Title: Nutation correction system for spin stabilized satellites
IPC: B64G1/38
Filed: 1969-10-16
Abstract: 1286087 Automatic attitude control POST OFFICE 16 Oct 1969 [18 Oct 1968] 50969/69 Heading G3R Nutation of a spin-stabilized satellite is detected by an accelerometer the output of which, when it exceeds a predetermined value, initiates reaction thruster pulses to reduce the nutation until the accelerometer output is reduced to a lower predetermined value. In Fig.1, a satellite 10 spins about an axis 12 and nutation is detected by offaxis accelerometers 14, 16, responsive to linear accelerations parallel to axis 12, which control, through a logic circuit 18, off-axis reaction jet thrusters 20, 22 to reduce the nutation. The logic circuit is such that thruster operation is not initiated until the accelerometer output reaches a predetermined high value. Thereafter the thrusters are operated for the periods during which the corresponding accelerometer outputs exceed predetermined lower values in either sense. As the nutation decreases in amplitude the periods of thruster operation become shorter but singleshot multi-vibrators ensure that the period of operation never falls below the minimum required for proper operation of the thrusters. When the time taken for the accelerometer output to vary from the lower predetermined value in one sense to the corresponding value in the opposite sense exceeds a predetermined time, indicating that these values are not greatly exceeded, thruster operation ceases and cannot re-start, unless the accelerometer output reaches the higher predetermined value again. Operation with a single accelerometer and thruster is referred to but pairs increase reliability. Commands transmitted from the ground may disable the automatic control and operate a thruster to change attitude. Commands transmitted from the ground may also vary the gain and timing of the automatic control to suit a changed rate of spin.

Title: Recording of data on a movable data carrier
IPC: G11B20/12
Filed: 1974-11-28
Abstract: 1484885 Data recording SIEMENS AG 28 Nov 1974 [20 Dec 1973] 51538/74 Heading G5R In an arrangement for recording data in blocks Bm, Bn spaced by intervals Lm &c. on a magnetic tape MB, the position for recording the next block of data is determined by driving the tape forwards until an interval S2-S4 longer than that Lm between blocks is detected then driving the tape in the reverse direction until the end S2 of the last recorded block Bn is detected and then driving the tape forward and stopping it after the tape has been moved to position S3 to provide the required interval Ln. The instruction to seek the recording position is a signal SL which via flip-flops F1 and F2 controls a motor circuit MS to move the tape in a forward direction. At the same time a timer T1, having a period longer than that required by the tape to move through interval LM, is triggered and is thereafter returned to zero time by any pulse signals derived from the detection of data blocks Bm &c. as these pass by head LK. When the timer times out it provides an output to switch flip-flop F2 which in turn applies a reverse direction signal to the motor circuit. The tape is driven in reverse until the head detects the end of the last recorded block to provide signals SS at the output of NAND gate N 4  which trigger flip-flop F2 to provide an output which in the motor circuit again drives the tape in the forward direction. The signals SS also trigger timer T2 designed such that when it times out the tape is stopped, by triggering flip-flop F1, at a position which is interval distance LN from the last recorded block.

Abstract: 1,030,218. Photographic processes using photochromic materials. NATIONAL CASH REGISTER CO. Dec. 21, 1964 [Feb. 4, 1964], No. 51793/64. Heading G2C. Silver images are produced by imagewise exposing a layer of one or more non-crystalline spiropyran compounds to ultra-violet, treating the imaged layer with hydrogen halide vapour until a yellow acid complex is formed (Specification 1, 030, 217), allowing the acid vapours to evaporate from the background areas, coating the layer with an aqueous solution of silver nitrate to form a silver halide image and then reducing this image to a silver image. The photochromic layer may be binder-free but preferably contains a cellulose ester or ether and is preferably coated on a glass or polyester support. After exposure, the layer may be treated with sulphur dioxide vapour before exposure to halide vapours, and after the formation of the silver halide image, the layer may be treated with ethyl alcohol to remove the unused silver nitrate. The silver halide is reduced to a silver image by using a photographic developer.

Title: Improvements in and relating to the preparation of wear-resistant structures
IPC: D21F1/52
Filed: 1967-11-15
Abstract: 1,200,904. Laminates. NORTON CO. 15 Nov., 1967 [15 Nov., 1966], No. 51926/67. Heading B5N. [Also in Divisions B2 and D2] A wear resistant structure is produced by forming a composite structure including a substructure having apertures therein arranged in a prescribed pattern and a smooth, continuous uniformly thick coating of hard ceramic material thereon, said coating spanning the area of the apertured portions of the sub-structure and subsequently applying pressure to the coated surface of the composite structure to duplicate therein the apertures of the substructure. The wear resistant structure may be the suction box covers found in paper making machinery. In an embodiment the coating is pre-formed by flame spraying ceramic oxide material upon a transfer member having a coating of a release agent e.g. polytetrafluoroethylene on its receiving surface. The coated side of the transfer member is cemented to the sub-structure by a thermosetting adhesive layer e.g. a fibrous mat formed of cellulose fibres impregnated with an uncured epoxy or phenolic thermosetting resin, or preferably a deformable thin fibreglass mat impregnated with a phenolic resin. The resulting structure is subjected to pressure which causes the thermosetting layer to fill any voids between the coating and the sub-structure and heated to cure the thermosetting layer. The coating and the sub-structure is then removed from the transfer member. To extend apertures in the substructure through the continuous layer of the pre-formed coating, pressure is applied to the outer surface of the coating by compressing a deformable and resilient medium against the exposed surface of the coating. A ductile metal layer may be interposed between the deformable medium and the exposed surface of the pro-formed coating.

Abstract: 1482026 Controlling light INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1974 [14 Jan 1974] 52642/74 Heading G2F [Also in Division H1] A thin film dielectric optical waveguide 12 has a transparent electrode 16 on a planar surface, and an electrode 14 on a corrugated surface, the corrugated surface acting to reflect a leaky light wave of the first diffraction order of a wave propagating in the guide so that it is transmitted out of the guide through the planar surface, a variable electric potential difference being applied between the electrodes to vary the refractive index of the waveguide material and hence to vary a parameter of the leaky wave. In a first embodiment a monochromatic laser beam is directed along the axis of the guide, the pitch of the corrugated surface being such that the second order diffracted beam does not exist, and variation of the refractive index alters the direction of the leaky wave. The guide may be of Ta 2 O 5  or liquid crystal material. In a second embodiment the guide is formed of light amplifying material and is optically pumped. The requirement that the second order diffracted beam coincides with the incident beam to provide feedback for laser action necessarily leads to a leaky wave at 90 degrees to the planar surface, the wavelength of the wave being controlled by the voltage between the electrodes, i.e. a tunable laser. Guide 12 may be a 16À3Á layer of glycerol containing Rhodamine 6G between an aluminized blazed diffraction grating and a quartz optical flat, and the pumping radiation may be green or ultraviolet light.
