Title: Improved method of making forms for intaglio printing
IPC: G03F3/10
Filed: 1925-07-17
Abstract: 238,860. Blecher, C. Aug. 20, 1924, [Convention date]. Photo-mechanical printing-surfaces; coloursensitive and like plates; bichromated colloid and like processes.-In making intaglio printing blocks for high-speed presses the diapositives used are made with suitable gradation and viewed on a white reflecting support. This facilitates inspection and any necessary retouching, as well as a shortening of the time of exposure for the pigment paper on to which the diapositives are printed. In order further to make use of negatives which would give plates of too hard a gradation for reflected light diapositives, the plates are saturated before exposure in a dye (e.g. tartrazine) which can be washed out during development. The described method of making the pigment paper is by emulsification (not the introduction in powder form) of monochromate or dichromate of lead within the gelatin, or by the introduction of barium sulphate, both in relatively sufficient quantities. For making the copy more easily visible on the copper plate, substances of blue or bluish-red tone and of as actinic a nature as possible should be introduced in small quantities.

Abstract: 1,255,112. Working at specified temperatures; making wheels; forging. IIT RESEARCH INSTITUTE. 17 April, 1970 [7 May, 1969], No. 18452/70. Headings B3A, B3H and B3V. Titanium and titanium alloy workpieces are forged by heated tools at a temperature in the range 1400‹ to 1950‹ F. and controlling the rate of deformation such that the exerted pressure does not exceed the yield strength of the tools at that temperature. The temperature of the tool is the same as or lower than that of the workpiece. The forging dies are made of nickel or cobalt superalloys. The titanium alloy may contain 6% aluminium, 6% vanadium, 2% tin, or 8% aluminium, 1% molybdenum, 1% vanadium, or 6% aluminium, 4% vanadium. These alloys exhibit sensitivity to strain rate, i.e. yield strength increases with strain rate, so the press rate in forging must be low, such as less than 10 inches per minute and may vary. The dies are heated by external induction coils and the work pieces lubricated by glass or graphite. The process may produce an aeroplane nose wheel.

Abstract: 689,953. Supply system for X-ray apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 9, 1951 [Sept. 7, 1950], No. 18771/51. Class 38 (iv). To smoothly and gradually increase the A.C. supply to the primary winding 9 of a H.T. transformer 8 supplying, through a rectifier arrangement 6, an X-ray tube 5, a saturable reactor 12 has A.C. windings 10 in the transformer primary circuit to initially reduce the voltage of the supply thereto. At rest, the reactor 12 has a high impedance as an electron discharge tube 22 in the circuit of the reactor D.C. saturating winding 20 is held non-conductive by a negative bias potential C - connected through contacts 24 of a timer relay 17 to the tube grid 23. This bias potential also charges a condenser 27 shunted between the tube grid 23 and its cathode 25 so that on starting up, when an " X-ray on '' switch 19 is closed to start the timer 18 which energizes the relay 17 to close the transformer supply circuit and open the bias potential supply circuit, the tube 22 becomes conductive, but only gradually due to the charge on condenser 27, which charge slowly dissipates through a resistor 26. Gradually the reactor is saturated by the D.C. supply B +, B - and its impedance drops until the full rated voltage is applied across the transformer primary winding 9.

Title: Improvements in and relating to counting means and their use for the control of railway and other track vehicles
IPC: B61L1/16
Filed: 1943-11-11
Abstract: 574,023. Railway signals. BOOT, J., and METROPOLITAN - VICKERS - GRS, Ltd. Nov. 11, 1943, No. 18782. [Class 105] [Also in Group XIX] Counting means, which may be applied to counting wheel axles entering or leaving a railway track section, comprises a toothed wheel 1 and at least three actuating members 10a, 11a, 21a movable in sequence transversely to the teeth to effect step by step rotation of the wheel in either direction according to the order of the sequence. The wheel may be replaced by a straight or arcuate rack mounted in guides. The wheel has 10 teeth and its movement is restrained by a pawl engaging a wheel with 30 teeth mounted on the same spindle as the wheel 1. A third wheel on the spindle is geared to a revolution counter. The arrangement of the actuating members relative to the wheel 1 is such that when the member 10a is located on a tooth space median the members 11a, 21a are displaced 1/3 tooth pitch in opposite directions from tooth space medians. The actuating members are fixed to pivoted armatures 10, 11, 21 of polar responsive electromagnets 5, 6 so that operation of the armatures against spring retention is dependent upon the direction of current supplied to the magnet windings. Energisation of the electromagnets is controlled by sets of wheel-operated trackswitches 31-34 and 41-44 constructed as described in Specification 574,022. The arrangement is such that operation of the initial switch in each set causes movement of the member 10a along a tooth space median so that no movement of the counting wheel occurs. Sequential movement of the remaining three switches in each set causes the counting wheel to move one tooth. Where the track section is shorter than the train a duplicate set of electromagnets and associated counting wheel is provided and the two counting spindles are geared to the revolution counter through differential gearing. A signal 56 controlling entry into the track section can only be operated when the counting wheel indicates the section is empty. The signal is freed by energisation of a locking device 55 the circuit to which is closed only when the track section is empty by a switch 51 adapted to be operated by a pin 52 on a wheel 53 on the counting spindle. An economy switch 58 in the circuit of the locking device is closed as soon as an effort to move the signal is made. Further control is exercised by a relay 54 with a pick-up circuit which is closed when the track is occupied, and a holding circuit including a switch formed by pivoted armature 20 and contact 59 and which is closed, due to energisation of electromagnet 6 through switches 33, 42 and battery 46, only when switches 33, 42 are in the position shown and therefore wheels are not entering or leaving the track section.
