Title: Automated transaction machine with sheet accumulator and presenter mechanism
Inventor: HANEY SEAN
IPC: B65H5/06
Filed: 2001-09-27
Abstract: An automated transaction machine (600) includes a note receiving storage and dispensing mechanism (624). The mechanism (624) includes a stacker mechanism (654). The stacker mechanism collects in a stack notes such as currency bills that are to be dispensed from the machine to a user, and the stack is then presented to the user from the machine. The stacker mechanism includes a stack support member (668), a flexible member (692) and spaced supports (694). Notes are engaged in supporting connection with the stack support member as the stack support member is rotated in a first rotational direction. After the stack is accumulated, rotation of the stack support member in an opposed rotational direction delivers the stack from the stacker mechanism.

Patent CA-2422047-A1 (CA)
Inventor: CONNELL ROBERT GERALD
IPC: A01K1/01
Filed: 2001-09-13
Abstract: A disposal system (10) for animal waste includes a housing /12) having upstanding walls (16, 18) defining an entranceway and a floor (14) which slopes downwardly and rearwardly from a forward edge at the entranceway (22) to a rear edge (26). A collection groove or trough (30) extends transversely of the floor at the rear edge and is provided with a bottom surface which slopes downwardly to a disposal pipe (34). The pipe in turn is connected to an electrical pump which is adapted to move waste from the collection groove to a sewer. Preferably the pump is provided with macerator blades which will macerate or comminute the solid waste to improve its flowability to the sewer.  The floor is provided with a plurality of generally parallel grooves (28) in the upper surface thereof, which grooves collect liquid waste and allow it to flow downwardly to the collection groove without much liquid remaining on the upper surface of the floor. With this invention the animal will not be stepping in its own liquid waste after urination and there will be little or no liquid waste tracked by the animal after it leaves the housing. The pump and a separate flushing system, which can operate automatically after the animal has relieved itself, ensure a quick removal of liquid and solid waste from the housing, leaving the housing fairly clean and odor-free.

Patent CA-2427943-A1 (CA)
Inventor: SUNDAR RANGAMANI
IPC: H04W88/18
Filed: 2001-11-21
Abstract: A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. Besides providing an ability to offload mobile traffic it provides a platform for new communication services. The proxy switch includes signaling message handling logic that receives signaling messages from the MSC  and BS in accordance with a mobile signaling protocol. State logic maintains state information of call sessions and mobile stations (MSs) used within the mobile communications network. Message interception logic detects whether a signaling message from an MSC is a new call originating message and if an MS  addressed in such a new call originating message is involved in a call. The message interception logic also prevents the new call originating message from being forwarded to the BS servicing the addressed MS. Message conversion logic converts the new call originating message to a feature notification message, and message transmission logic issues the feature notification message to the BS servicing the addressed MS.

Filed: 1999-11-25
Abstract: In this speech encoding system, the limiter circuit is input with the delay of adaptive codebook obtained for the previous subframe, and the pitch cycle search range is limited so that the delay of adaptive codebook obtained for the previous subframe is not discontinuous to the delay of adaptive codebook to be obtained for the current subframe, and the pitch cycle search range limited is output to the pitch calculation circuit. The pitch calculation circuit is input with output signal X w (n) of the perceptual weighting circuit and the pitch cycle search range output from the limiter, calculating the pitch cycle T op, then outputting at least one pitch cycle T op to the adaptive codebook circuit. The adaptive codebook circuit is input with the perceptual weighting signal x'w (n), the past excitation signal v(n) output from the gain quantization circuit, the perceptual weighting impulse response h w (n) output from the impulse response calculation circuit, and the pitch cycle T op from the pitch calculation circuit, searching near the pitch cycle, calculating the delay of adaptive codebook. With the above composition, the delay of adaptive codebook obtained for each subframe can be prevented from being discontinuous in the process of time.

Title: Tractor with improved valve system
Inventor: BLOOM DUANE
IPC: E21B23/00
Filed: 2001-12-03
Abstract: A hydraulically powered tractor includes an elongated body, two gripper assemblies, at least one pair of aft and forward propulsion cylinders and pistons, and a valve system. The valve system comprises an inlet control valve, a two-position propulsion control valve, a two-position gripper control valve, two cycle valves, and two pressure reduction valves. The inlet control valve spool includes a hydraulically controlled deactivation cam that locks the valve in a closed position, rendering the tractor non-operational. The propulsion control valve is piloted on both ends by fluid pressure in the gripper assemblies. The propulsion control valve controls the distribution of operating fluid to and from the propulsion cylinders, such that one cylinder performs a power stroke while the other cylinder performs a reset stroke. Each end of the gripper control valve is piloted by a source of high-pressure fluid selectively admitted by one of the cycle valves. The gripper control valve controls the distribution of operating fluid to and from the gripper assemblies. The cycle valves are spring-biased and piloted by fluid pressure in the propulsion cylinders, so that the gripper control valve shifts only after the cylinders complete their strokes. The pressure reduction valves limit the pressure within the gripper assemblies. These valves are spring-biased and piloted by the pressure of fluid flowing into the gripper assemblies. Some or all of the valves include centering grooves on the landings of the spools, which reduce leakage and produce more efficient operation. The propulsion control and gripper control valves include spring-assisted detents to prevent inadvertent shifting.
