Abstract: A trigger  arrangement  for  a  fire  protection  system of  the kind  in  which  a  fire  extinguisher  is  triggered  by  the  relaxa-tion  of tension  in  a  wire  that  is  trained through  a  region  to be  protected  and  kept  under  tension.   A  fusible  link  forces  a portion of the wire  to  lie  along a  curved path.   When the  fuse part  of  the  link  melts,  the  link  releases  the wire,  allowing  it to  straighten  out,  thus  increasing  its  overall  length,  relaxing the  tension  and  triggering  the  extinguisher. The  link  of  the invention  is  simply  an  integral,  laminated  body  in  which  the laminations,   held  together   by  an  adhesive,  fusible  material, are formed with wire  guide means  for  restraining the wire  in  a looped  configuration  so  long  as  the  laminations  are  held  to-gether.

Abstract: In a digital data demodulating apparatus, a sampling circuit samples a received signal at a speed N x K(N > 1, K > l; integers) times a symbol rate to output received signal sequences.  N received signal sequence selection circuits estimate channel impulse responses from the respective received signal sequences to obtain channel state data, and output a control pulse and the estimated channel impulse response values.  A received signal sequence selection controller outputs a switch control signal on the basis of the channel state data.  N selectors select demodulation received signal sequence candidates from the received signal sequences on the basis of the control pulse.  A first switch selects/outputs a received signal sequence to be demodulated on the basis of the switch control signal. A second switch selects/outputs an estimated channel impulse response value estimated from the received signal sequence to be demodulated on the basis of the switch control pulse.  A demodulation circuit performs demodulation upon reception of the outputs from the first and second switches.

Abstract: A primary gradient coil (4') and a screen coil (5') with the primary coil (4') are constructed to create a substantially null field adjacent to the gradient coil (4'). This coil (3) related to active electromagnetic field screen coils of restricted length and a method of optimizing the magnetic fields created by such coils over one proximate volume while maintaining a null field over a second proximate volume. A method is disclosed for generating the coils (4', 5') by considering the screen coil to be of infinite length, deriving a Fourier transform of the axial and other components of the field in which the transform is the sum of the per-missible harmonic modes on the coil surface in which a coefficient C n is derived representing the nth harmonic. A perfect screen coil is created and the number of terms C n selected using least squares optimization until there is no longer a signifi-cant change in the resulting field. Examples are given in for creating unscreened, screened, linear, axial and transverse gra-dient coils.

Abstract: In this lift installation for zonal operation with immediate allocation of zone calls, the passenger traffic between at least one main stopping place (HH) and zones in a high building is managed by a lift installation (ABC) consisting for example of three lifts (A; B; C). The passenger traffic filling the building and arriving at the main stopping place (HH) is symbolised by arrows (P0; P1 to Pn) pointing to the lift group (ABC). The passenger traffic leaving the building and arriving at the main stopping place (HH) is symbolised by arrows (Pa) pointing away from the lift group (ABC). Each lift user filling the building passes one gateway (G0; G1 to Gn), which is associated with a zone and in which a sensor (S0; S1 to Sn) registers the lift user. Through the choice of the appropriate gateway (G0; G1 to Gn), the lift user informs the lift control of his desired zone without manual actuation of a call-registering equipment. The signals of the sensors (S0; S1 to Sn) are passed on to the control equipments of the lifts (A; B; C), which in turn inform the lift user before leaving the gateway (G0; G1 to Gn) of the respectively allocated lift by means of an indicating equipment (D0; D1 to Dn).

Title: Intelligent call processing based upon complete identification of calling station
Inventor: GUTIERREZ FRANKLIN
IPC: H04Q3/00
Filed: 1994-08-04
Granted: 1998-08-25
Abstract: An intelligent call processing system is arranged so that each originating switch is provided with a local database called a "global title translation (GTT)" database, which receives a query fully identifying the calling station, typically in terms of its 10 digit number (i.e., three digit [NPA] area code, three digit [NXX] exchange, and four digit line identification). The GTT database responds to the query by identifying the particular NCP in the telecommunications network that contains the appropriate record for completing the call. If the GTT database does not contain an entry, or an error condition exists, a further query is launched to a centralized database, called a "universal global translation (UGT)" database. The UGT database then retrieves information identifying the particular NCP in the telecommunications network that contains the appropriate record for completing the call, and provides this information to the originating switch. The same information may also be provided to and stored in the GTT database, so that the GTT database is "self provisioning".

Title: Flow conditioner for more accurate measurement of fluid flow
Inventor: BEATY RONALD E
IPC: G01F1/42
Filed: 1994-12-21
Granted: 1999-03-16
Abstract: A flow conditioner for use in pipelines to isolate a measuring device from the effects of piping induced disturbances thereby allowing more accurate metering of fluids flowing in pipelines.  The device comprises three sections:  an anti-swirl device; a settling chamber; and a profile device.  The three sections are installed in a pipeline at a predetermined distance upstream from a metering device and at a minimum predetermined distance downstream from a pipeline disturbance.  In the pipeline, the anti-swirl device is the furthest upstream, followed by a settling chamber of a specified length, which in turn is followed by the profile device.  The anti-swirl device substantially eliminates swirl, the settling chamber minimizes interaction between the anti-swirl device and profile device.  The profile plate produces pseudo-fully developed turbulent structure and velocity profile so there is a minimum deviation of the empirical discharge coefficient or meter calibration factor for both short and long piping lengths.  In certain circumstances, the unique profile plates provided may be used without anti-swirl devices.
