Title: Improvements in or relating to the manufacture of composite panels, such as doors
IPC: E06B3/70
Filed: 1944-07-26
Abstract: 587,177. Composite panels and doors. JI-TE AKTIEBOLAG. July 26, 1944, Nos. 14281 and 14282. Convention dates, July 7, 1943, and March 2, 1944. [Classes 20 (iii) and 20 (iv)] [Also in Group XXIII] In .making composite panels such as doors having ribs arranged between facing panels the ribs are selected accordingly as they twist to the right or to the left and are assembled so that the net influence of the torsional forces of the individual ribs will be negligible. As shown, a door comprises ribs 14, previously matched, spaced vertically in a frame formed by the uprights 10 and cross-pieces 12 and covered by the facing panels 16 and 18, the ribs being arranged with adjacent ribs of opposing twist. The twist is measured by the amount of force required to restore the rib to the "plane" state or by the amount of deviation from the "plane" state of the ribs. Blocks 22 may be inserted between the ribs at the centre of the door. To reduce further the torsional influences the ribs and blocks may be provided with one or more longitudinally extending slots in a plane perpendicular to the plane of the door. These slots may be used to join the ribs to the frame by wedges entering them and similar slots cut in the frame, or the ribs themselves may be formed by several lengths united together by wedges. Those ribs which show no tendency to twist may be used separately or together with twisted bars to form the skeleton. The bars as well as being twisted may be curved in their longitudinal direction in which case alternate bars of oppositely curved form may be used.

Title: A lubricating composition and process of production thereof
IPC: C10M177/00
Filed: 1953-05-21
Abstract: A lubricating composition is prepared by adding to a colloidal graphite suspension in water a naphthalenic or paraffinic mineral oil, or a Turkey Red oil, having a viscosity not less than 820 seconds Redwood I at 1400 DEG F., kneading the mixture so that the colloidal graphite is transferred from the water to the oil, and removing the water which separates.  A stabilizing agent to prevent separation; flocculation and sedimentation may be added either during the kneading or after the removal of water, and in the latter case kneading may be continued until a homogeneous mass is obtained.  The stabilizing agent may be a steam-refined cylinder oil or a vegetable oil and the vegetable oil may have been polymerized, for example by exposure to silent electric discharge.  A polymerized linseed oil such as stand oil is mentioned as a suitable stabilizer.  The mineral oil employed in the preparation of the lubricating composition may be a cylinder oil and is preferably unfiltered.  The Turkey Red oil employed may contain 2-3 per cent of a metal soap such as calcium stearate. Specifications 27312/07, 6463/10 and 4155/12 [all in Class 91] are referred to.

Abstract: 1401422 Stress limiting devices BROWN BROS & CO Ltd 10 Aug 1972 [12 May 1971] 14584/71 Heading B8B [Also in Division F2] To limit stress in a towing cable 4 for a ship, a pulley 3 carrying the cable is secured to the piston-rod 2 of an hydraulic piston-cylinder shock absorber. On build-up by the load on the cable of a predetermined pressure in the cylinder, an adjustable pressure relief valve 6 opens to exhaust liquid, e.g. to a reservoir 8, allowing the piston-rod to move into the cylinder 1 and relieve the load on the cable. The cylinder is also in permanent communication with a gas pressurized liquid chamber which is located either in a separate bottle attached by line to the cylinder (not shown) or (as shown) in the hollow piston-rod. There may be a pump (not shown) to pump liquid from the reservoir 8 back into the cylinder so as to reset the shock absorber. Alternatively the cylinder may be connected to an external supply of liquid under pressure. The pressure at which the relief valve 6 will open is set by adjusting a valve 7. The cylinder 1 is fast with a bolster 10 which is fast with the ship's frame and has eyes 11 for passage of the cable 4.

Abstract: 1343673 Preventing cracking in inorganic foams SENTRALINSTITUTT FOR INDUSTRIELL FORSKNING 14 May 1971 [15 May 1970] 14988/71 Heading B5A [Also in Division C1] Cracking is prevented during the solidification of inorganic-foam articles, by providing in the articles channels through which a cooling gas is passed. The channels are formed after the block has achieved dimensional stability, cooling gas is passed through the channels and over the block surfaces until the respective temperatures are the same, and the cooling is then continued at a rate proportional to the heat conductivity of the foam material, until temperature equilibrium throughout the block has occurred. An expanding agent and pellets, granules or powder of inorganic material of clay, glass powder or slag are heated to foam on a conveyer or in a conveyer-mounted mould, to form building or insulating blocks. A foamed block is cooled at a high rate in a production kiln until dimensionally stable but not solidified in its interior. Channels are drilled parallel to the block major faces using a set of tubular, water-cooled drills around which the foam solidifies. In a cooling kiln, air (at 720‹ C. for clay) is passed through the channels and around the block. In an alternative method, the channels are drilled after the foamed block is solid throughout. The finished block can be split.
