Title: Process and machine for automatic filling of definite quantities by weight of a powdery or granular material into pasteboard boxes, paper bags or similar receptacles
IPC: B65B1/28
Filed: 1936-02-13
Abstract: 452,563. Filling-machines. BERTELSEN,H. J. V., JENSEN, J., and HANSEN, A. L., (trading as INTERESSENTSKABET FACTIO), 53, Rentemestervej, Copenhagen. Feb. 13, 1936, No. 4363. [Class 94 (i)] In filling-machines of the kind in which the containers are filled by filling tubes extending to the bottom thereof, and are arranged to travel on a sloping rail to lower them from the funnels, the intermediate part of the rail is smooth and arranged to vibrate, and the upper and lower parts are stationary members. As shown, a disc 3, rotatable on a vertical shaft 1, carries a number of filling funnels 4 to which filling tubes 5 are attached. The rear or inner half of each filling tube is enclosed by a channel - shaped guide 6, to afford lateral support to the receptacle to be filled. The receptacle is supported with its base pressed against the lower end of the filling tube, by a rail 7, the spiral shape of which allows a gradual lowering until the filled receptacle is free of the filling funnel. The middle part of the rail 7 is vibrated by a rod 9, and the funnel is tapped by a hammer 17. Predetermined quantities of powder &c. are fed into the funnels, when the receptacle is in its uppermost position, through a stationary hopper 13, Fig. 3, and when the disc 3 rotates in the direction of the arrow B, a scraper 15 removes any material from the flanges of the funnels 4. Springs 16 assist in the positioning of the receptacle on the tube 5. To prevent the formation of dust, a stationary suction channel 10 is arranged over the disc 3.

Title: Improvements in photographic flash apparatus
IPC: H05B41/32
Filed: 1959-02-09
Abstract: 912,807. Charging and discharging condensers for photo-flash apparatus. MULTIBLITZGERATE Dr. ING. D.A. MANNESMANN GES. FUR. Feb. 9, 1959 [Feb. 7, 1958], No. 4383/59. Class 38 (4). Photo-flash equipment is provided with a selector switch 10, 22 so that a flash tube 4 can be arranged to emit a series of normally powered flashes whilst focusing and other operations are carried out or to emit a single powerful flash when the exposure is made. When it is required to focus the camera the switch 10 is moved to the lower contact and the switch 22 opened. A small condenser 12 then charges from a transformer 1, connected to an A.C. supply, over a rectifier 5 and a resistor 11. A condenser 16 is also charged from the rectifier 5 by way of a voltage divider 13, a resistor 15 and the primary winding of a transformer 17, the voltage at the condenser 16 being the anode voltage of an ignition thyratron 19. Since switches 22, 26 are open the control grid of the thyratron 19 is supplied with unsmoothed D.C. from a rectifier 20 by way of a voltage divider 21. The thyratron 19 thus ignites at a frequency of 100 times a second, the condenser 16 being discharged each time the thyratron 19 ignites thus applying an igniting pulse to the starter 18 of the flash tube 4 by way of the transformer 17. The tube 4 thus ignites due to the discharge of the condenser 12 therethrough. Due to the persistence of vision the tube 4 appears to be continuously lit, allowing focusing and other operations to be made. When it is required to make an exposure the switch 10 is moved to its upper position and the switch 22 closed. The output of the rectifier is now smoothed by a condenser 23 such that the thyratron is cut off. The camera contact 26 is closed at the instant of exposure whereupon a condenser 24 is placed in parallel with the condenser 23. This momentarily reduces the bias on the grid of the thyratron 19 whereupon the condenser 16 discharges to give an igniting pulse to the starter 18 and the large condenser 9 discharges through the tube 4, giving an intense flash. A condenser 6 is provided to compensate for load fluctuations. Specifications 912,808 and 912,809 are referred to.

Title: Improvements in or relating to gas burners suitable for simmering and other cooking operations
Inventor: BRADLEY JAMES ALBERT
IPC: F23D14/06
Filed: 1961-02-06
Abstract: 936,752. Gas burners. GAS COUNCIL. Feb. 6, 1962 [Feb. 6, 1961], No. 4415/61. Classes 75 (1) and 75 (3). A gas burner comprises a burner head having two separate passages communicating with burner openings 36, 40 disposed around a burner head and valve means 13, 14 for controlling the supply of aerated gas to one passage and of non-aerated gas for low rate consumption to the other passage. The burner head comprises three main parts 28, 29, 30. Either the port 29, Fig. 1, or the port 28, Figs. 5 to 7, not shown, has projections 38 so that aerated gas supplied through a mixing pipe 22 can pass between the projections 38 into a main burner opening 40. Gas entering the supply pipe 17 enters an annular space 35, and passes between the projections 33 of the part 29 providing a simmer flame at the circumferential groove 36. The main gas supply is permanently connected through a recess 50 with large and small inlet ports 51, 52. The small inlet port 52 is connected through an arcuate groove 47 with a port 18 leading to the non-aerated gas supply pipe 17. The large inlet port 51 is simultaneously connected through a short arcuate groove 46 and plug passages 45, 44 with an injector 16 opening into the mixing pipe 22. If the valve plug is turned anticlockwise the supply to the port 18 is eventually cut-off and the supply to the injector increased. Clockwise rotation of the plug cuts off the supply to the injector and eventually that to the pipe 17 also. A flash - back tube 53 has one end adjacent to the space 40 and the other to a continuously burning micro-jet, such that gas entering the tube is ignited by the micro-jet and consequently ignites the burner. In a modification aerated gas issues from a passage in the burner part 29 into the adjacent flash-back tube. In another arrangement a cross-lighting jet supplied from the pipe 17 is situated between the groove 36 and the end of the flash-back tube remote from the micro-jet 54. The micro-jet may be replaced by an electrical igniter rendered operative by the turning on of the gas valve 13, 14.

