Abstract:
An electric lock for remote access control to a container wherein a U-shaped latch is mounted on a door in alignment with a slot in a housing mounted in the container. Upon closure, the latch enters the housing to engage a slotted keeper therein and causes rotation of the keeper. Rotation of the keeper causes a release lever to engage a stepped protrusion on the keeper and secures the keeper and latch. Activation of a solenoid or drive motor coupled to the release lever permits withdrawal of the latch from the housing. The axes of rotation of the keeper and release lever are located to greatly reduce the impact of pre-release forces to the door.
Abstract:
To fold sheets of newsprint (1), a ring gear 7 is driven in rotation by a motor 11 under the control of a controller 12 such that, for most of the time, the ring gear 7 rotates at the same speed as a folding cylinder 2 and arms 8. When it is desired to initiate a folding operation, the ring gear 7 is momentarily stopped or slowed. The relative motion that occurs between the ring gear 7 and planet gears on the arms 8 causes the planet gears 9 to rotate about their axes and respective tucking blades 6 mounted on the planet gears 9 to protrude above the surface of the cylinder 2, where they engage collated sheets on the cylinder surface and push them into the nip of folding rollers (4). Upon completion of the movement of the planet gears 9 and associated tucking blades 6, the ring gear 7 is again caused to move at the same angular speed as the arms 8, such that the tucking blades 6 retain their “silenced” positions below the surface of the cylinder 2.
Abstract:
A method of manufacturing printhead modules which can be combined to form a pagewidth printhead is provided which includes laying out each of the printhead modules on a wafer substrate to be either right-handed or left-handed. At least one of the printhead modules is larger than a reticle step used in laying out that printhead module.
Abstract:
A printer is provided having a printhead of first and second elongate printhead modules and first and second printer controllers configured to receive print data and process the print data to output dot data to the printhead. The printhead modules are parallel to each other, are disposed end to end on either side of a join region, and are of different lengths. The first printer controller is arranged to output dot data to both the first and second printhead modules and the second printer controller is arranged to output dot data only to the second printhead module. One or more of the printhead modules has at least one row of print nozzles and at least two shift registers for shifting in the dot data to at least one row. Each print nozzle obtains the dot data from an element of one of the shift registers.
Abstract:
A typical use of linear or two dimensional spectrometers is to expose the detector area, and then shift the photo-electric charges out of the device in a serial fashion. If the illuminating signal is spatially narrow relative to the size of the array, this will drive down the percent of the detector that is utilized, as only a relatively small number of pixels are used to detect the beam. The present invention proposes a method which capitalizes on this spatial under-utilization, and alters the clocking scheme to maximize the read-out speed of the pixels containing signal information. This type of clocking scheme raises the optical power saturation level of the spectrometer. Such an improvement in optical power handling is beneficial for spectrometer based detection of resonant waveguide grating biochemical binding, since in such systems the performance is frequently limited by spectrometer saturation.

Abstract:
A printhead module having a plurality of rows of nozzles configured to extend, in use, across at least part of a printable pagewidth, the nozzles in each row being grouped into at least first and second fire groups, the printhead module being configured to sequentially fire, for each row, the nozzles of each fire group, such that each nozzle in the sequence from each fire group is fired simultaneously with respective corresponding nozzles in the sequence in the other fire groups, wherein the nozzles are fired row by row such that the nozzles of each row are all fired before the nozzles of each subsequent row.
Abstract:
A type of under-dispenser containment system that is easier to install, inspect and repair primary and secondary piping connections located underneath an above ground dispensing unit. This shallow type containment chamber has angled sidewalls that permit underground pipeline connections to be made directly to specially designed shear valves without the need for a riser pipe assembly.
