Abstract: 931,096. Powder metallurgy. MINNESOTA MINING & MANUFACTURING CO. June 26, 1959 [July 2, 1958; Aug. 1, 1958], No. 22054/59. Drawings to Specification. Class 82. [Also in Groups III, V, VIII, XIII, XXVI and XL (a)] A rigid honeycomb structure is formed by corrugating one or more flexible sheets of sinterable particles while in the green state and forming a structure in which nodes of the corrugations of one sheet are in contact with nodes of the same sheet or with nodes of another corrugated sheet or with a non-corrugated sheet, the sheets all being of said sinterable particles, the structure then being sintered to a rigid state with the points of contact sinter-welded together. A plasticized raw material mix containing finely divided sinterable particles, plasticizing ingredients (e.g. synthetic resins) and volatile viscosity adjusting media is formed into a thin film or sheet, preferably 0.002 to 0.05 inch thick and containing at least 80% by wt. of sinterable particles, and deposited on a metal foil, e.g. aluminium foil, preferably of the same thickness as the sheet to be corrugated, or between two such foils. The metal foil(s) serves as a carrier during the corrugating step which is performed using standard corrugating equipment after which the corrugated sheet in the green state is sawn, cut and fabricated into structures such as are illustrated in the Specification. These structures may be used as heat exchangers, catalyst supports, turbine blades or nuclear fuel elements. The sinterable particles may be metals, ceramics or mixtures of ceramics and metals. The invention may be used to form corrugated articles out of non-ductile, non-malleable, but sinterable metals such as, for example, powdered tungsten, beryllium, molybdenum, vanadium, noble metals, and intermetallic compounds such as, for example, zirconium diboride. Reference is also made to the use of chromium and alumina mixtures, to form cermets, and boron carbide. The plasticizer may be, for example, polyvinyl butyral, polyvinyl chloride, phenol - formaldehyde resin, nitrile rubber, acrylic polymers, or combinations of these with each other or with cellulose derivatives.

IPC: B60S5/04
Filed: 1952-09-08
Abstract: 714,393. Hose reels. PNEUMATIC COMPONENTS, Ltd. Sept. 7, 1953 [Sept. 8, 1952], No. 22471/52. Class 99 (2). A support 37 adapted to receive and be moved by the weight of the delivery end 33 of a hose 2 is associated with a valve 12 which effects operation of a compressed-air motor for rewinding the hose onto a reel 1 and, for example comprising a cylinder 3 in which works a piston 4 connected to a rack 5 meshing with a pinion 6 secured to the spindle of the reel. The valve 12 may be biased by a spring 13 onto an an nular seat 11 in a body part 9 and unseated by the stem 18 of an exhaust valve 17 urged away from the valve 12 by a spring 19 tc uncover an exhaust port 20. A branch 14 is connected to the cylinder inlet 15. The valve 17 is engaged by an arm 21 of a lever 22 the other arm 26 of which is engageable by an arm 28 of a bell-crank lever 29 pivoted on a plunger 27 urged away from the lever 22 by a spring 32 and provided with a bore 43 for the reception of a spring-loaded plunger 42 upon the head 41 of which bears an arm 40 of the support 37. The other arm 48 of the lever 29 is engaged by a plunger 47 connected to a port 46 in the cylinder 3. The arm 28 is swung by a spring 31 into a position whereby the arm forms an aligned extension of the plunger 27. In operation, and to retract the hose 2, the end 33 of the hose is applied to the support 37 which pivots and loads the spring 44 of the plunger 41 to urge the arm 28 against the arm 26 of the lever 22 which rocks about a pivot 23 and contacts the valve 17. Movement of the arm 21 is limited by a stop 60 on the body 9, and the valve 17 is moved to close the port 20 and open the valve 12 so that compressed air passes from the inlet 7 via the branch 14 to the cylinder to cause rewinding of the hose. Towards the end of its stroke the piston 4 uncovers the port 46 and compressed air passes to the plunger 47 which is moved to contact the arm 48 of the lever 29 to rotate and disengage the lever from the arm 26 of the lever 22 which is rocked about a pivot 23 by a spring 24 so that the valve 12 closes when the valve 17 opens the port 20 to exhaust the cylinder 3. When the end 33 of the hose 2 is lifted clear of the support 37 the spring 32 moves the plunger 27 and allows the plunger and arm 28 to become aligned. Specification 670,717 is referred to.

Title: Improvements in and relating to aircraft with rotary-wings
IPC: B64C27/54
Filed: 1946-07-30
Abstract: 614,791. Control systems for rotary winged aircraft. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and WATSON, K. July 30, 1946, No. 22639. [Class 4] In a rotary-winged aircraft having three or more rotors and controlled by varying the lift forces of all the rotors either collectively or differentially, the control system comprises a spider 79 or like member which can be tilted about any horizontal axis and has as many arms 77, 89, 90 as there are rotors (i.e. as shown, three), the ends of the arms being disposed in plan about the spider centre in a manner corresponding to the disposition of the rotors about the centre of gravity of the aircraft. Each of the spider arms is linked at 93, 91, 92 to the pitch control of the corresponding rotor in such a way that a given inclination of the spider or like member in any vertical plane displaces the resultant lift vector of all the rotors through the same horizontal distance in that plane without altering its magnitude, and the inclina. tion of the spider is controlled by a conventional control column 62 or/and individual control circuits. As shown, fore and aft movement of the control column 62 about a pivot 63 is transmitted through a rod 66, bell-crank 67 and link 75 to control the inclination of the spider about a transverse axis to cause the aircraft to pitch and to move forwardly or rearwardly. Lateral movement of the control column is transmitted by a rocking shaft 64, crank 68, link 69, bell-crank 70, rod 71, bellcrank 72 and link 76 to an arm 78 projecting laterally from the spider 79 to tilt the spider about a longitudinal axis to bank the aircraft. A further lever 82, through shaft 83, crank 85, rod 86 and bell-crank 87 raises and lowers the spider 79 bodily, to control the ascent and descent of the aircraft. The links 93, 91, 92 are connected to cranks each adapted to rotate a pulley over which passes an endless cable connected to vary the pitch of the corresponding rotor.

Filed: 1938-07-29
Abstract: 516,912. Refrigerating. ELECTROLUX, Ltd. July 29, 1938, No. 22656. Convention date, Aug. 17, 1937. [Class 29] Absorption systems.-In continuous-cycle inert gas systems in which the liquor is circulated by gas-bubble "pumps," rectification of the vapour expelled from the generator 13 is effected by indirect heat exchange with weak and strong liquor in a heat exchanger 24 at or below the absorber level, preferably after contact of the vapour with strong liquor. In the system shown in Fig. 3 with a generator of the horizontal type with a stand pipe, the generated vapour after lifting liquid in a conduit 28 passes by a pipe 18 to a vessel 19, where it bubbles through strong liquor received from a liquor reservoir 22 below the finned coil absorber 11 and then passes through the centre conduit of an inclined triple tube exchanger and on to the condenser by a pipe 25. Condensate of solution vapour drains through a pipe 33 to the vessel 19. A similar arrangement is described for a vertical type of generator. Another arrangement comprises a double helix heat exchanger 24, Fig. 5, with a drain 33 for condensate from the middle part of the coils, which in effect form a U-tube for liquor, and if desired also with a drain 43 from the warmer part of the exchanger.
