Title: Improvements in centrifugal separators
IPC: B04B1/20
Filed: 1929-11-01
Abstract: 337,965. Nyrop, A. Nov. 1, 1929. Density separators; discharging.-A centrifugal separator has co-axial relatively rotatable elements one of which carries a worm to expel sediment; the separator is driven by a single shaft in such a manner as to permit relative movement between the elements to render the worm operative. The nut 20 secures together the parts 15, 14 which are carried by the spindle 10; the part 15 may carry a pile 16 of discs, or a filter, and its upper end is fixed to a cover plate 17 provided with helical threads 3 which work on the inner surface of the bowl 4. The spindle 10 is connected to the driving shaft 1 by bevel gearing 6, 7, 9, and as a result of air friction or lag due to the inertia, of the liquid, the bowl 4 will rotate at a lower speed than the plate 17. The air friction may be increased by the provision of fins on the bowl 4, and retardation of the bowl may also be obtained by means of a mechanical or electromagnetic brake 55. The pitch of the helical threads 3 is increased as the diameter diminishes to prevent a decrease in the area of flow open to the solids. The liquid for treatment is admitted through the passage 40, and after treatment the light component of the liquid is discharged from the outlet 42, the heavy component through the outlet 41, while the solid material is carried by the worm 3 to the outlet 43. In the modification shown in Fig. 4. the bevel wheels 9, 6 are of different sizes, and the area of the helical thread 3 increases as its diameter diminishes. In other modifications the bowl is of cylindrical construction, and the bevel gearing is replaced by worm gearing. In the modified form shown in Fig. 8 a helical conveyer 25 co-operates with an inner screen 24 to assist the discharge of any solid matter which is lighter than the liquid dealt with; the outlet 43 may be regulated by means of discs 45, 46. The sludge outlet may be arranged at the lower end of the bowl.

Title: Improvements in or relating to means for determining the liquid content of materials
IPC: G01N9/36
Filed: 1937-12-02
Abstract: 506,996. Hygrometric apparatus. CHEESMAN, G. H., BURREN, F. J., and PIKE, R. J. Dec. 2, 1937, No. 33355. [Class 97 (iii)] Apparatus for measuring the moisture-content of material, such as sand, by mixing a sample with a definite volume of a testing liquid, which is miscible with the water, comprises a mixing device, in which a measure of defined volume for the material can be inserted and retained adjacent the mouth, removable closure means for the device, and a hydrometer for ascertaining the change-of density of the testing liquid resulting from the admixture with water. As shown a tube 1 with a level mark 2 for the testing liquid has a shoulder 7 on which the inverted measure 5 rests and is held by the bung 9. In a modification two caps are adapted to be fitted in turn by bayonet fastenings to a metal container. The first cap carries on its under side a measuring cup for the material and the second cap a pouring nozzle to enable the testing liquid to be decanted into a vessel in which its density may be measured. Acetone or alcohol may be used when estimating water content and carbon tetrachloride when estimating hydrocarbon oils.

Title: Improvements in or relating to electromagnetic clutches
IPC: F16D27/08
Filed: 1954-11-17
Abstract: 782,495. Clutch control. SOC. ANON. FRANCAISE DU FERODO, Nov. 17,1954 [Sept. 11, 1954], No. 33359/54. Class 80 (2). On a vehicle, an electromagnetic clutch the torque capacity of which varies with energizing current supplied by the vehicle generator, has mechanically controlled friction means operative during parking or emergency use to couple the input and output shafts of the clutch at a torque capacity slightly greater than that necessary to support engine compression. In Fig. 1 a graphited thrust block 82, contained within the clutchenergizing slip-ring 79, is actuated through a link 86, spring 85 and lever 84 to act directly on the clutch presser-plate 73 to engage the clutch. Actuation may be automatic by engine suction on engine-stoppage. In Fig. 4, not shown, the actuating member 84 has widely separated fork-arms extending outside the slip ring and bearing directly and frictionally on the presser-plate 73 so as not only to engage the clutch but also to apply friction braking to it to assist engine compression in holding the vehicle parked. In Figs. 2 and 3, not shown, a graphited thrust block like 82, Fig. 1, is moved axially by turning it about the clutch axis on a quick-pitch stationary screw-thread, actuation being by spring-returned Bowden cable. In Figs. 5 and 6 the iuput yoke 70 of the electromagnetic clutch is connected to the output shaft 76 through segmental clutch shoes 90 expanded by tangential springs 91 into frictional engagement with a surrounding drum 88 bolted to the input yoke. Pivoted centrally on the shoes are pawls 93 pressed by springs 94 inwardly into engagement with a ratchet 95 fast on the output shaft 76. The pawls overrun for forward drive F, but engage on reverse so that engine-compression parking is automatically obtained by engaging forward gear for a downgrade and reverse for upgrade. At idle and normal running speeds centrifugal force lifts the pawls 94 out of action.

