Title: Electrical circuit for temp. measurement - has temp. sensitive and fixed resistors connected in series and difference between voltage drops measured
Inventor: HAUSSMANN GUENTER DIPL ING
IPC: G01K7/20
Filed: 1976-08-11
Abstract: The circuit comprises a first resistor whose resistance is affected by temperature. Voltage drop across this resistor, produced by a specified current (I) is measured, and the current (I) is measured by the voltage drop it produces across a second, fixed resistor in series with the first. Voltage drop across the first resistor (RT) is measured by connection in opposition to the voltage drop across the second resistor (RO) and the difference between the two voltages is then measured. The circuit arrangement may be used in a similar way to determine other physical values which may be evaluated in terms of an electrical resistance factor.

Title: Paired cylinder two stage combustion IC engine - has valve connecting cylinders for second stage lean fuel, rich oxygen combustion
Inventor: HURD FRASER ATKINSON
IPC: F02B41/06
Filed: 1976-10-20
Abstract: An internal combustion engine has one or more compounded pairs of undulating volumes, such as produced by a piston reciprocating within a cylinder which share periodically common combustion and which are provided with combustible fuel mixtures prepared externally. The fuel-air mixture, when involving a petroleum type fuel, is burned internally in two stages, the first burn at elevated temperatures is a fuel-rich, oxygen-lean mixture to minimize the nitrous oxides produced, and the second burn at lower temperatures is a fuel-lean, oxygen-rich mixture to substantially complete combustion of unburned hydrocarbons and oxidize carbon monoxide prior to being exhausted to the atmosphere. Paired cylinders communicate to form a common combustion chamber to effect the second stage burn and extended power expansion by differential displacement. Both cylinders have inlet valves, only the second stage having an exhaust, a movable valve allowing communication between the cylinders.

Title: Polymer gear pump - with gear chamber and sealed zone shaped for optimum efficiency
Inventor: MOKED ISAAC
IPC: B29C48/92
Filed: 1977-04-15
Abstract: A gear pump for the transport of highly viscous materials includes two meshing gear wheels in a casing in which adequate free space is left for the material. A sealed zone near the outlet has a minimum length on both sides of the distance between adjacent teeth across the full axial width. The outlet itself has a cross-sectional area of 0.2 to 2-times the product of gear wheel width and tooth height. In plants for the production of polymers and volatile components, such as low-density polyethylene and ethylene also in mixing and compound installations. The free space around the gear wheels results in an interaction of the pumped material which is caused by the revolving gear wheels and the pump casing above the sealed zone and produces a pressure above the pump intake pressure. The shear surfaces and the power losses caused by shear are on eorder of magnitude lower than with conventional positive displacement pumps. A gear pump is less costly and causes less temp. rise than a screw extruder.
