Title: Connection release in a telecommunications system
Inventor: CHOTAI SUNIL
IPC: H04M3/48
Filed: 1995-05-26
Granted: 1999-11-16
Abstract: In a telephone network, e.g. a cellular radio system, after a transaction (e.g. a call) has ended, the connection is not fully released. If another connection is to be setup on ending of a current call, e.g. a voice message or call completion to be a subscriber arrangement, a flag (F) is set in the connection management system (CM). The status of the flag (F) is used to determine if the signal in connection towards a termination (B) should be kept or released immediately. Depending on the status of flag (F) different actions are taken in the network. The connection may be maintained for a predetermined interval. Data (F, F1, F2), concerning the status of the flags are transmitted from switching centre (MSC1) to another switching centre (MSC2) if control of the network termination is transferred. If control of the network termination (B) passes to a switching centre not capable of supporting the service to which the flag (FI) relates, the flag status is stored in a buffer register (HLR) associated with the user until such time as it is again connected to a switching centre capable of supporting the service.

Abstract: A water adding control apparatus includes a microwave detecting unit which enables the detection of microwave value proportional to the water content amount of the water added grain and which makes it unnecessary to make calculations for an estimated water content value of the water added grains.  The water adding process is started by inputting initial water adding amount, the microwave value of the raw grain after the addition of water is measured, the measured microwave value is set as the target microwave value which serves as control reference, and the water adding amount is feed-back controlled for the actually measured microwave value to constantly match the target microwave value.

Title: Ready-to-wire circuit breaker
Inventor: HUDSON RICHARD H II
IPC: H01H71/08
Filed: 1998-03-25
Granted: 2008-05-13
Abstract: A circuit breaker terminal (18) has an attachment screw (20) pre-assembled to an "open position" enabling an installer to insert a wire without having to loosen and back out the screw. After a wire has been inserted, the installer tightens the screw into forceful engagement with the wire to secure the wire to the load terminal. The attachment screw shank (20s) has an irregularity (38) that is located along a segment of the screw thread that lies between proximal and distal ends of the screw thread (34) and that interrupts the uniformity of the screw thread. This irregularity is disposed in interaction with a through-hole (28) in the terminal when the screw is in open position to create a resistance to turning of the screw which sufficiently exceeds the resistance to turning encountered when a portion of the screw thread immediately contiguous the irregularity is threaded into the through-hole. The irregularity maintains its interactivity with the through-hole to keep the screw in open position until the screw is turned by an installer at time of installation.
