Abstract: PENDULUM DEVICE                     ABSTRACT OF THE DISCLOSURE     In a kinetic sculpture apparatus, the lower end of a pendulum provides a scribe having a tapered tip that penetrates the surface of a bed of fine, particulate material to make an intricate pattern in the bed whose configuration is determined by the position from which the pendulum is released and the depth of penetration of the tip of the scribe.  A pair of low friction, point bearings define a primary, horizontal axis of swinging movement of the pendulum, and the intricacy of the patterns is enhanced by a resilient, upright standard that sways with the directional pull of the pendulum.  The elevation of the pendulum is controllable in order to set the depth of penetration of the scribe and thereby control the depth and width of the lines of the patterns.  In a modified embodiment, the weight of the pendulum may also be varied in accordance with the pattern configuration desired.

Abstract: ANALOG WAVEFORM TRANSDUCING CIRCUIT                  ABSTRACT OF THE DISCLOSURE        An analog waveform transducing circuit is disclosed which includes a pair of superconductive circuits connected in parallel between a pair of terminals. One of these circuits includes a Josephson tunnelling device and the other includes inductance which is greater than the inductance of the Josephson device. An analog signal is applied to one of said terminals. Means are provided for switching said Josephson device between normal and superconductive states to thereby trap one or more flux quanta. An output means is coupled to one of the two circuits.        In one embodiment the means for switching the Josephson device responds to the analog signal level only, that is the control current is fixed (or zero). In this embodiment a number of pulses may be produced which can be related to the signal level, so that the circuit is an analog to digital converter.        In another embodiment the means for switching said Josephson device includes a control means which normally results in said Josephson device being in a resistive state so that substantially all of said analog signal flows in said second circuit. When the means for switching switches the Josephson device to the superconductive state the second circuit will pass a portion of the analog signal equal to the analog signal flowing therein prior to the switching of the Josephson device. That portion of the analog signal reflecting variations in the analog signal subsequent to switching will flow in the first circuit. This condition will persist for so long as the Josephson device remains in the superconductive state. Sub-stantially all the analog signal will again flow in the second circuit after the Josephson device is again switched to the normal state by the means for switching. This embodiment performs a sample and hold function in that the analog signal level at the time of switching is maintained in the second circuit regardless of variations (within proper limits) of the analog signal level. The current flowing in the second circuit may then be measured by any utilization means to measure the analog signal level at the time of switching.

Abstract: ABSTRACT OF THE DISCLOSURE An improved tooling configuration enables production of an end panel opening score line without loss of the enamel protective coating on the reverse side of the end panel.  Current scoring methods frequently result in enamel loss, and hence, necessitate coating repair before the end panel may be attached to the can body.  By controlling the angular relationship of the score punch and anvil, while simultaneously confining the displaced metal, the enamel which was previously applied to the panel is retained substantially in place with only a slight reduction in thickness.  Punch angles of 90° - 100°  and anvil angles of 25°  - 35° have been found to be effective, with a punch angle of 90°  and an anvil angle of 30°  being optimum.          The metal may best be confined and controlled by the simultaneous formation of an anti-fracture score concentric with, and radially inward of the opening score line.

Abstract: Abstract of the disclosure A control circuit for delivering control signals to interrupt admission of the fuel-air mixture in the low speed and idle circuit of the carburettor of an internal combustion engine. The control circuit is operated according to the engine operating condition. The control signal is delivered in response to compa-rison of a signal whose level is representative of the amplitude of the variations, i.e., the absolute value of the variations in the duration of an engine cycle, with a substantially periodic signal to generate a pulse-shaped signal. The pulses have a relatively narrow width when the amplitude of the variations is great, and a larger width when the amplitude of the variations is smaller.

Abstract: PRODUCING HEAVY OIL FROM TAR SANDS        Abstract of the Disclosure A method is provided for recovering heavy oil from underground tar sand reservoir by injecting steam into an injection well penetrating the reservoir sufficiently to fracture the tar sand and provide passage for the steam through the tar sand to a production well piercing the tar sand reservoir.  Steam is provided at sufficient heat to mobilize heavy oil from the permeated tar sand and at pressure sufficient to maintain competency of the formation to permit continued flow from the injection well to the production well.  Injection of surfactant into the tar sand reservoir is used to produce a condensible foam which aids in maintaining back pressure on the injected steam within the tar sand reservoir to maintain the competency of the formation and to cause further permeation of the formation by the steam.  Foam can be produced of strength sufficient to permit pressure to be applied in the tar sand reservoir capable of further fracturing the reservoir.

