A multi-use die system (10) is provided having a die holder (20) with reference marks (20r, 20c) disposed circumferentially and radially along the longitudinal axis of the holder, and a multi-use die plate (30) for magnetic affixation to the die holder (20) which impresses a pattern onto a material blank. The die plate has a straight and angular reference marks (60, 62) disposed thereon which are adapted to align with the radial and longitudinal reference marks on the die holder so as to properly align the die on the die holder (20) at a predetermined position. In a straigth rotary die system, the die is aligned such that the straight reference mark (60) on the die is aligned with the respective corresponding radial and circumferential references on the die holder. In the angular rotary die system, the die is aligned such that the angular mark (62) is aligned with the corresponding radial and circumferential references on the die holder.

An in situ underground sample analyzing apparatus for use in a multilevel borehole monitoring system is disclosed. A casing assembly comprising a plurality of elongate tubular casings (24) separated by measurement port couplers (26) is coaxially alignable in a borehole (20). The measurement port couplers (26) include an inlet measurement port (70b) for collecting fluid from an underground measurement zone (32) and an outlet measurement port (70a) for releasing fluid into the measurement zone (32). An in situ sample analyzing probe (124) is orientable in the casing assembly. The in situ sample analyzing probe (124) includes inlet and outlet probe ports (148b and 148a) alignable and mateable with the inlet and outlet measurement ports (70b and 70a). The inlet and outlet measurement ports (70b and 70a) typically include valves. When the operation of the in situ sample analyzing probe (124) causes the valves to open, the interior of the in situ sample analyzing probe (124) is then in fluid communication with the exterior of the measurement port coupler (26).

A container comprises a flexible body member (2) closed by a cap portion (26) having an outlet (28) therein, and a control assembly within the cap portion for controlling liquid flow from the body member (2) to the outlet (28), the control assembly comprising an integrally moulded seating (6) for location on the body member (2), including an outer annular sleeve (8) and an inner valve support chamber (12) and a control valve (16) of a one piece plastic moulding located on the seating (6) to define a closed volume therebelow and to seal the outlet, the closed volume being vented to atmosphere, the arrangement being such that, on pressurisation on the interior of the body member (2), the pressurised liquid flows between the sleeve (8) and the chamber (12) to distort the control valve (16) and enable flow through the outlet (28), and, on release of said pressure, the control valve (16) returns to a position sealing the outlet (28).
摘要:
In the field of CrMoV heat-resistant alloys for use in turbine rotors, in order to provide a low-alloy steel which has a toughness at the same level as conventional materials and has excellent high-temperature strength properties, particularly inhibition of creep embrittlement, and in order to provide a process for producing such a low-alloy steel and a turbine rotor in which such a low-alloy steel is used, trace impurities of phosphorus, sulfur, copper, aluminum, arsenic, tin, and antimony in a CrMoV heat-resistant alloy are reduced to specific levels or lower. In addition, trace impurities such as cobalt, niobium, tantalum, nitrogen, and boron are added to increase the creep strength according to a test using an unnotched test piece. In addition, according to the production process, quenching is carried out after heating to 1000°C or higher so as to inhibit precipitation of pro-eutectoid ferrite phase.

In a plate-type heat exchanger provided with a plurality of heat exchanger elements (4) each constructed of a pair of elongated plates (2, 3) each of which is provided with a pair of inlet/outlet openings (1) in its opposite end portions, a corrugated spacer member (5) for reinforcing each of the inlet/outlet openings (1) is reduced in weight and improved in heat exchanging properties. The spacer member (5) assuming an annular corrugated shape is interposed between vertically aligned adjacent ones of the inlet/outlet openings (1) of the stacked elongated plates (2, 3) in the heat exchanger element (4). This corrugated spacer member (5) is constructed of a metal plate corrugated over its entire circumference.

Methods and apparatus of integrating multimedia materials with didactic printed materials (25) present selected relevant multimedia material in response to the sensing of control codes (29A, 29B) embedded in context sensitive and/or content sensitive didactic printed material (25). A store (31, 51) of multimedia information is created, and the store (31, 51) is correlated to related context and/or content sensitive didactic printed material (25). The store (31, 51) is categorized to transmit certain categories (35, 37, 39, 49A, 49B, 49C, 49D) of the stored information from the store (31, 51) to a multimedia display (41) in response to the reception of certain input signals obtained from certain codes (29A, 29B) embedded in the didactic printed material (25). The printed didactic material (25) controls the display of multimedia material. Either preexisting didactic printed material or currently created didactic printed material can be efficiently and economically integrated with multimedia materials to display certain selected multimedia materials at sensitive places of the printed materials (25).
