Title: Bearing overlay coating of metal substrates
Inventor: COOPER JAMES ARTHUR
IPC: C25D15/02
Filed: 1989-02-06
Abstract: A bearing overlay material is provided comprising a metal (selected from zinc, copper, tin, lead, antimony, indium, silver and alloys thereof) matrix having amorphous carbon contained therein, the overlay being electrolytically deposited onto the bearing from an aqueous electrolyte containing the desired metal ions and carbon. The carbon may be pre-treated either by steeping it in an aqueous acid before electrodeposition or by bubbling an acidic gas through the electrolyte prior to or during deposition. Such an overlay eliminates the need for the nickel interlayer normally found in such bearing systems, which interlayer can lead to problems with scuffing and seizure of the bearing.

Patent GB-907294-A (GB)
IPC: B66B1/30
Abstract: 907,294. Control of D.C. motors. BROOKHIRST IGRANIC Ltd. March 9, 1959 [March 10, 1958], No. 8020/59. Class 38 (3). [Also in Group XXXV] In a Ward Leonard system, comprising motor MA and generator GA, the field winding GF of the generator is supplied from a magnetic amplifier GFPA which is controlled by a preamplifier PRA, and a further magnetic amplifier ACLA is provided for limiting the motor current during acceleration. The speed of the motor is determined initially by the value of a reference voltage applied to the input signal winding IS of the pre-amplifier PRA, a first value of speed being obtained when all three rheostats RH1, RH2, RH3 are in series with the winding IS. The pre-amplifier is turned on by the winding IS which is opposed by a bias winding and a feedback winding FB responsive to the generator voltage. As a result, the pre-amplifier affords an amplified output signal which is applied to the signal winding S of the power amplifier GFPA. A feedback signal representing the armature current of the motor is derived from resistor R1 and applied to the winding FBS of the amplifier ACLA which is opposed by a bias winding. When the armature current becomes excessive, the amplifier ACLA provides an output for a current-limiting winding CL of the power amplifier GFPA. The motor is accelerated to second and third incremental speeds by closing contacts RV1, RV2, to shortcircuit rheostats RH3, RH2 in sequence. To prevent transitory excessive armature currents due to delays in response of the control circuit, the amplifier ACLA is provided with an overshoot limit winding OSL energized from the output terminals of the pre-amplifier. A network F filters the output voltage of the preamplifier which is applied through capacitor C1 to winding OSL. Thus, when the pre-amplifier is first turned on, a current pulse proportional to the initial rate-of-change of the pre-amplifier output is applied to the overshoot limit winding to operate the current-limit amplifier and prevent the armature voltage from overshooting. To test the output of the voltage regulator without actually running the motor, contacts RR1, RR2, KV1 and RV2 are opened, relay UV is de-energized, and a selector switch RTS is positioned to maintain the energization of relay OAC, whereby the power winding of the amplifier GFPA is connected to supply-lines AC1, AC2. When a test selector switch SS is in its position 6S, rheostat RH1 is adjusted so that voltmeter V indicates a predetermined generator voltage corresponding to the highest selected speed. Similarly, when the switch SS is turned to its positions 2S and 1S the rheostats RH2, RH3 are adjusted to provide the appropriate voltmeter readings. Specification 907,295 is referred to.

Title: Corona charger arrangement
Inventor: HIRANO MASAKAZU
IPC: G03G21/00
Filed: 1991-04-10
Abstract: A charging station structure of an electrophotographic image forming apparatus has a photoconductive member (1) provided with a corona charger (20) for uniformly charging the photoconductive member. An opening is defined between one side (12R) of the corona charger and a roof member (31) arranged at a position opposite to the photoconductive member with respect to the opening so that incidence of ambient light onto the photoconductive member through the opening is substantially prevented by the roof member whilst allowing ozone to escape from the corona charger through the opening. The roof member 30 may be formed of an elastic material. The charging station may be used in a laser beam printer (fig 3 not shown) so that even when the so called clamshell or cover is opened the drum 1 is not directly exposed to light and thus prevents deterioration of the photoconductive material on the drum. <IMAGE>
