Title: An improved mechanism for controlling the feed of cartridge cases of small arms ammunition to machines
IPC: F42B33/02
Filed: 1951-06-22
Abstract: 697,133. Feeding cartridge cases to machines. TAYLOR & CHALLEN, Ltd., and CHALLEN, H. D. June 16, 1952 [June 22, 1951], No. 14824/51. Class 9(i) The feed of cartridge cases 4 to a machine is controlled by a camactuated trap door 5 from which the. cases pass to a shoot 6, there being a feeler 34 associated with the shoot actuated through linkage by a separate cam. The arrangement is such that in the event of a feeler contacting a cartridge case in the shoot the linkage assumes a position to prevent opening of the cam - controlled trap door. The machine shown has a rotating shaft 9 fitted with the two cams 8, 18. The cam 8 acts on a pivoted arm 10 which is connected by a rod 14 to an arm 15 keyed to a shaft 16. A bell crank lever 17 on the shaft has one arm 17a engaging in a slot in the trap door 5. The other cam 18 acts on a pivoted arm 20 which is connected by a link 23 to the part 24a of a U-shaped lever 24 whose ends are pivoted at 25 to the arms 26a of L-shaped levers 26. A central projection 33 on the lever 24 is adapted to contact the spring- controlled feeler 34 which pivots freely on the shaft 16. Operation. In normal use the cam 8 causes the arm 17a to close the trap door and a spring 12 acting on the arm 10 opens the trap door, the cam 18 meanwhile causing the projection 33 to depress the feeler 34 into the shoot. If, however, the feeler strikes a cartridge case, the lever 24 is caused to pivot about the point of contact of the projection and feeler, thus causing the levers 26 to swing about their pivots against the action of a spring 29. This movement causes a cross-member 36 connecting the levers 26 to engage a step 17b' of the bell-crank 17, thus arresting the opening movement of the bell-crank and trap door when the lever 10 registers with a dwell in the cam 8. The step 17b prevents the return of the levers 26 until almost the end of the cycle, at which point the lever 10 is moved by cam 8 slightly to the right to effect unlatching.

Abstract: 1,095,174. Photographic methods of producing blushed images. RANK XEROX Ltd. April 8, 1965 [April 27, 1964], No.14902/65. Heading G2C. Blushed images in photo-sensitive materials are produced by (i) uniformly blushing the material before imagewise exposure and then treating it with a solvent or heat to soften and clarify the unexposed areas, (ii) imagewise exposing the material, uniformly blushing and then treating it with a solvent or heat to soften and clarify the unexposed areas or (iii) imagewise exposing the material and then treating it with a solvent long enough to soften the unexposed areas only and then drying to produce a clear image on a blushed background. Blushing is achieved either by coating or treating the photo-sensitive layer with a solvent and allowing the layer to dry in a humid atmosphere. Method (ii) requires a prolonged treatment with solvent vapour to produce overall blushing whereas in method (iii) the treatment is shorter so that only the unexposed areas blush. The specified photo-sensitive materials are polyvinyl cinnanate and the glycerol ester of hydrogenated rosin.

