Title: Improvements in the manufacture and production of carbon papers and the like
IPC: B41M5/10
Filed: 1928-10-29
Abstract: 321,538. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 29, 1928. Carbon papers.-In the preparation of wax compositions for coating carbon paper and the like, the usual oils employed as softening-agents are replaced wholly or in part by liquid or lowmelting aromatic or hydroaromatic substances, for instance aryl phosphates such as tri-cresyl phosphate, high molecular bases or esters such as methyldiphenylamine, and phthalic acid esters of ethylene glycol mono-alkyl ethers. In an example tri-cresyl phosphate is added to molten carnauba wax and the mass is treated with a solution of methyl violet base in oleic acid. A highly-bleached montan wax prepared for instance in the manner described in Specifications 296,145 and 308,996, [both in Class 91, Oils &c.], may be employed instead of carnauba wax.

Abstract: 283,708. Douglas, W. Dec. 10, 1926. Winding webs.-Relates to the winding or reeling of multiple strips or webs of paper, two or more of which have forms printed thereon and adapted to register with one another so that duplicate or manifold copies of entries made upon the outermost forms by a typewriter or other device are correctly positioned, the underlying strips being provided with a carbonized backing or having carbon sheets interposed between them. The outer ends c, Fig. 3, of separate strips a<1> - - a<3> carried by reels b<1> - - b<3> are registered upon a core d and the strips are wound to form a reel e wherein the final ends f<1> - - f<3>, Fig. 4, become relatively staggered in the usual manner, due to the differences in the tensions in the individual strips and the varying diameters of the reels. The ends f<1> - - f<3> are then applied to a core g, Fig. 5, in the same staggered relationship in which they terminated on the roll e, and the strips are rewound to form a final reel h in which their outer ends terminate in register, so that when withdrawn for use the forms thereon are superposed correctly, and, during the unwinding, issue tangentially from the reel, whereupon the parts that are out of register become superposed correctly in passing from the reel to the typewriter or other device. The final outer ends of the strips of the re-reeled roll mav be secured together by folding, pasting, wire-stitching, &c. During the final reeling the outermost strip may be pressed upon the reel h by a jockey guide-roller.

The striker pin 6 can be displaced into one or the other of two openings 8 or 9 in the impact plate 4 so that it can be directed towards the centre or the edge of the base of a cartridge when the latter is located in the cartridge chamber. A guide member 23 surrounds the striker pin 6 and, being urged by a spring 15, retains it in the desired position. A safety roll 10 aligns an end 11 of the striker pin 6 with a hammer 12, Fig. 1, when the firearm has been cocked. A trigger 13 releases the hammer 12 which drives the pin 6, against the force of the spring 15, so that a point of the pin 6 projects from the inpact plate 4 to fire the cartridge. The pin 6 is returned to its rest position by the spring 15, an abutment 14 of the pin resting against the safety roll 10. The latter can be rotated to the safe position shown in Fig. 2, the end 11 of the pin 6 being displaced downwardly out of the path of the hammer 12. The impact plate 4 is provided with a groove 22, Fig. 3, which facilitates displacement of the striker pin 6 from the opening 8 to the opening 9 and vice versa, when the safety roll 10 is in the safe position and when the abutment 14 of the pin 6 is received in a recess 21 provided in the safety roll 10.

Filed: 1972-12-01
Abstract: 1418685 Harness STAUBLI LTD 1 Dec 1972 [2 Dec 1971] 31787/75 Divided out of 1418684 Heading D1E An apparatus for performing the method of Specification 1418684 comprises a brake 70a for the elastic lingo cord 7, a yarn accumulator and pretensioner 7c, guide eyes 70f, a cutterclamp 70e, a heald fork 79, a heald holder 75 and a tensioner 76. In use with the members disposed as in Figure 1 with the cord 7 in the clamp 70e the brake 70a is applied, a lingo anchorage 8 is applied to the cord 7 and the tensioner 76 is moved to apply tension to the cord. As the tension is increased the roller 70d of the pretensioner 7c is raised and cord 7 is withdrawn through the cutter-clamp 70e. When a predetermined length of cord has been withdrawn the clamp 70e is closed and the brake 70a is opened to allow the roller 70d to fall. A heald (9) (Fig. 3, not shown) is then placed in the holder 75 and passes through a forked heald guide 79. The guide 79, holder 75, cutterclamp 70e and guide eyes 70f are then raised to lodge the cord 7 in the heald (9). The heald guide is then retracted leaving the cord wedged in the heald and the cutter 70e operated to sever the cord between the cutter and heald and to retain the other end of the cord in the clamp 70e ready for the next cycle. The holder 75 is then pivoted to the position of Figure 5 and tension applied to the cord to wedge it even more firmly in the anchorage 8 and heald (9).

