Title: Container with lift tab cover release
Inventor: FOSTER JOHN ARTHUR
IPC: B65D43/02
Filed: 1968-03-06
Abstract: 1,147,130. Container closures. J. L. CLARK MFG. CO. 6 March, 1968, No. 10936/68. Heading B8T. A closed container comprises a cup-like body 10, e.g. of aluminium or plastics, having an external bead 14 and a sheet metal cover 12 with a skirt 13 engaged by means of an inward rib 27 beneath a downwardly facing shoulder 19 of the bead 14, a tab 16 forming an integral extension of the skirt. The tab 16, which is pulled outwards and upwards to tear the skirt along parallel scored or otherwise weakened lines 23 formed on its inner surface, is of curved cross-section to form a rigid cantilever, so that when it is pulled, it pivots about an axis 31. The cantilever effect ensures that the tab has greater resistance to bending below the axis 31 than the resistance of the cover to tearing along the weakened lines 23. A gasket 15 of compressible material ensures a tight seal. As the tab 16 is swung to the upright position, the gasket seal is broken between the tear lines 23, and on further pulling the inclined shoulder 19 cams the broken skirt ends outwardly, releasing the skirt progressively in both directions around the bead 14. The cover 12 may be replaced to reseal the container.

Title: Improvements in and relating to the production of aromatic carboxylic acids
IPC: C07C51/255
Filed: 1948-04-21
Abstract: A process for the production of p-toluic acid or a mixture of p-toluic acid and terephthalic acid comprises heating p-tolualdehyde or mixtures thereof with p-toluic acid, in a saturated liquid aliphatic acid diluent, in the presence of oxygen or a gas containing free oxygen.  The preferred temperature range is approximately from 10 DEG  to 150 DEG  C.  As oxidation catalysts may be employed organic and inorganic salts of copper, cobalt, nickel, silver, lead manganese, vanadium, calcium and tin.  Organic compounds tending to form peroxides under the reaction conditions and acting as oxidation initiators include aliphatic per acids, aldehydes, ketones and ethers, cycloaliphatic ketones, aromatic per acids, arolyl peroxides, olefines and cycloolefines representative of which are per acetic acid, acetaldehyde, propionaldehyde, isobutyraldehyde, acetone, methyl ethyl ketone, diethyl ketone, diisopropyl, diethyl and diamyl ethers, cyclohexanone, perbenzoic acid, benzoyl peroxide, octylene and cyclohexene.  The oxidation may be conducted at any pressure and in continuous operation the liquid components of the reaction mixture may be passed through a reactor concurrently with or countercurrently to the free oxygen-containing gas.  In examples: p-tolualdehyde is oxidized in the presence of acetic acid, propionaldehyde and manganous, copper and cobalt acetates (2), cobalt acetate (4), lead acetate and calcium carbonate (5), silver acetate (6), nickel carbonate and cobalt acetate (7), SnO2 and cobalt acetate 98), and copper and cobalt acetates (11). p-Tolualdehyde and p-toluic acid mixtures are heated in the presence of glacial acetic acid and propionaldehyde with, in examples (1) air, (3) benzoyl peroxide and oxygen, (10) copper and cobalt acetates and air.  Example (9) is similar to example (10), acetic acid being replaced by isobutyric acid.  The terephthalic acid formed may be filtered off and p-toluic acid obtained by evaporation of the aliphatic acid diluent.

[Also in Group XXXV] In a pump, which may be used for delivering milk under pressure to cream separators by means of a disc 50 inclined to the axis of the rotor 62, the disc is driven by magnetic means and the fluidpumping chamber is separated from the driving elements by a thin wall allowing the passage of magnetic flux. The pump casing 10 is of magnetic material, e.g. iron and is secured by a bracket 13 of non-magnetic metal to an electric motor 14, the pump and motor being mounted on a base 15. A cap 16, removable for cleaning purposes and closing the pumping chamber, is held in place by a bar 33 hooked over a projection on the casing 10 and having projections bearing against the cap when a wing-nut is tightened to press a sealing gasket 32 surrounding a hub 30 of the cap against a cylindrical member 27, which defines the pump cavity. A partition 21, dividing the pumping chamber from the driving elements, has an aperture which receives a flange on the member 27 and a thin diaphragm 43 of magnetic metal closes the aperture and is secured to an annular seating 44 of the member 27, e.g. by welding or brazing. The diaphragm 43 and the hub 30 are frustoconical and form bearing-surfaces for the disc 50, which disc has a rib 57 defining a guide surface which in conjunction with the edge 60 on tne diaphragm centres the disc when in motion. The rotor 62 is of magnetic material having an integral cranked projection 64 balanced by a projection 69 of non-magnetic material (brass), the outer ends of the projections 64, 69 being shaped to conform with the diaphragm and separated therefrom by a small air-gap. A sleeve 67 of magnetic material surrounds the rotor and is spaced from the rotor by an air-gap. Between the sleeve and the casing is an annular coil 66, whereby, when the rotor 62 is driven, a magnetic flux is produced and drives the disc 50 to convey fluid entering through an inlet 55 in the cap 16 to a passage 42 extending radially outwards from the member 27 through an openended slot in the casing. The reduced neck of the inlet may be threaded for attachment of a conduit from a gravity feed source and the outer end of the passage 42 is threaded for connection to a conduit. U.S.A.

Title: Apparatus for the transmission of force particularly applicable to the braking of motor road vehicles
IPC: B60T11/08
Filed: 1928-04-16
Abstract: 292,548. Soc. Anon. des Automobiles Unic. June 22, 1927, [Convention date]. Force - transmitting mechanism.-A force - transmitting mechanism particularly applicable for applying the brakes of motor vehicles, comprises two levers connected by a spring so that as long as the effort transmitted does not exceed the tension of the spring, the two levers move together, but when this effort is exceeded a locking device for one lever becomes operative and the velocity ratio is thereby reduced. The mechanism shown comprises a lever a pivoted at b carrying on a pivot g a second lever h to which are connected, in the case of brake mechanism, the rods l, n connected respectively to the hand lever and to the brakes. A spring k connected to the cranked arm i of the lever h and to the lever a normally holds the lever h against a stop j on the lever a and holds a detent d carried by the lever a out of engagement with a fixed rack p against the action of a spring e. Thus when a pull is applied to the rod l the levers a, h move together about the pivot b until the. brakes having been brought into engagement, the spring k yields permitting the detent d to engage the rack p. The lever a is thus held and the lever h turns about the pivot g, the effective pressure being thus applied to the brakes with an increased leverage.
