Title: Method of preservation of fruit and vegetables
IPC: A23B7/148
Filed: 1952-02-25
Abstract: Comestibles, especially fruit and vegetables, are stored and preserved in an air space in a container which is submerged in water so as to compress the air in the container and render the air humid. Fruit so stored at 5-15 DEG C in air of relative humidity 80-100 per cent and gauge pressure of 0.1-0.2 atmospheres will keep for some weeks.  The container may be ventilated by introduction of air under pressure through ducts leading into the air space.  Oxygen may be supplied to the container by electrolysis of water or by means of a substance which in the presence of water supplies oxygen and absorbs carbon dioxide.  The apparatus comprises a container which is closed at the top and open at the bottom and is adapted to be submerged in water so that air will be trapped and compressed in the upper parts of the container, and supports for the comestible disposed in the container above the level to which the water will rise when the container is submerged.  The apparatus may be submerged below the level of the sea or a lake, and, when so used, may be loaded for immersion and unloaded for raising.  Apparatus in which the container is provided with a charging opening and an airtight cover therefor may be installed on board ship or in a railway vehicle, the container being placed in a open tank which is filled with water after the container has been charged and the cover applied.

Title: Improvements in combination locks
IPC: E05B37/10
Filed: 1923-02-20
Abstract: 211,345. Cozens, G. H., and Secord, F. H. Feb. 20, 1923. Locks, permutation; padlocks. -In a permutation lock in which a concentric series of notched discs are operated by to and fro rotation of a handle, the handle carries a pointer moving over a graduated dial for sight setting, and a finger which passes noislessly through a spaced series of spring clutches for setting by feeling, and the handle operates a disc concentric with the permutation discs but having an eccentric hole the edge of which is always in contact with a pin on a spring-pressed bolt so that rotation of this disc operates the bolt. The circular casing 1 has non-rotatably mounted in it, a disc 12 with a slot 13 forming a guide for the bolt 34 and a concentric series of holes 14 into any one of which a pin 15 may be placed. A cylindrical guide 16 is screwed to the disc 12 by a flange 17 and contains the locking discs 27, each with a central hole 28 with a notch 30 and a pair of diametrically opposite pins 29 projecting above and below the disc. The discs are spaced apart by annular members 22. Surmounting the notched discs and concentric with them is a, disc 31 provided with an eccentric circular hole 32, a pin 38 carried by the bolt contacting with the edge of this hole. The handle 7 has a flange 8 with an annular recess 9 which fits rotatably on a flange 26 of the uppermost annular member 25. The bent-down part 5 of the cover-plate 2, secured by a flange 3 of the casing 1, prevents removal of the handle. A pointer 45 moves over a dial on the outside of the cover-plate 2 and the flange 8 carries a rigid finger 10 which, on rotation of the handle, passes inaudibly through a regularly spaced series of spring clutches 18 formed from extensions on the member 16, so that the lock can be operated by " feel." Fig. 1 shows the invention applied to a. padlock, a lug 37 on the bolt 34 engaging a notch in the leg 42 of a shackle sliding through holes 43 in the casing. To unlock, the handle 7 is rotated in a certain direction until all the discs 27 move as one, and until the single pin 29 on the underface of the lowermost disc contacts with the fixed pin 15 on the disc 12, preventing further rotation. This is the " zero " position and rotation of the handle in the opposite direction for a given amount sets the lower disc and to and fro rotations set the remainder so that all the notches 30 are aligned for entry of the pin 38. The last rotation of the handle by pins 11 on it engaging pins 33 on the disc 31, throws the eccentric hole 32 over to the left, the pin 38 following under the action of the bolt spring (not shown), the pin 38 entering the notches 30 and allowing the bolt to slide to disengage its lug 37 from the shackle, which can then be removed. The combination is changed by placing the pin 15 in any of the holes 14.

