Patent DE-2735024-A1 (DE)
Title: Audiometer for measuring hearing levels - has tone generator with switchable frequency and level and suppression method for spurious harmonics
Inventor: KOLLBACH DIETBERT DIPL ING
IPC: A61B5/12
Filed: 1977-08-03
Abstract: The tone generator is for testing bearing levels and has switchable frequencies and levels, the suppression of spurious harmonics during switching being achieved by changing the frequency or level in a practically continuous fashion as the output waveform passes through zero. The frequency or level is changed in sufficiently small steps by electronic switches (MOS transistors) controlling paralleled capacitors or resistors. Switching is controlled by a comparator supplied with a signal representing the generator output, and a signal representing the switching command, the comparator then giving an output at a zero transition. The waveforms may be digitally synthesised.

Title: Tunnel kiln for baking ceramic prods. - where gases leaving cooling zone are blown into preheating zone of kiln
Inventor: TSCHERNJAEV LEONARD I
IPC: F27B9/10
Filed: 1977-08-03
Abstract: The prods. are stacked on kiln cars travelling through a preheating zone; baking zone; and a cooling zone. Gases in the cooling zone are drawn into a high pressure blower and are then blown through nozzles in the walls and roof of the preheating zone (a). The nozzles are located in rows along the longitudinal axis of the kiln. The gases flowing through the nozzles leave the preheating zone via pipes connected to the suction side of the nozzles so gas circulation is achieved in the preheating zone. The productivity of the kiln is increased 25-30% and the specific fuel consumption is reduced by 10-15%.

Title: Crucible free semiconductor crystal pulling - with short circuiting ring and loop for local heat concentration
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/20
Filed: 1978-03-20
Abstract: The polycrystalline semiconductor (silicon) stock is fused in a crucible-less zone melting process to produce a single crystal by an induction heater coil of smaller inside diameter than the stock bar. Within the edge of the fusion zone of the stock, a local high gradient of the coil field is produced, for example by a water-cooled short-circuited ring with a small upward loop. The stock bar is rotated during the fusion process. This intensifies the heating action near the loop and melts any barbs which may be formed when the stock diameter is large. It ensures a uniform fusion process.
Patent DE-2813444-A1 (DE)
Title: Controller for three=phase water or underfloor heater - uses only one power circuit in one phase line while another line has relay
Inventor: GERHARDT ROLF
IPC: G05F1/66
Filed: 1978-03-29
Abstract: The controller limits the power delivered from 0 to 100% using a power regulating circuit in only one phase line. One of the remaining two phase lines contains a relay. The power regulating circuit may consist of two anti-parallel thyristors controlled by comparing actual current with a reference value representing the wanted load current (wanted power). The advantage lies in not having to employ a power circuit for each phase. Cost is thereby reduced and material saved. The controller is also smaller.

Title: Playing card shuffling machine - has cards moved from top or bottom of pack then divided into sections gripped by jaws.
Inventor: GOERN WALTER
IPC: A63F1/12
Filed: 1978-04-15
Abstract: The playing card shuffling machine has the cards arranged in a position in which the upper and/or lower side of the pack is free. Cards are then removed from the pack being taken either from the upper and/or the lower side. The cards removed are then conveyed in a flow having more than one layer. The flow of playing cards is then divided into separate sections of a width which largely corresponds to the measurements of one card in the direction of movement of the conveyor flow. The separate sections are then stacked. The playing cards are held by two clamping jaws (112) facing each other made as lockable and fixable rollers.
Patent DE-2820614-A1 (DE)
Title: Planar semiconductor device - with sloping edges of mask window for diffusion layer of higher breakdown strength
Inventor: REINDL KLAUS DIPL ING
IPC: H01L21/033
Filed: 1978-05-11
Abstract: A planar semiconductor device is produced by applying on an n-type substrate a diffusion mask with a window through which a p-type dopant is diffused to produce pn-junction. The mask edges which bound the window are given a gentle slope by differential etching. The result is a much greater radius of curvature of the diffusion layer so that the breakdown voltage of the pn-junction is much increased.

Title: Housing for meteorological recording instruments - has column with fan-assisted circulation starting from inlets on edge of roof
Inventor: KOHLENBERG FRIEDRICH DIPL ING
IPC: G01W1/14
Filed: 1978-08-01
Abstract: The instrument housing consists of a column-like structure with internal trunking through which atmospheric air is driven by a motor-driven fan. Air is sucked into the column, which is fitted with recording instruments, via inlets on the edge of the roof. The underside of the roof is fitted with an insect screen. The air drawn down the trunking passes out into the body of the column and out through a venturi nozzle. Air within the roof space warned by the sun's rays is not allowed to accumulate. Rain and precipitation is collected by peripheral channels and by a collector surrounding the outlet nozzle. The collected fluid falls into a funnel used in conjunction with a rain gauge.

Title: Composite sports shoe sole with curved cross=sectional profile - has abrasion-resistant solid rubber walking ply and padding ply, both plies being selectively sectioned along the sole edges
Inventor: EGGERS HERMANN
IPC: A43B13/14
Filed: 1978-08-23
Abstract: Curved full-length shoe sole, esp. for sports footwear, has an abrasion-resistant, pref. non-porous, rubber running ply, topped by a firmly bonded, also full-length, padding ply.

Title: Piston ring for large IC engine - has wear-resistant cast iron surface layer covered by chromium-plating
Inventor: BEYER HORST DR ING
IPC: F16J9/26
Filed: 1978-12-06
Abstract: The piston ring pref. made of cast iron has a wear-resistant bearing surface formed of two layers. It is treated to form a surface layer, rich in ledeburite, after which an outer layer of chromium-plating is applied. The surface cast iron layer has the structure converted to a ledeburite rich structure by subjecting the cast iron to localised melting in this zone. Pref. after melting the surface zone the piston ring is contacted with a quenching plate to promote the formation of the required microstructure.

Title: Surface treatment for PCB providing additional coating on wiring - roughens surface microscopically by mechanical process with chalk cover followed by deposit
Inventor: NOWAK EBERHARD
IPC: H05K3/24
Filed: 1978-12-27
Abstract: The surface treatment process is for printed circuit boards where the printed wiring is coated with an additional metallic layer such as nickel. All the edges of the printed wiring will then be covered with a protective coating. The metallisation is produced by a chemical process. The conducting surface, which is to be coated with a subsequent metallic layer is microscopically roughened by a mechanical process. It is then treated with solids containing chalk, followed by the deposit of the metallic layer. A second metallic layer, such as gold, is also applied by a chemical process. the treatment improved the corrosion resistance of the board and makes it amenable to brazing.

Title: Dishwasher with program for lightly soiled articles - eliminates special cleaning cycle to reduce water and running costs
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: A47L15/00
Filed: 1979-03-24
Abstract: For cleaning the lightly soiled items e.g. glasses etc. a certain amount of water is supplied to the wash container where it is heated up and mixed with a clear rinse agent. After circulation the liq. is pumped away and the dishes dried. When cleaning only lightly soiled items the cleaning cycle can be dispensed with which considerably reduces the running costs and water consumption since the intermediate rinsing programmes for diluting the cleaning agent are not required. If soft water heated to 40 to 50 degrees Cis used the heat retained by the dishes at the end is sufficient to dry them.
