Abstract: 703,757. Forging. HANKE, W. Nov. 13, 1951 [Nov. 24, 1950], No 28733/50. Class 83 (4) In a method of heading, the portion 10<SP>1</SP> of the work 10 which projects from the work-holder 12 and is to be acted upon by the punch 14, is supported against lateral bending during the heading by supporting means 15 positively moved during the heading in a direction such as to cause the supporting means to progressively uncover the said portion whilst the punch is moving in the opposite direction, whereby the metal of said portion is expanded progressively as at 16 into the progressively increasing gap between the work-holder and the supporting means. The size and shape of the formed head 16 may be controlled by varying the speed of axial movement of the sleeve relative to the punch.

Title: Improvements in and relating to the drying of wire in apparatus for coating wire
IPC: B05D3/04
Filed: 1930-09-25
Abstract: 360,132. Coating with metal; cleaning metals. H U G H E S, R. M., 72, Cannon Street, London.- (Johnson Steel & Wire Co., Inc. ; Wiser Avenue, Worchester, Massachusetts, U.S.A.) Sept. 25, 1930, No. 28739. [Class 82 (ii).] In apparatus for coating wire with metal by chemical deposition in an aqueous coating solution the drying of the wire after passing through a liquid bath, e.g. an acid bath, a water bath or a coating bath, is effected by passing the wire over a roll and directing an air blast against the wire in a direction toward the roll just as it leaves the roll so that the air impinges on the roll and is deflected back against the underside of the wire. A wire 1 is wound from a spool 2 and passed successively through an acid bath 3, a washing bath 24, a coating bath 5, and a washing bath 6 and then through a drier 7 to a spool 8. On emerging from the bath 6 the wire passes over a grooved roll 9 and is acted on by an air jet from a nozzle 10 on a pipe 11, the nozzle being directed towards the roll. Similar rolls and nozzles are provided to dry the wire on emerging from the baths 3 and 24, the nozzles being supplied with compressed air from a supply pipe 18. The drier 7 consists of a bed of heated granular material, e.g. sand or gravel which dries and polishes the wire. The water in the bath 24 is agitated by compressed air introduced into the bottom of the bath through a perforated pipe 17 connected through a valve 28 with the supply pipe 18. On leaving the acid bath the wire may be passed over a mass of absorbent material to remove any loose deposit.

Class 112 [Also in Group XXXIV] A mattress-tufting needle, Fig. 1, of hollow cylindrical form, has a keyhole slot 12, 13 adjacent its pointed end 11, and is provided with a plunger 14 which is biased forwardly by a spring 15. When the tuft head is inserted in the slot, as described in the parent Specification, the plunger is moved rearwardly to compress the spring, whereby the tuft head is automatically ejected during the withdrawal stroke of the needle. In a modification, Fig. 2, a wide slot 18 of uniform width, equal in length to slot 12, 13, is provided adjacent the pointed end, and a narrower slot 19, which serves the same function as the portion 13, is formed in the end of a plunger 20. The latter is pushed forwardly, against the bias of a spring 21, to enable the tuft end to be engaged in slot 19, and is released for the withdrawal stroke of the needle, whereby the spring retracts the plunger to effect automatic ejection of the tuft end during said stroke. In a further modification, Fig. 7, adapted for repairing a puncture in a tubeless tyre (see Group XXXIV), a tubular shank 22 is provided with a handle 24 and formed with a pointed end 23 and with a keyhole slot 29, 30 adjacent the latter. A plunger 26 is pushed forwardly by a knob 27 to eject the end of a continuous length 28 of rubber from the slot. A further slot may be formed diametrically opposite the wider portion 29, and of the same size as the latter, in order to accommodate the domed head of a rubber plug.

Title: Improvements in the measurement of the modulation ratio of an amplitude modulated high frequency signal
IPC: G01R29/06
Filed: 1953-10-23
Abstract: 768,679. Modulation measurement. PAYNE, E. L. Oct. 25, 1954 [Oct. 23, 1953], No. 29267/53. Class 37. A circuit measuring the modulation ratio b/a of an amplitude modulated H.F. signal in which the carrier peak amplitude is a and the modulation peak amplitude is b, comprises a first detector connected to the input and having a low-pass filter or H.F. choke coil interposed between its output and a first resistance across which is developed a first signal proportional to the peak carrier amplitude; a second detector whose input is capacitatively coupled to the low-pass filter output and whose output is coupled to a second resistance across which is developed a second signal proportional to the peak modulation amplitude, and an electrostatic voltmeter switchably and alternatively connectible to indicate the peak signal across the first resistance and the arithmetic sum of the first and second signals. The modulated R.F. input is variably coupled over a tuned circuit CC (Fig. 1), and capacitance C to a half-wave rectifier V1 having a choke capacitance coupled load resistance R; the time constant of the rectifying circuit being large compared with the carrier period but small compared with the modulation period, and the modulation component is separated from the unidirectional voltage across R proportional to the unmodulated carrier peak, and applied over blocking capacitance C1 and shunt resistance R1 to a second half-wave rectifier V2. With change-over switch SR in the position shown (Fig. 3), the anode of V2 is earthed and the cathode is connected over load resistance R3 shunted by capacitance C3 for energization from the modulation voltage developed across load resistance R2 coupled to resistance R1 by capacitance C2. On rotation of the switch anticlockwise, the rectifier V2 is inverted (Fig. 4) so that the anode of V2 is connected directly to the junction of capacitance C1 and R1 while the cathode is earthed over resistance R2 shunted by capacitance C2. R1 is made equal to R3 so that the D.C. resistance of the rectifier circuit is the same in each switch position. An electrostatic voltmeter M is alternatively switchable to measure the unidirectional peak voltage across resistance R for an unmodulated carrier input and thereafter the unidirectional peak voltage plus the unidirectiinal rectified component proportional to the positive or negative modulation peaks arising across R2. It is shown that where the measured voltage with modulation is Em and without modulation is Eu, the modulation ratio = Em/Eu 1. The rectifier V1 is switchably disconnectible from its load resistance R so that meter M may be calibrated by the injection across resistance R of a polarized low-frequency alternating voltage, and the deflection of the meter from a standard reading for Eu may be calibrated to read modulation ratio direct.
