Title: Split drive sprocket for a conveyor belt
Inventor: HARVEY JOHN
IPC: F16H55/46
Filed: 1999-05-14
Abstract: A sprocket of the type typically used for driving a plastic conveyor belt is split through the drive shaft hole at its center, so that the sprocket can be assembled over a drive shaft without disrupting the conveyor assembly. Two sections which form the drive shaft preferably are identical, and may be machined from high molecular weight polyethylene. In a preferred embodiment the two sections are assembled together by interlocking features shaped as jigsaw puzzle pieces. The two sections are placed against the drive shaft and are moved together in the axial direction of the drive shaft, thus sliding the sections together. One or more fasteners may be provided at easily accessed locations to permit the two sections from sliding apart.

Title: Direct manipulating direct-graduated release cap for 26-type control valves
Inventor: KUSHNIR LAWRENCE M JR
IPC: B60T15/04
Filed: 1999-05-27
Abstract: A direct acting release cap for air brake control valves in trains which will allow for the manipulation of the valve characteristics from a direct brake release to a graduated brake release without removal of the cap from the body of the valve. This is accomplished through longitudinal movement of a spool, which directs internal air passages that control valve characteristics. The present invention eliminates the requirement of removing the direct acting release cap from the valve in order to change the working characteristics of the valve, thus resulting in a time savings for the operator.

Title: Method for identifying the direction of rotation of a wheel by means o f hall probes
Inventor: DRAXELMAYR DIETER
IPC: G01P13/04
Filed: 1998-04-23
Abstract: The invention relates to a method for detecting the direction of rotation of a wheel (8) by means of Hall probes (14 to 16) arranged in the peripheral direction of the wheel (8). A first, second and third hall probe (14 to 16) are positioned in succession so that the second Hall probe (15) lies between the first and third Hall probes (14, 16). The output signals (51, 52, 53) of the three Hall probes (14 to 16) are used to obtain two evaluation signals.  Said evaluation signals are then compared to determine the direction of rotation of the wheel (8). The first evaluation signal is obtained by substracting the third output signal from the first output signal. The second output signal is obtained by adding the first and third output signals and substracting twice the value of the second output signal.

Abstract: The towel design is a method to provide convenience for those who will frequent a beach, campsite or Gym. All that will be needed should a person go to the above said destinations is just to carry their towel. All their belongings do not have to be carried in a tote bag or purse but securely sealed in their own towel. In this invention, there are pockets, which are sewn onto the towel in the four corners of the towel. The material, which is used, is of the same texture and color of the said towel. Inside two of the four pockets are two smaller pockets which are used to help secure valuables such as wallet, hotel key, cellular phone, jewelry etc. All four pockets are closed and secured with a zipper. There is a plastic seal inside each of the six pockets, rendering them waterproof. At the head of the towel, there is a slide pocket (no zipper, no seal) which can be used as a pillowcase to stuff T-shirts or any article of clothing. The pockets at each end of the towel will secure the towel in its place using the weight of the articles placed inside to prevent the wind from blowing the towel away.  Belongings are also kept secure since on the face up of the towel, the pockets are not visible.

Patent CA-2306048-A1 (CA)
Inventor: FUKUMOTO ATSUSHI
IPC: G11B11/105
Filed: 2000-04-18
Abstract: A DWDD type data reproducing apparatus which handles a magneto-optical recording medium having a magnetic three-layer film consisting at least of a displacement layer, a switching layer and a memory layer.      A magnetic wall displacement in the displacement layer is generated in any region where the temperature of the magnetic film becomes higher than the Curie temperature of the switching layer, so that the effectively recorded magnetic domain is dimensionally enlarged. A reproduced signal is first equalized with regard to its waveform in an equalizer circuit and then is supplied to a magnetic wall displacement detection circuit. In this detection circuit, a detection signal representing generation of a magnetic wall displacement is produced by using a differential signal or a secondary differential signal of the reproduced signal without being harmfully affected by any sudden DC level variation caused in the reproduced signal. Subsequently a data detection circuit detects the data by the use of such detection signal and then outputs the reproduced data. In this apparatus, the data can be reproduced at a sufficiently low bit error rate despite occurrence of any sudden DC level variation caused in the reproduced signal.

Title: Load based priority for the mobile subscriber
Inventor: BORG GUNNAR
IPC: H04W72/10
Filed: 1998-10-08
Abstract: A "load based priority" telecommunications system and method which provides efficient use of Traffic Channels (TCHs), while both meeting the subscriber's needs and producing revenue for the cellular operator. "Load based priority" for the mobile subscribers consists of assigning a priority to the subscriber at the time of service activation.  The subscriber can pay a low rate for lower priority subscriptions and a higher rate for higher priority subscriptions. The system continuously checks the traffic load on the TCH and broadcasts the current priority in the system information message to the mobile stations in the cell.  For example, if the system broadcast message reads low priority, then all mobile subscribers will be able to make calls. However, if the system broadcast message reads high priority, then mobile subscribers who have purchased a lower priority subscription will not be able to make calls.
