Title: Improvements in apparatus for the garaging or storage of vehicles or goods
Inventor: O'SULLIVAN EUGENE
IPC: E04H6/24
Filed: 1957-06-26
Abstract: 905,901. Mechanical garages and other storage systems. NEW ERA MULTI-PARK HOLDINGS Ltd. Sept. 25, 1958 [June 26, 1957], No. 20198/57. Class 78 (4). Containers 1 for vehicles or goods are moved vertically in two adjacent columns within a framework by hydraulic rams 2, 3, each container resting on the container below it, and trolleys 4, 5 are provided to transfer containers from one column to the other. In one embodiment, Fig. 2, on reaching the top of the column, bars 8 on the container 1 pass between hooks 9 secured on pivotal axes 10 on the trolley 5 and on moving the trolley to the right, a roller mounted on an arm on the axis 10, Fig. 3 (not shown), engages a cam rail 13 causing the hooks 9 to pivot and engage beneath the bars 8 to support the container and to transfer it to the column on the right where the rail 13 is shaped to allow the hooks 9 to release the container. In a second embodiment, Fig. 4, claw arms 9 are freely mounted on shafts 16 above the shafts 10 which are provided with quadrants 17 adapted to engage the inner sides of the claw arms 9 to maintain the arms in an open position as shown in broken lines. As a container 1 rises to the top of a column, it engages a telescopic member 20, mounted on the trolley 5, which actuates a ratchet mechanism 23 through links 21, 22 to rotate the shafts 10 through 45 degrees by chains 25, 18, allowing the hooks 9 to engage the bars 8 on the container. On transferring the container to the other column, the column is raised and lowered to operate the ratchet mechanism again to rotate the shafts 10 through a further 45 degrees, thereby opening the claws 9 to release the container. In a modification, Fig. 6, an electric motor 26 is used to rotate the shafts 10, a sector switch on one shaft 10 and switches 27, 27<SP>1</SP> mounted on cranks 28, 281 pivoted on the trolley being connected to the motor so that operation of switches 27, 27<SP>1</SP> by movement of a container relative to the trolley or at the limits of travel of the trolley causes the shafts 10 to rotate through 45 degrees to open or close the claw arms 9. During transfer of a container from the bottom of the descending column to the bottom of the ascending column, the columns are supported by ratchet mechanisms, as described in Specification 888,693. Specification 693,170 also is referred to.

Title: Improvements in a system of lubrication for internal combustion engines
IPC: F01M3/04
Filed: 1923-08-10
Abstract: 224,301. Dehn, F. B., (Ironsides Co.). Aug. 10, 1923. Lubricant conveyed by fluid. - Lubricant is drawn from a container 1, Fig. 1, through a pipe 2 into the intake manifold 4 of an internal - combustion engine by the suction existing in the manifold, a valve being interposed between the container and the pipe to regulate the supply automatically in accordance with the speed of the engine. In the form shown in Fig. 2, a tapered valve 9 is secured to a diaphragm 6 mounted on an annular flange 7 in a valve casing 3 and held in place by a screwed plug 8. The valve 9 co-operates with a seat formed in a screwed stem 10 held in adjusted position by a spring 12. Oil is drawn by the suction in the manifold from the container 1 through an inlet 13, past the valve 9, through an orifice 14 in the stem 10 and through an exit 15 into the pipe 2. The valve is normally open, but as the suction increases, due to slowing of the engine, the diaphragm 6 and valve 9 are pulled toward the valve seat, thus reducing the supply of oil. In the form shown in Fig. 3, a tapered valve 17 is normally held against a seat 18 by an adjustable spring 16. The suction draws the valve away from its seat, and increasing suction causes the opposite face of the valve to approach a seat 21, thus diminishing the supply of oil. Specification 15597/12 is referred to.

Title: Improvements in or relating to the curing or smoking of animal or vegetable materials
IPC: A23B4/048
Filed: 1930-07-10
Abstract: Caoutchouc is preserved and cured by treatment with a liquid condensation product obtained by dry distillation of wood at about 400 DEG  C., the product being freed, before use, from tar oils by fractional condensation, from methyl alcohol by fractionally distilling, and from acids by neutralization.  The liquid has the smell, taste and curing properties of wood smoke.  The treatment may be effected by dipping the substance into the liquid product which may be concentrated or diluted.  The liquid product may be obtained by distilling the wood in a retort having three or four receivers connected in series and cooled separately.  The liquid distillate, to which may be added a small amount of the insoluble bodies from the first two receivers which are separated mechanically from the distillate, is next gently boiled for at least 45-50 minutes, after addition of sodium carbonate or bicarbonate.  The methyl alcohol is thus boiled off, the aromatic substances present being retained, and the acetic acid and pyromucic acid are neutralized and eliminated. Finally further sodium bicarbonate may be added to the boiling liquid which is then held under pressure for several minutes, after which the liquid is filtered free from phenols and is ready for use.ALSO:Meat, fish, poultry, sausages, caviare, caoutchouc, or other animal or vegetable substances are preserved and cured by treatment with a liquid condensation product obtained by dry distillation of wood at about 400 DEG  C., the product being freed, before use, from tar oils by fractional condensation, from methyl alcohol by fractionally distilling, and from acids by neutralization.  The liquid has the smell, taste, and curing properties of wood smoke. The treatment may be effected by dipping the substance into the liquid product which may be diluted with brine or water.  Meat &c. is pickled by first immersing for a few days in a mixture of the liquid product and brine, the red colour appearing in meat after 2-3 days, and in bacon after 5-8 days, and then dipping into the concentrated or diluted liquid product and subjecting to the action of warm or hot air in an oven.  Sausages may be preserved by adding the product to the sausage meat.  The liquid product may be obtained by distilling the wood in a retort having three or four receivers connected in series and cooled separately.  The liquid distillate, to which may be added a small amount of the insoluble bodies from the first two receivers which are separated mechanically from the distillate, is next gently boiled for at least 45-50 minutes, after addition of sodium carbonate or bicarbonate.

