Title: Aquatic apparel
IPC: B63C11/04
Filed: 1967-04-13
Abstract: 1,144,718. Protective clothing. UNITEX. 13 April, 1967 [21 April, 1966], No. 16995/67. Heading A3V. A wet suit or partial covering for aquatic wear comprises a strip of flexible stretchable material, with at least one opening at each end, which is wound under tension round a selected part of the body and is anchored at each end by passing an arm, leg &c. through each opening. Suitable material is foamed neoprene. A trunk strip 10, for example, has one or two leg openings and one or two arm openings. A leg strip may have a portion of increased width midway of its length. Several strips are used for complete coverage, optionally in combination with a short vest or trunks. The material around the openings is reinforced e.g. by local impregnation with e.g. rubber or synthetic plastics or by making the ends of each strip of material of greater tensile strength than the rest of the strip.

Title: Flight control system
IPC: B64C13/18
Filed: 1969-04-01
Abstract: 1,260,223. Automatic control of aircraft. UNITED AIRCRAFT CORP. April 1, 1969 [May 29, 1968], No. 17059/69. Heading G3R. In a closed-loop system for controlling the attitude of an aircraft about an axis, signals dependent on rate of turn and attitude about the axis control first means operating an appropriate control surface to a limited extent, the attitude signals also controlling second means in series with the first means at a limited rate. As shown, with switch 46 closed to disable a synchronizer 50, signals dependent on deviations of aircraft attitude, e.g. the roll or pitch attitude of a helicopter, derived from a gyro 42, are applied through amplifiers 52, 68 to operate a hydraulic valve 70 controlling the position of a hydraulic positional follow-up servomotor 74 the rate of operation of which is limited by a flow limiter 72. Servomotor 74 stabilizes the attitude on a long term basis by adjustment of the appropriate control surface through coupling 76 and a differential mechanism 26. To maintain a desired speed, the output of a Doppler radar unit 44 is compared with a signal representing the desired speed from a potentiometer 56 and any difference, with an integral component added at 62, is applied at 60 to modify the stabilized attitude and thereby correct the speed. The signal from integrator 62 may be nulled and the speed error signal introduced by a fade-in circuit 58 without shock when switch 46 is closed to introduce the automatic speed control. The limited rate of operation allows time for changeover to manual control by the pilot before a hard-over condition is reached under fault conditions. Short term changes of attitude are detected by a rate gyro 12 signals from which are applied through an amplifier 16 to operate a hydraulic valve 18 controlling the position of a hydraulic positional followup servomotor 20 which stabilizes the attitude by modifying control surface position, through differential mechanism 26, to an extent which is limited mechanically at 22. Attitude deviation signals produced by gyro 42 are also applied through a signal limiter 84 to operate servomotor 20 so that a limited quick response is provided for short term deviations detected by gyro 42. When switch 46 is opened to disable control by gyro 42 and Doppler radar 44, a unit 48 renders an integrator 34 effective to add an attitude deviation component to the signals from rate gyro 12. Under these conditions if it is desired to change attitude, a control column 40 is operated to adjust the control surface mechanically and a signal applied through a differentiator 36 to cancel any opposition integrator 34 would otherwise produce.

Title: Rotor and blade for rotorcraft
IPC: B64C27/41
Filed: 1951-07-24
Abstract: 718,710. Rotary wing aircraft. DOMAN HELICOPTERS, Inc. July 24, 1951 [Sept. 1, 1950], No. 17544/51. Class 4 A blade for a rotary wing aircraft in which the operating speed of the rotor in revolutions per minute and any multiple thereof each constitute an exciting frequency, comprises an aerodynamic portion, a spar attached at least to the inboard end of the aerodynamic portion and projecting therefrom the spar having a flexibility such that the ratio of exciting frequency to the natural edgewise mode two frequency of the blade including the spar is approximately 1.3 or greater, the aerodynamic portion of the blade including, if desired, a tab in the trailing and/or the leading edge, at least one of said tabs having at least one transverse slot to increase the flexibility of the aerodynamic portion. The edgewise mode two frequency is the bending of a blade supported in a fixed mounting wherein the major part of the bending takes place in the spar because of the much greater rigidity of the aerodynamic portion of the blade in the edgewise direction. The rotor head is of the type described in Specification 639,572 and each blade is secured to the hub for pitch change movement by a spar 12 which is formed with a flattened end for attachment to the aerodynamically faired portion 25 of the blade by bolts 26. These bolts secure also a pair of spaced plates 29 which carry spaced rings 31, 32 apertured so that normal vibrations do not bring the spar in contact therewith. If excessive deflection of the spar occurs however, first the ring 31 and later the ring 32 come into contact with the spar so that the spar is restrained by the plates 29, which may be further stiffened by the provision of flanges 33. The rings 31 and 32 may be resilient to improve the damping qualities of the arrangement. In an alternative embodiment (Fig. 4, not shown) the spar 12 carries internally an outwardly extending co-axial member rigidly secured to the end of the spar and formed with rings which, as the spar deflects, engage the interior surface of the spar and restrain it from further deflection. Root fairings are provided to ensure that no loss of area of the blade occurs. Leading edge tabs 47 and trailing edge tabs 45 are fitted to the blade portion 25 in order that the characteristics of the blade may be adjusted to control the modes of vibration of the blade in a plane normal to the rotor disc, the tabs being slotted to render them flexible and in order that they may be set to a desired position.

