Abstract: 978,009. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 29, 1962 [Nov. 29, 1961], No. 40717/62. Heading B6B. A sheet conveyer comprises a chamber including a concave curved wall, a sheet exit slit in said wall communicating with an exit channel extending substantially tangentially to said wall, means for admitting sheets into said chamber, means for directing a gaseous fluid under pressure to flow over said wall so as to tend to maintain said sheets in close proximity with said wall and to convey said sheets along said wall and out through said exit slit. A loose assemblage of sheets 16 is contained in a hopper 15 closed by a door 52 pivoted at 53 and urged towards the closed position by a spring 54. The door is opened by means of a solenoid 55. The hopper opens into a chamber 10 comprising a flange member 12 closed by a transparent cover 13. Blades 44, carried by U-shaped wire frames 45, are mounted on a sleeve 42 secured to a shaft 40. The latter is rotated by belts 46, 50 and pulleys 47, 49 and 51. Pulleys 47, 49 are connected through a slip clutch 48. Air is blown into the chamber through inlets 20 positioned at a tangent to the peripheral wall 11 of the chamber to create a low-pressure high-velocity zone adjacent the wall, which together with the action of the blades conveys the sheets around the chamber and out of an exit 21. The sheets are fed along a guide 22 by a pair of spaced belts 25 passing around pulleys 27 at their lower ends. Said pulleys are mounted on a pivoted support 30 spring-biased against a stop 32. Double feed is prevented by rollers 34, 35 rotating in the same direction, the roller 34 rotating at a higher angular velocity and having a greater coefficient of friction with the sheets than the roller 35. The sheets are registered against a side wall 37 by a skewed roller 36 and fed by rollers 38. The belt 50 also drives a D.C. generator 57 coupled to the solenoid 55, so that as long as the blades rotate faster than a predetermined value, the door 52 will be held open to admit sheets into the chamber.

A single electromagnetic-valve 16a and compressor motor 14a for the pneumatic springs of the front axle (not shown) are controlled by a single contact 20a through a circuit including a similar relay 37a and loop 40a. The valves 16, 16<SP>1</SP> (Fig. 1) control passages connected to a central chamber 11 containing the compressor 13 with chambers 12, 12<SP>1</SP> connected by tubes 8, 8<SP>1</SP> to the cylinders 3, 3<SP>1</SP>. When the chassis is low the contacts 20, 20<SP>1</SP> engage contacts 21, 21<SP>1</SP> and an impulse from the accelerator contact 26 is transmitted to the windings of the valves 16, 16<SP>1</SP> which open to supply air from the chamber 11 to the cylinder 3, 3<SP>1</SP>. Current is simultaneously supplied to a winding 36 to close the relay 37, whereupon the contact 26 is by-passed and current flows to the valves 16, 16<SP>1</SP> through conductors 34, 38 until the contacts 20, 21 and 20<SP>1</SP>, 21<SP>1</SP> separate. When the chassis is high contacts 20, 22 close and an impulse from the contact 26 energizes a coil 32 to close a relay 33 feeding the compressor motor 14 and air is withdrawn from the cylinder 3, 3<SP>1</SP> for storage under pressure in the chamber 11. The relay 33 also supplies current through the loop 40 to the contacts 20, 22 and the winding 32 so that the motor 14 is supplied until the contacts 20, 22 open. The front axle control circuit functions in similar manner.

