Title: Process and apparatus for the utilization of the combustion gases from rotary cement burning kilns
IPC: F27B7/36
Filed: 1922-12-04
Abstract: 212,298. Jorgensen, M. Vogel-, Ronne, E., and Middleboe, K. Dec. 4, 1922. Rotary kilns; waste gases, utilizing. - In a rotary cement kiln to which the raw material are fed in a wet state, a part of either the hot gases or of the raw materials is kept separate from the remainder in the drying and preliminary-heating zone so that a part or the whole of the hot gases will leave the kiln in a better state for subsequent utilization, for example in steam-generating plant. In the apparatus shown in Fig. 1 the drying-zone of the kiln is subdivided into a central flue 2 leading to a dust chamber 4, steam generator 8, economizer 9, and exhaust fan 10, and four outer chambers 5 leading in the ordinary manner to the stack flue 12. The raw materials are supplied through the chambers 5 only, and thus the hot gases which pass to the steam generator are kept free from moisture. The chambers 5 are preferably spaced from one another and from the flue 2 by passages to which the air has access. The flue 2 may be stationary instead of being formed to rotate with the kiln, and the. heating value of the separated gases may be increased by mixing fuel therewith. In the plant shown in Fig. 4 a portion of the wet material to be burnt is fed to the kiln 1 at its inlet end through the duct 13<1>, while the remainder in a dry state is fed in at the end of the drying-zone through the stationary chamber 21. The hot gases leaving the kiln are utilized first in the steam-generating plant 8 and then for drying the second portion of the raw materials in the drum 17.

Title: Process and an installation for the industrial production of plants
IPC: A01G31/04
Filed: 1976-08-11
Abstract: 1512606 Treating plants O RUTHNER 11 Aug 1976 [5 July 1976] 33483/76 Heading A1E Seed is germinated in a first chamber in boxes arranged in stacks, and the resulting root fleeces are transferred to a conveyor in a second chamber which provides an environment favourable to shoot formation. Boxes 10, with or without a substrate, are loaded with seed from a hopper 1 and are arranged in stacks; the stacks are put in a chamber 4 having air inlet ducts 12 and extraction ducts 13 at opposite sides of each stack. and nozzles 14 for intermittently spraying nutrient solution. Excess nutrient solution gathers on the floor of the chamber and collects in a channel whence it is recirculated. As shown the chamber 4 is divided into sub-chambers 4A, 4B each housing two stacks. Sub-chamber 4A serves for pre-germination, the stacks are then moved to sub-chamber 4B and the spacing between the boxes of a stack increased and light sources 30 introduced. The seeds, together with a substrate if present, then form a coherent root fleece. The stack is then removed from the sub-chamber 4B and placed on a platform 15 which is slowly lowered. As the boxes register with a roller 17 they are projected forwardly to bring the root fleece into contact with a gripping roller 18 which removes the fleece from its box and places it on a conveyor 16. The conveyor 16 feeds the fleece to a carrier 28 of a conveyor 6 in a chamber 5, the conveyors 16, 6 being driven in timed relationship to correctly position the fleece on the carrier. Nutrient solution is sprayed onto the fleeces through nozzles 29 and illumination is provided by lights 31 to encourage the formation of shoots. With seed such as barley the entire process takes about eight days. The boxes are of shallow tray-like form and have one side omitted to facilitate the extraction of the root fleece by the roller 18. The lower part of opposite sides of a box may be inset from the upper part to facilitate stacking of the boxes and to guide longitudinal movement, and a toothed rack may be provided on the bottom of the box for engagement by the roller 17 which is formed as a pinion.

Abstract: 432,622. Pencil holders. ANGLO PENCIL CO., Ltd., Bank Chambers, Pelham Street, Nottingham. Nov. 23, 1934, No. 33753. Convention date, Dec. 13, 1933. [Class 146 (iii)] In a propelling-pencil of the type in which the lead is propelled in short steps by pressure upon a knob at the rear end of the pencil, there is provided a longitudinal cavity which in section resembles two parallel tubes communicating with each other along their length, one of which contains the lead and guides it to the tip of the pencil, while the other contains a wire or rod formed with teeth and reciprocatable in the tube by pressure upon the end knob to which it is connected, the teeth being engaged by a pawl-like part extending from a lead pusher which is situated in the lead guide tube. The pencil holder 1, which may be of wood, synthetic resin, or other material is formed in one piece or in two pieces joined along their length and has a longitudinal cavity 15 of the shape referred to, in which may be enclosed twin tubes 2, 3, having a communicating passage 13 between the tubes. The groove 15 extends obliquely so that the tube 2 which is concentric at the front end with the tip 5 is eccentric at the cap end, while the tube 3 becomes concentric with the holder at the cap end. A pusher wire 6 having an enlarged front end is caused to move forward in the tube by a toothed rod 4 with which the bent end 20 of the pusher engages by passing through the passage 13, the pusher being held frictionally against backward movement. The rod 4 is connected to the end knob 9 so that pressure thoreon moves the rod forward to advance the lead, the return movement being effected by a spring 8. The amount of longitudinal movement of the knob 9 is limited by a projection 26 on a tube fitted on the end of the holder which engages a longitudinal slot 23 in the knob. The slot 23 is provided with an extension in the form of an inverted U, which permits the cap and rod 4 to be rotated when the knob is in its forward position, so as to bring the teeth 16 of the rod 4 out of engagement with the pusher so that it and the lead may be pushed back into the holder 1. One limb of the U-shaped extension slot is left open so that the knob 9 and rod 4 may be removed. The inner side of the metal tip 5 may be ribbed to prevent rotation of the lead and the end 17 may be split.

The individual springs are then reheated in a furnace and fed to a/or one of a pair of punch and die sets 31, 32 for hole punching. The band and springs are fed through the apparatus on a roller table 20. The furnace 21 heats the band to 900‹ C. The rolling mill 22 has working rolls 23, 24 and pinch rolls 25, 26. The separation of the working rolls 23, 24 is effected by a screw down mechanism 44, Fig. 6, controlled by a pulse motor 43 fed with signals from a logic circuit 42. The logic circuit stores information of desired taper lengths (l 1 ), (l 2 ), Fig. 7 (not shown), spring length (L), spring thickness (T) and front end thickness (t 1 ). These features of each spring are measured by the pinch rollers 25, 26 connected to pulse generators 40, 41a, 41b. whose signals are fed to the logic circuit 42. The measured valves are processed in dependence on the desired values and the output signal is applied to the pulse motor 43. The rolls 25 and one roll 26 serve to measure the length passed between them while the other roll 26 measures the thickness of the band. The ends of the leaf spring produced may have linear or curved tapers on one or both faces, Figs. 9A-D, 10A-D (not shown). The tapers may be symmetrical or assymetrical.
