Title: Attitude control system for sounding rockets
Inventor: ROBBINS HOWARD JAY
Filed: 1964-09-22
Abstract: 1,075,705. Controlling spacecraft. AEROJETGENERAL CORPORATION. Sept. 22, 1964, No. 38612/64. Heading B7G. A ballistic vehicle has two gyroscopes providing roll, pitch and yaw reference attitudes, jet nozzles for rotating the vehicle about roll, pitch and yaw axes to reduce the vehicle attitude error, and a timer for sequentially varying the reference attitudes by applying torques to the gyros to cause the vehicle to be orientated in a succession of attitudes. The vehicle described is a sounding rocket in which the succession of attitudes is used for observations. Control construction.-The rocket body has two pairs of tangentially arranged roll control nozzles (21a, 21b and 22a, 22b) in an attitude control section (20, Figs. 1 and 2, not shown) and one pair each of yaw and pitch control nozzles in the tail of the rocket. The gas supply for the nozzles is taken from pressurization tanks for the launch propellant, and is controlled by solenoid valves. The two gyroscopes (35, 36) have outer gimbals (35b, 36b) rotatable about axes parallel to the roll axis, and inner gimbals (35e, 36e) rotatable about pitch and yaw axes. The attitude control section also contains a programmer 40 comprising a series of rotary switches (40a) driven by a stepper motor (51) controlled by a timer (50). Pitch, roll and yaw rate gyros are also provided, and torque motors T and synchros S respectively apply torque to the gyros (35, 36) to change their reference attitudes and direct changes in the attitudes. Control programme.-The rocket is spinstabilized during its ascent and this spin is taken off when the programmer is actuated (by a switch (45) sensitive to the acceleration change on burn-out) by operation of a solenoid valve (60) under the control of the roll rate gyro (63). In the next stage, the attitudes of the gyros (35, 36) are changed by a programme corrector set up immediately prior to launch to correct, e.g. for launch tower tilt. Roll, pitch and yaw correction signals are supplied by leads (46, 44, 45) to torque motors (35d, 35c and 36c) and the resultant precession of the gyros produces correcting torques from the control nozzles until the resultant outputs of the roll rate gyro (63) and synchro (35f), the pitch rate gyro and synchro (35g), and the yaw rate gyro and synchro (36g), are washed out. The synchro (36c) and torque motor (36d) form a servo loop by which the gyro (36) is precessed to keep the axis of the inner gimbal parallel with the rocket yaw axis. In subsequent stages in the programme controlled by the timer (50) appropriately valued resistors (40b) are inserted in sequence in the lines (46, 44, 45) to the roll, pitch and yaw torque motors (35d, 35c and 35f) respectively to rotate the rocket to a desired orientation, which is held for a predetermined time before the rocket is re-orientated.

Abstract: Alkyl aluminium containing only small amounts of the iso-butyl radical are prepared by reacting an olefin CH2 = CR1R2 where R1 and R2 are aliphatic, alicyclic, aromatic or hydrogen and the total number of carbon atoms is 3-20, with an alkyl aluminium of formula Al(i-Bu)3-m-nRmHn where R = -CH2CR1R2H, m = 2, 1 or 0, n = 1 or 0 and m + n is not greater than 2; a gas inert to the reactants (e.g. orgon, nitrogen, hydrogen, ethane, propropane or butane) being bubbled through the solution.  An excess of the olefin is mixed with the alkyl aluminium in an inert solvent if required, an inert gas bubbled through at a rate between 0.005 and 0.5 moles per minute per mole of aluminium and the mixture heated to between 90 DEG  and 180 DEG  C., the apparatus being pressurized, if necessary. Isobutylene is evolved and the alkyl aluminium left, together with excess olefin from which it is separated.  The reaction may be carried out in a solvent which is preferably a hydrocarbon inert to the reactants.

Abstract: 1388934 Xerographic member XEROX CORP 24 Aug 1972 [2 Sept 1971] 39536/72 Heading G2C A xerographic member capable of storing a developable image comprises a conducting substrate 11, an insulating barrier layer 12, a photo-receptor layer 13 comprising vitreous selenium or selenium-arsenic alloy doped with thallium, and photo-conductive layer 14. Substrate 11 may be brass, aluminium, steel metallized paper, plastic coated with aluminium, glass coated with chromium or tin oxide and may be a sheet, web or cylinder. Barrier layer 12 may be epoxy or polycarbonate resin, or an aluminium oxide coating formed by anodizing an aluminium cylinder.

The device is then negatively charged Fig.3 (not shown) and exposed to imaging radiation Fig.4 (not shown) generating further electron-hole pairs in layer 14 and resulting in recombination of electrons and holes at the trap sites in areas exposed to illumination. The remaining negative charge is removed using a conductive rubber roller and a latent image remains on layer 13 Fig.5 (not shown). The potential of the charge trapped may be varied by applying very high fields across the storage layer.

Class 98(2) [Also in Group XL(b)] In step-printing apparatus one master negative remains fixed in the exposure position and others are carried on a movable band and brought in turn into superposition with the fixed master during exposure. As shown, the printing and developing apparatus of Specification 812,909 is modified by adding a transparent flexible band 10 carrying the other master negatives either printed thereon or attached thereto and movable at right angles to the direction of feed of the photo-sensitive material. Band 10 is wound between rollers 11 and 12 by electric motor 17 and worm and wormwheel 20. The band is kept taut by torsion spring coupling 16. After each exposure a rising platen momentarily opens a switch which engages clutch 18 and releases brake 19 so that continuously running motor 17 feeds the band 10 until an opaque mark comes between lamp 26 and photo-cell 28 to operate a cold cathode relay and so apply the brake and disengage the clutch (see Group XL(b)). Limit switches 23, 24 are adjustably positioned with respect to nut 22 and, when operated by the nut, energize relays 33, 34 to reverse the current in the armature 17a of motor 17.

Patent GB-1078754-A (GB)
Title: Improvements in and relating to porous metal bodies
IPC: H01J1/28
Filed: 1964-10-01
Abstract: An emissive member of a thermionic ion source or of a thermionic cathode consists of a porous metal body the major portion of which has large pores which prevent distortion at operating temperature, and an emissive surface portion formed by a thin layer of fine porosity with a pore density between 1 million and 10 million per sq. cm.  In an example tungsten powder particle size 1 to 6 microns is compacted and sintered at 2100 DEG C. in a neutral or reducing atmosphere to form a sintered body with grains of 3 to 20 microns and a pore size of 1 to 12 microns.  The sintered tungsten may be impregnated with copper to aid machining, the copper then being evaporated.  A fine pored emissive layer of tungsten is then applied to the sintered body as a suspension of tungsten particle size 0.5 to 1 microns in amyl acetate and collodion.  Sintering in hydrogen at 1800 DEG C. produces a fine porous layer of 20 micron thick, particle size 0.5 to 6 microns and pore size 1 to 3 microns.  The surface of the sintered tungsten may be oxidized by heating in air at 500 DEG C. before applying the fine layer.  In an alternative method the fine layer may be formed by applying a suspension of tungsten trioxide which is reduced in situ during sintering.  The sintered tungsten coarse pored body may be impregnated with an alkaline earth metal compound prior to the application of the fine layer.
