Title: Improvements in or relating to oligodynamically acting germicidal products
IPC: A61L2/238
Filed: 1935-06-04
Abstract: Germicidal products in the form of emulsions, salves, pastes, plasters, ovules, or plugs, having oils, fats, or salves as their basis, are prepared by distributing a compound comprising silver oxide and manganese oxides in chemical combination of a salt-like character, preferably silver manganite, in water-permeated oils, fats, salve bases, or mixtures thereof.  The silver oxide-manganese oxide compounds may be prepared by reacting silver nitrate solution with alkali permanganate and reducing the silver permanganate formed with dextrose or aldehyde.  They may be worked while still moist into oils or fats such as wool fat, further water being added if necessary, or into emulsions of oils or fats with water or aqueous solutions.  Other ingredients may then be added.  Alternatively, silica gel of high water content, e.g. 80-90 per cent, may be ground with the moist silver oxide-manganese oxide compound or an aqueous suspension thereof, preferably with addition of protective colloids such as sugar or gum arabic, and the product incorporated with oils or fats.  In a modification, the silica gel, before or after impregnating with the silver-manganese compound, is treated with alcohol to displace the water forming an alcogel.  Hydrocarbon gels, e.g. benzogel, can also be formed.  These products are then mixed with salve bases, or with aqueous liquids and then with fats or fatty esters and the like.  Specification 457,783 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 457,783, and the impregnation of suture threads with the silver oxide-manganese oxide compounds. Thus, sterilized gut is treated with a solution of silver nitrate and potassium permanganate and then washed, twisted, and dried.  It refers also to products containing, in addition to silver manganite, free silver and manganese oxide made, for example, by reacting a silver and a manganous salt in alkaline solution.  This subject-matter does not appear in the Specification as accepted.

Abstract: 743,275. Planing-machine details. KLOPP, F. June 16,1953 [Nov. 19, 1952], No. 16603/53. Class 83 (3). A fluid-pressure control arrangement for the pivoted tool-holder of a planing or shaping machine comprises a control-piston engaging the tool-holder for automatically lifting it during the return stroke, the working pressure for the control-piston being generated by an auxiliary piston, the stroke movements of which are positively controlled in relation to the motion of the ram head, and the pressure impulse from which directly produces the working pressure for the control-piston. The tool-holder 3 is pivoted at 4, upward movement being limited by an adjustable stop 34. A fluid-pressure piston 5 presses against the back of the tool-holder to give relief on the rearward movement of the hydraulically-operated ram 1. Pressure for operating the piston is obtained through a line 9 from an auxiliary piston and cylinder 7, 8, the piston being connected for movement with a main controlvalve 28. Pressure-fluid passes through an adjustable throttle-valve 10 and a ball-valve 12 allows the tool-holder to fall by gravity when the piston 7 moves downwards. A valvechest 17 above the cylinder 8 carries a reliefvalve 14 leading through a pipe 15 to a reservoir 25, and a non-return valve 18 which allows "make-up " fluid from a return part of the main circuit to enter the tool-lifting circuit when the piston 7 is on its downward stroke. A vulcanized-fibre plate 35 is held by a spring 36 against the rear top edge of the tool-holder to reduce shock when the latter is swung against its stop. The ram operation comprises a slide-valve 28 and two further slide-valves 31, 32, the former being a starting control and the latter a preliminary control valve. Automatic feed is effected by a ratchet 37 through rack-and-pinion gearing connected to the valve 28. A shaft 38 is unidirectionally rotated in steps and the motion transferred to a screwed feed-spindle 40 through a reversing gear. An auxiliary high-speed feed drive is provided by a motor 42. The pump 23 for supplying fluidpressure has a control 23a for varying the output and is driven by an electric motor 24.

IPC: A23C15/02
Filed: 1947-06-24
Abstract: A dairy product having a high milk fat content in the continuous phase is obtained from milk cream, or similar material containing milk fat in the dispersed phase by agitating the material by mechanical means at atmospheric or higher pressure to secure the uniting or coalescing of a substantial portion of the milk fat content, attempering said material to a temperature suitable for the separation hereinafter referred to either before, concurrently with or after such agitation, and subjecting the agitated and attempered material at said separation temperature to centrifugal separation to produce a separation product having a high milk fat content while the percentage of milk fat in other separated fractions of the material is substantially reduced.  The process may be carried out in the apparatus claimed in Specification 676,095.  The agitation step is preferably affected at a temperature of 30 DEG -90 DEG F. using a sour cream with a milk fat content between 20 and 40 per cent and an acidity of 0.2 to 1.5 per cent, which may be neutralized to less than 0.3 per cent by the addition of sodium or potassium hydroxide solutions or lime water.  The agitating step may be carried out in the presence of a gas such as air, nitrogen or carbon dioxide.  The separated product may be pasteurized and then reseparated to give a product having a milk fat content in excess of 95 per cent.  The composition and standardizing of the final milk fat or butter may be controlled by the methods claimed in Specification 666,631.
