Title: Adjustable mold for concrete median barrier
Inventor: SMITH PETER J
IPC: B28B7/10
Filed: 1987-01-09
Granted: 1991-07-30
Abstract: ABSTRACT OF THE DISCLOSURE      An adjustable mold for casting asymmetric concrete highway divider sections includes a fixed sidewall, a movable sidewall, and two end walls.  Each of the end walls is divided vertically into a first fixed panel and a second adjustable panel.  The mold can be set up to produce a barrier section that accommodates any difference in grade levels between the separated roadway lanes, within a preselected range, by adjusting the height of each second end panel relative to the adjacent first end panel and by adjusting the height of the movable sidewall to match the second end panels.  All adjustments are made by means of simple jack screws. The end walls and the movable sidewall are mounted on hinged frames that can be swung open to facilitate removing a section casting from the mold.

Title: Stacking method and apparatus
Inventor: WATTS LEONARD A
IPC: B65H33/16
Filed: 1987-05-27
Granted: 1992-08-18
Abstract: ABSTRACT OF THE DISCLOSURE      A self-adaptive stacker comprised of infeed and stacking sections whose movement is coordinated to provide interception of the signature stream.  The infeed conveyor section "Vees" the in-coming signature stream through the use of rollers of different diameters mounted upon straight, spaced, parallel shafts.  A microprocessor utilizes a signal, representative of the infeed conveyor speed, together with a signal from a signature counter, to track the movement of each signature and thereby its arrival at the intercept position.  Low armature inertia motors drive the three axes, (stacking section, the turntable, and the ejectors) to provide rapid starting, acceleration, deceleration, and stopping at selected positions.  These motor are controlled to interact in real-time in order to adapt the three axes to the rate of the incoming signatures.  The movement of the signature carriers is altered, when necessary, due to speed changes of the signature stream.  A sensor located at the intercept ready posi-tion detects the passage of a signature carrier to initiate acceleration of the signature carrier by an amount which is a function principally of signature thickness, velocity and separa-tion distance to control the amount of acceleration required to move the carrier beneath the first signature of the next stack to be formed.  The load current of the stacker motor is monitored to detect the occurrence of a jam which condition is prevented from damaging the stacker section conveying assembly by halting and

Title: Method and an apparatus for boosting battery
Inventor: REID DONALD
IPC: H02J7/00
Filed: 1987-10-27
Granted: 1992-05-26
Abstract: ABSTRACT        When boosting a battery, a direct current boosting voltage is applied between the positive and negative termi-nals of the battery via a pair of cables of predetermined length.  In order to supply a boosting voltage of predeter-mined constant value, a direct current voltage source supplies the boosting voltage to the battery not only through the pair of the cables, but also through a high current adjustable load.  Of course, the direct current voltage source supplies a voltage of value higher than the boosting voltage predeter-mined value.  A voltage controller detects the voltage bet-ween the ends of the two cables adjacent to the voltage source, and the voltage drop in the pair of cables, and varies the high current adjustable load in response to the detected voltage and voltage drop so as to adjust the boosting vol-tage at the predetermined constant value.

Abstract: ABSTRACT OF THE DISCLOSURE     A reflector-type microwave antenna includes a paraboloidal reflector and a feed horn located at the focal point of the reflector for launching microwave signals onto the reflector and receiving microwave signals from the reflector.  A supporting frame for the reflector and feed horn includes three arms extending along the rear side of the reflector to three spaced mounting locations on the rear side of the reflector.  The arms are fastened to the spaced mounting locations on the rear side of the reflector by fastening means having a loose condition in which the arm is attached to the reflector but free to move relative to the reflector, and a tightened condition in which the respective arm is rigidly attached to the reflector.  The fastening also includes swivel means for permitting tilting movement of the arm relative to the reflector surface when the fastening means is in the loose condition, and permitting the arm to assume different positions relative to the reflector when the fastening means is in the tightened condition.  In its preferred form, the fastening means includes a cupped member having a peripheral flange secured to the rear side of the reflector so that forces transmitted between the respective arms and the reflector are distributed over the area of the reflector encompassed by said flanges.

Abstract: COINJECTION MOLDED DAISYWHEEL PRINTHEAD          Abstract of The Disclosure A printhead is formed by injecting unfilled nylon by injection unit 1 and mineral filled nylon by injection unit 3.  The filling adds impact resistance for printing, while the unfilled nylon is particularly resistant to flexural fatigue near the hub of the printwheel.      Unit 1 is operated first to form an outer layer, with quantity limited so that the outer layer comes to about the middle of the arms of printheads.  Unit 2 is then operated to form a core and to be the only material forming the character elements.    The resulting printhead is durable and is capable of use at greater deflection than the same printhead made of only the impact resistant material.

Title: Folding polygonal toy construction element
Inventor: ZIEGLER JAMES T
IPC: A63H33/08
Filed: 1988-08-15
Granted: 1992-07-07
Abstract: Abstract A polygonal toy construction element is described having a substantially flat body portion with edge faces and top and bottom faces.  Each edge face has a plurality of outwardly projecting integrally formed connectors adapted to connect with corresponding projecting connectors of an edge face of another construction element in a snap-together lateral interlock between adjacent elements while permitting hinging action between connected elements on an axis parallel to connected edge faces.  According to the novel feature of the invention, the polygonal construction element has at least one line of reduced thickness extending across the element between at least two apices of the polygon to form a living hinge which separates the ele-ment into at least two face portions joined by a living hinge and at least one edge face.  This has the advantage of making possible a greatly increased variety of constructions while using only one modular edge length.

Title: Protective relay with selective phase selection for double lines
Inventor: BERGMAN STEN
IPC: H02H7/26
Filed: 1988-12-28
Granted: 1993-01-19
Abstract: ABSTRACT            The invention comprises a protective relay with selective phase selection in electric power distribution systems when there are double transmission lines (M1-P1,M2-P2) between two stations (TM, TP) and where the ends of the line are connected to a common busbar system located in each station.  The protective device comprises a protection unit, terminal, at both ends of each line. All the terminals (M1, M2, P1, P2) comprise an identical basic design comprising measurement of phase quantities (17), filter-ing (18) and A/D conversion (19).  Furthermore, the identical part comprises a parameter estimator (20) for Fourier series expansion of measured phase signals and generation of the respective residuals.  The parameter estimator cooperates with a frequency estimator (21) and a sampling regulator (22). Each basic design also comprises a local logic unit which, by means of a transient and steady state analysis, finds out whether an event on the network is due to a fault or a connection/dis-connection of the phase/line and the current direction at each terminal.  At one of the terminals, at both stations, there is a station master unit (26) which compiles all information for the station in question, calculates the distance to a fault, etc.  For final decisions as to whether a recorded fault lies between the stations, as to faulty line(s) and phase(s), all information from the two stations is compiled in a superordinate unit (29) in one of the terminals at one of the stations.
