Title: Method of manufacturing refractory basic bricks
IPC: C04B38/02
Filed: 1952-05-28
Abstract: A basic refractory insulating brick having a porosity greater than 35 per cent. by volume is obtained by pressing and thereafter firing a mixture containing a foundation material preponderantly as grains not exceeding 2 mms. and which by firing forms the fundamental refractory structure of the brick, and a carbonate preponderantly as grains between 1.7 and 6 mms. and which has a CO2 content of about 50 per cent. by weight and which by the firing becomes a refractory oxide and which is present in sufficient amount to give the desired porosity.  Specified foundation materials are chromite, magnesia, calcined chalk, zirconia, titania, thoria, and old brick rubble, whilst the carbonate includes magnesite, dolomite (which may be stabilized) and limestone.  Temporary binders, e.g. sulphite liquor, can be added before pressing, and for greater porosity in the finished brick combustible materials e.g. tar, can be added. Magnesium sulphate may also be used as a binder.  Specification 657,498 is referred to.

Patent GB-485336-A (GB)
Title: The dyeing of cellulose esters and ethers
IPC: D06P3/34
Filed: 1937-05-14
Abstract: Cellulose esters and ethers are dyed by means of water-insoluble azo dyestuffs of the general formula Alkyl-CO-R-N=N-A where R is a radicle of the benzene series and A is the radicle of a coupling component, which dyestuffs contain no free carboxylic or sulphonic acid groups, the dyeing process being performed with the addition of a dispersing agent. The dyestuffs are obtained by coupling the diazo compounds of aminoketones of the general formula Alkyl-CO-R-NH2 with coupling components, e.g. aromatic amines, phenols, pyrazolones, hydrogenated quinolines and substitution products thereof, neither component containing free carboxylic or sulphonic acid groups. In examples: (1) the dyestuff 4 - aminoacetophenone --> di-(hydroxyethyl)-m-toluidine is mixed with a dispersing agent prepared according to Specification 251,019, [Class 2 (iii)], a dye bath is made up with water and Marseille soap, and acetate artificial silk is dyed therefrom in reddish-orange shades; the analogous dyestuff from diethylaniline similarly yields orange shades; (2) acetate artificial silk is similarly dyed reddish-yellow shades by means of the dyestuffs 3-amino-acetophenone --> N - di - (hydroxyethyl) - 3 - chloraniline or hydroxyethylmethylaniline; (3) the dyestuffs 3 - chloro - 4 - aminoacetophenone --> dimethylaniline or di - (hydroxyethyl) - m - toluidine similarly dye acetate artificial silk reddish orange and yellowish scarlet shades respectively.  The Specification as open to inspection under Sect. 91 refers also to the printing of cellulose esters and ethers.  This subject-matter does not appear in the Specification as accepted.

Abstract: 807,585. Making spring cycle clips; angular bending. SHELTONS (NORTHAMPTON) Ltd. May 7, 1957 [May 9, 1956], No. 14424/56. Drawings to Specification. Classes 83 (2) and 83 (4). [Also in Group XXV] In the manufacture of an arcuate spring band having a covering of flexible non-metallic material such as polyvinyl chloride the end portions of the spring are weakened to an extent sufficient to enable such portions when enclosed by the covering material to be formed into a fold or roll without damaging the covering material. A suitable strip of spring steel in an annealed condition has its end portions weakened by grinding to reduce their thickness or by notching, drilling or forming channels therein and the strip is then bent to the desired arcuate shape with the two end portions bent outwardly. The arcuate portion is then hardened and tempered if necessary and the covering material is applied so that it overlaps the end portions. The overlapping end portions of the covering material are closed by hot pinching or by a suitable solution and the covered end portions of the spring are then folded or rolled outwardly or inwardly so as to provide smooth and rounded ends to the band.

Title: Improvements in or relating to Pressure Exchangers
Inventor: WILLIAMSON DOUGLAS HERBERT
IPC: F02C3/02
Filed: 1967-03-30
Abstract: 1,181,813. Pressure exchangers; gas turbine engines. ROLLS-ROYCE Ltd. March 6, 1968 [March 30, 1967], No.14426/67. Headings F1G and F1N. A pressure exchanger rotor 15, 16 is rotatably mounted between a fixed end plate 25 and an endplate 31 capable of axial movement in order to accommodate expansion of the rotor, the movement being permitted by flexure of annular diaphragms 40, 41, 42 fixed at their outer peripheries to a casing 28, 29, 52 and connected at their inner peripheries to the end-plate 31. To reduce the pressure forces tending to separate the end-plates and taken by bearings 23 supporting the rotor, the chambers 45, 44, 51 between the diaphragms are maintained at different pressures. The chamber 45 is vented to atmosphere through apertures 49; the chamber 44 is pressurized by low-pressure air leaking through the end clearance 32 between the rotor and the movable end-plate 31 and communicated through a duct 34; and the chamber 51 is pressurized by high-pressure air supplied directly from an inlet duct 13. A cylindrical axially flexible seal 46, 47 extends from the end-plate 25 into abutment with the axially movable end-plate 31. In alternative embodiments, Figs. 3 and 4 (not shown) the movable end-plate is supported by only two diaphragms which form a single pressure chamber therebetween. Fig. 5 shows such an alternative pressure exchanger 84 incorporated in a gas turbine engine and comprising diaphragms 61, 62 defining a pressure chamber therebetween. The engine has a compressor 81 having three axial stages and a centrifugal stage. Air enters the compressor through inlets 80 and is delivered through ducts 83 to the pressure exchanger. The air is compressed in the exchanger and is then supplied through ducts 85 to a combustion chamber 86 whose exhaust gases are fed to an outlet 87 leading back to the exchanger. These exhaust gases compress the incoming air from the compressor. Thereafter they pass out through ducts 88 to a turbine 89 driving the compressor 81 and a further turbine 90 driving an output gear-box 91, before being discharged through a jet-pipe (not shown). The pressure exchanger shown in Fig.1 may replace the exchanger forming part of the gas turbine engine described in Specification 1,104,529. Reference has been directed by the Comptroller to Specification 1,104, 529.

In a method of producing, from a batch of thermistor elements, a plurality of thermistor units having substantially identical resistance/ temperature characteristics over a predetermined temperature range, each unit comprising n interconnected thermistor elements, the resistance of each element in the batch at each end of the predetermined temperature range is measured and the average resistance of the elements at each end of the range is determined; groups of n elements each are then connected to form the thermistor units, the elements of each group being selected so that the total resistance of each unit at each end of the range is, within a predetermined tolerance, equal to the corresponding batch average resistance multiplied by a factor determined by the value of n and the method of interconnection of the elements. For example, when the elements are connected in series, the factor is equal to n; with parallel connected elements the 1 factor is -. Series-parallel arrangements may n be used. In modifications, the resistances of the elements are measured at two temperatures within the predetermined range other than those at the ends of the range, and characteristic batch resistances other than the average resistances at the measured temperatures may be used. The thermistor materials-oxides of manganese, nickel, cobalt, chromium, uranium, iron, magnesium, zirconium and cerium are mentioned-may be powdered and sintered to form batches of elements, conductive leads or surfaces being simultaneously or subsequently added to the elements, which may be coated, capsuled, or otherwise sealed individually or in groups.
