Abstract: 650,364. Refrigerating. ELECTROLUX, Ltd. Nov. 4, 1948, No. 28647. Convention date, Nov. 18, 1947. [Class 29] The shelf-like evaporator of an absorption refrigerating apparatus comprises a goods-supporting plate 20 extending, for example, over the entire cross section of the cooling chamber and having a flat pipe coil 10 secured to its under face by attachment members 25, spot welds &c. and a second horizontal coil 11 connected to the upper face of a second plate 28, the plates being assembled with the coils between them and coated with a metal binding agent providing a thermal connection between the coils and plates and forming a corrosion protective coating. As shown, the coil 10 forming a low-temperature evaporator is secured by clamps 25 spot-welded to the underside of the plate 20 and is joined by a; pipe 13 to a high-temperature evaporator coil 11 secured by clamps 26 to the upper side of a plate 28. The upper plate has side flanges 23, and after the coils have been attached the plates are secured together by welding at 29, 30 to form a housing for the coils. The connecting pipe 13 is then welded at 31, the gas heat exchanger 15 and condensate pipe 12 attached, and the evaporator hot galvanized, the zinc penetrating the spaces between the plates and the coils. Excess molten zinc flows away through openings 40. The top plate 20 has recesses 21, 22 of different depths for ice trays, so that one part of the coil 10 is higher than the other to aid gas circulation. Drain pipes 37 discharge melt water to drip trays. Cooling fins 27 are attached to the lower face of the lower plate 28 which has embossed drain channels 39 leading to a drain opening 38. Wire coils are inserted in the pipes and aid evaporation. Refrigerant is supplied by the pipe 12 and weak gas by a pipe. 14 to the low temperature coil 10, rich gas leaving through a conduit 17 and the gas heat exchanger 15. Pipes 18, 19 connect the refrigerant supply pipe 12 with the rich gas passage of the gas heat exchanger so that part of the rich gas passes through the pipe 12 to cool the condensate. A liquid seal in the pipe 12 prevents weak gas entering the rich gas passage of the heat exchanger through the pipes 12, 18, 19. Reference has been directed by the Comptroller to Specification 639,848.

Title: Fluid control circuit for regulating communication between a source of fluid under pressure and a hydraulic motor
IPC: F15B11/05
Filed: 1975-07-11
Abstract: 1514985 Fluid-pressure servomotor systems CATERPILLAR TRACTOR CO 11 July 1975 [15 July 1974] 29304/75 Heading G3P [Also in Divisions E1, F1 and F2] A valve 22 having a landed spool 28 controlling flow from an inlet chamber 23 to one or other work chamber 62, 63 connected to hydraulic motor 13, e.g. of bulldozer blade 16, has an associated inlet pressure relief valve 31 with a ported piston 47 defining a chamber 49 subject to pressure in inlet chamber 23 and an opposing chamber 51 containing biasing spring 32 and subject via a signal line to the pressure in work chamber 62 or 63 prior to communication of the latter with inlet chamber 23. Spool 28 is provided with axially extending signal slots 92, 93 which in the neutral position, shown, communicate the pressure in drain chambers 71, 72 to fixed orifices 96, 98. The latter normally connect via signal lines 94, 97, shuttle 101, and lines 99, 56 with relief valve chamber 51. Thus in the neutral state only a small force resists opening to drain 46 of  valve 31 under the action of fluid from pump 12. Should spool 28 be moved, e.g. rightwards, towards an operative position Fig. 4 (not shown), signal slot 92 moves out of drain chamber 71 into work chamber 62, thus communicating the higher pressure in the latter to relief valve chamber 51 before land slot 83 connects work chamber 62 with inlet chamber 23. The relief pressure of valve 31 consequently increases. Slots 92, 93 are arranged such that the former connects with chamber 62 before the latter passes out of register with orifice 98, thus avoiding hydraulic locking. Valve 22 is associated with a further valve 34 for controlling flow from pump 12 via lines 41, 42 to, e.g., a ripper jack. When valve 34 is moved to an operating position by manual pilot valve 40, the increasing pressure in line 44 urges the spool 102 of a valve 36 upwards against spring 104 thus breaking communication between signal lines 99, 56 but connecting the latter to line 107 subject via orifice 106 to the pressure in chamber 49. Thus during operation of valve 34, relief valve 31 is pilot controlled by valve 36. A valve 57 relieves excessive pressure in relief valve chamber 51. Main spool 28 can be held by detent mechanism 74, 77 in an extreme rightwards position in which inlet chamber 23 and both ends of jack 13 communicate with one of drain chambers 71, 72. Bulldozer blade 16 can thus float along the ground.

Title: Improved process for distilling or cracking oils and like carbonaceous liquids
IPC: C10G9/42
Filed: 1927-11-03
Abstract: 305,263. Rispler, A. L. Nov. 3, 1927. Hydrocarbons, cracking and distilling.-Oils, tars, and like carbonaceous liquids are distilled with the simultaneous separation and reduction to powder of their non-volatile contents, by passing them through a pipe L<1> into a rotary still 3 containing iron balls and like crushing material J and heated in a furnace 4. The temperature of the still is sufficient to cause immediate vaporization of the volatile constituents, the heavy asphaltic portions and the carbon being deflected by a baffle B and dropping on to the crushing members J, where they are reduced to a powder and deprived of any remaining volatile contents. Steam is preferably blown into the still through a pipe L<2> and an annular passage surrounding the pipe L'. The steam aids the distillation and is also used for blowing out the dried powder accumulating in the still, which for this purpose is provided with a conical end 10. The vapours produced are led off to the usual condensers through a pipe 5. Alternatively, the powdered residue may be evacuated by placing a grating over the charging hole H and rotating the still.
