Abstract: 771,359. Treating mould materials. FOUNDRY EQUIPMENT, Ltd., and BEECH, A. S. March 22, 1955 [Dec. 22, 1953; July 23, 1954], Nos. 35609/53 and 21626/54. Class 83 (1). [Also in Group II] A mill for foundry sand &c. comprises a flexible endless-conveyer, a series of parallel mulling-rollers extending across the upper side of the conveyer, means directly beneath each roller for supporting the conveyer, and agitating-means between the rollers for mixing and turning over sand on the conveyer. As shown, the mill comprises mulling-rollers 49 above a conveyer-belt 11 supported by rollers 14, and scraper-ploughs 53 between the rollers. The ploughs are in groups and are staggered in successive groups. Some or all of the rollers are covered with vulcanized-rubber 59, Fig. 2. The spindles 48, Fig. 2, of the rollers are journalled in vertically-slidable axle-boxes 47 resting on rubber pads 50 carried by longitudinal anglebars 45 secured to uprights 41 which are secured to girders 18. Fixed side-walls 56, Fig. 2, above the conveyer prevent loss of sand laterally. The conveyer 11 passes around an adjustable idler-roller 13 and a roller 12 driven from a motor 40 by belt and chain gearing 39, 34. Sand to be treated is supplied to the conveyer from a hopper 57 and the treated sand discharged through a shoot 59. The ploughs may be replaced by other agitating means, and the rollers 14 by rigid supports. In a modification, . Fig. 4 (not shown), the mill comprises a number of superposed endless conveyer-belts each associated with mulling-rollers and intermediate scraper-ploughs, alternate belts being driven in opposite directions so that sand delivered from an upper conveyer descends on to a conveyer below it and thence on to a third or fourth conveyer. In this case, the roller axle-boxes are supported on helical springs. Water may be delivered to the sand as it leaves the feed hopper. Specification 405,515 is referred to.

Patent GB-869812-A (GB)
Title: Improvements relating to slotted waveguide aerials
Inventor: CARTER ARTHUR WILLIAM HENRY
IPC: H01Q21/00
Filed: 1956-11-27
Abstract: 869,812. Aerials. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 15, 1957 [Nov. 27, 1956], No. 36203/56. Class 40(7). A slotted waveguide aerial has all its slots arranged on one side of the centre line of a face of the guide and the slot spacing chosen, having regard to the wavelengths of the signal in free space and in the guide, so that a pattern with a single main lobe results. The slots in the embodiment shown are arranged with their lengths parallel to the guide axis 3 at S1-S11 and all on one side of this axis in a broader face, 4, of the guide. For this arrangement the angle # between the main lobe and the direction of transmission along the guide in a plane containing the axis of the guide and normal to the face 4 is given by: where # is the free space wavelength; #g, the wavelength in the guide; s, the slot spacing, and k a positive or negative integer. To prevent a possible solution when k = 0 the waveguide is filled with dielectric material so that #/#g is greater than unity and, to ensure a single main lobe, s is so chosen that there is only one solution available. If the dielectric used is polystyrene then #/#g #1À1 and for s = 0À6# there is a single solution with k = 1 which gives # as approximately 120 degrees. Other arrangements are possible depending on the dielectric used and the slot spacing. If these are chosen to give # = 90 degrees the aerial presents a resonant load to the feeder and the operational bandwidth is limited. In this condition a short circuit may be placed at the distant of the guide to act as a reflector and a ferrite insulator included in the feeder to reduce the effects of the variation in impedance with frequency. Other means; for example, irises; can be used to reduce the wavelength in the guide besides dielectric filling but in all cases care must be taken to ensure that no higher order propagation modes are possible in the guide. The length of the individual slots is approximately #/2 and the lateral displacement shown between them is to give a desired power distribution curve along the array. Where the waveguide is filled with a solid dielectric the aerial may be constructed by moulding the dielectric to the shape of the inside of the waveguide with protrusions corresponding to the slots. The surface of the moulding is then metallized, after which it is cased by electroplating, finally the metal on the protrusions, and possibly part of the protrusions themselves, is machined off to give dielectric filled slots flush with the surface of the guide.

Title: Improvements in or connected with springs for automobile and other axles
IPC: B60G11/36
Filed: 1920-12-29
Abstract: 176,919. Spence, W. L. Dec. 29, 1920. Saddle supports.-Relates to spring supports applicable to motor-cycle saddles &c. and comprising a pair of compound laminated springs formed of one or more through leaves A with reinforcing leaves A<1>, A<2> at each end on opposite sides thereof, the ends of the springs being rigidly bolted to the parts to be connected. According to the invention the springs are given a reverse initial set equal to half the full deflection due to load and impact so that in the normal static loaded position the springs are substantially straight. The invention is shown as applied to a rear-axle suspension for a motor vehicle, the springs being shown in the position of full deflection under load and impact in Fig. 2 and in the no-load or extreme rebound position in Fig. 3. The ends A<1> are longer and thicker than the ends A<2>. Total deflexion from the no-load to the extreme load and impact position involves a double reversal of camber of the springs, the fore and aft movement of the axle being reduced to a minimum. Auxiliary load and recoil springs B, C may be used, and a further spring D arranged either in tension or compression may also take part of the load, the end D<1> of the spring being weakened so that it is only effective for loads exceeding the normal. Specifications 7242/14, [Class 79 (ii), Motor vehicles, Driving &c.], and 389/15, [Class 108 (iii), Springs &c.], are referred to.

