Title: Transistor memory circuit
IPC: H03K3/2885
Filed: 1971-09-22
Abstract: 1348327 Transistor bi-stable circuits INTERNATIONAL BUSINESS MACHINES CORP 22 Sept 1971 [30 Oct 1970] 44102/71 Heading H3T [Also in Division G4] A transistor memory comprises a plurality of memory cells each including a pair of crosscoupled dual emitter transistors, one emitter of each transistor being connected to receive a constant bias voltage, a plurality of sense circuits each associated with at least one memory cell, and network means interconnecting the memory cells and the sense circuits such that each cell and its associated sense circuit operate together in a current switch mode. By "current switch mode" is meant operation where a substantially constant current flows through either one of two emitter-coupled transistors depending on which transistor base is at the higher level, the current being insufficient to saturate the transistor through which it flows, (see Specification 872,251). The memory consists of a matrix of bi-stable transistor cells connected to sense circuits via double column lines 23, 24, 25, and 26. The Specification describes the construction and operation of the memory and associated row and column select circuits in some detail, the majority of the circuits used being adapted to operate in a current switch mode. Briefly the sense circuit transistors T26, T27, and T28 together with the left hand transistors T8, T15 in the associated column, and the sense circuit transistors T23, T30, and T31 together with the right hand transistors T9, T16 in the associated column are emitter coupled so as to operate in a current switch mode. The constant current supplied via resistors R17 and R28 may be switched through the corresponding storage transistors, e.g. T8 and T9, in order to write a "1" or a "0" in a cell, the particular cell in a column being selected by row select circuits via line 16. Read out is by detecting the column line in which current is flowing.

Title: Improvements in or relating to methods and apparatus for coating tube interiors
IPC: C23C6/00
Filed: 1959-12-30
Abstract: 896,629. Coating with metals; alloys. BUNDY TUBING CO. Dec. 30, 1959 [Dec. 31, 1958], No. 44221/59. Classes 82(1) and 82(2). The interior of a tube is coated with an alloy that has plastic properties in a range of temperatures between its melting and freezing points by introducing molten alloy into the tube interior, distributing said alloy over the interior surface of the tube before the alloy has cooled to below said range of temperatures, and then cooling said alloy so as to solidify it. In operation of the apparatus shown, tube T is introduced through guide 30 between rolls 20-23 which spin the tube about its longitudinal axis and advance it to the left. Magnetic proximity switch 41 is actuated when the tube approaches it and stops the drive for the rolls, releases timer 42 and energizes relays 45, 46 for closing switches 43, 44. The tube remains at rest for a period determined by timer 42 and during this period the portion of the tube between rolls 26, 27 and 13, 14 is heated by passage of current from transformer 32. When timer 42 times out, rolls 20-29 are actuated for moving the tube to the right. Simultaneously, valve 7 is opened so as to spray molten alloy on to the interior of the tube from nozzles 9, this alloy being derived through pipes 6, 8 from vessel 1 by operation of pump 4. Enlargement 12 on pipe 8 smoothes the coating while it is still plastic, and coolant 36 emitted from pipe 37 then rapidly solidifies the coating. Proximity switch 39 stops operation of the apparatus. Suitable coating alloys are Sn 99%, A1 1%; Sn 90-99%, Cd 1-10%; Sn 95%, Sb 5%; and Zn 95%, Sn 5%.

Title: Improvements in and relating to printing tapered articles by heat transfer
IPC: B41M1/40
Filed: 1965-10-21
Abstract: 1,056,739. Transferring designs. DENNISON MANUFACTURING CO. Ltd. Oct. 21, 1965 [Dec 11, 1964], No. 44619/65. Heading B6C. Articles, such as plastic bottles B having a conical surface, are labelled by transferring inked indicia from a printed strip S to the conical surface by hot pressing with the raised part 17 of a rotating iron 1, the strip being fed during transfer at a predetermined speed and in a direction transverse to the article axis, and the article being rotated about its axis at a speed such that its velocity where it contacts the longitudinal medial line of the strip is equal to that of the strip, its surface velocity being correspondingly lesser and greater towards the small and large ends of the conical surface. The strip has a base coating of wax, and a thermoplastic ink is used having a higher melting point than the wax. During the hot pressing, the ink is not melted but merely made tacky so that it adheres to the article, and the base coating is heated to the point where slippage due to the difference in speed between the article surface and the strips at positions other than the medial line occurs in the coating. This causes the transferred indicia to be contracted and expanded above and below the medial line (Fig. 4, not shown). The machine employed is generally similar to those described in Specifications 937,071 and 954,054 and comprises a table 41, Fig. 6 (not shown), to which the articles are fed one by one from a supply shoot 13 by an intermittently rotating turret 16 and from which they are passed to a delivery shoot 14 by the turret. The table 41 has an opening 43 at the marking station into which the articles are successively moved to seat on a rotor 44 which rotates the article B about its axis during marking. The article is pressed against the rotor 44 by a nozzle 62 which may serve to inflate it during marking. The indicia-carrying strip S is fed from a supply roll 2 by a sprocket 12 engaging perforations therein and passes over guide rollers 9 to a wind-up roll 3. The rollers 9 are mounted on a carriage 11 reciprocated so as to cause the portion of the strip adjacent to the marking station to be stationary whilst the turret is rotating, and to be forwarded at the required speed during marking. The table 41 and turret 16, however, are not horizontal as in the prior machines, but are inclined so that the line 9 contact between the article and the strip is vertical.

