Title: Multiple receiver heartbeat monitoring appts. - has microphone to convert heartbeats into electrical signals for IR transmitter
Inventor: GRIESE HANS-JOACHIM DR ING
IPC: H04B10/114
Filed: 1980-04-05
Abstract: The appts. is for converting the heartbeats of a patient for audible and/or visible monitoring, first converts the heartbeats into electrical signals. These are modulated by infra red radiation, and are then converted into electrical or acoustic signals. A heartbeat microphone can be used with a voltage supply which is independent of the mains supply and an infra red transmitter. The transmitter generates radiation consisting of short pulses which are frequency modulated. The transmitter can use a mechanical or electronic switching system so that it is operated only during a monitoring period such as when the microphone is brought into contact with the patient. Filters for the heartbeat frequency can be used between the microphone and transmitter. The system eliminates complicated wiring when a number of students may be required to listen to the heartbeats simultaneously, and headphones may be used.

Title: Track-braking system with automatic velocity control - has monitoring check for verifying measured motion resistance of partially filled tanker
Inventor: POEHLMANN ADOLF
IPC: B61J3/02
Filed: 1980-05-24
Abstract: The braking system using incline and descent brakes uses two successive velocity measuring sections to determine the motion resistance of the wagon. A plausibility check on the obtained motion resistance of partially filled tankers is provided by combining the two measured velocity values with the run-through velocity for the incline brake to verify that the motion characteristic provided by the three values exhibits a regular acceleration or retardation. If the measured motion resistance is found to be incorrect it is replaced by a constant value which provides a good approximation to the known motion resistance characteristics for this type of wagon.

Patent DE-3032574-A1 (DE)
Inventor: ROTHER BRUNO
IPC: F21V21/10
Filed: 1980-08-29
Abstract: A reinforcement for a centrifugally cast, synthetic resin pole comprises a woven wire cloth interposed between a mat and an inner layer of a fibrous material. The mat is permeable to the synthetic resin and has a specific gravity lower than the specific gravity of the synthetic resin so that when the pole is fabricated, the mat and the entire reinforcement float on the synthetic resin and are ultimately disposed in the interior of the pole wall. Means for securing a lamp or the like to the pole, such as set screws or collar bands, penetrate the pole only to the woven wire cloth so that further penetration is prevented when the pole is swayed and any wobble or play between the lamp and the pole is avoided.
