Title: Improvements in or relating to winding gear for bucket loading shovels and the like
IPC: E02F9/20
Filed: 1936-06-25
Abstract: 476,510. Winches. BOYDELL & CO., Ltd., E., and BOYDELL, E. June 25, 1936, No. 17626. [Class 78 (v)] In winding-gear for bucket-loading shovels, &c., including any gear having a self-applied brake with a release lever for controlling the lowering of the bucket, the brake-release mechanism is connected to the control lever through a trip release and catch mechanism and means are provided, operated by the slackening of the cable on the bucket striking the ground, to actuate the trip release. Fig. 1 shows a drum, having driving and brake side flanges b, loosely mounted on a shaft e carried eccentrically in bearings. The shaft e has rigidly mounted on it depending levers j<1>, one of which is linked at i to the extension arm h of a weighted lever g, which tends to bring the drum against stationary brake blocks a. The manual lever k, spring-retracted at u, has a link l pivoted to its lower extension, and an L-shaped slot m near its outer end engages a pin on the other lever j <1>. Springs n keep the link l up so that the pin is in the vertical portion of the slot m, and operation of the lever k in one direction brings the drum against the blocks a and in the other direction against friction-drive wheels f. The cable s passes from the drum to the bucket round a pulley t, and on the cable rests a roller r carried by an arm q extending from a spindle p. On the outer end of the spindle p is fixed a hammer arm o located over an extension of the link l. On momentary slackening of the cable when the bucket strikes the ground the arm o drops to hit the link l and bring the pin on lever j<1> out of the vertical into the horizontal portion of the slot m, when the weighted lever g is able to act on the shaft e to bring the flanges b against the blocks a. The brake is thus momentarily applied and further slackening of the cable prevented. A pull on lever k will then bring the drum flanges b against the wheels f and on release the vertical portion of slot m again engages the pin. Specification 437,190, is referred to.

Title: Improved Means for Conveying Ropes Underneath Sunken Wrecks.
Inventor: THOMSON THOMAS
IPC: B63C7/16
Filed: 1918-10-29
Abstract: 130,855. Thomson, T. Oct. 29, 1918. Sunken ships, raising.- Apparatus for passing a rope beneath a sunken ship, intended for use in conjunction with the needle or catcher described in Specification 112,570, comprises a framework or setter 1 which is lowered to the sea-bed, and is positioned at the proper distance from the wreck by a rod 10 extended by hydraulic action from a cylinder 11. Mounted on the setter is a hydraulic cylinder 2 carrying a piston-rod 6 at the end of which is a detachable head 7 carrying the rope. The cylinder 2 has two sets of ratchet teeth 3, 4 by means of which a crosshead 5<b>, reciprocated by hydraulic piston-rods 5<a>, feeds the cylinder forward or draws it backward according to which of two sets of pawls in the cross-head 5<b> is operative. When the cylinder 2 has been driven into the soil beneath the wreck to its full extent, the pressure water is admitted to the interior of the cylinder and extends the piston-rod. When the head 7 has been caught by the needle on the opposite side of the wreck, the cylinder 2 is retracted and then the piston. rod 6 is withdrawn into the cylinder. The setter is held in position during the operation by piles 9 which are forced into the ground by hydraulic cylinders 9<a>, which may be assisted by air pressure, the hydraulic cylinders operating to withdraw the piles on completion of the operation of passing the rope under the wreck. The pawls in the cross-head 5b may be of the construction shown in Fig. 13, the pawl 24 being normally held out of action by a spring 25, and forced forward to engage the ratchet teeth when pressure fluid is admitted to the cylinder 24<c>. The various valves for turning the pressure fluid on to and off from the different parts of the apparatus may be worked by a diver, or by an operator in a. diving-bell attached to the setter. The valves are preferably, however, worked by automatic apparatus and by operating valves on the salvage vessel. For taking the pressure off the cylinders 9<a> when the pile has been driven far enough, a tappet 18 on the cross-head 9<c>, during the last part of its travel, tilts a lever 19, Fig. 4, and disengages a stop 19<b> from a bell-crank lever 20<a>, which is thereupon tilted by a weight 20 and actuates the valve lever 20<b>. Similarly, weighted arms operate the requisite valves when a tappet 23, Fig. 1, moves levers 21, 22, at the ends of the stroke of the thrusting cylinders 5.

