Title: Improvements in or relating to the control of wing flaps on aircraft
IPC: B64C13/00
Filed: 1935-12-05
Abstract: 466,800. Controlling aircraft. HAMILTON MOTORS (LONDON), Ltd., and THEED, W. D. L. Dec. 5, 1935, No. 33735. [Class 4] Aircraft wing flaps are actuated by power derived from the suction of the engine or power unit, the power supply being controlled by a manually-operated device such that the flaps can be set and maintained in any desired position between the fully raised and fully lowered positions. In one form, Fig. 1, a wing flap A is connected to a torque tube B fitted with a crank B<1> connected to rod C<2> of a double-acting piston C<1> working in a servo cylinder C. Opposite ends of cylinder C communicate through flexible pipes F, F<1> with casing G<1> of a four-way rotary valve G. The valve casing has a port G<5> communicating with a suction reservoir E and a port G4 open to atmosphere. Valve G can be set to place either end of cylinder C in communication with reservoir E at the same time opening the other end to atmosphere. By turning to valve to close all the ports the piston C may be maintained in any adjusted position. Piston C<1> is urged into the flap " up " position by a spring B<2> connected between a fixed part of the wing and an arm B<3> on lever B<1>. Tank E communicates with the engine induction pipe or supercharger air intake by a non-return valve E <2>. In a further modification, Fig. 2, a follow-up device is incorporated. A hand lever J controls the position of a piston valve H<2> working in a cylinder H axially movable under control of a link L attached to lever B<1>. In this case a single acting piston is used spring- urged to flap " up " position. Means may be provided whereby movement of the valve control lever beyond the range necessary for controlling the servo-motor may cause direct adjustment of the flap.

IPC: G01N21/05
Filed: 1965-08-06
Abstract: 1, 112, 602. Photo-electric absorptiometers. CESKOSLOVENSKA AKADEMIE VED. Aug. 6, 1965 [Aug. 11, 1964], No. 33793/65. Heading G1A. In an apparatus for taking and recording (photo-metric) measurements of a liquid stream by intermittently injecting samples of the liquid into a flow-cell, the latter includes two inlet ports, one for the liquid and one for a gas, an an outlet port through which the sample of liquid and gas is exhausted after each measurement. The gas, which may be air, ensures that a correct size sample is taken and also that the samples are completely removed from the cell after each measurement. The apparatus is used in a column chromatography device where it is required to continuously measure the absorption of a coloured liquid. A pen recorder of the point type is used for recording the measurement derived by a photo-electric cell which receives light after passage through the liquid sample. The recorder switches off after each measurement and at the same time causes the existing sample to be expelled and a new sample to be inserted into the flow-cell. In Fig. 1a, the flowcell comprises a quartz or glass tube 1 having at one end a shaped bung 3 through which hollow needles 4 and 5 for the liquid and gas respectively project and at the other end a bung 2 containing a hollow needle 8 which is connected to a vacuum pump or low-pressure chamber 9. Spring metal blades 12, 13 Fig. 1b (not shown) serve to clamp the tube, to delimit a measured area between the light-source and photo-cell and, to provide a visual inspection area (not shown). The outlet port may comprise a flexible capillary portion of the flow-cell Fig. 2 (not shown). In another embodiment Fig. 3b (not shown) the cell consists of two glass or quartz plates separated by a hollow plastics body having the required inlets and outlet. Masks for delimiting the light-beam and for preventing inaccuracies due to reflected light are provided.

Abstract: 639,242. Permanent magnets. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Dec. 24, 1947, No. 34178. Convention date, Dec. 28, 1946. [Class 35] [Also in Groups XXXIV and XXXVI] A permanent magnet damping assembly comprises a permanent magnet 17, Fig. 2, co-operating with stationary members 19a, 19b, the gap between them being adjustably bridged to control the flux passing through the rotating metal disc 3 to be damped.

Abstract: 1,121,121. Measuring displacement electrically. FERRANTI Ltd. Aug. 20, 1965 [Aug. 21, 1964], No. 34208/64. Heading G1N. A position transducer consists of a laminated armature 13, Fig. 1, movable in a straight line over a restricted range with respect to a stator member made up of stacks of laminations 11A, 11B, situated on opposite sides of the armature, the stator having two pairs of opposite polepieces 31, 32, 33, 34, with a secondary winding 31S, 32S, 33S, 34S around each polepiece, and two primary windings 35, 36, and the armature having two pairs of polepieces 31', 32', 33', 34' arranged to co-operate with respective stator polepieces such that a signal may be obtained from the secondary windings which varies in magnitude and phase according to the magnitude and direction of axial movement of the armature. The axial separation of the polepieces of the armature differs from that of the stator polepieces, so that any movement from a symmetrical position of the armature causes the overlap area of one pair of armature polepieces and its co-operating pair of stator polepieces to increase, and the overlap area of the other polepieces to decrease. One primary 35 surrounds the secondaries on one stack 11A of laminations, and the other primary 36 surrounds the other secondaries. The coils may be assembled on insulating boards 37A, 37B carried on the stator, and the armature moves in jewel bearings 23 which are adjustable in position perpendicular to the axis, by rotation of eccentric mountings 24.

Title: Method of Producing Colour Video Signals for use in a Colour Television Receiver
Inventor: TAKAGI TOSHIHIKO
IPC: H04N9/07
Filed: 1966-07-29
Abstract: 1,160,231. Colour television. NIPPON COLUMBIA K.K. July 29, 1966, No.34227/66. Headings G2A and G2J. An image of a coloured object is recorded on mono-chromatic film as a series or pattern of stripes, the stripes corresponding to the primary colours of the object. This is then used for producing colour video signals for colour television. As shown, an image of an object 101 is focused by an objective lens 102, through a filter 130 and a relay lens 104, on to a sheet 105 of monochrome film. The filter 103 is a composite of two layers 103o and 103b, shown in more detail in Fig.2. Layer 103a comprises alternate stripes W (which transmit light of all wavelengths) and -R (which intercept red light). Layer 103b comprises alternate stripes W (as before) and -B (which intercept blue light). Thus the object 101 is recorded on the mono-chromatic film 105 in the form of a series of stripes, the degree of exposure of each stripe corresponding to the primary colours comprised in that particular stripe on the original object. The stripes are such that when the image on the film is projected on to a photo-electric conversion device, the scanning beam of the said device sweeps transversely across the stripes (direction h). The width and number of the stripes are determined in relation to the line scanning frequency of a television image pick-up tube, and a video signal of a particular frequency is produced containing the components of colour information, which are analyzed and reproduced by the apparatus described in Specification 1, 160, 232. The lens 104-may be omitted, and the filter 103 located in direct contact with the film Fig.3 (not shown). Fig. 4 (not shown) is an alternative type of filter, comprising stripes in sets of four (W, R, G, B), which transmit respectively white, red, green, and blue light. Fig.5 5 (not shown) is an arrangement in which one set of filter stripes is set at an angle to the other. This has the effect of changing the frequency of the band pass filters of the video signal generating apparatus, which would otherwise require changing the width of the stripes.
