Abstract: 1289063 Regulating I C engines J M PEREGUDOV V A KUTOVOI and I U V RISKIN 11 March 1971 6606/71 Heading F1B To prevent runaway slipping of the wheels of a Diesel locomotive, a combined speed and load governor of the Diesel-generator set is associated with a pneumatic piston and cylinder arrangement 1, 2 communicating with an air supply via a gate valve 6 and non-return valve 7, and with atmosphere via an adjustable valve 8. During normal operation, linkage 4, 5, 15 connecting the load and speed governors enables the generator load governor to follow any deviation of the engine speed-governor actuating member from its preset position and thereby change the field current of the generator in a manner which neutralises the deviation. If the wheels begin to slip, contacts in the field current circuit are opened reducing the load on the generator and thereby causing the speed governor to reduce the fuel supply to the engine. Moreover, gate valve 6 is opened to allow air to be delivered into cylinder 1, whereby the piston 2 is raised and load governor valve 11 is thereby moved to a low-load setting. Thus, on ceasation of wheel slip and consequent closure of the field current contacts and valve 6, the controlled escape of air through filter 9 and valve 8 allows the load governor to gradually assume its initial setting, thereby avoiding reoccurrence of wheel slip due to a sudden application of the original load.

Abstract: 1296492 Automatic tension control PAUL WEBBER A G 23 Feb 1970 [28 Feb 1969] 8606/70 Heading G3R [Also in Division B8] Apparatus for regulating the tension in a web 1 comprises first and second sets of feedrollers 2,2, a tension-sensing torsion bar 7 rigidly mounted at one end and connected to levers 6 carrying a roller 4 engaging a loop 3 in the web, and control means responsive to variations in the torsional deflection of the bar 7 for correctively controlling the speed of one set of feedrollers relative to the other set, whereby the webtension is kept constant at a desired value. As shown, any movement of the levers 6 is communicated to the feeler 8 of a device 9, e.g. a potentiometer assocated with an amplifier, which produces a corresponding signal for application to a speed control device for the feed rollers. The value at which the tension is maintained constant is determined by the design and mounting of the torsion bar 7 which may be exchangeable and by the adjustment of a knob 12 which sets the disposition of the feeler 8 relative to the lever 6. In a modification, the free end of the torsion bar is connected directly to a rotary potentiometer.

Abstract: 1297134 Producing fault-free articles by sawing IMPERIAL CHEMICAL INDUSTRIES Ltd 25 March 1970 [10 April 1969] 18388/69 Heading B5L A device which causes a saw or like cutting device D to be operated to cut a substantially flat substantially rigid moving article when it senses a discontinuity or unacceptable unevenness in the under surface thereof, comprises a pair of spring urged arms, e.g. 2, pivoted at one end to a fulcrum and having at their other ends a long and thin feeler 1a and a short and thin feeler 2a respectively, and a device 16 which senses relative movement of the arms and causes the saw to operate when the feelers move relative to each other as they sense a discontinuity or unevenness. As described the device is used in cutting laminates comprising a continuous foam core, and a plurality of discrete facing sheets A, B separated by gaps C or overlapped. The laminates are fed in the direction of the arrow and the feelers 1a, 2a are urged into contact with the facing sheets by springs 19. When a gap C reaches the feelers, the feeler 2a moves into the foam, and the relative movement of the arms causes actuation of an inductive proximity limit switch or microswitch 16, which in turn operates the circular saw D. To ensure that the saw operates above a gap in the support table for the laminates, the switch 16 may be linked to the saw by a time delay or by a device which measures the distance moved by the laminate. Alternatively, the switch 16 causes a clamping device to operate which causes the saw D to move along with the laminate whilst cutting. The position of the feelers is adjustable relative to the position of the gap in the support table. The device may include two saw blades for cutting the leading and trailing edges of laminates simultaneously.

Abstract: 1297944 Moulding plastic material DUNLOP HOLDINGS Ltd 12 March 1970 [18 March 1969] 14265/69 Heading B5A [Also in Division F2]  A mould, Fig. 2, for an insulation sleeve of cellular rubber or plastics material, Fig. 1, is substantially cylindrical and has a rod-like member 21 and extension 22 to produce the bore 11 and split 13 in the sleeve. In the embodiment shown the mould is in two halves, hinged at 18, with locking devices 19 and 20. The rod which may be longer than the mould, is supported by slots in the end surfaces of the mould and the extension 22, which may be integral with the rod, is clamped between the edges 23, 24 of the mould halves when the mould is closed. Other methods of supporting the rod are by a bar across each end face of one half of the mould or by one bar on each half of the mould. The extension may alternatively be formed so that it locks with a corresponding section of each end face. The moulding operation is conveniently carried out by inserting a liquid precursor of the cellular material and then foaming the material, e.g. by the application of heat. The extension 22 is preferably positioned vertically to allow the escape of air from the mould as the foam expands and prevents the formation of undesirable voids. Another method of forming the sleeve is by hot-wire cutting; the split may be cut in a pre-bored cylinder using a split-shaped length of wire (26), the wire may be shaped to cut the bore and split simultaneously (25) or finally an outer circle of wire (28) may be added so that the sleeve can be cut completely from a non-cylindrical block (Figs. 3 and 4, not shown).

The resistive material 16 may be ruthenium dioxide or thallium oxide, the anodes 13 may be of stannic oxide, and the cathodes 15 and conductors 17 may be of Cr covered with Au. The blocks 10, 12 and 14 are preferably of glass, and the block 10 may be built up from a number of layers so that the cells assume a tapered rather than a cylindrical form (Fig. 3, not shown). Alternatively the block 10 may be replaced by a frame to provide one large cell. In this case the conductors 17 must be covered with insulating material to confine the discharges to the required positions (Fig. 4, not shown). To reduce the spacing between cells the cathodes and conductors may be "stacked" (Fig. 5, not shown) whereby a cathode of one cell overlies, but is separated by insulating material from the resistive material and conductor connected to the cathode of an adjacent cell. In further alternative embodiments (Figs. 6 and 7, not shown) conductors 17 formed on the block 14 are covered by a continuous layer of resistive material having the cathodes 15 formed on its surface, or each cathode has three conductors connected to it through resistive paths of different lengths to enable each cell to glow at any of three different intensities. The resistive layers may alternatively be connected to the anodes.
