Abstract: 1396981 Electric selective signalling; radio receiving apparatus M DESPREZ M-T PORTES and J-C GRUSELLE 2 May 1972 [3 May 1971] 20434/72 Heading G4H [Also in Division H3] In an arrangement whereby a videocassette 24, 26 may be switched into a T.V. receiver circuit in place of the T.V. audio and visual channels 1, 29 and vice versa, tuned circuits 6a, 6b ... 6n detect the components of a series or parallel frequency signal causing corresponding relay contacts 12a ... 12n to close and complete a circuit for the energization of a solenoidoperated switch 3, which realigns contacts 2, 2a, 21 and 27, 27a, 28. With a parallel frequency combination, contacts 12 are closed simultaneously; with a series combination, closure of the first relay contact 12 also energizes a timelag relay 32, Fig. 3 (not shown), which retains each contact in its closed position after closure thereof until the switchover has been effected. A timing device 14 ensures that the switchover only takes place at certain preselected times. The switch comprises a disc 37, Fig. 4, having contacts disposed around its periphery; energization of solenoid 3 attracts a helical screw 36 which engages the disc and rotates it through 90 degrees, a freewheel device preventing any contra-rotation when the screw is withdrawn. Relays 12 (and the triodes elsewhere) may be replaced by transistors (Fig. 2, not shown).

Title: Improvements in or relating to web supply apparatus
IPC: A24C5/20
Filed: 1963-05-22
Abstract: 1,039,106. Feeding webs. R. A. BUTLER. May 22, 1963 [May 22, 1962], No. 20450/63. Heading B6B. [Also in Division F2] Web supply apparatus comprises a base 10, and a pair of collapsible mandrels 12, 14 (see Division F2), one for supporting a roll of running web and the other for supporting the replacement web roll. The leading end of the replacement web is prepared for splicing with a length of pressure-sensitive adhesive 102, Fig. 2. A pair of freely rotatable nip rollers 16, 18 are provided to form the splice. An accelerator is provided at each mandrel to set the replacement web roll in motion by a single side at the time that the splice is made to the running web. The accelerator comprises an arm 72 (88), a spring 76 (92) urging the arm in the web supply direction; a one-way clutch 70 (86) coupling the arm to the mandrel, and a latch 74 (90) engaging the arm and releasable to cause the force of the spring to be applied through the arm and the clutch for accelerating the replacement web roll. A detector for each web-roll which sets the splicing operation in motion when the diameter of the running webroll is near exhaustion comprises a lever 240 (256), Fig. 1, which operates a normally open switch 252 (268) with a flexible finger 248 (262). The switch energises a solenoid 20 (22). A thumb-screw 250 (266) which is engaged by the flexible finger, prevents the lever from resting heavily on the surface of the running web-roll, the first few layers of which nearest the core may be distorted. The switch is operated when the finger 248 escapes from the screw, due to the weight of the lever when finally not supported by the running web roll. In operation, when the solenoid 20 is energized, the latch 90 which is connected to the armature 170 of the solenoid by a cable 270 is released. The mandrel 14 is therefore given a kick start to accelerate the replacement web roll. Movement of the armature 170 also causes a lever 144, Fig. 2, through a cable 174 and a spring 178 to raise the leading end of the pressure-sensitive tape 102 into the nip between rollers 16 and 18. The leading end of the replacement web was previously attached by suction to a member 134 fixed to a vertical slide 136 which co-operates with two levers 144 and 146. At the same time the armature 170 causes a blade 182 to pivot into engagement with the underside of the exhausting running web 26 to press it against a stationary blade 190 thus severing it. When the web roll 28 on mandrel 14 is near exhaustion, the armature 22 releases the latch 74 and operates the lever 142 and the pivoted cutter blade 184 in the same manner. Spring-pressed rollers 216 and 220 mounted on a movable block 228 guided on parallel rods 232 take up any sudden changes of tension in the running web. The web is also guided laterally before passing between rollers 16 and 18 by a pair of fingers 196 (208) depending either side of the web from the fixed knife blade 190 (202).

Abstract: 1352251 Transistor amplifiers INDUSTRIAL NUCLEONICS CORP 19 April 1971 [11 March 1970] 20822/71 Heading H3T [Also in Division G1] A radiation measurement system comprises a radiation detector provided with an electrometer circuit, for amplifying the low level D.C. signal from the detector, the circuit including at least one metal oxide semi-conductor element which is prevented from breakdown or puncture by voltage transients by filtering and limiting circuits. As shown a gauge, for measuring thickness, density, basis weight (mass per unit area) (e.g. in paper making) or other absorption dependent property of a sheet 2, is comprised of a beta particle source of, e.g. strontium 90 or carbon 14 and an ionization chamber 6. The metal oxide semi-conductor circuit comprises a dual MOSFET circuit 34 arranged with an operational amplifier 40 to provide the difference between the input signal at 36 and a reference signal at 38. The high megohm resistor 42 (of lower impedance than the input impedance of device 34) maintains the input at 36 near to zero potential. The limiting device 48 limits input voltages to below the rated value for the MOSFET element and preferably provides a range of allowed levels between upper and lower reference voltages. Since voltage spikes having high rise times and high frequency components may be passed by 48, a low pass filter 50 is also provided to cut out these transients. A further limiter 54 is provided to prevent feedback transients. Also over voltage protection is provided for the amplifiers. The circuit is zeroed under the control of control logic 18, line 24 being provided to cause via 28, the opening of switch 30a and closing of switch 306.

Abstract: 991,424. Stamping. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 11, 1963 [May 30, 1962], No. 20926/62. Drawings to Specification. Heading B3Q. [Also in Division G6] As a step in the manufacture of a nuclear reactor fuel element, the protective sheath of the element is deformed into intimate contact with the fuel member by external pressurization brought about by a high-energy shock-wave or waves. The shock-wave or waves may be generated by a rod of explosive placed parallel with the assembled fuel element in a water-filled vessel and fired electrically. Alternatively electromagnetic means may be used, the element together with a copper tube in which it is coaxially disposed being positioned within a coil through which a bank of high capacity condensers is repeatedly discharged, thus setting up an intense variable magnetic field. A current is thereby induced in the tube which generates a magnetic field opposed to that set up by the condenser discharges and thereby subjects the tube to a physical force, which force effects deformation of both the tube and the protective sheath of the element. A similar device uses a spark-gap in place of the coil, a tungsten or titanium wire being connected across the gap which is immersed in a cylinder of water close to the element. On discharging the bank of condensers the wire vaporizes to create a high-energy wave front. In the embodiments described, the fuel element comprises a stack of pellets of ceramic fissile material enclosed withing a stainless steel sheath, one or more non- fissile pellets which divide up the stack of fissile pellets being each formed with a circumferential groove into which the sheath is deformed in order to provide a degree of keying. Specification 958,697, and U.S.A. Specification 2,976,907 are referred to.
