Title: Monosulfonamide derivatives of resorcinol
IPC: G03C1/58
Filed: 1948-11-16
Abstract: Monosulphonamides of resorcinol are obtained by treating ammonium, alkaline earth and alkali metal salts of resorcinol 4- or 5-sulphonic acid with benzene sulphonyl chloride to give the corresponding dibenzene-sulphonic ester, followed by halogenating with an agent such as phosphorus oxychloride to the corresponding sulphonyl halide and reacting this compound with an amine followed by alkaline hydrolysis of the benzene sulphonyl groups.  Products specified include the resorcinol monosulphonamide derived from aniline, ammonia, morpholine, n-butylamine, and ethylene diamine, whose preparations are described; and sulphonamides in which one or both the Hs may be substituted by alkyl, hydroxyalkyl, aminoalkyl, polyhydroxyalkyl, alkoxyalkyl, and araliphatic radicals including alkoxy, alkyl and halogen substituents; and by aromatic and chlorinated, brominated and fluorinated, carboxylated, sulphonated, and amino-aromatic; heterocyclic, and alicyclic radicals.

Title: Improvements in and relating to pavements
IPC: E01C7/18
Filed: 1926-02-27
Abstract: 276,538. Armstrong, J. J. V., (Janin, A.). Feb. 27, 1926. Macadamized roads.-A broken stone, gravel, slag or macadamized road comprises a surface layer b of irregular shaped aggregate, the surface voids of which are filled with a bituminous top dressing c formed of aggregate of sand size the fragments of' which are coated with a thin cementitious film of bitumen having a consistency between 30 and 125 points of penetration as tested by the Dow machine, the film leaving the fragments discrete so that they fall apart into the surface voids without adding a separate layer to destroy the non-skid texture of the stone. The preferred top-dressing is that described in Specification 275,280. The aggregate of the surface layer, which can be handled at atmospheric temperature, is preferably coated first with a light, partly volatile, liquefier such as paraffin, naphtha or petrol which acts as a flux to a second coating of heavy bitumen. Fine material matter such as lime may be included as a filler. The surface layer may be placed on one or more layers a of partly or fully compacted bituminized aggregate, each layer being of finer gauge than the one beneath and interlocking therewith. The partly compacted layers may be fully compacted together in one operation.

Title: Improvements in or relating to time-base circuits for magnetic beam deflection
Inventor: GLAISHER EDWARD JAMES
IPC: H03K6/04
Filed: 1959-09-02
Abstract: 857,998. Valve sawtooth generator circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 2, 1959, No. 29956/59. Class 40(6). In a line time base generator of the type in which a driver valve feeds deflection coils through an output transformer, a capacitor is connected in series with the deflection coils and the transformer and the voltage across the capacitor is added to the D.C. voltage applied to the screen grid of the driver valve so that the screen voltage is higher at the ends of the scan than at the centre. In Fig. 2 the driver V1 feeds deflection coils Ld through an auto transformer, the circuit being provided with a damping diode V2 a boost capacitor Cb and a capacitor Cs in series with the deflection coils. A voltage is developed across the latter capacitor of parabolic form so that the waveform produced by the deflection coils is S-shaped to compensate for the flatness of the face of the tube. The capacitor voltage is also added to the screen grid voltage for the driver valve so that the screen voltage and dissipation is lowered during the middle part of the scan. The screens current flows through the upper part of the auto transformer winding and the deflection coils thus reducing the flux in the core and providing a field in the deflection coils which helps to centre the picture. The anode of the diode of V2 could alternatively be connected to the lower terminal of the capacitor Cs. It is stated that the flyback could intrude into the first part of the television picture signal period and the sawtooth produced could be shaped such that the first part of the picture is folded over, to reduce the load on the driver valve.

Title: A process for the separation of protein antigens from protein mixtures and the production of antisera therefor
IPC: C07K16/00
Filed: 1961-08-22
Abstract: One or more protein antigens are separated from a first aqueous solution of proteins by injecting the solution into an animal in which the protein antigen(s) elicit antibody response and obtaining therefrom an antiserum, adding to the antiserum a second solution of proteins identical with the first except that the protein antigen(s) to be separated from the first solution is/are absent to precipitate or render permanently soluble all of the protein-antigen complexes common to both solutions and removing the precipitated material to leave the specific antibody or antibodies for the protein antigen(s) to be separated as the only precipitable antibody material remaining in the antiserum, adding the first solution of proteins thereto to precipitate the protein antigen-antibody complexes containing the protein(s) which is/are present only in the first solution, coagulating the precipitated complex(es), exposing the coagulated complex(es) to the first protein solution whereby more protein antigen specific to the antibody present is absorbed on to the coagulated complex, separating the complex and acidifying to free the absorbed protein antigen and separating a solution thereof from the coagulated antibody-protein antigen complex(es).  The separated protein may then be used to produce an antiserum in the usual way. A specific example describes the separation of ovalbumin from a mixture of ovalbumin and normal dog serum.ALSO:One or more protein antigens are separated from a first aqueous solution of proteins by injecting the solution into an animal in which the protein antigen(s) elicit antibody response and obtaining therefrom an antiserum, adding to the antiserum a second solution of proteins identical with the first except that the protein antigen(s) to be separated from the first solution is/are absent to precipitate or render permanently soluble all of the protein-antigen complexes common to both solutions and removing the precipitated material to leave the specific antibody or antibodies for the protein antigen(s) to be separated as the only precipitable antibody material remaining in the anti-serum, adding the first solution of proteins thereto to precipitate the protein antigen-antibody complexes containing the protein(s) which is/are present only in the first solution, coagulating the precipitated complex(es), exposing the coagulated complex(es) to the first protein solution whereby more protein antigen specific to the antibody present is absorbed on to the coagulated complex, separating the complex and acidifying to free the absorbed protein antigen and separating a solution thereof from the coagulated antibody-protein antigen complex(es).

Apparatus for use in electrical conductivity tests on a solid material which cakes in storage comprises a mould for a sample of the material, a fluid pressure operated device for applying pressure to the sample, a flexible diaphragm seal 4 between the mould and the device to prevent gain or loss of solvent from the sample and means to measure the electrical conductivity of the compressed sample. Pressure is applied by a pneumatic piston 9, acting through a rod 10, a plunger 12 and a plate 3; and the conductivity is measured, using alternating current, between the top and bottom plates of the mould. Friction is reduced by greasing the mould walls and lining them with polythene or polytetrafluorethylene, by embodying a flexible diaphragm between piston 9 and its cylinder 13 and by forming the bush 15 for the rod of co-sintered polytetrafluorethylene and bronze. The plate 3 and the plug 6 forming the mould bottom may be removed and the force required for the plunger to push out a cylinder of the caked material measured, to give an indication of caking strength.
