Abstract: 1,230,827. Cutting extruded material. SCHIESSER A.G. RUBBER & RAILROAD RESEARCH. 19 Aug., 1968 [24 Aug., 1967], No. 39621/68. Headings B4B and B5A. Automatic apparatus for accurately cutting sections from a length of solid or tubular extruded material comprises a roller conveyer 21, Fig. 2, along which the length of material to be cut is passed, an electric motor 11, Fig. 1, an intermittently operable counterweighted cutting knife 18 mounted on a shaft 15 connectable via a rapidly-acting clutch 13 to the shaft of the motor 11, and a brake 16 for the shaft 15 which operates alternately with the clutch 13. Material to be cut is fed along the conveyer 21, past the then stationary knife 18 until its leading end interrupts the flow of light from a source 26 to a photo-cell 25. The photo-cell thus emits a control pulse to an electronic device which causes the brake 16 to be released, the clutch 13 to be engaged, and hence the knife 18 to be rotated and the material cut. After cutting the blade 18 operates a sensor 28, which sends a further control pulse to the electronic device which causes the clutch 13 to be disengaged, the brake 16 to be applied and hence the knife 18 to be stopped in its original position. The cut lengths are advanced by a roller conveyer 24 travelling faster than the conveyer 21. The motor 11, clutch 13, brake 16 and knife 18 are mounted on a tiltable support 6 so that the angle at which the material is cut may be varied.

Abstract: 1,239,025. Digital transmission systems. INTERNATIONAL STANDARD ELECTRIC CORP. 1 Aug., 1968 [9 Aug., 1967], No. 36739/68. Heading H4P. A frequency shift receiver determines the frequency of the waveform being received by inspection of the time of occurrence of the zero transitions in the waveform, the resultant binary signal being fed to a majority decision circuit which regenerates the signal. The received signal at 2 passes to a Schmitt trigger 4, the resulting square wave frequency shift signal a passing to gate 26. Each positivegoing transition triggers bi-stable 25. It also triggers bi-stable 6 which enables gate 8 which passes clock pulses to divider 20, the latter giving a pulse h which occurs at the first negative-going transition of an imaginary signal having a frequency midway between the shift frequencies and having a + going transition coincident with the + going transition in a. Pulse h is delayed at 28 to give a pulse I which is gated with a at 26. If the lower shift frequency is being received a will still be high when l occurs, resulting in a pulse m which sets bi-stable 30 to the O-state. The output of bi-stable 25, which is reset by h, is i and this is gated with a pulse g which occurs at a set time, determined by delay 23, after the - going transition in a. If the higher shift frequency is being received, i will be high when g occurs, resulting in a pulse j which sets bi-stable 30 to its 1-state. The bistable 30 output n, n represents the demodulated data and passes to 7-bit shift-register 36 forming part of a majority decision circuit. The register is stepped by the shift frequency pulses m and j, i.e. the register contains 7 samples of n, n, the sampling rate being at the appropriate shift frequency. The 7-bit parallel outputs are summed at 39, 40, resulting in shift frequency rate multilevel signals indicative of the disparity of the samples in the register. When the disparity exceeds, e.g., 4, the corresponding unit 41, 42 sets bi-stable 43 accordingly, the 1 and 0 outputs of the bi-stable feeding a teleprinter. Reference has been directed by the Comptroller to Specification 960,976.

A travelling strand which may be a yarn, tape or film is false twisted by being passed about a freely rotatable roller 10, 58, the beginning and end portions of the loop combining to form a simple knot on the roller periphery and the strand leaving the roller in a non-tangential direction. The degree of false twist inserted can be increased by increasing the diameter of the roller 10 by decreasing the angle between the approaching and departing strand (for which purpose movable guide rollers or bars may be provided) and by increasing the tension in the approaching strand. In Fig. 6 the roller is provided (e.g. in air bearings) in a false twist tube which is rotated the two false twists being inserted reinforcing each other. The false twist method may be used in the processing of wet-spun linen, Fig. 2, not shown, in an open end spinning process, Fig. 8, not shown, in the fibrillating of film or the separation of interconnected filaments. It may also be used in the bulking of filaments either by being placed downstream of a heater or as shown in Fig. 5 by being placed upstream of a heater 50 to insert a false twist prior to the insertion of the main false twist by a twist tube 52 downstream of the heater. A twist tube of the type shown in Fig. 6 may be substituted for the tube 52.

