Title: Improved method of, and means for, controlling the operation of copy machine tools or copy producing devices
Inventor: LUND JOHN
Filed: 1951-09-11
Abstract: 741,414. Fluid-pressure servomotor-control systems. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd. Sept. 1, 1952 [Sept. 11, 1951], No. 21374/51. Class 135. In apparatus for accurately controlling the movements of a copy machine tool in accordance with movements of the pattern and comprising a servo control valve responsive to the movements of the pattern to control the flow of pressure liquid to and from a double-acting servomotor operating the copy machine tool, the valve includes dither means for removing or reducing the effects of sticking and/or friction in the apparatus. As shown, a stylus 8, Fig. 1, mounted in a part-spherical bearing 9, to permit of slight rocking movement as well as axial movement, is engaged by a pattern 3 mounted on a table 60 carrying the workpiece 61. The stylus engages, through a ball 10, a ported sleeve 6 slidably mounted in a casing 5, and slidably mounting a piston valve member 7 which is continuously reciprocated by a cam 52 or by a solenoid energized by an alternating current. Liquid from a tank 27 is supplied by a pump 28 to a casing port 15 and on e.g. upward movement of the pattern through movement of the table 60 from right to left, the sleeve 6 moves upwardly to connect the upperside of the piston 22 of a servomotor 21 to pressure liquid supply and its underside to exhaust to move the table downwardly and the cutting tool 62 to reproduce the pattern profile on the workpiece 61. In a modification, a sleeve 6a, Fig. 2, is continuously reciprocated through a cam 43 driven, e.g. by an electric motor, and a pivoted lever 44 and a piston valve member 7b is operable by the pattern 3 to supply and exhaust pressure liquid to and from a pair of cylinders 50, 51 housing pistons 52, 53 engageable with levers 45, 45a which control the movements of a further piston valve member 54 controlling the supply and exhaust of pressure liquid to and from the servomotor 21. The lever 45 is connected to the lever 44 so that movements of the sleeve 6a by the cam 43 are counteracted and the sleeve 6a follows the movements of the valve member 7b. Instead of the ported sleeve or valve member being continuously reciprocated either of them may be given a continuous rotary movement and have ports to cause continuous opening and closing of communication between the valve member and sleeve.

Title: Improvements in or relating to the production of insolubilised protein-artificial filamentary products
IPC: D01F4/00
Filed: 1945-08-22
Abstract: A process for the insolubilisation of artificial filamentary products obtained by spinning aqueous alkaline solutions of vegetable globulins or phospho-proteins into suitable acidified saline coagulating baths, comprises treatment first in a bath of aqueous formaldehyde, saturated with both sodium chloride and sodium sulphate or with both sodium chloride and magnesium sulphate at a pH of 4 to 6 and at a temperature not exceeding 60 DEG  C., and second, in a bath of aqueous formaldehyde strongly acidified with sulphuric acid and saturated with either sodium sulphate or magnesium sulphate at a raised temperature. Preferentially, if the first formaldehyde bath is saturated to both sodium chloride and sodium sulphate the second strongly acidified bath is saturated to sodium sulphate while if the first is saturated to both sodium chloride and magnesium sulphate the second is saturated to magnesium sulphate.  The filaments may be prepared from solutions of pea-nut proteins or of casein.  The time of treatment in the bath at pH 4 to 6 is dependent upon the temperature; at 50 DEG  C. about five minutes is sufficient whereas at 40 DEG  C. 8-15 minutes will be necessary.  This bath must be saturated in order to employ the second strongly acid bath at a temperature sufficiently high to effect rapid insolubilisation. The second bath should not be at a temperature higher than 75 DEG  C. The time of treatment at 70 DEG  C. is 10 to 15 minutes.  The concentration of sulphuric acid is at least 175 g. per litre. The concentration of formaldehyde in both baths is of the order of 1 1/2 per cent.  In an example stable fibre produced from unhardened protein artificial filaments made by spinning an aged solution of pea-nut protein in dilute sodium hydroxide into strong sodium sulphate acidified with sulphuric acid at 30 DEG  C. is immersed in a warm solution containing 1 1/2 per cent formaldehyde by weight and saturated to sodium chloride and sodium sulphate and brought to pH 5.0, the temperature of the bath being 50 DEG  C.  After 5 minutes the fibre was removed and allowed to drain somewhat.  It was then transferred to a second bath at 70 DEG  C., a bath saturated to sodium sulphate at that temperature and containing 1 1/2 per cent formaldehyde by weight and a sulphuric acid content of 240 g. per litre.  After 10 minutes treatment it was removed and washed and it was found to be unimpaired by boiling with water or by acid wool dye baths. Finishing treatments were then given.  Specification 513,910 is referred to.

