Spray carburettors.-The carburettor body comprises two portions 1, 2 secured along a joint X, Y by a cap nut 11 and bolt 8. The float chamber contains a filtering screen 3 with a solid bottom 4 carrying a rod 6 which forms a guide for the float. Fuel passes through a duct 19 to the main and slowrunning nozzles 21, 28 and, on its way, mixes with air admitted through ducts 27 and tube 9 in the float chamber. The main nozzle extends upwardly through the part 1 and a choke tube 13 therein. The slowrunning nozzle enters a recess in the part 37, Fig. 3, below a sleeve 48 having an aperture 49 therein which is controlled by a needle valve 50. The sleeve 48 has an aperture opposite a bored plug 52 and another 61 adjacent a conduit 34 which communicates with the discharge conduit 33. Fig. 1. on the engine side of the throttle valve 15. In a modification, the upper and of the nozzle 28 is surrounded by a rotatable sleeve having apertures of different sizes which may be made to register with the conduit 34.

Abstract: 457,789. Food preparations; medicines. GOODALL, C., Park Lane, Tutbury, Burtonon-Trent. June 5, 1935, No. 16315. [Classes 49 and 81 (i)] [See also Group I] Fresh grass is subjected simultaneously to a cutting, lacerating, or like operation which serves to facilitate the removal of entrapped juices, and to a squeezing operation which effects removal of the said juices. As shown, the grass is passed between heavy rollers a formed with circumferential V-shaped ridges b, the ridges of one roller registering with the troughs of the adjacent roller. The juices collect in the sump d and the grass is discharged over the shoot f from whence it is taken to a hot air drier. The dried grass is then baled or otherwise stored. The juices contain chlorophyl, vitamins and ferments which are extracted by any suitable means. The juices may be evaporated to dryness or partially evaporated, the product being used for nutritive or medicinal purposes. According to the Provisional Specification, vegetable substances other than grass mav be treated. Grass is first passed through a mincing-machine like a chaff cutter wherein it is cut into short lengths and crushed. The product is then passed to a screw-operated squeezer to separate the juices. The grass may merely be crushed by the squeezer.

Title: Improvements in or relating to electrical contact devices
IPC: H01H1/22
Filed: 1923-06-25
Abstract: 215,998. West & Co., Ltd., A., and Page, G. June 25, 1923. Contacts.-Self-aligning contacts which, when contact is made, turn about a fulcrum in opposition to a spring so that considerable contacting pressure is obtained, are constructed so that when out of contact they possess a definite alignment and when contact is made they first pivot about a fulcrum which retains them in their alignment and later about a second fulcrum which allows them universal movement. In the construction shown in Fig. 4, a semi-cylindrical contact 5 is carried by a member 4 having fixed to it a pin 15 which fits loosely in holes 16 in fixed side plates 20. When a drum contact 24 is rotated into engagement with the contact 5, the member 4 pivots about the. pin 15 against the action of a spring 17 until a ridge 19 on the member 4 engages a fixed strut 12 whereupon it pivots about this lower point and allows the contact 5 to align itself correctly. Fig. 1 shows the invention applied to a moving contact of a switch. When the arm 1 is swung either to right or left so that a semi-cylindrical contact 5 engages a fixed contact 18, the channel shaped contact carrying arm 4 pivots first about one of two pins 15 fixed to it and engaging holes 16 in side plates of the arm 1 and then about a rive't head 19 which engages a strut 12 and allows universal motion.

Title: Improvements in or relating to multi-stable-state valve circuits
Inventor: UTTLEY ALBERT MAUREL
IPC: H03F1/36
Filed: 1949-06-22
Abstract: 670,043. Valve circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 1, 1950 [June 22, 1949], No. 16587/49. Class 40 (vi). An electronic trigger circuit having at least three stable conditions comprises a D.C. coupled amplifier in which the output voltage bears a known relationship to the input voltage and in which two positive feed-back channels provide feed back at two different output voltages which lie above and below a datum level so that the trigger circuit is driven by an input signal to assume a stable condition where the output voltage lies above, below or between the two different output voltages. The Figure shows a trigger circuit comprising two D.C. coupled amplifier stages V1, V3 and cathodefollower stages V2, V4 in which the triggering control current which may be positive or negative is applied to the grid of valve V1 by means not shown and in which the output is taken from either the cathode of valve V2 or V4. Unconditional negative feed back is applied to valves V1 and V3 via resistors R6 and R19 respectively. Conditional positive feed back dependent upon the voltage at the cathode of valve V2 is applied to valve V1 via diodes D1, D2 and conditional positive feed back which is dependent upon the voltage at the cathode of valve V4 is applied to valve V3 .via diodes D3, D4. Resistor R13 provides the forward coupling path between the two amplifiers. In the normal stable quiescent condition all the diodes are non-conducting and the voltages at the grid of valve V1 the cathode of valve V2 and the grid of valve V3 are approximately equal. If a positive triggering current is applied to the grid of valve V1 a positive output signal is obtained from valve V4 and when the cathode voltage of valve V4 exceeds the 'voltage across resistor R24 diode D4 conducts and completes the positive feedback loop to the grid of valve V1. As the loop gain is greater than unity the voltage at the cathode of valve V2 moves increasingly negative until diode D1 conducts when the positive feed back is overcome and the circuit moves to a stable condition. If the initial triggering current flow to valve V1 had been negative a similar action would have occurred but diode D3 would have been rendered conducting to give positive feed back when the cathode of valve V4 moved sufficiently negative and the action would then have been limited by diode D2 conducting to bring in a negative feedback path. To revert the circuit to its quiescent stable state the positive feed-back loop is interrupted by applying, for example, a positive pulse to the cathode of diode D3 and a negative pulse to the cathode of diode D4 through suitable rectifiers. Triggering of the circuit may be carried out by feeding negative current to the grid circuit of valve V1 for triggering in one direction and by feeding negative current to the grid of valve V3 for triggering in the other direction. The triggering pulses may be fed in via buffer gating stages.

Title: Improvements in or relating to float-operated valves for controlling the supply of liquids
IPC: F16K31/18
Filed: 1959-05-14
Abstract: 948,001. Valves. R. F. BALL, and P. M. HANBURG. May 13, 1960 [May 14, 1959], No. 16615/59. Heading F2V. A pivoted float 1, Fig. 1, for controlling the supply of fluid to a container, such as a lavatory cistern, has a buoyancy moment 4 about its pivot 3 which is less than the sum of the counter moments when the float is in its lowermost position and increases with the extent of immersion until the float is caused to rise by turning about its pivot. The counter moments consist of the gravity moment 5, a moment 6 due to the friction of the pivot and the valve, and a moment 7 due to liquid flowing through a tube 2 constituting the arm of the float. As the liquid level rises the provision of a counterweight 8 and the proportions of the float 1 ensure that the rate of increase of the buoyancy moment 4 exceeds the rate of increase of the sum of all other moments so that the float moves rapidly through an angle of 40 degrees when the moments are again in equilibrium. In Fig. 4, the float comprises a hollow rectangular body 16 moulded to a weight 18 and provided with a rectangular cup 19. When the latter begins to fill, the float swings quickly about its pivot 12 to close the inlet 10. Valves in the bottom of the cup allow it to drain when the liquid level falls. The arm 14 of the float, which may be of polyethylene or thin sheet metal, is hollow to permit liquid from the inlet 10 to flow into the container. The Specification gives dimensions for a float and values for the moments.
