Title: Clutch/brake
Inventor: MATSON ROBERT C
IPC: F16D67/04
Filed: 1988-04-11
Granted: 1991-12-31
Abstract: Abstract of the Disclosure A clutch/brake for alternatively connecting a rotatably driven shaft to a driving member and a stationary member has clutch plates operatively connecting the driven shaft and the driving member and brake plates operatively connecting the driven shaft and the stationary member.  A clutch operator for urging the clutch plates together is connected to rotate with the driving member.  A brake operator for urging the brake plates together is connected to rotate with the driven shaft.  A linkage connects the clutch and brake operators to move axially together and includes a bearing which transmits axial thrust loads statically when the clutch is engaged.  An annular pneumatic piston moves the clutch and brake operators in a first axial direction to engage the clutch, is connected to the outer bearing race and rotates with the driving member.          Brake springs bias the clutch and brake operators in a second axial direction opposite to the first axial direction to engage the brake and are connected to the inner bearing race.  A second bearing connects the driven shaft and the housing and is statically loaded with the force of the brake springs when the clutch is engaged.  A force exerted by the piston is transmitted through the linkage bearing in the first axial direction to disengage the brake and a force exerted by the biasing means is transmitted through the bearing in the second axial direction to disengage the clutch.

Inventor: SADR CHANGIZE
IPC: C08L23/16
Filed: 1988-09-13
Granted: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE In general, blow moldable or extrusion grade polyesters are quite expensive.  A relatively inexpensive blow moldable polyester composition can be produced by modifying a low or injection molding grade of polyester with sufficient elastomer to reduce the viscosity of the injection molding grade polyester to a level at which the latter can be blow molded.  For example, a copolyester prepared by transesterification using readily available starting materials such as dimethyl terephthalate polytetramethylene ether glycol and 1,4-butanediol can be mixed with an elastomer selected from the group consisting of ethylenepropylene diene terpolymer, ethylenepropylene diene terpolymer in combination with high density polyethylene, ethylene-vinyl acetate thermoplastic copolymer, and styrene-ethylene-butylene-styrene block copolymer to yield a relative inexpensive molding grade polyester composition.

Abstract: ABSTRACT OF THE DISCLOSURE          An attachment assembly for removably securing a module, for example an electronic display module, to conventional shelf tag moulding of the type comprising long, extruded aluminum strips affixed to the forward edge of a length of shelving. Specifically, the attachment assembly comprises a lever arm rotatably coupled to a mounting member.

Title: Airfoiled blade
Inventor: WAINAUSKI HARRY S
IPC: B64C3/14
Filed: 1989-01-17
Granted: 1993-07-27
Abstract: Abstract Airfoiled Blades A blade is comprised of a plurality of a family of airfoil sections, each section being characterized by a large leading edge radii, a camber having an apogee at approximately 45% of the airfoil section chord length and relatively blunt trailing edge. The airfoil sections taper in thickness ratio (h/b)  from about 20% near the blade root to about 2% near the blade tip.          The maximum thickness for each airfoil section increases along the chord length from about 39% of the airfoil section for a 20% airfoil section to about 42% of the airfoil section chord length of a 2% airfoil section.  As such, the novel blade of the invention provides superior aerodynamic performance to the NACA          Series 16 airfoil in the Mach 0.50 to 0.70 range with less susceptibility to foreign object damage and handling problems.

Title: Means for clamping fiber optical cable
Inventor: NEWELL EDWIN R
IPC: G02B6/25
Filed: 1989-09-11
Granted: 1993-10-19
Abstract: ABSTRACT OF THE DISCLOSURE   A fiber-optic switch uses a single optical fiber for two-way communication with light.  A switching mechanism has no electrical part and is thus appropriate for placement in an area having explosive or combustible materials.  The optical fiber can be cut to length in the field and can be installed without special tools or training.  The fiber is held in place by a clip that is constrained to compress the fiber and grip it securely.  A snap-action mirror reflects light back into the fiber in one position and does not reflect it in another position.  An electronic circuit provides pulsed light and determines coincidence of sent and received pulses to discriminate against operation of the switch by ambient light or other spurious signals.

Title: Disposable absorbent article having improved leg cuffs
Inventor: FREELAND MARY E
IPC: A61F13/15
Filed: 1989-09-29
Granted: 1994-12-13
Abstract: A disposable absorbent article, such as a diaper, is disclosed. The diaper has two lengthwise extending longitudinal marginal portions, each longitudinal marginal portion having two elastically extensible leg cuffs, a barrier cuff and a gasket cuff. The leg cuffs serve to help contain body exudates within the disposable article. Each leg cuff is elasticized to provide a relatively low ultimate contact force against the skin of the wearer at relatively high elongations. This arrangement provides a diaper with leg cuffs which can be elongated to conform to the shape of the wearer, without causing undue discomfort or irritation to the legs of the wearer. The relatively low ultimate contact force at relatively high elongations may be accomplished either through a low contact force differential material, or through a material which exhibits stress relaxation over relatively short period of time.

Abstract: A lead anode for electrowinning metals from sulfuric acid solutions is formed by soldering a sheet of lead anode material endwise in a slot, which extends longitudinally along and partially through a lead alloy coated copper bus bar and into which the sheet fits tightly, and thereafter depositing lead alloy filler at all joints between the bar and anode. Anodes thus constructed have a uniform, smooth joint between the bar and sheet and thus are corrosion resistant and exhibit uniform conductivity.