Title: Exhaust gas recirculation control for internal combustion engines
IPC: F02M25/07
Filed: 1973-08-01
Abstract: 1413023 Valves CHRYSLER CORP 1 Aug 1973 [2 Aug 1972] 36623/73 Heading F2V [Also in Divisions F1 and G3] An exhaust gas recirculation control system comprises an engine manifold vacuum source providing operating vacuum through a reservoir 22, Fig. 1 and control means 28 to an exhaust gas recirculation valve 10 and a carburetter venturi vacuum 12 source providing a control signal to the control means 28 to modulate the operating vacuum and vacuum relief means 50 responsive to both venturi vacuum and manifold vacuum to vent the reservoir 22 to the manifold vacuum level when the venturi vacuum achieves a desired relationship to the manifold vacuum thereby closing the exhaust gas recirculation valve 10. During operation the control means 28 amplifies the venturi vacuum control signal and a check valve 24 traps, in reservoir 22, high vacuum achieved at low speed or during deceleration. The venturi vacuum control signal in conduit 16 and chamber 42 controls the positions of linked diaphragms 36, 40 so that the diaphragm 40 controls the admission of vacuum from reservoir 22 to the recirculation valve 10. Venturi vacuum and manifold vacuum communicate respectively with chambers 54 and 56 so that a predetermined relationship causes diaphragm 52 to lift thereby venting the reservoir 22 back to the inlet manifold. In another embodiment the control means, reservoir and relief valve are combined in one housing. As the venturi vacuum in chamber 42, Fig. 2 increases a hook-washer 62 and diaphragm 64 move to open a port 66 communicating the reservoir 22 to the output conduit 30 via a chamber 68. As the vacuum in chamber 68 rises the force acting on diaphragm 40 opposes the force on the hook-washer 62, the port 66 being reclosed at the new higher vacuum level when equilibrium is re-established. When force on the hook washer is reduced output chamber 68 is vented through port 70 to atmosphere via chamber 72 and vent 74. Under wide open throttle conditions when venturi vacuum equals or exceeds manifold vacuum the relief valve diaphragm 50 lifts thereby venting reservoir 22 to the input 20 thereby relieving the output signal at 30 causing closure of the recirculation valve.

Abstract: 848,068. Washing granular materials. DE VEN, L. V. Nov. 25, 1957 [July 15, 1957], No. 36686/57. Class 82(2) A device for separating stones from a quantity of currants, raisins or similar fruit has no moving parts and comprises an inclined shoot 1, the upper end of which communicates with an element 2 for the supply of liquid and of fruit to be treated while the lower end communicates with a collecting member 3, the bottom surface of the shoot being provided with a number of partitions 4 extending across the shoot, each partition being at an acute angle relative to the bottom of the shoot in the upward direction of the slope, while said angle and the length of each partition are such that the free edge of each partition is at a distance from the bottom of the shoot which is equal to the average diameter of the fruit to be treated. The partitions may be formed by punching of a loose plate which is positioned on the bottom of the shoot; the device may thus be adapted to the treatment of fruit of different sizes by exchanging the plate for one in which the slope and length of the partitions are different. In operation, fruit to be treated is supplied with water to shoot 1 via element 2. Stones are retained by partitions 4 while the fruit is carried along by the flow of water to collecting member 3.

Title: Surface culture and filter membrane
Inventor: PEARCE THOMAS WILFRED
IPC: C12M1/12
Filed: 1955-12-22
Abstract: A flat porous membrane is prepared by casting a solution of cellulose acetate in a water-miscible organic solvent on a surface, and then heating at about 40-60 DEG  C. in a saturated or highly humid atmosphere to remove the solvent.  Glacial <FORM:0823050/IV (a)/1> acetic acid may be used as solvent.  To the solution there may be added up to about 5% by volume of one or more of water, a watermiscible glycol or other water-miscible alcohol, especially 2-2 1/2 % by volume of water and/or the same concentration of ethylene glycol or n- or iso-propyl alcohol.  Addition of up to 0.1% by volume of glycerol may be made.  The solution is preferably applied at about 30-60 DEG  C. to a surface at a temperature of about 40 to 50 DEG  C. In an example, a solution of 20 gms. cellulose acetate (acetyl value 35.0%) in 210 gms. glacial acetic acid is heated to 30-60 DEG  C. and applied (see Figure) to a glass plate 3, warmed to 40-50 DEG  C., and a straight edge 5 is then drawn along the stretched wires 1 and 2. The film thickness may be varied by changing the gauge of the wires or the concentration of the stock solution.  The film on the plate is then heated at about 50 DEG  C. in a covered water bath, keeping the plate above the water level, for about two hours.  The membrane may then be removed from the plate prior to drying, in which case a matt surface is obtained, or may be dried on the plate, yielding a glazed surface membrane.  Dyes may be added to the stock solution to produce coloured membranes.  A continuous process may be used for large scale production of the membranes.  Porous membranes obtained in this way may be used for the surface culture of bacteria and other microorganisms, or for the filtration of these organisms from liquids.
