Abstract: 379,581. Regulating air supply to furnaces ; firebox doors. THORNTON, A. A., 7, Essex Street, Strand, London.- (Mineralochemie Akt.-Ges., fur Metallurgische und Chemische Produkte ; 23, Wiedener Hauptstrasse, Vienna.) Dec. 9, 1931, No. 34170. [Class 51 (i).] The over-fire air supply is automatically controlled inverselv as the suction in the furnace by means of a flap valve 3 fitted with a fixed and an adjustable counterweight. As shown applied to a locomotive firebox door, an opening 2 is controlled by a flap valve 3 fixed on a horizontal axle 4 having knife-edges 5 supported in bearings 14, 15. A counterweight 6 balances the weight of the flap and a counterweight 7 arranged on the shaft 4 is adjustable angularly and fixed by a set screw 21 so that the flap is applied with slight pressure against the inner edge 20 of the aperture 2. The bearing 14 is formed as a sleeve on a plate 16 fixed to the door by bolts 17, while the bearing 15 is formed on an angle piece 18 fixed to the door by bolts 19. A vertical grating 8 protects the door against radiant heat and preheats the entering air. The same firedoor can be used in furnaces of different sizes by hinging it in a separate frame which can be adapted to the size of the firebox opening. In a modification an outside flap is fixed to the flap 3 by an angle-iron so as to close the aperture when the draught increases excessively. Similar arrangements may be applied to openings in the firebox casing itself. The flap 3 serves, of course, to prevent emission of flame &c. in the event of an explosion &c.

Patent GB-361603-A (GB)
Title: Process for separating proteinases and carboxy-polypeptidases
IPC: C12N9/00
Filed: 1930-11-18
Abstract: Proteinases and carboxypolypeptidases occurring in the pancreas are separated from one another by subjecting mixtures thereof such as trypsin or pancreatin to a fractionating treatment with solvents, for example, acetone or alcohols such as ethyl or propyl alcohol, known to act as precipitants for enzymes.  The acetone or alcohol may be mixed with a solution of the enzymes until a concentration of about 50 per cent is attained, or solutions of the same concentration of these solvents may be used to extract solid mixtures of the enzymes. In each case solution becomes richer in proteinase, the carboxypolypeptidase remaining in the precipitate or residue.  By suitably altering the concentration of the proteinase solution, for example, by the addition of further acetone or alcohol, or by spray drying, the proteinase can be obtained in solid form.  The separation process may be repeated.  Examples are given, in one of which a solution of trypsin, the activity of which can no longer be increased by enterokinase, is treated.  The separation of the proteinases and carboxypolypeptidases of the pancreas by adsorbtion with specially prepared aluminium oxide is referred to.  The Specification as open to inspection under Sect. 91 (3)(a) comprises also the use as precipitating agents for treating the mixture of enzymes of suitable salts such as ammonium sulphate. This subject-matter does not appear in the Specification as accepted.

Title: A Device for Adjusting the Setting of the Headlamps of a Vehicle According to the Relative Position of the Headlamps of Oncoming Vehicles.
IPC: B60Q1/14
Filed: 1966-08-04
Abstract: 1,151,752. Controlling vehicle headlamps. PROJECTEURS CIBIE. 4 Aug., 1966 [3 Sept., 1965], No. 34966/66. Heading H4D. The Specification describes a system for automatically varying the vertical angle of a vehicle's headlamps in response to the detected elevation of an oncoming vehicle's headlamps. Thus whereby vehicle V, Fig. 1, would normally illuminate the road just in front of it and miss vehicle V 1 , in accordance with the invention, its hadlamp beam is raised through an angle α 1  in response to the high headlamps of vehicle V 1 . The headlamp P, Fig. 4, may be pivoted about K under the control of worm V and nut e. Photo-electric detection means carried by the headlamp comprises a lens O focusing the oncoming vehicle's headlamp on to an arrangement of three strip photo-cells A, B, C arranged vertically. The servo mechanism is such that the headlamps of the lowest oncoming vehicle is focused on narrow central photo-cell C. Thus each photo-cell output is fed to a differential amplifier D, E, F where its illumination is compared with that of ambient light photo-cell X. When the result of the comparison yields a high enough signal respective ones of trigger circuits G, H, I feed signals to logic circuit L. Circuit L causes the energization of appropriate ones of relays R 1 , R 2 , R 3  to energize worm motor M and cause the correcting tilting of the headlamp. When photo-cells A, B, C are inoperative, relay R 4  and contacts C 1 , C 2 , C 3  with nut-attached wiper b cause energization of the motor M to bring the headlamp to a predetermined position.
