Title: Non-concentric oil separator
Inventor: BOEHDE MICHAEL C
IPC: B01D45/12
Filed: 1995-06-13
Granted: 1998-11-03
Abstract: An oil separator (10) for a refrigeration system (100) employing a screw compressor (108) includes a generally cylindrical, vertically upstanding housing(12) the bottom of which defines an oil sump (16) and the top of which is penetrated by discharge conduit (26) connecting the oil separator (10) to the refrigeration system condenser (102). The centerline (28) of the discharge conduit is parallel to but offset from the centerline (30) of the separator housing so that the discharge conduit (26) is non-concentric with the housing (12). As a result, an enlarged tangential inlet (20) to the interior of the separator is made possible which is unimpeded by the discharge conduit (26). The cross-sectional flow area through which the mixture discharge from the compressor (108) passes prior to entering the separator (10) can therefore likewise be increased. As a result, pressure drop in the refrigerant gas as a result of the oil separationprocess is reduced and overall system efficiency is enhanced while the diameter of the separator housing is minimized.

IPC: B65D83/06
Filed: 1997-12-19
Granted: 2002-12-10
Abstract: Hopper plug (143) vents out air pressure build-up which cause toner leaks.  One side of the plug has a series of entrance openings (491) which communicate with the inside of the hopper (61).  Air, potentially containing some toner particles, passes through those openings and enters a first chamber (507).  The first chamber has exit holes (499) which do not face the entrance openings.  Air passing through the exit holes of the first chamber enters a second chamber (509).          The second chamber has exit holes (495) which are at the opposite end and do not face the entrance openings.  Third chamber (511) of this labyrinth faces a mat toner filter (501) which leads to exit holes (503).

Abstract: A dispenser (10) for dispensing relatively low viscosity material includes a plunger (22) that is movable in a chamber (16) containing the material and a lever (30) that is movable to advance the plunger (32) in the chamber (16). A full stroke of the lever (30) dispenses no more than a single drop of material from the chamber (16). A cap (38) is detachably connected to an outlet (18) of the chamber (l6) and includes an ann (44) in contact with the lever when the cap is connected to the outlet for releasably retaining the lever (30) in a fixed position to prevent unintentional discharge of material from the chamber (16). A  stop (36) comprising one or more sets of teeth is connected to the lever (30) for hindering advancement of the plunger (22) after the lever (30) is released. In certain embodiments, the dispenser (10) includes two side-by-side chambers (16, 16), and a mixing tray (60) has a well (66) with side recesses (68) for receiving protruding outlets (18, 18) of the chambers (16, 16).

Title: Liquid discharge method and liquid jet apparatus
Inventor: KASHINO TOSHIO
IPC: B41M5/00
Filed: 1998-07-27
Granted: 2003-09-30
Abstract: A liquid discharge method is designed for a liquid jet head provided with first discharge openings, a first liquid flow path conductively connected with each of the first discharge openings, first energy generating devices for generating energy for the discharge of droplets from the first discharge openings, second discharge openings, a second liquid flow path conductively connected with each of the second discharge openings, and second energy generating devices for generating energy for the discharge of droplets from the second discharge openings.  Then, preceding the discharge of the first droplet from the discharge opening at a first discharge speed V1, the second droplet is discharged from the second discharge opening at a second discharge speed v2 smaller than the first discharge speed, and before each of the liquid droplets being impacted on an object, the first liquid droplet and the second liquid droplet are allowed to collide with each other to be combined.  In this way, it becomes possible to allow two droplets to be in contact or to collide with each other reliably to be mixed between the liquid jet head and the object within a range that does not render any hinderance practically even if discharge speeds may fluctuate, hence obtaining precise images in higher quality.

Abstract: An improved process and apparatus for the formation of a spun-bonded fibrous web suitable for service in nonwoven end uses. A melt-processable thermoplastic polymeric material is melt-extruded to form a multifilamentary spinline (2), is quenched, and is wrapped about at least two spaced driven draw rolls (14, 16) that are surrounded by a shroud (12) prior to collection to form a web (40), and is bonded to form a spun-bonded nonwoven product. The draw rolls (14, 16) exert a pulling force on the multifilamentary spinline (2) so as to accomplish drawing of the molten multifilamentary spinline (2) prior to complete solidification. The shroud (12) makes possible the self-stringing of the spinline (2) around the draw rolls (14, 16). A pneumatic jet (32) located at the exit end (24) of the shroud (12) assists in the contact of the multifilamentary spinline (2) with the draw rolls (14, 16) in order to facilitate the imposition of a uniform pulling force and expels the multifilamentary spinline (2) in the direction of its length toward a support (38) where it is collected. The formation of a highly uniform spun-bonded nonwoven product is made possible on an expeditious basis.

Title: Allocation of control channel in packet radio network
Inventor: MUSTAJARVI JARI
IPC: H04W8/26
Filed: 1998-03-27
Granted: 2007-11-27
Abstract: A method for the allocation of a control channel (PACCH) to mobile stations (MS) in a packet radio system, particularly in a GPRS system. The mobile station (MS) sends a resource allocation request (3-1), to which a network (BSS) responds (3-2) by allocating to the mobile station (MS) a TFI identifier and a USF identifier.  The network then sends (3-5) data packets in blocks, at least some of which comprise a polling field (S/P), a polling state ('P') which indicates that the mobile station is to acknowledge received data packets on the control channel (PACCH). To ensure that a mobile station receiving in downlink would not prevent the network from allocating one uplink mobile station to said channel, the allocation of the control channel (PACCH) is, in accordance with the invention, independent of a possible USF identifier. The mobile station acknowledges (3-6) the received data packets after a predetermined time (T) from the downlink block in which said polling field is in the polling state ('P'). The predetermined time (T) can be fixed or it can be indicated in an additional extension field (EF2).