Abstract: 624,345. Gas turbine plant. BALLANTYNE, D. H. July 4, 1947, No. 17749. [Class 110(iii)] [Also in Group XXVII] A gas turbine plant is started by means of a pressure-fluid motor which may be a turbine 15 operated by the gases from a cordite cartridge 17, or by a liquid energized by those gases, and during starting the pressure fluid causes fuel, accumulated in a cylinder 23, to be delivered to the combustion chambers of the plant. To this end, gases from the cordite cartridge are applied to a piston 30 and, through a hydraulic column in a pipe 26, a piston 24 is moved to force fuel from the cylinder 23 to the injection devices 8. A non-return valve 31 prevents this fuel from being forced back through the normal fuelsupply pump 10. During normal running the cylinder 23 is kept full of fuel. When the starting turbine is operated by a pressure liquid, that liquid may be applied to the piston 24. Specification 615,689 is referred to.

Abstract: 1320272 Automatic control systems INTERNATIONAL BUSINESS MACHINES CORP 28 May 1971 [15 June 1970] 17805/71 Heading G3R A system for controlling a process 10 by a "manipulated signal" 27 derived from the difference 23 between an actual value signal from an instrument 12 and a reference value 22 includes a "response generator" 17 which changes the reference value, when an input signal 18 is changed, to a value which it is calculated will be the new actual value when the system has responded to the change in input. The steady state operation is referred to as "fine mode" and the operation which occurs following a change of input as "course mode". The response generator 17 receives the actual value signal at 16 and the manipulated signal at 19 so that its output 22 is continuously modified during the course mode until the system has stabilized in the fine mode, when 22 equals the input 18. The difference (i.e. error) signal 23 is differentiated and multiplied by a constant (for system gain) at 24, the result being added to a "derivative input" signal 21 also produced by generator 17 and the sum integrated at 26 to form the "manipulated" signal 27 controlling the process. The signal 21 is zero in the fine mode, but in course mode is initially such that a process actuator 11 is driven close to its limit, for a finite time (calculated in 17). The signal 21 is then reversed so that the manipulated signal 27 assumes its expected new value and finally reverts to zero as the system re-stabilizes. The response generator 17 may comprise a general purpose digital computer, programmed to carry out steps detailed in Figs.3-7 (not shown), or a logic circuit, Fig. 9 (not shown), using analogue signals.

Abstract: 1,175,736. Chromatographic apparatus. RESEARCH CORP. 19 April, 1967 [18 May, 1966], No. 17892/67. Headings B1L and B1X. [Also in Division G4] Fluids are subjected to chromatographic separation by passage between a pair of parallel planar extended surfaces separated by 0.00004-0.25 in. (see Fig. 1, not shown). The fluids may be either gases or liquids, and the space between the surfaces may be filled with a suitable chromatographic adsorbent. The adsorbent or surfaces may be coated with a stationary liquid phase such as dioctyl phthalate, and the surfaces preferably define a plurality of parallel channels. If desired, several surfaces may be superposed to provide several spaces in parallel (see Fig. 6, not shown) or one elongated space (see Fig. 8, not shown). In a preferred embodiment (see Figs. 3 and 4), the surfaces are circular plates 14<SP>1</SP>, 16<SP>1</SP> which are rotated, and the liquid or gas mixture to be analysed is fed by line 50 to a point in the space between the plates adjacent the axis of rotation; carrier is similarly passed by line 46. As the plates rotate, e.g. at 0.25-1 revs. per sec., the different components or reactants describe helical swathes 70, 72 and at any moment may be separately collected in chambers 60, 64 adjacent the periphery of the plates. Such apparatus may be used to separate propane and methane chromatographically. Non-rotating plates may be used to separate benzene and toluene by gas chromatography at 120C. using helium as the carrier gas.
