Filed: 1958-10-23
Abstract: 855,155. Nuclear reactors. METALLGESELLSCHAFT A.G. Oct. 23, 1958 [Nov. 8, 1957], No. 34007/58. Class 39(4). [Also in Group XXVI] Gaseous UF 6  is passed, at a density high enough to sustain a nuclear reaction, into a gas turbine which is driven by the heat produced in the reaction. Turbine parts in contact with UF 6  may be made or coated with Cu-Ni alloy, Cu, Ni, Be, BeO, Al 2 O 3 , MgO, or combinations of these. A graphite reflector 16 may be put round the reaction zone. This zone is followed by an expansion zone from which the gas returns to a two-stage compressor 2 driven by the turbine. An electric generator 7 and a starter 5 are coupled to the turbine and compressor by electro-magnetic clutches ; the plant is shut down by overloading the generator. In the gas return line 17 are a cyclone (not shown) and a distillation column (not shown) to remove fission products. The whole plant is in a gas-tight housing 18 inside which a temperature of about 70‹C. is maintained.

Title: Improvements in or relating to tubing
Inventor: DESMOND ERIC
IPC: B29C53/60
Filed: 1957-10-31
Abstract: 900,884. Flexible tubing. SMITH & SONS (ENGLAND) Ltd., S. Oct. 31, 1958 [Oct. 31, 1957], No. 34039/57. Class 99(2). Tubing, having at least one flexible non-metallic wall, is made by wrapping a helical metallic strip 1 on a mandrel 3 in overlapping convolutions to form a temporary supporting layer, the metallic strip being readily soluble in a solvent which does not act on the flexible material, helically wrapping strips of the flexible material 5 in overlapping convolutions, treating the tube to bond the overlapping flexible convolutions and dissolving out the temporary layer. The metallic layer may be of aluminium and the flexible material of p.v.c. or p.t.f.e. either of which may have glass fibre reinforcement. An outer temporary layer 22 may be applied. The composite tube 23, Fig. 2, is moved along the stationary mandrel 3 into a rotating ribbing and grooving tool 4 which forms coarse helical ribs in the region 9 which are further compressed axially by screw threads of finer pitch in region 10. After heat treatment in a refractory tube 24 of a gas-fired furnace 14 a solution of sodium hydroxide is circulated through the tubing 15 Fig. 3, by a pump 19 until the temporary layers are dissolved.

Abstract: 831,691. Pipe joints. LADISH CO. Nov. 7, 1956, No. 34051/56. Class 99(1). Pipes 8, 9. e.g. for sanitary systems, have end faces 14, 15 which have annular grooves 18, 19 to receive ribs 23, 24 on a hard resilient gasket 21 having a web portion 22 the diameter of the inner surface of which is greater than that of the bore of the pipes such that when sufficient axial compressive stress is applied to cause the ribs completely to fill the grooves, the web is deformed radially inwards so that the inner surface of the gasket lies flush with the bore of the tubes ; this avoids a recess at the joint. As shown, each groove comprises a circular part, diverging walls 30, 31 and a flared edge, the ribs 23, 24 are semi-circular and the web 22 is wedge-shaped the thickness being greater at 32 than at 21 so that when pressure is applied by means e.g. of a toggle-type split ring clamp 25 deformation of the gasket takes place and provides the sealing action.

Abstract: 1336930 Digital multipliers SINGER CO 21 July 1971 [28 July 1970] 34120/71 Heading G4A A multiplier is arranged in groups of two or more digits, the multiplicand is multiplied by the numerical value of each group of digits in corresponding stages of multiplication to form partial products, and in each stage the partial product is added to a partial sum and partial carry from the preceding stage after alignment of the respective digits to produce the partial sum and partial carry for that stage. The multiplier may be arranged in 2-bit groups as in Fig. 5. Each group of multiplier bits is decoded at 101, 102 to produce a partial product of 1, 2 or 3 Î the multiplicand, the latter multiple being produced by sending a carry 1 signal to the decoder of the next stage (equivalent to introducing 4 x the multiplicand) and passing on the 2's complement of the multiplicand to the next stage from gates 123-153 or 126-156. Since the multiplier groups are each of 2-bits in this embodiment, the partial product is shifted 1 or 2 places to the right, depending on the multiple selected, when it is passed on to the next stage. The final product is formed from the lowest 2-bits of the first stage partial product and the sum produced by the network of adders shown.

