Title: Improvements in air cooled absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1928-11-15
Abstract: 327,189. Electrolux, Ltd., (Assignees of Lenning, A.). Nov. 15, 1927. [Convention date]. Divided on 300,589. Refrigerating, absorption machines for. -A rectifier and condenser for air cooled machines comprises inclined externally gilled tubes 43, 54, the upper one serving mainly as rectifier, while the higher part of the lower tube becomes effective only for condensing abnormal quantities of refrigerant vapour. The mixed vapours of refrigerant and absorption liquid from the generator. (not shown) rise through a pipe 42 and are cooled preliminarily in the part 45 of the upper tube, and then pass through an open-ended inner tube 49 to the part 46 of the upper tube. Refrigerant is condensed outside the tube 49 and is partly revaporized in cooling solvent vapour within this tube. The solvent flows back to the generator through notches or apertures in discs 48 in the tube, while the refrigerant liquid and vapour flow through a central pipe 53 to the lower condenser element, from which condensate passes away through a pipe 61 to the evaporator. In inert gas systems, any inert gasentrained to the generator side collects in the lower tube 54, and the liquid refrigerant flows, to the outlet 61 in the presence of this gas. A vent pipe 60 leads surplus gas back tc the evaporator-absorber side.

Abstract: 379,210. Lubricating stuffing-boxes. SMITH, R. J., FOSTER, F. H., and HASLAM & NEWTON, Ltd., Union Foundry, Derby. Jan. 16, 1932, No. 1366. [Class 12 (ii).] The casing of a stuffing-box substitute is provided with two non-rotary rings which have faces resiliently engaging two rings rotating with the shaft. Faces on the rotary rings eccentric to the shaft engage faces on the non- rotary rings concentric with the shaft so that lubricant supplied to the casing is maintained upon the rubbing surfaces. In the construction shown in Fig. 1, the ring c is prevented from rotating by a stud f and the ring d is clamped between the casing e and its cover. The rings m, n have eccentric rubbing faces, Fig. 2, the opposite sides of which are chamfered off, and are provided with boxes containing packing r, s, which is engaged by glands o, p under the action of a spring q. Lubricant is supplied through a passage t in the shaft. In a modification, one of the non-rotary rings is carried by a diaphragm, and the other non-rotary ring is held up to the co-acting rotary ring on the shaft by a spring-pressed gland engaging packing in a recess therein. The oil is contained in an exterior reservoir to which it is supplied through a filler and from which it passes into the space between the packing-rings.

Abstract: 157,739. Farr, F. G. Jan. 19, 1918, [Convention date]. Direct liquid-pressure apparatus. - In systems wherein the oil is stored over a displacement liquid, such as water, the lower limit of oil level is indicated, and overfilling and escape of oil into the drain are prevented, by means of a pipe H, Fig. 1, having its lower end located at the lowest permissible oil level in the tank A and its upper end at a level between that of the water displacement connection or drain C and the corresponding level of a balancing column of oil, so that when the oil reaches the lower end of the pipe H, it displaces the water therein, and oil escapes at the upper end. A valve I in the pipe H is adapted to be opened and closed simultaneously with a valve J in the oil-filling pipe G. In the modification shown in Fig. 2, the valve I is so connected with the water-control valve E as to be opened when the water pipe B is connected to the drain C and closed when the pipe B is connected to the pressure head D. The Specification as open to inspection under Sect. 91 (3) (a) states that in a further construction, the upper end of the pipe H is connected to a chamber containing a float, which is lifted by a rise of oil to close a valve in the oil-inlet pipe or water-discharge pipe, or in both. This subject-matter does not appear in the Specification as accepted.
