Patent DE-4120269-A1 (DE)
Title: Inverted converter for lead circuit contg. discharge lamp - contains bistable switching device with bimetallic changeover switch contg. switching, rest and working contacts
Inventor: KROENING ARMIN
IPC: H05B41/285
Filed: 1991-06-19
Abstract: The inverted converter has at least two alternately and periodically switching switches connected in series to an intermediate circuit voltage. One is connected between the load circuit and a d.c. source and the other is parallel to a load circuit. A bistable switch connected to the load circuit switches off if a discharge lamp (LL) in the load circuit does not ignite, thus interrupting the ignition process. The bistable switch is a bimetallic changeover device (BMU) with switching (SK), rest (RK) and working contacts (AK). The rest contact is in a series resonant circuit (Lx, Cx). The bimetallic switching contact heats up during the ignition process and changes to the working contact position if ignition fails. The working contact is in series with a heatable discharge lamp electrode (HW) in a circuit which holds the switch in the working position. ADVANTAGE - Has bistable switch with minimum number of electrical and electronic components and minimal production costs.
Patent DE-4125330-A1 (DE)
Inventor: SEITER WOLFGANG DR
IPC: B01J20/18
Filed: 1991-07-31
Abstract: The aim of the invention is to provide a process for the production of dense granular zeolites, the amount of granulation liquid used representing less than the critical amount already known in the art, thus enabling (co)polymeric carboxylates to be used as the dissolved constituent of the granulation liquid. In the process proposed, granular materials consisting of a zeolite and sodium or potassium salts of polymeric or copolymeric carboxylic acids, with a bulk density of 750 to 1000 g/l, are produced by granulation with the addition of a granulation liquid, part of the zeolite being added in spray-dried form and at least 90 % of the zeolite particles having a diameter of between 50 and 700  mu m, and the granulation liquid containing a mixture of water, zeolite and (co)polymeric carboxylates.
Patent DE-4129830-A1 (DE)
Inventor: WIEDEMANN KURT
IPC: H04H20/00
Filed: 1991-09-07
Abstract: The invention relates to a multiantenna VHF receiver, the RF signal received by each antenna being mixed in a mixing stage assigned to the respective antenna with a signal of a first oscillator, generated in the receiver, and the mixed signals thus obtained, with controllable phase position, being added to form an aggregate signal. The alternative frequencies supplied by an RDS demodulator are stored. One of the mixing stages is used briefly at predetermined points in time for updating the stored frequencies with the associated values for the level of reception quality. If they fall below a predetermined level of reception quality, the receiver switches over to a stored alternative frequency which is accepted as suitable for reception. <IMAGE>

Patent DE-4216040-A1 (DE)
Inventor: LAMM HUBERT DIPL ING
IPC: H02H6/00
Filed: 1992-05-15
Abstract: A process is disclosed for monitoring an electric motor for thermal overloading in order to generate a switching off signal that switches off the motor when an admissible temperature limit is exceeded. In order to keep low the technical expenditure and the required total volume of an overload protector working according to this process, the motor power loss or a value proportional thereto is calcutated then integrated while the electric motor is switched on. The integration value is compared with a predetermined limit value and when the limit value (S1) is reached or exceeded the motor switching off signal is generated.

Title: Food packaging e.g. for prepd. meals - comprises containers held within outer container with reclosable gas-tight cover and thick oxygen@- and/or steam-tight walls
Inventor: STUERZER FRANZ
IPC: B65D77/04
Filed: 1992-07-01
Abstract: Packaging that (a) the prod. is in an inner container of suitable mono-layer material closed by an identical, high-purity material; and (b) a no. of such containers are placed in an outer container which has relatively thick 02- and/or steam-tight walls and a reclosable gas-tight cover. The outer container is pref. of (i) polypropylene, opt. provided with a barrier layer; or (ii) corrugated paperboard with a barrier layer. USE/ADVANTAGE - Useful for preprepd. meals, but can also be used for dehydrated or fresh foods. It has the required gas tightness while being re-usable or at least recyclable. Packages with a residual 02 content of 3% show a rise after 1 year to only 8%, this rise in 02 content being even less if the outer container has a barrier layer. In an example, polypropylene packages sealed with polypropylene film were sparged with inert gas within a 7 mm thick polypropylene container with a gas-tight cover so as to give a residual 02 content of ca. 1%.
Patent DE-4228698-A1 (DE)
Inventor: NEUMANN RODOLFO J PROF DR ING
IPC: F26B21/02
Filed: 1992-08-28
Abstract: Condensation drying of timber planks 7 is carried out by passing only a small proportion of the circulating air (or, alternatively, super-heated steam) used for drying, over the evaporator 1 of a heat pump. All the air is driven over the condenser 2 of the heat pump to be re-heated before entry to the stack, the air passed over the evaporator 1 being by-passed from the main stream and returned to it before the condenser 2 or to the main stream without passing over the condenser 2. Baffles 9 constrain the air to a circuitous path through the stack, and part of the condenser 2 may extend into the path for re-heating the air. A fan may drive the by-passed air over the evaporator 1. An auxiliary dehumidifier or air-outlet and -inlet dampers may be used for regulating the temperature of the super-heated steam or air. <IMAGE>

Patent DE-4238249-A1 (DE)
Inventor: MEIER JAQUES
IPC: B41B5/08
Filed: 1992-11-12
Abstract: The stitching heads (5) which, in a stitching region (C), interact with the supports (2) of a collecting drum (1) supporting the printed products which are to be stitched run along a circular peripheral track. In this arrangement, the stitching heads (5) are guided so that, during the revolution, they retain their substantially perpendicular position. This means that the stitching heads (5) in the stitching region (C) are approximately oriented with the associated support (2), which means that the staples can be driven into the printed product in the most favourable position. The stitching heads (5), on contact with the supports (2), are forced back counter to the action of compression springs (10). As a result, the circumferential track of the stitching heads (5) in the stitching region (C) is somewhat flattened, so that the time during which the stitching heads (5) can interact with the supports (2) for the stitching process is somewhat lengthened. <IMAGE>
Patent DE-4243222-A1 (DE)
Inventor: LANGE KLAUS-ULRICH DIPL ING
IPC: B65H29/68
Filed: 1992-12-19
Abstract: In order to slow down the transport of folded products in a satisfactory manner, for instance before entry into a second longitudinal folding apparatus, two groups of belts 1, 2 each containing upper and lower belts are integrated with a group of belts 12 containing only upper belts 11. Belts 11 run slightly slower than the first group 3 and are guided parallel to the belts 4 with a spacing between belts 11 and 4 which is greater than the spacing between belts 3 and 4. This arrangement helps to prevent the folded products being caught in the gap between the first, i.e. faster, and second, slower, groups of belts 1, 2. <IMAGE>

Title: Efficient steam-raising process for thermally operated power station - has additional water circulation for reclamation of latent heat of condensation to assist steam generation and eliminate cooling towers
Inventor: BRETTING EKKEHARD B DIPL ING
IPC: F01K17/00
Filed: 1992-12-22
Abstract: The modified process generates steam in a low-pressure vessel and is raised to working pressure by a multi-stage compressor with separate dedicated drive. The reclaimed thermal energy is circulated via a heat pump to assist the steam-raising in the low-pressure vessel and the complete system constitutes a closed circuit without cooling towers. The single turbine steps works up until the wet steam curve where it will again be over heated. USE/ADVANTAGE - Is applicable to stations employing coal, gas, oil or atomic primary energy and re-uses the working fluid i.e. water without the need for cooling towers exhausting to atmosphere. Is capable of improved operating efficiency as compared with contemporary practice.
