Title: Gamma cameras
IPC: G01T1/164
Filed: 1971-04-21
Abstract: 1394053 Gamma camera NATIONAL RESEARCH DEVELOPMENT CORP 17 April 1972 [21 April 1971] 10447/71 Heading G1A [Also in Division H4] A gamma camera comprises an image intensifier 4 viewing a scintillation screen 2, the intensifier being switched on only when a predetermined amount of light which has been totally internally reflected from the main parallel faces of the scintillation screen is detected by one or more (e.g. six) photo-multipliers 8 disposed at the periphery of the scintillation screen. A lens system 3 may focus the light emitted from the main parallel faces of the scintillation screen due to an incident gamma ray on to the intensifier 4, the output screen of which may be photographed 5, televised or detected by an array of photo-diodes. The light which does not escape from the parallel faces of the screen is collected from the periphery thereof by a light guide 6 having a conical reflecting face 7 and directed on to photo-multipliers 8, the outputs of which are summed and pulse height analysed 9 to trigger the EHT switching unit 10 to energize the intensifier. This arrangement improves the cameras signal to noise ratio. The scintillation screen (e.g. sodium iodide or caesium iodide crystal may be embedded in light guide 6, as shown, or totally encapsulated within the light guide Fig. 3, (not shown) with a high refractive index fluid filling the gaps so that in addition to the light totally internally reflected within the screen 2 reaching the photo-multipliers 8 the light totally internally reflected at the air light guide interface also reaches the photo-multipliers. Instead of lens 3 a fibre optic bundle may be used preferably with a thin plate of small acceptance angle between the screen 2 and the bundle. A plate of lead glass may be disposed between the screen 2 and the image intensifier to reduce back-scattered gamma rays. A fibre optic bundle may couple lens 3 to the image intensifier.

Title: Improvements in and relating to the control of pick-ups in talking machines with magnetic sound recording on disc-shaped sound carriers
IPC: G11B3/38
Filed: 1948-04-16
Abstract: 647,854. Magnetic recording/reproducing systems. DAPHNE INVESTMENT TRUST. April 16, 1948, No. 10579. Convention date, Dec. 23, 1947. [Class 40 (ii)] A device for guiding a reproducing or recording head over a disc sound carrier in a'magnetic recording or reproducing machine comprises a second disc having a spiral groove therein co-operating with the reproducing or recording head. As shown in Fig. 1, a drive-shaft 1 is geared to a spindle 8 and to a revolvable shaft located on a pivot 6 for driving the sound carrier 5. The lower disc 11 of an electromagnetically-operated clutch mechanism is revolvably mounted on the shaft 8 and has a hole 12 for co-operation with a projection 13 on the upper disc 28 of the clutch. The sound carrier 5 is geared to the shaft 1 so that it makes a whole number of revolutions to one revolution of the shaft 8, thereby ensuring a constant starting position of the pick-up 22 on the sound carrier 5. The lower clutch disc 11 carries a gear 10 which co-operates with a guide disc 16 having a spiral groove 161 for co-operation with the pick-up 22. The disc 16 upon operation of the clutch is thus caused to rotate at a slower rate than the sound carrier 5 and the pick-up is guided over the surface of the disc 5. The disc 16 is rotated against the action of a spiral spring 17 so that at the end of playing, when the clutch is released, the disc 16 is rotated to return the pick-up to its starting position.

