Title: Improvements in Rock Drills.
Inventor: CONSTANTINESCO GOGU
IPC: B25D9/12
Filed: 1916-07-03
Abstract: 107,734. Constantinesco, G., and Haddon, W. July 3, 1916. Percussive drills.-In a percussive rock drill operated by alternating currents produced in a liquid column, the alternating currents effect also the rotation of the tool. In the drill shown, the fluid from the inlet 41 passes through a port 42, an annular passage 43, and a chamber 44 to reciprocate the piston 35 which is held between springs 39, 40, and carries the tool 32 in a spring collet 33. The fluid also reciprocates a piston 52 controlled by a spring 53, and thereby oscillates Ó spring-pressed ratchet ring 49 which engages a ratchet ring 47 splined to the piston 35 to rotate the latter intermittently. Fluid leaking past a conical needle 46 passes into and cleans the bore-hole.

Title: Improvements in or relating to apparatus for deforming thin wall tubular shells
IPC: B21D15/03
Filed: 1941-02-03
Abstract: 544,466. Treating tubes ; stamping. CLIFFORD MANUFACTURING CO. Feb. 3, 1941, No. 1431. Convention date, Jan. 25, 1940. [Classes 83 (ii) and 83 (iv)] Thin circular tubes are converted into (e.g.) hexagonal shape by fluid pressure directly applied internally by apparatus having means that initially closes the tube ends and then creates and applies sufficient pressure to deform the tube to fit the die within which the tube is clamped. The die is two-part each part made in three sections 36, 38, Fig. 5, held in seating blocks 30 mutually guided at 32 and provided with opening springs 34 and a closing eccentric 48 operated by levers 46 connected by a handle 66, Fig. 1. The ends of the tubes are expanded to enlarged hexagonal shape by the parts 57, Fig. 2, of plungers 50 having pilot portions 55 and shoulders 58 that seal the tube ends against corresponding formations in the die. The die also forms enlargements at intermediate points in the length of the tubes. The plungers are carried by rams 62 guided by splines 66 in bearings 64 and coupled to pistons 70 the cylinders for which are formed in the main pistons 74. On admission of fluid pressure at 92 the two pistons move as one under the influence of a coupling spring 82 until the shoulders 58 effect sealing arresting the pistons 70. The pistons 74 continue to advance compressing the springs 82 and causing the fluid at 80 to pass under high pressure through the bore 100 to the interior of the tube to deform it to hexagonal shape. On the return stroke non-return valves 86 permit the cylinder 80 to refill with oil or other pressure fluid.

Title: Process for the manufacture of styrene and homologues thereof
IPC: C07C1/30
Filed: 1932-01-18
Abstract: a -Chloroethylbenzene and homologues thereof (1-chloro-1-arylethanes) are heated with acids which are more difficulty volatile than hydrochloric acid, such as, for example, boric acid, palmitic acid, monochloracetic acid, benzoic acid, p-chlorobenzoic acid, a -naphthalene carboxylic acid, salicylic acid and picric acid to yield styrene and other aromatic vinyl compounds.  Polymerization of the product may be suppressed by distilling off the unsaturated hydrocarbon at the rate it is produced or by adding to the reaction mixture substances which retard polymerization such as hydroquinone, quinones such as anthraquinone or aromatic nitrocompounds such as nitronaphthalene. In examples, a -chloroethylbenzene is heated with benzoic acid or monochloracetic acid and anthraquinone to yield styrene.

Title: Method for moulding reinforced plastic material
Filed: 1956-01-17
Abstract: 816,437. Moulding resin-fibre articles. HUDSON ENGINEERING CORPORATION. Jan. 17, 1956 [Aug. 23, 1955], No. 1582/56. Class 87(2). An article, e.g. a hollow fan blade, is made by placing a layer 31 of reinforcing material, e.g. glass fibre, nylon, polyester or polytetrafluoroethylene on an outer translucent reinforced plastic mould section 20, placing a flexible core 29 having a device to partly expand the core on the layer 31, applying a further layer 32 of reinforcing material over the core, and folding the edges 31a of the layer 31 over the edges of the layer 32. Further outer mould sections 21, 22 are bolted to each other and to the section 20, and an epoxy or polyester resin is poured into the mould cavity, with the mould in a vertical position. The resin may be warmed and may contain a hardener or catalyst. A hollow shaft 34 is rotated to unwind canvas duck flaps 47, 48 about the shaft and thus cause the core 29 to partly expand and shape the reinforcement at the leading and trailing edges. Mercury or a bismuth-lead-tincadmium alloy is then filled into the core to expand it from the bottom upwardly and thus impregnate the reinforcing layers from the bottom upwardly. The mercury may be fed by a pump 43 from a supply 35 through a heat exchanger 38 to the hollow shaft 34. A valve 42 may be closed and a valve 41 opened and the mercury circulated in a closed circuit. Alternatively, the mercury may be heated by an immersion heater. For long articles, if the pressure due to the head of mercury is too great, the mould may be tilted. The temperature of the mercury may be such as to partly cure the resin near the closed end of the mould, whilst the impregnation continues towards the open end. Excess resin may escape through a pipe 44 or be absorbed in a wick 45. Metal inserts may be incorporated in the article.

