Abstract: 470,521. Arc-rupturing in switches. LEYHAUSEN, W. May 4, 1936, No. 12542. Convention date, May 3, 1935. [Class 38 (v)] A spark-chamber for automatic cut-outs with magnetic spark-extinguishing of the kind provided with an outlet opening for the arcing on switching off, is provided towards the centre of the blow-out field with a fresh air supply bore terminating between the contacts and through which the air is drawn by the vacuum resulting from the blowing of the arc and is drawn further through the chamber in the direction of the arc movement. The arcs o, o<1> formed in the chamber f when the movable bridging contact c is separated from the fixed contacts a, b, are acted on by the blow-out fields of magnets m, m<1>, Fig. 2, so that a partial vacuum is produced in the contact-space. Fresh air is thereby drawn into the chamber f through the bore i, space k in the base, channels r, t in the underside of chamber f, and through the openings in the chamber around the contacts a, b, and is then driven outwards with the arcs. Partition walls w, w<1> provide channels n... n<3> and orifices for cooling the gases which can then discharge into the switch case without doing damage. The Specification as open to inspection under Sect. 91, states that a further improvement could be obtained by inserting additional walls longitudinally in the chamber, in which case the channels n &c., might be omitted. Figures of performance were given for two different blow-out magnets, one with and the other without, the longitudinally-arranged walls. This subject-matter does not appear in the Specification as accepted.

Filed: 1917-09-04
Abstract: 118,669. Nieuwenhuyse, E. Sept. 4, 1917. Parapet mounts.-Relates to guns of the kind which can be raised and lowered with respect to a pit or parapet, and which have an upper shield that completely covers the gun and mounting when the gun is in the normal or lowered poeition, the shield being moved rearwards to clear the muzzle end of the gun when this occupies a firing position above the pit or parapet. The invention consists in the combination of a special pneumatic raising and lowering gear with special means for supporting and operating the shield. Fig. 2 shows the gun A and shield 2 in the firing position, and Fig. 3 shows the gun lowered below the parapet X and covered by the shield. The gun is mounted in a cradle D pivotally supported at the rear on links E and carried by trunnions G on blocks H adapted to slide vertically in guides in the carriage F. These blocks are connected to the hollow piston-rod I of an air-pressure piston- and-cylinder device N, J having a valve M controlling an aperture in the piston N and acted upon by a spring-controlled lever 0 retained in the firing position by a pawl S engaging a notch Q. To fire the gun, the pawl S is released by pulling a lanyard T, the lever 0 being rocked by its spring Y in the anti-clockwise direction to operate the firing-mechanism of the gun and to open the valve M against the action of a spring L. The gun is then able to fall by its own weight, the air below the piston being exhausted through ports Z, I. To raise the gun, the bell-crank lever U, V is operated to raise the lever 0 from the valve spindle K and permit the spring L to close the valve M, so that the air pressure may act beneath the piston. Fig. 3 shows the shield 2 supported by arms 3 and adapted to slide in dovetail guides 4 on the mounting when the arms 3 are swung rearwards by operating a screw gear 6, 7, 8. The gun may be raised and lowered by a hand-operated supplementary screw gear 12, 11, 10.

Title: The separation of aminoacids from acid hydrolysates of proteins
Filed: 1939-04-04
Abstract: 527,485. Amino-acids. TOENNIES, G. April 4, 1939, No. 13062/40. Convention date, May 7, 1938. Divided out of 527,320. [Class 2 (iii)] Amino-acids are separated from mixtures containing inorganic salts such as are obtained by the acid hydrolysis of proteins, by adding a strong acid such as hydrochloric or perchloric acid, and dissolving the resulting amino-acid salts in a solvent in which the inorganic salts are insoluble. The solution of amino-acid salts is then treated with an organic base such as amylamine to precipitate the free amino-acids. Suitable solvents are alcohols (methyl to amyl) acetone, acetic acid, ether, and chloroform, and also mixtures of solvents ; 'and other suitable bases are pyridine, aniline, dimethylaniline and butylamine. With perchloric acid a greater range of solvents may be used than with hydrochloric acid. In examples (1) a hydrochloric acid hydrolyzate of egg albumen is neutralized with caustic soda and evaporated ; hydrochloric acid equivalent to the free amino groups of the amino-acids is added together with isopropyl alcohol, the sodium chloride being filtered off ; amylamine is then added to precipitate the free amino acids ; (2) the same initial mixture is treated with perchloric acid in glacial acetic acid and ether is added, amylamine being added to the filtrate from the sodium chloride as before.

