A shock absorber for damping the relative movement of the sprung portion of the automobile with respect to the unsprung portion of the automobile. The shock absorber includes a pressure cylinder and a piston disposed within the pressure cylinder. The piston is able to control the flow of damping fluid between the first and second portions of the working chamber so as to generate firm and soft damp...

A monoflow shock absorber (30) is provided with a blow off valve (104) which provides the principal flow restriction during both extension and compression of the shock absorber (30). The force biasing the blow off valve (104) closed is controlled by a control piston (124) which is connected to the blow off valve plate (104) by a rigid, solid rod (108). The piston (124) responds to a pressurized co...

A method for eviscerating pig carcasses comprising insertion of a plug into the anus of the carcass in order to avoid contamination of the carcass. Before the plug is inserted into the anus it is cooled down to a low temperature, such as below -20 C. The plug will freeze on to the area around the anus sealing the anus tightly. In this way the casing contents will not flow out during the cutting...

The highly absorbent, leak-proof and breathable diaper of the invention is a 3-layer fabric incorporating a first layer of terry cloth, a second layer of polyurethane film, and a third layer of woven, or knit, fabric. Both the first and second layers, and the second and third layers, are laminated together with a urethane adhesive. The first layer then serves as a fluid absorbing portion for the d...
