Title: Method of and apparatus for combating pests
IPC: A01M25/00
Filed: 1951-10-05
Abstract: 699,276. Making foam. ESSENER APPARATEBAU GES., and SCHURMEYER, F. Oct. 5, 1951 [Oct. 5, 1950], No. 23244/51. Class 47(ii) [Also in Group VI] Foam is produced by mechanically mixing a liquid containing a volatile pesticidewith a compressed gas by introducing the gas with a whirling movement into the liquid, and forcing the resulting mixture through a filter of porous and/or granular materials. Water containing pesticide stored under pressure in container 6 enters a mixing chamber 13 through a needle valve 11 and mixes with compressed air supplied through a control valve 14 to a pipe 10 which preferably enters the chamber 13 tangentially. The mixture is forced up through gravel or like filter material 8, the resulting foam leaving the apparatus through an outlet 15. According to a modification, the liquid storage vessel is separate from the foamproducing device, the latter being in the form of a gun in which the liquid and compressed air enter the mixing chamber from diametrically opposed openings controlled by a manually operated rotary valve. A suitable pesticide for use against rats is water containing scdium salts of p-chlorophenyldiazo-thiourea ferrous salts, size and fish albumen. Saponin may replace albumen as a foaming agent.

Title: Improvements relating to gas producers
IPC: C10J3/34
Filed: 1948-09-06
Abstract: 640,817. Gas-producers. WEST, Sir F. J., WEST, E., and WEST'S GAS IMPROVEMENT CO., Ltd. Sept. 6, 1948, No. 23381. [Class 51(i)] , In a gas-producer having a power driven rotary grate a bulb e containing expansible fluid is disposed in the water-jacketed lower wall d of the producer at about the level of the top of the ash zone, pressures on a diaphragm e<1> in a casing n being transmitted to a casing,h to control the speed of the grate and to a casing g for the protection of the bulb e. The control device in the casing h comprises a plunger o depressed against a spring p and provided with a peripheral groove q which with the pipes r and s forms part of the circuit of a hydraulic motor driving the grate, and a second plunger u normally supported by a cam v and formed with a slot v<1> so that the lever t connecting said plungers can accommodate movements of the plunger o by movements in the slot v<1> control of the motor speed being effected by the effective length of the groove q thus incorporated in the hydraulic fluid circuit. The automatic control may be thrown out of gear by rotation of the handwheel w, Fig. 3, to move the cam v thus freeing the plunger u and thereby balancing the two plungers, any movement due to the spring p being prevented by the simultaneous application of a brake shoe 10 on a drum 11. Rotation of the handwheel 12 can then be used to set the plungers and control the motor speed. Damage to the bulb e by excessive heat is obviated by withdrawal of said bulb due to movement of the casing g when pressure in the pipe m overcomes that of the spring i which bears against the casing g and the fixed abutment k.

Abstract: 766,437. Photo-electric densitometer. EVANS ELECTRO SELENIUM, Ltd., and COLLINS, G. C. Nov. 26, 1954 [Aug. 26, 1953], No. 23570/53. Class 40 (3). In apparatus for plotting a curve of optical densities of an object such as a filter paper which has absorbed dye in different quantities along it the object is scanned photo-electrically while a scale is traversed relatively to a surface, the photo - electric intensities being measured on a meter and plotted along the scale. As shown, the filter paper 1 under examination is held between two glass plates in a frame 8. The frame is suspended from a bar 17 which slides in guides 16 and which is connected to the scale 9 sliding on a surface on which a sheet of paper is attached on top of the instrument housing. A shroud 18 prevents entry of light to the housing at the point where the member connected to the scale enters it. A lamp 4 supported between leaf-spring terminals 24 mounted on plate 23 sends a beam of light through a slit 3, through the specimen 1, a filter 5 of colour complementary to that of the specimen, a sheet of glass 36 and on to a photo-electric cell 36. Between the source and the slit is mounted a cylinder 27 of glass or synthetic resin to diffuse the light evenly along the slit, and a light-adjusting shutter 11 pivoted about bearing 42 against the action of a spring (not shown) and adjusted by a screwed bar 47 from outside the housing. The photocell assembly may be pivoted about pin 36 out of the housing and a handle 40 is provided for the purpose. Spring-loaded balls 39 retain the cell housing in its operative or inoperative position. The photo-cell output is indicated on meter 7. In operation a sheet of paper is inserted under scale 9 and held by spring clips 41. With the zero light on the photo-cell the meter is adjusted to read zero. Slit 3 is then registered with a part of the filter paper free of dye and the lamp switched on. Shutter 11 is now adjusted to give maximum meter deflection. The filter paper is now traversed relatively to slit 3 at the same time moving the scale over the paper. The readings of the meter are then plotted along the scale or given a curve corresponding to the filter paper dye absorption. The test frame and marker paper could be connected in one movable housing and the scale fixed.

