Abstract: A B S T R A C T         To prevent the supply of interfering signals by peripheral plug-in modules of a digital telephone exchange, it is known to suppress the enable signals for such a period of time that after the supply voltage has been applied on plug-in a given time interval has elapsed and the supply voltage has reached a predetermined threshold value.  To keep interfering signals produced during operation at a safe distance from the time-division multiplex highway the use of circuit arrangements with monostable multivibrators is known.  It is then assumed that in the event of interferences the enable signals occur as continuous signals.  Should the channel allocator behave in a neutral manner to the exterior on switch-on, then an RC-circuit which produces a blocking signal for all the outputs of the channel allocator, is connected to a store.  To ensure a channel allocation which is correct with respect to time, a synchronization state supervising circuit is provided which comprises charge pulse generating circuits and counters and, on the basis of charge pulses or counting pulses, respectively, derived from the synchronizing signal and the plug-in position coding, effects the supervision of the synchronized state.

Abstract: ABSTRACT           An imaging system in which an imaging member comprising a substrate and an electrically insulating softenable layer on the substrate, the softenable layer comprising migration marking material located at least at or near the surface of the softenable layer spaced from the substrate, and a charge transport material in the softenable layer is imaged by electrostatically charging the member, exposing the member to activating radiation in an imagewise pattern, decreasing the resistance to migration of marking material in the softenable layer sufficiently to allow the migration marking material struck by said activating radiation to retain a slight net charge which allows only slight agglomeration, slight coalescence, slight migration in depth of marking material towards said substrate or combination thereof in image configuration during a further decreasing of the resistance to migration towards the substrate in image configuration, and further decreasing the resistance to migration of marking material in the softenable layer sufficiently to allow non-exposed marking material to agglomerate and coalesce substantially. This imaged member may be used as a xeroprinting master in a xeroprinting process comprising uniformly charging the master, uniformly exposing the charged master to activating illumination to form an electrostatic latent image, developing the latent image to form a toner image and transfering the toner image to a receiving member. A charge transport spacing layer comprising a film forming binder and a charge transport compound may be employed between the substrate and the softenable layer in order to increase the surface potential associated with the surface charges of the latent image.

Abstract: ABSTRACT OF THE DISCLOSURE           A light fixture including a louver assembled from blades formed of thin metal strips.  The blades each have separate parabolic lower sidewalls and upper sidewalls.

Abstract: ABSTRACT     This invention relates to a word synchronization system which receives signals with error correction codes to calculate a syndrome from an initial phase, changes the initial phase when the calculated syndrome is not zero to calculate it anew, and repeats the operation until the time when the particular syndrome becomes zero for the sequence of M time (or the number of testing stages).          This invention system is further provided with a synchro-nization slip detecting circuit to judge such a slip out of the synchronization without the necessity to wait for the repetition of the state for M times to thereby enable prompt phase resetting or synchronization establishment.     - Abstract -

Abstract: ???????.           ????? ????                   Haifa, Israel Assignee:          National Research Council of Canada Ottawa, Canada Abstract An implantable plate for joining together two pieces of a broken bone is formed to have a plurality of elongated holes for the screws that fasten the plate to the bone on both sides of the fracture.          The screws are positioned at the end of the elongated hole that is farthest from the fracture.  The portion of each elongated hole that is not occupied by the screw is filled with a cushion of elastic material that may be deformed elastically when the screw shank is pressed against it, thereby allowing lateral movement of the screw in the hole.  When the plate is implanted in the body of a person and fastened to a fractured bone by means of screws through the elongated holes, the plate stabilizes the bone pieces but permits the screws, and hence the bone pieces, to move a short distance back and forth in the direction of the axis of the bone in order to promote healing.

Abstract: A safety control system for an electrically operated hospital bed utilizes a wireless disconnect signal from an above mounted safety light to an outlet below which supplies electrical power to the bed, thereby to interrupt power to the outlet upon the detection of physical contact with the safety light, as perhaps caused by an IV pole raising with the bed.          In a preferred embodiment, a two-way transmission path is utilized to verify no blockage of the line of sight transmission path between the outlet and the light, with power to the outlet being disconnected upon contact with the light or blockage of the line of sight path.

Inventor: HOSHINO YOSHIHIRO

Granted: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE           A high hat stand for a pair of cymbals, including a support for a stationary cymbal and a vertically slidable coaxial operating rod for a cooperating movable cymbal.  A spring returns the movable cymbal off the stationary one.  A foot pedal operates the movable cymbal against the stationary cymbal.  The connection between the foot pedal and the movable cymbal comprises a rotary member connected to and movable by the foot pedal and connected to move the operating rod for the movable cymbal.  From the axis of rotation to its point of operative connection, the lever arm of the rotary member connected to the foot pedal is longer than the lever arm of the rotary member connected to the operating rod of the movable cymbal. The rotary member is defined either by a lever or a wheel.  An additional swingable arm may be connected to the axis of the rotary member to enable the axis to swing with respect to the movable cymbal operating rod when the connection from the rotary member to the rod swings through an arc.  This reduces the effect of lateral bias on the rod due to swinging of the lever as it rotates around its axis.
