Patent DE-2928574-A1 (DE)
Inventor: MUEHLE MANFRED
IPC: F16S3/02
Filed: 1979-07-14
Abstract: In a method for the production of thermally insulated composite sections a free space (4) formed between at least two metal sections (1,2), held spaced apart, and sealed at the bottom is filled from its open side with an insulating material (10) which at first is in liquid form and then hardens. In order to produce such sections, particularly also those of large size, with the least possible expense for labor and material, and at the same time to achieve the most favorable heat insulation values in the insulating region, solid insulating material layers (12,13) positively and frictionally joining together the metal sections (1,2), and insulating layers (14) hardening with a porous structure are introduced in succession into the free space (4), each layer only partly filling the free space. The introduction of the solid insulating material layers (12,13) and of the insulating layers (14) is expediently effected with the aid of a plurality of inlet nozzles (16, 17, 18) whose actions are chronologically staggered and which are disposed one behind the other in the working direction (19) of the filling operation, and for the porous insulating layers (14) the same material can be used as for the solid insulating material layers (12,13), a blowing agent which provides the porous insulating layers (14) with their porous structure being contained in the material in the case of the porous insulating layers (14).

Title: Pastry carrier - with section frame and tensioned wires for baking paper saves heat and baking time
Inventor: HAEFELE JOSEF
IPC: A21B3/15
Filed: 1979-12-01
Abstract: A pastry carrier is designed as a rectangular frame with profiled sections along the rim, with the opening filled up by parallel tensioned wires. This utilises the carrying capacity of the baking paper sheet insert (applied to catch the dripping brine and to keep it from the baking deck) so that the carrier is merely a frame for handling pastry and paper. The frame has side walls on three sides; the tensioned wires have a dia. of 0.75-1.0 mm and a spacing of 1 cm. The mass of the carrier is reduced and results in a substantial saving in heat and baking time in an accelerated baking cycle.

Title: Electric miniature motor with equi-spaced collector lamination - has recesses for retaining mixture of conductive particles with oily paste formed by bores extending towards adjacent laminations
Inventor: MABUCHI TAKAICHI
IPC: H01R39/04
Filed: 1979-12-10
Abstract: The collector laminations are fitted to an insulating cylinder, firmly mounted on a rotor shaft. Brushes form a sliding contact with these laminations. Recesses e.g. (5 - 1) retain a conductive mixture of fine conductive particles with an oily paste. They are provided by forming the bores in the insulating cylinder (2) such that each recess extends towards adjacent, or abutting, collector laminations. The conductive mixture is injected into the recesses so as to form a bridging of each collector lamination (3 - 1, 3 - 2, 3 - 3). An injected mixture provides the desired resistance circuits over the collector laminations. The recesses may be fitted at locations where the collector laminations and brushes are not coming into contact. The conductive mixture may have a resistance value of 1 to 500 times that of the rotor coils.

Patent DE-3023902-A1 (DE)
Title: Fibre suspension filter - has structured rotating cleaning heads to reduce pressure and volume surges
Inventor: STEINER KARL DR
IPC: D21D5/02
Filed: 1980-06-26
Abstract: The positioning of the filter cleaners opposite each other on the carrier, and the dimensions of the outlet for the cleaned fibre suspension, are so selected that while the cleaner assembly is rotating at least one or more cleaning heads are near the outlet opening. The outlet opening for the cleaned fibre suspension should approximate a hexagonal shape or a lozenge, as should the outlet for the evacuation of impurities cleaned out of the suspension by the unit. The filter mesh is mounted eccentrically in the vessel so that the circular gap between them is greater at the suspension outlet side of the unit. Designed to clean impurities out of a fibre suspension, the system gives a lower pressure and vol. surge as the cleaning heads rotate, so that it gives smoother running.

The horizontal rotor can rotate on a mast with the blades mounted vertically. Part of the surface (1) of the symmetrical wind-collecting blade (2) can deflect around the vertical axis. It has an adjustment element (5) on the rotor linked to the deflectable surface. The adjustment element can be adjusted against the action of a restoring force on the rotor as a result of the centrifugal force.

Title: Telephone with keyboard for number selection - which provides repeat facility for last number called by using reservoir capacitors
Inventor: BONO JEAN-CLAUDE
IPC: H04M1/31
Filed: 1980-07-30
Abstract: The instrument contains an MOS integrated circuit which is the pulse generator, memory, and control unit. The keyboard switches are only provided with sufficient contacts to give the required number information. In the connection to the telephone line is a high voltage transistor which is controlled by the integrated circuit to interrupt the loop current during number selection. Whilst speech is transmitted the transistor acts as a voltage regulator for the power supply to the peripheral circuits. The peripherals include reservoir capacitors which are charged during a connection,and which supply the small amount of power needed when the instrument is not in use. The peripherals include the short time storage of the number last selected, and may also incorporate an electronic block on trunk calls by suppressing transmission of an initial zero.

Title: Noise absorbing building facade cladding panels - have spacers providing intervals between overlapping units reducing sound reflection
Inventor: CONRADI JOHANNES PROF DIPL ING
IPC: E04F13/08
Filed: 1980-09-02
Abstract: Small panels for cladding external wall faces are shaped, arranged and fastened to as to reduce noise inside a building, and at the same time improve heat insulation and damp-proofing. In the area of vertical overlap they do not rest directly on top of each other but have space-retainers or similar to provide an acoustically effective interval, reducing the amount of sound reflected by the facade. They may have inclined perforations, without loss of protection from driving rain. A metal anchor can be enclosed in a shared elongated elastic tongue unit. Noise from traffic is significantly reduced indoors.

Inventor: SCHNEIDER WOLFGANG DIPL PHYS D
IPC: H01C17/07
Filed: 1980-09-22
Abstract: Foil resistors or networks of foil resistors are mass-produced from a foil of ductile metal (1) coated with a resistance layer (3) and are connected to an electrically insulating support (4). In the next stage (lower fig.) selective etching is carried out to produce a resistor or resistors (10) and contact surfaces (6) from the lti-layer foil.

In the second stage, the multi-layer foil is completely etched through to separate the various resistors together with their supports from one another. Specifically the multi-layer foil is deep-drawn and in the recesses the supports (4) are cast, the resistors are then etched in the bases of the structure and the multi-layer foil is cut along the side opposite to the resistors. Pref. the support material (4) is a casting resin, esp. glass fibre reinforced epoxy resin. The method is suitable for the mass prodn. of chip resistors of small size.

Title: Hybrid circuit including hybrid transformer windings - which are formed from conducting tracks, saving space on substrate
Inventor: BEUTIL HORST DR ING
IPC: H05K1/16
Filed: 1980-11-25
Abstract: The hybrid circuit consists of a substrate (Su) on which the fragments (F) are fixed between two conducting contact spots (KF1,KF2). These fragments (F) represent the lower halves of the windings of two magnet coils viz. primary winding and secondary winding of a hybrid transformer. The limbs (MKS1,MKS2) of the magnet core with inner opening (IS2/A/IS3) are so placed or fixed with an adhesive, that the magnetic field lines enclosing the inner opening when in operation, run parallel to the surface of the substrate (Su). In this case, one contact spot (KF1) lies on the side of one of the limbs (MKS1) of the magnet core, while the second contact spot (KF2) lies on the opposite side of the limb (MKS1). The rest of the windings are formed by sections (H) of conductor strips, fixed over the first limb (MKS1) as a metal layer on a carrier (IS2). Made in this way, the cost of winding hybrid coils by hand is cut out, lowering manufacturing costs.
