Abstract: The antigen etc. is bound by the formation of a complex to a specific enzyme-labelled anti antibodies in soln. Smaller microorganisms or cells are bound to inert particles. The soln. is then named through a filter which retains the complex bound particles and microorganisms or cells but allows through the unbound specific enzyme labelled anti antibodies. The filtered soln. is brought into contact with a specific substrate which breaks down the enzyme labelled anti antibodies to a colourable product for detection. The sample is introduced into the upper chamber where the antigen etc. lands onto the enzyme labelled bodies and inert substance. The membrane is then broken and the solution passes to the filter. The uncomplexed specific enzyme labelled anti antibodies pass through and come into contact with the substrate in the chamber. The resulting coloured product can be removed for visual examination.

Abstract: A mechanical injection pump governor is provided having a first adapting device which acts in the lower speed range up to the full-load characteristic curve of a supercharged diesel engine for adapting the delivery quantity of the injection pump to the fuel requirement of the diesel engine. The adapting device contains a spring-loaded diaphragm which is acted upon by a supercharge and is connected to the control rod of the injection pump. The lift of the diaphragm, when supercharge pressure is applied, is limited by a full load stop which determines the adapting end point. To improve the torque profile of the diesel engine, a second adapting device is provided which adjusts the full load stop. By means of this second adapting device, the full load stop can be displaced against an additional spring force when supercharge pressure is progressively applied so that the delivery quantity of the injection pump increases between the adapting end point and the rated speed of the diesel engine.

Abstract: Disclosed is a compensator applicable for use with a traveling block supported from a mast, derrick or the like by means of a crown block wherein the traveling block may be utilized for supporting objects. Two fluid pressure piston-and-cylinder assemblies are arrayed on opposite sides of a line of travel of the traveling block relative to the crown block so that a flexible line positioned about the sheaves of both blocks passes over a pulley supported by one fluid pressure assembly to one side of the line of travel and, on the other side, the flexible line passes over a pulley supported by the other fluid pressure assembly. One end of the flexible line may be anchored relative to the mast as a deadline while the line at its other end may be selectively retracted or payed out by a drawworks or the like fixed relative to the mast. In one embodiment, the pulleys are carried by a carriage which is carried by the fluid pressure assemblies. The crown block is supported by flexible lines passing over pulleys also supported by the fluid pressure assemblies. In another embodiment, the fluid pressure assemblies directly support the crown block, and pulley assemblies are supported by flexible lines between the crown block and the mast, and include pulleys over which the flexible line connecting the two blocks passes. With the drawworks holding the first flexible line fixed, the crown block and the traveling block may move in unison relative to the mast with proportional reciprocable movement on behalf of each of the fluid pressure assemblies while the traveling block remains stationary relative to the crown block. Operation of the drawworks to retract or pay out the line results in manipulation of the traveling block relative to the crown block regardless of movement of the two blocks relative to the mast.
