Title: Data card and method of manufacture of a data card
IPC: G06K19/00
Filed: 1965-12-13
Abstract: 1,080,510. Making record cards. HAMILTON TOOL CO. Dec. 13, 1965 [Jan. 14, 1965], No. 52889/65. Heading B4B. [Also in Division G4] A method of manufacturing notched data cards comprises forming slits 32 along transverse lines 30 and excising the ties 34 between the slits by punching holes 36 through the web. The slitting and punching may be performed by conventional roll apparatus while the web is in continuous motion. The punchings may be removed by air movement.

Patent GB-1594270-A (GB)
Title: Casting method employing a vacuumshaped mould
IPC: B22C9/08
Filed: 1977-12-21
Abstract: In the casting method by means of a mould produced with the application of a vacuum, a blind riser (10) with a vent opening (12) is formed and a conical body (13) is arranged in the upper region of the blind riser (10), which body is intended to extend to below the level reached by the molten metal in the blind riser (10) after it has been poured in. Due to the contact between the molten metal and the conical body (13), heat is stored in the heat-resistant material (4) of the mould in the area around the blind riser (10), delaying the solidification of the molten metal in the blind riser (10). This favours the flow of additional molten metal from the blind riser into the casting inside the mould and, as a result, shrinkage losses are compensated. <IMAGE>

Title: Improvements in Methods of and Moulds for Injection-Moulding Soles on to Footwear Uppers
IPC: B29D35/08
Filed: 1968-11-11
Abstract: 1,173,260. Injection moulding soles on to uppers. DESMA-WERKE G.m.b.H. 11 Nov., 1968 [22 Nov., 1967], No. 53258/68. Addition to 1,143,530. Heading B5A. [Also in Division A3] The method of the parent Specification is applied to the production of multi-part e.g. multi-layer soles, the material for each part being injected into a mould cavity 16 (Fig. 1) which is larger than the sole part, the cavity 16 being then reduced so as to form the sole part and bond it with the shoe upper or with a previously moulded shoe part. As shown in Fig. 1 material for the layers 17, 18 is injected through passages l2a, 12b respectively, the bottom plunger 11 being in the position shown during both injections. In an alternative arrangement (Fig. 2, not shown) the bottom plunger assumes an intermediate position for the first injection with the lower injection passage cut off by the plunger. In the example shown in Fig. 3, the bottom plunger 11 has an upstanding flange 20 which helps to prevent intermixing of the material of the two layers 17, 18. A marginal strip 21 is provided at the first injection stage..

Title: Voltage variable capacitance device and a method of producing such a device
IPC: H01L29/93
Filed: 1970-11-10
Abstract: 1323443 Semi-conductor devices INSTITUTET FOR HALVLEDARFORSKNING AB 10 Nov 1970 [17 Nov 1969] 53488/70 Heading H1K A varactor includes a layer 3, 4 of insulating material capable of permanently storing electric charges in a distribution which is non-uniform across the surface of the device, the layer 3, 4 being provided on the surface of a semiconductor body 1, 2 of a single conductivity type in the surface of which a barrier layer may be formed by the application of a suitable voltage to an electrode 5 on the insulating layer 3, 4. The device thus effectively comprises a voltagevariable barrier layer capacitance in series with a fixed value capacitance across the insulating layer 3, 4, and by controlling the quantity of charge permanently stored in the layer 3, 4 the values of voltage for which the overall capacitance is variable may be adjusted. It is possible in this way to produce a device having a linear capacitance-voltage characteristic over a desired range of voltage. The permanent charges are preferably stored at the interface of two insulating layers 3, 4 and in the upper layer 4, being trapped there as a result of tunnelling which is caused to take place through the relatively thin lower layer 3 by the application of a high voltage of appropriate magnitude and polarity across the device. The lower layer 3 may be of thermally formed silica and the upper layer 4 may be of silicon nitride, non-thermally formed silica or alumina. The semi-conductor body 1, 2 may be of Si or Ge. The non-uniform stored charge distribution may be achieved by applying different high voltages across different areas of the insulating layer 3, 4, and in a preferred arrangement this is carried out by providing a resistive layer (5a), Fig. 3 (not shown), of varying width on the insulating layer and applying a potential difference between terminal contacts (6, 7) at opposite ends of the layer (5a). In an alternative arrangement the charges are initially stored uniformly across the whole area of the device and part of the thickness of sections of the insulating layer is then removed, taking with it some of the stored charges and rendering the charge distribution non-uniform.
