Patent DE-2636848-A1 (DE)
Title: Telephone with loudspeaker and amplifier - includes wall mounting bracket supporting both receiver and handset in cradle
Inventor: BOPP FRIEDEL
IPC: H04M1/11
Filed: 1976-08-16
Abstract: The desk-top telephone unit with loudspeaker, sound channel and amplifier can also be mounted on a wall by using a profiled bracket (9) beneath the unit's bottom edge (when on wall) and a retaining pin (16) driven into the wall at the rear towards the top of the unit. The bracket has a flat portion to support the main body of the unit and two projecting hooks (12, 13) to hold the handset (2) in place on the unit (handset now vertical). The hooks are shaped so that when the handset is replaced it automatically operates the cradle switch and is retained in its now vertical seat.
Patent DE-2650249-A1 (DE)
Title: Stabiliser for chimney draught - has positioning motor driven rotary damper with deflecting vane controlled by thermostats
Inventor: OEZ YUEKSEL
IPC: F23L13/02
Filed: 1976-11-02
Abstract: The stabilizer mechanism built into the chimney maintains a constant optimum draught and compensates effects of intermittent burner operation due to varying heat demands or effects of changing outside climatic conditions. The mechanism consists of a damper (3) built into the flue pipe (1) and mounted on a shaft (6) seated in bearings (4). One of the shaft ends is connected via a coupling (8) and pin (7) to the gearbox (9) driven by an electric motor (10). When the heat demand is satisfied, thermostats in the hot water space of the boiler stop the burner and in order not to lose heat due to ensuring natural draught, a control circuit operates the motor which turns the damper into the shut position. On the other hand, if climatic conditions vary so that an increase of draught would follow with a subsequent combustion air surplus ratio increase, the flue flow through the pipe (1) hits the vane (2) fitted perpendicularly to the damper plane and the damper tips from its fully open position into a throttled position, thereby restoring the optimum air surplus ratio.

Title: Automatic vehicle headlamp adjustment system - has lamp held in correct position by weighted pendulum and then locked in position
Inventor: FRIGGER HORST
IPC: B60Q1/10
Filed: 1977-01-13
Abstract: The headlamp is pivotable on an horizontal axis (5) and there is a weighted pendulum fixed to the lamp pivot which keeps the headlamp correctly adjusted. The headlamp is locked in position in relation to its pivot axis by an adjuster screw (11). Set screws located in front of and behind the pendulum limit the swinging movement. An armature (9) is fixed in a suitable position on the pendulum. It works with an electromagnet (10) to keep the pendulum in a vertical position during travel. The electromagnet is excited by the high tension ignition circuit.

Patent DE-2723144-A1 (DE)
Title: Combined energy system for domestic use - has provision for storing peak output and reducing peak demand
IPC: F02G5/04
Filed: 1977-05-23
Abstract: A diesel engine or gas turbine (1) drives an electrical generator (2). The exhaust gases (3) of the engine are used to heat the building or raise domestic hot water. The output of the generator is supplied through controllers (10, 12, 16, 18, 20) to electric heaters (11), a cooker (13), electric power points (17), a hot water cylinder (21) or other appliances (18). The controllers are regulated so that they progressively reduce the load if it increases beyond the generator output. A further controller (12) can connect a public supply system (15) either to make up a deficiency of power or to receive any excess generated. The excess can also be used to heat an energy store (21) in the form of hot water. A cooling circuit can dissipate heat to avoid dangerous temperatures.

Title: Tapered horizontal slots formed by rotating rollers - provide transfer and orientating track for bobbins
Inventor: KUEPPER WILHELM
IPC: B65H67/06
Filed: 1977-05-27
Abstract: A sorting and transfer installation for bobbins has inclined walls in order to form a collector. At the bottom of the collector, a number of tapered horizontal slots are provided. The slots are formed by rotating rollers, which are driven by a common worm gear shaft. A triangular deflector, above and between the two tapered slots, helps the bobbins to fall into the horizontal transfer slots. Since the bobbins are tapered, their larger dia. ensures that they move in a vertical position along the tapered slots until the slot width is larger than the max. dia. of the bobbin, at which they fall into the transfer chute below.

Title: Hand operated wire twisting tool - has torsion member accommodating ends to be joined under tension
IPC: B65B13/28
Filed: 1977-11-16
Abstract: The hand-operated tool twists two wire ends together, using a rotary round torsion member gripping the ends. During the twisting operation this member is subjected to a pushing or pulling action, and secures the ends under tension. The insertion end can be funnel-shaped, the funnel portion leading to an oblong opening in the torsion member accommodating the wire ends. This oblong opening can be a slot extending radially from the centre, and whose width is twice the wire thickness. The wire ends are secured in it by a pivoting clamping jaw. The member can rotate with a screwed bar forming part of a ratchet mechanism, there being an actuating sleeve sliding along the bar. A tubular housing encloses member and sleeve, and slides along the sleeve, holding the clamping jaw free in opposition to a spring. The slot in the member extends to the outer periphery. The jaw engages when the housing is slid clear of it.

Title: A=D conversion using analog to frequency conversion - and interchanging inputs to comparator synchronously to counting period to eliminate offset error
Inventor: GLAUERT WOLFRAM DR
IPC: H03M1/00
Filed: 1978-01-25
Abstract: The A - D conversion method involves analog to frequency conversion followed by pulse counting. The analogue voltage is applied to a comparator, and a clock pulse controlled pulse shaper stage is connected to its output. Its output signal is fed back to the comparator input either in integrated form, or direct if the comparator acts as an integrator. During measurement the compartor's inputs are transposed once during a switching-over signal period. The comparator's output is connected to an invertor during half the period, so that its offset voltage polarity is reversed. This switching is done synchronously with a counter output.
