Abstract: 780,765. Pneumatic tyres. PIRELLI SOC. PER AZIONI. March 4, 1955 [March 5, 1954], No. 6512/55. Class 144 (2). An inextensible breaker structure of a pneumatic tyre having a carcase of one or more plies of parallel rubberized threads cords or wires disposed in, or at an angle not exceeding 10 degrees to, radial planes containing the tyre axis, comprises one or more superposed pairs of superposed layers or juxtaposed layer sections, of substantially inextensible rubberized threads, cords or wires laid side by side in the layers, or each layer section, at an angle to the midcircumferential plane of the tyre with those in the overlying layer or layer sections crossing, and being individually continuous at each edge with, those of the overlain layer or layer sections. As shown in Fig. 3, a breaker strip may be formed by flattening a tube built up from a helical winding of a group of parallel cords, or a cord fabric strip, so that a double layer strip is formed with the lateral ends of the cords in each layer integrally connected with the ends of the corresponding, oppositely directed, cords in the other layer. One or more superposed turns of such double-layer strip may be spirally wound on the tyre carcase to provide the breaker structure. Fig. 6 shows an arrangement whereing the breaker structure is formed from a strip of longitudinal parallel cords, or cord fabric, obliquely bent upon itself in zig-zag fashion to provide a series of half-lapped parallelograms, the cords of each of which are oppositely directed to, and integrally connected with, the cords of adjacent parallelograms. A similar arrangement may alternatively be achieved by a progressive winding of a continuous cord, or group of cords laid zig-zag fashion across the carcase crown, or on a collapsible former, as shown in Fig. 7, one or more complete windings being effected as desired. Specifications 700,435, 726,810,755,990, and 772,232, [Group XXXVI], are referred to.

Title: An improved signalling system
Inventor: KILMINSTER SHIRLEY ANTHONY
IPC: G08B1/08
Filed: 1963-02-19
Abstract: 1,006,188. Selective signalling systems. HADLEY TELEPHONES & SOUND SYSTEMS Ltd. Feb. 19, 1964 [Feb. 19, 1963], No. 8569/63. Heading G4H. In a calling system, e.g. for a hospital, hotel or factory, momentary operation of a switch 10 at a remote station 1 energizes a corresponding indicator, such as a gas tube 5, at a central station 3, and operation of a switch 11 cancels the indication. The voltage of a D.C. source connected across terminals 8, 14 is insufficient to fire tubes 5, but is greater than that required to maintain the discharge once established. An A.C. source is connected across terminals 14, 16, but since the cold resistance of lamps 4 is low compared with that of resistors 15, a very low A.C. voltage is applied to the cathodes of tubes 5, and the tubes 5 are normally non-conducting. When a call is made from a station 1 by opening contacts 10, the cathode of the corresponding tube 5 is able to follow the negative peak of the applied A.C., and the tube fires to indicate which station 1 is calling. Lamp 4 is also lit to inform the caller that the indicator at the central station is functioning. Opening of contacts 11 allows the cathode of tube 5 to follow the positive peak of the applied A.C. and the tube is then extinguished. Tubes 5 may be replaced by silicon diodes in series with lamps, repeater indicators 17 may be included as shown, and an audible signal device may be inserted at 18 to give warning when any of the remote stations are calling.

Title: Improvements in Transfer Stations for Regulating Industrial Units
IPC: G05B15/02
Filed: 1968-02-09
Abstract: 1,197,142. Automatic control systems. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. Feb.9, 1968[Feb.10, 1967], No.6671/68. Heading G3R. In a control system for an industrial process of the type comprising a plurality of regulators each controlling a respective variable of the process under the supervision of a digital computer which is connected to the regulators in a numerical multiplex manner, Fig. 4 (not shown), a respective transfer station 3 is provided for the regulation of each variable and comprises a first regulating loop including the computer 2 and a storage circuit 31 and a second regulating loop K1, 33 with proportional action which produces a signal V to control the variable of the process 4. The computer 2 is fed with a set-point signal Co representative of the desired value of the variable, with a signal M representative of the measured value of the variable and with the co-efficient K2 of integral action which is related to the coefficient K1 of proportional action of the second regulating loop. The computer is programmed to produce at fixed sampling intervals of time, a signal U which relates the parameters Co, K2 and the sum of the regulation deviations preceding the considered sampling interval, the last mention mentioned parameter being derived from the signals Co and M applied to the computer. The analogue signal U is memorized in the storage circuit 31 under the control of selection pulses S controlling the multiplexing of the different stations connected to the computer. The circuit 31 derives a modified set point signal Cm which is similar to the signal U and is applied to a comparator 32 for comparison therein with the signal M, the error signals so produced being applied to the amplifier K1 whose gain corresponds to the co-efficient Kl. Member 33 is a function switch providing for change over from automatic to manual control. The modified signal Cm is such as to compensate for the static deviation of the second regulating loop. The circuit for obtaining the signals U and Cm is described, Fig. 2 (not shown) and comprises basically a series combination of a comparator, a sampler, an amplifier and an integrator whose output feeds the storage circuit 31 through a further comparator. The circuit 31 comprises a relay controlled by the pulses S and an operational amplifier shunted by a capacitor, Fig. 5 (not shown). Should the station 3 become isolated from the computer, proportional regulation is retained at the setpoint value existing immediately prior to isolation. The operation of the second regulating loop during such isolation is discussed. Fig. 3 (not shown).

Filed: 1925-03-12
Abstract: 246,688.. Cooke, L. H. March 12, 1925. Plumb-bobs. - In a plumb-bob for precision surveying instruments, particularly for use in centring the odolites &c., the point and suspension head are carried by parts connected together so as to allow of rapid relative adjustment in height. In the form shown the bob a carrying the point b is formed with an upwardly-projecting hollow cylindrical stem which is internally threaded along its upper part, and the suspension head e has a long cylindrical shank f passing through the stem c and threaded along its upper part to engage the threads in the stem. Adjustment is effected by screwing the bob along the shank f and lateral play in any position is avoided owing to the parts c, f having contact over uninterrupted cylindrical surfaces along a substantial part of their lengths. Air passages h are provided to equalize the pressure within the stem c during adjustment. To compensate for errors due to exaxiality of the point b in relation to the line k, the head of the bob is fitted with a swivel allowing the bob to be turned in azimuth so that readings in angular positions 180 degrees apart can be taken and the mean determined. One form of swivel is shown in Fig. 4, wherein the head e has a flange q and is encircled by a flanged ring o with which engages the stationary cap n through which the line passes. The rims of the flanges q, o may carry markings, graduations &c. to facilitate turning the bob through the desired angle. The arrangement of Figs. 1 and 2 may be reversed, the shank f being formed in the bob a and the stem c on the head. In another form the suspension head and the bob have co-operating plain cylindrical extensions and are adjusted by sliding one over the other, the parts being frictionally clamped together, as by a conical chuck device, after adjustment.
