Abstract: 1362622 Severing PLESSEY CO Ltd 21 June 1973 [1 Aug 1972] 35825/72 Heading B3D Equipment for cutting thin slices of material, such as silicon or gallium phosphide into pieces as small as 0À125 mm. square comprises a microscope 3 adjustable relative to a cutting wheel 1 so that a hair line is in the same plane as the wheel, a work-table 2 located between the microscope and cutting wheel and having an aperture through which the wheel can be viewed by the microscope, a mounting 4 by which the workpiece 12 can be mounted between the worktable and cutting wheel and having an opening 9 which registers with the aperture so that a cutting trace on the workpiece can be viewed by the microscope, the mounting being capable of orienting movement relative to the work-table, and means 16 for clamping the mounting to the work-table. The cutting wheel is rotatable in a vertical plane beneath the horizontal worktable, the wheel and table being relatively adjustable. The microscope is mounted above the aperture in the table which receives the mounting 4 in the form of a collar 5 having an upper flange 6 resting on the table and a lower flange 8 defining the opening 9. A transparent plate 11, such as a microscope slide, is temporarily secured to the lower flange, for example, by adhesive tape, and the workpiece 12 is waxed or otherwise secured to the lower surface of the plate. In operation, the microscope is adjusted until the hairline in its eyepiece is in the plane of the cutting wheel. The workpiece is waxed to the plate and the plate is secured to the mounting which is then placed in the aperture and oriented until a cutting trace on the workpiece and visible through opening 9 is aligned with the hair line of the microscope. After securing the mounting in position by clamps 10, the workpiece is cut by the wheel 1.

Abstract: 884,866. Wrenches. SWENSON, O. J. Oct. 26, 1959 [Nov. 12, 1958], No. 36151/59. Class 61. In a ratchet wrench comprising a rotatable tool head 3, a rotor wheel 4 surrounding the head 3 and having mounted thereon pivoted pawls 15 which engage with the teeth 7 of the ratchet wheel 6 which carries the tool head 3, the ratchet and pawl members are utilised as anvil and hammer members respectively to provide magnified torque force. The impact blows are delivered from energy stored in a coiled compression spring 5 housed in the operating handle 2, the spring 5 being connected to the rotor through a pivoted link 24. The handle 2 includes two parallel mounting plates 26, 27 each have a circular hole in which are mounted the tool head 3 and shaft portions 9, of the ratchet wheel 6. Annular cams 29 are secured to the inner faces of the plates 26, 27, the inner walls 33 of the cams providing bearings for the shaft portions 9 of the tool head and the inner walls 18 of the rotor being supported on the bearing surfaces 30 of the cams. The pawls 15 normally lie in the recessed portions 32 of the cams with the leading ends 17 of the pawls contacting the impact surfaces 8 of the ratchet teeth. A stop block 34 on the inner side of each handle plate 26, 27 is engageable with a stop bar 22 on the periphery of the rotor. The tool can be used as a ratchet wrench. On further movement of the handle 2 after the fastening has become tight, the handle 2 and cams 29 advance relative to the rotor 4 and tool head 3 until the pawls 15 are cammed out of engagement with the ratchet teeth 7, the spring 5 then expands and rotates the rotor to a position where each of the pawls 15 engages the next rack tooth with considerable impact force.

A device of pistol construction suitable for spraying paint electrostatically or pneumatically comprises a cup-shaped atomizer 1 adapted to be rotated by a drive shaft 5, an impeller 6 arranged to be driven by compressed air supplied through a conduit 15 so as to rotate said shaft, and means for supplying compressed air and paint to a nozzle 7 at the end of the shaft 5 through conduits 14 and 13 respectively. During electrostatic spraying the spray head is either maintained at a high potential or a metal electrode is located in the paint feed conduit 13. Compressed air is supplied through the conduit 15 only and paint fed through the conduit 13 is diverted at right angles and flows downwardly into the rotating cup 1. The paint passes through slits 1f in a disc 1c and is atomized at an edge 1g. The device is converted to pneumatic spraying by rotating avalve 17 and the high potential may be switched off if required. The air supplied through the conduit 14 causes the paint to be discharged centrally through outlets 10 and 1d. The casing 1a of the cup 1 may be removed from its flange 1b to facilitate cleaning. Air is also discharged through an outlet 18 so as to prevent back-spray.

Title: Refractory composition
IPC: H01B1/00
Filed: 1961-10-18
Abstract: Refractory materials are prepared by heating a mixture of molybdenum disilicide and vanadium pentoxide powders to a temperature of at least 1000 DEG C.  The two powders may be present in any proportions but preferably 1 - 30% by weight of the total composition is vanadium pentoxide.  The powder mixture may be compressed to any desired shape at 10,000 pounds per square inch.

Abstract: 792,407. Pipe joints. SOC. VALLOUREC. Dec. 6, 1956, No. 37344/56. Class 99(1). In a fluid-tight coupling permitting relative angular movement of pipes 1, 2, a flared ring 9 attached to a bell mouth 2a on the end of the pipe 2 provides an annular space to receive a ball jointing member 3 fixed to the pipe 1, e.g., by welding, the joint being sealed by a rubber &c. packing 8 housed in an inwardly directed rim 7 on the bell mouth 2a and adapted to surround the end 1a of pipe 1, coupling being effected by rotating a loose collar 4 engaging the ring 9 ; as shown, hooks 5 enter notches 11 in a flange 10. Stops 6 on pipe 1 prevent removal of the collar. Coupling is effected by pushing the pipe end 1a past the rim 7 into the packing 8 which causes the inner lip 8a to yield resiliently and grip the pipe. Slight clearance α between the rim 7 and the pipe 1 avoids rupture of the lip 8a. The hooks 5 are then engaged with the notches 11 and are rotated approximately 180 degrees about rim 10 until they abut a boss (not shown).

Abstract: 811,144. Discharge tube oscillating circuits. ENGLISH ELECTRIC CO. Ltd. Dec. 30, 1955 [Dec. 31, 1954], No. 37791/54. Class 40 (6). In a phase-shift oscillator comprising resistive and capacitive elements, at least one of the elements is included in a further part of the circuit to perform an independent function. Feedback from the anode of discharge tube V takes place over capacitors C1, C2 and resistors R1, R2 to the grid of the tube. The phase-shift is completed by resistor R3 which also provides cathode bias, and capacitor C3. In order to provide the correct values of phase-shift and bias it may be necessary to return the lower end of resistor R3 to a negative potential.
