Title: Improvements in method of preserving fruit and vegetable juices
IPC: A23L2/50
Filed: 1945-01-03
Abstract: The flavour, aroma and homogeneity of fruit and vegetable juices, e.g., the juice of apple, orange, pineapple, tomato or carrot, are preserved by the employment of containers which exclude light of wave-length below 4,900 , i.e., light in the green, blue, violet and ultra-violet bands, and the exclusion of all light of wave-length below 4900  from the juice while it is being extracted from the fruit or vegetable and enclosed in the containers.  Light-proof containers, e.g., cans, may be used, and during the extraction of the juice and enclosing it in the container all light may be excluded, or the extraction may be carried out in a chamber illuminated by light of wave-length between 4900  and 8000 , e.g., 6000-8000 .  After exclosure in the containers, the juice is preferably pasteurized; subsequently or alternatively the juice is maintained at a temperature of between the freezing point and 70 DEG F. for 15 hours or more.  Specification 560,714 is referred to.

Title: Improved method of setting woollen yarns or fabrics
IPC: D06M11/67
Filed: 1965-01-05
Abstract: Yarn or fabric containing or consisting of wool is set in a desired shape or dimension by treating it with a solution having a pH of 3-9 containing a swelling agent having hydrogen band breaking properties and reducing properties to swell the fibres in the yarn or fabric, the swelling being carried out for a period which is inversely proportional to the temperature and concentration of the solution and which is from 2 seconds to 24 hours, fixing the yarn or fabric in the final shape and dimension in which it is to set and then deswelling the yarn or fabric in this shape and dimension.  The swelling agent may be monoethanolamine sulphite or thiourea dioxide or it may comprise urea, guanidine, monoethanolamine, sodium thiocyanate or ammonium thiocyanate in admixture with sodium sulphite and/or bisulphite. The swelling agent may be applied as a solution in water or an organic solvent, e.g. methanol, ethanol, propanol, isopropanol, dioxane or mixtures thereof with each other or with water.  The material may be treated with the swelling solution during all of the swelling time or impregnated with the solution and then stored. After treatment with the swelling solution the yarn or fabric may be fixed in a flat, creased, pleated or imprinted state by mechanical treatment, e.g. milling, stretching, folding, mangling or embossing, the deformations being set during the deswelling step.  Deswelling may be effected at 0-100 DEG C with water, with water mixed with an acid, e.g. acetic or sulphuric acid, or with an organic solvent, e.g. methanol, petroleum, ethanol or trichlorethylene, optionally in admixture with water, the deswelling solution optionally containing a reagent increasing the cross-bridging, e.g. formaldehyde, and the deswelling agents optionally subsequently being removed by rinsing with organic solvents, e.g. petroleum, trichlorethylene, toluene, glycol or glycerol.  Alternatively deswelling may be effected by drying when the swelling agents are volatile, e.g. at 0-200 DEG C for 5 seconds to 24 hours.  Stretch fabrics may be produced by the process.

Title: Improvements in or relating to meat tenderers
IPC: A22C9/00
Filed: 1938-01-07
Abstract: 495,741. Tendering meat. NELDNER, S. W. Jan. 7, 1938, No. 542. [Class 28 (ii)] A meat-tendering apparatus comprises a standard 11 overhanging a base 10 and having a bearing in which a plunger 13 is slidable, a cutter head rotatably mounted on the plunger, and a stripper 42 arranged automatically to strip the meat from the knives when the plunger is raised. The plunger is actuated by a cranked lever 15 pivoted at 22 to the plunger and having a fulcrum pin 23 slidable in slots 24 in the standard. An oil cup 16 feeds a lubricating pad 19 and a passage 18 oils the pivot 22. A spring detent 73 engages in a hole 74 in the plunger which can thus be retained in its upper position. The detent is rendered inoperative by pulling it back and turning it to a locked position. The knives 30 are carried by a plate 27 which is received in a flanged plate 25 and secured thereto by screws 31. The plate 25 is secured rigidly to a stud 32 which is rotatable within a socket 33 having tangential bores registering with an annular groove in the stud 32, so that, by inserting a U-shaped pin 36, the cutter assembly is rotatably secured to the plunger. The stripper plate 42 has side flanges secured to slide bars 44 to which rods 48 are anchored, these rods being slidable through brackets 46 secured by screws 47 to the plate 25. Springs 50 surrounding the rods 48 tend to keep the plate 42 against the plate 27. Arms 51 project upwardly from the bars 44 and blocks 52 are secured thereto by screws 53, these blocks co-operating, as described below, with plungers 57 slidable in recesses in arms 56 on a member 54 which is slidable on the plunger 13 and is urged upwardly by springs 61 on guide rods 62. The plungers 57 are normally projected by springs 60 so that wear plates 59 thereon rest upon the top surfaces of the blocks 52. Thus, during the raising of the plunger, the member 54 contacts with the standard and the stripper plate 42 is arrested while the knives still move upward. Pins 67 carried by the plungers 57 move in inclined slots 66 in U- shaped members 64 and in horizontal slots in the arms 56. When the lower parts of the members 64 are engaged by the ascending plate 25, the members are moved upwardly and the inclined slots move the plungers inwardly, thus freeing the plates 59 from the blocks 52 and allowing the springs 50 to restore the stripper to its normal position against the plate 27. The plate 25 is pivoted to the plunger slightly off centre, so that when the cutter assembly is turned to effect cuts at right-angles, the second rows of cuts are made between the first rows and spaced therefrom. The cutter board 39 is slidable between pins 40 carrying freely-rotating sleeves 41.

