Abstract: 1,204,637. Reduction of iron ore pellets. METALLGESELLSCHAFT A. G. April 1, 1969 [April 17, 1968], No.17093/69. Heading C7D. Reduced iron ore pellets containing 70-100% metallic iron are produced by pelletizing fine grained oxidic iron ore with 5-25% fine grained metallic iron (e.g. sponge iron or machining waste), which is added to the ore before or during the pelletizing, without the addition of carbonaceous material; firing the pellets at 700-1050‹ C. in a slightly oxidizing to slightly reducing atmosphere to give an average O/Fe mole ratio in the fired pellets of 1-1À4 and then directly reducing the pellets at 650-1250‹ C., but below the softening temperature of the charge, using solid and/or gaseous reductants. The pellets may include bentonite and may be dried before firing which may be carried out on a sintering machine or in a rotary hearth furnace (e.g. using the exhaust gases from the direct reduction). The reduction may be carried out with solid reductant in an electrically heated rotary kiln, or with gaseous reductant in a shaft furnace.

Title: Improvements in or relating to filtering and cleaning liquids
IPC: B01D29/00
Filed: 1944-09-12
Abstract: 587,721. Filters. HEYWOOD, R. B. Sept. 12, 1944, No. 17422. [Class 46] In a lubricating system of the kind in which oil is circulated by a pressure pump through a filter, an outlet leads from the inlet side of the filter to a settling tank so that in addition to the oil flow through the filter, there is a by-passed flow of oil over the surface of the filter to sweep the sludge therefrom. In the arrangement shown in Fig. 1, oil from an engine 2 is passed by a pump 1 into a storage tank 3 from which it is withdrawn by a pump 4 and fed to a filter 5. Some of the oil passes through the filter and to the engine 2, but a certain amount sweeps over and cleans the outer surface of the filter medium 6, and with the dislodged sludge is returned by a pipe 10 to a part 12 of the tank 3. The settled sludge is removed through an outlet 13. The filter comprises a cylindrical cloth medium and a helical baffle is fitted round the cloth extending from the inlet 8 to the outlet 10. The storage tank may be a tank for de-aerating the oil by means of screens, as described in Specification 559,233, [Group XXXIV], the by-pass outlet from the filter being connected to the outlet side of one or more of the screens. In a modification shown in Fig. 4, the filter is located within a sludge tank 25 and the oil is fed to the filter through an inlet 23. Some of the oil flows through the annular space surrounding the filter medium 22 and sweeps the sludge through an outlet 24 into the tank 25. The clean oil on top of the settled sludge passes out through an opening 26 and mingles with filtered oil at the outlet 27.

A hinged butt which is foldable along the outside of a smallarm is formed by or incorporates a tubular member 8 in which is a spring- urged plunger 9 provided with an operating arm 13, 14, the front end 20 of the plunger 9 having a wedge surface 21 forming (in the extended position of the butt) a small angle of 8 to 15 degrees with the longitudinal axis of the firearm and adapted to co-operate with a corresponding fixed wedge surface formed on the rear end 17 of the firing mechanism 1. The wedge surfaces are so arranged that a plane perpendicular to them and intersecting their foremost contact part 19 and parallel to the hinge axis 2 will be located behind the hinge axis 2. The wedge surfaces contact over a length about 2/ 5  and at least 1/3 of the distance of the foremost part 19 from the hinge axis 2. In the transport position, the butt is folded alongside the smallarm, the hook 14 of the operating arm 13 engaging with a fixed catch (not shown) on the smallarm. It is released therefrom by withdrawing the arm 13 which is held back against the spring 12 until the butt is in line with the smallarm and is then released to engage the wedge surfaces.

