Title: Improvements in machines for moulding and wrapping plastic material, for example, butter
IPC: B65B25/06
Filed: 1951-10-31
Abstract: 734,407. Wrapping butter &c. BRECKNELL, MUNRO & ROGERS, Ltd., and LAWSON, C. W. Oct. 31, 1952 [Oct. 31, 1951; June 24, 1952], Nos. 25406/51 and 15861/52. Class 94 (1). [Also in Groups V and VIII] Plastic material, e.g. butter, is fed through a nozzle 14 into a mould chamber 8 in an oscillating sector plate 1 (see Group V). The chamber is removable to allow different sizes of blocks to be formed. When the chamber is in a vertical position, a piston 10 is raised to eject the moulded block into an open-ended wrapping pocket 102. Prior to the ejection of the block, wrapping paper 200. Fig. 15, is drawn from a roll by rollers 203, 204 and a length is cut off by a movable knife 201 and positioned under the pocket on a platform 154 (see Fig. 12, not shown). The lengths of paper cut may be adjusted by a screw 214 which controls the movement of the roller 204. The jaws 106, 110 of the pocket are opened slightly by movement of an arm 108 to receive the block and the entrained wrapper. The sector plate is then moved back; the piston 10 wiping across the under face of the block. As the plate 1 commences its return movement, a wrapping member 126 is moved by a cam 132 to pass under the block and fold the rear of the wrapper against. the block. An arcuate plate 135 is then swung by means of a cam (not shown) on cam shaft 162 to bring its rear edge slightly beyond the front edge of the pocket to commence the folding of the front of the wrapper and to support the block when the piston is completely removed. The folding of the front of the wrapper is completed by swinging the pocket carrier 103 about a shaft 115 to cause the pocket to sweep over the plate 135. The projecting ends of the wrapper are then folded in at the rear end of the pocket by wings 137 on a swinging support 139 which is swung by a cam at a faster rate than the pocket so that the wings overtake the pocket and perform the rear folding operation. The undersides of the ends of the wrapper are then folded 'in during a dwell in the movement of the pocket by fingers 148, Fig. 11, which are moved inwardly by a cam 153. The folding of the wrapper is then completed by engagement with fixed deflector plates 155, 156, Fig. 9, which are adjustable laterally. Prior to ejection of the wrapped block, it is subjected to a consolidating pressure by a plate 167, Fig. 12A, operated by a cam 171. The pocket is detachably secured by a pin 114, Fig. 6, to the carrier 103, to allow it to be changed to match the particular mould chamber in use. Specification 672,742 is referred to.

Title: Improvements in and relating to thermionic valve circuits
IPC: H03F3/52
Filed: 1934-09-04
Abstract: 448,421. Valve amplifying circuits. BLUMLEIN, A. D., 7 Courtfield Gardens, Ealing, London. Sept. 4, 1934, No. 25497. [Class 40 (v)] To reduce the shunting effect of the input capacity of an amplifying valve together with the capacities of the source of signals and the wiring, the total conductance of the source 3 is made less than the control gridcathode admittance of the valve 1 at any frequency in the working range, the arrangement being such that the cathode potential of 1 varies in the same sense as the control grid, i.e. negative feed-back takes place through the impedance R. The output is taken from the cathode through lead 2. The capacity of the control grid connection is minimized by a tubular screen 9 directly connected to the cathode of cell 3 and to the valve cathode through a blocking condenser 5. Fig. 3 shows similar connections between an amplifier 1 and a photo-electric cell 3, in which stray capacity to earth of the screen 9 and other parts connected to the cathode of 1 is reduced by an external screen 13 which may also embrace the valve 1. The potential of the screen 13 is made to follow that of the cathode of 1 by connecting the latter directly to the control grid of an auxiliary valve 14, the cathode of which is connected to the screen 13. Valves 1 and 14 are of the screen-grid type, the screen grid potential being stabilized by gas discharge tubes 12 between screen grid and cathode. The resistance 15 and shunt condenser 16 are connected in series with the cell coupling resistance 6 to give enhanced response for very low frequencies (i.e. down to zero) to make the input at such frequencies large compared with random variations of battery potentials or valve characteristics. The coupling between the two succeeding amplifier stages, 17, 21, comprises a network 23, 22, 19, 20 which discriminates in favour of the higher frequencies to level the amplifier response characteristic ; inductance 23 corrects for high frequency loss due to stray capacities in the circuits of valves 17 and 21. The invention is mainly applicable to television amplifiers.

Title: Method and apparatus for conducting ionic exchange operations
IPC: C13B20/14
Filed: 1944-12-29
Abstract: 579,142. Purifying liquids. TRIGGS, W. W. (DorrCo.). Dec. 29,1944, No. 26130. [Class 46] [Also in Groups VI and XXXV] In a method of treating a liquid solution, for example, sugar juice, by passing it downwardly through a bed of ion-exchange material in a closed tank, the level of liquid in the tank is maintained substantially at the top surface of the bed by means which controls the pressure of a gaseous medium above the bed relatively to the flow resistance. In the construction shown, a tank 11 is provided with a perforated plate 16 supporting a bed D of exchanger material. Sugar juice passes upwardly under pressure through a pipe 23 provided with a weighted valve 29 and is dispersed over a perforated floatable baffle 51. The liquid level is maintained between limits L<1>, L<2> by photo-electric devices 61, 62, associated, respectively, with casings 57, 58 which communicate with the interior of the tank. The device 61 comprises a light-responsive relay unit 64 which is inactive as long as liquid in the casing 57 is above the limit L<2>, thereby obscuring light from a source 63. If the liquid falls below this limit the unit 64 is operated, whereby a solenoidcontrolled valve 67 is opened and pressure of gas in the tank 11 is released, allowing the liquid in the tank to rise. When the light ray through the casing 57 is again obscured the solenoid of valve 67 is de-energized and the valve is closed. The photo-electric device 62 is inoperative until the level of liquid rises above the limit Ll whereupon a solenoid-controlled valve 71 is opened, permitting compressed air from a pipe 72 to enter the tank 11 and depress the liquid therein. The tank 11 is supplied successively with sugar juice through pipe 37, regenerant solution through pipe 35 and water through pipe 39. The liquids are discharged by way of pipe 30, the juice flowing out through pipe 47, residual juice with wash water through a riser 31, regenerant solution through a riser 32 and excess back wash water through a riser 33. Back wash water is supplied to the tank through a pipe 41 and up through the bed D, the water raising the baffle 51 until it engages a ledge forming part of a launder 49, over which the water flows to outlet pipe 50. In a modification the photo-electric devices are replaced by floatcontrolled valves. If the level of liquid in the tank falls below the limit L' a float sinks to permit opening of a valve whereby air in the tank is allowed to escape. If the level rises above the limit L<1> a float raises a valve allowing compressed air to enter the tank. The air pressure in the tank may also be determined by the extent to which a valve in the outlet pipe of the tank is opened.
