Title: Overload clutch unit
Inventor: KEMPERS FRIEDHELM
IPC: F16D43/21
Filed: 2000-02-18
Abstract: A clutch unit 1 for the drives of mining and conveying devices, comprises a first clutch half 2 on the driving side, and a second clutch half 3 on the driven side, and a multi-plate clutch 4 which rotatably connects the two clutch halves. The clutch plates 4 are pressed against each other with frictional engagement, for the transmission of torque, by means of an annular piston 5 which can be acted upon by a pressure medium. One or more clutch springs 6 for storing the clutch force set by means of the annular piston are associated with the clutch plates 4 on the side thereof facing the annular piston. There is no disengagement of the clutch halves. Instead, overload protection is made possible by the elastic storage or transmission of the clutch force by means of the clutch springs, to allow the clutch halves to rotate relative to each other.

IPC: D21F11/00
Filed: 2000-04-04
Abstract: The invention relates to a paper machine clothing, notably an air-dry clothing (TAD clothing), in the form of a woven having a weaving design. According to the invention the relative depth of machine clothing cups which are open towards the contact surface of the paper is 20 % or more, said relative cup depth being the quotient of the difference between the measurement height for which the bearing percentage is 30 % and the measurement for which the bearing percentage is 60 %, on the one hand, and the sum of the diameters of a warp thread and a weft, on the other hand. The measurement height "0" is the outer limit of the paper machine clothing on the paper contact surface, the bearing percentage is the projected sectional area of the threads of the woven at a given measurement height in relation to the measurement surface, the sectional areas being parallel to the surface of the clothing. The invention also relates to a tissue paper product which is produced with such a clothing and is especially voluminous in direction Z.

Title: Converting user frames to network frames, wherein user frame address information is ignored when determining the destination address of the network frames
Inventor: FURUKAWA HISAO
IPC: H04L29/12
Filed: 1997-10-17
Abstract: An integrated communications system (ICS) 1 has access control apparatuses 2-7, which serve as access points for LANs. ICS user frames 80, 82, having different unique ICS user address systems ADX, ADY, can be converted into ICS network frames 81, 83 with address system ADS, using conversion tables in the access control apparatuses 2-7. The network frames are transmitted via value added networks (VANs), following the rules of the internal address system ADS, to reach destination addresses in networks with user address systems ADX or ADY. An identification number may be registered in the conversion table to identify the mode of communication as intra-corporation (the sending user and the receiving user use the same address system), inter-corporation (the sending user and the receiving user use different address systems), or 'virtual dedicated line'. The present application is concerned with the 'virtual dedicated line' mode, in which the destination address of the network frames is determined independently of address information contained in the user frames, the destination address being preregistered in the conversion tables.

Title: Fault tolerant magnetoresistive solid-state storage device
Inventor: JEDWAB JONATHAN
IPC: G11C11/15
Filed: 2002-07-04
Abstract: A magnetoresistive solid-state storage device (MRAM) performs error correction coding (ECC) of stored information. At manufacture or during use, each logical block of ECC encoded data and/or the corresponding set of storage cells are evaluated to determine suitability for continued use, or whether remedial action is necessary. In a first preferred method ECC decoding is attempted to determine whether information is unrecoverable from the block of ECC encoded data. In a second preferred method a parametric evaluation is made prior to attempting ECC decoding.

Title: Operation of a vending machine using a cellular phone
Inventor: MACKAY GEORGE
IPC: H04L29/06
Filed: 2002-10-18
Abstract: A cellular phone payment system for making payment for goods or service, which comprises three parts: 1) a user's cellular phone, which could also be any other form of mobile communications device provided that it can be linked to the public phone system, 2) an on-street vending machine, and 3) a remote payment auto-attendant computer with modem, which can be accessed by the public phone system. The user's cellular phone is the communications link or conduit used to access the remote payment auto-attendant computer; as well as to relay instructions to the user once user verification has been completed. The user calls the auto-attendant, authenticates his/her identity, and then is given instructions on how to make remote cellular payment on the vending machine in question. The user follows the instructions, which consists of indicating what good/service is being purchased, and then entering a sequence of challenges and responses between the remote auto-attendant computer and the vending machine to validate and confirm payment on the machine. The user uses the phone keypad and the keypad on the vending machine as the data entry means. Once the payment cycle is successfully completed, the payment will have been securely authenticated, the good/service provided, and the users preferred payment method, has been debited the corresponding amount. The payment will have been accomplished with the vending machine offline.
