Title: Improvements in or relating to methods of and means for drying fodder-plants
IPC: A23K30/12
Filed: 1937-10-21
Abstract: 503,964. Drying grass &c. JENNY, H. Oct. 21, 1937, No. 28724. Convention date, Oct. 21, 1936. [Class 34 (ii)] In apparatus for drying grass by circulating a mixture of combustion products. and air through it, the hot gases and moisture are drawn from a drying chamber K, Fig. 1, through conduits 10 which heat fresh air drawn into the space around the conduits by a fan V2 and supplied, under the control of a temperature regulator R, partly as combustion air into the furnace O from which the combustion gases are taken and partly into the gases. Grass bales are passed along a table 3, Figs. 2 and 4, in a drying chamber surrounded by a casing 2 divided at the bottom by transverse partitions forming compartments a<1> . . a<5>, which contain fans 6 circulating the combustion products and air transversely through the bales. The fan V1 drawing the products and air from the part of the chamber above the centre compartments a', a<3>, a4, discharges into the part of the chamber above the first compartment a', and fresh air circulated in the part above the last compartment is drawn by the fan V2 through an aperture 1a in the chamber walls into the casing 2. In a modification the grass passes through a rotary drum having stirring prongs, and the mixture of combustion products and air enters -the compartments a<1>, a<2> through boxes with bottom discharge opening and provided with electric or other heating elements. The grass may be first treated in a separate rotary drum traversed by the gases from the main drum. The Specification as open to inspection under Sect. 91 also describes apparatus in which fresh air is drawn through a preheater and forced by a blower through a drier, and is then circulated through the drier and a heater by a blower of greater capacity than the supply blower. Part of the foul air drawn from the drier is returned to the fresh air supply and part is forced through a second drier. The two driers may comprise rotary drums mounted on a common shaft.

Patent GB-193903-A (GB)
Title: Method of and device for separating suspended particles from electrically insulating fluids more particularly gases
IPC: B03C3/68
Filed: 1921-10-29
Abstract: In the method of precipitating suspended particles from gases, &c., described in Specification 17840/12, means are now provided for extinguishing arcs or sparks before damage can ensue.  For this purpose there may be used a high-pressure resistance, either solid, liquid, or gaseous, and preferably such as increases with increasing current.  Metallic resistances having a positive resistance-temperature coefficient are suitable.  Alternatively, there may be provided ionized-gas gaps or vacuum tubes in which the resistance increases with the current, and particularly vacuum tubes having a limited current capacity which is less than, equal to, or slightly higher than the current necessary for sustaining a permanent arc in the precipitator.  Parallel groups of electrodes as described in Specification 19733/13 may be supplied with separate arc extinguishers.  The number of electrodes connected in parallel in each group must be such that the total working current p  is less than that required by a permanent arc in the precipitator or in the auxiliary spark-gap; the working current may be one-third of the latter current.  In determining the current value at which an arc becomes stable, there is used an ammeter, or optical or acoustical indicator, e.g. a special discharge gap or a number of vacuum tubes, if necessary with a parallel resistance. In some cases the spark-gaps or discharge tubes acting as resistances, or the gaps of a high-tension rectifier in the supply circuit, give sufficient indication of the current.  Different minimum values of current for a stable arc are obtained with increasing and decreasing currents.  The former value is lower and is preferably taken as the limiting value of the working current of a group; it may be 0.1-0.2 ampere.

Title: Improvements in rotary switching mechanisms
IPC: H01H9/26
Filed: 1929-09-24
Abstract: 336,759. Johnson, F. R. Sept. 24, 1929. Controllers, controlling extent of travel.-A main motor 85 is controlled over contacts 66 - - 69 bridged by arms 35, 36 when a shaft 34 is given a quarter revolution with a snap action motion. Closure of a control switch 84 causes an auxiliary motor 32 to rotate a shaft 24 and strain a spring connecting the shafts 24, 34, and thereafter depress a locking lever 42 so as to permit the quarter revolution, the lever being retained depressed by a no-volt coil 60. At auxiliary contacts, the motor 32 maintains its circuit, thereby again straining the spring so that the main contacts 66 - - 69 can be opened by a further quarter revolution of the shaft 34. When the no-volt coil 60 is de-energized, during the straining motion, resistance 55 in circuit with the main motor 85 is gradually cut out, and at the end of the straining motion the auxiliary motor cuts itself out of circuit. By suitable arrangement of the main contacts the switch device can control an induction motor, either through star-delta or tapped transformer connections. Also rotation of the auxiliary motor after the main motor has been started can be under the control of a master controller through follow-up contacts, so that the resistance 55 is cut-out as required. By controlling the no-volt coil through an overload relay, an overload circuit breaker is obtained, that can reclose a predetermined number of times by the action of vanes, 77 on projections from the piston rod of a dashpot 74. If the piston rod reaches its highest position before the circuit-breaker remains closed, it operates a lock-out switch and so prevents further attempts being made. Instead of " no-volt " retaining coil 60 being used a normally de-energized coil can be used to trip a latch and release the locking lever.

Abstract: 248,460. Kephart, A. T. Dec. 3, 1924. Forming articles from tubular blanks.-A machine for shaping the ends of tubular glass blanks, in the manufacture of phials and like receptacles, comprises means for moving a blank in a direction at right-angles to its axis from a magazine to a stationary position, means for rotating the blank in this position and for subjecting one end to a preliminary heating, means for moving the blank, in the same direction as before, to another stationary position where it is rotated and its hot end subjected to intense heating, and mechanical devices for shaping or necking the hot end. The tubes 2 are stored in an inclined magazine 30, and they are released one at a time by gates 37, 38 which are withdrawn alternately and allow a tube to roll on to a carrier 9. The carriers are attached to parallel endless chains 10 which pass around sprocket wheels 5, 6, and the movement of the chains first conveys a tube to a position above a heating-burner 12. At this position the tube is supported by pairs of rollers 14, 15, and a roller 13 makes contact with the tube and rotates it while one end is subjected to a preliminary heating by the burner 12. The roller 13 is inclined to the direction of movement of the tube, so that the tube end is forced against a stop 20 and is held against displacement in the direction of its axis. After the preliminary heating, the rollers 14, 15 and the roller 13 are moved apart, and the chains move the tube to the next stationary position where it is again supported by rollers 17, 18 and rotated by a roller 19 as before. In this position, the hot end of the tube is further heated by burners 21, 22. When the glass is plastic, a plug 25 moves into the end of the tube and dies 23, 24 are closed on to it, and the dies, and plug together form the end of the rotating tube to the desired shape. After removal of the plug and dies, the chains 10 move again and the finished tube is discharged from the machine.
