Title: Controls for aircraft and other vehicles
IPC: B64C13/24
Filed: 1933-01-31
Abstract: 411,220. Controlling aircraft. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, GOODYEAR, E. F., WRIGHT, J., and TREVASKIS, H., c/o Dunlop Rubber Co., Foleshill, Coventry. Jan. 31, 1933, No. 2960. [Class 4.] Dual or multi-controls for aircraft and other vehicles are connected to a common mechanism from a plurality of control positions through sheathed cables which are interconnected with a master control operable relatively to displace the sheaths and cables connected therewith to render them wholly or partly inoperative. In one form, particularly applicable to training a pilot, a fluid-pressure valve or valves 15 for aircraft wheel-brakes can be controlled through Bowden wires 11, 12 by levers 5, 6 articulated on joysticks 3, 4. The sheath of the wire 12 is anchored at 23 and the sheath of the wire 11 is connected to one end of a bell-crank lever 19 pivoted to a fixed bracket 20. The master control lever 24 is connected through a Bowden wire 27 to the end 26 of the lever 19 and its sheath is anchored in the bracket 20. Means may be provided for adjusting the lengths of the sheaths. In a modification, the brakes are operated through Bowden wires 12 by levers 6, Fig. 3, articulated on a grip 28<a>. A thumb release lever 29 having a cam surface engaging a cam surface on a lever 32 to which the wire 25 of the Bowden wire 27 is connected provides the master control. Depression of the master control causes the wire 25 to move downwardly. Specifications 379,529, [Group XXXIV], 397,895, 397,896, 397,897 ; 398,301, [Group XXXIV], and 399,622 are referred to.

Abstract: 868,554. Photo-electric measurement. GRUBB PARSONS & CO. Ltd., Sir HOWARD. Jan. 27, 1959 [Jan. 29, 1958], No. 2979/58. Class 40(3) In a device for comparing the intensities of radiation in two beam paths, the paths are interrupted at a common frequency but with a fixed phase displacement between the interruptions, the interrupted radiation being used to produce a signal representative of the resultant of the two beams, the phase angle of which relative to a fixed datum signal provides an output signal which is a function of the ratio of the energy in the two beams. As shown, Fig. 1, radiation from a source 1 is branched into two beams, one of which passes through a sample cell 6 and the other through a reference cell 7, before being focused on the entrance slit of a monochromator 13, from which selected wavelengths along each path are directed on to detecting means 14, e.g. a thermocouple. The output of the detecting means is fed, via a transformer 15, to a device 16 wherein it is amplified, amplitude limited, filtered, and impedanceconverted, and is finally passed to a phasecomparator 17 wherein it is compared with the output of a photo-electric device 18 energized by a light source 19. A chopper 20 (Figs. 1 and 2) driven by a motor 21, comprises inner and outer rings of arcuate slits, and interrupts the sample and reference beams so as to produce a relative phase displacement between the beams of preferably, and not more than 90 degrees. The chopper also interrupts the light beam from source 19 at the same frequency to produce the fixed datum signal. The output of phase comparator 17 is a D.C. voltage which operates a recorder 23. Two separate choppers may replace the single one shown, and the fixed datum signal may be produced by magnetic or electrostatic means.

Title: Record reader
IPC: G06K7/10
Filed: 1956-02-01
Abstract: 815,487. Cathode-ray tube circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 1, 1956 [Feb. 4, 1955], No. 3169/56. Class 40 (7). [Also in Groups XIX, XL (a) and XL (b)] In a data reader, the information on a travelling card &c. is projected by a short light flash on to a storage target 15 which is then scanned in columns by a cathode beam to give the output signals. In one arrangement, Fig. 1, movement of the beam from column to column is controlled by a second tube with a target on which a light pattern projected from a card 50 produces conducting and non-conducting portions as shown in Fig. 3, the output from the tube is applied as a bias to the horizontal deflection electrodes 44 to move the beam to the right and in due course the beam takes up an equilibrium position, e.g. as at 42a. The same bias voltage is applied to the horizontal deflector 14 of the reader tube. At the termination of the vertical scan, which is produced by conventional means, an impulse similar to the blanking pulse is produced by differentiator 52 and kicks the beam up to the conducting area 77 where it is deflected further to the right and then down again to another conducting path along which it proceeds to a new equilibrium position, in which the deflector voltage corresponds to the next column to be scanned by the reader tube. It will be noted that the pattern on the control card 50 may be such as to allow columns to be skipped ad lib. In its extreme right-hand position, the beam of the control tube encounters a metal strip 46 and the resulting signal drives the beam down to a non-conducting area to return it to its initial left-hand position. At the same time the vertical sweep generator for the reading tube is disabled. Alternatively reset control may be initiated by the reader tube. The output from the reader tube is applied to an accounting machine which also receives reference pulses from a generator 40 controlled by the vertical sweep generator 30. In a modification, Figs. 4 and 5 (not shown), reference impulses are generated by the passage of the beam in the reader tube over a series of horizontal bars during each vertical scan. In a further modification, Figs. 6, 7, the control tube is omitted and the reader tube is provided with a frame, comprising a number of vertical conducting bars 92 connected together and a single vertical bar 99 insulated from the rest. Initially the beam is stabilized at 109, Fig. 7, partly obstructed by the first rod 92. After scanning the first column it is sharply driven to the right as a result of the vertical flyback pulse and is stabilized in a similar position partly obstructed by the second rod. After scanning the last column the beam is kicked to the bar 99 to operate a trigger circuit 103 which momentarily disables the sweep generator 30 and paralyses amplifier 94 to enable the beam to fly back.

In one embodiment, Fig. 1, two cross-linked polymeric sheet segments 2, 3 are joined by an I-shape insert 1, containing a cross-linking agent, by the application of heat and pressure by heated platens (4), (5), Fig. 2 (not shown). The platens may be heated electrically or by steam and are cooled, before withdrawal, by the circulation of cooling water through passageways therein. In a modification, Fig. 4, the insert comprises a circular section core with outer rails 9, 10. In another modification. Fig. 5 (not shown), the insert comprises a rectangular section core (11) and two separate outer slabs (12), (13). In a further modification, Fig. 6, a single slab is diagonally disposed in the space between aligned sheet edges. Preferably, the surfaces joined are the opposite edges of a single sheet shaped to form a sleeve to be used as a covering for a pipe joint. Specified polymeric materials for the surfaces to be joined are polysiloxanes, unsaturated polyesters, polyvinyl halides, natural rubber and, preferably, polyolefins, e.g. polyethylene, poly(butene-1), various copolymers of ethylene, propylene and butene, ethylene-ethyl acrylate, ethylene-vinyl acetate, or ethylene-methyl acrylate copolymers in which repeat units derived from ethylene predominate, and blends of such copolymers with major proportions of polyethylene. Preferably, the surfaces to be joined are cross-linked by high energy ionizing radiation. Preferably, the cross-linking agent is blended with the polymeric constituent of the insert in the melt phase. Specified polymeric materials for the insert include, for the preferred polyethylenic materials for the surfaces, ethylenevinyl acetate, ethylene-methyl acrylate and ethylene-ethyl acrylate copolymers and blends of such copolymers with minor proportions of polyethylene. Examples of cross-linking agents are given, a peroxide cross-linking agent being preferred. Additionally, a "co-agent" may be combined in the insert material to maximize the number of cross-links formed through the agency of a given number of free radicals generated by the agent itself. Various co-agents, otherwise known as polyfunctional monomers, are specified. Also, the insert may contain fillers, e.g. carbon black or calcium carbonate, ultra-violet stabilizers, antioxidants and acid acceptors.
