Abstract: 1,265,557. Toothed gearing. J. P. PALKHIWALA. 27 June, 1969, No. 32549/69. Heading F2Q. A reduction gear between coaxial shafts 1, 27 comprises an internally toothed gear meshing an externally toothed gear, one of the gears being coaxially secured to the low speed shaft 27, and the other gear being rotatably mounted on a crank-pin 4 of the high speed shaft 1 for gyratory motion, rotation of said other gear about its own axis being prevented by interconnection to the gear casing 3 by an Oldham type coupling having ball or roller bearings between its coupling surfaces. As shown, the gyratory gear 5 is externally toothed and the output gear 7 is internally toothed. In Fig. 3 (not shown) the gyratory gear (31) is internally toothed and the output gear (32) externally toothed. In Fig. 1, diametral grooves 9, 12 in adjacent faces of a flange 8 on the gear 5 and an intermediate member 11 are drivingly connected by balls 14 in a flat cage 16. Similarly, balls 23 in a cage 25 connect slots 20, 21 in adjacent faces of the intermediate member 11 and the casing 3, the slots 20, 21 being at right angles to the slots 9, 12. The crank-pin 4 carries a balance weight 26. Nuts 30, 55 on the shaft 1 allow for taking up slack, e.g. due to wear. In a modification (Fig. 4, not shown) the gyratory gear (41) and the casing (3) have diametral ribs (40, 34) which engage in rectangular section diametral slots (39, 35) in the intermediate member (36) via rollers (37) held in cages (38) of U-shaped crosssection, the slots (39, 35) being at right angles to one another.

Abstract: 1,265,988. Knitting-machines. WILLIAM COTTON Ltd. 22 Oct., 1970 [28 Oct., 1969], No. 52647/69. Heading D1C. A straight bar machine is provided with latch needles 6 lockable to needle bar 7 for knitting by a bar 10 engaging an upper butt 6c. The needles can be disengaged by lowering the bar to act on butts 6d. To effect fashioning or lacing the bar 10 is raised to below the upper butts of the lowered needles shown and the appropriate needles then raised by eyeletted transfer points 16 to clear the loops below the latches. The bar 10 and points are then lowered to draw the needles through the loops which pass onto the points. The points are then shifted laterally and transfer their loops. The upper part 10b of the bar may comprise a series of cut-outs and projections, and can be shogged so that the latter engage each, or alternate butts for plain, or rib knitting respectively. A latch opener is provided.

Abstract: 1,266,099. Automatic control of temperature. HONEYWELL Inc. July 7, 1970 [July 7, 1969], No.32841/70. Heading G3R. In a rotary kiln for cement manufacture, and heated by air forced by a fan 7 across a burner 5, the fuel supply to the burner is automatically controlled to maintain desired temperature levels in the kiln, by a master controller 16 operating on a fuel valve 14 in dependence upon the difference between current input in lines 17, 18 respectively. Input through 17 is proportional to fuel-flow rate detected by a differential pressure sensor 19 and converted to a current signal by a transducer 20. Input through 18 is from a comparator 30 and represents the difference between the temperature at the burning zone as sensed by a radiation pyrometer 32 and a reference value derived from a D. C. output signal from a master set point transmitter 21 across R25 and applied via switches 27, 28 when closed as shown. With the switches 27, 28 open, the set value is modified by signals significant of the temperatures in a stationary pre-heating zone 10 and a rotatory heating zone 11 respectively. The temperature of zone 10 for example is sensed by a thermocouple 35, converted to a current signal by a unit 36 which passes current through an ammeter 37 calibrated to read temp. and through a potentiometer 38. The potentiometer 38 is electrically and mechanically coupled by its slider to a potentiometer 43 which receives constant current from a set-point temp., indicator 41. A voltage representing a temperature deviation from the setpoint at 41 appears across switch 27. The zone 11 temp. is likewise monitored, its thermocouple 35' being connected by slip rings 52 to the comparison circuits. Instead of applying a set temperature signal from unit 21, there may be applied across R25 a signal from a transmitter 57 depending upon the temp. of a calcining zone 12 sensed by a thermocouple 54.

Abstract: 1296045 Digital data storage FUJITSU Ltd 4 Dec 1969 [4 Dec 1968] 59373/69 Heading G4C Input data represented by the presence or absence of a data pulse in the interval between clock pulses is separated from the clock pulses by a circuit which generates a gating pulse from a data pulse if it exists or from a clock pulse if the data pulse is absent in the preceding interval. If a data pulse is present, it passes through gate 18 to set a bi-stable 12 and the delayed (10) data pulse is able to pass through a gate 11 to set a monostable trigger 15. The half bit period output from 15 is delayed by “ bit period at 16 so that gate 18 is again enabled ¥ to 1“bit periods after the data pulse. Bi-stable 12 is reset after ¢-bit period by the clock pulse which ends the period containing a data pulse by way of gate 17. If the next bit period does not contain a data pulse, gate 13 is open when the clock pulse arrives at the end of the period and monostable 15 is again triggered, the gating signal applied to gate 18 being on from “ to ¥ of a bit period following the clock pulse.

Abstract: 1307849 Extruding foamed thermoplastic sheets MONSANTO CHEMICALS Ltd 14 Sept 1970 [6 Oct 1969 11 Dec 1969] 48918/69 and 60577/69 Heading B5A [Also in Division C3] A foamed thermoplastic resin sheet is produced by extruding a foamable aliphatic, or polyamide, or polyester thermoplastic resin through a slit die orifice 3, to expand in a zone 5 of lower pressure defined by opposing concave circular or parabolic surfaces 6, 7, cooled at a temperature below that of the extruding resin. In the Fig. 4 embodiment, the die is constricted by a strip 4 and the surfaces 6, 7 are formed on adjustably spaced apart chromium plated steel plates 8, 9, which are spaced at 11, 10 from the die to reduce heat conduction, and are provided with water cooling channels 12 to reduce the temperature of the surfaces 6, 7 to from 10‹ to 85‹ C., and preferably 20‹ to 70‹ C., below that of the extruding resin. Flat surfaces are provided on water cooled plates 13, 14 of adjustable inclination, and roller pairs 16, 17, which are spaced apart by the thickness of the sheet, may be provided to assist in ensuring that the foaming resin completely fills the zone 5. The flat surfaces may also be parallel, or slightly convergent, and, from the point of maximum expansion, freely rotatable or driven opposed belts may be provided instead of the rollers. In the Fig. 6 and 7 embodiment, the zone is defined by concave surfaces integral with the die, and the sides of the zone are also defined by concave surfaces 109, 110; flat diverging surfaces or rollers may also be provided as in the Fig. 4 embodiment. The convex surfaces may alternatively be cooled by oil, or by air, the rear of the surfaces may be provided with fins to enhance cooling, and the surfaces may be insulated from the die by thermal insulating material. The Specification refers to various thermoplastic resins, blowing agents, extrusion temperatures and pressures and die dimensions, and dimensions and densities of the extruded sheet, and various examples are given of the extrusion of polyethylene and polypropylene. The sheet produced has a surface skin oriented in the direction of extrusion and of higher density than the inner foamed mass, which comprises elongated cells oriented substantially at right angles to the skin and the majority of the cells having a ratio of length to width of 1À1 to 2À0 to 1, e.g. of 1À5 to 1. The cells may be substantially circular in their width cross-section, but may also -be elliptical or hexagonal, the width being from 0À001 to 0À05 inch.
