Title: Improvements in or relating to bi-stable trigger circuits
IPC: H03K23/76
Filed: 1959-08-27
Abstract: 898,741. Circuits employing bi-stable magnetic cores. SIEMENS & HALSKE A.G. Aug. 27, 1959 [Aug. 27, 1958], No. 29347/59. Class 40 (9). A bi-stable state trigger circuit suitable for use in a binary counter comprises cores I and II each having input windings for receiving input pulses, and an output winding, means for biasing core II so that it always assumes one state in the absence of signal pulses, and means operable when both cores are in a predetermined state to switch core I to its other state. The circuit shown is initially such that cores I and II are in the +ve and -ve remanant states respectively. The onset of the first input pulse, applied at E, changes over the cores to the -ve and +ve states respectively. The output voltages from windings SI and SII are of opposite polarity and cancel out. When the first pulse ceases the bias winding V causes core II to revert to the -ve state. When the second pulse starts core II is changed over to the +ve state. The unopposed voltage from SII now causes transistor Tr to conduct and the output current changes core I to the +ve state. When the second pulse ceases core II is returned to the -ve state by its bias winding V. The transistor thus applies one output pulse to the load Ra for every two input pulses. A plurality of these circuits may be connected in cascade to form a multi-stage binary counter.

Abstract: 432,539. Piston extrusion-apparatus BILLING, N. P., 11, Pembroke Square, South Kensington, London. Oct. 23, 1933, No. 29362. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 26, 1934]. [Class 102 (ii)] [See also Groups XV, XVII, and XVIII] A dispensing device for extrudible materials comprises a valve which controls the outlet from a tube &c. containing the material and a pocket into which it is extruded for use. Fig. 2 shows a section of the form in which the tube is made of material known under the Registered Trade Mark "Bakelite." The tube is closed by a screw cap 21 at the lower end and by a rotary valve element 24 at the top which co-operates with a fixed seat 25. A tube 26 is secured to the element 24 and has an external thread 28 which operates a piston 29. A discharge aperture 30 at the top of the tube 26 communicates alternately with two pockets 34 and each pocket is covered by a baffle 22 until it is moved into register with an opening 23. The tube is filled by a replaceable cartridge 35 and on turning the element 24, material is forced up the tube 26 by the piston 29 into the pockets, whereupon it is removed by a finger, toothbrush, &c. A spring may be employed in conjunction with the piston 29 instead of the screw device. When applied to a collapsable tube a fixed tubular valve element 43, Fig. 6, is screwed to the usual tube neck and cooperates with a rotary element 46. Passages 45, 49 in the two elements are brought into and out of register on rotating the valve and the pocket 50 is covered during the filling operation by a skirt 48 on the rotary element. In another form a rotary plug valve has a pocket on one side which is turned into communication with the tube and then with a delivery orifice on the outer side of a hollow holder. In a modification of the form shown in Fig. 2, a non-return valve is fitted at the outer end of the stem 26 and a measuring cup is added to receive the extruded material. In a still further modification the rotary valve element is in spider form and four pockets therein successively register with a slit which leads to a dispensing pocket in the fixed element.

Abstract: 419,236. Switching systems for lamps; valve amplifying circuits. VASILACHE, S., 14, Boulevard St. Jacques, Paris. Oct. 24, 1933, No. 29425. Convention date, Oct. 24, 1932. [Class 38 (iv).] In a lighting system on a road vehicle, light from an approaching vehicle activates a light sensitive cell 2 arranged to control a thermionic valve 4 which is energized with A.C. through the secondary 6 of a transformer 18 the primary of which is supplied with interrupted D.C., the valve 4 controlling the energization of a relay 9 which causes change-over of the supply from the head lamps 29 to the dim lamps 32 through contacts 27, 28 of an intermediate relay 23. A change-over switch 35 permits voluntary energization of the head lamps and a switch 36 permits continuous operation of the dim lamps. A source 31 of non-dazzling rays may be energized with the dim lamps to activate a corresponding system on an approaching vehicle. The circuits of the thermionic valve 4 are controlled by a switch 37, and the valve filament may be supplied with D.C. or low tension A.C. from the transformer 18, whilst the interrupter 19 may be operated from the engine or may be the usual coil ignition interruptor. The cell 2 is connected in series with a variable resistance 3 across the secondary 6 of the transformer 18 and the grid of the triode 4 is connected to the junction of the cell and resistance. The cathode of the valve is connected through a potentiometer 12 to a tapping 11 on the secondary 6 and the anode through the electromagnet 9 to the end of the secondary 6 connected to the cell 2. The system forms a bridge connection in which the grid of the triode is normally negative when the anode is positive with respect to the cathode. In a modification the coil of the intermediate relay 23 is connected in series with an induction disc on which the flux of the electromagnet acts so as to rotate the disc against a spring and operate a cam contact to maintain the headlamp connection around contacts 27, 28 for a short time and then open it so as to ensure activation of similar apparatus on an approaching vehicle.

