Title: Improvements in and relating to gardening appliances
IPC: A01G29/00
Filed: 1956-10-12
Abstract: 813,759. Injecting fertilizers &c. HARRIS, W. J. Aug. 26, 1957 [Oct. 12, 1956], No. 31186/56. Class 6(2). A gardening appliance comprises a tubular element for insertion at its lower end into the soil, a reservoir to hold fertiliser in tablet or powder form, a reciprocable plunger which forces a prearranged charge of fertiliser from the lower end of the tube and means associated with the plunger to effect or control movement of the prearranged charge of fertiliser to the lower end of the tube. The tubular element 3, Fig. 2, contains a plunger 8 urged downwardly by a spring 9 to engage a pellet 16 held ready for ejection by spring 14 after passing from the reservoir tube 1 through the aperture 7. Spring 9 may be tension instead of compression and the lower end of the tube 3 may have a movable disc or plate which actuates the plunger when the disc encounters the soil on the appliance being forced into the ground. The rod 11 may then be omitted. Three modifications are described wherein firstly the reservoir comprises the upper part of the tubular element and the plunger comprises two movable springs which project inwardly through the side of the tubular element, secondly the tablets are pushed from the reservoir to the tubular element by an arm operated on reciprocation of the plunger and thirdly, the tablets are held suspended in the reservoir tube by two springs which are operated by the plunger to allow one tablet to fall to the bottom of the reservoir and into the tubular element on each reciprocation of the plunger. In a modification for use with powdered material, the reservior comprises a partitioned container 41, Fig. 13, surrounding the lower part of the tubular element 1. The spring loaded plunger 8 in the tube has an opening 47, which, when the plunger is raised, registers with openings 45 in the tube 1 so that the opening 47 receives a charge of fertiliser. On depression of the plunger, the opening 47 passes into the lower chamber of the container 41 and fertiliser passes through the other openings 46 in the tube 1 into this lower chamber, this fertiliser being forced out of the bottom of the tube 1 when the plunger again descends. Modifications of the appliance for use with powdered fertiliser include resilient seals around the holes through which the fertiliser passes and a plunger cut away so that when it is depressed the fertiliser flows freely from the reservior to the lower compartment which is then made adjustable in volume.

Title: Print impression mechanism
IPC: B41J2/24
Filed: 1954-10-29
Abstract: 764,620. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 29, 1954 [Nov. 2, 1953], No. 31288/54. Class 100(4) A print impression mechanism for recording characters on a record sheet R comprises a movable printer head 11 having a character pattern formed by the selective movement of a group of printing wires, a movable platen 30, and means for simultaneously moving the printer head 11 and the platen 30 towards one another to effect impression. As shown, the impression mechanism is applied to a wire printer of the kind described in Specification 729,064 in which printing wires 10 are displaced according to the setting of a control bar 22. All the sheaths 17 of the wires 10 are, at the printing end, clamped in a cam follower arm 24 so that once in each cycle they are moved resiliently by spring 42 towards the platen 30 which is formed by a resilient steel band attached to supports 33, 34 adjustably mounted on rods 36, 37 so that tension of the platen 30 may be changed. This platen is rapidlymoved towards the print head 11 five times - per cycle by means of a striker roller 26 carried on an arm 27 fixed to a gear 28. On the third movement the printing head 11 has reached printing position and the platen 30 is thus able to cause a rapid and intense printing impression to be made on the record R. The wires each have inertia slugs 13 and are frictionally held in a displaced position in the sheaths 17 so that the ends of the wires are automatically aligned during the impression stroke. Printing may be suppressed either by energization of magnet coil 43 which pivots a lever 46 into the path of end 47 of the arm 24, or by the manual activation of levers 48 so that a dog 50 enters a notch 51 in the arm 24.

Title: Process for the conservation of the pellicles of hydrate of cellulose
IPC: C08L1/06
Filed: 1923-12-14
Abstract: Dehydration of bottle capsules and other pellicles of cellulose hydrate is prevented, while permitting them to be stored in the dry condition without special precautions, by impregnating the pellicles in the hydrated condition with a solution of deliquescent and antiseptic substances.  A suitable substance is magnesium chloride applied in the form of a 40 per cent solution; but other deliquescent bodies may be employed, and to these an innocuous antiseptic may be added.  Capsules &c. so treated retain their capacity of shrinking or drying and after removal of the deliquescent substance; the removal is effected by soaking in water before applying them to the bottle.
