[Class 102 (i)] A diaphragm pump is operated by an electromagnet 2, which is energized by alternating current, the reciprocating parts being tuned to the frequency of the current. The magnet effects the suction stroke of the pump so that back pressure in the system forces the armature 3 towards the magnet and closes the magnetic circuit. The armature operates pump diaphragm 5 by means of a rod 4, which is held in a balanced position by springs 8, 9 abutting on an adjustable bar 10. The pump has rubber suction and discharge flap valves 15, 16. In order to equalize the flow the upper walls of the suction chamber 17 and of the discharge chamber 18 are formed by diaphragms 21, 22, which are either resilient or are acted on by springs.

Title: Regenerating coke oven

Abstract: 371,543. Coke ovens. E V E N C E COPPEE & CO., 103, Boulevard de Waterloo, Brussels. March 11, 1931, No. 7496. Convention date, Feb. 2. [Class 51 (ii).] Relates to vertically-flued coke ovens having in the same heating wall uptake and downtake flues connected directly to transverse regenerators numbering at the maximum two per coking chamber, and comprises such an arrangement of the connections that the flues on both sides of alternate ovens are connected to the same pairs of regenerators, and the outflow regenerators are both on the one side of the inflow regenerator. By this arrangement an air regenerator can always be interposed between gas and waste gas regenerators. As shown, the heating system for the battery is divided into a number of independent units each comprising two heating walls on opposite sides of alternate ovens 2, and four regenerators 4, 5, 41, 51, each of which is connected to both of the associated walls through a bifurcated flue, such as the flues 6a leading from the regenerators 4. Assuming that lean gas and air are being heated in the regenerators 4, 5 re spectively, combustion is effected in the corresponding upcast flues in both heating walls, and the products are exhausted through the regenerators 4<1>, 5<1> connected to the downcast flues. In the oven described pairs of upcast and downcast flues alternate along the length of the heating wall. The Specification as open to inspection under Sect. 91 (3) (a) describes also a battery in which there are four quarter-wall groups of flues in each heating wall these groups being connected by a top flue to form two half-wall heating systems. As shown diagrammatically in Fig. 12 (Cancelled), each regenerator is connected to an outside group of flues in one heating wall, and to an inside group of flues in the next heating wall but one, so that groups of four inflow and outflow regenerators alternate along the length of the battery. Gas is heated in the two middle regenerators 4, or 4<1> of a group, and air in the outer ones 5, or 51. This subjectmatter does not appear in the Specification as accepted.
