March 13, 1935, No. 7773. [Class 145 (i)] [See also Group VIII] In a machine adapted to cut out from sheet material and then to bevel marginally blanks such as cores for rubber heels as described in Specification 253,510, [Class 17 (ii)], (a) the die carries the blanks to the position to be bevelled ; (b) for the bevelling operation, the blanks are partly ejected from but held in the die ; (c) during the bevelling operation, relative movement occurs between the blank and the operating tool in the direction of the thickness of the blank. A strip of material, e.g. plywood is placed on a table 20, Fig. 1, between adjustable side guides 42 and is pushed forward by an adjustable reciprocating feed slide 22 to engage between a pair of toothed feed rolls 24, Fig. 3, mounted on vertical studs 68 carried by a vertically reciprocating head 26 which cooperates with a die 30. The feed rolls 24 are adjustable laterally by a screw 140 and nut 142, 144, mechanism acting to move against a spring 150, sleeves 146, 148 on brackets 80 carrying the feed roll driving mechanism which includes a pawl 104 and ratchet wheel 102 to obtain an adjustable intermittent feed. Upper and lower guide plates 118, 120 are also provided. The die 30, Fig. 6, is provided with punches 162 to make holes 16, an adjustable stamp 172 for marking the lower side of the blank and a spring-retracted ejecting plunger 34.

Relates to an apparatus for forming and delivering layers of pasty substances, e.g. the cream used in sandwiches, and comprising a rotary drum formed with a number of equallyspaced radial cylindrical holes, each provided with a slidable piston and adapted to be brought, by intermittent rotation of the drum, to the receiving and delivery positions. The cream is supplied from a hopper 34, the mouth of which closely contacts the periphery of the drum 11 rotatable on a shaft 12 by a Geneva mechanism. The outer surfaces of the pistons 6, which slide in the holes, conform to the shape of the surface of the drum, and each piston is provided with a pin, the outer ends of which carry rollers 21 engageable in grooves in arms 23, 24 or in tracks 49 when a hole reaches the receiving position adjacent the hopper. The piston moves inwards to allow a thick layer of cream to be deposited; the arms 23, under the influence of a cam 28, then raise the piston to compress the layer to the desired thickness. During the next movement of the drum, the piston is held by the engagement of the rollers 21 in the tracks 49. At the end of the following movement, the piston is moved to expel the cream by the arms 24 under the influence of a cam 29, or further cam 46 acting to swing a scraper 37 across the face of the piston.

Abstract: 750,412. Generating combustion products under pressure. SOLAR AIRCRAFT CO. March 23, 1953, No. 7987/53. Class 51(1). [Also in Group XXVI] In a jet propulsion system, exhaust gases from a reciprocating internal combustion engine 11 which contain combustible components are fed to the inlet 21 of a mixing and combustion device. Air is supplied by ram pressure through the duct 29 and mixes with the exhaust gases flowing through the duct 26, in the mixing section within the duct 31. A perforated pipe 27 open at both ends is disposed vertically at the outlet end of the duct 26 to assist the mixing. A mixture of fuel and air is tapped from the engine supercharger 13 and is fed through the pipe 39 into an annular manifold 33. The fuel and air mixture issues through orifices 41 into a stabilised combustion zone 42 where it is ignited by a spark plug 43 to form a stabilised pilot flame which causes ignition of the exhaust gas and air mixture issuing from the mixing section 31 into the main combustion zone within the duct 24. The gases issue through a tail pipe 17 to a propulsion nozzle. In a second embodiment, Fig. 5, the engine exhaust gases are fed through a duct 55 to an annular passage 56 around the duct 50 through which air is supplied under ram pressure. The gases and air mix in the duct 53 and issue into the duct 58 where they are ignited by a stabilised pilot flame formed as in the first embodiment.

A cross-linked foamed reactive copolymer latex is made by emulsion polymerizing, in an aqueous medium, at least two ethylenically unsaturated copolymerizable monomers, the monomers having a minor proportion of units having reactive groups and incorporating into the resulting latex prior to curing and drying of the foam, a metal compound as an inorganic crosslinking agent for said reactive groups, the metal being one which forms a complex compound of the Werner type. In examples the latex was prepared by polymerizing styrene, itaconic acid and 1,3-butadiene in an aq. mixture of sodium dodecyl benzene sulphonate, potassium persulphate and tert.-mercaptans; the latex was then compounded with an alkylated bis-phenol, lauroyl sodium sulphate, china clay and a silicone, mixed with zinc oxide or ammonium zirconyl bi-carbonate and foamed, gelled and cured. The latex may also be compounded with etherified starch or sodium alginate to improve foaming.

Title: A process for the catalytic desulphurisation of hydrocarbon oils
Inventor: DOUWES CORNELIS THOMAS
IPC: C07C7/148
Filed: 1960-03-09
Abstract: Sulphur-containing hydrocarbon oils are desulphurized by contact with a hydrogenating/dehydrogenating catalyst containing one or more alkali metal compounds at temperatures from 250 DEG -450 DEG C. in the presence of steam.  Additionally the catalyst may contain one or more metals from Groups V-VIII, e.g. chromium, tungsten, molybdenum, manganese, iron, cobalt and nickel either in combination with each other, e.g. cobalt thiomolybdate, or with oxygen or sulphur. Specified alkali metal compounds are lithium, sodium and potassium carbonate, hydroxide, formate and acetate. The catalyst may have for supports either alumina or silica-alumina.  The catalyst may be used in fixed, fluidized or suspended condition and contact between hydrocarbon oils and catalyst may be maintained continuously.  The catalyst may be used as particles of 30 mesh or smaller and contact between the oils and the catalyst may be effected at atmospheric pressure up to 75 atmospheres absolute or higher.  The catalyst may be sulphided in known manner, e.g. by passing thereover a mixture of hydrogen and hydrogen sulphide, carbon disulphide or butylmercaptan. Catalyst preparation may be effected by fine milling a cobalt-molybdenum-alumina catalyst and mixing the resulting powder with anhydrous soda.  Thereafter a lubricant such as stearic acid or graphite may be added and the whole compressed into pellets, calcined and sulphided.  Examples describe comparatively the catalytic desulphurization of xylene and kerosine.  Other coal tar fractions, gasolines, gas oils and residual oils may be similarly desulphurized according to the invention.  Specification 657,521 is referred to.
