Patent CA-2221072-C (CA)
Inventor: O'DONOVAN TIM
IPC: B23B39/16
Filed: 1997-11-13
Granted: 2000-12-19
Abstract: An apparatus for drilling holes in multiple pieces of lumber of uniform width and which is capable of processing more than one width is disclosed. The drill bits are arranged in rows and the spacing between drill bits differs from row to row so as to permit the drilling of holes in more than one size of lumber. The header in which the drill bits are mounted is adapted to travel vertically along two parallel guides. Stabilizers prevent the lumber from buckling or shifting and help to ensure that the holes will be drilled in the same location in each piece of lumber. When a layer of lumber is conveyed to the apparatus, pistons lower the header which brings a spring-loaded horizontal stabilizer into contact with the lumber to stabilize the lumber. A second stabilizer pushes the lumber laterally to press the pieces of lumber together. The drill bits then penetrate the lumber after which the drill bits are retracted from the lumber, the lumber is removed for stacking, a fresh layer of lumber is conveyed to the apparatus and the process is repeated. A method for drilling holes in dimensional lumber is also disclosed.

Title: Downlink beam forming architecture for heavily overlapped beam configuration
Inventor: JEFFRIES ANDREW WILLIAM
IPC: H01Q3/26
Filed: 1998-02-23
Granted: 2002-04-16
Abstract: An antenna beam forming means for generating a plurality of broad overlapping radiation beams for a cellular radio application comprises an antenna array (900) having a plurality of individual antenna elements (901-904), each individual antenna element connected by a cable to a respective diplexor (905-908), each diplexor fed by a multi-channel power amplifier (909-912) receiving an input from an output port of an eight way Butler matrix (913). Transmission signals are input to seven input ports of the Butler matrix, and output transmission signals are produced at four of the output ports of the Butler matrix. A remaining four output ports are each terminated with a respective matched load(939-942). A 3dB power loss incurred in the Butler matrix is compensated by provision of a plurality of pre-amplifiers (920-926) prior to the input ports of the Butler matrix, with the power amplification stage being carried out on the outputs of the Butler matrix. Side lobe suppression is maintained by ensuring phase and amplitude integrity across the output channels. A set of phase and amplitude adjusters (927-930) operate on the output transmission signals from the Butler matrix output ports. The phase and amplitude adjusters may be electronically controlled.

Abstract: A container is made in two stages from thermoplastics material. In the first stage a preform (1) is injection moulded, the mould parts easily releasing a tubular body (2) with a closed end and an outwardly projecting rim (3) at the open end. In the second stage the still heated preform (1) is blow moulded, possibly with some preliminary mechanical stretching, with the blow pin (13) seated in the open end of the body (2) and the preform (1) held by the outer part (7) of its rim. The wall of the body (2) is expanded, and immediately below the open end it is stretched outwardly to meld with the underside of the inner part (5) of the rim. The resultant container thus has a mouth defined by an inset lip.It may be of paint tin form, with a drip groove (9) around the mouth.

Title: Rear drive ride-on tractor unit for propelling steerable utility vehicles such as walk-behind paint stripers
Inventor: NEULING WILLIAM V
IPC: E01C23/22
Filed: 1997-02-10
Granted: 2001-10-30
Abstract: Improved paint striper control, speed and quality is achieved by articulatin g a motor driven push tractor unit (15) to a steerable walk-behind paint striping unit (40). In a preferred embodiment, a two-wheeled rear push tract or unit (50) supporting a drive motor (58) and driver's seat (26) is coupled through a quick release ball-socket pivot joint behind a three-wheeled handlebar steered push-to-paint manual striping unit (40). The articulation joint with help of a hydrostatic trans-axle transmission in the tractor unit  produces a sharp turning eighty degree radius. Also the transmission unit functions to drive the assembly in straight lines. The user controls steerin g to deviate from a straight line at the handlebar grips in substantially the same manner as if walking behind the paint striper. Thus the user rides quickly along the striping path with a good view at the paint spray jets to monitor performance and achieve higher output volume and quality.

Abstract: This infrastructure computer and program uses information supplied by sensors to calculate the operational characteristics of back up systems located at central offices during times of crisis such as the loss of commercial power, or some other natural or man-made disaster. The sensors transmit the battery float voltage, power requirements, temperature of critical telecommunication equipment components, average telecommunication equipment temperature, and the amount of fuel available for backup generators provides data to an infrastructure management computer program. The computer program accesses databases containing known information such as the power curves for the backup generators, and battery discharge curves for the battery string. The infrastructure management computer program calculates the battery hour reserve, the fuel hour reserve, and thermal reserves to more accurately predict the operational status of the central office for improved disaster planning.
