Title: Logic protection circuits for effecting an a.b. operation having a combined and/not function
IPC: B61L29/24
Filed: 1965-04-02
Abstract: A transistor circuit for producing the A.B function in a form represented by the presence or absence of oscillations uses an integrating circuit in the #A path, the output being zero (i.e. oscillations absent) if a fault develops in any of the components of the circuit. In Fig. 3 the A and B inputs are supplied as oscillations to the bases of transistors 10 and 26 respectively. The A signal is integrated by a long timeconstant RC circuit 40, 4 so that a steady voltage appears on the emitter of transistor 1 which is less negative than the supply 11. Transistor 26 is driven between cut-off and saturation by the B signal and its output is passed via an impedance reducing stage 19 to the base of transistor 1. Both extreme values of the B signal are more negative than the emitter potential of 1 due to the A signal so no signal is passed to the output transistor 33. If the A signal is absent, the emitter of 1 is at the potential of the supply 11 and transistor 1 acts as an amplifier for the B signal. The output transistor 33 is supplied through a capacitor 34 so that faulty D.C. levels in the input stages on transistor I cannot affect the output except by cutting it off altogether. The presence of an oscillatory signal on line 39 can therefore only represent #A.B and cannot be due to faulty operation of the circuit. In a modification (Fig. 5, not shown) the integrated A signal is passed directly to the base of the output transistor (41), to which the B signal is applied also via a capacitor (72) and common-emitter stage (63). If the A signal is present, the base of the output transistor (41) is driven positive and no output is obtained. In the absence of the A signal, the B signal drives the base (41) alternately positive and negative and an oscillatory output is obtained (at 77). As before, any fault in the circuit can only result in an absence of the oscillatory output.

Title: Optical sighting devices for light antiaircraft guns
IPC: F41G5/08
Filed: 1965-06-08
Abstract: A sighting device for an anti-aircraft gun, having a barrel pivotable about a horizontal axis mounted on a platform rotatable about a vertical axis with respect to a fixed base, comprises an eyepiece 4 and a window 5 both fixed with respect to the platform, an optical system coupled with the gun barrel so as to direct into the eyepiece the light beam parallel to the barrel which passes through the window 5, regardless of the inclination of the barrel, and a transparent plate 6 carrying a horizontal reference line 10 and displaceable by an amount directly proportional to the angular movement of the barrel so that the image of the target may be made to coincide with the reference mark. The plate 6 is coupled to one end of the lever 12 which is pivotable about a spindle 13. By adjustment of a handle 29 the spindle 13 is movable along a slot 26 in the lever 12 so as to vary the degree of movement of the plate 6 with rotation of the gun barrel. Rotation of the gun barrel then rotates a spindle 8 carrying a mirror 7 and through a gear train rotates a cam 11 against the edge of which the other end of the lever 12 is urged. Thus the cam 11 causes the lever 12 to turn about the spindle 13 and move the plate 6 until the image of the target coincides with the reference line 10. A fixed transparent plate having a plurality of lines which intersect on the axis of the eyepiece 4 is viewed together with the movable plate and permits the gunner to take into account estimated vertical and horizontal components of the target's flight.

Patent ES-322304-A1 (ES)
Title: Improvements in semiconductor devices
IPC: H01L29/73
Filed: 1966-01-27
Abstract: In a semi-conductor device which is not completely circularly symmetrical the effect of " current hogging " is reduced by contacting one region with a conductive layer the distance of the edge of which from the junction decreases as the distance from a low resistance contact applied to the layer increases. " Current hogging " is the concentration of the current flow at certain areas of a junction due to the geometry of the device. In a first embodiment a planar transistor having interdigitated base and emitter regions is produced and, as shown in Fig. 4, the emitterbase junction 13 is protected by an oxide layer the edge 12 of which defines the effective edge of a conductive layer 15 forming the emitter contact. Layer 15 is provided with a low resistance contact 18 and the effective edge 12 of the emitter contact 15 is closest to the junction 13 at those regions furthest from contact 18. Since the base contact carries much less current than the emitter contact the effective edge 11 of the base contact 14 can be spaced a constant distance from the junction 13. In a modification, Fig. 5 (not shown), the effective edges of the base and emitter contacts are spaced a constant distance apart, but the location of the PN junction between them varies to reduce the effect of " current hogging " in the base and emitter regions. In a further embodiment, Fig. 6 (not shown), the base and emitter regions are circularly symmetrical, the emitter electrode is in the form of a circular contact layer and a low resistance contact to the layer both symmetrically arranged, but the base contact is applied to a base contact layer at a peripherally located point, and to reduce the effects of " current hogging " the distance of the effective edge of the base contact layer from the junction is varied by forming the outer edge of the oxide covering the junction in a circle the centre of which is displaced from the centre of the emitter region towards the base contact. The method of producing a planar epitaxial NPN transistor is described in detail. The contact layers comprise aluminium evaporated over the masked surface and masked and etched to produce the required electrodes. The device is gold-soldered to a molybdenum disc which is soldered to a copper header. The contact layers are connected to lead-out wires by means of aluminium wires. It is also described how the method can be modified to produce mesa transistors. Reference has been directed by the Comptroller to Specification 1,032,599.

IPC: B29C48/11
Filed: 1966-02-19
Abstract: A double-walled ceramic pipe, Fig. 8 (not shown), wherein the walls are connected by a plurality of bridges which run the length of the pipe, is made by extruding the ceramic material through an annular array of orifices in a die plate 21 to enter inserts 27, from which the material moves laterally through apertures 28 and is then constrained to move axially between annular walls 23, 24 of die plate 21 and plates 26, fixed to the downstream ends of inserts 27, and between plates 26 themselves. The form of the bridging between the pipe walls is dependent on the number and shape of plates 26 which may be, for example, triangular, Fig. 3 (not shown), or circular, Fig. 6 (not shown).

Patent ES-341831-A1 (ES)
Title: Joining overlapped metal sheet edges
IPC: B23K11/06
Filed: 1967-06-15
Abstract: In joining overlapped sheet metal edges of which the facing surfaces are coated with low melting-point metal the overlapped edges are resistance welded by wire-like electrodes having a small contact area with the outer surfaces of the overlapped edges and advancing with the edges and after being welded the edges are squeezed together so that the melted lower melting-point metal is distributed to reduce the risk of corrosion after it has solidified. Tinned or galvanized sheet iron shaped to form a can body is introduced with its edges 44, 46, Fig. 4, between the electrode rollers 5, 7, Fig. 1, of a welding machine having a wire 9 forming a moving electrode surface passing over each of the rollers 5, 7. The electrode 7 is carried on a lower fixed arm 1 and the electrode 5 is on a pivoted upper arm 3 and lower roller 19 is carried on bracket 21 on the arm 1 to cooperate with a roller 15 on a pivoted arm 13. The roller 15 is driven from the electrode roller drive but both rollers may be driven. The can body passes between the rollers 5, 7, whereby the weld 48 is produced and the welding heat causes melting of the tin coating which flows between the overlapped part 44, 46 pressed together by the rollers 15, 19. The can body then passes a nozzle 23 which sprays a protective film 52. In a modified machine the rollers for exerting pressure subsequent to the electrode rollers are both idlers. A separate heating source may be provided between the electrode rollers and the pressure applying rollers and both sides of the overlapped edges may be sprayed with the protective film.
