Abstract: 535,295. Quenching articles. BRAYSHAW FURNACES & TOOLS, Ltd., BRAYSHAW, S. N., and RUSHTON, F. Sept. 26, 1939, No. 26648. [Class 72] In a device for quenching metal articles in a tank A containing liquid, the heated articles are placed in an openwork receptacle D<SP>4</SP> secured in clips d<SP>3</SP> in a cradle D which is supported in a catch pot or receptacle C on arm d keyed to a shaft E mounted in bearings and extending across the tank A. A cover F for the tank A is in the shape of a right-angled sector formed of two plates f connected by a curved plate f<SP>1</SP> and is pivoted on the shaft E at the corner of each plate f. A second cover G of the same shape as the cover F is fixed to sleeve g loosely mounted on the shaft E and is rotated with the latter, when the handle H is turned, by the engagement with a slot in an arm g', Fig. 2, of a roller g<SP>5</SP> mounted between arms g<SP>4</SP> on a sleeve g<SP>3</SP> on a stub shaft g<SP>2</SP> carrying a gear g' which gears with a wheel h<SP>3</SP> of a reduction gear train h<SP>1</SP>h<SP>2</SP>h<SP>3</SP>h<SP>4</SP>, the latter being fixed on the shaft E. A counterweight D<SP>1</SP> for the cradle D is mounted on the shaft E, and the weight G' for the cover G on one of the sleeves g. When it is desired to deposit the heated articles in the receptacle D<SP>4</SP> with the basket B placed in the tank A, the handle H is rotated to turn the receptacle into a position over the basket B and at the same time by means of the gearing h<SP>1</SP>, &c.. the roller g<SP>4</SP> is caused to leave the slot in the arm g<SP>7</SP> and thus turn the cover G over the not A. The cover F is provided with handles f<SP>3</SP> so that it may be raised slightly to allow of the removal of the quenched articles from the basket B. Instead of the latter a conveper belt may be provided in the tank A and moving over the edge of the latter. The angular movement of the cover G is faster than that of the cradle D so that the pot A is covered before the cradle D discharges its articles into the tank.

Abstract: 1,184,058. Wave-energy position finding. PLESSEY CO. Ltd. 14 June, 1967 [16 June, 1966], No. 26857/66. Heading H4D. A ranging system comprises radiant energy detecting means affording an energy gradient measurement with respect to the time or distance range from the energy source and means for comparing that gradient with a signal forming or derived from the signal from which the gradient was obtained. Any form of wave energy may be employed, sound waves being utilized in the embodiments. Distance ranging, Fig. 1.-It is shown that if the sound pressure at microphones M 1 , M 2  is P 1 , P 2  respectively, the distance r conforms to the equation: P 1 /r = (P 1 -P 2 )/l where l is the spacing, along the wave path, of the microphones. Thus, if wiper 8 is set up according to spacing l, the position of wiper 9 when the corresponding outputs are equal gives distance r. The microphones are positioned along the wave path by a direction finder, Fig. 2 (not shown). Separation time t between a moving source and a microphone utilizes the fact that t=P/(-dP/dt), Fig. 3 (not shown). Examples of application of the invention are: traffic control, marine vessel ranging, isotope tracing, aircraft approach, and obstruction approach time determination on rail and road vehicles.

Title: Arrangement for distortionless pulse phase modulation
IPC: H03K9/04
Filed: 1948-10-18
Abstract: 652,333. Pulse modulation circuits. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. Oct. 18, 1948, No. 27036. Convention date, Oct. 17, 1947. [Class 40 (v)] Relates to an arrangement wherein phasemodulated pulses are produced by superposing a sinusoidal voltage and a modulating voltage and generating a short pulse at the instants the composite voltage passes through zero. The modulating voltage consists of amplitudemodulated rectangular pulses, the amplitudes of which are proportional to the value of the modulation signal at equidistant instants of time and whose leading edges have a phase lead of at least 45 degrees with reference to every second zero value of the sinusoidal voltage. In the circuit described a control generator 1, Fig. 3, supplies the sinusoidal voltage e<SP>1</SP>, Fig. 4 (a). After phase-displacement of about 90 degrees in circuit 2, 2a to give voltage e<SP>2</SP>, Fig. 4 (b), the wave is converted by limiter valve 3 to the trapezoidal form i 3 , Fig. 4 (c), and differentiated in circuit 4, 5 to give pulses e 4 , Fig. 4 (d). The positive pulse of each pair renders valve 6 conducting and the amplitude of the output pulses i 6 <SP>1</SP>, i 6 <SP>11</SP>, Fig. 4 (e), is determined by the amplitude of the modulating signal e m  applied to a second control grid of the valve 6. The output pulse is lengthened by condenser 8 which charges through diode 9 and is later discharged by triode 10 to the grid of which voltage wave eg 10  is applied from generator 1. The resulting lengthened pulses e sb , Fig. 4 (e, f ), are applied to valve 11 and mixed with a sinusoidal wave e 1 <SP>1</SP>, Fig. 4 (g), derived through valve 11a from the generator 1. The composite wave is fed to the limiter valve 13. to produce the trapezoidal wave i 13 , Fig. 4 (h), which is differentiated by circuit 14, 15 to give pulses i 17 , Fig. 4 (i). The positive phase-modulated pulses of each pair are passed on by valve 17 to the output circuit. A number of such modulators may be controlled by different phases of the master generator to provide channel pulses for an interlaced multiplex system, Fig. 1 (not shown).

Filed: 1919-11-12
Abstract: 150,919. Atkins, H. F. Nov. 12, 1919. Turning.-An apron mechanism for lathes having automatic surfacing and traversing feeds has means to prevent the two feeds from being engaged simultaneously and to disengage the saddle in case of obstruction. The worm sleeve b, splined on the shaft a, is moved by means of a pinion r and circular rack h to one of three positions and retained by a spring-pressed stop q. When the latter is located in the groove g the worm c drives the surfacing-screw through the wheel k and pinion l. When the stop is moved to the groove e, the traversing-worm d engages the wheel m, which is solid with a pinion engaging a wheel operating the traversing-feed. The mechanism may be actuated by hand when the sleeve b is in the central position. As soon as the automatic feed is checked, the worm screws out of mesh until the stop regains the central groove f.
