Title: Improvements in or relating to laminated panels
Inventor: BORUP HERBERT HJALMAR
IPC: B23K20/04
Filed: 1963-02-06
Abstract: 982,501. Laminates and laminating. KAISER ALUMINUM & CHEMICAL CORPORATION. Feb. 6, 1963, No. 4898/63. Drawings to Specification. Heading B5N. Metal-clad laminated panels, having a core of e.g. plywood, asbestos, plastics, hardboard or honeycomb structure, has the metal skins bonded to the core at elevated temperature, one skin being thinner and having a higher tensile yield strength than the other, so that when the panel cools the forces on the two sides of the core due to stresses in the metal skins can be arranged to balance and thus avoid warping of the panel. The metal skins may be of aluminium, aluminium alloys, stainless steel or other metals, either the same or different, and may be embossed, etched or striated. Mechanical force may be applied during cooling to increase the stress in the thicker skin beyond the elastic limit if the ratio of strengths of the two skins is not sufficient to compensate for the difference of their thicknesses, such force may be applied by rollers or by weights and the weight of the thicker skin itself may be thus utilized. The bonding material is preferably a phenolic formaldehyde resin film on a cellulosic carrier, bonding being effected by heat with pressure. Long roofing panels may have a plywood core with the grain of a majority of the layers running across the width of the panel. Panels may also be used for containers and boats and may be flat or curved.

Title: Improvements in and relating to the drying of tubular skins of regenerated cellulose
IPC: F26B21/00
Filed: 1933-02-18
Abstract: <PICT:0410930/IV/1> In drying tubular skins of regenerated cellulose, the skin is inflated by perforating the wall of the skin and injecting a suitable gas through the perforation.  The wet tubular skin A is drawn from the roller B by rubber covered rollers C, D, and led, supported on glass rods K, K, through an open ended drying trough E to a second pair of rubber covered rollers F, G, which deliver the dried skin to a roller H.  Hot air is supplied to the trough E through nozzles L from a supply pipe M.  The rollers F, G are some distance from the end of the trough E, and on leaving the trough E a tubular needle N attached to a flexible pipe O connected with a supply P of compressed air is inserted through the wall of the tube, so that the portion of the tube between the two sets of nip rollers is kept inflated.  The needle N is mounted in a disc Q of brass, for example, the lower surface of which has a rubber pad R to make an air-tight joint with the surface of the tube.  The compressed air may be supplied at 5--15 lbs./square inch above atmospheric pressure.  The needle N is withdrawn shortly before the rollers F, G, and the same or another one inserted near the exit of the drying through E.  The pad R may be marked with a suitable ink so that the hole may be identified.  The skin may be produced according to Specification 408,774 and led directly from the treating baths to the drying apparatus.  Specification 410,931 also is referred to.

Filed: 1918-03-22
Abstract: 123,209. Kent, W. G., (Morris, W. H. G.). March 22, 1918. Ball and float valves.- A valve device for automatically changing the discharge of liquid from one outlet to another after a predetermined interval of time, and particularly applicable for controlling the wash water used in connexion with filters, has a valve arranged between the two outlet chambers actuated by a Boat in a third chamber which is periodically filled and emptied. The apparatus is started by filling the float chamber 12 through a funnel 1211, pipe 121, threeway cock 14, and pipe, so that when a valve, 101 on the inlet is opened liquid flows through the open valve 106 to the outlet 111. The actuating spindle of the valve 101 is interconnected with the cock 14 so that, when the valve is open, the cock closes the connexion 112. 122 between the chambers 11, 12 and opens the connexion 122, 124 in order that liquid in the chamber 12 may slowly escape to drain through an apertured disk 125 and allow the valve 106 to close; water then flows through the outlet 104. On closing the valve 101, water flows from the chamber 11 through the connexion 112, 122 to the chamber 12 and re-opens the valve 106. To record the time during which the water is leaving either of the outlets, each outlet is connected by a pipe 151 to a chamber 15 containing a float 152. Each float is attached by a cord 154 to a, pulley 153 connected to a notched disk so arranged that, when liquid is flowing and the float chamber filled, the float turns the disk to raise a bar 20 out of the notch and move a pen 211 over a clockworkdriven recorder 22.

