Title: Die for use with a punch for stamping out blanks from sheet material
Inventor: EVANS FREDERICK STANLEY
IPC: B21D37/20
Filed: 1961-08-30
Abstract: 914,518. Cutting dies. JAGUAR CARS Ltd. Aug. 30, 1961, No. 31169/61. Class 31 (1). [Also in Group XXII] In a die for sheet material, the cutting edges are formed by one edge of steel strips, the opposite edges of which abut a back-plate, the strips are inter-connected with members of a frame which, is also secured to the back-plate and surrounds and is spaced from the strips, and the channel formed between the frame, the strips and the back-plate is filled with a hard-setting resin to the level of the cutting-edges of the strips. The die comprises a back-plate 10, a frame of angle iron members 11, 12, 13 and 14 welded together as at 15, 17 and held to the back-plate by screws 16. Steel strips 18 to 27 which form the cutting edges are arranged in the desired form and are supported from the frame by struts 28 to 35 which are brazed or otherwise secured in position. The strips are welded together on the outside. The channel between the strips and the frame is filled with a hard-setting resin and preferably the die cavity is filled with resin to a level which will not impede the stroke of the punch. There are holes through the strips to bond the two fillings. The back-plate 10 and the outer filling can be provided with aligned holes for guiding an ejector. The coacting punch comprises a suitably profiled punch member and is secured by screws and dowels to a block of hard-setting resin which is similarly secured to a back-plate.

Patent GB-1390139-A (GB)
IPC: G01R31/04
Filed: 1973-07-02
Abstract: 1390139 Testing interconnections TERADYNE Inc 2 July 1973 [13 July 1972] 31387/73 Heading G1U To test interconnections between a number of terminal points in a matrix, each is provided with a test unit which can be selectively operated to connect its respective point to either of two buses or to isolate it from both. The matrix may contain thousands of points, and a circuit is described suitable for manufacture as a 16-pin integrated circuit dealing with eight terminal points. This has eight test units 10-17 including a latching device 39 and F.E.T.'s 25, 27-29 and further includes a decoding network 50 which receives inputs A1-A3 and CE from a computer (not shown) to selectively activate one of the test units. Common signals V DD  (positive supply), V SS  (ground), G (gate signal) and R (reset) are supplied to all the units 10-17. The reset pulse R sets Q to low and Q to high, thus isolating the output 30 from the positive supply through transistor 25, the output 30 also being isolated from ground by transistor 29. The computer then successively selects the code A1- A3 corresponding to all the terminal points connected together in a particular network. Detection of the appropriate code produces a signal So at the corresponding unit. This sets Q to high and connects output 30 to ground via transistor 27. When the address code is removed, transistor 25 is rendered conductive, (Q-high, S o -low) and the terminal point is connected to the positive rail via F.E.T. 25. As each point is tested, if the connections in the network are correct, the current drain should increase as the point is addressed and then decrease after addressing. When each point in the network has been tested, a slowly rising gate signal G is applied to all the units. This has no effect on the units already addressed, but the others (which should be isolated from this network) are connected to ground through a slowly reducing resistance provided by transistor 29. Any increase in current drain indicates a faulty interconnection. Complementary symmetry F.E.T. devices are used throughout the integrated circuitry so that the current drain of the devices is small and constant whatever their logic state.

Title: Improvements in or relating to disazo disperse dyestuffs
IPC: C09B31/043
Filed: 1963-08-09
Abstract: The invention comprises disperse disazo dyes of formula <FORM:1008853/C4-C5/1> wherein R1 and R2 each represent a hydrogen or chlorine atom, C1 or C2 alkyl, C1 or C2 alkoxy or nitro radical, R3 and R4 each represent a hydrogen or chlorine atom or a C1-C2 alkyl or alkoxy radical, A is a benzene nucleus and B is a benzene or naphthalene nucleus.

Title: Improvements in the operation of gas-filled electric discharge tubes containing luminescent materials
IPC: C09K11/77
Filed: 1936-11-18
Abstract: 490,663. Discharge lamps. SERVIGNE, M. Nov. 18, 1936, No. 31558. [Class 39 (i)] [Also in Group XX] The luminescent material in a gas- or vapourfilled discharge tube comprises a solid solution of a rare earth in a fluorescent salt of tungstic or molybdic acid, e.g. calcium tungstate or molybdate, admixed if desired with other fluorescent materials, e.g. zinc silicate. Rare earth metals mentioned are samarium, erbium, dysprosium, and gadolinium, and a composition is described for use for example in a mercuryvapour tube and containing calcium molybdate activated with samarium (0À1-2 per cent), and also calcium borate or tricalcium orthophosphate as stabilizer as described in Specification 485,373, [Group III]. As fluxes, alkaline salts, e.g. sodium chloride or borax may be added. The proportion of tungstate to samarium may be adjusted to give a white response if a green-fluorescing substance such as zinc silicate is also added. The red emission from the samarium may be enhanced if the mixture, instead of being merely calcined in the usual manner, is completely fused. As the emission of the tungstate diminishes with rise of temperature of the tube during operation, while that of the rare earth metal remains constant causing the luminescence of the mixture to become redder, the colour emitted from the tube may be varied by varying the current fed to the tube. The tube may be operated not only under the usual pressures of about 1 mm. of mercury, but at lower pressures below 0À1 mm., e.g. at 0À01 mm. in an atmosphere of xenon.

A PN junction is produced by gaseous deposition of impurities of one conductivity type on to a semi-conductor wafer of the opposite type to form a surface layer and a thin diffused layer, then etching off the surface layer and again predepositing the impurity. This repetition of the process reduces the number of non-uniform regions which arise in normal diffusion processes due to the presence of undesired particles on the surface. In one example a layer of phosphorus is deposited on a P-type silicon wafer by heating the wafer to 700-800 C. for 10-30 minutes in an atmosphere of P 2 O 5 , etched off by treatment in hydrofluoric acid and then the process is repeated several more times. Alternatively, an N-type wafer could be treated with vapour of B 2 O 5  in a similar manner.

Abstract: 618,626. Snap-action switches. ALLDAY & SON (1922), Ltd., H. and BAIN, R. Nov. 6, 1946, No. 32939. [Class 38 (v)] In a switch for alternating currents, one of a pair of L-shaped movable contacts f, of the same length, projects from a carrier e to a greater extent than the other, whereby, when the carrier e is slid to close the switch, the said contact engages its fixed contact c and is momentarily held thereby, so that the overlapping ends of the contacts f engage one another before the other contact f engages its contact c. Springs h effect rapid closure when the slide is moved past its central position by a guided finger-piece m having a lost-motion connection k, r with the slide. When the switch is opened, both contacts f are gripped by contacts c, and the contact which projects further moves relatively to the other to form the microgap g whilst the slide is still under the control of member m, thereby producing a slow break. A springs, compressed between the base a and the inner ends of contacts f, maintains the latter in engagement when the switch is closed. The slide may be buffered by a spring u, and the finger-piece m by springs 2 engaging stops 3 on the base. The contacts f may project to the same extent in which case the fixed contacts are of different lengths.
