Title: Screening appts. for lumpy difficult-to-sieve material - has flexible double mat with larger openings over vibrating sieve mat to prevent clogging
Inventor: HIRSCH WOLFRAM DIPL ING
IPC: B07B1/46
Filed: 1980-04-10

(I) can be used for the treatment of excess internal eye pressure. Sotalol reduces eye pressure by twice as much as Timolol does, and after 5 hrs. after application the effect due to sotalol is twice as much as that due to Timolol.

Title: Car seat hinge with rake and height adjustment - has separate gear drives in offset planes about single control lever on both its sides
Inventor: WAGENER HEINZ-JUERGEN
IPC: B60N2/235
Filed: 1980-06-25
Abstract: The rake and height adjustment of the car seat is obtained by using a single control lever (45) operating on a central lever mounting (42). This is linked to one of two ratchet gear drives, one each side of the central mounting in parallel planes. The hand control lever is operated in one of two directions to regulate either setting. The hinge control is compact and simple. One hinge section (21) operates on the height control, while the other one (26) sets the rake. A rapid release lever in the side of the seatback allows the seat to be tipped flat for access to the rear seats without loosing the rake setting. The two sides of the hinge mounting are linked by torsion springs.

Title: Telephone subscribers appts. signalling test procedure - using exchange registers to test signalling conditions from telephone dial or multifrequency sender
Inventor: SPRINGER NORBERT
IPC: H04M1/24
Filed: 1980-07-09
Abstract: A test programme is run in a stored programme control telephone exchange, esp. a p.b.x., in order to test the dial pulse or multi-frequency number output of the telephone subscriber's appts. The exchange comprises subs line terminating units (TS1...TSn) connected both to the switch block (KN) and the central common control and stores (St,ZSt). Also connected to the switch block are registers for receiving loop disconnect dialled pulses (WAS) and multi-frequency signals (IS) from the telephone or incoming trunks. By dialling a predetermined code the subscriber's appts. (T1... Tn) can be connected through to the appropriate register (WAS or IS) in a test mode by the common control (St,ZSt). Dialled or multi-frequency transmitted signals are verified by the equipment by transmitting audible tones back to the subscriber's appts.

Title: Two=stage mfr. of special low alloy steels - by induction melting dry charge and oxygen-inert gas refining of melt
Inventor: WINTERHAGER RUDIGER
IPC: C21C5/52
Filed: 1980-09-12
Abstract: Special constructional steels and tool steels, with an alloy content (apart from carbon and silicon) of max. 6%, are produced by melting a dry charge in an induction furnace (pref. a low frequency induction furnace), tapping off the slag-free melt, refining the melt by blowing with an oxygen/inert gas mixt. in the presence of a desulphurising agent, and then deoxidising and adjusting to the final analysis. High grade steels, e.g. contg. max. 0.015% S and max. 2.8 ppm H, can be produced in large batches e.g. of 20 tons. The use of a dry charge allows low hydrogen, low sulphur steels to be produced without vacuum treatment, and expensive electroslag remelting is not required. The resulting steels show improved notch impact properties after heat treatment.

The wear-resistant roller cladding is a number of ceramic rings to allow roller bending. The rings are ground together. The mountings for the roller segments have a ceramic cladding against the material, slightly lower than their neighbouring roller segments. The supports for the fourdrinier are at least partially displaced from each other to given even wear. The cladding has a width of 8-15 mm, while the roller segments are 50-120 cm wide, pref. 70-100 cm. The roller dia. is 40-70 mm, with at least partially spherical ceramic sliding bearings as the support, with lubricating passages giving an axial feed through the rings and the bearing.

Title: Rapid metallisation of (non)conductive substrate - by surface enrichment with base metal powder and immersion in more noble metal-contg. soln.
Inventor: GRUBER BRUNO
IPC: C23C18/18
Filed: 1980-10-29
Abstract: Electrically conductive or non-conductive substrate is metallised by enriching its surface with a base metal powder in amt. such that, in its dry state, the surface is non-conductive but becomes conductive a short time (pref. a few seconds) after immersion in an electrolyte and is rapidly metallised by the more noble metal dissolved in the electrolyte. The surface enrichment may be carried out by coating the surface with a lacquer contg. a suspension of the base metal powder or, when the substrate is made of a mouldable material, by mixing the base metal powder with the substrate material before hardening. The process is useful, e.g. for (selective) electrolytic or electroless Cu, Ag or Au plating, e.g. in the prodn. of printed circuits, musical toys and model construction kits and for electrical shielding of housings and devices made of different materials. The substrate is rapidly metallised without using expensive conductive silver pastes and metal parts can be plated (e.g. for rust protection) without any pretreatment.
Patent DE-3046636-A1 (DE)
Title: Demodulating channel coded data signal - using two demodulators with pulse signals in both phase positions and pilot circuit to select valid output
Inventor: SCHOLZ WERNER DIPL ING
IPC: H04L25/49
Filed: 1980-12-11
Abstract: The demodulating circuit is intended to give an output without sudden phase changes. The transmitted signal, after initial integration and frequency doubling, (2s bar) is applied to a phase locked loop (5) and flip-flop (6) to generate two timing impulse signals (T, T bar) in anti-phase. The processed signal (2S bar) is applied to one input of a pair of demodulators (7,8) whilst the timing pulse signals (T, T bar) are applied one to each demodulator. Of the resulting demodulated signals only one is correct. The two outputs are applied to a change over circuit (9) from which one output is applied to a pilot circuit (10). This checks the signal at its terminal and alters the change over circuit (9) to the state where the true signal (NRZ) arrives at the output terminal (2). B.

Title: Preheater for oil burners
Inventor: DORSCH HELMUT
IPC: F23K5/20
Filed: 1981-03-20
Abstract: The invention relates to a preheater for oil burners, especially for pressure pulverisers of low power. Preheaters of this type consist of a housing arranged between burner nozzle and oil pump, with conducting channels for feeding oil from the pump to the nozzle and with a preheating heating element, arranged therein, with temperature regulation for bringing about or maintaining a predetermined preheating temperature of the oil in the conducting channel, and of a thermostatically controlled cold-start interlock device for interrupting the supply of current to the pump drive as soon as the temperature of the oil in the preheater falls below a predetermined minimum value. In order to prevent an undesirable outflow of oil when the pump is stationary as a result of reheating by the heating element and heating of the oil to the desired temperature, there is provided, according to the invention, a valve device with a closing member (4) which, as seen in the oil throughflow direction, is arranged behind the heating element (7) in the oil-conducting channel (3a, 3b) and which, in the closing position, blocks the supply of oil to the nozzle, and with an actuating device for the closing member (4), which brings the latter into its closing position when the pump is stationary and which keeps it in this until the pump is (re)started after the predetermined preheating temperature is reached, at which moment it is brought into the open position. <IMAGE>
