Title: Suction pick-up roll assembly for paper making machines
Inventor: STEWART ALEXANDER ERIC
IPC: D21F3/10
Filed: 1954-12-09
Abstract: 775,206. Suction pick-up rolls of paper-making machines &c. DOMINION ENGINEERING WORKS, Ltd. Dec. 9, 1954, No. 35731/54. Class 96. A suction pick-up roll 5, Fig. 2, of a fourdrinier paper-making machine &c. is mounted for swinging movement about a pivotal axis A in a bearing bracket 160 for the main suction conduit 167, the corresponding pivotal bearing for the other end of the support for the roll 5 being at the axis of a drive shaft 20, Fig. 5, carrying a sprocket (not shown) for a chain drive for the roll 5. The web is picked off the wire-cloth 151a at a position adjacent the couch roll 152 and transferred to a pick-up felt 151 with the aid of a high-vacuum zone 46, Fig. 24, which adjoins a zone 47 of lower vacuum which counteracts the effect of centrifugal force tending to throw the web from the felt. The sealing-strips for both zones are pressed against the inside of the roll shell with the aid of pneumatic tubes 68 pressing against non-corrosive strips 72. Each zone is divided by a transverse partition into a short length near the end 9 of the roll for the lead-strip which is cut on the wire-cloth on starting-up, and a much longer length for the remainder of the web during normal running. Suction is applied to the suction box through valves &c. which can be actuated by turning hand-levers 122a and 149a. For normal running both sections of the high vacuum zone 46, and both sections of the low, 47, are respectively at the same degree of suction, and the two valves which are frictionally engaged normally rotate as a unit when the valve-control lever 122a is turned. The longer compartments of both suction zones 46, 47 are interconnected through a port &c. with a vacuum-reducing metering plug, and are opened to the atmosphere for starting up. The position of the suction zones can be adjusted with the aid of a spanner &c. applied to an end 34 of a worm-shaft 32 to turn a worm-wheel 30 which is keyed to the suction box journal 22.

Title: Amplification of electrical signals in imaging systems
IPC: H04N5/30
Filed: 1974-08-14
Abstract: 1511492 Television HAWKER SIDDELEY DYNAMICS Ltd 12 Aug 1975 [14 Aug 1974] 35759/74 Heading H4F D.C. restoration in an imaging system is effected by a sample and hold feed back network. A detector 1 scans a field of view in a raster pattern. A current bias is applied across the detector. A D.C. preamplifier 2 amplifies the signal from the detector 1. Before each active scan line a reference source of radiation is imaged on to the detector and a sample/hold switch 5 is closed. A D.C. amplifier 4 is then fed with the preamplifier output, phase inverted by a phase inverter 3. This charges the feedback capacitor 7 of the amplifier 4, until the output of the preamplifier is driven to equal a reference voltage 6, shown in the drawing as 0 V. Before the beginning of the next active scan line switch 5 is opened and the preamplifier mean output level is maintained at the reference voltage 6 throughout the next scan line by the charge stored on the feedback capacitor 7. The component values can be chosen such that this capacitor is small, typically 0À01 microfarads.

Title: Improvements in and relating to the manufacture of corrugated metal tubes or bellows
IPC: B21D15/10
Filed: 1963-09-12
Abstract: 1,103,113. Corrugating tubes. J. H. MILLAR. 8 Sept., 1964 [12 Sept., 1963], No. 36032/63. Headings B3A, B3E and B3Q. A method of corrugating a metal tube 4 comprises surrounding the tube with two dies 6, 8 having an internal recess 16, 20 of the same width, when closed, as the desired corrugation, expanding the tube in the die-recess by internal pressure to form a corrugation, releasing the internal pressure somewhat, withdrawing the die 8 longitudinally and then forcibly re-closing or " kicking " the die 8 against die 6 to set the corrugation to its final form. The internal pressure may be applied hydraulically or, as shown, by a plug 36 of rubber compressed against the end of a mandrel 2 by a member 38 drawn endwise by a rod 42 passing through the mandrel. In a preliminary operation, Fig. 2, die 8 is adjusted endwise by an hydraulic motor 22 above or below the dies and a lever 26 to space the co-operating parts 16, 20 of the recess formed in the end of die 8 and in an internal shoulder in die 6. In this position the rod 42 is operated by an hydraulic motor 40 to expand the tube. The die 8 is then moved endwise into engagement with the shoulder in die 12 and the plug further compressed to form the corrugation. Reduction of the compressive force on the plug 36 follows and withdrawal of the die 8, allowing the corrugation to spring back. The die 8 is then struck back against the shoulder in die 12 to set the corrugation. Stops (not shown) for the rod 42 correspond to full and partial compression of plug 36. Sectional dies; feeds.-Die 12 is in two sections which may be separated by a motor operating a toggle linkage or, as shown, by a pair of hydraulic motors 18. The dies are then moved along the tube by an hydraulic motor 32 and a toggle mechanism (not shown) before being re-engaged with the tube, the last corrugation entering a recess 14 in die 12. Return movement of the dies by motor 32 feeds the tube along the mandrel 2 by an amount equal to the pitch of the corrugations.

