Title: Non-releasable connection between hub and shaft - has hub deformed into recess in shaft by press tool
IPC: F16D1/072
Filed: 1978-05-05
Abstract: The non-releasable connection between a shaft and a hub (18) has the shaft provided with a recess in its periphery and the hub deformed to fill the recess. The recess may be part of a cylindrical surface centred on an axis perpendicular to the shaft axis. The deformation of the hub is carried out by a press tool which is urged into a side face of the hub in a direction perpendicular to the shaft axis. The displacement (20) of material by the tool results in adjacent material (21) flowing into the recess of the shaft to establish the connection.

Patent FR-2449923-A1 (FR)
IPC: G05D23/19
Filed: 1979-12-31
Abstract: All the setting elements for individual wishes of the temperature characteristic of inhabited rooms are contained in the room appliance (1) together with a temperature sensor (30). Said appliance is connected to the feed temperature controller (6) of the heating installation via a few lines (4, 5; 8). The room appliance (1) is fed, like the controller (6), with a voltage (U) from the same feed lines (4, 5). The additional line (8) transmits desired value commands to the controller (6). The voltage (U1) of said line (8) with respect to the feed line (5) can be varied as command variable from the room appliance (1). In the event that U1 = U DIVIDED 2, the controller (6) exercises control in accordance with its external sensor in a purely weather-driven fashion. Triggers (9, 10) respond starting from specific differences between the actual value and desired value of the room temperature and effects complete switching on or off of the heating power. Via at least one amplifier (18, 19), a programmer and desired-value transmitter (14) influence the voltage (U1) and a temperature-measuring device (24) in order to form the difference between the desired and actual values. The triggers (9, 10) are provided by two transistors together with one further amplifier (28, 29) each of the temperature-measuring device (24).
