Title: Improvements in and relating to the manufacture of metal articles of different thicknesses
Inventor: JACKSON SIDNEY HARDCASTLE
IPC: B21D53/62
Filed: 1957-03-14
Abstract: 883,022. Making spoons and forks. FIRTHVICKERS STAINLESS STEELS Ltd. June 12, 1958 [March 14, 1957], No. 8528/57. Class 83 (2). [Also in Group XXIII] In a method of making articles e.g. spoons and forks, of corrosion-resisting steel and having a length of greater width or area and lesser thickness than an adjoining length, the respective lengths are produced separately as preformed simple blanks which are then welded together to form composite blanks or alternatively composite blanks are punched directly from sheets or strips which have been welded together edge-to-edge, the welded joints afterwards being trimmed and the composite blanks subjected to mechanical working to the final shape. A spoon blank, Figs. 1 and 2, of austenitic steel is formed by welding together a handle blank 10, punched from rolled strip, and a blank 12, which may be shaped to the profile 13 of the bowl. Surplus weld metal is then removed by grinding and the composite blank is worked to final shape. The handle blank may be tapered strip and the preformed blanks 10, 12 may be polished prior to welding. In a modification composite table spoon blanks 24 are punched from a composite sheet formed by welding together a sheet 20 and two thinner strips 21, Fig. 3, the blanks 24 being subsequently stamped or pressed and polished. The composite sheet may also be formed from one thick and one thin sheet welded together. The sheet 20 or strip 21 may be polished prior to welding. In a further modification a handle blank is forged from bar stock (Fig. 7, not shown) and a sheet bowl blank is welded to it. Forks may also be formed from similar composite blanks the prongs being punched during the final shaping. Welding may be by electric resistance flash butt welding, inert gas shielded arc welding, metal arc or carbon-arc welding or atomic hydrogen welding.

Title: Improvements relating to wire coiling apparatus
Inventor: PAMPLIN JOHN WARNER
IPC: B21C47/14
Filed: 1969-02-17
Abstract: 1,253,444. Wire coiling apparatus. MARSHALL RICHARDS BARCRO Ltd. 17 Feb., 1970 [17 Feb., 1969], No. 8530/69. Heading D1T. Wire coiling apparatus comprises a dead block 6, i.e. non-rotatable in operation, a rotor device 10 mounted upstream of the block 6 for coiling wire thereon, an elongate coil carrier means 21 secured to the block 6 to receive coiled wire from the downstream end thereof and to guide the coils away from the block, first holding means mounted on the carrier means 21 and second holding means interengageable with the first holding means and mounted separately from the carrier means 21, the first and second holding means being arranged, when engaged, to hold the coil carrier means 21 and thus the block 6 against rotation under the influence of the coiling torque, the coiled wire passing between the first and second holding means in operation. The coil carrier means 21 preferably comprises plates 23, 24 arranged in cruciform configuration, and is angled to extend laterally downwards from the block 6. The ends of the plates 23, 24, may be provided with angled rods 26, 26a at the lower end of the carrier means whereby the coiled wire is deposited on a conveyor 20 with the axes of the coils vertical. The first holding means in this embodiment is in the form of a wheel 27 mounted between the rods 26, 26a at the lower end of the carrier means. The wheel 27 engages with the second holding means which in this embodiment is the conveyor 20. In operation, wire 12 passes through a hollow rotary shaft 2 and is deflected by guide 14 to a pulley 16 on the rotor device 10 which is fixed to the shaft 2. As the rotor device 10 rotates, wire is wound on the stationary block 6, the coiling torque tending to rotate the block 6. The coils of wire pass from the end of the block 6 to the coil carrier means 21 and slide down the carrier means to be deposited on the conveyor 20. The coiling torque tending to rotate the block 6 also tends to rotate the carrier means 21 and forces it down towards the conveyor where the engagement between the wheel 27 and the conveyor arrests the rotation of the carrier and thus the block 6. As the conveyor 20 moves to carry the coils away, the wheel 27 rides over the coils on the conveyor. The wheel may be adjustable in position to allow for different angles of the conveyor relative to the axis of the apparatus. In a further embodiment, the first holding means is in the form of a roller on one of the plates of the carrier means, and the second holding means is in the form of a roller mounted on the machine frame, the interengagement of the rollers arresting the rotary movement of the carrier means and thus the block. The coils of wire pass between the two rollers as the coils slide down the carrier means.