Abstract: 952,884. Electric motors. SUNBEAM CORPORATION. Oct. 27, 1960 [Jan. 18, 1960], No. 36985/60. Heading H2A. The voltage induced in an open-circuited stator coil of an impulse motor for multi-voltage working is restricted by the presence of a closed loop of electrically conductive material around the magnetizable stator core of the motor. The embodiment described has serially connected field coils 17a, 17b, 17c, 17d whose junctions are connected to selector switch 45 allowing multi-voltage working. .Coils 17a, 17b, 17c are wound in order on a split plastic, e.g. nylon bobbin 57 on the magnetizable core and a short-circuited strip 71 of copper foil is then placed around them and overwound by high voltage coil 17d. The thickness of the copper strip is chosen so that while adequate reduction of the voltage induced in coil 17d when open-circuited is obtained the heat dissipation in the copper strip is not excessive. Contact breaker 31, operated by a double eccentric cam 29 on the armature shaft and having parallel capacitor 51 and resistor 53 to reduce arcing, is connected between coils 17a and 17b so that these coils provide additional interference choking to that provided by R.F. chokes 55.

Title: The production of yarns
Inventor: GUTHRIE JOHN CHARLES
IPC: D02G1/18
Filed: 1961-10-17
Abstract: Yarn is formed by stretching regenerated protein e.g. freshly spun casein, continuous filaments by 20-60% while wet, drying while still stretched and combining e.g. uniformly or randomly mixing, the dried filaments or staple thereof with less shrinkable continuous filaments or staple fibres, spinning and, optionally, doubling.  The less shrinkable fibres may be of regenerated cellulose, cellulose acetate, polyethylene terephthalate, polyamide, polyacrylonitrile, cotton, flax or wool or another regenerated protein.  The potential shrinkages of the constituent fibres differ by at least 5% and the proportion of more shrinkable fibre is 20-50%.  The yarn or fabric made therefrom is bulked by immersion in an aqueous fluid e.g. hot or boiling water or steam, which may occur in a normal e.g. dyeing or finishing, treatment, to cause differential shrinkage of the fibres, followed by drying under minimum tension.  The stretched fibre may be only partially dried or temporarily set e.g. by a cross-linking operation the effect of which is removed by aqueous treatment, to retain its full shrinkage potential pending a delayed bulking treatment.

Filed: 1974-08-23
Abstract: 1482955 Measuring temperature of axle bearings G PUSCH 23 Aug 1974 [31 Aug 1973] 37187/74 Heading G1A The temperature of the axle bearings of rail vehicles is measured by sensing infrared radiation emitted from the bearing alternately with radiation emitted from a reference source. In the arrangement of Fig. 2, radiation from the underside of an:axle passes through the open top of housing 18 to a mirror 6, rotated by motor 16 to throw off dirt, &c., radiation reflected therefrom reaching detector 21 via lens 1, a modulator 3 in the form of a shutter disc and an apertured diaphragm 2. The detector, which may be a cadmium-mercury-tellurium device having a peak at 3-5Ám, may have Peltier cooling at 14, as may modulator 3, at 13. The detector output is passed via amplifier 31, band pass filter 32 and main A.C. amplifier 41 to a rectifier 37, whose peak output is coupled via low-pass filter 42 to linearizer 44 connected to an indicator 47 and to a threshold switch 36, which digitizes the input for transmission to a central station, where printer recording of signals for all axles is carried out, and hot axles are indicated by an acoustic or optical alarm. The digitizer signal is compensated for ambient temperature changes sensed at 46. In the arrangement of Fig. 2, the reference temperature is represented by that of the blades of the modulator, and this may also be the case in the apparatus of Fig. 3, (not shown) where the prongs of a tuning fork which operates as the modulator, are effective as a reference source. (In this apparatus, louvre blades are provided to prevent material thrown from mirror 6 reaching the detector). Alternatively, if the modulator blades or prongs are reflective, they reflect the cooled detector image back on itself and it acts as its own reference source. When the cover 28 is down, a standard radiator 27 is effective to provide a signal level during standby. Alternatively, the modulator is in operation to provide this level. Standby condition occurs when magnetic switches adjacent the track and spaced apart either side of the detector unit, Fig. 5 (not shown) sense the approach of a train. This causes cover 28 to open, motor 16 to start and axle counting to commence. A local magnetic switch adjacent the detector unit triggers an actual measurement operation for each axle.
