Title: Sleeve pressing machine
IPC: D06F71/28
Filed: 1961-04-18
Abstract: 916,108. Ironing presses. McGKAW-EDISON CO. April 18, 1961 [April 22, 1960], No. 13913/61. Class 138 (2). In a sleeve-pressing machine two bucks 35 fitted with inflatable porous bags 37, are mounted upon a pivot tube 31 and are moved by an air motor 38 from a dressing position (as shown) to a pressing position between pairs of pressing platens 58 whilst the pressure of heated air being supplied to the bucks through tubes 33 is automatically increased. The platens are mounted on arms 56 having pivots 57 and each pair is moved towards the associated buck by an air motor 63 pushing a wedgecam 68 between rollers 69. Position-compensating springs are provided at the rear of each platen (Fig. 5, not shown), and spring means (not shown) are used to restore the platens to their open position; spring means (Fig. 2, not shown) are also provided to return the bucks to their dressing position. As illustrated in Fig. 6, air is supplied to the air motor 38 by a source 43 through a pressure regulator 45, a filter 46 and a solenoid-operated valve 44 having an exhaust device 48. When the piston 65 moves the bucks to their pressing position by means of a piston rod 40, it opens a port 66 to admit air to the motors 63 and causes the platens to move towards the bucks, air being discharged from the motors 63 through a check valve 89 when the valve 44 is opened. Air is supplied to the bucks by a pump 70 through a manifold 74, a conduit 76 and a heat exchanger 17 fitted with a steam heated coil 80. A butterfly-valve 83 operated by an air motor 85 receiving air from the motor 38, is open to permit a proportion of the air to return to the pump 70 from the manifold 74 while the bucks are in their dressing position and is then closed to raise the pressure of the air supplied to the bucks as they move to their pressing position. A solenoid 51 operating the valve 44 may be opened and closed by means of push-buttons 49, 52, respectively, or by means of the pushbutton 49 and a timer device (not shown), the timer device serving to de-energize the solenoid and close the valve 44 after a pre-determined period of time. The platens may be heated by passage of steam through chambers included in the platens (Fig. 5, not shown).

Title: Improvements in electric valve systems for controlling welding and other circuits
IPC: B23K11/24
Filed: 1940-09-09
Abstract: 543,747. Control systems for resistance welding &c. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 9, 1940, No. 14027. Convention date, Sept. 8, 1939. [Class 38 (iv)] [Also in Group XL] Thermionic stud like control; capacitative control.-Means for periodic energization of a load circuit from an A.C. supply, such as for an interrupted series of spot welds, is arranged so that the periods of energization and de-energization and the number of energization periods are independently directable. Two reversely connected valves 4, 5 in series with a transformer supplying a welding circuit 1 are controlled by valves 12, 13 the second of which is energized as a trailer on the energization of valve 12. A timing impedance applied to the grid of the valve 12 depends upon a condenser 45 the potential of which is opposed to an adjustable potential from a D.C. voltage director 41 at a contact 43, the position of which determines the duration of each energization of the load circuit. The condenser 45 is charged from the D.C. source through a circuit of adjustable time constant and periodically discharged by an auxiliary gas-filled valve or inverter 50 in series with an inductance 56 associated with glow discharge valves 59, 60 whereby the complete discharge of this condenser is always effected and the timing impulse maintained constant in magnitude and duration. The length of each period of de-energization is determined by a positive bias voltage on the grid of the valve 50 determined by the contact 77 on a potentiometer which voltage is ineffective so long as a charge is maintained on a condenser 70 by impulses derived from the load circuit by a transformer 71 and rectifier 73 and afterwards until this charge has fallen to a predetermined value. To start the inverter 50 peaky impulses are injected into its grid circuit by a transformer 75 supplied from the A.C. circuit. The number of successive energizations of the load circuit is controlled by a contact 91 on a potentiometer in series with a condenser 87 in the grid circuit of a valve 80 which when rendered conductive applies a negative potential to an electrode 54 of the inverter 50 to prevent its further action ;  the condenser 87 is charged with equal increments at each impulse from the inverter. The system shown is started by a switch 61 after preparatory closure of a main switch 2 and the control circuits of immersion ignition electrodes in the valves 4, 5 ; it is stopped by a pushbutton 62.

Title: Improvements in television camera circuits
IPC: H04N5/235
Filed: 1961-04-19
Abstract: 968,100. Controlling television camera tubes; pulse clipping circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 19, 1961 [April 22, 1960], No. 14152/61. Headings H3T, H4F and H4T. In a circuit for controlling the sensitivity of a television camera tube V, the video output signal of the tube is applied via a variable threshold stage T3 to control the resistance of a stage T4 which functions as a variable leakage path for an integrating circuit C1, R2, the resulting voltage across the integrating circuit being applied to the target of the tube via resistor R3. The time constant of C1, R2 is made equal to at least one television frame period and preferably much longer so that the voltage applied to the tube target is proportional to the mean value by which the video signal exceeds the threshold level set by stage T3. The threshold level is made adjustable by potentiometer R1. A Zener diode Z limits the maximum potential applied to the camera tube target when the signal level is low. Stage T1 is an emitter follower; stage T2 is a damp stage which is rendered conductive by blanking signals applied at B. The valve in stage T4 may be replaced by a transistor.

