Title: Charge-transporting vinyl metallocene copolymer
Inventor: BAUMGARTNER ARMIN
IPC: G03G5/07
Filed: 1982-12-09
Abstract: A charge-transporting organic substance for use in electrophotography, is a copolymer of a vinyl metallocene and a styrene compound. Preferably the copolymer comprises vinyl ferrocene, styrene and, optionally, hydroxyethyl acrylate.

Title: Heated airflow delivery apparatus
Inventor: AHMED KHAL IL
IPC: H02P7/285
Filed: 1983-10-24
Abstract: Apparatus, such as a hair dryer or a fan heater, for delivering a heated airflow includes an electric motor (6, Fig. 1) coupled to a fan and connected by way of two parallel connected heating elements (2) to load terminals 4 which are connectable to power supply terminals 10 via a double pole switch 12 and a thyristor 25. A pulse generating circuit has a variable resistor 22 arranged to vary the frequency of the pulses which are fed to trigger the thyristor and hence connect the motor and the heating elements to the power supply terminals 10. The power supplied to both the motor and the heating element is thus dependent upon the frequency of the pulses and can be varied by adjustment of the resistor 22. The pulse generator comprises a multivibrator 19 triggered at zero crossings of the A.C. supply by a gate 1850 that thyristor 25 turns on and off at zero crossings. In an alternative circuit (Fig. 3), switching of the thryristor (125) is not controlled to occur at zero crossings. The power output is indicated by the flashing rate of an LED 24. The fan motor may have a flywheel. <IMAGE>

Title: Apparatus and method for fabric cleaning with foam
Inventor: NYSTED LEONARD N
IPC: A47L11/34

Abstract: An apparatus and method, particularly adapted to clean fabrics, is disclosed. The apparatus (10) includes a generally hollow head (14) having two foam mixing chambers (15, 16) in close proximity to a vacuum chamber (17). Foam is generated adjacent the fabric to be cleaned by admixing pressurized air and a liquid foam-producing agent from pipes 24, 25 in the two mixing chambers (15, 16). The air pressure directs the foam from the second mixing chamber (16) towards the fabric. Two screens (50, 52) are used to control the consistency and application of the foam. Suction is simultaneously provided in the vacuum chamber (17), so that the foam is rapidly and continuously recovered. A brush means (20) is positioned between the second mixing chamber (16) and the vacuum chamber (17) to further agitate the foam and fabric to be cleaned, and to help create a partial pressure when the moving foam is applied to the surface of a fabric. <IMAGE>
