Patent CA-2065858-A1 (CA)
Inventor: WALDMAN HERBERT H
IPC: H04M1/27485
Filed: 1991-07-16
Abstract: 2065858 9202096 PCTABS00010 An abbreviated dialing apparatus (10) especially suitable for cellular/mobile phone (20) use, enabling a user to dial telephone numbers having repetetive digits without directly dialing all of the repetetive digits. The user, by executing a prescribed actuation of a prescribed key, such as the SEND key, can cause the system to complete an incomplete telephone number having repetetive finishing zeroes or other repetetive finishing digits, instead of directly dialing all of the repetetive digits. By determining whether a call is local or long distance, the apparatus determines the number of digits necessary to properly complete a telephone number and completes the number by filling in any missing finishing digits. Alternatively, the user by actuating a finish digit key (17, 18) or a finish zero key (19) can cause the system to similarly fill in any missing finishing digits to complete an incomplete telephone number.

Title: Storage container for sports cards
Inventor: LEMIEUX RICHARD
IPC: B42F17/02
Filed: 1992-04-29
Abstract: ABSTRACT OF THE DISCLOSURE A generally rectangular container for the storage and protection of sports cardshaving a rigid Internal Enclosure which is slidably insertable and completely removable from a rigid External Enclosure. The External Enclosure incorporates two Fingergrip cutouts located to the front and to either side of the External Enclosure to permit grasping the Internal Enclosure for removal. The Internal Enclosure has the capacity to store a plurality of cards and permit random access of such cards by utilizing spaced Bottom Rails which create a gap sufficient for the insertion of a finger or fingers to raise any specific card, or series of cards, up and out of the card stack. The front panel insert to the Internal Enclosure is transparent, thus permitting visibility of the first card in any sequential ordering of cards.

Title: Animal activated feeder
Inventor: HAYNES GRAHAM J
IPC: A01K5/02
Filed: 1991-08-12
Abstract: An animal activated feeder (10) has a base (11) which supports a central cradle (17) for rotation about a central axis. A circular food bowl (40) having a number of receptacles (41) can be positioned on the cradle (17) to rotate with it, or lifted off for cleaning. The base (11) includes a central spring housing (13) having a flat helical torsion spring (14) ("clock spring") which causes rotation of the cradle (17), and therefore the food bowl (40), but rotation is indexed in increments by a pet activated foot pedal (29) which is pivoted to the base and has a finger (28) lying in the path of travel of lugs (25) of a first group which project from the cradle (17). Indexing is limited to feed one receptacle (41) at a time, preventing spinning of the food bowl, by a second group of lugs (24) projecting from the cradle and when the foot pedal (29) is depressed, the finger (28) moves from the path of travel of the first group of lugs (25) and into the path of travel of the lugs (24) of the second group.

Title: Covalent angiogenin/rnase hybrids
Inventor: VALLEE BERT L
IPC: C07K19/00
Filed: 1991-01-07
Abstract: Regional mutagenesis of a gene for angiogenin to produce DNA  sequences encoding mutant proteins having increased angiogenic activity are disclosed. Expression vectors containing these sequences are introduced into host cells and direct the production of mutant angiogenic proteins with markedly increased angiogenic activity.  Replacement of amino acids in a region at or corresponding to residues 8-22 of angiogenin, with other amino acids, in particular, with amino acids corresponding to residues 7-21 of RNase, unexpectedly yields a mutant angiogenin/RNase hybrid protein with 10-fold increased angiogenic potency in the chorioallantoic membrane assay. Other in vivo and in vitro angiogenin-related activities are altered in the mutant hybrid protein. Mutant angiogenin/RNase hybrid proteins according to the present invention are useful therapeutic compositions to promote the development of a hemovascular network in a mammal or to promote wound healing, in particular, healing of torn or traumatized fibrocartilage material.

Title: Method of disposing of organic and inorganic substances and a plant for carrying out the method
Inventor: STEINS JOHANNES
IPC: C10B49/14
Filed: 1992-10-23
Abstract: Abstract of the Disclosure:      In a method of disposing of organic and inorganic substances, the substances are gasified and decomposed in and/or above a liquid bath of a metal alloy under negative pressure, off-gases forming are seized, collected and purified and separated.    To prevent the formation of health-endangering emissions, such as dioxans and furans, and to recover pure starting materials for the production of organic substances, the substances are charged under negative pressure into an induction furnace containing a melt (18) of an iron alloy, in particular a steel melt, and are decomposed in the latter at liquid steel temperature, whereby the entry of gaseous O2 is avoided.    This is also the case at the production of steel from scrap interspersed with organic substances.    To recover pure starting materials from inorganic dusts, the latter are charged into a negative pressure induction furnace containing an iron melt together with suitable additives and are decomposed in that furnace at liquid steel temperature and are transferred to the starting materials.

Title: Flexible blade coating arrangement and method with compound blade loading
Inventor: ALHEID ROBERT J
IPC: D21H23/60
Filed: 1991-04-22
Abstract: Method and apparatus for applying a liquid film of controlled thickness to a paper web (51). The apparatus is in the form of a flexible blade coater having a flexible blade (60) fixed at one end (61) and bearing against a backing roll (50) (with interposed web) at a free end (62). The blade (60) has independent loading means, preferably pneumatic. An intermediate loading means (63) applies a first load intermediate the fixed and free ends (61, 62) which serves primarily and substantially independently to establish blade geometry or tip slope. A second loading means (65) positioned near the free end (62) of the blade (60) primarily and substantially independently establishes tip load for a given geometry established by the first loading means (63). The compound loading arrangement allows a wider range of finer control of coating film thickness.

Inventor: PRINCE PAUL R
IPC: A61M1/30
Filed: 1991-07-22
Abstract: A method and system for adaptively controlled withdrawal/infusion of a fluid, such as blood, to or from a fluid source, such as a blood vessel. An adaptive flow rate limit is established and periodically adjusted during the course of withdrawal/infusion so as to maximize and optimize the withdrawal/infusion rate while, at the same time, providing for rapid corrective adjustments in flow rate responsive to early indications of flow disruption, such as occlusion or collapse of the blood vessel during blood withdrawal. The method and system of the invention is particularly applicable to automated apheresis systems.

Title: Vibration damping device for hammers
Inventor: VAUGHAN HOWARD A JR
IPC: B25D1/04
Filed: 1993-02-19
Abstract: In a claw-type hammer, a shock-absorbing device is provided which includes an elongate elastic band or cord which captured within grooves of a hickory plug in regions which abut against internal surfaces of a socket into which the plug is press-fit.   The plug is dimension and configurated in relation to the socket in the hammer head to provide at least some degrees of freedom of movement of portions of the elastic cord so that the elastic portions can vibrate or oscillate substantially independently of the natural oscillatory vibrations of the hammer head caused by impact. The tendency of the elastic cords is to at least to partially cancel or neutralize and, therefore, dampen the natural vibrations of the hammer head.
