Title: Apparatus and method for the detection and measurement of radioactivity in the human body
IPC: G01T1/29
Filed: 1971-10-29
Abstract: 1389672 Measuring radio-activity UNIVERSITE DE SHERBROOKE 30 Oct 1972 [29 Oct 1971] 50361/71 Heading G1A The distribution of radio-activity of a tracer introduced into a volume e.g. of a patient for the location of a cerebral tumour, is determined by the use of a plurality of gamma-ray detectors viewing particular sections within the volume being examined and rotating either the detectors in synchronism around the patient or the object in front of the detectors. The detectors are designed to form "channels" of detection. In the simplest case, Fig.1, one channel is provided by detectors 14, 12 passing through the geometrical centre about which they rotate. The other channel is formed by detector 12 with detector 10 and is slightly offset from the centre. By taking the difference between the counts for the two channels, a measurement which is more accurate than would be obtained using a single detector, is obtained. In a more complex arrangement, Fig.2, a first channel is formed by detectors 16 with 22 and 18 with 20, and a second channel by detectors 16 with 18 and 20 with 22. The detectors are connected to coincidence circuits and a difference circuit as in Fig.3. Further accuracy may be obtained by the use of extra detectors for correction purposes Fig.7 (not shown). The detectors may be lead-containing plastics phosphors for use in scintillation detectors. The radio-active tracer may be a position emitter e.g. Am 74 which produces 7-radiation on interaction with tissue.

Abstract: 1,108,646. Spindle brake. PALITEX PROJECT-CO. G.m.b.H. 29 Nov., 1965 14 Dec.. 1964], No. 50551/65. Heading DID. In a spinning or twisting m/c movement of a thread guide 15 (e.g. by being pivoted sideways to provide access to the spindle for doffing) causes the spindle to be braked and movement of the guide 15 to its normal position causes the brake to be released. In addition movement of the guide may cause drive to the take up spool 26 to be interrupted. As shown lateral movement of guide 15 operates a pneumatic or hydraulic valve 44 to actuate a piston-cylinder arrangement 33, 34 to lift spool 26 out of contact with the driving drum: a further piston-cylinder arraneement pivots the whole twisting spindle to lift wharve 7 out of contact with its driving belt; a brake may also be applied to the spindle. In Fig. 1 not shown movement of thread guide 15 brakes the spindle via a mechanical linkage. In Fig. 6 not shown, guide 15 may be lifted to close electrical contacts to activate a brake operating circuit. In a further form a Bowden cable links guide 15 and the spindle brake.

Abstract: 1,028,850. Automatic control of current or voltage. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 29,1963 [Dec. 30, 1963], No. 51149/63. Heading G3R. [Also in Division H2] The control pulses for a device such as a thyratron or a thyristor supplying a regulated output current or voltage are derived from a circuit including a peaking transformer having its primary winding connected to a full-wave rectifier and its secondary winding connected to a clamping circuit which converts the output from the transformer into a square waveform; the leading edge of the square waveform is differentiated to provide the control pulses, the phase of which is varied in  dependence upon output variations by the action of a control amplifier connected in a feedback loop system. The input to the control amplifier is derived from a resistor monitoring output voltage or current, and the output from the amplifier is applied to a tertiary winding on the peaking transformer, which winding controls the width of the square wave and thus the phase of the control pulses. A second feedback loop may be connected in parallel with the control amplifier to improve the stability of the system.

Abstract: 1,193,020. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 Nov., 1968 [8 Nov., 1967], No. 52407/68. Heading H4F. In an arrangement for deriving the colour sub-carrier from the burst signal in a colour television receiver, the burst signal is applied to a passive integrator circuit 71 to regenerate the sub-carrier which is passed to an amplifier 81, the gain of which is controlled by the amplitude of the sub-carrier from a high pass filter 105, 107. The input and output phases of the combination of units 71 and 81 are compared in a phase detector 75 which provides an error signal at an input of integrator 71. The amplitude of the regenerated sub-carrier at terminal 83 is detected by 92, 93 and 95 and passed to the high-pass filter specified above and also to a low-pass filter 99 and 101 to provide an average amplitude thereof which controls the gain of an amplifier 17 in the chrominance signal path. The burst signal is separated from the chrominance signal in a burst separator 23. The gaincontrolled sub-carrier at terminal 83 is fed to the chrominance demodulator and matrix circuit 49 from whence the colour difference signals are applied to the picture reproducer 13.

Title: Apparatus for moving a member of controlled speeds
IPC: F15B13/04
Filed: 1971-11-11
Abstract: 1362592 Fluid actuators J D McLELLAND 2 Nov 1972 [11 Nov 1971] 52514/71 Heading F1D A actuator for moving a member, e.g. a tool slide, at controlled speeds comprises a double-acting fluid controlled piston 11, Fig. 1, attached to a tubular rod 26 carrying a tool holder 28 and a piston 29 within the rod 26 which is attached to a tube 32 and has a further tube 33 passing coaxially through it. Valve blocks 20, 21 are attached to the cylinder 10 and each contains an adjustable metering valve and a bypass valve for controlling the speed of movement of the piston 11. To this end a chamber 35 between tubes 26, 32 is connected to a chamber 36, which leads to the valve block 20, by a port 37, and a chamber 41 is connected to the valve block 21 by the passage 40 in the tube 33. Thus, opposite sides of the piston 29 are connected to the metering and by-pass valves. Opening and closing of the valves is controlled by a valve block 22. The piston 11 is moved pneumatically and the valves are pneumatically controlled whilst hydraulic fluid is displaced through the metering valves to control the speed of operation. Hydraulic fluid is stored in an accumulator 75 with a spring-loaded piston 76, the rod 77 of which protrudes to indicate the presence of sufficient liquid. Fig. 2 shows a metering valve in which a tapered spiral groove 66 communicates with a slot 67, adjustment being made by rotating the groove by a knob 68. The by-pass valve comprises a member 79 closed by a spring 81 and opened by pneumatic pressure acting on a piston 80. Closing a valve 54, which is operated pneumatically, locks the piston 11 in position. The metering valve may have an axial tapered groove rather than a spiral one. The control valves may be operated by any suitable system, e.g. mechanical or electrical trip devices operated by the tool carrier, or by an electronic pre-set beam or computer.

