Title: Improvements in or relating to Cathode Ray Storage Tubes
Inventor: TRODDEN WILLIAM GEORGE
IPC: H01J31/12
Filed: 1967-08-07
Abstract: 1,168,524. Luminescent materials. M-O VALVE CO. Ltd. 31 July, 1968 [7 Aug., 1967], No. 36085/67. Heading C4S. [Also in Division H1] A target for a cathode-ray storage tube comprises a glass screen 12, Fig. 2, a conductive layer 13 of tin oxide, a layer 15 of D.C. luminescent material which is preferably a PN- junction but may be an electroluminescent phosphor, a semi-conductor layer 16 adapted to act as a double-injection device, and a conductive layer 17 of gold adapted to act as a hole-injecting layer. The double-injection device has two stable values of current for a given voltage within a certain range (Fig. 3, not shown), and is biased by a battery 14 to a value within this range. Normally the device operates at the lower of the two current ranges, but when and where the layer 16 is bombarded by a writing electron beam the current switches to the higher range, resulting in an increased potential across the layer 15 which causes it to emit light. The resulting image is sustained by the supply 14 but may be erased by closing switch 18 to remove the supply; this also causes any charge left on layer 17 to dissipate. The light produced is preferably at the red end of the visible spectrum to reduce the possibility of the light affecting the operation of the double-injection layer; if desired, back-radiation may be prevented by a layer of radiationabsorbing material between layers 15 and 16. The layer 15 may be of gallium phosphide 10 microns thick doped to be N-type in the region 20 by the diffusion into it of tellurium and oxygen, and doped to be P-type in the region 19 by zinc impurity; the junction 21 should be nearer the beam side of the screen. The layer 16 may be of cadmium sulphide, zinc sulphide, gallium arsenide or gallium phosphide and may be 10-100 microns thick. The gold layer 17 may be 1000 Š or less in thickness and the tin oxide layer 13 from 100-1000 Š thick.

Title: Electrical capacitors
IPC: H01G9/12
Filed: 1974-08-21
Abstract: 1481978 Capacitors ROBERT BOSCH GmbH 21 Aug 1974 [22 Aug 1973] 36678/74 Heading H1M Casing 13 of self-healing capacitor 10 has corrugations 18, 20 to permit relative movement between two parts of the easing on increase of pressure within the casing which movement is harnessed to rupture wire 25 and disconnect the capacitor, corrugations 18, 20 being of different depths and/or rigidity. When gas is generated as a result of electrical overload, after an initial lag indicated by zone I in the expansion/pressure diagram shown in Fig. 3, there is a comparatively rapid expansion (zone II) as the less rigid or deeper corrugation extends and it is in this region that the wire is arranged to rupture (point A) for early cut-out. Particularly in the case of dielectrics comprising synthetic plastics, rapid gas generation may continue after cut-out, and this is controlled and contained by the less rapid expansion (zone III) as the more rigid corrugation extends. The initial play of non-rupturing lead 27 may be such that it becomes tight during the expansion and co-operates to retard the expansion in zone III. As shown a pasteboard plate 15 is located between the capacitor roll and upper insulating cap 17. In an alternative embodiment (Fig. 7, not shown) a metal plate is used which may provide a cutting edge bearing on the rupturable wire. A deep corrugation may be provided between two shallow corrugations, the latter holding in position the capacitor roll and the casing cover as the central corrugation extends. The empty space may be filled with incombustible material such as sand occupying up to 50% of the space (Fig. 8, not shown).