Abstract: 807,984. Pulverized fuel burners. BAB.. COCK & WILCOX Ltd. June 3, 1957 [June 5, 1956], No. 17608/57. Class 75(1) In a burner having a primary air and pulverized fuel inlet duct 17 directed tangentially to a curved peripheral wall 21 of an inlet chamber 16 and a discharge nozzle 11 connected to the chamber at an aperture 26 formed in a side wall 23 there of, a plurality of deflector plates 46 provide an interrupted circular inner wall closely circumscribing the aperture 26 in the side wall 23 and adapted to deflect portions of the air and fuel stream towards different peripheral parts of the aperture 26. Each deflector plate 46 is concave towards the aperture 26 and its downstream end is secured to a pin 47 pivotally mounted in the side walls of the chamber radially inwardly from the free end 52 of the adjacent plates. The end of each plate first contacted by the fuel is farther from the aperture 26 than the end last contacted. Each plate is adjusted by a rod 53 which is pivoted to the convex surface of the plate and projects through the curved peripheral wall 21 of the chamber. The rod 53 can be clamped by nuts to a support 55 welded to the outside of the curved peripheral wall 21. The latter is in the form of a volute and the distance between it and the aperture 26 in the side wall 23 gradually decreases from the inlet duct 17 to the cut-off point 27. The discharge nozzle 11 is frusto-conical and extends through an adjustable air register, comprising pivoted louvers, to a burner port in a furnace wall. A tube 57 extends axially through the inlet chamber 16 and the frusto-conical nozzle 11 and defines with the nozzle an annular passage of diminishing cross-section for the fuel and air. A liquid fuel atomizing burner may be inserted in the tube 57. A gas burner in the form of a ring discharging radilally inwardly may be mounted at the burner port. A view port having a glass insert 45 is mounted on the outer wall of the air supply housing. The inlet duct 17 is of rectangular section and may be positioned at an angle to the axis of the burner.

Title: Improvements in or relating to article transfer apparatus
IPC: A21B1/46
Filed: 1957-06-04
Abstract: 801,650. Transferring articles from oven conveyers; rollerways. BAKER-BERKINS, Ltd. June 4, 1957 [June 4, 1956], No. 17676/57. Class 78(1). Baking tins 50 are removed successively from the swing trays 47 of an endless oven conveyer 44 by a reciprocating pusher 49 actuated in response to the closing of a switch 56 by each tin 50 after its associated conveyer tray 47a has passed over the pusher, the conveyer track 45 being flexed suitably for this purpose. The tins are received in turn on a platform consisting of a frame 6 carrying a series of driven rollers 11. The frame consists of a pair of upper frame members 9 in which the roller spindles 10 are journalled and a pair of lower frame members 7 provided with guide elements 8 which mount the frame 6 for vertical sliding on a pair of posts 5. The frame is moved vertically between an upper tin-receiving position and a lower tin-delivery position by cam gear 20 which is driven in timed relation with the passage of the trays 47, the cam gear including a stationary cam 38 having straight portions 42 and 43 so that the platform dwells in the lower and upper positions respectively for a period sufficient to discharge or receive the tins. The cam 38 co-operates with a follower roller 35 connected by a drag link 27 with a rotating crank 21, the roller 35 being connected by links 29 and 33 to arms 16a, 17a, carried respectively by shafts 4, 4a. Pairs of arms 16, 17 also carried on these shafts engage surfaces 19 on the lower frame members 7 to raise and lower the frame 6. A housing 23 surrounds the cam 38 and prevents the roller 35 leaving its surface. A belt conveyer 52 is positioned to receive the tins from the rollers 11 when the frame 6 is in its lowered position. In operation, as a tin on the tray conveyer contacts switch 56 a motor is energized to start an operating cycle of the pusher 49 to push the tin on to the rollers 11, the frame 6 being in its raised position at this time. A switch 58 contacted by the pusher at the end of its return movement de-energizes the pusher-operating motor. As the frame 6 commences to descend a switch 60 which was caused to open 'in the raised position of the frame 6 is allowed to close, energizing another motor which drives the rollers 11 so that by the time the frame 6 has reached its lower position the tin has been delivered to the belt conveyer 52. As the frame 6 returns to its upper position to receive a fresh tin the switch 60 is again caused to open to discontinue the drive to the rollers 11.

