Title: A closure for an aerosol or like pressurized container
IPC: B65D83/14
Filed: 1968-04-29
Abstract: 1,219,935. Dispersing liquids by gaseous pressure. SAMUEL TAYLOR PTY. Ltd. April 29, 1968 [May 2, 1967], No.20111/68. Heading F1R. A closure for an aerosol or like pressurized container having a neck and mouth comprises a cap placed on the mouth and over the neck, a substantially cylindrical element connected with the cap and extending into the neck with clearance from the interior wall of the neck, and a ring of elastically deformable material elastically and displaceably fitted over the circumference of the substantially cylindrical element, the ring being an interference fit within the neck and having a part of its surface exposed to the pressure prevailing within the container to assist the sealing effect. The cap 5 may be retained on the neck 10 of the container by friction or by a clip or, as shown, by crimping the free edge 28 over the end portion of the neck. The valve chamber 14 of the aerosol container is held by an annular flange 26 depending from the cap 5, a gasket 18 being interposed between the valve chamber and the cap. A sealing ring 21<SP>111</SP> of rubber or the like is forced by the pressure within the container into sealing engagement with an annular shoulder 27 and the inner wall of the neck 10. Instead of being slipped over the tapered outer surface of the annular flange as shown, the sealing ring may be slipped over the valve chamber 14 below the annular flange. In this case the interior pressure forces the sealing ring into sealing engagement with the free end of the annular flange, and the sealing ring may be of elliptical, rectangular or tear-drop cross-section. In the latter case, the tapering part of the cross-section extends into a tapering space between the valve chamber and the free end of the annular flange.

IPC: F16H63/30
Filed: 1928-07-11
Abstract: 298,186. Maybach-Motorenbau Ges. Oct. 5, 1927, [Convention date]. Variable-speed gearing comprises a two-speed gear with a pair of claw clutches the end faces of the teeth being bevelled to produce a catchup or speed equalizing effect before positive engagement. Thus in Fig. 3, the teeth of elements 3, 6 are pressed together by a spring such as 9, Fig. 1, and as long as 6 moves faster than 3, there is resistance to the relative. motion. Whenever 3 moves the faster in the direction of the arrows, Fig. 2, the teeth snap into engagement. The double clutch 3, Fig. 1, is splined on driving-shaft 1 and a one-to-one drive is effected when the elements 3, 6 engage. An overdrive is effected through the gear train when elements 2, 3 engage. Both clutches are modified according to the invention, and lever 7 is biassed by a spring toggle to have no neutral position. This two-speed gear may be used as auxiliary to another change-speed gear of the same or of a different type. The taper end faces on one clutch member may be replaced by rollers.
Patent GB-441334-A (GB)
Title: A process for the conversion of unsaturated alcohols and/or ethers into saturated aldehydes and/or ketones
IPC: C07C45/51
Filed: 1934-07-09
Abstract: Unsaturated alcohols or ethers are converted into saturated aldehydes or ketones by contact with solid catalysts having extended surfaces, steam being added if ethers are employed.  The reaction may be effected in the vapour phase or, with pressure, in the liquid phase. The alcohols may contain aryl, aralkyl or heterocyclic groups. Suitable catalysts are active alumina, active silica, diatomaceous earth, fuller's earth, silica gel, burnt clay, porous porcelain, pumice, brick screenings, and metals having highly developed surfaces such as reduced or colloidal copper.  When the catalyst has dehydrogenating effect, the reactions may be effected under pressure. In examples, isobutenol vapour is treated with active copper, active silica, active charcoal, porous porcelain, and pumice respectively, and isobutenol in the liquid phase is treated with reduced copper, porous porcelain, and active charcoal respectively; wet diisobutenol ether vapour is passed over porous porcelain; and wet isobutenol vapour is passed over brick screenings.  In each of these cases the product is isobutyraldehyde.  In other examples, 2-methylbutene-1-ol-3 is passed over silica gel, yielding methyl isopropyl ketone; and phenyl isopropenyl carbinol is passed over active alumina, yielding phenyl isopropyl ketone.  The Specification as open to inspection under Sect. 91 includes the use of catalysts which have "active surfaces" due to their chemical nature or degree of subdivision and mentions catalysts of an essentially basic character, metal oxides such as alumina, zinc oxide and thorium oxide and neutral substances such as silicates, including thorium silicate. An example is included of the use of zinc oxide for the treatment of 2-ethyl-propene-1-ol-3 which yields a mixture of a -ethyl propionaldehyde, a -ethyl acrolein and an unsaturated aldehyde containing 10 carbon atoms.  This example is said to be typical of the result of an incomplete rearrangement, a complex mixture of isomeric dehydrogenated and higher compounds such as saturated and unsaturated aldehydes and ketones being obtained.  The reaction can be controlled to yield various kinds of mixtures in which one component predominates. This subject-matter does not appear in the Specification as accepted.

INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) July 18, 1932, No. 20337. Convention date, July 16, 1931. [Class 38 (iii).] The motors M1-M3 of a multi-motor printing press drive are synchronised by being connected in parallel on their primary and secondary sides, and are started by rotating slowly a leading drive M1, the final parallel connections on the secondary sides of the motors being made only when the sections of the working-machine are displaced by less than a pole-pitch of their motors in relation to the leading drive. The various working sections drive brushes c of contact devices K1, K2, K3, over conducting segments a, b, corresponding segments b of the several drives being interconnected so that a current flows to close contactors S2, S3, which connect the secondaries in parallel, only when the working- sections are in correct relative positions. The leading drive M1 is driven at slow speed by a motor H through gearing Z and an overhauling coupling U. The Specification shows that with 4 pole machines driving their working sections through reduction gearing of 3-1, the segments b should number 36 for each section in order that the motor shafts shall be removed 30‹ from a proper synchronous position when their rotors are interconnected. The leading drive may be a separate motor not coupled to the working machine. During the positioning the auxiliary motor may have a large slip resistance, or slow speed may be obtained by alternately closing and opening its main circuit.

Title: A new or improved machine for making pats or rolls of butter
IPC: B65B3/32
Filed: 1926-08-23
Abstract: 257,289. Bruzzi, U. Aug. 21, 1925, [Convention date]. Stream-cutting machines; extrusion machines; rotary-table machines; feeding. - A machine for making pats and rolls of butter comprises a container 1, Fig. 1, an interchangeable turntable 14 carrying moulds for forming the pats, a delivery opening 29 from which the butter is extruded from the container by means of a piston and toothed change speed gear for regulating the speed of the turntable in relation to the size of pats to be produced and to the number of moulds carried on the turntable. The moulds comprise cavities in each of which a spring-controlled piston 19, Fig. 5 is depressed to eject the moulded pats of butter. Each mould is provided with an adjustable screw 27 to limit the stroke of the corresponding piston and thus vary the capacity of the mould. In the illustrated form the springs act indirectly on the piston rods through pivoted levers 22 which revolve with the turntable. The delivery passage 29 is arranged to connect with the succeeding mould before the filled mould is moved away by the rotation of the turntable. When forming rolls, the extruded rope is supported on two semi-cylindrical supports 31 turning about a common axis 33 and acting in conjunction with a cone to cut off the length desired. The rope-extruding opening is closed by a plug when forming pats, and the mould-carrying turntable is put out of action when forming rolls. An overflow aperture is provided in the container to prevent excessive pressure therein during the extrusion process. A throw-off device 4 operated by a disc 6 actuated from the piston prevents the latter from advancing beyond a predetermined point in the container.
