Title: Improvements in and relating to apparatus for finishing felt materials
IPC: D04H17/00
Filed: 1935-04-25
Abstract: 455,503. Hats. FARR, G. F., 58, Colling- don Street, Luton, Bedfordshire. April 25, 1935, No. 12457. [Class 63] [See also Group VIII] Finishing.-A felt finishing machine has a driven work-supporting roller 26 of substantially the same width as a reciprocating abrasive member 25, the roller being carried by a simple link system to approach or recede from the abrasive member under control of an operator. An electric motor drives a spindle 7 and, by a flexible shaft 27, the roller 26, the latter being driven slowly, and the driving speeds being variable. The shaft 7 carries an eccentric pin reciprocating a shaft 12 carrying a sleeve 15 to which is secured a block 19 carrying a rubber block 20. A strip of glass paper 25 is retained in position by a spring clip 24, the ends of which engage inclined grooves in the block 19. The roller is approached to and removed from the tool by a treadle 32. The circuit to the electric motor may be completed automatically as the roller 26 approaches the tool. A brush may be substituted for the tool shown.

Title: Improvements in or relating to circuits for automatically tuning the output circuitsof high-frequency oscillation generators
IPC: H05B6/50
Filed: 1952-05-19
Abstract: 706,242. Automatic tuning control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 19, 1952 [May 22, 1951], No. 12598/52. Class 38 (4) The load circuit 10 of a high frequency oscillator, used for example in medical treatment, is automatically maintained in resonance with the oscillator output by the use of two phase-comparing valves 3, 4, one input grid 5 of each valve receiving a fraction of the oscillatory voltage of the primary oscillatory circuit 7, and the other input grids 6 being connected to opposite ends of a coil 9 centre-tapped to earth and coupled to the load circuit 10. When the load circuit is in tune, the voltages on 5, 6 are in quadrature and result in equal voltages across the anode resistors 1, 2 ; the mis-tuning causes a departure in opposite directions from the quadrature relation giving a rise in voltage at one anode and a fall at the other. The rising voltage, applied to the grid of one of a pair of thyratrons 11, 12 causes ignition of that tube and current passes from an A.C. supply through the armature 21 and one or other of the field coils 13, 14 of a reversing motor which is geared to a tuning condenser 15, thus bringing the load circuit into tune with the oscillator. Stray fields are prevented or rendered ineffective by screening the high-frequency leads, the thyratrons 11, 12, and the phase-comparing valves 3, 4 which may be of the nonode type. The point of ignition of the thyratrons is adjustable by a potential-divider 16, and a common cathode resistor 19 prevents them from firing simultaneously. Variable cathode resistors 17, 18 permit initial balancing of the valves 3, 4. Operating current is supplied to the tubes by supply leads I ... VI.

Title: Improvements in or relating to means for raising submerged vessels
IPC: B63C7/12
Filed: 1919-03-03
Abstract: 150,365. Ryan, A. H. March 3, 1919. Sunken ships, raising. - A series of inflatable buoys a are secured along the sides of a submerged vessel by means of cables a<3> which pass through pockets a<2> formed along the upper and lower edges of the buoys, the latter being formed with a flat side to fit against the ship. The buoys are connected by air pipes c, and are preferably inflated from a forked supply pipe, one branch being connected to the port and the other to the starboard buoys. Each buoy is provided with a protective coating of chain mesh, or is enclosed by overlapping plates or staves g, Fig. 7, having inwardly and outwardly turned flanges g<2> which abut against each other in the expanded position. Eyes g<3> on each plate engage with pivoted rods h<1>, h<2>, which serve as guides during inflation and deflation. The protective means are preferably of aluminium or other light metal. Each buoy is provided with a non-return inlet-valve which may be a spring-pressed ball valve i, Fig. 8. Where a series of buoys is to be inflated from a common air pipe connexion, each buoy is also provided with an outlet valve which also consists of a spring- pressed ball valve j, Figs. 9 and 10. The valve j is normally held off its seat by sliding grids j<4> which are pulled towards each other by springs j<5> and pulled apart, as the buoy becomes inflated, by springs j<7>. The springs j<5> are made successively weaker in the buoys as they are further away from the air pump connexion, so as to prevent the buoys nearer the pump connexion from closing their outlets before the buoys further away are fully inflated. When the whole of the buoys are inflated and all the valves closed, the effects of any damage to a bouy are confined to that buoy, escape of air from the other buoys being prevented by the valves. Buoys may also be employed inside the sunken ship.

