Title: Improvements relating to tables and shelves
IPC: A47B31/00
Filed: 1945-10-09
Abstract: 594,004. Stands. CARWARDINE, G. Oct. 9, 1945, No. 26349. [Class 52(iii)] Movably mounted shelves or trays which may be associated with a table, service waggon, or other article of furniture are arranged to swing about a vertical axis and also to have a translatory movement towards and away from said axis and the movements may be dependent or independent one upon the other. As shown a service waggon has two movable shelves which, in the in-position, register with fixed trays or tables a, d, e, a central pillar c being provided. The movable shelves f abut one another about a sleeve h rotatable around the pillar c and are slidable outwardly upon arms g carried by the sleeve h. To pins l on the underside of the shelves f are pivoted links k the other ends of which are pivoted to a rod j passing through a slot in the pillar c and also serving to support the sleeve h and therefore the shelves f. Rotation of the shelves f in the direction m causes the shelves to recede from one another and from the pillar c until they are as far apart as possible when rotated to a position at right angles to that shown in Fig. 3. The shelves f may be adjusted in height by arranging the rod j in a slot in the pillar c and mounting it in a stirrup carried by a screwed rod mounted within the pillar c. The shelves may be drawers which by the rotation of a chest cause the drawers to move in and out.

Title: Aqueous polyepoxide compositions for treating textiles
IPC: D06M15/55
Filed: 1960-07-29
Abstract: Methallyl ethers of glycols or polyalkylene glycols are peroxidized with peracetic acid, or another peroxidizing agent.  In examples A, polyethylene glycol was reacted with methallyl chloride in presence of caustic potash and the diethyl ether of diethylene glycol. B. To a fraction of the product corresponding roughly with the dimethallyl ether, peracetic acid in ethyl acetate was then added to yield polyethylene glycol bis (2, 3-epoxy-2-methyl propyl) ether.  C. Ethylene glycol bis (2, 3-epoxy-2-methyl propyl) ether was prepared by peroxidation of ethylene glycol dimethallyl ether.  D. Di-ethylene glycol-bis (2, 3-epoxy-2-methyl-propyl) ether was similarly prepared.ALSO:Aqueous liquid mixtures comprise a polyepoxide, an epoxy curing agent and a buffering agent present in sufficient amount to maintain a pH between 5.5 and 7.5, to stabilize the mixture against hydrolysis. Suitable polyepoxides are listed. Preferred ones contain more than one methylglycidyl ether group.  The curing agents are acids, acid salts or Lewis acids.  Suitable buffering agents are ammonium hydroxide, and the oxides, hydroxides or salts of magnesium, calcium, strontium, barium, zinc or cadmium.  The mixtures are useful for treating textiles, the resin being cured within the textile by heating e.g. at 120 DEG -200 DEG C. following a drying step at lower temperature.  Other textile finishes, e.g. aminoplasts such as dimethylol ethylene urea 1,3, dimethylol -5- ethyl hexahydro -S- triazinone, urea- or melamine-aldehyde condensates may be added to the liquid mixtures as well as conventional additives.  In typical examples aqueous mixtures of 4-vinyl cyclohexene dioxide and zinc fluoborate were stabilized with ammonium hydroxide, zinc oxide, zinc acetate or zinc carbonate.  In other examples the polyepoxide was (IX) 1,2-bis (2,3-epoxy-2 methyl propoxy) ethane. (XVI), (XVIII), (XIX), (XX), ethylene glycol bis(2,3-epoxy -2- methylpropyl) ether.ALSO:Textiles especially cellulosic or cellulose-containing materials are treated with stabilized aqueous mixtures containing epoxy resins and epoxy resin curing agents, (see Division C3) dried and heated to cure the resin.  The compositions may also contain other known textile finishes, especially nitrogenous ones e.g. urea- or melamine-aldehyde condensates or derivatives thereof.  Fabrics may be rendered crease resistant without diliterious effect on their wash and wear properties.  In a typical example, cotton fabric was immersed in an aqueous mixture containing 4-vinyl-cyclohexene dioxide, zinc fluoborate, and zinc oxide to bring the pH to 5.5-7.5, dried at 77 DEG C. and cured at 140 DEG C.  Other examples use other poly-epoxy compounds, curing and buffering agents and in some cases include other textile finishes, e.g. dimethylol ethylene urea; 1, 3-dimethylol-5-ethylhexahydro-5-triazin-2-one; or melamine- or urea-aldehyde resins, in the compositions.

