Title: Light-weight metal piston
IPC: F02F3/04
Filed: 1986-07-29
Abstract: Light-metal piston for combustion engines, having a sleeve-like insert embedded therein and controlling its heat expansion and being formed of a metal of smaller heat expansion coefficient than the piston base material. The insert is arranged in the solid material of the piston crown and extends around the entire piston periphery. Behind the insert, the piston base material is self-contracted to form a gap delimited by the insert on one side. On at least one edge or one side, the insert is not covered by piston base material, i.e. it extends up to the piston surface, this occurring however only in certain segments and not along the entire piston periphery. In the other segments, the insert lies beneath the piston surface and is thus covered by piston base material. To the extent that the insert is exposed on the piston end face, it is provided with an edge zone covering the depth of the self-contraction gap.

Patent EP-0238414-A3 (EP)
IPC: B41N1/24
Filed: 1987-03-18
Abstract: An improved polyester mesh for screen printing is given. 
The polyester mesh is composed of polyester fibers having conca­
vities and protrusions having a diameter of 0.01 to 0.1 µm in a 
density of at least 200 per µm² of the surface area thereof. A more 
preferred polyester mesh for screen printing has finely dispersed 
concavities and protrusions having a depth or height not exceeding 
0.05 µm. Such a polyester mesh is obtained by subjecting a base 
polyester mesh to a treatment with low-temperature plasma in an 
atmosphere of a non-oxidizing inorganic gas. An improvement for 
printing screens is proposed in which a surface active agent is ad­
ded to the photosensitive resin.

Title: Method of manufacturing a building element in the shape of a hollow brick, concrete block or the like, and building element made according to this method
IPC: E04C1/40
Filed: 1988-07-29
Abstract: New building elements for building constructions made of brick or concrete hollow blocks, the cavities in the bricks or blocks being filled with Styrofoam (polystyrene and the like). To manufacture these building elements, the hollow bricks are lined up on a perforated silicone sheet with their cavities vertical. Dull-edged polystyrene particles are poured in from above. A perforated sheet of silicone plastic is then likewise laid on top. Steam under pressure or another source of heat is then applied, as a result of which the polystyrene particles expand (foam) and thus fill all the cavities. Insulating but at the same time strong building elements are thus obtained in a simple, inexpensive manner and the buildings produced therefrom do not need to be insulated with a separate layer of insulating material. <IMAGE>
