Abstract: Young animals, ruminant or otherwise, which employ monogastric digestion, e.g. calves, are fed a milk substitute prepared with soybean protein which has been heated in presence of a lower alcohol and water, with unexpectedly rapid increase in animal weight.

Abstract: A compact golf course of a type designed, as much as possible, to simulate all of the features of a full size golf course. The golf course has a set of playing areas surrounding a set of elongated target fairway areas. The number of target fairway areas is substantially less than the desired number of holes and the number of ball hitting areas is substantially greater than the number of target fairway areas. There are a number of target green areas adjacent the target fairway areas which are all identical to each other and are spaced at uniform distances from the ball playing areas. Certain of the ball hitting areas simulate tee or fairway areas and others simulate rough portions of a golf course. The target fairway areas are disposed at an angle with respect to each other. Adjacent each tee area is a sign indicating the total distance for that particular hole and the nature of the approach to the hole.

Abstract: A soil supplement for addition to potted plants consisting of microorganisms, enzymes, and various substances rich in protein and carbohydrates including bone meal, torula yeast, potassium citrate, soybean flour and durum wheat flour. The potassium citrate acts as a chelating or sequestering agent. The substance is used in connection with the water used to moisten the soil of the potted plant. The effect of adding the supplement to the soil is that the microorganism count greatly increases due to the microorganisms and enzymes acting on the various substances rich in protein and carbohydrates. The sequestering agent tends to maintain the solution in suspension through the earth. As water and/or the supplement are added to the soil from time to time, any salts accumulated on the surface of the soil or on the edge of the pot are gradually sequestered into the soil and are ionized by the action of the enzymes and microorganisms to produce minerals useful for the plant.

Abstract: A revolving hanger for a planter in which a motor is employed to revolve the hanger support. This motor is preferably a weight operated motor with suspended weights which are located in the area normally occupied by the cords supporting the planter so that the weights are relatively unobtrusive. Because of the use of a weight wound motor, it is possible for the user to readily wind the motor while standing on the floor by moving the weight to the desired elevated position for initiation of the rotation of the planter.

Abstract: An aerator in which air is forced into the liquid by means of a helical rib surrounding a cylindrical member which is rotated in such a direction that air trapped beneath the helical rib is forced downwardly into the liquid. A diffuser at the bottom of the helical rib is effective to break up the trapped air bubbles into finer bubbles which are dispersed through and retained by the liquid. The cylindrical member on which the helical rib is disposed may be rotated by an electric motor which may be disposed either above the water line or beneath the water line at the bottom of the helical rib. Where necessary, air may be pumped into the space above the water so as to facilitate the introduction of air about the helical rib. Where the aerator is to be used with a container of limited size, the aerator may be either mounted on the cover of the container or may have associated therewith a closure member adapted to fit into the neck of such a container.

Abstract: An implantable unit for stimulating an internal body organ in which there is a power supply portion for having power induced therein from a source external of the body and electrodes adapted to be attached to a muscular organ such as a bladder or the like, said unit having an energy storage device, such as a capacitor, connected to the electrodes under the control of a transistor which is normally maintained non-conductive as a result of the voltage drop across an impedance connected to the power supply so that each time that the power supply is interrupted, the transistor becomes conductive to discharge the energy storage device through the electrodes and apply a stimulating voltage to the organ. The transmitter source external of the body is designed to periodically interrupt for a short period the voltage transmitted thereby so that the voltage produced by the power supply of the implantable unit is thus periodically interrupted.

Abstract: Electronic fence surveillance apparatus in which a plurality of sections of relatively rigid electrical conduit are supported by the fence serially therealong and independently of the fence posts, the sections being connected by a plurality of liquid tight housings each interposed between and having a threaded liquid tight connection with the adjacent sections of conduit and in which there is a vibration sensor secured in each of the housings and responsive to vibrations transmitted to the housing in which it is located, each of the vibration sensors being effective to produce a vibratory electrical signal upon the conduit being vibrated and transmitting this signal to an indicating device through an electronic network. The vibration sensor is in the form of a piezoelectric element designed to operate within the range of frequencies occurring in the conduit when the fence is disturbed. The conduit is preferably of iron or steel and has a wall thickness of between 0.10 and 0.

Abstract: An articulated tractor in which there is a front first tractor vehicle and rear second and third tractor vehicles, each of the tractors having an engine for driving the wheels of the tractor and the first tractor having an operator's compartment, the second and third tractors being connected to the first tractor through a cross bar pivotally secured adjacent its longitudinal midpoint to the rear of the first tractor for pivotal movement both about a generally vertical axis and a generally horizontal axis. The rear second and third tractors are secured to the cross bar by pivotal connections at points equally spaced from the first pivotal means so that the longitudinal axis of the second and third tractors are normally substantially parallel to each other.

Abstract: An action toy having a platform with a resilient sheet member providing a playing surface of the upper side, the sheet member being supported so as to leave a space beneath it, and a manually operated, elongated leaf spring mounted so as to extend partially beyond the platform and partially within the platform underneath the sheet member in such a position as to intermittently engage the under side of the sheet member when the resilient strip is vibrated. The strip is mounted in the platform in such a manner that when the outer portion is vibrated by engaging and then suddenly releasing the outer end, the vibration is transmitted to the inner portion to cause the inner end to intermittently engage the under side of the sheet member. The playing pieces placed on the playing surface are designed for movement therealong when the playing surface is vibrated. For example, the playing pieces may have resilient feet inclined upwardly in the direction of the desired movement.

