Patent GB-783370-A (GB)
Title: Process and apparatus for the preparation of calcium carbide
IPC: C01B32/942
Filed: 1955-08-12
Abstract: <PICT:0783370/III/1> In the production of calcium carbide in a shaft furnace from calcareous material such as lime and carbonaceous material such as coke, the heat for the reaction being provided by the combustion of a portion of the carbonaceous material by the injection of a blast of a gas rich in oxygen into the furnace, the calcareous material is passed into the reaction zone from below the oxygen blast.  A small amount of carbonaceous material, e.g. up to 10 per cent of the total amount supplied to the furnace, may be mixed with the calcareous material and then burned by injection of oxygen or air so as to preheat the calcareous material before it reaches the reaction zone.  An endothermic gasification agent, e.g. steam or carbon dioxide, may be passed into the furnace above the oxygen blast.  As shown, fuel is supplied from hopper 1a to furnace 1 which is provided with a ring of tuyeres 3 for the supply of an oxygen-containing gas and a ring of orifices 4 for the supply of an endothermic gasification agent.  The calcareous material is supplied by an underfeed mechanism comprising a housing 15 capable of rotating about its vertical axis.  The housing contains two cylinders 111 each provided with a plunger 10.  Charging is effected by alternately filling and emptying each cylinder in turn by rotating the housing and operating the plungers.  Feed pipes 7a for air or oxygen may be provided if desired for preheating the calcareous material.  A fuel gas is evolved which passes through exit 5 while the molten carbide produced passes through exit 6.  In an alternative embodiment (Fig. 1, not shown) a single pivoted cylinder and plunger is employed.

Title: Improvements in or relating to means for detecting faults in or in connection with revolving shafts and other moving mechanical parts and/or the bearings or supports thereof
IPC: B63H23/34
Filed: 1920-08-11
Abstract: 175,311. Gardner, J. Aug. 11, 1920. Vibrations, indicating.-The condition of any of a number of shafts or other moving mechanical parts or bearings is ascertained at a central station by a common indicating-device by means of the amount and character of the noises generated in the bearings, or by visual indications caused by fluctuation of electric current in a normally-closed circuit originated by vibrations caused by breakage or other abnormal conditions or by variations of electric current caused by the altered electrical resistance of a member subjected to the rising temperature of a bearing in which lubrication is imperfect. The apparatus comprises microphones c<1> - - c<4> provided at the bearings b<1> - - b<4>, each microphone having one of its electrodes connected to its bearing. Leads d<1> - - d<4> connect one electrode to each microphone to a battery e connected through an ammeter h and a telephone j to the movable member of a switch f adapted to contact with any one of a series of contacts f<1> - - f<4> connected by leads h<1> - - h<4> to the other electrodes of the microphones. The ammeter h serves to indicate if the current is normal, so that the audible indications in the telephone may be relied on. But in the case of a microphone which has a contant resistance at a given temperature, the ammeter serves to indicate when a bearing becomes heated, due to the altered resistance of the microphone. Adjustable resistances j<1> - - j<4> or shunts may be connected in series with the microphones to secure uniformity under normal conditions. Two or more microphones may be employed at each bearing, having differing degrees of susceptibility or sensitive to disturbances of different characters, and these may be connected in series or parallel with a single switch contact, or each microphone may have its own contact.

Filed: 1920-08-11
Abstract: 149,997. Diard, F. E. M. Aug. 14, 1919. [Convention date]. Mooring.-Two adjustable and readily dissembled tripod stands having a beam passing between their heads are used to support lifting appliances or as a fixture on shore for mooring ships or boats. Fig. 1 shows the general arrangement of the apparatus, while Fig. 2 shows the method of connecting the beam and the legs to the bracket forming the head of each tripod. The bracket has a horizontal top and a vertical rear face, the top being supported by vertical flanges extending from the rear wall. Two legs are pivoted at 8, 9 to the rear face by means of bolts and nuts, and may have further bolt-and-slot connexions 20 therewith. The third leg is pivoted similarly to one of the projecting flanges 16 so as to move in a plane at right-angles to the other two legs. The bottom flanges of the I-section beam are clamped by levers 25 loosely pivoted at 27 and operated by screw-and-nut mechanism against the action of springs 30. The whole apparatus can be dissembled readily for transport by removing the various bolts and nuts. The legs may have extensions fitted thereto and may carry wheels, points, or studs at the lower ends for transporting or fixing the appliance when assembled. Suitable arrangements of chains or tie-rods may be used to fix the legs in any adjusted position. For mooring boats, the beam is arranged at right-angles to the mooring cable and the latter is secured to it.

Patent GB-355928-A (GB)
Title: Improvements in or relating to apparatus for cutting flat glass
IPC: C03B33/10
Filed: 1930-08-11
Abstract: 355,928. Cutting flat glass. PILKING- TON BROS., Ltd., 631, Tower Building, Water Street, Liverpool, and WILLIAMSONS, R. C., 28, Imperial Crescent, Doncaster. Aug. 11, 1930, No. 23990. [Class 56.] Apparatus for cutting plate or sheet glass comprises a holder for a diamond, or other form of cutter, and a feeler which brings the diamond into contact with the glass at a point inside the edge, both the holder and the feeler being mounted in a frame which is raised by, and rests on, the glass before the feeler is actuated. The glass sheet 27, Fig. 1, may travel beneath the cutting-device, or the cutter may be moved over the stationary glass. The cutting-apparatus comprises a frame 2 which is free to slide vertically between guide-wheels 4 and is pressed downwards by a weight 5, the limit of the downward movement being regulated by nuts on a screwed rod 6. The feeler consists of a wheel 8 carried by a vertically-movable rod 10 and provided with a rubber tyre 9. The diamond 11 is mounted in a holder 12 which is adjustably secured to a lever 13 pivoted at 14 on the frame 2, and the lever is connected to the rod 10 by an adjustable link 15 and a ]ever 16. A spring 21 tends to keep the feeler 8 in its lowest position and the diamond in its highest position, and a weaker spring 23 serves to take up backlash in the linkage. Wheels 25, pivoted on the frame 2, rest on the glass when a cut is made, so that the relative position of the feeder and the diamond are independent of the thickness of the glass. When the glass sheet is moved under the cutter, the edge makes contact with and raises the wheel 8 and causes the diamond 11 to descend and make contact with the glass at a point 28 slightly inside the edge. In a modified construction of feeler, shown in plan in Fig. 3, two rubber-tyred wheels 29, 29a are pivoted on the ends of a cranked shaft 30 journalled in the rod 10. With this construction, the diamond is raised from the glass as soon as one of the wheels falls off the edge of the sheet. In another modification, the rubber tyre 9, Fig. 1, may be made of rubber soft enough to be indented appreciably by the edge of the glass. In this case, the feeler wheel R will rise a little later and fall a little earlier than if the tvre were of hard substance. By adjusting the position of the diamond, the yielding of the tyre can be made to lift the diamond before it reaches the edge of the glass.
