Abstract: 1,109,107. Brake adjusting mechanism. GIRLING Ltd. 7 Oct., 1966 [18 Oct., 1965], No. 43995/65. Heading F2E. Brake adjusting mechanism for a hydraulic brake, particularly a disc brake but also usable with a drum brake, comprises a hydraulic piston or like member 16 disposed in a bore between an inlet 8 for fluid and the actuating cylinder 3 which, in the embodiment of Figs. 1 and 2, contains pistons 4, 5 acting respectively on a directly-actuated pad 6 and, via a yoke 1, an opposed pad 7 of a disc brake, the piston 16 being connected to adjusting mechanism such as the pawl 17 and ratchet 13 for adjusting the brake when a given travel of the piston 16 is exceeded, and there being means to allow fluid to by-pass the piston 16 in response to a predetermined resistance to its movement. This resistance is provided in the embodiment of Figs. 1 and 2 by a spring 19 which normally holds a seal 18 against the piston 16 but which is overcome by hydraulic pressure in heavy braking fluid being then able to pass around cut away portions of the piston 16. A piston return spring 22 is also provided. The ratchet 13 has both externally and internally threaded portions which respectively engage piston 4 and a plunger 12 slidable in a sealed bore in piston 5 and adapted to apply the brake mechanically on operation of a lever 11. In the embodiment of Fig. 4 the brake comprises a floating calliper having a single piston with a threaded connection to the ratchet 13, the piston 16 being reciprocable axially and having a follower 17 which engages in a zig-zag groove 26 formed in the periphery of the ratchet to advance the latter. The seal is omitted, the piston 16 merely being carried along by the hydraulic fluid until the resistance provided by the spring 22 is such that fluid leaks past the piston 16 as fast as it is being supplied to the inlet 8. In a further embodiment (Figs. 5 and 6, not shown) the piston (16) fits closely in its bore but has a central passage (16A) through which fluid can pass via radial passages covered by a resilient sleeve (34) to the cylinder space, the resilient sleeve providing a one-way valve. In this construction the pawl is a bell-shaped member (33) which pivots about alternative fulcra (P1, P2) on the piston (16)

Title: Improved pipe mould and apparatus suitable for the casting of pipes from a settable cementitious mix
Inventor: LESTER DUDLEY ROGER
IPC: B28B21/22
Filed: 1963-11-11
Abstract: 1,029,788. Pipe casting. KUILS RIVER CONCRETE (PROPRIETARY) Ltd. Nov. 11, 1963, No. 44476/63. Heading B5A. In a method of making a pipe of cementitious material the pipe is first cast in a vertically disposed mould and is thereafter subjected to spinning and rolling. The mould 10, Fig. 2, is substantially cylindrical and has a core 20 which defines an annular cavity to which material is fed from a hopper 26, Fig. 1. The shell 10 has flange plates 30, 36 to which rings 34, 38 are welded. The core has an end plate 22 which, during casting, rests on a vibrating table. A stepped sleeve 40 defines a socket end of the pipe, the conical end 42 of the core facilitates filling of the mould cavity and the tapered core section 43 allows easy removal. After casting at station 14 the mould is rotated through 180 degrees, the core removed and the now horizontal mould moved, by means described later, on to two pairs of power driven rollers 64 which engage the rings 34, 38 to spin the mould. After spinning the mould is moved on to two pairs of rollers 84 and a longitudinal roller is inserted into the bore of the pipe in the mould so that, on rotation, the inside surface of the pipe is smoothed; after this rolling operation the mould is moved to a delivery station. The means for moving the mould to the spinning, rolling and delivery stations comprises a carriage having a frame 120 supported from chains 136 suspended from sprockets 138. A pair of horizontal lifting bars 112 are attached to the carriage 120 by pivoted arms 116 and each bar 112 has three projections 114 which at the appropriate instants are moved to engage the adjacent flanges of the moulds by operation of pneumatic motors which act on the pivoted arms 116. The carriage 120 is then moved upwardly by operation of a pneumatic motor 132 the piston of which is connected by a chain 144 to a sprocket 146 on the shaft 140 of a sprocket 138. The pneumatic motor 126 is then operated to move the carriage longitudinally so that the moulds are moved on to the next station and the motors 132, 134 are operated to deposit the moulds on the rollers 64, 84 and on the delivery means. In an alternative mould construction the shell is longitudinally split and is closed during operation by bolted flanges. The roller engaging rings extend from flanges which are bolted to brackets.

