Title: Valve assembly
IPC: F16K31/08
Filed: 1971-03-05
Abstract: 1376902 Valves WESTINGHOUSE BRAKE & SIGNAL CO Ltd 4 Feb 1972 [5 March 1971] 6098/71 Heading F2V A valve assembly includes a valve 32 biased towards its seat 7 by resilient means 75 with a force which is adjustable by movement of member 55 in accordance with the strength of an electric signal received thereby, movement of member 55 being damped as by fluid 67. The member 55 is an electric coil located between the poles of a permanent magnet 50 and receiving a signal in the form of an electric current. The valve 32 is located at the end of a cantilevered leaf spring 72 and controls the pressure of fluid delivered to a chamber 12 via inlet 3, passage 21, filter 19 and passage 13, by allowing some of the fluid to exhaust to atmosphere through a foam plastics mass 80. The controlled-pressure fluid passes through passage 15 and raises a diaphragm 17, thereby opening a valve 23 and allowing pressure fluid from conduit 21 to flow through chamber 25 and passage 26 to outlet 4. Subsequent pressure build-up in outlet chamber 25 acting on seat 28 forces the latter downwardly to close the valve 23. Thereafter, variations in the electric current signal and consequent variations of the pressure in chamber 12, result either in opening of the valve 23 to increase the pressure in outlet chamber 25, or in opening of valve 27 to allow some of the pressure in outlet chamber 25 to be relieved through a vent passage 31. The seat 7 for valve 32 is formed by a member 9 adjustably screwed into valve body 1. For transportation of the valve assembly, the member 55 is raised until its upper end 70 abuts a seal 69.

Abstract: 1361283 Measuring fluid-flow electrically K D G INSTRUMENTS Ltd 5 May 1972 [5 March 1971] 6163/71 Heading G1N A fluid flowmeter includes a calibrated restriction orifice 2, and a differential pressure transducer 7 including primary and secondary windings energized from an oscillator 8, and from which the difference signal between the outputs of the secondary windings is derived at 11 and fed to a variable gain amplifier stage 19 and to a level sensing stage 20 which receives also a signal from a reference source 21 and which acts to increase the gain of the stage 19 when the input signal level from the transducer to it falls below a predetermined value, a signal on lead 22 indicating change of gain and the output signal from stage 19 (via D.C. amplifier 24) both being fed to indicating, measuring or control means responsive thereto. A thermally responsive member 13 provides temperature compensation for the difference signal at 11 and for a signal representing the sum of the outputs of the secondary windings and which sum is used to stabilize the output of the oscillator 8 by comparison at 17 with a reference valve 18.

Title: Shoe and method of making same
IPC: B29C45/14
Filed: 1972-02-10
Abstract: 1387285 Boots &c B M CAMERON 10 Feb 1972 [19 July 1971] 6373/72 Heading A3B A shoe e.g. for athletes comprises a sole 44 which is moulded to have an interface establishing a rotary connection between the sole and a ground engaging pad 46. The shoe is made by forming an upper 10 on a last, positioning the last with upper in a mould, injecting material into the mould to form the sole bonded to the upper, and forming in the sole a rotary connection for the ground engaging pad 46. In a preferred method, (Fig. 2) there is placed in the sole mould cavity a disc 18 whose upper surface and outer portions of the lower surface carry a releasing agent while the remainder of the lower surface carries a bonding agent. After injection of the sole material, the ground engaging pad below disc 18 is cut free from the surrounding sole material and the release agent ensures that the pad is rotatable in the sole. Disc 18 may be dispensed with. In a modified method (Fig. 4, not shown) a solid cylinder (28) is positioned against the central portion of the underside of the disc during injection so that when the shoe is removed, a ground engaging pad may be attached to the disc e.g. by screws and nuts. In a further modification, separate injection passages are provided for the sole cavity and the ground engaging pad cavity.