Abstract: 707,845. Valves. AKTIEBOLAGET SEPARATOR. July 11, 1952 [Sept. 6, 1951], No. 17529/52. Class 135. [Also in Group VI] A thermally responsive valve for passing liquid, e.g. milk, from a through-flow heater or sterilizer to an outlet 7 when the temperature of the liquid is at a required value but passing the liquid to an outlet 8 whence it is recirculated through the heater when the temperature is below that value consists of a valve member 5 having outer seatings for engagement with fixed seats 6, 16 and inner seatings 19, 20 for engagement by valve members 3, 10 rigid with a spindle 4 which slides with slight clearance in the valve member 5. The spindle, which is spring-loaded and actuated by a solenoid controlled by a temperature responsive device 13, 14 in the outlet 9 from the heater, has an axial bore 12 opening to radial passages 11 so that any leakage past the valve seat 6 when the valve member 5 is in the position shown drains away through the bore 12. Also, after the valve member 5 has been moved from its lower position to that shown, in response to a fall in temperature, some of the liquid in the outlet 7, which may have been insufficiently heated, drains through the bore 12. Such draining may be assisted by an air compression chamber in the outlet 7. An opening 17 serves for cleaning the valve.

Title: Improvements in connection with the manufacture of porous soft to hard rubber separators, diaphragms and the like
Filed: 1932-06-22
Abstract: In the process according to Specification 328,274, [Class 70, Indiarubber &c.], (which relates to a method of making separators, diaphragms &c. by vulcanizing a semivulcanized pulverized rubber composition in foil moulds between which are interposed lead antimony plates and heating plates), a number of the foil moulds containing the powder, are placed on one another into a casing, without the interposed plates, and then compressed until the desired thickness of separators are obtained or into boxes which are placed in a vulcanizing press.  When the composition contains very much sulphur, the foils are thicker and flat or corrugated metal sheets are interposed.  The foils may be of tinned or plated iron, the tin being removed from the face in contact with the rubber.  The foil moulds are heated to a temperature below that of vulcanization, the heat of reaction being sufficient to complete the vulcanization.  The templets referred to in the prior Specification may have ribs of different heights as desired.

Abstract: 892,269. Automatic speed-control systems. INDUSTRIAL PROCESSES Ltd. April 22, 1960 [May 25, 1959], No. 17710/59. Class 38 (4). The speed of a repulsion motor with displaceable brushgear is controlled in accordance with a first electrical quantity representative of the difference between the speed at which the motor is intended to run and the speed at which the motor runs and a second electrical quantity representative of the rate at which the speed of said motor is changing. As shown, a voltage representative of the speed of a repulsion motor 10 is derived from a tachogenerator 12 and is fed by way of a rectifier 13 to a comparator 14 which also receives a voltage representative of the speed at which the motor is to run from a reference source 15, the resulting error signal from the comparator 14 being applied to a further comparator 20. The tacho-generator 12 also feeds a differentiating circuit 17 producing a voltage which is a function of the acceleration of the motor 10 and which is also applied to the comparator 20. The output from the comparator 20 is fed over an amplifier 21 to a brush control motor 11 operating the displaceable brush gear of the motor 10 to control the latter's speed. The comparator 14 and amplifier 21 may include transistors and the voltage reference source 15 may include a gas-discharge tube.

Class 72 A method of hardening a head screw comprises moving the screw axially, past a heating probe, by rotating the screw through stationary means engaging the thread, the rotation being effected by axially movable driving means. As shown, one end of the head screw 2 is attached to an electric motor 26 mounted on a track, the remainder of the screw being supported on steadies 1 and a heating and quenching unit which comprises stationary members 8 and 11 (Fig. 2) having balls 9 and 12 which may be tightened by screw threaded pins 17. Between the stationary members a heating probe, e.g. a high frequency intensifier 5, is located, the probe entering, but not touching the thread of the head screw. The stationary members and the probe are immersed in an oil bath, refrigeration apparatus being provided to cool the oil. As the motor 26 rotates, the screw moves longitudinally through the oil bath, past the probe, and also causes the motor to move along its track.
