Abstract: 390,959. Mine-roof supports. RICHARDS, F., 14, Brynheulog Street, Port Talbot, Glamorgan. April 25, 1932, No. 11801. [Class 20 (ii).] Flanged bars of H- or like section forming the composite parts of steel arches, props, and the like, for use in mines &c. are adjustably jointed together by means of slidably mounted fishplates 2, formed so as partly to embrace the edges of both flanges of the members 1 to be connected, the adjacent ends of these members being spaced apart if required, with or without an intervening filling 5 of timber ; the frictional resistance necessary to maintain the joint is obtained by means of clamping bands 4, which by themselves, or in conjunction with the fishplates, encircle the joint. The clamps 4 may be of U-form, and fit into notches 3 formed in the flanges of the fishplates. Alternatively, lugs may be provided on both edges of the fishplates, clamping bolts being inserted therethrough. A pair of fishplates may form the end-members at one or both extremities of an arch or the like, as for example, in the construction shown in Fig. 7, where fishplates 9, secured at one of their ends to a main flanged member 1, form an adjustable foot at one end of the arch. Instead of an insertion 5 of timber or the like between adjacent ends of connected members, a roller or fulcrum bar may be provided to facilitate taking down the structure. For the same purpose, in another modification, the ends of the members 1 abut directly, one or both ends being tapered. Various combinations of parts are described, in which the fishplates or the flanged members are either straight or curved.

IPC: B01D3/42
Filed: 1969-03-10
Abstract: 1,255,541. Automatic control systems. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. March 10, 1969 [March 12, 1968], No.12381/69. Heading G3R. A method for the automatic control of a number of process variables by a digital computer in response to measured values of the variables is characterized by the provision of at least one alternative programme for use in the event of a disturbance in the operation of the process equipment or a part thereof. Change-over to the alternative programme may be automatic, and it may be designed to provide reduced normal product and/or a gradual termination of the process. The invention is described in relation to two alternative processes, a distillation system, Fig.1 (not shown) and a catalytic reforming process for hydrocarbons, Fig.2 (not shown). In the first of these pressure, fluid-flow and liquid level are measured at various points and if any of them are outside upper and lower limits the alternative programme is used to adjust e.g. the feed, condenser coolant flow, the flow in re-circulatory loops &c. until the variable is restored to within the limits. In certain cases a second and different correcting action is made if the first is insufficient. The system includes means for keeping the ratio between certain quantities constant so that corrective action is applied to both. The second system uses similar control arrangements of these same variables, and in addition the temperature in reactor vessels is kept constant by adjustment of heater fuel supply, and if the temperature drops below a minimum value the set point of a feed control system is lowered. The normal operation of these systems is not described in detail, and neither is the computer.

Filed: 1970-03-16
Abstract: 1309696 Colour television display tubes MATSUSHITA ELECTRONICS CORP 16 March 1970 [19 March 1969 (2)] 12578/70 Heading H1D A shadow mask support mechanism for a colour TV tube includes three or four mask supporters at least one of the supporters comprising a bi-metal member 17 secured to the frame 2, its free end connected to a leaf spring 8 the other end of which extends towards a pin provided on the tube side wall. The thermal deflection at the metal platen-spring connection is such that the expansion at the pin side is smaller than on the other side this preventing local twisting of the spring and non-uniform movement of the mask towards the screen. Uniform movement toward the screen compensates for colour purity errors due to thermal expansion. The bimetal piece 17 welding line L may intersect the welding line l in the range five to fourty degrees, preferably about fifteen degrees. Two bimetal parts (27), (37), (Fig. 5, not shown), may be used in parallel, of respectively different expansion coefficients by including different materials for each other, or may be of different thicknesses or shapes. Also the part (37) on the pin side may be replaced by a single layer metal plate. A lower expansion U-shaped metal plate (47a), (Fig. 6, not shown), may be combined with a higher expansion plate attached to the leg remote from the pin or a bimetal plate (57), (Fig. 7, not shown), may include a further metal piece (57c) welded at the side near the pin to mechanically reduce the expansion.

Abstract: 1,261,220. Drop hammers. BRITISH STEEL PILING CO. Ltd. 10 March, 1970 [11 March, 1969], No. 12814/69. Heading B3H. A drop hammer has its ram connected to an hydraulic piston 20 and cylinder assembly which has a conduit 28 between the upper and lower spaces controlled by a spool valve 32 which is closed by fluid pressure in the upper space resulting in a pressure rise in the lower space to raise the piston. The spool has an opening 40 and is normally spring biased 34 against a stop ring 38 to align the opening with an annular duct 30 connected to the passage 28 the supply of fluid is controlled by a valve (46), Fig. 1 (not shown), which may be controlled by a pressure line from an opening 58 in the cylinder. The piston falls under gravity when the lower space is connected to the reservoir although the fall may be spring (81), assisted. The piston is cushioned by a sleeve 64 which enters a restricted part 68 of the cylinder to trap fluid. The connection between the ram and the piston-rod has a rubber bushing to absorb shock. In an alternative embodiment, Fig. 3, the  piston 82 rests on a pile dolly (not shown), and the cylinder 84 slides on the piston and is attached to the hammer weight. The valve spool 32 between the spaces operates similarly to that of the first embodiment. The valve 46 to supply fluid to the spaces can be controlled by a solenoid (100), Fig. 5 (not shown), and an adjustable timer (102). An impact detector (104) serves to trigger the timer. In a further embodiment, Fig. 6, the spool valve is mounted in a conduit 88 externally of the cylinder.

Abstract: 1497440 Testing pipe joints E D HAUK 27 March 1975 [29 March 1974] 12846/75 Heading G1S A threaded drill pipe joint 202, Fig. 1, to be tested is enclosed by split half casings such as 23, having semi-annular collars 24, one of the casings being supported by a fixed jaw 13 and the other being supported by a jaw 14 which may be pivoted by means of pneumatic cylinders 15. The jaws are clamped around the joint and a test pressure is produced within an inner chamber formed around the joint by split half short rubber packers 21a shorter than the joint length, or alternatively when a regular pipe coupling is to be tested by longer split half packers 21 as in Figs.8, 9 (not shown), and as in United States Patent No. 3371521, the pressure being applied through a hose 98 from a pump 101, through a fitting 59, see also Fig.2, to a pressure annulus 212, the pressure being monitored on a gauge 103, and the casing halves being locked by pivoted hooks 17 operated by pneumatic cylinders 19. The apparatus described thus, for except for the use of alternative short packers, is identical to that shown and described in Fig.1 of the above referred to United States Patent. The packers suitable for the type of joint to be tested are bolted to the half casings and prevented from being axially extruded from the casing by outer rings such as 71a, Figs.2 and 6 which engage and expand segmented inner rings 72a and force teeth 214 into a gripping position on the pipe coupling. The inner and outer rings 71a, 72a, Figs.3, 6 are held loosely together by bolts 236 passing through holes 234 and loosely into threads 238, and the rings are fastened to the casings 23 by bolts 240 loosely threaded into holes 244. Elastomeric elements 232 seated in holes 230 are compressed when the casings are closed and radially preload the rings 71a thereby forcing inwardly the two segments of each ring 71a which in turn forces the inner rings inwardly against the pipe joint to provide the necessary sealing pressure.
