Patent DE-3804333-A1 (DE)
Title: Device for changing the timing angle between a machine part and a drive unit actuating the latter
Inventor: AUSTERMANN JOSEF
IPC: F16H25/14
Filed: 1988-02-12
Abstract: The device is used to change the timing angle between a machine part (1), which is preferably guided in a manner which allows it to be adjusted in linear fashion and is moved backwards and forwards periodically, particularly a valve element of the intake and/or exhaust valve of an internal combustion engine, and a drive unit (2) actuating the machine part (1). The adjustment of the timing angle takes place as a function of the operating states such as, for example, the rotational speed of the drive unit (2), the machine part (1) being held by a guiding part (3) which is guided in a manner that allows it to be adjusted in the direction of motion of the machine part and is in positive engagement with the drive unit (2). The machine part (1) can execute an adjustment stroke relative to the guiding part in its direction of motion, this adjustment stroke being limited axially on both sides and being damped by damping means, for which purpose two chambers (6, 7) are formed between the machine part (1) and the guiding part (3), these chambers being filled with damping medium, being connected to one another via at least one flow passage (4, 5) and having a variable volume. The volume of the chambers (6, 7) is determined by the respective axial position of the machine part (1) relative to the guiding part (3) and changes in inverse proportion to the latter. <IMAGE>

Title: Instrument lid e.g. for thermometer for the use of sheet-metal beverage cans as solar-energy cooking receptacle and as advertising medium
Inventor: SCHELOWSKY MICHAEL
IPC: F24S20/30
Filed: 1988-02-27
Abstract: Sheet-metal beverage cans from large exporting companies are to be found world-wide as empty articles and as such could be well suited to the cooking of food in such individual portions of 0.3 and 0.5 litres using solar energy, if other forms of energy are either not available (e.g. in tourism) or have to be saved or avoided for environmental and political reasons, and also to eliminate poverty. Free solar energy can be used to cook food in sheet-metal cans if a deep-black collector layer is provided around the lateral surface and the can is brought into the focal line of a light-reflecting hollow space, and furthermore if the end face of the can is given an opening which is to be closed with a lid, and the cooking process in the can contents is able to be monitored and regulated. For this purpose, use is made of the instrument lid proposed here, consisting of a plastic housing with an insertable bimetallic strip thermometer. In addition, an electronic measuring device with digital display can also be fitted. The inventive concept is based on the everyday components: 1. sheet-metal can as empty article and waste, 2. plastic injection-moulded part and 3. bimetallic strip thermometer, to be combined to form a new type of product unit, with an advance in the preparation of food portions and the practical use of the ...

Patent DE-3812614-A1 (DE)
Title: Lamp and lamp support for the headlight (headlamp) of a motor vehicle
Inventor: CAVANNA JEAN
IPC: F21V19/00
Filed: 1988-04-15
Abstract: The invention relates to a Type H2 lamp having a potted glass bulb (1) which encloses a filament (2) which is connected to electrical contacts which project outwards on the bulb, interact with a lamp support and enable the mechanical mounting and electrical connection of the lamp. The contacts are formed by a solid metallic vane which is coated, at least in the regions which are intended to interact with the lamp support, with at least one outer coating layer of a metal, for example aluminium or a nickel/aluminium alloy, which oxidises on the surface at the normal operating temperature of the lamp. In this way, an oxidation passivation skin is formed on the surface of this coating layer, which skin is stable or has little tendency to evolve, prevents the development of corrosion of the contacts and limits the voltage drop on the interface between the contacts and lamp support. The same treatment is advantageously used on the contacts of the lamp support which supports this lamp. <IMAGE>

Title: Method for connecting the cover plate and/or foot piece on the one hand to the blade on the other by means of a brazing or jointing process
Inventor: FRIED REINHARD DIPL ING
IPC: B23K33/00
Filed: 1988-09-17
Abstract: The cover plate (5) and/or foot piece (10) are connected to the blade (1) to form a turbine blade by a brazing or jointing process in that, in order to produce jointing surfaces, the components to be connected are bevelled at an angle ( alpha ; ss) of 15@ to 75@ to the longitudinal axis of the blade according to a ruled surface in order to form tapering neck (8), openings (6) and depressions (11). The parts having wing-shaped cross-sections and each accurately fitting on one another are fitted together, subjected to a compressive force acting in the longitudinal direction of the blade, brought to brazing or jointing temperature and the entire assembly cooled again. Due to the compressive force, local deformations and relative movements are produced on the jointing surfaces of the components (1, 5, 10), which lead to an intimate metallurgical bonding. Preferred: brazing processes incorporating a layer of filler metal (13) between the ruled surfaces of the parts to be connected. Improvement and speeding up of the connecting process by vibration of the components transversely to the direction of the compressive force. Preferred application: oxide dispersion-hardened nickel-based super alloys for the blade (1). <IMAGE>

Title: Automatic sofa bed
Inventor: WOLFF HANS-DIETRICH
IPC: A47C17/22
Filed: 1988-12-07
Abstract: In the USA there has already existed for quite a long time a sofa bed which, like the one described here, by simply unfolding using only one hand offers an immediately usable, i.e. "made" bed, while in the case of all other sofa beds offered on the market, after unfolding requiring effort, the user, tired at night time, is called upon to carry out a time-consuming and extremely cumbersome "bed construction". The steel construction used in the USA product is, however, very costly and therefore in general too expensive for other markets. Moreover, old-fashioned netting-wire frames are used, which do not meet the present-day requirements as far as personal hygiene and comfort are concerned. In contrast, the present invention offers a very simple and much more reasonably priced solution, in which, without sacrificing stability, wood can be used and also the use of modern spring-wood frames in place of netting-wire frames is envisaged. The production costs should not be considerably above those of conventional, but old-fashioned and impractical constructions.
