Patent GB-977357-A (GB)
Title: Pulse-current generator
IPC: H03K3/53
Filed: 1962-07-27
Abstract: 977,357. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. July 27, 1962 [July 27, 1961], No. 28978/62. Heading H3B. The leading edge of a rectangular pulse supplying an inductive load L is controlled by and the final amplitude determined by means of a winding N1 on a core  of square loop material biased far into saturation by a current in a bias winding N2. The capacitor C1 is charged to voltage U1 which is greater than voltage U2 through a current limiting resistor Rv before switch S1, which may be electronic, is closed. On closing switch S1 a current flows through the load L and winding N1 in a direction such as to bring the core U out of saturation. Until the core  reaches the bend of the hysteresis curve the winding N1 has little impedance and the current increases rapidly, but on reaching the bend winding N1 has a high impedance and tends to limit the current to the value then obtaining. The value of capacitor C1 is so arranged that the voltage across it is slightly less than voltage U2 so that diode D conducts thus maintaining the current. The resistor Rv may be replaced by an electronic switch (Fig. 2, not shown) which must be opened before switch S1 is closed. Fig. 3 (not shown) illustrates how decoupling diodes may be inserted to operate several such circuits from the same voltage sources.

Abstract: 362,568. Friction clutches ; operating clutches. BRADFORD, G. H., BRADFORD, R., BRADFORD, R. P., and BRADFORD, W., 752, High Road, Tottenham, London. Sept. 29, 1930, No. 29038. [Class 80 (ii).] A friction clutch is disposed in the interior of one of a pair of geared wheels contained in a casing on one face of which are fixed inclines which impart a longitudinal movement to a rotary cam member to bring a frictional pressure to bear on the clutch plates. Plates 24 engaging the square hollow within a worm wheel 25, alternate with plates 26 mounted on the square end of a sleeve 14. A cam 27 having inclines 4 engaging fixed inclines 3 on the casing 2 is adapted to apply pressure to the plates when rotated by a rod 10 having a lug engaging a recess in a projection 7 of the cam. The rod 10 may be connected to a control liner which may be moved beyond its dead centre position to remain in engaged position. For this purpose the rod may be broken and connected together by means of a sleeve housing a piston with a spring on one part while a cap on the sleeve is connected to the other part. The driven shaft 11 is connected by a dog clutch 12 to the sleeve 14. Rotation of the worm is transmitted by worm wheel 25, the clutch 24, 26 and the dog clutch 12 to the shaft 11. The worm wheel 25 is bolted to a flange 17 on a sleeve 13. The sleeves 13, 14 have a spigot connection 19 and carry the two halves of the casing. The sleeve 14 is provided with a thrust collar 15. Thrust bearings 16, 18 are provided between the cam 27 and the clutch plates and between the flange 17 and this casing 2. Rotation of worm wheel is in such direction as to tend to keep inclines 3, 4 engaged. The clutch may be applied to a central shaft, e.g. the axle of a cultivator and the shaft varied in length by varying the setting of the dog clutch 12 thereon.

Patent GB-1534030-A (GB)
Title: Logical interrupt circuit
IPC: G06F13/26
Filed: 1976-07-13
Abstract: 1534030 Priority circuit INTERNATIONAL STANDARD ELECTRIC CORP 13 July 1976 [22 July 1975] 29111/76 Heading G4A An interrupt-signal priority and masking circuit accepts and stores interrupt signals independently of associated masking bits when associated mode bits are reset, and, when the associated mode bits are set, only if the associated masking bits indicate that the signals are unmasked stored interrupt signals being forwarded for priority resolution. The mode bits allow masked interrupt signals to be accepted but not processed until the masking is removed. Masking-bit BO2-B32 and mode-bit B03- B33 stores, corresponding to interrupt signals IN0-IN3, are initially set (binary 1, unmasked) and reset (binary 0) by signal RZ when power is turned on. The stored bits can subsequently be modified by signals on inputs D0-D3, the masking-bit stores being clocked at EN2 and the mode-bit stores at EN3. The masking-bit stores B02-B32 can also be reset (binary 0, masked) individually by signals on inputs MHO-MH3 or in common by a signal on input I ac. With a mode-bit store B03-B33 reset the corresponding interrupt signal IN0-IN3 is stored in the corresponding flip-flop B00-B30 and clocked, EN1, into the corresponding flip-flop B01-B31 independently of the state of the corresponding masking-bit store B02-B32. However the stored interrupt signals are blocked, by NAND gate 5, unless and until the corresponding masking-bit store is set (unmasked). With a mode-bit store B03-B32 set the corresponding interrupt signal IN0-IN3 is stored and clocked into the corresponding flip-flop B01-B31 only if the corresponding masking store is set (unmasked). Unmasked stored interrupt signals are forwarded by NAND gates 5 to NAND 8 whose output I indicates whether any unmasked stored interrupt signals exist. A priority circuit 10 selects and coder 11 generates a code A1, A0 representing the highest priority unmasked interrupt signal whose flip-flop B00-B30 is reset via gates P0-P3 unless the inhibit signal EN4 is active. The circuit may be formed as an integrated circuit and may be coupled to an exactly similar circuit to handle twice the number of interrupt signals. In this case the output I of the higher priority one of the two circuits provides the inhibit signal EN4 for the lower priority circuit. The outputs A1, A0 from the two circuits are connected together and a further identifying bit A2 is provided by one of the I outputs.

