Title: Method and apparatus for automatically compensating for degradation of the charge roller voltage in a laser printer
Inventor: MEECE KERMIT ARNOLD
IPC: G03G15/02
Filed: 2000-12-04
Abstract: An electrophotographic printer is provided in which the voltage applied to the charge roller is automatically adjusted to compensate for its changing characteristics over its life span. A high voltage DC power supply includes an output that is connected to the charge roller, and the input side of this high voltage DC power supply is controlled by a microprocessor of the print engine. The print engine controls the output voltage of the high voltage DC power supply by changing the duty cycle of the pulse-width modulated control signal that is supplied to the input of the high voltage DC power supply. Over time, the charge roller characteristics begin to change, and after a predetermined number of prints have been made, the pulse-width modulated control signal has its duty cycle increased by a value that is provided in a look-up table. This increase in the duty cycle is performed several times over the operating life of the charge roller, in order to maintain the effective voltage applied to the photoconductive drum to a nominal value.

Title: Driven plates for friction clutches
Inventor: YOUNG ALASTAIR JOHN
IPC: F16F15/12
Filed: 2001-07-18
Abstract: A clutch driven plate (10) in which the main driven plate assembly (11) is drivingly connected with a hub (12) by means of inter-engaging drive formations (14, 21) which have limited radial and circumferential clearances to allow the main assembly to move radially and circumferentially relative to the hub to a limited extent. The driven plate also has two pairs of opposed surfaces (32, 33; 34, 35) with each pair of opposed surfaces comprising a first surface (32, 34 associated with the hub (12) and a second surface (33, 35)associated with the main driven plate assembly. At least one of the surfaces in each pair is inclined obliquely to the axis of rotation of the driven plate with one of the pairs of opposed surfaces acting to inhibit movement of the main driven plate assembly relative to the hub in a first axial direction of the driven plate and the other of the pairs acting to inhibit movement of the main driven plate assembly relative to the hub in the opposite axial direction of the driven plate. This arrangement allows the main driven plate assembly (11) to tilt relative to the axis of the central hub (12) with the first and second surfaces of each pair sliding relative to one another.

Title: Improvements in or relating to moulding
Inventor: WALLER MARTIN
IPC: D21J7/00
Filed: 2002-08-29
Abstract: A retaining pin (30) for a hollow molded article, such as a male urine bottle (A) moulded from paper pulp and having a neck portion (N) (figure 5-not shown) with an entrance aperture, has a portion (44) which engages with the inner surface of the neck portion (N) of the article in the vicinity of the aperture. When the moulded article is placed on the pin (30) it still contains a lot of water and is thus pliable and by virtue of its weight it is pressed into engagement with portion 44. The portion (44) thus engages with the inner surface of the article near the aperture and forms a smooth inner surface on the article, making it more comfortable to use. A projection 40 of the pin 30 has a surface 42 to engage a portion of the article. The pins 30 are mounted on an endless chain 26 which is moved through a drying oven. The article is dispensed from a mould 20 onto the pin 30.
