Abstract: An operating mechanism for a manually operated load break switch having an over center spring drive moved by an operating handle to open and close the switch.  The operating mechanism includes a shaft rotatable by the operating handle, a follower rotatably mounted on the shaft, an elongated forked plate pivotally mounted intermediate its length to the follower at a location radially outwardly of the shaft, an operating lever for the switch pivotally mounted on the shaft and movable by engagement with the follower and a driver affixed to the shaft for rotation therewith and positioned to engage and rotate the follower and the forked plate.  An over center spring drive is pivotally connected to the forked plate at a location radially outwardly of the pivotal mounting of the forked plate to the follower.  This mechanism permits the over center spring drive to be moved between fully closed and fully opened conditions of the switch by rotation of the operating handle while preventing alignment of the shaft, the pivotal mounting of the forked plate to the follower and the over center spring drive pivotal mounting to the forked plate when the spring drive reaches its fully compressed condition.

Title: Method and device for measuring an electrical alternating quantity with temperature compensation
Inventor: BOSSELMANN THOMAS
IPC: G01R15/24
Filed: 1994-09-22
Granted: 2000-11-14
Abstract: Method and device for measuring an electrical alternating quantity with temperature compensation In a sensor element (3), the polarization of polarized measuring light (L) is changed as a function of the alternating quantity (X). After passing through the sensor element (3), the measuring light (2) is split into two differently linearly polarized partial light signals (LS1, LS2), which are converted into electrical intensity signals S1 and S2. An intensity-normalized signal P = (S1-S2)/(S1+S2) is then formed. A temperature-compensated measured signal S = (a*PAC+b*1)/ (c*PDC +d*1) is derived from the alternating signal component PAC and the direct signal component PDC of this intensity-normalized signal P. The temperature sensitivity can thus be reduced by a factor of 10.

Title: Incoming call control for wireless sets
Inventor: CHAVEZ DAVID LEE JR
IPC: H04Q1/30
Filed: 1996-11-06
Granted: 2001-02-13
Abstract: A PCS switching system and wireless set that allow the wireless set to control the processing of incoming calls regardless of whether the base station on which the wireless set is registered has capacity to complete a call to the wireless set. When an incoming call is received for a wireless set, a central computer providing overall control of the PCS system directs this call to a paging zone controller of a paging zone in which the wireless set is registered on a base station. If the base station does not have capacity to handle that call, the paging zone controller transmits a page pending message via the base station and a paging channel to the wireless set informing the wireless set that a page is pending and that the wireless set must find a base station with idle capacity. If the wireless set cannot find a base station with idle capacity within the paging zone, the wireless set transmits to the PCS switching system via the paging zone controller a page pending response message that specifies the operations that the PCS system is to perform with respect to the incoming call. The wireless set can specify the call coverage system to which the incoming call is to be routed. In addition, The wireless set can specify a message that will be given to the calling party of the incoming call by the call coverage system. The wireless set can specify that the incoming call is to be placed on hold until the wireless set can find a base station having call capacity to complete the incoming call to the wireless set.

Abstract: A caulking gun and cartridge combination is provided with afterflow prevention. The cartridge has a tubular body (8), a forward dispensing opening (9) at a forward end of the tubular body, and a backwall (11, 12) movably disposed within the tubular body (8). The caulking gun has a trough (1) for receiving the cartridge, and a piston (4) movable parallel to the trough (1).  A trigger handle (23) is used for pushing the backwall (11) forward within the tubular body and causing a reduction of volume within the chamber (13) in the cartridge. The backwall slides substantially in a contact-less manner within the tubular body, preferebly by way of a reduced diameter (OD) of the backwall (11) relative the inner diameter (ID) of the tubular body (8), so that it is pushed backwardly when the body retracts radially after actuation.  Alternatively, the cartridge body may be prevented from expanding or may even be actively squeezed so that afterflow caused by the volume reduction of the relaxing tube body is safely prevented.

Title: Temporary frame identification for arq in a reservation-slotted-aloha type of protocol
Inventor: TURINA DALIBOR
IPC: H04B7/26
Filed: 1996-04-10
Granted: 2007-06-26
Abstract: Automatic repeat request (ARQ) functionality in a cellular mobile packet data communication system using a reservation slotted-ALOHA protocol is provided by assigning a temporary frame identity (TFI) to each data frame transmitted to or from a mobile station. The assigned TFI is unique among concurrent frame transfer sequences in a cell, and may be assigned based on information in a data frame sent to the mobile station or based on information in a channel reservation message that precedes the data frame sent to the mobile station. The TFI may also be assigned based on information in a channel reservation message that precedes a data frame sent from the mobile station, and the TFI assigned is unique among concurrent frame transfer sequences in a cell. The TFI is included in every block belonging to a particular frame, a block being the unit of data on which ARQ is based. A partial data frame to be retransmitted in case of a transmission error contains only the blocks determined by the ARQ protocol type (e.g., selective or Go-back-N) used, whereby a primary block need not be added to identify the mobile station. Blocks belonging to frames destined for different mobile stations can be multiplexed on the downlink based on the TFI. The mobile station may include, in its random access request, an indication that a TFI is already assigned.
