Abstract: ABSTRACT OF THE DISCLOSURE    Multiple layer films and containers.   The films have a first layer of either nylon 6,6 or a combination of nylon 6,6 with moieties of a second nylon polymer wherein the melting point temperature of the combination is greater than the melting point temperature of the corresponding second nylon polymer.  A second heat sealable layer  comprises a polymeric composition having a melting point temperature between about 110°C. and at least 10°C. less then the melting point temperature of the first layer.  A third adhesive layer can be disposed between the first and second layers.  The containers are susceptible of being sealed with included gas at low pressure,  and subsequently boiled in water without rupture of the seals.  The film is preferably coextruded from tubular die, thereby setting forth a new method  for  forming a multiple  layer  film comprising a combination of a first layer having a first composition of nylon 6,6, optionally combined with moieties of a second nylon polymer in a composition having a melting point temperature greater than that of the corresponding second nylon polymer, and a second layer having a second polymeric composition.

Abstract: The prefabricated creep foundation in accordance with the invention is a building system for the laying of the foundations for a heated building with a beam structure above an enclosed, unventilated creep space. The foundations are constructed from base plates made of concrete, foundation beams made of concrete with internal cellular plastic, and ventilation grids for ventilation. The foundation beams consist of an externally reinforced high concrete slab with thick, cast-on-cellular plastic insulation on the inside. The creep space can be inspected more easily thanks to the considerable height of the foundation beams. The thick cellular plastic insulation on the foundation beams enables surplus heat to be utilized, so that the laying of the foundations can take place at a reduced foundation depth. The foundations can be laid using a crane, and can be adapted to the requirements of the project. The invention also relates to a method and means for the production of elements from which the foundations can be constructed.

Title: Apparatus for controlling the torque of an engine pump system, and a method thereof

Granted: 1997-10-07
Abstract: A torque control system for variable delivery pumps receiving torque from an engine employs a signal related to an engine torque available at each engine speed setting to control the torque, and thus the amount of engine power that is absorbed by the variable delivery pumps.  In a low-power regime, wherein the fuel injected into the engine is  less  than maximum,  torque control  is  effected by comparing the available torque with an amount of torque that would be available at maximum fuel injection.   In a high-power regime,  wherein the fuel injected is at least a predetermined value, torque control is effected by comparing the available torque with an amount of torque that is available at a combination of a set engine speed and an actual engine speed.  A bias circuit biases the stable speed operating  point a small amount below the maximum speed, whereby improved fuel economy is attained.  In a system with more than one variable delivery pump, when less than the full number of pumps is employed, control is effected in the low-power regime,  even though all pumps in service are receiving maximum fuel.
