Title: False twist crimping
Inventor: SCRAGG FREDERICK
IPC: D02G1/02
Filed: 1964-10-30
Abstract: 1,129,472. False-twist crimping yarn. ERNEST SCRAGG & SONS Ltd. 18 Oct., 1965 [30 Oct., 1964], No. 44340/64. Headings D1F and D1W. A "false-twist" crimp rigidity (as determined by the test at 20 ‹C described in the Journal of the Textile Institute 1960, Transaction T435) of above 40% is imparted to 70 denier 34 filament nylon yarn by using suitable values ,of the yarn tension upstream and downstream of the false-twist device-for example between 5 and 9 gms. and 8 and 12 gms. respectively. The false-twist device and heater used may be those described in Specifications 1,085,052 and 1,089,793 respectively. The yarn may be posttreated to reduce the crimp elongation by heating the yarn on the run whilst in a partially relaxed state, or by steam treating a package of the yarn in a partially relaxed state.

Title: Modulator circuit
IPC: H03K7/00
Filed: 1962-11-23
Abstract: 950,176. Circuits employing magnetic storage cones; pulse modulation circuits. STANDARD TELEPHONES & CABLES Ltd. Nov. 23, 1962 [Nov. 27, 1961], No. 44410/62. Addition to 878,349. Headings H3B, H3P and H4L. In a blocking oscillator, a winding on a magnetic core having a rectangular hysteresis loop is connected in parallel with one of the windings of the feedback transformer, a signal source being inductively coupled to the core. Fig. 1 shows part of a blocking oscillator in which winding n a  of a transformer Tr is connected in the anode circuit of a valve (not shown) and regenerative feedback is provided by a winding n c  connected in the grid circuit. It is shown in the parent Specification 878,349 that the time integral of the output pulse is proportional to the flux variation in the saturable reactor C o  during the pulse. This principle is used in converting a pulse count modulation signal s (Fig. 2) into pulse duration modulation p. Core Co is first saturated by triggering the blocking oscillator by means of a pulse t on the grid. Each pulse s fed to terminals 1, 2 reduces the flux in core Co as shown in Fig. 2. At the end of each train s the circuit is reset by a triggering pulse t on the grid, the duration of the pulse generated in the output winding n o  being proportional to the change in flux in core Co and hence to the number of pulses s in the train. Demagnetization by the overswing n is prevented by diode d. If this diode is omitted, the circuit becomes sensitive to incremental (delta) modulation (Fig. 3, not shown). Pulse count modulators.-Fig. 4 shows part of another blocking oscillator comprising a further winding S 1  on a rectangular hysteresis core C 1 , capable of being saturated by a much smaller voltage-time integral than is Co. An analogue signal is sampled during time T 1  (Fig. 5), the sampled waveform being shown at s. This waveform is integrated by the previously saturated core Co. At the end of the sampling period T 1 , a number of trigger pulses t are fed to the grid, each pulse saturating the core C 1 , giving an output pulse p, the overshoot of which resets C 1 . Each pulse p increases the flux in core Co until saturation is reached, when winding So exhibits a low impedance and inhibits the generation of further pulses p. The number of pulses p in each train is thus proportional to the voltage-time integral of the sample s. Pulse signalling.-The sampled analogue signal s at a transmitting station may be converted into pulse count modulation by a circuit shown in Fig. 4 before being fed to terminals 1, 2 of a circuit shown in Fig. 1 at a receiving station where the signal is converted to pulse duration modulation.

Abstract: 1320552 Flattening and forwarding tubular film WINDMOLLER & HOLSCHER 25 Sept 1970 [27 Sept 1969 18 March 1970 17 July 1970] 45831/70 Heading B5B Tubular film 1 from a stationary flowhead is flattened and forwarded for treatment in another stationary location using apparatus comprising flattening plates 2, squeeze rolls 11, 12 and a laterally offset film deflecting roller or rod 13 arranged parallel to the squeeze rolls all of which are mounted on a plate 3 which oscilates through 360 degrees about the tubular film axis on a shaft 5. At least three further deflecting rollers or rods 14, 17 and 20, located in planes parallel to that containing the first deflecting roller, are provided further downstream and are alternately spaced near to and remote from shaft 5. These rollers are arranged for independent oscillation about the film axis' In use, each rod oscillates with an angle which decreases with increase in distance from the flattening plates, the film being finally taken off by stationary rolls 23, 24. Shaft 5 is oscillated by a motor and oscillation of the other rollers may be derived directly from the movement of the film. Such oscillation may be positively intercoupled, e.g. by gears 25, 26, 28 or by a lever mechanism, e.g. spherically movable lazy tongs (Figs. 5 and 6, not shown). Variations in the length of film, contained in the apparatus caused by the oscillation (due to rollers 14 and 17 being offset by distance A from the shaft 5) may be compensated for by arranging a cam 40 on shaft 5, which cam is followed by the end 18<SP>1</SP> of mounting 18 of roller 17, whereby the lateral position of this roller is cyclically varied. The rollers or rods may be stationary rods having an anti-friction coating on the rotatable rollers having optionally, rotatable outer coverings e.g. as disclosed in Specification 1,281,478. When shaft 5 is in the central position of its oscillatory movement, as in Fig. 2, the rollers 13, 14, 17 and 20 may all be parallel. Figs. 2-4 are views along shaft 5, Fig. 3 being at 90 degrees displacement and Fig. 4 at 180 degrees displacement, relative to Fig. 2. Rollers 14 and 20 may also be arranged so that their axis intersect the axis of oscillation (Figs. 8-12, not shown).

