Title: Disc type brake structure
IPC: F16D55/14
Filed: 1961-04-05
Abstract: 913,624. Disc brakes. LAMBERT BRAKE CORPORATION. April 5, 1961 [April 8, 1960], No. 12237/61. Class 103 (1). A disc-brake actuating mechanism comprises two discs 70, 72 moving apart on relative rotation, and first 106 and second 112 links pivoted each on a disc at one end 108, 114, the second link 112 being pivoted at its other end to an intermediate point 120 of the first link which is movable outwardly at its other end 132 to relatively rotate the discs. Relative rotation of the discs 70, 72 produces axial movement against retraction springs by balls 78 riding in camming recesses 74 to brakefriction discs 48, 50, splined on shaft 22, against stationary surfaces on an annular plate 28 and a housing 26 rigid with a frame member 24. Stop-pins 86, 92 restrain torque on the actuating discs 70, 72, the axial movement of which is allowed in the linkwork by oversize holes in the links for the pins 108, 114. Specifications 583,108 and 853,845 are referred to.

Title: Improvements in or relating to brake and acceleration testing means
IPC: G01L5/28
Filed: 1937-04-30
Abstract: 494,733. Accelerometers. HUDLASS, F. W. April 30, 1937, No. 12370. [Class 106 (iii)] Brake and acceleration testing means comprises a member adapted to rest on the floor of a motor vehicle, the member being so dimensioned that the falling forward of the member when the brakes are applied gives a measure of brake efficiency. A block which may be solid or hollow and closed or open at the ends is dimensioned in the proportion of 3<13>/15 x 2<11>/16 x 1<11>/16. When placed on the floor of the vehicle with the wide face A square to the direction of motion, if; when the brakes be applied at twenty-five miles per hour, the block fails to topple over, the brakes need immediate attention. If the block topples, it is placed with the face B square to the direction of motion and a test is made at the same speed as before, toppling of the block indicating satisfactory braking. If the block does not topple the braking is only fair and the brakes should be adjusted. The blocks may be pivoted to a base which rests on the floor of a vehicle. In further modifications boxes or tubes are telescopic and the inside member marked to show percentages of braking efficiency. The outer member in these forms may be pivoted to a base member. The device may comprise an outline of a human or other figure mounted on a stand, or such figure or advertising matter may be arranged on the face of the device. The device may be of polygonal section. It may be made of metal, wood, ebonite or synthetic resin.

Title: A Resilient Column
IPC: G21C5/10
Filed: 1967-03-16
Abstract: 1,154,763. Moderator structures. SOC. DES FORGES ET ATELIERS DU CREUSOT. 16 March, 1967 [30 March, 1966], No. 12492/67. Heading G6C. A resilient column for use as one of a number of identical pillars beneath the core supporting platform of a nuclear reactor comprises a rolling element 1 formed by a flat panel having two part-cylindrical surfaces bearing on two resilient base units 2, each unit 2 having a triangular cross-section with the apex truncated to form a plane zone 2a, the two edges parallel to the apex each having a band 2b by way of which the unit 2 bears on a plate 3 so that a gap d remains between the unit 2 and the plate 3. The bottom plate 3 bears on a footing 5 integral with the foundations, with the interposition of two discs 4 having slightly inclined contacting surfaces 4a. By varying the orientation of the two discs 4, the bottom plate 3 can be adjusted vertically. The bottom plate 3 is immobilized by a spigot 6 screwed into the plate 3 and centred in the footing 5. The top plate 3 serves as the bearing for a screw-threaded sleeve 7 which screws into a nut 8 rigidly connected to a ring 9 bearing the load distributed between all the columns, and is immobilized by a spigot 11 screwed into the plate 3 and centred in the sleeve 7. The rolling element 1 is retained relatively to the base units 2 at each end by a tooth 12 secured to the corresponding plate 3 and engaging in a tooth space 13 in the element 1. When the load is placed on all the columns, the nuts 8 can be operated to ensure that all the columns are placed under load simultaneously. The two resilient base units 2 of each column experience a bending proportional to the load borne, which bending can be measured by the insertion of thickness gauges into the gaps d, and the nuts 8 can then be adjusted in the required direction to ensure that the load is distributed uniformly.

Abstract: 1310935 Laminated products ARTHUR D LITTLE Inc 16 March 1970 [11 April 1969] 12627/70 Heading B5N [Also in Division D1] Apparatus for producing a laminate having a non-woven net layer comprises at least one pair of parallel endless chains or belts 21 carrying strand anchoring pins 20, at least one shuttle 46 carrying hollow tube strand guides 66 and drive means for moving chains 21 and reciprocating shuttle 46 so as to lay the strands between the rows of pins 20. The strand guides 66 are separated by the same interval as the pins 20 on each chain, or by a whole number multiple thereof. The shuttle is guided by parallel track members extending transversely across the spacing between chains 21 and is reciprocated by pivotably attached rods 70. The strands (threads, monofilaments or yarns) are anchored by each guide 66 passing outwardly between adjacent pins 20, around the outside of at least one pin (due to the forward motion of the pins) and returning through an interval between following pins. Preferably a second shuttle 96 halves the net mesh size by laying threads between pins 34 mounted above pins 20. Pins 34 may be carried by endless chains 35 running outside the chains 21, as shown, or vertically above them (Figs. 12-14, not shown). Although bonding of the strand crossover points is mentioned, the net is preferably calendered between paper strips 154, 159, the latter bearing adhesive 170 applied by roller 166. The threads are then cut by knife (174, Fig. 3, not shown), freezing the laminate for passage over cooling roll 181 and takeup on roll 182.

The sizes of the ducts 2 and 6, and the position of the support element 3 are adjustable to suit various sized springs. The pistons are pneumatically operated and the signals are generated in a pneumatic circuit. In a further embodiment, Figs. 6 to 9 (not shown) the springs are supplied from the feed duct singly into a support for sensing, whereafter the support is slideable into alignment with a spring gripper, and the spring is moved into the gripper by a piston on the support.

Title: Getter
IPC: G21C3/17
Filed: 1974-05-02
Abstract: 1467269 Gettering GENERAL ELECTRIC CO 2 May 1974 [9 May 1973] 13139/75 Divided out of 1467268 Heading H1D A composite getter comprises a metallic substrate at least partially covered by a coating of a material capable of gettering reactive gases, the substrate having a greater coefficient of thermal expansion than the coating and being capable of producing tensile stress in the coating during thermal expansion, whereby the coating is intermittently fractured by changes in temperature of the getter to thereby expose fresh gettering surfaces in the coating. The getter is especially suitable for use within nuclear reactor fuel elements, in particular for the removal of hydrogen, water vapour and other hydrogencontaining gases. The coating develops a protective film, e.g. an oxide film, with the passage of time and this film when at reactor operating temperatures periodically fractures so exposing fresh portions of the coating to any reactive gases. With further passage of time, the fractures of the protective film grow into cracks in the coating exposing further portions of the coating. Suitable coating materials are Zr and Zr alloys, while the substrate may be comprised of Ni, Ni alloy, Fe alloy, stainless steel, Ti or Ti alloy. The substrate may be in the form of a strip, with a coating on one or each side, a cylinder or discrete particles.