Title: Switching circuits

IPC: H02M3/156
Filed: 1967-11-17
Abstract: 1,209,168. Automatic voltage control. LITTON INDUSTRIES Inc. Nov. 17, 1967 [Dec. 2, 1966], No. 52534/67. Heading G3R. [Also in Division H3] The on and off transitions of a switch used in a voltage stabilizer are effected in response to the turn-on of one and the other respectively of the amplifying elements of a multi-vibrator having a diode in one of its cross-coupling paths. The turn-on is used since this is faster than the turnoff and the diode may be used to isolate the one output circuit of the multi-vibration from the other. In the D. C. supply circuit shown the output is stabilized by controlling the on-off ratio of a series switch transistor 12. This transistor is switched on by the switch-on of transistor 52 of a multivibrator 50, 52 and is switched off by an inverter 64 controlled by the switch-on of transistor 50, diode 62 isolating one circuit from the other. A bias capacitor charges negatively from 74 when 12 is off and the charge is used to assist conduction of 12 when 64 is switched on. Stabilization of the output voltage is effected by comparing in unit 28 the output voltage at 22 with a reference voltage at 34 derived from the output side (or the input side, Fig. 2 not shown) of switch 12. When the output voltage is within a given range the multi-vibrator free runs and a regular clipping of the supply occurs. Outside this range one or other of the multi-vibrator transistors is held conducting until the voltage is within the range. The output is smoothed by a filter 16, 20, 21 and free-wheeling diode 18. Either of terminals 22 or 23 may be earthed so as to provide a positive or negative supply at the other.

Abstract: 1,255,924. Cocking mechanism for guns. DEFENCE, SECRETARY OF STATE FOR. 29 Nov., 1967 [29 Nov., 1966], No. 53472/66. Heading F3C. A cocking mechanism for a gun incorporates a shaft 1 rotatably mounted in bearings 3, 4 carried by the gun cradle 5 and having two intersecting screw-threads, one a right-handed thread 6 of fairly slow pitch and the other a lefthanded thread 7 of twice that pitch. Mounted on the shaft 1 and restrained against rotation by engagement with a guideway 18 in the cradle 5 is a slide 19 which constitutes a retractor member and carries a forwardly extending hook member 20 for engaging a forward facing surface on the breech ring 21 of the gun 22 which can, thereby, be pulled rearwardly with the other recoiling parts of the gun. A hollow, cylindrical boss 23 formed on the slide 19 houses a cylindrical " half-nut " 24 having a raised thread portion 25 which locates in the grooves of the shaft's screw-threads. At each end of the screwthreaded part of the shaft 1 is a collar 26, 27 shaped to form a cam surface 28, 29 respectively, such that its engagement with the thread portion 25 will cause the " half-nut " 24 to turn about its axis and to be diverted from one screw-thread of the shaft 1 to the other. Starting from the rest position, clockwise rotation of a handle 8 mounted to the rear of the shaft 1 will cause the " half-nut " 24 to travel rearward along the screw-thread 6, carrying the slide 19 and the recoiling parts of the gun rearward against the action of the recoil return spring 30 to perform the required cocking action. At the rear end of the shaft 1 the "half-nut" 24 is caused to rotate so that the thread portion 25 is diverted into the thread 7. The recoiling parts then run out forwardly under the action of the spring 30 while the shaft 1 free-wheels relative to the handle 8 by way of a pawl-and-ratchet 17. During a firing sequence, the cocking action is performed by the recoil movement of the gun after firing the previous round. At the start of a firing sequence, however, the abovedescribed manual cocking action is performed. Various types of thread-engaging member other than a " half-nut " may be used, one example being a pair of nuts mating respectively with the two screw-threads on the shaft, with clutch means, reversible by contact with a bush at the end of its travel, for locking one or other of the nuts, according to the direction of motion, against rotation relative to the retractor member.

When the side frames are collapsed, the hinges align to allow the collapsed side frames to be swung towards one another about the hinges in the manner of a book. As illustrated, each cross-member has two hinges X and Y; however there may alternatively be a single hinge in each cross-member, Figs. 1-4 (not shown). In the case of those cross-members which are tubular, the hinge shown in Fig. 9 may be employed. Hinge members 16 and 17 linked by a pivot pin 20 are inserted in the tubes whose ends have edges 23, 24 and 21, 22 which abut in the erect and collapsed condition of the chair. In the erect condition, the hinge axes are not aligned so that the chair can be maintained erect by holding the side frames erect. This is effected by the engagement of a spring loaded sleeve 12 with a bracket 13 on a back leg 5. In a modification (not shown), a third frame may be rigidly connected to the centre parts of the cross-members to form a twin push chair.
