Title: Anaesthetic humidifier with movable valve - adjusts throughflow of carrier gas enriched with anaesthetic vapour
Inventor: FALB WOLFGANG
IPC: A61M16/18
Filed: 1990-07-11
Abstract: The load indicator (126, 130) is fitted between the valve body (20) and the valve seat (201), and acts against the opening direction of the valve, and frees the path for the lifting movement of the valve body. To prevent the valve body being blocked on the seat (201), the load indicator has a lift limiter which as the result of thrust-type lift movements over a limit load value can be irreversibly overcome. The load indicator is formed as a clamp (126) fixed to the lift drive (24, 124, 125) for the valve and to the valve seat, and has a deformation point formed as a tongue engaging behind an arresting recess. USE/ADVANTAGE - As an anaesthetic humidifier in which stroke and thrust influences on the controlled feed device are obviated within specific limits.

Patent DE-4129067-A1 (DE)
Inventor: MAHMUD SHABAZ
IPC: G07F7/10
Filed: 1991-09-02
Abstract: In previous electronic devices, functional differences in the equipment features were achieved by producing a multiplicity of different types of device. This multiplicity of types entails a high outlay in terms of production for the manufacturer of the devices. Furthermore, for the customer, the devices often have the disadvantage that he must buy a device having equipment features which he never uses, but still has to pay for at the time of purchase. By the use of a data carrier card which allows an individually desired activation of device functions, it is possible to restrict the multiplicity of types during production. <IMAGE>

Title: Receiver for wire or wireless speech or data signal transmission - has signal reception circuit and speech reception circuit for reception circuit output signal processing
Inventor: MISAWA MASAYUKI
IPC: H04M11/00
Filed: 1991-12-31
Abstract: The reception circuit deals with signals transmitted over wires or by radio.