Title: Improvements in and relating to automatic reclosing circuit breaker systems
IPC: H02H3/07
Filed: 1923-06-07
Abstract: 217,417. British Thomson-Houston Co., Ltd., (General Electric Co.). June 7, 1923. Protective arrangements.-In an automatically-reclosing circuit-breaker system in which the circuit-breakers are reclosed a predetermined number of times on being released on overload after which the reclosing mechanisms are rendered inoperative, common driving means is provided for operating the reclosing mechanisms of the circuit-breakers. A number of circuits, for example, a supply circuit 1 and a feeder circuit 2 is connected to bus-bars 3 through circuit-breakers 5, 6. Each interrupter is provided with a closing toggle 7 consisting of links 10, 11, the links 10 being connected to the circuit-breaker rod 12 which is spring-urged to the " off " position and one end of link 11 being connected to a link 16 moving about a fixed pivot 17. The toggles are operated by cams 9 on a shaft 20 driven bv a motor 21. An electromagnet 15 is arranged near the link 16 so that when the core 13 is drawn inwards to the dotted position against the spring 18 the link 16 engages the free end of the core during rotation of the cam 9 so permitting the toggle 7 to be overset to close the circuit-breaker 5 or 6. Normally when the circuit-breakers are closed circuits for the retaining coils 15 are completed from control bus-bars 22 fed by a transformer 23 through contacts 27 of an overload relay 26, contacts 29<1> of a time relay 29 and switches 43, 45. On operation of a relay 26 this circuit is broken and the corresponding circuit-breaker 5, 6 is opened by its spring, movement of the link 16 allowing the toggle 7 to collapse. The circuits of relays 29 and 31 are simultaneously made through the upper contacts of the relay 26. The relay 29 immediately opens its contacts 29' and the core 33 of the notching relay 31 advances the spring-controlled ratchet wheel 34 through one tooth at the same time removing the arm 39 from the spring-controlled pawl 38 which retains the plate 37 in its advanced position. As the relay 26 falls on opening of the circuit-breaker the circuit of relay 24 is made. This relay completes the circuit of the motor 21 causing rotation of the cams 9. The core of the. relay 29 after completing its retarded return movement again bridges contacts 29<1> and recloses the circuit of the coil 15. The core 13 now moves in the path of the link 16 enabling the toggle 7 to overset and the circuit-breaker 5 or 6 to be reclosed. If this circuit-breaker is not re-opened within a predetermined time the retarded member 39 of the notching relay falls and disengages the pawl 38 from the ratchet wheel 34, which snaps back against the stop 39, but if the circuit-breaker is reclosed a predetermined number of timea with less than a. predetermined time interval between each reclosure, the arm 35 on the wheel 37 moves the bridging member from contacts 43 so rendering the reclosing means inoperative. A hand switch 45 is included in each re-closing circuit.

Abstract: 691,927. Shuttle stop motions; timing shuttles. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 2, 1951 [June 16, 1950], No. 15162/50. Classes 142(i) and 142(ii) Arrival of a shuttle in a shuttle box breaks the primary circuit 7 of a sparking coil, causing a discharge between a rotating pointer 1 and a conductive segment 3 or 4, the segment 3 corresponding to a correct shuttle timing. If the shuttle boxes early or late, the discharge takes place at a segment 4 and triggers a gas-filled tube 13, thereby completing a circuit through a supply 14 and a relay L to stop the loom. To avoid the open sparking between the pointer and the segments, a small discharge tube may be mounted on the pointer, the tip of which then carries a brush wiping the segments. In a form for visual timing of the shuttle (without operating a stop motion), the segments are replaced by a graduated scale.

Title: Recovery of by-products in the manufacture of phenol
IPC: C07C7/04
Filed: 1949-06-08
Abstract: In phenol production by acidic decomposition of isopropylbenzene peroxides, the reaction mixture is fractionally distilled under non-acid conditions, i.e. pH not below 5.  Thus the mixture is washed with water to remove the acid catalyst, followed by small amounts of alkali to remove organic acidic by-products and to produce the desired pH change without removing appreciable amounts of phenol. Small amounts of phenol and acetone may be recovered from the wash water.  Preferably also the peroxides are alkali-washed before contact with the acidic decomposition agent.  Fractional distillation of the washed decomposition products yields successively isopropylbenzene, a  - methylstyrene, phenol, acetophenone and cumylphenol, the last two preferably under reduced pressure. Alternatively, after the first- and second-named have passed over, the phenol and acetophenone are removed by steam distillation and the cumylphenol extracted from the residue with alkali.  The cumylphenol may then be treated as in Specification 670,444 to increase the overall yield of phenol.  An example is given of the process.
