Title: Apparatus for measuring the concentration of suspended substances in a flowing liquid
IPC: G01N15/14
Filed: 1975-08-27
Abstract: 1525624 Measuring particles photo-electrically SVENSKA TRAFORSKNINGSINSTITUTET 27Aug 1975 [28 Aug 1974] 35393/75 Heading G1A To measure the concentration of particles of different sizes in a flowing liquid, the liquid is illuminated and the scattered light is detected to produce a D.C. signal and a signal representing the number of times the scattered light exceeds a given amplitude. The D.C. signal is a measure of the concentration of small particles while the other signal is a measure of the concentration of large ones; intermediate sizes affect both signals and calibration with known liquids is necessary. In Fig. 1 the liquid in tube 3 is illuminated by sources 1 and/or 1', and the scattered light is collected by detectors 4, 5 which respectively measure the impulses due to large particles and the D.C. level due to smaller ones; the signals are processed according to calibration constants at 6 to give the total particle concentration as well as the concentration of large and small particles. The sources 1, 1' may be used alternately to provide different wavelengths, or may be spaced around the tube 3 to illuminate it from different angles. A further detector 7 measures the light transmitted by the liquid and controls the source brightness to eliminate the effects of changes in absorption in the liquid. The functions of the two scattered light detectors may be carried out by a single detector, Fig. 2 (not shown). The apparatus may be used to monitor fine and first-rate fibres in the waste of a wood processing plant.

A bolster RQ is suppori-ted by swing links RM, QN pivoted to a railway vehicle bogie frame at M and N, and a tension spring S pivotally connected at G to t h e bogie frame is arranged to exert on the bolster a force PL which increases from zero with lateral displacement of the bolster from a centtral position Q<SP>1</SP>R<SP>1</SP> and opposes s the restoring force F arising due to load on the bolster acting through the links, on such displacement. The end of the spring S remote from the pivot G is connected to one end of a lever UH pivoted at its other end to the bogie frame at H, the lever being connected to the bolster by a link UT. When the bolster is in its central position the points G, H, and U and the spring are aligned and no horizontal force is exerted on the bolster. In a modification the spring is a compression spring. According to the Provisional Specification, the tension spring may be horizontally arranged and connected to the bolster through a bell crank lever and link.

Title: Polysaccharide esters
Inventor: LEMMERLING JOSE THERESE
IPC: C08B11/20
Filed: 1961-10-02
Abstract: A m- or p-sulphobenzoyl ester of a polysaccharide or a polysaccharide derivative containing free hydroxyl groups is made by reaction of the polysaccharide, in presence of a tertiary organic base, with a m- or p-halogenosulphonylbenzoic acid.  The benzene nucleus of the acid may be substituted by groups inert to reactants and reaction products, e.g. nitro or alkyl groups, or halogen atoms.  The polysaccharide may be e.g. cellulose, starch, amylose, amylopectin, alginic acid and partially esterified and/or etherified derivatives thereof, e.g. cellulose acetate, ethyl-, benzyl- and hydroxyethyl celluloses. Specified acids are m- and p-chlorosulphonyl benzoic acids. Specified tertiary organic bases are anhydrous pyridine, dimethyl-and diethyl aniline, trimethylamine and triphenylamine. Reaction is carried out at room temperature for e.g. 24 hours or at 60-80 DEG  C. for e.g. 4-6 hours, the product is a salt of the tertiary base, and may be converted to free acid ester by known methods.  In a typical example, hydroxyethyl cellulose (D.S. 0.85) and p-chlorosulphonyl benzoic acid are added to anhydrous pyridine.  After reaction at 80 DEG  C. for 24 hours, hydroxyethyl cellulose-p-sulphobenzoate is precipitated in dilute HCl.  The esters, as free sulphonic acids or as alkali metal, ammonium or tertiary base salts, are used as binding and thickening agents in photographic materials (see Division G3).

Abstract: 1,167,820. Coating apparatus. STABILAG ENG. Ltd. 26 July, 1968, No. 35731/68 Addition to 1135101. Heading B2L. [Also in Divisions Dl and F2] In the apparatus of the parent specification, the applicator nozzle, adapted to open when the pressure of hot melt adhesive supplied thereto is raised above a preset valve, is modified by the provision of an inlet for the selective admission of pressure air to prevent opening of the nozzle in response to said rise in pressure. As shown, a cylinder 7 contains a piston 5 having a stem 4, one end of which carries a tungsten carbide pad 3 adapted to close a straight-sided applicator orifice 2, and the other end of which is connected to a piston 8 in a cylinder 9. Admission of compressed air to the latter via an inlet 10 normally serves to close orifice 2 until the pressure of the circulating adhesive rises above the preset value. An increase of pressure in cylinder 9 serves to prevent opening of orifice 2. The length of the orifice is equal to or greater than four times its diameter. In an alternative construction, orifice 2 is initially closed by spring pressure. as. in the parent Specification.