Title: Electrodeposition of nickel
Inventor: FLINT GEORGE NORMAN
IPC: C25D5/18
Filed: 1964-08-05
Abstract: <PICT:1033100/C6-C7/1> In the process of nickel plating disclosed in the parent Specification using a batch containing 500 to 700 g. per litre of nickel sulphamate, plating is first-effected at a high C.D. giving a dull plate and then at a C.D. below 70 A.S.F. giving a bright plate.  No brightening agents are required.  A number of wires or strips are fed side by side over a roller 3 and are led individually under rollers 4 immersed at different depths in the plating back. The strips pass between pairs of anodes which are more widely spaced at the end of the bath to reduce C.D. to the required value.  Resistors 12 may also be included to adjust this figure.  In alternative arrangements (not illustrated) shields may be used in the second stage (Fig. 3, 4), the last groups of anodes are mounted remote from the wire (Figs. 5 and 6). "Thief" cathodes to control and regularize the plating as alternatives to shields are refused to. The initial C.D. may be 300 A. S. F. or more and then reduced to 30 A.S.F. within progressively or abruptly.

Title: Improvements in automatic telephone exchange systems
IPC: H04Q3/00
Filed: 1953-11-17
Abstract: 745,026. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 17, 1953 [Nov. 20, 1952], No. 31862/53. Class 40 (4). In a system in which the subscriber's loop, which includes a voltage source, is extended to a connecting circuit over a transformer, a pair of valves 27, 28 are fired alternately by pulses of opposite polarity arising from the opening and closing of the loop, such as by dialling, and control an auxiliary valve 84 which serves to restore the connecting circuit when the subscriber hangs up, but is unable to fire during dialling on account of an interposed integrating circuit 82, 83. The lifting of the handset at substation 1 applies a negative pulse to the common point 13, causing tube 14 to fire and back-off the remaining tubes 14 commoned to that point. Tube 14 in firing produces a voltage drop at point 20 and through vacuum tube 23 a positive pulse on the grid of tube 27 which fires. 'The leading and trailing edges of subsequent dialling impulses fire tubes 28 and 27 respectively and in the case of the latter, the potential across the resistor 30 in combination with the potential across condenser 32 resulting from the preceding firing of tube 28 overcomes the back-bias on rectifier 37 to apply a positive pulse to the counter TS, of which only three of the counting tubes are shown. When the digit is complete the potential across the cathode resistor across the last tube fired fires the corresponding connecting tube 66. Tubes 66 corresponding to the intermediate tubes are not fired because of the limited duration of the pulses arising on the intermediate tubes and the long time-constant of the interposed networks 62, 63, 64. Tube 66 in firing connects the substation 1 to the succeeding switching stage or to a line over transformers 17 and 70 and fires tube 76 to restore the counter TS to normal. Tube 51 is also fired by tube 76 so that impulses of a succeeding digit may not re-actuate the counter of the stage shown. When the subscriber at station 1 finally hangs up his receiver, the opening of the loop fires tube 28 which in turn fires tube 84 to restore the whole apparatus to normal. The network 82, 83 has a long timeconstant to prevent clearing down during dialling.

Title: Improvements in electron multiplier circuits
Inventor: BRASH ROBERT ALEXANDER
IPC: H01J43/30
Filed: 1966-07-15
Abstract: 1,179,846. Gain control arrangements; photo-electric distance measuring. G. & E. BRADLEY Ltd. 14 July, 1967 [15 July, 1966], No. 31958/66. Headings H3Q and H4D. [Also in Division G1] In a variable-gain electron-multiplier circuit including an electron multiplier connected in series with a load, and with means for applying a varying voltage across the multiplier to vary its gain, means are provided for applying to the load a signal in opposition, and substantially equal, to an unwanted signal generated in the multiplier and applied to the load when the varying voltage is applied across the multiplier. The arrangement is described as applied to a laser distance measuring device in which reflected light pulses are amplified in photomultiplier 10, compensation for diminishing signal strength as distance increases being obtained by pulsing the anode current in the multiplier. Gain-controlling pulses are applied over a shaping network 16 to the grid of valve 15 to drive it conductive, producing a voltage drop across resistance 14 which is applied to the cathode of photo-multiplier 10 and also to the dynodes via a potentiometer network 24. The cathode circuit of valve 15 contains a further pulse-shaping network 17, and diodes 18, 20 connected between the anode and sources of fixed bias respectively determine the minimum and maximum voltage across the photo-multiplier. In such an arrangement an initial surge of current (22, Fig. 3, not shown) occurs in the multiplier such as to prevent measurement at near distances: the invention overcomes this by deriving a pulse from the dynode of the multiplier which is nearest to the anode and applying it via capacitor 25 to a transistor amplifier 26. This amplifies and inverts the pulse and applies it in opposition to the anode of the multiplier via capacitor 31 which is adjustable in order to obtain exact compensation. Alternatively, a pulse may be derived from the current to the dynode by connecting in series with it the primary of a ferrite cored transformer, the secondary of which is so connected to the anode as to apply a suitable compensatory pulse to it.