Title: Process for the recovery of gases enriched in hydrocarbons having two or more carbon atoms from gases having a low content thereof
IPC: C07C7/11
Filed: 1956-05-07
Abstract: Gases enriched in hydrocarbons having two or more carbon atoms are obtained from gases having a low content of these hydrocarbons by absorbing the hydrocarbons in a liquid solvent, expelling the hydrocarbons by heat or expansion and further concentrating the expelled gas by absorption on active carbon.  The process is suitable for recovering ethylene.  Benzene is the preferred solvent, the gas being absorbed under pressure and the pressure released in stages. The product from the first two stages, e.g. down to atmospheric pressure also contains undesirable gases and is concentrated by active carbon.  Gases obtained by further reduction of pressure need no further concentration.
Patent GB-771346-A (GB)
Title: A process for preparing trihydric alcohols
Filed: 1955-05-18
Abstract: A trihydric alcohol having not more than 4 carbon atoms in its molecule is obtained by hydroxylating a "corresponding" unsaturated monohydric alcohol with hydrogen peroxide in an aqueous medium and in the presence of formic acid, and thereafter removing formic acid from the reaction mixture by distillation in the presence of excess of the unsaturated alcohol calculated with respect to the formic acid and polyhydric alcohol formate content of the mixture.  A "corresponding" unsaturated monohydric alcohol is one having an olefinic bond between two carbon atoms neither of which carries a hydroxyl group.  The formic acid supplied to the process may be wholly or partly in the form of its ester with the unsaturated alcohol and the distillation may be carried out at atmospheric or higher pressure.  The formic acid ester removed from the reaction mixture may be used as starting material in a fresh hydroxylation since in aqueous solution it splits into formic acid and unsaturated alcohol.  In the examples: (a) allyl formate and hydrogen peroxide solution are heated under reflux until all the hydrogen peroxide is consumed; allyl alcohol and hydrochloric acid are added and the mixture is distilled to give glycerol. 2-methyl glycerol or 1-methyl glycerol may be obtained similarly from methallyl alcohol and crotyl alcohol or methyl vinyl carbinol respectively.

Abstract: 1,196,834. Semi-conductor devices. HITACHI Ltd. 26 March, 1968 [29 March, 1967], Nov., 14541/68. Heading H1K. An electrode applied to a surface of a semiconductor wafer 22 having an insulating covering 32 comprises an Al layer 34 contacting the substrate surface and extending across the insulation 32, a layer 38 of a refractory metal; i.e. Mo, Cr, Ti, W or Ta; also extending across the insulation 32 and contacting the A1 layer 34, and a further metal layer 42; e.g. of Ag. Au, Ni or Cu: in contact with the layer 38. The refractory metal layer 38 is, in general, less finely shaped than the A1 layer 34, since it is less easily etched into detailed configurations. Thus in the Si transistor shown the A1 layer 34 forms a comb-like base electrode interdigitated with a similar comb-like A1 emitter electrode 36 connected to a series of strip-like emitter regions and on which are provided a relatively large-area rectangular refractory metal layer 40 and a further metal layer 44. The layer 38 is similarly relatively large and rectangular. If the layers 42, 44 are of Au, an Au wire may be thermo-compression bonded thereto. If Ni is used for the layers 42, 44 a solder terminal may be applied thereto, e.g. by dipping. The layers 42, 44 may be positioned so as not to overlie directly the A1 layers 34, 36 (Fig. 8B, not shown). The insulating layer may be of silicon oxide. In further embodiments a second insulating layer (67), Figs. 3C-3F (not shown), e.g. of silicon oxide or nitride or of glass, is applied over the A1 layers (64, 66), and the refractory metal layers (68, 70) are deposited through apertures (69, 71) etched in the layer (67) to overlie parts of the A1 layers (64, 66) and of the first insulating layer (62). The further metal layers (72, 74) are then applied and connection made thereto by thermo-compression bonding or soldering as described above. A final embodiment is described in which the refractory metal layers (110, 112), Figs. 10A- 10D (not shown), are initially applied directly to the unbroken first insulating layer (108), following which apertures are etched through the layer (108) to the active surface of the wafer (102) and the A1 layers (114, 116) are applied to contact both the exposed wafer surface and the refrac. tory metal layers (110, 112) and to overlie parts of the insulation (108). A second insulating layer (118) is deposited, apertures exposing parts of the refractory metal layers (110, 112) are etched therein and Ni layers (124, 126) are deposited in these apertures. Finally the wafer is dipped in solder to apply terminals (128, 130) to the Ni layers (124, 126).
