Title: Method of and means for the transmission of mechanical power
IPC: B06B3/00
Filed: 1924-01-31
Abstract: 237,934. Schieferstein, G. H. Jan. 31, 1924. Addition to 188,633. Machinery, utilizing inertia to obtain movements m.-In a method of and means for the transmission of mechanical energy in oscillating form as set forth in the parent Specification, the elastic intermediate member is replaced by alternative types of couplings adapted to transmit energy to the oscillatory driven system without substantially interfering with the oscillations or periodicity thereof. A direct drive may be transmitted from a crank or eccentric g, Fig. 2, to the end of one of the springs b which constrain the oscillations of the mass a and determine its periodicity. In a modification the crank acts through an elastic lever connected to an intermediate part of one of the springs b. The couplings may comprise an inertia member in the form of a weight k, Fig. 3, attached to a rod e suspended from the mass a, the oscillations imparted to the weight and rod by the crank g being gradually absorbed by the mass a moving with increasing amplitude. In the form shown in Fig. 5, the crank acts through an arm k engaging the mass a frictionally and offering a regulable resistance to movement about the pivot d so that energy is transmitted thereby to the mass but slip is allowed as the amplitude of oscillation increases and becomes greater than the crank stroke. The frictional connection mav be replaced by a ratchet connection as shown in Fig. 6. The various arrangements are adjustable and may be used in combination with an elastic coupling. In all the arrangements it is necessary that the speed of the driving mechanism should correspond substantially to the natural frequency of the oscillatory driven system. Reference has been directed by the Comptroller to Specifications 1213/79; and 146,436, [Class 102 (ii), Water &c., Raising &c.].

Title: Method of producing a Flexible Protective Tube for a Flexible Shaft
IPC: F16C1/26
Filed: 1968-01-19
Abstract: 1,166,773. Making flexible tubes. V.D.O. TACHOMETER WERKE, ADOLF SCHINDLING G.m.b.H., and H. T. GOLDE G.m.b.H. 19 Jan., 1968 [2 Feb., 1967], No. 3016/68. Addition to 1,091,066. Heading B3A. [Also in Divisions B6 and F2] A method of producing a flexible protective tube for a shaft guided in the tube, the latter comprising a wire helix 4 and having internally a brush-like layer 3, comprises first applying a layer 2 of adhesive to the wire which is to form the helix, then applying the brush-like layer 3 consisting of a plurality of short fibres or flakes, e.g. of abrasion-resistant plastics material, on to the adhesive layer 3 by electrostatic flocking and, after the adhesive has set, shaping the fibre-coated wire to form the wire helix of the protective tube with a brush-like layer inside the tube.

Title: Improvements in or relating to the manufacture of rayon yarn of varying denier
IPC: D01D5/20
Filed: 1937-02-02
Abstract: <PICT:0489714/IV/1> <PICT:0489714/IV/2> Rayon yarn of varying denier is made by passing the filaments from the spinning nozzle round a godet roller which is driven from a continuously rotating shaft, automatic brake mechanism being provided for periodically checking or stopping the godet roller without affecting the rotation of the shaft.  In Fig. 1, the godet roller 6 is mounted loosely on a driven shaft 7 and a coiled spring 8 is attached at one end to a collar 9 fixed to the shaft 7 and at the other end to a stud 10 fixed to the godet roller 6.  A projection of the stud 10 impinges on a stationary check plate 11 at each revolution of the godet roller 6 thus periodically checking or stopping the godet roller 6.  In Fig. 3, the godet roller 15 is attached to a shaft 17 on which is mounted also a pulley 18 (not shown) which is rotated by means of the driven pulley 26 and the band 25.  The spring 24 tends to keep the band 25 taut, but with each revolution of the cam 22, the bracket 20 on which the shaft 17 is mounted is depressed, thus causing the band 25 to slacken and the pulley 18 to contact with the brake shoe 27. In this way the godet roller 15 is periodically checked or stopped.  Specification 321,762, [Class 2 (ii)], is referred to.

Title: Improvements in or relating to modulated carrier wave transmitters
IPC: H03C7/02
Filed: 1939-01-30
Abstract: 524,416. Modulating systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 30, 1939, No. 3154. Convention date, Jan. 29, 1938. [Class 40 (v)] A carrier is modulated by varying the effective impedance terminating an impedance inverting line coupled to the output of the carrier generator. The carrier source 1 is coupled by line 51 consisting of hollow copper tubes 3, 5, an odd number of quarter wavelengths long, to the antenna or other load 19. A second quarter wave line 55 is also connected across the load and is terminated by modulating valves 21, 23, whose cathodes form extensions of conductors 45, 47. The anodes 25, 27 are earthed and the grids 29, 31 are connected by inductance 43 which resonates with the grid anode capacities to produce a high impedance from grids to earth. Modulation from a source 41 in series with a bias from 61 is applied in phase to the grids. The bias 61 is so adjusted that in the unmodulated condition the impedance presented by the input of line 55 is substantially equal to the load impedance 19 and the total power is divided equally between 19 and the modulator valves. The heating current for the cathodes 33, 35 is obtained from a generator 13 and is fed through the inner conductors 15, 17, of quarter wave line 53 and line 55. The line 53 is terminated by a shorting bar 11 and presents a very high impedance across the load 19. The cathode heating current may alternatively be supplied through filters direct to the cathodes or may be introduced within quarter wave section 51 at the mid point of the coupling inductance. Due to the nature of the resonant grid circuits of the modulator valves the system favours high modulation frequencies and this may be used to compensate for the attenuating effects of associated amplifiers on the higher modulation frequencies. If line 51 is slightly detuned it presents a reactive impedance at its input whose magnitude depends upon the load impedance. This may then be arranged to compensate for undesired frequency modulation of the oscillator produced by variation of its load.

[Also in Division F2] A valve for limiting the discharge pressure from a pump includes a differential-area piston 4, Fig. 1a, having its smaller face 5 directly exposed to the discharge pressure at 3 and its larger face 7 contiguous with a space 9 connected to the discharge pressure by way of flow restricting means 10, part of the space 9 being separated from the piston by a diaphragm 13 and connected to the suction pressure at 2. After the pump has been started a valve 11, which may be electrically actuated from the pump motor windings, is closed so that a slow build up of pressure takes place on the larger face 7 through the restriction 10 to close the valve 4. If the valve 11, which may be a needle valve, is cracked open or by-passed by an adjustable orifice, pressure bleeds from the space 9 to regulate the discharge pressure. The diaphragm 13 facilitates starting by providing a body of fluid which can be displaced through a balance pipe 12 into the suction side of the pump so that the initial movement of the piston 4 is unimpeded. A loading weight 13' may be connected to the diaphragm as shown in Fig. 2 and the piston may have a spring-loaded ball relief valve 55 to relieve surges on its larger face. An adjustably spring-loaded pressure relief valve 16' may be used to control the pressure in the space 9 and the closure member of this valve may consist of a piston loaded by an internal spring and having an orifice in its closure face. The piston 4 may also be controlled by a diaphragm-actuated needle valve, the diaphragm being subjected to pressure or vacuum at a remote point.
