Patent CA-2133668-A1 (CA)
Inventor: CHEN QING S
IPC: A61N1/36
Filed: 1994-10-05
Abstract: The vision fatigue curing device I invented generates a preset frequency of photo pulses as well as a preset frequency and amplitude of electrical pulses to massage and stimulate human vision's nerve system and nerve tips in muscles surrounding our eyes so as to yield the following treatment results: (1) Improve circulation, blood supplies within the related blood vessels. (2) Alternatively excite and relax eye muscle to recover its refraction regulation function and as a treatment to vision fatigues. (3) Prolonged usage can stimulate our vision system to regulate the depth of the front room of the eye balls, shorten the diameter of the eyeballs. i.e. improve vision, recovery from myopia or presbyopia. The said effects is achieved by (1) red light emitted by the device, and (2) micro vibrations through electrode contacts attached to outer skin and acupoints around the eyes. The advantages of the invented device are its high portability, low cost, easy to use, and is most effective for computer operators, drivers, especially for young children with false myopia.

Abstract: The invention described herein pertains generally to an applicator for use in transferring a grip-enhancing substance onto a piece of equipment. The applicator is essentially tubular in nature and has a longitudinal slit along the length of the applicator thereby permitting a piece of equipment to be inserted thereto. The applicator has an absorbent inner component which is adhesively secured to the foamed exterior component, the inner layer having the grip-enhancing substance applied thereto. Through the application of a force, typically a squeezing action, onto the exterior of the applicator, a controllable amount of the grip-enhancingsubstance is transferred from the inner component to the inserted piece of equipment. In one embodiment, the grip-enhancing substance is a replacement for pine tar, and is a synthetic polymer blend, the degree of tack of the product being both a function of the composition of the polymer(s) used in the composition, and when the composition is a mixture of two or more polymers, by the ratio of the two components.

Filed: 1996-05-30
Abstract: A new Multi Stage Flash (MSF) distillation system of enhanced flashing, brine reheat and superimposed Multi Effect (ME) distillation system (named herein as: Combined MSF-ME System With Brine Reheat) is disclosed. The invented system has special features designed to increase the distillation unit capacity and production rate, and improve its performance. The invented system uses a combination of: i) the up-to-date (proven design) MSF system as a base system with different methods to improve the flash chamber effectiveness (non-equilibrium factor) and flashing evaporation rate; ii) increases the MSF system flashing range through brine reheat, i.e. supply (all or part of) the brine with additional (external) heat in brine reheaters (located after the brine heater and/or within the flash chambers), and; iii) superimposes the ME distillation concept and system on the MSF base system. The invented system utilizes the mainfeatures and advantages of both MSF and ME systems simultaneously, and operates within the existing (proven design) system's constraints and limitations. The invented system allows, also, for the possibility of utilizing waste heat as the externalheat-source for brine reheat. The invented system, therefore, presents a break-through for the future generation of saline water desalination systems of higher capacity, better performance and lower water production costs.
