Title: Improvements in or relating to the manufacture of artificial protein filaments
IPC: D01F4/00
Filed: 1943-10-20
Abstract: Filaments obtained by wet-spinning from solutions of casein or vegetable globulins are subjected to an insolubilizing treatment to such an extent that they are resistant to the action of hot weakly acid or alkaline solutions, and are then subjected to wet-stretching, and while in the stretched condition they are subjected to raised temperature and to treatment with formaldehyde, and thereafter the tension is removed and the filaments are caused to shrink until they have become crimped to the desired extent.  The filaments have a wool-like appearance and high tensile strength.  The wet-stretched filaments may be dried under tension at raised temperature before the formaldehyde treatment is commenced.  Drying is effected at a temperature of not less than 80 DEG  C.  The filaments may be further heated to a temperature of 100-120 DEG  C. before commencing the formaldehyde treatment.  Wet-stretching may be carried out in presence of hot water or steam.  The stretched filaments may be immersed in commercial formalin solution, i.e. a solution of formaldehyde of lower acidity than that used in the previous insolubilization step, and left in contact with the solution for several hours at ordinary temperature.  Alternatively, the filaments may be treated with formaldehyde vapour.  After the treatment with formaldehyde, the filaments are washed and then dried at a temperature not below 80 DEG  C. and they may be further heated.  At this stage the filaments are straight and silk-like when the tension is released, but on immersion in hot water they shrink and after drying in untensioned condition they have a wool-like crimp.  In an example, filaments obtained from a solution of peanut protein in aqueous caustic soda solution by coagulation in a hot acidified sodium sulphate bath are insolubilized in untensioned condition in a solution of sodium chloride containing formaldehyde and sulphuric acid.  The filaments are washed with water containing a wetting agent, and then with dilute sodium carbonate solution. They are dried in hot air and then stretched in wet steam and wound helically on a roller.  The roller is placed in a solution of formalin for several hours.  The filaments are washed and then dried under tension in hot air.  After winding into hanks the filaments are immersed in boiling water in untensioned condition, and then dried.

Title: Improvements in honing and lapping machines
IPC: B24B33/02
Filed: 1943-10-20
Abstract: 568,244. Honing and lapping. WINDSOR, R. H., and CASPAR, E. Oct. 20, 1943, No. 17259. [Class 60] A honing machine operated by hydraulic means or by compressed air, comprises a base 10, in which are formed an oil tank and a suds tank, oil being delivered to a cylinder 15 by a pump 14, and suds delivered to the work 22, which is mounted on a table 23, by a pump 25 and pipe 24. On the base 10 are mounted three tiebars 29, 30, 37, the front two 29, 30 carrying the table 23, which is adjustable for height, and also two brackets 31, 32 supporting, in bearings 35, 36, the shaft 33 carrying the honing-head 34. The upper bracket 31 is connected also to the rear tie-bar 37, and carries an electric motor 38 driving, by belt 39 and stepped pulleys, the shaft 33. On the bar 37 is fixed a piston 41 located in the cylinder 15, which is movable and has thereon a bracket 42 carrying a thrust bearing 43 for imparting axial movements to the shaft 33. Inside the tie-bar 37 is an annular channel 44 communicating at its upper end with a pipe 45, 55 leading to a change-over valve 18, and at its lower end, through a port 46, with the cylinder 15 above the piston 41 ; a tube 47 is situated in the channel 44 leading, by passage 49 and port 50, to the space 48 below the piston. The changeover valve 18 is of the piston type, and is actuated by a pilot valve 52 having an operating-lever 53 movable to reverse the connections of pipes 54, 56, leading to opposite ends of the change-over valve, to pipes 117, 121 connected to pressure and return pipes 17, 21 ; movement of the pilot valve normally is effected by dogs 57, 58 adjustably mounted on a rod 59 mounted on the cylinder 15, so as to reverse the direction of movement thereof at the ends of the strokes, whilst manual operation may be employed by movement of a hand lever 60, the dogs being turned on the rod 59 to a position where they do not engage the lever 53. Joining the brackets 31, 32 is a threaded rod 61 carrying two adjustable stops 62, 63 which co-operate with an abutment 64 on the bracket 42 should the change-over fail to operate, a relief valve 19 then opening to permit return of oil to the tank. In order that the weight of the moving parts may not cause higher speed on the down strokes, a compensating valve 65 is included between the pipes 45, 55 ; this valve has a spring-controlled ball which inserts a resistance in the exhaust on the downstroke, and a byepass valve for pressure fluid on the upstroke. A stop and speed control valve 72 also is provided in the pipe 21 operable by a handle 73, and also is effective as an emergency stop. The machine may be employed for lapping by replacement of the honing head by a lap and adjustment of the rotary and reciprocatory speeds.

