Abstract: An improved feed shell positioning mechanism (100) for a rock drilling machine, having a boom (104), a feed shell support (106) pivotably mounted with respect to the boom (104) and supporting a feed shell (102) having a feed shell axis (108), a roll actuator (114) interposed between the boom (104) and the feed shell support (106), and a rock drill (118) having a rock drill axis (120). The rock drill axis (120) and the feed shell axis (108) are parallel and define a reference plane (122).  The improvement resides in a swivel assembly (124) for attaching the feed shell support (106) to the roll actuator (114), allowing the feed shell support (106) to swivel between a forward drilling orientation and a sideways drilling orientation.  The swivel assembly (124) has a roll actuator securing element (126), mounted to the roll actuator (114), and a feed shell support securing element (128), mounted to the feed shell support (106), which are pivotably mounted to each other about a swivel pivot axis (130) which is inclined with respect to the reference plane (122).  With the swivel pivot axis (122) so inclined, the drill axis (120) is moved into closer proximity to a roll actuator axis (116) when pivoted to the sideways drilling orientation, providing a reduced moment arm for forces generated by the rock drill (118).

Granted: 2009-05-19
Abstract: A method for use by a multi-mode, dual band mobile terminal (10) for identifying a presence of a GSM1900 carrier that is channelized into first channels having a bandwidth of 200kHz, and for distinguishing the GSM1900 carrier from at least a TDMA1900 carrier that is channelized into second channels having a bandwidth of 30kHz. The method includes steps of (a) tuning a receiver (16) to a frequency of a candidate GSM1900 channel; (b) determining a value of a received signal strength indicator (RSSI) using a 200kHz receiver passband filter; (c) if the RSSI value is above a predetermined threshold, converting the frequency of the candidate GSM1900 channel into a frequency of a TDMA1900 channel using a predetermined relationship; (d) retuning the receiver to the frequency of the TDMA1900 channel; (e) determining a RSSI value using a 30kHz receiver passband filter for the TDMA1900 channel, and also for at least two adjacent TDMA1900 channels, assuming that two adjacent TDMA1900 channels are not used together in a same cell;  and, if the at least three RSSI values are all found to be approximately equal within some threshold value, (f) making at least an initial assumption of the presence of the GSM1900 carrier. A further step can be executed of verifying that the assumed GSM1900 carrier is not actually a CDMA1900 carrier. The method has an initial step of camping on a channel of a carrier in another frequency band (e.g., a TDMA800 channel), and the steps of tuning and retuning are executed without changing a baseband clock frequency from a frequency associated with the channel that the mobile terminal is camped on.

Title: Universal blow mold assembly
Inventor: TSAU TAR
IPC: B29C49/48
Filed: 2000-07-14
Granted: 2006-10-17
Abstract: A mold assembly has two mold half shells, corresponding mold half carriers, and a novel intermediate interconnecting member comprising a pair of ring shaped locating members. The locating members have an inner locating wall, preferably a stepped shoulder, that fits into a recessed slot in the outer wall of the mold shells. The locating members have an outer wall that fits into a recessed slot in the inner wall of the mold half carriers. The inner and outer locating walls of the locating members are vertically positioned relative to each to determine the vertical registry of the mold shell to the mold carrier. The assembly utilizes a base insert located below the mold half shells having an inner base wall that defines the shape of the base of the container. The assembly has an interchangeable pedestal spacer positioned below the base insert having a thickness chosen relative to the vertical registry defined by the intermediate interconnecting member. By utilizing intermediate interconnecting members of differing relative vertical positioning of the inner and outer locating walls, universals mold shells and mold carriers may be used for containers having differing neck heights whereby the neck height adjustment is accommodated by changing the intermediate interconnecting member. Consequently, quick changes in the assembly can be made by replacing a relatively less expensive interconnecting ring members which are part of the standard spare parts of the mold carrier and pedestal spacer as compared to making new more expensive mold shells.
