IPC: C06F1/08
Abstract: 183,814. Voith, J. M. [Firm of]. July 29, 1921, [Convention date]. Fixed-bucket conveyers.-The containers 7 in automatic match machines are moved in endless series transversely to the ejection device 1 while the inserted bottom plates 13 are simultaneously lowered. Every bottom plate is guided by a parallelmotion device which on the leading-in side maintains it horizontal at the upper end of the container then graduallv inclines and lowers it until it becomes horizontal on reaching the lower part of the container when the container arrives at the discharging end. Every bottom plate 13 is carried by a plate 14 supported by links 15, 16 pivoted to a lever 17 having rollers resting on a rail 18, the inclination of which determines the elevation of the plates within the containers. The plates 14 are pivoted at the upper ends of rods 22 guided by rollers 23 mounted on the carriers for the containers. The lever 17 is also pivoted on the rod 22 so as to ensure the vertical position of the links 15, 16. To prevent the escape of matches when the bottom plates are inclined the points of attachment 24 of the links 15, 16 are below the plates 14 and the lower end of the plate 13 is thus pressed against the adjacent side of the container. On the other side is provided an inwardly projecting fillet 25 engaging a recess 26 in the plate. Surfaces 27, 28 guide the falling matches into the container. As the containers pass the ejection device they are filled with matches expelled from rods 19 by needles 20, their front sides being closed by a wall attached to a fixed part of the machine or by a flap. The filled containers with their bottom plates resting on flanges 11, 12 are removed to the delivery side (Fig. 1 left) and replaced by empty containers.

Title: Improvements in or relating to Automic Apparatus for Measuring Heights and Depths.
Inventor: INGENHOF JOHANNES
IPC: G01C13/00
Filed: 1916-12-30
Abstract: 109,556. Ingenhof, J. Dec. 30, 1916. Summing movements of varying extent; stop-mechanism.-A sounding-apparatus, adapted for measuring vertical distances in the atmosphere or the sea, employs a counting-apparatus actuated by the uniform descent of two weights one of which hangs slightly below the other. When the lower weight strikes the bottom, the slight lost movement produced is utilized to lock the counting-apparatus. Upon the drums 1, 2, Figs. 1 and 3, are wound steel wire ropes provided respectively with weights 21, 23 of which the weight 21 is the greater and hangs lower. The drum 1, the shaft 3 of which actuates a counting-mechanism, has mounted thereon a gear wheel 7 which engages a gear wheel 10 having spring connexion with the drum 2, the amount of lost motion between the drum and wheel being limited by stops 25, 25<1>, 26, Fig. 2. Pivoted to the wheel 10 are sleeves 11, Figs. 1 and 2, which receive pins 12 pivoted to the drum 2. These sleeves are recessed to receive a ring 14, which, when the sleeves 11 and pin 12 are inclined owing to the relative movement of the drum 2 and wheel 10, engages projections 15 on a pawl 17 that is pivoted to a lever 16 pivotally mounted on an enlarged portion 18 of the shaft 8. On the tilting of the pins 12 the pawl engages with the ratchet 19 attached to the wheel 10 and thus locks both drums. In operation the weights are lowered until the weight 21 is at the upper end of the depth to be measured and reading of the counting apparatus taken; the weights are then released and both drums rotate. Owing to the pull of the weight 21 the spring 20 is expanded until the stop 26 strikes the stop 25, whereupon the drum 2 and weight 10 rotate together. When the weight 21 touches bottom, the wire carrying it becomes slack and the drum 2 lags behind the wheel 10, rhus causing the pawl 17 to engage the ratchet 19 and lock the counter at a reading which exceeds the first reading by the depth.

Title: Improvements in or relating to oscillation mechanisms for irrigation lines
Inventor: HUGGAN JOHN AINSLEY
IPC: B05B3/04
Filed: 1960-05-27
Abstract: 962,313. Crop sprayers. JOHN HUGGAN & CO. Ltd. May 18, 1961 [May 27, 1960], No. 18780/60. Heading B2F. [Also in Division F1] An irrigation pipe line 39, 40 is attached to a tubular member 13 mounted for rotary oscillation in a bearing member 12 on a supporting post 11, and the tubular member has a crank 14 between which, and a stationary lug 21 on the post, is pivotally and removably mounted a piston and cylinder motor 15, 16 for imparting the said oscillations. The motor may be driven by a supply of water from the pipe line or from a separate supply, or by other liquid. In Fig. 1 a water supply for the motor is taken from the tubular member through the bearing member 12 at 61, and via a filter 213 and hose 41 to the inlet 24 of a sleeve valve 17. The valve is operated such that water is fed alternatively to the opposite ends of the cylinder, and exhaust water from the cylinder is delivered through an outlet 25 of the valve and a further, valve 32 and hose back to a discharge nozzle on the pipe line. The valve 17 comprises a casing integral with the cylinder within which a grooved sleeve is moved from one upper terminal position to a lower one; the casing has, besides the inlet 24 and outlet 25, further outlets leading via hose lines to the upper and lower ends of the cylinder and, depending on the position of the sleeve, water is fed to sand either ends. The sleeve valve operating mechanism includes a rod 30 with its upper end secured to a driving member 19 on the piston rod, so that the rod 30 is reciprocated with the motor piston ; it also passes through the sleeve and carries adjustable collar 33, 34 and helical springs 35, 36. Stops 51 on the collars are aligned with an axially slidable rod 53 normally held in the position shown by springs and having a notch 54 in which a roller 55 rests. The latter is attached to a spring-loaded plunger 52 which engages to one side or the other of a flange 50 on the sleeve to hold the sleeve in either one of its terminal positions. When a stop 51 strikes an end of the rod 53 the latter is moved so that the roller 55 leaves the notch 54 whereupon the plunger 52 is retracted to allow the appropriate spring 35 or 36 to move the sleeve to its alternative position; then as the piston moves in the opposite direction the rod 53 takes up its normal position and the sleeve is again held by the plunger. The amplitude of the oscillatory movement is varied by the adjustment of the collars 33, 34 on the rod 30, and the frequency by the valve 32 controlling flow from the outlet 25. The mounting of the motor and control assembly between the parts 14 and 21 may be completely reversed.

Filed: 1937-07-09
Abstract: In air or gas purifying apparatus, particularly <PICT:0480507/III/1> individual or collective filters for removing noxious constituents from respired gases, the exhaust of the filter materials is indicated by passing the gases, during or after passage through the filter materials, through electrically insulating material enclosed between two plates connected in a circuit including a signal, the insulating materials being capable of absorbing one or more of the gas constituents, thereby being rendered ineffective as insulators, whereupon the signal is operated.  The plates may be separated by the insulating materials alone or such materials may be coated on one or both plates enclosing conducting material or on the material itself. Where the filter is for carbon-disulphide, acetone, essence of turpentine, ether, carbon tetrachloride, chloropicrin, yperite, cellulose solvents and the like an insulating material soluble in the constituents may be employed, e.g. paraffin or benzoic acid, and such material may be coated or sublimed on to the plates or a mass of conducting material, such as active carbon, between them, or the conducting material may be dipped into the fused insulating material. The plates may be spring-pressed as described in Specification 450,825, [Group VI].  As shown a pair of plates 11, connected to one pole of a battery 17 in a circuit including an electric signal 16 enclose a plate 12 connected to the other pole, the spaces between the plates being filled with indicator insulating materials 13, 14, for different classes of noxious constituents.  The signal current may be used to operate a relay circuit including a signal or an auxiliary motor employed to replace the exhausted filter by a fresh one.