Abstract: 757,044. Clocks. JUNGHANS H. and JUNGHANS AKT.-GES., GEB. Feb. 16, 1954 [Feb. 16. 1953]. No. 4580/54. Addition. to 698,810. Class 139. An alarm clock comprises means for automatically changing the ringing volume during the running down of the alarm spring. The alarm mehanism is similar to that described in the parent Specification and comprises a control disc 1 which is frictionally mounted on the alarm spring arbor 9 and which determines the amplitude of swing of the hammer 3, Figs. 1 and 3. A locking lever 5 is'so located that its arm 5a arrests the disc 1 in the position shown in Fig. 3, in which it limits the amplitude of swing of the hammer 3 until the alarm spring 8 expands sufficiently to meet the arm 5b of the lever 5 which is thereby rocked to free the disc 1 which then rotates until arrested by the stop 10 and the alarm hammer 3 is allowed its full swing and strikes the gong (not shown). After further expansion of the alarm spring 8 the lever 5 is moved sufficientlv for its arm 5c to arrest the alarm mechanism. Fig. 1. The locking lever may be generally V-shaped and mounted between two mechanism plates, Fig. 4 (not shown). In a second example the control disc 31, Fig. 5, is not moved immediately the alarm mechanism is released but only when a finger 33 frictionally mounted on the alarm spring arbor 9 has rotated substantially a complete revolution to meet a projection 13e of a spring,32 frictionally connected to the control disc. The spring 32 may be omitted and the hub of the control disc shaped accordingly. In the third example the control disc 41, Fig. 15, is frictionally mounted on the alarm spring arbor and has projections 42, 43, 44, which co-operate successively with a spring detent 45. A finer 46 is mounted on the alarm spring arbour 9. The arrangement is such that each projection 42, 43, 44 is arrested in turn by the detent while the alarm spring arbor 9 continues to rotate until the finger 46 deflects 'the spring detent 45. Fig. 18, sufficiently to free the projection 42, 43, 44. The duration of the "soft" alarm period is thereby increased.

The pyrophonic lighter of the parent Specification having a liquefied gas container with a filling valve provided with a hollow needle for connection to a filling vessel and with a movable valve member 3 arranged to compress a flexible resilient closure member 23 for closing a fuel filling passage 20 and an escape passage 21 for air and gas from the container has a rigid member 15 interposed between the movable member 3 and the closure member 23 and a stop 19 which limits the withdrawing movement of the rigid member 15 in the filling position and prevents withdrawal of said rigid member and closure member when the movable member 3 is separated from its co-operating fixed valve part. As shown, the member 3 which is screwably moved in a fixed centrally recessed part 2, secured to the bottom 1 of a lighter fuel container, by co-operation with the neck 27 of a filling can inserted into a recess in the member has at its inner end a bore 24 which accommodates the collar 16 of the rigid plate 15 which contacts the rubber closure member 23 and is limited in its upward movement by the ring 19 force fitted or screwed into the closed end portion of the central recess in the part 2. In its uncompressed condition the closure member 23 leaves a space between it and the walls of the part 2, and bears on a rib 10 in the bottom of the central recess so as to prevent communication between two grooves 11, 12 one on-each side thereof said grooves communicating with the interior of the container respectively through the passages 21 and 20 in the bottom of the central recess. The groove 12 also communicates through a blind bore 13 in the bottom of the central recess with the hollow needle 14 secured in the collar 16. The groove 11 also communicates with the atmosphere through the space surrounding the closure member 23, a groove 25 in the ring 19 and clearance provided between the walls of the bore 24 and the collar 16. When the member 3 is screwed home into the part 2 the plate 15 compresses the closure member 23 to seal the grooves 11, 12 and to form a seal between it and the walls of the central recess to cut off communication between the passage 11 and the atmosphere. The end of the central recess may be formed as a plug 6 screwed into a bore in the end of said recess. In a modification the needle 14 may be secured in the movable member 3 and pass freely through a central hole in the plate 15 which is then without the collar 16.
