Title: Interchangeable door panels for dishwasher
Inventor: MASON ANTHONY
IPC: A47L15/42
Filed: 1987-05-19
Granted: 1991-09-10
Abstract: ABSTRACT      A door frame is provided comprising a pair of laterally spaced,  vertically  directed  and  parallel  frame  members defining channels opening laterally towards each other.  A bottom frame member connects between the two side  frame members  and  defines  an  upwardly  opening  channel.   A decorative panel sheet is dimensioned so that it must be bowed slightly to present its opposite edges to the channels in the side frame members.  Upon releasing the panel, the edges penetrate the channel and are confined against fore and aft shifting.  The dimension between a control console on the top of the door and the bottom frame member  is greater than the spacing between the upper and lower edges of the panel.  This allows the panel to be unbowed without interference from the bottom frame member.  With the panel assuming  its  flattened  state  the  panel  can be  shifted downwardly into the channel in the bottom frame member.  A retaining strip holds the upper edge of the panel against the control console.   Preferably,  the retaining strip is arranged to be snap fit into place so that it can be readily removed when it is desired to change the exposed face of the door.

Title: Well pumping unit
Inventor: THOMPSON JAMES E
IPC: F04B47/02
Filed: 1987-10-15
Granted: 1991-03-05
Abstract: ABSTRACT          A pumping unit is disclosed having a shorter base frame than conventional pumping units and interchangeable crank arms, while retaining a relatively low net peak torque requirement obtained through a slower upstroke and a faster downstroke.  These advantages can be obtained in both the rear mounted and front mounted geometry systems with crank counterbalance.  The axis of the wrist pin connection between the pitman and the crank intersects a straight line direction extending through the center of gravity of the counterweight and along the axis of the crank arm to an intersection with the axis of the motor-driven spindle which rotates the crank arm.  This feature permits interchange of crank arm castings in a dual crank arm unit since each casting is identical.

Granted: 1993-11-09
Abstract: ABSTRACT            The room air conditioning method provides for a regulation or control of the fresh air volume supplied to the room and the removal of spent internal air from the upper room air layers. At least approximately room-isothermal fresh air is introduced in laminar manner into the room from the ceiling area.  The flow rate of the introduced fresh air assists the formation of room inherent dynamic partial flows.  The fresh air in the ceiling area is preferably supplied in the vicinity of room inner walls facing front walls.  A volume flow regulator is controlled in accordance with a temperature measurement on the laminar diffuser.  A heat exchanger     is preferably connected to the fresh air duct     in the ceiling area and is followed by a diffuser    .  The fresh air brought almost to room temperature in the heat exchanger is passed from top to bottom and directed in a substantially laminar manner into the room.  Through temperature adaptation of the room air with the aid of fresh air in the heat exchanger and the supply of isothermal fresh air with a low flow rate into the room, the comfort characteristics of the air conditioning apparatus are decisively improved.

Abstract: A B S T R A C T        A centrifugal processing machine for the mechanical processing, for example, grinding, polishing, cleaning and de-burring of workpieces, with a container serving to accommodate the work-pieces and processing agents.  The container comprises a substantially cylindrical casing and a rotating bottom, in the form of a plate or the like, mounted coaxially with the casing.  The peripheral edge of the bottom projects towards the cylindrical casing and forms a narrow gap.  For adjusting automatically the width of the gap around the entire periphery of the container, as a function of a given or varying gap-width, the casing is adapted to be raised and lowered in relation to the bottom.  This is accomplished by means of a measuring device, which measures the width of the gap, and by means of a device for raising and lowering the casing which is adapted to be controlled by the measuring device in such a manner that the width of the gap is adjusted to a specific value and is held at this value.