Abstract: 1516200 Transistor ramp voltage generating circuits TEKTRONIX Inc 27 Aug 1975 [7 Oct 1974] 35326/75 Heading H3T In a ramp generator, a capacitor 50 is charged from a constant current source 52 and subsequently discharged into a constant current sink 66 under control of a gating circuit (e.g. in the form of an emitter coupled pair of transmitters 62, 64). The voltage at the foot of the ramp is stabilized by a feedback circuit which compares the voltage with a reference Vref by means of an amplifier 58 which produces an error current which is fed to the capacitor 50. As described, initially, transistor 62 is turned off so that transistor 64 directs the charging current IT into the sink 66, the quiescent voltage across capacitor 50 being stabilized by feedback circuit including amplifiers 56 and 58 which compares the voltage with Vref. In order to generate a ramp, transistor 62 is turned on so as to turn off 64 and divert the constant current 52 into the capacitor 50. Diode 68 prevents saturation of transistor 62. Current Is should be much greater than I T .

Title: Improvements in machines for compressing and extruding or moulding substances
IPC: B30B3/04
Filed: 1929-11-20
Abstract: 344,003. Moulding cattle cakes &c. by rolling and extrusion machines. DRYDEN W., Grimshaw Street Foundry, Preston, Lancashire. Nov. 20, 1929, No. 35426. [Class 87 (ii).] Relates to machines for compressing and extruding or moulding cattle cakes &c., of the kind set forth in Specifications 269,612 and 276,896, [both in Class 87 (ii), Moulding plastic &c. substances], and consists in mounting the shaft of the extrusion die B, Fig. 4, in bearings which lie wholly on one side of the die, thereby allowing the compression member C to be formed with a hollow shaft C<1> through which tailings leaking between the die and the compressing member may escape. The bearings for the die shaft and the compressing shaft may be arranged to be interchangeable. The die shaft is carried by a fixed head, the compressing shaft being mounted in a head E which may be moved on the bed A<1> by a hand-wheel 3 for repair purposes, but which is held in working position by tie rods F coupled to the die shaft head, to prevent the transmission of strain to the bed. In a modification, the member C may also be perforated, a loose washer being mounted between B and C so that material is extruded in both axial directions. In a further modification the members B and C are duplicated at each end of the machine a central drive being transmitted to the shaft carrying the two members B. The members B and C<1> may be provided with mould cavities on their opposed faces. When the cattle cakes &c. are formed by extrusion, the extruded streams are severed by a fixed knife pressed against the rear face of the disc member B. The member C may be provided with a renewable working face. The member B is secured on its shaft by a nut which has a ring of internal teeth at its outer end adapted to engage with similar teeth on a looking plate adapted to be bolted at any desired angular position on the end of the shaft. Shields adjustably carried by the rods F project inwards and engage the peripheral surfaces of the members B and C to prevent lateral escape of material. The length of the extruded stream is controlled by a stop plate V, Fig. 11, whose distance from the rear face b<11> of the member B is regulated by nuts V<4>. Specifications 245,286 and 285,529, [both in Class 87 (ii), Moulding plastic &c. substances], also are referred to.

