Title: DC motor speed control circuit - uses series chopping transistor with energy recovery to reduce hysteresis
IPC: B41J7/34
Filed: 1975-02-07
Abstract: The speed control circuit for a DC motor includes an oscillator (17) which gates a transistor (16) in series with the motor and the power supply. An additional inductance and diode network is provided in that series path. A capacitor is connected across the motor. When the transistor is switched on, current flows in the motor and the capacitor charges. When it switches off, stored energy in the inductance passes to the motor and at a certain voltage level the capacitor discharges into the motor. This increases the average DC level into the motor and reduces hysteresis and copper losses. The oscillator can be tripped by detecting the voltage across the motor to maximise the effect.

Title: Pipe tapping joint forming unrestricted internal passage - has compression ring located in union nut by projecting lip
IPC: F16L37/092
Filed: 1975-07-31
Abstract: The pipe tapping joint comprises a union nut (2), which is counterbored to house an 0-ring seal (11) and compression ring (13). The nut screws into a housing (1) and this forces the compression ring into the counterbore. Since the diameter of the latter reduces with depth and the compression ring has a matching shape, the ring is compressed radially on to the pipe (4) at the same time as it compresses the ring seal (11) into the nut. A small anular lip (13b) projects from the internal edge of the compression ring and locates the latter firmly by deforming the outer surface of the pipe. Compression of the ring is assisted by forming longitudinal slots (70, 74) in its surface.
