Patent CA-1079704-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE     Actuating equipment for a gate valve or penstock uses both compressed air and hydraulic oil to obtain the advantages of both.  A control valve directs air to a hydraulic reservoir so as to drive oil at the air pressure into one chamber of a double acting cylinder and piston connected to the gate.  When the gate is not being moved it is locked in position by an air operated valve preventing oil flow.  A normally energized solenoid operated control valve opens when electrical power fails so as to direct stored air from a reservoir to move the gate to a fail-safe position.     Air pipelines may provide communication over some distance from the control valves to the gate valve or penstock.  This can avoid running electric cable through a hazardous environment, while to give fail-safe operation in the event of damage to the pipelines, these are placed within a larger bore line supplying air to hold closed an air operated valve, which, in the event of loss of pressure in this line opens so that stored air moves the gate to its fail-safe position and also operates a valve preventing movement away from that position.     To apply an enhanced force to the gate for part of its travel air drives a plunger into an oil vessel in communication with the cylinder while oil cannot flow back to the reservoir.  The oil vessel and plunger are preferably housed in a single unit together with the oil reservoir, there being non-return valves between the reservoir and the vessel and between the vessel and the cylinder and an air operated valve for return flow in a conduit by-passing the non-return valves.  Air to drive the plunger can be supplied through an oscillatory valve to allow the plunger to reset and apply an enhanced force to the gate automatically as required.

Abstract: PATENT APPLICATION                           OF                NORMAN A. ROBINET                             FOR            PRIMING AND STARTING APPARATUS FOR ENGINES                 Abstract of the Disclosure Disclosed are apparatus and methods for priming and starting a two-cycle engine. A spool is drivingly coupled to the engine crankshaft. The intermediate portion of a cord is wrapped at least once about the spool leaving opposite ends of the cord free. To prime the engine, the opposite ends of the cord are grasped and alternately pulled causing rotation of the spool and crankshaft in corresponding alternate angular directions. To start the engine, one cord end is released and the opposite cord end is pulled to impart unidirectional angular rotation to the engine crankshaft and remove  the cord from the spool. In one form hereof, the spool is located in driving relation to the crankshaft between the power takeoff, i.e. a propeller, and engine. In another form, the spool is  formed as an integral portion of the propeller on the side of the propeller remote from the crankshaft.

Abstract: "IMPROVED SKID CONTROL SYSTEM"     Abstract:      A skid control system is provided for use with a vehicle having at least first and second spaced apart, independently rotatable wheels and having a braking system for applying braking forces to the wheels.  A brake control device responds to an applied skid signal for controlling the braking system to release the braking forces on the wheels.          A logic circuit provides a skid signal when the greater of an average wheel deceleration signal, representative of the average deceleration of the two wheels, and a high wheel deceleration signal, representative of the deceleration of the faster wheel, is greater than a reference.  An adaptive time delay circuit delays application of a skid signal to the brake control system for a time duration which varies in dependence upon the deceleration of the faster of the two wheels.

Abstract: ABSTRACT OF THE DISCLOSURE        The improved method of the present invention comprises cold starting a multi-cylindered diesel engine by transferring engine oil such as lubricating oil at elevated pressure from a reservoir through a conduit which extends through the air intake manifold of the engine and delivering the engine oil at elevated temperature in a uniform manner directly to each of the air intake ports of the engine cylinders until the engine starts.          The elevated pressure is preferably at least about 3,000 psi and the elevated temperature of the oil preferably occurs as the result of the transfer from the reservoir through the conduit to the air intake ports.  A temperature rise in the engine oil during this transfer is at least about 10°F. and preferably at least about 20°F.  The transfer of the engine oil is continuous until the engine starts.        The method is preferably practised utilizing the improved means of the invention.  Such means include the reservoir of engine oil, the conduit and means for continuously forcing the oil from the reservoir through the conduit at elevated pressure.          The conduit reservoir may comprise a cylinder having a slideable free-floating piston therein which during cola starting is continually forced along the length of the cylinder to continuously drive the engine oil into and through the conduit.          The method and means are simple and highly effective.

Abstract: Fluid Collector and Multipackaging System Abstract A fluid collector for collecting fluid from a drain opening such as a motor vehicle crankcase or engine oil pan and a multi-package of the fluid collector and plurality of replacement-fluid containers.  The fluid collector in a preferred embodiment com-prises a sealed container carrying a folded bag therein.  In a certain open condition of the container the bag is capable of receiving a substantial quantity of drain fluid and the container holds the open end of the bag as a funnel for receiving fluid from a drain opening.  The container is resealable for transport and disposal of the bag and container with the drained fluid therein.       In a preferred embodiment, the container is of the same size as replacement-fluid containers which are to be used to replace the drained fluid.  Thus, for example, that embodiment contemplates standard quart oil cans such as used to place oil in motor vehicle engines.  In the multipackage, an odd number of oil cans are multipackaged with the fluid collector in a rectangular array as a unitary assembly.  The invention further contemplates that the oil cans and fluid collector be multipackaged by a plastic sheet-formed strip having a plurality of container receiving apertures therein, such as is well-known for packaging beer and soft drinks in six-packs.

Abstract: TITLE OF THE INVENTION                    INDUSTRIAL TECHNIQUE     ABSTRACT     An illustrative embodiment of the invention has a group of three concentrically disposed banks of helical steam generator tubes.  Shrouds interposed between each of these three tube banks establish liquid barriers between the individual banks that prevent liquid sodium (or other shell side working fluid) from enjoying free communication throughout all of the tube banks.  In this way, potentially damaging leakage between the shell side working fluid and the water within one of the tube banks can be isolated through discontinuation of the shell side working fluid and feedwater flow to the leaking bank, thereby permitting the remaining sound tube banks to continue functioning.

Title: Pulsed radiation beam combiner or beam distributor

Abstract: A B S T R A C T           An optical commutation system for commutating pulsed radiation between a common path of relatively high pulse rate and plural, closed spaced, slowly diverging paths on which the pulses are distributed.  The system may thus act as a combiner or decombiner.  The system employs a reflective or refractive optical element which is driven to produce a very slight oscillation in the orientation of the refractive or reflective surface of the element typically ranging over only a few degrees.  The angle of oscillation is kept as small as possible, being only large enough to resolve or separate the radiation pulses on the slowly diverging paths. The very slight angular variation between adjacent ones of the diverging paths permits a large number of beams to be packed together in the bundle of diverging paths, but because of the slight angular variation, only a small angular scan resulting from the he finite pulse duration is experienced. This can be kept well within acceptable limits for use with long path lengths.
