Patent DE-2626300-A1 (DE)
Title: Preventing oxidation of molten metal - with layer of sized globules of inorganic material coated with soft metal film
Inventor: SATO KOZO
IPC: C22B9/00
Filed: 1976-06-11
Abstract: The oxidation of molten metal held in a bath is prevented by depositing a granular compsn. onto the molten metal to separate the metal from the atmosphere. The compsn. consists of amixt. of relatively coarse, medium and fine granules 0.5-0.05 mm. in size. Each globule has a core made up of powdered glass, diatom and aluminium oxide coated with Al or iron oxides. A surface active agent and a binder are also present in the core material. The partitioning layer formed over the molten metal has a depth of 3 - 5 cm. Used for prevention of oxidn. of metals, esp. Pb, Zn, Sn, using material which does not disperse under thermal effect, eliminates pollution and is safer for workers than using organic materials.

Title: Shallow depth well drilling machine - has casing placed into borehole and holding non-return valve and pump
Inventor: BIELACZEK HERBERT
IPC: E21B7/26
Filed: 1976-07-14
Abstract: This well is drilled for obtaining ground water from the upper water conducting strata down to a depth of about ten metres. The water is drawn by manually or motor operated pump. The well is drilled by highly economical arrangement and the well is placed reliably and it is not blocked by sand. Ground samples are collected by a probe until, pref. an optimum, water carrying stratum is located. A well tube is sunk with the aid of the probe hole by rotation into the water carrying stratum. A pumping element with nonreturn valve is lowered into the casing tube. The upper part has conventional water drawing or closing element or an element for mounting a pump.

Title: Control arrangement for steam generator - has interacting control circuits for temp., pressure etc. operating as optimising loop
Inventor: BORSI LADISLAUS DR
IPC: F22B35/06
Filed: 1976-10-25
Abstract: The overall control system is in the form of a dual variable control, the first one being "steam output" and the second "steam quality". The first variable that is adjusted is "heat output". This is determined by the fuel mass flow and the mass flow of the combustion air. The second variable that is adjusted is "feed water flow". The working control (F) with the two branches providing the input values can be created as a decoupling control. The main control is then to be regarded as a single loop through which steam temp. etc. is optimised.
Patent DE-2649348-A1 (DE)
Title: Monitor for vehicle lights - has switching circuit and time delay to operate warning signal after ignition is switched off
IPC: B60Q5/00
Filed: 1976-10-29
Abstract: The lighting circuit is coupled to the ignition switch in such a way as to switch off the main beam when the ignition is switched off. If the parking lights remain on then a warning tone is generated after a set time delay. The warning tone is cancelled if the ignition is switched on again, or if the light switch is switched off. The protection circuit can also be extended to cover other circuits which are not cancelled with the ignition switch. Momentary cancelling of the light switch prevents the warning tone so that the driver can set the lights for parking.
Patent DE-2654146-A1 (DE)
Title: Automatic check system for central processors and peripherals - operates with coordinate identification device using reduced number of AND=gates
Inventor: LOEWER HARTMUT
IPC: H04M3/24
Filed: 1976-11-30
Abstract: The test circuit for central processing units comprises address buses (x, y) in conjunction with individual line indicators (Ix, Iy) connected to registers (Rx, Ry). The registers are connected to OR-gates (OX, OY). These are connected to an AND-gate (UXY) which gives an output signal when address data arrives simultaneously at its inputs. Energizing level sent from the peripheral units to the CPU (ZE) initiates a check routine whereby the energizing level is suppressed by a negative voltage on one line (x). The test unit (PG) then identifies which of the coordinates carried the energizing potential. The system requires only one AND-gate in the switching logic for all m x n addresses.
Patent DE-2736606-A1 (DE)
Title: Slipstream deflector for windscreen wiper - is mounted on separate arm to wiper arm and guided by rollers on windscreen

Title: Scraping treatment for leather hides - eliminates unpleasant manual labour and improves utilisation of scraping machine
Inventor: GABELMANN ERICH
IPC: C14B17/06
Filed: 1977-09-08
Abstract: The scraping treatment involves bringing a hide from a supply station, inserting about half the length of the hide between the open tools of a scraping machine, closing the tools and drawing out the hide which scrapes the first half. The hide is then reversed and the untreated half inserted into the scraping machine for treatment. The half-treated hide is now returned to a waiting station upstream of the scrapping machine and pref. alongside the supply station. The scraping machine is then fed alternately with a fresh hide from the supply station and a reversed, half-treated hide from the waiting station. Hides sent forward from both the supply and waiting stations to the scraping machine are pref. suspended by hook attachment of trolley of an overhead runway conveyor. The runway is pref. a closed circuit track so that a trolley can move around from the rear of the scraping machine back to the supply station.

Title: IC engine spark plug voltage tester with flashing indicator - has conductor on cable insulation, forming capacitor with cable core and being in electric contact with tester and operator
Inventor: STALZER MARIO
IPC: F02P17/12
Filed: 1978-02-28
Abstract: The electric power required for the operation of the flashing voltage tester is obtained by securing a conductive element on the insulation of the ignition cable. The conductive element is secured to the cable permanently, or during the testing only. This element forms with the cable core a capacitor and is also connected to the voltage tester and to the person carrying out the test. The slight electric energy is rectified and accumulated. When the energy has reached the ignition voltage for a glow lamp, the capacitor is discharged across this lamp. The discharge frequency is determined by the ignition voltage and frequency.

Patent DE-2846143-A1 (DE)
Title: Vertically adjustable column for swivel office chairs - has effective lowering movement using friction clamp and coil springs
Inventor: FRANKE EDGAR
IPC: A47C3/28
Filed: 1978-10-23
Abstract: The moving tube of the column is axially displaceable in a spring tube and can be braced by a clamping unit. This unit has a clamping sleeve which produces a friction connection with the sleeve by radially splaying out as it moves into the clamping position in which it stands permanently under the axial load of a pre-stressed spring which causes this radial expansion. To lower the tube with a damping effect caused by friction the friction connection can be partly released by a partial manual compensation of this load. The degree of damping can be determined e.g. according to the weight of the occupant if the swivel movement of the release lever is kept at variable amount through adjustable stops.

Thus, each rotor pole tooth has a depression in the central part under the ring with orifices, and the peripheral part of the tooth is provided with an edge that protrudes into the container tank cavity, the inner edge of the latter being designed in the form of a rebound shield. A labyrinth seal is arranged in the vicinity of the screen between the rotor and stator.
Patent DE-2852850-A1 (DE)
Inventor: ZIEGENFUSS JOCHEN DIPL ING
IPC: B28B7/36
Filed: 1978-12-07
Abstract: The process serves for producing fibre-reinforced, cement-bound pipes having a diameter/wall thickness ratio from 10:1 to 10:0.1, by spinning. In this process, a layer of paraffin or the like is applied to the inside surface of the spinning mould. A concrete layer with 3-10% by weight of added fibre is then introduced into the spinning mould thus pretreated. The layer of paraffin is applied in a layer thickness in which it acts as a water vapour barrier. Immediately after the introduction of the concrete layer, still before the start of the setting process, a corrosion protection layer and/or wear protection layer acting as a water vapour barrier is finally applied. This process makes it possible not only to achieve optimum strength values but, at the same time, to obtain pipes protected against corrosion and/or wear.
