Title: Improvements in or relating to casement stays
IPC: E05C17/30
Filed: 1946-06-19
Abstract: 613,378. Stays for hinged articles; stud-andsocket fastenings. BERG, A. L. June 19, 1946, No. 18451. [Classes 44, 65 (i) and 65 (ii)] A stay of the kind in which a rod 4 telescopes within a sleeve 3 and carries friction-shoes 7 adapted to co-operate by means of wedge surfaces and to exert a pressure on the walls of the sleeve when pressed together in the axial direction of the rod, is characterised in that the axial pressure is effected by springs 8 and 9 bearing on the two extreme shoes, so that all the shoes will be displaced axially when the spring pressure is changed. The rod is pivoted to a window and the sleeve, which is square in cross-section, is pivoted releasably to a pin 5 secured to the frame. A spring- loaded push-button 15, adapted to engage with a circumferential groove 18 in the pin, when displaced inwardly enables the sleeve to be lifted off the pin. Rotation of the freed sleeve in either direction causes a square nut 13 to move along the rod, thus increasing or diminishing the spring pressure.

Title: Improvements in fluid pressure actuated portable drilling machines and the like
IPC: F03C1/36
Filed: 1928-06-27
Abstract: 319,711. Keay, R. W. June 27, 1928. Engines with main shaft parallel to axis of cylinder; driving-gear. - A portable drilling- machine having a fluid-pressure actuated engine of the swash-plate type has a ring of gear teeth on the swash-plate which roll round a bevel gear on the drill-spindle to rotate it at a lower speed. A crank-shaft is also rotated by the swash-plate and serves to drive a rotary valve for controlling admission of fluid to the cylinders. A cylindrical casting 1 has four parallel bores 2 forming the cylinders for pistons 7 connected by ball-ended rods 9 to the swash-plates 11. Rotation of the swash-plate is prevented by blocks 15, Fig. 3, attached by screws 14 to the swash-plate and sliding in arcuate guides 16 carried by covers 17 inserted into diametrically opposite slots in the casing 1. A ring of gear teeth 12, Fig. 1, on the swash-plate rolls on a bevel gear 18 attached to the drill-spindle 19 and rotates the drill at one sixth of the speed of its own oscillation, but this velocity ratio may be modified and additional gearing may be provided for giving a wider range of velocity ratios. The drill-spindle is rotatably secured in the cover 22 of the casing 1 by a gland 26, a metal ring 25, a thrust collar 23 and a ball bearing 24. A single throw crank shaft 13 is rotatably mounted in the swash plate and also at 28 and 29 in the drill-spindle and a central boss 3 of the casing 1 respectively. The upper end of the crank shaft carries a key 30 lying in a semicircular recess in a valve 5 rotatably mounted in a liner 4. A knurled flange 42 on the valve allows the latter to be rotated by hand relatively to the crank-shaft and cause the key 30 to engage one end or the other of the semi-circular recess and thus determine the direction of rotation of the engine. Motive fluid is admitted from one side of the casing 1, through a port in the liner 4, to an annular recess 36 in the valve and thence by a port 37, Fig. 4, and ports in the liner to each cylinder in turn. Exhaust takes place from ports 39, 38 in the cylinders and liner and a recess 40 in the valve, to atmosphere.

Filed: 1958-06-13
Abstract: 858,367. Electrical measuring systems. IMPERIAL CHEMICAL INDUSTRIES Ltd., and CROWCROFT, P. L. May 7, 1959 [June 13, 1958], No. 18951/58. Class 40 (1). [Also in Group XL (c)] Apparatus for measuring pressure comprises a differential inductance transducer controlling the frequency of two oscillators, the difference frequency being linearly related to the change in pressure. As shown (Figs. 1, 2), the transducer comprises an elliptical pressure tube 5 carrying rods 7, 21 attached to diaphragms 9, 23 on which are mounted one half of an E and I core having two similar coils 18, 19 and 32, 33 wound on the E core, the other half of each E and I core being fixed to the housing. The arrangement is such that an increase in pressure inside tube 5 causes the pin 7 to decrease the air gap between the E and I core pair 16, 15 whilst the pin 21 increases the air gap between the other E and I core pair 30, 29 by an equal amount. Each pair of coils determines the frequency of an oscillator valve 37, 38 (Fig. 3), the oscillator outputs, at the same frequency at atmospheric pressure inside tube 5, being mixed in valve 43, and the beat frequency being fed to a meter. When the pressure inside tube 5 is increased, the oscillator frequencies vary linearly with pressure in opposite directions to give a beat frequency output proportional to the change in pressure. The temperature coefficients of rods 7, 21 are matched to compensate for variations in ambient temperature.

