Title: Improvements relating to pasteurising apparatus for liquids
IPC: A23L3/16
Filed: 1935-11-15
Abstract: 466,107. Fluid - actuated valves. CREAMERY PACKAGE MANUFACTURING CO., Ltd., YATES, H., and PAGE, A. E. Nov. 15, 1935, No. 31644. [Class 135] [Also in Group VI] In pasteurizing-apparatus of the kind set forth in Specification 466,105, [Group VI], the operation of the filling and discharging means for the pasteurizing vessels is governed by a member driven by a constant speed motor, this driven member being associated with an indicator and with a starting means which are inter-related so that the starting means cannot be actuated unless the indicator is in the initial position. As shown, the motor 32, Fig. 2, drives through reduction gear at a speed of one revolution per minute a worm-wheel 49, Fig. 6, which has a projecting pin 49a co-operating with a lever 52, Fig. 3, pivoted at one end to the casing 51 of the device. The other end of lever 52 carries a driving pawl 53 which co-operates with the teeth of a ratchet wheel 54 fixed on a shaft 55 rotatably carried in the housing 51. A second pawl 56 also co-operates with wheel 54 to ensure rotation in one direction only, the pawls 53, 56 being connected by a spring 57 which keeps them in engagement with wheel 54 which has sixty teeth so that it makes one revolution per hour. The shaft 55 carries a cam disc 25 which operates the compressed air distributing valves B for the pneumatic actuating devices for the filling and discharging valves and for lifting the latch governing the pneumatically operated piston which controls the switch for the hot milk pump, all as set forth in Specification 466,106. The shaft 55 carries also a disc 46 having a slot 46a therein which is arranged to register with a projection 18d on an arm 18c of a shaft 18 which can be rotated by a knob 11 when the device is in the initial position to open the master valve of the compressed air supply and thereby start the cold milk pump and also the constant speed motor 32 by means of the ball switch, all as set forth in Specification 466,105, [Group VI]. The shaft 55 further carries a pointer 58 which registers with a chart 59 graduated to show the conditions in the several pasteurizing vessels, and the adjacent end 55a of the shaft is adapted to receive a key whereby the mechanism can be set by hand by forward adjustment only to a setting intermediate between the initial and final positions.

Abstract: Compounds of the formula <FORM:0832289/IV (b)/1> and acid addition salts thereof, wherein Y1 and/or Y2 represent hydrogen atoms or hydroxyl or etherified or esterified hydroxyl groups, R1 is an alkylene or hydroxyalkylene groups of 2-6 carbon atoms and R2 is an alkylene group of 2-6 carbon atoms are made by reacting a compound of the formula <FORM:0832289/IV (b)/2> wherein R11 is an alkylene, hydroxyalkylene or keto-alkylene group of 2-6 carbon atoms, with a compound of the formula <FORM:0832289/IV (b)/3> wherein R11 is an alkylene group of 1-5 carbon atoms and X is a halogen atom or a radical <FORM:0832289/IV (b)/4> and reducing the resulting amide of the formula <FORM:0832289/IV (b)/5> by known methods for reducing the group -NH.CO- into -NH.CH2-, reducing any keto-oxygen atom present in R1 into a hydroxyl group and converting any etherified or esterified groups Y1 and/or Y2 into free hydroxyl by hydrogenation or hydrolysis, if desired.  Suitably Y1 is a hydroxyl group, Y2 is hydrogen and the amide-forming reaction is carried out in a hydroxylic solvent such as an alcohol or Y1 and/or Y2 are hydrogen atoms or esterified or etherified hydroxyl groups and the reaction takes place in a solvent containing no free hydroxyl groups such as a hydrocarbon or an ether.  The reduction step is suitably effected with a complex metal hydride, e.g. lithium-aluminium hydride or sodium-boron hydride in the presence of an ether or by reduction with an alkali metal and an aliphatic mono- or dihydric alcohol, e.g. ethanol, propanol or glycol.  The quantity of reducing agent may be such that any keto group contained in R11 is reduced to a hydroxyl group and any esterified hydroxyl groups Y1 and/or Y2 are converted to free hydroxyl groups. If Y1 and/or Y2 are benzyl groups they may be subsequently converted to free hydroxyl groups by catalytic hydrogenation.  In examples (1) 1-p-hydroxyphenyl-2-amino-propanol-(1) is treated with phenoxyacetic anhydride and the resulting 1-p-hydroxyphenyl - 2 - a  - phenoxyacetamido - propanol-(1) is reduced with lithium aluminium hydride to 1 - p - hydroxyphenyl - 2 - b  - phenoxyethyl - amino - propanol - (1); (2) p - hydroxy - a  - amino-propiophenone is treated with phenoxyacetyl chloride and the resulting p-hydroxy-a -phenoxyacetamido-propiophenone is treated with lithium aluminium hydride to give the product of (1); (3) phenoxyacetic anhydride is used in place of phenoxyacetyl chloride in the process of (2) and (4) p-hydroxy-a -amino-propiophenone is treated with g -phenoxybutyryl chloride to give p-hydroxy-a -(g -phenoxybutyrylamido)-propiophenone which is reduced with lithium aluminium hydride to 1-(p-hydroxyphenyl)-2-(41 - phenoxybutylamino) - propanol - (1).

Title: Processes for the preparation of aromatic vegetable extracts
Inventor: GIRARDET ANDRE
IPC: A23F5/48
Filed: 1947-12-08
Abstract: An aromatic vegetable extract of, e.g. coffee, tea, mint, vervain and thyme, is prepared by an aqueous extraction and a concentration of the aqueous extract so formed practically to dryness, a water soluble physiologically inoffensive and moisture-retaining product being added either to the aqueous extract or to the water employed for effecting said extraction, characterized in that the concentraion of the aqueous extract is stopped as soon as the concentrate obtained is pulverulent and still contains from 5 to 10 per cent moisture.  The moisture-retaining product may be polyhydric alcohols such as pentaerythritol, sorbitol and mannitol; water-soluble cellulose derivatives such as methyl cellulose; water-soluble cellulose or starch degradation products; carbohydrates such as sugar; gelatin and polyvinyl alcohols of low viscosity.  The examples relate to the extraction of coffee in which sorbitol is added to (a) an aqueous extract prepared at 120 DEG C.; (b) the water used in the preparation of the extract; and (c) an aqueous extract obtained after first distilling off the coffee volatiles in vacuo at 130 to 150 DEG C. The aromatic volatiles are added to the extract-sorbitol mixture before or after spray pulverization.  The Specification as open to inspection under Sect. 91 comprises, as moisture-retaining products, inorganic salts.  This subject-matter does not appear in the Specification as accepted.

Abstract: 903,485. Slub catchers for yarn winding. ABBOTT MACHINE CO. Inc. Sept. 22, 1960, No. 32593/60. Class 120 (2). A slub catcher of the type in which the presence of a slub causes the yarn to be deflected laterally from a normal path Y, Fig. 3, to a path S where the yarn is caught, comprises two inclined blocks 10 and 11 between which the yarn passes, the blocks 10 and 11 being so formed in the region of the path Y that they have non- opposed yarn engaging surfaces 11a, 40a, Fig. 9, and a lateral spacing S between these surfaces that is less than the normal diameter of the yarn to be passed therebetween. The block 10 has a lower snagging blade 41 which, in conjunction with the block 11, forms a tapered snagging slit that traps the yarn as it is deflected towards the path S. The block 11, Fig. 1, is mounted on a pivoted shaft 18 such that it can be rocked away from the block 10 for cleaning purposes, and a spring 21 acts on the shaft 18 to bias the rear end of the block 11 against the block 10.