Title: Improvements in or relating to dispensing apparatus for fluids
IPC: G06M1/32
Filed: 1962-09-27
Abstract: 940,525. Liquid dispensing apparatus. AVERY-HARDOLL Ltd. Sept. 27, 1962 [March 8, 1962], No. 36751/62. Heading A4T. In apparatus for delivering measured quantities of fluids including a fluid meter and indicating drums 3-6 mounted freely on a shaft 1 to which rotational movement is imparted by a zeroizing device for the drums, the engagement and disengagement of carry-over planet wheels 13, 14, 15 with driving and driven elements-on the drums, the engagement and disengagement of gearing connecting the lowest order drum to the meter and the position of zeroizing levers 24b acting to return the drums to zero position, are all controlled by cams 8-11 fast with the said shaft. Each of drums 3, 4, 5 is fast with a disc 3a, 4a, 5a provided with a dog 3b, 4b, 5b and drums 4, 5, 6 are each fast with a toothed wheel 4c, 5c, 6c. The discs 3a, 4a, 5a and toothed wheels 4c, 5c, 6c co-operate with planet wheels 13, 14, 15 to form carry over devices. Drum 3 is driven through a toothed wheel 3d fast to it and a gear 7 movable into and out of mesh, by a toothed wheel 28 connected to the fluid meter device. Each of drums 3-6 is fast with a cam 3e-6e and fixed on shaft 1 are cams 8-11, cam 8 co-operating with a follower wheel 29a carried by a bell-crank lever 29 carrying wheel 7 and a spring 22 tends to apply wheel 29a against cam 8 and if the latter permits it make wheel 7 mesh with wheel 3d. Cam 10 co-operates with a follower wheel 23a carried by an arm 23 on shaft 24 carrying zeroizing levers 24b which co-operate with the heart shaped cams 3e-6e. Fixed on shaft 1 are the rotor of a zeroizing motor 31 and a cam 32 co-operating with a follower wheel 33. The nozzle is hooked on a switch 42. A change over switch 39 is controlled by a coil 40 and a change over switch 46 is controlled by wheel 33. During delivery the zeroizing motor 31 is stopped as shown in Fig. 5 and shaft 1 is then stationary, clutch wheel 7 transmits rotational movement of wheel 28 to wheel 3d and thus drum 3. When the user stops delivery drums 3-6 stop and indicate the quantity delivered but when the nozzle is returned to hook 43, switch 42 is displaced and the pump motor stops. Motor 31 is supplied with current and rotates shaft 1 and cam 32 but stops after rotation of 45 degrees when wheel 33 has descended. To make a new delivery the nozzle is unhooked and motor 31 is again supplied with current but since coil 40 is not supplied with current the delivery pump remains stationary. Wheel 7 becomes disengaged by cam 8 and the planet wheels are disengaged. As shaft 1 continues to rotate the levers 24b approach the cams 3e-6e and return them to the zero position.

Title: Improvements in or relating to Detonator Devices
Inventor: MOORE LAWRENCE KING
IPC: E21B43/1185
Filed: 1966-08-17
Abstract: 1,161,907. Tube expanders; perforating; dividing by a single blade. L. K. MOORE. 17 Aug., 1966, No. 36778/66. Headings B3J and B3W. [Also in Divisions F3 and H1] The detonator 65 and primercord charge in section J of a well pipe are exploded by pulling on a slick wire W of a detonator apparatus so as to move upward a pipe 35 carrying an electrical container 44 which eventually engages a stationary contact 38 in circuit with a battery (12), Fig. 2A (not shown), carried in the section 2A. The contacts are carried in members 39, 42 which are fast respectively with a stationary sleeve 40 and with the pipe 35 and enclosing an oil chamber 43. To suitably delay the action, the oil escapes, through a restriction (50a), Fig. 7 (not shown), in a check valve 50, into a flexible bellows 55. The detonator and charge are located in section 2 by a spring catch 70. Relative movement between parts of the apparatus is allowed for by a pin and slot connection 35c, 41. In the event of malpositioning of the charge, movement imparted through a jarring device " X," will move a tube 26 in a safety section 2B to sever a shear pin (29), Fig. 2B (not shown), and allow movement of the tube 26 relative to a severing member (32) to sever the electrical lead 25. In the form shown, the charge is carried by an extension 60 of the stationary sleeve 40 and is located by spring latching fingers 70 within a thicker-walled collar J if a joint which is to be released, so that damage to the thinner-walled well pipe T is reduced. In another embodiment, a conventional perforating charge (P, Fig. 6, not shown) is suspended by a cable from an extension (42, 57) of the movable pipe (35).