Title: Process and device for the safe interruption of the flow of melt
IPC: B22D35/04
Filed: 1973-01-12
Abstract: 1421832 Gravity casting apparatus GRAVTCAST PATENTVERWERTUNGS GmbH 12 Jan 1973 [13 Jan 1972] 1749/73 Heading B3F [Also in Division B5] A gravity casting plant comprises a container 1 for the melt, a casting nozzle 18, means 5 for controlling the flow of melt from the container 1 to the nozzle, and means 26 for cooling the melt in the nozzle 18. In normal use, the cooling means 26 is in the position shown in dashed lines and a mould (not shown) is located above the nozzle 18, the flow of melt into the mould being controlled by a stopper rod 5. If it becomes necessary to replace the rod 5 or a leak develops in the apparatus, the cooling means 26 is moved into the position shown in full lines to solidify the melt in the nozzle 18 and thus permit replacement of the rod 5 without draining the melt from the apparatus. The nozzle 18 is provided with ducts 20 containing electric resistance heating wire and/or through which a coolant, e.g. air, water, liquid nitrogen, helium or carbon dioxide, may pass. The cooling means 26 is provided with a protrusion 27 which enters the nozzle 18 to assist in centering the means 26 and to enhance the cooling effect on the nozzle. When normal operation is to be resumed, the plug of solidified melt in the nozzle 18 may be mechanically removed or remelted using the heating wires in the ducts 20 or an oxygen flame.

Title: Nuclear reactor fuel element assemblies
IPC: G21C3/332
Filed: 1972-01-13
Abstract: 1382471 Fuel elements BRITISH NUCLEAR FUELS Ltd 10 Jan 1973 [13 Jan 1972 1 Aug 1972] 1758/72 and 35919/72 Heading G6C A spacer grid for a nuclear fuel assembly comprises a plurality of cojointed cylindrical ferrules 6, each housing a fuel pin (not shown), with a pair of circumferentially spaced rigid stop members 9 and a spring locating member 10 extending inside each ferrule, the line of action of the member 10 passing in opposition to and between the members 9 which lie in the same diametric plane. At least some of the ferrules 6 have their rim downstream of the coolant flow shaped to promote turbulence in the coolant as it leaves the grid. The ferrules 6 are preferably joined by welding or brazing at their lines of contact to form a polygonal array which is bounded in part by side plates 7 without the need for a peripheral band. The spring locating members 10 in pairs of adjacent ferrules 6 may be formed by double bow springs 11 having parts 12 protruding from the ferrule ends (Fig. 2) or extending wholly within the ferrules (Fig. 5, not shown). In the former case, the bow springs 11 are looped over the ferrules 6 at their lines of jointing. Midway along these lines, the ferrules 6 are formed with dimples 18 forming back stops to limit the deflection of the bow springs 11. Alternatively, double cantilever springs are attached to slotted portions of the ferrules to act towards and between a pair of co-planar fixed stops. Enhancement of the heat transfer between coolant flowing over the fuel pins, spaced by the ferrules, and the fuel is achieved by forming turbulence promoting tabs 13 on the ferrule rims on the outgoing side of the grid and the effect of these tabs 13 is augmented by deflectors 16 located in the ferrule rims on the upstream side of the grid, effective to deflect coolant to flow preferentially through the ferrules 6 rather than through the gaps between them. The deflectors 16, at an angle of between 45 and 90 degrees to the ferrule axis, also serve as a means of adjusting the overall pressure drop in coolant passing through the grid by selecting the appropriate deflector angle. The turbulence tabs 13 are formed by making axial cuts in the ferrule rim and bending the ferrule between adjacent pairs of cuts alternatively inwardly and outwardly.

IPC: B41L11/08
Filed: 1955-01-20
Abstract: 782,584. Printing-machines. BLOCK & ANDERSON, Ltd. Nov. 28, 1955 [Jan. 20, 1955], No. 1796/55. Class 100(2) A rotary printing or duplicat- Ing machine having a printing drum carrying the matter to be printed, and an impression roller mounted on a shaft adjustable by presure control means for applying printing pressure and driven by a driving shaft to drive the drum by frictional contact, is characterized by means for locking the pressure control means in the "pressure on" position and means for allowing release of the locking means within a small angular interval of each drum revolution such that no printed impression can then be taken from the drum. As shown, the printing drum 1 of a rotary duplicating machine has a clip 2 for sectoring a hectographic master sheet 3. The impression roller 4 is carried by bearings 5 slidable in guides 6 and supported by transverse rail 8 engaged by screws 9 carried in arms 10. The arms 10, keyed to a shaft 11, are rocked by a cam surface 14a, on a lever 14, engaging a roller 13 on the arms into "impression on" and "impression off" positions. The lever 14, pivoted on a stud 15, is adjustable around a sector 16 and held in four positions defined by notches by a spring catch 17; the positions correspond to the roller 4 in "impression off" position and three positions of "impression on." The roller 4 is driven through pulleys 24, 23, 21, 19, 18 and belts 20, 25 by a shaft 26, the pulleys 19, 21 being carried by an adjustable lever 27. When the drum 1 is at rest the clip 2 is approximately in the position A. The lever 14 is then raised, such that the drum 1 is driven by frictional engagement with the roller 4. Sheets are fed over a table 29 by feed rollers 30, 31, such that the leading edge of the sheet and that of the master sheet coincide when the clip reaches a position B. The lever 14 is locked in "on" position by a latch 32 held against a stop 35 by a spring 36. The latch 32 is tripped away from the lever 14 in each revolution of the drum by a pin 38 after the master sheet and copy sheet have passed the roller 4. Sheets are damped by a pad 54 (Fig. 2, not shown), pressed downwardly by springs, the pad being rocked downwardly into engagement with each sheet by a cam actuated lever. Sheets are advanced by an intermittently rotated wheel 30 (Fig. 2, not shown), actuated by a cam on the shaft of the drum 1. In a modification, the roller 4 is driven through a clutch which, is actuated by the lever 14, Fig. 1, which may also actuate a switch in the circuit of an electric motor driving the roller 4. Specification 733,262 is referred to.
