Title: Evaporative water cooler - has heat exchanger connected to upstream water spray nozzles in air passage
IPC: F28D5/00
Filed: 1974-05-10
Abstract: The cooler has a passage into which atmospheric air flows at one end and out at the other, while water is sprayed into the passage under pressure near the intake end in the form of a large number of divergent jets, with a sump and pump collecting the spray water. A heat exchanger is connected directly to the spray nozzles and mounted in the passage downstream of them. Its inlet is supplied with water to be cooled, and the collector sump is mounted downstream of it. A static baffle in the form of a grille, cyclone etc, can be mounted upstream or downstream of the heat exchanger, to reduce the vapour loss from the spray water.

Title: Hollow filaments produced by embossed rollers from synthetic films - for bulky yarns, possibly inflated by air, sheathed wires, etc.
IPC: B29C43/00
Filed: 1975-05-07
Abstract: Threads are produced from synthetic films of a material which when suitably stretched in one direction and tendered under controlled conditions in a direction transverse to the first, divide into filaments with a high degree of tensile strength in the direction of stretch, by feeding at >=2 films through the nip of two bowls, the surfaces of which have a series of circular grooves with ridges between them. The grooves of the two bowls are accurately in register and the ridges are machined so that only the crests of their centre sections come into contact. The bowls are heated to a temperature at which the layers compressed by the ridges fuse together and the films form the enclosing surfaces of threads which are at least partly hollow and are attached to their neighbours by thin single thickness fibres or are separated completely. Two films only may be used to form a completely hollow thread, or, by using three films, a hollow thread with an internal dividing wall may be produced. New and improved products may thus be obtd. from standard matls. at higher rates or prodn.

Title: Shock absorber for vehicle bumper - with energy absorbed by friction between polyacetal and polyphenylene oxide surfaces
IPC: B60R19/26
Filed: 1975-11-26
Abstract: In a shock absorber for mounting between the chassis and the bumper of a vehicle, the shock is transmitted through a movable device which slides through an opening into an elongated housing and is opposed by a thrust deviced fixed in the housing. Fixed and movable elements are attached to the housing and the movable device, presenting surfaces with a significant mutual coefft. of friction in extended transverse contact through interlocking. The movable device is attached to the movable elements so that as soon as it moves into the housing the thrust device causes the frictional elements to move relatively. The indentations may be tooth-like corrugations with inclined sides formed in a transverse wheel rim(arc). The fixed elements may be of polyacetal and the movable elements of poly(phenylene oxide). The device is capable of resisting collisions at up to 8 km/hr. and the friction elements allow high initial energy absorption decreasing to a uniform level.
