Title: Apparatus for detecting the presence at a particular location of a substance of relatively low atomic number
Inventor: TOMKINS PETER KENNETH
IPC: G01N23/08
Filed: 1959-07-16
Abstract: 905,401. Automatic fluid level control systems. BURNDEPT Ltd. July 15, 1960 [July 18, 1959], No. 24509/59. Class 38 (4). [Also in Groups XVIII and XIX] Apparatus for detecting the presence or absence of a liquid 2 at a particular level in a tank 1 consists of a source 3 of beta radiation, e.g. strontium 90, disposed within the tank at that level, a target 6 which, in a steel tank, may be the wall thereof, but which, when the tank is made of a metal of low atomic number, e.g. aluminium, consists of a patch of lead or tungsten on the inner surface thereof and a detector 7 of gamma radiation which is emitted from the target as the beta rays are arrested therein. The detector 7 may be a Geiger counter or, as shown, a scintillating phosphor and a scintillation counter 8 which may include a photo multiplier. The output of the detector is applied through an amplifier 9 and a discriminator 11 to a rate meter 12 which may trigger a circuit 13 controlling an audible or visible indicator or the operation of a supply valve to the tank. In operation, when the level of liquid is below the line joining the source 3 to the target 6, a proportion of the abundance of gamma rays produced in the target impinge on the detector. When the level rises so far that the liquid 2 is interposed between the source and the target a much less intensity of gamma rays is produced in the liquid and the large diminution in gamma radiation received by the detector gives rise to the warning or controlling signal. The apparatus may also be used to detect flaws in a coated sheet, the source 3 and detector 7 being moved together along opposite sides thereof.

Title: Colour television receiver
IPC: H04N11/08
Filed: 1953-09-04
Abstract: 755,851. Television. STANDARD TELEPHONES & CABLES, Ltd. Sept. 4,1953 [Oct. 20, 1952], No. 24537/53. Class 40 (3) In a sequential colour television receiver the high-frequency components in the received video signals which represent a change from one coloured area to another are employed to control the generation of blanking signals for application to the beam controlling electrodes of the picture reproducing tube. This produces a thin black line of demarcation around the perimeter of differently coloured areas and thus increases the apparent definition of the received picture. As shown in Fig. 1 a H.P. filter 7 selects the high-frequency components which occur when the colour signal undergoes a sudden change in level and after phase inversion in 8 these components are differentiated in 8a and then rectified and suitably shaped in 9 and 10 respectively to provide the blanking signals for application to the control grid 11 electrode of picture tube 6.

Abstract: 718,158. Feeding webs. MARKEM MACHINE CO. Oct. 7, 1952 [April 29, 1952], No. 25076/52. Class 100 (1). A means, to feed strip material intermittently over a table, comprises an elongated slide mounted for reciprocating movement in the direction of its length in guiding ways provided in the table, the strip being gripped during feeding between a strip-gripping member carried by the slide and a lip on the slide. As shown, a strip 2 is fed over a table 1, Fig. 3, by means of a longitudinally reciprocating slide 3 and a gripping member 7 positioned within a groove 6 of the slide 3. The slide 3 is reciprocated in a guideway 4, by a lever 13, Figs. 2 and 3, pivoted to a boss 14 attached to the slide 3. The lever 13 has a pin 18 extending through an opening 19 into a slot 20 in the member 7, the lower end of the lever being connected to an actuating member 15. The gripping member 7 has a plurality of inclined surfaces 10 co-operating with pins 11 on the slide 3. When the member 15 moves to the right as seen in Fig. 2, the lever 13 moves forwardly, thus moving the member 7 relatively to the slide 3, such that the member 7 is raised to grip the strip between a lip 5 and a surface 9 of the member 7; thereafter the member 7 and slide 3 advance with the strip in unison. The strip is released on reversal of the member 15. When a registered feed 'is required, the strip is fed forwards beyond the required position and is then retracted by a spring arm 27 until a spring-pressed member 22, Fig. 5, engages a registration notch 23 in the strip, the spring arm 27, Fig. 2, being secured to the lever 13 at one end and engaging the strip at the other end.

Abstract: 1,008,558. Block-bottom valve bags. WALTER DURBECK PAPIERSACKFABRIKEN G.m.b.H. June 29, 1962 [June 30, 1961; Aug. 5, 1961; Jan. 8, 1962], No. 25157/62. Heading B8K. [Also in Division B5] At least two corners of a valve sack formed from gussetted tube are welded, as at 17 (Fig. 14) so that the inturned portions of the gussets are welded to the side wall, but not to one another, as indicated in Fig. 15; these welds ensure that the sack takes up a block form when filled. Three of the corners may be treated in this way, and a valve is formed by folding in the remaining corner about the line x-x (Fig. 1) to form the equivalent of one end of a diamond fold. The ends 15, 16 (Fig. 14) of the bag are welded. These welds may be interrupted adjacent the gussets, where the welds 17 provide a complete seal, or, alternatively, the welds 15, 16 may be produced to the edges of the tube and the welds 17 formed as spot welds. The valve corner may be formed with a slit 12 (Fig. 10) to provide a long valve 8, 9, or an extension may be secured on to the portion 8, 9. An insert may be welded over the valve corner, when this is opened out as shown in Fig. 12, and this insert may extend outside the bag to provide a valve portion which can be bent over for sealing. The bags may be welded and cut from plastie tube as indicated in Figs. 16 and 18, so that extensions 8, 9 are left at the valve corners. The weld 16 (Fig. 16) is preferably made only after the tube has been opened up, the valve folded in, and the tube closed again. The tube may be laminated of different materials.

The apparatus shown is for supplying a fuel-air mixture to an internal-combustion engine but the invention is applicable to purposes such as humidifying, vaporizing medicines or spraying insecticides. The air enters through filter 60 and flows through a venturi 44 to the compressor inlet, the compressed air passing through apertures 56 in a plate 34 to the annular space 36 in which it follows a helical path guided by a baffle 40. Condensed liquid collecting in chambers 140, 142 is returned to the air stream by suction through pipes 150, 152. The compressor 28 is on the same engine driven shaft 26 as a pump 20 suppling atomising air to the atomiser 76. The mixture is delivered through pipe 160 to an engine intake pipe 170, Fig. 1A, the valve 164 being controlled conjointly with the throttle valve 178. Spring plates 52 are opened by suction to permit some of the mixture from chamber 36 to be recirculated through apertures 42, 55 back to the compressor 28. The atomiser 76, Fig. 4, comprises a passage 86 supplied with compressed air by the pump 20, the air escaping through holes 88, 89, drawing fuel from a supply pipe 74 and passing it through orifices 96, 98, the fuel particles being further atomised by a spring plate 102. In a modification the fuel is supplied to the atomiser by a fuel pump. In Fig. 10 the air flows to the compressor through inlet pipe 328 and is discharged through pipe 308 into a circular chamber 300, atomised fuel being injected at 322. The air and fuel are guided into circular flow by a baffle 316. The resultant mixture passes through a filter 360, Fig. 11, into the engine intake pipe having interconnected throttles 364, 368, with secondary air inlets 380 there between.
