Abstract: 744,306. Onions &c., topping and tailing. BRIERLEY, COLLIER & HARTLEY, Ltd., W. March 19, 1954 [Dec. 22, 1952], No. 32388/52. Class 28(2). [Also in Group XXX] Onions &c., 12 to be topped and tailed are each placed in the arcuate gap 11 of cradles 7 on an endless conveyer chain 5 and are held in position by a spring 9 extending from the adjacent cradle whereby the onion, after passing through spaced pairs of scissor blades 20, 22, is released as the cradle rounds its sprocket 13 to free its spring 9 from holding position. The onion is further held down in its cradle by a press shoe 40 under the action of a spring 41, which action is limited by an adjustable stop 43. The lower cutter blade 12 is swung upwards about its pivot 19 towards its cooperating fixed blade 20 by the downward rotation of pins 34 on an intergeared pin wheel 33, each pin 34 engaging the roller 38 on a lever extension 23 of the blade 22. The tops and tails are guided into the space between top and bottom gripper plates 18, the gripping action taking place by first automatically moving each pair of plates 18 horizontally away from the onion and then releasing them to close in endways on the onion by spring pressure 17, Fig. 4 (not shown), thereby holding the onion securely in its cradle 7 by end pressure at the top and tail. The scissor knives 20, 22 similarly move apart horizontally and then close in over the tops and tails just before making the cuts. For this purpose the guide and gripper plates 18 and the knives 20, 22 are slidably mounted in a frame 14 the sliding apart being effected by pins 30 on a pin wheel 13 pressing apart levers 36 attached to the sliders. Specifications 650,653 and 727,589, [Group XXX], are referred to.

Title: Improvements in or relating to underwater breathing apparatus with automatically controlled inlet and exhaust valve
IPC: B63C11/22
Filed: 1960-09-21
Abstract: 957,978. Respiratory appliances. A. NOVELLI, and P. BUGGIANI. Sept. 21, 1960 [Oct. 10, 1959], No. 32418/60. Heading A5T. In an underwater breathing apparatus the pressure-sensitive member controls the operation of both the inlet and exhaust valves, and the valve mechanism is enclosed within said member. Two plate members 1, 2, hinged at 3 and connected by a flexible member 4, form a closed chamber which expands and contracts in accordance with the user's respiration, being connected through a duct 5 with a mouthpiece 6. The end 14 of a gas inlet tube 13 forms a seating for a valve 15 mounted on one end of a lever 16 pivoted on a pin 19 and a second lever 18, on the same pivot, carries the exhaust valve 10<SP>1</SP> for engagement with a seating 9 on an exhaust conduit 7. The two levers 16, 18 are connected at their free ends by a spring 17. At inhalation, the member 1 is drawn towards member 2 and bears on an adjustable pin 23, so as to tilt lever 16 counterclockwise and open the inlet valve. Gas continues to be admitted until, at the end of inhalation, the member 1 moves upwards and allows the inlet valve to close. It remains in this position until the user exhales, whereupon it moves further away and a link 20, engaging under the lower lever 18, opens the exhaust valve, the movement being permitted by compression of the spring 17. At the end of the exhalation the spring 17 lowers the lever 18 and seals the exhaust port. A flap device 22 is carried on the valve disc 10 and is engageable by the lower end of the link 20. During inhalation this link is lowered, as in Fig. 1, and the flap is bent downwards so as not to interfere with the free passage of gas, but, during exhalation, the flap is allowed to rise to the position shown in Fig. 2, where it serves to deflect exhaled air towards the exhaust port. The arrangement also provides for the initial part of the exhalation, which is relatively free from carbon dioxide, being trapped within the chamber while the latter part passes to the exhaust port. It is subsequently breathed in again with the next inhalation.

Title: Improvements in or relating to Photoelectric Devices for Creating Electric Impulses
IPC: G01D5/36
Filed: 1967-07-14
Abstract: 1,176,953. Measuring movement. ERNST LEITZ G.m.b.H. 14 July, 1967 [16 July, 1966], No. 32520/67. Heading G4H. [Also in Division G1]  A photo-electric system for measuring displacement is arranged to produce four-phase signals which permits suppression of the D.C. component due to the background illumination level. The apparatus utilizes a grating arrangement comprising either a single, reflecting amplitude grating having alternate reflecting and transparent lines, one portion of which is imaged on to another portion, or two amplitude gratings, the first being imaged on to the second which is a reflecting grating. In the figure, a lamp 10 illuminates a first portion of grating 13 which is movable. The light from this first portion is imaged on to a second portion of the grating by means of lens 14, pentagonal prism 15, a Wollaston prism 16 splitting the beam into two mutually perpendicularly polarized beams, beam splitting cube 17 and lens 18. The light transmitted by the grating is detected by photo-cell pair 29, 30, the two differently polarized beams being directed to these cells by polarizing beam splitter 26. The light reflected from the grating passes through cube 17 and the two differently polarized beams directed by polarizing beam splitter 31 to photo-cells 34, 35 producing output signals of opposite phase to the signals from respective photo-cells 29, 30 due to the phase change on reflection at the grating. The signals from respective cells in each pair are themselves phase-displaced with respect to one another due to the action of the Wollaston prism so that the signals reaching push-pull amplifiers 36, 37 represent a four-phase field. The D.C. component in the outputs of these can be supressed or that of either amplifier e.g. 36, used to control the lamp intensity to compensate for collection of dust or dirt thereon or on the gratings. A discriminator 38 determines the direction (add or subtract) in which counter 39 is to count pulses arriving from the amplifiers. The beam splitting cube 17 is mounted on a pivoted arm 20 which may be oscillated by an electromagnetic arrangement 22-25, so as to provide a cyclically variable light beam.

