Title: Improvements in or relating to the production of flakes, wafers or the like from wood and woody material and to the production of moulded products therefrom
IPC: B29C65/48
Filed: 1952-04-08
Abstract: 730,017. Cutting up wood. CLARK, J. D'A. April 8, 1952, No. 8976/52. Class 145. [Also in Group V] For use in the production of moulded products from wood and a binder (see Group V) fibrous flakes or wafers are obtained by moving a piece of woody material and a cutting edge disposed substantially parallel with the grain of said material relatively towards and in contact with each other across said grain, said flake or wafer comprising a plurality of fibres closely bonded together in side-by-side relation with one another as in the starting material, and unbroken along the grain. The particles may be from 0.5 to 2.0 inches long and from 0.002 to 0.065 inches thick, the preferred wood being Douglas fir or poplar. In a preferred method, knife elements 45a (Figs. 6 and 7) are arranged cross-wise of a drum 43 so that they produce slivers 48 which are substantially of the length of the wooden blocks 30. The acute angularity of the end portions of the wafers is produced by feeding the cut slivers 48 lengthwise down an inclined shoot 49 to an auxiliary cutter 50 which is rotated by shaft 51. In a modification (Figs. 1 and 2, not shown) the blocks 30 are moved laterally by endless chains and the ends are squared by means of vertical circular saws.

Title: Process for dressing iron ores
IPC: C22B1/02
Filed: 1937-03-30
Abstract: A process for dressing iron ores containing constituents which are respectively rich and poor in iron comprises heating them in a furnace wherein heating flames are provided at a number of points distributed along the length of the furnace, the ores being caused to travel through the furnace preferably in counterflow to the heating gases generated by the flames, and the heating of the ores being carried to such an extent that on the constituents rich in iron there are formed by reduction shells of FeO on cores of Fe2O3, or by oxidation shells of Fe2O3 on cores of FeO, or by alternate reduction and oxidation a number of layers of Fe3O4 between layers of FeO and Fe2O3.  The furnace may be a rotary tube furnace, or a multi-hearth furnace provided with stirrers, and reducing or oxidizing conditions may be maintained in a part only of the furnace.  Reducing gases may be introduced through a tube mounted concentrically in the furnace and extending into a reducing zone.
Patent GB-735957-A (GB)
Title: Improvements in or relating to feeding apparatus for perforated strip material
IPC: G03B1/42
Filed: 1953-04-01
Abstract: 735,957. Kinematograph apparatus. KODAK, Ltd. April 1, 1953 [April 21, 1952], No. 9039/53. Class 97 (1). [Also in Group XVI] Feeding apparatus for perforated film comprises means for advancing the film to a predetermined station including two driving members arranged in advance of said station and driven through a differential gear train, whereby both are given additional rotations to achieve correct registration of the film at the station, in accordance with any variation in the length of the film portion between them. Fig. 1 shows the application of the invention to a film feeding arrangement, of a kind described in Specification 701,850, wherein a film is fed continuously towards a film gate 10 by a sprocket 12 and away from it by a sprocket 18, the film being fed intermittently by blasts of air applied to the lower film loop. and being tensioned back, when stationary, on to register pins 15 by air pressure applied to the upper loop. In order that there shall be a fixed number of film frames in the film path from the sprocket 12 to the film gate at any instant in the feed cycle, independently of any film shrinkage (or stretch); a correcting movement is added differentially to the movement of the sprocket 12, the shrinkage and the resulting correction being determined by the mechanism shown in Fig. 2 from the length of film stretched between the sprocket 12 and a further sprocket 20. The sprocket drive is taken through a worm 34 and worm wheel 25 to a sleeve 26 carrying planetary pinions 36, 37, meshing respectively with a gear 29 on the shaft 28 of the sprocket 12 and a gear train 31, 32, 40, 42 driving the sprocket 20, the gears 31, 32 rotating loosely on the shaft 28. The distance from the gate to the sprocket 20 is chosen to be twice that to the sprocket 12 and the gear ratios are chosen so that any rotation of the sprocket 20, when the drive is stationary and no film is threaded, produces a rotation of the sprocket 12 in the same direction and of half the amount. A brake 46 on the gear 42 tensions the film between the sprockets. The same effect may be produced by a blast of air applied to a film loop L (Fig. 1), between the sprocket 20 and a further sprocket 45 which pulls the film off the feed spool. Another embodiment is described in which the sprockets 12 and 20 are both driven intermittently by a maltese cross mechanism through a differential device similar to that described above. A retarding force is applied to the shaft of the sprocket 20 by a band-brake, the force being increased by a cam to lock the shaft while stationary. A camoperated brake may also be applied, while the film is stationary, to the margins of the film on the sprocket 20 or of the film between the sprockets.

Filed: 1935-03-23
Abstract: 454,226. Electricity supply ; starting prime-movers. GRANT, P., and RUSTON & HORNSBY, Ltd., Sheaf Iron Works, Waterside South, Lincoln. March 23, 1935, No. 9100. [Class 38 (iv)] Substituting sources in service.-Comprises a starting system for an internal-combustion engine in which the starter motor circuit is closed by a relay energized on closing starting switch through the normally closed contacts of a second relay having a time delay device and is energized so that it opens a predetermined time after initiation of starting and is maintained open during normal running. Closure of the starting switch b completes the circuit through closed relay contacts 2b, 3b of the operating winding 1a of the starting motor switch 1, and also completes the circuits of relay windings 2a, 2c and 4a. The relay 2 has a time delay opening so that a predetermined time after initiating of starting the contacts 2b open and de-energize the starting motor switch 1. If the engine starts, a time delay relay 3 energized from an auxiliary generator G opens, and de-energizes the relay windings 2a, 4a, the winding 2c being sufficient, however, to retain the relay 2 open. If the engine fails to start or during normal running stops, or the generator G fails, the relay 4 having a larger time delay than relays 2 and 3 operates to complete an alarm circuit. A further relay 5 is provided to stop the engine by means of a solenoid operated fuel byepass in response to abnormal conditions such as failure of oil pressure in the lubricating system or overheating of the cooling water. The gauge r responsive to the oil pressure may have two contacts, the first closing an alarm circuit, the second shutting the engine down. The arrangement may operate as an emergency plant, the starting switch being under the control of the current in the main circuit so that in the case of failure the switch is closed and the plant started, and the main generator switch onto the main circuit.

Patent GB-1041612-A (GB)
Title: Preparation of esters of acrylic acid
IPC: C07C69/54
Filed: 1964-03-04
Abstract: Esters of acrylic acid are obtained by decarboxylation of a mono-copper salt of a halfester of maleic or fumaric acid containing 1 atom Cu per molecule at a temperature in the range 100-290 DEG  C. and in the presence of at least 10% mol based on the half-ester of compounds having a tertiary nitrogen atom in a pyridine-type ring. The preferred esters are those derived from C1- 4 aliphatic alcohols, C4- 10 primary or secondary alcohols, cyclohexanol and benzyl alcohol.  The decarboxylation may be effected in the presence of an inert solvent, preferably the alcohol moiety of the half ester.  The mono-copper salt may be formed before or in situ during the reaction from a copper compound, e.g. cuprono oxide, and the half-ester. When formed in situ the mono-copper salt of the half-ester must be in an excess of 0.1-10 mols over the half-ester.  The reaction may be carried out in the presence of compounds having an alkaline reaction in water, e.g., KOH or CaCO3, in order to increase the conversion rate, and in the presence of one or more volatile or non-volatile polymerization inhibitors.  Examples describe the preparation of methyl, ethyl and butyl acrylates.
