Title: Improvements in or relating to the manufacture of hydrogen cyanide
IPC: C01C3/02
Filed: 1944-10-25
Abstract: Hydrocyanic acid is made by passing carbon monoxide and ammonia over a manganese dioxide catalyst at a temperature between 450 DEG C and 700 DEG C.  The manganese dioxide may be in powder form or deposited on a carrier but is preferably used in the form of a composition made by mixing the oxide with cement and water, in the ratio of 1 part of oxide to 1 to 6 parts cement.  After setting in thin slabs, the mixture may be aged for 3 to 6 months and then broken up for use. The reaction takes place in a tube containing the catalyst, heated to a temperature preferably between 550 DEG  and 600 DEG C.  Pressure may be used if desired, and other gases such as nitrogen or hydrogen may be admixed with the reacting gases.  The ratio of carbon monoxide to ammonia is preferably between 6 and 40 to 1 by volume, and the space velocity between 10 and 100 litres of ammonia per hour per litre of catalyst.  The gases leaving the reaction zone may be washed by an anhydrous weak acid, such as glacial acitic acid, and cooled to condense out aqueous hydrocyanic acid, which can be obtained in a pure state by fractional distillation.  The excess carbon monoxide may be recycled.  Examples are given showing the effect of varying the condition on the conversion.

Title: A composition and process for producing a synthetic resinous foam and the resulting foam
IPC: C08J9/10
Filed: 1952-08-22
Abstract: A cured resinous foam is produced by mixing a thermally decomposable blowing agent, a hardening agent containing an amino group and a thermally hardenable glycidyl ether of a polyhydric phenol having an epoxy equivalency between 1.0 and 2.0, and allowing or causing hardening to take place.  The blowing agent is preferably liquid or solid at 20 DEG C. and produces gas when heated at 50-200 DEG C.  The preferred proportion used is 0.5-5 per cent.  It should be uniformly distributed throughout the mixture.  Suitable agents are ammonium carbonate; ammonium sodium or potassium bicarbonate; diazoaminobenzene; diazoaminotoluene; 1, 3, bis(o-xenyl)triazene; 1, 3-bis(p-xenyl)-triazene; p, p1-oxy-bis-(benzenesulphonyl hydrazide); diazodiisobutyronitrile; dinitroso pentamethylene tetramine; diphenyl - 4, 41 - di(sulphonyl azide); cinnamoyl azide; furoyl azide.  The glycidyl ether is preferably prepared from epichlorhydrin and a polyhydric phenol.  Lists of suitable phenols are given.  Preferably the glycidyl ether has a viscosity of 50-300 centipoises at 100 DEG C.  The viscosity may be reduced by addition of a solvent, e.g. acetone, methyl ethyl ketone, isophorone, toluene, xylene, ethyl acetate, butyl acetate, chloroform or trichloropropane.  Suitable hardening agents for curing the foams are ethylene diamine, diethylene triamine, triethylene tetramine, diacetone diamine, hexamethylene diamine, diethylamine, dibutylamine, n-butylamine, and benzylmethylamine. Optional ingredients of the mixtures are surface-active agents, e.g. polyalkylene glycol ethers of sorbitan mono-esters of acids such as lauric, stearic or oleic; thermally hardenable glycidyl ethers of polyhydric alcohols (a list of suitable polyhydric alcohols is given in the Specification) and plasticizers, pigments, dyes, fillers and lubricants.  The heat of curing of the glycidyl ether may be sufficient to decompose the blowing agent and cause expansion during the setting reaction; the temperatures of the initial mixing being if desired slightly raised, or external heat may be supplied as well.  If too much heat is generated some of it may be used to drive off a volatile component of the mixture, e.g. water or one of the solvents previously mentioned.  The foams may be used for protective covers and radar equipment especially radomes for radar-carrying aircraft as space-filling material in laminated structures, or for thermal or accoustical insulation.  A number of examples are given of specific compositions and processes within the scope of the invention.  The glycidyl ethers employed were derived from epichlorhydrin and 2, 2-bis-(4-hydroxyphenyl propane).  In one case it was mixed with an ether derived from glycerol and epichlorhydrin.  In this case the density of the product was 104 lbs./cu. ft. but in general the derivatives fall between 4 and 20 lbs./cu. ft.

