Title: Improvements in locking devices for lift gates or doors
IPC: B66B13/20
Filed: 1925-03-10
Abstract: 242,144. Fothergill, J. March 10, 1925. Lift cages and doors, locking. - A locking device for the door or gate of a lift adapted to prevent tampering with the lock when the door or gate is open, comprises two switches in series with the lift controlling circuit and mechanism adapted to open one switch if the second switch is closed by an inserted implement'. The gate a carries a bolt s having a slot e adapted to receive a roller r on a two-armed lever l mounted on a pivot f and having an arm n carrying one contact of a switch o. A second lever l<2> mounted on the pivot f carries one contact of a second switch u. When the gate is closed the bolt passes into the lock casing so that the roller r engages the slot in the bolt and the nose s<1> of the bolt raises the pivoted lever l<2> and closes the switch u. As both switches are now closed the lift can be operated. When the gate is open, as shown, the roller r obstructs the bolt opening h in the locking casing so that if an implement is inserted in the opening to raise the lever l<2> and so close the switch u, the implement will raise the roller rand lever l and so by opening the switch o will prevent the lift from being operated. Specifications 6967/12 and 3062/15 are referred to.

Title: Improvements relating to transistor amplifiers
IPC: H03F1/30
Filed: 1954-03-08
Abstract: 786,854. Transistor temperature stabilized amplifiers. GENERAL ELECTRIC CO. March 8, 1954 [March 9, 1953], No. 6703/54. Class 40 (6). In a cascaded amplifier feeding an output load, a component of the output current of each stage is passed through the final load so that the current flowing in the load is relatively insensitive to temperature variations. In a grounded base, grounded emitter amplifier, Fig. 1, the increment of current, due to temperature change, appearing in the collector circuit 19 is fed, in part only, over resistor 33 to the base 23 to oppose the increment of current due to temperature change which would otherwise occur in the collector 25 feeding the load 31. The relation between the resistors 29, 33 controls the fraction of the increment of current fed forward and a formula is derived giving the optimum value for stabilization. In a modification, Fig. 3, the resistor 44 is arranged in the common lead to the collectors 19, 25. Alternatively, by choice of transistors having suitable characteristics a simple circuit employing grounded emitter stages, Fig. 5 (not shown), may be employed. A multi-stage amplifier of this type may be used, Fig. 7 (not shown).

Title: Utilization of iron-coke fines
Inventor: BECKER JOSEPH
IPC: C22B1/22
Filed: 1955-03-08
Abstract: In the treatment of iron oxide bearing materials in which such materials are mixed with a small portion of the total coal charge which is destined for high temperature coking and use as the total coke with said material for metallurgical purposes, the mixture and the larger portion of straight coal being separately coked in coke chambers of the slot type with high temperature coking at a rate of one inch per hour by heat applied indirectly laterally inwardly of the masses in the chambers, the iron-coke fines from the iron-coke product produced from the coked small portion are screened out and recycled to another coal charge destined for said chambers, whilst the remainder of said iron-coke product and the product of coking said straight coal are used conjointly for metallurgical purposes. The screens may have 1/8 -\ba3/4 inch square openings.  The chamber heating of said small portion is continued longer than the heating of the larger portion by coking said mixture for a period of 2-6 hours longer than that normally required at a rate of one inch per hour for satisfactorily coking coal alone.  The recycled fines may be crushed and mixed with (a) the total coal charge destined to be coked, (b) a small portion of a total coal charge which has been mixed with other iron oxide bearing materials and is destined to be coked separately in said chambers, or (c) a larger straight coal portion of a total coal charge destined to be coked in said chambers separately from a smaller portion of said total coal charge which is mixed with other iron oxide bearing materials before being coked in said chambers.  To prevent the charge containing more inert non-coking material than can be bound by the coal, 1-15 per cent by weight of pitch or tar may be added to the charge.  Specifications 749,802 and 775,747 are referred to.

Filed: 1929-03-08
Abstract: 334,874. Marks, Sir G. C., (Du Pont de Nemours & Co., E., I.). March 8, 1929. Lakes.-Oil and water-insoluble lakes of azodyestuffs are prepared by incorporating a metallic compound in a mixture of an azo dye of acidic character and a resin soap in aqueous medium, to form a precipitate of the metallic compounds of resinate and azo-dye in which the resinate is present in amounts of from about 5-60 per cent of the finished product. Or the metallic resinate is incorporated with the precipitated pigment of the azo-dye of acidic character prior to the development of the pigment and the latter is then developed by boiling. The azo-dye may be soluble, slightly soluble or substantially insoluble in water and usually contains sulphonic acid and/or carboxylic acid groups. The resin soap may be incorporated wholly or in part, prior to or during the coupling of the azo-dye components and in the case of a water soluble dye substantially simultaneous precipitation of the metallic compounds of resinate and azo-dye may take place. The metallic salt is preferably an alkaline earth metal compound such as calcium chloride, barium chloride, or mixture thereof, or a salt or salts of magnesium, lead or copper may be used. In examples (1) 2-naphthylamine-1-sulphonic acid is diazotized and coupled with #- naphthol, and to the alkaline solution is added a solution of sodium resinate and the mixture precipitated with barium chloride or calcium chloride and boiled; an example also illustrates the precipitation with calcium chloride at the boil; (2) a solution of sodium resinate is added to 2 : 3-oxynaphthoic acid and a diazotized solution of p-toluidine-m-sulplionic acid run in; the mixture is precipitated with calcium chloride and boiled; (3) 2-naphthylamine-1-sulphonic acid is diazotized and coupled with 2 : 3-oxynaphthoic acid m-nitranilide, a solution of sodium resinate added, and the mixture precipitated with barium chloride ' and boiled; (4) diazotized alpha-naphthylamine is added to a solution of 1-naphthol-5-sulphonic and sodium resinate, the mixture precipitated with calcium chloride, and boiled.