Title: Improvements in and relating to breech mechanisms of automatic fire arms
IPC: F41A9/27
Filed: 1958-12-22
Abstract: 905,130. Automatic firearm reloading gear. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLI. KON. Dec. 22, 1958 [Jan. 9, 1958], No. 41373/58. Class 92. Reloading mechanism for a firearm is actuated by a driving piston 14 sliding in a cylinder 15 in response to gas pressure in a chamber 24 from a driving cartridge 20 held in a rotatable sleeve 17 which is connected by stepped-action gearing to the piston 14, so that when a spring 9 returns the piston to its position of rest, the sleeve is turned to bring another driving cartridge into its firing position in communication with the chamber 24.. For normal firing gas from the barrel 3 is bled to two cylinders 7 causing two pistons 6 to push back a 4 slider against a reloading spring 9 and, by way of studs on the chamber block 2 co-operating with grooves on the slider, to rotate an unfired cartridge into the firing position. On return of the slider 4 by the spring 9 a lug 12 loads a bulletted cartridge 11 into the chamber block (Fig. 1). If special reloading is required a firing pin 22 is caused to fire electrically a driving cartridge to force back the two-part piston 14 against a spring 16 so that its rear portion 14b actuates the slider 4 to load a cartridge 11 as before. The ends of a pin 38 fixed transversely on the piston 14 engage in slots 15c in a control sleeve 25 causing it to rotate as the piston travels backwards and forwards. The sleeve 25 carries on its front end double-ended pawls 26 and 27 on pivots 28 and 29 whilst, in the same plane, a double-ended pawl 34 on a pivot 35 and a spring catch 34 are carried on the end of the cylinder 15. These pawls and the catch co-operate with a cam 15e, as the sleeve 25 rotates relative to the cylinder, to engage and disengage successively in a manner indicated in Figs. 4 and 5 with internal splines in the rear end of the sleeve 17 in which are the cartridges 20. Release of a catch 23 allows removal of the cylinder cover 21 so that the sleeve 17 can be reloaded. The front end of the chambers in the sleeve 17 are obturated by sealing bushes 19 which have thin rear ends that can expand against the chamber walls and flat front ends to bed against the cover 21. Bores 21a connect the chambers with the channels 15a leading to the chamber 24. For initial loading of a belt of the cartridges 11 into the firing mechanism the slider 4 can be operated by hand by way of the piston stem 14c.

Abstract: 1466126 Flash-lamp unit PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 Sept 1974 [28 Sept 1973] 41696/74 Heading G2X A flash-lamp unit comprises a plurality of percussion-ignitable flash-lamps arranged in at least one row and mounted on an elongate base-plate, a corresponding plurality of striker springs each locked in an energized condition and which are each designed to strike a portion of a respective one of the flash-lamps on being unlocked, to ignite that flash-lamp. At least one elongate body e.g. 21, Fig. 2, is movable in steps in the longitudinal direction of the base plate and has a number of projections (22 to 26) of step like shape each designed to unlock a respective striker spring (6 to 11) from the detents 18, which may be part of the base-plate or may be a bent part of the striker spring, and to effect step-wise longitudinal movement of the body. In firing the body is movable in such a direction that the projections move in a direction substantially transversely to the plane of the base-plate. A transport spring 32 acts on the beam 21 in the longitudinal direction. Stabbing action on pin-shaped member P in the direction of the arrow causes the beam 21 to be lifted, tread 37 lifts the spring 6 over detent 18 and the flash-lamp is fired. Beam 21 is then moved by spring 32 until riser 38 of second tread 39 touches the striker spring 7 and projection 23 is in the initial position to unlock spring 7 for  firing the next flash-bulb. Other modifications are described in which different forms of pivoted, or in one case a laterally movable, bodies having projections for sequentially releasing the striking springs are used.

Abstract: 1,128,371. Diagnostic composition for hydrolytic enzymes. MILES LABORATORIES Inc. 4 Oct., 1965, No. 42053/65. Heading B1X. A diagnostic composition for detecting hydrolytic enzymes in body fluids comprises a bibulous carrier impregnated with an indoxyl or thioindoxyl ester. In the presence of a hydrolytic enzyme the ester is hydrolysed and a blue or red pigment of the indigo or indirubin type is formed by oxidation with the ambient air or an oxidising agent incorporated in the composition. The acid radical of the ester is selected having regard to the enzyme to be detected: acetate, butyrate, laurate or stearate for an esterase or lipase according to the length of the alkyl chain, phosphate (for phosphatases), sulphate (for sulphatases), glucuronide (for glucuronidases) or glycoside (for glycosidages). A suitable buffer may also be incorporated. By adding to the body fluid to be tested an inhibitor for one or more enzyme (e.g. eserine for pseudocholinesterase or NaF for pseudocholinesterase and aryl esterase), the relative proportions of various enzymes may be determined. Specified substituted indoxyls are the 5-bromo, 5-bromo-6-chloro, and 5-bromo-4 chloro-derivatives. Comparative details are given of alphanaphthyl acetate-Fast Blue B papers.
