Patent DE-2702641-A1 (DE)
Title: DC driven thickness gauge for magnetic materials - has linearised DC proportional output voltage independent of head gap
Inventor: GORTAT MANFRED ING GRAD
IPC: G01B7/06
Filed: 1977-01-22
Abstract: The thickness gauge for ferromagnetic material comprises a digital-analogue converter (1) which converts the required thickness into a proportional DC to control a current source (2). This latter drives the exciter coil of the measuring head (3). The saturation flux is measured by a Hall generator (4). The generator output is amplified and linearised (5, 6). The linearised output is proportional to the absolute thickness. This is subtracted from the set value (7) and the deviation obtained. As the excitation voltage is proportional to the air-gap between head and material, the corrected excitation voltage can be used to correct the Hall voltage so that the output voltage is independent of the air-gap dimension.

Title: Variable setting seat for construction vehicle - has motor drive for tilting to either side when moving along inclines
Inventor: LINDBLOM KARL THORE
IPC: B60N2/39
Filed: 1977-03-02
Abstract: The driver's seat of the construction vehicle can be tilted about a horizontal, longitudinal axis (8) so that the driver can assume an upright positon when driving along the sides of inclines. The seat shell is fitted with a semi-circular track (14) which is gripped by a friction servo clamp (18) to hold it in the selected position. The driver presses a control to release the friction servo and tilts the seat to suit his confort. On releasing the control the servo locks the seat setting. The system reduces backache and provides a safer control for the machine.
Patent DE-2713122-A1 (DE)
Title: Monitoring automatically or manually controlled trains - is for sectioned track and using linear signal transfer method enabling reference switching
Inventor: ZIMMER RUDOLF ING GRAD
IPC: B61L3/22
Filed: 1977-03-22
Abstract: The method is of monitoring automatically or manually driven trains on a track divided into sections, each section having a busy warning device driving a light signal at the beginning of the section and uses a signal transfer unit (SF) placed a distance before the signal (S3) determined by the permissible maximum speed and the braking time. The unit transmits track free or not free signals to trains where they are stored, indicated, and used to activate a speed-braking monitor system comparison involving a stored speed reference. Linear rather than pointwise transfer is employed to enable automatic use of the permissible maximum speed as the reference speed if the signal changes from not free to free.

Title: Capacitor or resistor with plate, rod or tube shaped ceramic body - has plastics sheath shrunk on to body and parts of leads by heating and sealed by sprayed, self-hardening material
Inventor: SACKL ALOIS
IPC: H01C1/034
Filed: 1977-06-07
Abstract: The capacitor or resistor has a disc, rod or tube ceramic body with a round or angular cross-section pref. a flattened tube section. It is provided with leads, of which at least one is on the outer surface of the body and has a protective sheath. The sheath consists of a plastics tube (4) shrunk onto the component (1) and onto part of its leads (2, 3). It is shrunk by heating, thus tightly surrounding the component and its leads. One or both of the openings of the tube may be closed by a self-hardening plastics material which can be sprayed on. The construction avoids the varying length sleeves of protective material on the connection leads which can hinder component soldering in p.c. boards.

Title: Flowmeter coping with contaminated media - measures pressure required to feed small constant flow to tapping holes
Inventor: TREIBER KARL-HEINZ DR ING
IPC: G01F1/20
Filed: 1978-06-27
Abstract: A flowmeter measures the volumetric flow of fluids and gases by using a gas dosing method in conjunction with a curved section. Accuracies of the order of 1.5% can be achieved with contaminated fluids. All significant measurement system components are mounted outside the tube and can therefore be protected from undesirable influences. A small constant flow of gas is fed into the pressure tapping holes and the pressure required to achieve this is measured. This gas flow prevents hole blockages cuased by contaminants.

(I) has a particle dia. of 1-1000 um, pore vol. of 0.3-3 cm3/g and surface area of 100-1000 m2/g. The supported catalyst makes it possible to reduce the mol. wt. of the polymer relatively strongly, even with relatively small amts. of H2 as regulator, which is esp. important in the dry phase polymerisation process. Polymers with esp. favourable morphological properties can be obtd.

Title: High-extensibility fabrics for medicated dressings - incorporate bulky stuffer threads to increase pore volume and reduce heat-loss
Inventor: SCHAEFER EWALD DIPL CHEM
IPC: D03D15/56
Filed: 1978-12-05
Abstract: Woven fabrics with high extensibility in warp or weft direction or both for use in the prodn. of adhesive medicated dressings, have extensible warp and weft threads of crepe yarns with counts of Nm 50/1, 40/1, 34/1 or similar, whereby Nm 50/1 yarns have a twist of 1750 turns per m, or crepe yarns of counts Nm 50/2, 40/2, 34/2, 70/2 or similar having 2150 turns per m in a count of Nm 50/2, alternating with non-extensible yarns of Nm 8/1, 10/1, 13/1 or similar to form a thick, voluminous textured surface. The extensible threads may alternatively consist of texturized synthetic filament material such as polyamide or polyester, or of covered polyurethane or rubber yarns. The fabric combines high extensibility, of 30-90%, which permits it to conform to body contours without restricting movement or comfort, with high pore volume, which reduces heat loss and promotes the healing process.

Title: Appts. for removing electrostatic charge - uses two discharge electrodes receiving AC potentials in opposite phase generated by HT transformers
Inventor: MUZ EDWIN DIPL PHYS DR ING
IPC: H05F3/04
Filed: 1979-01-23
Abstract: A device for removing electrostatic charge from goods moving at high speed past two or more de-electrifying elements with discharge electrodes connected to electrical alternating voltages uses economical circuitry and operates with a high degree of reliability and more efficiently than conventional devices.
