Title: Improvements in or relating to methods of etching
Inventor: YOUNG LAWRENCE JOHN
IPC: C25F3/14
Filed: 1964-02-27
Abstract: In making a plate having a raised pattern by electrolytically etching, a coating of resist corresponding to the required pattern is applied and the etching process is stopped before significant undercutting has taken place.  The newly formed sidewalls surrounding the etched areas are given a protective covering and further etching takes place as before so as to form a second sidewall.  The shoulder formed between the first and second sidewalls is removed in a final step.  A preferred bath contains a saturated solution of four parts of sodium chloride to one part of ammonium chloride.  Some of these salts may be left in the solution to ensure that the whole solution is fully saturated. The plate is held 1/2 " from a cathode and at room temperature a direct current of 10 amps per square inch is passed through the bath.  Etching is carried out in five minutes periods and the plate is examined at the end of each for flaws in the resist, which may be of resin or rubber.

Abstract: 944,697. Packaging-machines. ROSE BROS. (GAINSBOROUGH) Ltd. June 9, 1960 [March 11, 1959], No. 8325/59. Heading B8C. In a machine of the kind described in Specification 781,180, the cartons, in their passage beneath the filling hoppers, pass over rails one of which is agitated to settle the contents, the degree of agitation depending on the volume of material fed into the cartons so that uniformity of contents level may be achieved. One rail 173 is carried on a bell-crank 176 and is oscillated by a crank-pin 178 and lever 177. A motor 179 has with the crank-shaft a known belt connection which gives a speed variation according to variations in the distance between the crank-shaft and the motor driving shaft. The motor is pivoted at 182 and is tilted by an arm 183 having a connection with a sleeve 186, the latter being raised or lowered by rotation of the shaft 41 adjusting the volume of the hoppers 17. Thus the volume adjustment tilts the motor 179 to alter the rate of oscillation of the rail 173. The other rail 174 is on an arm pivoted at 187 and connected to the sleeve 186 by a link 188. Movement of the sleeve raises or lowers the rail 174, thus effecting the amplitude of oscillation of the cartons by the rail 173.

Abstract: 579,494. Belt fastenings. YATES. C. H., and SOUTHGATE, A. E. May 3, 1944, No. 8355. [Class 80 (i)] Each end of the belt has secured thereto a channel plate 1 the end plate 2 of which is concave outwards and has a number of equally spaced slots to receive parallel eyes 5 formed from a continuous wire, a common hinge-pin being passed through the intermeshed eyes. The wire is bent to form one U-shaped eye 5, is then continued to form a connecting bar 6 at right angles to a leg of the U for a distance equal to the pitch of the slots 4, another parallel eye is then formed and a further bar 6 on the other side and so on producing two sets of connecting bars 6, one set on each side. The eyes are pushed through slots 4, the bars 6 abutting the inner surface of the plate 2. The concavity 3 prevents the sets of bars 6 from approaching one another and therefore prevents the eyes closing together. After inserting the eyes a series of prongs 7 are stamped out of one or both walls 1 and turned inwards, thereby preventing the eyes from being pushed back.

Filed: 1975-02-28
Abstract: 1503017 Semiconductor devices TOKYO SHIBAURA ELECTRIC CO Ltd 28 Feb 1975 [28 Feb 1974 (2)] 8370/75 Heading H1K In a method of making a semiconductor device, e.g. complementary IGFET pairs, diffusion into a semiconductor substrate 1 is carried out from a doped oxide film 37 by heating the substrate to thereby also effect diffusion from a second source into another surface portion. A chemical vapour deposited layer 38 is formed over the oxide film 37 to prevent out-diffusion. In one variant of the method, the second diffusion source is a gas within the furnace used to heat the substrate. In other variants, the second diffusion source is also a doped oxide film or ions are implanted into the substrate surface. As shown, the oxide film diffusion source comprises a layer 37 of phosphosilicate glass covered with a layer 38 of SiO 2 . This results in N-type regions 3, 4, of an N channel IGFET and a guard ring 21. Boron oxide or nitride is admitted to the furnace and in-diffuses to form P-type regions 5, 6 of a P channel IGFET and a guard ring 22. Electrodes are deposited after standard etching processes have been used. When the second diffusion source is also a doped oxide film this too comprises a composite layer. Borosilicate glass and SiO 2  are deposited over the first diffusion source layer, the initial oxide mask 31 and over the substrate surface.

Abstract: 657,951. Condensers. BRITISH THOMSONHOUSTON CO., Ltd. March 30, 1949, No. 8659. Convention date, March 31, 1948. [Class 37] [Also in Group VIII] A tap strap 27 is inserted in a condenser from a long strip of mounting material 20 carrying several equally spaced straps 27 projecting laterally from an edge of the mounting strip 20 to which they are fixed, by feeding a free end of the strip 20 between and in frictional engagement with adjacent conducting and dielectric strips 23, 24 converging at a winding means to form a condenser so that the taps 27 are transverse to these strips. The feeding of the mounting strip 20 is stopped for a predetermined time, and the strip 20 is then severed transversely between two taps 27 so that the severed part with a tap thereon is seized by the travelling condenser strips 23, 24. A second mounting strip is similarly employed to feed a tap strap into contact with a second condenser electrode 25. This second tap is at a different distance from the end of the mounting strip 20 than the first strap, and the two paper mounting strips 20 are simultaneously severed, so that the taps are spaced in the condenser. The mounting strips 20 are fed from rolls 21 on spindles to pass between rollers 28 over feed plates 17, 18 and under knives 32, the end of the strips frictionally engaging the dielectric and metal strips converging to pass to the motor-driven winding shaft 2. One of each pair of rollers 28 is driven by a motor 29 on the same shaft 30 with a solenoid released brake 31. Energization of a solenoid 34 operates through a rod 125 and presses the knives 32 against return springs 33 to cut the strips 20. Fixed contacts 35 are in sliding contact with the mounting strip 20 and when' they contact a tap strap 27 thereon, a circuit is completed to stop the motor and operate the brake. The synchronization of the tap insertion with the winding circuit is controlled by contacts 40, 41 on a plate 39 on chains 36 on sprockets 37 on a shaft 38 driven by gears from the winding shaft 3. The contacts 40, 41 operate periodically switches 42, 43 which operate the tap winding motor 29 through ratchet relays 44, 45 energized from a transformer 46 through a holding relay 49, which may be manually energized. The mounting strips are first fed into place manually by knobs 73 on the ends of the shafts 30, the brakes 31 being released by energization of their solenoids by moving a manual switch 74 to the left. Press-button switches 69, 70 are depressed to move the first tap straps under the contacts 35. Cutters 11, 12 for the electrode foils 23 and a cutter 13 for the paper dielectric 24 are provided (see Group VIII).
