Title: Improvements connected with slats for aircraft
IPC: B64C9/22
Filed: 1934-12-27
Abstract: 441,103. Controlling slot-forming slats for aircraft. BLACKBURN AEROPLANE & MOTOR CO., Ltd., Seaplane Base, and BUMPUS, F. A., Elloughton, both in Brough, near Hull. Dec. 27, 1934, No. 37059. [Class 4] An aircraft having slats which operate automatically during flight is provided with a locking device which permits the slats to be locked in the closed position .and which is adapted to be operated to lock the slats in the closed position only when the aircraft is on the ground. Mechanism is provided for automatically unlocking the device by operations performed prior to, or in the take-off, or during flight, if it has not been unlocked by hand. The slat a is pivotally mounted by links a<1>, a2 near the nose of the wing and a tubular member c connected to the link a<2> and extending in the direction of the wing span is engaged in the locked position of the slat by a recess in a bell-crank lever b pivoted at b on the spar of the wing. The arm b<2> of the bell-crank is connected to a spring-loaded device d connected at d<1> to the frame of the wing. Movement of the end b<3> in the counter-clockwise direction to unlock the slat, compresses the spring until a dead centre position has been reached after which the spring device expands to move the bell-crank and retain it in an unlocking position against a stop f. The slats may be unlocked by the operation of the lever controlling the ailerons. A cable e passing round a pulley e<2> is splayed into portions e<4>, e<5> connected to a yoke e<3> rigid with a rotatable shaft e<8> which carries a yoke e<10> having its ends connected by cables e<11>, e<12> to the lever, (not shown), controlling the ailerons. The locking device may be released by movement of the tail wheel or skid under spring action as the tail of the aircraft rises prior to flight.

As shown, Fig. 1, a cylindrical workpiece W, being machined by a grinding whell G, is gauged by a device 10, having feelers 10a diametrically contacting the workpiece. The output of the gauge is derived from a differential transformer and fed through an amplifier 11 to a synchronous rectifier providing an analogue signal indicating, by magnitude and polarity, the displacement of the feelers 10a. The analogue signal is fed to a null-point compensator 13 for a signal generator 14 controlling the feed-movement of a wheel head 16 through a controller 15. The output of a post-process gauge 20 through a synchronous rectifier 22 and an A-D converter 23 is fed to a calculating device 30 which provides a compensating signal, through a pulse generator 35 to the null-point compensator 13. The device 30 comprises a circuit 32 calculating the trend in a predetermined number of post-process measurements stored in a memory 31 to obtain an estimate of the trend on the future. A circuit 33 discriminates between upper and lower limits and decides the necessity for null-point compensation which is calculated in a circuit 34. The use of a initially programmed computer is disclosed as is provision for a number of workpieces awaiting post-gauging. The null-point compensator, Fig. 2, comprises a D-A converter having an operational amplifier 13a to an input of which is connected a ladder network 13b, stages of which are connected to earth or a source of reference voltage V s  by a plurality of switching transistors S0-S16, the bases of which are connected with binary-weighted output terminals of a reversible counter 13c.

Abstract: 1524686 Thermal switches RANCO Inc 25 Sept 1975 [30 Sept 1974] 39255/75 Heading H1N A thermal switch comprises a movable contact 82 supported on a resilient blade 84 for movement relative to a fixed contact 80 and a thermally responsive snap acting diaphragm 92 for moving the blade 84 via a lever 110 which has a part cylindrical bearing surface 140 engaging a corresponding surface formed in the wall of the switch housing. In one embodiment, the fixed contact 80 is connected to a U-shaped member 30 having one of its legs extending from the housing 26 of the switch to define one terminal 78 and the resilient blade 84 is riveted to a similar U-shaped member 28 defining another terminal. The diaphragm 92 comprises a snap acting disc forming part of a fluid chamber 88 connected to a capillary tube 94 which leads to the appliance whose temperature is to be sensed. Above a predetermined temperature, the diaphragm 92 moves with a snap action to pivot the lever 110 about a hinge axis 148 which in turn deflects the blade 84 away from the fixed contact 80. The blade 84 can only be moved back into the closed switch position by a reset pin 160 which acts on the blade 84 via a leaf spring 162 riveted to the terminal 28. The diaphragm 92 is snapped back to its initial position by the lever 110 when the blade 84 is moved by the reset pin 160 to the closed position which can only occur if the temperature of the appliance is below the predetermined level. The portion 122 of the lever 110 which engages the blade 84 wears away by sliding along the blade 84 during opening and closing of the contacts 80, 82 so as to compensate for the normal erosion of the contacts 80, 82 thereby preventing a change in operating temperature of the switch. In another embodiment (Fig. 9, not shown) the reset pin 160 is omitted and the diaphragm 92 snaps back to its initial position when the temperature falls below the predetermined level.

[Also in Division B8] In a method and apparatus for coating and decorating confectionery, specifically chocolates, chocolate blanks 2, e.g. made from a nut mixture and having had their bases already dipped in chocolate converture, are conveyed, on a travelling perforated belt 1, through a falling curtain 6 of heated liquid chocolate converture issuing from one or more perforated tubes 5 of a coating device 4, and are thus completely covered with converture. The resulting coated chocolates 7 are then passed through a pre-cooling passage 8 to solidify their bases and their coatings. The precooled chocolates 7 are deposited on an endless, travelling belt 12, and carried past an optional straightening or aligning comb 14, and then underneath a decorating device 13 having nozzles, from which thin threads or pipings of a heated decorating mixture are dispensed on to the chocolates. The nozzles may be attached to a bar, to which loop-shaped, zig-zag or arcuate movements may be imparted, to form the extruded threads into corresponding decorative patterns. After the device 13, a comb formed of wires bent at their free ends may be disposed, so that said free ends make contact with the decorated chocolates and produce further decorative effects. A brown decorating mixture, such as a milk-chocolate and butter mixture, may be dispensed on to chocolates on one half of the belt 12, and a white mixture, e.g. comprising cocoa-butter, sugar and milk, may be dispensed on to chocolates on the other half of the belt. Two decorating devices 13 may be arranged in series. The coated and decorated chocolates are transferred from the belt 12 on to a travelling belt 15, which carries them through a final cooling passage 10. Stripping blades may contact the belt 12, as it passes to a driving roller 27, to scrape off any deposited decorating mixture into a collecting bowl, from which the mixture may be returned, through a heater, to the device 13. A collecting bowl may be provided to collect brown scrapings and another bowl may be provided to collect white scrapings.
