Abstract: 968,081. Dynamo-electric machines. L. R. POWER CORPORATION. Sept. 9, 1960 [Sept. 9, 1959], No. 31169/60. Heading H2A. A field producing structure for a dynamoelectric machine of the axial air gap type, comprises an annular body of ceramic magnet material, an annular casing of unitary construction having a generally concentric wall peripherally encircling said body and protecting it against centrifugal forces and a retainer means fixed to the casing and locking the body in place. In one embodiment thereof, Fig. 2, the ceramic magnet 6 is held in a cup-shaped aluminium casing 2, by a retaining ring 9, which casing is fixed on to shaft 1 by pin 8. A flux return plate 7 is interposed between the end wall 5 of the casing 2 and the rear face of the magnet 6. In a further embodiment, the return plate 7 may have a rim which interposes between the magnet and wall 4 of casing 2, Fig. 3 (not shown). In another embodiment, Fig. 4, the casing 2 may be replaced by the flux return plate 7<SP>1</SP>, which is made of a shape suitable to support the magnet which is held in place by outer rings 2<SP>1</SP>. The retaining ring 9 may still be used, Fig. 5 (not shown). Fig. 6 shows a modification of Fig. 2, in which a highly conductive casing 20 replaces the retaining ring 9, and outer wall 4. Wall 12 protects the working surface of the magnet from spalling and demagnetization. The two sections of the casing, 20 and 5, are held together by nut 16 and shoulder 14, and may also be screwed together. In another modification, Figs. 7 and 8, giving protection to the face of the magnet, the magnet is recessed to define the poles and the casing 12 is shaped to surround the poles in the recesses. In another embodiment, Figs. 9 and 10, the airgap face of the magnet may be shaped to define pole faces 6<SP>1</SP>, and the spaces in between the faces may be filled with a temperature compensating material 17, for example a nickel-steel alloy, the permeability of which decreases with rise of temperature and compensates for the fall in strength of the magnet, to produce a substantially constant inter-pole flux. The material 17 may extend over the pole faces. A method of strengthening the ceramic magnet is described, involving impregnating the magnet with epoxy resin after it has been placed in a vacuum, and then curing the magnet by catalyzed polymerization.

Title: Improved means for counting printed sheets issuing from rotary printing machines
IPC: G06M7/06
Filed: 1926-12-10
Abstract: 284,822. Holmes, W. Dec. 10, 1926. Counting -apparatus.-Apparatus for counting sheets such as newspapers issuing from rotary printing machines is controlled by a device serving, when the sheets are being delivered in the normal way, to effect the closing of an electric circuit which is utilised to connect the counter to a moving part of the machine, but disconnects the counter from the machine when the machine is not working normally. In one arrangement, an electrically-operated counter 3, Fig. 4, is connected in series with a battery 2, a make-and-break device 1, and a switch 7, the device 1 being operated from a moving part of the machine so that, providing the switch 7 is closed, it closes the circuit and operates the counter once for every sheet or for every predetermined number of sheets delivered. The device 1 consists of a disc rotated from the machine and having insulated conducting segments 1<a> upon which bears a contact brush in the electric circuit. The switch 7 remains closed while the machine is printing normally and may comprise a pivoted finger 9, Fig. 2, pressed by means of an insulated cylinder 10 containing mercury against the endless line of sheets 6 being delivered, so that if the delivery is interrupted, the finger 9 and container 10 tilt over and the mercury becomes disengaged from contacts in the counter-circuit, which is thus broken. Another device for controlling the circuit comprises a centrifugal governor which closes the circuit during normal running, but if the speed is below normal, as for example during the taking of test pulls, the circuit is opened and no operation of the counter takes place. In a modified arrangement, the switch 7 serves to close an electric circuit operating a clutch so as to connect a mechanically-operated counter to a shaft driven by a flexible drive from the printing machine. According to the Provisional Specification, in cases where the papers are delivered in an unbroken line, the passage of the papers between two spring-pressed rollers may be utilised to close the circuit of the connecting clutch. Also the movement of the rollers caused by the passing papers may be utilized to operate the counting- apparatus through mechanical connections.
