Title: Conductive path end region for soldering to semiconductor element - consists of narrow insertable section for terminal contact with adjacent wide reservoir section
Inventor: LEIBFRIED WOLFGANG DIPL PHYS D
IPC: H01L21/60
Filed: 1977-02-05
Abstract: The conductive path end region is intended for a hybrid circuit, and serves for soldering of a semiconductor element (5) according to reflow solder process in flip-chip technique. The end region consists of a narrow, finger-shaped inserting region (2b) for the terminal contact of the semiconductor element and an adjacent wider reservoir region (2a) for the excessive molten solder. The width of the reservoir region, between the inserting region and the conductive path proper (2), is about three times that of the finger-shaped inserting region. Typically the latter is 0.2 mm wide and 0.6 mm long, while the reservoir region is a square of 0.6 mm. The conductive path is 0.3 mm wide.

Title: Injection-moulding of plastics foam profile core with solid skin - by positioning it with spacers in the mould and injection-coating it
Inventor: PETERS HEINRICH JOSEF
IPC: A46B5/00
Filed: 1977-02-05
Abstract: Mfr. of plastics injection-mouldings comprises positioning a plastics foam profile in an injection-mould, with the aid of spacers, in such a way that it is spaced away from the mould cavity wall on all sides, and then injecting moulding cpd. into the mould so as to coat the foam core. the foam core and/or the skin-forming moulding cpd. are polyethylene, polypropylene or polystyrene. Used esp. for mfr. of components for household articles such as broom heads, scrubbing brush backs. Moulding with relatively thick solid skin enclosing sa foam core are obtd., the skin being free of voids and surface blemishes. The prods. have low tendency to shrink whlst the moulding cpd. sets, hence good dimensional stability is ensureD.

Title: Meat storage and dispensing unit - has storage trays with bottom extractors one for each quality of meat
Inventor: NIEDERBERGER HEINRICH
IPC: A22C18/00
Filed: 1977-02-18
Abstract: The appts. comprises a unit consisting of a horizontal conveyor onto which previously sorted pieces of meat all of one quality are deposited, and a scraper which removes the pieces from the discharge end of the conveyor and drops them into a storage tray below having a sheet metal bottom. An extractor, esp. a conveyor, removes the lowest layer of meat from this storage tray through an outlet slit at the end. Used for receiving meat directly from a slaughter house and dispensing it again on the 'first in first out' principle. The method ensures that the pieces of meat are all used correctly in turn and obviates the stacking of large quantities one above another, followed by removal of the newest piece from the top.

Title: Diode matrix memory with fail=safe facility - allows read-write operation with retention of contents until AC voltage signal is applied
Inventor: WALTHER DIETER HERMANN ING GRA
IPC: G11C17/14
Filed: 1977-03-26
Abstract: A matrix of selenium rectifier diodes operates as a read-write random access memory with a fail safe facility in the event of power loss. The information is entered by activating a row with a specific d.c. voltage level. Read out is accomplished by application of a second voltage. If the power supply fails the stored contents are maintained. The contents of the memory are erased by application of an a.c. voltage signal.

Title: Automatic resistance welding jig. esp. for relay springs - has worn electrodes rapidly replaced from storage magazine
Inventor: HAHN HELMUTH
IPC: B23K11/31
Filed: 1977-08-24
Abstract: The jig has an upper welding head consisting of a pair of tongs which rapidly clamp an electrode bar. A vertically driven plunger can drive the bar downwards into a removable holder. A new bar can be moved horizontally from a storage magazine until the new car is coaxial with the tongs. The plunger then pushes the new bar into the tongs. The bar is pref. round, with a conical taper on its bottom end adjacent to the workpiece, which is placed on a stationary, lower electrode with a large surface. The tongs are pref. spring-loaded, and can be raised so the holder can be driven horizontally to receive the electrode bar being replaced. Used in the mass prodn. of small parts, e.g. relay springs, where two welds can be made simultaneously, but electrode wear is rapid. The jig permits rapid replacement of worn electrodes, so there is min. loss of prodn. time.