Abstract: 1507330 Photo-electric communications PRECITRONIC GES FUR FEINMECHANIK UND ELECTRONIC mbH 10 Nov 1975 [8 Nov 1974] 46403/75 Heading G1A A transponder receives an incident light beam, identifies the beam, modulates it and reflects it back along the incident path. The transponder may be attached to an object such as a military installation or vehicle, so that the object can be interrogated and identified from a distance. In Fig. 1 the incident beam 1 or 1' is reflected back on itself by a reflector 8, and passes through a  modulator 7, a photo-detector 2 also receives the incident light and produces an electric signal in response. The signal is demodulated at 4 to see whether the incoming beam carries suitable identifying modulation. The result of the demodulations is displayed at 5, and the modulator 7 is activated by a microphone 10 or a stored code 11  so as to reply to the interrogation by modulating the reflected light. The modulator is preferably opaque in the absence of suitably identified incident light, to prevent reflector 8 being used to locate the transponder.  A three dimensional array of transponders may be made, Fig. 2, with individual or common detectors 2 or 2', a spherical array may be approximated by adding further transponders at the top and bottom of Fig. 2. The reflectors and modulators may be coated with filters to restrict the wavelengths reflected.

Abstract: 1383977 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 18 Oct 1972 [10 Nov 1971] 47952/72 Heading H1K In a semi-conductor device, such as a shift register or delay line, utilizing the drift of an injected group 30 of minority-charge carriers through a depletion region 23À1 induced in a substrate 10À1 beneath an electrode structure 20À1, there is provided a graded-impurityconcentration region 17À1 of the same conductivity type as the substrate 10À1. The region 17À1 is graded in such a way that in the presence of the appropriate operating voltages on the substrate electrode 21À1, electrode structure 20À1, injecting electrode 15À1 and detecting electrode 16À1. The boundary of the depletion region 23À1 extends parallel to the device surface. In the Si shift register illustrated the electrode structure 20À1 comprises a plurality of interconnected A1 strips capacitively coupled to the ion implanted region 17À1 through a SiO2 layer 18À1. For P-type material a negative bias on the substrate electrode 21À1 induces the depletion region 23À1, the presence of the grounded strips 20À1 producing shallow potential wells 25 which are rapidly filled with injected charge-carriers. A subsequently injected charge-carrier group 30 will drift along the depletion region 23À1, but will tend to become progressively loss spatially localized due to space charge spreading. The group 30 is periodically reshaped by the application of a positive clock pulse to the electrode structure 20À1. Such a pulse temporarily deepens the potential walls 25, causing the drifting group 30 to be trapped and hence relocalized. Using this techique charge-carrier groups may be directed around carriers and in opposed directions. In a simplified embodiment constituting a delay line the electrode structure 20À1 is replaced by a single continuous electrode (20), Fig. 1 (not shown), overlying the whole length of the graded region (17À1), there being in this case no localized potential walls to reshape an injected pulse.

Title: Hydraulic Transmission and Control Device
IPC: B60K17/10
Filed: 1966-10-26
Abstract: 1,169,026. Valves; hydrostatic transmission. ABEX CORP. 26 Oct., 1966 [23 Nov., 1965], No. 48100/66. Headings F2D and F2V. A fluid motor 1 driving a high inertia lead 3 such as a concrete mixer, is controlled through a reversing and flow control valve device shown diagrammatically at 12, 15, Fig. 1. Operation of a control arm 33 moves the device from neutral into forward and reverse ranges F, R and within these ranges varies the size of a flow orifice 19 in the exhaust line 16, 17 in order to vary the motor speed. The speed is governed by a controller 23 responsive to pressure upstream of the orifice 19 and which supplies or releases this pressure fluid to or from a spring-biased piston 6 which regulates a variable delivery supply pump 4. A datum pressure of 200 p.s.i. is maintained upstream of orifice 19 and in neutral position this ensures the supply of make-up fluid to the motor through check valves 31, 32. In the forward range, check valve 31 connects the lines 10, 9 together across lines 35, 36 so that overrun of the load 3 is allowed for. Between neutral and forward, the device passes through a forward braking range BF. On shutting off, a gradually varying restriction 40 is interposed in the exhaust path and the exhaust from port 42 re-enters the motor through check valve 31. This dissipates the momentum of the load 3 before it is stopped in neutral and the datum pressure applied to the check valve avoids cavitation. The reverse ranges R and BR operate analogously. There is a relief 43 across the orifice 19. The valve device comprises, in one body 50, the direction controller 12, Fig. 3, and the speed controller 15, Figs. 4 and 10. The direction controller 12 includes a spool valve 58 of which the bore 59 corresponds to the line 14 in Fig. 1. Check valves 31, 32 are retained by a rod 65. Chamber 53 of the speed controller is always open to the bore 59 which communicates selectively with the inlet and motor ports 13, 41, 42. The variable orifice 40 in the forward and reverse braking ranges is formed respectively by lands 70, 71 in cooperation with ports 62. A second, rotatable spool 78 carrying the arm 33 is housed at right-angles to the spool 58 and coupled to it by an eccentric pin 85. Cross-bore 94 in cooperation with a port 79 provides the variable orifice 19 in conjunction with a fixed orifice 95 for neutral position. Relief 43 is provided by a ball valve 90, Fig. 6 (not shown), in the spool 78. The pressure responsive controller 23 is fitted to the body as shown in Fig. 4 (see also Fig. 7, not shown). A spring-loaded flow control valve 60 at each end of the spool 58 has a disc co-operating with a dimple 131 in the body. Movement of the spool away from neutral is thereby opposed by the restricted flow to prevent power surges.
