Title: Improvements in and relating to centrifugally produced structures of plastic material partly or wholly deviating from longitudinally straight form
IPC: B28B1/20
Filed: 1927-04-25
Abstract: 286,498. Watson, C. W. April 25, 1927. Centrifugal machines; moulding pipes.-Curved hollow structures such as pipe bends are moulded centrifugally two at a time from cementitious material with or without embedded reinforcement by means of the machine shown, which rotates about an axis through the ends A. The material is fed at each end A into the hollow part 5 of the core C, which communicates by perforations 19 with the mould surrounding the whole of the core. The material passes into the mould after striking a conical deflector 23, the perforations being varied in size and disposition according to the distance from the axis of rotation to ensure differential feeding into the mould. Building up of the structure proceeds retrogressively from the end D, and it is finally supplemented by radial filling. Each part of the core C is made up of longitudinal segments 2, 5, Figs. 9 and 10, the two parts being united by means of overlapping arcs 8, 11, which are gripped between rings 14, 15. Cover strips 43 prevent the entry of the material into the mould between the segments 2 of the imperforate part of the core. In a machine for moulding a tapering structure, the core need not be segmented. The ends of the segments are held in position by rings E, F, and the rings F of the two cores are held between heads on cross-bars 30, which are connected together by a tie-bar 34. The deflector 23 carries lugs 22 by which it grips plates 20, Fig. 9, carried by each segment 5 of the core. The mould ends B, D and core ends S, S<1> are contoured as desired, and as shown are designed to produce faucet and spigot ends respectively. The reinforcement R consists of helical wire united with longitudinal members z and held in position by peripheral or longitudinal projections 41 on the core segments. Spacing blocks 44 may be used where projections are inconvenient. For contouring the surface of the structure, an elastic ring p is provided at the feed end, that shown being arranged to contour an internal chamber. The ring p is held by stops q, and it has a folding loop by which it may be readily removed after the end S has been withdrawn. Holes y are provided for the escape of air.

Title: Improvements relating to pulse modulated transmission systems
IPC: H03K7/00
Filed: 1942-08-07
Abstract: 583,799. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and SCULLY, C. T. Aug. 7, 1942, No. 11098. [Class 40 (v)] In a duration-modulated pulse transmitter, means are provided for shortening the duration of the pulses before transmission so that the shortest pulse is always reduced to a desired minimum and all other pulses are shortened by correspondingly equal times. As shown in Fig. 7, modulated pulses, of the form shown in Fig. 1 with their front edges F recurring at equal time intervals, are fed as synchronizing pulses to a saw-tooth oscillator 3, the output of which passes to an amplitude limiter 4 as in Specification 582,324 to produce pulses of constant duration as shown in Fig. 2. After amplification at 5, the constant duration pulses are combined differentially at 6 with the original pulses to produce a train of shorter pulses shown in Fig. 3, the shortest pulse A of Fig. 1 being reduced to a desired minimum duration LO. Unnecessary expenditure of power during periods of low percentage modulation is thus avoided. An alternative method consists in combining the original modulated pulses with these same pulses delayed by a suitable interval, and utilizing the shortened pulses represented by the high-amplitude portions of the combination. The delay may be introduced by a network interposed in one of two parallel-connected paths (Fig. 8, not shown), or by a network connected in shunt to the main path and arranged to give a delayed reflected pulse (Fig. 9, not shown).

Title: Pressure control device for the hydraulic change device of a change-under-load gearbox more particularly in motor vehicles
IPC: F16H61/02
Filed: 1975-03-19
Abstract: 1479791 Change-speed control ZAHNRADFABRIK FRIEDRICHSHAFEN AG 19 March 1975 11410/75 Heading F2D In a control system for effecting automatic ratio changes in an epicyclic transmission of a vehicle in response to a combination of load dependent and vehicle speed dependent pressures, a further pressure derived from the load dependent pressure governs the magnitude of pressure applied to ratio-establishing clutches and brakes. The system is similar to those described in Specifications 1,274,490 and 1,467,458, comprising a valve 10 controlling the pressure of fluid delivered by an engine driven pump P to a pipe 205 and selector valve 30. When the latter is positioned for forward drive, i.e. at position A for automatic operation in all of three ratios, at position 2 for automatic operation in the first two ratios only, or at position 1 to hold first ratio, the fluid is directed through a conduit 207 to react on the valve 10 and through a conduit 208 from which it passes to a clutch K1 employed for all forward ratios and to 1-2 and 2-3 shift valves 70, 90 controlling another clutch K2 and brakes B1, B1F and B2, and subject on their end faces 73, 93 to the vehicle dependent speed from a controller R transmitted through a conduit 240. This pressure is opposed by the load dependent pressure transmitted to surfaces 70A, 90A through conduits 220, 221 leading from a valve 40 of which a plunger 42 is actuated through a cam N by the accelerator linkage so that, in response to accelerator depression, a spring 43 is compressed to cause the valve, which is supplied with fluid from the pipe 205, to deliver the load dependent pressure to a conduit 48 and past the displaced plunger 42 to the conduits 220, 221. The pressure in 48 acts on a plunger 342 of a modulator valve 340 whereby that valve delivers a derived pressure through a conduit 222. This pressure, which initially rises more steeply than the load dependent pressure in 48 and then levels off, acts on a surface 18A of the valve 10 and is also supplied to damper chambers 123, 163 which, as in the two prior Specifications referred to, control the rate of increase of pressure in the clutch K2 and brake BIF. A modified arrangement has two spool valves in place of the single valve 340, one valve determining the steeply rising pressure characteristic and the other becoming effective at a predetermined pressure to cause the levelling off.
