Abstract: 353,744. Hexagonal paper bags. CONTINENTAL PAPER & BAG CORPORATION, 220, East 42nd Street, New York, U.S.A.-(Assignees of Falk, T. S.; 160, Sterling Place, Brooklyn, New. York, U.S.A.) Sept. 2, 1930, No. 26152. Convention date, Sept. 18, 1929. [Class 94 (ii).] An hexagonal bag is formed from a paper tube 1 having longitudinal creases which divide it into six panels 3 .. 8, the front and rear panels, 3, 6 being unfolded and the side panels 4, 5, 6, 8 being folded at 9 . . 12 to form gussets.' The depth of the gussets is substantially a quarter of the width of a panel, so that half the width of a side panel is exposed, and the tube folds flat to a width of two panels. Slits 3 of the depth of a quarter of a panel are made in the folds 9 . . 12 prior'to the tube end being :opened out to form triangular bottom flaps 14. After applying,paste within the ,areas a, a, b, b, one side flap is folded inwards about the line 18 midway between the centre line 17 and one corner of the triangular flap 14 and the second side flap is similarly folded upon the first flap. When the bag is opened out, the line 17 defines the base of the sides and determines the length of the diagonal of the completed hexagonal base, the gussets providing small triangular folds 22 in the bottom before forming part of the sides.

Abstract: 383,688. Fuel and air regulators for steam boilers. DOBLE, A., 190, Sea Cliff Avenue, San Francisco, U.S.A. Sept. 21, 1931, No. 26366. [Class 51 (i).] The movements of a part of a boiler tube 6 due to expansion and contraction are transmitted to fuel control devices by an element secured to the tube and made of a metal having the same coefficient of expansion as that of the tube. The tubular element 32 is welded to the boiler tube and may be enclosed by a loop in the tube. A quartz rod 36 in the element engages a rocker arm 37 which, upon expansion of the boiler tube, first engages with the lever of the feed valve 9 to allow water to enter the boiler.

Title: Process for the preparation of ethylene diamine
IPC: C07C/
Filed: 1960-07-29
Abstract: Ethylene diamine is prepared from hydrogen cyanide, aqueous formaldehyde, ammonia and hydrogen by feeding into the reaction zone one or more streams of the above containing a molar excess of ammonia relative to the hydrogen cyanide or formaldehyde whichever is present in the lesser amount, and heating the mixture at between 90 to 130 DEG C. at 3,000 p.s.i.g., at least, in the presence of a hydrogenation catalyst. The streams are free of hydroxyacetonitrile or aminoacetonitrile and the catalyst may be an activated metal catalyst e.g. nickel or cobalt which may include a promotor, for example a metal of Group IB, IIB, VIB, VIIB, or VIIIB of the Periodic Table.  The process may be continuous and either or both the excess ammonia and hydrogen streams may be recycled.

[Also in Division H1] A process for the electrolytic development of an exposed photo-conductive insulating layer of CdS or ZnO in an insulating binder having coated thereon a layer of an hydrophilic polymer e.g. gelatine, polyvinyl alcohol or carboxymethyl cellulose is characterized in that the hydrophilic polymer layer or the aqueous electrolyte contains an addition polymerizable ethylenic monomer which is soluble in water or a polar solvent containing water. Specified ethylenic monomers are acrylonitrile, acrylamide, acrolein, acrylic acid, polyethylene glycol di-methacrylate and glycerol di-acrylate. The electrolyte or the hydrophilic polymer layer may contain water-insoluble inorganic salts e. g. sodium chloride; a thermal addition polymerization Inhibitor e. g. hydroquinone; a catalyst capable of giving a free radical by oxidation or reduction e. g. an iron or cerium salt; a compound capable of giving a formazan dye on reduction e. g. triphenyl tetrazolium chloride or a pigment e. g. carbon black. The photo-conductive layer may be coated on a conductive aluminium layer, glass coated with tin oxide; paper containing carbon black or metal filaments or paper adhered to aluminium foil and may comprise as binder epoxy esters of aliphatic acids, vinyl chloride - vinyl acetate copolymers, styrene-butadiene copolymer and polyvinyl chloride and contain pigments e.g. colloidal silica, clay and Ti O 2  and dye sensitizers. The hydrophilic polymer layer may be applied before or after exposure and exposure may take place simultaneously with development. The electrolyte may be present in an electrolytic bath or absorbed on a sponge, brush or porous paper and development may be carried out using a sponge in the form of a roller. The image may be rendered visible by washing out unexposed areas or selectively dyeing the exposed or non-exposed areas. A dye relief image may be transferred on to a gelatine coated glass plate.