Abstract: 441,312. Road vehicle lifeguards. LEMPERT, L., 66, Wellington Street West, Higher Broughton, Manchester. Nov. 21, 1934, No. 33440. [Class 103 (ii)] A vehicle lifeguard comprises a flexible sheet e of wire or textile fabric, leather &c. carried by a roller d mounted on a frame c at the front of the vehicle, the bottom edge of the sheet being connected to arms g carrying a heavy roller i at their front ends and pivoted at their rear ends on fixed brackets h, the ends of the axle of the roller i normally being supported by hooked extensions a<2> of a horizontally pivoted fender which when rotated on meeting an obstruction releases the roller i so that it falls under gravity or spring- pressure extending the sheet to catch the obstruction. The roller d may be spring- controlled or may be manually rotated to rewind the sheet. A pneumatic or solid rubber cushion k may cover the impact face of the fender. The guard may be used in combination with the brake mechanism described in Specification 438,393.

Title: Improvements relating to radio apparatus in which a variable condenser is provided with means for preventing dielectric breakdown thread at low atmospheric pressures
IPC: H03J3/20
Filed: 1957-10-28
Abstract: 852,361. Radio transmitting apparatus. MERLES, A. J. Oct. 28, 1957 [Nov. 28, 1956], No. 33592/57. Class 40(5). [Also in Group XXXVI] Relates to an arrangement for protecting a variable capacitor in a high frequency circuit from dielectric breakdown under conditions of low atmospheric pressure, e.g. in radio apparatus in high altitude aircraft. As shown in Fig. 2, the variable capacitor C1 is incorporated in a resonant cavity 1,11, and a D.C. potential of, for example, 150 volts is applied from a source S, decoupling resistor r, and a brush to the moving plates a the fixed plates b being returned to the source S via an earth connection. The application of the D.C. potential across the variable capacitor S is stated to considerably increase the height at which the aircraft may fly before dielectric breakdowns occur. A fixed capacitor C2 isolates the D.C. voltage from the high frequency circuit. The arrangement may include two capacitors C2 arranged one at each end of the rotor shaft of the capacitor C1 The movable plates are mounted on a spindle 2 of insulating material, Figs. 3 and 4, each end of the spindle having a concentric conductive ring 3 attached thereto. A capacitor C2 is mounted at each end of the rotor and is formed by a ceramic ring 5, Fig. 6, metallized on both faces as shown at e. A disc 6 of resilient metal is secured to one of the metallized surfaces e and is provided with inner lugs 7 which are biased outwardly so that contact studs 8 co-operate with the corresponding disc 3 to provide electrical contact between the rotor of the capacitor C1 and the capacitor C2. A metal cup 9, formed with an opening for the spindle 2, is secured to the other metallized face e of the capacitor C2 and is fixed to the cheek 4 of the capacitor C1. A lug 10 on the disc 6 provides a connecting point for the D.C. voltage the other pole being connected to the stator or to the cavity 1. In Fig. 4 the resonator is shown as having two elements 1 and 11 arranged one within the other the stator b of the variable capacitor being connected via contacts 12 to the element 11. An oscillatory tube is shown at 13 and a coil 14 and trimmer 15 are included for regulating purposes.
