Title: Improvements in or relating to control means for a vehicle seat having an angularly adjustable back
IPC: B60N2/22
Filed: 1964-08-05
Abstract: 1,077,467. Seats. AMERICAN METAL PRODUCTS CO. Aug. 5, 1964 [Aug. 5, 1963], No. 31785/64. Heading A4J. [Also in Division E2] A seat back 32 is releasably maintained in a selected angular position relative to an intermediate seat frame (30), Fig. 4 (not shown) by means of a slide rod 90, Fig. 5, which is pivoted at 44 to frame (30) and is reciprocal in a housing 96 secured to seat back 32. A spring 102 urges housing 96 towards the position in which seat back 32 is upright. Friction discs 130, 132 are urged by springs 146, 148 into a position inclined relatively to rod 90 so that the inner peripheral edges of the discs bite into the rod. A control cam 145 is provided which is movable into either of two alternative operative positions in one of which angular movement of the seat back relative to the seat is permitted in the rearward direction only and in the other operative position the seat back can only be moved forwardly. If cam 145 which as oppositely inclined control surfaces 143, 144 is rotated in one direction, Fig. 10 (not shown) discs 130 are moved into an orthogonal relationship with rod 90, so that housing 96 can move upwardly but downward movement is prevented by edges 166, 168 of discs 132 which bite into rod 90. On rotation of cam 145 in the opposite direction discs 132 are straightened to permit downward movement of housing 96 relative to rod 90, the biting edges 162, 164 of discs 130 preventing upward movement of housing 96 relative to rod 90. Intermediate frame (30) is U-shaped and comprises a back bar hinged at 60 to a back bar 70 of seat back 32, and a pair of curved arm portions 36 each pivoted at 40 to seat frame 22, Fig. 3, to permit forward tilting of the seat back.

Title: Process for making polycarbonates
IPC: C08G64/40
Filed: 1963-08-14
Abstract: Polycarbonates are recovered from solution by adding sufficient solid polycarbonate to the solution to convert the entire resulting mixture to the solid phase.  Preferably mixing is effected in a sigma blade mixer or a pug mill.  The solid polycarbonate may be heated up to 145 DEG  C. before mixing and the polycarbonate solution may be heated in the mixing apparatus to evaporate some of the solvent.  The precipitated polycarbonate may be heated in an oven or tumble dryer to remove the remainder of the solvent.  Examples describe the recovery of bisphenol A polycarbonate from its solution in methylene chloride or ethylene dichloride.

Abstract: 1,081,132. Depth charges &c. FIJN MECHANISCHE INDUSTRIE BECKER'S SONS N.V. Aug. 6, 1964 [Aug. 6, 1963], No. 32136/64. Heading F3A. A hydrostatically operated detonator has a spring-loaded striker pin 7 locked by a rod 16 connected to a membrane 20 sensitive to hydrostatic pressure, the rod releasing the pin by movement against a spring 18 adjustable to correspond to a valve of the hydrostatic pressure at a desired water depth. A striker pin 7 and its holder 13 are movable under the influence of a spring 8 but in the safe position are held locked by balls 14 engaged in a groove 15 in the holder 13. Water enters via apertures 30 to move the membrane 20 and the rod 16 against the spring 18 until the balls 14 can enter a recessed portion 17 of the rod to release the holder 13 and pin 7 which strike the detonator; apertures 35, 36 allow for the escape of air compressed by the membrane. The case 19 is shaped with a narrow diameter portion between its ends to facilitate gripping in the hand. The rod 16 is locked prior to use by a withdrawable forked member 32. For safety should the projectile fail to reach the desired depth the screw connection 24 is made to leak slowly so that in time the pressure is equalized on both sides of the membrane.

Title: Methods of and apparatus for ascertaining the characteristics of motion of inaccessible moving elements
IPC: A61B8/08
Filed: 1974-07-24
Abstract: 1510306 Investigating motion L KAY 21 July 1975 [24 July 1974] 32661/74 Heading G1G [Also in Divisions H3-5] Motion of an element within a living body is investigated by transmitting a frequency swept acoustic signal into the body, mixing resulting echo signals from the element with a local frequency swept electrical signal to derive a difference frequency signal, and transducing the latter to an audible signal having discernible variations indicative of both the magnitude and velocity of movement of the element. In the embodiment described the transmitted signal is a repetitive, linearly rising, frequency sweep and the echo signal, from e.g. the heart, is heterodyned with a replica of the transmitted signal to give the difference frequency signal. This is extracted by a filter and fed to an earphone or to a portable tape recorder (for later use with the earphone). The difference frequency depends both on the (changing) range of the echo-producing element and (due to the Doppler effect) on the rate of change of range. Directional transducers (see Divisions H3-5) are used for transmission and reception.

Title: Improvements in or relating to "anti-dazzle" devices, suitable for the use of vehicle drivers
IPC: B60Q1/34
Filed: 1928-11-09
Abstract: 325,000. Rolph, W. M. Nov. 9, 1928. Anti-dazzle screens.-In an anti-dazzle device for the use of vehicle drivers of the kind comprising a series of pivoted strips of translucent material adapted to be spread out in use or to be collapsed, a spring is provided to move the strips to their operative position, while a catch retains them in a normal inoperative position. In the construction shown the strips 1-8 are attached at their inner ends to holders 9 pivotally mounted on a sleeve 10 which serves as a distance-piece between the front and rear plates 11, 12 of a casing adapted to receive the strips when collapsed. A spring 21 is connected at one end to a pin 15 on the first strip 1, and the holders 9 are formed with apertures 22 and co-operating stamped-up tongues 23 of smaller width than the apertures so that movement of the first strip 1 causes the remaining strips to be successively operated. The rear plate 12 of the casing is made of a springy nature and provided with a pressed-up portion 20 which serves as a catch to retain a finger lever 17 movable with the strip 1. Thus, when the plate 12 is pressed inwardly by the operator, the finger lever 17 is released and the spring 21 functions to spread the strips 1-8, the latter being returned to the casing by moving the lever 17 by hand until it snaps behind the catch 20. Each of the strips 1-7 is preferably formed with a projection 32 on one edge forming an additional overlap to the adjacent strip. The casing is mounted on a windscreen pillar or similar support in a readily detachable manner by the provision of suction cups 25, 31 or by forming the casing or support with key-hole slots adapted to pass over studs on the support or casing. In a modification, the successive operation of the strips 1-8 is effected by means of af pin which engages arcuate slots of successively increasing length in the strips.

The term "stimulus value" denotes a measure of the noticeability of the spot, and depends on the size, brightness and direction of the spot. All equally noticeable spots have the same stimulus value. An indication of the correctness of a response, e.g. audible may be provided to the subject. A computer program is described which controls the process, and enables display of the field of vision, determination of vision threshold contours and plotting the shape of the blind spot. The program includes a routine for identifying which eye is under test by applying a spot which should be in the blind spot of the right eye. A number of spots which should image on the blind spot may also be applied to determine the degree of fixation of the subject.
