Title: Solid state electronic devices
IPC: H01L23/29
Filed: 1973-04-09
Abstract: 1428179 Semi-conductor devices WESTING- HOUSE ELECTRIC CORP 9 April 1973 [19 April 1972] 16826/73 Heading H1K [Also in Divisions C6-C7] The leads 41 of a solid-state device are electrolytically coated by making them anodic in a solution or colloidal suspension of an amine or imidazole salt of a polyamic acid (polyamide acid) and the material thus electrodeposited is heat cured to a polyimide film which forms flexible void-free interfaces with the leads and with a subsequently applied encapsulant which covers both the device and leads. The relative quantities of amine, polyamic acid, and solvents are critical, for both solution and colloidal suspension. In each case, more than one non- aqueous organic liquid is present in the composition. One or more of these act as a solvent for the polyamic acid and one or more act as non-solvent for the amine or imidazole salt of the acid. A variety of amines and imidazoles are listed. Solvents for the acid are N : N- dialkyl carboxylamides, dimethyl-sulphoxide, and pyridine. The non-solvents listed for the salt are all ketones. As shown a P+N silicon diode 40 has its body and electrodes protected with a silicon grease coating 45 while the leads are coated with polyamic acid and the device heat treated to form the polyimide. The diode is then vacuum baked, encapsulated with a mineral filled epoxy resin, and further baked to cross-link the resin. In general, encapsulants may be epoxy, silicone, polyester, phenolic, or diallylphthalate resins and may be filled with silica, benyl, or talc. Transistors, gate-controlled switches, and integrated circuits may be similarly treated.

Title: Electrolytic shaping of metallic aerofoil blades
Inventor: GOODWIN FREDERICK LEWIS
IPC: F01D5/14
Filed: 1962-05-07
Abstract: 937,737. Electrolytic shaping of aerofoil blades. ROLLS-ROYCE Ltd. May 7, 1962, No. 17560/62. Class 41. Metal is electrolytically removed from at least one longitudinal edge of an aerofoil blade, while the blade is held stationary, so as to radius that edge, e.g to give it a radius of up to 0.15 inch. Fig. 1 shows an aerofoil blade 25 with shaping electrodes 11, 12 spaced from the blade edges by gaps 35, 36. Jets of electrolyte are supplied to these gaps through pipes 44, 41, 42 and elongated outlets 47, 48. The blade is made electrically positive relative to the electrodes 11, 12. The electrodes, instead of having knife edges, as shown in Fig. 1, may have concave surfaces 58, Fig. 4. The blade may be formed initially as a forged blade blank and prior to the electrolytic shaping, may be milled or ground to remove " flashing " and, to form a flat surface as shown in Fig. 4. Stated electrolysing conditions are a gap of 0.003-0.005 inch, an electrolyte comprising 12% by weight Na 2 SO 4  and 5% borax, an electrolyte flow rate of 3 to 7 gals./min., a voltage of 6-15 and a current density of the order of 200 amps./sq. inch. Since different amounts of metal are removed from the two edges of a blade, different electrolysing conditions may be used at each edge in order to ensure that the shaping of both is completed in the same time. Shaping of a blade where the cross-section varies along its length and shaping of a blade which is twisted about its longitudinal axis are also referred to.

Title: Printing arrangement with moving printing head

Filed: 1975-04-28
Abstract: 1497903 Printers ING C OLIVETTI & C SpA 28 April 1975 [10 May 1974] 17591/75 Heading G4H A printing arrangement for printing lines of characters comprises a printing head, a reversible D.C. electric motor coupled to the head for driving the head forwards and backwards along a printing line, depending on the direction of movement of the motor, and control means including a supply circuit arranged to feed a first voltage to the motor during a stage of printing a line of characters, to move the head forward, and arranged to feed to the motor a second voltage which is of opposite polarity to and greater magnitude than the first voltage, in order to move the head backwards following printing of a line of characters. As disclosed, the second voltage is replaced by a third voltage of the same polarity but smaller, towards the end of the return movement. The print head, which has a column of thermal print elements, is moved to the right at a relatively low speed for printing, until a counter driven by headcarriage-movement clock pulses equals the number of characters in the line required, when the head is driven leftwards at a relatively high speed until a photodetector is reached after which leftward drive continues at the relatively low speed until a second photodetector is reached at which the head stops. Speed stabilization feedback is provided for the head motor. If the leftward drive starts to the left of the first photodetector (i.e. short line), only the lower speed is used. If initially, before the rightwards movement commences, the head is not at the second photodetector, low speed leftwards drive brings it to this position.
