Filed: 1963-09-02
Abstract: 974,270. Connecting-rods; pistons. CATERPILLAR TRACTOR CO. Sept. 2, 1963, No. 34579/63. Heading F2T. A piston 10 has a central boss 1<SP>6</SP> depending from its head and is connected to its connecting-rod 11 by a T-shaped gudgeon pin 13 secured by a retaining pin 15.

Title: Lateral axis control means in aircraft control systems
IPC: G05D1/02
Filed: 1973-06-20
Abstract: 1434076 Automatic control of aircraft SPERRY RAND CORP 20 July 1973 [30 Aug 1972] 34610/73 Heading G3R In an autopilot the lateral axis (yaw) is controlled by a system comprising a directional reference (heading gyro) coupled to the rotor of a synchro control transformer whose stator is fixed to the aircraft and is connected to switching and demodulating means whereby a triangular wave D.C. signal is produced whose leading and trailing edges correspond to linear variations in aircraft heading between predetermined headings (which correspond to the peaks of the triangle), means for deriving a rate of change signal from the triangular D.C. signal, and means for tracking and holding the rate signal for a predetermined time when the slope of the D.C. signal changes over thereby to eliminate transients at these points. The transformer stator produces three phase sinusoidal signals Fig. 2a, (not shown) as the aircraft rotates as a modulation on 400 Hz energization applied to the rotor. The relative amplitudes of the three phase signals are compared (after demodulation) to operate a switching circuit using logic elements Fig. 1a, (not shown) whereby the substantially linear part of each sine wave is switched in turn to provide the single D.C. triangular wave. This is applied to terminal 21 and is differentiated and filtered at 22 to produce the heading rate signal whose polarity depends upon the direction of slope of the signal 21. The negative values are inverted at 23 by switching F.E.Ts 73, 74, using signals from the circuit of Fig. la. To block the switching transients the inverter output is connected to tracking and hold circuit 24. Normally, this passes the signal unchanged but its value is tracked by capacitor 90 which thus holds the value when a switching F.E.T. 88 is opened by a signal at the instant of change over of slope. 88 is turned on again after a time deter-  mined by a "one shot" multi-vibrator in Fig. 1a. The output of 24 is filtered by "washout" 25 to remove low frequency, i.e. steady turn, components and is fed to the rudder servosystem 28, which may be as described in Specification Co-pending. The control signal is progressively limited by switching it to earth at a variable mark space ratio by transistor 83 as the aircraft bank angle goes from 43 degrees to 47 degrees or as the roll rate progresses to 8 degrees per sec. Signals to this effect are supplied on lines 80 and 84 respectively and are compared with a triangular waveform in differential amplifiers 81. The control may be disengaged by a signal at 85. The heading signal on 21 is also applied to the roll axis of the autopilot via the circuit 27; this may be turned off by removing a "heading hold" signal on transistor 99 and this inserts a feedback amplifier 97 (by transistor 98 turning on) across heading amplifier 95 so that the combined signal applied to output amplifier 100 is zero. Capacitor 101 holds the feedback voltage to provide smooth turn on when "heading hold" is engaged.

Abstract: 490,988. Drums. DEANS, C. F., and BUSBY, A. E. Dec. 17, 1937, No. 35005. [Class 88 (ii)] Snare-wires, pads or other tone-modifying devices are moved with respect to the head of a drum by means within the drum operated by a pedal control which is remote from the drum, being connected by a Bowden wire or like mechanism. In the Figure the pedal 37 is connected by the inner Bowden cable 28 to the outer end of an arm 23 on a shaft 21, and depresses a sector 24 pivotally connected at its upper end to the arm 23, and at its lower end to a guided bearer strip 18, which strip projects at each end from the casing 11 and carries the ends of the snares in housings 17. The snares are thus removed from the (lower) snare head, being re-applied by a spring 34. The pedal and Bowden mechanism are adjustable. Figs. 4 and 5 (not shown) show means for moving snares or a pad with respect to the under face of the (upper) batter head. In Fig. 6 (not shown), the pedal is mounted remote from the drum-stand, in a box which rests on the floor. The outer end of the spring 34 may be carried by a crank arm, Fig. 7 (not shown), by the angular displacement of which the spring may be thrown out of action so that the snares will remain in their displaced position.

Abstract: 941,804. Magnesium alloys. MAGNESIUM ELEKTRON Ltd. Oct. 3, 1961 [Oct. 18, 1960], No. 35680/60. Heading C7A. A magnesium alloy contains in percentage by weight the rare earth metals and thorium together preferably not exceeding 4% and the hydrogen content being at least 80 c.c. per gram of zirconium content. The hydrogen content is obtained by heating the alloy in an atmosphere such as dry or wet hydrogen, ammonia, wet carbon dioxide, wet argon or steam at a temperature preferably between 300 ‹ and 600 ‹C. Hydriding at the lower end of the temperature range is facilitated by first shot blasting or by roughening the surface by means of a salt solution. The invention extends also to alloys within the above range, but having at least 0.4% zirconium, and not more than 20 c.c. hydrogen per 100 gm. of alloy, which are first homogenized in the absence of hydrogen at a temperature of at least 625 ‹C. for at least 24 hours, or possibly at 600 ‹C. for 100 hours, and are then hydrided.
