Patent DE-3302792-A1 (DE)
Title: Process for preparing hot water by heat recovery from the refrigeration plant used for ice surface treatment in artificial ice-rinks
Inventor: SYKAMINIDIS JOANNIS DIPL ING
IPC: E01H4/02
Filed: 1983-01-28
Abstract: The superheat is taken out of the compressed refrigerant gases and transferred to water, which is heated to about 85-90 DEG C, situated in a storage container. This hot water is used for the periodic ice surface treatment of the artificial-rink by means of a special ice preparation machine. The hot water is brought to the desired temperature, as required, by the addition of fresh water by means of a mixing and regulating device, and is fed into the ice preparation machine, the high power cost incurred for heating 650 l/h of water in the ice preparation machine being saved.

Title: Voice recording and reproducing device
Inventor: HAENDLE MICHAEL
IPC: G11B31/00
Filed: 1983-02-12
Abstract: A voice recording and reproducing device, as already realised in fundamental aspects by, for example, conventional dictating machines with telephone connection, is made into a voice-processing device by the use of a plurality of sound carrier systems which can be operated independently of one another but also can be connected together for single re-recording operation. Thus, texts, recordings of conversations and telephone calls and the like which are available in voice form can be processed without having to rely on written notes, in particular can be processed purely in voice form for the purpose of adding data, necessary or expedient for understanding, concerning time, origin and intention of a recording, for the purpose of selecting particulars which can be used for a specific case and for the purpose of further additions, for instance for issuing instructions. Consequently, it is possible to dispense with much paperwork, in particular in the handling of information within a company. Electronic devices of this type are suitable for interaction with much other electronic workplace equipment.
Patent DE-3308264-A1 (DE)
Title: Apparatus for the suspension of a spray system
Inventor: KAFITZ WALTER
IPC: B03C3/86
Filed: 1983-03-09
Abstract: The invention relates to an apparatus for the suspension of a spray system of a vertical electrostatic precipitator, with a support column passing through an opening 18 of a housing roof 4. The support column also forms the current supply for the spray system and is carried on the housing roof 4 by means of an insulator. In known vertical electrostatic precipitators, a lead-in insulator was provided for the support column. Such a lead-in insulator is very greatly endangered by possible bending moments. Furthermore, coverings on such an insulator cause particular difficulties. It is therefore proposed that the vertical support column 16 is fastened at the upper end to a beam 20 which rests on at least two support insulators 22 arranged on the housing roof. <IMAGE>

Title: Smoke and heat outlet installation for flat roofs
Inventor: KREFT ULRICH
IPC: E04D13/035
Filed: 1983-05-26
Abstract: A smoke and heat outlet installation for flat roofs has an attachment ring and a cover fastened pivotably on the attachment ring. The plane of the upper outlet opening of the attachment ring runs at an angle, that is to say at an angle of approximately 10 DEG  to 30 DEG , to the horizontal, as a result of which an influencing of the vertically emerging smoke and/or air flow by side winds is to a great extent excluded. At the same time, plane covers, for example cavity panels made of plastics or glass panels, can be used, without rain and/or condensation water remaining on the cover.

Title: Process for regenerating potassium hydroxide solution in electrolytic wire cleaning
Inventor: SCHERER VOLKER DIPL CHEM DR
IPC: C25F1/08
Filed: 1983-07-13
Abstract: In a process for removing and recovering tungsten or molybdenum and for removing graphite from the potassium hydroxide bath in the electrolytic cleaning of tungsten or molybdenum wire, the contaminated hydroxide solution from the bath which the wire passes through is first passed through a mechanical filter to remove the graphite. Alkaline earth metal hydroxide in solid form, in particular barium or calcium hydroxide, is then added to the graphite-free solution to precipitate the tungstate or molybdate, the precipitation products are then filtered off and the purified, undiluted potassium hydroxide solution is returned to the cleaning bath. <IMAGE>

Patent DE-3334310-A1 (DE)
Inventor: WANG ANTHONY D
IPC: H03M1/06
Filed: 1983-09-22
Abstract: An integrated circuit digital to analog converter includes circuitry having first and second resistors in a R/2R resistor ladder which scales bit current contributions to an analog output current. Each of the first and second resistors have a respective terminal connected to the collector of a bit current transistor, the emitter of which is connected to the emitter of a waste current transistor. The digital to analog converter includes a metal ground voltage conductor having a "shared node" and a distributed resistance between one side of the shared node and a main ground voltage connection. The collector of the waste current transistor and a second terminal of the first resistor are both connected directly to the shared node. In operation, the waste current transistor switches waste current into the shared node, rather than into a separate waste current ground conductor. This results in substantially less voltage variation across the distributed resistance of the metal ground voltage conductor, and consequently lower non-linearity, than is the case if waste current is switched into the separate ground conductor.
Patent DE-3335876-A1 (DE)
Title: Process for joining at least two heating plates made of plastics by welding and heating plate for carrying out the process
IPC: B29C65/00
Filed: 1983-10-03
Abstract: A process for producing a plate assembly from a plurality of heating plates comprises producing the individual plates with respectively inclined welding surfaces, the wall end sections of adjacent heating plates being directed towards one another, containing the welding surfaces and having a complementary shape. After the heating of the welding surfaces to the required temperature a welding jig is inserted into the hollow space section to be produced by assembling the welding surfaces, which avoids a flowing-out of the softened plastics material in the region of the welding surfaces into the hollow space during the joining of the individual heating plates. The inclined arrangement of the welding surfaces leads to an enlargement of the welding surface itself compared with methods for butt welding and thus to a weld seam which is continuously welded over the entire wall thickness of the heating plate assembly.

Title: Device for the automatic quantity-oriented delivery of piece-goods
Inventor: OTULAK JOSEF
IPC: B65G47/10
Filed: 1983-11-21
Abstract: In order to deliver piece-goods in a quantity-oriented fashion directly from magazines, ordering devices or storage devices, for example continuous-flow shelving, a delivery device with a control system has been formed. The piece goods, whose technical magnitudes are variable in the technical limiting magnitudes of the delivery device, are drawn off and delivered one after the other and continuously from the feeding unit, for example a magazine. The quantity to be drawn off is input into the device in advance. If the devices are combined into blocks, even different kinds of piece goods assigned to the delivery devices are delivered independently of one another and simultaneously.