Title: Insulated multiple glazing with variable optical effect - has venetian and/or spring roller blinds in spaces between panes
Inventor: HERMKES HUBERT PROF DIPL PHYS
IPC: E06B9/24
Filed: 1977-11-04
Abstract: The insulating glazing, which may be double or multipaned, has one or more venetian blinds and/or roller blinds fitted in one or more intervening spaces between panes. The slats in these may have smooth metal surfaces, or may be coated to increase the reflection of visible and/or infra-red light. There may be a coating on the interior side with a high degree of infra-red permeability, and on the exterior with a high degree of visible and near-infra-red light permeability. This provides a greater range of variability of optic effect for sun-screening and heat-insulating multiple glazing.
Patent DE-2749508-A1 (DE)
Title: Tank for liq. cooled transformers - has each cooling element in side walls closed against tank inner space by strips over entire height, to form channels
Inventor: HEIMFRIED ALBERT
IPC: H01F27/12
Filed: 1977-11-04
Abstract: The side walls of the tank are folded from sheet metal and contain a series of cooling elements. Each such element is closed almost over its entire height by a strip (3) against the tank inner space (1). Simultaneously it forms an orthogonal channel, connected on top and bottom by horizontal channels to the tank inside. The horizontal channels have a greater inside width than the orthogonal channel due to embossed notches (5) transversely to the edges of the folded sheet metal. Preferably the inside width of the horizontal channels is twice that of the orthogonal one. Additional strips may divide the cooling elements into several orthogonal channels for parallel partial flows.

Title: Infinitely variable gear transmission - has conical pinions on axes inclined to shaft carrying slidable ball-toothed pinion
Inventor: WODARKA EWALD
IPC: F16H3/42
Filed: 1978-02-10
Abstract: The gear has an infinitely adjustable ratio with a pinion fitted between two opposing wheels divided into an even number of equal sectors. Teeth profile grooves are so arranged that the pinion only engages with the teeth of one sector and the shafts of the wheels revolving at the same speed are connected for drive purposes via gearwheels. To vary the conversion ratio, the pinion and wheels are displaceable relatively to each other. The wheels (1, 2) are conical the surfaces of which have alternating toothed sectors (3, 4, 5, 6) and their surface lines facing the pinion (16) running in the planes of the pinion and cone wheel shafts (18, 7, 8) parallel to the pinion shaft (18).

Title: Arc welding burner for MIG or TIG welding - includes switch on burner handle locked in off position to ensure safety of operator
Inventor: AUER RUPERT
IPC: B23K9/29
Filed: 1978-02-23
Abstract: The burner uses either a consumable or a non-consumable electrode, and the handle is fitted with a switch for supplying or stopping the welding current, gas, and possibly the coolant and electrode feeds. The switch can be locked in the 'off' position, due to a sliding element on the push botton used to operate the switch. The pref. switch is a spring-switch with a lever (a) pressed inwards to turn the switch on, but the sliding element (b) can be moved along the push button so the element rests on the burner handle and prevents the switch being moved inwards to the 'on' position. Assembly work can be carried out on the burner, e.g. changing a nozzle, without danger to the operator caused by accidental movement of the switch to the on position.
Patent DE-2815033-A1 (DE)
Title: Light level control for battery-driven flashing lamp - has astable multivibrator increasing ON time of lamp when battery voltage is low
Inventor: KLAAS WILFRIED
IPC: H05B39/09
Filed: 1978-04-07
Abstract: The light level controls the integrated light level emitted by a flashing lamp depending on the voltage across the lamp supply battery. The lamp flashing is controlled by a clock generator whose ON time is shorter when the battery voltage is high and longer when the battery voltage is low. The battery voltage is compared with a reference voltage produced by a zener diode (V3). The basic clock generator consists of an astable multivibrator (V1) driving the switch (V6) that flashes the lamp on and off. The multivibrator has an RC timing circuit (R6, C2) and is connected to a pulse width modulator (V4).
