Title: An improved coin operated lock
IPC: G07F17/14
Filed: 1932-03-01
Abstract: 394,437. Coin-freed door locks. GELDART, E. F., 2, Nicholas Road, Heavitree, Exeter. March 1, 1932, No. 6117. [Class 27.] Fastenings for doors; coin action, mechanicalconnection.-A door is held closed in its frame by a spring latch H attached to the frame engaging a lock attached to the door, an inserted coin with the intermediary of a single sliding piece D being used to push back the latch when a handle is turned or slidden. This door-operating handle may pass through a square socket G to move the slide D through a coin and another slide C by a lever F and pin L. A spring S1 returns the handle on release to its original position and the coin drops into a till in the lock casing. An exit handle engages the slide D by a pin K and lever E to press back the latch H to open the door from the inside. This handle is returned to its original position on release by a spring S2. Indicators.-"Vacant " and " Engaged " signs may be duplicated on the front and back of the lock connected by a rod O to a plunger P which is operable inside the door. This plunger is held by a spring S3 in a position showing " Vacant," but is depressed by hand to show " Engaged," a button T pressed out by a light spring holding the plunger P depressed by a lever R pivoted at U. Coin-slit closing devices.-A lever W, Fig. 3, is pushed across the coin slot by cam action when the indicator is moved to " Engaged," and a second lever is also always across the coin slot except when the door is shut or very nearly so, by a lever 7, Fig. 1, on a projection on the jamb of the door. Removal of the till of the lock uncovers a pin or screw removal of which enables front of the lock including the front of the straight short coin slot to be removed to permit removal of the lock mechanism.

Title: Improvements in or relating to amino acid products and method of producing same
IPC: A23J3/32
Filed: 1947-03-05
Abstract: Proteins are hydrolysed to amino acid products suitable for parenteral administration by mixing an aqueous mineral acid of a normality of 0.75-1.5 with 6-8 per cent of its weight of protein for each unit of normality of said acid, heating until 60-65 per cent of the total nitrogen has been converted to a -amino nitrogen, neutralizing, and separating the amino acid and any other hydrolysis products from insoluble inorganic salts.

Title: Improvements in or relating to methods of purifying crude phthalic anhydride
IPC: C07C51/573
Filed: 1949-03-10
Abstract: Phthalic anhydride is obtained from crude phthalic anhydride by heating a mixture of the crude anhydride and at least 0.0035 mol. per mol. of phthalic anhydride in the crude anhydride of an inorganic acid oxidizing agent or sulphur trioxide or hydrogen peroxide at a temperature above 270 DEG  C., adding thereto at least 0.001 mol. of an alkali metal nitrate per mol. of phthalic anhydride in the crude material, heating the resulting mixture at a temperature above 270 DEG  C. and for a period of time sufficient to permit separation of phthalic anhydride from the impurities therein by distillation, and then separating phthalic anhydride from the mixture in purified form. The crude phthalic anhydride may be obtained from the vapour phase catalytic oxidation of naphthalene.  The crude anhydride can be given one or more distillations prior to the above process.  The amount of oxidizing agent employed may be substantially equivalent to that required to oxidize the reducing impurities in the crude material, e.g. from 0.0035 to 0.04 mol. per mol. of phthalic anhydride in the crude material.  The inorganic acid oxidizing agent may be nitric or sulphuric acid.  The heating with the oxidizing agent and the crude phthalic anhydride may be carried out at a p  temperature above 270 DEG  C., but not substantially in excess of the boiling-point of phthalic anhydride at atmospheric pressure and without substantial loss of phthalic anhydride vapours, and may be continued for a period of time sufficient to substantially complete the reaction between the oxidizing agent and the reducing impurities in the crude anhydride, e.g. for a period of from 1 to 3 hours.  The amount of alkali metal nitrate employed may be from 0.0015 to 0.01 mol. of alkali metal nitrate per mol. of phthalic anhydride in the crude.  The alkali metal nitrate may be lithium, sodium, potassium or caesium nitrate and may contain water of crystallization.  The heating with the alkali metal nitrate may be conducted at a temperature above 270 DEG C. but not substantially in excess of the boiling-point of phthalic anhydride at atmospheric pressure and without substantial loss of phthalic anhydride vapour, e.g. for a period of 1 to 3 hours.  The phthalic anhydride may be separated from the mixture by distillation at sub-atmospheric pressure, e.g. at an absolute pressure below 400 mm. of mercury.  A number of detailed examples are given.

Abstract: 220,015. Soderlund, O., Boberg, T., Testrup, N., and Techno-Chemical Laboratories, Ltd. March 7, 1923. Fats and fatty oils, extracting by pressure.- In expressing liquid from moist material by pressure between rolling surfaces, the contents of the entry cavity between a pair of rolls is divided to form a plurality of films by a series of travelling partitions moved through the bite of the rolls together with and by the co-operation of the material. Fig. 4 shows diagrammatically an arrangement of rolls 1, 2, with six intermediate endless bands, to the spaces between which the material under treatment is delivered. Flexible endless bands e - - e<3>, Fig. 5, surround vertical rolls b, b<1>, the material being delivered by a hopper g<1> with feed-screw or worm and a feed-box g. The pressure spaces have upper and lower cover plates g<3>, g<4>, Fig. 8, and are limited on the approach side by vertical positioning bars g<5>, Figs. 7 and 8, which also support. scrapers h to remove dried matter adhering to the bands and rolls. The material may pass into the bite as a layer extending the full width of the pressure surfaces, or pillars with control slots i<1> may localize the feed to restricted strips occupying the central portions of the pressure surfaces. Alternatively the material may be delivered to each division of the bite by a separate tube with a right-angled spout, directed towards the bite. Wipers or Mowing or suction devices may be provided for removing the extruded liquid from the edges of the bands and rollers. The interior of the rolls may be heated by hot gases, live steam, or recompressed vapour generated from previously treated matter. The apparatus may be enclosed in a casing in which a heated atmosphere is maintained. The endless bands mav be of different materials and may be of steel or rubber, and of reticulate or perforated material.