Title: Web-winder roll ejector
IPC: B65H19/22
Filed: 1966-03-11
Abstract: 1,096,128. Winding webs. FRANK W EGAN & CO. March 11, 1966 [Aug. 9, 1965], No. 10735/66. Heading B6B. In a two-drum web-winder, the completed web-roll R is ejected by a pusher 100 movable in the horizontal direction, Fig. 3, between parallel guides 113, with means for producing an air cushion between the web roll R and the pusher 100. The pusher consists of a bar of approximately trapezoidal cross-section (Figs. 9 and 10) having one side (101) machined concave to complement the curvature of the webroll R. A groove 102 communicates with a manifold passage (103) via a plurality of drilled passages (104). Compressed air is supplied to the manifold (103) via pipes and fittings (106). A curved deflector plate 107, pivoted to the bottom of the pusher 100, assists the initial wrapround of the leading edge of the web to a new core (Fig. 6). The pusher bar is pivotally located in a U-shaped frame comprising slide bars 110 (Fig. 8) and a cross-piece (111) by journal extensions 109. The slide bars have extension arms 114 which are clipped to a pair of parallel roller chains 115. The roller chains 115 are driven by a fluid cylinder (123, Fig. 1) via a chain (121) driving a sprocket attached to the shaft 118. In addition, the pusher 100 is rotated relative to the U-shaped frame by fluid cylinders 126. The web may be longitudinally slit by slitters (28, Fig. 1) and separated transversely by a spreader roller (29) before being wound. As the diameter of the web-roll increases, a riderroller 34, mounted between pivoted arms 33, moves upwardly, so that a core inserter 39 mounted coaxially with the rider-roller 34 picks up a new core 41b from a core loader 75. When the web-roll has attained the required diameter, the pusher 100 is moved towards the web-roll, and ejects the web-roll from between  the two winding drums and deposits it in the cradle formed by winding drum 14 and discharge roller 19 (Fig. 5). In the meantime, the core inserter 39 rotates, and as it approaches the horizontal position, the ends of the new core 41b engage cam surfaces 130 which are resiliently mounted on the rider roller arms 33. Continued rotation of the core inserter 39 urges the new core 41b into contact with the rotating rider-roller 34, thereby accelerating the core up to the speed of the running web. The rider-roller arms 33 then lower the new core into contact with the running web on the drum 13 (Fig. 6) with the pusher retracted, whereupon a knife mechanism 81 is raised to sever the web and blasts of air (96) wrap the leading edge of the web around the new core. The new core is then lowered into the cradle between the drums 13 and 14 (Fig. 7) and the completed web-roll R is deposited on to the slidably mounted tracks (24) of a roll-receiving table (22, Fig. 1). In an alternative (Fig. 13) two adjacent pusher bars (130 and 131) are used. The pusher bars may be changed in position relative to each other, so that the radius of curvature of the concave sides in combination may effectively be changed to suit web-rolls of various diameters.

Abstract: 1326343 Determining particle concentration in gaseous atmosphere SAAB-SCANIA A B 22 April 1971 [11 May 1970] 10779/71 Heading G1A An apparatus for monitoring the particle concentration in a gaseous atmosphere, such as described in Specification 1190490 and 1145657, is provided with a calibrating device 20 which has a standard dust-free surface 21, including a scattering pattern, 22 and an upper wall 26 which allows the passage of a fixed amount of scattered light. The device 20 may be swivelled within the apparatus housing, and for calibration purposes is moved into position with its lower surface 21 in the same plane as that assumed by the top surface of a plate (4d,) Fig.2 (not shown) during measurement thereof. Light from a constant intensity source enters the device 20 through two apertures 23, 24, after passing through a transparent dust excluding sleeve 28. Light scattered from the standard pattern 22 is received by a photo-cell whose output is displayed on a meter (16), Fig. 1 (not shown). The amount of light scattered out of the device 20 is then adjusted so that the meter reading achieves a predetermined level. This adjustment is achieved either by changing the size of an aperture (26b,) Fig.4 (not shown) at the top of the device, or by altering the number of diffusing plates 26a in the device.

Title: Improvements in modulation limiters for radio and like transmitters
IPC: G01R29/06
Filed: 1940-06-29
Abstract: 541,495. Valve modulating circuits; automatic volume control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 29, 1940, No. 11060. Convention date, June 29, 1939. [Class 40 (v)] Excessively deep modulation of a radio transmitter is prevented by automatically reducing the gain of the audio-frequency amplifier, whenever the modulating voltage applied to the plate circuit of the carrier amplifier exceeds a predetermined proportion of the D.C. voltage. The audio signal from a source 23 is amplified in the valve pair 19, 21 and applied by a transformer 13 to the plate circuit of the carrier amplifier 3. The secondary of the transformer 13 and the H.T. supply source 11 are shunted by a voltage-reducing potentiometer 43, 41, and the voltage at the junction is again split by a potentiometer 49, 53 of which one arm 49 is shunted by a large condenser 51. The voltage across the other arm 53 is applied to a diode 47 having its load resistor 39 connected as a bias resistor in the grid circuit of the valves 19, 21. The D.C. voltage at the diode cathode is a certain percentage of that of the D.C. source 11 as determined by the ratio of the variable resistors 49, 53 and 43, 41. The A.C. voltage at the cathode is the same as at the junction of the resistors 41, 43. When the latter exceds the former, a voltage is developed in resistor 39 and the gain of the amplifiers is suitably reduced.
