Title: Friction materials and elements and methods of manufacturing such materials and elements
IPC: F16D69/04
Filed: 1960-03-08
Abstract: A sintered friction material comprising a predominant proportion of ferrous material is coated with a black oxide coating which may be FeO, Fe3O4, a mixture of both oxides or a mixture of one or both of them with Fe2O3. The sintered material contains at least 60% of oxidisable ferrous powder and the preferred composition is 70% iron, 20% graphite and 10% silicon carbide.  In a preferred method a powdered mixture of the components is pressed and sintered on to a steel backing and several friction articles may be formed in a single operation by stacking the articles with a graphite separator interposed between each and then hot pressing the assembly.  The sintered articles are cleaned in an alkaline solution or in trichlorethylene vapour, pickled in muriatic acid and then coated by immersion in a hot alkaline salt solution which contains alkali, metal hydroxides, alkali metal nitrites and alkali metal nitrates. After a cold and hot water rinse the articles are dipped in chromic acid and air dried.
Patent GB-385799-A (GB)
Title: Improvements in and relating to article wrapping machines
IPC: B65B57/08
Filed: 1932-03-18
Abstract: 385,799. Feeding webs. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) March 18, 1932, No. 8167. [Class 100 (i).] In wrapping-machines employing one or more continuous webs of wrapping material, the breakage of a web causes a circuit to be energized or de-energized to stop the drive of the machine. As shown, and as applied to wrappers of non-conducting material, the inner web W<1> is fed from a reel of a width equal to the length of the article to be wrapped, over rollers 14, 15, 16 and over a support plate 17. The outer web W<2>, of a width sufficient to form end folds, is fed over a roller 14a and thereafter with the web W<1> to the plate 17. At a point where the plate is gapped, the webs pass respectively under and over a copper etc. contact plate 18, the forward ends hanging over the article A on a runway 20. The article is pushed on to a lifting table 21 which lifts it to position P, drawing the webs with it, and, at this moment, a pull-off rod unwinds sufficient material from the webs for the next package, a knife severing the wrappers. During this operation, contact fingers 36, 37 press the webs against the contact plate 18. The fingers have contact tops 46, 47 insulated at 48 and connected by wires 49 to a circuit 50, 53, the other end of which is connected to the contact plate 18. If there is a break in either or both webs, the fingers touch the contact plate and close the circuit. The current induced from a transformer 52 causes a relay to break a secondary circuit 58, opening a make-and-break contact 59 and stopping the drive motor 29. When foil or other conductive webs are used, the wires 50, 53 are connected to the fingers 36, 37 and the plate 18 is of insulating material.

In 3 embodiments all electrodes are coated with fibres on one side only, the electrodes of one polarity are coated on both sides whilst those of opposite polarity are uncoated or all electrodes are coated on both sides. In Fig. 2 (not shown) the electrodes comprise supports of Ni-plated perforated steel sheet coated on both sides with sintered Ni impregnated with active material, i.e. mixed nickel and cobalt hydroxides for the nickel electrode and cadmium hydroxide for the cadmium electrode. Fibres are stuck on both sides of both electrodes.

Abstract: 682,672. Thermionic distributers. TOULON, P. M. G. March 30, 1949 [March 30, 1948], No. 8593/49. Class 40 (iii). A number of complex alternating voltages, each with peaks displaced in phase from those of the other voltages, which voltages may be used for distributing the components of a signal in a multiplex telephone circuit over a number of subscriber's lines, are produced by adding together different combinations of voltages selected from alternating voltages of more than one frequency derived from oscillators, there being a number of phasedisplaced voltages at each frequency. Signals received at E are distributed over lines such as 2, 2<1>, 2<11> in which are rectifiers 3, 3<1>, 3<11> blocked by a common battery 4. Each line is unblocked in turn, to allow passage of a signal element, by the successive voltage peaks, e.g. 23C, 23<1>C, Fig. 3, of complex waves produced in the different lines by combinations of secondary windings, e.g. 19, 21; 19<1>, 20<1>, 21<1>, 22<1>; and 19<11>, 20<11>, 2111, 22<11> of transformers 14<1>, 15<1>, 17<1>, 18<1>. The primary windings 14, 15 are fed at the same frequency K1F from an oscillator 9 with a mutual phase displacement of 90 degrees produced by an arrangement comprising valves 13, 13<1> and the primary windings 17, 18 are fed from oscillator 10 at frequency K2F with a phase displacement of 90 degrees from valves 16, 16<1>. F is the frequency of repetition of the signals. Appropriate magnitudes and phasing of the voltage peaks are produced by selecting suitable numbers of turns and directions of connection, of the secondary windings of the transformers. The oscillators are kept in synchronism with the signals by pulses fed over line 8. A single generator may control more than one distribution circuit.

Abstract: 231,877. Sharples Specialty Co., (Assignees of Sharples, P. T., and Jones, L. D.). April 2, 1921, [Convention date]. Recovering waste lubricants. - A system forpurifying the lubricating oil of an internal-combustion engine, comprises a centrifugal purifier driven from the engine. but at' a substantially uniform rate. Preferably the oil is discharged from the centrifuge in a finely-divided state and while thus divided is treated with a current of cold or heated air or gas to remove volatile impurities. In the arrangement shown, the lubricating oil of an engine 1 is circuited by a pump 4 through pipes 6, 7 to the bearings &c. and back to the reservoir 3, excess oil passing through a pressure regulator 8, a pipe 9, and back to the reservoir through pipes 10, 11 or through a pipe 13, a centrifugal 2 and pipes 16, 11 according to the position of a 3-way valve 12. When the bowl 14 of the centrifuge 2 is rotated by a shaft 18 from a motor 17, water and solid impurities are retained against the wall of the bowl, while oil passes through the opening 23 into the space 24 between the bowl and its casing 15. The finelydispersed oil is there freed from volatile impurities by a current of air or gas induced through a pipe 29 or over the motor 17 to an opening 26 bv the revolution of the bowl. Vanes 25 may be fitted to increase this gas current, the pipe 29 may be connected to a stove 30 on the exhaust pipe 31 of the engine so that the air or gas is heated, the vapours mav be condensed and collected, vanes 22 may be provided in the bowl 14 to ensure rotation of the liquid, and a conical projection 21 may be provided t'o spread the liquid as it enters the bowl. The bowl 14 is detached and emptied periodically; it may be replaced by one with an outlet for the constant discharge of the water &c. In order to drive the purifier from the engine 1 and yet at constant speed and only when the liquid is directed to the purifier, a storage battery 33 charged by a dynamo 34 driven by a countershaft. 5 of t'he engine 1 is used to operate the motor 17 and the valve 12 simultaneously, a common switch 36 being provided. The valve 12 is operated by a lever 39 moved by a solenoid 38. A timing device 37 is also provided to break the circuit automatically after a determined period of operation. In a modified arrangement, the pump 4 is placed directly beneath and is operated bv the motor 17, and oil is circuited from the reservoir to the pump and through the purifier to the reservoir so that the oil may be refined when the engine is not running. Specification 252,173 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the purification of liquids generally, by centrifuging, by treating the finely-dispersed liquids with air or gas or oxidizing or chemical reagents, or by a combination of these methods. This subject-matter does not appear in the Specification as accepted.
