Granted: 1991-02-12
Abstract: TEST ADAPTER FOR INTEGRATED CIRCUIT CARRIER     ABSTRACT OF THE DISCLOSURE A  test  adapter is provided for connection to a PLCC (Plastic   Leaded   Chip   Carrier),  hereinafter referred   to   as  a  carrier, which  assures  accurate alignment  with  the carrier, which can be locked to the carrier  during  a test, which has a width only slightly greater  than  that  of the carrier to enable testing of closely  mounted  carriers,  and  which  can  be  simply constructed.    The  adapter  includes  can inner housing that  bears  against  the  top  of  the carrier and four contact  frames  pivotally  mounted  on  the housing and carrying  contacts  that  engage  leads  of the carrier. Each  contact frame has separators between the contacts, the  separators passing between the leads of the carrier to  directly  engage  the  sides of the carrier housing. the   lower  surface  portions  of  the  separators  are slightly  angled  from  the  vertical so when they press against  angled  surfaces  on the carrier housing sides, the  adapter  is  locked  to  the  carrier.  The contact frames  are  held  to  the housing to pivot thereon by a snap  ring  that  extends  around the four frames and is supported by the frames.

Title: Method and apparatus for aligning fiber optic cables
Inventor: SKURATOVSKY EUGENE
IPC: G02B6/38
Filed: 1988-03-04
Granted: 1992-09-29
Abstract: ABSTRACT         A duel cantilever beam member for aligning optical fiber cables is disclosed.  A first optical fiber cable is received through and attached to one end of the beam member while a second optical fiber cable is received through and attached to the other end of the beam member causing the ends of the optical fiber cables to be in close proximity to one another.  The dual cantilever construction of the beam member allows relative displacement of the one optical fiber cable with respect to the other optical fiber cable along only one co-ordinate axis and prevents relative displacement of the optical fiber cables along the other co-ordinate axes.  A chord shaped portion on the end of each optical fiber cable is blocked to define the transmission area between the cable ends and to increase displacement sensitivity of the device.

Title: Closed loop powder flow regulator
Inventor: GIANELLA EDWARD P
IPC: B05B7/14
Filed: 1988-06-16
Granted: 1992-09-22
Abstract: ABSTRACT     A powder feeding system, includes closed loop regulation of powder feed rate.  A feed gas is discharged under constant pressure into an enclosed hopper.  A valve is disposed to constrict a carrier conduit conveying powder in a carrier gas.  A load cell measures the rate at which powder is flowing from the hopper through an intake orifice into the carrier conduit, and a filtered flow rate signal is produced.  A first controller produces a reference signal representative of the difference between a set point signal and the flow rate signal.  A differential signal is produced corresponding to the pressure difference between the hopper pressure and a carrier conduit pressure taken between the intake orifice and the valve.  A second controller produces a control signal representative of the difference between the differential signal and the reference signal.  The valve is responsive to the control signal to proportionately constrict the carrier gas stream such as to regulate the powder flow rate.          Preferably the time constant of the second controller is faster than the time constant of the first controller.

Granted: 1991-06-25
Abstract: ABSTRACT OF THE DISCLOSURE      A low noise, high speed current transimpedance amplifier system (20) includes AC bootstrapping for the photodiode D1 by capacitor C2 connected between the source of the JFET Q1 and the cathode of the photodiode D1 by line (56).  Line (58) also provides AC bootstrapping to the case of the module (40) through capacitor C2.  Simi-larly, the source resistor R3 and drain of JFET Q1 are AC bootstrapped through capacitors C1 and C4 to the emitters of the transistors Q2 and Q4 by lines (60) and (62).  The collectors of the second stage transistors Q2 and Q4 are bootstrapped to the third stage transistors Q3 emitter through capacitor C8 by line (64).  This bootstrapping reduces the effective input capacitance at the front end of the amplifier system (20) by a factor of up to about 100, thus reducing signal noise component in the subse-quent stage or stages to negligible compared to front end noise.

Abstract: A DIGITAL VOICE SWITCH FOR A MULTI-PORT                CONFERENCE CIRCUIT              ABSTRACT OF THE DISCLOSURE    An echo cancellation arrangement is provided for decreasing the "singing" of a connection of a large number of telephone subscribers in a conference calling arrangement.  This arrangement includes a means for inserting quiet code during times when the voice samples of incoming PCM data are zero or below a predetermined minimum threshold level.  This helps decrease the amount of feedback which is amplified and output through the codec/filter to the listeners through the PCM network.  An attenuation arrangement is also included which decreases the level of a summed signal of a summing node of the conference circuit.          This sum signal is the combination of each of the conferees' speech.  Attenuation of this signal prohibits excessive coupling of amplified feedback to each of the listening conferees.
