Title: Missing bearing detector
Inventor: OLSCHEFSKI ROBERT
IPC: G07C3/00
Filed: 1987-06-18
Abstract: A missing bearing detector for an internal combustion engine (10) in which the engine, at an early stage in the assembly process, is tested on the assembly line by rotating the crankshaft (72) to move the piston assemblies through their reciprocal cycles; microphones (40, 42) are placed near the engine to pick up high intensity noises indicative of missing bearing parts; and encoder signals are generated for transmission to a comparator (23) where they are compared to the noise signals generated by the microphones (40, 42) to indicate whether a bearing is missing and to indicate the particular piston assembly in which the bearing is missing. The detector also functions to distinguish between upper and lower bearing shell halves by noting whether relatively low level (54) or relatively high level (58) thresholds are violated by the fault signal (62, 64) and also distinguishes between pairs of piston assemblies moving in phased relationship by providing a pair of microphones (40, 42) axially spaced along the engine (10) to thereby generate relatively high intensity and relatively low intensity fault signals depending upon the distance of the respective microphone (40, 42) from the faulty piston assembly.

Abstract: On peut démouler un article moulé non déformable (30) en plastique généralement rigide, tel qu'un couvercle de fermeture d'un récipient en plastique pour boissons gazéifiées, d'une partie centrale interne (64) d'un moule (60) présentant une gorge, en façonnant la partie annulaire de démoulage (66) du moule de telle sorte qu'elle présente une surface de coinçage supérieure coudée (86). L'article moulé est façonné de manière à présenter une face coudée correspondante (50), le résultat étant que, durant l'avance de la partie annulaire de démoulage par rapport à la partie centrale interne, la surface de coinçage coudée de la partie annulaire de démoulage permet au segment (42) de l'article logé au départ dans la gorge (90) de la partie centrale interne d'être décoincé de la gorge, l'article non déformable généralement rigide pouvant ainsi être retiré du moule.

Patent WO-8809762-A1 (WO)
Inventor: LANDSMAN ROBERT M
IPC: B65H35/04
Filed: 1988-06-02
Abstract: Le mécanisme (10) de transport de films est destiné à l'extraction du film (16, 24) d'une ou de plusieurs cassettes (12, 14) et permet de couper une feuille de film et de stocker la feuille dans un appareil de stockage temporaire (42) jusqu'au moment où la feuille doit être chargée. Le mécanisme (10) comprend un guide de film (20) qui se déplace entre deux positions pour modifier la longueur de cheminement du film passant au-dessus du guide. Pendant l'opération d'extraction du film (16, 14), ce dernier exerce une force sur le guide (20) ce qui provoque le déplacement du guide (20). Lorsque le film (16, 24) est coupé, la force du guide de film (20) disparaît pour permettre au guide (20) de revenir à sa position de repos dans le chemin du film (16, 24) de manière à accroître la longueur de cheminement et par conséquent rétracter le film (16, 24) passant au-dessus du guide (20).

Title: Dosage form having reduced abuse potential
Inventor: LEE EUN SOO
IPC: A61P25/30
Filed: 1989-10-23
Abstract: Compositions and dosage forms for administering abusable substances which have a reduced potential for abuse without diminishing the therapeutic or beneficial effects of the abusable substance. Topical compositions (1) contain: (a) the abusable substance (3) in a form which is permeable to the skin or mucosa; and (b) an antagonist (4) for the abusable substance in a form that is impermeable to the skin or mucosa to which the composition is to be applied. Controlled release dosage forms (10) which release the abusable substance (13) from a drug reservoir composition (11) confined behind a release rate controlling barrier (16) contain the abusable substance (13) in a form that is releasable from the dosage form (10) and the antagonist (14) in a form that is not releasable from the dosage form. This invention permits an abusable substance to be administered by the prescribed route at a substantially full potency, while reducing the abuse potential of the compositions and dosage forms via other routes of administration. Preferred transdermal forms of this invention utilize fentanyl as the abusable substance and naltrexone as the antagonist.

