Title: Gyroscope processing apparatus
IPC: F41G7/22
Filed: 1975-09-01
Abstract: 1497065 Gyroscopic apparatus DEFENCE SECRETARY OF STATE FOR 1 Sept 1975 [3 Sept 1974] 38477/74 Addition to 1351873 Heading G1C In an improvement in or modification to the invention disclosed in Parent Specification, the gyroscope is incorporated in a stabilized housing head for a guided missile, mechanical linkages connect the control arm to at least two force motors, there being provided means for measuring precession of the rotor and means for rotating the sensor that is mounted in a sensor gimbal frame in synchronism with the rotor precession. As described, the force motors are solenoids 118, rotor precession being measured by monitoring movement of the solenoid armatures, the sensor 126 being rotated by electrically powered torque motors 130, 134 which receive signals proportional to rotor precession. The signals may be in terms of linear displacement, e.g. displacement of solenoid armatures from mean positions, or rate of displacement obtained by measuring solenoid currents. As shown the gyroscope 100 is as described in Specification 1351873, and is mounted on a plate 122 rigidly secured to guided missile structure 123. Four solenoids 118 operating in pairs apply precessing forces at right angles, the armature of one solenoid in each pair being connected to a position transmitter 125 by a rod 124. The sensor 126 and gyroscope 100 are locked by mechanism 135, for storage and carriage purposes, comprising a spring- biased piston 137 the head 138 of which bears on ball bearings 140 in apertures 141 in cylinder 136. The ball bearings contact a member 142 on the gyroscope and a member 142 on the sensor 126 locking them aligned with the missile axis, a catch (not shown) holding the piston until released after the operating speed of the rotor is achieved. The sensor gimbal frame may comprise a two ring system as shown, each-ring incorporating two pivots. Alternatively, Figures 9 and 10 (not shown), two frames (227), (231) each incorporating a single pivot may be employed. In use, the rotor precesses after unlocking, thereby causing movement of the sensor 126. The sensor 126 locks on to a target signals thereto and therefrom passing through nose section 150. Signals representing target motion relative to the missile are passed from the sensor 126 to a missile control computer which controls the electrical inputs to the solenoids 118 and also the missile aerodynamic control surfaces to direct the missile to the target.

Title: Process for treating regenerated cellulose yarns and cords
Inventor: HEUVELEN JOHANNES JACOBUS VAN
IPC: C08J5/06
Filed: 1965-09-17
Abstract: Regenerated cellulose yarns and cords are treated with an aqueous solution containing 0.3-3% by weight of borax which has been adjusted to a pH of 6.5-7.7 by the addition of a buffer and then dried, to reduce their tendency to creep when used for reinforcing rubber products, e.g. tyres.  The cords or yarns may be treated with the aqueous borax solution while in the wet or dry state, while travelling or wound on a spool or in the form of a spinning cake. They are preferably treated immediately after spinning, stretching and washing prior to drying, i.e. while still in the gel state, while passing them through a finishing bath or by spraying in conjunction with the finishing liquid, or may be stretched after treatment with the borax solution.  The buffer may be a mixture of mono-sodium ortho phosphate and di-potassium ortho phosphate, tri (hydroxymethyl) amino methane, triethanolamine, maleic acid or boric acid and the solution may also contain wetting agents, agents which improve the adhesion of yarn or cord to rubber and agents which improve the resistance to heat and/or light of the yarns.  Yarns may be treated while in the twisted or untwisted state, the twisting being effected while the yarns are still wet or after drying.  Two or more yarns treated with the borax solutions may be twisted together to form a cord prior to or after drying.

IPC: G01P15/135
Filed: 1957-12-30
Abstract: 850,945. Inertia switches, switch contacts. UNITED STATES ATOMIC ENERGY COMMISSION. Dec. 30, 1957, No. 40312/57. Class 38 (5). [Also in Group XIX] An accelerometer housing 1 rotatably supports an electric motor stator element 10 for angular displacement in response to acceleration of the housing in a given direction, a rotor 22 being adapted upon energization to oppose the angular displacement of the stator 10, and contacts operably connected to the stator control energization of the rotor in response to the angular displacement. The stator 10 is supported by shafts 7, 8 in bearings 2, 3 of housing walls 4, 5, and is provided with an enlarged flywheel encircling portion 11 which carries a weight spaced from the axis 7, 8. The weight and the axis 7, 8 normally lie in a plane at right angles to the direction in which the device is to be accelerated. When the device is accelerated, the weight causes the stator to rotate and turn a commutator 15 fixed to the shaft 8 so that a conducting segment 16 (Fig. 5) embedded therein makes contact with a stationary brush 17. Lead 53, which is connected to one side of a source of supply, is thus connected via segment 16, jumper 55, segment 57 and lead 24 to one side of the rotor 22, the other side of which is connected to the other side of the source of supply via lead 25, segment 67 and lead 70. Energization of the rotor 22 causes it to rotate in the same direction as the initial rotation of the stator, so that the reaction force acts on the stator to return it to its initial position thus breaking the contact between the segment 16 and brush 17 and de-energizing the rotor. Continued acceleration causes the contacts 16, 17 to be again made and broken and as long as acceleration continues the rotor 22 continues to be intermittently energized and itself accelerates in proportion to the linear acceleration of the housing 1.

Abstract: 1411540 Photo-electric colorimeters PAINT RESEARCH ASSOCIATION 24 Nov 1972 [27 Aug 1971] 40373/71 Heading G1A [Also in Division G2]  In a colour measuring apparatus in which light reflected from a surface being monitored is gathered by a plurality of light guides 14, the light issuing from each light guide is divided into a number of portions (36), Fig. 3 (not shown), each portion is incident upon a different wavelength filtering part of a filter 50 whose absorption wavelength varies across its width, and the light passing through the filter is incident upon a photo-cell 60 whose output is indicative of the colour of the surface. The divided light guide ends (36) are directed to the slits (42) in a mask 40, each slit corresponding to a band-width of about 20nm for a filter 50 whose absorption wavelength varies from 400 to 700 nm. Thus each slit receives light from all the light guides and directs this light to the corresponding portion of the filter 50. Between the mask and the filter is located an arrangement 44 of parallel neutral filters, one for each slit in the mask 40. The density of each neutral filter is chosen so that the output from photo-multiplier 60 represents one of the three primary stimuli X, Y, Z of the C I E standard observer, or some other colour function. To derive the other two stimuli, two different neutral filter arrangements 44 are used. The filter arrangement 44 may be replaced by an array of adjustable slits, and the intensity at each wavelength may be monitored in turn by employing a shutter with a slit. The ultraviolet fluorescence properties of samples may be monitored.
