in association with a jack of normal type. In a further alternative construction, Fig. 9, the plectrum G is fixed in the jack A which is tilted to avoid the vibrating string H on the return stroke by means of projections K which engage the upper jack rail B. In this construction the dampers are separate from the jacks and a sustaining pedal may be provided.

Title: Improvements relating to the scanning circuit arrangements for television and like apparatus
Inventor: BULL ERIC WILLIAM
IPC: H03K4/16
Filed: 1949-05-14
Abstract: 669,419. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 18, 1950 [May 14, 1949], No. 12915/49. Class 40 (iii). [Also in Group XL (c)] In a scanning circuit for television or like apparatus which comprises both a frame and a line scanning circuit, spurious voltages at line frequency which are induced at the electrodes of the valves in the frame scanning circuit are prevented from causing distortion by connecting each electrode to the respective cathode by an impedance which is of low value at line frequency but which has a substantial impedance at frame frequency. The Figure shows a television receiver in which incoming signals are amplified in unit 2 the synchronizing signals separated in unit 5 and applied to synchronize a line scanning circuit 6. The frame synchronizing signals are separated in unit 8 and applied via a winding 9 on a transformer 10 of a line time-base circuit of the type described in Specification 655,722, [Group XL (c)], which comprises a capacitor 12 which is charged from the H.T. supply via resistor 14 and periodically discharged by valve 11 which functions as a blocking oscillator by means of the transformer coupling 10 between the screen and control grids. The saw-tooth voltage developed across capacitor 12 is amplified in unit 15 and applied to the frame deflecting coils 16. Spurious voltage at line frequency which if induced at the screen or control grids would intermodulate with the frame frequency voltages during the periods when the valve is operating non-linearly and thus prevent correct interlacing, are filtered out by capacitors 17 and 18 connected directly to cathode. The capacitors are such that they present an impedance which is small compared with the input impedance at the respective electrodes at line frequency but present a substantial impedance at frame frequency. Specification 629,898, [Group XL (c)], also is referred to.

Title: Improvements in or relating to electric switches employing a conducting liquid
IPC: H01H29/20
Filed: 1935-05-02
Abstract: 449,426. Mercury switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and COX, W. R., and GIBSON, J. W., c/o General Electric Co., Ltd., Witton, Birmingham. May 2, 1935, No. 13100. [Class 38 (v)] A mercury switch comprises three vertical limbs 1, 2, 3 joined by horizontal limbs 4, 5, the limb 4 being formed with a construction 8. In the normal position shown, mercury connects contacts 6, 9 and if the switch is rocked fairly rapidly contact is made and broken at contact 6 due to movement of mercury in limbs 2 and 3. If the normal position is one in which the limbs are not vertical, mercury flows to or from limb 1 through constriction 8 and the level of the mercury relative to the contact 6 is unchanged and the operation of the switch due to rapid rocking is unaffected. The switch is used in sea fishing for controlling a flashing light on a marking float, the switch being operated by the rocking of the float, and is not rendered inoperative if the float takes a permanent list.