Title: Improvements in or relating to remote control systems
IPC: G05D3/14
Filed: 1957-04-25
Abstract: 831,551. Electric correspondence control systems. COLE Ltd., E. K., and COPPIN, K. J. July 22, 1958 [April 25, 1957], No. 13153/57. Class 40 (1). [Also in Group XXXVI] In an automatically balanced D.C. resistance bridge for e.g. positioning a tool relative to a workpiece, the master potentiometer comprises a series of tapped decade resistors preferably each fed from a separate source, so that only the unbalance current flows through the sliding contacts. To eliminate backlash final balance is always obtained by movement in the same direction, and to avoid hunting the supply to the servomotor is intermittently interrupted as balance is approached. As shown (Fig. 4) the master potentiometer of a bridge comprises a coarse tapped resistor P fed from winding S2 of a mains transformer, and five tapped resistors Q and R fed in series from a further winding S3 of the mains transformer. Each resistor P, Q, R consists of ten equal units, the value of the voltages from windings S2, S3 and the resistor elements being such that the voltage drops across the resistor elements are in decimal relationship, adjustments being effected by variable resistors Rx, Ry. Any difference between the voltage tapped off from resistors P; Q, R and that at the slider of slave potentiometer S energizes a polarized relay BR in the bridge diagonal to cause a servomotor M to drive the slider to a position of balance, simultaneously adjusting the position of a controlled element, not shown. The polarized relay BR also introduces an additional voltage into the bridge diagonal via resistor C and A or B, causing the motor to stop at an offset balance point and advance intermittently to the true balance position, the offset balance point being always on the same side of the true balance position so that the final movement is always in the same direction. The master potentiometer may be adjusted manually or by a punched card.

Filed: 1937-05-08
Abstract: 494,845. Winding apparatus, BELL, W T., and PERRY, F. B. May 8, 1937, No. 13191. [Class 78 (v)] In winding-mechanism for cages of the kind provided with means for restricting automatically the speed when the cage approaches the end of the wind at excessive speed, the appropriate one of two cams driven from the winding engine presses a piston into its cylinder near the end of each wind, and if this movement takes place at excessive speed, the flow of fluid from the cylinder through an orifice is restricted, with the result that the fluid passes into another cylinder and builds up sufficient pressure therein to cause the actuation of the control means of the engine. The cams 8a, 9a, Fig. 1, driven by the engine are engaged by rollers 21a at the ends of arms 21 fast on a shaft 18. An arm 17 on this shaft is connected by a link 16 to the piston 15 of a cylinder 12 arranged in a tank 11 containing oil. An orifice 23 in the cylinder is provided with a valve operated by an arm 23a which is connected by a link 16a to an arm 16b on the link 16. The size of the orifice is therefore reduced progressively as the cage approaches the end of its travel. An orifice 14 in the cylinder leads to a cylinder 13 containing a plunger 24, the rod 25 of which is connected to an arm 26 on a spindle 27 connected to the engine control gear. When the device is not required to function, a non-return valve 30 in the bottom of the cylinder 12 can be raised by a lever 32 and link 33. The device may be incorporated with the mechanism described in Specification 486,454. In a modification, Fig. 6, the piston 16, has apertures 35, and is made hollow' to receive a fixed tapering needle 34.
