Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1942-02-13
Abstract: 548,856. Refrigerating. ELECTROLUX, Ltd. Feb 13. 1942. No. 1929. Convention date, Feb 26, 1941. [Class 29] Absorption systems.-In a continuous-cycle inert gas system having two or more evaporators, refrigerant is distributed to the evaporators according to their individual requirements by regulating the flow to at least one of the evaporators mechanically or thermostatically. In the system shown in Fig. 1 refrigerant flows from the condenser 16 to a reservoir 19 from which an overflow 20 leads to one evaporator 10, connected by pipes 12, 13 to the inert gas circuit. A U-tube 21 connects the reservoir 19 with a vessel 22 from which another evaporator 11 I is supplied. Refrigerant is lifted in the right-hand limb of the U-tube by a heat pump, preferably comprising a closed condensing heat transfer system 25, 26, 27, 28, the evaporator portion 26 of this system being in thermal contact with the generator 17 or with the vapour expulsion pipe. The heat transfer system is controlled by a manual, clockwork or thermal valve 29, so that when this valve is closed no heat transfer circulation takes place and no refrigerant is raised in the U-tube 21 to the vessel 22 and the evaporator 10 alone receives supply. The evaporator element of the heat transfer system may effect rectification of expelled vapours, and the control of supply to the evaporator may be employed for effecting defrosting. In one modification supply to each of two evaporators is effected through separate U-tubes connected to the condensate reservoir. An alternative arrangement comprises a tilting reservoir 40, Fig. 3, connected to a resilient condenser coil 16, and resilent pipes 43, 44 leading to evaporators 45, 46. The pipes 43, 44 extend to different levels in the reservoir, which may be tilted by an arm 41 and cam 42 to alter the distribution of the liquid. As a modification of this form the reservoir may be divided by a mid partition on to either side of which refrigerant is delivered from the condenser.

Abstract: 765,299. Coffee percolators. LANDERS, FRARY & CLARK. Jan. 24, 1955 [March 16, 1954], No. 2084/55. Class 129 [Also in Groups XI and XXXVII] A coffee maker comprises a water vessel 2, a, perforated basket 70 for ground coffee, a fountain tube 58 extending from the bottom of the vessel to a point above the basket, a spout 140 with its inner end below the basket 70 and a tray 96 which is moved from a position where it directs liquid draining from the basket back into the vessel to a position where it directs the liquid to the spout by temperature sensitive means when the vessel is raised to a selected temperature. Vessel 2 may be filled to any level up to the level 5 and has a cover 6 incorporating a glass top 7. A well 42 has a screw threaded top which fits into the bottom 3 of vessel 2 and is held by a clamping ring 46. A heating coil 10 surrounds well 42 and its top is closed by a perforated cover plate 50 which supports tube 58. A ring 62 slides on the lower part of tube 58 so that as the water in well 42 is heated steam holds ring 62 against the perforations in plate 50; eventually the water is forced up tube 58 and over the top until well 42 empties, whereupon steam escapes through tube 58 and further water is drawn in through the perforations. Tray 96 has trunnions 90, which engage V- shaped supports 86, secured to the walls of vessel 2, a central tube to fit loosely over tube 58 and drains 102, 104, the end of the tray adjacent drain 104 being heavier than the other end. The heavier end of the tray is supported by a bimetallic strip 130 which engages the flange 118 of a slide 112, Fig. 4, having a slot 114 within which engages a rivet 116 secured to the tray. Flange 118 has steps 120, 122, 124 and the slide may be moved by control 110 to vary the time of infusion. As the water in vessel 2 is heated, strip 130 bends until eventually it disengages from the flange 118 allowing tray 96 to pivot until its heavy end rests on spout 140. The heating coil 10 is connected in series with a switch comprising contacts 14, 16 carried on flexible contact arms 18, 20, so as to be normally closed. Arm 18 extends beyond contact 14 and carries an insulating lug which may be engaged by bimetallic strip 28, either when it is heated or when it is engaged by a cam 30 on a pivoted arm 32 integral with knob 36, to separate contacts 14, 16. In operation percolation starts when knob 36 is raised to release strip 28 and hence arm 18 and continues, the liquid being returned to the vessel through drain 102, until bimetallic strip 130 releases the tray 96 after which the brew is delivered to the spout. When vessel 2 has emptied the temperature rises rapidly and bimetallic strip 28 bends to separate contacts 14, 16 and de-energize coil 10, meanwhile releasing cam 30 so that knob 36 falls into'its " off " position.
