Patent CA-1322665-C (CA)
Title: Polymethylene urea fertilizer solution
Inventor: MOORE WILLIAM P
IPC: C05C9/02
Filed: 1988-09-19
Granted: 1993-10-05
Abstract: ABSTRACT OF THE INVENTION        A two stage method for preparing clear, storage stable, controlled release polymethylene urea nitrogen fer-tilizer solution.  In the first stage, urea is reacted with a molar excess of formaldehyde, with temperatures of 75 to 100°C, at near-neutral pHs provided by buffers such as so-dium bicarbonate, in the presence of ammonium compounds, until the formaldehyde is substantially converted to methy-lene moieties.  In the second stage, the methylene moieties are reacted with additional urea and ammonium compounds, with temperatures of 75 to 100°C, in a near-neutral buffered solution at a pH of between 6.9 and 8.5, until the added urea is substantially converted to water-soluble branched chain polymethylene ureas.  Optimum urea to formaldehyde mol ratio in the first stage is between 0.483 and 0.518 to 1 and in the second stage optimum ratio is between 1.3 and 1.5 mols urea per mol of formaldehyde.  The polymethylene ureas comprise a number of water-soluble chemical compounds con-taining 2 to 4 methylene moieties, 2 to 5 urea moieties, and 0 to 2 ammonia moieties including the different structural isomers for several of the same empirical formulae.  The product formed by the two stage process contains little methylolurea and methylene diurea which are associated with reduced storage stability.  Because of the two step process which provides low urea, ammonia and methylolurea concentra-tions, the product exhibits controlled nitrogen nutrient release to plants.

Title: Cellular radiotelephone system with dropped call protection
Inventor: SPEAR STEPHEN L
IPC: H04W36/38
Filed: 1988-10-28
Granted: 1991-02-19
Abstract: Abstract An improved cellular telephone communication system is described having operational steps which prevent a call from being dropped due to a radiotelephone not receiving a handoff instruction from its host base site. The system includes a switch controller for determining that the radiotelephone requires a handoff from a first base site coverage area to a second base site coverage area and for communicating a handoff message to the associated first and second base site equipment.  The first base site equipment then transmits the handoff message to the radiotelephone.  If the radiotelephone does not receive the message, it determines that the call has been lost, siezes a signalling channel from the second base site, and requests, via the second base site a call reconnection by transmitting a special message. The second base site then informs the radiotelephone of the handoff instruction and the handoff is completed with a successful reconnection of the call.

Title: Agricultural bale sheathing apparatus and method
Inventor: STIRLING WILLIAM
IPC: A01F25/14
Filed: 1989-01-19
Granted: 1992-06-09
Abstract: Abstract of the Disclosure A bale sheathing device for loading bales of an agricultural product, e.g. silage, into an elongated, flexible bag, comprises a framework movable along the ground and supporting an open-ended drum that has an outer surface for supporting the bag in a compressed condition. The device has pads connected to the framework that can be lowered to a location underlying the wheels of a vehicle that is used to load a bale through the drum and into a space in the bag beyond the drum.  The result is to immobilize the device during the loading operation by virtue of the weight of the vehicle on the pads.  The same vehicle can be used between bale loading operations to pull the sheathing device forwards to a new location to dispense a portion of the bag from the surface of the drum and hence create a space in the bag to receive the next bale.
