Title: A sound synthesizing circuit and method of synthesizing sounds
Inventor: PFEIFFER RANDALL R
IPC: G10H7/00
Filed: 1980-03-03
Granted: 1984-07-19
Abstract: An electronic circuit is disclosed which is capable of producing synthesized sounds under the control of a microprocessor or other type computer. A plurality of switch inputs are provided whereby the sound to be produced can be selected. The processor, under program control, then generates such sounds utilizing one or more basic waveforms stored in a memory. These basic waveforms are modified in specified ways and then outputted through an I/O device to a digital to analog converter for application to an audio system. Eight input control lines to the microprocessor also feed an 8-input NAND gate, such that a momentary change of the normally-high control inputs will cause the NAND gate to activate an interrupt request.

Title: Recharge circuit for a semi-conductor memory
Inventor: HEUBER KLAUS
IPC: G05F3/22
Filed: 1980-06-18
Granted: 1984-07-19
Abstract: Disclosed is a restore circuit for restoring an integrated semiconductor storage array having storage cells consisting of bipolar transistors. The restore circuit includes a reference voltage generator, an impedance converter, and switches to connect the reference voltage generator and the impedance converter to the storage array. The reference voltage generating circuit includes a current source and at least one reference storage cell identical in construction to the storage cells of the array. The reference voltage generating circuit provides a reference voltage to the impedance converter which supplies a second reference voltage to the array at a greatly reduced impedance. The equivalent circuit of the storage cells is that of a capacitor in parallel with a diode. Thus, the impedance converter provides an initial surge of capacitive current which restores the cells, followed by a standby current which is a function of the diode characteristics of the cell equivalent circuit.

Title: Fire detection system with ir and uv ratio detector
Inventor: WENDT ROGER A
IPC: G08B17/12
Filed: 1982-10-19
Granted: 1988-05-11
Abstract: An automatic fire detection system characterized by an extremely low incidence of false alarms utilizes two detection channels, one fed by an infrared (IR) detector and the other by an ultraviolet (UV) detector. Signal processing electronics in each channel produce a normalized output signal proportional to the power of incident IR and UV radiation within specific bandwidths. The system features a ratio detector that repeatedly forms a ratio of the normalized IR and UV inputs and compares the ratio to a known range of values for this ratio that are characteristic of a fire. A discriminator connected to the output of the ratio detector generates a fire alarm signal only if the majority of these ratio comparisons are fire-indicating. The system also includes a feedback loop in the IR processing channel that automatically adjusts the output of the channel to compensate for time-verying background IR radiation such as sunlight.
Patent DE-3363473-D1 (DE)
Title: Comb-like lamellae support for weaving machines, in particular for the weaving rotors of multiple longitudinal traversing shed weaving machines, and method of manufacturing them
Inventor: STEINER ALOIS
IPC: D03D47/00
Filed: 1983-02-18
Granted: 1986-06-19
Abstract: A lamellae comb comprises a carrier or support and lamellae or small plates arranged thereupon which contain lateral projections serving as shed-retaining elements for the warp threads. Each shed-retaining element is formed by a respective projection at the two lamellae enclosing the shed-retaining element. The projections protrude towards each other, conjointly bridge the intermediate space between the lamellae and are mutually offset in the warp direction. Thus, the tube width may be adjusted within wide limits without the lamellae containing the projections having to be exchanged. The lamellae are positioned on the carrier or support by means of racks resiliently supported at the carrier and extending over the weaving or fabric width. The teeth of the racks position the lamellae and have a tooth division or pitch corresponding to the desired tube width of the lamellae. Thus, the lamellae division or pitch does not exhibit any error across the entire weaving width, particularly no summation error, and the lamellae combs can be exactly reproduceably manufactured.
