Title: Thermally-operated Actuators
IPC: G05D23/275
Filed: 1968-11-25
Abstract: 1,194,959. Temperature responsive actuating elements. LANDIS & GYR A. G. Nov. 25, 1968 [Nov. 28, 1967], No. 55819/68. Heading G1D. A thermal actuator comprises an evaporator 7 with a liquid filling 18, a heater 4 surrounding the evaporator 7 and connected to a control 1, a pressure chamber 13 connected by a tube 10 to the evaporator 7 and containing a bellows 14 with an end closure 15 which is displaced on vaporization of the liquid filling 18 against the action of a return spring 17, a body 11 of material which is not wetted by the liquid filling 18, contained within the evaporator and formed with capillary cavities permanently filled with vapour, and a flow throttle in the form of a porous ceramic or metallic filter 12 or by a single flow construction disposed on the flow path of the liquid between the evaporator 7 and pressure chamber 13 to prevent too sudden a return flow of cooled liquid to the evaporator 7 giving rise to a sudden decrease of vapour pressure therein. The evaporator is cylindrical and the heater 4 extends for a greater length thereon than the interior space of the evaporator. The body of material 11 is disposed at the hottest part of the evaporator. Heat conduction along the tube 10 will cool the lower end of the evaporator 7, and if desired the heater 4 may be arranged to provide this effect e.g. by an uneven distribution of the coils of the heater around the evaporator body. A suitable material for the body 11 is polytetra fluoroethylene or a fluorinated methacrylate polymer. A mixture of water and alcohol may be used for the liquid filling 18.

Title: Improvements in or relating to an Aircraft Collision Avoidance System
IPC: G01S11/08
Filed: 1968-11-25
Abstract: 1,194,470. Radio navigation; radio signalling. BENDIX CORP. 25 Nov., 1968 [28 Dec., 1967], No. 55867/68. Headings H4D and H4L. In an aircraft collision avoidance system each craft carries a clock (e.g. an atomic clock), all the clocks keep the same time, each craft is assigned a time slot within which it transmits a collision avoidance message, and each craft generates a plurality of frequencies controlled from its clock one of which is utilized for its message transmission. In the embodiment each time slot period, Fig. 1, is 1172 microseconds and an aircraft transmits once in every five seconds; each transmission consists of a C.W. pulse 10, the leading edge of which at a receiving craft is compared with its clock to give range and is also utilized to give range rate by Doppler shift, a guard time of 170 microseconds to eliminate ground reflections, a pulse 14 the timing of which corresponds to altitude rate, a further guard time, and a pulse 18 the timing of which corresponds to altitude. In the apparatus on a craft, Fig. 2, radio frequencies # 1 , # 2 , # 3,  # 4  are generated by a frequency synthesizer controlled by a caesium atomic clock which includes counting circuits; gate enabling pulses are produced, each of a period equal to a slot period, sequentially on lines 30A... 30D and the output of OR gate 31 is applied to AND gate 32 which is enabled by a pulse on line 30E, such pulse defining the time slot assigned to the craft. In the receiver corresponding local oscillators 54, 56, 58, 60 are provided and assuming, for example, that a message is received on frequency # 1 , gate 62 will give rise to an I.F. signal output to decoder 64 which generates range, range rate, altitude and altitude rate signals; similarly gate 64 is opened during the next time slot. Computer 76, after utilizing range/(range rate) or range criteria to determine that a collision threat exists, compares the intruder's altitude and altitude rate with that of "own" craft to determine whether at the predicted time of closest approach the intruder will be within a relative and predetermined vertical separation: if so, an appropriate manoeuvre command signal issues.

A device for feeding articles such as sweets from disorderly array into single file, comprises an article-feeding band 16 arranged to be driven at a predetermined linear speed, an articlereceiving band 23 arranged to be driven at a linear speed higher than that of the band 16, a diagonal deflector plate 21 arranged over the article-feeding band 16 to guide the articles towards one side of that band so as to pass on to a side portion the band 23, and a deflector belt 26 arranged for movement diagonally of the band 23, one lap of which forms one side of a guide channel 32, so as to guide the articles towards the guide channel as they are received by the band 23. The band 16 is fed by a more slowly running band conveyer 12. A spring- loaded tongue 33 tends to align sweets 11 when they arrive at the channel 22 with their major axes perpendicular to the band 26. The channel 22 feeds the sweets to an endless band 36 forming the base of a further channel 34 leading to a wrapping machine (not shown). A photoelectric unit 41 initiates starting and stopping of the belt 12 according to the presence or absence of gaps in the flow of articles on the belt 36.

Abstract: 1451502 Clutch control AISIN SEIKI KK 6 Dec 1973 [21 Dec 1972] 56724/73 Heading F2L  . In a clutch release mechanism in which a self-centring clutch release bearing assembly A is moved against clutch release means (comprising the inner periphery of a diaphragm spring 4) by pivoting of a lever 12 by a push rod 11 of a clutch release cylinder 10, the cylinder 10 incorporates a spring 2 which provides a force to maintain the bearing A against the spring 4 when the clutch is engaged (the force being too small to disengage the clutch) and so prevents change of the central position of the bearing A. As shown in Fig. 2 the bearing 14 is held against a friction surface 18 by a wavy spring 17 and is radially movable against this friction force to provide the selfcentring action. The spring 2 may be replaced by a force from a releasing cylinder.

Abstract: 1336878 Relling threads; self-tapping fasteners; forging RESEARCH ENG & MFG Inc 10 Dec 1970 [19 Jan 1970] 58782/70 Headings B3M B3N and B3H A self-thread-forming fastener is produced by rolling a blank between two opposed dies, the blank having a main shank portion 30, Fig. 3, of circular cross-section, a leading end portion 32 of arcuate lobular cross-section, and a tapered section 34 between the other two portions. During rolling the dies remain equidistant from the axis of the shank portion, while the leading end portion is subject to intermittent rolling pressures which deflect the end in relation to the shank axis. The end portion may have three or five arcuate lobes, Fig. 13, or may have a circular or elliptical portion 92, Fig. 18, disposed eccentrically to the shank portion. The rolling dies, which may be flat or rotary, have flat sections 64, Fig. 11, which engage the end portion of a blank. As each lobe on a blank comes into contact with such a section, the lobe is urged away from the die. The axis 70 of the leading end portion is thus deflected cyclically during rolling between positions 72. In place of the integral sections 64 of the die, separate inserts (Figs. 24, 25, not shown) may be provided. The thread profiles on the leading and tapered portions vary according to which kind of die is used.  The blank, Fig. 3, is formed from a length of cylindrical stock in a heading press, Fig. 14. The dies 50 and 46 of the press are shaped to provide an integral head and washer 12 at one end of the blank, and an arcuate lobular section at the opposite end. An ejector 52 removes the finished blank from the press.
