Title: Closure devices for motor vehicle master cylinders
Inventor: ELLIOTT COLIN
IPC: B60T17/22
Filed: 1997-03-07
Abstract: A closure device for use with a motor vehicle master cylinder has a closure member and a retainer arrangement for securing the closure member on the master cylinder. The retainer arrangement comprises a elongate retainer, a first anchor member for securing one end of the elongate retainer relative to the closure member and a second anchor member adjustably engageable with the elongate member for securing the elongate member to the closure member, with the elongate member extending beneath the master cylinder for retaining the closure member on the master cylinder. To facilitate installation without requiring an installer to reach beneath the master cylinder, the elongate member is made of a material which is sufficiently rigid to be self-supporting in a cantilever condition when gripped at a spacing from a free end thereof, the elongate member being sufficiently flexible to wrap beneath the master cylinder when secured by the anchor members.

Title: An improved air brake hose coupling member having an extended locking lug
Inventor: JOHNSON THEODORE C JR
IPC: B60T17/04
Filed: 1997-03-21
Abstract: A coupling member for detachably connecting together two sections of air brake hose between railroad cars. Each coupling member has a hollow tubular body with one end attached to a section of hose and with an opposite end having an arcuate body portion extending circumferentially about and outwardly of the tubular body, and has an arcuate locking lug with a guide and protection surface followed by a locking surface extending generally axially from the body concentric with and projecting along substantially the entire arcuate body portion. An L-shaped arcuate flange projects outwardly and forwardly from a rear portion of the tubular body and is provided with a lip which engages a similar lip formed on the arcuate locking lug of the other of two coupling members to secure the members in coupled position where the lip projects from only a locking portion of the lug while a guide portion has a smooth surface. An elastomeric gasket is mounted within the bore of the tubular body and forms an airtight seal with a similar gasket mounted on the other coupling member. A finger is pivotally mounted within a radially extending slot formed in an arcuate end body portion of the tubular body. A protective flap is secured over the finger to protect the finger from weather related and environmental hazards, while providing a slit to allow for locking and unlocking motion.

Title: Chain of elastic bands, method and installation for the production of a chain of elastic bands and method and installation for feeding elastic bands from the chain of elastic bands to a handling installation
Inventor: VAN DER DONK CORNELIS HENRICUS
IPC: B29C67/00
Filed: 1995-09-26
Abstract: The present invention relates to a chain of elastic bands (1), comprising at least two elastic bands (3), wherein adjacent elastic bands are joined to one another by means of at least one bridging piece (4). The longitudinal direction (A) of the elastic bands preferably extends transversely to the longitudinal direction (C) of the chain of elastic bands (1). The chain of elastic bands can have been produced from a flat, sheet-like web of elastic material (9), such as rubber, preferably natural rubber, in which essentially oval elastic bands (3) have been formed. The elastic bands have a constant width (B) all round. Adjacent elastic bands are preferably joined to one another by at least two bridging pieces (4), which are preferably each arranged at a transition between the adjacent longitudinal strips (5) and arc-shaped strips (6). The chain of elastic bands according to the invention can be rolled up into a roll or can be folded up to form a harmonica-like stack. Chains of elastic bands of this type can be produced, for example, from rubber which is still in the unvulcanised state or from an elastic plastic.

Abstract: Nous voyons présentement sur le marché des supports de boîtes de papiers mouchoi rs qui recouvrent entièrement lesdites boîtes. Nous pouvons les installer un peu partou t où nous voulons des papiers mouchoirs. Nous voyons surtout de ces supports sous les comp toirs de salles de bain des grands hôtels par exemple. Plusieurs personnes se fabriquent de tels supports et les décorent à leur façon. Dans les voitures, nous les voyons surtout placés sous le tableau de bord. Nous savons et le constatons très bien, que les compagnies fabricantes de boîtes de papiers mouchoirs, dépensent de gros argents pour l'apparence de leurs boîtes de papiers mouchoirs et leur donnent des couleurs pouvant s'harmoniser à différents décors. Dans la présente invention, j'ai tenu compte des couleurs et apparences de ces b oîtes de papiers mouchoirs. Cette invention sert justement à mettre en évidence cesdites boîtes e t à les rendre plus pratiques ou simplistes. Cette invention se trouvera fabriquée de deux faço ns différentes, car d'une façon elle sera murale et s'installera partout dans la maison et l'aut re sera fabriquée différemment pour s'installer surtout dans les voitures.

Title: Spacer for glass blocks
Inventor: CERVENKA BOHUMIR
IPC: E04C1/42
Filed: 1996-04-26
Abstract: A spacer for use in forming a wall of glass blocks which includes a pair of parallel elongated first arms, a pair of parallel elongated second arms, with each of the second arms being perpendicular to a corresponding one of the first arms so as to form a pair of spaced apart crossed arms. An elongated connecting bar interconnects to the crossed arms a plate positioned parallel to each of said crossed arms. A frangible coupling affixes each of the plates to a corresponding one of the crossed arms and an elongated vane element extends out from and across the plates and passes through a notional line through a center of each of the frangible couplings so that a user may grip and twist the vane element so as to impart a torque about the notional line which shears an associated frangible coupling at its joint with an associated one of the crossed arms without imparting any translational force to the spacer.

Title: Personal protection
Inventor: KUESTER STEPHEN MICHAEL
IPC: F24F8/108
Filed: 1996-06-07
Abstract: A transparent canopy (7) covers an infant seated within a baby-buggy for protecting him/her from exposure to ambient-air pollution, and a powered filter-unit (9) blows filtered ambient-air into the top of the compartment (8) between the canopy (7) and the seat-unit (4). The bottom of the compartment (8) is open where a lower, apron portion (16) of the canopy (7) hangs spaced from the seated-infant's legs. Entry of polluted air via the opening is blocked by operating the powered filter-unit (9) to create positive pressure within the compartment (8) so that the filtered air flows downwardly of the infant's face and body; a mesh inset (20) in the canopy (7) gives balanced ventilation and avoids heat build-up. The seat-unit (4) involves a back panel (25) suspended by fabric sections (26-28) within a frame (5). The panel (25) can be unlatched (29) to adapt the seat-unit (4) for use as a carry-cot.

Patent CA-2230453-A1 (CA)
Title: Coating system and its use for producing polyurethane acrylate coatings for laminated sheets
Inventor: WEISS JOSEF
IPC: C08G18/75
Filed: 1997-06-19
Abstract: A coating system consists of a resin component, a hardening component and additives. The resin component contains (meth)acrylic double bonds and at least two reactive hydroxyl groups, and the hardening component consists of a multifunctional, at least bifunctional isocyanate. The proportions of resin and hardening component in the coating system are stoichiometric. The coating system is suitable for producing laminated sheets with a surface layer of progressively hardened polyurethane acrylate. During a first hardening stage, the free hydroxyl groups of the resin component cross-link with the isocyanate groups of the hardening component, forming an urethane acrylate prepolymer which contains (meth)acrylic double bonds. In the second hardening stage, the (meth)acrylic double bonds continue to cross-link, forming the urethane acrylic polymer coating of the sheet surface. This progressive cross-linking reaction may be controlled by altering the reaction parameters, such as pressure, temperature, choice of additives and chemical constitution of the hardening component.
