Title: Improvements in or relating to aircraft instruments
Inventor: KENDALL ERIC RAYMOND
IPC: G05D1/06
Filed: 1963-11-28
Abstract: 1,042,170. Aircraft instruments. SMITHS INDUSTRIES. Nov. 27, 1964 [Nov. 28, 1963], No. 47122/63. Heading B7W. [Also in Division G1] Prior Specification 1,032,466 describes a system for indicating at 22 (Fig. 1) the difference between the forward acceleration dV/dt of an aircraft, as measured by a pendulum-type accelerometer 10 giving (dV/dt+g sin #) from which a pitch attitude gyro 12 signal g#, which is approximately equal to g sin #, is subtracted, and the pitch rate of change d#/dt as measured by a pitch rate gyro 18, for use by a pilot during take-off. In the present Specification the indicator is fed with additional signals to ensure safety at take-off, or to provide signals during overshoot. For monitoring take-off conditions a potentiometer 32 is fed with a signal representing the predetermined pitch # L  for safe lift-off, which is compared with the # signal from gyro 12 and divided at potentiometer 28, by a factor T #  to provide signal (# L  - #)/T #  which is added via switches 27, 26 to the input to meter 22. The # signal may alternately be obtained from the pitch rate gyro 18 by integration. For monitoring overshoot conditions a potentiometer 33 is fed with a signal representing the predetermined change in pitch ##d for safe overshoot, which is compared with the change in pitch from the initial pitch # 1  when overshoot was selected, stored at 37, and the actual # signal, and divided at potentiometer 29 by a factor T#<SP>1</SP> to provide a signal [##d - (# - # 1 )]/T # <SP>1</SP> which is added via switches 27, 26 to the input to meter 22. Switch 27 may be manually set to add one of the additional signals, or neither, the overshoot mode being selected by a first operation which prepares the circuit, and a push-button switch which closes the circuit. When the signal at meter 22 is zero, switch 26 is automatically opened, and the circuit is then identical with that of Specification 1,032,466. A third signal representing the difference between the actual velocity and a required final velocity for the manoeuvre may also be fed to meter 22 (Fig. 2, not shown). The overshoot requirement may be initiated automatically if the engine throttles are fully open during landing.

Abstract: 1376518 Manufacture of fibre sheets KARLSTADS MEKANISKA WERKSTAD AB 13 Oct 1972 [15 Oct 1971] 47235/72 Heading D2A In the manufacture of fibre sheets, e.g. paper, using an initial fibre-stock suspension containing B.O.D., (biochemical oxygen dem- and) substances, the suspension is divided into flows 5, 6, the flow 5 is conveyed to a first sheet forming stage 7 in which a first layer 8 is formed, the flow 6 is subjected to a washing process 9 in which the original B.O.D. substances containing suspension water is replaced by water substantially free of these substances, the washed flow 11 is conveyed to a second sheet forming stage 13 and optionally to a third sheet forming stages 14 where layers are formed which are added to the layer 8, and the water removed in the first sheet forming stage 7 and the original B.O.D. substances containing suspension water from the washing process 9 is recirculated to the initial fibre-stock suspension. Wood associated with water is ground to a pulp at 1; the pulp being then screened at 3 with the recirculated water entering at 4. The water from the second and third forming stages 13, 14 and from a pressing stage 17 is recirculated to the washing process at 10. The three layered web 18 has the layer 8 as the centre layer and passes from the pressing stage 17 to a dryer (not shown). Clean water is supplied at 19 for cleaning, the press felts. Chemical wood-pulp may be added at 20. The layer 8 may be dewatered in forming stage 7 to a value such that its water content does not exceed the total water content of the three layered web 18, to prevent B.O.D. substances reaching the outer surfaces of the web during pressing. A web of more than three layers may be produced and this may be of cardboard or fibreboard. A paper-making machine for forming a three-layered web, Fig. 2 (not shown), has three successively disposed sheet forming double wire sections and a press section, the first forming section having a pervious forming suction roll, and the other two forming sections have impervious forming rolls which avoid dewatering through the first layer containing B.O.D. substances. The headboxes for the second and third forming sections are directed to one side of the previously formed layer or layers so as not to disturb these.

Abstract: 1453334 Feeding sheets RICOH CO Ltd 4 Nov 1974 [27 Dec 1973] 47556/74 Heading B8R A sheet conveying device, for example for feeding sheets between electrodes 5, 6 of a facsimile electrostatic image recording machine and thence to a developing device 17, comprises a first pair of feed rollers 7, 8, the roller 8 being driven by a stepping motor M 1  and a second pair of feed rollers 12, 13 downstream of the rollers 7, 8 by a distance less than the length of a sheet, the roller 13 being driven at a speed greater than that of the roller 8 by a friction drive, but being prevented from rotating when a lever 15 engages a tooth of a ratchet wheel 14, the lever relasing the roller for rotation when a solenoid 16 is energized. Two photo-electric detectors S1, S2 are provided, respectively upstream and downstream of the rollers 7, 8. In operation, with the rollers 7, 8 rotating and the rollers 12, 13 stationary, a sheet 1 is introduced past the detectors S1, S2 and between the rollers 7, 8, and is advanced by the rollers to the rollers 13, 14 where its leading edge is stopped. Operation of the detectors actuates a counter to count drive pulses fed to the motor M, and when a slight buckle 1A is formed, the solenoid 16 is momentarily energized to allow the rollers 12, 13 to grip the leading end portion of the sheet. The sheet is then advanced by the rollers 7, 8 to form a loop 1B. When the trailing end of the sheet passes the detector S1, the solenoid is again energized for a period determined by a timer and sufficient to feed the sheet to the device 17. The timer may alternatively be actuated when a microswitch detects the size of the loop 1B. The counter may be replaced by a timer which acts when the buckle 1A has been formed. The mechanism 14, 15, 16 may be replaced by an electromagnetic clutch.

