Title: Apparatus for producing or machining gears
Inventor: BAUMSTARK MAX
IPC: B23F21/10
Filed: 1993-05-19
Abstract: An apparatus for producing or machining gears according to the principle of gear shaping has a work-holding table for a work gear, a shaping spindle with a cutting gear of considerable hardness fastened to it, a shaping drive setting the shaping spindle in a reciprocating movement if need be with superimposed rolling motion, and an infeed drive. To reduce the design cost and improve the vibration rigidity, provision is made for the cutting teeth of the cutting gear to lie over their entire extent in the cutting direction on a circular-cylindrical enveloping surface and to have one cutting edge each on the opposite end faces of the cutting gear, and for the cutting gear to be fed in by one chip width in each case during the shaping and return stroke of the shaping spindle. The conventional lifting of the cutting gear in gear shapers and the disadvantages associated with this are eliminated by these measures.

Title: Retractable roof for vehicles
Inventor: TOMFORDE JOHANN DIPL ING
IPC: B60J1/18
Filed: 1993-07-23
Abstract: The invention relates to a retractable roof for vehicles, in particular for two-seater cabriolets (convertibles), with a roof shell which has a roof panel and rear roof pillars and which can be moved forwards longitudinally, together with the roof pillars, into a compartment between lateral end walls of the vehicle body, after which the roof is held upright in a transverse plane of the vehicle, and furthermore with a rear window for a window opening which is delimited at the sides by the roof pillars and at the top by the roof panel, and with guide means for the motion control of the roof shell and rear window, the rear window being moved, under control, out of its in-use position relative to the roof shell into an out-of-use position in which its window surface lies a short distance opposite the roof panel. So that, during the retracting process of the roof, considerable clearance in front of the roof pillars is not required and nevertheless the advantages of the roof in terms of stowage space are maintained, the roof shell is lowered, under control, via sliding guides arranged laterally in the compartment, the sliding guides being arranged independently of the guide means of the rear window, and the rear window being mounted on the roof shell in a manner which allows it to be displaced longitudinally via sliding guide means assigned to it.

Title: Battery charging unit for supplying charging current to battery - has unit for determining and storing battery voltage occurring after expiry of given time duration after beginning of charging operation.
Inventor: MATSUMOTO TOSHIO
IPC: H01M10/44
Filed: 1993-08-11
Abstract: A comparator is provided for comparing the battery voltage (V1) with a predetermined voltage and for differentiating the battery related to the rated voltage. A timing unit determines the time point of the transition of the battery voltage from a rising tendency to a falling tendency. The unit is activated if the battery voltage has reached the sum of a predetermined potential difference(dVS) and the battery voltage(V1), which has occurred after the expiry of the predetermined time(T1). A unit is provided for ending the supply of charging current, if the timing unit for determining the time point has detected the said time point, whereby the predetermined time duration(T1) essentially is established the same as the time duration. In which an abrupt alteration of the battery voltage produced at the beginning of the charging operation of a low charged battery, is faded out. So that the predetermined potential difference(dVS) of the rated voltage is established corresp. to the battery to be charged. ADVANTAGE - Common to respective time point, complete charging of batteries with different rated voltages is determinable. Time point of complete charge can be correctly determined if supply voltage alters in time.

Title: Protective device for a blower of an internal combustion engine
Inventor: SCHLEIERMACHER HERBERT
IPC: F04D29/70
Filed: 1993-11-04
Abstract: A known protective device for a blower of an internal combustion engine is manufactured from metal and has basically proved to be reliable and durable in practice. However, a disadvantage is the high outlay on production since first the individual fins of the grating have to be bent and then laid on top of one another and welded together. To reduce the outlay on production, the grating 1 according to the invention can be injection-moulded, there being arranged in the centre of the grating a plastic plate 2 whose centre contains an injection point. From the plastic plate 2 there extend inner fins 3a which branch in a bifurcation 4 into outer fins 3b. The fins 3a, 3b are connected to one another via ring fins 5a, 5b, 5c, 5d and, together with optimum design, take account of the need for collision protection. <IMAGE>

Inventor: CHALOUPKA HEINZ
IPC: H01P7/08
Filed: 1994-10-11
Abstract: The invention concerns a resonator, preferably a disc resonator, comprising two electrically conductive layers (2, 4) which are made of a high-temperature superconductive material, are disposed vertically on top of one another, and are separated from each other by an insulating layer (3). An electrically conductive layer (2, 4) has an outline delimited by a peripheral edge (R) and lines of an electrical current are formed in one of the two layers (2, 4) when a preselected resonant frequency acts on the resonator. In order to construct this resonator such that it is as powerful as possible, the geometry, in particular the outline of a conductive layer (2) (structured layer), is selected such that substantially only current lines (S) which intersect the edge (R) (in an imaginary extension) occur in the structured layer (2) at the resonant frequency.
