A method of preparing a master print from an original circuit diagram, as disclosed in Specification 1,145, 242, is modified so as to employ as the light-sensitive plate or film an insulating board having a layer of conducting material and coated with a light-sensitive resist material. After silhouettes of the programmed track elements have been exposed on the resist material, the surface is developed and fixed and the circuit track pattern is etched out of the layer of the conducting material by immersion in an acid solution. In a continuous process for producing completed printed circuits a copper coated board is placed on a conveyer which carries it through preparatory washing and drying stages to a tank containing a photo-sensitive resist solution. The board is placed in the exposure plane of a photocomposing machine and then removed to another conveyer which carries the board through the remaining dipping operations to produce a finished printed circuit board.

Filed: 1962-05-09
Abstract: 987,471. Electric insulation. LEYBOLD-ANLAGEN HOLDING A.G. May 9, 1962, No. 17798/ 62. Heading D1P. [Also in Division H1] The Specification is concerned with maintaining a cable passing between an impregnating tank and a sheathing machine in the impregnant. Initially, an adaptor plug 6 is attached to the cable conductor by conical clamping members 12. This plug carries sealing rings on its periphery which fit tightly in a sealing member 7 at the outlet of the impregnating tank. The reel of cable is in the tabk which is first evacuated while the cable is heated by a current passed through its core by way of the adaptor plug 6. When the vacuum drying process is complete, impregnating oil fills the tank. An intermediate lock 20 is now inserted between the outlet of the tank and the entry 30 of the sheathing device. This latter entry is sealed by a pulling device 29 which is attached to the adaptor plug by a hauling rope 17. The lock is then evacuated and filled with impregnant. The process can be watched through an observation window 27. Next a manipulating window 26 is opened and the pulling device is fed to the sheathing machine which covers it with a sheath and tightens rope 17 to withdraw adaptor plug 6 from sealing plug 7. The whole cable is then sheathed and fed to drum 44. The pulling device 29 contains a piston connected to the rope 17 and a damping spring 39.

Abstract: 597,690. Reciprocating-pumps. BENDIX AVIATION CORPORATION. Sept. 20, 1944, No. 17980. Convention date, Sept. 2, 1943. [Class 102 (i)] [Also in Group XXVI] A regulating means for limiting the delivery of a pump when the delivery pressure exceeds a predetermined value, comprises a delivery chamber with a movable wall, the latter carrying the delivery valve and being acted on by the pump pressure to move against the action of a spring to provide free communication between the delivery chamber and the pumping chamber when the pressure exceeds the predetermined value. A double-acting pump comprises a piston 124 reciprocated by an eccentric portion 130 of the driving shaft which engages with a cylindrical member 132. Liquid enters an annular groove 158 in the piston 124 and passes through passages 160 to a chamber 162 and thence through an inlet valve 164 to a working chamber 210. One Wall of the chamber 210 is comprised by an outlet valve 174 having a flange 176 which seats on an annular gasket 178 which may be of fibre or neoprene. A diaphragm 180 is secured to the outlet valve by a rivet 182 and is clamped at its outer circumference between the main pump body and a cap 190. The outlet valve is closed by a spring 194. The chamber 192 between the cap 190 and the diaphragm 180 may be at atmospheric or supercharger pressure. After passing through the outlet valve to a chamber 188, liquid is discharged through passage 198 to an outlet 200. When the rate of flow is below the maximum, the outlet valve oscillates to and fro to accommodate the difference between the pump displacement and the volume of flow. The outlet valve may be byepassed by a passage 204 provided with a spring-pressed ball' valve 206 adapted to open at a lower pressure than the outlet valve in order to facilitate the escape of air at starting. Any liquid which escapes through the shaft seal 148 may be drained off through an outlet 150.

The oxygen is received through a control valve 12 and passes out through pipes 26 and 8 to the interior of the cot. Additional oxygen may be supplied to the cot through a valve 5 and choke tube 7, the rate of flow being indicated by a gauge 6. The apparatus may also be provided with a suction bottle 31 which is evacuated by an extractor 29 also operated by the compressed gas.

Abstract: 1466526 Rotary furnaces TSENTRAL NI INST TEKHNOL MASHINOSTR 1 May 1975 18162/75 Heading F4B In a plant for chromizing metal articles comprising an electrically heated furnace 2 tiltable about a transverse axis by means of gear 5, and a rotatable retort disposed within the furnace and including a working chamber 7 and an auxiliary chamber 8 communicating with each other through a throat 9, the arbitrary passage of granular chromium-containing material between the chambers 7 and 8 is prevented by means of a device 10 in the form of a multiple threaded screw located in the throat 9 and a partition 11 mounted in front of the screw on the working chamber side. The partition is provided with holes 12 of a size such as to permit the passage of grains of chromium-containing material but to prevent the passage of articles to be treated. The device 10 is fixed in a sleeve 13 one end of which bears against an annular collar 15 in the retort throat 9. Coaxially disposed tubes 16 and 17 are provided for supplying inert gas and process gas to the chambers 8 and 7 respectively. The ends of the retort 6 are closed by sealing covers 21 and 22. Cover 21 has two tubes 27 and 28 passing therethrough, the tube 28 serving for discharge of gaseous products from chamber 7 and tube 27 serving for the introduction during the chromizing process of a capsule 29 containing reagents such as halogen or halide. The retort 6 is rotated by means of a reversible drive 20. Chromizing may be carried out in various gaseous atmospheres such as natural gas, dissociated ammonia gas or inert gas such as argon. The retort may be tilted either upwardly or downwardly at an angle of 30 degrees or 45 degrees to the horizontal via the gear 5 (see Figs. 6-14, not shown), to facilitate (a) charging of granular chromiumcontaining material and of the articles to be coated, (b) transfer of the granular material to the working chamber when chromizing is to be effected and transfer back into the auxiliary chamber after chromizing of the articles, and (c) discharging of the chromized articles. The chromizing process itself is effected with the retort in a horizontal position. Transfer of the granular material from chamber 8 to chamber 7 is achieved with the retort rotated in one direction (see Fig. 11) and transfer of the material back into the auxiliary chamber 8 (after chromizing) is achieved with the retort rotated in the opposite sense (see Fig. 13).

Fig. 1 shows the transformer used as a coupling between a valve 1 energized from a master oscillator through amplifiers, frequency multipliers, &c., and a power valve 2 feeding an antenna. The primary 11 of the transformer is connected in the anode circuit of the valve 1 and forms in conjunction with a condenser 6 an oscillatory circuit tuned to the input frequency of the valve or a harmonic thereof. The secondary 12 of the transformer is connected to the grid circuit of the valve 2 through a biassing battery 19. Any electrostatic effect that may exist between the windings 11, 12 is augmented by condensers 20, 21 connected between the windings at opposite ends. The Specification as open to inspection under Sect. 91 (3) (a) states that the concentric form of winding may be replaced by two conductors in the form of straps secured together by insulation. This subject-matter does not appear in the Specification as accepted.