Title: Cane disintegrator
IPC: C13B5/04
Filed: 1966-04-20
Abstract: 1,138,081. Sugar cane disintegrator. J. C. V DUCASSE. 18 July, 1967 [20 April, 1966], No. 17376/66. Heading A4C. A machine for simultaneously cutting and shredding sugar cane or other plant products comprises a rotor D, made of a series of plate steel discs mounted on a shaft H across the head end of a feeding conveyer or carrier J, on the periphery of which and between the discs are pivotally attached four U-shaped blades C, spaced at 90 degrees apart circumferentially, the legs of which are so arranged to provide four intermediate spaces in which are fixed two straight knives E so disposed that they rotate in different co-axial cutting planes. The blades C have cutting edges formed by the two limbs and the bridge of the U, and each blade carries on the bridge portion six triangular hammers F. In use the swinging blades C assume a radial position but on encountering the ends of the massed cane fed in a direction substantially perpendicular to the axis of rotation of the rotor by carrier J are thrown back thus exposing the straight fixed knives E which make a series of longitudinal cuts in the canes while the blades C make transverse cuts in them. The knifed canes are scattered over an adjustable steep shoot A, and then slide down on to anvil bars or an adjustable hinged gate G, which is yieldable biased towards the rotor D by counterweight means or by spring means N encircling an adjustable rod K so that any "tramp iron" entering the machine forces the gate back, thereby preventing serious damage to the machine. The inside face of G has an indented lining B, the serrations of which when the gate is in its innermost position are located at a small clearance distance from the tips of the revolving hammers F, which shred the cane chips. The resulting disintegrated cane leaves through an outlet 2 at the bottom of the machine and is deposited on a suitable discharge conveyer M.

Filed: 1976-04-29
Abstract: 1523983 Electrode replacement and slime removal in electrowinning ONAHAMA SEIREN KK 29 April 1976 17470/76 Heading C7B Anode and cathode sheets in electrowinning, each suspended in a parallel alternating vertical array, are conveyed as follows, to and from a parallel series of rows of cells. The array is conveyed to a starting point and from thence to a desired cell by a hoist mounted for movement along a travelling bridge which spans the series of cells and travels on rails mounted level with the tops of the cells. The hoist is also used to remove electrodes and convey them to a removal point. As described, the anode and cathode sheets are set up as independent parallel arrays suspended from parallel chain conveyers, and a second hoist collects each set to form the alternating array and conveys this to a truck which travels on rails alongside the cells for conveying the array to the hoist of the bridge. A second truck on rails and a further hoist may be provided enabling independent supply and removal operations. Slime removal A truck mounted for reciprocation along the length of the bridge referred to above has an extensible suction pipe which is moved along the base of the cell while hot water is discharged at the cell bottom at its edges from pipes movable with the suction pipe. Slime thus removed is discharged into a channel on the bridge which itself discharges into a fixed trough alongside the cells.

Title: Analysis and representation of the size shape and orientation characteristics of the components of a system
IPC: G02B27/46
Filed: 1971-05-27
Abstract: 1356467 Diffraction systems J H TALBOT 27 May 1971 [29 May 1970 23 Nov 1970] 17662/71 Heading G2J [Also in Division G1] In analyzing the goemetrical characteristics of components of a system 17, such as in tissue matching or controlling the quality of a mill product having particles suspended in a liquid, the system 17 is illuminated with coherent light 12, to form the far-field diffraction pattern 25 which is variably attenuated outwards from the centre according to a rational power of the distance from the centre. The attenuation may be performed by a filter 24 and the output produced on a viewing screen Fig. 2, (not shown) graduated to give a read-out of the desired parameter. Different filters are so designed as to provide information concerning the number of components of the system, their linear dimensions, their specific surface area or their mean volume. The information may be detected photo-electrically. In one embodiment a system in a flow cell 50 Fig. 4 is illuminated with coherent light 12. The diffraction pattern is split by beam splitter 56 to form on two photo-cells 57, 58, each having a filter 65, 66. The outputs are amplified at 67, 74, rectified and integrated at 68, 73 and the signal from integrator 73 converted to digital form at 72. Integrated signal 68 is compared at 69 to reference signal 70; and when it equals this it gives the command to digital printer 71 to print the integral registered by integrator 73. Since the integral registered on integrator 68 is a constant set by the reference voltage 70 this integral is used in effect as a constant denominator and thus the information printed out represents the ratio of the two outputs. The output may be detected by a photocell through an annular mask movable along the optic axis of the system or by a series of annular photo-cells Fig.5 (not shown) located along the optic axis, the filtering function being effected by adjusting the gain of the output. Alternatively, Fig. 6, (not shown), it may be measured by a spring mounted photo-cell located on an arm rotated in the plane of the diffraction pattern and caused to follow a spiral scan across the pattern. Suitable optical filters are concentric dark and transparent rings having either a linear or parabolic gradient; a filter having annular sectors with circumferentially distributed dark and transparent rows with a radial parabolic gradient; a stemless four-leaf clover pattern, or a transparent cross on a dark background.

