Title: Improvements in or relating to machine guns
IPC: F41A19/31
Filed: 1932-05-30
Abstract: 491,337. Machine guns. KRAUS, O., and MOESSMER, E. May 30, 1932, No. 15305. [Class 92 (ii)] Relates to machine guns operated by a crank driven by external means, a lost-motion device being interposed between the crank and the breech-bolt whereby the breech-bolt is retracted only after the crank has made a predetermined angular movement from its front dead-centre position corresponding to the closed and locked position of the breech-bolt. According to the invention, means are provided for positively nullifying the effect of the lostmotion device during the first portion of the return movement of the crank. As shown, the breech-bolt 1 has a pin 12 in a slot 11 in a link 10 pivoted at 9 on the crank 8, and a lever 15 is pivoted at 1.6 on the link 10 and is controlled by a cam 17 on the crank. In the position shown in Fig. 1, the gun has just been fired. Clockwise rotation of the crank 8 first takes up the lostmotion provided by the slot 11. During this time, a earn 4 driven with the crank 8 releases a catch 3 which is withdrawn by a spring 5 to unlock the breech-bolt. Further rotation of the crank retracts the breech-bolt. During this period, the spent cartridge is ejected, a fresh cartridge is fed, and the firing-pin 6 is cocked by a lug 20 on the lever 15 engaging a pin 19 on the firing-pin. The firing-pin is held cocked by a sear 21. Near the end of this period, the cam 17 rocks the lever 15, the left end of which then locks the pin 12 in the left end of the slot 11. During the return of the crank, the breech-bolt is positively brought to the closed position when the step of the cam 17 releases the lever 15 which in turn releases the pin 12. While the crank completes its return movement, the cam 4 depresses the catch 3 which locks the,breech-bolt and rocks the sear 21 to release the firing-pin. In a modification, Fig. 8, the breech-bolt 1 is locked by two interconnected catches 3a, 3b moved to the locking position by the cam 4 and to the unlocking position by cams 33 on the link 10. The cam 4 is on a shaft 35 connected by bevel gearing 36 to the crank 8, and these parts are driven by a chain-wheel 37 through a slip coupling 38 to prevent damage if the mechanism jams. The mechanism may be driven from a shaft 24, Fig. 7, carrying a disc 25 with a tooth 26 adapted to engage a tooth 28 on a free chain-wheel 27 to drive this chain-wheel to transmit motion to the breech-mechanism. To stop the drive, the chain-wheel 27 is pulled away from the tooth 26 by means of a Bowden wire, whereupon a'tooth 29 on the other side of the chain-wheel rides past a spring 32 and is stopped by a tooth 30 on a fixed member 31. The teeth 29, 30 are so positioned that the breech-mechanism stops in the open position.

Patent GB-889110-A (GB)
Title: Improvements in or relating to devices for obtaining a residue by evaporating water
IPC: C02F1/04
Filed: 1958-05-14
Abstract: <PICT:0889110/III/1> A device for obtaining a residue from a predetermined quantity of water comprises a vessel of known volumetric capacity, which is filled with the water to be evaporated, and also comprises an evaporation bowl which is smaller than the vessel and which is housed in a glass container and is movable vertically so that the vertical motion controls: (a) fluid pressure means which supply water from the vessel to the bowl when the quantity of water therein falls to a given minimum value and interrupts this supply when the quantity is restored to a given maximum value; and (b) the electrical circuit of heat sources outside the glass container so that the supply of heat is interrupted while the vessel is being filled.  A 50 c.c. platinum bowl 16 is mounted on vertical shaft 14 which is recessed at 17 and carried a plate 20 which rests on roller 23 balanced by counter-weights 24.  When there is only little water in the bowl the counter-weights raise the bowl so that the recessed portion 17 of the shaft forms a connection between pipes 9 and 11 through which compressed air passes to a vessel containing a measured quantity of water some of which is thereby forced into the bowl through pipe 31 till sufficient water is supplied to the bowl to depress the shaft and break the connection between pipes 9 and 11, surplus air pressure in the supply vessel being dissipated through regulated leak 12.  The device is housed in a glass container 4 and that portion of pipe 31 within the container is housed within pipe 33, compressed air passing from line 9 to within the container between pipes 31 and 33.  More compressed air is introduced into the container through aperture 29 in a pipe 28, the compressed air and water vapour escaping through outlets 5 in the container 4.  The plate 20 in the lower position of the bowl touches electrical contact or switch 26 which operates external electrical heat sources, e.g. heat radiating incandescent lamps which evaporate the water in the bowl and are switched off when plate 20 rises and meets contact 25.  The device may be used to obtain a residue of organic impurities from water which has been freed from inorganic impurities.

