Title: Improvements in or relating to the bonding of graphite to surfaces and articles produced thereby
Inventor: HALL RALPH DURHAM
IPC: B05D5/08
Filed: 1950-05-31
Abstract: Graphite is bonded to a surface by applying finely-divided graphite suspended in a solution of a heat-convertible polymerized resinous bonding vehicle in such an amount to coat such a surface with a continuous semi-permanent lubricating film of graphite and heating the coated surface to effect bonding of the graphite thereto and preferably sufficiently to cure the resinous material.  The graphite may be bonded to a surface coated with a layer of low melting point metal, the surface being heated sufficiently to melt the metal and embed the graphite therein. Specified solvents are methyl ethyl ketone, methyl isobutyl ketone, acetone, ethylene dichloride and toluene.  Specified metals are indium, gallium and their alloys having a melting point below 500 DEG F.  The surface may be of iron or steel and may first be treated with a solution of metal phosphates, e.g. an acid phosphate solution.  Specified resins are alkyds, silicones and copolymers of vinyl chloride and vinyl acetate mixed with a thermosetting resinous material such as "B" stage phenol-formaldehyde resin.  In certain applications some of the graphite may be replaced with powdered mica, vermiculite or molybdenum sulphide.
Patent GB-889654-A (GB)
Title: Improvements in or relating to calcined clay products
IPC: C04B35/18
Filed: 1958-04-29
Abstract: A calcined kaolin, having a low abrasion value and suitable as a filler for paper or synthetic resins, is prepared by calcining kaolin, from which coarse impurities have been removed, and then fractionating the calcined kaolin to produce a fraction 80% by weight of which has a particle size below 2 microns. Alternatively, if the uncalcined kaolin powder contains at least 90% by weight of particles of 2 microns, calcination will produce the desired product without fractionating.  The calcined powder, before or after fractionation, may be subjected to frictional working, by wet or dry milling, to lower the clay-water viscosity and the adhesive demand, namely the proportion of casein or other adhesive which is necessary to secure good adhesion of a coating of said kaolin to paper.  The initial kaolin is normally crushed and mixed with an alkaline aqueous solution of a flocculating agent and the abrasive impurities sedimented.  The resulting cleaned kaolin may be calcined at 980 DEG to 1030 DEG C., preferably in a multi-hearth furnace, the temperatures of which rise from 302 DEG C. to a maximum of about 1000 DEG C.  The calcined aggregates, after cooling, are pulverized in a hammer mill and thereafter frictionally worked as an aqueous slurry having a pH from 7 to 10. For example, the calcined kaolin may be mixed, before or after fractionating, with sodium tripolyphosphate or tetrasodium pyrophosphate and ball milled, after which the clay is flocculated by adding alum to bring the pH to about 4.  The low abrasion, calcined kaolin may be employed as a filler for paper in association with other known fillers, such as uncalcined kaolin. The calcined powder should constitute at 15% and generally at least 50% by weight of such total filler.  Alternatively, the calcined low abrasion kaolin may be used as the sole filler, for example in cigarette paper, in amounts of 2-3% by weight.

Abstract: 713,258. Doors on aircraft. BRISTOL AEROPLANE CO., Ltd. June 11, 1952 [June 11, 1951], No. 13836/51. Class 4 [Also in Group XXV] The undercarriage bay of an aircraft is closed by three pairs of doors 15, 17, 19 opening outwardly and connected mechanically to the undercarriage in such a manner that the rearmost pair 19 open and close again during extension and retraction of the undercarriage, while the doors 15, 17 remain open when the undercarriage is extended. The undercarriage comprises an oleo-leg 1 pivoted at 3 to the aircraft and at 5 to a four-wheeled bogie 6 locked in the operative position by a jack 7 which also turns the bogie anti-clockwise during the first part of the retraction process,. a damper 8 then holding the bogie in the turned position. An extensible radius rod 9, pivoted at 10 to the aircraft. locks the undercarriage in the extended position. A jack 11 serves to retract the undercarriage. A link 26 is pivoted to the oleo-leg and to a lever 23 carried by a spindle 22 which is thereby rotated anti-clockwise when the undercarriage is retracted. A lever 25, also carried by the spindle, is connected by a link 28 to the driving lever 31 of a cambox 32, the driven lever 36 of which is connected by a link 37 and lever arm 38 to a door 19. The other door 19 is operated by similar mechanism. On retraction of the undercarriage, lever 25 moves to a position 25<SP>1</SP> through a dead-centre position with respect to link 28, so that the driving lever 31, and with it the driven lever 36, reciprocates from the door-closed position through the door-open position and back to the door-closed position. The cambox (see Group XXV) is adapted to effect quick initial opening and final closing movement of the door. A door 17 is operated similarly by a lever 24 carried by the spindle 22 and connected by a link 27 to the driving lever 29 of a cambox 30, the driven lever 33 of which is connected by a link 34 and lever arm 35 to the door. Lever 24 and link 27 do not, however, pass through a dead-centre position. In a modification cambox 32 is omitted, and a driven lever on cambox 30 is arranged to move in dead-centre relation to a link operating a door 19 through a bell-crank system: Movement of the radius rod 9 is adapted to operate the doors 15.

Abstract: 959,857. Delivering sheets in counted batches. BROOKHIRST IGRANIC Ltd. April 11, 1962 [April 14, 1961], No. 13968/62. Heading B6H. A device for periodically displacing one of a number of sheets, e.g. newspapers, flowing along a conveyer 10 in overlapped relation comprises a counting and timing device 12 for indicating when a given sheet has passed under the counter, a roller 20 mounted above the conveyer for horizontal and vertical motion, springs 82 biasing the roller into engagement with the sheets, an air cylinder 18 which, in response to a signal from the counting and timing device, imparts a horizontal motion to the roller when the given sheet is positioned beneath the roller so as to displace the sheet from the line of flow, and an air cylinder 32 actuated by the horizontal movement of the roller so as to raise the roller 20 from the sheet, the cylinder 18 reversing the movement of the roller when the latter is out of contact with the sheet and the cylinder 32 being reversed so as to re-engage the sheets on the conveyer when the cylinder 18 has returned the roller to a position aligned with the conveyer. The roller 20 has a rubber surface to enable it to grip the sheets. Two pairs of rollers 24, 26 and 28, 30 engage the sheets immediately before and immediately behind the sheet displaced by the roller 20 to ensure that these sheets are not also displaced. The machine frame 75 carries bearing brackets 80 in which rods 79 are slidable. The rods 79 are connected to an arm 78, which is raised and lowered by the cylinder 32, and have collars 86 fixed thereto above the brackets 80. The shaft 34 of the roller 20 is journalled in bearing blocks 85 which are slidably mounted on the rods 79 and are urged downwards into contact with the collars 86 on the rods by the springs 82. Thus when the arm 78 is raised the roller 20 is also raised and when the arm is lowered the roller is lowered until it bears resiliently upon the sheets on the conveyer 10. The cylinder 18 is secured to the machine frame by a pin 68 and the piston rod thereof is connected to a bracket 44 horizontally slidable on pins 46, 48 carried by a stationary bracket 50 mounted on the machine frame. One end of the shaft 34 is rotatably but axially immovably mounted in a block 40 which is vertically slidable on a pin 42 secured to the bracket 44. When the cylinder 18 is operated the bracket 44 and hence the roller 20 is moved horizontally. The cylinders 18 and 32 are controlled by two solenoid-actuated four-way valves, the solenoids being energized by limit switches 15, 72, 74 actuated by the moving parts of the device.
