Patent GB-876590-A (GB)
Title: Improvements in or relating to cement applying apparatus
IPC: A43D25/18
Filed: 1956-08-30
Abstract: <PICT:0876590/III/1> <PICT:0876590/III/2> In a cement-applying apparatus, the rate of feed of cement in rod form into the apparatus is regulated by the amount of cement in the apparatus immediately available for application to workpieces. The regulating device may take the form of a pressure-sensitive diaphragm or a vane operated by the build-up of adhesive in a part of the apparatus adjacent to the applying member.  In a machine for applying cement to the backs of books, Figs. 2 and 7, a rod of solid thermoplastic cement S is drawn into the machine by corrugated roller 20 and a similar co-operating roller, not shown. These rollers are driven by an electric motor through chain drives and a separable clutch 256, 257.  The rod of cement is fed along passage 94 into a melting and applying unit constitued by disc 56 rotating in a recess in a heated casing 48, a passageway 160 diminishing in size towards the part indicated 162 being formed between said disc and said <PICT:0876590/III/3> <PICT:0876590/III/4> casing.  The backs of books B are passed across that part of disc 56 which protrudes from the casing and receive therefrom a layer of melted adhesive, which is subsequently spread by rotating brush 66.  The thickness of the applied layer is controlled by the adjustable doctor roller 120, and any adhesive not applied to the books is returned to the casing and the passage 94 via gear pump 172.  When cement is not being removed from the exposed part of disc 56, the consequent increase in pressure at the point 162 operates a pressure-sensitive device connected thereto by a passage, which device operates an electric switch controlling the supply of energy to a solenoid 232 which in turn controls the separable clutch 256, 257 in the feeding device through lever 244. The supply of solid adhesive is thus stopped when no molten adhesive is being removed from the disc.  In another embodiment, Figs. 9 and 12, the machine is very similar to that described in the second embodiment of Specification 834,567, having a separate feeding unit 314, melting unit 310 and applying unit 312, the latter being provided with a vane 432 which is normally spring-urged towards the position in which it is shown in the Figure, but which is forced to the other side of slot 428 when, because of non-removal of melted cement by workpieces W, the melted cement accumulates in recess 360 and attempts to escape via passage 364 and the space between the vane and applying disc 350. This movement is used to operate a micro-switch which energises solenoid 444, which by means of link 496 and toggle 490, 492 operates jaws 478, 484 so as to grip the rod of thermoplastic cement R and prevent its being fed into the feeding unit 314.

Title: Process for producing methylene diamines
Filed: 1963-07-05
Abstract: A process for the preparation of methylene dianilines comprises reacting formaldehyde with a salt of aniline or a salt of substituted aniline wherein the amount of acid used in the preparation of salt is one acid equivalent or less per mole of formaldehyde.  The acid may be sulphuric, hydrochloric, perchloric or acetic. In an example 0.5 moles of HCl are introduced into 3 moles of aniline to produce aniline chloride when aqueous formaldehyde is added and the mixture heated at 95 degrees for 2 1/2 hours, and after neutralisation and washing the organic layer is recovered the methylene dianiline separated by distillation.  In another example 0.25 moles of hydrochloric acid are introduced in 3 moles of o-toluidine and the mixture treated with aqueous formaldehyde. After neutralisation and washing 3,31-dimethyl-4,41-diamino diphenyl methane is recovered by distillation under vacuum.

Purifying saccharine liquids. - In purifying aqueous solutions a solution of a lyophyl colloid or a substance which will form a lyophyl colloid is added to the liquid and a, coarsely dispersed precipitate is then produced by the addition of an acid and a base, the operation being conducted at a suitable temperature and hydrogen-ion concentration, so that the colloid is precipitated and can be separated, with colouring matters and other impurities, by filtration or decantation. Albumen, starch, amylum and silica are suitable colloids. The coarse precipitate may be formed by adding successively a base and an acid. In one example albumen is added to raw cane juice, which is then carbonated by means of lime and carbonic acid. In a second example, water-glass is added to diluted cane-sugar molasses, which is then carbonated with lime and carbonic acid. Magnesia, baryta or aluminium, oxide may be used instead of lime and sulphurous or phosphoric acid instead of carbonic acid.

Patent GB-436692-A (GB)
Title: Improvements in and relating to the production of aminonitriles
IPC: C07C255/24
Filed: 1934-09-21
Abstract: Aminonitriles are prepared from oxynitriles by the action of ammonia either as liquid ammonia or as an aqueous or alcoholic solution which contains more ammonia than a solution saturated at atmospheric pressure and a temperature above 0 DEG  C., in a closed vessel.  A preferred method of obtaining oxyacetonitrile is to act on liquid hydrocyanic acid with an aqueous 40 per cent solution of formal dehyde.  With material prepared thus, it is only necessary to saturate with gaseous ammonia at so low a temperature that the ammonia liquifies.  The reaction is preferably conducted at room temperature or slightly higher.  The removal of excess ammonia after the reaction is over is effected in such a manner that only small quantities at a time are freed from ammonia preferably in a passage apparatus, such as a heated tube.  The tube may be kept under vacuum or a current of moderately heated air passed through the apparatus. In examples (1) 375 grams of ammonia at -30 DEG C., are mixed with 125 grams alcohol and 255 grams of 90 per cent oxyaceto-nitrile added, and allowed to stand 36 hours at room temperature.  If the hydrochloride of glycerine ether is to be prepared, the solution of amino-acetonitrile after removal of ammonia is passed into strong alcoholic hydrochloric acid.  (2) an ammoniacal solution of lucine nitrile is obtained by the reaction of oxy-iso-caproic nitrile with liquid ammonia in an autoclave.  The ammonia is then removed in a through flow apparatus.  A description of the passage apparatus used to remove excess ammonia is given.
