Title: Process and device for the continuous withdrawal of a pulverulent polymer
Inventor: ANDERS DIETMAR ING GRAD
IPC: B29C48/38
Filed: 1981-03-04
Abstract: A pulverulent polymer at a temperature of up to 90 DEG C produced in a gas-phase polymerisation process carried out under high pressure is to be withdrawn continuously and with strict avoidance of any contact with atmospheric oxygen. To this end, the pulverulent polymer is discharged continuously from a product separation tank into a plastication unit connected thereto in a pressure-tight manner, is plasticated, dammed up in the plastication unit, degassed and finally granulated. A device which is suitable for continuous withdrawal contains a pressure-tight connection of the exit opening of the product separator to an entry opening of a cylindrical plastication unit, in which a rotating screw with a pressure-consuming screw profile, is arranged and which is mounted and driven on one side and on the side facing away from the exit opening of the product separator. A granulation device is connected to the exit opening of the plastication unit. The process indicated and the device ensure continuous withdrawal of the pulverulent polymer, which is under high pressure, from the polymerisation system without any contact with atmospheric oxygen.
Patent DE-3109443-A1 (DE)
Title: Cooled PCM device for space heating and cooling by means of direct solar energy or indirect solar energy bound by water
Inventor: KLAMI PAAVO VEIKKO DR MED
IPC: F25B29/00
Filed: 1981-03-12
Abstract: According to the invention, in order to avoid heat losses use is made outside the heated space only of heat sources (heat stores) which are colder than the environment. Consequently, it is chiefly the heat dissipated during the phase change which is utilized, and the temperature is brought to a higher level by means of a heat pump. The evaporation of the primary working medium is performed directly in the heat sources, for example: heat from the icing of liquids, heat from boiling black liquid of the solar collectors, waste heat from the heating system itself, waste heat from the use of hot water, waste heat from air ventilation. The primary working medium is compressed in a common heat pump assembly. The costs of procuring and repairing the compressors are reduced by mechanical simplifications and a substantially lowered working pressure. The difference between the condensation temperature and evaporation temperature is reduced by means of larger evaporators and condensers. The compression work thus diminished is distributed over a plurality of small, identical, i.e. cost-effective compressors. The two or more working media are cooled before expansion at least down to the evaporation temperature, in order to prevent the harmful formation of gas. This waste heat is utilized in common with waste heat from all the devices.
Patent DE-3110075-A1 (DE)
Title: Current limiter for a switching regulator
Inventor: RAMBOLD KLAUS DIPL ING
IPC: H02M3/335
Filed: 1981-03-16
Abstract: The invention relates to a current limiter for a switching regulator. The transistor current of the transistor (TS) which is located in the primary circuit of a transformer (TR) is measured via a current transformer (SW) and is compared with a reference voltage which is dependent on the duty cycle of the transistor current. If the maximum permissible transistor current is exceeded, then the transistor is switched off until the start of a new switching period. Switching-off occurs virtually always at the same output current, even in the case of different input voltages to the switching regulator, as a result of the reference voltage which is dependent on the duty ratio. The limiter circuit (BS) contains a differential amplifier (DV) to which a measurement voltage (ui) which is proportional to the transistor current (iT), and a reference voltage (Uc) are supplied. The reference voltage is produced via a switch (S), which is controlled in accordance with the duty ratio, a resistor (R1) which is connected downstream of the switch, a voltage divider (R2, R3) and a capacitor (C) which is used for filtering. <IMAGE>

Patent DE-3117926-A1 (DE)
Title: Musical instrument, particularly an electronic organ
Inventor: ACHTNER GERHARD
IPC: G10H1/24
Filed: 1981-05-06
Abstract: A possibility is proposed to preprogram the tone colours in electronic musical instruments, particularly electronic organs, in order to be able to call up the individual preprogrammed tone colours quickly and without effort when playing the instrument. For this purpose, the analog actuator values of actuating elements to be operated manually, such as, for example, sine-wave pull bars, are converted into coded data signals and stored in a memory. The stored actuator values can be reliably and reproducibly read out by addressing the memory with the aid of a key panel, and used for controlling D/A converters which set tone signals. Instead of storing the data signals, these can be supplied directly to the associated D/A converters after completed generation. When already preprogrammed memories are used, the programming process can be omitted. <IMAGE>

Title: Electromotive adjustment device for headlights of motor vehicles
Inventor: BAUER PETER-JOSEF
IPC: B60Q1/076
Filed: 1981-05-12
Abstract: When a change in the spring compression of the body of a vehicle occurs, an electromotive adjustment device pivots the reflectors for dipped lights in an infinitely adjustable fashion into that position in which the dipped light beam does not exceed the prescribed range. The threaded bolt (100) of a push rod (138) interacts with a threaded sleeve (136) of a worm wheel (130). The latter has an external thread (32) which interacts with an internal thread (33) of a base body (34), which threads both run in opposite directions to the thread of the bolt (100) and of the sleeve (136). By virtue of the opposing directions of the two threads, an increase in the travel of the push rod (138) and consequently a corresponding increase in the pivot range of the reflector (16) is achieved with the same electrical control variables. <IMAGE>

Title: Method and arrangeement for positioning a device for ophthalmic examination
Inventor: BOUIS DIDIER DR
IPC: A61B3/113
Filed: 1981-06-19
Abstract: In ophthalmic examinations, in particular when measuring ocular movements, a problem arises as regards the exact positioning of the measurement device relative to the head or the eye of the person to be examined. Positioning is effected to date by means of trying and testing, in which respect, in the event of a measurement beam in the invisible range, it is possible only during or after the measurement to establish whether the position is correct. To solve the problem, the invention proposes that the visible light (4) from a light source (1) arranged on the optical site of a receiver (23) for an examination beam (22) be irradiated convergently onto the eye (5) and that the light beam reflected from the eye (5) be observed on the optical axis (3) of the device. <IMAGE>

Patent DE-3134878-A1 (DE)
Title: Catamaran surfboard
Inventor: MARKO MILAN
IPC: B63B35/79
Filed: 1981-09-03
Abstract: The known surfboard has several disadvantages such as, for example, easy overturning during use, and as a flat board it has corresponding water resistance, which reduces the speed during surfing. To eliminate these disadvantages, the surfboard according to the invention consists of two narrow floating bodies which are arranged next to one another at some distance apart and are connected to one another by a platform. The latter serves to accommodate the sail mast and serves as a base for the surfer to stand on. Due to the floating bodies spread wide apart, there is no easy tipping movement as in the known surfboards. The surfing mode is thus more varied and quicker, especially as the floating bodies have less water resistance. The surfboard is insensitive to waves and therefore the surfing mode is stable and safe.

Title: Shaft lining with a load-bearing, sliding inner lining cylinder
Inventor: LUETGENDORF HANS-OTTO PROF DR
IPC: E21D5/012
Filed: 1981-11-20
Abstract: A shaft lining (1) for lining deep shafts in unstable, water-bearing rock (2) has a water-tight, load-bearing, sliding inner lining cylinder (4) with an outer steel casing (8). The inner lining cylinder is arranged coaxially in an outer lining cylinder (3) and distanced from the latter by an annular gap (5) filled with a sliding fluid (5), for example soft asphalt. In order to obtain a light inner lining (4), which is thus as economical as possible, the sliding fluid (5) has a specific weight which increases with greater depth. The relatively low specific weight in the upper depth area permits a light inner lining (4), while the relatively high specific weight in the centre and lower depth area ensures the stability of the inner lining, which is heavier at this location. <IMAGE>
