Title: Improvement in taper attachment for lathes
IPC: B23B5/38
Filed: 1940-07-11
Abstract: 552,703. Lathes. JONES & LAMSON MACHINE CO. July 11, 1940, No. 11575. Convention date, July 11, 1939. [Class 83 (iii)] The slide rest of a lathe is provided with mechanism for feeding it to produce taper work during traverse, the two feeds being interconnected and operable by a single control so that either parallel or taper turning may be effected. The slide rest 11, Figs. 1 and 7, movable transversely on the saddle 4 is normally operable by a screw 15 engaging a nut 21 which is normally held against axial movement by a split collar 22 clamped by a screw 24 freely mounted in one part of the collar and engaging a nut adjustably secured in the other part. The nut 21 is provided with a projection 40 on which is swivelly mounted a block 41 engaging a groove in a plate 45 which can be set at different angles, according to the taper required, on a base bracket 46 which is mounted in guides extending in the direction of motion of the saddle. A projecting arm 65 on the bracket 46 carries a rockshaft 72 to which is fixed a finger 71 engaged with any of a number of notches 70 in a fixed shaft 68. When so engaged, the bracket 46 is held stationary when the saddle is traversed and the inclined slot in the plate 45 acting on the nut 21, which at this time is unclamped, causes the nut to move axially which movement combined with the movement of the saddle produces the tapering movement of the tool. When the finger 71 is disconnected from the bar 68, the bracket 46 moves with the saddle and the nut, which at this time is clamped, functions to allow ordinary feed by the screw 15. The mechanisms are interconnected by an arm fixed to the shaft 72, connected by a link 81 to one arm of a bell-crank fixed to the screw 24, the other arm 83 being connected by a link 86 to a control handle 88, the parts being so arranged that when the screw 24 is in clamping position, the finger 71 is clear of the notches 70. The finger 71 may be slightly narrower than the width of the slots 70 so that a slight lost motion occurs. This has the result that on the return stroke of the tool there is a slight straight movement before the commencement of the taper movement so that the tool is slightly spaced from the work to prevent damage thereto.

Abstract: 1,135,838. Uranium hexachloride. JAPAN ATOMIC ENERGY RESEARCH INSTITUTE. 17 March, 1966 [18 March, 1965], No. 11705/66. Heading C1A. [Also in Division G6] Spent uranium-containing nuclear fuel is reprocessed by chlorination with an agent containing chlorine and carbon but no hydrogen, passing the UCl 4  and fission product; chlorides through a bed of barium chloride which absorbs UCl 4  vapour, desorbing fission product chlorides from the bed with an inert gas and then passing chlorine through the bed to oxidize UCl 4  to UCl 6  which vaporizes and is collected. The fuel may be in the form of uranium metal, UO 2 , U 3 O 8 , or UC 2 ; UO 2  is pulverized by repeated oxidation and reduction. The chlorination may be carried out with CCl 4 , phosgene, hexachloroethane, tetrachloroethylene, hexaohlorobenzene, cyanogen chloride, hexachlorophenol, tetrachloroquinone, trichloromethyl chloroformate, tricyanogen chloride, or hexachloro - 1 ,3-butadiene, at 450-700 C. The chlorinating agent may be mixed with argon or nitrogen. The BaCl 2  bed is suitably graded in temperature from 500 C. at the inlet to 150 C. at the outlet. Desorption of fission product chlorides is carried out at about 500 C. using CCl 4  or COCl 2  diluted with argon, nitrogen, or hydrogen; alternatively argon or nitrogen may be used alone. The chlorine used for the oxidation to UCl 6  at 400- 700 C. may be mixed with CCl 4 , argon, or nitrogen. To decontaminate the UCl 6  further, it may be reduced to UCl 4  and the absorption process repeated.

Title: Improvements in photo-lithography
IPC: G03F5/04
Filed: 1927-05-02
Abstract: 274,422. Muller, E. July 14, 1926, [Convention date]. Photo - mechanical printing - surfaces; retouching.-A screen negative for photolithographic printing is produced by exposing a sensitive plate through a screen placed at such a distance therefrom that the graining consists of black nuclei fading towards the edges, and retouching the negative (1) on the back by local application of an agent such as graphite after coating with matt varnish, and (2) on the front by local etching with a highly diluted etching agent such as potassium cyanide admixed with a viscous substance such as gum or rubber solution to prevent spreading. A highly sensitive dry plate is used for making the negative, which is printed on the surface or plate under strong illumination incident perpendicularly to the plate. The distance of the screen from the plate in mm. may be determined by dividing the constant 175 by the number of lines per cm. on the screen.

