Patent GB-1267088-A (GB)
IPC: G02B3/00
Filed: 1969-07-18
Abstract: 1,267,088. Stereoscopic photography. L. P. DUDLEY. July 18, 1969 [July 26, 1968], No.36220/69. Heading G2A. In a system for making stereoscopic photographs, the photograph is taken through a lenticular or line screen F, the images being formed on a layer of photo-sensitive material F on the back of the screen. The arrangement is such that the elementary images on the layer P each fill the image format of the corresponding lenticule, so that adjacent images are neither appreciably spaced apart nor overlapping. The purpose is to obviate or minimize moire effects. These considerations may apply to the lenticules themselves (which are arranged in rows and columns), so that arrangements of spherical lenticules with circular peripheries, however arranged e.g. Figs.25 and 26 (not shown), will not be satisfactory. As shown, the front surface of the screen is formed as an array of spherical lenticules with square peripheries, Fig. 14, although an array of spherical lenticules with hexagonal peripheries Fig.17 (not shown) may also be used. As shown, L denotes the primary or camera lens, which includes an apertured plate A located for convenience in the position normally occupied by the iris diaphragm. The plate has a square aperture (hexagonal in the Figs.15-17 arrangement, not shown), which may be made adjustable in size,  and serves to change the shape of the elementary images from circular to square (or hexagonal). The aperture may embody colour filters. The specification sets out and discusses the relationship which must exist between the characteristics of the lens L, the characteristics of the lenticules, and the dimensions of the aperture plate A, in order that the desired result may be obtained. The elementary lenticules may be formed by two sets of crossed cylindrical lenticules, and Fig.7 (not shown) is an equivalent arrangement formed by two sets of crossed line screens. An optical system for adapting the invention for working with image formats of small dimensions is described with reference to Fig.33 (not shown). The completed photograph (or integram), or a reproduction thereof, exhibits a stereoscopic effect when viewed through the lenticulated surface, or through another screen which matches that used in taking the picture.

Abstract: 1297021 Magnetic storage device THOMSON CSF 28 Jan 1970 [7 Feb 1969] 4192/70 Heading H3B A magnetic storage element, capable of non- destructive readout, comprises three superimposed magnetic layers 5, 7 and 1, the layer 5 having a square hysteresis loop, and high coercivity and being anisotropic with an easy direction along the line x<SP>1</SP>-x, the layer 7 being a soft magnetic material, and the layer 1 being a ferrite plate of lower permeability than the layer 7 and being grooved to contain orthogonal word and digit wires 11 and 21 respectively and possibly a read wire 31. In operation simultaneous pulsing of the word and digit wires provides a field H R  in layer 5, which after the pulse terminates and due to the low anisotropy of layer 5 results in a magnetism H D  in the easy direction. This flux closes through the highly permeable layer 7 (and not the plate 1) in a direction parallel to x<SP>1</SP>-x but in the opposite sense to that in layer 5. The sense of the magnetization in layer 5 along x<SP>1</SP>-x signifies a " 1 " or a " 0 ". To read the element the word wire 11 is pulsed causing the flux in the permeable layer 7 to rotate to the direction H M . The flux in layer 5 is now forced to close through the plate 1 inducing a pulse in the read wire 31. This pulse will go first positive or first negative depending upon whether a " 1 " or " 0 " is stored. On cessation of the read pulse the flux again closes through layer 5 thereby retaining the stored information. A copper layer is provided on top of layer 5 and an insulating layer is interposed between layers 5 and 7. The layer 5 may be Co or FeCo alloy or FeNiCo alloy, and the layer 7 may be 80/20 NiFe, or a NiFeCo alloy.

Abstract: 1351279 Automatic control of course FLUGGER€TEWERK BODENSEE GmbH 1 July 1958 21123/58 Heading G3R Steering of an air-to-air missile to collide with a source of light or infrared energy, e.g. jet aircraft tailpipes, is effected photo-electrically. A gyroscope in the missile is precessed automatically by the photo-electric system to maintain the axis of rotation directed towards the target; the inclination of the gyro axis to the missile longitudinal axis is detected and the resultant signal adjusts the missile control fins to turn the missile into alignment with the gyro and hence towards the target. In the gyroscope precession sytem a mirror, mounted on the rotor and inclined at a small angle thereto, reflects light (or heat) rays from the target to a photo-cell. The cell output energizes a coil of which the field interacts with a permanent magnet mounted on the gyroscope to cause it to precess until the axis is directed towards the target. The mirror rotating with the rotor produces an image which traces a circular path round the photo-sensitive device. The inner diameter of the path is such that a small displacement of the image path due to an error between the gyro axis and line of sight causes the image circle to touch the photo-sensitive device to produce the correcting signal.

