Patent DE-3123967-A1 (DE)
Title: One-man watercraft for sailing
Inventor: HORN HANS-JOACHIM
IPC: B63H25/10
Filed: 1981-06-19
Abstract: A one-man watercraft for sailing can be provided in which a floating body (1), if need be provided with a centreboard (2), carries a mast (3) arranged in a fixed upright position. One side of a sail (12) is fastened to the mast (3). The sail (12) is connected to a handle piece (14) for the sailor. In this arrangement, the floating body is provided with a rudder blade (7), rotatably mounted about an axis running from top to bottom and operable via an actuating member (9) acting via a lever arm, and has a standing surface for the sailor to use. In this craft, it is often desirable for both hands of the sailor to be free for operating the sail while keeping the simple setting of the direction of sailing. This is achieved if the actuating member (9) of the rudder blade (7) is arranged at the level of or deeper than the standing surface of the floating body (1) and is of suitable flat design for the sailor to put a foot on. So that the sailor has both hands free for operating the sail (12) on this watercraft, which has the non-tiltable mast (3), the actuating device (9) for the rudder blade (7) is designed in such a way that it is operated with the feet of the sailor. <IMAGE>

Title: Radar device
Inventor: WALLIS TIMOTHY ARTHUR
IPC: G01S13/10
Filed: 1981-07-07
Abstract: A radar device transmits a pulse and receives a corresponding echo pulse within the duration of the transmitted pulse. The echo pulse and part of the energy of the transmitted pulse are mixed in a mixing circuit (5) in order to generate a demodulated pulse whose duration is equal to the overlap of the transmitted pulse and the echo pulse. 
<??>The demodulated pulse is mixed in a mixing circuit (M1, M2) with bipolar reference signals (R1 and R2) which have polarity transitions at different times. A circuit (7) and a circuit (6) then form the integral over the duration of the modified pulse from a combination of inverted, non-inverted and suppressed parts of the modified pulse. The parts are defined by the transitions in the reference signals. 
<??>A pre-defined range law is achieved in this way.

The shield grid (13) eliminates useless current lines or converts them into zero-current field lines. The efficiency of such an appliance (10) is thus increased. <IMAGE>
Patent DE-3151414-A1 (DE)
Title: Radial flow turbine
Inventor: MAYER FRANZ-JOSEF DIPL ING
IPC: F01D17/16
Filed: 1981-12-24
Abstract: A radial flow turbine has guide vanes which can be inserted axially into the annular space surrounding the turbine wheel in order to change the angle of entry of the flow into the turbine wheel. Whereas, in normal operation, the guide vanes are removed completely from the annular space, they can be inserted into the annular space during other operating states, for example when accelerating the turbine. It is thereby possible to achieve an improvement in efficiency by simple means. Such a radial flow turbine is particularly suitable for exhaust-gas turbochargers of internal combustion engines since it permits more rapid response and running up of the rotor when accelerating.

Title: Method and device for determining the wall thickness with the aid of ultrasonic pulses
Inventor: DIEDERICHS ROLF
IPC: G01S15/14
Filed: 1982-03-18
Abstract: The invention proposes a method and a device for the automatic zero calibration of ultrasonic wall thickness measuring devices which operate in conjunction with transmit/receive test probes. For this purpose, both the transit time tE of the ultrasonic pulses on the receiver delay path (24) and the transit time of the ultrasonic pulses tS on the transmitter delay path (25) of the test probe (2) are measured at particular time intervals and stored in a memory (3811). The wall thickness d is then calculated with the aid of the relationship: <IMAGE> where: c = speed of sound in the item under test (1), tG = time needed by an ultrasonic pulse coming from the transmit resonator (21) to reach the receive resonator (22) after reflection from the rear wall of the item under test. For measuring the times tE and tS, an auxiliary transmitter (34) and an auxiliary amplifier (33) are in each case provided, preferably in addition to the transmitter (31) and the receiving amplifier (32) usually present in ultrasonic devices. <IMAGE>

