Title: Infinitely variable transmission
Inventor: MAY WERNER
IPC: B60K17/10
Filed: 1981-06-30
Abstract: The transmission represented in the drawing does not have any shiftable counter steps. Two hydraulic pumps (Fig. 1 and Fig. 2) are mounted on a flywheel. The two pumps are connected to one another by means of a pipeline. Lines and pumps are filled with hydraulic oil. The flow of oil is controlled by valves (Fig. 5). When the engine is idling the valves are opened, the oil can be pumped unrestrictedly in the circuit. The gears of the pumps (Fig. 3) roll on the cardan shaft (Fig. 7). At higher speed the valves (Fig. 4) close and the oil can no longer flow unrestricted in the circuit. The gears of the pumps (Fig. 2) are blocked and can no longer roll on the cardan shaft. The cardan shaft is transported. The smaller the flow of oil, the higher the speed. Possible applications of this invention would be in the motor vehicle sector and general engineering. <IMAGE>

Title: Process for fabricating a solid-electrolyte oxygen sensor element having a laminar structure, whose external electrode is deposited from the vapour phase
Inventor: TODA MASAYUKI
IPC: G01N27/28
Filed: 1981-08-12
Abstract: A process for fabricating an oxygen sensor element of the type of a concentration cell in the form of a layer structure of relatively thin layers. The first step of the process consists in the production of a sheet of a ceramic screening layer which serves as a substrate. Subsequently, an internal or reference electrode layer, a solid-electrolyte layer which conducts oxygen ions, and an external or measuring-electrode (working-electrode) layer is generated, which is made porous by sintering an electron-conducting powder which is applied to the solid-electrolyte layer face in the form of a paste. In order to improve the response of the oxygen sensor element, an additional measuring-electrode layer consisting of metal, such as platinum, and preferably not being thicker than 0.5 micron, is generated on the sintered measuring-electrode layer by physical vapour deposition techniques such as spraying, ion-plating or vacuum evaporation, while using a mask. The mask has an orifice, by virtue of which only the outer faces of the sintered measuring-electrode layer are exposed. In order to enhance the adhesive strength of the deposited measuring-electrode layer, a conducting ceramic-metal mixture is employed as the material of the sintered measuring-electrode layer.

Title: Cam arrangement for purl work flat-bed knitting machines
Inventor: OSTERTAG ALBERT ING GRAD
IPC: D04B15/36
Filed: 1981-09-11
Abstract: The invention concerns a cam arrangement for electronically controlled purl work flat-bed knitting machines with stitch transfer means. This cam arrangement extends the range of possible fabric constructions as a result of the fact that, of the plurality of selection points (I-V) for the selectable sinkers (28) for each carriage direction, a first selection point is assigned to the stitch transfer means and a second and third selection point each concern the working function of the needles (33). In the needle jack cam region (26) the third selection point is assigned an upthrow cam part (53, 53a) which acts on needle selectors (36) not influenced at the second selection point, so that the second and third selection points can be used to bring the needles (33) optionally into four different operating positions, namely: forming loops on the one set of needles; forming loops on the other set of needles; forming tuck loops on the one set of needles; and staying idle. <IMAGE>

Title: Resonant circuit
Inventor: LEIPERT EMIL ING GRAD
IPC: H03J5/24
Filed: 1981-11-07
Abstract: In a resonant circuit for several diode-switchable frequency ranges in input stages of television tuners, common radio-frequency, input and output connections (8, 13) are provided for both frequency ranges. The frequency ranges can be switched with the aid of switching diodes via RF-decoupled direct-current control connections. To achieve an optimum resonant-circuit Q without restriction of the tuning range in the frequency ranges and a simple switching capability, a separate resonant circuit (1-6, 21-26) is provided for each frequency range, the inductances (1, 2; 21, 22) of which are connected to in each case one direct-current control connection (U1, U2). To feed in RF power, one switching diode (7, 17) each leads from the input connection (8) to the inductances (1, 2 and 21, 22) of each resonant circuit whilst the output is also effected via switching diodes (12, 32) from each resonant circuit to the output connection (13). A direct-current control voltage (U1 and U2) fed to the inductances (1, 2 and 21, 22) is alternately applied in the forward direction and in the reverse direction, respectively, to the switching diodes (7 and 12 and 27 and 32, respectively), so that either the resonant circuit (1-4) or the resonant circuit (21-24) is connected to the input connection (8) and to the output connection (13), respectively. There is no switching diode inside these resonant circuits. <IMAGE>
