Abstract: A portable defense device combining a flashlight with a renewable, interchangeable cylinder containing compressed gas which may be used to generate a noise, to disperse dye and/or an odoriferous spray. The compressed gas may be stored in a canister which may take the form of a spray can having the typical articulated dispensing nozzle which is then received in an articulated throat assembly displaced to release the contents by a pivoted trigger engaging a pivoted arm assembly. In the normal state the trigger is aligned over the exit opening of the throat, thus protecting the dispensing nozzle from inadvertent release, and when released the trigger aligns to engage the arm.

Abstract: Disclosed herein is a device conformed as a cylindrical structure having a bore axially bending partly therethrough, the end surface around the bore being coated with a phosphorescent coating and the bore surfaces being coated with black paint. By virtue of these coatings and the relative reflection coefficient thereof, a substantially true visual impression is created duplicating the appearance of a black hole in space. Thus the device may be used as a teaching aid assisting the user in the visualization of a complex physical phenomenon.

Abstract: Disclosed herein is a transportable cooling system for cooling drilling mud in the course of drilling for geothermal sources or deep well drilling. The cooling system includes a mud carrying radiator provided with a water sprinkler assembly and fan for cooling the exterior thereof. Both the water sprinklers and the fans are controllable in their rate in response to a signal combining the well outlet temperature. In this manner cooling demands of a well bore can be anticipated, allowing for deep well drilling.

Abstract: The present disclosure sets out an improvement in counterbalanced pumping systems of the type described in my prior application Ser. No. 824,346 filed Aug. 15, 1977 wherein two mandrels are mounted on a common shaft which also is geared through a planetary gearing system to a drive motor. The mandrels play out, in opposing directions two spirally stacked sheave chains, one going to a well bore to support the pumping assembly therein, and the other being extended into a counterbalance pit to support a counterbalancing weight at the end thereof. The stacked mandrels are enclosed in a common housing which also includes the necessary turning rollers for directing the sheave chains into the respective bores, one end of the housing being attachable directly to the exposed end of the well pipe while the other end of the housing being supported on top of the counterbalance pit liner. The housing may thus form a leak-proof enclosure in which sufficient oil may be stored to lubricate the sheave chains and the mandrels.

Abstract: Set out herein is a golf club protector conformed as an integral structure including the club tubes normally found in a golf bag, the protector or cover comprising a clam shaped upper end conformed to receive the golf club on the interior thereof. More specifically, the clam shaped cover includes a lower surface integrally attached to one end of the tube, the lower surface being in turn pivotally engaged to a mating upper surface provided with a snap lock at the free edge thereof. More specifically, the upper clam surface is pivoted from the edge of the tube, the peripheral edge thereof being formed to mate with the peripheral edge of the lower surface. Thus a hollow structure is formed which, when closed, will protect the club head from the elements and which, when opened, will permit the withdrawal of the club.

Abstract: A laser referenced control system for maintaining sequence and correcting the deflections of a moving irrigation pipe includes a laser positioned on a reference coordinate against which the irrigation program sequence and the motion of the pipe are taken. In typical use the pipe is supported on powered wheeled carriages which move across the irrigated terrain at a predetermined rate and it is these wheeled carriages that are controlled according to the deviation of the end of the pipe relative the laser optical axis. This deviation is measured in a fore and aft plane by a phototransducer array to provide the control inputs to the carriages, the vertical terrain undulations being compensated by way of a laser alignment servosystem. In this manner the vertical changes in pipe alignment are taken out, the only correction being made in the plane of translation.

Abstract: Disclosed herein is an automated system adapted to be connected to commercial film processors, the system including a common automated sequencer for advancing the wash, rinsing and fill cycles in both the developer and fixer containers. To accommodate the level requirements in the various containers and the variations in pumping rate there are periodic wait logic sections which bring the developer and fixer cycle into synchronism. The foregoing system includes an interface panel provided with level detectors and the necessary interconnections with the commercial units.

Abstract: Disclosed herein is an attachment adapted to be engaged to the power head of a chain saw, said attachment including chain reduction to drive a shaft terminating in a tapered screw. The shaft itself is provided with spline cuts along the longitudinal exterior thereof on which yet another tapered frustum is engaged. The frustum is biased away from the end screw by a return spring, the tapered screw being cut with a low pitch thread on the exterior thereof while the frustom being provided with a substantially higher pitched exterior threading. Formed adjacent the shaft is a torque reaction wedge extending proximate the tapered screw, the wedge being insertable into the split formed by the screw to oppose any torsion generated thereby.

