Portion (13b) threadedly engages the packing cartridge (14) and has an inner shoulder surface (13c). The packing cartridge (14) has an inner end face (14d) contacting the shoulder surface (13c), and an exterior threaded cylindrical surface (14c) for engagement with mating threads (13d) on the pump fluid cylinder recess (13). An end face (14d) of the packing cartridge (14) has an indented portion about the periphery of the interior edge (14e) thereof. An O-ring seal (65) is disposed in the indented portion and creates an effective high pressure seal between the packing cartridge nut (14a) and the pump fluid cylinder means (12). A front bushing (18) is designed to increase the volumetric efficiency of the pump head.

Abstract: In a switching mechanism 1 of a protective switch, it is proposed that the bell crank 8 and the tripping lever 10 form such an angle with respect to one another that the resulting force on the latch and on the tripping movement B of the impact armature 14 are both smaller when making contact with the contact parts 3 and 4 than in the fully switched-on state of the protective switch. The individual parts of the switching mechanism 1 are designed to be compatible with automata. A guide clip 12 and a guide 13 in the base part of the housing 2 ensure that the switching mechanism is not tilted, even when the housing is open. <IMAGE>

Abstract: A folding machine capable of use with a reinforcing tape inserted in the fold of the workpiece edge has a tape feed arrangement (70) comprising a continuously rotating cylindrical or convex roll (76), which is located between a supply (reel R) and an operating locality of the machine, and which provides a low-friction surface over which a single turn of tape (T) can be wound, guides (80) being provided for preventing the tape on said surface from binding on itself. In operation, the application of a pulling force to the leading end of the tape (T) causes the single turn to tighten on the surface of the roll (76) and in turn apply a drawing force to the tape to draw it from the reel (R). The relaxing of the pulling force on the leading end discontinues the drawing of tape from the reel.

Abstract: The hepatitis B virus preS2 antigen gene linked in one contiguous reading frame to the hepatitis B virus surface antigen gene has been expressed in  Saccharomyces cerevisiae  utilizing an optimized plasmid construction. The expressed protein aggregates into a particulate form which displays the major antigenic sites encoded by both domains, thereby highlighting the utility of yeast as a host for the high level expression of the preS2 as well as the S domain. This protein is useful in  in vitro  diagnostic systems and as a vaccine for the treatment and prevention of hepatitis B virus-induced diseases and/or infections.

IPC: G02F1/13

Abstract: An improved light modulating material for use in electro-optic and thermo-optic display devices is produced by forming a homogeneous solution comprising a acrylic resin containing active hydrogen groups, a liquid crystal material, a diisocyanate or epoxide, and a solvent. The homogeneous solution is preferably applied to a conductive substrate and the solvent is then evaporated, causing phase separation resulting in formation of a liquid crystal phase dispersed within a solid polymer matrix. Application of an electric field to the substrate causes the liquid crstal material to align, which in turn causes the coating to switch from substantially translucent to substantially transparent. If the electric field is removed the light modulating material again becomes substantially translucent. Switching times can be improved by incorporating a titanate or zirconate organometallic material into the light modulating material.

Abstract: A piezoelectric bimorph is formed by uniformly poling a homogeneous sheet of piezoelectric material in a first direction and thereafter establishing a substantially linear temperature gradient across the sheet while concurrently applying a reverse poling field across the sheet of a magnitude selected for substantially depoling the middle layers of the sheet, poling the hotter layers in the reverse direction and leaving the cooler layers poled in the first direction. The impedance of the piezoelectric material is monitored to terminate reverse poling when the otter and cooler layers are substantially equally poled.

Abstract: Press connection of a connection piece of a tap (1) or of a fitting of cast metal to a conduit (5) whose crushing yield point and modulus of elasticity are greater than those of the connection piece (2). The wall thickness of the piece (2) is so dimensioned that it can be pressed onto an elastic conduit (5) adapted to its internal diameter. Since, for example, in the case of a plastic or copper conduit the crushing yield point and the modulus of elasticity of the conduit are smaller than those of the piece (2), an elastic support sleeve is pushed into the pipe, its crushing yield point and modulus of elasticity being greater than those of the piece (2), pressing the plastic conduit sealingly against the piece (2). <IMAGE>

Abstract: A plasma etching system includes a radio frequency generator (12) and a parallel plate plasma reactor vessel (14). A phase inverter circuit is used to couple the RF generator to the electrodes (19, 21) in the plasma reactor (14) so that the electrodes (19, 21) are driven with voltages of substantially equal magnitude but which are 180° out-of-phase. In this way, a maximum potential difference between the electrodes can be achieved while minimizing the potential difference between the individual electrodes (19, 21) and the reactor vessel (14). Such operation allows higher power levels with reduced occurrence of arcing and stray discharge, and provides a stable, uniform plasma discharge.

Abstract: An apparatus for exposure of an image of an original film (31) on a photosensitive material (32) held together with the original film (31) by vacuum contact between a transparent plate and an elastic sheet. The apparatus includes a squeegee unit (11) which moves while pressing the elastic sheet (1), for forcedly moving the air, thereby speeding up the setting of the vacuum contact, and a speed changing unit for changing the moving speed of the squeegee unit dependent on ease of movement of the air. If the air easily moves, the squeegee unit moves rapidly. If it is not easy to move the air, the squeegee unit moves at low speed, or the squeegee unit stops for a prescribed period and after the air is removed, it restarts to move. Thus, the removal of the air is carried out rapidly and there remains no blowhole.
