Abstract: 277,724. Lennard, T. C. May 21, 1926. Tensioning belts.-Tlie tensioning roller is connected to a reciprocatory fluid-pressure engine in which the is maintained constant or adjusted to vary the position of the roller. The pressure may be controlled automatically by fluctuations in the load. The tensioning roller G is mounted in a member H which can slide in a bed K and is attached to the piston rod f of a compressed air engine E fixed to the bed K. An air compressor N driven either by the driving drum 0, driving motor or roller G supplies air to the cylinder E through a receiver R, control valve C, pipe D, manually-actuated valve P, and flexible pipe d. The stem c, Fig. 3, of the control valve C is conlrolled by an electromagnet 13 in series with the main current supply a to the motor driving the conveyer. When the conveyer is empty, little current is needed to drive it and the valve C is kept closed by the spring s. As the load increases, the driving current, will increase and the valve C will open to allow compressed air to pass to the cylinder E and move the rod f to the right, Fig. 2, thereby increasing the tension of the belt M. The cylinder E is fitted with a vent which allows air to escape at a predetermined rate. The position of the bed K mav. be varied by screws L.. A common compressor N may be used for a number of conveyers. The conveyer may be driven by steam, compressed air, or internal combustion engines, and the valve C controlled bv fluctuations in the load on these engines. The valve C may be dispensed with and the compressor N may be adapted to maintain a constant pressure in the cylinder E. This pressure may be adjusted by the manuallycontrolled valve P.

Patent GB-566444-A (GB)
Title: Improvements in and relating to drilling machines
IPC: B23B45/04
Filed: 1943-08-12
Abstract: 566,444. Grinding and lapping. WHITE, P., and AUTOMOTIVE ENGINEERING CO., Ltd. Aug. 12, 1943, No. 13083. [Class 60] [Also in Group XXII] Machines or heads for drilling holes of the diameter of a few mils are turbine driven and the pressure on one or both sides of the turbine rotor is varied to effect axial feed and retraction. The variation may be produced by a mechanically-actuated valve and this is particularly suitable for causing reciprocation of the spindle when grinding or lapping. The drill spindle 1 journalled in a sleeve 3 extending from the turbine casing 4 carries a rotor 5 having buckets 8 of Pelton-wheel form on each side. A detachable head 11 has an inlet passage 10 leading to supply nozzles 14, 14a. The chamber 6 below the rotor has an exhaust port 17a, 17b and the chamber 6a exhausts at 19, 19a. The ports 17b and 19a are each controlled by grooves in a valve plug 20, the grooves being so arranged that as one port is opened the other is restricted. Pressure is thus caused to build up on the required side of the rotor to effect feed or retraction of the spindle, the axial length of the chamber 4 being sufficient to permit the required stroke. In a modification, the two exhaust ports have preset screwadjusted throttling plungers to determine the pressures, there being an additional exhaust port, for the chamber above the rotor, that can be closed at will by a press-button valve, the setting being such that pressing and releasing the valve causes reciprocation of the spindle, for example, in grinding or lapping.

Abstract: 319,251. I. G. Farbenindustrie, Akt.- Ges. May 7, 1928. Addition to 261,029. Condensation products from dimethylol-thiourea.-In the process of the parent Specification, the dimethylolurea comprising the starting material is replaced by dimethylolthiourea or the products of higher molecular weight resulting therefrom by splitting off water or by mixtures of the foregoing with each other or with dimethylolurea or with the products of higher molecular weight resulting therefrom by splitting off water. The condensation is effected in a considerable quantity of organic solvent, e.g. acetone or monohydric alcohols such as ethyl alcohol, until colloidal compounds are formed in the solution. Lacquers are obtained if the solvents employed are allowed to remain; if evaporated away, resins and glass-like masses remain. As in the parent process, filling materials such as other resins, plasticizers, talcum, diatomaceous earth and plaster of Paris may be added. The products of higher molecular weight from dimethylolthiourea are prepared in the same way as those obtained from dimethylolurea which are described in the parent Specification. According to the example, dimethylolthiourea is first prepared by heating thiourea with trioxymethylene in methyl alcohol with a little caustic potash, and is then suspended with dimethylolurea in methyl alcohol containing a little sodium tetroxalate, and heated to boiling point. The solution, after neutralization and filtration, may be used as a lacquer and can be mixed with solutions of resins or of cellulose esters or ethers. Evaporation of the solvent gives a viscous product which is transformed by heat treatment into a resin. Specification 301,696 also is referred to. Reference has been directed by the Comptroller to Specifications 262,148, 266,752, and 296,361.

Filed: 1927-05-19
Abstract: 272,468. Zierer, A. June 9, 1926, [Convention date]. Bacteria, cultivating; bacteria, preparations for administering.-A modified Yoghurt preparation is obtained by boiling or pasteurizing full or skimmed milk to which sugar has been added, flavouring it, if desired, with fruit essence or fruit juice, and then treating it with a mixture of pure cultures of Yoghurt bacteria (bacterium bulgaricum), micrococcus lactis acidi L÷hnis, and certain specified Torula and Mycoderma yeasts which produce neither alcohol nor carbonic acid. The milk is treated with the cultures at about 30‹ C., and after it has curdled is stored in a refrigerator. The pure cultures are made separately on whey, whey agar, malt extract and agar, or bouillon and agar containing also 3 to 4 per cent of dextrose, and are then transferred in definite proportions to sterile skimmed milk. The mixed culture in milk is re-cultivated daily so as to retain its vigour. The whey medium is prepared by mixing skimmed milk with rennet, cutting up the curd, and filtering through a filter bag and then through paper. The filtrate is boiled, clarified with white of egg, filtered, mixed with 2 per cent of dextrose, lactose, maltose or galactose, and fractionally sterilized. The medium should be slightly acid. A 1 per cent agar medium may be made from the whey medium in the usual manner. The Specification as open to inspection under Sect. 31 (3) (a) states that the bacterium bulgaricum may be replaced by bacillus acidophilus or bacillus bifidus, and describes the preparation of a malt agar medium by steeping malt meal in water, gradually heating to 60‹ C., filtering, diluting to 10‹ BÚ, adding asparagin and peptone, boiling, and again filtering. The wort so obtained is sterilized repeatedly at 115‹ to 120‹ 0., 1 to 1¢ per cent of agar is added and allowed to swell, and the mixture boiled, filtered, and again repeatedly sterilized. This subject-matter does not appear in the Specification as accepted.
