Patent CA-2013307-A1 (CA)
Inventor: CARLSEN ARNE
IPC: C06B47/14
Filed: 1990-03-29
Abstract: Abstract The present invention relates to a HANFO explosive consisting of a mixture of at least one nitrate-oil explosive (ANFO-type) and at least one water-in-oil explosive, and a method for its manufacture.  The oil of the ANFO part contains 0.3 - 7.0 weight% based on the weight of the oil component of the oilsoluble elastomer having a viscosity average molecular weight of 30.000 - 5 mill., preferably 900.000 - 2.5 mill. The manufacture of the HANFO explosive can be carried out by first adding an oilsoluble elastomer to the oil of the ANFO-type explosive, then mixing the oil with sodium-, ammonium- and/or calcium nitrate and then mixing this mixture together with a water-in-oil emulsion explosive. The HANFO explosive can be applied both in bulk and cartridged form.
Patent CA-2015352-A1 (CA)
Inventor: BARBER DENNIS R
IPC: A01B63/22
Filed: 1990-04-25
Abstract: A hydraulic control system is provided which includes a pair of transversely spaced rockshaft cylinders which are plumbed in parallel and connected to opposite ends of a rockshaft on the central portion or main frame of a wide implement such as a field cultivator or chisel plow.  The left-hand rockshaft cylinder is connected in series with a right-hand outer cylinder located near the right end of the implement.  The right-hand rockshaft cylinder is connected in series with a left-hand outer cylinder on the opposite side of the implement.  When a ground condition exists which causes, for example, the left side of the implement to dig more deeply and the left-hand wing cylinder to retract, the right-hand rockshaft cylinder will also be caused to retract so the right side of the implement tends to dig in more deeply.  At the same time because of the parallel connection of the rockshaft cylinders, the left-hand rockshaft cylinder will be forced to extend to reduce the depth of penetration of the left side of the implement which offsets the tendency of the left side to dig in and provides a more uniform average working depth across the width of the implement.