Abstract: 1347078 Aerials; radar; transponder apparatus INTERNATIONAL STANDARD ELECTRIC CORP 30 Sept 1971 [8 Oct 1970] 45538/71 Headings H4A H4D and H4L A beacon for use in conjunction with coherent pulse Doppler radars is arranged to retransmit signals which have polarizations corresponding to those of received signals. An aerial system is provided which has two orthogonally polarized components. As described (Fig. 3, not shown) twelve lengths of waveguide are placed side-byside with their upper faces lying in a common plane. Said upper faces each carry an array of parallel dipoles or of slots which are disposed at - 45 degrees to the waveguide axis in odd-numbered waveguides, and at +45 degrees to the waveguide axis in even-numbered waveguides. A series of couplers connects the odd-numbered waveguides to a terminal G, and another series of couplers connects the even numbered waveguides to a terminal D. The said terminals are connected through respective pairs of directional couplers 8, 10 and 9, 11, Fig. 2, and respective electronically controlled phase shifters 16, 17 to respective short circuits 18, 19. The directional couplers 8, 9 apply small portions of the received energies through respective amplifier/ detectors 12, 13 to first and second inputs H1, H2 of a logic circuit 21. The directional couplers 10, 11 are connected to the inputs of a hybrid junction 20, the outputs B, A of which are connected through respective amplifier/detectors 14, 15 to third and fourth inputs H3, H4 of the logic circuit 21. A circuit 25 is connected to the outputs (five) of the logic circuit 21 and controls the operations of two sawtooth generators 22, 23 associated with respective phase shifters 16, 17. The relative phases of the received energies at the array terminals D, G depend upon the kind of polarization of the impinging waves, being in phase for vertical polarization, in anti-phase for horizontal polarization, and in quadrature for circular polarization. The hybrid junction 20 provides respectively to its outputs A, B signals in phase and in anti-phase with respect to the input signals. With equal in phase inputs, there is output only at A. If the inputs are in anti-phase, there is output only at B. If the inputs are in quadrature, there are outputs both at A and B. The phase shifters 16, 17 have ranges of 0 to # and, since they are traversed twice by the signals provide a maximum phase change of 2#. They are not operated unless the received signals exceed a predetermined threshold value. The sawtooth repetition frequency represents a Doppler frequency which is assigned to the particular beacon. The following table shows whether there are (1), or are not (0), signals to the inputs of the logic circuit 21 for the various received polarizations, and which of the sawtooth generators 22, 23 are operated With circular polarization it is arranged that the re-transmitted waves are of opposite hand from that of the received waves.

Abstract: 1, 098, 854. Rotary-piston internal combustion engines. R. BOOCOCK AND A.J. MATHEWS. Nov. 18, 1964 [Nov. 19, 1963; Jan.31, 1964], Nos.45576/63 and 4117/64. Heading F1F. A rotary-piston I. C. engine using either spark (or compression) ignition, comprises rotors A, B mounted for rotation in the same direction in respective cylindrical casings A2, B2 on parallel shafts A1, B1. Each piston includes identical lobe portions A3, B3 and heel portions A4, B4 which co-operate with outwardly sliding abutments G1, G3 and a common abutment G2. In the Figure, exhaust of burnt gases through port EPA is almost complete, air-fuel mixture is being sucked in through port IPA to casing A2 below the abutments G1, G2, gas expansion in casing B below abutments G2, G3 is complete and exhaust of burnt gases has commenced through port EPB, and sucking of air-fuel mixture through port IPB has just commenced. The compression of a previous charge has been completed above the abutment G3 in casing B2 and this charge is being transferred through passage TPB, where it is fired by a plug S into casing A2. On further rotation of the pistons, the port EPA and transfer passage TPB are closed so that compression of the charge in casing A2 below abutments G1, G2 commences as also does expansion above abutment G2. In casing B2, exhaust below abutments G2, G3 and suction above abutment G3 continues. On rotation of the pistons through 180‹, compression in casing A2 below abutments G1, G2 is completed and the charge is fired in passage TPA and transferred to casing B2. At the same time full expansion of a previous charge has taken place in casing A2 above abutments G1, G2, and suction and exhaust above and below abutments G2, G3 in casing B2 are almost complete. Thus each piston in one complete revolution carries out the four phases of suction, compression, expansion and exhaust. The abutments Gl, G2, G3 are preferably actuated by a ring cam synchronized with rotation of the pistons to give positive movement to the abutments. Small vanes or other seals may be provided either on the pistons or in the casing walls. The shape of the pistons may vary according to engine requirements such as the type of fuel being used, ignition means or compression ratio. In an inline arrangement of pistons the assymmetrically positioned single lobes on each piston will require balancing. The pistons may be mounted coaxial with the pistons 180‹ out of phase to thereby balance the pistons. In another embodiment, each piston has three lobes resulting in six firings per revolution. The pistons in this instance will be naturally balanced. Any desired number of paired pistons may be mounted on the same output shaft in the same or separate housings.
