Title: Method and arrangement for data transmission
Inventor: ZIJDERHAND FRANS
IPC: H04W56/00
Filed: 1992-07-07
Granted: 2001-01-23
Abstract: A communication protocol is proposed, to be used by a main station and a plurality of mobile sub-stations, while time slots are used in which data packets are transmitted. A  substation that has a message to be sent to the main station first transmits a request-for-access data packet to the main station.      If the sub-station knows its own position as well as that of the main station, the sub-station applies an advancement of time to the request-for-access data packet, so that this may be longer and contain more information, such as a self-selected recognition code and/or information relating to the length of the message to be sent. The main station measures the instant at which the request-for-access data packet is received relative to the time slot distribution and sends a correction of the advancement of time to the sub-station. After a send permission has been granted, the data packets are transmitted with a length essentially corresponding to that of the time slots, so that more information can be transmitted per data packet.

Title: Odorant and cosmetic dispensing articles
Inventor: BANKO ELIZABETH M
IPC: A45D40/00
Filed: 1992-08-31
Granted: 1997-11-18
Abstract: Described is a dispensing unit of a volatilizable substance capable of visible determiation of its extent of use.  The unit has a variably located centroid initially positioned proximate the geometric center point of the unit with the centroid moving downward when the unit is in use.  As the volatilizable substance evaporates, a weight eccentrically located in the same place as the volatilizable substance angularly rotates about the "z" axis leaving its upper position and finally coming to rest at a lower position when the volatilizable material is used up.  At least the final position is rendered visibly detectable by means of a simple sighting mechanism.     Also described are multi-layer, multi-functional volatilizable substance delivery articles.  The articles are constructed in order to deliver, in sequentially-timed fashion, to the environment surrounding the article (e.g., atmosphere, or body of water) different fish feed attractants, repellents, combinations thereof, perfumes having different aroma profiles, insect repellents which repel different insects...during the day time hours and during the night time hours, air freshener-insect repellent combinations, perfume-air freshener combinations and the like.  The article can be constructed where one of the layers is a gel layer and the matrix layer adjacent thereto is composed of perfume-containing particles which emit a fragrance in a sustained release fashion.     Also described is a stick shave formulation and article employing said formulation.  The stick shave formulation contains a triethanolamine stearate soap formed in situ with from 1-10% of a nonionic wetting agent; from 1-15% of a silicone copolymer; from 0.1-1% of a polyoxyethylene polymer slip agent; from 1-30% of a synthetic detergent; from 2-10% of a whitening agent; and 5-20% of emollient moisturizers and hair lubricants.

Title: Improved method and apparatus for sequentially stretching zero strain stretch laminate web to impart elasticity thereto without rupturing the web
Inventor: WEBER GERALD MARTIN
IPC: B29C55/18
Filed: 1992-01-28
Granted: 1995-10-03
Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch lami-nate webs to impart elasticity thereto in the direc-tion of stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate mate-rial (1) is formed of at least two plies (4a, 5, 6) of material which are either intermittently or substan-tially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condi-tion. One of the plies (4a) is stretchable and elas-tomeric, while the second ply (5, 6) is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration. This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretch-ing. In a particularly preferred embodiment of the present invention, the mechanical stretching opera-tion is carried out by passing said laminate web between multiple pairs of meshing corrugated rolls (21, 25, 27), each pair of rolls exhibiting a greater degree of meshing than the preceding pair, to sequentially stretch said web in stages. Sequentially stretching the web in the foregoing manner minimizes damage to the web.

Title: Blood pack labels
Inventor: LEUENBERGER MARK
IPC: A61J1/14
Filed: 1993-02-09
Granted: 2006-04-18
Abstract: A label (12) for a blood pack (10) comprising a microporous plastic film including a matrix of interconnected pores for allowing gas to flow into and out of the blood pack (10) through a labeled area. The pores allow ink to be absorbed at least on an outer surface of the label (12) allowing the label (12) to be printed and/ or written on. The labels of the present invention have breathability with respect to gas that is similar to paper. However, the label (12) is more durable than a paper label in that it can tolerate moisture, abrasion, temperature extremes, dimensional changes, and the like. Accordingly, the labels do not crack or wrinkle as easily as paper labels.
Patent CA-2110457-C (CA)
Inventor: SLICKER JAMES M
IPC: B60W30/18
Filed: 1993-12-01
Granted: 1999-05-25
Abstract: A friction clutch (20) coupling an engine (10) and a gear transmission (30) of a vehicle is controlled by a microprocessor based circuit using logic which defines operating modes according to engine (10) and clutch (20) conditions.  During the time of clutch closure, when the vehicle is starting from rest in a startup or launch mode, the throttle or other engine control signal is restrained from quickly responding to the accelerator pedal  (11).          This  avoids  engine  overspeeding  which  results  from generating high torque before sufficient clutch capacity has been achieved.  The control signal is developed as a function of the pedal position under control of throttle logic which,  in turn,  is dependent on clutch operating modes defined by the clutch logic.  The clutch operating modes  are  four  modes  for  automatic  clutch  operation comprising touch point approach mode which prohibits a throttle signal during initial clutch movement, creep mode or startup mode after touch point (81) occurs, and lockup mode for completing clutch closing when low clutch slip is attained.   A non-automatic mode is entered before the accelerator pedal (11)  is depressed or when engine (10) stall conditions are detected.

Abstract: Access of a user to a resource, such as a telecommunications network, includes storing, in a first call data base, a first set of attributes concerning an ongoing call from a caller.  A second call data base stores a second set of attributes concerning the history of prior calls made by the caller. A rules data base stores rules concerning attributes for determining whether to disconnect the call, block future calls, or take other action.  A determination is made whether data in at least one of the call data bases matches the rules in the rules data base. The call is then disconnected, the next call blocked, or other action is taken, in response to a match between data the call data bases and data in the rules data base.  Preferably, the second call data base is updated in response to matches with the rules data base.
