Title: Soil compactor reciprocating drive rod - has two cam followers and is operated by rotating twin track cam
IPC: B06B1/10
Filed: 1976-04-10
Abstract: An eccentric drive converts rotary into reciprocating motion. The drive disc (5) includes an external cam (5c) and an eccentric cam track.

Patent DE-2758926-A1 (DE)
Inventor: FATHAUER GEORGE H
IPC: H03J1/00
Filed: 1977-12-30
Abstract: This radio receiver is for receiving messages on frequency bands which are reserved for the public security service. The receiver includes a search device, by which it is tuned repetitively to all frequencies between a lower frequency limit and an upper frequency limit, until a frequency on which a transmitter is operating is found. Provided for this purpose are an oscillator (60, 62, 64, 66, 68), which works with frequency synthesis, for tuning the converter (14, 15) and demodulation (22, 25) devices, and a squelch circuit (30) for detecting a received signal at the frequency set in the receiver. Stepping devices with a computer are connected to the squelch circuit via the said oscillator, so that the receiver is tuned successively to the discrete frequencies, until a signal is received. Data about the frequency limits is entered into the computer using a keypad, and data about the respective channel and the set frequency is displayed in a digital display. In this way, each desired frequency band can be searched for active frequencies, and at the same time received signals can be assigned to known transmitters. <IMAGE>

Title: Telephone call rerouting system - measures signal levels in both directions along line pair to control gain of amplifier
Inventor: WEISS RENE EDWIN
IPC: H04Q3/00
Filed: 1978-02-25
Abstract: The rerouting system measures the level conditions for each rerouted call and produces a control signal for its gain-controlled amplifier. The amplifier's gain is set so that a max. predetermined attenuation is not exceeded nor a max. level. A signal describing the level of the signals in both directions along the line pair is stored. A comparator determines the higher stored level to aid the generation of two reference signals for gain control. The reference signals are produced by an analog computer. The direction of the voice signals is reversed using level detectors, amplifier control switch switches and a change-over switch.