Title: Printing machine for punched paper
Inventor: LANEGAN FREDERICK EDWARD
IPC: B41F17/00
Filed: 1956-02-17
Abstract: 826,232. Printing-machines; feeding webs. OVERPRINT MACHINE CO. Ltd. May 16, 1957 [Feb. 17, 1956], No. 4965/56. Classes 100(1) and 100(2)  A rotary printing machine for printing punched paper strip 25 comprises a continuously rotated printing roller 6, a pressure-applying roller 8 cooperating with the printing roller to advance the strip 25 simultaneously, and print thereon, and an intermittently driven pin wheel 24 to draw the strip from the printing roller 6 and roller 8, which release the punched paper at least once in each revolution of the roller 6, the rotary movements of the wheel 24 and roller 6 being so timed that the former is at rest at the, commencement of each printing operation so that a loop 38 of strip is formed between the roller 6 and wheel 24 to maintain this portion of the strip in slack condition during printing. The printing roller 6 carries a pinion 13 having toothed portions 16, 17 and cut-away portions 14, 15. The pinion 13 meshes with a pinion 12 having cut-away portions 20, 21 and toothed portions 18, 19. The pinion 12 drives a sprocket wheel 11 which drives a chain 23 passing around a sprocket wheel 22 on a shaft 5 carrying two pin wheels 24 adjustable therealong. The printing roller 6 carries printing plates 7, 7<SP>1</SP> spaced apart around the periphery of the roller. In operation, the strip 25 is drawn from a pile 26 over a supporting plate 27 by the rollers 6 and 8, the drive to the pin wheels 24 being so timed that they are stationary during the commencement of the printing operation. The loop 38 is thereby formed in the portion of the strip between the rollers 6, 8 and pin wheels. This loop ensures that this portion of strip is maintained in slack condition during printing, thereby avoiding tearing of the strip. Soon after the commencement of printing the pin wheels 24 are driven and continue to be driven after the printing roller and pressure rollers cease to feed the strip by reason of the gap between printing plates. A guide plate 32, hinged on a rod 33, maintains the strip in engagement with the pin wheels while a vertical guide 34, adjustable along a slot 36, deflects the strip vertically downwards. Spring-urged ballpoint pens 42 are mounted for adjustment laterally of the strip in one or more slots, such that one or more lines of the required position are ruled on the passing strip. Ruling may be effected as a separate operation. In this case the roller 8 is lowered and the pin wheels 24 are continuously driven. If desired, the ballpoint pens may be replaced by pencils or rotatable wheels supplied with ink. If desired, the printing roller may carry a series of number-carrying drums actuated by a cam so as to print consecutive numbers on the strip. Instead of two printing plates, one or several plates may be carried by the roller 6.

Filed: 1973-02-01
Abstract: 1392592 Transistor circuits MOTOROLA Inc 1 Feb 1973 [30 May 1972] 5157/73 Heading H3T [Also in Division G3] A transistor circuit for producing from a reference current I an output current I + NIB comprises one or more transistors 36 in series with a further transistor 37, a transistor 39 coupling the collector and base of transistor 36 and transistor means 42 coupling the bases of transistors 36 and 37, the output-current being produced in a further transistor 22 having its base-emitter path in parallel with the baseemitter path of 37. As shown, the collector current of 37 is I + I B  and the emitter current therefore I + 2I B . The similar transistor 22 therefore has a collector current of I + I B  and the collector current of transistors 24 or 26, whichever is conducting, is I and therefore equal to the reference current. Transistor 42 may be replaced by a diode connected transistor (52, Fig. 3, not shown). A further -transistor (36<SP>1</SP>, Fig. 4, not shown) in series with 36 connected at its base to a further semi-conductor will cause the output current to be I + 2I B . The circuit may be used in a fuel injection system to linearly discharge two capicators alternately at the same rate. The elimination of the base current term in the output current increases the stability.

