Title: Vacuum-type sewage collecting apparatus
Inventor: ASANAGI TSUNEO
IPC: E03F7/00
Filed: 1990-08-27
Granted: 2000-06-27
Abstract: A vacuum-type sewage collecting apparatus arranged in such a manner that sewage discharged from the houses or facilities is once accumulated in a cesspool and the sewage accumulated in the cesspool is then collected in a predetermined portion through a vacuum valve and a vacuum sewage pipe the inner pressure of which has been made to be a negative pressure is disclosed. The vacuum valve being operated by negative pressure taken up from a vacuum source and supplied to the vacuum valve via a connecting pipe. The negative pressure for operating the vacuum valve is taken up from a vacuum sewage pipe portion which is elevated at a level higher than that of the vacuum valve in the down stream of the vacuum valve. Instead, the negative pressure may be directly taken up from an accumulating tank the inner pressure of which has been made to be a negative pressure by a vacuum pump, a pipe which establishes a connection between the accumulating tank and the vacuum pump or a tank connected to the pipe connecting between the accumulating tank and the vacuum pump. In this way, a high negative pressure can be supplied to the vacuum valve to effectively and completely open the vacuum valve to thereby perform efficient discharge of the sewage through the same valve.

Title: Timing apparatus
Inventor: MARSH MICHAEL JOHN CAMILLE
IPC: F42D1/055
Filed: 1990-09-26
Granted: 1997-03-25
Abstract: The  invention  relates  to  a  blasting  apparatus  for activating a plurality of electrical detonators after predetermined  time  delays. The  blasting  apparatus includes a plurality of remote electrical delay devices. Each device is linked to a detonator, and is arranged to be  serially programmed with a  timing  signal,  which originates  from the central  control  unit  and which determines  the  time delay.   A bidirectional  signal harness, having ends which terminate at I/O ports in the control unit, serially links the delay devices to the control unit.  In the event of a fault of discontinuity occurring in the harness prior to programming of the delay devices,  the discontinuity is detected and the direction of programming along the bidirectional harness is reversed so that those delay devices which, due to the break, cannot be programmed in the initial direction, are programmed with timing signals travelling along the signal line in the opposite direction.   The invention extends  to  a  method  of  activating  a  plurality  of electrical detonators, as well as to the individual delay devices forming part of the blasting apparatus.

Granted: 1994-04-05
Abstract: BURST TIME DIVISION MULTIPLEX INTERFACE FOR       INTEGRATED DATA LINK CONTROLLER               ABSTRACT OF THE DISCLOSURE     Subject  burst  time  division  multiplex  interface connects  circuits  which perform  "layer  1  (L1)"  line control  functions  relative  to  a  data  communication network with devices which perform "Layer 2 (L2)" link control functions relative to the same network (L1 and L2 defined  by  OSI  Specifications  of  the  International Standards Organization). The interface is characterized by presentation of bursts of readiness indicating pulses from the L1 circuit to the L2 device during each basic time division multiplex time slot. The pulses indicate readiness  of the  circuits  for data bit  exchange,  and separate  time  overlapped bursts  are  sent  to  indicate readiness of the circuit to send and receive data bits. Each burst contains a varied number of pulses ranging from O to n (where n is greater than 2,  and in the disclosed embodiment equals 8). The bursts are positioned in a womdpw of time occupying a fraction of the slot interval close to the emd of each slot. This allows the L2 device to perform state swapping operations during the remainder of the slot to prepare for burst exchanges with different  network  channels  to  which  the  slots  are allocatable ant to be able to devote maximum processing time to performance of L2 tasks required relative to the channels.    The   channels    operate   under   various communication protocols (HDLC, LAP-D, clear/voice, etc.). Slot time spacings are variable by the L1 circuits to adjust to signalling conditions in the network.