Title: Improvements in or relating to filtering apparatus
Inventor: FREELAND WILLIAM
IPC: B01D29/09
Filed: 1965-05-21
Abstract: 1,128,061. Filters for liquids. M.E.L. EQUIPMENT, CO. Ltd. 14 April, 1966 [21 May, 1965], No. 21618/65. Heading B1D. In apparatus of the kind in which filtration occurs through a portion of a strip of filter medium located over a perforate portion of a tank bottom, and the strip is moved automatically on attainment of a predetermined level of unfiltered liquid owing to accumulation of residue upon the strip, the filtrate is received in a suction chamber beneath the tank; preferably there is included a valve, operated by a solenoid in the controlling electric circuit, for relieving the vacuum normally existing in the suction chamber. This valve is opened to admit liquid (e.g. filtered liquid) or air to the suction chamber during a specified interval before the filter-medium operating mechanism is started, so that movement of the medium is not impeded. As shown, paper, cloth or the like 6 from a roll 7 is located by conveyer 11 having transverse flight bars (not shown) on a perforated plate 4 at the bottom of a tank 1. Suction is applied to a chamber 3 by a centrifugal pump 5. When a float-operated switch 26 is closed by rise of liquid level, the following sequence takes place: (a) the vacuumrelieving valve (not shown) is opened and pump 5 is stooped; (b) after a delay of, e.g., three seconds a motor 18, driving conveyer 11 and rollers 9, 10 and 23, is started, to remove and replace the soiled portion of strip 6 on plate 4; (c) after a predetermined time, e.g. 7 seconds, the vacuum-relieving valve is closed, the conveyer is stopped and pump 5 restarted; (d) switch 26 opens, restoring the circuit to its normal condition. In the filtration of high-viscosity liquids, the vacuum-relieving valve admits liquid from a filtrate tank 2. In the filtration of lowviscosity liquids, pump 5 remains in operation while the valve admits filtrate from tank 2, when a continuous supply of clean liquid is required. Where an intermittent supply of low-viscosity liquid is permissible, pump 5 is stopped and the valve admits air. The float-operated switch may be replaced by a pressure-operated switch or by a relay device operated by one electrode and the tank or by two electrodes.

Abstract: 1534474 Pyrolysis of carbonaceous materials OCCIDENTAL PETROLEUM CORP 24 May 1977 [25 June 1976] 21933/77 Heading C5E A process for the pyrolysis of carbonaceous materials, comprises forming a high velocity stream of carbonaceous material to be pyrolyzed and a particulate solid source of heat at a temperature above the pyrolysis temperature and introducing said stream through a tangential inlet 10 to a cyclone reaction-separation zone 12 wherein the carbonaceous material in said stream is pyrolyzed by heat transfer from the particulate solid source of heat in an amount sufficient for the carbonaceous material to attain a pyrolysis temperature of at least about 315 C. to yield a pyrolytic vapour containing both condensible and non-condensible hydrocarbons and a carboncontaining solid residue, while concurrently the particulate solid source of heat and carboncontaining solid residue of pyrolysis are centrifugally separated from the pyrolytic vapour; removing the centrifugally-separated pyrolytic vapour from a vapour outlet 18 at one end of the said cyclone reaction-separation zone, and cooling the removed pyrolytic vapour to condense hydrocarbons therefrom; removing a mixture of particulate solid source of heat and carbon-containing solid residue of pyrolysis from a solids outlet of said cyclone-reaction zone at an end thereof opposite said vapour outlet 18; and passing at least a portion of the said removed mixture to a combustion zone 14 to combust carbon therein in the presence of free oxygen thereby to form particulate solid source of heat at a required temperature for introduction to the cyclone reaction-separation zone 12. As shown in the Figure, the carbonaceous feed, which may be coal, waste, tar sands, shale or hydrocarbon oils is preferably mixed with a non-reactive oxygen-free carrier gas. The carrier gas may be flue gases from zone 14, off gases from the process (exiting from line 26), nitrogen, or hydrogen. The gases leaving by outlet 18 contain carrier gas, flue gases and the vapourised pyrolysis products, and are quenched at 20 to condense the hydrocarbons contained, the quench effluent passing to a fractionating toner 22. The hydrocarbons separated as middle distillate leave from line 28 and contain gasoline, diesel and heating fuel components. The heavy hydrocarbon residue is split and a portion 17 returned to the scrubber, a portion 24 used as quench oil, a portion 15 recycled to reaction zone 12, and the balance 19 recovered as a heavy oil product. Fig 2 (not shown) illustrates a system in which the quench oil is externally supplied and is immiscible with the product oil.

Abstract: 1,107,081. Rotary-piston internal combustion engines. REGIE NATIONALE DES USINES RENAULT. May 24, 1965 [May 29, 1964], No.21991/65. Heading F1F. A rotary-piston diesel engine of the kind comprising an n-lobed piston 3, Fig. 1, of epicycloidal contour eccentrically revolving in a stator having n + 1 lobes to provide n + 1 working chambers, includes with each working chamber a cylindrical cross-section combustion chamber 9 extending the full axial length of the piston, an air inlet valve 18 and an exhaust valve 19. As the piston 3 rotates in the direction of the arrow 4, the centre of gravity of the volume of each working chamber moves in the direction of the arrows 7 so that during one revolution of the piston this centre of gravity moves in the direction of the arrow 8 opposite to that of piston rotation to create a two-dimensional turbulence throughout the entire length of the working chamber. At the same time air in the combustion chamber rotates in the direction of the arrow 11 opposite to the direction 8 to create further turbulence. The inlet duct 21 controlled by the valve 18 is positioned with its axial plane coincident with the mid transverse plane of the piston at a small angle to the working chamber so that the air is directed into the working chamber perpendicular to the engine axis in a direction opposite to that of piston rotation to create still further turbulence. Fuel injectors, one or two, are mounted for symmetrical injection of fuel into each combustion chamber. A starting glow-plug is fitted in each combustion chamber. To preserve a high operating temperature the combustion chamber may be fitted with a liner which except for a small distance adjacent the mouth of the chamber is free from contact with the surface of the chamber. Bolts connecting the end portions of the stator to the central portion may be regularly spaced around the stator close to its curved contour to provide effective gas-tight seals. The combustion chamber may be located upstream of, downstream of or between the valves 18, 19.
