Abstract: 1,149,830. Cleansing milking systems. WESTFALIA SEPARATOR A.G. 10 Nov., 1967 [28 Nov., 1966], No. 51222/67. Heading A1M. Apparatus for cleansing a milking system comprises a rinsing bath 1 containing cleansing solution, a suspension device 2 for carrying the teat cups 30 in the bath, control means operated from a vacuum source 33 for causing the teat cups to suck in cleansing liquid from the bath through their hoses 8 and the milk line 12, and means for causing the teat cups to be alternately immersed and clear of the cleansing liquid. One arrangement includes a storage vessel 4 into which cleansing liquid is drawn from the bath simultaneously with that by the teat cups so as to lower the level in the bath and expose the teat cups to suck air thereby destroying the vacuum in the storage chamber and allowing the liquid therein to return to the bath. Hose connections 8 are connected to an inner chamber (10) (Fig. 3, not shown) in a distribution housing 6 containing a pneumatically actuated valve which alternately connects and disconnects the inner chamber to and from the milk line. The cleansing liquid delivered to the milk -line is returned to the bath at periodic intervals through a trap device 32. In a modification the milking equipment is periodically lifted from the cleansing liquid bath. Foam rubber plugs may be introduced into the milk line at the end 35, to be pulled along by the cleansing fluid.

Abstract: 1300401 Conveying liquids by heating; reciprocating pumps UNITED KINGDOM ATOMIC ENERGY AUTHORITY 22 April 1970 [27 Jan 1969 21 Oct 1969] 4523/69 and 51464/69 Headings F1A and F1R A pumping arrangement comprises a chamber 11 having inlet and outlet connections 12, 13 and a means 15 for subjecting a fluid to be pumped in the chamber to repetitive pulses, there being a first fluid diode 17 in the outlet connection to permit easy outflow therethrough and a second fluid diode 18 in the inlet connection to permit easy inflow into the chamber but which restricts reverse flow therethrough. The fluid diodes may be of the scroll, vane or vortex type. The inlet connection may include a head tank (122) Fig. 3 (not shown), connected to the chamber' by a U-tube (112), and partially filled with liquid e.g. a noxious liquid, below a gas space (123 ), a tank inlet (124) includes the second fluid diode 18. The tank, U-tube and chamber 11 form an oscillatory liquid column whereby the means 15, consisting of a heating element embedded in a cover 14, vapourises liquid in contact with lower surface 16 so causing a pulse which pumps the liquid. The vapourised liquid condenses on expanding away from surface 16, and contacts surface 16 again to give a further pulse, a condenser may be provided to increase the pulse rate. The pulsing means may be electrolytic or mechanical e.g. a piston or it may include an air pulse acting through an intermediate fluid, compatible with the fluid to be pumped, (see Specification 831383). When an intermediate fluid is used this may be separated by a diaphragm from the fluid to be pumped. The pumping arrangement may be incorporated in a system employing four diodes in a manner analoguous to electrical diodes in a full wave A.C. rectifying system Fig.4 (not shown). Alternate positive and negative pulses e.g. air pressure are applied across one pair of terminals (315, 317) and inlet and outlet connections act as the other pair of opposed terminals (212, 213).