Abstract: 497,749. Adjusting wireless apparatus; gearing. STANDARD TELEPHONES & CABLES, Ltd., and HALL, R. E. June 25, 1937, No. 17725. [Class 37] [Also in Group XXIV] A slow-motion device for variable condensers or other tuning-apparatus comprises a frictional reduction drive in series with a positive drive, the frictional drive comprising a conical driving member adapted to drive through a ball a wheel rigid with a drum which drives the tuning element positively through a cable or cables. As shown, the tuning element is driven directly by the hub 39 of a shaft 8 rigid with a disc 4 which may carry a pointer movable over a tuning scale. In the position shown in Fig. 3, rotation of the actuating knob 2 directly drives the disc 4 through the frictional engagement between flanges 3, 5. For the slow motion drive, the knob 2 is retracted, relatively to the disc 4 until the conical surface 9 of a sleeve 7, rigid with the knob 2 and rotatable on shaft 8 engages with a ball 10 carried by a stationary spring 11. Rotation of the knob 2 then drives frictionally through the sleeve 7 and ball 10 a wheel 13 rotatably mounted in a stationary cage comprising plates 15, 16. A cable 19, secured by a tensioning device to a pillar 31, Fig. 1, rigid with the disc 4, passes round guide rollers 23 .... 26 and pulleys 27, 28 mounted in the stationary cage, and is wound around and secured substantially at its midpoint to a drum 18 rigid with the wheel 13, the disc 4 therefore being driven by wheel 13 through the drum 18, cord 19 and pillar 31. The guide pulleys 27, 28 are mounted as nuts on threaded spindles to ensure the cord being applied to the drum in one layer. The angular movement of the disc 4 is limited by an arcuate slot 45 therein coacting with a rod 43 which serves to anchor the cage 14 to the panel on which the device is mounted. A flexible spring 46, Fig. 4, mounted on spring posts 47, 48, acts togglewise on the sleeve 7 to ensure good frictional contact in the drive in both actuating positions of the tuning knob 2.

Abstract: 1383849 Impregnating cables WESTERN ELECTRIC CO Inc 18 April 1972 [19 April 1971] 17842/72 Heading D1L In a method for filling the interstices of a stranded cable with a waterproofing compound the cable 2 is fed through an impregnation housing 7 comprising chambers 8 and 9, the waterproofing 'compound 3 being passed under pressure through the housing to cause, assist or retard the longitudinal movement of the cable through the housing 7, the pressure in the upstream chamber 9 being less than that in chamber 8. As illustrated the apparatus includes axially aligned inlet and outlet dies 12, partition wall 10 separating chambers 8 and 9 and transverse bores 18, 19 and 16, 17 for passing the waterproofing compound into and out of chambers 9 and 8 respectively. In operation waterproofing compound 3 is fed from supply tank 6 to inlet 16 of chamber 8 by pump 5 and passes through the chamber in the direction of movement of cable 2 to outlet 17. Outlet 17 is connected via conduit 21 to inlet 18 of chamber 9 the outlet 19 of which returns excess waterproofing compound to supply tank 6. In this way movement of cable 2 is assisted or caused by the movement of pressurised water proofing compound through the housing 7, the pressure exerted on the cable 2 being greater in the downstream chamber 8 then the upstream chamber 9. The direction of flow of the compound 3 may be reversed if retardation of the cable 2 by the viscous drag of the compound is required. Wiping die 4 is provided downstream of the cable outlet of housing 7 to remove excess waterproofing compound. Where more than two successive chambers are used to effect impregnation the pressure of the impregnating liquid is made to increase from station to station in the direction of movement of the cable.
