Title: Smell preventing disposal system for excrement - uses foam in bowl made by mixing foaming compounds with water
Inventor: BURMEISTER HANS
IPC: E03D9/00
Filed: 1975-06-25
Abstract: An arrangement for disposal of excretements in a lavatory bowl as in the main patent prevents spreading of disagreeable smell. A foam bolster is generated in the lavatory bowl by a suitable compound. This foam is removed together with the excretements on flushing with water. The foam forming compound is available as a tablet or an aerosol container. A refillable container can also be used. One part of the foam forming concentrate is mixed outside the lavatory bowl with water. This mixture will foam on shaking and the foam is pored into the lavatory bowl.

Title: Electronically controlled meter for heat quantities - uses Zener dioce or quartz crystal frequency as reference value and CMOS or switching circuits as electronic units
Inventor: SEIBT ARTUR DR ING
IPC: G01K17/16
Filed: 1976-04-28
Abstract: The meter has a self-contained current supply unit, which obtains from the tested medium electric energy necessary for the electronic equipment operation. CMOS units or bipolar switching circuits are used as electronic units, and stepping mechanism and/or drum counters are used as indicators. They are controlled by pulses. Counting pulses proportional to heat energy consumption are electronically stored when current supply is insufficient owing to low heat consumption. Voltage of a Zener diode or a frequency derived from a quartz crystal are used as reference value for calculation of the energy consumed. In order to reduce electric energy consumption, temp. sensors and electronic circuits are operated pulsewise.

Title: Stiffening for thin walled unstable structure - has stabilising super-pressure generated in sealed hollow spaces with height set by external tension cables
Inventor: FRITZ HELMUT DR
IPC: E04G21/12
Filed: 1976-10-14
Abstract: The process is for stiffening thin-walled and unstable structures and components, esp. of steel or reinforced or prestressed concrete as used in tanks, silos, pylons, cooling-towers and other civil engineering works. The hollow spaces (17) in these are closed, and the structure or component is then stiffened by generating superpressure in them, to exert a stabilising effect. Bulkheads may divide the hollow spaces into sections with varying pressure levels. The stems of slab beams or hollow box units may be made in hollow cross-sectioned form, for stiffening by superpressure. The structure may be raised by extending the tension members (16) with increase in pressure or lowered by shortening them.

Title: Pastry turning baskets - for solution application arranged on both sides of application box for charge and discharge
Inventor: MEINASS ULRICH
IPC: A21C9/04
Filed: 1977-02-26
Abstract: A salty or sugary soln. is applied to the surface of pretzels, rolls and crescents before the baking operation by inserting the baking tin with the pastry dough in a turning basket under a grid and by turning the basket. The grid with the pastry is pushed into a spraying or dipping box and is removed after application to a second turning basket where the reverse operations is carried out. The process is speeded up if the two turning baskets are arranged with the soln., application box between them. This enables a continuous flow prodn. to be maintained.

Title: Alloy contg. tin with antimony and copper - with zinc, aluminium and magnesium additions to improve workability
Inventor: SANDIG HARTMUT DIPL PHYS DR
IPC: C22C13/00
Filed: 1977-03-25
Abstract: Tin alloy contg. by wt. 0.1-7.0% Sb, 0.1-8.0% Cu, 0.5% max. Pb, 4% max. Ag. To improve workability in the mfr. of tinware or pewter, the alloy also contains 0.0045-0.45%, esp. 0.015-0.05% Zn, 0.0005-0.05%, esp. 0.001-0.005% Al, and 0.0001-0.01% esp. 0.0005-0.0025% Mg, the balance being tin. The tin alloy(a) contg. the Sb, Cu, Pb and Ag is pref. melted, and then 0.005-0.5% esp. 0.02-0.1% of a Zn-Al-Mg alloy(b) added. Alloy(b) pref. contains 0.5-10% Al, 0.1-8% Mg, balance fine zinc; and the esp. pref. compsn. of alloy(b) is 4.8-5.2% Al, 2.5-4% Mg, rest Zn. In the mfr. of pewter, the normal alloy(a) meets DIN 17810, but defects can arise such as microcracks or fissures in deep-drawing, flow-forming and other working operations. The addn. of Zn, Al and Mg prevent the segregation of the Cu6Sn5 phase, so a fine structure is obtd. in which the Cu6Sn5 consists of small spheroids instead of coarse needles. The coarse structure normally obtd. impairs workability and results in an uneven atack when pewter articles are pickled.

Filed: 1977-04-07
Abstract: The electric toaster has heating elements (8, 10) for toasting both sides of the bread at once and to this end are mounted above and below a horizontal support surface (12) for the bread. At the end of a predetermined period a time relay activates a transfer mechanism to move the toast to the collecting container (42) wherein this transfer mechanism comprises an ejector (19) which is biased by a spring (24) in the direction of a first position along the front of the support face in front of which is attached the collecting container (42). The ejector (19) can be moved manually from the first position to a second position along an opposing rear side of the support face and held in this latter position close above the support face (25, 26). The time relay (33) is set in operation when the ejector moves into the second position and releases the pawl mechanism at the end of its present period.