Abstract: 1345671 Conveying confectionery cakes to a packing machine ITT INDUSTRIES Inc 6 Jan 1972 [11 Jan 1971] 592/72 Heading B8A Cakes 101 are fed to a packing machine (not shown) which packages them in pairs as shown in the package 104. A conveyer system handles the cakes 101 from a single input 102 and arranges them in pairs on a conveying card 602 (Fig. 6) with their longitudinal axes perpendicular to the direction of their axes when on the conveyer 102. Also the two cakes of a pair on their associated card 602 are arranged to be in mirror image relationship. The single stream is divided into two identical streams 105. In the first section 106 of each stream, the cakes are progessively slowed down in conveying speed by an arrangement of gearing driving a succession of sections of laterally spaced endless belts (202)-(205) (Fig. 2, not shown). The cakes are turned by the action of orientating conveyers (305), (306) (Figs. 3, and 3A, not shown), operating in conjunction with a couple of flat, horizontally (laterally and longitudinally) disposed endless belts (303), (307). The cakes are turned over by a pair of co-operating inclined belts (401) (402) (Figs. 4, 4B, not shown). The cakes are then fed past a photoelectric beam provided by members 518 and 517 (Fig. 5A, not shown). This controls the drive of a series of side-by-side belts 529 with the assistance of a clutch 516 and a cam 537 operating a switch 536 to override the photoelectric beam. The belts 529 feed the cakes successively to a conveyer belt 601. The two belts 601 converge to positions adjacent respective sides of a conveyer belt 603 carrying package cards 602. Flights 604 of the belt 603 then convey cards 602 in succession, each carrying a pair of cakes 101, to a wrapping machine (not shown).

Abstract: 672,012. Stereoscopic apparatus. DUDLEY, L. P. C. J. Oct. 14, 1948 [Oct. 14, 1947], No. 650/51. Divided out of 671,916. Class 97 (i). Apparatus for projecting superposed images from a stereoscopic pair of pictures disposed in vertical or horizontal alignment, comprises a projector having a single objective, optical means for causing the projected images of said pictures to be superposed on a projection screen, said optical means being disposed sufficiently far in advance of the projection lens to prevent the formation on said screen of objectionable side images, and filters disposed in the film gate or adjacent to the optical means for imparting to the light rays from the respective pictures of each stereoscopic pair characteristics which enable the superposed images to be resolved upon being viewed through appropriate resolving spectacles. As shown in Fig. 6, a film having left and right-eye images L1, R1 disposed thereon as in Fig. 3 is fed through the film gate of a projector and light therefrom passes through the projection lens 7, polarizers 8, 10 and a bi-prism 9, 11 on to a screen 12. Adjacent the latter is a mask (not shown) for obscuring the light from that part of the film 3 which does not bear the pictures. Polarizers 8, 10 may be replaced by complementary colour filters and instead of passing through a bi-prism, the light may be reflected vertically by a plane mirror on to two plane mirrors which are hinged together so that the angle therebetween may be varied and which reflect the light in a direction substantially parallel to that in which it leaves the lens 7. A bi-prism and filters 8. 10 may be carried by a support pivoted between brackets secured to the base of the projector so that they can be lowered out of the light path when it is desired to project non-stereoscopic pictures.

Abstract: 433,370. Controlling dynamo-electric machines ; windings for dynamo-electric machines. SIEMENS - SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Jan. 9, 1934, Nos. 847 and 848. Convention dates, Jan. 9, 1933. [Class 35] A pole-changing stator winding for a synchronous machine is made by winding the stator to give a number of poles intermediate between those required, dividing this winding in each phase into a number of sections equal to the phase number or a multiple thereof, and furnishing these sections with terminals so that they can be recombined to give the pole munbers required. A 36-slot winding for five poles, divided into in each phase into three sections and recombined to give four or six poles and a 27-slot winding with similar divisions are described. To allow of corresponding charges in the rotor winding it is made in two groups of conductors so arranged that by reversing one of them the number of poles is changed. The Figure shows such a construction to give 10 or 12 poles. In the two uppermost lines the full and dotted portions represent the portions of the circumference which have a different polarity in the two cases respectively, so that by reversing the portions which differ in the two lines, indicated in the third, the required change is effected. This can be done by dividing the winding into two portions distinguished by full and dotted lines in the fourth line of the figure and reversing the portion indicated by dotted lines. By forming the winding in two or more layers and slightly displacing one layer relatively to the other harmonics can be suppressed.
