Title: Constant contact side bearings
Inventor: LIST HAROLD A
IPC: B61F5/14
Filed: 1993-12-29
Abstract: Constant contact side bearing support of a rail car body on a multi-axle rail car truck is provided for controlling car rocking. A bearing receiver or cage (26) mounted on the truck bolster (9) in laterally offset relationship to the truck center plate bowl (22) supports wedge shaped bearing blocks (32) on inclined surfaces (27, 28) within the cage (26). A long travel coil spring (38) biases the bearing blocks (32) against the inclined surfaces (27, 28) of the cage (26), thereby maintaining a substantially constant normal bearing force on the car body throughout the wear life of the bearings. In an alternative embodiment, the cage (26) is mounted on the car body with the bearing surfaces (35) of the bearing blocks (32) engaging corresponding bearing surfaces on the bolster (9). Arrangements providing for ease of inspection and replacement of the bearing blocks are disclosed.

Inventor: MARUTIAK DAVID JAY
IPC: H04M1/2747
Filed: 1995-08-28
Abstract: A method and apparatus for automatically and dynamically determining a list of frequently called telephone numbers for abbreviated dialing or speed dialing. The method and apparatus maintain a list of each telephone number dialed, either manually or by abbreviated dialing, over a period of time. This list is periodically updated to remove infrequently used telephone numbers. The list is also sorted such that the most frequently used telephone numbers will be displayed as a top set or page thereof. The apparatus includes a telephone set which has multiple display areas where one set or page of telephone numbers available for abbreviated dialing is displayed. Each display area is associated with and adjacent to a respective switch. A paging switch which causes the display of one or more subsequent sets or pages of the abbreviated dialing list may also be included. To make a telephone call using the abbreviated dialing apparatus, the user actuates the switch adjacent to the display area displaying the frequently dialed number or a label (name) corresponding to the frequently dialed number. From that switch actuation, the apparatus will read the corresponding number to be dialed from memory and automatically dial the number. This abbreviated dialing list is self starting and self maintaining, the user never needs to personally 'program' the telephone set. This method apparatus may include the use of a customer premise equipment and/or a telecommunication switch.

Title: A valve actuated by its own medium
Inventor: KALIN RUDOLF
IPC: F16K31/42
Filed: 1995-11-20
Abstract: The valve comprises a first pressure chamber (2), an outlet chamber (6) and a valve body (8), cooperating with a first valve seat (12), and also a second pressure chamber (13) delimited by the valve body. The valve body (8) comprises a control piston (22) which cooperates with a second valve seat (26) and is movable between a closing position and an open position. The control piston delimits in a valve chamber (17) a first sub-chamber, which faces away from the second valve seat (26) and communicates with the first pressure chamber (2), a second sub-chamber, which faces the second valve seat (26) and communicates with the outlet chamber (6), and a middle sub-chamber, which surrounds the cylindrical surface of the control piston and communicates with the second pressure chamber (13). The control piston (22) establishes in the closing position transfer communication between the first and the middle sub-chamber, and in the open position transfer communication between the second and the middle sub-chamber. The valve body (8), which is designed as an equalizing piston, adjusts itself always like a follower piston with respect to the control piston (22) which may be driven by a controllable positioner (19), and is controllably displaceable thereby between the first valve seat (12) and the various open positions.

Patent CA-2167488-A1 (CA)
Title: Automated, fault tolerant, zone sector mark generation method
Inventor: CULLEY MARTIN L
IPC: G11B27/19
Filed: 1994-08-03
Abstract: The present invention includes a method, apparatus and disk format for implementation of the same to provide fault tolerant detection of ID fields for data sectors in order to eliminate errors caused by mis-alignment and mis-detection of hard sector marks. Logic is provided to initiate a time-out count at the completion of a hard sector count. The time-out count is specified to be a period of time-within which a hard sector mark should be detected. If the time-out count counts down and a hard sector mark is not detected, then a possible error situation arises and the fault tolerant process is initiated to compensate for the lack of detection of a hard sector mark. Thus, at the end of the time-out count, a small burst count is started. This small burst count is of a shorter duration than the original burst count utilized, but is long enough to bring the head assembly to the location in the sector at the beginning of the user data at which time the hard sector count is initiated to count down the user data locations for that hard sector. Thus, the beginning of the user data area will always be determined and errors due to ill-defined user data areas caused by mis-detection of a hard sector mark are avoided.

Title: Charge recording in a telephone network
Inventor: HACHENBERGER ANDREAS
IPC: H04M15/32
Filed: 1995-07-12
Abstract: Described is a process for the transmission of charge information to the subscriber switch-in equipment and for the output of charge pulses at the a/b interface of the subscriber switching equipment in a local communications and transmission system which is organized  as a local radio cell comprising a central fixed radio site and a plurality of decentralized subscriber switch-in devices and is connected to the public telecommunications network as a local exchange office or as a private branch exchange facility. According to the invention, a distance zone table which is adapted to the location is stored in the base station of every radio cell and contains the time clock information for charge accounting for the local zone and all communications outside the local zone, and the telephone number dialed by a radiotelephone subscriber is automatically compared with the distance zone table during the ongoing communication of the radiotelephone subscriber, the applicable time clock information is obtained and transmitted to the subscriber switch-in equipment which generates standard charge pulses corresponding to the transmitted time clock and gives out this information at the a/b interface. The standard charge pulse of 12 kHz or 16 kHz cannot be transmitted over radio channels whose transmission bandwidth is restricted to the voice band from 300 Hz to 3400 Hz. As a result of the applied solution, in contrast to conventional processes, the charge pulse need not be transmitted as a substitute signal which is embedded in the voice band and which would cause interference in the transmission of signals from modems and facsimile devices as experience has shown.

Abstract: The  invention  relates  to  a  protective  device  for  a driveshaft 1.  For fixing the protective device on a joint yoke 4 of a universal joint 2 there is provided a connecting cap 9 in connection with a sliding ring 10.  Furthermore, the connecting cap 9 serves to connect the protective cone 12.  The protective cone 12 comprises a fixing portion 16 by means of which it is fixed on the connecting cap 9 by means of one or several resilient locking elements 22 which are connected to the sliding ring  10.    The  resilient  locking  elements  22  permit  the protective cone 12 to be axially slid on to the connecting cap 9 without requiring any additional auxiliary means.  However, they can only be opened by deliberately actuating at least one locking element by means of a tool, for example for making the joint 2 covered thereby accessible for maintenance purposes.
