Abstract: A sleeve-type beverage can carrier having a transversely arranged handle opening in the top panel. The opening is covered by flaps foldably connected to the top panel along the transversely extending elongated edges of the handle opening, each flap being formed of individual tabs which facilitate the folding down of the flap by the fingers of a user. The elongated edges are tapered so that they are the most widely spaced apart midway along their length and the closest together near their ends. This arrangement causes the top panel on both sides of the handle opening to bow upwardly when the carrier is lifted to distribute the lifting stresses through the top panel and the upper portions of the side panels.

Abstract: Described is the use of oleophilic esters of ecologically compatible polycarboxylic acids with oil-soluble and ecologically compatible monofunctional alcohols and/or polyfunctional alcohols which may also be watersoluble as the oil phase or as a component of the oil phase of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The oleophilic polycarboxylic acid esters are especially suitable as component of the continuous oil phase of inverted fluids of the W/O type. Here-if rheologically suitable compounds will be employed-they may comprise the at least predominant portion of the continuous oil phase; but also possible is the concomitant use of complex oleophilic polycarboxylic acid esters, which are not or just to a restricted degree fluid in a temperature range of from 0 DEG  C. to 20 DEG  C., as an additive in fluid oils of the class of the non-polluting oils. Here, suitable oil mixing phases especially are oleophilic alcohols, ethers, respective esters of monocarboxylic acids and fluid oils based on oleophilic carbonic acid diesters.

Abstract: A mechanism for detachably mounting any selected one of several attachments to a hollow spindlehead ram within which a spindle is rotatably supported by a hollow shaft, the latter being capable of both rotary and axial displacement relative to the ram.  Both the hollow shaft and the selected attachment are coupled with the ram via Curvic coupling teeth.   Further, in order to retain the attachment in positive engagement with the ram via the Curvic coupling teeth, a series of external locking teeth are  formed  on  the  hollow  shaft  at constant circumferential spacings for engagement with a series of internal locking teeth formed on the attachment.   The hollow shaft forces the attachment against the ram via the interengaged locking teeth under hydraulic pressure.

Abstract: An apparatus and method for dehumidifying air includes a duct with at least four ports, two at each end. The ports are regulated by valves that are biased in the closed position. A desiccant containing matrix is disposed within the duct. One or more fans are adapted to produce substantially axial air flow in two directions through the duct: a first direction during a regeneration phase of the dehumidifying cycle and a second direction during a process phase of the dehumidifying cycle. In the process direction, air from the enclosure enters one end of the duct, passes through the desiccant containing matrix where moisture is absorbed by the matrix and exits through the opposite end of the duct back to the enclosure. The air is thus at a lower relative humidity when it leaves the apparatus. Upon reversal of the air flow direction, the air is drawn into the duct from a source outside the enclosure, heated by a heater, passed through the desiccant containing matrix where moisture is absorbed from the matrix and exits through the opposite duct back into the source of air. The air is thus at a higher relative humidity when it is exhausted from the apparatus.

Title: Brushless dc motor

Filed: 1991-06-19
Granted: 1996-08-20
Abstract: Disclosed is a brushless DC motor which does not have a position sensor for detecting a rotational position of the rotor, in which conducting phases of the stator windings to be detected are subsequently selected by multi-phase selection signals in response to a conducting state of the stator windings, then a pulse signal train is generated by detecting the counter electro-motive forces induced in the conducting phases subsequently selected and a trapezoidal waveform signal is formed by a slant waveform signal generated in response to the pulse signal train thus obtained.   Furthermore,  with the trapezoidal waveforms signal thus formed as position signal of the rotor, an electric current signal having a trapezoidal waveform is supplied to the stator windings, resulting in smooth commutation of the con-ducting phase of the stator windings.  When to be started, phase commutation of the stator windings is carried out forcibly by means of a pseudo output pulse, thus being capable of providing a starting characteristic compatible with that obtained in con-ventional motors having a rotor position sensor.

Title: Matrix metalloproteinase peptides: role in diagnosis and therapy
Inventor: LIOTTA LANCE A
IPC: C07K7/04
Filed: 1990-03-01
Granted: 2000-08-22
Abstract: A family of metalloproteinases exist which cleave extracellular matrix molecules. These metalloproteinases are secreted in a latent inactive form and require activation in order to specifically cleave the preferred substrate. A series of peptides have been prepared based on the complete sequence analysis of type IV procollagenase. Peptide inhibitors were synthesized which correspond to cysteine repeat regions and histidine containing regions; the mechanism of action of these peptides involves inhibition of binding of the enzyme to the substrate. Peptide inhibitors were synthesized which correspond to the peptide cleaved off during activation, and constitute a novel class of metalproteinase inhibitors. These inhibitors are members of a series of peptides which contain the core amino acid sequence RKPRC or analogs thereof. The cysteine residue is required for activity. Affinity purified antibodies directed against specific peptides can be used to a) detect any general metalloproteinase enzyme with the sequence in part VAAHE or PRCGNPD, and distinguish it from other known members of the metalloproteinase family, b) block functional domains resulting in the inhibition of enzyme activity, and c) distinguish latent from activated forms of the enzyme.

Granted: 1995-10-24
Abstract: A  semiconductor  laser  device  comprising  a  semiconductor substrate,  a multi-layered double heterostructure having active layers, a pair of cladding layers, a ridged waveguide structure and a current confining structure formed between the semiconductor substrate and the active layer.  With such an arrangement, injected current is narrowed not only on the side above the ridge of the active layer but also on the substrate side of the active layer to improve  the  threshold  current  and  its  current  confinement performance.   When the two lateral trenches of the ridge are embedded with resin layers, the ridge stripe width can be made narrow to improve the threshold current of the device.  When the active layer is realized in a DCC structure having two active layers  and  having  an  intermediary  clad  layer  sandwiched therebetween, the device will show a low threshold current circular beam divergence and stabilized thermal characteristics.

Title: Tee nut
Inventor: NAGAYAMA YUTAKA
IPC: F16B37/14
Filed: 1992-01-30
Granted: 1995-08-15
Abstract: A tee nut is integrally made of a metallic material, comprising a shaft portion and a flange portion, the latter having two pairs of pawls projecting in the direction in which the shaft portion extends, the pawls being disposed radially of the flange portion.  The peripheral edge of the flange portion is formed with projections at positions opposed to each other in a radial direction which is at right angels with the radial direction in which the two pairs of pawls are opposed to each other, the projections extending in the same direction as that in which the pawls extend.  The clearances in guide rails of C-shaped cross-section constituting a feed track are substantially decreased in size by the presence of the pointed projections producing a decreased frictional resistance, and the overlapping of the flange portions due to the rise of the flange portions in the guide rails is prevented, thus ensuring smooth movement of the tee nut along the feed track.