Title: A device for locking and tensioning saw blades on their frames,and sawing machines provided with this device
Inventor: GUIOT HENRY
IPC: B27B3/30
Filed: 1962-12-20
Abstract: 967,129. Sawing. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 20, 1962 [Dec. 20, 1961], No. 48098/62. Heading B5L. [Also in Division E2] A device for locking and tensioning a saw blade 1 on the frame of a sawing machine of the reciprocating type comprises two tensioning systems, each co-operating with one of the ends of a saw blade and consisting of a base 2 adapted to be connected to the frame, support means 3 movable with respect to the base in order to hold the blade in one plane, pivoting means 5 for locking the blade on the support means, and a mechanical connection 8 between the support means and the locking means, one of the systems being a driving system and comprising means 11, 12, 14 for successively controlling the pivoting movements of the locking means and the displacements of the support means with respect to the base. The pivoting means on the driving system consists of an L-shaped lever 5 having two arms, one of which is connected by a pin 6 to a fork 7 and the other of which is connected by a pin 15 to a slide 11 which is movable relative to the base 2 and support 3 by a screw-and-nut mechanism 12, 14, the lever also being connected to the support 3 by a connecting-rod 8 and pins 9, 10. The support 3 has a projection 4 for engaging a hole in one end of the blade, the hole in the other end of the blade being engaged by a projection 4a on a slide 3a movable on a base 2a. A similar lever 5a and fork 7a is provided to retain the blade on the support 2a. To release the blade, the nut 12 is rotated to axially move the screw and slide 11 so that the lever 5 is pivoted to move the fork 7 from locking engagement with the blade 1 and projection 4, the slide moving until it abuts the support 3. Further rotation of the nut 12 moves the support 3 and the blade to cause the support 3a to slide relative to the base 2a and the lever 5a to pivot and remove the fork 7a from looking engagement with the blade and projection 4a. The blade can thus be removed and replaced, the new blade being tensioned by rotating the nut in the opposite direction. In an alternative embodiment, the nut 12 is replaced by bevel gearing and a sleeve nut. The device may be used in a machine which is in a place inaccessible to human operation, e.g. in a radio-active atmosphere, the nut or bevel gearing being operated by remote handling devices. If the saw blade breaks, the system 2a is operated by interposing a rod between parts on the supports 3, 3a so that movement of the support 3 causes movement of the support 3a.

Filed: 1963-12-10
Abstract: 1,040,263. Cathode-ray tubes. TOKYO SHIBAURA ELECTRIC CO. Ltd. Dec. 10, 1963 [Dec. 11,1962 (2); Dec. 29, 1962; Aug. 11, 1963 (3)], No. 48700/63. Heading H1D. In a flat cathode-ray tube, Fig. 3, the fluorescent screen 14 lies on a cylindrical surface of the envelope and the beam deflection centre 22 of the deflection system 17 lies in an extension of the cylindrical surface, the electron beam a being directed by the gun 16 perpendicular to the axis of the cylindrical surface and at an angle to the screen. A magnetic collimating lens 19 has zero field strength at the centre of the lens and increasing field strength, but with opposite sign, in opposite directions away from the lens centre. The lens may be electromagnetic or may consist, Fig. 6, of flexible triangular magnets 31-33 with or without core end plates, and with the triangular shape of the magnets possibly modified to have concave sides or to have asymmetrical configuration, Figs. 11, 12 and 13 (not shown), or with varied intensity of magnetization or varied composition of the magnetic material to compensate for large deflection angles and fringe effects. The apices of the triangular magnets need not abut and need not terminate in points. Deflection errors are eliminated by having non-uniform deflecting fields in the deflecting systems 17, 18, Fig. 3, which may be either magnetic or electrostatic. The fields may be curved or tapered and may be produced by asymmetrically disposed or shaped magnetic coils or polepieces or by electrostatic plates or in the case of coils, by having identical coils carrying currents of different magnitude. The deflecting systems 17, 18 may be superposed upon one another and with suitable fields the collimating lens may be dispensed with. The deflection errors may alternatively be corrected by providing a third fixed field deflecting system, the field being of a barrel-shaped configuration. The fluorescent screen 14, Fig. 3, may comprise a fluorescent film on a transparent conductive film 21 or the fluorescent film may be applied first and then coated with a thin metallic film. The screen may be constructed to be viewed on both sides or on one side only.

This arrangement enables vertical differences in expansion between the side walls and the supporting structure 4 to be taken up by elastic deformation by the unsupported outer edge region of the bottom tubes. As shown in Fig. 3 the bottom tubing is connected at 19 to the support grid in a manner which allows horizontal displacement by multiple ball-bearing 18. The outer ends of the beams are mounted at 5 to the supporting structure 4 via a member 7 which can pivot in a tube mounting 6 (to position 11) to accommodate outward expansion of the support structure (to position 10). The member 7 is also biased by a spring 8 to compensate for any slight differences occurring in the region of a particular side wall. As shown in Fig. 4 reinforcing beams 12 are also provided and these beams support the bottom tubes in the outer edge region at 16 to prevent their buckling. One end 13 of each beam 12 is suspended from the side tube wall and the other end 14 is displaceably mounted, by means of slot 15, on the support grid.
