Patent DE-3823993-A1 (DE)
Title: Method for coordinate measurement on workpieces
Inventor: NEUMANN JOACHIM DIPL ING
IPC: G01B5/012
Filed: 1988-07-15
Abstract: The geometrical elements (51, 53) on the workpiece (50) which are to be measured are traced purely by a movement of the stylus (tracer, feeler) (19a) along the workpiece surface with the main carriage of the coordinate measuring machine at a standstill. For this purpose, the coordinate measuring machine has a probe with its own guide system and drives which move the stylus or feeler carrier in all three spatial directions in a frictionless fashion over a range of movement of at least 5 cm. A processor calculates the contact forces exerted on the workpiece from the difference between the thrust forces of the motors and the acceleration acting on the feeler carrier. <IMAGE>

Patent DE-3900809-A1 (DE)
Inventor: KNIPP HERBERT
IPC: B29C67/20
Filed: 1989-01-13
Abstract: Latex foam has been produced to date in metal moulds which are preferably heated with steam. In the case of deep moulds, the gelling and vulcanisation time is long; the process requires expensive apparatus and is not very economical in terms of energy. The latex foam is introduced into a mould of nonmetallic material, the temperature of which at the surface in contact with the latex foam can be between 45 DEG C and 100 DEG C, and the said foam is brought to a temperature of up to 100 DEG C in the course of 3 to 10 minutes by means of microwaves, the foam being vulcanised. Thick foam elements also have a very uniform pore structure and a uniform elongation at break. Production of latex foam in constant quality even in a thick layer under economical conditions.

Title: Electrically-heated flow-type water heater
Inventor: METZGER MANFRED
IPC: F24H9/20
Filed: 1989-03-03
Abstract: An electrically heated flow-type water heater has heating resistors (7, 9, 10, 11) arranged in star connection which are connected via switching contacts (4, 5 and 15) of a water switch to external conductors (1, 2, 3) of a three-phase grid (mains). For optionally switching on a partial load, a partial-load switch (6) is arranged in the circuit. So that these four heating resistors (7, 9, 10, 11) can be accommodated inside a heating block in a way which is as favourable and space-saving as possible, they are connected in a chain (16), connected to two external conductors (1 and 3), in such a manner that the externally located heating resistors (7 and 9) each emit the same power and double the power as the internally located heating resistors (10, 11) which likewise each emit the same power. The partial-load switch (6) forms the star point (20) of this chain (16) and bridges the internally located heating resistors (10, 11). <IMAGE>

Title: Control valve
Inventor: SATTELBERG MANFRED
IPC: F16K1/12
Filed: 1989-03-02
Abstract: The invention relates to a control valve, consisting of a substantially rotationally symmetrical outer housing and a likewise substantially rotationally symmetrical streamlined inner housing arranged centrically therein and connected to the outer housing via connecting webs, in the case of which control valve an annular space subdivided by the free connecting webs serves as flow passage between outer and inner housing, the cross-section of which flow passage can be reduced by an externally actuated valve member displaceable coaxially in the inner housing or can be closed by application of a seal, arranged in the valve member, against a corresponding sealing surface on the inside of the outer housing. In order to construct a control valve of the type described such that the working lives of the seals are considerably increased and hence the operating reliability substantially improved, it is proposed that at least that region of the valve member (3) which receives the seal (9) is withdrawn, in the opened end position of the valve, into the inner housing (2), in which case a sleeve (6) is arranged between the inner housing (2) and the seal (9), which seal is sealed off from both, coaxially surrounds the valve member (3) and, in all opened intermediate positions of the valve, retains its relative position to the valve member (3) and, in the closed end position of the valve member (3), is displaced counter to the closing direction in such a way that the seal (9) comes free towards the sealing surface (13) of the outer housing (1). <IMAGE>
