Title: Flame-resistant polyethylene terephthalate compositions
Inventor: KRIEK GEORGE R
IPC: C08L67/02
Filed: 1987-05-26
Abstract: It has been found that flame-resistant, reinforced, thermoplastic moulding compositions based on polyethylene terephthalate have, after addition of a sufficient amount of a particular ionic elastomer, a reduced tendency to drip during burning. The addition of the antidrip agent according to the invention is not at the expense of the physical and mechanical properties of the compositions.

Patent DE-3718863-A1 (DE)
Title: Screw pump
Inventor: MEICHSNER MICHAEL DIPL ING
IPC: F04C2/16
Filed: 1987-06-05
Abstract: The use of screw pumps for discharge flows under 2.5 l/min at a speed of 1450 r.p.m. has not been commercially viable to date, because the constructional effort and the efficiency of previous pumps are too poor. These shortcomings are overcome by the features of the present invention because the number of sealing points is minimised, and the sealing points and screw spindles themselves can be manufactured more precisely and with smaller clearances.

Title: Lubricant circuit of an engine having a lubricant filter
Inventor: LUGS WERNER
IPC: F01M1/16
Filed: 1987-12-15
Abstract: In a lubricant circuit of an internal-combustion engine, in which lubricant conveyed in excess is returned directly into the reservoir via a return line by means of a pressure-regulating device, a lubricant filter is provided in the said return line. In simple instances, this lubricant filter can carry out the filtration of the entire lubricant circuit, and as a supplement a further additional lubricant filter, but in that case with clearly reduced flow resistance, can also be provided upstream of the branch to the individual lubricating points. The flow resistance of the lubricant circuit is markedly reduced as a result of that measure.

Patent DE-3809788-A1 (DE)
Title: Night vision equipment installed in aircraft pilot's helmet
Inventor: ELLIS STAFFORD MALCOLM
IPC: G02B27/00
Filed: 1988-03-23
Abstract: A forward looking objective (19) is mounted within each side of the helmet (11) at temple level. Behind it, a mirror reflects incoming light through an image intensifier (25), whence successive reflections within a protective housing (49) direct the image to an eye-piece (15) situated, in the operational condition, immediately before the pilot's eye (E). The housing and eye-piece, when not required, are retracted into the side of the helmet, rotating, on bearings (12) about a vertical axis (YY). The eye-piece has an internal surface transparent to the directly viewed scene and reflecting the intensified image perceived via the objective. It also provides, superimposed on these images, a head-up display generated by cathode ray tube elsewhere within the helmet.
Patent DE-3817806-A1 (DE)
Title: Tool for producing encircling undercuts
Inventor: HERB ARMIN
IPC: B23B51/00
Filed: 1988-05-26
Abstract: The tool for producing undercuts (12) has a support body (1) set in rotation and a cutting blade (2). The cutting blade (2) is supported with a supporting surface (4) on the base (3) of a recess in the support body (1). The base (3) and the supporting surface (4) are inclined increasingly away from the free end face (6) of the support body (1). Consequently, when the support body (1) is displaced, the area of the cutting blade (2) opposite the supporting surface (4) is deflected, while the end face (11) rolls without radial displacement on the bottom (12a) of the blind hole (12). <IMAGE>

Title: Dental ceramic compositions and their use
IPC: A61K6/06
Filed: 1989-03-25
Abstract: The trituration of dental ceramic compositions composed of ceramic powder and a trituration liquid which, removed by aspiration or drying, causes a certain stability is state of the art. The present invention describes a material combination between the dental ceramic composition and a light-curing plastic. After modelling, the composition mixture is photopolymerised, removed without deformation and baked in a ceramic furnace, during which the light-curing plastic incinerates. This material combination is particularly suitable for direct intraoral use as shoulder composition, for relining ceramic semifabricated components and for direct and indirect production of inlays and onlays.

Title: Balanced facing head
Inventor: MUTH WOLFGANG DIPL ING
IPC: B23B29/034
Filed: 1989-04-03
Abstract: A facing head for a machine tool is described in which a tool slide and a counter slide are radially displaceable in opposite directions for the balancing. The counter slide is mounted in a central recess of the tool slide in such a way that the centres of gravity of the tool slide and the counter slide move virtually on the same radial line during a tool adjustment. In this way, the dynamic unbalance occurring when slides lie axially one behind the other or radially next to one another is avoided. <IMAGE>
