Title: Apparatus for measuring distortion lebels in binary element  sequences
IPC: H04L12/26
Filed: 1971-05-07
Abstract: 1315892 Measuring distortion of pulses SIEMENS AG 7 May 1971 [8 May 1970] 13670/71 Heading G4H Apparatus for measuring deviations from a required length of pulses in a train corresponding to successively transmitted single bits utilizes phase measurements between a clock source and one of two frequency dividers displaced with respect to the source by the amount a change in polarity of an input pulse leads or lags that of a clock pulse. As shown, a series of reference pulses T1 together with a series of pulses E to be examined are applied to a synchronizing circuit SE and a pulse shaping unit ES respectively, the pulses T1<SP>1</SP> being initially synchronized with the input E and passed simultaneously to 3 counters ZI, ZII, ZIII each comprising two series decade counter units Z1, Z2, the counters acting as frequency dividers delivering outputs T2, V1, N1 respectively which are further pulse trains of a wavelength 100 times greater than T 1 and of a pulse length half that of the nominal pulse in E. The output L of the device ES is a series of unidirectional spikes emitted at each polarity change in the pulse train E and applied to both gates GI, GII, the other inputs at GI being the signal T3 which is the inversion of T2, and the inverted output VI of counter ZII, while to gate GII there is the inverted output N1 of counter ZIII and the signal T2. In the event of a pulse E rising at a later time than a pulse of T2, a reset pulse is emitted by gate GII to reset the output of counter ZIII to the beginning of its present pulse, from which the counter continues to count up pulses T1<SP>1</SP> and hence is out of phase with the counter Z1 by the amount of delay introduced. Similarly, a leading pulse E activates gate GI associated with ZII. The phase differences are effectively stored in the counters ZII, ZIII and after some difference has been introduced, the gates GI, GII will only produce outputs when a phase difference in excess of that already stored is monitored. Read-out is effected via gates GIII-GV. The inputs to GIII are T2, the inverted output V2 of counter ZII, an enabling signal on line 3 of a measurement generator MG and an enabling signal produced by the placing of switch S in an appropriate position, the output of GIII being produced for a duration corresponding to the phase difference stored in ZII and causing pulse T1<SP>1</SP> to be counted at ZS via gate GV for this interval, the count at ZS being the percentage distortion. Gate GIV is enabled with switch S in a different position and both may be enabled to give a total distortion measurement at ZS. The counters ZIZIII may be reset for a new measurement cycle via signals on lines 1, 2 of MG received at inputs 2.

A filler cap for a car radiator comprises a first valve for relieving pressure built up within the radiator and a second valve allowing entry of air to the radiator if its internal pressure drops below atmospheric pressure. As shown, the first valve has a plastics cylinder 2, diaphragm 19, and projection 20 which seats on a closure member 8. When the pressure in the radiator overcomes the loading of the diaphragm, projection 20 is lifted from its seat. A throughway 12 in the closure member 8 carries a valve 14. A flap 17 of the valve opens to admit air when the pressure inside the radiator is below atmospheric. The cap, which is closed by a vented member 4, may be attached to the filler neck of a radiator by means of a bayonet joint or a coarse pitch thread formed on its body 10. In a modification, the first valve is a spring-loaded member 4 obturating a central passage in a fixed member 5, Fig. 10, and the second valve is formed by a flexible flange 15 on the fixed member closing apertures 14 in a rigid annular member 6. A spring 21 seats a washer 39 on the cap body 36 against the filler neck 37, and the overflow pipe extends laterally from the neck. In other modifications having generally similar valve arrangements to that of Fig. 10, the outflow passage is on the axis of rotation of the valves, Figs. 6-9 (not shown).

Filed: 1935-05-13
Abstract: Alloys containing 50-75 per cent of gold, 40-15 of platinum and 5-25 of palladium, more than 5 of palladium being present when there is more than 65 of gold, are hardened by annealing them at a temperature above 1005 DEG  C. but below their melting point and then either quenching and reheating to 500-750 DEG  C. for a time sufficient to produce the desired hardness, e.g. 1/4 to 1 hour, the subsequent quenching beng followed, if desired, by cold working or cooling slowly to a temperature within the range 500-750 DEG  C. and then quenching.  The hardening may be carried out by rolling an ingot, subjecting it to a prolonged homogenizing annealing, e.g. for 1-2 hours, then to short anneals, e.g. for 1-5 minutes at intervals in the rolling process, each anneal being followed by quenching and then to a final heating at 500-750 DEG  C. for a time sufficient to produce the desired hardness, e.g. 1- 1/2 hour.  The amount of reduction in thickness produced by the rolling is from 20 to 90 per cent.  In an example, an alloy contains 70 per cent of gold, 20 of platinum and 10 of palladium.  Specification 361,893 is referred to.

Title: Control apparatus for aircraft
Inventor: SUMMERLIN FREDERICK ARTHUR
IPC: G05D1/00
Filed: 1957-05-02
Abstract: 855,733. Automatic control systems for aircraft. SPERRY GYROSCOPE CO. Ltd. April 25, 1958 [May 2, 1957], No. 14027/57. Class 38(4). In an aircraft control system a signal is produced when deflection of a control surface from its neutral position exceeds a value which varies only with air speed as measured by an air speed responsive device. In Fig. 1 deflection of an aircraft rudder I under the control of an automatic pilot (not shown), operates a potentiometer 13 arranged in a D.C. bridge circuit. If rudder deflection exceeds a predetermined value in either sense the output of the bridge circuit provides sufficient energization to a winding 18 to operate a polarized relay 19, thereby rendering the automatic pilot inoperative by deenergizing a relay 24 controlling the supply to a terminal 27 for the automatic pilot. A bellows 42 associated with a pilot tube adjusts a printed circuit resistor 16 so that the rudder deflection required to operate relay 19 decreases in steps with increase in air speed. In the similar arrangement provided to limit elevator deflection an insulated bar 46 disconnects the wiper of elevator potentiometer 13<SP>1</SP> at a predetermined downward deflection of the elevators which is independent of air speed, and air speed adjusted resistor 16<SP>1</SP> is so connected that the permissible upward deflection of the elevators decreases one step at slow landing speeds. Use of an asymmetrical potentiometer associated with the elevators to produce different limiting deflections in each sense is referred to. An arrangement (not shown) similar to that provided for the rudder, but with only one step of variation with air speed, is provided to limit aileron deflection. The relays may operate a warning device instead of rendering the automatic pilot inoperative and may also be operated by voltage from a stall warning system.
