Abstract: 613,426. Expanding-wheel gearing. KUNER, W. H., and BERGER, A. F. June 28, 1945, No. 16543. Convention date, Feb. 5, 1944. [Class 80 (ii)] In expanding-wheel gearing having driving and driven members, each with co-acting fixed and movable coned flanges, the movable driving and driven flanges are interconnected by an integral mounting slidable in stationary guides on which the other flanges are mounted. Preferably, the mounting is actuated by means acting in the plane of the cone axes. As shown, the gear comprises two pairs of co-operating coned members 4, 5 and 9, 10, Fig. 2, splined to but not journalled on the driving and driven shafts 1, 6 respectively, and drivingly interconnected by a rigid friction ring 11. The cones 4, 10 of each pair are normally axially fixed and are journalled in housings 17, 20, each having axially projecting offset pairs of arms 18, 21 respectively, Figs. 8 and 10, which are superposed and both clamped to a casing member 24, Fig. 11, and which locate and guide a slidable member 12, carrying the housings 14, 15, Figs. 9 and 2, in which the movable cones 5, 9 are journalled. The member 12 carries a screwed extension 47 on which is mounted an axially fixed worm-wheel 49 which can be turned through a worm 50 actuated by a graduated hand-wheel (not shown} to vary the gear ratio. A worm drive 53, 54 from the cone 10 for a tachometer is also provided. Individual initial axial adjustment of the cones 5, 10 in their housings is provided by screwed backing rings 59 locked by set screws 60. Lubrication for the whole system is supplied by a gear pump 34, Fig. 11, which is actuated by a worm drive 36, 35 from the cone 4 and which draws oil from a sump 29 through a valve block 40 and delivers it through a passage 42 to interconnected oil duets defined by mating axial grooves 43, 43<1>, Figs. 8 and 9, 10, in the co-acting surfaces of the members 12 and 18, 21 respectively, and which lubricate through subsidiary ducts 45-45<111> and 46 the ring, cones and cone bearings. The oil is returned to the sump 29 by gravity from a drain pan 25 along an inclined peripheral passage 26 and is cooled by air blown beneath the raised base 271 of the casing 23 by a fan 28 on the shaft 1.

Title: Improvements in or relating to the manufacture of molecularly oriented thermoplastic films
Inventor: WATSON MAXWELL HARRY ERNEST
IPC: B29C59/00
Filed: 1964-04-21
Abstract: 1,100,594. Heat-setting films. BRITISH CELLOPHANE Ltd. 13 April, 1965 [21 April, 1964], No. 16556/64. Heading B5B. A travelling film of a polymeric thermoplastic material which has been stretched and oriented in the transverse and/or longitudinal directions is heat-set by passing it through a heating zone where it is flash-heated to a temperature between the temperature at which it was stretched and the melting point or softening point of the film material and restraining the film from shrinkage by cooling the film in intimate contact with the chilled peripheral surface of a rotating drum to reduce the film to a temperature at which the film on removal from the surface shows substantially no tendency to shrink, the film being caused to travel through the heating zone at a speed not less than the peripheral speed of the drum. The flash-heating of the film may be effected by radiant heat and the heating zone may extend beyond the line of initial contact between the film and the surface of the drum. The film may be supported on the peripheral surface of a rotating roller while passing through the zone in which it is flash-heated by radiant heat. The flash-heating of the film may be effected by passage over a rotating heated drum with the peripheral surface of which it makes intimate contact. When the film has been previously stretched in the longitudinal direction its degree of shrinkage in that direction during the heat-setting may be controlled by controlling the rate of passage of the film through the heating zone. When the film has previously been stretched in the transverse direction the degree of shrinkage in that direction is controlled by the speed of delivery of the heated film to the peripheral surface of the cooling drum. The cooling drum may be cooled by passing a cooling liquid through it. When the flashheating is effected by means of a radiant heater the position of the latter may be adjusted in a path parallel with the path of travel of the film to the cooling drum. When the flash-heating is effected by means of a drum, the latter is heated internally by electric heaters.