Title: New heterocyclic compounds
Inventor: HOGGARTH ERIC
IPC: G03C1/34
Filed: 1951-09-05
Abstract: The invention comprises pyrazolo-pyrimidines (tetra-aza-indenes) of the formula <FORM:0716327/IV (b)/1> where R1 is hydrogen or amino, R2 is alkyl and R3 is amino, alkylamino, dialkylamino or hydroxy.  These are made by the action of hydrazine on 4-alkylthio-6-alkyl-5-formyl- or 5-cyano-pyrimidines; when R3 is hydroxy it can also be produced by hydrolysis of an amino group.  Examples show the production of the 6-amino-4-methyl and 3 : 6-diamino-4-methyl compounds, the latter being hydrolysed to the 3-amino-4-methyl-6-hydroxy compound.  The pyrimidines used as starting materials are prepared as follows: 2-amino-4-methylthio-5-nitro-6-methylpyrimidine is made from the 4-chloro compound and methanethiol and the nitro group then reduced. The resulting 2 : 5-diamino-4-methylthio-6-methylpyrimidine is diazotized and treated with (1) formaldehyde, sodium acetate and copper sulphate to give 2 - amino - 5 - formyl - 4 - methylthio - 6 - methylpyrimidine, and (2) sodium cyanide and nickel sulphate, yielding 2-amino-5-cyano-4-methylthio-6-methylpyrimidine.

Abstract: A modified polyester resin composition is prepared by mixing 100 parts of a polyester having an acid value of 10 to 100 with a copolymerizable ethylenically unsaturated monomer in such an amount that the final modified polyester resin composition contains 5 to 80% of the monomer, and with 0.1 to 3 parts of a magnesium aluminium or calcium oxide, hydroxide or alkoxide in which the alkyl group contains 1 to 6 carbon atoms, and with 1 to 15 parts of an aliphatic monocarboxylic acid having from 6 to 24 carbon atoms, and heating the resulting mixture in the presence of a polymerization inhibitor at a temperature of from 140 to 250 DEG F. for a period of 5 minutes to 40 hours, whereby the said monocarboxylic acid becomes linked to the polyester through a metal linkage to produce a plasticized resin composition of increased viscosity. A small amount of a dehydrating agent, e.g. calcium chloride, may be present during the heating.  The polyester to be modified is prepared by heating, usually from 280 to 480 DEG F. for 4 to 20 hours, a mixture of one or more glycols with one or more alpha-beta-ethylenically unsaturated polycarboxylic acids; a dicarboxylic acid or its anhydride normally being used. Glycols and polycarboxylic acids mentioned are ethylene; diethylene; triethylene; 1-3, propylene; 1-2, propylene; dipropylene (1, 3 or 1, 2); butylene or styrene glycols and maleic, fumaric, phthalic, aconitic, mesaconic, citraconic, ethylmaleic, pyrocinchoninic, and itaconic acids, with or without other acids.  Alternatively the polyester to be modified may be a solid Diels-Alder reaction product of rosin or abietic acid with a fumarate polyester of a glycol and fumaric acid, Copolymerizable ethylenically unsaturated monomers mentioned are styrene, vinyl toluene, vinyl acetate, diallyl phthalate and triallyl cyanurate. Aliphatic monocarboxylic acids mentioned are caproic, caprylic, capric, lauric, myristic, palmitic, stearic, arachidic, baheric, 9-dodecenoic, 9-tetradecenoic, 9-hexdecenoic, 9-octadecenoic, 9-eicosenoic, 13-docosenoic, linoleic, linoleric, oleic and mixtures of such acids e.g. tall oil acid. Magnesium, aluminium and calcium compounds mentioned are magnesium oxide, hydroxide and methoxide, calcium oxide and hydroxide and aluminium propoxide. Inhibitors mentioned are hydroquinone, quinone, tertiarybutyl catechol, parabenzoquinone and copper.  The modified polyester resin composition can be cured in the presence of fillers such as calcium carbonate, if desired, to a solid, infusible, insoluble, cross-linked state under the influence of a polymerization catalyst and/or "promoters" e.g. peroxidic materials such as benzoyl peroxide, tertiary butylhydroperoxide, methylethylketone peroxide, cobalt and manganese catalysts, as well as such promoters as N-methylaniline and diethylaniline. The cured product can be used to make coated and shaped articles and laminates. Specification 941,067 is referred to.
