Abstract: There is disclosed a method for detecting clogging of air feed pipes, comprising air feed pipes (15), each having an outlet (13) for jetting air into a granulation section (1), and jetting nozzles (13), each situated at the center of the air outlet of a said air feed pipe for jetting a liquid of a molten raw material (e.g. molten urea), wherein, in jetting the liquid of the molten raw material from the jetting nozzles into the granulation section to carry out granulation, (a) an orifice section (14) is provided at a lower part of each of the air feed pipes (15), a section for taking up orifice rear pressure (16) is provided in each air feed pipe and is located downstream of the orifice section, and a section for taking up orifice forward pressure (17) is provided upstream of the orifice section, and (b) the pressure difference between the orifice forward pressure and the orifice rear pressure is measured, to detect clogging of the air feed pipes based on an abnormality in the pressure difference regarding the air feed pipes. There is also disclosed a granulation method, comprising monitoring the pressure difference by the above method, stopping the feed of a liquid of a molten raw material to the air feed pipe whose pressure difference is abnormal, and compensating the amount corresponding to the stoppage with the remaining function.      The detection method is a method capable of detecting accurately a malfunction related to jetting of air in the granulation of urea or the like. Further, the granulation method is a granulation method wherein, accurately, in response to the occurrence of a malfunction related to the jetting of air, the feed of a raw material liquid to the malfunctioned section is stopped, and the raw material liquid to be fed to the jet nozzles having other normal air outlets is suitably increased, thereby allowing continuous operation, with the productivity before the occurrence of the malfunction kept.

Abstract: A disposable oxygenating device is described for passively providing oxygen to a breathing patient. The device comprises a body and a collapsible bag coupled thereto, the body including first coupling means being couplable to a source of oxygen.  A second coupling means is couplable to an endotracheal tube, laryngeal mask or similar device. A connector is connected to the bag and an oxygen duct is in fluid communication with the first coupling means, having an outlet orifice which in use delivers oxygen from the source of oxygen to inflate the bag with oxygen, and an outlet. The arrangement is such that, in use, the oxygen causes inflation of the bag, and, during an inspiration cycle, oxygen from the bag passes through the second coupling means causing the bag to collapse or partly collapse and, during the expiration cycle, expiration products pass through the body and are expelled through the outlet.

Abstract: A method for recovering viscous oil from a subterranean formation through a wellbore having a horizontal section into the formation. Steam is circulated through the horizontal section to initially heat the formation and to produce fluids to the surface.      After the initial heating is complete, production is ceased while the injection of steam is continued to accumulate a slug of steam within and around the horizontal section. The well is then shut-in and the formation is allowed to "soak". Production is then resumed and steam is again continuously injected into the well when oil appears in the produced fluids. This cycle is repeated until the production of oil drops belows an acceptable rate.

Abstract: A system of reciprocating bottom hole sucker rod pumps, situated in an oil well, to produce an oil rich stream to surface and inject a water stream to a same wellbore disposal zone. Two pumps vertically in tandem are actuated by a single sucker rod string. Separate intakes for each pump are situated so as to allow for gravity to segregate oil and water in the wellbore before reaching the intakes. Both streams are produced out of the pumps on the upstroke. Injection of the water stream is facilitated by an outer housing around the bottom pump to redirect flow to a disposal zone.

Abstract: A vehicle speed control system includes a high speed/low speed selection switch and a speed control relay connected to a voltage source through a switched power line. The speed selection switch includes an input connected to the power line through the speed control relay. One output on the speed control switch is connected to an electrohydraulic valve which controls the speed range on a vehicle. The state of the electrohydraulic valve is dependent both on the switch position and on the state of the relay. The relay is deactivated when the power line is switched off and changes back to an activated state to allow high speed operation only if the speed selection switch is first placed in the low speed position after the vehicle power line is switched on. If the selection switch is in the high speed position when the power line is on, the speed control relay will remain inactivated until the selection switch is moved to the low speed position. Thereafter, movement of the selection switch to the high speed position with the switched power line on and the speed control relay activated activates the electrohydraulic valve to place the vehicle in the high speed condition. The operator therefore must change a switch position before high speed operation after start up, regardless of the position of the speed selection switch on start up. A similar circuit utilizing a three position switch provides hydraulic system flow control with high flow inhibited until the operator manually changes the position of the switch.
