Abstract: MECHANICALLY PLATED COATINGS CONTAINING LUBRICANT PARTICLES                  ABSTRACT OF THE DISCLOSURE     In  a  mechanical plating process, lubricant particles can  be  coated  on  a  metal  substrate together with the particulate  plating  metal  to  enhance the mechanically-applied   coating's  lubricity.    The  lubricant  can  be particles    of   fluorocarbon polymers,   fluorocarbon-hydrocarbon   blended   polymers,   powdered,    elemental carbon,   powdered   fluorinated   carbon,   or   mixtures thereof.    The  lubricant  particles have a diameter less than  the  thickness of the coating (which is usually from 2.5  to  132.5  mils),  so they will not be dislodged from the  coating.  The particles must not be too small or they may  be  washed  away by plating liquids or may be applied too  far  from  the  coating surface to enhance lubricity. These  dimensional relationships insure that the lubricant particles are entrapped within the coating.

Abstract: Heat exchanger intended to be flown through by two media and for heat exchange via heat exchanging surfaces in such a way, that the media do not directly contact each other, where the heating surfaces are located rotation symmetrical in relation to, for example, an axis, and the main flow direction of the media is in parallel with said axis. The object is to reduce the overall height and material consumption while maintaining the size of the heat exchanging surfaces. When the heat exchanger is used as an evaporator, the overall height additionally is reduced in that the expansion chamber, which normally is located above the heat exchanger unit, can be positioned centrally within the evaporator (heat exchanger). The said improvement is achieved in that the heating surfaces D are located in an annular area about said axis, so that a central hollow space without heat exchanging surfaces is formed about the central axis.

Inventor: ZEHNDER JUERG
IPC: B61D17/18
Filed: 1980-12-16
Abstract: With known vehicle superstructures of the above kind it has been found that in many cases relatively large amounts of deformation and damage to parts of the floor and walls occur even when the collision is very slight, that the thermal insulation is inadequate and that noises are produced in the sidewalls and floor due to vibrations during the journey. With the new vehicle superstructure the external forces acting on the sidewalls are no longer transmitted directly to the floor but reduced to a minimum level, which in most cases does not damage the floor, by means of a close-fit connection with built-in buffer zone. Also, the new design improves thermal insulation and markedly reduces the noises produced in the superstructure during a journey. Furthermore, the parts which have to be repaired can be readily removed and replaced.

Abstract: A machine for feeding beverage cans to open-ended carrier sleeves of varying capacities. When loading relatively small carrier sleeves, inboard conveyors and associated metering screws feed groups of cans to a flight bar conveyor which moves the groups through the open ends of the carrier sleeves. When loading relatively large carrier sleeves, outboard conveyors and associated metering screws are also operated after first replacing the inboard screws with screws able to separate cans into larger groups, the same size as those formed by the outboard screws. This arrangement feeds larger groups of cans which are then fed to the larger carrier sleeves. In one embodiment each conveyor comprises a longer upstream conveyor and a shorter downstream conveyor spaced a short distance therefrom to allow the flight bars to travel through the space between the conveyors when moving from the end of their upward run to the beginning of their horizontal downstream run. In another embodiment only the longer upstream conveyor is provided and a support plate is used instead of the downstream conveyor. In this embodiment the gap between the conveyor and the plate is automatically closed by a shuttle mechanism to provide a continuous support surface for the cans as they are pushed toward the carrier sleeves. The cans are able to slide on the surface of the conveyors, enabling the conveyors to be operated at a slightly greater speed than the screws are capable of moving the cans, which results in the cans being positively fed by the conveyors.

Water is added to the chips prior to feeding the chips between the discs (5). Moisture content of the thermomechanical pulp is measured after the thermomechanical pulp refiner at least in a semicontinuous fashion by at least one measurement device (21, 22, 23, 24) operating on-line, and on the basis of measured moisture content, the quantity of chips and water to be metered is controlled so as to regulate the moisture content to a desired level of having a constant value by, e.g., increasing the volume of metered chips and simultaneously decreasing the quantity of fed water for an increasing trend of moisture content, and correspondingly, applying an opposite strategy to counter a decreasing trend of moisture content. The implementation provides for a consistent quality of thermomechanical pulp.

Abstract: The present invention relates to a method for producing, by means of working, mixing and homogenizing, castable explosive substances of high viscosity containing crystalline and/or particulate explosives and, if appropriate, other action-enhancing additives and such small quantities of binder and other viscosity-reducing agents that the mixture in the unworked state virtually feels like and behaves like a dry powder. In order to achieve the desired working, mixing and homogenizing, the components are brought to the roll nip between two helically grooved rolls, which form part of a so-called mixing, sheaving and rolling mill. The rolls are arranged at an adjustable distance from each other and counter-rotating at different speeds. The mixture is worked on and between the rolls until the air between the particles included has been pressed out sufficiently to convert the previously pulverulent mixture to a coherent mass of high viscosity. The material is removed from the fastest rotating roll in continuous form or in a newly formed particulate form associated therewith.
