Patent EP-0178180-A3 (EP)
Title: Metal forming process, apparatus therefor and product thereof
IPC: B21J15/00
Filed: 1985-10-11
Abstract: In a method of forming an integral fastener such as a rivet on a sheet metal component (15) such as part of a clutch plate assembly, the metal sheet is placed between a pair of dies (1, 2) the die (1) having a cavity (3) and the die (2) carrying a plunger (4) co-operating with clearance with the cavity and biased by a spring (7). The die (2) has an annular working face (14) surrounding the plunger (4). As the dies are brought together the plunger first applies a bias force to the portion of the sheet in register with the cavity (3) and then the face (14) acts to compress an annular zone of the sheet surrounding the cavity. The combined effect of the bias force and the compression then causes material to yield in the annular zone and to be displaced from that zone to flow into the die cavity to form a hollow fastener in the clearance between the cavity and the plunger.

Patent EP-0313111-A3 (EP)
Title: Photoprinting with radiation transparent phototools
IPC: H05K3/00
Filed: 1988-02-22
Abstract: A photopolymer layer is used as a radiation transparent in-situ 
phototool in the photographic process of producing solder mask layers on 
printed wiring boards. Various simplification and energy reducing steps are 
introduced with off-contact photoprinting of patterns on liquid photopolymers 
having special characteristics that permit the polymerization of patterned 
outer skin areas partly through the thickness thereof with a controlled 
amount of radiation energy. The skin pattern then becomes an in-situ 
surrogate phototool that permits further polymerization throughout the 
thickness of the layer with controlled quantities of unpatterned radiation 
energy. Photodiscrimination is provided in the further radiation step with the 
surrogate phototool by changes of photosensitivity in the layer transparent to 
radiation rather than by opaque imaging. Thus a first low energy photoflash 
through an off-contact phototool with uncollimated radiation creates on a 
liquid photopolymer surface two contrasting patterned areas of liquid 
polymer, one having a polymerized skin. This can be achieved in a gaseous 
atmosphere that does not react with the polymer surface. The second 
radiation curing step occurs in the presence of a gas such as air on the 
polymer surface, which inhibits polymerization in the presence of radiation 
energy. Thus with controlled radiation energy intensity the polymer layer is 
fully cured through the thickness of the layer in those patterned regions 
having cured skin covered portions without curing the patterned regions 
having a liquid surface.

Title: Monocoque device for dismantling and tightstoring of spent medical syringues
IPC: A61M5/00
Filed: 1988-06-21
Abstract: A prehensile container is provided for demounting and storing used hypodermic needles and/or surgical blades pending their ultimate disposal. The same hand that holds the container can actuate the closure blade by finger force to clear an orifice for passage of a used hypodermic needle. When the end of the syringe to which the needle is affixed abuts the mouthpiece of the orifice, the finger force can be released to hold the needle between the edge of an aperture of the shutter blade and an edge of the orifice, so that the needle can be separated by withdrawal of the syringe with one hand while holding the container with the other. Another exertion of finger force will let the used needle drop into the container and a second release will restore the closed condition of the container. Internal baffles obstruct the exit of stored needles, to prevent an unauthorized person from extracting a needle from the container by opening the access orifice.

Title: Ring shaped local area network
IPC: H04L12/433
Filed: 1988-06-08
Abstract: A ring for circulating multiple packets each 
containing control information and data such as digitised 
audio, includes a monitor system for preventing the 
unwanted accumulation of "full" packets in the ring which 
have already circulated once and have consequently 
fulfilled their function. Each node normally cancels all 
packets it has originated, after one circulation of the 
ring. In case this system breaks down, a monitor node 
sets "on" a monitor flag in all the packets it receives 
and re-transmits and cancels any packets it receives which 
have failed to have been cancelled by the other nodes and 
in which the monitor flag is consequently still "on".