Abstract: 956,924. Grinding rods. NYDALS GJUTERI OCH MEKANISKA VERKSTAD A.B. Sept. 18, 1962 [Sept. 18, 1961], No. 35556/62. Headings B3D. A rod 1 is ground or polished by rotating it about its axis and feeding it axially into engagement with a grinding or polishing member 4, each momentary rod-engaging part of which is caused to move substantially parallel to the axis of the rod at a considerably greater speed than that of the axial advance of the rod and has a speed component which is directed subst antially perpendicular to the rod and is of substantially the same magnitude and disposed in the same direction as the circumferential speed of the rod at the contacting area; each part of the member 4 while in momentary engagement with the rod grinds or polishes along a path which is longer than the distance the rod is moved axially during each of its revolutions. The rod 1 is supported by a roller 2 and rotated by rollers 3 which are slightly skewed to feed the rod to the grinding member 4 which may be a disc or an abrasive belt passing over a contact wheel. Opposite the member 4 are supporting rollers 5 which may be replaced by a second grinding member acting similarly to the member 4. The above-mentioned speed component of the member 4 acting perpendicularly to the rod is provided by skewing the member 4 at a slight angle to the rod. If desired, the member 4 may be intermittently or continuously moved transversely across the rod during the operation and its width is then arranged to be greater than the diameter of the rod; alternatively, the rod 1 may be moved transversely relatively to the grinding member or the same effect obtained by moving both members.

Title: Apparatus for testing delay units
IPC: H03K5/26
Filed: 1971-05-04
Abstract: 1338241 Testing delay units MARCONI CO Ltd 4 May 1971 [23 July 1970] 35771/70 Heading G1U In order to test a delay unit 1, Fig. 1, a pulse is applied simultaneously both to it and to two other delay units 2, 3 accurately adjusted to have delays corresponding to the upper and lower tolerances appropriate to the delay unit under test, and means are provided for determining whether the pulse eventually emitted by the delay unit under test occurs within or outside the tolerance range. As described a 'one' signal is normally applied to all three delay units by a bistable circuit 6, 7 causing, as a result, the signal combination '1, 0' to be applied to the upper and lower inputs respectively of two triggers 14, 15. In operation a push-button 10 is momentarily depressed to change the state of bistable circuit 6, 7 causing a 'zero' to be entered into all three delay units and causing the triggers 14, 15 each to assume the signal condition applied to their inputs namely 1,0. The triggers 14, 15 are such that when a 'zero' signal is applied to their central inputs 23, 24 respectively, they assume as their stable conditions, states corresponding to the signal combinations applied to them by delay units 2 and 3. Thus, if the delay unit under test produces a 'zero' output in response to the 'zero' input before the lower threshold delay 2 does,  then neither trigger 14, 15 changes its state, their states remaining 1,0. However, if the 'zero' output from the delay unit under test occurs after that from the lower threshold delay 2, then it will find the signal combination 0,1 applied to trigger 14, which as a result, will change its state to produce a 0,1 signal combination output. Similarly, if the output from the delay unit under test occurs after that from the upper tolerance delay 15, then both triggers change their states. The output signals from triggers 14 and 15 are decoded by NAND gates 27, 28, 29 to control lamps indicating "too short", "too long" and "OK", gates 27, 28, 29 normally being inhibited by a 'one' signal from the delay unit under test.

Abstract: 870,524. Suction lifting devices. UNILEVER Ltd. Nov. 7, 1958 [Nov. 12, 1957], No. 35887/58. Class 78 (4). Each suction port 17 (Fig. 2), of a suctionlifting manifold 19 has a normally open valve which seats if vacuum is applied to the manifold while the port is not engaging the article lifted, and which provides a restricted connection between the manifold and the port. In the construction of Fig. 2, the valve 21 normally rests on fingers 24 on a flexible grommet 22 and allows air to pass freely so that suction is applied to the article lifted. If, however, the article does not engage the grommet 22 the passage of air is sufficiently rapid to raise the valve 21 into engagement with a flexible seat 20 where it is held by suction. Should the article subsequently seal the grommet 22 an aperture 30 in the valve 21 allows the pressures across the valve to be equalized so that the valve falls to its open position. A spring may bias the valve 21 away from its seat. In the alternative construction of Fig. 3 the valve 21<SP>1</SP> is mounted freely between upper and lower flanges 28, 29 on a grommet 25 surrounding the aperture 17<SP>1</SP>. The grommet 25 may be replaced by resilient apertured sheets secured one above, and one below, the bottom 19<SP>1</SP> of the device.
