Title: Improvements in or relating to a method and apparatus for use in electrolytic machining
IPC: B23H3/00
Filed: 1962-06-19
Abstract: An apparatus for electrolytic machining of metals and "metalloids", e.g. tungsten carbide, provides for (1) moving the workpiece vertically in addition to feeding it to and from the electrode, (2) moving the electrode vertically and horizontally across the face of the workpiece in addition to feeding it to and from the workpiece. The electrode is contoured to the final shape desired, and presents a working face which widens in the direction of flow of the electrolyte towards the faster moving areas of the workpiece.  A workpiece W, Fig. 1, is mounted to be rotated at speeds up to 3000 r.p.m., and fed forward towards the electrode face 25, and is also mounted on a table 33 which may be raised or lowered.  The electrode 25 is fed with electrolyte from a tube 31, and is rotatably mounted on cross slides 2. Adjacent the electrode is mounted an insulating prod 25a which projects slightly beyond the electrode face to a predetermined extent, and as etching proceeds contacts the workpiece thus slowing down the motor and by suitable external circuitry stops the motion. In another form a contact member 5a approaches and <PICT:1004829/C6-C7/1> <PICT:1004829/C6-C7/2> meets a switch member 51 to switch off the current.  The motions may be made automatically by transducers and similar circuits, by pneumatic, or hydraulic servomechanisms. A number of contoured electrodes are illustrated, e.g. segments of sector shape 25, Fig. 14, with intermediate channels 25G through which the electrolyte flows out fan-wise, and also through slots 25B.  The exits may have a dam mounted adjacently which restricts the effect of the electrolyte to a limited area in the early stage where larger amounts of metal are to be removed, which dam is then retracted to give full flow across the workpiece.  In another form the pressure of electrolyte feed is applied to control the gap to a predetermined value (Fig. 3).  The electrode may be rocked to and fro on an axis (Fig. 8).  A series of electrodes may be used to machine long cylindrical workpieces (Figs. 6 and 7). Machining is effected at 3-20 Volts and up to 2000 Amps. per sq. inch using alkali metal chloride solutions at 50-250 lbs. p.s.i. using a gap of 0.005 inch or less.  Specifications 943,101 and 944,613 are referred to.

Abstract: 1,049,438. Doping semi-conductors. SIEMENS-SCHUCKERTWERKE A.G. June 4, 1965 [June 20, 1964], No. 24056/65. Heading H1K. Dopants or other foreign substances are diffused into a monocrystalline semi-conductor body by sealing the body and two separate sources of the foreign substances in an ampoule and heating, after which the interior of the ampoule is divided into two by fusion so that the body and one of the sources are contained in one part of the ampoule which is further heated. A quartz tube 2 contains silicon discs 3, quartz support rings 4 and 5, quartz tube sections 8 and 10, an aluminium source 6 comprising a silicon disc with a drop of aluminium alloyed thereto and a gallium source 7 also comprising Ga on a silicon disc. The ampoule 2 is degassed under vacuum at 1000‹ C. prior to sealing off at 9. The sealed ampoule is heated to diffuse Ga and Al into the Si discs and then the tube surrounding tube section 10 is sealed off and further heated to diffuse in Al. In another embodiment, another tube section like 10 is included so that the Al source may also be sealed off from the discs, thus enabling the discs to be subject to heat treatment only. A method of cleaning the quartz pieces prior to use is described. It is stated that rectifiers, transistors or photo-semi-conductor devices may be constructed using the invention. A mode of making a PNPN thyristor is briefly described.

Title: Articulated toy figure
IPC: A63H3/00
Filed: 1976-06-10
Abstract: 1492017 Toy figures GENERAL MILLS FUN GROUP INC 10 June 1976 [11 June 1975] 24107/76 Heading A6S [Also in Divi sion F2]  A toy figure having an arm movable at its shoulder joint relatively to its torso includes gearing within the torso which can impart step-by-step movement to the arm, the gearing being engageable to transmit the step-by-step movement and disengageable to allow free movement of the arm. As shown, inward depression of a plunger 172, Figs. 5, 8, extruding; out of the back of the toy figure, against spring biass acts through a post 166, Fig. 8, to turn a ratchet wheel 162 about a vertical shaft 144. The ratchet wheel 162 is spring biassed to engage a second ratchet wheel 155 fast on the shaft 144, which also carries a worm 160. The worm 160 can either be engaged with a worm wheel 196, Fig. 5, or by tilting the shaft 144 rearwards of the toy figure, Fig. 9, disengaged from the worm wheel 196. Engagement and disengagement of the worm and worm wheel 160, 196 is effected by turning the head 34 of the doll to the right and to the left, respectively, to act through a cam step (260), Fig. 10 (not shown) on a lever 270, &c. Fig. 8, journalled on a pin 134 and having its end 268 receiving the top end 154 of the shaft 144. A slot 138 receives the top end 154 of the shaft: turning the head 34 slides the shaft end 154 from one end to the other of the slot 138. The lower end of the shaft 144 is carried in a ball 148 (see also Figs. 5, 9) supported within a recess in a casing member, so as to allow the shaft 144 both to rotate on its own axis and also tilt forwards and backwards within the torso of the figure. With the worm and worm wheel 160, 196 engaged, rotation of the latter is transmitted to a gear 202, Fig. 8, meshing a gear 214 forming a part of an overload release ratchet clutch 215 driving a shaft 228 and a coupling 220 (see also Fig. 3) connected to the right arm 26 of the doll. If an undue stress is applied to the arm while the worm and worm wheel 160, 196 are engaged, the overload release clutch 215 battles over to prevent damage to the gearing. With the worm and worm wheel 160, 196 disengaged, the arm 26 may be freely pivoted down from a raised position to which it has been moved by repeated actuation of the plunger 172. Alternatively, the left arm 28 of the doll may be raised by similar gearing. In a modification, the lever 270, &c., Fig. 8, controlling the disengagement, &c. of the worm and worm wheel 160, 196, is replaced by a slotted and grooved plate (316), Figs. 12..14 (not shown), pivoted upon a stud (306) and engaged by a pin (334) depending from the doll's head (330). Manually movable swivel joints are provided at the elbows (90), Fig. 2 (not shown), hips (50), (52), Fig. 4 (not shown); knees, wrists, &c. of the toy figure. The structure of the figure is enclosed in a resilient skin, which helps to retain inserts, e.g. simulated batteries (77, 79), Fig. 1 (not shown), in recesses in its arms.

