Granted: 1989-09-12
Abstract: ABSTRACT OF THE DISCLOSURE         An insulating stay is disclosed which comprises a central core having high electrical resistance and high tensile strength;  and a sheath of high electrical resistivity including fins to offer a maximum resistance path to possible surface current loses.  The central core is made of resin reinforced with long, continuous fibers, advantageously of epoxy resin reinforced with glass fibers.   The sheath is made of a natural or synthetic polymer, and advantageously of EPDM elastomer.   The stay is manufactured by coating the central core with a high viscosity glue having high longitudinal resistivity, then wrapping the glue-covered core in a hollow tube of raw elastomer and placing the assembly in a mold where the fins are formed in the sheath and where the raw elastomer of the tube is polymerized by vulcanization. The stay is intended for bracing electrical installations that need to be isolated and placed at some distance from the ground.

Abstract: The invention relates to a ventilation apparatus which functions according to the principle of regenerative heat absorption. Located in each of two supply and removal ducts positioned close to one another are a fan 2 and a heat absorption cell element 3. The fans 2 have different directions of rotation, so that one duct functions as a removal duct and the other as a supply duct. By reversing the directions of rotation of the fans, the supply duct can be changed into the removal duct and the removal duct can be changed into the supply duct. The outgoing air heats the cells 3 and the incoming air absorbs heat by cooling the cells 3. The supply and removal ducts 1 each have a connection to a horizontally arranged distribution duct 6 via their own distribution element 4. The distribution chamber 5 is separated from the distribution duct 6 by a damper 7 which allows flow from the ventilated space to the distribution chamber 5. By means of this arrangement, an essentially constant blowing-in rate is achieved through the openings 9 for blowing in incoming air. The apparatus is suitable in particular for ventilation of stall buildings and for regulating both humidity and temperature. <IMAGE>

Date Oct. 20, 1988.A reprographic apparatus has a copyboard for holding a document to be exposed in a flat position in an exposure plane. The copyboard includes a support plate defining the exposure plane with transparent plate arranged above the plate and being pivotally connected therewith along one side edge. A releasable hold-down mechanism locks the glass plate in an operative position in which it holds the document in pressurized contact with the support plate. A movable pressure bar extends in parallel to the pivotally connected side edge of a glass plate, the bar being connected at its ends with side plates, which are displaceably and pivotally connected to a housing of the copyboard. Such an apparatus is known for instance from the EP 0 085 862. After a document has been placed in the exposure plane between the two plates of the reprographic apparatus, a hold-down mechanism (or lock) presses the transparent plate against the document on the support plate, and air still present between the two plates can be extracted by suction in order to achieve a flat exposure position of the document. The lock is provided with an extension to overcome spring forces when unloading an original. A disadvantage of the described system is that it can only handle documents with a size smaller than that of the transparent plate as, otherwise, the hold-down mechanism would damage or destruct the document.

Abstract: A fastener for sliding doors or windows comprises one or more bolt assemblies (8) having sprung loaded bolts with heads (15) mounted in housings set into the stile (7). The fastener also comprises a receiver assembly (9) including a pair of rails (23, 24) having similar aligned key-hole openings (25, 26) respectively. The outer retainer rail (23) is slidable relative to the inner rail by operation of an actuator (27) controlled by a handle assembly (10). When the bolt heads (15) are received in the aligned openings (25, 26) on closing of the stile (7) to the jamb, the handle (29) of the assembly (10) is turned causing the retainer rail (23) to move downwards to trap the heads (15) of the bolt in the narrower parts of each opening (25) in the retainer rail (23). The handle assembly (10) preferably includes a lock to prevent the handle (20) being rotated after locking. The spring loaded bolts provide a "buffer" action and prevent damage to the receiver assembly even if in the fastening position. The bolt assemblies may be mounted on a jamb with the receiver and handle assemblies on the stile.
