IPC: H01L21/00
Filed: 1968-09-11
Abstract: 1,178,210. Semi-conductor devices. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd, 11 Sept., 1968, No. 43131/68. Heading H1K. A ceramic rectifier comprises a semi-conductor titanate plate having a non-ohmic electrode on one face and an ohmic electrode on the other face, the non-ohmic electrode comprising 68-92À8 wt. per cent silver and 7À2 to 32 wt. per cent of a combination of lead oxide and bismuth oxide in a mol. ratio of 0À5 to 1À5. As shown, Fig. 1, a body 1 of barium titanate is provided with a rectifying contact by painting-on a paste comprising silver containing lead oxide and bismuth oxide in an organic binder, such as a polyester, and firing at 600- 900‹ C. in air. A layer 4 of silver oxide underlying a layer 2 of silver is produced by this method and it is stated that the silver oxide is a P-type semi-conductor while the barium titanate is an N-type semi-conductor so that a PN heterojunction is formed. An ohmic contact is applied to the opposite face of the body 1 by depositing a layer 3 of aluminum and a layer 4 of copper by evaporation. The barium titanate 1 may also contain as additives silver oxide, aluminium oxide, silicon oxide, and excess titanium oxide, and may be produced by mixing titanium oxide and barium carbonate, pressing to shape, and sintering. The pellets may be calcined before sintering.

The free trolleys may be joined to consist of a lead trolley 14 and one or more trailing trolleys 14a, nested trolleys leaving a gap "e" between projection 64 of the front trolley and a recess 63 at the forward end of the rear trolley, the projections and recesses being formed in plates 50 forming the bodies of the trolleys. When trolleys abut, the front lug 40 is moved out of the path of the conveyer by engagement of a curved surface thereon with face 67 of the forward trolley and the drive to the rear trolley is lost. The connecting member will engage the front trolley of a line since lug 40 will be free to move into the conveyer path and lug 41 engage in gap "e", the distance between the lugs being greater than the length "g" of the upper part of the free trolley. To stop free trolleys at a station a bar 71 may be moved into the path of the connecting members to disconnect them from their trolleys, the length of the bar being greater than the distance between the lugs of said members.

Abstract: 1,069,719. Valves. ECLIPSE FUEL ENGINEERING CO. Oct. 30, 1964, No. 44426/64. Heading F2V. In a manually resettable automatic shut-off valve e.g. for terminating the supply of fuel to a gas- or oil-fired boiler, operable upon failure of an associated electrical circuit, closure 26 upon stem 28 is held in the open position, against spring 64, by a yoke 100 which is locked in position by the over-centre engagement of a pin 114 and slot 112 connection to a crank arm 116 operated by handle 224 and to which knock out arms 122 are pivoted whereby shoulders thereupon engage under rollers 154 fixedly supported by the stem 28. The arms 122 are each urged to the engaged position by a torsion spring 140, connected at one end to an upstanding arm 142 of member 100 and are operatively engaged with rollers 154 in slight over-centre position permitted by contact of a cross arm 128 therewith. Upon failure of an associated electrical circuit a solenoid is de-energized permitting displacement of a plunger (174) (Fig. 7, not shown) by a coil spring (194) and the engagement of the arms of a U-shaped impact head (124) thereof with extensions (130) of the knock-out arms (122) which are pivoted out of engagement with the rollers (154) to permit closure of the valve. An upstanding arm (142) of the yoke acts as a stop for the U- shaped head until lowered with the yoke (100), upon rotation of the handle (224), for re-engagement of arms (122) under the rollers (154), and the plunger (174) thereafter obstructs the return of the upstanding arm (142), and hence the yoke (100) and re-opening of the valve, until the solenoid is re-energized by the electrical circuit.

