Abstract: 1,012,984. Capacitors. E. MITTELSTENSCHEID, C. MITTELSTEN-SCHEID, and A. SILLER, [trading as VOWERK & CO.]. April 16, 1963. [April 21, 1962], No. 14759/63. Heading H1M. A variable capacitor for short, medium, long and ultra-short waves and comprising a casing around the rotor and stator vanes, is characterized in,that the ultra-short wave rotor vanes are generally semi-circular and, near the maximum capacity position, project from the stator vanes into the gap between the stator vanes and the casing, the area thus lost being compensated for in all positions by an additional area provided at the opposite edge of the rotor vanes, to ensure a linear frequency change on ultra-short waves. Referring to Fig. 4 if the ultra-short wave rotor vanes 4 are rotated clockwise past the position shown, the edge 7 will project from the stator vanes 2 towards the casing 1. An additional area F 2  on the opposite edge of the rotor vanes is provided as compensation. The rotor vanes for the other wavebands (not shown in Fig. 4) are of reniform shape.

[Also in Divisions H1 and H3] A PN junction is formed in a crystalline P- type silicon carbide body by fusing a quantity of silicon to the body in the presence of nitrogen from a source such as a nitrogen-hydrogen gas mixture. As an example, a diode is produced by taking a silicon carbide body degenerately doped with aluminium, placing silicon fragments in contact with a region of the body, briefly heating the assembly to about 2000‹ C. in a 90% v./v. nitrogen-hydrogen mixture, and then rapidly cooling to room temperature. It is stated that up to 1% of impurities such as gallium, arsenic or phosphorus in the silicon have no discernible effect on the conductivity type of the recrystallization region. Wires are ohmically connected to the body and to the N-type region produced. Light is emitted when a current in excess of the tunnelling current is passed in the forward direction.

Abstract: 1,225,680. Stacking articles. MOORE-IEM Inc. 31 Oct., 1968, No. 51576/68. Headings B8A, B8B and B8C. A machine for stacking boards 62 comprises a framework 10, board supporting means 28 movable forward, down, back and upwards relatively to the frame, power means 40, 42, 44 being provided for effecting the forward and backward movement and control means for the power means, a gravity operated device 30, 33, 35 being provided to control and provide the up and down movement of the board support means 28. The framework comprises vertical members 11, upper members 12 on to which the boards 62 are introduced by a conveyer 61, and lower members 19 on which the boards are, in one embodiment, stacked. Within the framework is a carriage 20 movable to the right, as seen in Fig. 1, by the rotation of the motor driven wheel 42, a crank arm 38 moving therewith being attached by a link 40 to the carriage. The carriage presents arms 28 movable vertically on the carriage and provided with a counterweight 30 attached to the arms by chains 33 and normally biasing the arms upwards. When the carriage is in its fully leftward position within the frame, rollers on the arms engage under inclined plates on the frame which hold the arms below the upper surfaces 19 of members 12. Boards fed to the upper members are moved therealong by a chain conveyer 14, 15 on the frame until the leading board reaches stops 57, a switch 58 then being actuated to allow the motor 45 to drive forward carriage 20. This movement is controlled by cams and switches on wheel 42. As the carriage moves the arms forward rollers thereon rise up cam faces on the framework to lift the layer of boards and carry them forward to the upper position shown in dotted lines. At this position rollers on the arms are freed from tracks on the framework and the combined weight of the load and the arms overcome the counterweight 30, the arms descending with the load to the lower position where switch 56 is operated by a lever 49 sensing the position of the top of the timber stack to cause the carriage to move back to its original position, the boards being stripped from the arms by the uprights 11. The counterweight then raises the freed arms to their upper position. The cycle is repeated, providing a stack of such layers of boards. End guides for the boards may be provided on the arms. The arms may deflect under the load of boards to reduce the distance through which the boards fall as they are stripped therefrom. The framework may itself be mounted on a carriage movable transversely between spaced locations at which stacks are required, the surfaces on which the boards are stacked then being independent of the framework.

