Abstract: 1285560 Automatic voltage and current control WENTGATE ENG Ltd and R E TRILLWOOD 8 Oct 1969 [15 Oct 1968] 48781/68 Heading G3R [Also in Division H1] Electron beam welding apparatus comprises a filament 11 producing an electron beam directed through a magnetic lens 15 on to a workpiece 16, the voltage applied between members 11, 16 being maintained at a desired valve by a control loop which varies the firing angle of a thyristor 31 in series with the primary winding of a high voltage transformer 25. The control loop comprises an amplifier 27 receiving an error signal derived from comparison of a signal from voltage divider 22 with a reference signal 26, a bi-stable trigger circuit 28 receiving the amplifier output and a ramp waveform produced by a circuit 29, and a differentiator 30 producing the firing pulses for the thyristor 31. Stabilization of the beam current is provided by a control loop comprising current sensing resistor 33, reference circuit 34, amplifier 35, bi-stable trigger circuit 36, differentiator 37 and a thyristor or Triac 38 controlling the power supply 39 for a bias electrode 12. Sensing resistor 33 also controls an overload cutout 40 which switches off the thyristor 31 if the beam current becomes excessive. A programme circuit 41 determines the rate of increase and decrease of beam current and the duration of the welding current. Filament 11 is supplied by a circuit comprising an A. C. voltage stabilizer 21 and an auto-transformer 20 feeding A. C. to the supply 18. Various operating conditions of the apparatus are discussed.

Abstract: 1,163,116. Mangling and wringing apparatus. KODAK Ltd. 18 Nov., 1966 [18 Nov., 1965], No. 48991/65. Heading D1L. [Also in Division G2] A pair of rollers 22, 23, such as are used to remove liquid from a film strip in photographic processing apparatus, are mounted on respective shafts 24, 25 with their end faces 26, 27 offset with respect to each other. The shafts are supported in a journal plate 32. An end cap comprises a cup 31, slidable on shaft 25, bearing against a washer 28 which is a close sliding fit on roller 23. A spring 30, acting on cup 31, causes the washer to be pressed against the end face 26 of roller 22. A similar end cap arrangement is provided at the other end of the rollers. The purpose is to prevent liquid from creeping round the end faces of the rollers from the "dry" side to the "wet" side, and so wetting the edges of the film strip as it emerges from the "dry" side, as in Figs. (not shown) 1 and 2.

Abstract: 1459130 Boring earth &c W N SUTLIFF and J L DOWNEN 13 Nov 1974 [7 Feb 1974] 49072/74 Heading E1F A well jar tool which enables jarring blows to be delivered both upwardly and downwardly comprises a pair of telescopically-related tubular elements 26, 27, Fig. 2, defining an annular hydraulic-fluid chamber 117 therebetween. To apply an upward jarring blow from the starting position of Fig. 2, the outer tubular element 26 is tensioned by the drill string (30), Fig. 1 (not shown), and the outer element travels upwardly until a cylindrical surface 44 thereon arrives at an annular piston 92 on the inner element 27 whereupon fluid in the chamber on opposite sides of the piston communicates via a restricted adjustable passage 100 in the piston. Continued upward movement of the outer element causes a build up of the fluid pressure in the lower portion of the chamber 117 and of the tension in the drill string. When the cylindrical surface 44 passes out of engagement with the piston 92 the outer element surges upwardly and an impact surface (70), Fig. 4 (not shown), thereof strikes an anvil (115) on the inner element. To jar downwardly from the starting position shown, a downward force is applied to the string and the outer element moves downwardly until an inclined surface 43 on a ring 41 fixed to the outer element engages a similarly inclined face 89 on a resilient tripping device 86, Fig. 16. The downward force is increased until quadrants 87 of the tripping device yield inwardly permitting a sudden violent movement of the outer element downwardly resulting in the impact of surfaces (73 and 116) of the outer and inner elements, respectively. The impact surfaces (70), (73) of the outer element are provided on a splined female member (63), Fig. 19 (not shown) which is split longitudinally into two halves and is screwed into the lower end of the outer tubular element.

Filed: 1971-10-26
Abstract: 1362051 Matrix stores RCA CORPORATION 26 Oct 1971 [2 Feb 1971] 49639/71 Heading G4C Field effect transistors of the variable threshold type are arranged in rows and columns, each column having control electrodes connected to a common word line W and each row having a pair of bit lines B connected to the two other electrodes of each transistor in the row, and one of two voltages is selectively applied to each bit line, word line and the substrate(s) on which the transistors are formed. The transistors may be formed on a common substrate 51 having switching transistors S s1a , S s1b  or the substrates for the different columns may be isolated from each other by dielectric or diffusion regions and have individual switches. To clear a selected column, O is applied to its word line while -V is applied to all the bit lines, the remaining word lines and the substrate, this driving all transistors of the column to the low threshold voltage state. A selected transistor is driven to the high threshold voltage state by applying -V to its word line and O to its bit lines and to the substrate. Neither of these operations disturbs the non-selected transistors. A word is read out non-destructively by applying a voltage, greater than the low threshold level, to the selected word line, O to one bit line of each pair and, say, - 5v. to the other bit line of each pair.

Abstract: 1443213 Machinery safety devices BRANSON ULTRASONICS CORP 5 Nov 1973 [6 Nov 1972] 51286/73 Heading F2J A safety control system for controlling operation of an ultrasonic welding apparatus 12, or punch press (not shown) until such apparatus has entered a safe condition, comprises an electronic safety control circuit 10, the operation of which requires substantially simultaneous (i.e. within a predetermined time interval) twohanded actuation of a pair of laterally spaced apart palm push-buttons 28-28<SP>1</SP> which activate switches 26-26<SP>1</SP> in the control circuit 10 to produce two input signals that are passed to a coincidence and incidence network 32 which senses that the signals occur within the abovementioned predetermined time interval and produces a load enabling signal on line 34 which is passed through an OR gate 36 to close an output switch 38, the switch being coupled to a load 40, such as an electromagnetic coil of a relay, controlling the operation of a movable head 14 of the ultrasonic welding apparatus 12. The arrangement is such that with the welding apparatus 12 in an unsafe condition, i.e. with the movable clamping head 14 in the up, i.e. open position free of a workpiece 16 as shown in full in Fig. 1 and before it is fully closed, when operated, on the workpiece 16, release of either or both push-buttons 28-28<SP>1</SP> stops the clamping head 14 to avoid injury. A pressure sensitive switch, i.e. sensor 18, 20 responsive to the position of the movable head 14 provides a control signal on line 22 indicative of an unsafe condition when the head 14 is open and free of the workpiece, or a safe condition when the head 14 is closed, i.e. clamped on the workpiece. In this latter, i.e. safe condition the appropriate, i.e. safe signal from the switch 18, 20 acts via an interlock network 42 to isolate the enabling signal from the manual control push-button input switches 26-26<SP>1</SP> to effectively remove control of the safety circuit 10 from the manually operated input switches 26-26<SP>1</SP> while enabling the operation of the welding apparatus 12 to continue through an inhibitor network 44 and the OR gate 36 to maintain the output switch 38 closed. When the welding cycle of operation is completed, the head 14 is raised thereby terminating the safe condition signal from sensor 18 and resetting the safety circuit for the next cycle of operation, the inhibitor network 44 being rendered operative to prevent signals on line 22 from operating the output switch 38 during such time periods when the output switch 38 is open thereby preventing energizing of the relay 40 and welding apparatus 12 responsive to accidental actuation of the safe condition detecting sensor 18.
