Title: Process for the manufacture of finely divided insoluble and infusible solids of large surface area
IPC: A01N25/10
Filed: 1964-08-04
Abstract: Finely-divided, insoluble, infusible solid substances having a specific surface area greater than 10 square metres per gram are obtained by forming from an aqueous solution of melamine and formaldehyde in a molar ratio of 1 to 1.5-6 at a pH of 0-6 and a temperature of 0-140 DEG  C. in the presence of one or more surface-active substances a solid phase, which is freed from inorganic salts, dried at 30-160 DEG  C., and comminuted to an average particle size of less than 5m .  The solid phase is preferably formed from a precondensate prepared at a pH of 5-10, in the presence of a buffer substance, e.g. potassium hydrogen phthalate, an ammonium or monoethanolamine phosphate or a neutral ammonium tartrate, and one or more surface-active substances, e.g. quaternary ammonium salts, fatty alcohol sulphonates, alkylarylsulphonates, salts of sulphosuccinic acid esters, monoglyceride sulphates or polyalkylene ethers or tragacanth. The dehydration may be by spray-drying, or, preferably, by azeotropic distillation using a hydrocarbon or halohydrocarbon boiling at 30-160 DEG  C., e.g. benzene, toluene, xylene, methylene, chloride, chloroform, carbon tetrachloride, 1,2-dichlorethane or trichlorethylene.  The comminution may be by ball mill, roller mill, hammer mill or air jet mill, or may be performed as a wet grinding operation before, e.g. spray-drying. The powder may be used as a filler or reinforcing agent for rubber or synthetic resins. In Examples 18 and 24 rubber is milled with ZnO, S, stearic acid, a vulcanization accelerator and a powder of the invention (and in Example 24 with a plasticizer and diethylene glycol also).  In Examples 25 and 26 a P.V.C. resin is milled with dioctyl phthalate, Ba and Cd laurates and a powder of the invention, then gelled to give a foil.  In Example 27 mat rayon fibres are prepared from a dope into which has been incorporated a suspension of 1m  particles of the invention.  These powders may also be used as vehicles and bases for pesticide and cosmetic powders and pastes, as supports for ion exchange resins, and as fillers for paper.

Abstract: 801,443. Transistors. STANDARD TELE. PHONES & CABLES, Ltd. Sept. 5,1956, No. 31526/57. Divided out of 801,442. Class 37. A method of making a fused junction transistor comprises three stages; heating a pellet of activator material characteristic of one conductivity type in a jig on one face of a body of semiconductor of the opposite conductivity type to wet the body, heating a similar pellet located in a jig on a second face of the body to wet the body, and then heating the assembly to a higher temperature which is maintained for a time before slowly cooling to form recrystallized zones of the one conductivity type on the body. In the embodiment a slice 1 of 1 ohm cm. N-type Ge, the surfaces of which lie in III crystallographic planes is placed as shown (Fig. 1) in a jig 10, 12 which is made of graphite at least where it contacts the Ge, and an indium blob 14 placed on the slice through aperture 13. The assembly is heated to 340-380 ‹ C. in 15 minutes in hydrogen, held at that temperature for 10 minutes and then cooled to room temperature. The slice is inverted, a second indium blob placed on it as before opposite the first blob and the assembly heated as before. The temperature is then raised further in 15 minutes to 475- 590‹ C., held for 10 minutes and afterwards lowered at a rate of 20‹ C./minute to 350‹ C. After cooling to room temperature the device is removed from the jig and a base contact 7 (Fig. 7) in the form of an open circle of goldplated molybdenum flash-plated with antimony fused to the body by passing a current through it as described in Specification 801,442, from which the subject-matter of the present Specification has been divided. Leads 4, 5 of platinum or other noble metal are then applied by pressing them on to the indium beads 2, 3 while current sufficient to melt the beads is passed between them, cooling, applying a flux to the junction between the beads and leads, and then passing a further current to fuse the beads to the leads. This method of attaching the leads forms the subject-matter of Specification 801,444 which has been divided from Specification 801,442. In an alternative embodiment lead or lead antimony beads are alloyed to a P-type Ge body to form an NPN transistor.

Abstract: 408,176. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., Aden Road, Ponders End, Middlesex. Nov. 14, 1933, No. 31693. Convention date, Aug. 17. [Class 28 (ii).] In a slicing-machine, the pusher-plate 54 is mounted on a pivot 48 so that it may be used in two vertical positions, one on each side of the pivot, and in the inclined position in which it acts somewhat as a clamp. The plate 54 may have spikes 58 on one or both sides, and prongs 59 on one or both of the upper and lower edges. A pin 56 abuts against shoulders 57 which limit the angular movements about the pivot 48. A pin 64 contacts, as the pusher approaches the slicing plane X-X, with the face 62, 63 of a stop member 60 which is shaped to check the feed to prevent the pusher from fouling the knife, irrespective of the inclination. The feed is by spring or weight means, by hand or by gravity, and the pusher is pivoted to the upstanding portion 46 of a slide member 43 mounted for movement on a guide 41. The substance support 17, over which the substance slides, has an out-turned flange 45 which engages between a washer 52 on the pivot bolt 48 and the head of a bolt 47, so that the flange 45 acts as a guide complementary to the guide 41. When spring feed-means are used, the spring 69 is coiled around pulleys 66, 67 and is hooked over lugs 71, the great length of the spring producing a more uniform feed effort. The substance-engager is pulled back by the handle 72 which is engaged in the rearward position by a releasable pivoted latch 74, which has a cam face 76 engageable by the handle. A pin 77 engaging a hole 78 maintains the latch in a position to be engaged by the handle. The knife and reciprocating carriage are reciprocated by the means described in Specification 408,177.
