Title: Treatment of wood
IPC: B27K3/32
Filed: 1956-06-11
Abstract: 834,818. Proofing wood against fire and biological attack. AMERICAN ZINC, LEAD & SMELTING CO. June 11, 1956 [July 20, 1955], No. 18031/56. Class 140. Wood is fireproofed by successive impregnations in either order with a soluble zinc salt and a basic material so as to form an insoluble zinc salt in situ. Solutions in water or alcohol may be used. Preferably the wood is first impregnated with an aqueous solution of zinc chloride, zinc sulphate, chromated zinc chloride, or chromated zinc sulphate and then with a solution of sodium hydroxide, sodium carbonate, ammonia, or an alkylene oxide such as ethylene oxide or less desirably styrene oxide, or with gaseous ammonia or alkylene oxide. Impregnation may be assisted by applying a vacuum before applying the solutions, followed by application of pressure during impregnation. After the first impregnation part of the impregnating solution remaining and filling the pores may be removed as by leaching with water or application of vacuum. Small amounts of bromides, phosphates, arsenites, arsenates and borates may be included in the impregnants, e.g. as additions toxic to fungi, termites and as repellants to marine borers, and magnesium chloride may also be present. After an initial impregnation with zinc chloride, the wood may be impregnated with an ammoniacal solution of zinc chloride or basic zinc chloride. Low-conductivity impregnated wood may be obtained by the use of zinc chloride and an alkylene oxide, the chlorohydrins formed being non-ionic. If desired, prior to kiln drying the soluble salts remaining may be leached out. Specifications 510,420, 834,819 and U.S.A.

Title: Improvements in automatic street lighting systems
IPC: H05B41/36
Filed: 1953-06-30
Abstract: 756,352. Photo-electric control system. MICRO BALANCING, Inc..June 30, 1953 [Aug. 21, 1952], No. 18050/53. Class 40 (3). [Also in Group XXXVII] In a street lighting control system a photocell responsive to ambient illumination operates a thermostat to control the light. As shown, the photo-cell 1 feeds an amplifier 2 which energizes the heating coil of a thermostatic element having bimetallic arms 5, 6. Arm 5 deforms and contacts a fixed stop 13 thereby rocking the element as a whole about a pivot 7 until the other arm 6 opens a switch 10 in the light circuit. If ambient temperature changes, both arms deform but remain parallel so that the element rocks about pivot 7 but switch 10 is not operated. Incident light causes A.C. fed photo-cell 1 in series with resistors 25, 27 and 29 to conduct thereby increasing the conductivity of A.C.-fed triode 20. The voltage developed across the cathode load triggers a glow discharge tube 21 in the circuit of which is heating coil 3 of the bimetallic element. The Specification states that the heat from the discharge tube itself may be used to heat this element. The bimetallic element may be helical so that if heat is applied to one end the helix rotates but changes of ambient temperature merely alter the spacing of the turns.

Title: Improvements relating to heat-insulating materials
IPC: C10C1/19
Filed: 1946-06-15
Abstract: A block or other shaped article having heat-insulating properties or for use as a filter is made by mixing pitch containing volatile matter with one or more finely-divided inert materials, and heating the mixture in an inert atmosphere to drive off the volatile constituents and cause the formation of a coke lattice binding the materials together into a coherent mass having internal voids.  The inert material may consist of sand, calcium sulphate or carbonate, or, preferably, lime sludge, and other materials in minor proportions, such for example as asbestos, may be included.  The size of the voids can be varied by varying the quality and quantity of the pitch or the temperature and rate of heating.  The pitch should constitute at least 17 per cent of the mixture unless a carbonaceous material such as sawdust be also included to prevent recarbonating. Heating should be above 600 DEG  C. but, if a carbonate be used as the filler, should not exceed 700 DEG  C., and it is continued until the production of smoke and fume ceases.  If the inert material be absorbent, it should be ground with the pitch in the wet state.  The inert atmosphere may be produced by slight surface burning of the pitch.ALSO:A block or other shaped article having heat-insulating properties or for use as a filter is made by mixing pitch containing volatile matter with one or more finely-divided inert materials, and heating the mixture in an inert atmosphere to drive off the volatile constituents and cause the formation of a coke lattice binding the materials together into a coherent mass having internal voids.

