Title: Improved cutting machine
IPC: B23Q5/48
Filed: 1960-08-10
Abstract: 916,849. Severing by grinding; sawing. BRADSHAW, A. R. Aug. 9, 1961 [Aug. 10, 1960], No. 27666/60. Classes 60 and 145. A section-cutting machine having means for advancing a specimen 29 across the cutting edge of a rotating cutter 9 comprises a " slip " drive between a motor 6 and the feed mechanism, the drive being transmitted through an epicyclic gear. An input shaft 14, Fig. 2, drives through gears 15, 17, coupled through planet wheels 19, 20, and gears 16, 21, an output shaft 22 and through a worm gear 26, 27, the feed screw 4. The planet-carrying wheel 16 is rotatable on the shaft 14 to which the sun wheel 15 is fixed. The sun wheel 17 is also fixed to a short braking shaft 18 coaxial with the input shaft 14. The planet wheels 19, 20 mesh respectively with sun wheels 15, 17 and with each other. A brake drum fixed to the shaft 18 has an adjustably spring-loaded pad 25 bearing on its peripheral surface whereby the torque transmitted to the output shaft may be varied by a screw 31. Under normal cutting conditions the shaft 18 is held, but if an increase in torque is required to drive the output shaft 22 of the gear-box 5 the brake pad 23 is adjusted to prevent rotation of the shaft 18. If rotation of the shaft 18 occurs the planet carrier 16 ceases to rotate so that the drive is not transmitted to the feed-screw 4, with a corresponding reduction in the torque required to rotate the feed-screw, until conditions are reached when the drive is transferred back to the shaft 22; the greater the resistance to rotation of the shaft 18 the more the cutting effort is allowed to build up between the specimen and cutter before the feed-screw drive is interrupted. The cutter 9 may be an abrasive disc of a thickness between 0.005 to 0.020 inch, running at about 10,000 r.p.m., or a circular saw. If a slitting disc is used one of the rubberbonded silicon carbide type is preferred. The specimen holder 3, feed-screw 4, gear-box 5 and drive motor 6 are mounted on a table 10 which is adjustable towards and away from the cutting chamber 2 by a micrometer screw (not shown). Nozzles 30 may project into the chamber 2 to direct water to the face of the disc.

Title: Improvements in or relating to the resistance heating of steel
IPC: H05B3/00
Filed: 1956-09-11
Abstract: 808,680. Heating metal bodies by passage of current. BOCHUMER VEREIN FUR GUSSSTAHLFABRIKATION A. G. Sept. 11, 1956 [Oct. 28, 1955], No. 27772/56. Class 39(3) Bodies of metal or alloys especially steel bars 15 are heated by passage of current therethrough from water-cooled contacts 12, 16 connected to a transformer 4. The contact 12 is carried at the end of a piston or rod 5, to a cylindrical part of which is clamped an internally ribbed sleeve contact member 1 in two parts clamped together and connected to the transformer by a lead 3. The piston 5 moves in a pressure cylinder 6 through the open stationary sleeve 1 'and forces the end contact 12 against the bar 15. Pressure in the cylinder 6 is controlled by a member 11. The opposite contact 16 is forced against a compression spring 17, and when the spring 17 is fully compressed pressure is retained in the cylinder 6 by the control 11; the contact sleeve 1 is then clamped on the piston 5 and current is switched on preferably automatically. When the steel bar 15 reaches 1000‹-1200‹C, the contact clamp 1 is opened and the pressure in the cylinder 6 is released by the control 11 to release pressure of the contacts on the bar 15. Means 18 raise and lower the bars 15. In order to heat bars of different lengths, the piston and cylinder are mounted on a movable carriage 7. The halves of the contact sleeve 1 are held together at the top by a clip 8 and are formed at their lower parts with projections 9 which are forced together or apart by a wedge 10 slidable over rollers to clamp the sleeve 1 on the piston or to release it. Replaceable frusto-conical contact members 14, 19 are placed on the contacts 12, 16.