Abstract: The present disclosure entails a program controlled multi-loop system for providing even distribution of irrigating water over normally square plots. More specifically the disclosure includes control loops connected to a center post irrigation system which control the advance rate, the flow rate, select an end gun nozzle, and select the elevation of the end gun under program control to provide even coverage. In this manner a telescopically extended system of the type described in our prior U.S. Pat. No. 4,033,508 is improved to both insure even irrigation and full coverage of corners.

Abstract: A blocking oscillator DC to DC converter includes a first transformer which is charged up and provides feedback to a switching transistor on one half of the cycle and discharges stored energy from the secondary during the second half of the cycle. To reduce switching losses the first transformer driven switching transistor is turned off by a control transistor disposed between the switching transistor base and ground, the control transistor being turned on and off according to the charge on a base capacitor charged by the first transformer. A second transformer may be included to control the power across a gap disposed to kill flying insects.

Abstract: An eccentric balancing system for assisting the reciprocal motion of a well pump which includes a first mandrel having wound thereabout a first sheave chain, the wind up of the first sheave chain being arranged for stacked alignment. A second mandrel, mounted for rotation with the first mandrel, is wound in the opposite direction to store in stacked arrangement a second sheave chain which may be either connected to a counter balancing weight or which may be deployed to articulate a second well pump. In the event that the second mandrel is utilized to articulate a second well pump a third mandrel may be utilized for counterbalancing any inequalities between the two well bores. It is intended to include a switching circuit, which according to the playout of the sheave chains engages an electric motor to augment the losses attendant with pumping fluid and the friction losses in each bore.

Each disc is mounted for rotation on a corresponding pin, the pins being received in cam grooves formed in the driving plate in a first embodiment and being mounted for eccentric rotation in the second embodiment. A centrifugal bob weight attached to each pin in the second embodiment controls the eccentric alignment of the pin thus controlling the displacement of the disc relative the first and second set of dished washers.

Abstract: A weaning device comprising a rubber nipple having the opening thereof conformed for receipt of a drinking straw, the other end of the straw being insertable into a liquid container. In this form as an infant becomes adept in ingesting larger volumes of liquid through a nipple the foregoing device may be substituted therefor comprising one step of a weaning process whereby the child is taught to ingest liquids through a straw.

Abstract: A motion detector comprising a self-excited oscillator operating in the megacycle range which is maintained at a substantially fixed frequency by way of a constant current source. By virtue of the constant current input changes in inductance and capacitance associated with the motion of the intruder are registered as changes in oscillatory amplitude rather than frequency change. This change in amplitude is passed through a low band pass filter, i.e. a filter operating in the range of frequencies normally associated with the motion of a human, and the changes in this filtered signal are then passed through a coupling capacitor to a comparator. In this manner, the DC level, which often drifts in a linear circuit is taken out. The output of the comparator is then applied to a coded transmitter which on the occurrence of an intrusion will set off an alarm at a remotely held receiver.

Two peripheral frame members conforming to the halves of the peripheral edge of the base are hinged in diametric alignment on the base, the free edges thereof being engaged to corresponding connecting members which at the other end attach to a collar disposed around a tubular guide telescopically attached to extend out of the free end of the mount. Disposed on the interior of the guide is a latching rod including a lip on the lower end thereof engageable by said latch, the rod engaging the collar through two longitudinal slots formed in the guide.

Abstract: Apparatus for splitting logs adapted for use with a power head of a chain saw comprising a screw jack mounted for rotation on the interior of a support channel, the input end of the screw jack being connected through a plurality of reduction gears to a drive sprocket. The screw jack itself is in turn threadably engaged to a travelling axe head conformed for sliding translation within the support channel. A part of the axe head is shaped as a wedge projecting beyond the confines of the channel to advance therealong towards a V-shaped stop bracket. An eliptical cam is mounted for rotation in the thick end of the wedge to be articulated from its narrow alignment to a broad alignment by an articulating lever disposed to advance against one of the legs of the V-shaped stop bracket. As the eliptical cam is thus rotated, expanding the lateral dimension of the axe, separation of the split is achieved.
