Abstract: A printer apparatus having two-sided printing capability is taught. Two printing mechanisms (14, 15) are provided that can simultaneously print both sides of roll paper (13). The printing mechanisms are physically oriented with respect to each other and to a simple paper handling/routing mechanism comprised of rollers so that when only one printing mechanism (14) is installed to provide only one-side printing, the paper handling mechanism need not be modified but the roll paper (13) is merely routed differently around the rollers. Retroactively, a second printing mechanism (15) may simply be installed in the printer for two-sided printing and the roll paper is routed around the rollers differently to route the roll paper to and from the second printing mechanism.

Abstract: An improved process is provided for the preparation of siloxane-oxyalkylene copolymers by a solventless process via hydrosilation of oxyethylene-rich polyethers in the presence of carboxylic acids or carboxylic acid salts as a catalyst modifier. The use of a carboxylic acid or salt prevents acetal formation through the hydroxyl groups of the polyether and/or copolymer. The use of solvent, acetal treatment and solvent stripping steps of the conventional processes are eliminated and accordingly, environmental as well as economic benefits are achieved.

Abstract: Pressure relief poppet valves (72, 74) vent the pressure on a piston (22) at the end of the work stroke. The poppet valves are carried by the piston and have a valve seat (82) and a valve member (84) movable in the valve seat. An adjuster tool (192) is used to shorten the maximum work stroke defined by the poppet valves. The tool includes a member (202) which engages the seat (82) of the first poppet valve (74) to move it inwardly relative to the piston (22). This moves the seat of the second poppet valve (72) outwardly relative to the piston, the adjusting movement being transmitted by tubular member (104). Adjustment of the opening stroke of valve (74) is done by screwing in of member (202) until it protrudes a desired length from housing face (120).

Abstract: An orthopedic device suitable for controlling hip joints is provided which includes a first hinge means (10, 22, 36) for flexion and extension of the hip and a second hinge means (20, 31) for abduction and adduction of the hip. The orthopedic hip hinge permits a shortening of the overall length of the hinge arm assembly during abduction of the hip and minimizes pistoning of the thigh attachment support. Also included are means for permitting free abduction of the orthopedic hinge within a specified range, while preventing any adduction of the hip. The disclosed device more closely approximates the actual motion of the femoral head in its socket, since the flexion hinge and the abduction hinge employ a common element, and are disposed in a ball-joint arrangement.

Abstract: The invention relates to a tool-changing device (13) for a profiling apparatus comprising three profiling machines (1, 11, 12) of open-side design. The tools (4, 5, 9, 19), which are each arranged on one outer side of the profiling machines are simultaneously withdrawn from the latter and pushed onto axle-stub-shaped tool carriers (31-36) on the changing device. For each tool on the profiling machines, two tool carriers (21-26, 31-36) are provided on the tool-changing device (13). These tool carriers are all arranged on a common support (28). One set of tool carriers (31-36) is initially empty and, when the tools are changed, takes over the used tools. After the transfer (20- 30) of a support (28) guided like a slide in a rocker (29), the second set of tool carriers (21-26) is situated opposite the tool carriers on the profiling machines, onto which the new tools are then pushed. For the tool change, the rocker (29) is raised into the working and operator side of the profiling machines. During the operation of the profiling apparatus, the rocker is pivoted back and leaves the profiling machines free on their operator side. <IMAGE>

Abstract: Method and apparatus adapted for use on a conveyor line to form a rolled tab (20) in the tail end (16) portion of a roll (10) of polymeric film wound on a core (12). The tail end portion initially extends around the surface of the roll to which the tail end portion adheres and terminates at a tail edge (18). The apparatus comprises a bucket (32) which is connected to the conveyor line for movement thereon and has a floor (34) and wall (37) extending therefrom. The floor of the bucket has a tractional surface (35') supporting the roll and the wall has a substantially frictionless surface pushing the roll in the direction of the conveyor line. The apparatus further comprises drive means (40), extending in stationary position substantially parallel to the conveyor line and having a resilient tractional surface being compressed into rotational contact with the roll, for rotating the roll. The drive means rotates the roll to rub the surface of the roll against the tractional surface of the floor which separates the tail end (16) portion from the surface of the roll and rolls the tail edge back on the tail end portion to form a rolled tab containing the tail edge.

Abstract: A memory cell array (MCA) includes a plurality of static memory cells (MC) arranged in a matrix form and selectively controlled by means of word lines (WL) to output complementary memory data to paired bit lines (BL,  BL ). An address transition detecting circuit (20) generates an address transition signal (φ ATD ) in the form of a monostable pulse having a constant length when detecting the transition of an address signal (X0, X1,..., Y0, ...). A bit line initializing circuit (6) initializes the potentials of the paired bit lines (BL,  BL ) in synchronism with the address transition signal (φ ATD ). A pulse width extension circuit (21) sets the pulse width of the address transition signal (φ ATD ) generated from the address transition detecting circuit (20) to be longer in the write mode than in the readout mode.

Abstract: In the case of such a position measuring device, the division (T) of a division carrier (TT) is scanned by a scanning device (A) in order to generate two periodic scanning signals (Sa, Sb), which are converted by means of two measurement triggers (MTa, MTb) into two binary measurement signals (MSa, MSb) and transmitted via two measurement signal lines (SLa, SLb) to an evaluation device (W). Provided in the scanning device (A) is an error signalling device (F) for monitoring the signal parameters of the two periodic scanning signals (Sa, Sb), the error identification signal (FS) of which is likewise transmitted to the evaluation device (W) via an error signalling line (FL). For the purpose of activating a test device (PE) for checking the trigger threshold voltages of the two measurement triggers (MTa, MTb), an activating signal (U) is applied in the evaluation device (W) to a circuit element (SE), which inverts the signal state on the error signalling line (FL). This inversion of the signal state is identified in the scanning device (A) by a comparator stage (AG), which is applied to the test device (PE). <IMAGE>