Title: Improvements in and relating to electrical generating systems
IPC: H02P9/00
Filed: 1946-06-26
Abstract: 654,928. Hot gas engines. NAAMLOOZE VENNOOTSCHAP PHILIPS GLOEILAMPENFABRIEKEN. June 26, 1946, No. 19071. Convention date, April 27. 1942. [Class 7(i)] [Also in Groups XXVI and XXXV] In a unit comprising a closed-cycle hotgas engine driving an A.C. or D.C. electric generator the voltage at a load point is maintained constant with varying load by means of a governor which operates to regulate the average pressure of the working medium of the engine in one working cycle. An air compressor 14 mounted on the engine 10 feeds compressed air through a pipe 15 into the crank case 27, the interior of the crank case being in communication with the working spaces. of the engine by way of cyclically opening valves in the cylinder walls. The interior of the crank case is also in communication with the interior of the hollow end portion of the crank shaft 11 which has an end closure 16 provided with a slidable exhaust valve 17 in the form of a hollow cylinder with closed ends and with apertures 18, 19 in the periphery near the inner and outer ends respectively. The aperture 18 is of triangular form and located so that it is wholly within the end wall 16 of the crank shaft when the valve is in its outer position, and provides communication between the interior of the shaft and the external aperture 19 when the valve is in its inner position. The sliding movement of the valve 17 is controlled by a centrifugal governor comprising a pair of weights 24 pivoted in lugs 21 on a disc or flywheel 22' on the crank-shaft 11, the outward movement of the weights, against the action of tensioned springs 25, producing inward movement of a member 23 which pushes the valve inwardly. Increased load on the generator 13 produces momentarily reduction in engine speed whereupon the weights 24 move inwardly, allowing the valve 17 to be moved outwardly by the internal pressure in the shaft 11, so that the aperture 18 is closed. The pressure: within the crank-case is increased by the independently operated compressor 14, and the engine power increases. The slide valve 17 is so constructed in relation to the voltage-load curve of the generator that the increased engine speed is such that the generator voltage is maintained at a predetermined value with increased load. In a modification, Fig. 3, the pressure within the crank-case is regulated by a balanced valve 26, 26a of the poppet type operated electromagnetically in dependence on the voltage at a point at which constant voltage is required, an iron core 31 being secured on the valve stem 28 and within a solenoid coil 30. The core and coil are located within a cylindrical housing 29 of soft iron which is apertured axially to permit longitudnial movement of the valve stem against the action of a compression spring 32. The balanced valve 26 may be replaced by a small ball valve.

Abstract: 871,739. Electromagnets. LEDEX Inc. June 18, 1957 [Aug. 28, 1956], No. 19164/57. Class 35. [Also in Group XXIV] A device for translating axial motion of a driving element such as the armature of an electromagnet, into rotary motion comprises two parallel annular plates separated by at least one rolling member in arcuate recesses in the plates concentric with the driving-shaft, one plate being connected to the shaft through a clutch member which frictionally engages the movable recessed plate on axial movement of the driving element. As shown, movement of the armature 42 with its disc 44 towards the fixed core 16 also moves the ring 54 producing angular movement of the latter against springs 58 due to the pressure on three balls 64 in recesses on ring 54 and the part 52 of the electromagnet core. The axial pressure causes ring 54 to impart rotary movement to the armature disc 44 and hence to the disc 50 on the shaft 30 coupled to disc 44 by a pin-and-slot connection. The parts may be duplicated " back to back " with the rings or discs at the outer ends or there may be a common armature between duplicated sets of discs and electromagnet field members, in each case the shaft being movable at will in either direction according to which coil is energized. Reference has been directed by the Comptroller to Specification 602,812.

The plates are alternately locked by a pin 32 having grooves 33, 34 selectively registrable with the plates for releasing them, the full diameter portion of the pin engaging recesses in the plates to lock them in position. The gear-change pin 23 is engageable in grooves in gear control rods 40-42 which may either preselet or establish a ratio. As shown, plate 16 is locked, and on moving pin 23 to the left it is guided along slot 20, and initially brings control rod 41 to its neutral position and then disengages the groove in this rod and engages the groove in rod 42, the movement finally moving rod 42 to an engaged position. Pin 23 also moves plate 17 to a new position. For the next gear change plate 17 is locked, plate 16 freed, and pin 23 moved from left to right. Changes are made sequentially, in the order reverse, first to fourth, or in the reverse order. The plate 17 is provided with wedge-shaped blocks 46 which enter the grooves in the control rods 40-42 when in their neutral positions in order to retain them in position. Locking pin 32 may be solenoid actuated and gear change pin 23 may be actuated by an electric or pneumatic motor. Specifications 841,983 and 841,984 are referred to.

In a hybrid isolation technique for an integrated circuit in which regions of one conductivity type extending from a high resistivity substrate of the second conductivity type are laterally separated by dielectric material, highly doped regions of the second conductivity type are provided in the substrate beneath the dielectric material to prevent the formation of inversion layers. The surface of a high resistivity P-type silicon wafer (1) doped with boron is oxidized to form a mask (7) and boron is diffused-in to produce P<SP>+</SP>-type regions (9). The oxide layer (7) is removed and a new oxide layer (10) is grown over the diffused regions (9). The wafer is then heated in a stream of silicon tetrachloride and hydrogen doped with arsine to grow an epitaxial N-type layer (12) on the exposed parts of the substrate. An N<SP>+</SP>-type layer 11 may be produced adjacent the surface of the substrate (1) either by varying the concentration of dopant during deposition or by diffusing N-type impurities into the exposed surface of substrate (1) before depositing layer (12). The wafer is then heated in a stream of silicon tetrachloride, carbon dioxide and hydrogen to deposit a layer (13) of silicon dioxide on the surface to fill the channels between the epitaxial regions. The part of the oxide layer (13) covering the epitaxial regions is removed by etching or abrading. As shown, Fig. 6, a transistor is produced in region 12 by diffusions of boron and phosphorus or arsenic using an oxide mask 17. The collector region is provided with a high conductivity path extending from N<SP>+</SP>-type layer 11 to the surface. Other dielectric materials such as silicon monoxide or aluminium oxide may be used and may comprise partly silicon dioxide and partly polycrystalline silicon.
