Title: Carbonating process for waste liquors from cellulose mfr. - for sepg. hydrogen sulphide in following carbonate prodn. stage
Inventor: RAESAENEN REINO
IPC: D21C11/00
Filed: 1978-03-20
Abstract: Green liquor is treated with CO2 gas at a concn. of >50 vol.%, under increased pressure, to carbonate, and to remove the sulphur from the liquor in the form of H2S. The H2S is removed from the soln. in a process following that of carbonating, which is carried out in a mixing reactor. In this, the pressure applied is higher than the total counter pressure of the partial pressures of the CO2 and H2S in the green liquor soln. and the partial pressure of the stream. Used for the removal of H2S from solns. of alkaline sulphides in waste liquors arising from cellulose mfr. Release of H2S during the carbonating process, which makes the recovery of SO2 difficult, is prevented.

Title: Aromatic sulphonic acid prodn. - by sulphonation with sulphur tri:oxide in continuous circulation system
Inventor: LANDAUER FRANZ DR
IPC: C07C309/28
Filed: 1978-08-29
Abstract: Prodn. of aromatic sulphonic acids (I) from aromatic cpds. (II) and SO3 is carried out continuously in a circulation system at 30-140 degrees C.

Title: Hydraulic braking system for vehicle - has braking force distributed diagonally between two circuits, each having separate anti-wheel lock control
Inventor: KLAUE HERMANN DR ING
IPC: B60T8/44
Filed: 1979-05-16
Abstract: The hydraulic braking system distributes the braking force diagonally between the two braking circuits in the ratio 75:25 to 92:8 for braking forces above 0.55g. Each circuit has separate anti-wheel-lock control.

Title: Calibrating system for nickel phosphor thin film resistances - uses selectively applied heavy metal sulphate soln. as etching medium
Inventor: OSTWALD ROBERT DIPL CHEM DR IN
IPC: H01C17/24
Filed: 1979-06-29
Abstract: The method of calibrating nickel-phosphor thin film resistancers, uses an etching system, forming an improvement upon previous mechanical or laser beam systems. The conductor tracks embedded in the layer are not affected, by using a salt soln. applied in a selective manner. Soln. uses a heavy metal sulphate such as copper sulphate, iron or cobalt or manganese sulphate or nickel sulphate in demineralised water. The soln. can be applied by brushes with glass fibre filaments. The brush can be a rotary brush with the fibres parallel to the film surface. It can be applied by a grit blast, where glass pearls form the blast medium, matching the width of the area to treated.

Title: Key operated vehicle theft-prevention circuit - has resistive key in bridge circuit connected to discriminator in interrogation circuit
Inventor: KUEMMEL GUNTER ING GRAD
IPC: B60R25/20
Filed: 1979-07-23
Abstract: The anti-theft system for a vehicle uses a special resistance key (5) for a door lock, connected to an interrogation circuit (3). The key operates a conventional cylinder mechanism (2). The tip of the key closes a switch (6) controlling the interrogation circuit. The key carries resistances (7,8) which are connected by a set of contacts (9 to 14) to the interrogation circuit. This includes a bridge circuit (39) which is combined with a discriminator (25) so that in the event of an incorrect resistance being introduced into the bridge, an alarm activating signal is obtained at an output terminal (A). The window discriminator is interconnected with diodes (36, 37, 43, 44) for blocking peak voltages at two inputs (28,29). The interrogation circuit is also connected to a resistance capacity system with two capacitors (34,41) and two resistances (38,45) for blocking fault signals.
Patent DE-2933275-A1 (DE)
Title: Automatic accurate tobacco weigher - prevents over-weighing by separating coarse and fine tobacco particles and by adding fine particles to approach wt. from below
Inventor: GLOCKER HEINZ WALTER
IPC: G01G17/02
Filed: 1979-08-16
Abstract: The tobacco passes from a supply container along an inclined vibrating channel (5). The coarser tobacco particles pass via a grille (50) directly into a feed channel (10) and fill a metering or dosage chamber. The contents of this chamber are passed to the pan of a weighting device. Adjustable metering flaps (54) distribute the fine component of the tobacco over the central region (52) and side regions of a base (53) beneath the grille (50). Financial loss is reduced by approaching the wanted weight of the portion from below - adding fine tobacco particles gradually - instead of allowing the portion's weight to overshoot the wanted value. Repeated overweighing, from e.g. tobacco clumps is avoided.

Filed: 1979-11-05
Abstract: The resistance layer of this thick-film resistor has a first resistor part (T1), which is in the form of a film and has a resistance value R1, and a second resistor part (T2), which is in the form of a film and has a resistance value R2 which is less than that of the first resistor part (T1), the first resistor part (T1) being connected in series to the second resistor part (T2), via an intermediate resistor part (PCG) having the resistance value R3.
