Title: Improvements in or relating to the guiding of wave beams
IPC: H01P3/20
Filed: 1962-04-11
Abstract: 1,006,409. Light beam communication systems. BEAM GUIDING Inc. April 11, 1962 [April 11, 1961], No.13974/62. Heading G1A. [Also in Divisions G2, H1, and H4] An electromagnetic wave transmission system for use in the sub-millimetric, infrared, and optical ranges, comprises means for producing a freespace wave beam having a substantially planar wave front and an iterative structure consisting of a number of irises each operative upon the circumference of the beam to diffract the beam and re-set the phase and amplitude distribution of the beam cross-section. The structure consists essentially of irises 17, Fig. 2, which may be arranged within a tubo 18. Each iris re-sets the phase and amplitude distribution at the next succeeding iris to what it was at the immediately preceding iris. The beam is derived from a high intensity light source 11 which is associated with an iris 12 having an aperture such that the beam is sufficiently coherent for guided transmission through the system. The beam is modulated by means of a Kerr cell 23 arranged between a polarizor 24 and an analysor 25. The modulated beam is passed through the iris transmission system which consists of irises 17 having a radius R and a spacing D related to the wavelength # by the equation a = #2n/#D. R where a ~ 100 or less. The beam is detected by a photo-electric cell 19. In the system of Fig. 3 a coherent source 27 such as a laser is used. By means of a lens system 28, 29, 30, the image of the plane 33 is enlarged to the size of the aperture of the transmission system 31. Specification 923,202 is referred to.

The retort is supported at the inlet end by rollers 19 and at the discharge end by a drive shaft 23 in a bearing 24 with drive mechanism 26. Baffles 52, 54 assist in defining the hot gas recirculatory path and excess gas is removed by a flap controlled flue 60. Thermostats 56 and 58 near the fan outlets 46b and the intakes 46a control the temperature of the work within narrow limits, e.g.  10 F. The inlet shoot 21 is fed through holes 30 and is controlled by a flap valve 21a. A discharge hopper 36 fed by shoot 34 has a flap valve controlled by a motor 40 and also has an extension shoot 42. A frusto-conical baffle 32 prevents incoming work falling through the holes 28.

Title: Improvements in Variable Velocity Ratio Transmission Gear.
Inventor: LEWIS ALFRED
IPC: F16H61/662
Filed: 1918-09-02
Abstract: 122,374. Lewis, A. Sept. 2, 1918. Variable-speed epicyclic gearing.- In a variable-speed gear, one member of an epicyclic train is controlled by another epicyclic train through disk and roller friction gearing, the disks of which revolve with the driven shaft, the parts being so arranged that the gearing rotates as a whole at the top speed. Compound pinions 28 mounted in a planet carrier 30 keyed to the driven shaft 31 engage two sun wheels, one 27 keyed to an intermediate shaft 2, and the other 26 driven at variable speed by a roller 23 engaging two disks 45 rotated by bevel gearing 49 from the shaft 2. The disks 45 are mounted in bearings in two levers 32 pivoted to the planet carrier 30 and connected by links 33, 35 to a movable collar 34, by means of which they may be withdrawn from contact with the roller 23. Weights 38 on the links 35 balance the effect of centrifugal force on the levers 32. The driving-shaft 1 is connected to the shaft 2 by a torsion-spring coupling 3, and keyed to the shaft 1 is a cam 7, Fig. 5, which acts on rollers 8 to move a casing 9 to the light, the extent of movement being limited by stops 52. Collars 15, 19 on the casing 9 and roller 23 are connected by rods moving against springs 17 so that the position of the roller 23, and consequently the speed of the driven shaft 31, vary with the load. The roller 23 may also be operated manually, and by moving it to the edge of the disk 45 a reverse speed is obtained. Initial tension is put on the spring 3 by rotating the casing 9, which is then fixed by screws 13 to a collar 11. In a modification, two rollers sliding on the radial spindles 46 engage a disk fixed to the wheel 26, and the levers 32 are replaced by springs holding the rollers in gear.

Abstract: 222,081. Browning, J. M. Sept. 21, 1923, [Convention date]. Machine guns.-A device for regulating the rate of firing of automatic guns comprises retarding mechanism which, when the gun is fired, is moved into operative position whereby the trigger is locked in the unpulled position, the retarding mechanism then, on the movement of the firing mechanism following the discharge, releasing the trigger and slowing down the pulling movement. As shown, the delay mechanism comprises a lever 19 adapted first to depress the trigger 12 to ensure that the sear 14 shall be free to engage the cocking notch, and then to rise slowly under control of an escapement device, to delay the pulling movement of the trigger. The escapement device comprises a double pawl 18 engaging a notched wheel 17c keyed to a shaft 17 carrying a ratchet wheel 17b which is engaged by a depending rack 20 on the free end of the lever 19. The lever 19 is mounted above the trigger 12 so that it engages a shoulder 12d thereon and is depressed by the action-slide 2, when the gun is fired, as shown in Fig. 1. During the recoil, the lever is held depressed by a spring catch 21 which is released by a slight forward movement of the sear 14 when the slide 2 is cocked as shown in Fig. 3. The lever is then free to rise slowly under the control of the escapement device, and thus permits of a slow pulling movement of the trigger.

Filed: 1920-06-02
Abstract: 144,293. Western Electric Co., (Assignees of Clark, A. B.). Sept. 20, 1918, [Convention date]. Amplifying and repeating systems.-In signalling systems in which currents of different frequencies are used at different times (for example, in a telephone repeater system which amplifies voice-currents and must also be able to deal with ringing-current of lower frequency, such as 133 cycles per second) means are provided which respond to currents of a particular frequency (such as the ringing frequency) to improve the transmission of that frequency. In the repeating system shown in Fig. 1, ringing-current energizes a relay 11 in a tuned circuit bridged across a, condenser 12 on the out-put side of the amplifier 1, and the relay 11 de-energizes a relay 10 to bridge a condenser 7 across the input transformer 2, forming a circuit resonant to currents of the ringing-frequency, whereby the amplification of such currents is greatly increased. The relay 10 also open-circuits a potentiometer 6, which is normally bridged across the input circuit and which serves to adjust the degree of amplification of voice-currents.