Sights and methods of sighting.- Consists in logarithmic apparatus for determining the future position of a moving target from its known present position and rates of angular movement in latitude and azimuth. More specifically the invention comprises logarithmic apparatus designed to solve the equations (1) log cot S2 = log cot S, + log (1 + et sec S, cosec S1) + log sec D, and (2) #bt# tan # D = 1 Œ et sec S<1> cosec S<1> where S1 is the present angle of sight, S2 the future angle of sight at the end of a time t, D the change in azimuth in the time t, and e and b are the rates of angular movement of the target in altitude and azimuth respectively at the beginning of the time t. The target is assumed to be moving at constant speed in an horizontal straight line. The apparatus shown comprises a drum connected by a double differential gear B to shafts C, D, and E adapted to be set in accordance with the right hand terms of equation 1, so that the drum A receives an angular movement proportional to log cot S2. The surface of the drum A is marked with curves connecting quadrant or tangent elevation and height in such a way that the pointer S, when set to a particular height curve, indicates on a scale T the quadrant or tangent elevation. Electric apparatus U is provided for transmitting the angle of quadrant elevation to the gun. A part of the drum may be marked with fuze time curves which are read against a pcinter h. The second equation is solved by the left-hand part of the apparatus comprising the drum L and the pointer b. The drum L is mounted on the shaft D and receives a rotation proportionate to log (1 + et sec S, cosec S1). The drum is marked with curves of b.t. so plotted that when the pointer b is set to a particular value b.t by means of the, screw c, it receives a movement proportional to D. Means are provided for making wind and spotting corrections. For the wind correction, the screws k and c by which the pointers S and b are moved, receive endlong movement by means of levers d, c<x> connected to cross-heads e, f operated by a crank pin g which rotates equiangularly with the gun in training. The crank pin is adjusted initially in accordance with the strength and direction of the wind. For effecting spotting corrections the pointers may receive independent adjustment.

Title: Coherent pulse doppler altimeter
IPC: G01S13/88
Filed: 1971-05-25
Abstract: 1330917 Radio altimeter HOFFMAN ELECTRONICS CORP 25 May 1971 [3 Feb 1971] 16898/71 Heading H4D Pulsed radio altimeter transmits a constant high duty cycle variable P.R.F. train of pulses, Fig. 2, the P.R.F. being automatically varied until the leading edge of the ground return occurs mid-way between two consecutive transmitted pulses, the P.R.F. then being a measurement of the altitude. Doppler frequency shift is detected in the returns and narrow band filters only pass Doppler shifted components of the first order side-band such that echoes from fixed objects, e.g. aircraft wheels, or bombs, are rejected. The use of narrow, noise rejecting, gating in the tracking of the ground return leading edge and the high permitted duty cycle allows the peak power of the transmitted pulses to be very low. R.F. oscillator 10, Fig. 1, transmits coherent pulses of radiation at 4À3 GHz. via isolator 20 and switch 12, the latter being controlled by oscillator 14 to give the constant duty cycle gating pulses. Noise, echoes at 4À3 GHz. from fixed objects and Doppler shifted echoes from the ground are passed by bandpass filter 16 (4À2-4À4 GHz.). A wide range gate pulse, having a trailing edge coincident with midway between transmitted pulses, is generated by variable frequency voltage controlled oscillator, and applied to range gate switch 22 comprising P.I.N. diodes. Doppler frequencies are extracted by a balanced coherent mixer 26 using part of the output of oscillator 10. The Doppler frequencies are separated from noise by a narrow gate NGR applied to I.F. amplifier 32 and timed at the trailing edge of the wide range gate to give the output of the bottom line, Fig. 2. The Doppler shift of the first order side-band is extracted by mixing at 34 with the pulse repetition frequency from oscillator 14. The final Doppler output is detected at 38 and passed to a threshold switch actuator 40. During the search mode, the pulse repetition frequency of oscillator 14 sweeps from 50Hz. to 25 MHz. When an echo with the necessary Doppler shift is acquired, the threshold of actuator 40 is exceeded and switch 42 moves to the upper or track position in with the detector output, after filtering and integrating, is applied to control the oscillator 14. The pulse repetition frequency is extracted from oscillator 14 and processed at 50 and 52 for various uses and height indications. The constant duty cycle principle is abandoned at very low, e.g. 10 feet, attitudes, the pulse width being kept constant while the P.R.F. varies.
