Abstract: 1,051,246. Piezo-electric elements. I. G. VASIN, and P. G. POZDNJAKOV. Oct. 16, 1963, No. 40805/63. Heading H1E. A torsional resonator comprises a bar 1 of quartz having an approximately square crosssection and cut such that the longitudinal edges lie in the direction of the X-axis and the end edges form angles of +40‹ and +50‹ with the Y- and Z-axes. Such a bar will execute torsional vibrations if four electrodes of alternate polarity are applied to the major faces. It is stated that the bar, if cut square, operates at a stationary point on the temperature/frequency curve within a temperature range of 15-20‹ C. and that, if the width to thickness ratio is changed within the range from 1À2 to 0À85, the stationary point can be altered within the range from - 30‹ to + 100‹ C. Fundamental (25 - 130 kc/s.) or overtone operation may be used.

Abstract: 1,053,274. Valves. OWATONNA TOOL CO. March 9, 1965 [April 22, 1964], No.10011/65. Heading F2V. Fluid flowing into an inlet port 18 divides into two streams each flowing through one of the orifices 27, 28 into a corresponding passage 32 or 33; the size of each orifice depends upon the desired ratio of flow between the two streams. Passage 32 has a chamfered valve-seat 52 discharging into an outlet port 20 that may be connected to tank. The other passage 33 leads to a further outlet port, the pressure in which acts on a sliding closure member 54 having an enlarged head 55 which co-operates with the seat 52. The inner diameter of the seat and outer diameter of the piston portion of the valve are equal to provide balancing; the latter is grooved and fluid from passage 33 has access to the periphery thereof through bores 60, 64. An additional port common to the port 20 is provided to receive the fluid returning from the user apparatus connected to the further outlet port, the flow resistance of which apparatus determines the pressure in passage 33 and hence the position of the member 54 relative to the seat 52 which in turn controls the pressure at the outlet port 20. The passages 32, 33 are formed in removable casing portions 13, 14 which provide access to the valve and orifice and plugged inspection holes 35, 36 are included in the portions 13, 14.

Abstract: 1,231,338. Laminated magnetic memory element. THOMAS & BETTS CORP. 11 April, 1969 [23 April, 1968], No. 18733/69. Heading B5N. [Also in Division H3] A woven memory has a web of insulated copper conductors 11 woven around straight tunnels into which are removably inserted wires 16, Fig. 3, having a thin magnetic film electroplated thereon, the web being laminated between sheets of insulating material 40. The tunnels are formed by weaving conductors 11 around steel wires 10, which are subsequently removed. The conductors 11 also pass round a steel bar 9 which is removed after lamination so that the conductors may be cut at 8 for connection to signal sources. After weaving, the web 13 is placed between two pliable, deformable sheets of insulating material 14, 15, stored on drums 18, 19, and passed between rollers 16 and 17, the latter preferably being rubber sheathed and the former heated, so that lamination by pressure and/or heat is effected. The laminate is then cooled, e.g. by water at 21, cut to the desired size and wires 10 removed at 22. Insertion of the electroplated wires completes the memory, the wire size being chosen to provide a tight, non-stressed connection.

Abstract: 1,232,034. Blasting. PENNSALT CHEMICALS CORP. 30 July, 1968 [21 Aug., 1967], No. 36333/68. Heading B3D. A blasting device, particularly for trimming thick-film resistors, comprises means supplying pressurized gas and abrasive particles to a nozzle by a single conduit, exhaust means for removing used abrasive particles and a by-pass connecting the conduit and exhaust. It is thus possible to cease supply of particles to the nozzle to facilitate changing the workpiece by opening the by-pass. A thick-film resistor or other workpiece 10 is trimmed by an abrasive stream issuing from a nozzle 12 supplied through a conduit 14 by a mixing chamber 16 where pressurized air at about 40-80 p.s.i. from a compressor 18 is mixed with abrasive powder from a reservoir 20; a vibrator 22 produces a trickle of about 3-5 gms. per minute of powder, e.g. aluminium oxide with an average particle size of 27 microns. A solenoid operated pinch valve 24 is provided in the upstream end of the conduit 14. At least the end portion of the conduit 14 adjacent the nozzle 12 is of rigid tubular construction to serve as a nozzle holder 26 journalled in an arm 30 traversed by mechanism 28 to move the abrasive stream along the length of the workpiece. The mechanism 28 is controlled by control means 36 to move a certain distance first in one direction and then on completion of abrading in the opposite direction; the means 36 also effects closing of the valve on completion of abrading. A stationary hood 44 is connected by a duct 42 to a suction device 40. The upper portion of the hood is apertured to receive the nozzle holder 26 and associated portion of the arm 30 to permit the traverse; a sealing device 46 is provided. The lower end of the hood is flared, and the hood is moulded from transparent plastic. The supply conduit 14 and the exhaust duct 42 are connected by by-pass conduits 60, 62 provided with normally closed, solenoid-operated valves 64, 66. On completion of abrading, the means 36 effects opening of the valves, thus diverting the abrasive stream from the nozzle 12 to the suction device 40 so as to keep the conduit 14 clear of deposited abrasive material between abrading operations. The means 36 may also control the vibrator 22.

Apparatus for dressing the surface of a grinding wheel 30 comprises an element 10, such as a diamond, mounted on one end of a shank 12 releasably fixed within a sleeve 14 to permit axial sliding movement of the shank relative to the sleeve, a collar 16 through which the sleeve extends and to which it is coupled to permit incremental advance of the sleeve relative to the collar, the collar being transversely mounted on one end of a manually-operable push rod 20 longitudinally slidable in guide means 24 arranged for mounting adjacent a grinding wheel. The shank 12 is releasably secured to the sleeve 14 by a thumb screw 15, and the sleeve is coupled to the collar 16 by a screw thread 18. The collar is secured to the push rod which is slidable in guide bushings, provided with elastomeric rings to prevent the entry of dirt, in the guide 24 mounted on a bracket 35 extending from a base plate which may be secured by a clamp 40 or screws to the tool rest 32 for the grinding wheel. The base plate is formed with a pair of guide rails 36, 37. In use, when the periphery of the wheel is being dressed by traversing of the diamond across the wheel by movement of the push rod, the shank 12 bears against the surface of the guide rail 36. When the apparatus is turned through 90 degrees for dressing the sides of the wheel, the shank bears against one rail during dressing of one side of the wheel and the other rail during dressing of the other side.
