Title: Improvements in and relating to article advancing mechanism for slicing machines
IPC: B26D7/06
Filed: 1935-10-11
Abstract: 454,051. Endless chain conveyers. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. Oct. 11, 1935, No. 28098. Convention date, July 26. [Class 78 (i)] [See also Group VI] In a slicing-machine wherein the loaves or other articles are advanced in a train, towards and past the slicing-means, each loaf is engaged between a pusher 11 and a plate 14 attached to conveyer chains 13, 16 respectively. Since the loaves of a batch are not all exactly of the same length, it is necessary that means should be provided for ensuring that the loaves are pressed, during the beginning of the slicing, against the plates 14, to ensure that the first slice cut is of correct thickness The members 12 carrying the pushers 11 are, therefore, provided with rearwardly extending arms 22 carrying rollers 23 which run between guides 24, 26, 30 and 25, 27, 31. The members 12 are connected to the chain 13 and are themselves guided by rollers 17 running in a guide rail 20. The guides 30, 31 are connected to the guides 24, 25, which are fixed, by guide sections 26, 27 pivoted at 28, 29, 32, 33 to the guides 24, 30, 25, 31. The guides 30, 31 are joined by cross-pieces 34, 35, the cross-pieces being connected to parallel levers 38, 39 angularly adjustable by a handle 43 which is locked in its adjusted position by a screw 45. Depression of the handle raises the guides 30, 31 which tilts the pushers 11 to press the forward ends of the loaves against the plates 14. As the slicing progresses, the pushers are restored to vertical positions. The chains 13, 16 are relatively adjustable lengthwise to adjust the distance between the plates 11, 14 to correspond with the maximum length of the loaves to be sliced. The tilting of the pushers will then close the gaps in the case of short loaves, and the comprossibility of the loaves will permit the tilting in the case of long loaves. The members 15 carrying the plates 14 are guided by rollers 18, 19 engaging a guide rail 21. Specification 429,713, [Group VI]. is referred to.
Patent GB-907478-A (GB)
Title: Improvements in or relating to apparatus for use in the zone-by-zone melting of a rod of fusible material
IPC: C30B13/28
Filed: 1959-08-17
Abstract: In the treatment of a fusible rod by the passage of a molten zone through the rod while one end is maintained stationary and the other end is rotated, formation of the molten zone is effected while a torque is applied to the first mentioned end and the second mentioned end is held stationary.  Rotation of the first mentioned end takes place on formation of the molten zone and is used to detect such formation.  Rotation may be delayed by the use of an oil damping device.  The torque may be produced by a spring or by <PICT:0907478/III/1> <PICT:0907478/III/2> the coaction of a current-carrying coil and a permanent magnet. Solidification of the molten zone may be detected by rotation of the first mentioned end. As shown in Fig. 1 a rod holder 9 depends into a vacuum vessel 2 from a rotatable mounting in a cap 3 and is engaged by a magnetic clutch with an inverted U-shaped member 13 which is rotatably mounted on cap 3.  The magnetic clutch is constituted by a pair of soft iron armatures 11 forming part of holder 9 and a pair of bar magnets 12 forming part of member 13.  A torque is produced by a coil 20 and a permanent magnet 19 in member 13 and is transmitted by the magnetic clutch to holder 9.  Formation of the molten zone, the lower holder (not shown) being stationary, causes rotation of the holder 9 and member 13 until a pin 24 on member 13 contacts a stop 23 on cap 3. Such a contact may produce an electrical signal.  A second stop 23 enables to and fro movement a number of times to provide a delay before the signal is given.  Initial delay may be provided by an oil damping device comprising vanes 17 attached to member 13 and rotating in an oil bath 3A.  Solidification of the molten zone while the lower holder is being rotated breaks the magnetic clutch and causes rotation of the holder 9 only, thereby bringing one of the soft iron armatures adjacent a bar magnet 28 (Fig. 2) which moves so as to produce a signal or disconnect a circuit.

Abstract: A process for treating alkali-metal phosphate-modified starch and separating therefrom an alkali-metal phosphate-modified starch fraction of increased viscosity when dispersed in water, said modified starch having been obtained by heating starch with an alkali-metal orthophosphate at a temperature between 120 DEG  and 175 DEG  C., comprises dispersing said alkali-metal phosphate-modified starch in a proportion between 10 and 20% by weight or higher up to saturation level, in an aqueous solution containing between 30 and 50 volume per cent of an inert oxygen-containing water-miscible organic liquid, at 30-70 DEG  C., but below the gelatinization temperature; adding to the dispersion a sufficient quantity of the same organic liquid to precipitate an alkali-metal phosphate-modified starch fraction of substantially higher viscosity on aqueous dispersion than the original material while retaining unbound inorganic salts and lower viscosity material in the dispersed state; cooling the mixture, while agitating it, to a temperature of -25 DEG  to 25 DEG  C.; separating the precipitate from the cooled slurry; washing the precipitate at -20 DEG  to 25 DEG  c. with aqueous solutions containing higher volume per cent concentrations of the above organic liquid, and finally washing the precipitate with the above organic liquid in dry form at room temperature. The organic liquid may be one of those disclosed in Specification 998,775. In a preferred embodiment, the phosphate-modified starch has been obtained by soaking starch in an aqueous solution of alkali-metal orthophosphate, removing the liquid phase, drying the starch to a water content of below 15%, and heating the starch to 130-170 DEG C. for 1-15 hours, as disclosed in Specifications 812,363 and 812,339, the organic liquid in which the starch is dispersed is a monohydric aliphatic alcohol, e.g. methanol or ethanol, the quantity of alcohol added to the dispersion to precipitate the starch raises the concentration of alcohol in the dispersing liquid by about 10%, and the precipitated starch is washed with aqueous alcohol containing 50-80 volume per cent alcohol, then with 60-80 volume per cent alcohol, and finally with dry alcohol. During the cooling step, chlorine gas may be bubbled through the dispersion to bleach the modified starch. The alkali-metal phosphate modified starch fraction obtained may have a viscosity of 50,000-100,000 centipoises measured in 5% aqueous solution at 25 DEG  C. Specifications 857,868 and 998,327 also are referred to.
