Abstract: 695,385. Valves. CAMERON IRON WORKS, Inc. Nov. 15, 1950 [Dec. 3, 1949; Dec. 30, 1949], No. 27921/50. Class 135 A tapered plug valve comprises a plug member 15, Fig. 1, engaging a liner 11 in a housing 6 and supported by stems 16, 16a, the stem 16 being connected by a yoke 25, Fig. 4, to a crank 23 on a shaft 21, whereby rotation of the shaft through 180 degrees causes slight axial movement to ease the plug 15 from the liner, then rotary movement of the plug through 90 degrees, and finally an axial movement of the plug 15 to jam it in the liner. The rotational axes of the stem, the shaft 21 and the yoke tongue 24 all meet at a common point 26a, but the rotational axis of the yoke on the stem is eccentric of this point to cause the said axial movements. In another arrangement, the stem 122, Fig. 6, carries a member 136 having a horizontal slot 141 extending into a vertical slot 145, Fig. 10, and a recess 145a. The actuating shaft 129 has an eccentric pin 138 engaging the slot 141 and an angular crank 142 engageable with the slot 145. To move the plug member 116 from, say, open to closed position, the shaft is rotated through 270 degrees. During the first 45 degrees, pin 138 causes freeing of the member 116 while crank 142 moves in recess 145a and does not rotate the member. For the next 180 degrees, crank 142 engages slot 145 and turns the plug through 90 degrees and during the final 45 degrees, the crank 142 moves in the recess 145a while the pin 138 causes jamming of the plug member against the liner.

Abstract: 1,213,598. Core drills. BROWN BOVERI & CO. Ltd. 3 June, 1969 [5 June, 1968], No. 27924/69. Addition to 1,201,585. Heading B3C.  A core drill comprises a hollow shaft 3, hard metal cutter blades 35-38, secured in recesses 15-18, by clamps 20, 25, and arranged at different radial distances from the drill axis, and radially inwardly directed projections 91- 94 which will intercept uncut metal of the core 11 if the inside of a cutting edge of one of the blades is fractured, so that the drill is not damaged. External projections 98-101 are also provided, which protect the drill if the outside of a cutting edge is fractured. The drill is guided on the core 11 by studs 104-107 which are adjustably screwed into the hollow shaft 3 of the drill. In operation, if a cutter blade fractures, projections 91-94, or 98-101 abut the uncut portion of the workpiece and provide a sudden load increase on the drill, which increase causes a thermal trigger to switch off the drive motor of the machine. Oil under pressure in pockets 82 provides a hydrostatic cushion for the drill.

Abstract: 390,811. Multiplex code telegraphy. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Burton, E. T. ; 97, Cypress Street, Mill burn, New Jersey, U.S.A.) Oct. 8, 1931. No. 27943. Convention date, Oct. 8, 1930. [Class 40 (iii).] In an electrical signalling system a distributing device, adapted for repeating the impulses received from an incoming line circuit to an outgoing line circuit, comprises a rotary distributer having a plurality of groups of interconnected and rotating segments cooperating with a number of stationary contact elements wherein impulse storing condensers are respectively connected to the several groups of segments. One stationary element is arranged to apply impulses received from the incoming line to the storing condensers, another stationary element to repeat the stored impulses to the outgoing line circuit and a third stationary element to discharge the condensers after said repetition and before the application of other subsequent impulses from the incoming line circuit to said condensers. The signal impulses set up on transmitters 11, 12, 13 at a station A are transmitted in interleaved relation by a distributor 15 over a line 16 to an amplifying device 17 at a repeating station, B. The repeating device includes stationary brushes 27, 28, 29 co-operating with a rotating commutator having segments arranged in three groups respectively connected to one plate of each of three condensers 21, 22, 23 of which the other plates are connected to a common slip ring 24 and a brush 25 to earth, 26. The segments 18, 20, condensers 21, 22, 23 and slip ring 24 with the brush 25, are rotated as a whole, and in synchronism with the brush of the distributer 15. In operation an impulse is applied over brush 27 to one of the condensers-for example, the condenser 21 as shown in the drawing-whilst brush 28 serves to apply the previous impulse stored in condenser 22 to the valve repeating arrangement 30, and brush 29 effects the complete discharge of the condenser 23 in readiness for the next impulse coming in over the line 19. As the commutator rotates, the charge on the condenser 21 is applied over the brush 28 to the grid of the valve 33 and an impulse from the line is stored on condenser 23, the condenser 22 being discharged. On the further rotation of the commutator, the segment connected to the condenser 21 engages the third stationary brush 29 connecting the two plates of the condenser to earth and effecting its discharge, whilst the condensers 22, 23 are connected to the line 19 and to the grid of the valve 33, respectively. The valve repeating device 30 includes a compensating valve 34 whose plate and grid are connected respectively to the grid and plate of the valve 33. Resistances 36, 37 of a high value are incorporated to prevent the signalling charge on any of the condensers 21, 22, 23 from discharging at the time when a signal is being repeated to the cable 32.

