Title: Weather window shield for automotive vehicles and the like
Inventor: MILLER EVELYN B
IPC: B60J1/20
Filed: 1990-03-07
Abstract: ABSTRACT OF THE DISCLOSURE       An optically transparent weather window shield is designed for automotive vehicles and the like to protect an occupant from wind, rain, and snow when the window opening it is received in has the glass down.  Primarily, it consists of a main body with a rain run-off channel and a downwardly angled front portion for wind and rain deflection.  A mounting member is secured to a side edge of the main body and the front portion, and an edge portion of the mounting member is force fitted into the window receiving channel of the vehicle mounting the shield.  The structure is also such, that it is installed without any fasteners and is easily removed when desired.  The device is transparent so as not to interfere with the vision of the driver while operating the vehicle.

Title: Roller resilient bearing
IPC: F16C27/06
Filed: 1990-07-09
Abstract: TITLE               ROLLER RESILIENT BEARING     APPLICANT           SALVATORE ANTHONY DILORETO     INVENTOR        Salvatore Anthony DILORETO     ABSTRACT      A resilient roller bearing wheel or disk is constructed by forming a compound sleeve with an inner annular core and an outer resilient surround.  Preferably, they are molded from thermosetting plastic wherein the outer surround is a resilient material, for example, a resilient thermosetting plastic, while the inner annular core can be a resilient thermosetting plastic of less resiliency than that of the surround or, a firm or hard thermoplastic core.  In any event, the inner annular core defines a bore sized to accomodate a roller bearing of the prior art together with means for removably securing the roller bearing in the bore whereby, on excessive wearing of the resilient surround, the resilient surround may be removed from the roller bearing and a new one replaced thereon so as to achieve full lifetime use of the more expensive roller bearing.

Patent CA-2027442-A1 (CA)
IPC: F16D27/112
Filed: 1990-10-12
Abstract: An electromagnetic clutch is disclosed which includes a clutch rotor having a first friction surface and an annular armature plate having a second friction surface. The first friction surface and the second friction surface face each other. A friction member is made of nonmagnetic material and is fixedly disposed within a second groove formed at the second friction surface of the annular armature plate. A first end surface of the friction member projects with respect to the second friction surface of the annular armature plate. The first friction surface of the clutch rotor is provided with a first annular groove to receive the projecting portion of the friction mem-ber. Therefore, the depth of the second groove becomes smaller. Consequently, a reduction of the number of magnetic lines of flux which radially penetrate through an annular portion of the annular armature plate at the location of the second groove is prevented. Thus, the magnetic attraction between the annular armature plate and the clutch rotor is increased without increasing the weight of the electromagnetic clutch.

The mounting structure includes a frame including a bay capable of accepting therein one first height drive or two second height drives which are smaller than the first size drive.  The bay includes first and second opposed side walls situated in spaced apart relationship.   First  and  second  stationary rail  guides  are fixedly  situated  on  the  first  and  second  side  walls, respectively,  to mate with corresponding side  rails of the first size disk drive.  First and second removable rail guides are  removably mounted on the  first  and second  side walls, respectively,  at a distance spaced apart from the first  and second stationary rail guides.  The first and second removable rail guides mate with corresponding side rails of the second size disk drive when the first size disk drive is not present in the first and second stationary guide rails.  The user is provided with flexibility in that a first height drive can be installed when the removable rail guides are removed from the bay so as to avoid interference between the first height drive and such rail guides.  Alternatively, the user can install one second height drive in the bay on the stationary nonremovable rails and/or a second height drive in the bay on the removable rails when such rails are installed in the bay.

Title: Method for crystallizing anhydrous fructose from its aqueous solutions
Inventor: HEIKKILA HEIKKI
IPC: C13B25/00
Filed: 1991-01-17
Abstract: Crystallizing anhydrous fructose by preparing an aqueous solution containing at least about 90% dry substance, the fructose content of the dry substance being at least about 90% by weight; seeding the aqueous solution at a temperature of 50-60°C; and cooling the resulting mass at a controlled rate and with continuous mixing such that the supersaturation of the liquid solution with respect to saturated fructose is less than a ratio of about 1.25 and the temperature difference between the warmest and coolest portions of said solution is no more than about 6°C. Cooling is accomplished in a crystallizer with a heat transfer surface of 5 mm2/mm3 or greater. This method enables large scale, high capacity, high yield production of crystalline fructose through the use of a crystallizer with optional heat and mass transfer properties.

Title: Method for making flexible retroreflective sheet material
Inventor: MARTIN DAVID C
IPC: G02B5/122
Filed: 1991-04-17
Abstract: A flexible retroreflective sheet material is formed by adhering a first face of a first flexible synthetic resin sheet material to a synthetic resin second sheet material by a first adhesive which preferentially adheres to the second sheet material.   On the second face of said first sheet material are thereafter formed closely spaced retroreflective microprisms having a height of 0.001-0.010 inches.  A second adhesive is applied to the second face of said first sheet and firmly engages therewith.   A flexible backing material is adhered to the second adhesive over the second face.  Lastly, the second sheet material and first adhesive are stripped from the first sheet material to produce a firmly bonded flexible composite sheet material comprised of the adhesively bonded first  sheet  material  and  backing  material.    The retroreflective microprisms may be coated with a reflective metal  deposit  or  surrounded  by  air  to  provide  a retroreflective interface.

Title: Syringe having means for retracting, canting and destroying a needle cannula
Inventor: HABER TERRY M
IPC: A61M5/315
Filed: 1990-10-12
Abstract: A disposable, safety syringe (1) having a conventional single ended hypodermic needle cannula (18) bonded to a central core (26) of a needle carrying hub (12) at the distal end of a syringe cylinder (2). A locking and retracting probe (14) extends proximally into the syringe cylinder from the central core of the needle hub.  A piston assembly (6) having an offset locking bore (10) is advanced distally through the cylinder to expulse fluid therefrom via the cannula and to receive the locking and retracting probe within the locking bore. A continued distal advancement of the piston assembly through the cylinder causes the central core to be broken away from the needle hub. Therefore, when the piston assembly is withdrawn proximally through the cylinder, the cannula that is bonded to said central core is correspondingly retracted within, canted and shielded by the cylinder to avoid an accidental needle stick and the spread of disease.
