Abstract: 858,011. Pushing jacks. DOWTY MINING EQUIPMENT Ltd. March 14, 1958 [March 15, 1957], No. 8670/57. Class 78 (3). In a device for shifting mining machinery, such as a conveyer 16, a jack 14, 17 pivoted at one end to the conveyer 16, extends between sideplates 7 rigidly secured to a strut 1, 2 and rests, in its inoperative position, on a convex skid 10 secured to the side-plates, links 23 pivotally connecting the other end of the jack to the side-plates. On rocking the strut manually into engagement with the roof, and on extending the jack, the links 23 pull the side-plates 7 to the right, as shown, so causing a spike 4 on the strut to bite into the roof and thereafter the conveyer to be pushed to the left. On retracting the jack, the links 23 push the side-plates to the left on the skid 10, and the strut swings clear of the roof. The jack is operated hydraulically, fluid being supplied through a valve control-box 22 and hollow piston-rod 14 to the cylinder 17. The top of the jack is protected by a shroud 20 carrying a cover-plate 21 extending over the valve control-box 22. The strut 1, 2 is telescopic and may be provided with an hydraulic jack.

Title: Electrodeposition of uranium compounds
IPC: C25D9/08
Filed: 1946-03-20
Abstract: 832,494. Electrodeposition of salts of uranium and thorium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 20, 1946 [March 24, 1945], No. 8700/46. Class 41. Insoluble uranium salts are cathodically deposited by electrolyzing an aqueous solution of a uranyl salt to reduce the uranyl ion to the tri- or tetra-valent uranium ion in the presence of a negative ion which forms an insoluble salt with the reduced ion. Films containing up to 1000 Á gms. per sq. cm. of uranium calculated as metal may be deposited. As described the uranyl salt is the nitrate and the negative ion is fluoride provided by sodium fluoride and electrolysis is effected to deposit uranium fluorides on a platinum cathode to a density in uranium of between 250 and 400 Á gms. per sq. cm. for use in analysing polyisotopic uranium samples. The electrolysis is effected in a cell formed by a glass cylinder 16 provided with fixed hooks 17 secured on a platinum foil 11 on a thicker platinum disc 12 which receives the cathode connection by a rubber band 22 engaging hooks 18 arranged for limited vertical movement in a glass plate 15, the anode being a platinum wire spiral 20 which also acts as a stirrer. A fillet of beeswax is provided to render the joint between cylinder and disc liquid-tight. Gold or palladium may be used as the backing disc 12 instead of platinum. The platinum foil bearing the insoluble uranium compound is heated to burn off the beeswax and convert the compound to U 3 O 8 . The Specification as open to inspection under Sect. 91 describes also the cathodic deposition of thorium ferrocyanide from a solution of thorium nitrate and potassium ferricyanide, the deposit on the platinum foil after washing being first ignited over an oxidising flame and then heated over a steam bath while submerged in hydrochloric acid to extract the iron oxide and leave thorium oxide in a film density in thorium of 20 to 500 Á. gms. per sq. cm. This subjectmatter does not appear in the Specification as accepted.

Abstract: 251,250. Wagner, A., (Assignee of Schiffer, P.). April 27, 1925, [Convention date]. Regulating head of liquid directly. - A vessel A is divided by a partition j into a water tank l and a gas container g into which water from the tank l passes by a pipe m. Secured to the exterior of the gas container g is a feed-regulator f baving a passage h through which water from the container g passes into the regulator f and thence passes through a branch d of a pipe b controlled by a cock c to a gas generator a containing a charge of carbide. The upper end of the pipe b opens into the upper portion of the feed-regulator f, and the portion of the pipe b below the branch d serves to convey both water to the generator a and gas to the regulator f, which gas passes either through a delivery pipe k or through the passage h into the container g. In case of shortage of the generated gas, gas from the container g passes through a siphon i into the regulator f and thence to the delivery pipe k.

Title: Automatic weft replenishment for looms
IPC: D03D45/20
Filed: 1950-04-11
Abstract: 695,456. Automatic weft-replenishing looms. OFFICINE GALILEO SOC. PER AZIONI. April 11, 1950 [April 11, 1949], No. 8850/50. Class 142(iii) The :pattern card of a change-box loom has, in addition to the elements that control the shuttle boxes, other elements corresponding to the weft colours and which initiate the release from the magazine of a bobbin of the correct colour. Vertical movement of shuttle boxes 2 and horizontal movement of boxes 3 is effected by mechanisms 4 and 7 respectively, controlled by pattern card 8. Each of the additional elements 13, which may be a hole or a pin, closes one of a number of switches 14-17 corresponding to the weft colours.: If the weft feelers 18-21 indicate that the shuttle to be picked next is almost exhausted, a bobbin of the same colour is released from the magazine 28 and retained by clips 26, 27 The release of bobbin may be by'electrical means including electromagnets 75-78 or by mechanical or hydraulic means. One of the electromagnets, when energized, attracts one of the armatures 51-54, the other end of the armature being engaged by a moving bar 55, one of the members 43-46 is thereby moved, and one of the spoons 79 rotated to release a bobbin. Cam mechanism 30-32 operates a shuttle feeler 29 and also the transfer hammer 25, the latter having two movements. The first occurs at back centre and knocks the bobbin from the clips 26-27 to a clip 23 on the slay, the second movement transfers the bobbin into the shuttle as the slay moves forward. The exhausted pirn is expelled through a slot in the bottom of the shuttle. The shaft 29<SP>1</SP> of the shuttle feeler also carries scissors and grippers for manipulating the weft end.

Abstract: 829,300. Electric measuring systems. PROCHAZKA, M. March 21, 1956, No. 8876/56. Class 40 (1). [Also in Groups XXXV, XXXVI and XXXIX] Apparatus for measuring the torsional oscillations of a rotating shaft comprises a cylindrical magnet rigidly attached to the shaft, surrounded by a coil resiliently attached to the magnet and wound in such a way that the resultant voltage induced by relative axial movement is zero. As shown (Fig. 3), the cylindrical permanent magnet 1 with diametrically located poles, and a coaxial soft iron cylinder 3 are both bolted to the flange of a shaft 4. Located in the gap between them is a coil 5, 5<SP>1</SP> wound in such a manner (Fig. 2, not shown) that relative axial movement between the magnet and the coil produces no resultant induced voltage in the coil. The coil is wound on a grooved former 22 attached to the magnet 1 at one end by a resilient member 20, and spaced from the magnet by bronze bearing rings 23. To prevent excessive relative movement the rotating flanges carry pins 32 which project into slots in the former 22.
