Abstract: 1,228,382. Heat-treating elongated articles of varying cross-section. INSTITUTUL de CERCETARI TEHNOLOGICE PENTRU CONSTRUCTII de MASINI. July 1, 1968 [June 29, 1967], No.31326/68. Heading C7N. There is attached to the workpiece which is particularly a component of railway points or crossings, a compensatory part of non-magnetic material having a cross-section complementary to that of the workpiece, the two being moved together at constant speed past an induction heater and then past a cooling device. In the case of railway rails the heater may act only on the rail head, the rail then passes over a second heater which heats the base of the rail to eliminate residual stress. As illustrated rail 5 with its complementary part 6 made of hollow copper pass below heater 4, quench spray 7, discharging atomized water, and optionally spray 9 to stop self-tempering. Heater 9 then acts on the base of the rail.

Abstract: 1,228,583. Direction finding. ELLIOTT BROS. (LONDON) Ltd. 23 April, 1968 [27 April, 1967], No.. 11249/67. Heading H4D. [Also in Division G4] An electrical signal having a rectangular waveform 4A (Fig. 1) is regularly sampled to determine whether it is in its "one" or "zero" state, the results of the samples being either directly transmitted or accumulated in a register 7, the contents of which are periodically read out and transmitted. In the embodiment described each sound transducer 1A-1H in an eight-element circular array is linked via a preamplifier 2, band-pass filter 3 and limiting amplifier 4 to an AND gate 5 receiving the rectangular signal 4A, the width of the positive half-cycles of which is dependent on the relative amplitude of the frequency components of the signal received by the associated transducer. Clock pulses from a signal generator 6 are fed to each of the gates 5 so that the registers 7 accumulate pulses representing the signals 4A. The registers are sequentially read out via gates 8 to a telemetry link TL in binary form using a frequency shift keying system. A sync. signal may be transmitted. At the receiver the signals from each register are fed via an associated delay register to a summing and weighting unit (13, Fig. 2, not shown) associated with a particular sound direction. Each unit (13) receives the signals from the other seven delay registers delayed by an amount corresponding to the position of the transducer in the array with respect to the chosen direction. The output from each unit (13) is fed via a filter (15) to an output lead (16) which delivers an analogue signal representing the sound in the chosen direction.

A two-stage governor-valve for delivering speed-responsive fluid pressure to an automatic transmission on a vehicle, comprises main and auxiliary centrifugal masses 69, symmetrically pivoted about parallel axes 10, 11 on a rotating output or other shaft 5, the main mass 6 having an integral arm 12 acting inwardly on a transverse valve-spool 4 to close an exhaust outlet 3, which thereby regulates pumped fluid pressure in a supply chamber 2. In a lower speed range the main mass 6 is assisted by the auxiliary mass 9, acting on the arm 12 through a spring 7, but in a higher speed range the auxiliary mass 6 is phased out by contact with a stop-pin 8. The consequent pressure-speed curve (Q, Fig. 3, not shown) is shallower and the two curves approximate to a straight line.

Abstract: 1,257,060. One-way detents. ENGLISH ELECTRIC CO. Ltd. 17 April, 1970 [20 Jan., 1969], No. 3200/69. Heading F2E. The invention provides an anti-reverse device for rotatable spindles, especially spindles in electrical meters, e.g. watt-hour meters; the maximum degree of reverse movement permitted is a little less than one revolution, and downward movement of the spindle during the arresting action is avoided. The upper end of a spindle 1, Fig. 1, has staked to it a housing 2 having two outstanding lugs 3 serving as bearing points for a pawl 4 in the form of an oval cage 9 having two upstanding arms 10A, 10B, Fig. 2, asymmetrically shaped so that in the equilibrium position of the pawl 4 the ends of the arms lie on opposite sides of a plane containing the pivotal axis of the pawl and the axis of the spindle (see Fig. 3). A pin 8 projecting downwards from a fixed member 7 lies in the path of rounded inwardly-facing lugs 11, Fig. 3, at the tops of the arms 10A, 10B. In operation, when the spindle rotates in the direction of the arrow, Fig. 2, (the forward direction) the lug 11 on the leading arm 10A abuts the pin 8, and as a result the pawl is rocked into the limiting position shown by the chaindashed lines, where the radiused face 12 of lug 11 (see Fig. 3) clears the pin 8. The pawl is thus freed, and rotation continues, the pawl being successively pivoted from one limiting position to the other. If the spindle rotates in the opposite direction, however, the configuration of the parts is such that the lug 11 cannot clear the pin 8, so the rotation is arrested.

Abstract: 1,264,678. Conveyer systems. AMERICAN CHAIN & CABLE CO. Inc. 9 May, 1969 [13 May, 1968], No. 23653/69. Heading B7L. In a tow truck conveyer system, fixed projection 71 and extension 72 are provided, so that rear truck bumper 34 only comes into play when the truck 10c is near the junction of a branch track 15, in which case bumper 34 either yields idly to the pressure of a front bumper 26 of a truck 10b or, if it is locked in the rearward position, it resists the pressure of such a bumper and stops the truck 10b. When the trucks are in the same straight line, bumper 26 is operated by projection 71 and is thus moved rearwardly whether or not tow pin 11 is lowered. The rearward motion of bumper 26 raises pin 11 by the co-operation of parts 30-32, applies conventional brake 52, locks bumper 34 in the rearward position by roller 41 engaging the top of cam 39 and compresses a return spring. A retaining pawl 66, controlled by a bumper 61, engages a fixed rack 67 to prevent a premature return of bumper 26. An additional sprung and damped bumper 43 is provided for pushing truck 10c along track 15.

Abstract: 1308152 Pyridines IMPERIAL CHEMICAL INDUSTRIES Ltd 6 July 1970 [7 July 1969] 34180/69 Heading C2C Pyridine or an alkyl pyridine is produced by contacting a piperidine which has two alkyl groups substituted on the same carbon atom with a hydrogenation catalyst in the presence of hydrogen. The preferred alkyl groups are methyl and ethyl. The reaction is preferably carried out at a temperature in the range 300- 1000‹ C. At lower temperatures in this range the production of alkyl pyridines is favoured and at higher temperature pyridine production is favoured. Suitable catalysts are, for example, ruthenium, iridium, palladium, osmium, rhoddium, platinum, copper chromite or nickel. Platinum and palladium catalysts are suitably supported, e.g. on alumina or charcoal. An example is given of the conversion of 3,3-dimethylpiperidine to mainly 3-methyl pyridine with some pyridine and lutidines.
