Title: A q switching and mode locking gas laser arrangement
Inventor: KRUPKE WILLIAM FRANKLIN
IPC: H01S3/098
Filed: 1970-01-12
Abstract: 1300107 Lasers HUGHES AIRCRAFT CO 12 Jan 1970 [10 Jan 1969] 1343/70 Heading H1C A laser resonant cavity contains a cell 15 within which there is a mixture of a repetitively bleachable gas and an absorbing gas having a transmission band at the required laser output frequency, the former gas acting as a passive Q switch and the latter as a suppressor of undesired output frequencies. Suitable bleachable gases for use at the output frequencies of a CO 2  or N 2 O laser are C 2 F 3 Cl, CF 3 CCl 3  or CH 3 CF 2 Cl, while the absorbing gas may be SF 6 , BCl 3 , CH 3 CF 2 H, CH 2 CF 2  or C 2 F 3 Cl. In Fig. 1, the gases for cell 15 are supplied from storage cylinders 24, 25 via valves 19, 22 and 23. The resonator comprises a spherical gold plated mirror 13 and a ZnS coated barium fluoride plane mirror 14. With a 20 : 1 ratio of absorbing ; bleachable gas and a total pressure of 4 Torr., a pulse repetition frequency of 20 kHz occurs for a CO 2  laser with an output wavelength of 10À6 Á. The bleachable gas also produces mode locking.

Title: Improved variable speed gearing
IPC: F16D31/06
Filed: 1935-01-15
Abstract: 450,360. Hydro mechanical variable-speed gearing. WOOLER, J., The Willow Bungalow, West End Lane, Ruislip, Middlesex. Jan. 15, 1935, No. 1353. [Class 80 (ii)] Bevel planet - pinions 11 carried by a driving casing 1 and engaging a driven bevelwheel 14, are restrained from rotation about their own axes, by the gyroscopic action of hollow rotors 9, secured to the planet-pinions, and filled with fluid to a variable extent under the control of manuallyadjustable valves 25, which allow the fluid to escape centrifugally from the rotors and casing. The rotors 9 thus constitute fly-wheels of controllable mass, and their restraining influence may be increased by vanes 29b. Fluid is fed into the rotors at 31 and escapes through ports 9e in their crowns, a common annular duct 24b in the casing 1, ports 25d in the valves 25, the hollow interior of the latter, and peripheral casing-ports 28 into an outer fixed casing which houses the gear. The valves 25 are axially adjusted to vary the flow, by a common sliding collar 15, operated manually by a rack-and-pinion 21, 22.

Abstract: 1,217,541. Moulding dough. C. W. VOGT. 10 Jan., 1968, No. 1404/68. Heading B5A. [Also in Division B8] Each pocket of a pocket wheel feeder is provided with a gas-permeable liner, the space between the pocket wall and the liner being connected through radial passages 32 to a suction source or to a pressure source at the receiving and discharge positions respectively. The pocket wheel is rotatable around a stator 23 which is formed with recesses 34, 35, connected through ports to the suction and pressure sources respectively, and with radial passages 44, 45 leading to atmosphere through an axial passage 42.  Material, which may be particulate material or material such as dough, enters the pocket liners from a hopper 46 and is retained therein by suction applied through the radial passages 32 and the recess 34. As the pocket wheel rotates the pockets are vented to atmosphere through the passage 44 and are then connected to the pressure source through the recess 35 to assist the discharge of material from the pockets through the discharge opening at the base of the feeder housing 11. The empty pockets are then vented to atmosphere through the passage 45 to release any excess pressure in the pockets before being connected again to the suction source at the receiving position. The pocket liners are formed from woven cloth sandwiched between wire mesh material, Fig. 3 (not shown). For use with material such as dough a driven trimmer roller 82 may be provided to cause uniform filling of the pockets.
