Title: Improvements in or relating to torque absorption devices
Inventor: CLINE EDWIN LEE
IPC: G01L3/20
Filed: 1951-02-14
Abstract: 711,539. Dynamometers. CLAYTON MANUFACTURING CO. Feb. 14, 1951, No. 3583/51. Class 106 (2). [Also in Group XXXIV] In a torque absorption dynamometer in which a rotor and its housing co-operate to form a working circuit for a power absorbing fluid, heat exchange means are arranged in the housing and/or the rotor to cool the power absorption fluid, said heat exchange means comprising a series of separate hollow heat transfer elements having opposite edge portions connected to header wall portions and arranged to have coolant fluid flow in contact with one surface thereof and said power absorption fluid to flow in contact with another surface thereof. In Fig. 1 the heat exchange means comprises a number of tubes 42 extending between spaced header walls 43 and 44, the walls 43 and 44 co-operating with the outer circumference of the dynamometer 20 to form a chamber 45 for a cooling liquid flowing over the exterior surfaces of the tubes 42. A portion of the power absorbing fluid circulating from the rotor 51 through the normal working circuit of the dynamometer passes through these cooling tubes 42. In Fig. 3 the heat exchanger 104 is arranged around the right hand wall of the dynamometer 75, instead of its circumference, to reduce its diameter. The heat exchanger includes a plurality of removable core elements 110, one of which is shown in cross-section on an enlarged scale in Fig. 4, and through which cooling water flows. A portion of the power absorbing fluid circulating between the rotor 99 and the co-operating section 82 of the stator flows over the outer surface of the cores 110 as indicated by the arrows. In Fig. 10 the heat exchange means comprises a number of cooling tubes 179 extending circumferentially around the stator 172 so as to be in the main working circuit of the power absorbing fluid, the power absorbing fluid flowing over the outer surfaces of the tubes 179 and the cooling fluid through the tubes 179. The dynamometer illustrated in Fig. 15 embodies a combination of the heat exchange means described with reference to Figs. 1 and 10 in that cooling tubes 215 are arranged in the main working circuit of the power absorbing fluid whilst a portion of the power absorbing fluid from the normal working circuit is caused to flow through water cooled tubes 226 arranged outside the normal circuit of the power absorbing fluid. In Fig. 16, a fan 291 on the dynamometer shaft 266 forces cooling air through some tubes 262 extending across the housing 256. The rotor 273 causes a portion of the power absorbing fluid circulating around the normal working circuit to pass over the tubes 262.

Abstract: Packaging material as thin sheets and consisting at least partly of an organic material e.g. synthetic plastic or paper/plastic lamination is sterilised (prior to forming the package) on the side which is to form the inside of the package by heating that side to sterilising temperature whilst the other side of the material is simultaneously cooled by contact with a heat absorbing medium.  The heat may derive from a radiant heater or may be applied by means of a heat carrier e.g. a gas or vapour which may be blown on to the surface.  The cooling medium may be a solid cooled surface which may form a guide surface for a web of the material or it may be a liquid, gas or vapour which is blown or sprayed onto the surface to be cooled.  The specific examples relate to apparatus in which a moving flexible web of the material is, (a) heated by a gas or vapour and cooled by a cooled metallic guiding surface, (b) is heated by an electrical radiant heated (see Group XI) and cooled by a cooled surface of a rotatably mounted drum, and, (c) is heated by a radiant heater and cooled by a gaseous or liquid spray.
