Title: Process for tamping railway tracks and a movable machine for effecting the process
IPC: E01B27/16
Filed: 1975-12-18
Abstract: 1476260 Compaction testing; sound transmission MATISA MATERIAL INDUSTRIEL SA 18 Dec 1975 [17 Jan 1975] 51788/75 Heading G1G [Also in Division E1] A device for measuring and controlling the degree of compactness of railway track ballast comprises an accelerometer pick-up device 20 rigidly fixed on a feeler 21 which has a cylindrical roller which is maintained in non-elastic connection with a rail of the track, to measure the amplitude of vibrations retransmitted by the ballast from the tamping tools 7, 8 across the sleepers to the rail. The signal from the pick-up 20 is fed via a frequency filter 24 which transmits only those signals whose frequency corresponds to those of the vibration of the tamping tools 7, 8, to an averaging device 26 which records the mean amplitude over a certain number of vibrations, and to a differential device 27 which produces a signal which is proportional to the difference, A-a, between each measured amplitude, A, and the mean amplitude, a, determined by the averaging device 26. When the treated ballast approaches the desired maximal degree of compactness the amplitude of the vibrations will increase to a predetermined value, and this predetermined value, K, of the increase of the amplitude is fed. Together with the signal proportional to the difference, A-a, from the differential device 27, to a comparison device 28. The comparison device 28 then delivers a signal to stop the tamping operation when the difference, A-a, reaches the value, K.

Filed: 1964-12-22
Abstract: Copper cyanide plating baths include a phosphoric acid ester of a poly oxyethylenated alkyl phenol of formula <FORM:1066820/C6-C7/1> in which m = 0 or 1, n is 8 to 30, A is hydrogen or a solubilizing ion, R is an alkyl group of 4-14 C atoms, and R1 R2 are lower alkyl groups. In a range of examples, a preferred compound is the phosphate ester of nonyl phenol having an oxyethylene chain of 15(-C2H4O-) units.  The alkali cyanide copper bath may also include Rochelle salt, E.D.T.A., citrates, gluconates, and brighteners e.g. ammeline, rhodanine, and cyclic N compounds containing mercapto, alkyl-amino, or alkynylamino groups.  The base metal, which may be steel or zinc die castings, are first cleaned preferably with emulsions e.g. kerosene emulsified with petroleum sulphonate, or triethanolamine soap, rinsed and then plated at pH 11 to 13, with air agitation and pulsed D.C.

Title: Mounting sliders for sliding clasp fasteners
IPC: A44B19/26
Filed: 1974-12-03
Abstract: 1432330 A package for sliders for sliding- clasp-fasteners YOSHIDA KOGYO KK 3 Dec 1974 [11 Dec 1973] 52213/74 Heading B8C In a packaging arrangement for a plurality of sliders for sliding clasp fasteners a series of sliders 11 are individually, and removably, mounted in a row upon an elongate support member 10 each slider being adapted for eventual incorporation in a sliding clasp fastener after removal from the support member. As shown in Figs. 1, 2, sliders 11, each comprising a pair of interconnected, and spaced apart, wing, or plate, members, which define a generally Y- shaped guide channel through the slider body, but which can be practically any type, or configuration known in the art are mounted side-by-side astraddle the upper edge of a thin elongate strip 10 of material. Each slider should be easily removable, e.g. by finger pressure, from the strip 10 but, at the same time the sliders must not fall off the strip when the latter is inclined, or suspended, vertically. To meet these requirements the strip 10 can be made, e.g. of paper, plastics, rubber, etc., so that the sliders may resiliently engage thereon. Alternatively, interengageable projections and depressions may be formed on the support member 10 and the sliders 11. Other easily-releasable fastening means may comprise magnetic attraction, tackifier, or coagulator. When the sliders are made of plastics material their inherent resiliency may be used to fit them snugly on to the support members 10. A support member 10a, Figs. 3, 4, comprises a slender rod, e.g. a wire of synthetic resin monofilament. If the support member 10 is made of flexible, or pliant material it can be wound upon a reel 13, with sliders fitted thereto, Fig. 5. A support member, made of flexible material, may be folded in zigzag fashion and be accommodated in an opentop receptacle (16), Fig. 6, (not shown). If the support member is made of relatively rigid material then equal lengths thereof, each carrying a rows of sliders, can be stacked in a receptacle 17, Fig. 7, having a pair of openings 18 formed through the opposite side walls, at least one of the openings having a size sufficient to allow each support member 10 carrying a row of sliders 11, to pass therethrough when pushed by a rod 19 thrust into the other opening 18.

Title: Convergence Waveform Shaping Circuitry
IPC: H04N9/28

Abstract: 1,156,510. Cathode-ray tube circuits. SYLVANIA ELECTRIC PRODUCTS Inc. 23 Nov., 1966 [23 Dec., 1965], No. 52494/66. Heading H4T. In a convergence circuit for a three - beam colour television cathode-ray display tube a shaping circuit comprising a gated-type impedance is connected in series with at least one of the three convergence control windings to alter the rate of change of flow, during trace intervals, of the usual parabolic current waveform so that convergence is produced at positions intermediate the mid-point and each end of the trace without affecting the convergence at the mid-point and the ends. Thus, as shown in Fig. 4, the convergence windings 45, 47 (also Fig. 5, not shown) for controlling horizontal convergence of the green and red beams are each connected in series with respective gated impedances 85, 95 comprising resistors 87, 97, shunted by diodes 89, 99, the latter changing from the conductive state to the non-conductive state as the conventional sawtooth voltage waveform (produced in circuit 59 under the control of pulses from the horizontal deflection transformer 19) from which the parabolic current waveform is produced in windings 45, 47 approaches the centre of its forward stroke period so that resistors 87 and 97 become effectively connected in series with the respective windings 45, 47. The resulting voltage drop across resistors 87, 97 is thus effectively subtracted from the applied sawtooth and the resulting current waveform in windings 45, 47 is stated to effect convergence at the positions intermediate the sides and the mid-point whilst the convergence at the sides and the mid-point continues to be effected in known manner. The winding 49 for convergence control of the blue beam is not provided with a shaping circuit and the circuitry of Fig. 4 is repeated for vertical convergence control.

Abstract: 1325910 Television FERNSEH GmbH 6 Nov 1970 [7 Nov 1969] 52960/70 Heading H4F The invention seeks to prevent the production of streaks in a flying spot scanner due to the afterglow effect which causes the horizontal blanking level to vary, even after compensation in an RC network, by clamping each horizontal blanking interval to the vertical blanking level. In the embodiment illustrated the video signal is supplied to a transistor 1 acting as an impedance transformer, and then to a first clamping circuit comprising transistor 24, capacitors 3, 22 and resistors 23, 25, 26 which operates with pulses of the vertical blanking frequency. The signal then passes to a further impedance transformer comprising transistors 4, 6 and resistors 5, 7 where the blanking signal is mixed into the emitter of transistor 6 by means of transistors 9, 10, 13, capacitor 17 and resistors 8, 11, 12, 14- 16. Also connected to the emitter of transistor 6 is a second clamping circuit comprising transistors 18, 20 and resistors 19, 21 fed with a mixture of vertical and horizontal blanking pulses. Figs. 4 and 5 (not shown) illustrate modifications of this circuit.