Title: Improvements in or relating to the production of modified oils, such as linseed oil
IPC: C09F7/00
Filed: 1952-10-21
Abstract: Linseed oil and oils having similar properties are modified to produce quick-drying oils, or oils more suitable in the production of alkyd resins, by treating the oil with finely divided metallic zinc at a temperature not exceeding 200 DEG F. over a relatively long time.  The zinc may be granulated or powdered zinc, preferably blown zinc dust.  Zinc dust made by volatizing zinc and cooling the vapour in an inert gas is suitable.  The zinc is mixed with the oil and maintained in suspension with occasional and gentle stirring preferably at room temperature for 4 to 6 days: less desirably, the mixture may be heated to 180 DEG -200 DEG F. for 18 to 30 hours, e.g. to 200 DEG F. for 24 hours.  The zinc dust is then allowed to settle and the oil is decanted off.  The decanted oil may then be filtered or centrifuged.

Patent GB-268369-A (GB)
Abstract: 268,369. National Cash, Register Co., (Assignees of Arnold, C. H.). March 26, 1926, [Convention date]. Clutches, claw for use with the operating-gear of cash registers &c. A pair of pawls are controlled for engagement with a driving ratchet wheel by means of a relatively shiftable cam plate. To the worm-wheel 82 driven by the motor is pinned a ratchet wheel 84 adapted to be engaged by a pair of pawls 85 carried by a disc 86 rigid with the pinion 87 in train with the main shaft of the machine. The pawls are controlled by a cam plate 90 rotatably supported by a plate 95 carried around by the worm-wheel and ratchet-wheel but forced to the right (Fig. 3). to engage frictionally the pawl-carrying disc 86, by the action of springs 97 surrounding pins 96 secured to the plate 95. When the machine is released for operation the lever 54 is rocked c'ear of the switch-operating parts to close circuit for the motor, and the forked end of the lever also frees the extension 92 of the cam-plate 90 to allow this, under its frictional drive, to turn counterclockwise (Fig. 4), to force the pawls into driving engagement. At the end of the cycle the descent of the forked end of the lever in addition to breaking the circuit obstructs the extension 92 and the resulting relative displacement of the plate 90 removes the pawls from engagement.
Patent GB-729645-A (GB)
Title: Improvements in or relating to can openers
IPC: B67B7/46
Filed: 1951-11-16
Abstract: 729,645. Can-openers. FARANDATOS, D. Nov. 16, 1951 [Nov. 21, 1950], No. 26847/51. Class 66. A can-opener is provided with a readily removable cutter blade and built-in electromagnetic means for magnetizing the blade. The opener comprises a base portion 12 for attachment to a table top 10, or the like, and having bosses 15, 16 which constitute bearings for vertically movable standards 17 supporting a head portion containing the cutter blade 66, solenoid 87, means for rotating the cam 8, and associated gear within a cover 40. When not in use the head portion rests on the base portion and is locked there by a spring-pressed bolt 98 on the head engaging with a latch 29 in the base. At the same time a vertically slidable member 100 on the head enters an opening 101 in the base 12 and passes behind latch 29 to prevent it being disengaged from bolt 98. To use the opener the switch 83 must be closed to energize the solenoid 87 which by its pole-pieces 91 and 93, attracts a plate armature 36 so that lifting the head tends to operate bell-crank 32<SP>1</SP> to disengage latch 29 from bolt 98 against the action of spring 31. But this is prevented by the member 100 behind latch 29 ; so the finger grip 67 must be pulled back to turn levers 104, 1.03 about pivot 57 and thereby lift member 100. The finger grip 67 also serves to retain the blade 66 in position in its guide 70 by means of the bolt 63 and the release operation therefore reminds the operator to lift out blade 66 (by means of its handle 68) and clean it. The head may then be raised by means of handle 49 to enable a can 8 to be positioned on the base where its rests on flanged wheel 24 and radial rollers 22. The handle 49 is pivotally connected to shaft 46 and in lifting the head of the opener the handle is automatically raised from the position in Fig. 2 to that shown in Fig. 1, and cam surface 51 depresses a sleeve 52 against spring 56 and liy means of the arm 54 turns a casting 60 about pivot 57. The casting 60 carries the blade 66 in its guide 70 so this latter action moves the point of the blade 66 away -from a traction wheel 47, mounted on the end of shaft 46, and allows the rim of the can to enter therebetween. A sharp blow on the head causes the bla,de to pierce the can top and the handle is brought to the horizontal position (Fig. 2) and turned to perform the cutting operation. The spring 56 maintains firm pressure on the can rim between the blade 66 and traction wheel 47. Besides magnetizing the blade to attract small particles of metal, the solenoid 87, by means of its poles 91 and 93, serves to hold the top of a can after it has been severed. Copper bands 92 and 94 are placed around parts of the two poles respectively, making them into shaded poles. The solenoid and wiring is encased in waterproof plastic so that the head portion of the opener may be spray-washed.