Abstract: 1,162,978. Quilted laminate. SMITH & NEPHEW PLASTICS Ltd. 15 Dec., 1966 [22 Dec., 1965], No. 54263/65. Heading B5N. A quilted fabric comprises two layers of airpervious material quilted one to each surface of an air pervious pad, at least one of the layers of air-pervious material quilted to the pad being a non-woven net of a thermoplastic material produced by stretching or stressing in two mutually perpendicular directions a thermoplastic sheet material having a regular pattern of embossments on, or cavities in, at least one surface. The pad may comprise a single layer of air-pervious material, a plurality of layers of such material, a random arrangement of chopped pieces, e.g. pieces of the non- woven net, held in position by the quilting lines, or compacted synthetic or natural fibres or threads. The thermoplastic sheet material may comprise an olefin polymer e.g. of ethylene or propylene, or olefin copolymer. When a non- woven net is only present on one side of the pad the other outer layer may be a fabric woven from natural or synthetic fibres. A finishing material, e.g. artificial or natural silk, or cotton, sheets may be glued or stitched to the surface of the quilted fabric. The layers of the quilted fabric may be united by heat sealing, e.g. by high-frequency welding, electrical impulse or resistance welding, or by heated patterned rollers; when the pad is thermoplastic, or by sewing when the pad is not thermoplastic. In one example the non-woven net is quilted by heat to one side of a pad of acrylic fibres and a fabric. of acrylic, e.g. Courtelle (Registered Trade Mark) fibres is quilted by heat to the other side. In another example (Fig. 1, not shown) non-woven nets produced by sequential biaxial stretching of an embossed sheet of highdensity polyethylene are heat sealed to each side of a foamed polyurethane pad. In a further example (Fig. 4, not shown), a non-woven net produced by simultaneous biaxial stressing of a high-density polyethylene sheet is heat sealed to one face, and a fabric woven from polyacrylonitrile fibres heat sealed to the other face of a pad of polyacrylonitrile fibres. The quilted fabrics may be used in garments, packaging, heat insulation, e.g. pipe lagging, electrical insulation, or table mats.

Abstract: 1405504 Automatic electric control of speed WERKZEUGMASCHINENFABRIK OERLIKONBUEHRLE AG 27 Nov 1972 [10 Dec 1971] 54685/72 Heading G3N A pulse multiplier 2 is provided between a controlling oscillator 1 and a digital summation (comparator) unit 3 of a control system for the motor driving the slide of a machine tool. The motor 8 drives an optical tachometer disc 9 to generate pulses in photo-cell 11 which are subtracted from the command pulses supplied to unit 3 from multiplier 2 to produce an error signal which gradually decays as the motor approaches the required position and the number of tachometer pulses equals the number of command pulses. When the error signal is zero the motor stops and the machine slide should be in the required position. The repetition rate of the tachometer pulses corresponds to the speed of the motor. The error signal is passed through a D/A converter 4 and PID amplifier 5 to a thyristor firing control 6 for motor 8.

Abstract: 1446850 Cartesion to polar co-ordinate converter PLESSEY CO Ltd 21 Nov 1973 [1 Dec 1972] 55540/72 Headings H3H and H4D A circuit for converting analogue cartesian co-ordinates X, Y to polar co-ordinates R, # (# digital) comprises a clocked counter providing a signal representing a progressively variable angle α, means receiving the angle signal and providing sine α and cosine α signals, multiplier means producing digital signals representing X cosine α and Y sin α, comparator means inhibiting further variation of the angle α when X cos α = Y sin α, the angle α then being #; means for producing complement signals X sin # and Y cos # and means for summing the complement signals giving R. Clock pulses are fed to 11 bit binary counter 16, the output of which represents the variable angle. The angle signal is fed to two true / complement devices which provide, under control of signals on lines 22, 23 either the angle or its complement to Read only memories 26, 27, which give as output the sine of the input angle. Initially the complement is supplied by 20 and the output of ROM26 is the cosine of the angle, while 21 supplies the true value and ROM27 the sine of the angle. The sine and eosin signals, together with the analogue co-ordinate values are supplied to respective multiplying D/A converters 30, 31 as shown and the output signals are passed to comparator 34. At equality of the X cosine and Y sine signals, the flow of clock pulses to counter 16 is stopped. The true and complement devices 20, 21 are then switched to their other states and the resulting X sine and Y cosine signals are summed at 36 to give R. The converter may be used in numerical control machines, gun turret control, video map generation and CRT deflection systems. It may also be used in a height finder radar system (Fig. 1) in which the X and Y co-ordinates of a target are generated from a plan position indicator display by potentiometers connected to a joystick or rolling ball marker. The bearing # is used to direct a nodding height finder radar aerial and the range information for distinguishing between several targets in line and to control the angle of nod which can be less for more distant targets.