Title: Method and apparatus for the transfer of molten metal to casting  means
IPC: B22D39/02
Filed: 1971-07-09
Abstract: 1363098 Delivering measured quantities of liquid A H ANDERSSON & CO AB 9 July 1971 [22 July 1970] 32295/71 Heading B8N [Also in Divisions B3 and F4] Apparatus for transferring molten metal from a bath 31 to a casting machine 32 comprises a ladle 18 and means for tilting the ladle with a smaller initial tilting movement followed by a larger further tilting movement distinct from said smaller movement. The ladle is carried by a substantially horizontal arm consisting of parts 19, 20 and 27, said arm being rotatable about an axis 10 to transport the ladle from the bath 31 to the casting machine 32. The movement of the ladle is controlled by wheels 15, 16 and 17 running along tracks 12, 13 and 14 respectively, the smaller tilting movement being controlled by the wheel 16 and track 13 and the larger movement by wheel 17 and track 14. After the ladle has been filled with molten metal in the manner disclosed in Specification 1,363,097 the arm 19, 20, 27 is moved in an anti-clockwise direction about the axis 10 to transport the ladle to the casting machine. The initial smaller tilting movement is initiated by wheel 16 running up an incline or step 37 at the end of track 13. This causes the parts 19 and 20 of the horizontal arm to twist relative to the part 27 about the link 28. Further movement of the arm about the axis 10 is prevented by a stop 38 at the end of track 12 so that the said twisting movement results in the links at a pivot 45 assuming an upwardly convex position and those at pivot 40 an upwardly concave position. Continued movement of the wheel 17 along an inclined part 56 of the track 14 increases this bending movement and this causes a further twisting of the arm parts 19 and 20 and tilting of the ladle 18 to discharge the metal therefrom. To ensure that no molten metal remains in the ladle, the track 14 undergoes a relatively large change in height to cause overtipping of the ladle.

Abstract: 1453349 Programming I.C. memory arrays NATIONAL SEMICONDUCTOR CORP 23 July 1974 [3 Dec 1973] 32507/74 Heading G4A The frequency with which voltage stressing power pulses are applied to programme an I.C. memory array is controlled so that the temperature of the IC die does not exceed a preselected value. The invention may be applied to a voltage stressed programmable read-only memory having fusible links or, in the embodiment described, chargeable floating gates, the temperature being determined by sensing the voltage drop across phantom diodes 21 (Fig. 2) between source terminals of transistors 19 and the bulk region of the die. The programming pulses are supplied by a circuit 16, controlled from a one-shot 17 which applies a 10-15 millisecond pulse to buffer amplifier 32<SP>1</SP> connected to the programming input V t  and to NAND gate 34 to render conductive transistor 35 so that line 38 goes to a voltage level V SS  + 12 and lines 39 goes to a voltage V SS -50. At the end of the pulse the voltage at terminal V BB  decays so that, after a time dependent on the temperature of the die, sensing amplifier 23 delivers a low output signal to trigger the oneshot 17 to repeat the operation. A number of devices may be programmed in parallel with the rate of application of power pulses being determined by the voltage across the diodes of the hottest die.

Abstract: 213,312. Marks, E. C. R., (Toledo Scale Co.). Nov. 28, 1922. Pendulum-weight apparatus; relieving and locking mechanism. - In weighing- apparatus of the type in which the load is offset both by a beam lever and by automatic mechanism, and in which means are provided to lock both the lever and the automatic mechanism, the lever locking means are formed so that the lever is raised to its fully-elevated position during the first part of the movement of the raising member and then held in such elevated position during the remainder of the movement. The lever may be formed with an arcuate surface 22 so that after the member 20 has elevated the beam by engagement with the projection 21, no further movement is made, or the raising member 20<a> may be formed with an arcuate surface 22<a>, and a projection 21a. The invention is shown in Fig. 1 embodied in a scale of the construction shown in Specification 173,521. The member 20 is connected by a link 23 to an arm 24, operatively connected with a cam 25, which supports the foot 26 of a rod 18 carrying hooks 17 adapted to engage the pendulum-weights 12 when the weights are in their lowest position. The arm 24 is operated by a handle 27 to elevate the lever 3, thus ,allowing the weights 12 to fall, while the cam 25 holds the hook 17 in an elevated position, until further movement of the arm 24 and the cam 25 allows the hooks to engage projections 19 on the weights 12. A lost-motion connection between the arm 24 and cam 25 may be provided to enable the lever 3 to be locked apart from the pendulum mechanism. The cam 25 may be operated by a handle in the scale-column through a rod 29.
