Abstract: Abstract of the Disclosure An apparatus for feeding and receiving fanfolded paper to and from a printer comprises vertically arranged upper and lower trays and a pair of vertical support members connecting the upper and lower trays and supporting the upper tray thereon.  The apparatus is arranged and disposed for table or desk mounting behind and on the same level as the printer.  The upper tray is normally inclined upwardly from front to rear in a range of 10 to 15 degrees from horizontal so as to permit the paper to fanfold into the upper tray as the paper is received from the printer without having to manually fanfold the first sheet.  The upper tray is pivotally attached to the support members at the rearward end while the front end of the upper tray adapted to be supported upon the printer, and each of the support members define a plurality of vertically disposed apertures for attaching the upper tray at different heights in order to accommodate differently sized printers.

Abstract: Abstract of the Disclosure An electrical circuit for a resistance welder comprises 2 rectifier connected to an AC source, typically of 60 Hz.  If the source is a three-phase source  it is convenient to apply the source voltage to a full-wave bridge rectifier to produce an output voltage that has both a DC and an AC component.  This output voltage is applied to a controlled thyristor inverter that transforms it into a wave that is substantially rectangular.  An electronic circuit controls the thyristor inverter to determine the length of time it operates, the relative pulse width of the rectangular wave, and other desired features of the inverted voltage.  The output of the inverter is applied to a step-down transformer which has a center-tapped secondary.  The secondary is connected through a full-wave rectifier to welding contacts that supply welding current and the necessary force to a workpiece to accomplish resistance welding.

Abstract: PHN. 11.025                 12 ABSTRACT:         The invention relates to a receiving arrange-ment 4-1 for SHF signals, comprising a rectangular waveguide filter 5 formed from resonators 10-1 to 10-4 arranged in cascade, a SHF signal arrangement 6 con-taining a microstrip circuit and microstrip to waveguide filter transition connected to this circuit.  Generally, such a receiving arrangement is not suitable for use in radiators comprising a partly shown polarization conver-ter 3 with two such receiving arrangements 4-1 each receiving one of two mutually orthogonally polarized signals.  When the prior art receiving arrangements are used in these radiators, the channel separation is inadequate.  According to the invention, an adequate channel separation is obtained by providing the micro-strip to waveguide filter transition in the waveguide filter and matching the filter 5 thereto.  As a result thereof, the receiving arrangement 4-1 becomes more com-pact and has a very low reflection and, in addition, it is no longer necessary to adjust the transition to the waveguide filter 5.  Preferably, dimensioning  is realized by the choice of the size in the axial direc-tion  of the end resonator 10-4 and/or the choice of the dimensions of the coupling aperture which connects the end resonator 10-4 to the adjacent resonator 10-3.

The first tier of the event memory includes a plurality of locations wherein each location corresponds to an increment of time.  Means are provided for selecting data stored in the first tier of the event memory at address locations corresponding to time data received from a timing mechanism.  Means are also provided for selecting the appropriate data stored in the second and third tiers. Means are provided for combining the data selected from the first, second and third tiers and executing a function in response to the zone and schedule information contained in the combined data in order to execute the function at the time indicated by the time data and in the zones indicated by the combined data.  The user-programmable clock is also responsive to the keyboard to sequentially route identical data which is entered from the keyboard to a plurality of memory locations in the first tier of the event memory wherein the addresses of the memory locations correspond to successive minutes of time. Means are provided for adjusting the duration of the function execution for each event identified by each memory location of the first tier of memory.  By adjusting the duration of the execution to a time period equal to the time increment of each memory location of the first tier, a function may be executed for a time period which exceeds the time increment represented by each of the memory locations of the first tier.

Abstract: ABSTRACT A sealing system for sealing the junction between a horizontal surface such as the top surface of a bathtub and two adjacent walls is disclosed. The sealing system seals the junction of the walls and a horizontal surface which are substantially mutually perpendicular and define two longitudinal joints, one vertical joint and a corner at the intersection of the joints. The system comprises two generally L-shaped sealing strips each with a pair of legs extending lengthwise parallel to one of the joints and each stopping a predetermined distance short of the corner. A corner piece has faces adjacent the horizontal surface and each of the walls, the faces being shorter than the predetermined distance. Two generally L-shaped flanges extend lengthwise beyond the ends of the faces, each of the flanges overlapping with the one of the L-shaped sealing strips. The overlap accommodates some variation from ideal in the length of the sealing strips.          An end cap covers an end of a sealing strip remote from the corner. The cap comprises a generally L-shaped flange contoured to overlap an outside portion of one of the stripy adjacent the end of the strip. A generally L-shaped end face extends from the L-shaped flange of the cap with one edge abutting one of the walls and one edge abutting the horizontal surface.  A pair of fingers extends longitudinally along an inside surface of said one of the strips, with the fingers extending one from each edge of the end face.
