Title: Improvements in or relating to a calender machine
IPC: D21G1/00
Filed: 1946-10-29
Abstract: 628,880. Calendering paper &c. NEW YORK & PENNSYLVANIA CO., Inc. Oct. 29, 1946, No. 32049. Convention date, Nov. 3, 1945. [Class 96] To avoid difficulties due to distortion of soft-surfaced rolls of a super-calender stack and consequent uneven stretching, a web W of paper &c., e.g. from the drier section of a paper-making machine is super-calendered by passing through a succession of calender presses such as that illustrated, in series. The rolls 18 are of metal, e.g. chilled iron, and are driven individually to accommodate stretching of the web. The rolls 44 have compressed fibre or paper coverings, a pair of rolls 44 being mounted diammetrically of each pressure roll 29 and driven thereby at the speed of travel of the web W. They are so mounted that the upper and lower rolls 44 of each pair can be interchanged by starting an electric motor which turns chain gearing and a ring gear 46, thus enabling the lower roll 44, if damaged, to be swung round, substituted by the upper roll 44, and taken out, with the machine running, split bearing clamps 31 facilitating replacement of the rolls 44. The bearings of the pressure roll 29 are on arms 26 pivoted to a carriage 22 adjusted vertically at 24 &c., the ends of the arms being connected by lostmotion links 63 and springs 62 with arms 59 raised and lowered by motor and worm gear above a screw-rod 60 to raise and to control the spring pressure on the rolls 29. Doctors 57 and 21 are fitted, and the web may be moistened by jets of water or steam before passing into the nips of the super-calender. A guide roll 65 may be cooled or steam-heated.

Patent GB-894278-A (GB)
Title: Improvements in or relating to absorption refrigerating systems
IPC: F25B47/02
Filed: 1960-09-26
Abstract: 894,278. Refrigerators. WHIRLPOOL CORPORATION. Sept. 26, 1960 [Nov. 13, 1959], No. 33050/60. Class 29 An absorption refrigeration system includes an evaporator 10, 11 in which the liquid refrigerant is normally evaporated to produce refrigeration and defrosting apparatus comprising a conduit 29 leading to the evaporator from a reservoir 28 for liquid refrigerant means 31 being provided for heating refrigerant in the reservoir, means being provided for expelling heated refrigerant in the form of both liquid and gas through the conduit into the evaporator 10, 11 for defrosting the same, and means in the evaporator operated by the liquid refrigerant for reducing the normal evaporation of refrigerant in the evaporator when heated refrigerant is expelled into the evaporator. In normal refrigerating operation of the apparatus an inert gas, hydrogen, flows upwardly through a pipe 15 and empties by way of an extension 18 into the upper end 30 of the evaporator 10. Liquid refrigerant passes through a pipe 20 and is precooled by a heat exchanger 12 before entering the evaporator 10. Some of this liquid refrigerant evaporates into the inert atmosphere in the evaporator 10 while the remainder flows down the evaporator 10 and via a pipe 21 into a second evaporator 11 where some of it evaporates into the gaseous refrigerant which has flown from the evaporator 10 via a tube 13 to the evaporator 11. The remaining liquid refrigerant flows down the evaporator 11 and through a pipe 22, accumulator chamber 23 and pipe 32 into the upper end of the heat exchanger 12 where it evaporates into the atmosphere of inert gas and refrigerant gas. The resulting relatively rich gas then flows through tube 16 to the absorber. Liquid refrigerant from the chamber 23 flows through a pipe 25 into the reservoir loop 27, 28, 29. To defrost the evaporator an electric heater 31 is energized either manually or by a timer and the heat generated vaporizes some of the liquid refrigerant in the pipe 29. This causes a hot mixture of liquid refrigerant and gaseous refrigerant to be lifted up the pipe 29 into the evaporator 10. The hot liquid refrigerant first fills a dish 34 (Fig. 2) and then flows down through the evaporators 10, 11 to defrost them. The filling of the dish 34 blocks the end 19 of the inert gas pipe extension to reduce substantially the flow of inert gas. A limited gas flow continues through an opening 37. A gas of high ammonia concentration will result and as the dew point of the gas is well above 32‹ F. ammonia condensing out of the gas will defrost the evaporators. At the end of the defrost cycle, the electric heater is de-energized, the gas-lift pumping action in the tube 29 stops and liquid in the dish 34 drains off through an opening 35 to break the liquid seal at the end 19 of the pipe 15 and permits the normal flow of inert gas. In a modification the outlet from the accumulator chamber leading to the evaporator system leads from the chamber at a point beneath the level of the outlet leading to the reservoir.

Apparatus for cleaning industrial gases containing suspended matter or cooling industrial gases or both comprises a container 10 containing a body of liquid on to the surface of which the gas to be treated is directed at high velocity through a vertical conduit 17 having an adjustable cone-shaped throttle 20 so that any suspended matter in the gases is driven into and is retained by the body of liquid, the floor of the container 10 sloping so that the liquid is deeper towards that end of the container adjacent the gas inlet 17. Liquid is supplied by a pipe 5 and overflows over an adjustable weir 22 and out through a pipe 23, the space above the pipe 23 having a vent pipe 60 leading back to the gas space of the container 10 as shown. The gas passes over the upper end of a baffle 6 and underneath a second baffle 8 to remove entrained liquid and leaves by an outlet 16. A fan 61 may be provided to induce the flow of gas. The baffle 6 is perforated at 7 and the baffle 8 has an inverted V-shaped member 8a which deflects liquid running down the baffle towards the outer edges of the baffle. In a modification, Fig. 4, a packed tower 13 is used for removing entrained liquid and the liquid sprays 15 supply liquid to the container 10. The liquid overflow may be arranged to pass through a series of containers 30, 30a and 30b where it is contacted with a stream of stripping air supplied through pipe 36b to remove from the liquid physically absorbed gaseous impurities such as, for example, sulphur di-oxide. The gas entering the apparatus for treatment may, if necessary, have been subjected to a pretreatment, for example by spraying with water, injecting steam or ionization in an electrostatic ionizer. Specification 713,985 is referred to.