Inventor: YALVAC E DENIZ
IPC: G01N31/00
Filed: 1992-02-18
Abstract: A chemical analysis method for the determination of a first organic acid in the presence of a second organic acid both of which are in a solution to be analyzed. The first step is to form a pH adjusted solution to be analyzed such that the first acid is predominately in its unionized form and so that the second acid is predominately in its ionized form. The second step is to partition the pH adjusted solution to be analyzed from a receiving solution with a semipermeable membrane. The last step is to determine the concentration of the first acid in the receiving solution so that the concentration of the first acid in the solution to be analyzed can be estimated. Valve (15) is actuated and a predetermined volume of solution to be analyzed is added to the flowing stream of liquid buffer adjusting its pH to that of the buffer and is carried to the inside of the membrane (22). The first acid permeates into the membrane (22) from the pH adjusted solution and then out of the membrane (22) into the flowing receiving solution and is conducted to the detector (25).

Inventor: PURCHIO ANTHONY F
IPC: A61K39/395
Filed: 1992-03-13
Abstract: The present invention relates to the production of large quantities of a novel chimeric TGF-β, termed TGF-β1/β2, by eucaryotic host cells transfected with recombinant DNA vectors containing the TGF-β1/β2 precursor coding sequence controlled by expresson regulatory elements. Simian TGF-β1 cDNA (Sharples et al., 1987, DNA 6:239-244) was modified so that the nucleotides encoding amino acid residue numbers 9-13, 17, 19, 25 and 26 of the mature TGF-β1 sequence were hanged to the nucleotides encoding the corresponding amino acids of the mature TGF-β2 structure. Simian codon usage was maintained. The chimeric TGF-β1/β2 of the invention induces effects on the proliferation of vascular endothelial cells equivalent to those induced by TGF-β1 (see Section 7., et seq.).

Title: System for short-range transmission of signals over the air using a high frequency carrier
Inventor: SCHOTZ LARRY
IPC: H04B1/16
Filed: 1992-08-20
Abstract: A system is provided which transmits either analog or digital data signals over the air. The system includes a transmitter (10) and a receiver (12). The transmitter and receiver are arranged to transmit signals using a carrier signal having a high frequency such as in the range of 902-928 MHz. The transmitter and receiver are configured to provide for the transmission of two channels of stereophonic signals while maintaining high signal-to-noise ratios, good frequency response, and low distorsion. To provide for the proper transmission of signals between transmitter and receiver, these devices include oscillating circuits (40, 102) having ceramic resonators which provide a base frequency which is readily modulated to facilitate proper transmission of either analog or digital signals between the transmitter and receiver. To further improve the transmission capability between the transmitter and receiver both include substantial buffering, isolation and shielding between selected circuit components to prevent unwanted areas of frequency modulation within the transmitter and receiver.

Title: Attaching optical fibers to integrated optic chips
Inventor: HOCKADAY BRUCE D
IPC: G02B6/30
Filed: 1992-10-07
Abstract: A method of attaching an optical fiber to an IOC includes the step of forming an alignment groove in the waveguide surface of the IOC by utilizing a laser ablation system to remove a predetermined portion of the IOC material. Next, a dicing saw or other cutting means is used to cut into the IOC at a depth less than the thickness of the IOC, the cut forming a cut surface which is normal or at an angle with respect to both an optical axis of the waveguide and to an axis of the alignment groove, such step of cutting performing the additional function of optically polishing the cut surface. Next, an optical fiber is disposed within the alignment groove, and the fiber core is optically aligned with the optical axis of the waveguide by translational and rotational positioning of the fiber end face adjacent to the cut surface. The fiber end face is then secured to the cut surface with adhesive or other suitable means, and the fiber is attached to the IOC within the alignment groove with adhesive or other suitable means.
