Patent GB-1080970-A (GB)
Title: Improvements in or relating to method of manufacture of yarns from synthetic resins
IPC: D01D5/42
Filed: 1965-03-02
Abstract: Yarns, suitable for the production of fabrics, are made by extruding a fluent mixture of a synthetic resin and a particulate blowing agent in sheet or tubular form, if the latter, converting the tube into sheet form, and if required, cutting the sheet into strips or bands, orientating the extruded resinous material longitudinally until it will split easily and twisting the split material to form a yarn.  In a modification, the synthetic resin mixture is extruded in tubular form after which the tube is cut and opened out into sheet form either before or after orientation.  Specified synthetic resins include polyethylene, polypropylene, polyamides and polyesters; polypropylene is preferred.  Preferably, the particulate blowing agent is that sold under the Registered Trade Mark "Genitron". Orientation may be effected by stretching the sheet, strip or band at an elevated temperature requisite for orienting the resin.  The sheet, strip or band may be stretched up to a ratio of 11:1 in order to allow fibrillation to take place easily subsequently.  Thus orientation may be effected by passing the material through hot air or hot liquid and stretching longitudinally, suitably to a draw ratio of 11:1.  Where polypropylene is used temperatures of 280 - 300 DEG F. for hot air and 245 - 280 DEG F. for hot liquid (e.g. glycol and water) are suitable.  The thickness of the material after orientation is suitably of the order of 1 to 1 1/2 thousandths of an inch in thickness.  Yarns so made are useful as baler twine, ropes, nets and cordage.

Title: Improvements in or relating to underwater breathing equipment
IPC: B63C11/18
Filed: 1965-11-12
Abstract: Exhaled air from a diver, or in a submarine, or from other under-water enclosure, is enriched with oxygen from the surrounding sea water either by bubbling the air through sea water or by bringing the air into contact with means for extracting oxygen from the sea water, the enriched air then being conducted back to the diver &c., for breathing.  Breathing apparatus for a diver (see Figs. 1-5, not shown) comprises a device (34) which allows carbon dioxide to pass from the exhaled air into the water, oxygen to pass from the water into the air, and which prevents water from entering the breathing system, and consists of a number of parallel units (20) through which the air passes, the walls of the units comprising a thin membrane (23) of silicone rubber or microporous polyethylene which allows the permeation of the oxygen and carbon dioxide and resists water.  Each unit (20) also includes frame members (25), an inner core (21) of perforated corrugated sheet material, and reinforcing elements (22). The atmosphere in a submarine may be enriched with oxygen obtained by pumping the surrounding sea water through a similar gas exchange device.  In an underwater construction (Figure 9, not shown) having living space maintained with an atmosphere at a pressure equal to that of the outside water, the air brought into contact with the gas exchange device 65 is first reduced in pressure at a valve (69) so that the partial pressures of the nitrogen in the air and that dissolved in the water are about the same to ensure that nitrogen is not lost from the breathing circuit.

Title: Improvements relating to self-propelled traction vehicles, more particularly agricultural tractors
IPC: A01B67/00
Filed: 1964-12-03
Abstract: 1,086,662. Tractor power lift mechanism. LINDE A.G. Dec. 3, 1964 [Dec. 3, 1963; March 4, 1964], No. 48915/64. Heading A1P. [Also in Division B7] A tractor is provided with means whereby the engine output, the ratio of a continuously variable transmission gear or an operational characteristic of a mounted or trailed implement is controlled in response to the magnitude of the tractive load or to the occurrence of wheel spin. In Fig. 1 the resistance of a plough carried by a three-point linkage depresses the upper link 4 against spring loading 14 to actuate a lever 10 linked to a lever 16 which regulates the engine output or adjusts the ratio of a continuously variable transmission gear. If the lever 16 controls the transmission gear ratio, it may also, as at predetermined position during its travel, alter the engine speed from that associated with lowest specific fuel consumption to the maximum speed or to that providing greatest torque. In a tractor provided with a continuously variable hydrostatic transmission (Fig. 2, not shown) comprising a variable output pump (22) driven by the engine and connected by pipes (24, 25) to a hydrostatic motor, one of valves (28, 29) is opened when the adjustable portion (23) of the pump is positioned to provide maximum output, whereupon fluid from one of pipes (24, 25) is supplied to a cylinder (34) containing a piston (35) displaceable against spring loading to regulate the engine output. An exhaust pipe (38) restricted by a capillary bore enables fluid to be exhausted from the cylinder (34) when both valves (28, 29) are closed so that the piston (35) is restored to its initial position by the spring (36). In Fig. 3 the output of a hydrostatic transmission pump 22 is reduced should a traction wheel spin by a hydraulic ram 47 communicating through a valve 43 with a flow circuit 52 between a gear pump 53 coupled to a driven wheel and a gear pump 54 coupled to an undriven reference wheel. When the driven wheel slips the output of fluid from the gear pump 53 exceeds that returned by the gear pump 54 to a reservoir 56 and the excess fluid is supplied to the cylinder 47 to reduce the output of the transmission pump 22. Should the wheel continue to slip when the output from the pump 22 reaches a minimum, a projection 39 on the adjustable portion 23 of the pump depresses a spring-loaded contact plate 40 to displace the valve 43 and divert excess fluid from the gear pump 53 to a power device 50 which reduces the depth of furrow of a plough or adjusts the cutting angle of the ploughshare and/or mould board about a vertical or inclined axis.

Abstract: 1483187 Measuring flatness of anodes  electrically IMPERIAL CHEMICAL INDUSTRIES Ltd 30 Sept 1974 [22 Oct 1973] 49008/73 Heading G1N [ Also in Division C7 ] The flatness of an anode is assessed by bringing it into contact with a sheet of dielectric material on a rigid plane sheet of an electrically conductive material and measuring the capacitance of the capacitor so formed. The anode including working surface 5 to be tested, bridge piece 6 and hollow tube 7, is supported by a gyrofork 22 clamping the current lead-in rod 24 and connected to one end of a counterbalance arm 16 pivoted on a gyro-pivot 15. A weight 23 is movable along the arm 16 to counterbalance the weight of the current lead-in rod 24. The clamped anode is then lowered into contact with a dielectric sheet 4 on a cast iron member 1 and the height. of the pivot 15 adjusted by screw member 14 until the counterbalance arm 16 is horizontal. A capacitance bridge 8 and  indicator 9 is connected at 10 and 11 to the plate 1 and current lead-in 24 via the pivot and arm 15, 16 and the apparatus calibrated by measuring the capacitance using a range of anodes of varying flatness to obtain a reference value corresponding to the desired flatness. Meter 9 is then adjusted to give a zero reading after which the anodes to be tested are inserted in the apparatus. Positive readings on the meter, greater capacitance than the reference, indicate a satisfactory flatness whereas negative readings indicate an unsatisfactory anode.