Abstract: A throttle control system for a tractor having at least three tractor vehicles each of which has its own engine and wheels driven by the engine, in which there is means responsive to change in angular relationship of the vehicles to change the relative settings of the throttles of the vehicles in the rear so that the engine of the vehicle on the inside of the turn tends to operate at a slower speed than the engine of the vehicle on the outside of the turn. There are cables running from a throttle control in the operator's compartment of the lead vehicle to the throttles of all three vehicles, the angle responsive means being effective, when the throttles are in advanced position, to override the action of the main throttle lever and move one of the throttles towards throttle retard position without disturbing the position of the main throttle control.

Abstract: A bland, nutritive, water-retentive soybean flour, concentrate, or other food product is produced by a process involving heating soybean material under superatmospheric pressure and in contact with alcohol and water and/or their vapors while permitting continuous escape of vapors.

Abstract: A three-way valve in which the valve disc is in the form of a flexible disc having a diameter slightly in excess of the interior diameter of the valve port so that as the valve is moved between its two valving positions, the valve disc is "flipped" over center so that its outer edge is always deflected towards the incoming fluid. In this way, the pressure drop through the valve tends to hold the edge of the disc firmly against the interior wall of the chamber. The valve disc is held between two collars retained on the valve stem which serve to maintain the central portion of the valve disc rigid. The valve stem may be actuated by a solenoid or any other suitable means.

Abstract: Apparatus for measuring the ignition timing of an internal combustion engine of the type having a pulse generator for indicating when the flywheel is in a predetermined position subsequent to top dead center and in which a pulse of predetermined amplitude is initiated by a signal from one spark plug and is terminated by a signal derived from the pulse generator. Correction is made for the reference angle between the top dead center position of the piston and the occurrence of the signal from the pulse generator by algebraically adding to the pulses a DC correction which is adjusted to conform with the known reference angle. The adjusted pulses are applied to a meter to indicate the amount of ignition advance or retard. A second meter indicates the amount of the correction voltage. The apparatus also has novel calibrating means for applying to the timing device two spaced voltage pulses spaced apart by the distance of a half cycle of a periodically varying commercial voltage of known frequency.

Abstract: A tractor having a driver's cab, an accessory compartment in the fender immediately adjacent the door to the driver's cab, the accessory compartment having a cover forming part of the fender and which projects below the edge of the cab door so that when the cab door is closed, it is impossible to raise the cover of the accessory compartment. In this way, when the door is locked, the accessory compartment is also automatically locked. The accessory compartment may hold a battery or tools or both. In the particular form shown, there is a battery compartment and tool compartments adjacent to the battery compartment. The invention is particularly applicable to the type of tractor which is sufficiently large that steps are required to reach the door of the driver's cab. In such case, the cover for the compartment may also include a downwardly extending part of the fender and one of the steps may be secured to this downwardly extending part.

Abstract: A yieldable door latch for holding open the door of a tractor cab in which the fender adjacent the door is of a width comparable to the width of the door, the door latch being mounted adjacent the outer edge of the fender so as to engage the under side of the door at a point close to the outer edge of the door. The door latch has biasing means located beneath the fender for biasing the door latch upwardly and has two inclined surfaces inclined upwardly from the outer and inner ends of the latching member to a central notch which is designed to receive the lower edge of the door. This biasing means is located beneath the fender and has an adjustable stop for limiting the upward movement of the latching member so that the outer end of the latching member always lies beneath the path of the lower edge of the door.

Abstract: Air conditioning apparatus for a tractor cab in which filter and air inlets are disposed in a portion of the roof projecting rearwardly beyond the cab, the air inlet being downwardly disposed so that foreign matter accumulating in the exterior of the filter is free to fall off of the filter and out through the air inlet. The heat exchange means for removing heat from the air is located behind and beneath the cab seat with the air outlet opening into the cab so as to direct cool air into the cab behind and beneath the operator. The cab may have one or more rear corner posts which are hollow and the air passing through the filter is passed through at least one of these hollow corner posts to the heat exchange means. The filter preferably extends transversely with respect to the cab. Two filters may be employed, these filters being spaced apart with a booster fan located between the filters and directing air passing through the filters downwardly to the heat exchange device.

Abstract: Apparatus for measuring the ignition timing of a multi-cylinder internal combustion engine of the type having a pulse generator for indicating when the flywheel is in a predetermined position with respect to top dead center and in which an input signal is obtained from one particular spark plug and employed to initiate a counting operation employing a series of pulses which have a definite frequency relationship to the speed of the engine. The counting operation is started at the time that the pulse from the selected plug is received and is terminated when the reference signal is received from the pulse generator. Provision is made for compensating for different reference angles between the top dead center position and the position at which the pulse generator produces a pulse. This is done by presetting a counter in accordance with the reference angle.The apparatus can also be used as a tachometer.

Abstract: An adjustable recliner chair of the type in which the chair back is pivoted at an intermediate point to a supporting frame and the chair seat is pivotally supported at its rear by the chair back so that as the chair back is tilted rearwardly, the chair seat moves forwardly, the chair seat having adjacent its front an inclined cam surface which slidably engages a support member secured to said supporting frame so that as the chair seat moves forwardly the front of it moves upwardly. The support member and inclined cam surface are held together by an adjustable friction connection which is adjusted to vary the frictional effect tending to hold the chair seat in any adjusted position. The supporting frame may be mounted on a base through coil springs which enable the chair to be rocked.
