Title: Improvements in apparatus for agglomerating and roasting minerals
IPC: F27B21/06
Filed: 1927-12-21
Abstract: 283,133. ProgrÞs Minier et MÚtallurgique Soc. Anon., and Samsonow, A. de. Jan. 4, 1927, [Convention date]. Discharging.-Ore roasting or agglomerating apparatus of the open pan type is provided with discharging means so constructed and arranged as to minimize the formation of dust and to prevent its escape into the building. As shown in Fig. 4, the pan comprises a cylindrical wall e which, on completion of the heat treatment, is raised to permit the passage of a ram b which pushes the treated material off the grate c<1> into a receiver g or on to a conveyer. The pan may be rectangular in plan, in which case only the front and back walls are removable. Fig. 5 shows a modification in which the ram b acts upon the wall e which is pushed into position above a discharge aperture through which the treated material falls on to a conveyer d. Two further constructions are described in which the grate c<1> is adapted to act as the discharging member, the grate, in one case, being of the endless chain type and, in the other, comprising a grid slidable horizontally into and out of position. In the latter arrangement, the treated material is dumped into the suction chamber f from which it is removed through a door at the lower end.

Title: Process and device for the low temperature distillation of fuels
IPC: C10B7/06
Filed: 1928-11-26
Abstract: 322,332. HÚreng, A. J. A. Nov. 26, 1928. Coking processes; retorts.- Solid fuel is distilled at low temperature by being dried and passed through a heating chamber on a pervious endless chain grate, the coke. residue being either burned to generate steam or recovered as coke, or gasified in a water gas generator. The fuel from a drier S is received on a chain grate G and is moved through a distillation chamber D heated to 600-650‹ C. by burners O. The semicoke passes into a combustion chamber C in which it is burned with air from conduits A, to raise steam in boiler V. The distillates pass by conduits H to a tar main B from which the tars are returned by pipe L to the distillation chamber to bind the small particles of fuel. The cleaned gas is returned to the burners O from which excess gas passes under a screen and is burned in the combustion chamber C. In a modification, hot gases are passed through the charge and powdered coke may be recovered. In Fig. 4, the gases evolved are passed through a superheater R and then through the fuel which is pressed while soft by an endless chain K, the lump cobe being cooled by distillation gases from a pipe I before it is recovered. In Fig. 5, the hot coke is collected in a hopper Y from which it is fed on to an endless chain grate, G1.Water gas is generated by blowing air from a fan W through the fuel which is brought to a red heat and is then subjected to a steam blast from covered spaces F, the water gas being passed through a heat exchanger N in which the steam is superheated. A superheating boiler V1 produces steam for the process. Blowers Z1, Z2 supply the distillation gas and water gas to a holder. The coke remaining is burnt with air from the blower W.

IPC: F04D15/00
Filed: 1956-11-15
Abstract: 853,027. Electric correspondence control systems. WEIR Ltd., G. & J. Feb. 17, 1958 [Nov. 15, 1956], No. 35021/56. Class 40 (1). [Also in Group XXVI] Overheating of a centrifugal pump is avoided by controlling the electrical or steam power supply to the pump driving means by a relay controlled by the difference in temperature between the fluids entering and leaving the pump, as sensed by thermistors connected into a bridge circuit. As shown, a steam turbine 4 drives a centrifugal pump 6 via gearing 5, and an oil pump 7 feeding a cylinder 14 containing a spring-loaded piston 15 connected by a bellcrank 16, 17, 18 to a spring-loaded stop valve 20 controlling the steam supply to the turbine 4, the oil pressure pipe 12 also being connected to a discharge pipe 21 via a governor-controlled valve 23 responsive to the speed of the pump 6, or via a solenoid-operated valve 22 controlled by a bridge circuit 3 including thermistors 1, 2 in the suction and discharge systems of the pump. If the temperature difference sensed by the thermistors exceed a predetermined value, relay 22 is operated, the oil pressure in pipe 12 falls, piston 15 is released to engage lever 16, which via levers 17, 18 operates valve 20 to cut-off the steam supply to the turbine 4. Similar action occurs when relay 23 is operated at a predetermined speed of the pump 6. Specification 814,401 is referred to.

IPC: B65B13/02
Filed: 1953-12-16
Abstract: 749,561. Tensioning bands. GERRARD INDUSTRIES, Ltd. Dec. 6, 1964 [Dec. 16, 1953], No. 35078/53. Class 45. [Also in Group XVII] In a packaging machine in which a band 5 is fed from a reel and passed around the package by the rotation of a drum 31 in one direction, and the band is tensioned, after the free end of the bans is clamped by a gripper 13, by reverse rotation of the drum, a single control shifts the gripper into and out of the clamping position and presets a gear control so that on operation of a further control the drum driven by the gear will feed the band when the gripper is unclamped and tension the band when the gripper is clamped. A pedal 1 is connected to an arm 7 of a bell-crank 7, 17, the arm 7 being formed as a handle. The bell-crank is fixed to one end of a shaft 8 passing through a gear-box 10 and having an operating arm 11 for the gripper fixed at the other end. The arm 17 of the bell-crank has a pin-and-slot connection with one end of a lever 20, pivoted at 20a, and slidably connected at the other end to a rod 22. The rod 22 is pivoted to a spring-returned lever 23 carrying a pedal 24. The upper end 26 of the rod 22 slides within a groove 27 in a rocking beam 28, a spring 37 connected to the lever 20 causing the end 26 of the rod 22 to occupy either of the extreme end positions of the groove 27. The rocking beam is pivoted on the shaft 8 and is connected to a reverse gear housed in the gearbox so that clockwise movement of the beam causes reverse or tensioning rotation of the drum, whilst anti-clockwise movement causes forward or feeding rotation. Depression of the pedal 1 slides the gripper 13 to coact with a stationary gripper 16 to hold the band, and shifts the end 26 of the rod 22 to the right-hand end of the beam. Depression of the pedal 24 then causes clockwise rotation of the beam and reverse rotation of the drum. The handle 7 is raised to release the clamp 13 and move the end 26 of the rod 22 to the left-hand end of the beam, so that when the pedal 24 is depressed the drum rotates to feed the band.

