Title: Automatic feed system for snapshot viewer - uses cassette with sliding half and flaps lifting snapshots in turn from stack to viewing position
Inventor: WEINBERG ULLI
IPC: G09F11/30
Filed: 1980-04-15
Abstract: The viewer for snapshots or slides uses a cassette (11) containing a stack of snapshots which is inserted into an opening in the casing of the viewer so that each snapshot is viewed in turn by sliding one end (14) of the cassette in and out. The cassette consists of two parts, the inner part (14) holding the stack, and the outer part remaining inside the viewer. The outer part incorporates two pairs of spring-loaded flaps (32), one pair behind the other, so that as the inner part is pulled out, the bottom snapshot is extracted from the stack and swung upwards against an opening around the top surface (26) into a viewing position. When the inner part is pushed in again, the snapshot is returned to the top of the stack. The next snapshot is then ready for viewing.

Title: Integrated transistor stabilising circuit - uses high pre-resistance and auxiliary transistor with same channel width
Inventor: REICHERT HANSJOERG DIPL PHYS D
IPC: H03F3/345
Filed: 1980-05-08
Abstract: The circuit has an operating transistor (TrB) with at least one gate electrode, an auxiliary transistor (TrH) and a preresistance (RV) with a high ohmic resistance value. The operating current through the generating transistor (TrB) is stabilised by connecting the pre resistance (RV) between the gate of the latter transistor (TrB) and the source and gate of the auxiliary transistor (TrH). The short circuit current between the drain and source of the operating transistor (TrB) is less than the required operating current. The two transistors (TrB,TrH) have the same channel width and are made by the same mfg. process. Pref. an auxiliary current (IH) is fed to the junction of the gate and drain of the auxiliary transistor (TrH) supplied from an external voltage source (UH) via an integrated auxiliary resistance (RH).

Title: Tank filling safety and limit transducer test unit - measures current before and during filling enabling defect
Inventor: BAUER MANFRED ING GRAD
IPC: B67D7/32
Filed: 1980-10-09
Abstract: A test arrangement for tank filling safety devices and limit transducers is applicable to tanks both beneath and above ground. The current from the filling safety device to the limit transducer is measured before filling commencematerial tested are made at the constant indentor force value. This force value is determined from the calibration curve on which the dependence of ultrasonic signal amplitude reflected by the indentation on the load force and pipe sample diagonal is plotted. The core on which the tube is initially rolled is put inside the tube sample in which the artificial flow is to be made. The tube sample with the indentor inside it is attached to the hardness motor plate and lifted up until it touches the indentor. A predetermined force value is applied to the indentor and the sample is removed from the stand. The indentation dimensions are controlled using a projection system. In order to obtain the calibration curve a series of indentations is made at increasing load values. Bul.42/ 15.11.81.

Patent DE-3048188-A1 (DE)
Title: Ultrasonic test head with matrix of columnar transducers - giving reduced acoustic impedance and enhanced emission amplitude
Inventor: SACHS BERTRAM
IPC: B06B1/06
Filed: 1980-12-19
Abstract: An ultrasonic test head has at least one ultrasonic oscillator associated with a forward path for non-destructive testing. Thermal stability is achieved for ultrasonic angled test heads and ultrasonic transmission-reception test heads and is combined with improved emission of ultrasound. The ultrasonic oscillator is in the form of transducer elements whose height in the direction of transmission is greater than their width. The elements are column-shaped and arranged in a matrix (16). A better match between the oscillator and the forward transmission path is achieved because of the reduced acoustic impedance associated with finely distributed transducer elements. This results in a lower reflection and increased signal amplitude.

Title: Drawer extension device
Inventor: FULTERER MANFRED
IPC: A47B88/493
Filed: 1981-01-20
Abstract: The drawer guide has on both sides a support rail (1) on the carcass side and a guide rail (33). This guide rail (33) is supported by roller bodies (4, 5, 6) which are mounted in a spacer (7) preferably with radial clearance. The length of the spacer (7) is only a fraction of the length of the rails (1 and 33). A stop (13) on the support rail (1) prevents the spacer (7) being extended completely when the drawer is pulled out. In order to retain the spacer (7) in its front position when the guide rail (33) has been completely removed from the drawer guide, a latch (12) is arranged on the spacer (7), which latch engages in a locking member (19) of the stop (13), specifically under the effect of a spring-mounted tab (18). <IMAGE>
