Title: Improvements in or relating to the treatment of seed
Inventor: RABINOVITCH HAVVA
IPC: A23K1/16
Filed: 1960-02-09
Abstract: Materials e.g. physiologically-active materials are introduced into seed, particularly bird seed, by splitting the seed husk by means of hot water or steam, treating the split seed with a solution or fine suspension of one or more of the materials to be introduced and causing or allowing the treated seed to dry. Materials mentioned are: Vitamins A, B1, B12, D and E, the vitamin B complex, penicillin, chloramphenicol, furazone, mandelamine and drugs generally. According to an example, 12 g. of canary seed was added to 25 ml. of boiling water, boiling being continued for 10 minutes; the seed was then separated from the water and dried at a temperature not exceeding 50 DEG C.  The dried seed was added to 96 % ethyl alcohol and sufficient of a concentrated solution of Vitamin B1 in 96 % alcohol was added to give approximately 1 mg. of vitamin for each 100 g. of seed.  After standing for 24 hours, the alcohol was decanted off; residual alcohol in the seed was removed either by allowing the seed to stand in the air or by the application of vacuum.  In an alternative procedure for splitting the seed husk, 12 g. of canary seed was supported on a perforated disc placed in a vertical cylindrical vessel through which steam was passed for from 10 to 15 minutes, the seed being then removed.

Title: Improvements in and relating to ignition magnetos
IPC: F02P1/00
Filed: 1919-02-24
Abstract: 143,614. Marks, E. C. R., (Splitdorf Electrical Co.). Feb. 24, 1919. No Patent granted (Sealing fee not paid). Magnetos, driving.-In an arrangement of the type in which an ignition magneto rotor is driven from an internal-combustion engine by means of a connecting helical spring, and the rotor for starting is turned in the reverse direction by a manually-operated pawl, a movable device is provided to hold the pawl out of engagement with the rotor during return movement to its normal position and while it remains in that position. As shown, the element 1, fixed on the rotor shaft 2, and the driving-member 5 are connected by a spring 6, a buffer spring 7 being also provided. For starting, a pull on the cable 16 causes a ring 8 to rotate on a frame 9 on one of the end plates of the magneto against the pull of a spring 13, and engages a pawl 17, pivoted on the ring 8, in one of a series of notches on the element 1. thus rotating the latter, with the shaft 2, in the reverse direction so as to compress the spring 6. The pawl is withdrawn from engagement by means of an incline z, Fig. 8, on a stationary ring 20, and the rotor flies. back to cause the initial spark. The pawl is normally held out of engagement with the notches by the end of a metal friction ring 10, which lags behind but is pushed round by a screw-head 19 on the ring 8 to follow the pawl as it rotates the element 1 in the reverse direction, and is moved back by the pawl as the ring 8 returns under the influence of the spring 13 to take up the normal position. To prevent undue stretching, the spring 13 is given a gradually increasing diameter at the part that encircles the ring 8.

Abstract: 998,249. Gearing. K. ZUSE. Jan. 31, 1962 [Feb. 2, 1961; Feb. 3, 1961; Sept. 20, 1961], No. 4640/65. Divided out of 998,248. Heading F2Q. An output shaft is driven at substantially constant speed by two Geneva mechanisms. As shown in Fig. 1, a driving shaft 1 carries a disc 3 with coupling bolts 4 axially slidable therein and which are alternately slidable to the left and right to engage in the slots of a pair of Geneva wheels 5 which are fast with bevel side wheels 6 meshing bevel planets 11 mounted on a carrier 11a fast with an output shaft 2. An actuating mechanism 9 has a cam arrangement 9b which in the full line position shown engages pins 12 on the coupling bolts 4 to shift the bolts alternately to the left and right to engage the Geneva wheels to drive the driven shaft. In the raised, dotted line position of the actuating means 9 the cam is out of the path of the pins 12. When one of the coupling bolts is shifted to engage the respective Geneva wheel 5, it also engages the end of a stop lever 8 to raise it out of engagement with a stop disc 7 which is fast with that Geneva wheel so that the Geneva wheel is free to rotate. If the control means 9 is still in its operative position the next coupling bolt 4 is shifted in the opposite direction to engage the other Geneva wheel 5 and also to remove a locking lever 8 from a notch disc fast with that Geneva mechanism. A stationary control means 10 is provided for returning each extended coupling bolt to its inner position after it has disengaged a slot of one of the Geneva wheels. If it is desired to rotate the output shaft in reverse a second driving shaft, rotating in the opposite direction to the shaft 1 may be provided together with the necessary coupling bolts and actuating mechanisms to provide this reverse rotation. Fig. 5 shows a modification in which the Geneva wheels 5 are interconnected by way of a cranked lever 21 which is rotatably mounted in a disc 20 fast with the output shaft 2 and which rotatably engages apertures 50, 51 in the Geneva wheels.

In a mechanical stoker in which a movable scraper coacts with the discharge end of a travelling grate a plenum chamber is disposed beneath the grate and the wall of the chamber at the grate discharge end terminates at its upper end in a substantially horizontal surface upon which rests the ash discharge section of the scraper. As shown applied to a mechanical stoker (Fig. 1) in which a ram 16 and impeller. 18 feeds fuel on to a travelling grate 10 a plenum chamber 50 is disposed beneath the grate the end wall 51 terminating at its upper end in a horizontal surface 69. The scraper 57 (Fig. 4) comprises two integrally formed portions one 58 (the ash receiving portion) adapted to rest upon the grate bars and the other 59 (for ash discharging) adapted to rest upon the surface 69. The connection between the portion 59 and the surface 69 is a seal assembly 73 of the floating type constituted by the interengagement of plates 71 and slots 72 such a seal allowing reciprocation of the entire scraper in a direction parallel to the direction of travel of the grate. This reciprocation is effected by oscillating a shaft 67 which by means of arms 66 and links 62 is pivotally connected to the scraper. Means for oscillating the shaft 67 (Fig. 2) comprises a double-acting piston shaft 76 which is connected to the shaft 67 by an arm 92 and is mounted concentrically in a housing 77 which has a large chamber 78 and a small chamber 79 separated by a plate 81. Hydraulic operating fluid at a constant pressure is alternately supplied to each chamber and the speed ratio between the forward and rearward movement of the scraper is dependant upon the effective face areas of the pistons 82, 83 within the chambers 78, 79 respectively. In the embodiment shown movement of the shaft 67 also operates the travelling grate. The speed ratio between the movement of the scraper towards the oncoming ashes and the movement away from same is about 5 to 1.