Abstract: 641,388. Snap action switches. CORY CORPORATION. Feb. 20, 1948, No. 5117. Convention date, Feb. 27, 1947. [Class 38(v)] [Also in Groups I, VI, XI and XVIII] In a coffee making machine in which infusion is initiated by depressing a handle 36 and is terminated when a predetermined weight of infusion collects in a receptacle 30, the handle on being depressed opens a valve 84 supplying water under pressure to a boiler 88, and switches on a pair of heating elements contained respectively in the boiler and in a scale pan 32 for the receptacle. The handle is mounted on a bar 212 pivoted to a slidable rod 204. Fig. 14. which bears upon the valve spindle, and to a link 218 to form a toggle which is held in the over-centre position, when the handle is depressed, by the valve spring. The switches are closed by a member 300 mounted on the rod 204 bearing against spring contacts 256 and 258 controlling the boiler and scale pan heating elements respectively. The receptacle 30 is balanced against a counterweight 186 on a scale beam fulcrummed at 172. On descent of the filled receptacle a roller carried by the scale beam strikes a stud mounted on the bar 212 to trip the toggle, when the valve spring closes the valve and disengages the member 300 from the spring contacts. A stud 306 carried by the scale beam closes a spring contact 264 when the receptacle descends, to maintain the scale pan heating elements in circuit until the receptacle is lifted from the pan. The downward movement of the receptacle is accelerated to enhance the snap action by providing a pair of permanent magnets 232, 234 adapted to approach each other, and by so arranging the counterweight and scale pan that, on descent of the latter, their moment arms are respectively decreased and increased.

Title: A fuel injection system for an internal combustion engine
IPC: F02M51/00
Filed: 1928-02-20
Abstract: 311,477. French, L. O. Feb. 20, 1928. Valve gear.-A fuel-injection valve 21 on the cylinder head is actuated by an electromagnet. 23 controlled by a switch 28, means being provided for varying the amount of valve lift by varying the amount of energization of the electromagnet. The switch 28 comprises a cam 33 driven by the engine and actuating a contact 30, 31, a condenser 44 being provided to prevent arcing. The amount of energization of the magnet, and therefore the amount of valve lift and of fuel injected, is varied by means of a resistance 34, the action of which is adjusted by an arm 36 actuated by an accelerator pedal 38. If the cam 33 is non-adjustable, the period of contact at 30, 31 decreases with increase of engine speed, but this may be compensated for by cutting out some of the resistance. Fig. 2 shows a construction of switch in which the cam 45 has a tapering profile, and is adjusted axially by a speed governor 55 so as to maintain a constant period of switch contact for all speeds. Hand adjustment of the cam is also effected by a lever 58, and the timing of the commence. ment of injection is varied by angular adjust ment of the switch casing 29 by means of a hand lever 29<1>. The governor sleeve 64 also adjusts a carbon-pile resistance 47 through a lever 65. The lever 58 also adjusts the load or the governor spring 56. A rotary distributor 75 having a brush 69 wiping over contacts 71, con trols the supply of current to the various engine cylinders. In another construction of switch the cam is adjusted angularly to vary the timing of injection, as well as axially, and the resistance is varied by an arm oscillated through toothed gearing. The valve may be constructed as described in Specification 297,237.

Title: Naturally or artificially granulated, activated or unactivated anhydrous sodium peroxide
IPC: C01B15/043
Filed: 1934-02-20
Abstract: Anhydrous sodium peroxide is prepared in a granular agglomerated or porous form for use in the regeneration of air vitiated by breathing. One method of preparation consists in slowly oxidizing sodium in a current of dried air (say at 100 DEG  C.), and then after the sodium has melted, increasing the temperature say to 200--300 DEG  C., without reaching the fusion point of the peroxide.  The peroxide is obtained in irregular porous pieces.  The sodium may be peroxidized in an aluminium boat in an electrical resistance furnace. Alternatively, commercial sodium peroxide powder is agglomerated by compression say in a mechanical tableting press, to form a compressed body of diminished apparent density.  The evolution of oxygen may be facilitated by mixing with the peroxide, preferably in the course of manufacture or agglomeration by compression, one or more catalysts such as vanadium, chromium, cobalt, nickel, manganese, rare earths, hydrates and higher oxides of potassium, hydrates of sodium, or the mixed peroxide K2NaO5.  These catalysts may be introduced by sprinkling a dry metallic salt on the surface of the product, by peroxidizing the metallic sodium in a boat of nickel, tombac, red copper, brass or the alloy known under the Registered Trade Mark "Monel" metal, by adding reduced nickel or copper powder, bronze powder, cobalt black, vanadium, &c., to the aluminium boat, by mixing potassium with the sodium to be peroxidized, or by mixing the catalysts with sodium peroxide powder before agglomerating.