Title: Improvements in processes for the extraction of dry aromatic powders from liquids
IPC: A23L27/00
Filed: 1958-06-03
Abstract: A dry extract containing the aromas of an alcoholic beverage is obtained by adding to the beverage lactose or levulose or a mixture of them, preferably in the proportion of 1 to 5% by weight of the alcohol in the beverage, and then removing the alcohol and water to obtain the dry extract.  For the removal of the alcohol and water, the beverage may be fractionally distilled until the alcohol content is between 6 DEG  and 10 DEG , thence freeze-drying is effected at a temperature below - 30 DEG  C. and under a vacuum of at least 0.3 mm. According to an example, 2g of lactose were dissolved at 40 DEG  C. in 1 litre of 40 DEG  rum.  A fractional distillation of the resulting solution yielded 530 c.c. of 81 DEG  alcohol and 470 c.c. of a syrupy liquid, containing alcohol, water, lactose and the various aromatic substances, which was subjected to freeze-drying at -40 DEG  C. under 0.1 mm. vacuum until a dry extract was obtained. Other alcoholic beverages are mentioned.  The extract is suitable for preparing reconstituted beverages and in flavouring cakes and sweets.

Title: Improvements in or relating to fluid pressure systems
IPC: B64C25/22
Filed: 1942-12-15
Abstract: 562,144. Hydraulic control systems; valves. BENDIX AVIATION CORPORATION. Dec. 15, 1942, No. 17839. Convention date, Feb. 19. [Classes 69 (ii) and 135] [Also in Group XXXIV] In a fluid-pressure control system for operating motors for controlling brakes, clutches, throttles, &c. on automobiles, or aircraft, the pressure produced by a pump 14 is stored in an accumulator 42, but if excessive pressure is produced the pump output is byepassed to a reservoir 10 which is at atmospheric pressure. As applied for operating the motors 26, 34 of brakes 28, 36, the application of pressure to the brakes is controlled by a valve 20 and a pedal 52 which transmits pressure through a spring 102, Fig. 4, to a plunger 90 forming part of the valve system 20. When the brakes are inactive the valve system 20 is in the position shown in Fig. 4, and pressure fluid enters the valve by a pipe 16 and passes via a non-return valve 68, to a pipe 38 leading to the accumulator 42. A spring-controlled relief valve 96 opens to connect the accumulator 42 to the reservoir 10 at a given pressure. The brake motors are connected by pipes 24, 32 to a chamber 110 of valve 20 and, as shown in Fig. 4, this chamber is connected by the member 104b of a valve 104 to the reservoir 10 so that the motors are not under pressure. Another valve member 104a is closed and cuts off communication of the chamber 110 with the accumulator. At a given pressure, the accumulator 42 is byepassed by the motion of a small piston 86 which normally closes a byepass passage 84 leading to the reservoir 10. The motion of piston 86 is opposed by a larger piston 126 which is acted upon by a pressure equal to that of the chamber 110. As shown in Fig. 3, the motion of piston 126 is opposed by links 128 associated with spring-pressed pistons 130 so as to act with a toggle action, and also with a snap action, the action being similar on reversal which occurs when the pressure builds up in the brake motors to cut out the byepass action. When the brakes are being applied the movement of plunger 90 causes the valve 104a to open and thus connects the chamber 110 and the brake motors to the accumulator 42, and the valve 104b shuts to cut off communication with the reservoir 10. Since the increased fluid pressure on the plunger 90 tends to move it backwards a reaction on feel is created.