Abstract: 1,208,028. Washing hollow-ware. G. CONTE. 19 June, 1968 [28 June, 1967], No. 29184/68. Heading B8T. An apparatus for cleaning scientific glassware with recirculated de-ionized water checked for conductivity comprises a plastics housing provided with a horizontal partition 2 sloping towards a central drain 3 opening into a tank 4 having a transverse wall 5 supporting a cell 7 for measuring the conductivity of the water. A pipe dipping into a central well 10 provided in the tank leads to a pump 11 for forcing water through one or more ion-exchange columns 13 to pipes 17 and 18, pipe 17 leading to a test tube washer 21 and pipe 18 to discharge outlets 18a and a pipette washer 20. Valves 15, 22 control the flow to the various washers. Pump 11 and columns 13, which columns may be interchangeable, are supported in a lower housing 12 to which the upper housing is pivoted at 19. An upper partition 24, 25 can support larger articles of glassware. The pipe 3b leading to the conductivity cell is arranged to extend about 1 cm. above the drain so that only water from one of the discharge outlets 30, 31 or from a funnel 27 and tube 28 passes through the cell, and not water draining through the drain. Thus, water from any of the washing devices can be checked by moving appropriate device outlet over the tube 3b. Specific resistances in the region of 5-6 Megohms can easily be obtained, even though the apparatus is open to the atmosphere.

Abstract: 800,571. Winding lace machine bobbins. PRICE, R. A., PRICE, J. H., PRICE, W. H., and PRICE, R. R. April 25, 1956 [Feb. 14, 1955], No. 29571/54. Class 74 (1). [Also in Group IX] Lace machine bobbins are wound in a machine that has means for masking the periphery of one of the side plates and guiding threads between the plates to facilitate threading up. A slide 60 feeds bobbins individually from a stack 59 to the slotted end of a tray 86 from which they are removed by guide members 4, 5 carried by a bifurcated arm 90 mounted for rotation around a spindle 80. Before receiving a bobbin, guide member 5 is in its lowest position but is raised by a cam rise 73 against which a spherical stud 7 acts so that a stud in the guide member 5 engages the hole in the bobbin. As the stud 7 engages a rise 71, guide members close together and the bobbin is securely engaged in a dished part of a guide member 4 so that the upper side plate of the bobbin is shrouded. As the arm 90 continues to rotate, thread extending from a bobbin carried on another arm is guided by the member 4 between the plates of the empty bobbin. The thread is then cut and winding starts on the fresh bobbin. Continuous rotation of the arm 90 brings wound bobbins to a fork 33 that directs them down a shoot 36 to a storage cylinder 37. The amount of thread wound on a bobbin is dependent on the relative rate of rotation of a chain wheel 1, driving the bobbins through sprockets 2 and members 4, and the arms 90. Tension on the thread is graudally reduced during winding and as the tension is reduced the bight of thread passing to the bobbin is increased in length by movement of an arm 48 so that, at the instant of cutting, a length of slack thread is provided which assists in wrapping the thread round the empty bobbin. A stop motion is operated on breakage of the thread or if a bobbin should jam between the members 4, 5. According to the Provisional Specification, the guide member that shrouds a bobbin plate may be non- rotatable and only mask a portion of the plate's periphery or it may be a disc having a bobbin receiving recess in each face. A multiplicity of such discs may be mounted on a mandrel carrying several bobbins to be simultaneously wound. A machine is described in which such bobbin assemblies are releasably mounted on a conveyer and carried in turn to a winding station.