Abstract: 1385590 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 15 June 1972 [22 June 1971] 27957/72 Heading H1K A bi-stable memory element consists of a PNP or NPN bipolar transistor structure made of one semi-conductor and another semi-conductor forming a heterojunction with one of the outer zones of the structure. The heterojunction is switchable between two stable resistance conditions and remembers the resistance condition it is in when switched off. The described embodiment comprises a silica-passivated diffused lateral transistor formed in an N-type silicon or germanium wafer with a deposited N-type gallium phosphide layer 0À1-2 Á thick contacting the emitter (or collector) zone through a hole in the passivation. The density of stacking faults dislocations and energy traps in the layer exceeds that of donor impurity atoms to give the heterojunction its bi-stable characteristic. This is achieved by depositing it by a transport reaction in a hydrogen-hydrogen chloride mixture using a doped gallium phosphide source or separate sources of phosphide. and dopant. Prior to deposition the surface is cleaned by heating in hydrogen. Electrodes of tin or indium, tin or gold-tin alloy are provided on the P-type collector zone and phosphide layer respectively by deposition and photolithographic processes. The gallium phosphide which would be P-type were the emitter N-type may be replaced by other specified AIIIBV or AIIBVI compounds or by bi-stable switching materials such as niobium pentoxide, amorphous silicon and certain semi-conductor glasses. In the characteristic shown in Fig. 4 the high resistance state is represented by lines 50a, 54a, which lines 52a, 56a represent the low resistance state, the line between threshold voltages Vthf and - Vthr representing a high resistance condition common to both states. Switching from the low to the high state is achieved by passing a forward current greater than If across the heterojunction and reversion to the low state by applying a reverse bias in excess of the threshold Vrs to the device. The states can be sensed by application of a reverse bias voltage Vrr to give a read-out current 71 or 77. Typically a plurality of devices are formed in a monolithic matrix in which they are connected at the intersections of X and Y word and bit lines, the characteristic being such that sneak paths are effectively eliminated.

Abstract: 294,807. Hansen, H. C. Oct. 22, 1927. Coin action, mechanical-connection; testing edge for milling.- In a coin-freed vending machine of the kind having mechanism for distinguishing between coins having milled-edges and those with smooth edges, the milled-edge coins freeing the machine, the coin 60 inserted through a shoot 1, Fig. 1, drops to a passage-way 2, Fig. 2, where it rests on rollers 9 and acts as a pinion to transmit the downward movement of a toothed rack 19 to a rack 14 carried by a bar 10 which is connected to the releasing mechanism. The rack 19 is mounted on a lever 20, 21 controlled by a spring 27 and pivoted on a bar 22 which is connected to the opening member or drawer of the machine. At the beginning of the opening movement of the delivery member, the bar 22 begins to move down and the rack 19 leaves a stop 29<1> so that it is swung forwardly into engagement with the coin which it moves into engagement with the rack 14. Rotation) of the coin then moves the rack 14 up to actuate the releasing mechanism which permits full downward movement of the bar 22. The rack 14 is held in its uppermost position by a spring catch 16 until this is released by a cam 61 on the bar 22 at the end of the return movement of the latter. During the downward movement of the bar 22, a bevel 52 on a frame 53 carried by it engages a pin 51 on a lever 47, 48 so that the arm 47 raises the rear plate 5 of the passage-way 2 by engaging a pin 50 thereon. The plate 5, which swings on links 6, engages the short arm 56, Fig. 2, of a lever 55, 56 and moves the end 58 of the long arm 55 into the passage-way 21 to push the coin out into a shoot 46. The bar 22 also carries a cam 37 - - 40 against which is pressed by a spring a pin 36 on an arm 35 extending from a flap pivoted at 33. The flap is thereby moved, with rests when the pin 36 engages the parts 37, 39, from left to right in the funnel 43. When the pin 36 engages the part 39 the flap closes the shoot 46 into which the coin is then pushed. When the flap moves further, the coin drops into the funnel and is guided down the shoot 44 to the money-box. If a smooth-edged coin is used, the rack 14 is not moved and the bar 22 cannot be pulled down to its full extent. It moves only far enough for the flap 34 to close the shoot 46 containing the coin. When the bar is pushed back to restore the parts, the coin is guided down the shoot 45 out of the machine.