Title: Machines incorporating a plurality of engines
Inventor: WARNE EUGENE HAROLD
IPC: B64D37/16
Filed: 1960-09-22
Abstract: 911,117. Engine turning gear. LUCAS (INDUSTRIES) Ltd., JOSEPH. Sept. 7, 1961 [Sept. 22, 1960], No. 32557/60. Class 7(5) [Also in Group XXVI] In a machine of the kind incorporating at least one main engine and at least one subsidiary engine in which each engine is coupled to its own fuel pump of the swash plate type, means are provided whereby excess fuel from the fuel pump driven by the main engine can be directed to the fuel pump of the subsidiary engine so as to cause the latter pump to function as a hydraulic motor until the subsidiary engine has started. The invention is applicable to an aircraft having a main engine for producing forward thrust and a subsidiary engine for producing vertical thrust, the latter engine being stopped when the aircraft is in normal flight. The fuel pumps of the two engines are indicated at 1 and 2 respectively, the pumps taking their suction from fuel tank 4 and delivering through outlet ducts 9 and 11 respectively. When it is desired to re-start the vertical engine, the valve 8 is opened and excess fuel being delivered by the pump 1 passes through duct 7 to the inlet 5 of the pump 2 and the pump is driven as a hydraulic motor and rotates the vertical engine. A non-return valve 6 is disposed in the duct 3 connecting the tank to the inlet of the pump 2 and prevents fuel in the duct 7 from passing back to the tank. The pressure of the fuel in the duct 7 also acts on the piston of valve 18 to maintain the valve closed. Fuel is delivered through outlet 11 by the pump 2 when acting as a motor, one portion of fuel passing to the fuel system of the vertical lift engine and the other portion passing to the relief valve 12 and through the port 16 to the low pressure part of the fuel system. When the vertical lift engine starts, the increased suction in the duct 7 causes the valve 18 to open and also allows the pump 2 to take its suction from the tank 4 through the non-return valve 6. Opening of the valve 18 places the top of the piston valve 14 in communication with the lower side thereof, and the valve 14 is closed by the spring 15, the whole of the delivery of the pump 2 then passing to the engine fuel system.

Title: Method of preparing contact catalysts
IPC: B01J37/02
Filed: 1932-11-23
Abstract: Catalysts are prepared by levigating a carrier in the presence of a salt of nickel, cobalt, or copper, adding a carbonate to precipitate the metal, and subsequently reducing the precipitated carbonate in situ on the carrier.  According to an example, 100 parts of kieselguhr are levigated in a ball mill with a solution of 100 parts of nickel nitrate in 100 parts of water.  The resulting cream-like paste is heated to 70-80 DEG  C. and 60 parts of sodium bicarbonate in 260 parts of water are added.  The mass is filtered and the filter cake is dried and reduced in hydrogen, carbon monoxide, or methanol or ethanol vapour at about 450 DEG  C. Other carbonates or bicarbonates such as those of potassium, lithium, and ammonium may be used as precipitants instead of sodium bicarbonate.  Other carriers which may be used are asbestos, glass, mineral wool, pumice, clay, &c.  The catalysts are useful for hydrogenation, alkylation, and the synthesis of oxygenated compounds.

Filed: 1935-11-30
Abstract: 461,930. Delivering material from hoppers. SIMON, Ltd., H., and BRIAN, J. C. Nov. 30, 1935, No. 33268. [Class 78 (i)] In apparatus for controlling the flow of materials from hoppers automatically in accordance with upper and lower limit heads of material, a swinging outlet valve b, pivoted at h, carries an arm g which can be set nearer to or further from the weighted lever d by the hand-operated screw f pivoted to the lever d. A pointer moving over a scale indicates the setting, which varies the initial position of the valve. The lever d is pivoted at e and normally hangs vertically. When the height of the grain in the hopper falls sufficiently to release a pivoted plate o and allow it to be restored to a vertical position by the counterweight r, the counterweighted arm u is also released by the roller t and swings to raise the link wand thus move the valve b towards the right to partially close and diminish delivery. On the other hand, when the level of the grain rises so that it presses on and displaces the upper member p, the link z is raised to open the valve further. A slot 2 permits the plate o to ftmction without disturbing the rod Z. Switches 3, 4 may both actuate alarms and in the case of the upper switch 4 may cut off the feed to the hopper. In a modified construction the member o is lower down in the hopper and on the same side as the member p but the action is similar to the form described.
