Patent DE-4129864-A1 (DE)
Inventor: HAUTVAST HEINZ-JOSEF DIPL ING
IPC: B60R11/02
Filed: 1991-09-07
Abstract: A fixing device for an electronic apparatus with a preferably right-parallelepidedal casing, especially for use in a motor vehicle, is proposed, the apparatus being mountable and removable as quickly as possible even in unfavourable installation situations and mechanical repercussions on the casing caused by fixing being avoided. Provision has been made in particular for a support (4) to be attached to the apparatus casing (3) made of thermoplastic material. Furthermore, a holder (11) has been provided which is mounted at the point of fixing of the apparatus. The support (4) and the holder (11) are stable sheet metal parts which are joined by means of tongue and groove connections (30/33, 31/34 and 41, 42/28) in a plane parallel to the casing floor and are screwed together in the direction of the joint, preferably by means of a screw (19). <IMAGE>

Title: Surface treated aluminium@ alloy sheet for motor car construction -  used in making decorative coloured items, zinc phosphate layer having fine grained structure of uniform thickness
Inventor: TOYOSE KIKURO
IPC: C23C22/36
Filed: 1991-09-20
Abstract: Two stage process is used for surface treatment of an Al/Mg alloy sheet (3.5-5% by wt. Mg) to improve properties on phosphating, and also ways of using this sheet in making motor car components. In the first stage the sheet is surface cleaned by washing in a weak alkali (e.g. Na phosphate) soln. so that the oxide layer is removed and the surface Mg content falls in the range 0.035-0.5%, then in the phosphating soln. the plate is subjected to the effects of a soln. which has a free fluoride content of 75-800 ppm. USE/ADVANTAGE - Gives fine crystalline Zn phosphate layer of uniform thickness and high corrosion resistance. The coated plate can take colouring and be made into decorative car parts, e.g. mud guards. In an example, an alloy sheet was dipped (for 2 mins.) in a weak alkali (pH 10.5) at 40 deg.C; then 2 mins. in a Ti colloid soln. (1.5 g/l) at room temp.; and finally phosphate dipped (2 mins.) in a Zn phosphate soln. at 42 deg.C. This gave a fine grained Zn phosphate plating on the alloy sheet. Corrosion testing over a long period in salt water spray and other tests in different environmental humidities and temps. in competition with commercially available alternatives showed expected improvement.

Title: Bobbin sleeve spindle coupling - has buttons to grip sleeve with centrifugal balls within the buttons
Inventor: STAHLECKER GERD
IPC: D01H7/16
Filed: 1991-09-21
Abstract: At the sleeve coupling for a spinning or twisting spindle, a body to apply a centrifugal force is within the hollow zone, with a defined mass, within the sleeve holding button. The body, as a ball, has a smaller dia. than the innder dia. of the sleeve holding button. The guide is a radial drilling in the running part of the spindle, with a section cut back towards the spindle axis with only part of its end edge with a cut back section. The buttons are caps with their open end sides towards the spindle axis, and their outer contours generally matching the shape of the guides. The walls of the buttons are pliable against the side walls of the guides. The inner edge sof the buttons, towards the spindle axis, project outwards to grip behind the cut back section of the guide. The side walls of the buttons have recesses with the open end sides. The end sides of the buttons, away from the spindle axis, have profiles to engage into counter profiles at the inner wall of the bobbin sleeve in a coaxial direction. ADVANTAGE - The coupling system is cheaply made, and allows easy insertion and removal of the bobbin sleeve at the spindle, without resistance from the coupling

Title: garment press - has steam injectors at each press bowl
Inventor: WOHLLAIB EUGEN
IPC: D06F65/10
Filed: 1991-10-31
Abstract: A process to press articles of textile material, to follow laundering, is carried out in stages, with pressure and heating applied, which dries and smoothes the articles. In at least one stage, the whole width of the article is steamed. The appts. is also claimed. A three bowl machine is usual, each with a suitable drive and a heated pressure plate below. Each of the intermediate transfer plates as well as the initial feed plate is formed to have a full width steam injector passage and a supply box. The passage may be vertical or horizontal in the intermediate plate. The passage may include a baffle, which is operated from the central controller, to allow the steam to pass only at specified times. Each steam supply point has an internal tube with fine distribution holes, connected through electrically controlled valves to the steam supply, through the conditioner. From the central controller a connection is taken to sensors which determine the dryness of the article being pressed, and at each stage. The amount, temperature, and moisture content of the steam, and the time of application, are all controlled by the same unit. ADVANTAGE - The article being pressed is not subject to excessive localised drying, and avoids final stiffness, so that the articles have a softer handle.

Title: Adhesive marking label with detachable protective strip - has adhesion reducing effect of silicon strip-coating locally reduced so as to leave adhesive area
Inventor: TUIL TON VAN
IPC: G09F3/02
Filed: 1992-04-24
Abstract: The rear side of the label is only partly coated with adhesive, which is covered by a detachable silicon-coated protective strip. The adhesion-reducing effect of the silicon coating (8) is locally reduced or nullified, so as to leave an adhesive area (9) on the strip (7). This is done by chemical etching, applying a coating adhering to silicon, printing with highly adhesive oxidising ink, or glue reacting with silicon. The latter can be roughened at the adhesive area by corona or laser treatment. ADVANTAGE - The protective strip cannot be pulled right off due to mis-handling.

The wax is paraffin wax and/or microcrystalline wax, the pigment is a natural inorganic pigment and the filler is SiO2 and/or talcum. (I) contains a thixotropic agent. ADVANTAGE - Material (I) softens at 50-60 deg.C and becomes almost liq. at about 80 deg.C. It then remains workable for 1-2 hrs. at room temp. (and can even be cast or worked by brushing), after which it sets without firing to give a very hard, non-brittle material with good dimensional stability (if kept out of the direct sun and away from sources of heat). The material can be internally pigmented and/or painted after hardening, and is very suitable for artistic applications. Conventional modelling materials either have to be fired after shaping or do not have sufficient long-term dimensional stability.

Patent DE-4231968-A1 (DE)
Inventor: GEORGE TOBIAS
IPC: H05B41/38
Filed: 1992-09-24
Abstract: A clocked current supply circuit has a control arrangement (20) which supplies switching signals (21) to switching means (13) depending on a load state at the output side, and at least an inductive element (12). An at least temporarily active useful load (22) which is independent from the electric consumer (18), preferably an electric discharge lamp, is provided at the output side. The load (22) prevents idling of the clocked current supply by appropriately loading it, so that the system-dependent reaction time can be substantially shortened in the case of a short-time energy requirement by the consumer (18). The energy required in a short time can be supplied by the magnetic energy stored in the inductive element (12). This clocked current supply circuit is particularly useful for powering high-pressure electric discharge lamps (18), which are arranged for example in the headlamps of motor vehicles.

Since no solvent is used, there is no solvent emission. No gas stream is recycled in the desulphurisation stages, which increases the economy, and S is obtd. as prod. in both stages. The process is very flexible for gases of varying compsn..