Title: Stabilization of monomers
IPC: C07C17/42
Filed: 1956-12-04
Abstract: Polymerizable ethylenically unsaturated monomers, for example chloroprene, styrene and butadiene, are stabilized against granular polymer formation by contact with an amount of the nitrite form of an insoluble, strongly basic, N-containing anion exchange resin sufficient to provide at least 0.001 per cent of the nitrite ion, based on the weight of the monomer.  Examples show that the self-propagating polymerization reaction, initiated by seeding either liquid chloroprene or sytrene or chloroprene vapour in contact with liquid chloroprene with a small quantity of activated chloroprene granular polymer, is inhibited by the presence of the nitrite resin in contact with the liquid monomer.

Title: Monostable or astable multivibrator
IPC: H03K3/284
Filed: 1964-09-11
Abstract: 1,079,927. Multivibrators. SCHALTBAU G.m.b.H. Sept. 11, 1964 [Sept. 11, 1963], No. 37287/64. Heading H3T. An astable or monostable multivibrator using semi-conductors, thermionic valves or coldcathode tubes has an inductance in the collector or anode lead of one or both of the switching elements, such inductance being shunted by a coupling capacitor and a discharge resistor, the latter being itself shunted by a diode. Fig. 1 shows a monostable circuit in which the switching time is regulated by a variable inductance L, the stored energy in L being transferred to the coupling capacitor C 1  when the input signal at C 2  ceases, thus prolonging the switching time. The diode D 1  shorts the resistor R 1  during discharge. A variable resistor or opposing voltage can be included in series with the inductance; this can be the emitter-collector path of another transistor. The resistor R 1  can also be variable. Fig. 2 (not shown) describes an astable multivibrator with two coupling capacitors and a variable inductance in each collector lead. The invention is particularly useful for controlling the driving motors of trackless battery vehicles, cranes and other conveyer equipment, since the switching time can be controlled without the high wear due to mechanical adjusting means which pass current.

Patent GB-374048-A (GB)
Abstract: 374,048. Measuring short-time intervals. IHDE, H. A., 26, Drottninggatan, Orebro, Sweden. Feb. 19, 1931, No. 5314. Convention date, Feb. 20, 1930. [Class 139.] Apparatus for measuring short-time intervals, such as the time taken by a person to respond to a stimulus or for a car to pass between two spaced electric contacts in a road, comprises a tube 6 pivoted at 2 to a baseboard 1 and adjustably supported in an inclined position by slotted struts engaging its free end. The tube is slotted at 18 on its upper side and contains a ball 5 which may be released from a stop 26 at any arbitrary moment and stopped at any later moment by one of a number of fingers 10 .. 16 mounted on a spring- urned spindle 7 and allowed to swing into the slot 18 on release of the spindle. The fingers are normally held free of the slot by a spring pawl 24 engaging a notched disc 22 on the spindle. The position of the ball in the tube when stopped by lifting the pawl 24 indicates the time taken to respond to the stimulus. The fingers 10 .. 16 may be so spaced as to indicate equal time intervals, for example 0À05 sec. In a modification the fingers may carry a rubber or like covered graduated rod, adapted to bear on and stop the ball. A further modification comprises two concentric slotted tubes the inner of which is rotated by a spring on being released, thus allowing the ball to drop into one of a number of compartments beneath the tubes. In another modification, having fingers as above, the tube is of helical form. In other constructions (1) a pulley is rotated, when released, by unequal weights connected by a cord passing over the pulley, and is stopped by a brake lever ; the time of motion is indicated by a pointer geared to the pulley and rotating over a scale ; (2) the weights in (1) are attached to the arms of a lever to which the pointer is geared or directly connected ; (3) a heavy nut is caused to descend by rotation on one or more frictionless screw threads, and to be stopped by a brake, an annular projection on the nut indicating the time of motion on a scale ; alternatively the screw may be made to move relative to the nut. The release and braking of the movable body may in all cases be effected electromagnetically.