Title: Hobbing Machine

Filed: 1966-10-07
Abstract: 1,167,353. Gear-cutting. TEXTRON Inc. 7 Oct., 1966 [18 Oct., 1965], No. 44957/66. Headings B3B and B3K. A hob head comprises drive means 36, Fig. 3, for rotating the hob arbor 45 and a second drive means 86 for rotating an axially-fast hob shifting member 62. The work slide 15, Fig. 1, carries a chuck and a tailstock 17 moved on circular guides 21 by a screw 22. The hob is rotated by a motor 26 through belt gearing 27, a shaft 24 and gears 25, 39, 40, 42. The gear 42 carries a flywheel 43. A gear 53 driven by the flywheel 43 rotates a pinion 56 which can be clutched to a pinion 57 by a hand lever or by an hydraulic device 58 when the motor 86 is operated. The pinion 57 drives a gear 60 continuously to rotate the hobshifting nut 62. The tooth numbers are chosen to cause the nut to produce axial movement of the hob. The overall limits of movement are determined by a plate 74 abutting the ends of a sleeve 72 to cause movement of a plate 78, a ring 75 and switch-actuating plungers (80, 81), Fig. 4 (not shown). The gear 60 can also be advanced intermittently by a reversible hydraulic motor 86 through a hydraulic clutch 87 and gears 85, 84. The motor may be operated at timed intervals or after a set number of machined workpieces has been registered by a counter (140) so that the hob is adjusted intermittently instead of continuously. The counter is actuated by operation of the chuck, by the number of movements of the work-, or hob-, slide, or the number of revolutions of the work. It may be automatically reset. When the limit of movement of the hob arbor has been reached, the arbor is rapidly returned ready for further advances. A lamp is lit at either end of travel of the arbor. The increments of movement of the hob arbor for intermittent shifting are set by a dial 104 carrying a switch-operating pin (105). The dial is advanced with the nut 62 by operating a piston 89 which clutches the parts together. Both intermittent and continuous shifting movement may be used and the intermittent movement may add to, or subtract from, the continuous movement. By fitting suitable gears 53, 56, 57, 60, intermittent movement only may be obtained.

A concave elastomeric diaphragmatic transverse wall 50 closes the spout and comprises a peripheral flange A forming a seal with the internal wall of the spout A. A discharge opening E is formed in the spout on the opposite side of the transverse wall to the flange 42 while a protuberance B on the transverse wall permits the distortion thereof along with the peripheral flange A to permit fluid discharge through the outlet E. At least one and preferably two gussets 52, 53 may exextend between the internal face of the transverse wall adjacent the position of the protrusion B and the peripheral flange A adjacent the outlet E. The second gusset 53, if provided, is preferably diametrically opposed to the gusset 52. In the embodiment of Figs. 5 to 7 (not shown) the face of the peripheral flange in contact with the internal surface of the spout is stepped to provide an improved seal. In the embodiment of Figs. 12 and 13 a protrusion 328 and rib portion 331 are provided on the opposite surfaces of the transverse wall 319 adjacent the discharge opening 324 in the spout. Such an arrangement permits deformation of the wall 319 and peripheral flange 322 as shown in broken lines in Fig. 12 when finger pressure is applied to the protrusion 328.

The fluid may be gas or liquid, e.g. air, carbon dioxide, nitrogen or steam. One or more chambers may be used and tubes 13, 14 need not have the same diameter and may be of variable diameter. Alternatively, Fig. 2B, the vortex may be formed in tube 25 by fluid fed from chamber 22 in which a vortex is also generated. For cooling, chamber 22 may be surrounded by a water jacket. In examples, two devices as in Fig. 2B are used to heat and cool yarn in a simultaneous draw-false twist process using a friction bush. The heating and cooling of polyester and polyamide yarns is exemplified.

In Fig. 2 the arcuate stator 2 carries three bearing rollers 5 engaging the roller 1, the bearing rollers either being mounted on spindles 6 supported by the stator core or running directly in grooves in the core. In a modification a plastics coating enables the stator periphery to engage the roller 1 directly. In Fig, 3, where the stator extends over less than 180 degrees, bearing rollers 5 are carried by end-plates 7 attached to the stator. The stator is restrained against rotational and axial movement by bars engaging recesses, by wires, or by rods engaging ears (Figs. 5-7, not shown).
