Patent CA-2123035-A1 (CA)
Inventor: FLANDERS NANCY L
IPC: A61F2/52
Filed: 1994-05-06
Abstract: A kit for the repair of damaged prosthetic devices provides for the economical repair of such prostheses. The kit is directed primarily to the repair of externally worn silicone gel filled breast prostheses, which prostheses are relatively costly and perhaps more vulnerable to damage than other types. The basic member of the kit is a thin, flexible adhesive backed tape of vinyl or other suitable material, which tape may be stored on a backing sheet. The backing sheets may be in the form of a roll, or alternatively several planar sheets may be included in a relatively flat container for persons who may not be able to conveniently carry a bulky roll. Several shapes and sizes of tapes may be included a single kit, and different kits may include different coloring, shading and/or texture in order that the user may most closely approximate the proper coloring, shading and/or texture of the damaged prosthesis. However, each of the repair tapes in a given kit are of like coloring, shading and texture in order that all repair tapes in that given kit will closely approximate the coloring, shading and/or texture of the prosthesis for which the repair kit was made.

IPC: H04L27/22
Filed: 1994-05-17
Abstract: ABSTRACT OF THE DISCLOSURE      An intermediate frequency (IF) converter converts a received signal to an IF signal.  A demodulator demodulates the IF signal to a demodulated signal and detects a phase error.  A frequency error detector detects a frequency error based on the phase error.  A modulated-carrier detector detects a modulated carrier component from the IF signal.   When the modulated carrier component  is  detected,  a  controller  achieves  a  frequency stabilizing operation based on the frequency error.

Title: Skeleton frame green houses and lean-to's enclosed in an envelope of continuous length semi rigid fibreglass
Inventor: RAZ ZOLTAN
IPC: A01G9/14
Filed: 1994-10-26
Abstract: Greenhouses or "lean-to's" for home gardeners are shed forms with gable roofs and vertical walls covered with numerous flat panels of rigid materials (glass, fibre glass or plastic). Frames are of lumber or metal, held together with nails, screws, bolts, or plastic connectors to join the lumber frame parts.     A free standing greenhouse uses the heat of the sun to aid the germination of seeds and speed the growth of plants. If attached to a fixed wall or structure as a "lean-to", it also absorbs the adjacent heat and moderates temperature changes, to increase the efficiency of the greenhouse.
Patent CA-2135368-A1 (CA)
Inventor: KEIGHTLEY JOHN
IPC: G01C15/00
Filed: 1994-11-08
Abstract: An apparatus for projecting a laser beam at an angle to an axis and sweeping the laser beam around the axis around a conical surface having a selected slope is described. The apparatus may be used to aid in the alignment of structures having conical surfaces. The apparatus projects a laser beam along an axis onto a rotating deflection assembly. The deflection assembly contains two mirrors which are optically equivalent to the reflective faces of a pentaprism. Consequently, the angle of the deflected beam is relatively insensitive to vibrations of the deflection assembly. The angle of the deflected beam may be varied by tilting the two mirrors. The alignment of the mirrors is maintained as the mirrors are tilted by a linkage which includes a roller mounted to one of the mirrors which rides on a cam surface coupled to the other mirror. The adjustable mirror-alignment linkage may be used in other optical equipment.

Title: Pair of conveyor worms for rotary positive-displacement pumps
Inventor: MOLLER HEINRICH
IPC: F04C18/08
Filed: 1993-07-03
Abstract: The invention relates to a pair of conveyor worms for rotary positive-displacement pumps, the conveyor worms of which, which are formed as a rotor and counter-rotor, rotate contactlessly in the drilling and the sides at the same speed (worm-drive pump), form loss gaps between them and have the same throat depth and pitch symmetrical flank profiles on each side, made up with respect to their land height of a tooth base beneath the flank profile reversal point (q) and a tooth head thereabove.  To provide an improvement it is proposed that the height of the loss gap (c) determined by the profile in the axial section on the pitch circle can be kept constant for a given rotor diameter (DK) by shifting the flank profile reversal point (q) as a function of a technically attainable rotor rise (H).

IPC: H04J13/16
Filed: 1995-03-28
Abstract: A system and method for optimizing usage of a communications transmission medium. The transmission medium may be sliced into time and frequency domains so as to create time-frequency slices for assignment to users having varying access rates and user-application requirements. Through scheduling of the various speed users within the frequency and time domains, the system and method can efficiently allocate and make use of the available spectrum, thereby accommodating higher rate users requiring greater bandwidths and time slot assignments while still preserving cost-efficient access for lower speed users. Depending on the signal modulation scheme, the time-frequency slices may be allocated on non- contiguous frequency bands. The system and method is also applicable to code-division multiple access (CDMA) techniques by slicing the available code space along time- code domains, frequency-code domains or, in three dimensions, along time-frequency-code domains. Users may be efficiently scheduled based on code space requirements so as to optimize use of the communication medium.

Abstract: A contactless recharging system (10, 100, 200, 300) and method for recharging a battery storage device (12) onboard an electric vehicle (14, 106, 302) has a primary converter station (20, 102, 202, 304) for converting power from a power source (16) into high frequency power at a selected charging rate. The vehicle has a secondary converter (32, 150, 306) for converting high fre-quency power into DC power to charge the battery. The converters are coupled together by a contactless coupling of a conductor loop (30, 104, 308, 420, 430) and a coupling link (25, 25', 110, 205, 310, 310', 310") forming a coaxial winding transformer. The coupled link and loop carry a communication indicating the selected charging rate of the battery. The link has a magnetic core (40; 50; 112; 318, 320, 322 and 324) and a core-mounted conductor (45; 55; 120; 326, 328, 330 and 332) at least partially sur-rounded by the core. The core-mounted conductor selectively at least partially surrounds a portion of the loop to transfer power therebetween. The core-mounted conductor is coupled to one of the converters, and the loop is coupled to the other converter.