Title: Improvements in or relating to variable capacity rotary hydraulic pumps and motors
Inventor: JOHNSON EDWARD HARRY

Filed: 1950-11-06
Abstract: 696,649.. Rotary engines or pumps. KEELAVITE CO., Ltd. Nov. 1, 1951 [Nov. 6, 1950], No. 27078/50. Class 110(ii) An engine (or pump) of the rotary-abutment type, such as described in Specification 551,991, in which the capacity of the working-chamber is varied by an axial movement of an end-wall C', is provided with automatic valve apparatus which controls the flow of fluid through passages 5<SP>3</SP> 5<SP>4</SP>, leading to the working chamber B and recesses F <SP>2</SP> respectively. Outflow of fluid from B and F<SP>2</SP> occurs when the pressures therein exceeds the inlet pressure to the engine, and inflow fluid when the pressures therein are less than the fluid pressure at the exhaust port. Either port L or M may be the inlet, the valve apparatus automatically allowing for the reversing of the pressures and reversal of the rotor shaft H carrying vanes H<SP>4</SP>. The recesses F<SP>2</SP>, and opposite flats F<SP>7</SP>, of the abutment, are connected by passages F<SP>4</SP>, F<SP>5</SP> respectively. The motor, preferably, is contained within a casing A which is filled with fluid under a pressure intermediate the pressures in the ports L, M. Gears F<SP>3</SP>, H<SP>3</SP> couple the two shafts F, H together. A link N is used to move the shaft H, and its rotor H<SP>1</SP>, axially. In Fig. 2, a valve R will close a passage R<SP>1</SP> or R<SP>2</SP> depending upon which port M or L is at high pressure. This pressure, through a pipe Q, acts on the end P<SP>1</SP> of a differential piston P. While the pipe Q is always at high pressure, a pipe P<SP>7</SP> is always subjected to the lower pressure. The larger end P<SP>2</SP>, of the valve P, is subjected to the pressure of fluid in the casing A, and a port P<SP>4</SP> is. also open to A. When the pressure in the casing A drops below the mean of the pressures in P<SP>3</SP> and P<SP>5</SP>, the valve P will be moved to the right so as to open the port P<SP>4</SP> and admit additional working, fluid from the end P<SP>3</SP> to the casing. When the wall C<SP>1</SP> is moved to the left to decrease the capacity of the motor, fluid will be able to escape from the chamber B when it is shut off between the two vanes H<SP>4</SP>, Fig. 2, by way of the passage 5<SP>3</SP> and a valve 5. If the wall C<SP>1</SP> moves to the right, to increase the capacity of the motor, fluid can be drawn into the port 5<SP>3</SP> from the pipe P<SP>7</SP> through a valve 5<SP>1</SP>. In an alternative arrangement, Fig. 7 (not shown) the valves 5, 5<SP>1</SP> are duplicated for the passage 5<SP>4</SP>. The Provisional Specification also refers to Specifications 524,503 and 551,482.

The hold door of an aircraft which in its lower portion is of circular cross-section, has substantially the same shape as that part of the fuselage on which it is mounted, and opens and closes by lateral movement externally of the fuselage along a circular path adjacent the fuselage wall, and the door comprises a retractable panel movable to reveal a recess in the door enabling the door to accommodate an obstacle on the fuselage. In Fig. 1, the fuselage is of double bubble section, and has two doors 6, which on opening move over the outside of the fuselage wall. Where a wing 4 is in the way of complete opening of each door, a part 7 of the door is movable relatively to the remainder to form a cut-out which fits over the wing. Fig. 17 shows one door closed, and the other open, the door part 7 having a roller 38 in a cam track 43 on door 6, so that when door 6 is moved in the direction of arrow f, by chain-and-sprocket mechanism (not shown), it moves radially outwardly enough to overlap part 7 which is stationary. Thereafter, the two door parts move together up the fuselage wall. The doors are guided by rollers moving along rails fixed to the front and rear edges of the door opening.
