Title: An improvement in suspension means for heald shafts in looms
IPC: D03C1/14
Filed: 1948-06-18
Abstract: 661,387. Shedding mechanism. ZBROJOVKA BRNO, NARODNI PODNIK, June 18, 1948 [June 23, 1947], No. 16431/48. Class 142(i). Heald shafts are suspended on pulleys 8, 16 set at an angle to the shafts so that the shafts are positioned nearer to the slay. The pulleys rotate on bushes 27 secured on axles 23, 24 and bored obliquely. The lower pulleys 14, 21 are in line with the heald shafts. A heald shaft lever 1 is secured to a draw rod 4 and a steel rope 7 connects the rod 4 and a slat 10 pinned to one of the shafts. A pin 29 engaging one of a series of holes at the top of the slat and a pin 33 engaging a slot near the centre of the slat secure the slat to the heald shaft. A draw. rod 12 hooks into one of a series of holes in the lower end of the slat. A turnbuckle 17 is provided for adjustment of the length of the steel rope. Discs 39, 39<SP>1</SP> prevent the pulleys from shifting along the axles 23, 24.

Title: Improvements in amplifiers
IPC: H03B9/01
Filed: 1923-06-25
Abstract: 199,742. British Thomson-Houston Co., Ltd., (Assignees of Hennelly, E. F.). June 26, 1922, [Convention date]. Thermionic amplifiers and generators comprise a magnetically-controlled thermionic valve in which the polarizing field is opposed by the field produced by an additional winding carrying the output current. This results in greater amplification, the vertical part of the current-fieldstrength-characteristic being steeper than with the usual circuits. As shown the polarizing winding 5 also carries input currents from the transformer 7, 8. The output circuit includes the winding 12 for producing the opposing field and. the primary 10 of the output transformer. The secondary 11 may be connected to the input of a further amplifier.

Title: Device for the automatic delayed switching on or off of an amplifier or detector
IPC: G04C23/00
Filed: 1940-11-15
Abstract: 577,345. Valve circuits for wireless reception. WEIGHTON, D., and PYE, Ltd. Nov. 15, 1940, No. 16523. [Class 40 (v)] Delayed switching is obtained in a thermionic valve circuit by using a valve with two collector electrodes connected to a positive source and a controlling electrode connected by a condenser to one of the collector electrodes and to the cathode through a resistance. The Figure shows a pentode with the suppressor grid 15 used as the controlling electrode and coupled to the screen through condenser 3. In this way the condenser 3 is charged to the potential of the high tension source while the cathode is cold and after the cathode is operative the valve is inoperative until the condenser has discharged through resistance 4. As shown the rise of anode current will occur suddenly and the grid 15 become positive and draw electron current to discharge condenser so that the grid becomes negative and again renders the valve inoperative. The operative period will depend upon the value of resistance 5. If resistance 4 is returned to a potentiometer across the high tension source delayed switching without the subsequent -reversion to an inoperative condition may be obtained. With this arrangement adjustment of the potentiometer will give a further control of the time period. The valve may be one already existing in the apparatus and may be a high or low frequency amplifier or a detector which may constitute the only valve in the receiver. Impulses may be taken across resistance 7 for the switching of further apparatus.

Title: Hydraulic braking systems for vehicles

IPC: B60T11/24
Filed: 1963-04-29
Abstract: 981,176. Fluid-pressure brakes. ROLLSROYCE Ltd. April 29, 1963, No. 16843/63. Headings F2E and F2F. An hydraulic braking system for a vehicle comprises both power operated and master cylinder operated brakes associated with the same wheel or wheels, and a link structure connecting a valve control member of the power system and a push rod of the master cylinder piston to a common operating member for balanced operation and such that either system can operate alone if the other fails. As shown, a vehicle having front wheels 1 and rear wheels 3 is braked by three hydraulic systems, viz. a first power system comprising a reservoir 5, pump 7, accumulator 10, associated relief valve 9, valve 15 and brakes 1b 2b, a second power system comprising a reservoir 26, pump 24, accumulator 29, associated relief valve 28, valve 31 and brakes 1a, 2a, 3a, 4a, and a non-powered system comprising a master cylinder 35 and brakes 3b, 4b. The master cylinder together with its piston 36 is arranged as a telescopic link between a pedal 34 and a balance beam 33 the opposite ends of which act on the control rods 16, 32 of the valves, so that all three systems are normally actuated, pressure in the master cylinder system being obtained as a result of " feel " which acts rearwardly on each control rod and results from the pressure of fluid in the delivery pipe 17 from each valve to the brake cylinders being caused to act, via a passage 19, Fig. 2, on the forward end 21 of the control rod, augmented by the force of a spring 22. Each control rod has a reduced diameter portion 18 so that pipe 17 is thereby connected either with pressure supply line 14 or with return line 23 leading to the reservoir of the associated system, according to the position of the control rod, thus providing a self-lapping arrangement whereby brake pressure in line 17 is proportional to pedal pressure. If either of the power systems fails the appropriate control rod 16 or 32 moves to its forward limiting position on the application of force to the pedal, balance beam 33 taking up an inclined position in which it still acts on the other control rod. Braking is still obtained on all four wheels in either case but with increased pedal pressures. If both power systems fail braking is still obtained on the rear wheels only, after both control rods have moved to their forward limiting positions, by the master cylinder 35. Failure of the master cylinder system is catered for by an abutment 44 limiting telescoping of the cylinder and piston 36. In a modification (Fig. 3, not shown) the cylinder 35 is fixed and the balance beam 33 is pivoted on one end of a further balance beam which is linked to the pedal at an intermediate position and linked to the piston of the master cylinder at its opposite end.