Abstract: 1,014,220. Centrifugal separators. STARCOSA G.m.b.H. June 30, 1964 [July 25, 1963], No. 27002/64. Heading B2P. A screw centrifuge for separating solids with different grain sizes from a liquid suspension comprises a solid-walled drum I within which screw conveyers 10, 21 rotate respectively at a relatively high and a relatively low differential speed with respect to the drum 1, the conveyer 10 discharging the total solids and the conveyer 21 transporting mainly the solids with fine grain sizes towards the conveyer 10. The drum 1, driven by a V-belt pulley 3 drives the screw conveyers 10 and 21 through epicyclic gears 5 and 29 respectively. The suspension is fed via an inlet 33, annulus 34, apertures 35 and conical inlet cup 36 to the interior of the drum of conveyer 10 and passes from there through apertures 37 into the deposition chamber between the conveyer drum and the drum 1. In this chamber, the coarse-grain-solids are separated, the fine-grain-solids and the liquid passing into the chamber between the drum of conveyer 21 and the drum 1. In the latter chamber, the finegrain-solids are separated and transported by the conveyer screw towards the conveyer 10 to be discharged with the coarse-grain-solids through apertures 23 and a pipe 25. The clarified liquid flows out over a weir 26 and through a discharge pipe 27. In a modification, the screw conveyer 21 is mounted on a hollow shaft extending into the drum of the screw conveyer 10 and through which the suspension is fed. The hollow shaft is driven from the drum 1 by a belt and pulley arrangement or by toothed wheels. In a further modification, the feed apertures 37 are provided in the wall of the drum of conveyer 21 close to the partition between the conveyer drums.

[Class 38 (v).] A pneumatically operated switch comprises a spring controlled piston 3 having an extension 3<a> on which are mounted adjustable nuts 12, 121 which engage rollers 11 on a stirrup 6 pivoted at 5 and connected by a tension spring 10 to the free end of a stirrup 7 also pivoted at 5. A pin 17 on the stirrup 7 engages the forked end of a lever 18 pivoted at 19 carrying contacts 24 co-operating with fixed contacts 25. On an increase in pressure, the piston 3 rises and lifts the stirrup 6 until the spring 10 passes across the axis 5 causing the stirrup 7 to snap rapidly upwards lifting the lever 18 to break the circuit. By this disposition of levers the contact pressure is increased.

An electric ignition device for explosive detonators Mz comprises a main capacitor C1 charged positively through a rectifier Gl1 below the breakdown voltage of a spark gap Sp1 and an ignition capacitor C3 fed through a resistor R3 from an auxiliary capacitor C2 charged negatively through another rectifier Gl2. The capacitor C1 is charged to a peak voltage of 1100 volts and when the ignition capacitor C3 reaches a value of 300 volts spark gap Sp1 breaks down which causes a spark gap Sp2 having a breakdown value of 600 volts to pass the capacitor C1 charge to the detonators. The resistor R3 and capacitor C2 are sized so that the capacitor C1 reaches its maximum voltage before the capacitor C3 reaches 300 volts. The circuit may be supplied from the mains or from a spring-driven A.C. generator G. R1 and R2 are discharge resistors and R4 substantially prevents C1 discharging into C3. Short-circuiting switches (not shown) may also be provided to discharge the capacitors.
