Patent DE-2350511-A1 (DE)
Title: Portable inflatable hood hair dryer with low voltage D.C. motor - has light-weight temperature control with apertures partly closed by revolving cover
Inventor: HUEBNER OTTO
IPC: A45D20/26
Filed: 1973-10-08
Abstract: The motor socket or holder is enclosed in a hood or dome which in the area of the air inlet opening leading to the inflatable dryer hood has air inlet apertures which can be at least partially closed for controlling the drying effect. The air inlet apertures are formed from recesses set spaced round the perimeter of the dome housing and can be closed by segments or strips which adjoin the inside of the lower edge of the dome housing and can be rotated relative to the apertures. A stop ensures the apertures are never completely closed and although the air temperature is increased by reducing the total air flow through the apparatus the flow rate is increased owing to the smaller apertures so that the heat given off by the air flowing through is reduced due to the smaller temperature difference between air and the wire coil of the motor so that heat control is possible.

Title: Control of accelerator-pump of carburettors - by delaying-devices placed between gas-lever, accelerator-pump and throttle-valve
Inventor: AUGUST PAUL DIPL ING DR
IPC: F02M7/08
Filed: 1974-10-15
Abstract: A device for the control of the accelerator-pump and of the throttle-valve in internal combustion engines by means of the gas-lever consists of delaying-devices, which are placed between gas-lever, accelerator-pump and throttle-valve, so that, on acceleration, the accelerator-pump is operated before the throttle-valve. The delaying-devices are adjustable. The accelerator-pump is thus operated so that, at the instant of acceleration or idling, respectively, the air for combustion is immediately supplied with motor fuel. At the same time, adjustment of the motor fuel/air mixture is maintained at lambda 1 and over, so as to ensure low CO-values and CH-values. A baffle plate controls the delay device electronically.