Title: Improvements in or relating to phenol-aldehyde resin adhesives
IPC: C09J161/06
Filed: 1950-03-02
Abstract: An aqueous thermosetting liquid phenolic adhesive having not over 40 per cent total solids content is made by dissolving in an aqueous thermosetting phenol-aldehyde resin syrup a lesser proportion, compared to the resin solids content. of an alkali-soluble proteinous adhesive base, the syrup having, when adjusted to 40 per cent resin solids, a boiling water bath gel time of less than 100 minutes, a pH between 9.5 and 12, and being free from aldehyde odour.  The resin syrup is preferably made from phenol, formalin and caustic soda, though meta-cresol may be substituted wholly or in part for the phenol.  Other reactants specified are mixed phenols containing not over 25 per cent by weight of alkyl phenols, other than meta-cresol, except 3 : 5-xylenol and resorcinol which, if present, should not exceed 10 per cent by weight of the phenols, acetaldehyde, furfural, and sodium carbonate, which may partly replace the caustic soda.  The syrup may be made from 1.1 to 3.5 mols. of aldehyde and from 0.3 to 1.2 mols. of caustic soda per mol. of phenol, provided that at least 1/7 mol. of caustic soda is used for each mol. of aldehyde.  Excess aldehyde is destroyed by reaction with the caustic soda.  Modifiers, which may be used in making the syrup, are caustic soda, caustic potash, calcium hydroxide, sodium silicate and pine oil.  Proteinous adhesive constituents specified are: soyabean flour, other oleoginous seed meal flours, soluble blood albumen, and solubilized keratin. Fillers specified are nutshell flour, china clay, bentonite, wood flour, bark flour and waste sulphite liquor solids.  The resin syrup may be spray-dried to form a powder which can be re-dissolved in water prior to making the adhesive, or the complete adhesive composition may be spray-dried and stored.  The syrup employed in the examples is made by refluxing phenol and formalin with an initial portion of caustic soda until a desired viscosity is attained, and subsequently adding increments of aqueous caustic soda with refluxing after each addition, until the desired degree of condensation has been attained.  Numerous examples are given.  The adhesives may be used for making fir-plywood, laminating paper and other sheet materials, and for binding comminuted materials to produce hot-pressed shaped articles.

Title: Process and apparatus for the purification of metals
Inventor: PAGONIS GEORGE ARISTOS
IPC: C22B9/04
Filed: 1961-02-14
Abstract: A crucible in a metal refining apparatus (see Division C7) includes a molybdenum sleeve lined with a refractory of the following composition:- .ThO2.75-95% .HfO2.6-10% .ZrO2.3- 7% .Y2O3.1- 3% A fused mixture of the refractory components is crushed and mixed with polyethylene glycol and stearic acid.  The mixture is then partially dried and rammed into a molybdenum sheath at 32,000 p.s.i.  The sheath and lining are heated to 800 DEG  F. under a vacuum of 10-2 mm. Hg.ALSO:<PICT:0956154/C3/1> Metal to be purified is melted under an inert atmosphere and then flushed with an inert gas passed upwards through the melt; the flow of flushing gas is then stopped, a supra-atmospheric inert gas pressure is applied above the molten metal and the melt allowed to remain quiescent to permit non-volatile impurities to settle out.  The purification may be a step in an alloy-forming process performed in the apparatus shown which consists of a charging section A and melting, purifying and alloying crucibles B, C, and D respectively.  The crucibles are interconnected by sampling and transfer valves E and are connected to inert gas and high vacuum lines.  In operation, the metal to be melted, e.g. Ti, is placed into the charging section and after surface degasification is moved by a hydraulic ram to a preheating chamber in the wall of the crucible B. Here it is preheated to 2000  DEG F. in an inert atmosphere and then pushed into the crucible B by the hydraulic ram. The Ti is heated to 3270  DEG F. and flushed with inert gas from a line 214.  The metal may be sampled by allowing it to fill a small recess in the valve E from which, after solidification, it is ejected for analysis. The remaining metal is transferred to the crucible C by establishing a pressure differential between the two vessels.  A slug of scavenging elements is preheated in a top section G and then dropped into the molten metal which is agitated by inert gas flushing.  Volatile impurities are condensed in a cooled part of G and heavier impurities are allowed to segregate. The purified metal is then transferred to crucible D, with sampling at E, and preheated alloying elements from a top section H are dropped into the metal melt which is stirred by inert gas flushing.  The melt is then heated to 3450  DEG F. and a small quantity of SO2 gas injected for grain refinement.  The alloy is finally vacuum-cast into a mould 136.
