Patent DE-3108631-A1 (DE)
Title: Teapot with strainer insert
Inventor: GROLMAN TASSILO VON
IPC: A47J31/02
Filed: 1981-03-06
Abstract: The invention is in the sphere of household implements, namely the implements for preparing tea. In this case, the technical problem consists in ensuring complete and intensive contact of the tea leaves with the water by unimpeded expansion of the tea leaves when drawing, but, at the same time, in making it possible to easily remove the tea leaves after the desired drawing time. The known teapots with a strainer at the spout require the tea to be poured after the drawing time. Due to their narrow shape and the fact that they have too few holes, the known teapots which have a strainer insert made of glass and other materials do not permit the tea to unfold in an unimpeded manner when swelling or sufficient tea extract to escape into the water. As a solution to the technical problem, it is proposed according to the invention to provide the teapot with a removable strainer insert which widens continuously from its lower end to its opening at the top, is composed of close-meshed wire mesh or finely perforated metal, glass, porcelain or plastic and is preferably matched, with its largest diameter, to the opening of the pot. As an advantageous embodiment for the teapot a shape is proposed which tapers continuously from the top downwards, the upper opening corresponding to its largest internal diameter. <IMAGE>

Patent DE-3149836-A1 (DE)
Title: Mixing valve
Inventor: BEHRENBERG ROLF
IPC: F16K11/065
Filed: 1981-12-16
Abstract: In this valve, which is suitable especially for metering the mixture and quantity of hot water and cold water, a disc is provided as the valve device parallel to the centre axis, which disc can be moved by an actuating element and rests against two discs which are held in a fixed position in the valve and are each provided with an inlet opening and an outlet opening. The quantity and mixture are controlled by a perforation which is constructed in the disc, together with the inlet openings in the discs, while the outlet openings in each valve position are covered by the perforation. An axial displacement of the disc results in a synchronous change in the flow cross-sections in the region of the two inlet openings and is used to determine the total flow quantity. Twisting of the disc about a rotation point in the foot of the sleeve results in one inlet opening being increasingly covered and the other inlet opening being correspondingly opened, so that the mixture ratio is varied without changing the total flow quantity. Tongues can be provided in the region of the perforation and of the inlet openings, as the covering means.

Title: Manufacturing method and apparatus for the continuous casting of round hollow billets with a rolling mandrel and an internal rolling method
Inventor: SCHWARZ GERHARD E
IPC: B22D11/00
Filed: 1981-12-21
Abstract: The invention is an apparatus and describes a method for the continuous casting of high-quality hollow round steel billets or tubes. The hollow steel billets are cast in a high-output continuous casting installation of low overall height. The continuous casting machine has a rotating mandrel for the internal cooling and hardening of the solidified steel. The rotating motion of the mandrel is hypocycloidal. The external cooling of the hollow strand is by a water-cooled mould and spraying, normally used in continuous casting installations. The regulated rolling speed of the mandrel controls the uniform removal of heat from the inner ring of the hollow casting and the dimensional change and rate of dimensional change of the cast steel. The hollow strands cast in accordance with this method have a truly round inside diameter and a smooth internal surface, which is a prerequisite for further processing to give finished tubes of high quality in conventional high-production installations.