Title: Improvements in and relating to printing plates and methods for making the same
IPC: B41N1/12
Filed: 1937-03-04
Abstract: 482,016. Printing-surfaces. GUNDLACH AKT.-GES., E. March 4, 1937, No. 6497. Convention date, Feb. 1. [Class 100 (ii)] In the manufacture of printing-plates from matrices made of a thermo-setting synthetic resin such as a phenol-formaldehyde resin, the printing-plate is made of the same resin and a layer of rubber for effecting equalization in pressure when the impression is taken. The matrix is first coated with a thin layer of fat or oil, and the synthetic resin in powdered form is then applied. A layer of rubber of a thickness of half a millimetre is then applied, and a further layer of the resin also. The whole is then hardened under heat and pressure, the rubber becoming vulcanized during this process. The matrix may contain impressions from a printing-surface made up of various kinds of originals, e.g. original type, zinc etching, and autotype.

Title: An arrangement in the receiving end of transmission equipment that works according to the time division principle
IPC: H04J3/10
Filed: 1962-02-20
Abstract: 991,769. Multiplex pulse signalling. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb 20, 1962 [Feb. 20, 1961], No. 6630/62. Heading H4L Relates to a time division multiplex ampli tude modulated pulse communication system wherein means are provided for using a plurality of channels to transmit a signal having a bandwidth larger than that passed by a single channel, and for reducing distortion due to non- linearity in the amplitude/frequency relationship arising if pulses of relatively long duration are transmitted Fig. 1 shows the receiving end, channels 4, 5 and 6 being used in conjunction to transmit the wideband signal after prior con. version into time divided amplitude modulated pulses. The gates 12 are operated sequentially by pulses from a shift register 11 via pulseforming networks 13, the shift register being controlled by pulses over channel 23 from a pulse generator (not shown). Alternatively the shift register may be controlled by pulses derived from the combined signal at the outputs of gates 12, Fig. 2 (not shown). Fig. 3 shows the frequency spectrum of the combined output of the gates 12 where f sk  denotes the pulse repetition frequency for an individual channel, 3f sk  = f s  denotes the pulse repetition frequency using the channels 4, 5, 6 in combination and the highest frequency which may appear in the original input signal is denoted by f max , and therefore f s  = 2f max . The frequency spectrum includes the original frequency band 0 to f max  but in which the amplitude shows a discontinuity at frequency f sk  instead of a level output, and first harmonic f s  together with harmonics 2f s , 3f s  &c., each harmonic having upper and lower sidebands corresponding to the frequency range of the original input signal but also showing distortion at frequencies 2f sk , 4f sk , &c. The combined outputs of the gates 12 are supplied to a low-pass filter 27 selecting the band 0 to f max , Fig. 3, and also to a band-pass filter 26 selecting a sideband of one of the harmonics, e.g. the lower sideband of the frequency f s . The sideband is fed to a demodulator 25 together with a signal of frequency f s  derived from lead 29. The demodulated sideband has a characteristic which is the inverse of that of the signal selected by the filter 27 and the addition of the two signals at 24 produces a resultant voltage/frequency characteristic, Fig. 7, in which the distortion is largely removed. An attenuator 28 adjusts the relative amplitudes of the two signals and the resultant signal is passed through a low-pass filter 21 with an upper cut-off frequency f max  before amplification at 22.

Filed: 1920-03-09
Abstract: 164,819. Ryan, C. J., and Ryan, G. A. March 9, 1920. Periodic; applied by springs. - Relates to means for automatically stopping gramophones wherein a spring- operated plunger b engaging the turntable is retained in the off position by a spring-operated member h and released by the contact of the tone arm with a setting-rod o. According to the invention, the plunger b passes through a diametral hole in the releasing member h and is retained by the friction set up by the twist of a spring m. When the needle or tone arm engages the rod o, the member h is turned so as to remove the frictional restraint and release the brake plunger which is tapered to permit of a gradual application. In a modification, the spindle h is arranged horizontally and is turned by the action of a weighted arm, the tone arm engaging the weight which is adjustable along the arm.