Abstract: Applicant:  Maclay Morley Armstrong Title:      Extraoral Force-Applying Orthodontic Appliance ABSTRACT      An extraoral force-reaction device engage-able with the wearer's head and/or neck, such as a headcap or a neckband, is connected to an intraoral force-applying device, such as molar bands, by force-producing means, such as springs. Snapback of the force-applying means is restricted by limiting the normal range of movement of the force-applying elements and such snapback is controlled in response to relative movement of the intraoral means and the extraoral force-reaction means away from each other beyond a predetermined maximum limit, or in response to stressing of the force-producing means beyond a predetermined maximum degree of force exerted by the force-producing means. Snapback control may be effected by latching of a limit latch to prevent or limit return movement of the force-reaction device and the force-applying device, or disconnectible means can be disconnected to interrupt the application of primary fore to the intraoral means and reaction force to the head or neck engageable means. The force to be exerted by the spring force-producing means can be readily adjust-able in predetermined increments, such as by engagement of different holes in a spring anchor strap with an anchor pin, or by a linear ratchet device except where the force-producing means is of a negator type which will produce a constant force in various adjusted positions of the negator force-producing means relative to the reaction device and the force-applying device. Also, various components of the extraoral force-reaction device can be assembled and adjusted as to length by connection of separable connections, which may include linear ratchet means.

Abstract: REEL-TO-REEL WEB TRANSPORT CONTROL APPARATUS          Abstract of the Disclosure A reel-to-reel web (tape) transport apparatus which has no tape length buffering between the supply and take-up reels.  The tape follows a fixed length path from the supply reel, past a read/write head and guides, to a take-up reel.  A two motor con-trol mechanism is employed in which one motor drives the take-up reel and one motor drives the supply reel to maintain the appro-priate tension and tape motion at the read/write head.  The control mechanism is adaptive to dynamic changes as the tape is moved from the supply reel to the take-up reel.  Three quantities are monitored: lineal tape position and the angular reel displacement of the supply and take-up reel.  From these quantities reel radii are derived, tape inertia calculated and the velocity or position error is determined.   A motor current algorithm is utilized to generate the appropriate torque for each reel to drive the control error to zero along a predetermined profile with negligible tape tension disturbances.  The result is a reel-to-reel tape drive with static and dynamic performance characteristics which are independent of reel radius and inertia changes resulting from tape motion.

Abstract: ABSTRACT           A sample of an aqueous liquid, e.g. an aqueous parenterally-administered drug, is tested for determining the amount of any endo-toxin contained therein by admixing a sample of the liquid with lysate obtained by water lysing washed amebocyte cells from the blood of the horseshoe crab (Limulus polyphemus), said lysate being buffered at a pH between about 6.5 and about 6.8 and being at a concentration such that 1 ml thereof is reactive with 0.1 ml of an endotoxin solu-tion containing 1 ng per ml of endotoxin to develop upon incubation for 60 minutes at 37°C turbidity exhibiting absorbancy between about 0.07 and about 0.2 at 360 nm, incubating the resulting admixture under temperature and time conditions conducive to increase in absor-bancy resulting from reaction between said lysate and any endotoxin contained in the sample and determining the absorbancy of the resulting admixture ordinarily in relation to the absorbancy similarly obtained by reaction of the same lysate with one or more solutions of known endotoxin content, whereby the endotoxin content of the sample may be determined not only qualitatively but also quantitatively.  In ordinary practice, a buffer which provides a pH of from about 6.5 to about 6.8 when said lysate is at the aforesaid concentration is included in the quantity of lysate in a more concentrated form followed by lyophili-zation and the buffered lyophilized lysate is reconstituted with water to provide the aforesaid concentration prior to admixture of the sample with the reconstituted solution.  Improved stability of the lyophilized buffered lysate is afforded by the presence of "pipes" buffer.

Abstract: ABSTRACT OF THE DISCLOSURE    An EGR control valve is closably disposed in an EGR passageway connecting an intake passageway and an exhaust gas passageway which leads to an internal com-bustion engine.  The EGR control valve is operated to control recirculated exhaust gas flow by varying the exhaust gas pressure in a chamber between a restriction disposed in the ECR passageway and the EGR valve, in accordance with variations in a venturi vacuum in the intake passageway to prevent the recirculated exhaust gas flow from being affected by the exhaust gas pressure in the EGR passageway upstream of the chamber.  Further-more, the EGR control valve is arranged to be controlled so that the amount of the recirculated exhaust gas is reduced during high engine speed operation of the engine.
