Title: Improvements in and relating to Wall and Floor Panels.
Inventor: JOICE JOHN KAEN
IPC: E04C2/24
Filed: 1918-04-05
Abstract: 121,889. Joice, J. K. April 5, 1918. Panels and panelled work.-Wall and floor panels for portable buildings and other purposes consist of a layer of wood 2, Fig. 5, and a layer of fibrous or mill-board 3 glued or cemented to the wood 2 and bound on the edges by a metal channel member 6 which is sprung over the edges. The initial shape of the members 6 has a slight bend 11, Fig. 2, which becomes flattened by the clamping action, and the edge 10 is also locked in the board 3. A hollow panel may be formed of two millboards 21, Fig. 10, or a millboard and an ordinary board, separated by and glued to wooden strips 18, with a metal binding similar to that described above but in which the spring action is obtained when the flanges are clamped on the panel by a press. Tongues and grooves may he formed on the metal binding, as shown in Fig. 11, to connect the panels together, or the panels may be butt jointed over studding and joists, and the joints covered by a suitable strip. The millboard may be waterproofed.

Title: Speed governor for electric motors
IPC: H02K11/00
Filed: 1958-02-24
Abstract: 853,135. Centrifugal switches. LIMIT ENGINEERING GROUP Ltd., and COLLINS, A. L. Oct. 3, 1958 [Feb. 24, 1958; June 11, 1958], Nos. 5859/58 and 18737/58. Class 38 (5). [Also in Groups XXVI and XXXV] A switch for controlling the speed of an electric motor comprises a plastic disc 40 having an upturned edge 41 and a central sleeve 42 which is a tight fit on the commutator 43. Two weights 45 and 46 are arranged to slide radially on ball bearings 51 with metal U-shaped members 47, 48 secured to the disc 40. Springs 58, 59 attached to insulating rods 56, 57 pull the weights 45, 46 inwards and cause silver contacts 54, 55 carried thereon to engage the commutator 43 through cut-away parts of the sleeve 42. Certain connections from armature 70 that would normally go to the commutator segments engaged by contacts 54, 55 are taken instead to stiff wires 63, 64 extending from the weights 45, 46, respectively, via holes 65, 66 in disc 40. The normal motor brushes are shown diagrammatically at 67 (Fig. 2) and engage the commutator in the usual manner. When the motor speed rises above a desired value one of the contacts 54, 55 first breaks engagement with its associated commutator segment and opencircuits at least part of the armature until the speed falls and contact is re-established. In a modification (Figs. 4 and 5, not shown) the rods 56, 57 are conductive and act as bridging members across metal pins half-embedded in semi-circular projections formed integrally with disc 40. The weights do not carry contacts for engagement with the commutator but are connected to respective segments via the wires 63, 64 and the broken armature windings are connected to the bridged metal pins in disc 40. The springs 58, 59 are insulated from the rods 56, 57 by sleeves thereon. Either embodiment may be mounted on the motor shaft at the end remote from the commutator, and for the first arrangement the sleeve 42 then carries a split metal ring to take the place of the commutator segments engaged by contacts 54, 55. For spark suppression the casing 40 may be moulded in a material having a relatively low electrical resistance or may have resistance paths provided therein.

Abstract: 549,449. Alloys; annealing. JOHNSON LABORATORIES, Inc. May 15, 1941, No. 6292. Convention date, June 21, 1940. [Classes 59, 72 and 82 (i)] [Also in Group XXXV] Magnetic cores for high frequency purposes are made from powder of an alloy of iron with 2-20 per cent. of tin. The material may be made from the metals or from the oxides. A mixture of finely powdered oxides may be reduced in hydrogen or other reducing atmosphere at 1100- 1500‹ F. Powdering of the iron oxide may be facilitated by heating for a short time at 2000‹ F. which renders it brittle. The reduced product may be annealed by cooling it from 1550 to 400‹ F. over at least 4 hours and then to room temperature in dry hydrogen; or it may be cooled to room temperature immediately after reduction, powdered and then annealed. Powdering may be effected by means of a brush-like appliance provided with finely pointed steel pins which are pressed through the lumps, a number of successively finer brushes or a brush with graduated pins being used. The powder is subjected to a further annealing at about 1500‹ F. which is lowered to 1100‹ F. over at least 2 hours, and further to 400‹ F over at least 3 hours, followed by further grinding. The powder may be insulated with a varnish made with chinawood oil, and the insulated powder then compressed with a binder such as a synthetic resin, preferably not over 4 per cent. of the weight of the finished core, at a pressure up to 35 tons per square inch.

Title: Improvements in or relating to a process for preparing a hydrocarbon reactant for conversion
IPC: C10G61/02
Filed: 1957-02-26
Abstract: An hydrocarbon feed containing oxygen as a contaminant is stripped prior to hydroforming or hydrofining to remove the oxygen, using as stripping gas tail gas from the subsequent conversion process or other hydrocarbon conversion process.  In one embodiment a naphtha to be hydroformed containing 0.1 to 2% by weight of oxygen is stripped at 100-200 DEG  F. under sufficient pressure to maintain the naphtha liquid, e.g. 10-60 p.s.i.g., using 100-1000 SCF per barrel of naphtha of the tail gas from the subsequent hydroforming process.  The temperature may be maintained by keeping the tail gas at 10-50 DEG F. above the stripping operation.  A kerosine to be blended with gas oil for hydrofining may be stripped with tail gas from a hydroforming operation.  The oxygen content should be so reduced as to prevent the formation of resinous material on subsequent heating of the feed prior to conversion, the amount of oxygen preferably being reduced below 0.1%.ALSO:In a hydrocarbon conversion process, particularly hydroforming a naphtha feed, wherein a hydrocarbon reactant containing oxygen as a contaminant is converted in the presence of a catalyst to a normally liquid and a normally gaseous product, the reactant is stripped with a portion of the gaseous product or tail gas from another hydrocarbon conversion process to remove oxygen prior to the conversion.  In a preferred embodiment a naphtha feed to be hydroformed containing 0.1-2% by weight of oxygen is stripped at 100-200 DEG F. and sufficient pressure to maintain it in the liquid state, e.g. between 10 and 60 p.s.i.g., using 100 to 1000 standard cubic feet of tail gas per barrel of naphtha.  The temperature requirements may be maintained by heat supplied by the tail gas which may therefore be at 10-50 DEG  F. above the stripping operation.  The naphtha feed is then heated, e.g. by heat-exchange with reaction products to 250-350 DEG  F. before passing to a conventional furnace to be heated to 950-1150 DEG  F.  This feed is then conventionally hydroformed at 875-975 DEG  F. and 50-500 p.s.i.g. in the presence of platinum or molybdenum on alumina. The effluent is cooled and the tail gas separated for use as the stripping gas and for recycle to the hydroforming operation while the liquid products are distilled for recovering desirable petroleum fractions such as an aviation gasoline fraction and a heavier aviation base fraction.  The stripping process should be sufficient to prevent the formation of resinous compounds when the feed is heated prior to conversion, the amount of oxygen preferably being reduced to below 0.1%.  The tail gas after use in the stripping operation and thereby mixed with oxygen may be used as a fuel elsewhere in the hydroforming operation.
