Title: Ear protecting muffs - have microphone sound reproducer and amplifier to regulate sound reaching ear
Inventor: GRIESE HANS-JOACHIM DR
IPC: A61F11/14
Filed: 1979-06-22
Abstract: Ear muffs which protect the ears from excessive noise have the disadvantage that they produce a sensation of isolation. In some active systems a compensating sound is produced which, however, suffers from resonance effects. This device introduces an almost continuous note in the earmuffs which is independent from the external noise. A microphone (3) in the space between the muffs and the ear picks up some external noise and the compensating note emitted by a small sound reproducer (2) included in the same space. The total sound level is regulated by a small battery driven amplifier (4) in the muffs which may be preset to any tolerable sound level. The system thus is independent of phase shifts and resonance effects.

Title: Automatic exposure control for camera - achieves constant response by operational or differential amplifier
Inventor: JEHMLICH HANS DR
IPC: G03B17/18
Filed: 1979-10-24
Abstract: An automatic exposure control for a camera has a differential or operational amplifier with one input from the film speed sensor and the other from the photocell. The output is fed back to a transistorised control with switching circuits for the exposure settings. The system uses switching circuits with constant threshold voltages so that a constant response is obtained over a wide range of conditions. The exposure settings are also independent of the supply voltage for the switching circuits. An adjustable control (2) and a series connection of a photo-resistor (3) and transistor (4) are switched in parallel to the power source (1). The tap of the control (2) is connected to the inverted input of a differential amplifier (5). The latter's output is fed back to the transistor's (4) base.

Title: Brush-type current supply for electric machines - uses one or several insulated detector contacts, opened or short-circuited according to brush wear
Inventor: SCKERL WALTER
IPC: H01R39/58
Filed: 1980-04-10
Abstract: The current supply uses one or several brushes, as well as components pressing the brush(es) against a commutator, a slipring, or any other counter-contact. The brush current supply system has one or more insulated electric detector contacts, opened or short circuited by the metal portions of the brush compression components in dependence on the brush wear, using a configuration of a detector circuit. Preferably two mutually insulated detector contacts are used for each current supply. Alternately, a single detector contact, insulated against the current supply, may be used. The short circuiting metal portions for the detector contacts may be also insulated against other parts of the current supply system. These insulated portions may have a different resistance. In this manner the uneven wear of carbon brushes of synthetic carbon can be detected and remedied.

Title: Async. generator driven by combustion engine - has electromagnet in load circuit controlling speed of engine
Inventor: GERTHS GERALD ING GRAD
IPC: H02P9/04
Filed: 1980-06-11
Abstract: The generator has at least one electromagnet in its load circuit. The electromagnet is coupled to a speed setting device belonging to the set that drives the generator. The electromagnet adjusts the speed setting device and therefore the speed of the drive set. The drive set may be a combustion engine and the electromagnet may act on the accelerator pedal of the engine. The electromagnet is actuated at roughly half the rated load current and increases the speed of the engine. The advantage lies in improving the voltage characteristics of the capacitively-excited async. generator by making its voltage independent of load current and speed.

Filed: 1980-06-30
Abstract: A telephone answering machine using an alterable read only memory, e.g. EPROM, EAROM or EEROM for storing the recorded answer message in delta modulated PCM form. The machine also contains bubble storage capacity for recording messages from incoming callers. The scanning frequency for the magnetic bubble memory storage capacity is less than 40 kHz but at most 8 times and at least twice the top frequency to be recorded. More usually it is 2x or 3x the top frequency. The design employs integrated circuits to achieve small size and high storage capacity. Additionally the memory is non-volatile and therefore unaffected by power failures. The EPROMs can be suffused with UV light in the normal way for programme changing.

Abstract: Briquettes are pressed using fine oxide dust particles, e.g. dust obtd. from smelting works, and fine ore, together with a high proportion of turnings or swarf obtd. during machining operations. The briquettes are then used as a raw material in melting furnaces. The mixt. used for the briquettes pref. contains by wt. 20-80% of turnings or swarf, and consists esp. of equal parts of oxide dust and turnings or swarf. Swarf obtd. from machine shops, and ferrous dust from smelting- or blast furnace-plant can be reclaimed and used in cupola furnaces. Inexpensive waste materials can be used as part of a charge being melted in a cupola furnace; and when the briquettes contain a high percentage of swarf, they can also be re-used in induction melting furnaces.
