Abstract: 140,366. Beyer, H. M., (Assignee of Friedrichs, W.). March 14, 1910, [Convention date]. Clutches, friction. -In electromagneticallyoperated segment friction clutches for use with machine tools, motor-boats, mining and mill machinery, &c., current is required only during engagement and disengagement, and the segments are operated by link-work or other transmission gear and are locked in engaged position. The core p of an electro-magnet o turning with the clutch segments b is secured to a bar q in which screws an adjustable sleeve r carrying a spring- pressed pin t bearing against a. lever k which turns on a pivot l and operates toggle-lings d to engage the segments b with the drum a against the action of a spring i. On excitation of the magnet, the clutch is engaged, and a spring catch y on the lever k locks behind an abutment 4 on the magnet casing. When the magnet is de-energized, the core p moves outwards by centrifugal action, and the pin t is pressed by its spring to move one arm of a lever u on the bar q into the path of a lever v on the magnet frame, so that when the magnet is again excited, a pin w carried by the lever v disengages the catch y from the abutment 4, and the clutch is disengaged by the spring i when the magnet is again demagnetized and allows free movement of the lever k. Air trapped between the magnet o and core p escapes through a passage z in a rod 1 and through a hole 3 which is so controlled by a screw 2 that the rate of movement of the core p may be controlled. To adjust for wear &c., the magnet o is so mounted as to be adjustable along the arc or the chord of the arc struck out by the catch y during rotation of the lever k.

Title: Improvements relating to the removal of the cerealin from grain
IPC: B07B1/24
Filed: 1926-10-15
Abstract: 259,989. Steinmetz, S. Oct. 19, 1925, [Convention date]. Hulling and decorticating; treatment by damping; treatment by heating; treatment with solid substances.-To remove cerealin, grain, moistened with water, is forced by a screw conveyer 1 through the spring closed door 2 of a casing 3 into a drum 4 provided with a perforated bottom 5 through which the free water can escape. The grain is carried into the drum 6 where it is acted upon by recessed beater bars 7 carried by a rotating shaft. The drum 6 is closed and its outlet is weighted or spring-pressed so as to maintain a large charge of grain in the drum. The friction due to the movement of the beaters causes the damp grain to become lukewarm and the outside laver of cellulose and the cerealin are loosened. The grain escaping from the drum 6 enters a peeling drum 9 in which the hulls are rubbed down and the husks removed by suction ventilation. The outlet of this drum is also spring-controlled and the heat generated by the rubbing action assists in drying the grain. The grain is washed in a separator 11-the water in which mav be mixed with chalk or other product not injurious to health-and then passes through an aperture 14 into a polishing drum 13 having rotary beaters 16. The polishing drum is connected to an air suction device and is closed by a spring-pressed outlet, the heat generated in the drum serving to dry the grain.

Abstract: 135,825. Alexanderson, E. F. W. Nov. 26, 1918, [Convention date]. Inductor-alternators; armatures, cooling; coils and conductors.-A high-frequency inductoralternator having a pair of circumferentially laminated core rings 5 carrying the armature winding in slots in opposite faces lying in adjacent planes, is cooled by circulating cooling fluid in pipes located in circumferential slots in the core rings. Pipes for cooling fluid are also located in end rings 4, which, together with clamping- rings 6, 7 support the core-rings 5. The ends of the rings 6, 7 facing the rotor 8 are formed with teeth registering with the teeth in the core-rings 5. The armature winding is wound zigzag in the slots and is held securely in position by passing it round the overhanging parts of the teeth on the rings 6, 7. The armature winding is divided into a number of separate circuits and the terminals of each circuit are formed as heavy copper blocks so as rapidly to conduct away the heat in the part of the armature winding outside the armature slots. The terminals are mounted on the rings 6 and are each provided with a slot to receive the armature conductor. Each section of the armature winding is made up of two layers which are transposed at the middle of the section so that the inner conductor in the slots of any one-half circuit becomes the outer conductor in the slots of the other half of the same circuit. The cooling system is divided into two parts as shown in Fig. 4, one for each half of the machine. The machine is excited by a circumferential coil 10. In addition, two exciting windings 13 may be provided, each of which is made up of semicircular coils.
