Patent DE-3509229-A1 (DE)
Title: Fin
Inventor: FRANK DIETER
IPC: B63B35/79
Filed: 1985-03-14
Abstract: A fin, in particular for surfboards, consists of a main fin (1), which forms a stabilising surface running in the longitudinal direction of the hull, and, at a distance from the main fin (1), a further front and/or rear guide fin. In order to avoid separation of the water-flow side opposite the oncoming-flow side at the outer skin of the main fin (1) even in extreme cases, provision is made for the front guide fin or the front and rear guide fin to consist of a double guide fin (5) having at least one pair of fin blades (13) lying uniformly offset relative to the stabilising surface (11) of the main fin (1) while forming a gap (24), the double guide fin (5) being arranged laterally offset in the area of the front half of the main fin (1) (Fig. 1). <IMAGE>

Title: Hydrostatic transmission, especially for a vehicle drive
Inventor: PARISI ROBERTO
IPC: B60K6/12
Filed: 1985-05-22
Abstract: The primary unit and the secondary unit of a transmission comprising hydrostatic machines for a vehicle drive functions in a closed cycle with accumulators connected to the high pressure and low pressure line. The secondary unit is speed-controlled and the primary unit is power-controlled. As a result, for acceleration of the vehicle the additional pressure medium required is drawn from the high pressure accumulator and stored in the low pressure accumulator. Conversely in deceleration or braking the pressure medium stored in the low pressure accumulator is fed back into the high pressure accumulator. An optimum operating behaviour of the primary unit is obtained by the power control. With the pendulum volume flowing to and fro between the high pressure and low pressure accumulator the quantity of working medium required for the drive is reduced and the weight of the vehicle is reduced. <IMAGE>
Patent DE-3525672-A1 (DE)
Title: Device for monitoring the air pressure in a pneumatic tyre
Inventor: TRNETSCHEK ROBERT
IPC: B60C23/04
Filed: 1985-07-18
Abstract: The device has two chambers (24, 34) which are sealed off from one another by means of a valve (44). The valve (44) is connected to a valve (56) via a plunger (38) which in the normal state closes off a channel (62) at whose outer end (66) a vent hole (68) is arranged. The device is screwed onto a valve (16) of a pneumatic tyre so that the air pressure prevailing in the tyre can be built up in the chamber (24) and in the chamber (34). After the pressure in the chamber (24) and the pressure in the chamber (34) have been matched to the air pressure of the tyre, the valve body (44) is seated on its valve seat so that the chamber (34) is sealed off with respect to the chamber (24). In the event of a defect in the tyre, the air pressure in the tyre drops and thus in the chamber (24), as a result of which a diaphragm (42) which is connected to the valve body (44) is deformed which simultaneously brings about a displacement of a plunger (38) which lifts off the valve body (44) so that a connection of the channel (62) to the chamber (24) is produced. In this state, air can flow outwards out of the tyre into the chamber (24) and the chamber (62) so that the vent hole (68) is activated. A cap (70) is fitted over the outer end (66) of the channel (62), which cap is forced off when air flows outwards through the channel (62). The vent hole (68) can produce sounds in the ultrasonic range so that monitoring displays can be excited in the passenger compartment of the vehicle by way of suitable transformation means ...

Patent DE-3537133-A1 (DE)
Title: Pull-out (extending) table
Inventor: HECKMANN PETER
IPC: A47B1/03
Filed: 1985-10-18
Abstract: In the case of a pull-out table, a maximum of four extension leaves can be inserted independently of one another between two table leaves. For this purpose, the user sets the desired number of extension leaves at changeover switches assigned to the table leaves. After that, he pulls out the table leaves, automatically lifting the desired number of extension leaves from an initial position located beneath the table leaf. If an extension leaf is required on one side of the pull-out table, the two superposed extension leaves are lifted so far that the upper side of the upper extension leaf is lifted out further, so that the upper side of the lower extension leaf is flush with the upper side of the pulled-out table leaf. If two extension leaves are required, the two superposed extension leaves are aligned with the upper side of the pulled-out table leaf. After this, the user has to fold over the upper extension leaf. For this purpose, the two extension leaves are connected to one another by means of a hinge. After the folding over, the two extension leaves and the table leaf form a flush table surface. The extension leaves are lifted by means of lifting arms of different length, the selection of the lifting arms being carried out by means of a controllable detent.

Title: Method and arrangement for forming the output currents of a three-phase pulse-controlled invertor
Inventor: KUHN WERNER DIPL ING
IPC: H02M7/5387
Filed: 1985-11-13
Abstract: In the case of operation of a three-phase, pulse-width-modulated invertor (5) which is supplied on the input side from a DC voltage intermediate circuit (1) and, on the output side, supplies a rotating-field machine (15), it is necessary in order to achieve a high-quality drive behaviour to detect the invertor output currents (iR, iY, iB) and to supply them to the control and regulating device (12) for the invertor. A method and an arrangement are described, in the case of which method and arrangement it is possible to model the invertor output currents (iR', iY', iB') without any additional current transformers on the machine side. For this purpose, a current modelling device (13) is provided which derives the invertor output currents (iR', iY', iB') from the measured intermediate-circuit current (id) as a function of the switching commands (SR, SY, SB) of the control and regulating device (12) to the invertor valves (6 to 11), and of the phase angle ( phi 1) of the rotating stator voltage (U1). Said method and arrangement can be used, in particular, for transistorised invertors. <IMAGE>

Title: Apparatus and method for evaporating liquids
IPC: B01D3/08
Filed: 1986-05-31
Abstract: An apparatus (1) (Fig. 1) serves for evaporating liquids under vacuum. The apparatus (1) has a distillation flask (2) having liquid (3) situated therein, a condenser (4) having a collection flask (5), a vacuum pump (6) and a shut-off valve (8), a temperature sensor (13) and an evaluation and control device (14). With the aid of the temperature sensor (13) immersed in the liquid (3), the temperature of this liquid is measured during the supply of heat and the pressure reduction by the vacuum pump (6). From a time point (boiling point), at which the temperature increase ceases, and a fall in temperature is then established, the pressure lowering is shut off. The fall in temperature results, inter alia, from the suction briefly continuing even when the boiling point is attained. Since measurements are made directly in the liquid (3), it is possible to shut off the vacuum pump (6) and seal the system by the shut-off valve (8) with a very short reaction time from the boiling time point, so that virtually no solvent loss occurs. <IMAGE>
