Title: Mug glazing - has support for clamped mug to turn through 180 deg. to spray fluid glaze inside and outside
Inventor: STROEDER DIETHELM
IPC: B28B11/04
Filed: 1990-02-02
Abstract: To apply a glazing to mugs, and similar open vessels, each mug is placed on a support with the opening upwards and is held by a clamp.

Title: Sandstone anti-weathering treatment - by impregnation by immersion in mineral clay suspension
Inventor: HEINZE PETER DIPL ING
IPC: C04B41/50

Title: Phosphorus@ purificn. to give low sulphur content - by mixing with sulphuric acid, diluting to separate emulsion and immediately sepg. phosphorus@ and acid
Inventor: ZSCHALICH ARNDT DIPL CHEM
IPC: C01B25/04
Filed: 1991-11-16
Abstract: Redn. of the S content of P, after purificn. by intensive mixing of the P with H2SO4 and then sepg. the emulsion with water, is effected by sepg. the purified P and dil. H2SO4 immediately after sepn. of the emulsion. USE/ADVANTAGE - Reducing the contact time between P and dil. H2SO4 ensures that the S contennt is low, e.g. 50 ppm, making the P suitable for sensitive applications. In an example, 1000 kg/h P-contg. 2600 ppm oil and less than 20 ppm S and 100 kg/h H2SO4.H2O were mixed intensively at 60 deg.C., then the emulsion was passed into (A) dil., (B) very dil. H2SO4 in a packed column. Residual H2SO4 was removed by washing the P discharged from the column with a countercurrent stream of (A) 300 l/h (control), (B) 10 cu.m/h water at 70 deg.C.. The P was then stored under (A) dil. H2SO4, (B) water for 24 hrs., then transferred to a second vessel under hydrostatic pressure and (A) washed with 300 l/h water at 70 deg.C.. The purified P contained (A) 1150, (B) 180 ppm S and (A, B) 25 ppm oil. Variants of method (B) make it possible to reduce the S content to 25 ppm.

Title: ABS brake system using principle of volume expansion - has modulator with pistons between master cylinders and brakes, with pistons moved by electric motor
IPC: B60T8/36
Filed: 1991-12-05
Abstract: The ABS brake circuit for a car has a modulator cylinder interposed between the master cylinder and the two circuits for the wheel pairs. The modulator has a pair of pistons, one floating, one attached to a threaded rod. The threaded rod is rotated by gearing from an electric motor with axis parallel to the modulator. The pistons create extra volume for the fluid, namely between the pistons for one brake circuit and between one piston and the cylinder for the other circuit. Excitation of the motor can drive the pistons in either direction to reduce or increase the available volume, thereby giving respectively a temporary increase or decrease in brake pressure. ADVANTAGE - Compact design easily fitting into engine bay of any car. Electromagnetic valves integrated into modulator housing.
Patent DE-4200283-A1 (DE)
Title: Forming silicon@ wafers by spin-casting on rotating table - by forming melt of polycrystalline silicon@ granules and recrystallising using embedded seed-crystal
Inventor: GEYLING FRANZ T
IPC: C30B11/00
Filed: 1992-01-08
Abstract: A melt container (12), pref. made of quartz and formed in a U-shape, filled with molten Si (17) above which a container (11) for granular polycrystallne Si (14) is placed to replenish the melt. The melt container is heated (13) to form the melt (17) and maintain its temp. (19) near the opening (25), from which it is poured to form Si wafers. The exit opening (25) is pref at the opposite end of the container from the filler opening (11). The granules container (11) is pref. a drum, pref. made of quartz, which can be rotated and contains a slit opening (15) through which it can be filled and emptied when the drum is in an appropriate position. A friction-less coating is used between the drum and the filler-opening of the melt container to provide a hermetic seal and allow easy rotation of the drum. A gas-inlet opening (24) allows an inert gas ambient to be used to force the melt out of the opening (25) to pour the wafers. The process consists of forming a melt, which is held inside the container by the pressure of the ambient gas, and pouring it onto a spinning plate (30). A method for recrystallisation is also claimed. USE/ADVANTAGE - Faster formation of single crystalline Si wafers compared with the conventional Czochralski crystal bar pulling. Avoids lengthy wafer-cutting process currently used. The method allows very much purer polycrystalline Si to be used and causes much less contamination since it is used quickly as it is poured into the melt container. The recrsytallistion has been modified to minimise contamination of the wafers. Avoidance of wafer sawing also reduces Si waste.

Patent DE-4206658-A1 (DE)
Inventor: SEIDELBERGER HARTMUT DIPL ING
IPC: G21C9/004
Filed: 1992-03-03
Abstract: A temperature-dependent pressure discharge is provided for the case when the core is insufficiently cooled (very improbable failure of the cooling and emergency cooling arrangements). A pressure pipe (23) that extends in a pressure-tight manner through the wall (1b) of the pressure vessel (1) and that projects into the pressure vessel (1) has at least one pressure compensation opening (26) arranged in the inner space (24) of the pressure vessel and sealed by a fusible sealing body (25). The fusible sealing body (25) is a fusible solder which melts at a threshold temperature for example between 600 and 700  DEG C, unblocking the pressure compensation opening (26), but which keeps the pressure compensation opening (26) closed during normal operation. The pressure pipe (23) is in particular a blow-off pipe with a pressure discharge opening. The pressure pipe may also be, however, a pressure control pipe for controlling a blow-off valve provided outside of the vessel in order to reduce the pressure of the system.

Title: Cooling device for interior of car - has flap allowing fan to draw blow exterior or interior air past peltier cold generator in roof
Inventor: FUERST ARPAD
IPC: B60H1/00
Filed: 1992-03-07
Abstract: The cooling device has a solar-powered (or car battery-powered) "cold generator" (12) utilising the Peltier Effect, fans (18, 19) and a flap (22) to redirect the air flow. The device is located in the roof (10) of the car. One fan (18) draws outside air over the top of the Peltier generators which then produce a cold lower surface. If the interior temperature is already cooler than the outside, the inner fan just recirculates the inner air, this air being cooled by the Peltier generators. If the interior temperature is higher than the outside, the flap opens automatically, allowing the interior fan to suck in colder outside air. This is again cooled further by the Peltier generators. ADVANTAGE - Highly efficient temperature-dependent cooling device.
