Title: Orbital engine to drive machines - consists of housing with ring-shaped rotor and pistons, which rotate about point outside rotor axis
Inventor: ANDER TOBIAS
IPC: F01C1/34
Filed: 1992-04-13
Abstract: The orbital engine consists of a housing and a ring-shaped rotor with three or more pistons. The pistons circulate about a pivot point (MG) outside the rotor axis. They simultaneously serve a sickle-shaped space inside and outside the rotor cage. Thereby they initiate intake and compression in one space, receive a drive impulse in the other space due to continuous fuel combustion, and cause ejection of the gas. The pistons are connected at the pivot point, to compensate for centrifugal forces. The centering bars of the pistons at the pivot point, move on a second shaft or a centering shaft (17). For this purpose, the rotor shaft (1) is hollow. The engine may have only one or two pistons. USE/ADVANTAGE - IC engine is without oscillating masses, has continuous combustion, saves material and energy during mfr. and use.

Title: Injection moulding process for plastics hollows, esp. for IC engines - has hollow metal or plastics core permanently moulded in for complex shapes, improved corrosion resistance and low cost
Inventor: HETTINGA SIEBOLT
IPC: B29C45/14
Filed: 1992-05-11
Abstract: Injection moulding process for hollow objects into which a hollow core is permanently incorporated and bonded by moulding a continuous layer of plastic round the core. The core may be of metal or plastic, pref. of two separate sections, esp. axi-symmetric halves, which are then joined to form the hollow core. USE/ADVANTAGE - Hollow plastic mouldings, e.g. pipes, pump housings, valves and pipe fittings, esp. of complex curvature for the motor vehicle and chemical industries. A moulded pipeline with flanges integral with a continuous outer plastic layer and tubular inner core of different material, plastic or metal, e.g. resistant to hydrocarbons, for a motor vehicle engine is specifically claimed. Compared with metal castings, this process avoids: a) core removal and risk of residual contamination b) rough internal (flow) surface from sand cores c) coat of material and mfr. of solid cast metal cores d) removal of metal sprues and runners and machining of fixing flanges etc. e) rough external surfaces f) poor dimensional accuracy g) cost and time of above finishing processes. Compared with blow moulding, this invention gives greater choice of plastic materials and greater freedom of design, e.g. for complex shapes or inclusion of fixing and connecting flanges. Compared with hollows moulded in sections and then joined, the seamless outer moulding avoids failure at seams under high internal pressure. Compared with above methods, this invention avoids machining and assembly for delicate electronic sensors; these may be precisely positioned and moulded in, esp. in inaccessible positions, also permitting (with transparent materials) flow visualisation. By use of plastics with differing physical properties for core and outer moulding, the former may be resistant, e.g. to corrosion, from internal fluids whereas the latter may have heat- and deflection-resistance suitable to the environment, esp. 'under the bonnet' applications. Also the cost of expensive material for the whole moulding is reduced when this is used only for the core (lining).

Title: Rotor adsorber for separation and recovery of minor components from gas streams
Inventor: EIGENBERGER GERHART PROF DR IN
IPC: B01D53/06
Filed: 1993-04-10
Abstract: Rotor adsorber for separation and recovery of minor components from gas streams, the desorption part, to minimise the desorption energy required, being connected in such a way that a desorption gas stream 1 is conducted in cross countercurrent flow to the rotor segments 2 and on its path first cools the rotor segments and removes the remaining residual loading, then in an external heat source 3 or in the rotor segment 8 is heated up to desorption temperature, then flows in cross countercurrent flow through further rotor segments and then passes into a separation device 13 where some 12 of the minor components are selectively separated off from the desorption gas. This separation can be carried out in a known manner by absorption (gas scrubbing), condensation, membrane separation or another adsorption process. The desorption gas leaving the separation device 13 is further conducted in cross countercurrent flow to the rotor segments 2 and gives off its heat and residual loading to these before it is either added to the dirty gas stream 10 to the adsorber or, with increase in pressure, is returned to the entrance 14 of the desorption gas stream. It is critical for the conduction of the desorption gas stream in the region of the source of heat of desorption and the separation device 13 that the hotter, less-loaded desorption gas is fed to the desorption segments on the clean gas side and the colder, higher-loaded desorption gas is fed to the dirty gas side. <IMAGE>

Title: Front toe-piece of a ski binding
Inventor: KLUBITSCHKO GERD
IPC: A63C9/085
Filed: 1993-05-12
Abstract: The invention relates to a front toe-piece of a ski binding with a support member bearing two side toe-pieces which forms the coupler of a four-bar mechanism. The side toe-pieces are held immovably in the rest state in relation to the support member. After a given pivoting out of the support member, however, the side toe-piece lying at the front in the direction of movement pivots out to release the boot sole. Arranged between the side toe-pieces on the support member is a lever which supports the side toe-pieces mutually detachably. This lever releases the respective side toe-piece at the end of the pivoting-out movement of the support member. Additionally, there is formed on the lever a nose which interacts with a resilient element in such a manner that it ensures a centering of the rocker-like lever when the latter is restored.
