Patent DE-3660607-D1 (DE)
Title: Frame for picture material in sheet form
Inventor: JOST JOCHEN
IPC: A47G1/00
Filed: 1986-06-28
Granted: 1988-10-06
Abstract: The holder serves for fixing sheet-like picture material between a back wall (1) and a transparent front pane, which together with the picture material can be exchanged towards the front side. The back wall (1) is designed as one piece with a frame (2) extending around the inserted picture material and the front pane and projecting towards the face side. Frame segments disposed on opposing sides (3, 4) of the frame each support at least one holding attachment (5, 6) and each are cut free by a through-extending opening (12, 13) disposed adjacent the holding attachment, wherein in each case one of said openings is aligned with a holding attachment, exposing an area in the back wall (1) which is larger than the parallel projection of the projecting holding attachment. One (13) of the through-extending openings is shaped in a way such that it can be penetrated by the user with the end of a finger in order to lift out the picture material and front pane for exchanging the picture. The through-extending opening (13) is extended by slots to an extent such that the frame segment (4) disposed adjacent to said opening can be readily deformed for exchanging the picture and is capable of elastically returning to its initial position.

Abstract: This invention is embodied in a mechanical clutch capable of transferring a large force or torque from an input member to an output member by the application of a very small control force or torque. This clutch is capable of performing many non-slipping power engagements per second. When configured as a following mechanical servo, this clutch becomes the crux of a continuously variable transmission (CVT) suitable for automotive use. In such use, mechanical power may be transferred very precisely by a controlling power of much lower level than the power being transmitted through the clutch mechanism. The automotive literature shows many articles which propose 20%-25% fuel efficiency improvement obtained by using a continuously variable transmission (CVT). Today's commercial CVT's have a stepless changing mechanical advantage which is a function of variable pitch diameter ratios, as with wide Vee belts, traction drives. All of these have insufficient power ratings for automotive use. The hydrostatic CVT's operate by the exchange of variable fluid volumes, and have power ratings to drive earth movers. But they suffer from low efficiency and high cost.

Abstract: The present process produces the meso dialkyl 2,5-dihaloadipate from a mixture of the racemic dialkyl 2,5-dihaloadipate and meso 2,5-dihaloadipate. In the disclosed process, a 2,5-dihaloadipoyl halide is formed under conditions which result in the formation of an acidic compound. The 2,5-dihaloadipoyl halide is then esterified under conditions wherein the ester of the dihaloadipoyl halide is allowed to remain in contact with the acidic compound, thus allowing the racemic diester to epimerize in the presence of the acidic compound to the meso form and then the meso diester spontaneously crystallizes. In the last stage, the meso diester produced is removed.

Abstract: The invention relates to a process for preparing an impact-modified plastic based on grafted crosslinked rubber particles, and also to an impact-modified plastic obtainable by the process. To prepare the impact-modified plastic, (a) particles of a crosslinked rubber are produced from a first monomer mixture which has a content of <50% by weight, preferably <5% by weight, particularly preferably <2% by weight, of diene compounds. The particles of the crosslinked rubber are (b) grafted with a second monomer or monomer mixture, with formation of a graft shell. Particles of the grafted crosslinked rubber are (c) added to a third monomer mixture, and the monomers of the third monomer mixture (d) are polymerized, with formation of a matrix. The process of the invention is simple to carry out and gives impact-modified plastics with very good mechanical properties, in particular with better resistance to weathering.