IPC: B65B13/28
Filed: 1923-05-01
Abstract: 213.787. Gerrard, A. J. May 1, 1923. Wire strainers.-In an apparatus for wiring bales, movement of a lever in one direction actuates the tensioning means, whilst movement in the reverse direction actuates both the twisting and cutting means. One end of the binding wire is bent back on itself slightly and is held in a slanting recess 46, whilst the other end, after the wire has passed through the slotted twisting pinion, around the bale and again through the pinion is secured between serrated clamp elements 48, both of the anchoring means being formed at the ends of arms 36 pivoted at 38 and normally drawn together towards each other by a spring 40, Fig. 2. The arms are moved away from one another by the rotation of cams 11, 12 about a shaft 9, the cams acting on rollers 42 formed on lugs or projections 36a from the arms. An annular gear wheel 13 is housed within a circumferential recess in the outer face of the cams 11, 12, these members being in the form of flanges on discs that are bolted together and are free to rotate on shaft 9. A locking dog engages a recess 35 in the gear wheel 13 to prevent movement thereof during the rotation of an actuating lever 18 in the direction C, Fig. 1, the lever 18 comprising a yoke 19 straddling the cams and carrying a lug 20<a> engaging a portion of the cam face to rotate them and to strain the wire. The yoke is pinned to the shaft 9 at 21, Fig. 2, and the shaft carries a pin 22 coacting with a lug 23 on the internal face of the cam 12 to assist in the rotation thereof. When the lever has been rotated approximately 180‹ from the position shown in Fig. 1, a pin 45 on the cam 11 acts upon the catch 32 to withdraw it from the recess in the gear wheel 13. On the commencement of the return stroke of the lever, spring-pressed pawls 26 carried on the yoke 19 engage a pair of recesses in the periphery of the wheel, so that the latter is rotated to rotate the slotted pinion 14, formed on a slotted shaft 20, through which pass the two portions of the binding wire to be twisted together. Further rotation of the lever causes the pawls 26 to stroke the catch 32, whereby the catch is again pressed into the recess in the gear wheel and the pawls are withdrawn from their recesses. Subsequently a pin 56 on the yoke 19 strikes a pivoted cutter 51 to depress the same and sever the spare wire, a spring 57 restoring the cutter, and a spring 34 restoring the cams.

Abstract: 1,039,502. Amplifying circuits. GENERAL ELECTRIC CO. March 19, 1965 [May 11' 1964], No. 11816/65. Heading H3T. In a hybrid directcoupled amplifier having an electrometer valve as input stage and having overall negative feedback, limiters are used to prevent the negative feedback path acquiring an appreciably positive potential, e.g. on switching on or off, and so causing momentary grid current in the valve which would permanently disturb the static condition of the amplifier. The limiter may comprise one or more diodes connected in series and shunting the feedback path to earth (Fig. 1, not shown). In a second embodiment, the amplifier comprises electrometer valve 23 with its heater fed from the H.T. + line via series resistor 32, grid bias being obtained by means of resistor 27<SP>1</SP> between the other end of the heater and earth. Valve 23 is direct coupled to NPN transistor 24 which in turn is direct coupled to PNP transistor 25, both being in common emitter connection. The collector of transistor 25 is back-coupled to the grid of valve 23 via lines 47, 48, measuring meter 4 and a potentiometer comprising resistors 3, 5. Limiting is performed by PNP and NPN transistors 50, 51, respectively, with their emitter-collector paths connected across the collector load resistor 45 of transistor 25 and with their bases connected to receive switching surges from the H.T. + line over capacitors 63, 66, respectively, the charging rates of these capacitors are reduced by the connection of diodes 70, 71 across the respective discharge resistors 61, 65.

Title: Process of producing coloured pictures
IPC: G03F1/00
Filed: 1933-04-24
Abstract: 405,147. Reproducing coloured pictures. MULLER, F. H., 30, Brehmstrasse, Dusseldorf, Germany. April 24, 1933, No. 11943. [Class 40 (iii).] In a process for the reproduction in ink of multicoloured pictures, a coloured negative is scanned for each colour point by point by means of a narrow beam of light which passes through a suitably coloured filter before traversing the negative to act upon a photo-electric cell, which reacts and indirectly actuates a mechanical device for marking dots in the corresponding colour on a support, thereby mechanically producing the picture, the operation being repeated for each colour. A carriage 2, which is reciprocated by a motor 1 and is shifted laterally after each reciprocation, carries a coloured negative 7 of the picture to be copied, and a paper sheet 18 on which the copy is to appear. A light beam 4 passes through a coloured filter 5 and the negative 7, and falls upon a photoelectric cell 8, which is in the circuit of a transformer primary 12, battery 9, and condenser 10 ; across the latter a vacuum discharge tube 11 is connected, such that as soon as the condenser is fully charged it discharges through the tube 11. The current impulse at each discharge causes the relay 14 to be energized. Connected to the relay 14 is a needle 15 which extends through a colour-containing vessel 16 and a narrow tube 17. Each time the condenser discharges, the relay 14 is energized and pulls the needle 15 downward on to the paper 18, thereby depositing a coloured dot. The number of dots made in any time depends upon the amount of light passing through the negative 7, so that if the negative is dense few dots are made and the picture appears uncoloured and if the negative is clear, the reverse occurs. Each colour is applied successively using a suitable colour filter 5 ; and by varying the magnitude of the condenser 10, the strength of the copy can be adjusted. A coloured positive can be employed instead of the negative 7, the apparatus being suitably modified.
