Title: Air-cooled condensers for distillation columns
IPC: B01D5/00
Filed: 1964-08-14
Abstract: 1,075,475. Air-cooled condensers for distillation columns. F. HERMANN and K. WARTENBERG. Aug. 14, 1964 [Sept. 19, 1963], No. 33297/64. Heading B1B. An air-cooled condenser for a distillation column comprises substantially vertical vapourlanes which are laterally defined by hollow heatexchange elements 5 the lower ends of which are open to the atmosphere and the upper ends open into dome 20 so that air is drawn up through the finned-interior of the elements by fan 24. The vapour from the head of the column is conducted through two short pipes 1 (only one is shown) into vessel 3 and is then distributed into the vapour-lanes. The condensate flows down to collection trays 6 below which is a condensate-cooling zone comprising the lower sections of the exchange elements. Trays 6 consist of sectional strips inserted into the lanes. The cascaded trays 7 cause the condensate to flow in a zig-zag course through the cooling zone. The condensate can flow into receiver 14 through two routes. If valves 12 are closed, condensate will be dammed-up in the lower part of vessel 3 and hot condensate will flow over walls 8 into the receiver 14; but if valves 12 are fully open, all the condensate will flow through the cooling zone and then through pipe 11 into the receiver. Any intermediate position of valves 12 will determine the ratio of hot condensate to cool condensate flowing to the receiver; and the two streams mix on baffle system 13 before reaching the receiver. The temperature of the condensate in the receiver is sensed by a suitable element (not shown) associated with a relay which automatically adjusts valves 12. Part of the condensate is withdrawn from the system through pipe 16, and the remainder refluxes to the column through pipe 17. Inert gases in vessel 3 rise over trays 18, and are withdrawn through pipe 19'.

Title: Polyurethane products and method of preparing same
IPC: C08J9/36
Filed: 1961-09-19
Abstract: A method of making a permanently compressed polyurethane product comprises: compressing a foamed cellular polyurethane plastic produced by reacting an organic polyisocyanate with an organic polyether compound containing a plurality of active hydrogen groups reactive with an NCO group; simultaneously subjecting the compressed plastic to an acid for a time sufficient to cause the plastic to retain at least part of its compressed condition; and removing first excess acid and then the compressive force. In examples portions of polyether polyurethane foam are compressed to one-third of their original thickness and treated variously with HCl, H2SO4, HNO3, H3PO4, Cl3CCOOH and CF3COOH at different dilutions and temperatures. After washing with water and removing the compressive force the degree of compression is determined and results are tabulated.

Title: Improvements in bimetallic actuators
IPC: G01K9/00
Filed: 1946-11-11
Abstract: 619,910. Temperature-responsive actuating-elements. WILSON CO., H. A. Nov. 11, 1946, No. 33499. Convention date, April 12, 1940. [Class 64(ii)] [Also in Group XVIII] An actuating device, e.g. for an oscillating advertising device or timing means or for periodically opening and closing electrical contacts, comprises a bowed strip 10 of bimetal and a heat - conducting element 12, upon which the strip rests engaging the strip in heat-conducting relation intermediate the ends of the strip for causing a temperature difference between the part 16 of the strip engaging the element and the portions of the strip not engaging the element, with resultant rocking of the strip on the element. In the application shown, a display card 13 is secured to a cross member 11 holding the bimetal strip 10 in the form of a semicircle and the heat-conducting element 12 is arranged as a flat support which may be either heated or cooled and on which therefore the device rocks. By suitable arrangement of the metals of the strip a flattening instead of a bowing effect may be obtained and this may be used for braking on devices which are rocked by external means e.g. by electromagnets. The Specification as open to inspection under Sect. 91 also describes with respect to cancelled Fig. 7 (not shown) a modification, in which no rocking occurs, as applied to a rate of change thermostat, in which a sudden rise of temperature causes bowing of the bimetal strip at the point of contact with the heat-conducting support, while a slow rise of temperature heats the strip uniformly and therefore causes no bowing, so that in the former case the vertical movement of the cross member opens or closes an electrical contact. This subject matter does not appear in the Specification as accepted.

Class 79(5) [Also in Groups XXIV and XXIX] In a variable ratio steering mechanism employing an eccentric or cam-shaped toothed pinion 15, Fig. 1, on the steering wheel shaft 14 meshing with a corresponddngly shaped rack 17 or with a straight rack suitably supported or guided for actuating the dirigible wheels through tierods coupled to ball studs 24, 25, power operation is provided by the admission of hydraulic pressure fluid to chambers 28, 29 on either side of a fixed pinion 26 in a cylinder 21 secured to the track 17. The hydraulic fluid is supplied to the chambers 28, 29 through a tubular supporting rod 18 and a conduit 31 respectively from ports 32, 33 in the gear housing 12 under control of a valve mechanism 16, Fig. 4. This valve comprises a piston member 53 with a central land 54 controlling the exhaust from chambers 28, 29 through conduits 61, 62. The member 53 is centralized in a neutral position by a spring 85 to relieve both chambers 28, 29 but an axial movement one way or the other by a rod 51 the exhaust of one chamber is closed and one of balanced poppet valves 67 at the ends of the cylinder is actuated to supply pressure fluid through an inlet 69 to that chamber to provide power actuation of the steering. Control and followup of the power drive is effected through a coupling 40 (see also Fig. 5) between the steering wheel section 14a of the shaft 14 and the power section, comprising rollers 42 on shaft section 14a operating in inclined slots 43 in a drum 44 on the other section. Initial rotation of the steering wheel causes the rollers 42 to ride up the inclines 43 to effect an axial movement of shaft section 14a and control rod 51 coupled thereto. The control piston 53 is thus actuated to effect power operation and follow-up is effected through rack and pinion 17, 15 to centralize rollers 42 in slots 43 again and thereby centralize piston 53. During power operation "feel" is provided by the hydraulic pressure acting on the end faces 66, 76 of the piston 53 through restricted orifices 70, 80 but this "feel" is limited by relief valves 72, 83 to reduce the force necessary on the steering wheel under conditions such as during parking operations.
