Title: Improvements in and relating to volumetric measuring and dispensing devices for granular and powdered materials
Inventor: EVANS BERNARD JAMES REUBEN
IPC: A01C15/02
Filed: 1950-05-23
Abstract: 678,859. Powder distributers. IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 23, 1951 [May 23, 1950], No. 12873/50. Class 18. [Also in Group XVIII]. A device for supplying measured quantities of powdered fertilizer in the vicinity of plant roots comprises a container 1 having a nozzle 9, a hand-operated spring-loaded plunger 6 with a reduced portion 16 which expels the quantity of material contained in the bore 12 of the nozzle, and a member 8 which rides on top of the material in the container until the material is exhausted, when a spring- loaded stop 20 engages under the shoulder at the top of the reduced portion 16 and prevents it from entering the nozzle. Tread plates 10 are provided on the nozzle to assist in forcing it into the soil. If the material is sufficiently self-packing and requires ejection, the quantity measured may be varied by restricting the plunger stroke by means of packing 30. To refill the container, the nozzle is removed, a tubular tool is fitted over the reduced portion to retract the stop 20 and the member 8 is allowed to fall back to the top of the container.

Abstract: 591,329. Moulding processes. STONE & CO., Ltd., J., and HODGES, E. F. May 25, 1945, No. 13101. [Class 83 (i)] A method of producing dies for use in casting and moulding operations comprises forming an accurate metal pattern of the object to be produced by the dies, and using the pattern in two or more successive casting operations for the successive casting of the die part, directly, from such pattern, the casting of one part being performed on or against another part. A pattern a, a<1> is partly embedded in sand b in a mould box c, the upper surface of the sand is formed with dowel depressions d and the surfaces of the sand and pattern are sprayed with a suitable dressing. An upper mould box f containing sand shaped with a cavity g corresponding to the outer shape of the required die part is placed on the lower box c and the die part h is cast.

Filed: 1924-05-30
Abstract: 223,836. Chatwood Safe Co., Ltd., and Bruckshaw, H. S. May 30, 1924. Locks, preventing release by destruction; seal fastenings.-In a safe or strong-room door lock in which a blocking slide, controlled by locking mechanism, engages the bolt tail to lock the bolt, a spring plunger, normally held retracted by a projection on the lock cover-plate, is provided to retain the slide in its blocking position, without movement of the slide, if the cover plate is blown away in an attempt to burgle the lock. The slide e controlled by the locking mechanism f blocks the bolt, which slides in the casing at right-angles to it. A plunger c pressed outwards by a spring is normally held retracted by the projection b on the cover-plate a. If, in an attempt to force the lock by explosives, the cover-plate is blown away, the plunger shoots forward into the recess d in the slide and retains it in its operative position. A lead or similar seal h prevents access to the screw g so that the plunger cannot be retracted until the seal is removed.