Filed: 1975-04-15
Abstract: 1509085 Spreading implements C VAN DER LELY NV 15 April 1975 [25 April 1974] 15521/75 Heading AID  Powdered fertilizer (or liquids) is passed from a container 2 to delivery ducts in which a conveying air stream is maintained, the ducts being provided at their ends with driven spreaders which may take a variety of forms. Fertilizer flows through adjustable ports 4 onto a vaned rotating disc 5 and is assisted into the ducts 18-25 by the air-flow from a fan 16. Pivots at 43 and 46 permit the delivery ducts 18, 19, 20 and 23, 24, 25 to be swung to the rear for transport. The spreaders may be equally or unequally spaced across the implement. In Fig. 3, each spreader is a nozzle 30 connected by a flexible tube 31 to the end 32 of the delivery duct e.g. 20, and the nozzle 30 is oscillated transversely of the implement by a link rod 35 connected to a reciprocating rod 36 (Fig. 3), or 36, 49, 47 or 48 (Fig. 2), to produce a zig-zag spread (Fig. 4, not shown). The rods 36, 49, 47, 48 are connected (via gear boxes 37, 40) eccentrically to a wheel 39 on main shaft 9. In Figs. 5, 6, 7 (not shown), each spreader is an oscillating nozzle (75) which is flattened and arranged so that its axis is inclined forwardly and downwardly and its greatest width is vertical. The nozzle (75) is pivoted to the duct 70 and axis of oscillation is at 45 to the vertical. The link rod (78) is rigid with the nozzle (75) and pivoted to the reciprocating rod 36. In Fig. 8 (not shown), each spreader (91) is a convex plate spaced from the end of the delivery duct (87) and oscillated by the reciprocating rod (93) via a pivoted link (90). In Fig. 9 (not shown) each spreader (115) is a bladed circular plate (119) spaced from the end of the delivery duct (87) and fastened to an upright shaft (116) which is journalled in the end of the delivery duct (118) and which is driven.

Abstract: 369,078. Bottle-capping machines. JONSSON, A. J., Link÷ping, Sweden. May 27, 1931, No. 15552. [Class 125 (iii).] In a bottle-capping machine of the type provided with a tool for inserting a packing disc of cork &c. into the cap, said tool having two parts, one for holding the cap and the other for inserting the disc, if the insertion member meets an abnormal resistance, such as a misplaced cap or disc, a resilient connection contained in the drive device of the insertion member effects a stoppage of the machine. In one application, the insertion member 21, worked from a cam disc 38 by a two-armed lever 26, push rods 30, 31, and the resilient connection 40, inserts a cork disc 24 into the cap 23 held by the part 4, below which the cork discs are fed one at a time, by a device 10, 14, 15, 16 worked from the cam shaft 2. If the insertion member 21 meets an abnormal resistance the action of a cam-ended lever 46 carried by the sleeve 41 and the cam ring 49, displaces the lever 46 laterally and through a push rod 50 moves a link 53 into the path of a bunter 54 to stop the machine. The pin 50 may slide in an arm carried by the sleeve 41 and engage the cam 49. If the member 4 contains no cap the resistance is provided by a stopping member 64, which is normally pushed back against the action of the spring 65 by the cork disc 24. A shoot 72 for the escape of cork particles is provided in the insertion member.

Title: A device for measuring electrical current
IPC: G01R15/24
Filed: 1966-04-12
Abstract: 1,094,286. Measurement of current in high voltage line. ETABLISSEMENTS MERLIN & GERIN S. A. April 12, 1966 [April 10, 1965; March 3, 1966], No. 15813/66. Headings G1A and G1U. The current in a high voltage line is measured by passing polarized light through a first Faraday effect device 17 having a coil 16 excited by the line current such that the plane of polarization of the light-beam is rotated in proportion to the current, a second Faraday effect device 18 being located at earth potential and disposed so that the light-beam passes through it, the current in the coil 19 of the second device causing compensating rotation of the polarization plane and being proportional of the current in the line. Light from a source 11 (visible, infrared or ultraviolet) located at earth potential passes through an optical system 12 and prisms 14 to a polarizer 15. The plane of polarization is rotated according to the current in the coil 17 connected in the high voltage line by passage through the body 16 of high Verdet constant. Compensating rotation is carried out by the similar body 18 located at earth potential the current through the coil 19 of which is proportional to the line current. In order to compensate for intensity fluctuations caused by ageing of the source, detector &c., a beam splitter 22 is used to direct divided beams to two photomultipliers 21, 23 which are connected in opposition and feed an amplifier 25 whose output is used to supply the compensating coil 19 and a load 26. The beam splitting plate 22 is set at Brewster's angle to the incident beam, thereby obviating the need for analyzers for the detectors. However, in order to increase the sensitivity of the apparatus, respective analyzers 26, 28 may be provided for the detectors, the polarization planes of which are set at the optimum angle with respect to the polarizer 15, to provide high sensitivity. The load 26 in the compensation circuit may be a measuring device or relay &c. There is arranged to be some difference in the number of turns of coils 17 and 19 to provide a detector output by which the amplifier 25 can operate.
