Patent GB-420756-A (GB)
Title: Improvements in the manufacture of cement
IPC: C04B7/36
Filed: 1933-06-07
Abstract: A process for the treatment of cement clinker comprises grinding the clinker in the usual way to the normal degree of fineness, separating the ground clinker into two or more portions, and then adjusting the granular and chemical characteristics of each fraction to produce two cements so that each has a setting time complying with the standard specification.  The setting time of the fine fraction requires to be retarded, and this is effected by the addition of calcium sulphate or calcium chloride either before or after grinding.  The setting time of the coarse fraction requires to be accelerated and this is effected either by subjecting to a further grinding, or by the addition of the required amount of fine material.  The separation of the original cement into two portions is preferably effected in an air separator.  In an example, a normal cement was separated into two fractions, the finer portion consisting essentially of grains under 30 microns constituting 20 per cent of the total amount of the cement.  5,5 per cent of ground gypsum was added to the fine portion and a high grade of rapid hardening cement was obtained. To the coarse portion of which 45 per cent consisted of grains of less than 30 microns, 3 per cent of ground gypsum was added.  This gives a slow setting cement which after a renewed grinding became of similar quality to a normal Portland cement.

In a convector space heater in which a pipe 2 carrying heating fluid extends through corresponding apertures in a plurality of transverse fin elements frictionally held to the pipe by tabs 3 formed around the periphery of each said aperture, each fin element is of channel crosssection comprising side walls 5 joined by a base portion, the latter having a central zone 4 (shown  as V-shaped) located between outer zones 1, the latter zones lying in a common plane and the zone 4 being displaced from said plane. By this anangement it is said, the marginal portion of the base of the fin section, may be displaced (e.g. accidentally during service) without causing the tabs 3 to lose contact with the pipe 2. As shown, the side walls 5 of the channels are so formed at 6, 7 that adjacent fins mutually support each other, the fin members together forming ducts through which flows convection air heated by the pipe 2.

Abstract: 640,338. Cooking-ranges. SVENSKA AKTIEBOLAGET GASACCUMULATOR. June 18, 1948, No. 16436. Convention date, June 21, 1947. [Class 126] In a cooking stove having a heatinsulated combustion chamber with two combustion zones one above the other so that fuel in the upper zone may descend to the lower, the fuel between the two zones is held out of contact with the walls of the combustion chamber which emit heat to the heat consumption points. The upper combustion zone is formed in fuel on a grate 2 and has a thermostatically controlled air supply opening 19, the heat generated being mainly utilised for heating a hot plate 8. An opening 5 provided in the grate 2 is fitted with a tubular grate 6 through which fuel passes from the upper to the lower combustion zone, the fuel for which rests on a grate 3. Air is supplied to the lower combustion zone through an opening 23 controlled by a thermostatically controlled damper 24. Fuel is held away from the wall 7 of the combustion chamber 1 intermediate the two combustion zones by the tubular grate 6. Heat from the lower combustion zone reaches the wall 7 of the combustion chamber 1 and is transmitted to air which circulates round an oven 16. The grate 2 and tubular grate 6 may be replaced by a conical grate (Fig. 2, not shown). Depending pins are provided on the hot plate 8 for limiting the height of the fuel column and a grid 12 prevents the access of fuel to a flue 13 beneath the hot plate 8.

Abstract: 1,132,877. Cycle &c. vehicles. E. QUEDREUX. 15 April, 1966 [27 April, 1965], No. 16626/66. Heading B7E. A motor or pedal-driven vehicle is illustrated in its pedal drive version and comprises two coaxial wheels 14, 14<SP>1</SP>, substantially circular and cross-connected tubular frames 7, 7<SP>1</SP> also supporting parts 7<SP>4</SP> and 7<SP>5</SP> mounting castor wheels or skids 9, grooved rollers 13 in pairs engaging the wheels 14 and supporting the weight of the frames 7 and the load, and a chain and pedal wheel drive rotating roughened grooved rollers 15 also engaging the wheels 14 but movable and guided in slots against springs (21), Fig. 3 (not shown), to a non-drive position out of engagement with the wheels. When the driver turns the pedals in the direction a the rollers 15 tend to climb up the inner periphery of the wheel and move the centre of gravity G of the driver &c. forwardly of the centre C of the wheels 14. This produces instability in the vehicle and the wheels 14 rotate also in the direction a to move the driver forwardly and return the point G to lie beneath C. By turning a wheel 34 the vehicle may be steered by differentially applying or releasing cable-operated caliper brakes on each wheel 14, see also Figs. 4-6 (not shown). The steering column which is hinged at 31 to the main frame may be pivoted downwardly to pull on the brake cables and apply both brakes simultaneously, and in this position also lift the rollers 15 away from the wheels 14.

Abstract: 591,716. Gas holders; tanks. WIGGINS, J. H. Sept. 4, 1944, No. 16867. [Classes 54 and 69 (i)] In a gas holder or tank of the type comprising a vertically-movable piston member connected to a rigid wall member by a flexible gas-tight element, so as to constitute an extensible side wall portion of the gas space, the gas space X is formed by the gas-tight, stationary side wall A, roof B and bottom constituted by a vertically-movable piston whose peripheral edge is connected to A by a flexible gas-tight element D, the side wall A being supported by the structure E, sufficiently elevated to allow full movement of the piston. The roof is supported mainly by the tubular member F, containing the counterweight 3, connected to the piston structure by cables 1 and the diameter is made gas-tight where the member F passes through the piston by a flexible element D<1> ; the upper end of the supporting member is sealed by the cap 9 and its lower end provided with the gassealed drain device 10. The flexible element D is attached to the side wall so that it is spaced off from the structure E to avoid freezing, either by inwardly offsetting the side wall A (as at A<1>), or by the provision of an angle iron, to the inner surface of which the element is clamped. Condensate collected on the wall A of the gas space is removed by liquid-sealed U tubes 14, which collect it from troughs formed by the diaphragm clamping bars, and the condensate on the roof is preventing from dripping into the diaphragm folds by a vane 17, which directs it on to the upper face of the piston C. The piston cables are balanced with, the counter-weighing mechanism to keep the working pressure constant at about 1/38 in. of water in all positions of the piston.

Abstract: Artificial protein filaments which have been insolubilized by means of formaldehyde in the presence of a strongly acidified saline solution, are treated with a strong aqueous formaldehyde solution having a pH value between 8.6 and 10.4.  The insolubilized filaments are preferably treated in relaxed condition.  In an example, a matured alkaline solution of peanut globulin is spun into a bath containing sulphuric acid and sodium sulphate, stretched, immersed on a swift in a saturated sodium chloride solution, and cut into staple fibre.  The staple fibre is insolubilized in a bath containing sulphuric acid, formaldehyde and sodium chloride, and is then washed, treated with solutions of sodium cetyl sulphate and sodium carbonate, washed again and finally dried.  The fibre has an average strength of 7.7 kgs. per square millimetre.  It is then immersed at room temperature for 40 minutes in 40 per cent formalin containing sufficient sodium hydroxide to give a pH value of 9.6.  After washing and drying, the fibre has a strength of 12 kgs. per square millimetre. Specification 513,910 is referred to.
