Title: Improved rotatable duplicators with automatic feeding of paper
IPC: B41L39/06
Filed: 1951-05-02
Abstract: 707,306. Feeding sheets. RITZERFELD, W., and RITZERFELD, G. May 2, 1951 [May 2, 1950], No. 10302/51. Class 100 (1) Pile supports; sheet separators.-Single sheets are automatically separated from a pile and fed to a rotary duplicating machine by apparatus which comprises a member which forms a bulge in the uppermost sheet of the pile and subsequently begins feeding the sheet towards the printing drum ; the bulge-forming member is controlled by a movable element depending on the rotation of the printing drum. The pile of sheets 20 is supported by a platform 19 which is movable in a frame 17 under spring action so that initially the pile is pressed against one holding member or rod 39 carried by the frame 17. As the printing drum 1 rotates, associated cams 2, 3 act on a forked lever 6 to move a link 8 and cam disc 11 which acts on a bell-crank lever 14 carrying the record holding member or rod 15 so that the latter is pressed down on to the pile sufficiently to move it away from the holding member 39. A second cam disc 12 coaxial with and linked to the disc 11 by a pin and slot connection 21, moves with the disc 11 after initial lost motion and, through an associated radial arm 23, links 24 and 28, and arm 30, causes shaft 31 to rotate within the roller 34 to the position shown in Fig. 2. The motions of the lever 6, link 8, cam disc 11, and, after a short interval, the second cam disc 12 are then reversed. The shaft 31 and roller 34 are caused to rotate and move the top sheet so that it buckles between the roller 34 and holder 15, and its rear end is no' longer under the holder 39. The cam disc 12, which during the reverse motion initially holds the lever 14 in the position shown, then releases that lever and allows the holder 15 and pile 20 to rise until the rear end of the pile is pressed against the holder 39. The holder 15 then releases the front of the top sheet, which is driven further forward by continuous movement of the roller 34 until it is gripped by the printing machine. The roller 34 and its shaft 31 are carried by a lever 33 pivoted at 35 and acted on by an adjustable spring 36. Movement of the table 19, which may be covered with rubber &c., is guided by pins projecting through slots in the frame 17. A spring 38 acts, through a linkage including bell crank levers x3, x4, to resist downward movement of the table. To enable the distance between the holding rod 15 and the roller 34 to be adjusted according to the stiffness of the paper, each end of the rod has a pinion engaging in a slot in the end of the bell-crank lever 14. One side of the slot has teeth engaged by the pinion teeth. Plates through which the rod passes can be clamped to the levers to hold the rod in the adjusted position.

Patent GB-105578-A (GB)
IPC: C05C7/02
Abstract: 105,578. Sinclair, G. W., and Nitrogen Products & Carbide Co. March 16, 1916. Calcium cyanamide.-In the granulation of calcium cyanamide, the necessary water or watery solution is added in more than one operation, the temperature during the second or final operation being maintained lower than in the first operation. During the first addition of water the heat liberated by the reactions such as the decomposition of calcium carbide and the slaking of lime is allowed to raise the temperature sufficiently to ensure the reactions being effected rapidly but not high enough to cause the evolution of ammonia, a temperature above 60‹ C. being suitable. The material may then be cooled and may be diluted with solid matter inert to water, for instance calcium cyanamide dust which has passed through the whole process, after which the second addition of water is made, the temperature being limited so as to be lower than that attained during the first addition. The semi-plastic material is formed into flakes or small pieces by mechanical means such as compressing-rollers, and is then dried, with regulation of the temperature. During the drying it is desirable to keep the material in uniform motion, for instance by using horizontal or inclined rotary cylinders. Some dust may be produced, but if the drying is effected in a moist atmosphere, conveniently generated from the mass itself, the dust to a large extent adheres to the granules or forms small aggregates which eventually form granules. It is therefore desirable that the apparatus should be more or less closed to preserve a moist atmosphere.

Title: Method and means for protecting seeds during their initial stages of growth
Inventor: PEAK JOHN WALTER DENNIS
IPC: A01C1/04
Filed: 1970-03-05
Abstract: 1278529 Protecting seeds J W D PEAK 25 May 1971 [5 March 1970] 10609/70 Heading A1E [Also in Division B8] A method of protecting a seed during its germination and initial stages of growth comprises locating the seed in an environment of either Balsa wood or of balsa wood dust or chippings bound by a suitable binder or adhesive. In the latter case the binder is preferably water soluble so that the cellular structure of the wood is not sealed and water can reach the seed. Small seeds, as used in horticulture or agriculture, may be enclosed in Balsa wood dust bound with water soluble binder; large seeds, as used in silviculture may be surrounded by wood chippings, and in this case the binder need not necessarily be water soluble since the chippings are of sufficient size to allow water to reach the seed. Alternatively, a rectangular slab of the wood (or which can be formed from wood dust and/or chippings) may be employed, the seeds 15 being placed in holes 14 of the portions 8. The seeds remain dormant until the slab is moistened and germination commences. In the initial stages the roots may grow through the slab and at a later stages the whole slab or one or more of the individual portions be planted in the soil The Balsa wood dust or chippings can have fertilisers, fungicides, insecticides or other growth promoting or seed protecting substances mixed with them before being bound; the Balsa wood may be impregnated with these substances.
