Abstract: Abstract A low-profile, high-density package for integrated circuit chips is provided.  A first multichip memory module includes first and second interconnect members having low-profile memory chips mounted on a first side of each member.  Low-profile edge clips are employed to mechanically connect a second side of the second member to a second side of the first member, and to electrically connect the first sides of the members to a first surface of a circuit board.  Likewise, a second multichip memory module includes first and second interconnect members having low-profile memory chips mounted to a first side of each member.  Low-profile edge clips are employed to mechanically connect the second sides of the members, and to electrically connect the first sides of the members to a second surface of the circuit board.  A thermal management technique that distributes thermal loads is thereafter applied to create a high-density package capable of insertion into a standard computer backplane and cabinet.

Patent CA-2053353-A1 (CA)
Inventor: CARON NORM
IPC: A01D45/02
Filed: 1991-10-11
Abstract: A mechanism for adjusting the stalk-receiving gaps between  stripper  plates  in  a  produce  harvester.    The mechanism is adpated for use in harvester where a number of pairs of stripper plates are utilized, and where a space is formed between adjacent pairs of stripper plates,  and a stalk-receiving gap is formed between the stripper plates within each pair.  The mechanism permits all stalk-receiving gaps in the harvester to be adjusted simultaneously and to the same degree.  These gaps are adjusted from both sides allowing for optimum centering of the gap to engage the stalks.    The mechanism comprises  a  reciprocating  shaft disposed so as to move substantially perpendicular to the movement of the harvester.  A number of rotating shafts are connected to the reciprocating shaft and these are disposed within the spaces between adjacent pairs of stripper plates.          The rotating shafts are disposed substantially at right angles to the movement of the harvester.  Each rotating shaft is connected to the stripper plates on either side of the space between the adjacent pairs of plates by linkage arms.          As the reciprocating shaft is moved, the rotating shafts rotate or roll, causing the stripper plates on either side of the spaces between adjacent pairs to move towards or away from each other, depending on the direction of movement of the reciprocating shaft.   This movement causes the stalk-receiving gaps to be increased or decreased in size.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved lower suspension ball or collet for a washing machine hung suspension system,  the collet providing an axial channel for receiving a hung suspension rod therethrough,  the collet supporting a portion of a floating base which holds the vibration inducing components, such as rotating washing machine components, the suspension rod attached at its top end to a frame such as a washing machine cabinet, the collet resiliently supported off of a bottom end of the suspension rod, the collet channel fashioned to act as a friction bushing in a spring-mass-damper arrangement.  The collet comprises a tube portion having the axial channel which grips the rod to act as the friction bushing.  The channel has an inside diameter smaller than an outside diameter of the rod.  The tube portion provides two axially arranged slots cut therethrough offset by 90°.  The slots begin at opposite axial ends of the tube portion and terminate shy of the respective opposite axial end of the tube portion.  The axially arranged slots provide sufficient flexibility or stretch to install the rod through the axial channel.  A squeezing of the collet under axial load occurs during use, tending to open up the inside curvature of the tube portion channel to conform with the outside diameter of the rod.

Abstract: In a towel dispenser, a selection can be made between a standard program, in which, to form a towel loop, first a portion of unused towel and subsequently a shorter portion of used towel is released, and a hygiene program, in which only unused towel is released. In both cases, a movement sensor monitors whether the towel is moved as a result of external action, and if this is so the towel portion is drawn in as used 3 seconds after the movement has ceased.      If the towel, after being dispensed, is not moved for 20 seconds, it is retracted as unused.        In both cases, economy programs with a dispensing of shorter towel portions can be selected.        Within the standard program, a selection can be made between a normal program, in which used towel is first drawn in and subsequently unused towel is provided, and a fast program, in which the dispensing of unused towel takes place first.        Where the tripping of towel dispensing is concerned, a selection can be made between a trip by the movement sensor, which, in the state of rest, detects movements imparted to a short loop, or a trip by an infrared sensor.      In the fast program, the towel dispensing takes place without a trip.

Abstract: THREADED RECEPTACLE METHOD AND DEVICE     ABSTRACT OF THE DISCLOSURE    A molded receptacle including an interior wall surface and screw threads formed on the interior wall surface by a mold core.  The threads have a predetermined thread profile including root radii substantially corresponding to a desired thread standard and crest radii which are smaller than the root radii.  The crests of the threads are defor-mable after molding to enable the mold core forming the threads to be stripped from the receptacle in a direction substantially perpendicular to the major axis of the threads to provide crests which are deformed from their original molded shape yet dimensioned to fall within the desired thread standard.  The receptacle is utilized as a threaded socket having one or more electrical contact members.  The socket includes a housing which can be formed as stated above including an interior side wall having the threads, a first closed end, a second open end and a first aperture formed through a portion of the housing.  A first substan-tially flat electrical contact member extends through the first aperture and includes a first portion extending out-wardly away from an exterior surface of the socket and a second portion extending onto the interior of the socket.          The first contact member is fixed to the socket by manipulation of the first contact member with respect to the socket and provides resilient engagement between the first portion of the first contact member and an article to be threadingly inserted within the socket.
