Title: Improvements in or relating to aircraft control systems

IPC: G05D1/12
Filed: 1958-11-11
Abstract: 850,249. Automatic steering control systems. WESTINGHOUSE ELECTRIC CORPORATION. Nov. 11, 1958, No. 36204/58. Class 38(4). In an aircraft automatic control system pitch and yaw error signals are derived from a radar system and separately amplified before application to the pitch and yaw channels of an automatic pilot, the gains of the two amplifiers being automatically increased when the sum of the pitch and yaw signals falls below a predetermined value. In Fig. 4, D.C. signals representative of errors in pitch and yaw of an interceptor aircraft relative to a target aircraft are chopped and respectively applied to electronic A.C. amplifiers 34, 341, the outputs of which control, through electronic demodulators 36, 36<SP>1</SP> and electronic D.C. amplifiers 40, 401 the appropriate channels of an automatic pilot (not shown) for the interceptor aircraft. The chopped pitch and yaw signals are also applied to an electronic adding circuit 46, the output of which operates an electronic relay unit 48 to increase the gain of amplifiers 34, 34<SP>1</SP> if the sum of the pitch and yaw signals falls below a predetermined value, e.g. when the interceptor aircraft is on course towards the target. At the same time relay unit 48 introduces resistancecondenser integrating circuits 38, 38<SP>1</SP> into the pitch and yaw control channels to increase accuracy. When, later, the range of the target aircraft falls below a predetermined value a signal (not shown) from the radar system automatically operates relay unit 48 to short out signals applied to the yaw channel so that the final control of the aircraft is by pitching only to facilitate firing of rockets.

IPC: D01H13/16
Filed: 1928-12-08
Abstract: 326,240. Juliß, J. Dec. 8, 1928. Spindle-driving apparatus; stop-motions.-In doubling and twisting machines provided with stop-mechanism for the spindles operating automatically upon breakage of individual yarns or of the thread, the spindle clutch comprise a disc 67, Fig. 5, secured to the spindle and a disc 74 slidable thereon under the action of springs 76, 78, which are connected to pins 71, 73 integral with the disc 74 and rest on the upper surface of the disc 67, so that normally the discs are maintained in contact with a friction disc 65, Fig. 6, connected to the driving-wheel 56, Fig. 1, but are separated, as shown, when the cap 50 is depressed by a lever 45 connected with the stopmechanism. The disc 65 has a toothed periphery engaging a correspondingly toothed surface 64 in the wharl or gear wheel which rotates on ball bearings 57, 58 carried by a fixed sleeve 51. The lever 45 is operated by the vertical movement imparted by a spring 15 to the depending support 14 of a frame 5, which is slid horizontally, so as to be freed from a retaining catch 18 to permit this movement, by means of a cam 4. The frame 5 is provided with arms 6, 7 respectively carrying the top delivery roller 9 and the detectors 21 of the broken-end stop-mechanism. If an end break its detector is released and the weighted part 25 thereof falls and is engaged by the cam and the frame 5 moved horizontally. If the thread break in front of the rollers the detector lever 34, 35 pivots and an adjustable abutment 36 thereon releases a rod 38 provided with a catch similar to the part 25 so that the frame 5 is similarly operated. The mechanism may be operated manually by shifting the frame 5. The spindle is mounted in a tube 53 carried in a hemispherical bearing 55 in the sleeve 51 so as to be capable of oscillation controlled by springs 61, 62 bearing upon inclined seats. Lubricant is supplied to the sleeve 51 from a reservoir 82 and passes by suitable orifices to the spindle, the bearing 55, and the wharl bearings.

Abstract: 835,542. Knitting. POWELL, R. C. May 25, 1956 [May 26, 1955], No. 36478/59. Divided out of 835,541. Class 74 (2). Loops are drawn over generally vertical edges 74 lying above downwardly - directed sinker hooks 75 and, when stitch formation is at least substantially complete, are caused to pass below the hooks on to edges 76 spaced a short distance from the hook in the direction of the other end of the sinker. Slack is thus provided which will diminish the stress in stitches when knitting proceeds on some needles only in knitting seamless gloves on a parallel machine. The sinkers are, during loop drawing, either fully depressed, or elevated only enough to prevent the yarn sliding over the extended top of the sinkers; and they are subsequently elevated fully, to cause the sinker loops to slide below the hooks.

In a unidirectional amplifier comprising a plurality of cascased units each of the negative resistance repeater type and thus capable of effecting amplification in either direction, the units are energized to be periodically operative only, the period for which each is operative being delayed with respect to that of the immediately preceding unit while there is inserted between each adjacent pair of units a relay circuit whose delay time equals the delay between the energization of the two units whereby signals passing through the amplifier in the forward direction are amplified by each of the successive cascaded units while signals passing in the reverse direction are not so amplified and are consequently attenuated. Fig. 7a shows a circuit comprising three repeater units N1, N2, N3 energized from a three-phase power source So having outputs as shown in Fig. 8. Delay units D1, D2 each having a delay T, are inserted between the units N1, N2 and N2, N3 respectively. The input signal is applied to the amplifier through a low-pass filter F1 and the output is passed through a low-pass filter F2 which removes the component due to the power source. Circuits comprising a different number of repeater units and a different number of phases in the power supply are also described. Tunnel positive-gap or double-base diodes may be used in the construction of the negativeresistance repeaters. Fig. 5a shows a circuit employing tunnel diode D1 and exhibiting a negative impedance between terminals a, b, while Fig. 5b shows a similar circuit employing positive-gap diodes. Figs. 6a 6b and 6c (not shown) illustrate respectively #-type, T-type and bridged-T-type combinations of tunnel and positive-gap diodes which may also be used.

In order to facilitate the throwing of yarn on to a bobbin, a stationary guide 42 arranged to receive yarn coming from a ring traveller 12 has a guiding surface extending inwards from a point further from the axis of the bobbin 27 than the traveller 12, so that yarn engaging the guide 42 is urged inwardly as the traveller 12 moves downwards and is caught by a rotary bobbin support-plate 24. On removal of a full bobbin, the yarn is passed from the feed roll 34 to a balloon guide 38, thence to an upper guide 44 and back to the feed roll 34. After an empty bobbin 27 has been placed on the spindle, the yarn extending between the guides 38,44 is manually drawn through the ring 13, engaged in the traveller 12 and slipped under the curved fingers 45,45a of the guide 42, the bobbin 27 and its plate 24 being kept stationary during this operation. The fingers 45,45a are directed upwardly and each finger is bent to provide yarn seats 47 that are located at a greater distance from the spindle axis than the radius of the plate 24, which radius is greater than that of the ring 13. When the ring 13 is moving down, the plate 24 is allowed to rotate and the yarn is pulled from the seats 47 into engagement with the edge of the plate 24 where it is caught in a slot and broken. Reference has been directed by the Comptroller to Specification 748,327.
