Abstract: 1,021,068. Valves. X-LON PRODUCTS Ltd. Nov. 25, 1964 [Nov. 28, 1963], No. 47087/63. Heading F2V. A stopcock comprises a barrel-shaped housing 1 within which is mounted a hollow cylindrical (or conical) plug 12 positioned by a groove 19 and projection 3 and/or by axial projections (not shown) which engage the base of the barrel, the plug being made of a plastics material, e.g. polythene, and the walls of the plug being flexible so as to be forced into sealing engagement with the barrel by pressure fluid within the plug. Annular raised edges may be provided within the housing around the inlet and outlet 5, 6 to releasably engage the holes 14, 15  in the plug when the latter is in the open position. A cylindrical guide may project from the base of the housing into the plug to prevent the latter collapsing under negative pressures. There may be more than one outlet.

Abstract: 1,073,409. Supporting pipes. F. MULLER, and H. MLLER. Nov. 9, 1965 [Nov. 18, 1964], No. 47456/65. Heading F2P. An adjustable pipe-support comprises a suspension band 3 fastened at its top end to a carrier 7 attachable at 9 to a fixture and with its bottom end 14 passed through two slots 6 in the radially flanged ends of a clip 1 which embraces the pipe and is bent upwards so as to be clamped against the outer lateral surfaces of the flanges by a ring 5 which is moved down the band 3 until its bottom edge rests on the annular portion of the clip 1. The end 14 may then be lopped off to leave a short length protruding above the upper edge of the clip, which is then turned down over the said clip-edge for extra security (Fig. 1, not shown). The ring 5 may have a lengthwise slot as shown in Fig. 2; or it may be a closed ring of rectangular section or with one long face concave, the better to clamp the band 3 against the flanges of the clip. It is slightly less wide than the clip ends are long, so that they protrude above it when in position.

Title: Detection of ferromagnetic materials
IPC: G01V3/10
Filed: 1972-10-17
Abstract: 1418476 Detecting metal electrically J FRANKEL (ALUMINIUM) Ltd 28 Sept 1973 [17 Oct 1972] 47695/72 Heading G1N The presence of a ferromagnetic material e.g. iron, in a bale of non-ferromagnetic metallic material e.g. aluminium or copper, is detected by subjecting the bale to the magnetic field generated by an A.C. energized winding and monitoring the potential difference across the winding. Primary P and secondary windings S are wound on a rectangular former through which bales of material to be tested are conveyed, Fig. 1 (not shown). Initially a standard bale of aluminium is positioned in the former and potentiometer 20 adjusted until the change in the potential difference across the secondary is the same as the change in potential difference across the primary. Potentiometer 19 is then adjusted so that the circuit including the four full wave rectifiers 13, 14, 17, 18 is balanced as indicated on meter 22. The bales to be tested are then conveyed through the windings. Any ferromagnetic material present results in the potential differences across windings P, S increasing by equal amounts and the balanced condition is upset which is indicated by meter 22 or an alarm activated. To compensate for fluctuations in the A.C. supply connected to constant voltage source 12 and potentiometer 19, potentiometer 21 is adjusted to provide a small output across rectifier 18 which is out of phase with but of the same order of magnitude of the fluctuations in the rectifier outputs. The voltage source 12 has a frequency in the range 5 to 15 Hz when aluminium is being tested and 8 to 25 Hz for copper. Only one winding may be used and the potential difference across this winding monitored, the frequency of the A.C. source being such that changes in the potential difference across the winding are resulting from the presence of non- ferromagnetic material are rendered negligible.

Abstract: 1368314 Semi-conductor devices SIEMENS AG 14 Oct 1971 [20 Oct 1970] 47812/71 Heading H1K [Also in Division H3] In each of the two branches of a bi-stable trigger stage forming a memory element an MIS capacitor is provided in parallel with a PN junction or Schottky diode by extending a metal electrode 34 of the diode over the adjacent insulating material 35 to form the metal electrode of the MIS capacitor. In the embodiment the metal 34 also connects the two-terminal network thus formed to a region 37 of an IGFET. The diode-capacitor combination (21), Fig. 2 (not shown), is biased in the reverse direction of the diode and serves as a high resistance load for a control transistor (22) of the memory element. The temperature behaviour of the combinations (21) is matched to that of the transistors (22) to compensate the effects of temperature changes on the memory element.

Title: Magnetically settable counter
IPC: G11C19/10
Filed: 1966-10-26
Abstract: 1,130,198. Magnetics shift registers. UNITED STATES ATOMIC ENERGY COMMISSION. 26 Oct., 1966,[16 Nov., 1965], No. 47955/66. Heading H3B. [Also in Division H1] The input element of a magnetic counter or shift register fusing the moving magnetic domain principle is movable so that information can be written at a selected region of the storage medium. As shown the storage medium is a nickel-iron wire 10 wound spirally on a cylindrical substrate 40 and shift conductors 28, 30 connected to a two-phase clock are arranged in a meandering configuration around the substrate, so that they extend generally axially of the cylinder. The inner surface of the substrate 40 is provided with a spiral groove 44 corresponding in lead and pitch to the wire spiral 10, and a stem 48, again with the same lead and pitch, is provided on the axis of the cylinder A beryllium copper spring 50 surrounds the stem. Threaded on stem 48 is a write head assembly 61 carrying a nucleation coil 20 on a ferrite core, the core and coil extending into groove 44. The head assembly 61 also carries, in a pair of diametrically opposed slots, two toroidal cores (Fig. 6, not shown) having secondary windings connected in series with the nucleation coil 20. Two turns of spring 50 pass. through the apertures of the cores and form a primary winding for each core, energized from input source 18. The write head is rotated by shaft 96 attached to a knob 90, the thread on stem 48 causing the head to track along groove 44 as it is rotated. Data entered at a selected region eventually reaches output coil 22 wound round storage wire 10. Coil 24 is a bucking coil not wound round wire 10 and compensating for the effect of the shift conductors 28, 30. Since the currents in the shift conductors 28, 30 are favourable for entering data only once in each cycle the write head must always be moved to the same position relative to the shift conductors, i.e. if the input source is synchronized with the shift pulses for entering datawhen the headis adjacent a portion of conductor 28 in which current flows upwards then writing can only be accomplished adjacent such conductor portions. An index on knob 90 isco ordinated witha dial plate and calibrated to indicate the allowed positions and the count corresponding to each position. By moving the writing head the count required between data being entered and read can be varied. The time taken for a given count to be reached may be varied by changing the frequency ofthe shift pulses. An additional reading coil may be provided at the opposite end of wire 10 to determine the complement of the count determined by coil 22. Bias permanent magnets may be arranged at each end of wire 10 to keep it uniformly magnetized.

In operation depression of valve 16 allows air to pass to the motor and bleed via port 33 to chamber 34. As the motor picks up speed valve ball 42 is moved off its seat thus venting chamber 34. The ball does not move back on to its seat until the water stops. Build up of pressure in chamber 34 then occurs and valve 22 moves to a closed position. The control unit 30 is balanced.