Title: Improvements in or relating to drilling and other machine tools
IPC: B23Q35/02
Filed: 1945-12-31
Abstract: 616,541. Drilling machines; work-tables. BULLARD CO. Dec. 31, 1945, No. 35231. Convention date, Jan. 6. [Class 83 (iii)] A selective automatic positioning device for the work-table of a drilling or other machine tool comprises a member movable along a straight path, means adapted to be continuously effective to exert a constant force at any point along said path for moving said member in one direction therealong, a number of auxiliary means each adapted to exert a constant force greater than the previous' means at any point for moving the member in the opposite direction, separate independent means for limiting the movement of each of said auxiliary means, a number of presettable means, one for each of said auxiliary means, and control means for rendering any one of said auxiliary means operative and all others inoperative. In an application of the invention to the work-table of a radial drilling machine, a base-piece 33, Fig. 4, carried by the machine frame 20, has secured thereto a housing 43 bored to provide a number of cylinders 49. A further cylinder 42 accommodates a piston 45 connected by a rod 40 and nut 41 to a member 38 rigidly secured to a slide 34. Fluid pressure is fed through a pipe-line 46 to the right-hand side of the piston 45, tending to move it and the slide 34 to the left. The slide straddles the housing 43 and moves on guideways 37. The remaining cylinders in the housing 43, fourteen in the example described, each carries a floating piston 50, Fig. 4, and is supplied with pressure fluid from openings 57 in the left-hand cylinder ends. A stop-block 51 over the right-hand ends of the cylinders limits movement of the floating pistons, but bores in the block corresponding to the cylinders, but of smaller diameter, allow the entry of screwed gauging rods 56 carried in the block 38. The effective diameter of the floating pistons is twice that of the piston 45 and the net effect of this when pressure is supplied selectively to one of the floating pistons and to the cylinder 42 is to drive the floating piston to the right-hand end of its cylinder against the stop-block 51 carrying with it the corresponding screwed gauging rod and thus positioning the slide in some predetermined location. Fixed and movable vernier scales 95 and 96 facilitate the adjustment of the slide 35. A rotary valve operated by a hand wheel 67 enables any one of the fourteen cylinders 49 to be supplied with fluid pressure. A similar arrangement for a slide 35, Fig. 2, mounted on the slide 34 and movable at right angles thereto, is provided. A compound slide arrangement with selective automatic positioning in two directions at right angles is thus provided.

[Class 135.] An initial charge of lubricating oil is supplied to the cylinders of an internal-combustion engine when the latter is in a cold condition by a device controlled in its action by the temperature of the main or of an auxiliary supply of oil, or, by the temperature of the cooling water; when the engine warms up the oil supply is cut off. As shown, a valve member 15 is carried by the free end of a bi-metallic strip 13 supported in a member 4 having oil inlet and outlet passages 20, 19, respectively. The member 4 is secured to the oil sump casing 6 so that the tubular part 7 surrounding the strip 13 is immersed in oil. The valve 15 has squared portions 17, 18, guided in the passages 19, 20. The outlet passage 19, which is adjustably controlled by a screw 21, leads directly to the engine cylinder or to the engine induction pipe. When the engine is cold oil passes through the outlet 19 to the engine cylinders. As the oil warms the valve closes gradually and when a predetermined temperature of oil is obtained the outlet passage 19 is completely shut off.

A mower adapted to be mounted on the three point linkage of a tractor has three mowing bars 1-3 (Fig. 1, not shown) the outer two of which are substantially parallel to the middle bar and pivotable relative to the middle bar about substantially vertical axis between operative and inoperative positions. The three mowing bars have reciprocable knives driven from the tractor p.t.o. shaft. Rocker arms 68, 72 pivotally mounted on the frame have lugs 69, 73 engaging an elliptical groove in a disc 62 which is rotated by a shaft 58 connected to the p.t.o. shaft of the tractor. The two arms effect drive of the knives of the mowing bars 1 and 3 by way of connecting rods 116, connecting members 118 pivotable about axis 110, coupling rods 105 and rockable arms 96 (Figs. 1 and 5, not shown). The rocker arm 68 includes a housing 70 (Figs. 3 and 4, not shown) which engages a projection 43 on an arm 55 which is rockable about a shaft 38 to reciprocate the knife of mowing bar 2. The mowing bars 1, 3 are connected to frame 5 by means of parallel bars 80 which are pivotable about axes 79 to the position shown in broken lines, and each mowing bar pivots about a vertical shaft 74 and is locked either in its operative or inoperative position by a spring urged bolt 128 engaging holes 129 in a quadrant 125 (Fig. 1, not shown). When the mowing bar 1 is moved to its inoperative position, i.e. through 90 degrees, reciprocation of the knife bar is stopped since the coupling rod 105 will be at approximately 90 degrees to connecting rod 116 (Fig. 7, not shown). Upon raising the mower an upper link 122 (Fig. 4, not shown) which is connected to the tractor will cause the mowing bars 1, 3 to be raised by means of cables 120. Pivoting of the mowing bar 2 will also take place about axie 27, and the projection 43 will be disengaged from the housing 71. During operation of the mower the tractor is driven backwards.
