Patent DE-3407542-A1 (DE)
Title: Industrial furnace
Inventor: LOECHER ERNST-OTTO
IPC: F27D99/00
Filed: 1984-03-01
Abstract: Industrial furnaces for heating or heat-treating workpieces have a furnace chamber serving to receive the workpieces, a multiplicity of fuel-fired burners for direct heating of the furnace chamber and a recuperation device for preheating the combustion air flowing to the burners with the aid of the hot exhaust gases withdrawn from the furnace. In order to increase the efficiency of the industrial furnace and to ensure perfect control of the furnace atmosphere, a separate recuperator (15) is arranged upstream of each individual burner (3) or individual burner group and an air control valve (17) is provided in the cold air line (11) upstream of each recuperator (15), by which the cold air flow rate to be fed to each burner (3) can be adjusted. As a result of the multiplicity of the relatively small recuperators, a more favourable heat utilisation is possible and, in addition, the flow rate of combustion air per unit of time can always be held exactly constant independently of the degree of preheating. <IMAGE>
Patent DE-3411687-A1 (DE)
Inventor: DREXLER JOHANN ING GRAD
IPC: H01H1/20
Filed: 1984-03-29
Abstract: A contact arrangement for switchgear with multiple disconnects by contact points connected in parallel of two contact bridges aligned in a contact actuation link uses a spring collar for a contact pressure spring. The spring collar has cutouts transverse to the spring-action direction into which the contact bridges with the spring collars can be inserted and locked in place transverse to their longitudinal direction. The spring collar is rounded at two facing sliding surfaces in the contact actuation link aligned transverse to the longitudinal direction of the contact bridges. This assures optimal fitting of the contact bridges to the fixed contact components without jamming the spring collar in the alignment.

Patent DE-3417783-A1 (DE)
Title: Rigging
Inventor: REITER ALBERT
IPC: B63H9/06
Filed: 1984-05-14
Abstract: In conventional sails, the desired wing shape is determined merely by the wind forces together with the cut of the sail and the tension of the leech. Consequently, the optimum profile shape no longer occurs in the limit region and thus nor does the maximum propulsion achievable in the limit regions. The invention specifies a sail rib which can be put onto the sail. The curvature of the sail rib is adjustable and, together with a mast of symmetric profile shape, results in a virtually ideal, adjustable sail profile. <IMAGE>

Title: Method for transmitting information additionally to digitally coded sound signals
Inventor: HESSENMUELLER HORST DIPL ING
IPC: H04H20/81
Filed: 1984-12-13
Abstract: Information is to be transmitted additionally to sound signals digitally coded in blocks of in each case 64 samples of 14 bits each and one parity bit each without increasing the bit rate requirement because of this. It is known to transmit the scale factor, allocated to each block and consisting of three bits in each case, by logical combination with the parity bits. According to the invention, the additional information is also to be transmitted by logical combination with the parity bits. This is done by the parity bits P, allocated to samples 1 to 21, transmitting the scale factor SKF repeated 7 times and by the parity bits allocated to samples 25 to 64 transmitting the additional information in the form of a byte which is transmitted as data sequence ZD repeated five times, the additional information resulting in a data rate of 4 kbit/s. For the logical combination of scale factor and additional information with the parity bits, each logical 1 leaves the associated parity bit unchanged whilst each logical 0 inverts this parity bit. In addition to the program-accompanying data, the additional information also contains the necessary block synchronisation information (Figure 1). <IMAGE>

