Patent DE-2920894-A1 (DE)
Inventor: UEDA MAKOTO
IPC: G04G9/00
Filed: 1979-05-23
Abstract: An electronic timepiece of the type having a frequency dividing circuit, and a drive circuit for driving a motor having a rotor, a stator and a driving coil, is provided with a magnetic field detection device comprised of a low impedance closed loop including a low resistance element and the driving coil and a high impedance closed loop including a high resistance element and the driving coil. The driving coil develops an induced voltage when placed in an external alternating magnetic field and also functions to drive the rotor. The strength of the alternating magnetic field is measured by the voltage level developed across the high resistance element and the measuring sensitivity is improved by alternately switching between the low impedance closed loop and the high impedance closed loop. In response to the detection output of the magnetic field detection device, the effective power applied to the driving coil is increased so that the motor performance is not adversely affected by the external alternating magnetic field.

Title: Chemicals dosing feeder - with single acting pump integrated in throwaway chemicals container
Inventor: KERN JOHANN
IPC: C02F1/68
Filed: 1979-08-03
Abstract: A dosing feeder to inject metered amounts of chemicals into a fluid system, specially into the water mains, consists of a drive motor and a metering pump. The latter is a single-acting pump which is an integral part of the chemical storage container. The drive section with a coupling flange is designed as a separate part from the storage container with integrated metering pump. The storage container for the chemicals is thus a sealed vessel which is only pierced when it is coupled to the drive part. This ensures hygienic conditions throughout. No dry running safety features are required and the drive has a long service life.

Title: Earth connection for small motor with external rotor - holds bared end of earth wire in hole in laminar stator packet by deforming hole(NO 30.3.81)
Inventor: DEUTLOFF NORBERT ING GRAD
IPC: H02K11/25
Filed: 1979-12-21
Abstract: The laminar stator packet (3) of the motor has a hole (31) loading inwards from one of its end faces. The bared end (911) of the insulated earth wire (91) fits into this hole. The outside of the stator packet is then deformed (A) so that the hole closes radially and grips the wire end. The point of deformation is near the hole's entrance. The length of wire that can be inserted into the hole can be restricted by a second deformation point (B) along the hole. The wire can then only be inserted as far as this second deformation. Simplicity is combined with toughness and reliability.

Title: Safety mechanism for sliding roof or motor vehicle - has sensor as strip running along frame operating detector when encountering obstacle
Inventor: MINO TAKESHI
IPC: B60J7/057
Filed: 1980-04-24
Abstract: A safety system for the sun roof of a motor vehicle, prevents it from closing when there is an obstacle, such as any part of the body, in the opening. The sliding roof can be operated by hand or by a motorised drive. It has a sensing element in the form of a strip, which runs along one or more sides of the frame of the sliding roof. The sensor and the drive operate in conjunction with detectors, which react when the sensor touches an obstacle. The detector is fitted with a switch linked to the control mechanism of the sliding roof. The sensor responds when subjected to a pressure stress in the plane of movement of the roof.

Title: Pliable bottle filling machine - thrusts mouth edge with slight pressure against seal during initial pressurisation
Inventor: LUEHMANN PETER
IPC: B67C3/24
Filed: 1980-05-22
Abstract: The machine fills bottles, elastic in the lengthwise direction and having mouths narrower than their maximum diameter with drink. It has a filler head with seal for the bottle mouth and a bottle table, these being moved together prior to filling and apart fro bottle-changing. To give back-pressure filling in the filling position, the mouth edge of the unpressurised bottle is thrust with a slight pressure against the seal on the head, sufficient to give a seal during the initial phase of pressure build-up. As pressure continues to increase, the filling position is maintained by stops.
Patent DE-3020194-A1 (DE)
Title: Hot water section for heat storage device - has increased space for circulating air to increase heat absorbed by water
Inventor: FREILING HEINZ
IPC: F28D20/00
Filed: 1980-05-28
Abstract: The heat storage device has a water storage section arranged so that air is allowed to enter and travel over the surface of the water. Heat given up from the air, which is warmer, is absorbed by the water, so as to improve the operation of the storage device. This air, which circulates between the surface of the water and the housing, is also dehumidified. The increase in space for the circulating air is obtained by increasing the height of the flange round the top cover.
Patent DE-3023304-A1 (DE)
Title: Electronic temperature controller for refrigeration compressor - uses temperature dependent resistor and amplifier circuit to gate thyristor motor control
Inventor: BUCHER HEINZ
IPC: G05D23/24
Filed: 1980-06-21
Abstract: The temperature sensing circuit is fed from a constant voltage source (KU) which is part of an I.C., containing an operational amplifier (M-OP) used as a measuring amplifier, and a control circuit (Ast), for a phase-gated electronic switch e.g. Thyristor or Triac. The control circuit (Ast) is fed from an input signal (Sts), derived from the temperature circuit, and is synchronised with the main supply via a synchronising resistor (RSYN). The input signal (Sts) to the control, causes the electronic switch device (T) to conduct and control an electric motor (M) which is in series. The voltage (-U) fed to the circuit of the measuring op-amp (M-OP) is constant and is connected via a voltage divider to one input terminal of the op-amp (M-OP). A temperature-dependent resistor across this op-amp (M-OP) causes the output voltage to vary with change in temperature. From the set and actual values, a control signal is developed, causing the compressor motor (M) to run until the required temperature is obtained.

Title: Cable operated grab for dredger - has oil holes through cable pulleys supplying roller bearing lubricating chambers between pulleys
Inventor: KROEGER WERNER
IPC: B66C3/12
Filed: 1980-06-24
Abstract: The heavy duty grab, e.g. for a floating dredger, has its jaws swung open by cables passing around a row of e.g. four pulleys. It incorporates a lubrication system using the spindle (19) on which the pulleys are mounted. The pulleys are spaced in pairs (16,21; 22,23) with a spacer collar (25) between the two pairs. At the outer end of each pair is a flanged collar (26). These three collars and the hubs (26) of the pulleys are shaped to form annular chambers (45), concentric with the roller bearings (35,36). These chambers receive lubricating oil from radial oil holes (51) through the spindle, supplied by axial oil holes (53) extending inwards from each end of the spindle. The roller bearings inside the pulley hubs are separated from each other by oil chambers (48 to 50).

Title: Fixed bed gasification reactor - with oxygen-contg. gasifying agent injected through molten slag bath
Inventor: VIERRATH HELMUT DIPL ING DR
IPC: C10J3/08
Filed: 1980-09-03
Abstract: Solid fuel is gasified in a reactor at a pressure of 1-100 bar, using oxygen, steam and/or carbon dioxide as gasifying agents. The fuel moves slowly downward in a fixed bed and the lio. slag is extracted below the bed. The oxygenous gasifying agents are introduced at several points through the molten slag into the fixed bed. This ensures a uniform distribution of the gasifying agents (specially oxygen) over the entire cross-section of the reactor. The slag is always kept at a high enough temp.
