Title: Breaker bolt
IPC: B21B21/00
Filed: 1967-09-20
Abstract: 1,202,067. Breaker bolts. SANDVIKENS JERNVERKS A.B. 20 Sept., 1967 [22 Sept., 1966], No. 42854/67. Heading F2H. A bolt assembly for use as a breaker bolt to limit the load to be sustained thereby comprises a bolt 4 having two abutments 10, 21 thereon, a frangible part 13 between the abutments which is breakable at a predetermined load and means for pre-stressing said frangible part by a load just less than said pre-determined load. In one embodiment a sleeve 17 is provided around the unthreaded portion of bolt 4 and a nut 16 is threaded on to the sleeve, a further nut 10 being threaded on the threaded part of bolt 4. Prior to use in a machine assembly the bolt 4 is  stressed to a load just below the fracture load and the nut 10 tightened against ring 11, disc 13 and a further ring 12 which bears against sleeve 17 which in turn bears against abutment 21. When the bolt is assembled in the machine part, the nut 16 is screwed down against a bearing face on a machine part 1 the head of the bolt being connected to a second machine part. Variations in pressure between the two machine parts are not transmitted to the bolt as long as they are below the pre-load applied to the bolt. However when the pressure is greater than this load and the fracture level is reached the disc 13 breaks causing the ring 11 to slide into the ring 12. In a further embodiment the bolt is formed in two pieces with a frangible member therebetween and the sleeve extends between the two abutments one of which is formed by a nut threaded on to the bolt (Fig. 4, not shown).

A guide member 15, which is separate from the inner valve seat and extends centrally through the valve member 17, is formed of plastics, ceramics or an alloy with a lateral flange 26 for limiting the movement of the valve member inner periphery, and with two sets of flow conducting channels 20 and 23. The guide member and washer element 25 are clamped together and are clamped between the piston 10 and an annular limit stop member 14, by way of a nut 11a secured to the piston rod 11. In a modification, Fig. 3 to 5 (not shown), the washer member may be fitted around a concentric projection (28, Figs. 5) of the guide member. Alternatively, Fig. 6 (not shown), the washer member may be omitted and the stop member 14 arranged to provide the inner valve seat.

Title: Pneumatic tyre
IPC: B60C3/08
Filed: 1970-09-08
Abstract: 1318406 Pneumatic tyres YOKOHAMA GOMU KK 8 Sept 1970 [14 May 1970] 42955/70 Heading B7C A pneumatic tyre comprises a pair of laterally spaced bead cores 11 and an annular flexible carcass 12 which comprises a plurality of elastomer-coated fabric plies 16, 17 and includes a circumferential tread region 13 with a pair of marginal shoulders. The tyre has an outwardly swollen rim cushion region D, which is thicker than its associated sidewall 14, adjoining each of the bead cores, 11. Opposing sidewall regions 14 extend between the shoulders 22 and the rimcushion regions D and, in the moulded state, each of the sidewall regions 14 consists of a sloped portion A merging with its associated shoulder 22, a substantially straight portion B and a fold C which extends circumferentially of the tyre carcass and adjoins its associated rimcushion region D. The fold C is adapted, when the tyre is mounted on a rim with the bead cores 11 axially closer together than in the moulded state, to fold resiliently the sidewalls 14 on themselves axially of the tyre, and to define a continuous U-shaped channel opening to the outer surface of each sidewall 14. When the tyre is deflated to a collapsed condition, the position of each fold C is such that the outer surface of the associated bead core 11 substantially underlies the associated marginal shoulder 22 of the tread region 13. The tyre of the invention may be built by the "flat-band" method and the resulting green tyre 10 may be vulcanized using a conventional vulcanizer. The plies 16, 17 may be of nylon, rayon or polyester.

Abstract: 881,297. Securing bearing-races on shafts. ALUMINIUM-INDUSTRIE-A.G. Dec. 21, 1959 [Dec. 24, 1958], No. 43357/59. Class 80 (2). [Also in Group XXXIV] In a rolling mill the roll journal 2 is supported by a journal bearing 3 and a ball or like thrust bearing 4, the inner race of which is connected to a yieldable device for rotation therewith. Deflections at the end of the roll are absorbed by the yieldable device, and the bearing 4 takes only the axial thrust. The device comprises a rod 5 secured by a flange to the end of the roll and a tube 6 integral with the inner race of bearing 4. The free ends of these members are connected and both are capable of transmitting axial stresses to the bearing, lens are sufficiently elastic to take up radial deflections. In a modification, the rod 5 is connected to the roll 2, and the tube 6, by a ball and socket joint 9, rotary motion being transmitted by pin 58 in the balls which engage wedges in the sockets (not shown).

Abstract: 1,206,782. Colour television test apparatus. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Sept., 1967 [27 Sept., 1966(2)], No. 43519/67. Heading H4F. A colour bar generator, Fig. 5, comprising multivibrators 3, 4 and 10 which operate respectively at once, twice and four times line frequency and which are interconnected through differentiators D and triggered by synchronizing pulses 1 so as to furnish waveforms as shown in Fig. 2, is utilized to control gates 7, 8 and 9 in a colour carrier generator circuit, Fig. 3, in which quadrature-phase carrier signals FHT are phase split in transformers 1 and 2 to produce signals at the R-Y and B-Y angles and these signals are then combined in matrix circuits 3, 4 and 5 to provide signals for the gates at R, G and B angles. The final signal is combined in a stage 12 with a signal Y representing a predetermined luminance value. The arrangement may operate selectively to provide an N.T.S.C. or P.A.L. type of signal by causing the carrier signal applied to transformer 1 to have either a fixed phase or a phase which is changed by 180 degrees for alternate lines. A colour synchronizing signal is derived with the aid of matrix circuit 6 and applied to a fourth gate 10 which is controlled by a "burst" interval signal. The synchronizing and "burst" signals, together with a signal at half-line frequency for operating a switch to change the carrier phase by 180 degrees where a P.A.L. signal is produced, may be provided by an internal generator of suitable stability or an external generator. The gate circuits may each comprise a transistor, Fig. 4 (not shown), with the gate control signal applied to the base and the carrier signal applied to the emitter across a resistor which forms the output resistor of the associated matrix circuit.

Title: A selector switch for controlling relays arranged in a switching matrix
IPC: H04Q3/00
Filed: 1964-10-28
Abstract: 1,079,932. Automatic exchange systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Oct. 28, 1964 [Nov. 2, 1963; Feb. 14, 1964], No. 43951/64. Heading H4K. The contact operating coils of multi-armature relay selector switches, such as described in Specification 891,873, are connected into matrices for selective operation by marker switches. The coils are connected at the matrix cross points in series with rectifiers. Pulses transformer coupled to a row and column wire simultaneously are sufficient to overcome a back bias on rectifiers associated with each row and column wire. A coil is identified by the matrix in which it is situated as well as its row and column co-ordinates. As shown in Fig. 2, each row and column wire of each matrix 1 to k can be supplied with a marking voltage by an output winding of a transformer U1 to U4. The output windings of each transformer supply the corresponding row and column windings in each matrix. In selection of a required matrix one of the contacts M1 to Mk is closed to connect a back biasing voltage into a path common to all the row wires of the matrix. The two transformers corresponding to the wanted row and column wires are selected by the coincidence of row and column pulse trains J1 and J2 on two cores in a saturable core matrix K1 to K4. The alternating output of the cores switch transistors Ts1, Ts2 to provide an alternating input to the selected transformers. The rectifiers and centre taps of the output windings of the transformers provide a full-wave rectified output to overcome the bias and operate the relay.