Title: Improvements in or relating to fuel-injection engines
IPC: F02M69/44
Filed: 1960-04-13
Abstract: 923,695. Regulating. ANDRE CITROEN S.A. April 13, 1960 [June 23, 1959], No. 13153/60. Class 7(6) In a fuel injection engine, of the kind defined in Specification 622,197, the time lag between a sudden depression of an accelerator pedal and the increase of fuel output is suppressed by an auxiliary vacuum, created by a bellows connected directly or indirectly to the pedal, which acts upon a vacuum-responsive member controlling the fuel output. On depression of a pedal 1, Fig. 1, a movable wall 2a creates a vacuum in a pipe line 3 connected to a conduit 4 which connects vacuum-responsive fuel control member 17 with air inlet Venturi 15 through an orifice 5. A momentary over-pressure in the conduit 3 caused by release of the pedal, is prevented from communicating with the conduit 4 by a non-return valve 7 and is vented by a non- return valve 8, and excessive vacuum caused by sudden pedal movement is relieved by a non- return valve 6. In a modification Fig. 2, the wall 2a is connected to a diaphragm of a chamber 10 which is responsive to the vacuum prevailing downstream of the air intake throttle control. Thus a vacuum drop, caused by a sudden opening of the air throttle, allows a spring 11 to move the diaphragm and thereby the wall 2a.

Title: Improvements in and relating to optical microscopes
IPC: G02B21/24
Filed: 1956-04-30
Abstract: 819,899. Optical microscopes. BAKER OF HOLBORN Ltd., C., and CURTIES, M. G. L. April 30, 1957 [April 30, 1956], No. 13190/56. Class 97(1) For effecting several independent adjustments, an optical microscope has a plurality of actuating means each including a manually operable control member, a plurality of such members being arranged in a group or cluster on a panel As shown, the lens tube 14 is attached to a slide member 15 slidably mounted on vertical support 11; a connecting rod 17 rigidly attached to the slide member 15 has its lower end resting on the end 18 of a horizontal lever 19. The other end 22 of the lever 19 carries a cam follower engaging a helical groove 23 in the surface of a driving member 24 located under the front face of the panel 13. Rotation of the knob 28 causes rotation of the driving member 24 and hence vertical motion of the lens tube by means of the cam follower and lever action to provide coarse focusing adjustment. For fine focusing adjustment, a knob 31 is mounted co-axially with the knob 28 and separated therefrom by a ball race 32. The knob 31 carries a shaft 33 engaging on a cylindrical member 34 which projects into a cavity in the driving member 24 and is carried by a fixed base member 35. A spring 36 extends between the cylindrical member 34 and an internal flange 37 on the driving member 24. On rotation of the knob 31, the shaft 33 rotates due to its threaded engagement with the cylindrical member 34 and the spring 36 urges the driving member 24 upwardly with accompanying pivoting of the lever 19 to effect fine focusing adjustment. Similarly, vertical movement of the condenser assembly 37 is effected by a knob 43 operating a lever 39. Horizontal motion of the stage 16 in two independent perpendicular directions is effected by co-axial knobs 64, 56 controlling coaxial cam grooves 51, 61 which-by means of cam followers-cause the motion to the levers 45, 57, the ends 58, 44 of which abut on adjacent edges the stage to move it in the direction of the arrows. All the movable components are ball mounted in a manner described in Specification 819,900. A further knob (not shown) controls a rheostat for variation of intensity of the specimen lighting means. A second embodiment of the invention provides only the coarse and fine focussing adjustment.
