Title: Spinning device
IPC: D01H4/10
Filed: 1968-09-18
Abstract: 1,246,115. Open end spinning. MASCHINENFABRIK RIETER A.G. 18 Sept., 1968 [27 Sept., 1967], No. 44264/68. Heading D1D. An open end spinning rotor open on the side through which the fibre feed enters has means for evacuating air therefrom arranged on the rotor and spaced from the fibre collecting surface and from the path of fibre feed from feed inlet to the collecting surface. As shown the rotor has an upwardly extending flange 23 into which a correspondingly shaped projection on the cover fits with a small clearance. The projection is formed with a helical slot 22 which so combines with the adjacent flange on the rotor as to evacuate the rotor. Flange 23 and the projection are cone-shaped so that vertical adjustment of the projection by a screw ring 25 adjusts the separation of flange and projection. In Fig. 6 not shown a fin is provided on the projection. In Fig. 9 not shown the outside surface of an upwardly cone shaped rotor flange is closely approached by a correspondingly shaped cover in the surface of which there is a helical groove. In other forms the outside surface of the rotor is provided with radial blades or as in Fig. 7, not shown, a ring (28) which act to expel air from the chamber surrounding the rotor thus evacuating the chamber.

Abstract: 1405009 Digital clocks OMRON TATEISI ELECTRONICS CO 26 Sept 1972 [4 Oct 1971] 44412/72 Heading G3T [Also in Division G4] An electronic calculating apparatus includes a digital clock section, a calculator section, a keyboard, and a common display, the keyboard including a manually operated key arranged selectively to connect either of the calculator and clock sections to the display thereby selectively to display the result of a calculation and the time, Register 3 is a 24 bit shift register whose  contents recirculate via gate G4. The register stores a time value in hours, minutes and seconds in four bit BCD digits, shifting being controlled by six decimal digit shift pulses each subdivided by four bit shift pulses. Pulse generator 1 produces one pulse per second which is added to the time data in full adder 2. A carry circuit 4, Fig. 4 (not shown), consists of gating circuits connected to the four left most bit storage cells in register 3. The gating circuits, which are enabled by appropriate decimal digit and bit shift pulses determine when carries between the second and minutes and between the minutes and hours (to a radix of six) are required by supplying a full adder within the register with the appropriate filler digits. A gating circuit is also provided to determine when the hours data reaches 24 and to supply the appropriate filler digits to cause the hours to be reset to zero.  By actuating a key 5, which may lock in the position to which it is set, or which may be of the self return type, one of gates G2 and G5 is enabled to cause either the time data or the result of a calculation in the calculator section (which is said to be a conventional four rules arithmetic device) to be transferred to display register 6 and displayed. The display may be number tubes, photoemissive diodes or a printer. To reset the time in register 3 a clear key 11 is actuated which blocks recirculating gate G4. A new time, fed into shift register 10 from the keyboard, is then inserted via gate G7. In a second embodiment, Fig. 5 (not shown), register 10 is omitted time data being inserted directly into display register 6. Clear key 11 is then actuated, gate G4 is blocked, and an additional gate (G8) enabled to recirculate the time data from register 6 into register 3. The device may be used to determine the time taken to perform a calculation.

As shown, the differential amplifier output is compared, 62, with a reference to control the heating current to the thermistor 16 to counteract change in the output. The control input 113 is itself derived from an oscillator 41, an underground thermistor 36 and a rectifier 46 buffered, 54, to the input 113 so that equalizer loss is a linear function of the ambient temperature and the inverse of the control voltage at 113. Potentiometer 44 adjusts the equalizer characteristic slope, thereby altering the line length compensation, whilst potentiometer 54 sets the initial value of loss.

The water on entering through an inlet conduit 28 strikes a plate 30 and the resulting droplets 58 are uniformly distributed. The oil enters through two conduits 36 and 50 each provided with a flow control valve 54 and 56. The downward flow rate of the water droplets and the volume ratio of water to oil in the column can be regulated by adjusting the flows of oil entering the column through the inlets 36 and 50.

A system employing a pair of liquid-liquid heat exchangers 70, 72 and utilizing a third intermediary liquid to transfer heat between two liquids without the two liquids coming into contact with each other is shown in Fig. 6. The system is used in recovering heat from fresh water produced in a multistage flash evaporation type desalination plant and transferring this heat to the incoming sea water. Oil is used as the intermediary liquid. Each column has a number of flow control assemblies each comprising a hollow tubular member 112 whose upper end is closable by a butterfly valve 118 the position of which is adjustable. A pair of cross-over conduits 128 and 130 each having an associated regulating valve 132 and 134 are provided to transfer oil from one column to the other at various points.