Title: Improvements in chiming mechanism for clocks, particularly for use in timing games
IPC: G04B21/00
Filed: 1925-11-05
Abstract: 257,130. Winterhalder, J. Nov. 5, 1925. Chimes; striking-mechanism. - In chiming mechanism of the pin wheel operated type, lever mechanism is provided which co-acts with pins on the front face of the pin wheel to rotate the pin wheel in the same direction as, but independently of, the minute hand shaft carrying the pin wheel in order to adjust the chiming mechanism so that the chiming period commences at a predetermined time. The pin wheel 1 is frictionally mounted on the minute hand shaft 3 and has on its rear face three pins 2 which coact with lever 4 and hammer 5 to sound the bell 6 at twenty-minute intervals. On the front face of the pin wheel are three pins 17 co-operating with a pin 16 having a bevelled end. This pin 16 passes through a hole in a lever 8 and is attached to a spring blade 15 carried on this lever 8. The lever 8 is rotatably mounted on a barrel 9 and is returned bv a spring 11 to one stop 13 of 'two limit stops 13, 14. To adjust the chiming mechanism the lever 8 is rotated by a cord 12, the pin 16 advancing the nearest pin 17 the required amount and upon release of the cord the bevelled end of the pin 16 rides, if necessary, over the next following pin 17. During this operation a lever 18 is rocked to raise the hammer 5 away from the bell 6 to prevent striking and, through gear wheels 20, 21, 24, a pointer associated with the wheel 24 is rotated to indicate the adjustment of the chiming mechanism, the wheel 24 being frictionally mounted on the shaft 3. Instead of being mounted on the minute shaft 3 the pin wheel 1 may be mounted on any convenient arbor geared to the shaft 3.

Patent GB-358692-A (GB)
Title: Improvements in release valves of hydraulic or fluid pressure jacks
IPC: B66F3/42
Filed: 1930-09-18
Abstract: 358,692. Lifting-jacks. TANGYES, Ltd., Cornwall Works, and WILKS, B., 179, Swanshurst Lane, Moseley, both in Birming- ham. Sept. 18, 1930, No. 27911. [Class 78 (iii).] A fluid-pressure jack of the kind having an oscillatory element movable in a vertical plane, pivoted to the jack casing, and operated by the jack handle, has the handle adapted to be moved longitudinally with respect to the element so as to act on the release valve and lower the load. The handle 6 engages a socket 2 mounted on a pivot 3 and connected to the pump 5. The handle has a pin 10 engageable with a recess 9 in the socket to facilitate positioning the jack. The pin can be disengaged from the recess and by rotating the handle the pin is free to slide in a groove 11, Fig. 4, in the socket so that the handle can be pushed inwards until its nd is over the end of the release valve stem 12. By rocking the handle, the enlarged end 14 of the valve stem presses a non- return valve 13 off its seat and so permits a slow lowering of the load as the pressure fluid escapes through the port 16 past the enlarged end 14. Further movement brings the reduced part 12a of the valve stem into the port 16 and allows a quicker release of the pressure fluid.
Patent GB-762258-A (GB)
Title: Process and apparatus for separating vapors from entrained solids
IPC: C10G9/32
Filed: 1954-09-28
Abstract: Primary vapours and gases are generated from the cracking or coking of heavy hydrocarbons and are kept separate from lower quality products by momentarily contacting the feed with hot particulate solids, quenching the separated vapours, withdrawing the solids to a drying zone in which secondary vapours are evolved and maintaining a vapour seal or barrier between the dryer and the zone of separation of the primary vapours.  Oil pitchor tar feed is sprayed, with or without steam, into a transfer line reactor 11 through which hot solids, e.g. sand, metal <PICT:0762258/III/1> shot, carborundum, alumina, glass or ceramic beads, but preferably coke particles produced in the process, are propelled by steam, hydrocarbon or other gas introduced through inlets 21, 23, 25, so that temperatures of 1200-1600 DEG F. are reached under a pressure of up to 50lb. per sq. in., and the solids-gas suspension velocity is preferably at least 8ft. per sec.  Primary vapours leaving a separator 15 are quenched by water or oil, which may be the feed oil on its way to the coking line, admitted through a line 29, or cool solids may be used. Separated solids pass through a constriction 31 into a drying zone 33 in which occluded gases &c are stripped by steam or inert gas introduced through a line 35 and withdrawn through a line 85.  A differential pressure between dryer and separator of \sB 5 inches of water and preferably not greater than \sB 1 inch is maintained by means of a control valve 87 operated by a controller 89 and to obtain a clean separation of primary and secondary products steam, or ethane, propane &c., is injected at the constriction through a line 101.  The stripped solids pass through a reverse bend 39 to a heater 13 shown as of fluidized bed type, air being admitted through lines 43, 45.  Air or air and fuel introduced at a bottom inlet 49 fluidize the solids and raise their temperature of 1250 DEG -1600 DEG F. before they overflow a partition 53 for return to the transfer line reactor; occluded combustion gases may be removed by a stripping fluid admitted through a line 57.  Coke may be abstracted from the heater and dryer through outlets 65, 71.  Most or all of the coke produced may be burnt and steam generated in a coil 81.  The reactor may embody a fluidized bed and the heater a transfer line type burner.  In a modification, an outlet line from the separator has a venturi constriction within which a downwardly directed nozzle ejects hot steam, water, or combustion gases to accelerate the descent of the solids.  A valve in the nozzle supply line is controlled in dependence on the build-up of solids at the bottom of the separator.
