Title: Irradiation of solid bodies
IPC: B23K15/00
Filed: 1963-02-26
Abstract: A method of forming apertures in a solid mica body, preferably in sheet form, comprises subjecting the body to a source of heavy energetic charged particles and thereby producing particle "tracks" within the body, and then etching with hydrofluoric acid from the body at least a portion of the material defining said "tracks." Preferably each of the said tracks is straight, and the cross-sectional area thereof is substantially constant over its length, and said cross-sectional area of each of said tracks is substantially equal to one another.  The body may be irradiated through a mask or shield such that the resulting tracks are disposed with their longitudinal axes substantially parallel. The source of radiation may be oxygen ions, alpha particles or U-235 uranium which is preferably produced by irradiating a uranium sheet with a neutron source.  After etching the body may be rinsed.  The body may be further etched with a second etchant, e.g. caustic soda, which attacks the material in a direction perpendicular to the layer planes thereof.  The invention also comprises a mica body suitable for use as a molecular sieve which is a sheet of mica having a plurality of rectilinear apertures extending therethrough, said apertures being of cross-sectional dimension between 5 and 20,000 Angstroms.  The axes of said apertures are preferably parallel and the apertures may be filled with a filler to form rod-like deposits in said body.

Filed: 1973-02-16
Abstract: 1399774 Externally-meshing gear pumps and motors SPERRY RAND CORP 16 Feb 1973 [17 Feb 1972] 7625/73 Heading F1F [Also in Division F2] An externally meshing gear pump or motor comprises plain bearings 24 for shafts 16, bearings 24 being constructed as cantilevers attached only at their outer ends to body 10 so that the bearings deflect under high fluid pressure to substantially the same degree as shafts 16. The outlet and inlet ports extend at both sides of the gears so as to have parts thereof directly communicating with the bearings. The load/deflection ratio of the bearings is accordingly made greater than that of shafts 16 since the area of the bearings exposed to outlet pressure produces greater forces on the bearings than those acting on shafts 16 due to pressure at the meshing zone of the gears.

Title: Apparatus for investigating torsional oscillations or cyclic speed variations in rotary members
Inventor: CLARKE MICHAEL EDWARD
IPC: G01H1/10
Filed: 1952-03-25
Abstract: 711,185. Torsiographs. NAPIER & SON, Ltd., D. March 17, 1953 [March 25, 1952], No. 7680/52. Class 40 (1). Torsional oscillations in a rotating shaft A' are measured by attaching thereto a phonic wheel A, the pick-up B of which produces a carrier current frequency modulated by the cyclic variations in shaft speed. This output is fed through a constant output amplifier D, a frequency discriminating network E, integrator F, and amplifier G to a cathode ray tube indicator H. The integrator is provided to compensate for errors introduced by the discriminator so that the indication is correct for both amplitude and frequency. The C.R.T. timebase is triggered by impulses produced once per cycle of operations which may be one or more revolutions, by the passage of a single rotating pole on or geared to the shaft past a pick-up C. Amplitude modulation of the carrier frequency is avoided by having the pick-up B designed to give an output independent of rotor speed, and by having 3 series connected pickups B spaced roughly 120 degrees apart around the rotating member and arranged to give in phase 'outputs so that. radial vibration of the shaft produces no change of amplitude in the resultant output.

The inlet is regulated by an adjustable concentric hollow cylinder in the inlet cylinder having a registering opening. A helical directing-vane is fixed in the inlet. The rotor m is of truncated conical form, but may be cylindrical, and carries helical vanes n and also a perforated disk o to which it is adjustably connected by spring-pressed pins q entering pairs of several recesses u in the rotor. To adjust the size of the outlet openings of the rotor when the turbine is stopped, the disk o is rotated by depressing a shaft u<1> against the action of a spring x to cause a pinion v to engage with teeth o<1> on the rim of the disk o. Rotation of a hand-wheel v<2> causes rotation of the perforated disk o relativelv to the rotor, and thus varies the size of the outlet openings of the rotor. A hollow cylindrical portion e with an opening e<1> registering with the inlet b is rotated to regulate the size of the inlet by operating a hand-wheel f<2> to actuate a pinion f meshing with internal teeth on the hollow cylinder e. A helical guide vane h fixed in the inlet may be fixed to the hollow cylinder e, or may be formed integral with it.

The die 2 comprises an outer frame 7, which co-operates with the die 1 to form a closed chamber, and an inner piston-like member 9 adapted to define a variable cavity within the mould and forming the mould core. Moulding composition is introduced before or after the mould is closed ; if it is introduced after the mould is closed it is injected through an aperture provided in one or both dies. The mould being closed, piston 9 is raised (Fig. 3) to compress and distribute the material, normally under heat. Die 1 is carried by a platform 3 fixed on pillars 4. Die 2 is carried by a platform 5 which slides on pillars 4 under the influence of hydraulically-operated rams 6. The ram 10 which moves the member 9 also is hydraulically-operated. The moulding composition may be introduced into the mould in the solid state, or may be incorporated in the reinforcement while the latter is being preformed to the desired shape. The composition may be applied mainly only to that side which will be the outer side of the finished article. The reinforcement may be treated with a material which will promote adhesion of the composition thereto.

Filed: 1939-03-14
Abstract: 527,768. Correspondence control. BRITISH THOMSON-HOUSTON CO., Ltd. March 14, 1939, No. 8208. Convention date, March 14, 1938. [Class 40 (i)] In a rudder-control system of the type in which the transmitter and receiver are similar machines, having interconnected 3-phase rotors, the transmitter stator being fed with singlephase current and currents induced in the receiver stator being used, with the help of a Ward-Leonard system to control the position of the rudder and the re-positioning of the receiver rotor into correspondence with that of the transmitter, these currents directly excite the Ward-Leonard generator via a rectifier bridge 29 which is also excited with A.C. in the same phase as that which feeds the transmitter stator. The Ward-Leonard generator may have an additional self-energized field winding 282 and the rudder may be driven by a servo-motor (not shown). A rudderposition indicator 14 may be connected as shown but is preferably controlled by a separate transmitter driven by the rudder. Preferably the controlling handwheel 13 drives the transmitter through elliptical or other non- uniform gearing so that a given angular displacement of the wheel produces a smaller movement when the rudder is central than when it is deflected. The full range is given by a single turn of the wheel and this enables sliprings to be dispensed with in the machines. In a modification, Fig. 2 (not shown), the rectifier 29 is replaced by a pair of bridge rectifiers which are connected in parallel and in opposite directions to the supply and coupled to the receiver-stator and the Ward-Leonard generator by a centre-tapped transformer so as to make use of both half-cycles of the control current. In a further modification the centre-tapped transformer is omitted and the Ward-Leonard generator has a tapped field-winding the halves of which are effective in turn.
