Title: Rochelle salt piezoelectric crystal apparatus
IPC: H03H9/17
Filed: 1942-07-24
Abstract: 554,963. Piezo-electric crystals. STANDARD TELEPHONES & CABLES, Ltd. July 24, 1942, No. 10370. Convention date, June 10, 1941. [Class 40 (v)] A Rochelle salt crystal arranged for double resonance in the first and second shear thickness modes is cut with one pair of edges of a major face parallel to one of the crystal axis, the plane of the major face dividing the angle between the other two axes, and the ratio of length to thickness lying between 12 and 30. Fig. 1 shows a plate 1 of Rochelle salt with its major dimension L parallel to the X-axis of the natural crystal and the major plane at an angle of 45 degrees to the Y and Z axes. Similar plates are described in which the length dimension is parallel to the Y and Z axes. With these orientations, the first and second thickness shear modes of vibration are substantially uncoupled and are nearly of the same frequency when the ratio of length L to thickness T is in the range of 20 to 30. This enables the two modes to be used simultaneously for example in the filter circuits shown in Specifications 531,662 and 542,452. With a pair of electrodes on each face as 10 to 13, Fig. 5, the first thickness shear mode is generated when the polarities of adjacent electrodes are the same, while the second thickness mode results when adjacent electrodes have opposite polarity. The crystal may be mounted by suspension or clamping at its four corners. The relative impedance of the two modes can be varied by varying the angle of the line of division between the electrodes. Specifications 532,925, 533,204 and 553,457 also are referred to.

Title: Improvements in processes of bleaching cellulosic textile materials
IPC: D06L4/24
Filed: 1942-07-24
Abstract: Cellulosic textile materials are bleached by treatment with an alkaline solution of an alkali metal chlorite, e.g. sodium chlorite and a hypochlorite, e.g. sodium or calcium hypochlorite. The solution advantageoysly contains 1 to 3 grams of available chlorine per litre, the ratio of hypochlorite to chlorite being preferably about 1.5 to 1, based on the available chlorine and the preferred pH value of the solution being between 8.7 and 10.0. The process described and claimed in Specification 519,522, wherein chlorine is introduced into a chlorite bleaching liquor, is disclaimed.  The required pH value may be obtained by addition of sodium carbonate and/or bicarbonate. The material to be bleached is advantageously subjected to a preliminary kier-boiling followed by washing, souring with sulphuric acid or aqueous sulphur dioxide and again washing, and, after treatment with the bleaching solution, the material is squeezed, washed, soured, e.g. with aqueous sulphur dioxide, washed and finished.  Various examples of the bleaching process, employing temperatures up to 80 DEG  F. are given.

Title: Means controlling tension in a travelling web during drawing from a reel and re-reeling
Inventor: HUMPHREY ARTHUR WILLIAM
IPC: B65H23/06
Filed: 1966-03-10
Abstract: 1,171,641. Feeding webs. TIMSONS Ltd. 22 Feb., 1967 [10 March, 1966], No. 10477/66. Heading B8R. A brake band acting on a web-roll spindle, as described in Specification 1,046,803, is controlled by a fluid pressure system, which includes a dancer roller assembly pivoted to a shaft 3 and biased against the web tension by a fluid cylinder system 4, 5, 6. The datum pressure, equivalent to the required web tension, is governed by a valve 11. During normal web feeding, a valve 16 controlled by a cam 20 fixed to the shaft 3, governs the fluid pressure applied to a diaphragm 19 which is arranged to influence the web-roll brake and thereby control web tension. When the web feed is to be stopped, a normally closed, solenoid-operated valve 24 is opened, and maximum fluid pressure from the source 8 is applied to the diaphragm 19. However, application of maximum pressure for any length of time tends to cause excessive web tension and snatching. Therefore, means is provided to relieve the fluid pressure as soon as the web is tensioned to a predetermined amount. This means comprises a normally closed, solenoid-operated valve 26 which is opened simultaneously with valve 24. A valve 27 controlled by a cam 28 on the shaft 3, relieves the pressure when a predetermined web-tension is reached by way of a restrictor valve 29. The diaphragm may be used to control a re-wind drive such as that which includes an electric re-wind motor with torque varying switches or movable brush gear. Reference has been directed by the Comptroller to Specification 1,046,803.

Title: Improvements in or relating to transmission gears for driving airscrews
IPC: B64D35/04
Filed: 1941-08-19
Abstract: 551,411. Toothed gearing; driving airs crews. BOWER, G. S., CORBITT, R. W., and CUSHING, C. A. Aug. 19, 1941, No. 10565. [Class 80 (i)] [Also in Group XXXIII] Consists in gearing for driving a pair of airscrews in opposite directions' by two crankshafts which may form part of a single engine, The crankshafts may rotate in the same direction or in opposite directions. Two crankshafts 10, 11 rotate in the same direction and drive two co-axial shafts 12, 23 to which the airscrews 13, 22 are respectively secured The crankshafts have gear wheels 14, 15 secured on them and these drive wheels 16, 17 on the shafts 12, 23 through gear trains arranged as follows. The first train comprises co-axial wheels 18a, 18b connected by a torsionally flexible shaft 18c, and a wheel 18d which meshes with the wheels 18b and 16. The second train comprises a wheel 19a meshing with the wheel 14 and connected by a torsionally flexible shaft 19c with a wheel 19b which meshes with the wheel 17. The third and fourth trains 20a ... 20d and 21a ... 21c are respectively similar to and placed diametrically opposite the first and second trains, thus balancing bearing loads and tooth pressures on the wheels 14 ... 17. Thus, two trains are similar to one another, have each an even number of gears and are arranged symmetrically to drive one driven wheel and to be driven each by a different one of the crankshafts, while the other two trains are similar to one another, have each an odd number of gears and are arranged symmetrically to drive the other driven wheel and to be driven each by a different one of the crankshafts. In a modification, the airscrews are driven from crankshafts rotating in opposite directions by providing the train that drives one driven wheel from one crankshaft and the train that drives the other driven wheel from the other crankshaft with an even number of gears, and the other two trains with an odd number of gears and by providing greater torsional flexibility in the trains containing the fewer number of gears than in the other two trains. Specification 551,406, [Group XXVII], is referred to.

Abstract: 1,236,727. Hydraulic transmission of power. MOTOREN - UND TURBINEN - UNION FRIEDRICHSHAFEN G.m.b.H. 6 March, 1970 [8 March, 1969], No. 10852/70. Heading F2C. In an hydrodynamic transmission system, e.g. for railway locomotives, comprising at least one torque converter 15 for a lower speed range and at least one torque converter 16 for a higher speed range, the power input to the transmission is maintained substantially constant by providing the, or each, low speed torque converter with a centrifugal through-flow turbine, and the, or each, high speed torque converter with a centripetal or axial throughflow turbine. Increasing speed of the high speed turbines does not therefore increase the fluid circulation since only in the centrifugal throughflow turbines does increasing centrifugal force act on the fluid to increase its flow. As shown, the pumps 23, 27 are driven from input shaft 17 through gears 18, 19 and are mounted on a hollow shaft 20 directly and via a rotating housing 26 respectively. The turbines 24, 28 are mounted directly on a shaft 25 passing through the pump shaft 20. Again, the pump 27 may be mounted directly on the shaft 20, and the turbine 28 mounted on the turbine shaft 25 via a rotary housing.
