Filed: 1974-09-02
Abstract: 1463676 Low pressure indicators for pneumatic tyres BRIDGESTONE TIRE KK 2 Sept 1974 [1 Oct 1973 12 Oct 1973] 38307/74 Heading B7C [Also in Division H4] A drop in tyre pressure below a predetermined value is sensed by a detector 17 which thus causes a radio transmitter 18, 64 to transmit a signal. The signal is received by receiver (24), (Fig. 1, not shown) via an antenna (23), and the receiver thus actuates an alarm device (25), e.g. a lamp, or a buzzer. The transmitter is mounted within a hollow casing 20, 51 positioned at the centre of the cover disc, and the detector is mounted on the valve stem 16, or is mounted on the disc and is in communication with the tyre cavity via the valve stem or via an aperture in the rim. The casing 20 may be employed as a transmitting antenna. In a modification of Fig. 2 the casing is mounted on the inboard side of the cover disc (Fig. 3, not shown). In the embodiment of Fig. 4, casing 51 is of non-conductive material, e.g. synthetic resin, and has a metal coating 54 on its inner and/or outer side. The cover disc may be of non- conductive or conductive material, and in the latter case the metal coating is insulated from the disc 50.

Title: Improvements in and relating to core structures for nuclear reactors
Inventor: PAGGI LAMBERTO
IPC: G21C5/08
Filed: 1959-11-12
Abstract: 965,209. Moderator structures. NUCLEAR POWER PLANT CO. Ltd., L. PAGGI. and J. OLIVER. Oct 13, 1960 [Nov. 12, 1959], No.38455/59. Heading G6C. A moderator core structure comprises an assembly of blocks of solid material, e.g. graphite, with keys 4 located in keyways 5 formed in the sides of the blocks and so disposed that the keys between any one block and the adjacent blocks lie in at least three different planes containing the central axes of the blocks. In the embodiment described, the blocks are of two different sizes,the smaller blocks 2 being of square cross-section and the larger blocks 1 of octagonal cross-section. The blocks are formed with keyways 5 in each side and are stacked in adjacent columns with keys 4 located in the keyways as shown in the plan view of Fig. 3. The keys 4 thus lie in four perpendicular planes spaced 45 degrees apart and containing the central axes of the blocks. The length of the keys 4 is substantially less than that of the blocks. The bottom layer of blocks is formed of alternate long and short blocks thus providing axial overlapping of adjacent blocks through a layer of the core. Leakage of cooling fluid from the fuel channels 3 of each block is prevented by the provision of spigots or sleeves extending from one block into the next in each column. The above-described structure is such that should shrinkage of the blocks occur due to Wigner changes, the spacing and alignment of the fuel channels 3 will not be affected. If necessary, the columns of blocks may initially have a small space separating them to allow for irradiation growth. Omission of a limited number of keys 4 is permissible and this permits the insertion of interstitial channels 6 (Fig. 3,) by suitably shaping the opposed sides of adjacent pairs of larger blocks 1. In an alternative embodiment, one or more keys in any one block form an integral part of the block. The sides of the core are surrounded and constrained by a metallic structure, the thermal expansion properties of which conform closely to those of the block material, each individual column of blocks being movably supported at its base on a steel plate by means of ball races interposed between the steel plate and a base support plate for the core. Where, however, the metallic structure containing the core has thermal expansion properties which conform closely to those of the base support plate, the individual columns can be fixed directly to the base support plate and the ball races dispensed with.

Abstract: 994,249. Angular bending. MASCHINENFABRIK AUGSBURG - NURNBERG A.G. Oct. 2, 1963 [Oct. 19, 1962], No. 38745/63. Heading B3E. An automatic pipe bending machine having a machine frame at the two ends of which a mandrel holder and a bending unit are disposed opposite to one another and a carriage running on the machine bed between the holder and unit which carries a rotatable chuck, characterized in that the longitudinal and rotational movements of the chuck are controlled by a command apparatus adapted to move with the carriage and controlled by a command carrier guided along the machine frame. The machine comprises a bending segment 2 with clamping jaws 6, a bending mandrel 5 on a draw rod 4 mounted on a carrier 3 and a carriage 7 driven by a motor 8 driving spindle 9 on which is mounted a rotatable chuck 10 driven by a motor 11. Bobbins 12 are fitted with a command band 13 which has contact or light gap tracks 14 to 19, e.g. rows of perforations, which in conjunction with a command apparatus 20 having light sensitive or contact means regulates the movement of the machine. In operation with a pipe clamped in the chuck 10 the motor 8 is started by a switch to effect movement of the carriage 7 away from the carrier 3, at a predetermined position the command unit, e.g. via track 14, stops the machine through a magnetic clutch and causes the end of the pipe 4a to be clamped to the bending segment 2, e.g. via track 15, the carriage movement restarts and the bending segment rotated a predetermined amount at which point the command unit again stops the machine. The mandrel carrier 3 is subsequently operated, e.g. via track 16, to withdraw the mandrel 5 so that the pipe can be released from the segment 2 and re-positioned in readiness for another bend. If a spatial bend is to be made the chuck 10 is rotated to the right or left via segments from tracks 17 or 18 to its drive motor 11 whilst the carriage 7 continues to run until the desired rotation is completed at which point the chuck and carriage are stopped, the pipe re-clamped to the segment 2 and the bending operation is carried out as before. Track 19 may be used to control rapid movement of the carriage when long straight lengths of pipe lie between two bends. Sample pipe forms may be used to facilitate marking of the command band. The bobbins remain stationary during the pipe bending operations but are rotated to reposition the command band when different shaped pipes are required.
