Title: Prodn. of flash-free FRP mouldings - by heating glass cloth and thermoplastic melt, placing in vertical flash mould, and feeding cold carbon di:oxide around male tool while pressing
Inventor: GETZKI KLAUS
IPC: B29C35/08
Filed: 1990-11-17
Abstract: FRP mouldings are produced by heating one or more layers of fabric material to 150 - 300 deg.C placing together with a thermoplastic melt, pressing at 1.1 - 500 bar pressure in a vertical flash mould and cooling. Whilst the material is being pressed, a liquid or gaseous coolant is fed into the mould round the flash gap. The male press tool has a sealing ring in the female tool and bores allow coolant to be fed through the male to a series of circumferential outlets. A glass cloth coated with polyproplene melt is heated by infra-red to 200 deg.C and placed in the mould; this material has a 25 wt.% fibre content. The mould is not heated. The male tool is then closed and the material is pressed at 5 bar. For 4 secs. while this pressure is built up 200 cm3 of CO2 at -50deg.C is fed into the gap between male and female tools. The pressure is maintained for 2 mins. For the procedure a variety of thermoplastics can be used; they can contain various additives. Various textile materials are suitable. ADVANTAGE - Eliminates the formation of flash and hence cuts out trimming operations and their related costs. (Dwg.0/2)

Title: Optical switch with bridge-over and through switch positions - comprises two opposing movable parts with switch positions accurately reproducible, output light wave conductor and one leading to photodidoe retained on common part
Inventor: ARNOLD WOLFGANG DR RER NAT
IPC: G02B6/32
Filed: 1991-01-16
Abstract: The input light conductor (E1) and that (E2) connected to the laser are located in holders on a first part (T1), the slide, and are thus in their relative positions coupled firmly to one another. In similar fashion, an output light conductor (A1) and one (A2) leading to the photo diode are retained on a common part (T2). The first part (T1) is formed as a movable slide and can be moved in a direction vertical to the light spread. The input light conductor (E1) is selectively connected to the output light conductor (A2) and thus with the detector and laser via the input light conductor (A2) to the output light conductor (E2). Alternatively the first input light conductor (E1) is directly connected to the output conductor (E2) in by-pass function. An additional third part (T3) serves as carrier for height guide of the movable light conductors, which are positioned in a deepened section (V) of it. The distance between the end surfaces of the light cnductors (a) must be selected as small as possible in order to achieve a high degree of coupling of the light. ADVANTAGE - As an optical switch with bridge-over and through switching positions rendering possible a reproducible changeover between these positions.

Title: Heating regulator with current-dependent reference monitoring - is dynamically adapted dependent upon operating current and ambient temp. and incorporates limiter and regulator in form of knob thermostats with combination of resistances
Inventor: OTT ERICH
IPC: F24H9/20
Filed: 1991-03-08
Abstract: The reference resistances (R1,R2,R3) are divided into two groups, but thermically form a unit. NTC resistances (R4,R5) are connected in series to the one group, so that the current distribution is temp.-dependent. These temp.-dependent NTC resistances are connected via moulded resin thermically to the reference resistances (R1,R2,R3). The moulded resin forces a temp. distribution and delay between the reference monitoring (R1,R2,R3) and the surface of the housing on the NTC resistances (R4,R5). The heating element (R6) on the heating regulator can be thermically coupled. If the NTC resistances (R4,R5) heat up, the one reference resistance (R3) is parallel-connected to the other two (R1,R2), and the current-dependent heat development reduces. The total resistances of the reference resistances (R1-R3) is always smaller than the heat resistance (R6). USE/ADVANTAGE - For the regulation and monitoring of electrical heating circuits.

Title: 1.3 Micrometre silicon@ photodetector integrated circuit - utilises Franz-Keldysh effect to reduce effective semiconductor band gap within central transition region
Inventor: STEIN KARL-ULRICH DR
IPC: H01L31/103
Filed: 1991-04-24

Abstract: In ball-race rotary couplings, e.g. for open-cast mining equipment, there are oil-lubricated ball-race base sections made up of segments to take the bearing balls carrying the structure which can rotate in relation to the chassis. In order to improve the sealing of the segments (1) against oil leaks from the separating seams and obviate the need to dismantle the ball-race rotary coupling every time the seal is renewed, there are U-shaped recesses (2) surrounding the ball-race (3) in the fronts of the segments (1), the arms (5) of which are open towards the in and outside of the ball-race base section and accept corded rubber or plastic sealing sections (6). The sealing sections (6) have sealing lips (9) on the segment side and a through hollow space (10) and are fitted entirely in one of the two adjacent segments. The sealing ring enclosing the ball-race base section and the internal oil retaining ring are interrupted in the region of the separating seams and closed off by easily removable components (7, 8). A leakage monitor is connected outside the sealing section (6) in the region of the transition between the web (4) and the arms (5) of the recess (2).

Inventor: BERNDORFER AXEL DIPL ING
IPC: F01L13/00
Filed: 1992-08-07
Abstract: In a valve operating system for an internal combustion engine, a pull-rod or rocker (1) which engages on the one hand with a gas valve (5) and on the other is supported on the cylinder head (3) is actuated by a cam (7) via an intermediate member (6). Here, the intermediate member (6) can be applied to the pull rod or rocker (1) in the direction of the actuating force of the cam (7) and can be decoupled therefrom. It is proposed that the pull rod or rocker (1) be fitted with a guide and adjacent free-floating section (16, 17), whereby the intermediate member (6) can be moved into these sections by means of an actuating device (11, 14). In the free-floating section (17) the intermediate member (6) can oscillate without actuating the pull rod or rocker (1), whereas in the guide section (16) it is fixed in the direction of the actuating force of the cam (7) on the pull rod or rocker (7).

Title: Monitor circuit for direction indicators of vehicle and trailer - tests functioning of all lamps prior to visual energisation and indicates defect at dashboard repeater lamp
Inventor: BERBERICH REINHOLD
IPC: B60Q1/38
Filed: 1992-10-10
Abstract: The monitor measures a test current via the resistors (RL, RR) and switches (SL, SR) when either a LH or RH lamp circuit (BLL, BLR) is operated and a difference threshold is used to indicate a defect. The test current is of, e.g. msecs duration in order to avoid visual response of the lamps (BLL, BLR), after which in healthy conditions normal flashing indication ensues for the selected direction. In the event of a defect in the selected circuit the flashing frequency is doubled by the IC (15) with dashboard indication by the lamp (LK). A defect in the non-selected circuit is similarly revealed the first time it is energised. USE/ADVANTAGE - Gives simple and reliable warning of vehicle/trailer indicator circuit fault each time operated. Difference threshold of LH and RH circuits is readily adjustable to allow for lamp tolerances. Comparison is made before visual response occurs.
