Title: Improvements in and relating to cranes
Inventor: EVANS PERCY NORMAN
IPC: B66C23/78
Filed: 1958-05-15
Abstract: 930,904. Indicating overload in jib cranes. BRITISH HOIST & CRANE CO. Ltd. Aug. 17, 1959 [May 15, 1958], No. 15634/58. Class 78 (4). A mobile crane 110, Fig. 5, is provided with a device which indicates the overturning moment about the front wheels 111. In one embodiment, the rear axle 14, 15, Fig. 1, is pivoted about a spindle 17 which lies in the longitudinal axle of the vehicle. Between the spindle 17 and the axle are resilient members 21, 22, 23, 24. As the load on the beam varies the dimensions of the resilient members alter and these changes in dimension are used as an indication of the load on the axle by being transmitted mechanically and hydraulically to a series of micro-switches which are used to operate indicator lamps which warn the crane driver of the approach of overload conditions of the crane. In a further embodiment the invention is applied to a crane having a slewable jib. The rear road wheels 112, Fig. 6, are mounted on a transverse member 122 which is pivotally mounted in cross-members 123, 124. The crossmember 124 is pivotally secured at 127 to a side member 120 and at its other end is a pressure cell 128 which responds to the force between cross-member 124 and a side member 121. A pressure gauge or indicator 130 is coupled to the cell by a pipe 131. On pressure gauge 130 are arranged a series of sets of contacts which are operated as successively increasing pressures are indicated by the gauge. Specification 843,024 is referred to.

Abstract: 728,189. Multiple fastenings. EDISON SWAN ELECTRIC CO., Ltd. June 9, 1953, No. 15843/53. Class 44. [Also in Group XI] Means for detachably securing an elongated lighting fitting in a recess in a ceiling comprises a pair of elongated members 11, 12 mounted on an end of the fitting so that they can slide longitudinally along parallel or co-linear paths and having on their inner ends pins 15, 16 positioned to move along transversely spaced paths and adapted to be engaged by a tool 27, the arrangement being such that when a turning force is applied to the tool oppositely directed forces are applied to the pins to move the members inwardly or outwardly of the fitting, the outer ends of the members being adapted to overlie bars 5, 6 extending along the longer sides of the recess. The members are mounted by means of bolts 18 on the fitting extending through slots 17 in the members and the adjacent ends of the members are cut away to provide overlapping parts 13, 14 to which the pins 15, 16 are secured. The tool 27 has a slot 27a which engages reduced diameter middle portions of the pins.

Abstract: 383,213. Vehicle draughtgear. KRUPP AKT.-GES. F., Essen, Germany. June 6, 1932, No. 15959. Convention date, Aug. 19, 1931. [Class 103 (v).] Combined draw and buffing gear described in connection with a device for applying the fluidpressure brakes of a vehicle when the buffing or draught stress exceeds a predetermined value comprises springs C, E of which the spring E is substantially stronger than the springs C, disposed between followers B freely mounted upon the draw and buffing bars A and abutting on collars a<2>, a<3>, a<4> secured to the bars. Tension rods F each secured to one of the followers D pass freely through the further follower and collar a<4> and carry nuts that engage the collar. Fixed stops B<1> are provided for the followers B. Under one-sided draught and buffing stresses only the springs C are substantially stressed since the springs E are stronger than the springs C but when the two bars are subjected to high stresses, as when the vehicles close in on one another the spring E is also stressed. This stressing of the spring E is used to open a brake valve T by the links G and mechanism shown.

Abstract: An exothermic composition for use in producing steel ingots comprises an exothermically reacting mixture containing aluminium and iron oxide, as well as 1 to 8% by weight of copper and 0 to 4% by weight of nickel, each based on the weight of aluminium present.  The ratio of iron oxide, calculated as Fe3O4, to aluminium is preferably between 3.3:1 to 4:1, a suitable range being 15-30% aluminium and 45-84% iron oxide.  The composition may also contain a slag fluxing agent, e.g. fluorspar, limestone, calcium carbonate and mixtures of fluorspar and lime.  It may be located on the surface of molten metal in a riser that is not completely filled on pouring steel into an ingot mould in a process for casting ingots from "killed" or semi-"killed" steels.

IPC: B01D45/08
Filed: 1924-07-08
Abstract: 239,005. Davies, W., and Davies, L. July 8, 1924. Spark arresters for furnace flues comprise a, baffle extending partly or wholly across the flue from the top downwards and provided with one or more passages inclined downwardly toward the outlet shaft, such passage or one of such passages having its upper end in proximity to the top of the flue to prevent accumulation of gas between the flue top and the baffle. In the construction shown in Figs. 1 and 2, the baffle 8, which is built in the flue at the junction of the flue 6 and outlet shaft 7, extends approximately halfway down the flue and is provided at the top with a downwardly-inclined passage 10. The passage 10 may extend for a short distance across the baffle, as shown, or may extend completely across in one or more parts separated by vertical ribs. The sparks passing through the passage 10 are discharged downwards into the shaft 7 and down the pipe 11 and may be removed through a door 12 on the charging platform 13. In the modifications, Figs. 4 and 5, the baffle 8 extends over the whole of the flue mouth and has a number of downwardly-inclined passages 10 which may be separated by a strengthening division 14. Instead of being arranged horizontally as shown, the passages 10 may be curved, set at an angle, or formed as vertical slots with downwardlyinclined divisions.

Title: Means intended primarily for retaining an adjustable reclining seat back in a required set inclined position
Inventor: MONK PATRICK WILLIAM CHARLES
IPC: A47C1/024
Filed: 1962-05-01
Abstract: 974,312. Hydraulic shock-absorbers. C. F. TAYLOR (METAL WORKERS) Ltd. May 1, 1963 [May 1, 1962], No. 16577/62. Heading F2S. A device for retaining a reclining seat back in a required set position comprises a cylinder 1 which is attached to a pivoted seat back (not shown) by a lug 3 and has a piston 4 slidable within it. The piston 4 is integral with a hollow piston-rod 6 provided with a forked end 10 attached to a seat arm (not shown). A ball valve 11, loaded by a spring 12 and controlled by a rod 20, normally closes a port 13 from a port 14 to prevent exchange of hydraulic fluid between spaces 15, 16, respectively, above and below the piston 4. The rod 20 is actuated by a push-button or pull-rod attached respectively to a link 22a pivoted at 26 and a pull link 24a on the fork 10, the lower end 20a of the rod 20 cooperating with an edge 21a on the link 22a so that pressure on the seat back slides the cylinder 1 over the piston 4 to compress a return spring 1a and cause fluid to pass from the space 15 to the space 16. The total fluid volume in spaces 15, 16 is kept constant by a dummy piston-rod 19 entering the space 16 as the piston-rod 6 leaves the space 15. Release of the rod 20 allows the spring 12 to close the valve 11 and lock the inclined seat back against movement in either direction. Actuation of the rod 20 to open the valve 11 when there is no pressure on the seat back allows the compression spring la to return the seat back to a vertical position. The length of the cylinder 1 can be varied by adjusting an end screw cap 2.
