Filed: 1928-04-25
Abstract: 315,496. Carpenter, R. E. H. April 25, 1928. Electromagnets .-An electromagnetic device, more particularly a contact-making relay, loudspeaker driving unit, or gramophone pick-up, comprises a vibratory armature and a magnetic structure consisting of a portion embodying a circuit of low reluctance to carry the fluctuating flux and a portion embodying two parallel paths for the steady polarizing flux and possessing a reluctance substantially larger than that of the portion of low reluctance which includes the effective air gap in which the armature vibrates. Figs 1 and 2 show a construction of a contactmaking relay in which the magnetic structure comprises a horizontal limb 1 connected by permanent magnets 2, 3 to L-shaped limbs 4, 5 which form the part of the low reluctance magnetic circuit through which the steady flux passes. Like poles of the magnets are connected to the limb 1 to the centre of which is secured the central member 6 so that the fluxes from the magnets 2. 3 pass in parallel through the member 6 in the same direction. The armature 7 carrying the tongue 8 is pivoted to the member 6 either by a knife-edged pivot or, as shown, by blade springs 9 clamped in non- magnetic brackets 10. The butts 11, 12 are adjustably mounted in pillars 13, 14 insulated from the limbs 4, 5. The outer ends of the limbs 4, 5, are connected by a bridge piece 20 of smaller cross section which carries the coil 22 and is retained in notches in the limbs by readily removable clamping plates 21. Fig. 5 is a diagram of the magnetic circuit, the low reluctance portion carrying the fluctuating flux comprising the bridge-piece 20. limbs 4, 5 and the effective air gap whilst the portion of substan tially higher reluctance embodying two paths in parallel for the steady, polarizing flux is made up of the limb 1, central member 6, limbs 4, 5 and magnets 2, 3. The reluctance of this latter portion may be increased by the insertion of saturated portions of reduced area or air gaps in the divided branches. In order to correct for any steady-current which may be flowing in the bridge-piece 20, a bar magnet 27, pivoted at 28, to the member 6 is adapted to be turned under the action of a screw 31 and spring 29 so as to assist one or other of the magnets 2, 3. When applied as a driving unit for a loud-speaker, the tongue 8 may be replaced by a reed or the member 6 may be pivoted at its lower end and itself form the reed.

Title: Improvements in or relating to methods of recovering or refining lead and lead alloys
IPC: C22B13/06
Filed: 1931-04-25
Abstract: Lead alloys containing metals such as tin, antimony, and copper, particularly scrap storage battery plates, are refined by heating the material in a furnace, drawing off the comparatively pure melted lead, further heating the remaining material with the addition of reducing agent, and drawing off the resulting lead-antimony alloy which is comparatively high in antimony. Litharge may be added to the initial material, and molten lead and litharge may be drawn off together to further refine the lead; or the scrap may be melted with reducing agent.  The scrap may be so melted as to produce a pool of lead covered with oxide, and the pool may be agitated with the oxide to transfer antimony from the lead to the oxide.

Title: Method and apparatus for controlling the quantity of oil coated on continuously moving material
IPC: C23F15/00
Filed: 1973-03-14
Abstract: 1413413 Photo-electric measurement of oil film thickness NIPPON KOKAN KK 14 March 1973 [21 April 1972] 12343/73 Heading G1A [Also in Division G3] The thickness of an oil film applied to continuously moving material 1, e.g. tinned steel strip, is measured by comparing signals from two polarized projector/receiver combinations 14 arranged respectively before and after the oil application at 17 and the measurement is used to regulate the application and thereby keep the oil thickness constant. Each projector, Fig. 1 (not shown), has a collimator, a silver interference filter to limit the wavelength used, a polarizing screen and a quarter-wavelength plate. Each receiver has a rotatable polarizing screen, lens, diffuser and detector, e.g. a photo-transistor. The output of the receivers is as shown in Fig. 2 which relates output voltage V with the angle # of the polarizing screen, the displacement between curves a and b being due only to the film thickness. In the embodiment shown in Fig. 4 the polarizers in the two receivers are kept in alignment at # f  so that the difference in their outputs is the voltage #V, produced at comparator 16. This is compared with a reference value representing desired thickness and any error is used to regulate the flow of oil to, or the voltage applied to, an electrostatic oiler 17, 18, also Fig. 6 (not shown). In an alternative embodiment, Fig. 5 (not shown), the output of each receiver drives a servomotor which rotates the polarizer until the output equals a reference value VL, Fig. 2, (or alternatively is a minimum). The respective angles are measured e.g. by potentiometers and the difference between them represents #H, and this signal is compared with the reference for control as before.
