Patent DE-2505890-A1 (DE)
Title: Keyless lock with human voice actuation - has filter for basic frequencies to be compared with stored frequencies
Inventor: HORN WERNER DR
IPC: G07C9/00
Filed: 1975-02-13
Abstract: The keyless lock is actuated by human voice. The lock has a microphone and a filter for filtering out characteristics basic frequencies of the authorised person. A discriminator with stored basic frequencies compares frequencies for opening the lock. The voice is directed against the receiver and the lock is kept open while this voice is produced. On stopping of the voice the lock moves into the closed position. The arrangement has a bistable multivibrator which connects the current when the voice frequencies coincide. The lock can be programmed for a number of voices.

Title: Stop mechanism for furniture drawers - engages in associated recess to abut stop face prevent further displacement
Inventor: FLAIG GEORG
IPC: A47B88/16
Filed: 1975-02-28
Abstract: The stop mechanism for furniture drawers comprises a stop member (12) which is attached to the drawer (3) or furniture body (2) at right angles to the direction of displacement, and during displacement of the drawer slides along the body or drawer. In one end position of the drawer (3) the stop member (12) comes opposite a recess (13) provided on the furniture or drawer and automatically engages in it and rams against the stop face (31) of the recess under the effect of a force which acts on the stop in the direction of the recess. Further displacement of the drawer is prevented. This mechanism can also be used for restricting the displacement movement of swivel plates and shelves as provided in kitchen units.

Title: Electro acoustic transducer with air space behind membrane - has space subdivided by sound attenuating material to maintain LF efficiency
Inventor: HAUN HERBERT
IPC: H04R1/22
Filed: 1975-03-03
Abstract: The electroacoustic transducer has a similar construction for both microphne and loudspeaker. The loudspeaker has the air space (10, 12, 13) behind the membrane (16) divided by sound attenuating material (9). This closed air spece is formed by a toroidal space (13) around the magnet (3), by axially parallel recesses (10) in an insert (8) coaxially around the magnet, and by a toroidal space (12) beneath the insert. The insert consists of a felt ring with the recesses on its inner surface. The advantage of this structure for the loudspeaker (and of a similar structure for the microphone) lies in being able to select the working frequency range without affecting LF efficiency.

Title: Measuring distance between e.g. reference plane and tunnel wall - using rotary laser beam scanner to increase measuring points
Inventor: BODLAJ VIKTOR DR ING
IPC: G01S17/50
Filed: 1975-03-11
Abstract: Laser beams are periodically deflected over the space containing the object, diffusely reflected by the object and recorded by a detector next to the laser which can only detect light from a given direction, whereby the distances are found from the time difference between the start of beam deflection and the detector signal. The beam deflector and two reflecting mirrors arranged obliquely behind the deflector rotate about a line linking the deflector and the mirrors to reflect the laser beams from the deflector to the inner surfaces of an object, e.g. a tunnel, and from these surfaces to the detector. The deflector and the mirrors may be fixed inside a rotatable tube.

Patent DE-2543492-A1 (DE)
Inventor: FRIEDRICH SIEGFRIED
IPC: H04J1/14
Filed: 1975-09-30
Abstract: In this method, the useful transmission bands are in the 12-28 kHz frequency range for one direction and in the 32-48 kHz frequency range for the other direction. A pilot frequency outside the useful transmission band, for which the 60 kHz carrier is used, is transmitted only in one direction and evaluated in one terminal station. In this terminal station, both the receive and the transmit signal are controlled in the +/- 4dB range. The other terminal station therefore has no control devices. <IMAGE>

Title: Winding reel starting circuit - with changeover switches before speed and armature current comparators for thyristor firing circuit
Inventor: SCHLOESSER HELMUT
IPC: H02P1/18
Filed: 1975-10-17
Abstract: A starting device for a winding reel, such as a warping mill for textile threads, uses a thyristor in the armature circuit of the d.c. drive motor. The thyristor is controlled by a pulse generator, in a cascade with a speed comparator and an armature current comparator. The former compares a voltage, supplied by a tachometer, with a voltage proportional to the desired speed. The latter compares the actual current with the desired current setting. Both comparators are preceded by a change-over switch. This requires few and uncomplicated elements to apply first a gentle tension and to observe the reel at a crawling speed before changing over to nominal full speed.

Title: Core-catcher for reactor meltdown has heat absorbing reservoir - of salts with temp. limited by latent or conversion heat
Inventor: MORLOCK GUENTER DIPL PHYS
IPC: G21C9/016
Filed: 1975-12-16
Abstract: A method of, and a device for, contg. a reactor core meltdown in a hypothetical nuclear accident comprises a "core-catcher" below the pressure vessel, sepd. by a barrier layer from the coolant and moderator. The core-cather contains a reservoir of a salt or salts mixt. intended for absorbing meltdown heat in the form of latent or conversion heat of the salt or salts mixt., thus preventing a temp. rise above a given value. After meltdown, penetrations through the reactor vessel, containment, concrete walls etc. are closed by foam. This foam, or suitable remeltable material such as thermoplastics, is produced from foam-forming substances by the meltdown heat. It prevents re-entry of coolant and moderator fluid. Specifically Boron salt or similar neutron-absorbing material is added to the salt to prevent criticality. There is improved absorption and removal of decay heat.
