Title: Improvements in or relating to electromagnetic switch operating mechanism
IPC: H01H50/24
Filed: 1955-01-20
Abstract: 790,371. Electromagnetic switches. IGRANIC ELECTRIC CO., Ltd. Jan. 20,1955 [Feb. 10, 1954], No. 1745/55. Class 38 (5). Mounting brackets 31 of an armature 3 have split end portions 31a, 31b forming bearing surfaces engaging a pivot pin 23, the armature being releasably held on the pin by a spring- biased plate 51 having knife-edges 52 cooperating with hook-shaped ends of the portions 31b, the biasing spring 59 acting between a depending limb of a bracket 62 and a washer 58 retained on a neck portion 56 of an extension 55 of the plate 51. The plate 51 slides to-and-fro upon normal movement of the armature relative to the core 2 and is guided by the enlarged end of the depending arm 61b of a bracket 61, the arm 61b extending through a cut-out 54 in the plate. During the normal armature movement the sides 54a, 54b of the narrow portion of the cut-out 54 co-operate with a narrow portion of the arm 61b, and to remove the armature the plate 51 is pulled forward so that shoulders 54c of the cut-out may be latched against a wider part of the arm 61b thus permitting lifting of the bearing portions 31a, 31b from the pin 23. To prevent inadvertent release of the armature a further neck portion 57 of the plate extension 55 is normally held by a spring 63 in the vertical limb of an inverted T-shaped slot 62b (Fig. 3, not shown) formed in a further limb of the bracket 62. The arrangement is such that the broader end of the extension 55 abuts the bracket 62 before the arm 61b leaves the narrow part of the cut-out 54, release of the armature requiring movement of the extension 55 against the bias of spring 63 so that the extension enters the horizontal arm of the slot 62b. The switch contacts are not shown in the drawings.

Title: Improvements in or relating to method of dehydrating gelatin capsules and apparatus for carrying out said method
IPC: F26B25/18
Filed: 1956-01-20
Abstract: 797,906. Drying apparatus. SCHERER CORPORATION, R. P. Jan. 20, 1956 [April 18, 1955], No. 1970/56. Class 34(2) Sealed gelatin capsules containing pharmaceutical products, e.g. vitamins, are dried by exposing them to radiation of wave length from 9000 to 15000 A.U's. from infra-red lamps and at the same time to a current of relatively cool air to maintain the temperature of the gelatin below the softening point and so prevent them from sticking together. The capsules are fed from a hopper 86, Fig. 1, into the first of a series of rotary drums 10 of foraminous material, supported upon rollers 34, Fig. 6, mounted upon shafts 14, 16 driven through belt gearing from an electric motor 36, and pass in turn through the succeeding drums from the last of which they are discharged through a shoot 87 to a collecting container. The drums are disposed in individual compartments 18 formed by partitions: 28, Fig. 4, and communicate with one another through apertures closable by doors 20, Fig. 5, mounted on shafts 21 rotatable by solenoids 35 actuated at intervals by a timing mechanism. Each compartment is heated by infra-red lamps 60, Fig. 3, supported by a partition 24. Air having a temperature not exceeding 120F. and a humidity of less than 40 per cent is passed in series through the compartments by fans 72 mounted upon a common shaft, the first fan having an inlet 71 from the room in which the apparatus is housed or an airconditioning plant and an outlet nozzle 30a opening into the first compartment, while the succeeding fans have inlets connected to apertures 24a in the corresponding partitions 24 and outlet nozzles 30a. The air from the penultimate compartment may be directed either to an outlet shaft 24 or through a nozzle into the last compartment into which air from the room may be drawn through a perforate cover 26. Air from the penultimate compartment may be returned to preceding compartments by a fan 66 discharging into a duct 62 having apertures 61 opening into the compartments and controlled by dampers 67. The nozzles 30a open into the compartments at such an angle that whenever a door 20 is opened the capsules are transformed pneumatically from one drum to the next. In the normal operation of the apparatus, a batch of capsules is fed into the first drum and after retention therein for a predetermined interval is tranferred to the second drum by the automatic opening of the door between the drums. Upon closure of the door a fresh batch of capsules is fed to the first drum and after a further interval of time the contents of the second drum are tranferred to the third, the contents of the first drum being tranferred to the second and upon closure of the door separating the first and second drums the former receives a fresh batch of capsules. As the operation proceeds all the drums eventually contain capsules. By locking doors 20 in the ooen position, the capsules flow through the drums in a continuous stream.

Title: Apparatus for coking powdered coal and like hydrocarbonaceous fuel
IPC: C10B49/08
Filed: 1934-01-19
Abstract: 417,555. Carbonizing-apparatus. DORNBROOK, F. L., 4426, North Farwell Avenue, and DREWRY, M. K., 3019, South Shore Drive, both in Milwaukee, Wisconsin, U.S.A. Jan. 19, 1934, No. 1984. [Classes 51 (i) and 55 (i).] Powdered coal, preheated and oxidized in the presence of flue gases in a chamber 8 is fed to a separator 23 for removal of the gases before passing, in a substantially static mass, to a carbonizer 21, the resulting powdered coke being fed if desired directly to a furnace 11. Gases from the furnace, preferably at a temperature of 600‹ F., may be used in the preheating stage, and intimate contact with the fuel particles in the chamber 8 is ensured by a paddle 13. The separator may be of the cyclone type and the flue gases herein may be returned to the furnace. The rotary feeder 28 of the separator is a close fit in the discharge pipe to allow static masses of the material to be fed to the carbonizer. In a modification, the oxidizing chamber and the separator may be combined in a single chamber. The oxidized fuel is carbonized in the chamber 21 in thin films, between closed envelope-like heating elements 29, attached to inlet pipes 30, through which flue gases flow from the furnace. Baffles 32, 33 in the envelopes give a zig-zag flow to the heating gases. Gas obtained from the distillation is collected from screened off-take pipes 34 projecting into the fuel mass and the powdered coke, at a temperature of about 1000‹ F., is introduced into the furnace by the feeder 38. Caking of the fuel to be treated is prevented by ensuring that a large proportion of fine particles are present in the mixture so as to coat the particles of larger size.
