Abstract: 615,078. Lawn-mowers. STEVENS, A. H. (Atwood Vacuum Machine Co.). Aug. 23, 1946, No. 25193. [Class 6 (ii)] The ledger blade 28 of a lawn-mower is mounted on a pair of levers 50, one on each end of the blade, the levers being pivoted on the side plates of the machine, which are provided with screw devices for adjusting the blade relatively to the cutter reel 24, spring means being associated with one of the levers to maintain the operative relation between the ledger blade and reel. In the form shown, the mower frame comprises a pair of side plates 18 joined by cross-members 20, 21, the cutter reel being rotatably mounted between the side plates. The ledger blade 28 is of arcuate form and is carried by levers 50 pivoted on studs 32 on the side plates. The blade is resiliently urged towards the reel 24 by the action of springs 47 attached to the levers and is adjustable by the rotation of milled heads 61 carried by adjusting screws which bear against the upper ends of the levers 50. The height-adjusting roller 27 is mounted on an axle 29 carried by plates 31 also pivoted on the studs 32. Each plate is provided with notches 40 selectively engaged by the end 39 of a pivoted latch 37 which is urged into engagement with a notch by the spring 47. In a modification, the ledger blade, which is doubleedged so that it may be laterally inverted when worn, is provided with serrated cutting edges.

Title: Improved process for the manufacture of a mixed manure containing a variable amount of nitrogen and phosphates
IPC: C05C9/00
Filed: 1920-09-02
Abstract: The process of the parent Specification is modified by the use of acid salts for effecting the conversion of the cyanamide into urea. The acid salt may contain an element, such as potassium, of manurial value.  For example, sodium or potassium bisulphate may be used, the solution concentrated in vacuo, and calcium or other insoluble phosphate added, whereupon a compact mass is obtained.  Instead of an insoluble phosphate there can be added other substances, such as kainite, silicates of potassium or magnesium, or fluorides, which are converted by acids into bodies of greater manurial value, or which by taking up water reduce the necessity for evaporation.ALSO:The process described in the parent Specification is modified by the use of acid salts for effecting the conversion of cyanamide into urea.

Abstract: 1460199 Bobbin tube loaders MASCHINENFABRIK RIETER AG 12 June 1974 [22 June 1973] 26029/74 Heading D1F A bobbin tube loader for ring-spinning machines comprises a mobile carriage with a vertical axis drum 15 and a horizontal axis drum 13, about which runs a chain conveyor 16 whose links have tube receiving recesses 17' which convey tubes from a supply chute 5, at the horizontal drum end, to the vertical drum end where they are deposited on tube receiving pins 21 aligned with the spinning stations, the pins also engaging a gearwheel 20 which drives one of the drums. The tubes are fed to chute 5 from containers 24, 24' mounted on a ramp 23. A guide 38 engages the lower end of the tubes during transfer along the carriage and a spring 40 urges them onto the pins 21. The working parts of the carriage are hinged at 10 to a subframe and flexibly mounted at the tube depositing end by a spring loaded elbow 30, 31, 32 which allows compensation for undulations of the floor.

Abstract: 745,583. Pneumatic conveyers. AMALGAMATED ROADSTONE CORPORATION, Ltd. Dec. 16, 1954 [Sept. 22, 1953], No. 26117/53. Class 78 (1). In means for discharging powdered materials e.g. cement, limestone and coal dust, from containers of the kind in which discharge is effected by admitting gas under pressure into the container to fluidize the material and is assisted by admitting pressure gas directly into the discharge pipe, the admission of gas into the discharge pipe is controlled by a valve which opens automatically when the pressure in the container reaches a predetermined value and closes when this pressure falls. The conical lower part 13, Fig. 1, of the container is made in two parts, the lower of which, 13<SP>1</SP>, has spaced walls 16, 17. The outer wall is of metal and the inner one of porous material, e.g. canvas, sponge rubber, latex foam or hair. The inner wall may be mounted between perforated metal plates. The upper part of the wall 17 is perforated and is encircled by a plate 18 of L-shaped crosssection. Gas is admitted to the chamber 19 formed by the plates 17, 18 through the branch 24 of a supply line 25. This line is connected also by readily detachable means to a pipe 21 disposed in the flared end of the discharge pipe 22. The flow of gas through the pipe 21 is controlled by a valve member 26, Fig. 2, carried by a stem 27 which is attached to a piston 29 working in the casing 21<SP>1</SP>. An extension of the stem below the plunger engages an abutment 30 for the upper end of a coiled spring 31. The lower end of the spring bears on an abutment 33 which can be moved by a screw 34. This screw is turned to vary the compression of the spring and hence the pressure keeping the valve member 26 on its seat 28. A conical skirt 23 mounted on the pipe 22 deflects falling material against the wall 16 to ensure a uniform flow into the pipe 22.
