Title: Improvements in or relating to means for collating typewriting work sheets
IPC: B41L1/22
Filed: 1922-07-06
Abstract: 201,731. Wherry, J. A. July 6, 1922. Sheet-feeding arrangements.-Main and supplementary sheets or forms intended to receive duplicate typed entries are temporarily secured together in the required relative position by means of a notch in the top or bottom edge of the main sheet and a fold in the supplementary sheet; the sheets may be provided with scales, and the main sheet may have a slot for securing a carbon sheet. A ledger sheet 1 is formed in the top edge with a notch 4, and a bill 7 has an extension which is folded to engage the notch. The ledger sheet is provided with a scale 2 representing line-spaces, and the extension of the bill is provided with lines 8 arranged at line-space intervals and numbered in reverse order to the scale 2. When a fresh bill is applied to the ledger sheet, the fold in the bill is made on the line 8 that is numbered one in excess of the number of lines already typed or written on the bill, the bill being thereby brought into such position that the first entry-line thereon is imposed on the first vacant line on the ledger sheet. In a modification, the notch is made in the bottom edge of the ledger sheet, and the bill is provided at the bottom with an extension having the numbered lines 8. The ledger sheet may have a slot 3 for securing a carbon sheet 5, the top edge being passed forward through the slot and doubled over the notch 4, and the body of the carbon sheet being then folded over the front of the ledger sheet.

A blade being projected by finger pressure slides up a curved surface 9 on the bar, as the latter is depressed by the finger, and is located in its outward passage by a projection 11 passing through its slot. In other embodiments (not shown) the bar may have an upward projection for locating an issuing blade or a projection may be provided on the magazine top in front of the blade stack, an issuing blade sliding down the projection until the latter enters its slot. The curve 9 may be shaped to provide varying resistance to the forward movement of blades at different levels or this may be achieved by having a different friction coefficient at different portions of the curve. The invention may be applied to magazines having feed slides. Specification 647,820 is referred to.

Title: Selective fluorination and extraction of beryllium-containing ores
IPC: C22B35/00
Filed: 1961-05-29
Abstract: The beryllium content of ores, e.g. 1/2 -14%, is selectively extracted by intimately mixing beryllium-containing ore of 100 mesh (Tyler standard) or finer, with a predetermined amount of an inorganic ammonium fluoride salt which is just sufficient to react with the metal content of the ore to give NH4BeF3, or sufficient to react with all the metal content of the ore, and reacting the mixture at a pressure of at least 200 p.s.i., e.g. up to 700 p.s.i., and at a temperature of at least 200 DEG  C., e.g. up to 700 DEG  C. for a time to react completely the fluoride.  The ammonium fluoride salt may be a silico-, ferric-, or bi-fluoride, a fluoborate, or a hexafluophosphate, and the ore/salt ratio for the silicofluoride may be 1.0 : 0.5-1.2.  In an example, beryl (100 mesh or finer) is mixed with ammonium silicofluoride and placed in a mild steel tube with welded end caps which is placed in a furnace at 450 DEG  C. for 6 hours.  The product is then removed, crushed, and leached with water to give NH4BeF3 while leaving SiO2 and NH4AlF4.  NH4F is also produced and reacts with beryl to give BeF2, AlF3, SiO2 and NH3, which may react with any SiF4 produced to give 2NH3.SiF4.  The NH4BeF3 may be reacte with NH4F to give (NH4)2BeF4, which may be reduced to Be.

Title: Manufacture of organic peroxides
Inventor: QUIN DENIS CHESELDEN
IPC: C07C409/16
Filed: 1955-07-05
Abstract: Peroxides of the formula <FORM:0792558/IV (b)/1> where Ar is an aryl radical, R1, R2, R3 and R5 are aliphatic groups, and R5 is an aliphatic or an aryl radical, are made by reacting a hydroperoxide of the formula <FORM:0792558/IV (b)/2> with a carbinol of the formula <FORM:0792558/IV (b)/3> in a molar proportion of hydroperoxide to carbinol of from 1:0.8 to 1:1.6 and at a temperature below 60 DEG  C. in solution in an aliphatic carboxylic acid which is a solvent for both reaction components and for water and in the presence of perchloric acid or sulphuric acid as catalyst, and rendering the catalyst in the reaction mixture ineffective before recovering the peroxide. Aliphatic carboxylic acid solvents mentioned are formic, acetic, propionic and butyric acids.  The reaction may be effected between room temperature and 35 DEG  C. with a hydroperoxide-carbonol mixture in a solution of up to 50 per cent by weight and free from water. The starting materials may be mixtures of pure hydroperoxides and carbinols, or crude hydroperoxides from the oxidation of aromatic hydrocarbons with molecular oxygen followed by removal of unreacted hydrocarbon, or crude carbinols from the chemical reduction or hydrogenation of hydroperoxides.  In a preferred embodiment, a hydroperoxide-containing reaction mixture prepared by oxidation is divided into two parts, one part being reduced to the carbinol and returned to the mixture.  Alternatively, the hydroperoxide-containing mixture may be hydrogenated until half is converted to the carbinol. After the condensation reaction, the catalyst is rendered ineffective by adding basic alkali-metal or alkaline earth metal compounds or alkali-metal or alkaline earth metal salts of the aliphatic acid used as solvent, and the acid solvent is then distilled off and the residue added to water or dilute aqueous alkali to separate solid peroxide.  The acid solvent may be re-used after distillation. Alternatively, the condensation reaction mixture may be added directly to water.  The crude product is pressed out to remove oil and recrystallized. The oil contains unreacted carbinol and may be recycled after optional distillation.  In examples: (1) phenyl dimethyl carbinol, obtained by reducing cumene hydroperoxide with aqueous sodium sulphite, is reacted with cumene hydroperoxide in acetic acid and in the presence of perchloric acid to give dicumyl peroxide; (2) dicumyl peroxide is similarly obtained from a starting mixture made by oxidizing cumene with molecular oxygen at elevated temperature, removing cumene, dividing into 2 parts, hydrogenating one part in the presence of palladium on activated alumina and re-combining it with the other part; (3) sulphuric acid is used instead of perchloric acid.

An electrical winding 13 surrounds the tube within ferromagnetic cap 14 which with washers 15, 16, 17 forms a magnetic circuit completed by a twopart ferromagnetic core 18, 19 and plunger core 32. Part 18 is fixed within the tube 1 and is threaded at 20 for nut 21 securing cap 14. Part 19 is axially displaceable within part 18 by threaded end 24 engaging in threaded bore 23 and rotatable by screwdriver slot 30; a lock nut 25 retaining it and a gasket ring 26 providing a seal. A non-magnetic stop 29 is screwed into threaded bore 27 for screwdriver adjustment lockable by nut 31 and sealed by gasket ring 36. The ferromagnetic plunger core 32 is longitudinally slotted at 33 to allow passage of fluid, and is screw-connected to spool 6 against biasing spring-34 and adjustable stop 35 setting the initial position of the spool. The airgap between core and plunger is set by adjusting non-magnetic stop 29, and the operative position of plunger 32 is set by adjusting part 19 of the stationary core. The effect of these adjustments on the characteristics of the device is illustrated graphically (Fig. 2, not shown).
