Title: Counterflow cooling tower for steam plant - has cooling cells below spray tubes, with sloping sided channels alternating with open zones
Inventor: REGEHR ULRICH DR ING
IPC: F28C1/02
Filed: 1980-08-12
Abstract: The counterflow cooling tower particularly for a steam power plant, has a chamber with bottom inlets (8) through which steam laden air enters, to travel upwards through a chimney (9) at the top. As the air travels upwards, it travels through a cooling cell system combined with horizontal tubes (6,7) from which water sprays are discharged. At right angles to the tubes are flow passages which alternate with short channels with sloping sides (12) forming the tops of the cells (2). Each short channel is under a spray pipe (6) and parallel to it, and alternates with an open topped cell (11) under the next pipe (7). The cells can also be arranged in an alternative manner.

Title: Sterilising packaging material with conc. ortho-phosphoric acid - pref. by passing through phosphoric acid bath and then removing residue
Inventor: BUCHNER NORBERT PROF DR
IPC: B65B55/10
Filed: 1980-10-18
Abstract: Packaging material is sterilised with 40-85% conc. H3PO4 at 30-80 deg. C, e.g. for 10-20 secs. Pref. containers are sterilised before filling with germ-free material and sealing. Packaging materials are sterilised before shaping to containers to filled with germ-free materials and sealed. Sterilisation can be achieved by passing the packaging materials through an H3PO4-contg. bath. Containers can be immersed, filled and then emptied or sprayed with H3PO4. H3PO4 residues are subsequently removed, pref. by blowing with sterile air or by suction. H3PO4 has a high germicidal activity, e.g. against B. subtilis and stearothermophilus; is odourless; does not vapourise under the conditions of use and acts as a food-acid.

Title: Covered railway goods wagon - has roof and walls in two sections with one section able to slide over other
Inventor: LOHMANN HEINZ
IPC: B61D39/00
Filed: 1980-11-03
Abstract: The railway goods wagon has its roof and sidewalls made in two sections. The roof and sidewalls of one section are linked together so that the roof can be raised and the walls pushed outwards to enable this one section to slide over the other section and so facilitate loading and unloading. The upper edge of each sidewall is attached to the roof by pivoted links which can be rotated by the levers (11,12). The lower edges of the sidewalls are supported on a short arms projecting from a tube (4). When this tube is rotated the lower edge is swung outwards.

Title: Self-service sales device
Inventor: MUELLER HANS
IPC: A47F3/02
Filed: 1981-05-11
Abstract: The invention relates to a self-service sales device for items of food, in particular pressure-sensitive and unpackaged loaves of bread. In known sales devices, it has previously not been possible to rule out the fact that customers touch the product or that the items of food come to rest on one another. Additionally, handling these known sales devices was cumbersome. According to the invention, the sales device consists of an elongate compartment with a shelf formed by a conveyor belt, on which the items of food lie in a row. The conveyor belt is driven by a motor which is actuated automatically by a switching device in such a way that one item of food in each case is located behind the removal opening ready for access to the customer.

IPC: H02J9/06
Filed: 1981-07-16
Abstract: In the case of an emergency power supply unit (standby power supply unit) according to the Main Patent 3033034 for an AC load, a connection (9) for an alternator (AC generator) (10), a battery (5) which can be recharged by rectified current from the alternator (10), a controllable reversible converter (double-way converter) (6) which is connected between said battery and a load connection (2), an AC voltage regulator (13) which stabilises the AC voltage on the AC voltage side (3) of the reversible converter (6) by pulse width modulation, and a battery voltage regulator (12) are provided. The alternator (10) can be connected in parallel on the AC voltage side of the reversible converter (6), and a current limiting resistor (8) is connected between the AC voltage side (3) of the reversible converter (6) and the alternator connection (9). In order to achieve DC isolation (DC decoupling) between the reversible converter and the alternator, and between the load (1) and the alternator (10), the current limiting resistor is configured as a high-reactance transformer (high-leakage-reactance transformer) (8') having three windings. One (31) of these windings is connected directly to the AC voltage side (3) of the reversible converter, the second (32) is connected to the alternator connections (9, 9a), and the third is connected to load connections (2, 2a). The high-reactance transformer not only produces DC isolation but, because of its parasitic inductances, at the same time produces the required current limiting.   <IMAGE>

Abstract: Whereas the basic application P 3124029.1 deals with displacing support arms in machines such as concrete pumps, vehicle cranes, etc. with respect to one another by means of a frictionally locking connection by pinion/chain or gear wheel/rack, the application of addition proposes to adjust an adjustable support arm in a guide profile by a friction wheel drive. For this purpose, the outer supporting roller is designed at the same time as a driving friction roller (6), is mounted on the guide profile (1) and is driven by a drive motor (13). It acts directly on the bottom flange (14) of the support arm (2) to be adjusted. The further development of the patent application relates to design details of the driving friction roller (6) in conjunction with the drive motor (13) and the mounting (12). <IMAGE>

Filed: 1981-11-14
Abstract: A screw mixer for bulk materials is proposed, having a feed hopper and a feed trough as well as a conveying screw arranged therein and extending into a discharge tube, as well as a vibration generator. In this arrangement, the discharge tube is to have at least one inlet for added materials, in particular liquids, and the conveying screw is to be designed with a core in the region of the filling trough. The region of the discharge tube adjoining the inlet is designed as a mixing region, in which the screw is formed without a core, in order to create space for the added volume. This may be followed by a compacting region, in which the screw is again provided with a core. It is also possible to provide a plurality of inlets for adding different materials, with associated mixing region and, if appropriate, compacting region.

Patent DE-3204503-A1 (DE)
Title: Hollow permanent magnet arrangement
Inventor: BYSTRICAN IVAN
IPC: H01F7/02
Filed: 1982-02-10
Abstract: The invention relates to an arrangement consisting of a plurality of permanent magnets (e.g. a spherical shape) which externally form a uniform magnetic pole over the entire surface. This magnet arrangement is intended in particular for various toys, models for planetaria and contact-free magnetic bearings. Figure 1 shows the hollow permanent magnet arrangement in a spherical shape which consists of four identical parts whose inner surfaces form a magnetic north pole while the outer surfaces form a south pole. The entire wall of this magnet arrangement is provided with a plurality of holes (3) which are used for the magnetic lines of force (B) to pass through. All the parts are bonded together. Figure 2 shows the hollow permanent magnet arrangement hovering above a permanent magnet ring (4) whose south pole is provided with an iron ring (5) with inclined inner surface. Since the surface of the hollow permanent magnet arrangement (1) has the same magnetic polarity as the lower permanent magnet ring (4) (electromagnet), the two permanent magnet bodies repel. The permanent magnet arrangement can hover and rotate freely in all directions. The hole (6) is used for fixing the hovering permanent magnet over the centre of the lower magnet ring (4). The gravitational force (A) is used for the same purpose. <IMAGE>
