Title: Plant for the treatment of bran and cereals
IPC: A21D13/02
Filed: 1935-02-11
Abstract: 456,845. Reducing grains &c. BONNER, T. W., and SALOMON, S. M., 33, St. James's Street, Pall Mall, Westminster, and BUSCH, S., 5, Chancery Lane, London. Feb. 11, 1935, Nos. 4315 and 26035. [Class 58] Grain after a preliminary cleaning is fed to a separator A, scourer B and brushing device C for further cleaning before passing, in the whole berry state, to a crushing mill D where it is reduced to a granular form in which it is readily liquid absorbing., The crushed product is deposited in a bowl E containing water where it remains for two to three hours before being carried between smooth surfaced rollers F rotating at differing speeds thus being subjected to combined compression and attrition. The bran and other cells are thus broken down and the product issues as a very thin unbroken film. This product is then taken to an ordinary dough mixer, yeast, salt, &c. added and subjected to the ordinary baking processes. Bran may be somewhat similarly treated, being rolled, sieved, rolled and dressed in a centrifugal dresser twice and then subjected to the soaking &c. treatment; the treated bran may be added to ordinary flour. The soaking may be done under pressure. Specification 382,640 is referred to.

Title: Improvements in or relating to grapnels for recovering submarine cables
Inventor: BATES OSWALD ROBERT
IPC: B63C11/50
Filed: 1955-02-14
Abstract: 791,130. Grapnels for submarine cables. POSTMASTER GENERAL. May 14, 1956 [Feb. 14, 1955], No. 4361/55. Class 113. In a submarine cable grapnel comprising a frame 1 having a central slot 2 in which slides a cable engaging member 3 having flukes 4 and normally held locked by a shear pin 21, and a cutter blade 12, the slide member 3 has mounted thereon cutter operating means comprising arms 5 slidable in recesses 6 in the slide 3 and having wedge surfaces 7 and cross arms 8 between which pulleys 9 are mounted. Ropes 13 attached to the slide 3 at 14 pass round the pulleys 9 and pulleys 15 mounted in the frame 1, and after leaving the frame at 16 are attached to a hawser. In use, a fluke 4 engages the cable which is then raised as the hawser is reeled in. When the load in the hawser reaches a predetermined value, the pin 21 shears and the slide 3 moves so that the cable C, Fig. 3, passing over the surface of the grapnel close to cable guides 17 is drawn into a channel 19. When the slide reaches the limit of its movement, as shown in Fig. 3, further loading of the hawser shears pin 25 so that the wedge surface 7 is moved up to force the cutter blade into the cable to sever it. One end of the cut cable drops away, the other being retained in the grapnel.

Abstract: 1,139,523. Cold separation of gas mixtures. PULLMAN Inc. 2 Feb., 1966, No. 4679/66. Heading F4P. [Also in Division B1] Chlorine, bromine or iodine is separated from an anhydrous gas mixture containing said halogen, the corresponding hydrogen halide and inert gas by contacting said mixture with liquid anhydrous hydrogen halide at a temperature sufficient to keep a minor proportion of said halide in liquid phase, whereby the halogen is absorbed and condensed, withdrawing gaseous hydrogen halide and inert gases, withdrawing liquid halogen-hydrogen halide mixture and evaporating a major portion of the hydrogen halide from said liquid mixture to leave liquid halogen product. The process is described in relation to the recovery of chlorine from gaseous effluents in a line 2 comprising N 2 , O 2 , CO and HCl obtained by the Deacon reaction and performed in a counter-current absorption tower 10. Part of the evaporated portion of the liquid mixture may be recycled through a line 24 to the lower part of the tower 10 to effect reboiling, the other part being recycled through lines 22, 28 to the top of the tower after liquefying at 26 by cooling or compression. The HCl gas withdrawn at 32 from the top of the tower 10 may be recovered by washing, adiabatically if desired, in a further tower with 20% aq. HCI, flashing the resultant solution, drying the gaseous HCl effluent, cooling and recycling, if desired jointly with the HCl from the liquid mixture. The initial absorption tower 10 may be indirectly cooled by means of a refrigerant liquid in a coil 12 which also may be HCl recovered in the process. Specified conditions in the initial absorption tower are - 100‹ to 0‹ C. and 50-200 p.s.i.g., the pressure being such that less than 10% of the HCI is maintained in the liquid phase.

Abstract: 1,182,352. Converting tapes and ribbons into filamentary form. IMPERIAL CHEMICAL INDUSTRIES Ltd. 12 Jan., 1968 [31 Jan., 1967], No. 4714/67. Heading B5B. Ribbons or tapes of synthetic organic thermoplastic polymeric material may be converted into coherent compressed filamentary forms by orienting the ribbon or tape by longitudinally stretching it and passing the oriented ribbon or tape without deviation from a rectilinear path through a die which surrounds and constricts the ribbon or tape, said die or said ribbon or tape being at an elevated temperature sufficient to cause the polymeric material to soften and issue from the die in a coherent compressed filamentary form. The thermoplastic material may be a polyester, a polyamide, a polyolefine or polyvinyl chloride. As shown in Fig. 1, a die comprises a pair of U-shaped half dies 1 firmly attached to rigid members 2 which are spaced apart to accommodate a sliding member 3 to which is firmly attached a third half die 4, members 2 being held in spaced parallel arrangement by end piece 5 and cross-members 6. A screw 7 passes through the end piece 5 into the end of sliding member 3 and carries an adjusting nut 8 which bears against the end piece 5 and has a scale engraved thereon. The die is positioned so that the half dies 1 and 4 are in the path of the ribbon or tape 19 at a point close to the drawing zone of the stretching machine. The die is either internally heated or positioned within means provided for heating the ribbon or tape to the stretching temperature. When passing the ribbon or tape through the stretching machine and the die the sliding member 3 is drawn to the left so as to open a gap (shown by broken lines) for the insertion of the ribbon or tape in the die, and when stretching is started the slide 3 is moved to the right by means of nut 8 until the passage of circular or elliptical cross-section through the half dies 1 and 4 is of the desired size. More than one tape or ribbon may be passed simultaneously through the constricting die, the ribbons or tapes consisting of different materials. Two tapes of different shrinkage capacity may be used and the product of filamentary form resulting from the passage of the tapes through the die may be subjected to a shrinkage treatment, whereby a bulky product is obtained.

An apparatus for inducing functioning of the heart by a form of massage, in the event of stoppage, comprises a pressure applicator which bears on the sternum. A base member 12 supports a frame 15 which carries a pneumatic ram assembly 11, the latter being conveniently powered by a compressed oxygen cylinder. The plunger 16 preferably carries a rubber cushioning member 18 and is positioned to bear on the lower portion of the sternum so that, when it is forced down, the heart is compressed and expels blood. Removal of the pressure allows the heart to expand and again fill with blood. These actions may be effected manually but are preferably controlled by an electric timing device 53 which actuates a solenoid valve 44 connected in the gas supply conduit. It is also possible to include an " augmentation " control 55 which, in the case of a faintly beating heart, receives signals from an electrocardiograph and actuates the pressure device 11 in accordance therewith to reinforce the action of the heart.