Filed: 1924-09-09
Abstract: 243,471. Marks, E. C. R., (Hart Manufacturing Co.). Sept. 9, 1924. Switches, quick-action; handles. - In order that switch handles made of porcelain or like material shall indicate accurately the " off," " on," and other positions of a switch, a projection 14 fixed to the switch spindle 12, instead of engaging the handle 15 directly fits closely in a notch in a plate 40 which has a lug 41 engaging a notch 43 in the handle. The lug 41 is some distance from the axis 12 so that the bad effect of the necessarily loose fit between the lug 41 and the porcelain handle is largely eliminated. The spindle 12 is screwed into a sleeve 23 which is inserted into a hole in the handle and held in place by a collar 25 which is slipped over the sleeve and itself held in place by a split ring 26, a spring 24 being interposed between the collar 25 and the end of the sleeve 23. On top of the collar 25 are placed the plate 40 and another plate 31 both plates being retained in place by the overturned ends 34 of the collar 25. The lug 14 may engage any one of three holes 30, 30<a>, 30<b> in the handle. Corresponding holes are provided in the plate 40 to allow the passage of the lug, but the plate 31 has only one such hole 32 and serves to cover up the holes 30<a>, 30<b> so that the handle will aways be set in the same position. Other plates to be used in place of the plate 31, are provided with the hole 32 in a position corresponding to the holes 30<a> or 30<b>. The invention is shown applied to a quick-action switch, rotation of the handle, and therefore of the spindle 12, serving to stress a spring 18 and eventually actuate a, contact-carrying member 17 loosely mounted on the spindle.

Title: Improvements in clockwork time fuzes for projectiles
IPC: F42C9/04
Filed: 1937-08-03
Abstract: 499,885. Projectile fuzes. WATKINS, A. H. (Industrial Commodities Development Corporation) Aug. 3, 1937, No. 21335. [Class 9 (i)] A clockwork fuze of the kind which is driven by the energy stored in a spring by inertia-operated means upon discharge of the projectile, is characterized in that the spring is compressed axially and, at the end of rotation of the timing member, imparts an axial displacement to the latter to effect ignition directly. In the construction shown in Fig. 1, -the inertia - member 12A which is prevented from rotating by keys 12B, sets back upon discharge of the projectile until projections 12C engage with recesses 16A at the end of a sleeve 16 projecting from the rotor 21 housing the clockwork mechanism, thereby compressing the helical driving spring 9 and preventing actuation of the clockwork. At the end of the acceleration period the spring 9 moves the member 12A forward until centrifugal segments 76 engage a shoulder 77 in the fuze cap 4. The compressive force of the spring 9, through the intermediary of a sleeve 13A provided with rollers 20 which engage in helical grooves 19 formed on the outside surface of the sleeve 16, rotates the clockwork housing 21, now freed from the restraint of the clutch 12C, 16A, until four rollers 44A, disposed unsymmetrically around the circumference of the housing become aligned with correspondingly disposed longitudinal slots 59A in the base of the fuze, whereupon the rotor 21 is driven rearwardly by the spring 9, and the firing pin 47 mounted in the base of the rotor is driven into the primer. When the fuze is at safe, a pin 62 is held in engagement with the casing of the rotor 21 by a set screw 40 ; the pin 62 is withdrawn from the rotor by centrifugal action during the flight of the projectile. The invention is shown applied to a combined time and percussion fuze in Fig. 5, in which construction the rotor spindle 16 is slidably keyed to the inertia member 12A, the driving spring 9 being mounted between the member 12A and the rotor 21. In the base portion 1 of the fuze is secured by screws 81 a sleeve 78 provided with three helical grooves 19A in which engage three rollers 20A on the rotor. When the fuze is set, the rollers 20A move along the grooves 19A, thereby compressing the spring 9. The inertia member 12A is provided with centrifugal segments 76 which, at the end of the acceleration period, engage against a shoulder 77 in the nose cap 7, and the spring 9 then drives the clockwork rotor 21 until the rollers 20A align with slots 59A in the sleeve 78, which allow axial movement of the rotor and firing pin 47 to effect ignition. The primer 64 is retained in position during the trajectory by spring-loaded centrifugal catches 67, but is driven against the firing pin 47 upon impact of the projectile with the target. According to a modification, the rollers 20A may be replaced by toothed pinions, the grooves 19A formed as helical racks.

Title: Improvements in and relating to seamless hollow articles used for packages and to their manufacture
IPC: B29C41/18
Filed: 1920-07-15
Abstract: 168,745. Faber, J. July 15, 1920. Capsizes. - Thin, seamless, transparent skins or hollow bodies capable of being crumpled and suitable for enclosing confectionery, chocolate, &c., are produced from solutions of skinforming cellulose derivatives, the skins being formed by evaporation under the vapour pressure of the solvent, air being excluded. A suitable solution, such as acetyl cellulose dissolved in acetone, or a benzol solution of a cellulose derivative, is poured into a hollow mould a which is covered by a similar mould b, the pair being then inverted. When a skin has formed on the walls of mould a the moulds are separated, mould a being hung up to dry in the air or in an atmosphere of indifferent-gases when the skin formed on the walls can be easily detached from the mould. Mould -b is meanwhile covered bv a second' mould a and the process repeated, mould b being dried this time. Several layers of the same or different materials may be superposed to form the hollow bodies. The process can be carried out on a large scale by fixing a number of moulds in a frame and manipulating them inside a closed vessel partly filled with the solution. The solution employed may be either concentrated or weak; the Specification states that to produce thin-walled articles from concentrated solutions the vapour pressure must be allowed to act for a longer time than is the case when the solutions are weak.