Title: Internal combustion engine with reduced noise and heat emission
Inventor: ELSBETT LUDWIG ING GRAD
IPC: F02F7/00
Filed: 1985-03-08
Abstract: This relates to an internal combustion engine with reduced noise, heat and pollutant emissions. In this, optimisation of the characteristics of an oil-cooled engine calls for heat dissipation by the oil, uniformly distributed on the entire circumference of the cylinder. For this reason a piston bottom part was developed which distributes the internal oil-cooling uniformly on the circumference. The external cooling was improved in that isolated cylinders are provided with a cooling-oil guide annularly recessed on the entire circumference and that the isolated cylinders stand in a common chamber cooled by splash oil. The more uniform this cooling on the entire cylinder circumference, the higher the possible temperature level of the cylinder, which is extremely important for the combustion of vegetable oils in place of petroleum products. At the same time the present design is aimed at improving the power density and running behaviour of the diesel engine so that its disadvantages compared to the spark ignition engine are largely compensated for.
Patent DE-3509538-A1 (DE)
Title: Dewatering of moist material by means of a roller press
Inventor: BLECKMANN HUGO DR
IPC: B30B9/20
Filed: 1985-03-16
Abstract: The invention relates to a process for dewatering moist material by means of a roller press and to equipment required for carrying out the process. In a known roller press, complicated and expensive additional units such as pumps and a pressure tank are required. The known equipment is, however, unsuitable for the dewatering of non-pumpable moist material, in particular wet bulk materials. The invention allows simple and uncomplicated dewatering of moist material in such a way that the latter is introduced from above into the roller nip, compacted and/or comminuted as well as dewatered therein, the dewatered material being taken off downwards and, separately from this, the expelled water being discharged towards the side in the longitudinal direction of the roller nip. In the roller press according to the invention, partitions (20) which project into the roller nip are arranged in the shaft (12) for charging the material. Below the partitions (20), water-receiving funnels (14) are located, which project from below into the roller nip and have discharge pipes (15). <IMAGE>

Title: Process for the preparation of water-dilutable paint binders
Inventor: DWORAK GERT DR
IPC: C09D167/00
Filed: 1985-04-22
Abstract: The invention relates to a process for the preparation of water-dilutable (water-thinnable), air-drying and oven-drying paint (surface coating, lacquer, varnish) binders by partial condensation of water-insoluble polyhydroxyl compounds with polycarboxyl compounds which are water-soluble after partial neutralisation. The crosslinking component for oven-drying paints is preferably a water-compatible amino resin. Partial condensation in the presence of the polycarboxyl compound significantly improves the stability of the aqueous solution of the system or the water-resistance and weathering resistance of the crosslinked paint films.
Patent DE-3519977-A1 (DE)
Title: Magnetic rotation motor
Inventor: WASKIEWICZ MARIAN
IPC: H02K16/00
Filed: 1985-06-04
Abstract: The previously known electromagnetic rotation motors are distinguished by a relatively large power consumption, rapid exhaustion of the electrical energy from the sources, and high construction and yield costs because of the large weight of the batteries required. These defects are overcome according to the invention by up to 50% in that round permanent magnets 2 having gearwheels 3 (which are mounted on them and are placed freely on shafts 4 which are mounted in the housing 1) are accommodated in the housing 1, on its circumference. Accommodated centrally in between the permanent magnets 2 is a permanent magnet 5 which is coupled to all the permanent magnets 2 by the gearwheels 6. Accommodated between the permanent magnets 2, on the circumference, are electromagnets 7 which are connected to an electronic control system. The central magnet 5 having the gearwheel 6 is placed on a driveshaft 8 which is passed to the exterior of the housing 1. This design makes it possible for a state of unstable balance to exist between all constant magnetic fields, which unstable balance is disturbed when the current is switched on in a continuous manner. This flowing current is approximately 50% lower because it is necessary only to generate a supplementary magnetic field. <IMAGE>

Title: Cross-flow blower
Inventor: BAYER ROBERT
IPC: F04D29/056
Filed: 1985-10-24
Abstract: The invention relates to a cross-flow blower with specially designed side walls. The side walls of the new cross-flow blower are made of a special plastic and connected to the air-guide plate and to the swirl-forming plate using ultrasonic welding technology. Integrated into both side walls is the bearing for the fan drum and, by means of a special shaping, a 2 - 3 slot arrangement, which revolves around the bearing, the fan drum is aligned radially and axially and the vibrations are damped. The major prerequisite, namely that of producing a flexible zone, is satisfied. The economic significance of the invention is obvious since, as can be seen from the attached drawings, up to four parts are omitted (rubber diaphragms, aluminium pot, porous bearing, oil supply disc). As a result of the ultrasonic welding technology already mentioned above, there is no longer anything to oppose use of plastic in the embodiment of the housing side walls, with which it is also brought about that the acoustic behaviour and the noise development of the cross-flow blower improve considerably.