Title: Improvements in or relating to photographic roll film cameras
IPC: G03B19/04
Filed: 1934-03-23
Abstract: 435,468. Magazine hand cameras for roll films. KODAK, Ltd., Kingsway, London.- (Eastman Kodak Co.; 343, State Street, Rochester, New York, U.S.A.) March 23, 1934, No. 9103. [Class 98 (i)] To ensure accurate registration of the exposure areas of a roll film a camera which has a body portion 1 and detachable back 2 comprises an exposure frame, mechanism for winding the film-which comprises a sensitive strip 45 having openings 47 longitudinally spaced apart therein at intervals corresponding to the length of one exposure area and a backing strip 46 for the sensitive strip-from a supply chamber on the exposure frame to a take-up chamber, a feeler member 18 resiliently pressed against the sensitive strip so as to register successively with the openings therein and a separating device 40 adapted to pass between the sensitive strip and backing strip adjacent to the feeler member and to separate them to permit the feeler member to pass through each opening. The film is wound by a key 8 furnished with a spindle 9 carrying a web 11 adapted to engage a slot in the take-up spool, and also a ratchet wheel 12 arranged to cooperate with the nose 13 of a locking member 14 fitted on the end of a lever 17 carrying the feeler member 18. The other end of the lever 17 is engaged by a spring finger 22 when the back of the camera is in position. The lever 17 may be depressed against the action of the finger 22 bv a hand actuated release stud 23 on the back 2 of the camera. The back also carries projecting members 26, 27, to retain the trunnions on the ends of the spools in place and a spring mounted presser plate 34 which is provided with an opening 41. A separating finger 40 extending from the side of the opening is directed towards the exposure frame and is formed with an aperture 42 registering with the feeler member 18 when the back is in position. The backing strip 46 of the film is provided with a slot 49 in that edge adjacent to the apertures 47 in the strip 45. When the film has been inserted and the back placed in position the winding key is rotated and as the film passes towards the take-up chamber a rib 33 on the film guide 32 bends the material into the plane of the separating finger 40 so that this finger readily passes through the slot 49 and enters between the sensitive and the backing strips : continued movement of the film thus causes the backing strip to be raised from the sensitive strip in the vicinity of the finger so that when the first perforation 47 in the sensitive film comes into register with the feeler member 18 this member passes therethrough and simultaneously the member 14 locks the winding device. After the exposure has been made the winding device is freed and the member 18 depressed by the release stud 23. A slit may replace the open slot 49 in the film or the end of the sensitive strip may be given a Z-fold, a slit being made in the rear angle of the Z; in this case the rib 33 may be omitted from the camera. Specifications 435,467 and 435,519 are referred to.

Patent GB-353413-A (GB)
Title: Improvements in and relating to the manufacture of aldols
IPC: C07C45/72
Filed: 1930-03-21
Abstract: Aldehydes are condensed to aldols in the presence of normal sodium carbonate in excess in the solid phase throughout the reaction and of free water controlled in quantity so as to limit the quantity of water to 25 per cent by weight of the anhydrous sodium carbonate. The water may be supplied by using aldehyde containing water, by using sodium carbonate carrying extraneous water, or by using the aldol-containing liquid from a previous operation.  By reducing the quantity of free water used, the reaction is retarded; for instance, if the amount of water present is 5 per cent by weight of the soda-ash, the reaction still proceeds, but at a slow rate.  The process may be operated continuously or "batchwise," and the quantity of catalyst taken should be of the order of the weight of aldol to be produced in 24 hours.  The reaction may be conducted in an inert oxygen-free atmosphere.  The proportion of liquid admixed with the soda-ash or the like may be sufficient to render the reaction mixture fluid and easily stirrable, or the mixture may contain so much solid that the liquid merely percolates through or is forced through as in a filter press.  In another mode of carrying out the process, acetaldehyde is distilled on to soda-ash mixed with liquid from a previous operation, the mixture being stirred and the temperature controlled in order to maintain the desired speed of reaction. The aldol and unchanged aldehyde are subsequently separated by distillation.  In the examples, (1) 100 parts by weight of anhydrous commercial soda-ash are treated in a closed vessel with 130 parts of anhydrous acetaldehyde and 17 parts of water at a temperature below 15 DEG  C.  The mass is stirred for 5 hours, and 78 parts of 96 per cent aldol are obtained by extraction with a solvent, such as benzene, and distillation.  (2) 100 parts by weight of commercial soda-ash are placed in a suitable closed vessel, and acetaldehyde containing 5 per cent of water is slowly and continuously introduced for a period of about 24 hours.  The issuing liquid is led to a continuous concentrator heated to 100 DEG  C. whereby the unchanged aldehyde is removed and returned to the vessel after adjusting the water content to 5 per cent.  In 24 hours, 100 parts of aldol are produced.