Abstract: 1,238,437. Fluid-pressure servomotor systems. KNORR-BREMSE G.m.b.H. April 24, 1970 [April 26, 1969; Feb.13, 1970], No.19938/70. Heading G3P. An apparatus for controlling the filling of a container 1 with liquid comprises a piston 4 which raises an empty container to a filling station (not shown), the container thereby closing a switch 12. Fluid from a main duct 17 passes to the fluidic devices 5, 6, 7, 8, 9, 10 via a throttle 19, that of the device 10 causing a pulse at the control input 21 when the switch 12 is closed. The device 8 switches from stable to astable condition and the collapse of pressure in line 24 causes the device 7 to assume its stable state until such a time that the pulse from the delay line 26 arrives at the control input 27. The pulse in the line 28 causes an output at 31 of the bi-stable device 5 which passes through a detector tube 2 into the open air. Also, the absence of an output at 32 of the device 5 puts the device 6 in its stable state in which an output in line 36 is fed to an amplifier 18. Fluid from the main duct 17 then passes to the cylinder 3 to lower the container whilst the latter is being filled at a rate corresponding to the lowering of the piston 4. At the end of the travel of the piston the filling liquid blocks the tube 2. A pulse is thus fed back via a line 43 to a control input of the device 5 switching the latter to its other stable state. An output at 32 switches the device 6 to its unstable state and supply of fluid to the cylinder 3 is cut off. A similar arrangement is disclosed in Fig. 2 (not shown). If a disturbance occurs during the filling operation or during the changing of containers 1, the switch lever 14 is depressed by; means not shown which causes a pulse to be applied to the control input 42<SP>1</SP> of the device 5 so stopping fluid passing to the cylinder 3.

Abstract: 1,250,490. Coiling helices; making tubes. CARIBBEAN HOLDINGS Ltd. 2 Oct., 1968,  No. 46660/68. Headings B3A and B3E. [Also in Divisions C1 and F2] A method of forming cylinders from strip material comprises feeding a strip 36 on to the rear edge 32 of a skirt 33 which is rotated, together with a frusto-conical head 24, by a belt drive 45 which engages the forming cylinder in two spaced diametrically opposite portions to impart a rotational force. In a first embodiment, Fig. 3, the belt drive has an inclined rotational axis with respect to the skirt 33 to impart a longitudinal force as well as the rotational force. Initially the skirt and forming head are rotated and moved a distance D to provide the required area of bonding between the skirt 33 and the wrapped cylinder after which the forming head 24 is stopped from moving axially by a collar 23. The wrapping then proceeds on the forming head 26 from which the wrapping slips off axially as the head is restrained from further axial movement. The turns are joined together by a heater either by melting a brazing alloy or by tack welding the two sides. In a second embodiment a cylindrical head is provided with a plurality of slots spaced in the peripheral portion of the head adjacent the end upon which the coils are wound. In a third embodiment a non-twisted belt drive provides the rotational movement while the axial movement is provided by driving wheels on a track so as to move the skirt 33. In a fourth embodiment a forming head 70, Fig. 7, is rotated by a drive belt 45 and is provided with conveyer belts 73 in the head 70 for imparting a longitudinal force. In a fifth embodiment, Fig. 9, a closed container is formed by winding the strip on an end closure 102, which is moved axially a distance x manually. When the strip moves off part 104 it immediately winds on end closure 124 and winding will continue until a stop collar 144 hits a fixed bearing 140. At this point end closure 124 will stop and act as a forming head, allowing the cylinder to grow to a desired length after which the end closure 124 will advance a distance y which will complete the winding. In a switch embodiment the skirt is moved axially in a horizontal direction by supplying compressed air through the shaft fixed to the forming head. A final embodiment is given in which the skirt is moved axially in a vertical direction.

Abstract: 1,251,713. Inspecting systems; using coherent radiation. PERKIN-ELMER CORP. 2 Jan., 1969 [2 Jan., 1968], No. 340/69. Heading H4D. [Also in Division G2] Variations of an object under test from a known standard are determined by establishing a pattern corresponding to a wave-front of coherent radiation as altered by the standard, exposing the test object to coherent radiation and comparing a wave-front of the radiation as altered by the test object with the pattern. The object may be one which reflects, refracts, or diffracts the radiation. The radiation may be acoustic or electromagnetic (selected so that the wavelength is comparable with any dimensional variations, e.g. defects in an object, to be determined) and may propagate in a liquid or gas or (if electromagnetic radiation) vacuum. In the Fig. 1 arrangement the pattern (an acoustic hologram) is established by energizing pointsource transducers 10 and 14 to produce respectively an " object beam " 12 reflected from standard object 13 and a " reference beam " 15. The interference pattern of the two beams is detected by a scanning transducer 17 whose amplified output modulates the brightness of a coupled lamp 18 to give a photographic reference pattern 20. Transducer 14 may be omitted if a delayed version of the transducer 10 electrical driving signal is added to the output of transducer 17. If now an " object beam " from a test object 27 (Fig. 3) is incident on a representation 25 of the reference pattern, the representation will focus it to a point unless the test object differs, e.g. by having a defect 28, from the standard object, in which case the output of receiving transducer 23 will be of lower amplitude than if the two objects matched. Representation 25 may be a metal plate apertured at points corresponding to the maxima of the interference pattern 20 recorded, or it may be an optical filter or a suitably configured lens or mirror. For objects having relatively simple surfaces the lens transmission characteristics or reflector shape may be computed by feeding object shape, radiation and system positional data into a computer. Transducer 23 output operates a meter 24 or a reject mechanism. Collimated beams may be used instead of point-source beams.