Abstract: 953,348. Fuel injection systems. CONTINENTAL MOTORS CORPORATION. July 13, 1960, No. 24457/60. Headings F1A and F1B. Lubricating oil is added automatically to the fuel to promote ignition at low loads and speeds, the addition being controlled by means responsive to the residual fuel pressure in the fuel injection lines. In Fig. 1 a check valve 17 in a connection between the delivery pipes of the lubricating oil pump 16 and the fuel injection pump 14 opens at low loads and speeds when the reduced fuel pressure in the fuel delivery pipe drops below the oil pressure. The fuel injection pump, Fig. 2, has a conventional piston-type delivery valve 50 to reduce the pressure in the space 23, connected to the delivery passages 24 through a distributor groove 60 on the rotating and reciprocating piston 25, immediately the pump stroke ceases to prevent drip from the nozzles. The lubricating oil system is connected to the space 23 through a connection 63 containing the check valve 17. During normal running conditions the residual pressure in space 23 and the injector lines is greater than the oil pressure and the valve 17 is held closed; at low speeds and loads the residual pressure drops below the oil pressure and check valve 17 opens between injections to admit oil to the fuel.

Filed: 1927-09-19
Abstract: 277,697. Seailles, J. C. Sept. 18, 1926, [Convention date]. Alkaline earth and sodium aluminates, alumina.-A hydrated alkaline earth aluminate is prepared by treating a mixture of pulverised non- halogenated ore of aluminium with an alkaline earth base in the presence of hot or cold water under normal pressure or in a digester, and is converted to sodium aluminate by the addition of sodium carbonate or sulphate. Alumina is prepared from the sodium aluminate by a known process, e.g. precipitation by carbon dioxide. If the alkaline earth aluminate is soluble e.g. barium aluminate, it is filtered and the barium precipitated directly by a hot or cold solution of sodium carbonate or sulphate; or it may be first precipitated by lime as calcium aluminate and then so treated, that barium hydroxide is recovered. If the ore contains combined alumina, it is first calcined. The barium, calcium, magnesium or strontium hydroxide is present preferably in from one to two molecular proportions to the alumina.

Means for holding an article comprises a disc 10 of resilient cellular material which is formed with an aperture extending from one face of the disc towards the other face, said aperture being shaped to receive the article to be held and the disc being of such thickness that when the article to be held is inserted in the aperture the wall bounding the aperture, which is deformed during such insertion, operates to grip the article resiliently, the disc being so constructed that when the article is inserted in the aperture the disc and article together form a suction cap whereby the disc and article are, when moved into engagement with a planar supporting surface, held suctionally in such engagement. As described the aperture in the disc is of tapered form and the disc is made of synthetic rubber or elastomeric plastics material. The aperture either extends completely through the disc or the disc has a membrane which closes the end of the aperture which opens onto the lower face of the disc: this arrangement prevents chattering of a bottle on, for example, a polished wooden surface.

Abstract: 1,067,123. Pure fluid amplifier. R.E. BOWLES. June 16, 1964 [June 17, 1963], No. 24813/64. Heading G3H. A pure fluid system comprises an amplifier 13 having a power jet 14 and control nozzles 15, 16 leading to an interaction chamber. The chamber comprises an end wall 24 and diverging side walls 25, 26. A flow divider 27 has surfaces 30, 31 forming passages 47, 48 with the side walls. Lateral ducts 41, 42 diverge from the passages and downstream sections 25a, 26a of the side walls are offset to increase the crosssectional area of the passages. When a control jet is applied through nozzle 15, the flow follows the direction of the arrows and the jet locks on at points B and D. A vortex V induces flow from passage 47 and flow is induced from duct 41. When the passage 48 is partially blocked by member 50, a vortex is formed at the entrance of duct 41 which may preclude flow from the duct, to the passage, and a vortex is formed at the outlet of passage 48. When the passage 48 is completely blocked, e.g., when passages 47, 48 are connected to the opposite ends of a piston cylinder device, flow takes place from the passage 48 to the duct 41.