Title: Dredger wheel
Inventor: ELSHOUT JOHANNES VAN DEN
IPC: E02F3/92
Filed: 1982-04-08
Abstract: A dredger wheel rotatable about a horizontal axis for a floating dredger has on its outer periphery a row of dredger buckets which are uniformly distributed over the periphery and are each of essentially U-shaped design in the radial cross-section of the wheel. The legs of the U-shaped buckets form a front inlet opening pointing in the direction of rotation. Over its entire length between the legs of the buckets, the outer peripheral surface has a passage fluidically connected to a suction tube (7). The suction tube extends with a suction head into the interior of the wheel. As viewed in the direction of rotation, the suction head, covering part of the wheel circle in the vicinity of the passage, has an extension passing through the passage and accommodated at the smallest cross-sectional area of the blades. In accordance with the direction of rotation of the dredger wheel, the dredger buckets work from top to bottom, and the extension lies below the axis of rotation of the wheel. <IMAGE>

Title: Encoder
Inventor: HEINE GUENTER
IPC: H02K3/04
Filed: 1982-05-12
Abstract: An encoder (2) (Fig. 1), in particular for detecting the speed of a motor (1), has a rotor (4) connected to the motor shaft (3), and a stator (5) arranged on the end face at a slight distance therefrom. The rotor (4) is provided with magnets of different polarity, while the stator (5) preferably has three windings which are mutually offset by 120 DEG  in each case in the circumferential direction of the stator (5). The three-phase construction of the encoder (2) produces, in particular, an output signal which remains approximately the same with respect to amplitude and which is particularly suitable for further evaluation. The windings are wound outside around a winding core disc (8) or a holder (12). By comparison with an otherwise conventional annular core winding method, such a winding is substantially simpler to apply. Provided at the rear of the stator (5) is a further printed circuit board (10), to which the winding ends and leads (11) can be connected and which also simultaneously serves to interconnect the windings. <IMAGE>

Title: Method for optical time division multiplex transmission via an optical waveguide of a switching system, in particular a telephone switching system
Inventor: SICHART FRITHJOF VON DR
IPC: H04Q11/04
Filed: 1982-08-23
Abstract: Method for optical time division multiplex transmission via an optical waveguide (opt) of a switching system with transmission-capable system devices (SC, SCs) which contain a control memory (SS, SSx) in whose memory spaces information is stored which indicates whether assigned time channels are occupied or not. Before the start of its transmission of control signals, the transmitting system device (SC), by means of its control memory (SS), selects a currently free time channel and seizes it and the system device (EC) designated for reception. The remaining transmission-capable system devices (SCx) also store this occupancy in their own control memory (SSx). Auxiliary devices (HC), also capable of transmission via the optical waveguide (opt) but without their own control memory (SS), are assigned to at least some of the transmission-capable system devices (SC, SCx). The auxiliary device (HC) co-uses the control memory (SS) of the assigned transmission-capable system device (SC) to check and seize time channels. The transmission-capable system device (SC) is in each case disposed spatially adjacent to its assigned auxiliary devices (HC), where the control memory (SS) is connected in each case via short lines (el1, el2, el4) to each of these adjacent assigned auxiliary devices (HC). <IMAGE>

Title: Device for adjusting the reed of a warping machine according to the warp-section coating thickness
Inventor: HOEPLI KURT
IPC: D02H13/16
Filed: 1983-01-26
Abstract: The reed is seated at the free end of a bar (9) which is pivoted about its pivot axle (8) by a lifting device according to the coating thickness of the warp section on the drum, in order to maintain the spacing between the reed and the yarn run-on point and the winding drum constant. To prevent the yarns running through the reed from continually rubbing against the same point on the reed teeth, the lifting-off movement has superposed on it an oscillating vibration which sets the reed in vibration approximately in its plane. For this purpose, the pivot axle (8) of the bar (9) is designed as an eccentric shaft which is permanently driven independently of the lifting-off movement via a chain wheel (19) and an eccentric drive shaft (18). As a result of rotatable mounting of the end of the bar (9), designed as an eccentric ring (15), on an eccentric bush (16) rotationally adjustable on the axle (8), the amplitude of the reed vibration can be adjusted between 0 and a maximum value which is lower than the reed height. <IMAGE>
