Abstract: 637,332. Blasting charges. COOK, J. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 6, 1947, No. 26791. [Class 9 (i)] [Also in Group XXII] A composite explosive charge giving a plane detonation wave-front and used to transfer a design from a stencil to a metal plate has a conical core with a plane base, the curved surface of the cone being covered by a uniform layer of explosive of higher detonation velocity than the core, the sine of the base angle of the cone being equal to the quotient of the detonation velocities of the two explosives. A cardboard container 3 with a base 6 contains a composite explosive charge over a cylindrical charge 5<SP>2</SP>, the composite charge being a conical charge 51 covered by a charge 5 of uniform thickness, the respective detonation velocities being 3600, 2300 and 5800 ms. per sec. and the base angle of the cone 23 22<SP>1</SP>. On firing the composite charge by an electric detonator 12 in a tetryl primer 11, a plane detonation wavefront is set up, so that a design on a hard cardboard stencil 1 will be embossed on a brass plate 8 without distortion. Partitions 4, 41 of stiff paper cover the conical surfaces and cushioning material 9 is placed between the brass plate and a steel anvil 10. The composite charge may be truncated towards the base by a surface or surfaces perpendicular to the base. The cylindrical charge may be an 80: 20 mixture of trinitrotoluene and sodium chloride, while the core of the conical charge may be a commercial powder and the outer thickness cyclotrimethylene trinitramine.

An imagewise exposed water-soluble silver salt print-out emulsion layer is contacted under pressure in the presence of water with an imagereceiving layer containing a reducing agent with or without reduction nuclei, whereby the silver salt in the unexposed portions of the emulsion is transferred to the receiving layer and therein converted into a positive silver image. In Example I a print-out emulsion, for which a mixing is quoted, is mixed with a silver chloride emulsion, saponin and potassium chrome alum and the mixture is coated on film and the coating is exposed for 7 minutes at 200 foot-candles through a letter, rolled through a bath in contact with a baryta subbed paper which had been treated with ascorbic acid and stripped therefrom to leave a positive lightblack image of the letters on an off-white background on the paper receiving layer. Thirteen succeeding examples follow the procedure of Example I with use of different image receiving layers, which latter include coatings with organic sulphur-containing materials, manganous acetate, silica, titanium and zinc oxides, zinc sulphide, colloidal silver and other substances ; and then Example XV, the last, presents further print-out emulsion mixings for the purpose.

Abstract: 1319483 Sample transfer apparatus BODENSEEWERK PERKIN-ELMER & CO GmbH 8 June 1970 [9 June 1969] 27633/70 Heading B1X [Also in Divisions F1 and F2] Apparatus which enables transfer of samples from containers 10, 12, 14, 16, Fig. 1 to analysis cells 18, 20, 22, 24 comprises, in the Fig. 1 embodiment a hose pump 46, vacuum source 58 and "squeeze type" valve 56. After rinsing with the sample by means of suction applied from source 58 the valve 56 is closed, by means of its co-operating action with the hose pump whilst the hose pump sucks sample to the cells. The pump is stopped whilst analysis e.g. photometry is carried out. The squeeze valve 56 is then opened so that the sample is sucked to waste reservoir 26 by the vacuum pump 58. Suction is developed in the hose pump by means of rotating compression heads 66 squeezing the lines 38, 40, 42, 44 with the pump housing 60 (see also Divisions Fl and F2). In the Figure 7 embodiment the valve action is performed by compression head 106 squeezing the line 108 internally of the pump cylinder 102. The vacuum pump 112 has effect when the head 106 is in position "a". Sample is drawn directly into conduit 98 from the container 96 when the head moves from position "a" to position "b". On the partial return stroke to position "c" the sample is passed back into cell 86. The next forward movement of the head 106 to position "a" brings the suction pump 112 into operation to transfer the sample to waste reservoir 110.

Abstract: 1,094,249. Data transmission systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 23. 1966 [July 6, 1965], No. 28028/66. Heading H4P. To prevent faulty operation of a frequencyshift binary data receiver upon abrupt termination of the receiver input, means is provided for detecting the termination which resets to all-zero the stages of a shift register through which the demodulated data passes to the recorder. In the transceiver described, when in transmission mode the transmitter transmits one or other of the shift frequencies when no data is being sent. In the receiving mode, parallel data from the shift register passes to the recorder via one or more stores which buffer the recorder against data at excessive input speed. Read-out from the store is prevented if an error-check reveals an error. When switching from reception mode to transmission mode, transmission is delayed for a fixed period to allow the distant receivers time to clear their shift registers.

Abstract: 1,207,099. Control of A.C. motors. BENDIX CORP. 3 June, 1969 [11 June, 1968], No. 28086/69. Heading H2J. A synchro transmitter 12 is connected to a follow-up synchro 13 whose rotor winding 44 is connected through amplifier 58 to the variable phase control winding 64 of a two-phase servo-- motor 66, a feedback resistor 68 increasing the gain of the amplifier 58. A fixed phase motor winding 70 is connected to power network 77, the motor being coupled to the rotor of the follow-up synchro through reduction gearing 87. The network 77 operates to reduce the power consumption at or near the null position of the servomotor by decreasing the excitation of the winding 70 to a predetermined minimum value. When the null position is approached, the gating control of rectifiers 100, 102 is determined by timing circuits 152, 154, comprising capacitors 168, 158, which are charged during alternate half-cycles of the voltage of source 26 until the potential thereacross becomes sufficient to render the associated rectifier conductive. Resistors 170, 171 allow quick discharge of the capacitors at the end of the charging half-wave. When the voltage applied to the winding 64 exceeds the dead-band range provided by zener diodes 184, 192, a transformer 179 end diodes 104, 106 become effective to trigger the rectifiers 100, 102. The firing points of the rectifiers are advanced to increase the portions of the half-waves applied to the winding 70. In a modification, the zener diodes 184, 192 are replaced by a zener diode connected in the lead 218, Fig. 2 (not shown).