As shown, strip 2 has three frames 4a, 4b, 4c carrying data relating respectively to film frames 1, 2, 3. Initially the data is merely in the form of marked areas (e.g. 10a, 20a, and so on) which will not be read by a machine. When these areas are punched out, in various combinations as required, the holes can be read and interpreted by a machine. On the drawing, circles shown in full lines represent punched holes, and circles shown in broken lines are premarked but not punched. The zones Ia, Ib, Ic, each contain two marked circular areas. If the one adjacent the film edge is punched through, this indicates that the negative frame on strip 1 is considered printable. The other area (10a, 10b, 10c) is always punched, and is used to position the film. The groups of holes at IIa, IIb, IIc are punched in various combinations to indicate the number of prints required, and also whether any special (written) instructions are to be noted. The zones IIIa, IIIb, IIIc contain groups of holes which can be punched in various combinations to indicate exposure values, frame numbers, etc.

Abstract: 1282154 Containers; packages; caps for containers P A LATHAM and P E BREFKA 19 Sept 1969 46207/69 Headings B8C B8D and B8T [Also in Division B5] An axially collapsible container body 10 is formed by a spirally wound flexible strip having overlapping telescoping convolutions with the respective ends of the strip being fastened to the innermost and outermost convolutions. Axial extension of the body is limited by a tape 51, Fig. 8 (not shown), or by interlocking strip edge projections 21, 22, which may be integral with or separate additions to the strip or formed by overlapped plastics tapes 23, 24 secured to the strip when the latter is of cardboard, Figs. 7-7B (not shown). In a modification, Fig. 9 (not shown), a wire 52 connecting a lid 15 to a box 14 additionally limits the maximum extension of the container body. Alternatively, the strip inner and outer surfaces may be provided with interengaging ratchet toothed formations, Figs. 6 and 20 (not shown), so that the body may be collapsed but not extended. The lid 15 may be provided with an apertured dispensing spout 16 or may be flat with a peripheral edge 53 adapted to grip the outwardly rolled, flanged turned-back or beaded edge of the top convolution, Figs. 10-15 (not shown). The box 14 may be cup-shaped, Figs. 9 and 16 (not shown), or of inverted cupshape, Fig. 2, and may be circumferentiallystepped at 23, Fig. 3 (not shown), if the extreme end of the strip providing the inner convolution is not feathered, Figs. 18 and 19 (not shown). The container is formed by winding under a predetermined tension a strip cut from a roll 31 around a container base seated upon a mandrel 34, Fig. 4A. The formed container, in a collapsed coiled condition, is then placed on a shoulder 35 of tapered holder and expanded by a filling nozzle 38, which is progressively raised as the container is filled with ice-cream for example. A lid is finally applied to the filled container. The collapsible form of the container permits the level of the contents to be raised to the rim of the container as the contents are progressively removed, or to permit the formed containers to be stored in the collapsed condition. Alternatively fruit juice or other concentrates may be stored in the container in the collapsed condition; the container being extendable to a maximum volume sufficient to accommodate the required amount of water or other liquids such as milk for a pancake mix. The container may be of paper, cardboard, plastics sheet, plasticscoated paper, foil-coated paper or wax-coated paper. The spiral seam of the extended container may be lightly heat sealed to form a sealed mechanically weak seam, sealed with a tape, or the container enclosed in shrink-type sleeve. The strip may be plastics-coated inside and wax-coated outside, the extended container being heated to melt the wax to form a mechanically weak seal permitting collapsing of the container. Alternatively, the container may include an inner flexible bag.
