Title: Method and apparatus for applying edge protectors
Inventor: KASEL CALVIN E
IPC: B65B13/18
Filed: 1996-03-19
Granted: 2000-02-22
Abstract: A strapping system in which edge protectors are disposed between a load and tensioned strapping applied about the load in a strapping station. Edge protector applicator assemblies located on opposing sides of the load position edge protectors adjacent a top and bottom surface edge portion of the load when the load is raised above a deck.  The edge protectors are folded over and retained on edges of the load upon application of the tensioned strapping about the load to protect the edges of the load from the tensioned strapping. The strapping system includes a movable frame with spaced support members disposed below the deck and aligned with spaces in the deck. The frame is raised and lowered so that the support members of the frame extend through the spaces of the deck to lift the load above the deck to allow positioning of the lower edge protectors adjacent to the load. The frame is guided as it is raised and lowered by rotatable shafts aligned substantially parallel with corresponding side portions of the frame. Each shaft includes a miter gear disposed on its end portions for engagement with a miter gear of an adjacent shaft to permit synchronized rotation of the shafts. A pinion gear rotatable with the shaft and engagable with a rack on an adjacent side portion of the frame guide the frame as it is raised and lowered.

Patent CA-2184044-C (CA)
Inventor: BRANCONNIER RENE JOSEPH
IPC: C05F17/00
Filed: 1996-08-23
Granted: 2001-03-27
Abstract: A thermophilic, aerobic fermentation process is disclosed for conversion of a wide variety of organic waste materials to useful end products. The fermentation process is initiated over a period of from about 2 to 6 days by application of external heat to an uninoculated, oxygenated aqueous mixture of the waste material, and thus utilizes thermophilic microorganisms naturally present in the waste material to initiate the fermentation. After initiation of an active fermentation, additional amounts of waste material are added to the fermenting mixture on a continuous or intermittent basis to maintain the fermentation in an active state. Therefore, the process can be conducted on a continuous or semi-continuous basis, requiring about 24 to 48 hours for waste to be completely converted to end product. The process is capable of being operated over a wide pH range and can ferment acidic waste materials without the need for pH adjustment. The process converts waste matter such as food waste and fecal matter into a protein enriched end product suitable for use as an animal feed, feed supplement or fertilizer, fertilizer ingredient, soil amendment or soil conditioner free of pathogens, biological contaminants and chemical contaminants such as antibiotics.

Title: Mobile automated pipeline welding and quality control system
Inventor: MARHOFER WILLIAM E
IPC: B23K9/12
Filed: 1997-03-13
Granted: 2007-06-05
Abstract: A mobile automated pipeline welding and quality control system comprising a gas metal arc welding carriage and a weld data monitor and acquisition unit. The welding carriage carries a welding torch, wire feed device for feeding consumable wire to the torch, an oscillator for oscillating the torch and a motorized drive mechanism for moving the carriage about a weldment. A controller for the carriage includes digital control circuitry for dosed loop control of the drive, oscillator and wire feed devices. By default, the controller operates each device at one of a plurality of pre-programmed nominal speeds selected from a mode table. The controller is responsive to drive, oscillation and wire feed speed variation signals under the control of an operator, and varies the speed of each device within speed ranges which are selected to ensure compliance with welding specifications. The monitor has voltage and current transducers for measuring current and voltage at the welding torch. The controller supplies the monitor with speed data relating to the drive, oscillator and wire feed devices. All of this information can be displayed and recorded in the monitor's memory. In addition, the monitor can compute and display the heat input into the weld based on the detected welding parameters. This information allows the operator to make minute adjustments during the welding process to ensure that a weld falls within specifications.

Title: Methods and apparatus for initiating wireless messages
Inventor: ROCHKIND MARK MEIER
IPC: H04W4/02
Filed: 1997-07-02
Granted: 2002-04-16
Abstract: A communications system allows special messages to be transmitted to a wireless device subscriber if certain conditions are met. Identification information authenticating the sender may be sent using an originating device, such as a personal computer with a modem. A location information generating device, such as the ANI generator in a telephone end-office connected by physical telephone wire (local loop) to the computer, generates location information. The identification information and location information are provided to a message platform. The message-platform establishes time of day and compares sender identification information, originating device location information, and time of day information to prestored values to determine whether a special prestored message should be sent. If a message should be sent, the message platform initiates message transmission. Message transmission can be initiated if appropriate sender identification and location information are not received within a specified time window. The personal identification information, location information, and time of day information are furnished by three different devices operating independently of each other.

Title: Device for the controlled spraying of pulverulent lubricants onto punches and dies of tableting presses
Inventor: MAASZ JOACHIM
IPC: B05B14/10
Filed: 1997-11-10
Granted: 2007-01-09
Abstract: The device for spraying a pulverulent lubricant or release agent dispersed in an air stream onto the pressing tools in a tableting press, comprises at least one spray nozzle 14 for applying the powder-containing air stream to the pressing tools, a suction system 16, 19, 20 for sucking the excess residues of lubricant off the pressing tools and a metering device 1, 2, 3, 4, 5, 6 having an air jet injector 3 for reproducibly loading the air stream with the lubricant. The essential step consists in the fact that the pressing tools 15a, 15b of the tableting press are connected to a sensor 21, which generates an output signal which is characteristic of the extent to which the lubricant is covering the surfaces of the pressing tools and controls the amount of air sucked off at the suction system 16, 19, 20 and/or the loading of the air stream with the powder. As a result it is possible to achieve a reliable and operationally safe lubrication of the punch surfaces in the tableting machine even when tableting critical products which tend to cake. Moreover, the operational reliability and the service life of the machine are improved.
