Abstract: 700,128. Cleaning abrasive discs. BUDD CO. July 25, 1951 [July 29, 1950], No. 17615/51. Class 60 The abrasive surfaces of discs or belts are cleaned by blowing live wet steam under pressure against the fouled surface for such a short time that no deleterious wetting of the surface takes place. The abrasive surface is preferably moving at high speed. An abrasive disc D is pressed into contact with motor driven rotating face plate 13, e.g. at 1,750 r.p.m., by head 33, which is freely rotatable in mounting member 14, while steam is injected at 115 p.s.i. through nozzle 18, so that fouling and moisture are thrown off by centrifugal force. The member 14 is retractable by a pneumatic piston which causes the treated disc to jump off spindle 34 and roll to a collection basket. Head 33 is braked in the fully retracted position by segment 38 to enable a further disc D to be placed on central spindle 34, and the retraction of member 14 automatically cuts off the steam supply to nozzle 18. Water may be supplied to or removed from the steam as desired.

Abstract: 1,234,852. Semi-conductor device. MARCONI CO. Ltd. 8 April, 1969 [16 April, 1968], No. 17777/69. Heading H1K. A semi-conductor transducer for converting varying magnetic field intensities into electric signals comprises a body of N-type semiconductor material having a P-type region formed in one end to which region a contact E is attached, a further contact B attached to the opposite end of the body in ohmic contact with a more highly doped part of the N-type region, and two P-type regions formed on opposite sides of the body, between contacts E and B, and having contacts C1 and C2, so that with no external magnetic field minority carriers injected into the N-type body from contact E pass equally to contacts C1 and C2, but with an impressed magnetic field this balance is disturbed. The body may be of germanium or silicon of sufficiently high resistivity to cause the current between contacts E and B to produce an electric field along the fillament thus increasing the minority carrier diffusion length. In a second embodiment, Fig. 3, not shown, a further contact (B2) is added, on the other side of contact E from the other contacts, to allow an electric field to be impressed in the P-type region to enhance the diffusion of carriers from contact E towards contacts B to ensure carrier collection along the whole length of contacts C1 and C2 with no external magnetic field present. Contacts C1 and C2 may be offset compared with contact E, or may have unequal impedances connected externally to balance the transducer at given values of magnetic field other than zero.

Abstract: 112,032. Brunton, J. L., and Brunton, W. P. Dec. 12, 1916 Ballasting and trimming; pumping plant, arrangement of; leakage, removing. -The ordinary pumping plant for ships' drainage &c. is adapted for the purpose of saving a torpedoed or damaged ship by supplying water into one or more compartments on the opposite side or end of the ship to the damaged compartment.in order to trim the ship. The arrangement can also he utilized for supplying oil to the tanks of oii ships. The m a i n feature consists in the provision of a by-pass k between the pump suction pipe b, connected through a suction-valve box c and pipes d to the holds. and the discharge pipe h of the ballast pump a. A pipe f with a valve g connects the .suction pipe b to the sea. Valves l and m also are fitted. When it is desired to flood some of the holds, a bridge or guard p over the combined stop and check valves e fitted with screw pins a is turned down about the pivots q to allow the desired valve e to be set open and the others closed, the box c then acting as a discharge box. The valve m and the valves in the distribution box i are then closed, and valves 1 and g opened. The pump a can then pump water from the sea into the holds. The ballast tank nearest the damage can be connected at r to the by-pass pipe k so that, with the proper adjustment of the valves, the pump can transfer water from one side or end of the ship to the other. The valves l, m, and g are of the screwdown lift kind shown in Fig. 4, wherein a locking- cottar w, arranged over a cottar s passing through the valve spindle, locks the valves in the closed position.

Title: By-pass control device for use in automatically by-passing a hydraulic unit or the like
IPC: F16K17/32
Filed: 1944-09-27
Abstract: 582,374. Fluid-pressure servomotorcontrol systems. ARMSTRONG SIDDELEY MOTORS, Ltd. (Wills, H. P.). Sept. 27, 1944, No. 18445. [Class 135] A device for automatically byepassing a hydraulic unit or pipe-line in the event of damage and leakage, is described with particular relation to the oil cooler for an aircraft engine. As shown diagrammatically in Fig. 1, the scavenge return 8 from the engine passes through a valve,7, an oil cooler 9 and thence to the reservoir tank. In the event of damage to the oil cooler resulting in a drop in pressure in the scavenge return line 8, the valve 7 is actuated to stop the supply to the cooler and direct it through a byepass line 12 to the reservoir. This operation is controlled by a servo-device 10 to which the engine oil supply is connected through a line 21 and to which a connection 18 from the scavenge return line is also taken. The scavenge return pressure acts through a nipple 19, Fig. 2, on to a piston 15 to maintain it in the position shown against a spring 17 to close by means of a piston valve member 16 the supply of engine oil under pressure from the line 21 and nipple 22 to a spring-pressed plunger 26 for actuating the byepass valve 7. On a fall in the scavenge line pressure, the piston 15 is moved by the spring 17 to put the engine oil pressure line into communication through a reduced portion 24 of the valve 16 with the passage 25 leading to the plunger 26. The plunger 26 is thus moved against its spring 27 to move the valve 7 to its byepass position. A recess 31 is provided on the valve 16 and a drain passage 29 from beneath the piston 15 to drain off any oil which might hinder the operation and re-setting of the device.