Filed: 1970-05-09
Abstract: 1352465 Change-speed control; friction clutches BROCKHOUSE ENG Ltd 6 May 1971 [9 May 1970] 25819/72 Addition to F2 Headings F2C and F2D A lock-up friction disc clutch 20, in parallel with an hydrodynamic torque-converter on a motor-vehicle, is disengaged by a bias fluid pressure permanently supplied to one side of a clutch piston 22 to overcome a diaphragm spring 23, and is engaged by controllably supplying an equal balancing fluid pressure to its other side A, permitting the spring 23 to engage the clutch. The supply to the side A is controlled by an automatic centrifugal valve 32, which, in its radially innermost position, exhausts the side A through a port 45 and shaft passages 46, 51, causing clutch disengagement, whilst, in its outermost position, the valve 32 supplies pressure to the right side A from the constantly pressurized left side B through ports 42, 41a, 40, for spring engagement of the clutch. The outward centrifugal movement of the lock-up valve 32, for clutch engagement, is resisted by a bi-stable rapid movement means, comprising a spring-loaded plunger 35, Fig. 3, loading the valve 32 through a triangular lever plate 37, pivoted at 39 to a part 31 of the torqueconverter turbine 13, either parallel or tangential to the shaft axis, and engaging the valve 32 and load plunger 35 through rollers 38, which, during outward valve movement, cause the moment arm of the plunger 35 to decrease, whilst that of the valve 32 increases, the reverse occurring on inward movement, so that movement in either direction, once initiated, proceeds rapidly. Inward movement may occur at the same or a lower speed than outward. An override valve 50 in a passage 47 can be actuated manually or by a gear-shift lever, to connect the passage 46 to a pressure inlet passage 41 instead of to exhaust 51, to cause clutch engagement in a desired gear setting.

Title: Pneumococcal polysaccharide conjugate vaccine
IPC: C07K14/00
Filed: 1992-01-21
Abstract: A novel conjugate vaccine comprising partially hydrolyzed, highly purified, capsular polysaccharide (Ps) from Streptococcus pneumoniae bacteria (pneumococci, Pn) linked to an immunogenic carrier protein, is produced by a new process. The conjugate is useful in the prevention of pneumococcal infections. Vaccines comprising a mixture of from one to ten different pneumococcal polysaccharideimmunogenic protein (Pn-Ps-PRO) conjugates induce broadly protective recipient immune responses against the cognate pathogens from which the polysaccharide components are derived. Young children and infants younger than 2 years old, normally unable to mount a protective immune response to the Pn-Ps alone, exhibit protective immune responses upon vaccination with these Pn-Ps-PRO conjugates.

Title: Apparatus and method for reducing power consumption in a mobile communications receiver
Inventor: TIEDEMANN EDWARD G JR
IPC: H04B1/16
Filed: 1993-03-02
Abstract: A system for reducing receiver power consumption in communication system having a transmitter and one or more receivers schedules periodic messages in "slots." Each receiver is assigned a slot during which it monitors the transmissions. The transmitter transmits messages to the receiver only during the assigned slots. The receiver is in an "active state" during its assigned slot. It may remain in the active state after its assigned slot if the message requires the receiver to perform additional actions. During the "inactive state," which is the time period between successive occurrences of its assigned slot, the receiver may perform any action not requiring coordination with the transmitter. It may conserve power during this time by removing power from one or more components such as those used for monitoring the transmissions. At a time during the inactive state shortly before the assigned slot, the receiver applies power to these components and performs initializations. Such initializations may include reacquiring a pilot channel signal to which the receiver may synchronize itself if its timing signals have drifted out of synchronization with those of the transmitter during the preceding inactive state.
