Abstract: A mechanism is provided for adjusting the height of the backrest (10) relative to a chair seat. The adjustment mechanism for releasably retaining the backrest (10) in a plurality of selected positions relative to a seat permits the chair to be shipped in a "knocked down" condition and easily assembled by the consumer. The adjustment mechanism includes a channel member (30) that is secured to the backrest, and a support member (40) carried by the chair that is slidably received in the channel member (30) and rigidly locked in selected positions. The support member (40) has vertically aligned rack teeth (72, 74) and the backrest has a movable catch (48) having pawls (52, 54) that are adapted to engage the rack teeth (72, 74). Movement of the catch (48) places the pawls (52, 54) into engagement with the rack teeth (72, 74) to prevent the downward movement of the backrest (10) from a selected vertical position.

Abstract: In the particular embodiments described in the specification, a single pass ink jet printer includes a plurality of ink jet modules (54) arranged in adjacent rows extending across the width of the surface of an object which is moved with respect to the printer. The modules (54) are mounted on and joined to a manifold (84) which is mounted in a support frame (82). Ink is supplied to the manifold through an opening (98) in the frame and the manifold distributes the ink to corresponding openings (66) in the ink jet modules where it is directed to arrays of ink pressure chambers and to an outlet which communicates with a corresponding return passage (102) in the manifold leading back to the ink supply. As a result, ink can be circulated continuously through all of the ink jet modules, thereby maintaining pigment in suspension in a pigmented ink.  An ink supply is removably connected to the printhead through quick-disconnect couplings and, to prevent contamination of the ink in the printhead, filters are provided in the ink supply and at the inlet to the printhead. A further filter (86), designed to trap only those particles which would block the orifices in the orifice plate, is positioned between the ink jet modules (54) and the orifice plate (90). In one embodiment twelve ink jet modules (54) are arranged to provide approximately 275 dot per inch (108 dot per cm.) resolution across a 5.6 inch (14.2 cm.) image width and in another embodiment forty-eight ink jet modules (54) are arranged to provide 600 dot per inch (236 dot per cm.) resolution across a 10.-1/4 inch (26 cm.) image width.

Title: Optical modulator
Inventor: MOODIE DAVID GRAHAM
IPC: G02F1/025
Filed: 1997-02-21
Granted: 2001-08-07
Abstract: A discrete electroabsorption modulator for optical signals has an electrical  blocking region (12a, 12b) which is large as compared with the absorber regi on (13). The height of the blocking region (12a, 12b) is 3 - 20 .mu.m, e.g. 4 -  6 .mu.m and preferably about 5 .mu.m. In addition, the blocking region (12a, 12b) is 2 - 250 times, e.g. 15 - 25 times the height of the absorber region (13). The modulation depth is substantially increased, e.g. to values above 40 dB, by a thick electrical blocking region. It is believed that the thick blocking layer (12a, 12b) works because parasitic signals which escape into the blocking region are spatially removed from the vicinity of the absorber region; thus they are not acquired at the output.

Abstract: In a process for producing a hot reduction gas containing Co and H2 for reducing fine-grained metal ore, particularly iron ore, the reduction gas is formed by gasification of carbon-containing materials, particularly coal, under addition of oxygen in a gasification zone and subsequently cooled to a reduction gas temperature conducive to the reduction process. To produce a reduction gas of greater thermodynamic stability, H2O and/or CO2 are added to eliminate the Boudouard and heterogeneous water gas reaction and teh concomitant warming of the reduction gas.

Abstract: A light weight, strong and flexible, braided electrical fence rope, for fenc es to contain livestock and keep unwanted animals out, combines in its outer braid ed jacket electrically conductive elements with high strength non-conductive elements in a double helix configuration. The outer braided jacket will preferably surround an inner core of nonconductive high strength elements. The high strength non-conductive elements and the physical properties of the braided rope construction provide inherent streng th and flexibility properties to the fence rope. The conductive elements in the outer braided jacket are selected to provide an effective electric shock when contacted by an animal. This electric fence rope combines barrier strength and psychological deterrence to both domestic and wild animals.

Abstract: Call forwarding data, including forward to numbers for a particular mobile station are correlated with a particular service area and stored at a home location register (HLR) associated with that particular mobile station. Whenever the mobile station travels into a mobile switching center (MSC) serving that particular service area, the MSC performs a location update with the HLR. A location update signal further includes data representing the identity of the service area currently serving the mobile station. Upon receiving the location update signal from the serving MSC, the HLR analyzes the received data to determine the identity of the service area currently serving the mobile station and retrieves the call forwarding data associated with that particular service area. The retrieved call forwarding data are then analyzed to determine whether the forward to numbers are located in the current service area for the mobile station and, if so, transmitted back to the serving MSC in order to provide location-based call forwarding to the roaming mobile station.
