Patent DE-3824539-A1 (DE)
Title: Engine, especially internal combustion engine
Inventor: HOELTER KARL
IPC: F01C1/063
Filed: 1988-07-20
Abstract: The engine is provided with ring segment cylinders (3) and ring segment pistons (4) rotating about a centre axis (2), which are fixed to separate support bodies (9, 10), which are movable relative to one another and are pivotably mounted independently of one another. The support bodies (9, 10) are to be operated with a single seal by drive pulses acting in the same direction and merging into one another. This requirement is achieved in that the ring segment piston (4) in each case forms a piston carrier (4a), that succeeding ring segment cylinders (3) or ring segment pistons (4) are connected to one another by means of a support base (14) and form a rotating unit, and that compression or pressure, combustion or work or intake or exhaust chambers (6, 7, 5, 8) are respectively formed between support base (14) and ring segment piston (4). <IMAGE>
Patent DE-3827131-A1 (DE)
Inventor: ATKINSON WILLIAM
IPC: H04N7/26
Filed: 1988-08-10
Abstract: The method consists of enriching binary, video information in zeros through shifting and Exclusive ORing the video image with itself. A number of methods are attempted in the shifting and Exclusive ORing process in order to determine the method which yields the optimum zero enriched image. The zero enriched image is then encoded and the encoded information stored. Run-length encoding is preferred. Upon retrieval, the information is decoded and an Exclusive OR and shifting process is done to obtain the original video information.

Title: Positive displacement machine according to the spiral principle
Inventor: JETZER GREGOR
IPC: F04C18/02
Filed: 1988-11-21
Abstract: In a positive displacement machine for compressible media, each casing half (7, 7') has two pumping chambers (11, 11') which are offset with respect to one another by approximately 180@ and run spirally from an inlet (12, 12') to an outlet (13). Assigned to each pumping chamber there is a displacer which engages the latter and, as a spiral strip (3, 3'), is retained perpendicularly on a disc-shaped rotor (1) which can be eccentrically driven with respect to the casing. For the purpose of guiding it, there is provided in the casing at a distance from a first drive eccentric arrangement (23, 24), a second guide eccentric arrangement (26, 27). The eccentric of the second eccentric arrangement is formed by a hardened and ground cylindrical pin (26) which, at the displacer-side end of the guide shaft (27), is pressed into an eccentric hole (33). The hole (33) has a greater depth than required for the pin (26) to be pressed in, specifically by the same degree to which the pin projects from the hole at the front end of the guide shaft (27). <IMAGE>

Inventor: CASPERS JOHANNES
IPC: G11B17/035
Filed: 1988-12-27
Abstract: 1. Loading device for a recording and/or playback apparatus for recording discs of different diameter. 
<??>2.1 Apart from customary CDs, in the meantime a CD of smaller diameter, the so-called mini CD, is on the market. To be able to play a mini CD in a CD player, it has to be manually inserted into a usually ring-shaped adaptor. 
<??>2.2 In order to save the user both from requiring this accessory and from the tiresome handling it involves, the loading device (N) has a depression (V) for receiving the disc (CD) of the larger diameter, the edge of which secures the disc (CD) against shifting. A clearance (AS) for a lowerable rest (L) is provided in the centre of the depression (V). On the circumference of an imaginary circle, the diameter of which corresponds to the diameter of the smaller disc (M), there are arranged on the rest (L) at least three supports (S), which on the one hand secure the smaller disc (M) against shifting and on which on the other hand the disc (CD) of larger diameter rests. By lowering the rest (L) by means of an arm (AR), which is pivotally fastened on the loading device (N), an inserted disc is brought into the playback position.

Title: Valve flap system for paragliders
Inventor: FESSLER GERHARD DIPL ING
IPC: B64D17/02
Filed: 1988-12-28
Abstract: In the case of previous commercially available paragliders, the chamber internal pressure which is necessary to form a profile capable of providing lift, is built up by relatively large air inlet openings on the individual cells. This profile has very poor aerodynamic characteristics. This situation is intended to be improved by the arrangement of a valve flap system along the air inlet openings. A valve flap system, consisting of a two-piece (a fibre fabric which is impermeable to air and a gauze fabric which is air-permeable) moving cloth strip, is arranged on each individual cell. In consequence, a closed profile is produced when the chamber internal pressure is adequate, the aerodynamic characteristics of which profile are greatly improved and whose flying performance is in consequence considerably improved. Figures 9, 10, 11, 12 page 10. The arrangement of the valve flap system enables the production of considerably higher performance paragliders without any detrimental effects in the field of safety. <IMAGE>
Patent DE-3900320-A1 (DE)
Title: Means of optimising a drive unit with electronic sensing of the specific characteristic engine data maps
Inventor: WIELAND RAINER
IPC: F16H47/04
Filed: 1989-01-07
Abstract: Until now there has been no comparable drive system in which the engine control and transmission ratio of the gears are matched to one another in such a way that in every load range the engine can be operated in the specifically most favourable characteristic map. In this optimised drive system, the engine and gear system are compensated with respect to one another in such way that in every load range the engine adjusts itself in the specifically most favourable characteristic map, specifically in such a way that fuel consumption and emission of pollutants are in the most favourable ratio with respect to the power required. This drive system is particularly suitable for vehicles of the higher performance class in which high efficiency and an infinitely variable drive system with a high degree of comfort are required, such as e.g. in buses or lorries.

Title: Method of inserting a green tyre into the space between upper and lower mould parts of a tyre vulcanising press
Inventor: HASEGAWA AKIRA
IPC: B29K21/00
Filed: 1989-03-23
Abstract: The invention relates to a method of inserting a green tyre into a space between upper and lower mould parts of a tyre vulcanising press, having upper and lower mould part arrangements or units which are movable in relation to one another, which is characterised in that an upper bead of the green tyre is pressed into a bead ring of the upper mould part by means of a device which supports or bears the upper bead of the green tyre and is perpendicularly movable, gas is introduced into a bladder for inflating the latter, during which a raising or moving up of an upper-part fixing ring of a bladder holder mechanism fitted on the lower mould part unit is inhibited or prevented, and a lower bead of the green tyre is pressed into a bead ring of the lower mould part, utilising the expansion force of the bladder. Since the bladder is closed in an airtight manner, the lower tyre bead can be pressed effectively and reliably into the bead ring of the lower mould part.

Title: Prodn. of deep drawn pressings to precise dimensions - by upsetting blank to produce rim of increased thickness
Inventor: JENSEN NIELS DUE
IPC: B21D22/22
Filed: 1989-10-26
Abstract: It is difficult to produce deep drawn pressings with accurate dias. becausee of the 'springback' of the metal when the pressing is removed from the press tools.   This problem is overcome by first upsetting the rim of the blank from which the pressing is produced. The deep drawing operation is then carried  out to produce a cylindrical pressing with a thick rim (12). This thick rim is then embossed to produce internal or external projections.  The dia. of the surfaces of these projections can be held to a high deg. of accuracy. USE - Mfr. of deep-drawn pressings.
