Title: Gear pump or motor, modified for better bedding-in - has notches in tooth leading edges to reduce parings quantity
Inventor: BOSCH PAUL
IPC: F01C1/08
Filed: 1976-09-28
Abstract: The gearwheel type pump, motor, modified for better bedding-in can be internally or externally meshing. The modification consists of notching the tooth leading edges at intervals and functions by reducing the amount and particle size of material removed from the casing. Notches are (roughly) evenly spaced; pref. staggered on successive teeth. Ratio of notched length to tooth edge length remaining is not critical but they should pref. be equal. Notches are rectangular in plan; roughly triangular or rectangular in profile. They extend only a little way across the tooth tip and down the flank, can thus be used with pointed or short teeth. Best method of forming the notches is determined by the tooth material.

Title: IC engine carburettor with self-adjusting flow - has air intake volume dependent piston to regulate fuel flow
Inventor: MINECK FRED
IPC: F02M19/02
Filed: 1976-11-11
Abstract: The carburettor consists of a cylindrical housing (11) fixed between a flange mounting (12) and an air filter base (13). The fuel enters a cup-shaped chamber (21) held by two straight brackets (14, 15) fitted crossways and above the air filter base. The fuel outlet (23) extends through the two brackets to be regulated by a taper needle (31). The needle is held by a bullet-shaped cylinder supported by a larger two-part cylinder (41, 42). A spring (29) attached to the throttle flap (74) presses against the two-part cylinder, so that by a closed throttle condition, the needle valve is held at its highest position to prevent a fuel flow. The needle valve forms a venturi with the fuel outlet (23) allowing the fuel to mix with air. The mixture then passes through the two-part cylinder to mix with a second air flow from the filter housing. The second air flow passes a venturi formed by the carburettor housing inner wall (72) and the two-part cylinder. The cylinder is depressed to regulate the fule flow for cold start purposes by means of a crank (68) mechanically coupled to the throttle valve rod.

Title: Gas laser output stabilisation by discharge current modulation - uses control element in laser circuit for synchronisation of plasma waves at given frequency
Inventor: PENNING UWE DIPL ING
IPC: H01S3/134
Filed: 1978-01-02
Abstract: The output power of gas lasers is accompanied by a noise, depending on the output power and construction parameters of the laser. The noise frequency is approximately 500 kHz, and it is caused by the plasma waves in the discharge. If the discharge current is modulated by a control element incorporated in the circuit, a synchronisation of the plasma waves takes place at a certain frequency. Thus the noise spectrum of the laser output contains practically only this frequency, which results in a considerable reduction of the noise and a higher stability of the laser output power.
