Title: Power frequency regulation circuit - is for combined grid and local supply system and introduces load shedding in steps based on priority using local turbine pressure
Inventor: SINDELAR RUDOLF DIPL ING
IPC: H02J3/14
Filed: 1979-09-25
Abstract: The power-frequency regulation circuit is for an energy consuming system drawing electrical power from the grid and also from its own power generation unit. The turbine system of the local power unit is regulated by controlling the steam pressure and the nominal power. Load shedding is introduced when there is a likelihood of exceeding the agreed consumption from the grid. The first shedding stage (1) disconnects consuming units listed in a system of priority until the instantaneous consumption of the local turbine set can cover the existing demand. The power drawn from the grid is then controlled until the regulator (18) exceeds a min. value. This is followed by a second shedding stage (2) until a negative regulation error is obtd.

Title: Digital identification of tone signal on telephone line - multiplying samples by sine and cosine of tone and accumulating products
Inventor: RUEDIGER THOMAS ING GRAD
IPC: H04Q1/457
Filed: 1979-09-28
Abstract: Tone signals on incoming lines in a telephone exchange are identified by digital processing of successive samples taken of the line voltage. Each sample is multiplied by sine and cosine of one possible tone frequency and the result accumulated in a pair of stores over four samples. This is done in four channels in parallel, each channel being staggered in time by one sample period. The accumulated result in each channel is squared to make it positive, and compared with a threshold to determine whether that frequency is present. The process is repeated for each of the possible tone frequencies, after having first reset the store contents to zero. The output is in the form of a statement of which tone, if any, is present on each of the lines being monitored.

Title: Starter for solar heating system - uses increase of pressure arising from radiation from sun to operate pressure switch
Inventor: MAILE HANS
IPC: F24J2/40
Filed: 1979-10-19
Abstract: The starter operates on the orinciole of a pressure switch. It is installed in the cellar, together with the usual controls and safety devices, so that there is no time delay and consequent loss of energy when the sun's heat becomes useful. The increase in pressure arising from the sun's rays impinging on the collector(s) is used to operate a pressure switch. The latter is adjustable to match the pressure head of the cold section of the heating installation. When the radiation from the sun ceases to be effective, the reduction in pressure is used to switch the system off. A manometer can be used for pulse generation via a contact and having the same function as the pressure switch.

Title: Formation of magnetic wedges for flat motor stator slots - involves casting stator assembly in synthetic resin, leaving slots for pressing down magnetic wedges
Inventor: WADA MASAMI
IPC: H02K15/04
Filed: 1980-03-26
Abstract: In a flat motor, the wider the stator slot opening, the easier is the mounting of the coil windings. Excessively wide slot openings, however, reduce the effectiveness of the motor. The magnetic wedges are intended for such a flat motor with axial air gaps. The production starts with a stator core, which is embedded in synthetic resin, together with the respective coil windings, in a mould. Thus a stator module is formed with wedge-shaped grooves at the slots for the fitting of the magnetic wedges. In the grooves is moulded a composition consisting of 60 to 95% wt. of iron or iron alloy powder and 40 to 5% wt. of a synthetic resin. Pref. a stator module with radial raised strips is formed for the production of the grooves in each slot. Each such strip is formed with a groove in its middle section. After applying the resin to the mould, this middle section then forms a resin lump.

Title: Solar heating system with heat pump - circulates heated liquid to tank containing heat exchanger coil of heat pump
Inventor: HERBERTZ HEINZ
IPC: F24S10/80
Filed: 1980-07-22
Abstract: The solar heating system uses heat collectors to heat liq. in a tank (11) containing a heat exchanger coil (19) connected by valves (20,21) to an external circuit. It has a trough inside each heat collector, carrying a black perous layer forming a heat absorber. The circulating liquid flows over this layer under a transparent cover. When filled with liq. and the temp. rises above that of the liq. in the tank a pump (9) in the supply line is operated, and the heated liq. flows through a bypass line (14) back into the tank. This heat is transferred to the heat exchanger coil which can be connected to e.g. a heat pump, and a second liq. is pumped through its circuit by a second pump (18). An air release system (15 to 17) is incorporated at the highest point of the bypass line. When the temp. rises, a valve (13), at the lowest point of the heat collector opens when the pump starts.
