Title: Improvements in, or relating to, electric circuit-breakers
IPC: H01H71/74
Filed: 1935-06-28
Abstract: 456,379. Automatic circuit-breakers. CRABTREE, G. E., Endwood, Little Aston Park, Sutton Coldfield, ELLIOTT, W. T., The Vicarage, Grosvenor Mount, Leeds, BADHAM, E., 34, Buchanan Road, Walsall, and THORNTON, R. W., 3, King Edward Street, Oxford, [Representatives of CRABTREE, J. A.] June 28, 1935, No. 18492. [Class 38 (v)] The contact-holding and resetting mechanism, including a trip - catch or equivalent member, and a thermal release device are embodied in separate units and an adjustable calibrating device or unit is interposed between the mechanism and /or release units, in such a manner that it is adapted to transmit movement from the trip-bar or like member of the release unit to the trip-catch or like member of the mechanism unit. In the arrangement shown, the locking and resetting mechanism, which is of the kind described in Specification 415,129, is mounted in a double-sided and open-ended frame a in such a manner that the tail of the trip-catch a<1> lies along the open bottom of the frame. The releases, comprising a thermal element acting on a trip-bar c, and an electromagnetic element acting on a trip-bar d, are assembled as a self-contained unit in a housing b which is mounted below the frame a. The calibrating unit comprises a tappet or leverlike member g which is pivoted in a U-shaped hanger h trunnioned to the frame a. One of the trunnions h<2> is in the form of a screw, in order that the angular position of the hanger may be adjusted and the hanger then clamped in position on the frame. The side of the lever g which is presented to the trip-bars c, d is formed with a series of steps or notches of progressively-increasing depths or, as shown, with a recess g<1> having an inclined roof, so that transverse adjustment of the lever relatively to the trip-bar c varies the distance through which the end of the lever must be displaced by the bar to enable it to impinge upon and transmit tripping-movement to the trip-catch a<1>. The hanger h may be provided with a pointer co-operating with an amperage scale marked on the frame a in concentric relation to the screw h<2>. The lever g is preferably made of moulded insulating-material and is suspended from the hanger by a pair of metal arms g<2>. For two pole circuits the lever is formed with two recesses having inclined surfaces engaging the trip-bars of two thermal releases. The housing b may also embody a leakage-current protective device acting on a third trip-bar f which is arranged to act directly on the tripcatch a<1>. Specification 415,393 also is referred to.

Abstract: 1486129 Automatic control systems MECHTRON INTERNATIONAL CORP 6 May 1975 [10 May 1974] 18977/75 Heading G3N In a control system for drying apparatus, a heater, used for drying moving material e.g. sand on a conveyer, is controlled according to the measured mass flow-rate and moisture content of the material. As shown, signals dependent upon the flow-rate and moisture content, from sensors 12, 14 respectively and measured before drying, are multiplied together and the result compensated according to measured ambient temperature. The result forms a desired heating capacity for dryer 16, and is compared with the actual fuel flow to the dryer. Any difference is used to control relays, to energize drive motor 36 for the fuel valve 30 in a forward or reverse direction. In another embodiment, not shown), two aggregates are used, each with a moisture sensor and the control is modified by the temperature of the dried mixture.

Filed: 1946-06-25
Abstract: 624,567. Resistance measurements. SHOTTER, G. F., and NORTHMET POWER CO. June 25, 1946, No. 19042. [Class 37] The Figure shows a device for measuring the resistance of a conduit 1, comprising a casing containing an ammeter 6 in series with a switch 14 and a variable resistance 5, one terminal of which is connected by a short lead 7 to a clip 8 engaging one end of the conduit. A long lead 9 connects the switch to the earthed end 2 of the conduit, through the secondary of a mains energized transformer 11 supplying a predetermined test current to the circuit, the value of which is marked on the scale of the ammeter. In operation the switch is closed and the variable resistance is adjusted until the ammeter indicates the predetermined current. The conduit resistance may be read from the scale of the variable resistance which is calibrated in conjunction with leads 7 and 9 and the transformer 11 to read the conduit resistance directly when the variable resistance is adjusted as above. A lower current value may be marked on the ammeter scale, when a second calibrated resistance scale is provided for use therewith. The instrument may be D.C. fed, and lead 7 may be replaced by a spring prod operating the switch 14 when pressed into contact with the conduit.

Title: Improvements in the manufacture and production of artificial compositions and articles made therefrom
IPC: C08J9/04
Filed: 1928-06-30
Abstract: 321,423. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 30, 1928. Casein is rendered porous by the incorporation therein by mixing under pressure, and if necessary heat, of a pore-producing substance, and then releasing the pressure. Suitable poreproducing agents are carbonates, bicarbonates, carbamates, bisulphides, hydrosulphides, or liquids of low boiling-point, which are not considerable solvents for the casein. The material added may have a hardening or softening action. According to an example, alkali-soluble casein, chrome yellow, and ammonium bicarbonate, are wetted with water, and mixed and pressed at 70‹ C. through an extrusion press. On issuing, the mass swells considerably, and may then be hardened with formaldehyde, or the formaldehyde may be added to the mixing water. The mass may be coloured as described in Specification 242,274, [Class 70, Indiarubber &c.].

An indirectly heated thermistor has a thin layer of insulation 14<SP>1</SP> around the thermistor bead 10<SP>1</SP> and has attached to a limited area of the surface of this layer a small bead 21 of electrically insulating material of high thermal conductivity within which are embedded two parallel heating wires 15<SP>1</SP>, 16<SP>1</SP>. By placing the heating wires in a small bead the thermal capacity between the heater and thermistor is kept low and the neck between the two beads ensures that heat from both heaters follows the same course to the thermistor to ensure that the same response is obtained for identical inputs to the two heaters. With glass insulation 14<SP>1</SP> the small bead 21 may also be of glassthe insulated thermistor may be lowered on to a molten bead of glass and pulled up to leave an " icicle " of glass depending from the main bead-this " pills-up " into the form shown when further heated and may then be lowered on to the jigged heater wires to embed them. It is suggested that the layer 14<SP>1</SP> may instead be of ceramics or plastics material.

Abstract: 1473516 Carbon black; acetylene black PRODUITS CHIMIQUES UGINE KUHLMANN 3 May 1974 [15 May 1973] 19535/74 Heading C1A Carbon black having the properties of an acetylene black is prepared from at least one hydrocarbon from the general classes of olefins, aromatics unsaturated cyclics and polycyclics, by preheating to above their critical temperatures and then by incomplete combustion with oxygen under reduced pressure at a temperature of at least 1700C. The product is a black having a filter index higher than 80, a carbon content of 99% and a particle size of 150-200 . The oxygen used in the incomplete combustion may also be preheated. Preferred hydrocarbons are ethylene, benzene, toluene, oxylene or a petroleum cut having a high proportion of unsaturated polycyclics. The process is carried out in a vertical furnace of the type shown in Fig. 2. The hydrocarbon is preheated in preheater (4) to a temperature as high as possible having regard to its thermal stability (the temperature being measured at (12)), and then introduced to the furnace via the burner (2). The oyxgen is introduced to the burner via line 11, after optionally being preheated in preheater 5. The carbon black produced forms agglomerates which are disintegrated by means of a grinder (6). A lowering of the pressure within the furnace by a ventilator (3) carries the aerosol of carbon black and the cracking gases to a set of cyclones (7) where the black is separated and conveyed to a hopper (15).
