Title: Improvements in or relating to electric switch operating mechanism
IPC: H01H21/50
Filed: 1923-11-15
Abstract: 227,573. Igranic Electric Co., Ltd., and Bergmann, F. Nov. 15, 1923. Switches, quick-action.-In a switch-operating mechanism, applicable to circuits of multi-head machine drills, and of the kind wherein relatively slow movements of a controlling member in reverse direction are adapted to effect snap movements in corresponding reverse direction of a switch operating member, the operating member is free to move from one operative position to another when it snaps in one direction, but when it snaps in the reverse direction it is adapted to be prevented from returning to the former operative position by means of a releasable stop. As applied to a switch having forward, reverse, and neutral positions, the fixed contacts d, e are engaged by contacts a, c in the forward position, by a, e in the reverse position, and Fig. 3 shows the neutral position. The contacts a - - c are mounted on a shaft 1 having a crank 2 on the end of which is a pin 8 connected by springs 7 with lugs 6 on a control member 3. The member 3 is guided in a housing by means of rods 4, 5, connected to a device, which is driven under the control of the switch, and is provided with edges 16, 17 for engaging a roller 15 on the pin S. In the neutral position shown in Fig. 2, the springs 7 are to one side of the pivotal axis 1 of the crank 2 and the lathe is restrained against movement by a pivoted pawl 9 under the control of a spring 11. To start the device and move the switch to forward position, the crank 2 is released by the handle 13 oi the pawl 9 and the device starts up and moves the rod 4 and member 3 downwards until, just at, or before the deadcentre position, the edge 16 engages the roller 15 to positively move the line of action of the springs 7 past the pivot 1. The switch then rapidly snaps over to the reverse position and the device is driven in the reverse direction, moving the member 3 upwards until the edge 17 engages the roller 15 to move the switch back again. The switch is arrested at neutral position by the pawl 9. A handle 18 on the shaft 1 permits manual control of the switch. In the application of the device to a multi-head drill either or both rods 4, 5 are so connected to the drill-head as to be operable through the medium of a fast and loose rod, tappets or the like at any position in its travel.

Articles of rust-resistant or refractory steels, or of nickel or cobalt alloys, have surface diffusion alloys containing chromium and aluminium, and if desired silicon, formed on them by heating them with an ultrafine powder containing these materials in an alloy and having a mean grain size equal to one micron or less, with an oxide which acts as a chemically inert diluting agent and with a halogen, halogenide, hypohalogenite or a mixture thereof. Heating is carried out in a container which is closed but is not gastight and which is surrounded during heating by a hydrogenated atmosphere which may be of electrolytic hydrogen, of hydrogen and argon or of cracked ammonia. After heating the container may be cooled in a similar atmosphere, preferably by spraying with water. The ultrafine powder of chromium and aluminium alloy is preferably made in situ from chromium and aluminium powders which are heated together in a "blank" operation. Alumina may be used as the diluting agent and ammonium chloride or bromide (advantageously with some aluminium fluoride) is included in the mixture. Both chromium and aluminium may be replenished by adding aluminium powder on each occasion between treatments and some chromium from time to time. Heating is at from 750‹C. to 1200‹C., for not more than 20 hours. Prior to treatment according to the invention, the articles may be given a preliminary sheathing by tantalum diffusion, by heating with tantalum powder, alumina and ammonium chloride, or a preliminary sheathing by chromium diffusion. Nickel alloy articles, for example, may be heated with chromium, nickel, alumina and ammonium chloride, replenished with chromium and ammonium chloride or bromide.

Roller - and - ring mills; mills of unspecified type combined with sorting apparatus. - In an elevator arrangement for the feeding of coal 1 pulverizing mills, which mixes the raw coal and the material coming from the mill and supplies the mixture to a wind sifter arranged in advance of the mill, the connection of the wind sifter with the elevator is such that the material to be sifted is thrown from the elevator over the sifting chamber directly into the sifting air current, and the elevator is also within the sphere of action of the. air current. The coal to the mill c is fed by a hopper h and conduit f to the bottom of a casing b, from which it is raised by an elevator a and discharged into a wind sifter i through an opening in the top of the casing b. The coal enters the mill through a pipe p and is discharged through a pipe d to the bottom of the casing b where it mixes with the raw coal from the hopper. A blower K draws air from an opening n in the sifter through the raw and pulverized coal discharged by the elevator onto the plates m. This air, laden with coal dust, passes through a conduit between the .casings b, i, to the blower, from which it is discharged through a pipe s. Air and coal dust are .also drawn up through the casing containing the elevator and combines, at the top of the elevator, with that drawn through the, sifter i. In a modification, a hood, open at the bottom and communicating at the top with the suction side of the blower, is placed near the bottom of, and between the runs of the elevator so that air is drawn through the sifter and elevator casing before being discharged by the blower. In a further modification, the air is diverted by conduits into two parts, one passing upwardly through the sifter and the other passing upwardly through the elevator, the two currents meeting at, the top of the elevator to be discharged through the blower similarly to that shown in the Fig.
