Title: Rotation transmitting mechanism and automotive transfer using the same
Inventor: MIMURA KENJI
IPC: B60K17/348
Filed: 1997-08-01
Abstract: The present invention provides a rotation transmitting mechanism capable of transmitting a power in a constantly stabilized manner irrespective of a low speed rotation or a high speed rotation, and a transfer for automobiles using the rotation transmitting mechanism.   In the present invention, when a rotational difference occurs between the casing 1 and the shaft 3, the rollers are allowed to roll while being in contact with pressure plates 5 on one hand which rotate together with the casing 1 and in contact with pressure plates 6 on the other which rotate together with the shaft 3, while simultaneously the pressure rotor 9 rotates within the viscous fluid 6 so that the pressure of the viscous fluid 6 presses the piston disk 4 toward the rollers 7.   This will result in a generation of a frictional force corresponding to a pressing force of the piston disk between the rollers 7 and the pressure plates 5, 6, the pressing force serving as a resistance for the transmission of the power.  At that time,  the rollers generate a sliding friction in rolling motion, thus ensuring at all times a stable frictional force by a dynamic friction   without generating any static frictional force.

Inventor: MICKAEL MEDHAT W
IPC: G01V5/12
Filed: 1997-08-01
Abstract: A method of measuring the density of an earth formation penetrated by a wellbore. The method includes irradiating the earth formation with gamma rays from a source, detecting Compton scattered gamma rays at a plurality of locations spaced apart from the source along the wellbore, calculating an apparent density of the formation from the detected gamma counting rate at each of the locations, calculating differences in apparent density between pairs of the apparent densities, calculating a correction for the apparent density from a distal one of the locations by scaling the differences in apparent density according to an empirical relationship, and calculating the density by combining the correction with the apparent density from the distal one of the locations. In a preferred embodiment, the empirical relationship is determined by measuring the apparent densities and differences in apparent density at a plurality of known values of density of the formation and a plurality of values of density and thickness of a medium interposed between the formation, and the source and the spaced apart locations. Scaling coefficients are determined by minimizing the value of an error function representing the difference between the known value of the density and the density determined according to the empirical relationship.

Title: Crimper assembly for sealing overlapping portions of a sheet of packaging material
Inventor: SMITH LARRY E
IPC: B65B9/08
Filed: 1997-09-08
Abstract: A crimper assembly includes upper and lower crimper bars which are rotated relative to a sheet of packaging material. A pair of upper crimpers are secured to opposite sides of the upper crimper bar, while a pair of lower crimpers are secured to opposite sides of the lower crimper bars. Each of the upper crimpers includes a metallic base having an outwardly facing portion with an undulating cross sectional shape. A slot is formed in the outwardly facing portion of the upper crimper, and a cutting blade is retained therein. In a first embodiment, an insert is secured to the base of each of the upper crimpers.  The insert includes a rigid shank having a lip portion extending therefrom.  Portions of the outer surface of the shank are covered by a layer of a relatively resilient material. The layer is formed from a material which is suitable for compressing overlapping portions of the folded sheet of packaging material to form an intermeshing seal pattern. The outwardly facing portion of the layer of resilient material includes a longitudinally extending, outwardly facing resilient crimping surface with an undulating cross sectional shape. The lower crimpers are formed in a similar manner, except that an anvil is retained within the slot. During operation, the crimpers are rotated such that the folded sheet of packaging material is compressed between the downwardly facing undulating surface of the upper resilient layer and the upwardly facing undulating surface of the lower base. As a result, the overlapping layers which make up the folded sheet of packaging material are sealed together to form a trailing edge seal for a packaged article. The cutting blade and anvil cooperate to cut the sealed packaging material into individual units.

Abstract: Pertactin (formerly 69 kDa protein) is recovered in stable  biologically  pure  form  having  no  detectable adenylate cyclase activity from fermentation broth from the fermentation of Bordetella pertussis as well as from the cells.  The broth is processed to selectively remove pertussis  toxin  (PT)  and  filamentous  haemagglutinin (FHA),   the  pertactin  is  precipitated  by  ammonium sulphate and the precipitate is dissolved in buffer at pH  6.0  to  8.5,  the  solution  then  is  passed  through hydroxyapatite  and  Q-Sepharose chromatograph  columns before final ultrafiltration.  Cells are extracted with urea and the extract ultrafiltered and diafiltered.  The pertactin  is  precipitated  from  the  extract  and  the precipitate processed as above.   In a variation,  the broth is contacted with ammonium sulphate to precipitate pertactin, PT and FHA, the precipitate is dissolved and the PT and FHA selectively removed, before the solution is passed to the chromatograph columns.

Abstract: A hockey game cage consisting of two surfaces sloped towards the middle so hockey pucks will slide down or balls will roll into a bottom guide which flips the pucks over on their edges allowing them to roll. The pucks or balls roll down the bottom guide which is sloped towards the front of the game and are carried up a guide by a belt which has forks protruding from it. The forks carry the puck up an elevation guide and drop them into a top guide which is sloped to the back. The pucks or balls roll down the top guide back to the shooting surface. The top guide has a crossover to allow the pucks or balls to either go on a left or right shooting surface. The pucks or balls are shot at targets which are placed in a hockey net at the front end of the unit. As the pucks or balls pass through the targets they will activate switches that will detect their presence and calculate the appropriate score.

Abstract: The contact error of a contact section which is brought into contact with an IC card is detected reliably. The level of a reset signal which is supplied to a reset terminal (RST) of an integrated circuit (21) mounted on the IC card (20) through a contact section (11) is controlled to be low and, also, the level of a clock signal which is supplied to a clock terminal (CLK) of the integrated circuit (21) through the contact section (11) is controlled to be low. After that, power for the integrated circuit (21) is supplied to a power supply terminal (Vcc) of the integrated circuit (21) through the contact section (11). At that time, the voltage which is outputted from an I/O  terminal (I/O) of the integrated circuit (21) through the contact section (11) is compared with a predetermined reference level by a comparator (16). When the voltage is lower than the predetermined reference level, it is judged to be contact error of the contact section.

Abstract: A method of identifying a peptide which permits or facilitates the transport of an active agent through a human or animal tissue. A predetermined amount of phage from a random phage library or preselected phage library is plated onto or brought into contact with a first side, preferably the apical side, of a tissue sample or polarized tissue cell culture. At a predetermined time, the phage which is transported to a second side of the tissue opposite the first side, preferably the basolateral side, is harvested to selected transported phage. This modified phage is amplified in a host. This cycle of events is repeated (using the transported phage produced in the most recent cycle) a predetermined number of times to obtain a selected phage library containing phage which can be transported from the first side to the second side. Lastly, the identity of at least one peptide coded by phage in the selected phage library is determined to identify a peptide which permits or facilitates the transport of an active agent through a human or animal tissue.