Abstract: 1290538 Shutter control means EASTMAN KODAK Co 2 Oct 1969 [4 Oct 1968] 48556/69 Heading G2A A shutter 2 can move from a first position in which the lens aperture 1 is covered (Fig.1) to a second position in which it is uncovered Fig.2 (not shown), the said movement being retarded by means which varies as a function of the scene illumination intensity. As shown, the shutter is a plate 2 whose movement is guided and limited by a pin and slot arrangement 7,8. On release from the cocked position of Fig.1, the shutter is drawn to the right by a spring 3, the exposure being effected when an opening 6 passes across the lens 1. The shutter has a serrated edge 9, and as it moves, teeth 24,25 of a centrally pivoted member 20 engage alternately in the serrations escapement-fashion, so retarding the movement of the shutter. Below member 20 is an E-shaped electromagnet 10, whose central leg 11 is surrounded by a coil 12. The coil is in circuit with a current source 13 and a variable resistor 14, a photo-resistive element 15 being connected in parallel with the coil 12. Thus the higher the light intensity falling on element 15, the lower the current passing through the coil, and conversely. The strength of the electromagnet is highest at the lowest light levels. Thus the lower the light level, the greater the attraction between the magnet legs 16,17 and the arms 22,23 of member 20, so the retardation effect is increased, giving a longer exposure time, The shutter speed can be calibrated by variable resistor 14. Fig.3 (not shown) is a modification in which member 20 has a tooth at one end only.

Abstract: 1290678 Electric traction motor ELECTRICITY COUNCIL 26 Oct 1970 [4 Aug 1969] 38927/69 Heading B7H An electric traction motor 10 of a vehicle is coupled to an impeller of a torque inverter 21 which via a fluid drives a turbine on an output drive shaft connected to the driving wheels 22. A stator is mounted on a free wheel between the impeller and turbine. When a speed differential exists between the impeller and turbine, the stator is locked on its free wheel to provide torque multiplication. The torque ratio drops as the turbine speed increases and reaches 1 : 1 when the turbine speed is approximately 90% of the impeller speed at which point the stator will free wheel. Preferably two field windings 11, 12 can be switched alternately into series (for full field, low speed operation) or parallel (for weak field, increased speed) with the motor 10. In addition the battery may be divided into two equal parts which can be connected in series or parallel by contactors (not shown). A control 20 has a foot control movable through three intermediate positions to a final position so that a smooth sequence of operation in order of increasing speed is achieved. In the first position the battery halves are in parallel connection and the field windings 11, 12 are switched from series to parallel connection, the battery halves are then switched to series and the windings again switched again from series to parallel connection corresponding to the fully depressed condition of the foot control.

Abstract: 1296894 Measuring fluid-flow electrically YOKOGAWA DENKI SEISAKUSHO K-K 24 June 1970 30711/70 Heading G1N [Also in Division G4] A flowmeter measures the flow velocity in a pipe by means of a rod shaped object which generates a street of Karman Vortices, which are counted, in order to determine the flow velocity. A rod shaped object 2, is provided in a pipe 1 1 , and has a transverse bore 21 passing through it. The fluid passing by the object generates a street of a Karman Vortices and the generation of these Vortices creates alterative pressure differentials on each side of the transverse bore 21. These pressure fluctuations may be detected by a sensor e.g. a hot wire anemometer inside the bore, and the number of fluctuations may be counted to determine the number of Karman Vortices generated. The flow velocity may then be determined from the formula f = K.V/D. Where f = no. of Vortices; V-flow velocity; D = diameter of rod; and K is a constant. The bore passing through the rod shaped object may have a number of geometrical forms. It may comprise a cylindrical passage 21 with a larger diameter cylindrical passage 23 at the centre of the rod. It may also comprise ports 21 leading into hollow chambers 23 separated by a wall 24 and having a detection element in a hole passing through the wall 24. Many variations on the geometry of the bore and the arrangement of the detecting element are possible. Two rod shaped objects may be arranged in the pipe so that one rod shaped object detects the Karman Vortices generated by the other; both rod shaped objects may have transverse bores containing detectors so that flows in both directions may be detected. The flow fluctuations may be detected by means of a bridge circuit whose output is fed to an amplifier, and then fed to a counter. A feedback resistance between the output of the amplifier and the detector may be provided so that in the case of a hot wire anemometer the temperature of the wire is maintained constant. Reference is made to Specification 1296895.