Filed: 1953-08-28
Abstract: 748,716. Protective arrangements. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Aug. 27, 1954 [Aug. 28, 1953], No. 23872/53. Class 38(5) A capacitor installation comprises at least one main capacitor 1, a simulating capacitor 4 which is smaller but of similar type to the main capacitor and disposed so. as to be subjected to similar life conditions save that its dielectric is more' highly stressed, and an indicating device and/or protective device for the capacitor 1 which is brought into action by a large current flow on the occurrence of an over-voltage breakdown of the capacitor 4. The capacitor 4 is in parallel with capacitor 1 and in series with a relay 3, the capacitor 1 being in series with a supply conductor 2. When relay 3 operates, a circuit-breaker 5 closes circuit 6 to shunt capacitor 1 and limit the voltage across it. A current-limiting impedance 8 in the circuit of capacitor 4 serves to shunt capacitor 1 when circuit 6 is closed. Where capacitor 1 is a shunt capacitor, the relay 3 may operate to open a switch and isolate capacitor 1 from the supply circuit. A pair of arcing contacts 1 may be provided in parallel with capacitor 4 between which a heavy current may flow on breakdown of the capacitor 4. The capacitor 4 may be mounted on the casing of capacitor 1 so as to be in good thermal contact therewith. Replacements 10 for capacitor 4 may be arranged to be subjected to the normal stress by variable resistor 11, so that when required for use they will have been subjected to the same life conditions as capacitor 1.

Title: Improvements in apparatus for reading marks of magnetizable material on records
IPC: G11B5/33
Filed: 1957-07-29
Abstract: 856,755. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 29, 1957 [July 28, 1957 (2)], No. 23896/57. Class 106 (1). Record cards with magnetizable marks are sensed by a gapped core 6 having a winding 10 forming part of a tuned electrical circuit which responds to different values of inductance due to the presence or absence of a mark at the gap 7. In the form of Fig. 1, the winding 10 is connected to a bridge T-filter composed of condensers 14, 15 and resistance 16. An oscillator 17 is connected between points 11, 13. The circuit can be tuned so that the impedance is a maximum when no mark is present, little or no current then passing through the filter. When a mark is present a voltage appears between points 12 and 13. This is applied through a resistance 18 to a diode 19, the signal on which is indicated on voltmeter V or passed to further equipment through condenser 21. In another form the core is used as a transformer core, an oscillator supplying a primary winding and a secondary winding being connected to an adjustable condenser. The voltage across this condenser is applied to the grid of a triode the oscillator being connected to the anode. The triode fires to give an output pulse when the difference between primary and secondary voltage reaches a predetermined level. This only occurs when a mark is present at the gap of the core causing the primary and secondary voltages to be almost 180 degrees out of phase. In the form of Fig. 4, the winding 37 on core 35 serves as the inductance portion of a Hartley oscillator 38, condenser 39 forming the capacitance. The frequency of oscillation is determined by the inductance of winding 37 which in turn is determined by the presence or absence of a mark at the gap 41. The frequency is normally 1500 kc. and higher when a mark is present. Change of frequency is detected by first multiplying the frequency by three in a multiplier-amplifier 42, thereby multiplying the frequency difference by three also. This output is applied to a transformer 47. The signal is passed from the transformer through an amplifier 46 and a transformer 48 to a frequency discriminator 49 designed so that when no mark is present the D.C. potential on line 50 is zero and when a mark is sensed the potential of this line is negative. This is amplified to give an output on line 58. A circuit 40 maintains the frequency of the oscillator 38 constant so that the normal voltage on line 50 is zero. For this purpose a connection from line 50 is taken through a delay to the grid of valve 51. The delay prevents corrections being made as the result of alterations of the potential of line 50 due to sensing a mark. Normally circuit 40 corrects the oscillator frequency to keep the potential on line 50 at zero. The card bearing the marks may be sensed in motion or while stationary.