Abstract: 1276592 Fastener setting tool ATLAS COPCO AB 19 June 1970 [27 June 1969] 29760/70 Heading B3N A threaded fastener setting tool with torque release means comprises an electric or as shown a pneumatic motor 11 and driving and driven clutch part 19 and 28, the driven clutch part 28 being positionable either in driving engagement with clutch part 19, in a disengaged position as shown in Fig. 1 or in a release position as shown in Fig. 6, caused by a separating spring 32, where the motor 11 continues to rotate. Clutch part 28 is hexagonal and slidingly seats in a socket 27 of a clutch housing 26 which is connected to the tool spindle. Drive between housing 26 and clutch part 28 is by balls 38 whose position is controlled by a sleeve 37. The sleeve is biased by a spring 40 whose tension is adjustable. An elongate member 45 is radially disposed in housing 26 and engages a cam surface 48 of the sleeve 37. A pointed portion 44 of clutch part 28 engages member 45. In operation vertical movement of tool spindle 25 causes valve 13 to open via a stem 51 and a central spindle 31 of the clutch part 28. Also the clutch parts engage and drive is transmitted to the tool spindle when the loading becomes sufficiently high to overcome the tension in spring 40, the balls 38 force sleeve 37 downwardly which in turn forces member 45 inwardly so that a recess 49 is aligned with portion 44. Separating spring 44 forces clutch part 28 downwardly against spring 35. Valve 13 moves towards a seated position but does not close. When the tool is removed from the fastener, spring 32 further expands allowing zero setting, spring 35 returns clutch part 28 to the position shown in Fig. 1. The tool could be designed so that when portion 44 moves into recess 49, valve 13 closes the air supply. In another embodiment, Fig. 7 (not shown), the torque release means is associated with the driving clutch part instead of with the driven part.

Abstract: 1518984 Semiconductor devices NIPPON ELECTRIC CO Ltd 16 July 1975 [16 July 1974 13 June 1975] 29886/75 Heading H1K [Also in Division H3] Destruction of the gate insulation of an IGFET due to an excess drain or source voltage causing avalanche breakdown of the drain or source junction with consequential injection of hot carriers into the gate insulation, resulting in thermal destruction, is prevented by the provision of a so-called "gate-controlled rectifier" having a lower breakdown voltage than the drain or source junction of the IGFET. A "gate-controlled rectifier" effectively consists of an IGFET without a source region, and the relatively low breakdown voltage of its drain junction is obtained by selection of the doping level of the region or the substrate, by making the gate insulation of the gate-controlled diode thinner than that of the IGFET or by making the gate voltage on the diode more negative than that on the IGFET for an n-channel IGFET or more positive for a p-channel IGFET. In Fig. 5(B) the IGFET T 1  has a grounded source 7, a polysilicon gate 5 connected to a signal input terminal and a drain 6 connected via metallization not shown to an output terminal. Protection against excess voltage on the output terminal is afforded by selection of the gate voltage on gate-controlled diode D1 including region 10, which forms an extension of the IGFET drain region 6, and polysilicon gate 9 connected via metallization 4 to the substrate 8. A further extension of the region 6 extends to the output terminal. In Fig. 7 the diode region 104 is connected to the IGFET drain 103 via metallization 112 and is provided in a highly doped zone 105 of the substrate conductivity type which also serves a channel-stopper function.
