Title: Temp.-dependent compensation circuit for oscillator - has voltage divider with parallel diode, with further, high-valve resistor in series
Inventor: WASSENER HANS-JOACHIM DIPL ING
IPC: H03L1/02
Filed: 1980-07-22
Abstract: The oscillator circuits are tuned by variable capacitance diodes. The compensation circuit comprises a voltage divider (R1,R2), at which the output tuning voltage (U2) for the capacitive diode (V1) is tapped. A diode (D1) is in parallel in the forward direction to the voltage divider. To this parallel connection is series connected a resistor (R3) of high-ohmic type w.r.t. the voltage divider resistors. The compensation circuit is supplied with the input tuning voltage (U1). Pref. the voltage divided is in parallel with a base-emitter paths of a bipolar transistor. To this transistor base is supplied the input tuning voltage, while its collector is coupled to a supply d.c. voltage source. The ratio of the divider total resistance to the high ohmic resistor is so chosen that the diode, or the transistor, are energised, starting from a defined threshold voltage, in order to make the temp. compensation effective. The oscillator is suitable for use in a UHF t.v. tuner.
Patent DE-3028832-A1 (DE)
Title: Preheated coal charging of coke ovens - by scraper conveyor filled with coal after each charging operation
Inventor: HABERMEHL DIETHARD DIPL PHYS D
IPC: C10B31/04
Filed: 1980-07-30
Abstract: A system for charging of coke oven chambers with preheated coking coal uses an endless scraper conveyor in an enclosed trough. After the completion of every charging operation, the conveyor is not stopped but continues to run until the entire trough is again filled with preheated coal. Pref. in the charging station, the level of the preheated coal is kept constant by a level control of the feed star wheel. An endless scraper chain conveyor takes the preheated coal to the breeches pipe with the shutters to fill the oven chambers. This ensures that all charging gases are displaced from the trough and no explosive mixtures can remain. The costly conventional flushing with inert gas before every charging operation is now saved.

Title: Heat insulating blind inside window - is foil sheet unrolled with magnetic strips gripping metal strip, creating air cushion
Inventor: SCHEUERER JAKOB
IPC: E06B9/24
Filed: 1980-11-12
Abstract: Loss of heat from indoors is checked by an insulating venetian blind designed for mounting on the inside of windows in heated buildings. Use is made of a roll-up foil sheet, to create a damming space on the inside of the window. Edges can be fastened by a metal strip in conjunction with welded magnetic strips.

Title: Multilayer sealable paper bag has inner lining sealed - while closure flap is folded back to expose layers to heat
Inventor: KUCKHERMANN GUSTAV
IPC: B29C65/00
Filed: 1980-12-06
Abstract: A method of sealing (welding) the inner lining of a multi-layer paper bag having a staggered closure flap comprises the following. The closure flap (4) fixed to the rear side of the paper bag is folded back about a fold line (5) set back (i.e. further down) from the edge (6) of the inner lining (3). While it is in this folded-back state, heat is applied to the exposed inner layer (3) to seal the superimposed layers together. The fold line (5) may lie virtually coincident with the edge (6). Infrared thermal energy may be used for the sealing, regulated as a function of the speed of passage of the bag. This method ensures better penetration of heat to the various thickness of paper than was possible without the folding back of the flap. Thus prodn. rates can be increased.

Title: Busbar system with busbars for high-voltage and medium-voltage systems
Inventor: KRAEMER WILHELM
IPC: H02G5/10
Filed: 1981-02-02
Abstract: A busbar system for high-voltage and medium-voltage systems with busbars (26) preferably of rectangular cross-section is characterised in that each of the busbars (26) is largely surrounded in the current-carrying region by at least one cooling body (31), which extends along the busbar and consists of thermally conducting material, and is connected in a thermally conducting manner to the busbar by means of attachment devices (36). In consequence, considerable temperature relief of the busbars can be achieved, and hence a reduction in their cross-section. These cooling bodies (31) advantageously consist of material which conducts electrical current, in particular of aluminium or an aluminium alloy, and are connected to the associated busbar (26) both in a thermally conducting manner and such that they make contact. An arc-shaped C-cross-sectional shape is particularly suitable for the cooling bodies. <IMAGE>

Title: Lever drive
Inventor: SEELIGER KLAUS DIPL ING
IPC: B62M1/24
Filed: 1981-08-11
Abstract: The transmission is double-acting and converts a reciprocating motion input via a lever into a unidirectional rotary motion. Instead of the crank drive customarily used for this purpose, with its disadvantageous sine function and dead centre action, and instead of two freewheels (one-way clutches) driven in opposite directions and acting alternately on a common wheel shaft, levers (7) moved in opposite directions by segment gears (6) are used, the pawls (9) of the said levers interacting with the rim of the wheel (1) in the manner of non-return devices. Depending on their relative motion in relation to the rim of the wheel (1), the pawls (9) alternately have a freewheel or driving action. Further characteristics are: freewheeling and return-stop function of the wheel (1), continuously variable transmission without additional gears, pawls (9) which act as a rim brake in the end position of the levers. <IMAGE>

Title: Process for producing a closed frame
Inventor: BRICKENSTEIN WOLF-JUERGEN
IPC: E06B3/96
Filed: 1981-08-20
Abstract: For closed plastic frames in which mostly hollow profiles are used and are intended, for example, for windows and doors, it is desirable, for reasons of stability, to provide a metal reinforcing frame within the hollow profile. In order to achieve sufficient rigidity, in particular, also in the corner regions of the frame, it is necessary that the reinforcing frame is connected, and thus closed, in the corners in as frictionally locking a manner as possible. The invention permits the reinforcing frame to be connected in the corners, to be precise within the plastic frame which is already closed and surrounds the reinforcing frame. For this purpose, first of all four bars of the reinforcing frame are introduced into the hollow profile of the four frame sides, and the latter are then fitted together on their mitred surfaces to form a closed frame. There are then produced, in the mitred region of the frame, openings through which a connecting means, for the mutual connection of the bars of the inner reinforcing frame, is introduced into the hollow profile.

Title: Composite vehicle wheel
Inventor: REYNOLDS JULIAN LOUIS
IPC: B60B3/12
Filed: 1981-11-13
Abstract: In a composite aluminium wheel for use with an inflatable tyre on vehicles such as passenger vehicles, delivery vans, lorries and the like, an aluminium cast insert is installed permanently and integrally in an aluminium base wheel in order to form a composite structure. The aluminium cast insert is installed in the base wheel in such a way that it cannot carry out any axial movement and is installed specifically by means of drop-forging or shaping by means of roller flanging. The aluminium cast insert can undergo changes for the surface of the composite wheel and contributes to the constructional rigidity of the aluminium base wheel in such a way that a reduction in weight of the rim area of the aluminium base wheel can be achieved.
