Title: Improvements in and relating to superconductive elements and circuits employing same
IPC: G11C11/44
Filed: 1960-11-08
Abstract: 908,541. Super-conductor circuits. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORPORATION. Nov. 8, 1960 [Nov. 24, 1959; Dec. 16, 1959], No. 38396/60. Class 40 (9). [Also in Group XXXVI] A super-conducting switching or memory element formed to have at least one electrically symmetrical axis is provided with a pair of input terminals and a further pair on the symmetrical axis so that the transition between the super-conducting and sensitive state may be achieved by signals applied to both pairs of terminals. Fig. 3 shows a loop of superconducting material such as a filament or film of tin lead, tantalum or niobium, to terminals A, B of which a current 2I 0  is applied. The current is less than the critical current Ic at the operating temperature of the device. A further current 2I 1  is applied across terminal C, D possibly in the form of a pulse. This current divides itself equally in the two branches CAD and CBD while 2I 0  divides itself into two currents I 0  in branches ABC and ADB. In section AD the currents are additive and section AD and CB become resistive and an output voltage will appear between terminals CD. Fig. 5 shows an arrangement in which triggering of the first of a number of similar circuits I to the resistive state produces a voltage across terminals CD which triggers the second and so on. In a still further arrangement (Fig. 6, not shown) the output of each device is inductively coupled through a superconducting device to the input of the next. The superconductor device may be square with terminals at the middle of the sides or with holes in the centre (Figs. 12-16, not shown) or as shown in Fig. 17 may be geometrically asymmetrical but electrically symmetrical. A device may be so constituted (Figs. 8a, 8b, not shown) as to be supplied from a number of sources (e.g. three) most of which must be feeding the device if it is to trigger. Fig. 20 shows a construction of memory device. In this case terminals CD are not on the horizontal axis. Initially section AD becomes resistive. As the current applied at CD increases this all flows through superconductive branch CBD which in turn becomes resistive. By consideration of the state of affairs when AD is resistive but CBD is not the Specification shows that on the removal of the current applied to CD the circuit will return to the superconductive state and a circulating current will remain in the loop. By reversing the current applied to CD the direction of the circulating current will reverse. A read-out current applied between terminals CD will produce a more or less sharp pulse between terminals AB. Fig. 26 shows a construction in which the read-out terminals are separate from the write-in. Fig. 28 shows a combined switching element X and memory element Y.

Abstract: 1,070,035. Latch fastenings. "SOCIETE D' ETUDES & DE RECHERCHES TECHNIQUES" (S.E.R.T.). Sept. 23, 1964 [Sept. 25, 1963], No. 38749/64. Heading E2A. In a mechanism for latching vehicle doors, an energy storage device comprises a blade spring 21 which is loaded by an arm 16 pushing a leaf 19 solely under the closing action of the door. When the door is very nearly closed, the leaf 19 pushes a slide 28 to cause a pawl 23 to release a second leaf 18 whereupon the spring 21 urges upward a rod 8. A stop 30 rises to contact the arm 16 behind a block 31 to hold the arm, Fig. 6 (not shown). The upward movement of the rod 8 causes a piston (39); Fig. 7 (not shown) to force hydraulic fluid from a cylinder (38) to a cylinder (44) thereby pushing a ball (47), mounted on a latch bolt (46), into engagement with a keeper on the door post, Fig. 8 (not shown). An annular shoulder (54) on the keeper cooperates with an opening (55) on the end of cylinder- (44) to provide an antiburst device. An inner door handle (13) releases the stop 30 and opens a ball valve (58), Fig. 7 (not shown), enabling the door to be opened and the mechanism to return to its initial condition. A childsafety lock may be incorporated. The motion transmitting means may be solely mechanical or solely hydraulic.

Filed: 1959-11-17
Abstract: 884,434. Shaft couplings. BOSCH G.m.b.H., ROBERT. Nov. 17, 1959 [Nov. 29, 1958], No. 38920/59. Class 80 (2). A coupling between shafts 3, 4 which is susceptible to adjustment by hydraulic pressure to vary the angular relationship between the shafts, for use, in, e.g., the drive to an engine fuel injection pump, comprises disc-like flanges 6, 8 fast with the shaft 3 and carrying webs 7 supporting pivotally the flanges 11 of segments 9 having similar flanges 12 pivoted in a hub on the shaft 4, a compressed spring 17 engaging the segments to bias them away from each other and hence turn the shafts 3, 4 in one direction relatively to each other, while hydraulic pressure in a surrounding casing 1 opposes the spring bias and tends to move the segments inwards, thereby turning the shafts in the opposite direction relatively to each other. The flanges 11, 12 on the segments 9 are mounted in partcylindrical journals 13, 14 carried by the webs 7 and the hub of the shaft 4, respectively. Oil is drawn from a sump 25 by a pump 24 and supplied through a pipe 23 having a by-pass 26 with a restriction 27 therein to a port 22 leading to a space 21 in the casing 1 surrounding the coupling. Oil leaking from the space 21 past the segments 9 to the space containing the spring 17 and round the shaft 4 passes through ports &c. 30, 29, 28, 32, 34 to a pipe 35 vented to the sump 25. With increasing speed, the corresponding increase in pressure produced by the pump 24 forces the segments 9 inwards against the bias of the spring 17 and against the effect of centrifugal force.

