Title: Woodworking Press
Inventor: TARBELL RUSSELL JOHN
IPC: B66F3/08
Filed: 1996-08-06
Abstract: A woodworking press for effecting a mating of jointed boards. The instant invention is an elongated pressing/ jacking device which includes, at one end, an anchor piece, at the other end a reversible head for contact of a workpiece and a central turnbuckle structure connecting the anchor and the head. The anchor is adapted for nailing to a substrate and has a feature to enhance prying the anchor from the substrate. The turnbuckle device is conventional, but is enhanced by use of a transfixed, shuttling handle. The head is unique in that it is designed having multiple edges which may be brought into mating contact with wood joint structures of varying morphology. Through use of a simple, yet elegant, connection mechanism, the head may be alternately positioned so as to present different mating configurations to the workpiece.

Title: Transdermal drug delivery by electroincorporation of microcarriers
Inventor: HOFMANN GUNTER A
IPC: A61N1/30
Filed: 1994-12-13
Abstract: A method of transdermal molecular delivery comprises the steps of encapsulating molecules to be delivered into microbubbles, contacting a selected area of a tissue surface with a solution of the microbubbles, and applying a pulsed electric field of sufficient amplitude to induce dielectric breakdown of the stratum corneum and to induce transport of the molecules through the pores in the stratum corneum into the underlying tissue to enable diffusion of molecules into the tissue. In one embodiment the microbubbles are too large to pass through the pores in the SC and are fused to the surface where pores form passages from the microbubble through the SC. In another embodiment, the microbubbles are small enough to pass through the pores in the SC and pass through the pores and broken down by enzymes in the tissue.

Patent CA-2189303-A1 (CA)
Inventor: SMITH ARTHUR RAMSDEN
IPC: F01K23/06
Filed: 1996-10-31
Abstract: An integrated gas turbine/air separation system is operated at or below full system load by feeding the air separation unit with air from a dedicated air feed compressor and optionally with extracted air from the gas turbine air compressor.  When the gas turbine air compressor discharge drops below a selected pressure at part load conditions, the flow of extracted air to the air separation unit is discontinued and the air separation unit operates at constant pressure supplied only by the air feed compressor.  This mode of operation is particularly useful in an integrated gasification combined cycle (IGCC) power generation system and allows the design of the oxygen and nitrogen product compressors such that the compressors operate at high efficiency during full load IGCC operation.

Patent CA-2201085-A1 (CA)
Inventor: TSUDA HIROKI
IPC: H04W84/06
Filed: 1997-03-26
Abstract: Station mobile comprenant un détecteur de puissance, un circuit de mesure des valeurs moyennes et un détecteur d'évanouissement de signal. Le détecteur de puissance mesure la puissance d'un signal reçu. Le circuit de mesure des valeurs moyennes établit la valeur moyenne de la puissance du signal de réception mesurée par le détecteur de puissance. Le détecteur d'évanouissement de signal détecte l'évanouissement de la puissance du signal de réception en utilisant la valeur moyenne de cette puissance. Lorsque l'évanouissement du signal de réception est détecté pendant qu'une demande d'appel ou une réponse à un appel est transmise, après recouvrement de la puissance du signal de réception, un circuit de commande de la station mobile retransmet la demande d'appel ou la réponse à l'appel. Lorsque l'évanouissement du signal de réception est détecté juste avant la transmission d'une demande d'appel ou d'une réponse à un appel, un circuit de commande de la station mobile interrompt la transmission de la demande d'appel ou de la réponse à l'appel. Après recouvrement de la puissance du signal de réception, le circuit de commande de la station mobile transmet la demande d'appel ou la réponse à l'appel.

Patent CA-2203893-A1 (CA)
Title: Sleeved packaging method
Inventor: WILKEY ANDREW WILLIAM
IPC: B65B17/02
Filed: 1995-10-25
Abstract: Two or more products e.g. (10, 12) are packaged together by wrapping a wrapper of heat-shrinkable plastics sheet material around them, the wrapper having contact adhesive on one or more surface areas e.g. (21): the wrapper is applied so that its opposite edges either overlap and bond together via the contact adhesive, or both bond to one of the products e.g. (12). Optionally the wrapper is of heat-shrinkable plastics material, in which case heat may then be applied so as to shrink the wrapper so that the products become more firmly held together. It is an easy matter for the consumer to remove the wrapper, by peeling apart the areas which are held by the contact adhesive. Instead of being positioned side-by-side, the products may be stacked one on top of the other, and the wrapper applied around the two products where they meet.

Inventor: PARK IN JAE
IPC: H04L27/00
Filed: 1997-09-18
Abstract: The transmission of information is getting important in the recent information-intensive society.   The conventional digital modulation system for mobile communication is a phase shift keying (PSK) system or a quadrature PSK system.          However, under the recent communication environment where frequency resource is limited, the modulation method described above connot satisfy the requirements of high speed transmission and mass information transmission.   Moreover, it is necessary to develope a better modulation system in terms of high bandwidth efficiency and constant envelope characteristic in the non-linear communication system, such as satellite communications.   Accordingly, the present invention is directed to solve the bandwidth efficiency problem resulted from the lack of frequency resource, implementing the constant envelope characteristic for the non-linear communication system, based on 16-QAM (Quadrature Amplitude Modulation) system.    The present invention limits the data, which will be modulated and transmitted, to 3-bit and adds a parity bit to make them have the constant envelope in the 16-QAM system, which modulates data to be transmitted in the unit of 4-bit.          And the data value of the parity bit is decided to satisfy the condition of  constant envelope in accordance with the QAM signals.

Title: Installing a pipe in an existing pipeline
Inventor: DICKINSON DUDLEY TREVOR
IPC: F16L55/12
Filed: 1996-04-03
Abstract: A seal (210) is fed into an existing pipe (12) to a position beyond the end (10) of the pipe. Manipulation of an elongate assembly (200) breaks the filaments (212) allowing the seal (210) to deploy. The assembly (200) is retracted to engage the seal body (226) with the end (10) of the pipe (12). A  plastic pipe (230) is advanced into the pipe (12) until a steel nose-piece (232) carried by the leading end of the plastic pipe (230) engages the frusto-conical end (224) of the seal assembly and bridges electrical contacts (226) to indicate that the plastic pipe (230) is correctly positioned. The space (238) between the existing pipe (12) and the plastic pipe (230) is filled with sealant (240). The elongate assembly (200) is withdrawn.

Abstract: Un régulateur (10) de débit en fonction de la demande règle le débit d'eau qui alimente un immeuble sur la base d'un approvisionnement en eau variable et de pressions de demande d'eau variables. Lorsque la demande en eau augmente en aval du régulateur de débit, la pression de l'eau diminue en aval du robinet à piston (200) et le piston (201) d'un robinet à piston (200) se déplace vers l'aval. Ce mouvement permet d'exposer un nombre accru de trous d'accès (320) au débit d'eau, et par conséquent d'augmenter le débit d'eau lorsque la demande d'eau augmente. Un robinet de purge réglable (500) permet, en modifiant le mouvement du piston (201), de contrôler les caractéristiques de débit du régulateur (10).