Title: Improvements in machines for removing shells or husks from nuts and the like
IPC: A23N5/01
Filed: 1921-07-04
Abstract: 186,700. Drews, J. O. July 4, 1921. Cracking nuts; conical mills.-In a machine for removing the shells and husks from nuts, seeds, &c. and of the type in which the nuts &c. pass between two relatively movable jaws having a downwardly tapering space between their opposed faces, one of the jaws or equivalent members is arranged within a central opening in the other, the jaws being so moved relatively to each other and having their opposing faces so shaped that the size of the intervening space is varied continually to cause the nuts &c. to progress therethrough and become subjected to successive impacts until the shells &c. are sufficiently cracked to fall away from the kernels &c. Within an outer cone 3 is an inner cone 4 adjustably supported on a spindle 5 to which is slidably keyed a pinion 7 rotatable by a handle 10. The lower end of the spindle 5 is formed with cams which rest on a cam-shaped boss 5a in the base 1 so that rotation of the cone 4 causes it to reciprocate as well. The outer cone 3 tapers more sharply than the inner cone 4 to produce surfaces which converge downwardly and spiral ribs are formed thereon, the ribs preferably being inclined in opposite directions. When the machine is power-operated the spindle 5 rests on an adjustable lever which is raised by a second lever actuated by a cam on the driving-shaft.

Title: Improvements in or relating to Variable Resistance Control Units and Electrical Resistance Elements Therefor
Inventor: BENDER STANLEY ORIN
IPC: H01C10/30
Filed: 1967-04-20
Abstract: 1,188,702. Variable resistors. CTS CORP. 20 April, 1967, No. 18209/67. Heading H1S. An electrical resistance element 20 for use in a variable resistance control unit comprises a carrier strip 21 of insulating material, resistance wire wound with spaced turns 22 on the carrier strip, a length of metal foil (25), (Fig. 3, not shown), interposed between the carrier strip and some of the turns adjacent one or preferably each end of the winding for short-circuiting such turns, and a terminal secured to the carrier strip and electrically connected to the resistance winding, metal being deposited on the foil strip to extend between some of the turns to improve the connection therebetween. The resistance element may be bent into an arcuate form or may be rectilinear. A rotor 30 mounting a contactor ring 31, is journalled in apertures 14, 15 in a cup-shaped insulating insert 12 and cup-shaped metal housing 11 respectively. The contactor ring 31, which has ears 32a, 32b for wiping the resistance element contacts a collector ring 26 having a terminal 27 protruding from the insert 12. The angular separation of the ears 32a, 32b is at least as large as that of the inner edges of two groups of short-circuited turns so that the assembly can be used to balance two loud-speakers. A method of making the resistance track as a continuous process comprises laying a strip of metal foil (25) on one surface of the carrier strip 21, winding wire 22 round with spaced turns, and at predetermined intervals attaching double terminals (23), (Fig. 3) by crimping. Removal of parts (23a) of the terminals produces resistance track portions having a terminal at each end. The metal foil strip is severed into three sections, the centre one of which is removed to leave two groups of short-circuited turns adjacent the terminals and metal is then deposited to improve the connection between the strip and turns.

Title: Level control device
IPC: C03B3/00
Filed: 1964-05-01
Abstract: 1,038,268. Automatic level control. H. L. PENBERTHY May 1, 1964 [May 3, 1963], No. 18235/64. Heading G3R. In a system for automatically maintaining constant the level of a conducting liquid, the level is detected by an electrode which is moved in a cyclic path passing through the surface of the liquid and has vertical and horizontal components of motion. In Fig. 2 (not shown) an electrode 22 detecting the level of molten glass 12 is mounted at the end of a tubular arm 14 loosely pivotted at 16 and continuously oscillated backwards and forwards in a horizontal direction by a wheel 26 driven by an electric motor (not shown). At the same time the presence of a shaped cam surface 20 causes arm 14 to rise and fall repeatedly. The resulting motion of electrode 22 facilitates the breaking of any glass strings which may form between the electrode and the glass surface. The relative open to closed time of the A.C. circuit completed by the electrode determines the relative on to off time of a relay 50 controlling a batch charger motor 56 which thus corrects the level in proportion to the error. Several modified cam and pivoting arrangements are described in detail and in one modification the vertical movement is produced by a hydraulic piston moved according to a predetermined time schedule.
