Patent DE-2701064-A1 (DE)
Title: Ceramic glazes for decorative floor tiles - with high abrasion resistance, contain hydrothermally hardened aerated cement
Inventor: KOSCHLIG HANS JOACHIM DIPL ING
IPC: C03C8/04
Filed: 1977-01-12
Abstract: Ceramic glaze consists of glass formers, fluxes and possibly colorants or pigments and also contains 5-50 (10-35) wt. % hydrothermally hardened aerated cement. The aerated cement is produced by foaming a mixt. of chalk, cement, quartz sand and water followed by hardening in an autoclave. The SEGER formula for the glaze is: Li2O 0-0.1; Na2O 0-0.1; K2O 0-0.2; CaO 0.2-0.7; MgO 0.01-0.4; BaO 0-0.1; ZnO 0.05-0.6; PbO 0-0.2; Al2O3 0.15-0.4; Fe2O3 0-0.1; SiO2 0.8-2.0; ZrO2 0-0.4; TiO2 0-0.4. The hydrothermally hardened aerated cement is cheaper than Wollastonite which is usually used for this application. Aerated cement is readily available and is of uniform compsn. The high specific surface of the cement aids the reactions in forming the glaze.

Title: Wire cable twister - has sliding runners as guides displaced from rotary axis to allow high speed working
Inventor: HENRICH WERNER
IPC: D07B3/00
Filed: 1977-03-21
Abstract: In a rotary twister to twist wire strands left and right into a cable, sliding runners are provided, displaced from teh rotary axis, to guide the wire. The total angle which the wire strands pass round the runners is greater than or equal to 360 degrees, and the angle round each individual runner is 180 degrees or more. The runners are in sections to form a runner ring, joined together without gaps, with a V-shaped notch to guide the wires by forming a line of contact between the wire strand and the runner. The V-shaped notch is rounded at its base, with the side flanks opening out sufficiently to give an opening. Each runner can alternatively have a right-angled notch guide. The design prevents the effects of centrifugal and other forces from limiting the speed of operation, and allows the production of long unbroken stranded wire.

Title: Pendulum roller bearing sealing system - incorporates spring rings in grooves on both sides of outer roller race, limiting swing
Inventor: WILKE ARTHUR
IPC: F16C23/08
Filed: 1977-04-23
Abstract: The pendulum roller bearing has outer and inner rings, and at least one series of roller bodies between them, running in prepared races. The swivel movement of the outer ring is limited relative to the inner. Two spring rings (21, 22) are snapped into ring grooves (23, 24) on both sides of the outer race (10), but by projecting radially inwards they act as a stop for the roller bodies (3) when the maximum permissible swivel position of the outer ring (1) relative to the inner ring (4) is reached in both directions. The roller bodies are laterally sealed by discs (13, 14) fitted on the outer ring. These seal against the spherical surfaces (8, 9) on the shaped rings (6, 7) which are shrunk, screwed or stuck onto the inner ring (4).

Start and stop keys control the cycle and the amount of money involved is shown on a display.
Patent DE-2728309-A1 (DE)
Title: Fire alarm system with line voltage interruption for resetting - has circuits with different thresholds to detect operation of more than one alarm from different line currents
Inventor: STAHMER PETER
IPC: G08B17/00
Filed: 1977-06-23
Abstract: Electronic fire alarms (De, Dm) are connected across a line fed from a battery in series with a switch (18) and a line current measuring circuit (20). Actuation of an alarm (De) causes an increase in line current which in turn actuates a threshold circuit (24). The output of the threshold circuit momentarily interrupts the line current by opening the switch (18). The threshold circuit is also connected to an integrating circuit (40) whose output can actuate an alarm via a store (46). When one alarm has operated the output of the current measuring circuit is switched over by the alarm signal to a circuit (26) wiht a higher threshold. Operation of a second alarm can now be detected without disabling the first.

Title: DC control for electroplating - by multiplying workpiece surface area with desired current density and adjusting bath voltage
Inventor: HUEBEL EGON
IPC: G05F1/20
