Abstract: 1,252,162. Continuous casting. MONSANTO CO. 5 Nov., 1968 [6 Nov., 1967], No. 52362/68. Heading B3F. [Also in Division C1] In a process for forming fibres, filaments or films by extruding a stream of molten material through an orifice 18, the physical parameters of the process are so controlled that in a first zone A the velocity of the stream is greater than the upstream velocity of disturbances caused by aerodynamic drag, and in a second zone B the velocity of the stream is less than the upstream velocity of disturbances caused by aerodynamic drag. Thus the upstream extent of such disturbances is maintained intermediate zones A and B. The physical parameters which may be varied to achieve said control include the direction and rate of flow of the atmosphere surrounding the stream, the nature of the gas constituting said atmosphere, and the extrusion velocity of the stream. On passing from zone A to zone B the aerodynamic drag is increased and/or the velocity of the stream is decreased. The latter may be achieved by use of a deflection plate 44 located between the two zones and the former by using a gas of greater density and/or viscosity in zone B as compared to that in zone A. Alternatively the gas within zone B may be maintained at a lower co-current or higher counter-current velocity than that in zone A. The gas used in zone A is one which will stabilize the stream against break-up before solidification by forming a thin film on it as described in Specification 1,153,577. The melt 16 is forced through an orifice 18 in a ruby jewel or molybdenum insert 20 by an inert gas such as argon supplied via a valve 26, and its temperature measured by a thermocouple 24. On entering zone B the stream becomes aerodynamically contorted to a substantially helical configuration and may be withdrawn without disruption. An example describes the preparation of a filament from a mixture of 62% Pb and 38% Sn using -an atmosphere consisting of 7% oxygen and 93% helium in zone A and of air in zone B. In zone A the gas flow was in the same direction as that of the stream, i.e. co-current, and in zone B was in the opposite direction, i.e. counter-current.

Abstract: 1,252,183. Utilizing radiation detectors. A. PIERBURG AUTO-UND LUFTFAHRTGERATEBAU K.G. Jan.29, 1969 [Aug. 19, 1968], No. 4940/69. Heading G1A. [Also in Division E1] Apparatus to measure fluid-flow in a duct 11 includes a gear pump 12 driven by an electric motor M so as to maintain the pressure difference across the gears substantially zero. A tachometer N indicates the flow-rate. Pressure variations in bores 13, 14 affect the positions of an element 26 on a spring 27 and a free piston 22 having a density equal to that of the fluid. The element and piston lie in a passage 15 between said bores and are rendered opaque so as to vary the light reaching photo-sensitive resistors, or semi-conductors, 23, 30 from a source 19 through transparent tubes 17, 18 and slots in opaque plates 20, 21. The algebraic sum of positive signals a, b and a negative signal c derived from the resistors, or semi-conductors, and the tachometer is fed to the motor through an amplifier V. An increase of pressure at the bore 14 rapidly depresses the element 26 and thus causes the motor to accelerate. The piston responds at a slower rate and reduces the signal b so as to stabilize the motor speed. Increases of friction at the gears diminish the signal c and thereby augment the input to the motor. Stops 24, 28, 29 prevent excessive movement of the piston and element. The electrical system may be as shown in Fig. 3 and include an n-p-n transistor T to compensate for supply voltage variations, fluctuations in the output of the source 19, errors in the location of the element 26 and temperature changes at the amplifier. To simplify the apparatus the element 26 may be dispensed with and the piston placed in the tube 18. The apparatus can be adapted for use as a flow regulator by driving the gears with an auxiliary motor and connecting the motor M to either a variable throttling-device or a second pump in the duct 11 on one side of the pump 12 or the other.

[Also in Division  F1] Liquid pumped through rigid tubes 3, 4 and a resilient connecting tube 1 is caused to pulsate by locally restricting the resilient tube thus causing periodic cavitation downstream of the restriction and oscillation of the resilient tube. As shown the local restriction is effected by an adjustable spring-loaded clamp through which the oscillations are transmitted to a closed liquid-filled casing 10 embedded in material e.g. soil or concrete which it is desired to tamp. The oscillation set up in tube 1 may be transmitted directly to two or more partially mixed liquids admitted to the casing 10 through an apertured tube 15; the resulting fully mixed liquids then being withdrawn through a tube 16. In a modification the local restriction is effected by bending the resilient tube back against itself.

A shallow surface layer of a semi-conductor device is contacted by means of a deeper region of the same conductivity type which penetrates the shallow layer at its centre, an electrode being applied to the deeper region. An N type Si wafer (1) is masked with a silicon oxide or nitride layer (2), a window (3) is formed and boron is diffused-in to form a deep P type contact region 4. The window is enlarged and a second boron diffusion is used to form the shallow P type active region 6.

A layer 10 of Ni covered with a layer 11 of Ag is vapour deposited to contact the P type region and parts of the metal layers overlying the insulating layer are removed together with the photoresist used in the etching of the window (9). A mound 12 of Ag is vapourdeposited or electrodeposited to contact layer 11 and overlie the insulating layer 8 to provide a large area bonding pad, Fig. 6. The impurity concentration of the deep region 4 is arranged to be less than that of region 6 so that the latter constitutes the active region of the device.

Abstract: 1289136 Moulding fibre-resin articles SUMITOMO ELECTRIC INDUSTRIES Ltd 28 Nov 1969 58392/69 Heading B5A Elongated fibre-resin articles are made by drawing a fibrous reinforcement having a predetermined number of relatively slack fibres through a resin impregnation chamber and then through a heated die. The slack fibres, since they contain regions oriented in the transverse direction, lend to the finished article considerable strength in the transverse as well as the longitudi - nal direction. In the particular embodiment, the reinforcement is drawn through a resilient inlet 5 into an impregnation chamber 4 through which resin is fed via injection port 8 and discharge port 10 and from which air is exhausted through port 9. The exhaustion of air facilitates complete penetration of the resin into the reinforcement and eliminates bubbles in the finished article. The impregnated reinforcement then passes through the heated tapered outlet 7 into a heated die 13 where solidification of the resin occurs. The resin may be a polyester, an epoxy, a phenolic or a diaryl phthalate prepolymer and the fibres of the reinforcement may be glass, a carbonized material, a polyamide, a polyester, a polyvinylalcohol or jute.
