Abstract: A semirigid swim cap (100) is disclosed, having a unitary construction. The swim cap is generally open at the bottom and includes a forward edge (104), a rearward edge (106), oppositely disposed ear cover portions (108), and a center portion (101). In a preferred embodiment, the swim cap is made from an elastomeric thermoplastic and the center portion is relatively thick, while the peripheral edge portions are relatively thin and therefore less rigid. A pair of sealing ridges (110) extends from an inner surface of the swim cap, near the open bottom.

Abstract: A screening assembly 10 includes at least one rail 14 to be secured to a support member of a screening machine to lie parallel to, and intermediate, side members of the screening machine. At least one locating formation 18 stands proud of an operatively upper surface of each rail 14. The assembly includes a plurality of screening modules 12. Each screening module 12 has an end supported on the rail 14 so that a pair of modules 12 lie in end-to-end abutting relationship with the abutting ends, in use, overlying the rail 12 and defining a receiving formation through which the locating formation 18 protrudes to project beyond the receiving formation into a recessed region defined by the abutting ends of the pair of modules 12. A locking member 46 is associated with the receiving formation and is receivable in the recessed region for engaging its associated locating formation to lock the pair of modules with respect to each other and with respect to the rail 14.

Abstract: This invention relates to a communication apparatus (203) and method of format adaptation particularly suited for a CDMA cellular communication system. A transmitter (211) transmits a signal to a communication apparatus (203) using a specific transmission format. The transmission includes transmission format information allowing the receiver (217) to adapt to the current transmission format. A hybrid scheme is adopted where transmit format information needed for symbol information is generally transmitted in a transmission block prior to the one where it is applied whereas transmit format information relevant to processing of the demodulated symbols is transmitted in the same transmission block to which it applies. The communication apparatus (203) thus comprise adjustment means (223) operable to adjust a characteristic of the current or future transmission blocks in response to the received transmission format information. The invention is applicable to the UMTS mobile cellular communication system.

Abstract: An electric drive system is provided to generate varying amounts of output torque supplied to a driven member over a wide range of constant revolutions per minute speeds to reduce power consumption. The electric motor includes a rotor and a stator assembly. The stator assembly is disposed around the rotor and is inductively coupled to the rotor. The stator assembly further includes a plurality of poles, each pole consisting of a plurality of split windings wound so that the magnetic fluxes generated therefrom are added. Power switching circuits are provided for energizing the partition drives of split windings on each of the stator poles. A controller is used to selectively control the frequency, pulse width modulation, and partition configuration to vary the rotational speed and torque generation supplied to the driven member.

Abstract: Inserting operational data onto a magnetic disk allows information to be transferred from a servowriter station to a verifier station. This operational data allows disk specific operational data to follow the disk without separate means for attaching data to each disk. The servowriters, which cannot write information to disks at the data sector frequency, inserts the operational data into selected greycodes in the servo sectors. When the disks are verified, the operational data may be moved from the servo sectors to the data sector in the Z-tracks for more permanent storage.

Abstract: A fractional-power electric motor is provided to generate varying amounts of output torque supplied to a driven member over a wide range of RPM speeds so as to reduce power consumption on a battery-powered source. The electric motor includes a rotor and a stator assembly. The stator assembly is disposed around the rotor and is inductively coupled to the rotor. The stator assembly further includes a plurality of poles, each having a main winding and at least one fractional-power winding. The main winding and associated at least one fractional-power winding on each of the stator poles are wound so that the magnetic fluxes generated therefrom are added. Power switching circuits are provided for independently energizing the main and fractional-power windings on each of the stator poles. A controller is used to control selectively the frequency and duty cycle energization of the power switching circuits to vary the rotational speed of the rotor and the amounts of torque supplied to the driven member.

Abstract: A servicing arrangement is provided for a conveyor belt cleaner. The servicing arrangement includes an elongate mandrel member having a first end and second end. The second end of the mandrel member is adapted to be attached to a support such that the mandrel member is retained by the support in a cantilevered manner. A support member is adapted to be positioned over the mandrel member by sliding the support member over the first end of the mandrel member. The support member is selectively slidable along the mandrel member to selectively remove or selectively mount the support member on the mandrel member. The support member is adapted to receive and support a conveyor belt cleaner. An operator can easily remove the conveyor belt cleaner from the mandrel member for service or replacement of the conveyor belt cleaner from the outside of a conveyor housing during conveyor operation when a suitably designed tensioner with a release mechanism is used to protect the operator from cleaner blade pull through.

Abstract: An airless hand held hydraulic pump unaffected by gravity continuously maintains pressure on the fluid in a dynamic reservoir chamber to enable pumping into a dynamic pressure chamber for actuating a forcing rod irrespective of the orientation of the pump. A release valve permits fluid return from the pressure chamber into the reservoir chamber. The pump can be fitted with a tool such as a door forcer.

Abstract: A head-mounted, hat-like device includes components for guiding a stream of air flowing in a direction frontwardly of the face of the user and filter components for filtering the stream of air. The air flow guiding components include a fan fixedly mounted to a housing, a directional member mounted to the visor portion of the housing for directing air frontwardly of the person's face and a conduit for interconnecting the directional component and the fan device. The fan device draws ambient air including smoke and other by-products of burning tobacco through the directional component and along the conduit to be discharged by the fan device through a conventional tobacco by-product filter component, thereby cleansing the stream of air before it is released to the air space above the person.