Abstract: 951,877. Magazine slide changing apparatus. ERNST LEITZ G. m. b. H. Oct. 16, 1962 [Nov. 2, 1961], No. 39093/62. Heading G2J. Magazine slide changing apparatus comprises a slider 1 movable into and out of the projection position on guide rod 2 by a handgrip 3 which may also be operated to transport the magazine 6 and to perform another control function such as focusing the objective. Rack 9 on magazine 6 is engaged by toothed wheel 11 mounted on bracket 10 of slider 1 and meshing with indexing wheel 12 rotatable by shaft 13 through handgrip knob 3. When slider 1 is moved to the projection position with slide 7, pinion 15 engages lever 16 and may be rotated by knob 3 to focus lens 19. In a modification, the slide movement and magazine transport are carried out in a single movement of knob 3, the shaft 13 being rockable about its lower bearing to position "b" when a further toothed wheel 22 fixed on the shaft is rotated through one tooth space by pawl 24 which cannot yield. This rotation advances magazine 6 by means of wheels 11, 12. As shaft 13 is returned to position "a", spring- loaded pawl 24 yields. In a further modification, shaft 13 carries a single toothed wheel 28 which drives rack 9 in position "A" and which engages another wheel 29 in position "B" to control focusing, for example. The shaft is also axially displaceable downwards to engage friction wheel 30 with rail 31 to control a further projector function (e.g. control of a diaphragm or luminosity of the projector lamp), the wheel 28 then being disengaged from rack 9 or wheel 29. This disengagement may be avoided by placing wheel 34 on a sleeve carrying knob 3 which is coupled to shaft 13 by an internal gear which disengages when knob 3 is depressed.

Abstract: 1518717 Automatic position control TELDIX GmbH 21 Sept 1976 [7 Oct 1975]  39166/76 Heading G3R A magnetic bearing arrangement includes a rotor position sensor and a generator connected to the rotor and producing a signal having a frequency corresponding to the rotor speed. The generator signal is combined with the sensor signal in order to compensate or remove error components synchronous with the rotation. The resulting signal is supplied to coils which control the rotor position. As shown, a bearing arrangement includes a stator 2 and a rotor 1, each carrying permanent magnet rings 4, 5, 6, 7, and ferromagnetic rings 10, 11. The axial position of the rotor is controlled by a closed loop formed by a position sensor 20, control device 21 and an annular winding 16 or 16a. An inductive sensor 26 detects the radial position of the rotor and feeds a signal into a mixer 30 which also receives a signal from an inductive generator 27 including a winding 28 on the stator and a permanent magnet 29 mounted on the rotor. The synchronous signal from the generator 27 can be pre-set to a given phase relationship with the signal from sensor 26 or may be shifted to a desired phase in the mixer 30. A resulting compensated signal is fed to a controller 31 which energizes four control coils 25 to regulate the radial position of the rotor. A circuit 33 measures the current and voltage of the coils 25 and adjusts the desired position set in the controller 31 so as to minimize the power taken in the coils 25.

Abstract: 1282866 Treating glass surfaces PILKING- TON BROS Ltd D G LOUKES and A EDWARDS 6 Aug 1969 [16 Aug 1968] 39367/68 Heading C1M To produce glass having desired surface characteristics, particularly for colouring the glass or to give an electrically conductive surface film, the glass at, or heated to, a temperature at which it is susceptible to surface modification has directed thereon a metal compound in vapour form under oxidizing conditions which are regulated to promote oxidation of the metal compound at the glass surface only, and to produce the metal oxide as it is dissolved into a surface layer of the glass without just existing in isolated phase. Rolled or pressed glass can be so treated but the apparatus disclosed relates to float glass only. Silica glass may be treated and shapes referred to are flat, curved or profiled sheets, TV face panels and building blocks. Metals suggested are Na, K, Sb, Bi, Pb, Sn, Cu, Co, Mn, Cr, Fe, Ni, Si or Ti or alloys thereof, Co-Cr and Na-Bi being mentioned. A reactive gas, particularly chlorine (with nitrogen) or oxygen for tin (giving stannous oxide vapour) is passed over the metal either in solid or molten form and oxygen (with nitrogen) either added to the reactive gas or directed separately at the glass surface. Subsequently, the oxide in the surface may be reduced by passing through a nitrogen atmosphere with e.g. 1% hydrogen added. As shown in Fig. 4, float glass 30 on molten tin 10 passes under a bar stretching across the full width of the bath of tin. The bar may be wholly of the metal or part 44 of metal and part 45 of a refractory material. A reactive gas passes through the space between the bar 44 and the surface 38 of the glass from a tube 34 and the oxidizing gas is introduced through the bar 45 at 46. A tube 40 is connected to vacuum to exhaust the gases. As in Fig. 5, reactive gas from tube 54 is passed over a boat 51 with molten metal 52 under an enclosure 52 with leading wall 55 adjacent to the glass surface. Oxygen and nitrogen is introduced from a slot 57 in tube 56 and exhaust gases removed by tube 61. As in Fig. 6, the enclosure 60a is tubular and forms also exhaust tubes 61a, 62, the metal compound in vapour form being introduced by a central tube 66 with slot 67 and oxygen and nitrogen fin tubes 73, 74 with slots 75, 76 angled towards the central tube.
