Abstract: An oxygen sensor testing device having an oxygen sensor disposed in a rear stage of a synthetic gas passage to evaluate the oxygen sensor using a synthetic gas supplied to the synthetic gas passage, in which a sulfur dioxide gas passage supplied with sulfur dioxide gas communicates with a front stage of the synthetic gas passage to supply sulfur dioxide gas to the synthetic gas passage, thereby enabling exact evaluation of the oxygen sensor using the synthetic gas having composition close to actual exhaust gas containing sulfur dioxide.

Abstract: A method of automatically assembling egg rolls, or comestibles formed into an elongate cylindrical mass, employs a wrapping leaf that is elliptical in planform and has a minor axis of length not more than twice the axial length of the cylindrical mass plus twice the diameter thereof, the major axis of the ellipse being appreciatably longer than said minor axis, the grain of the wrapping leaf and the direction of rolling each extending in the direction of the major axis.

Abstract: An applicator for a condom includes an axial wall of accordion pleated buttressed tooth form which is extendable from a collapsed condition to an extended position and will resist collapsing thereof towards the retracted position, and a condom is contained within the applicator in hermetically sealed relation therewith, such that the condom is expanded upon axial extension of the applicator.

Abstract: An automatic device for producing ice cubes has separate probes for measuring the temperature of the environment, and, for measuring the temperature of water supplied to an input of the device, the probes being connected to a monitoring device operative to calculate the optimum operation of the device under any particular climatic conditions.

Abstract: Three dimensional mapping and modelling apparatus comprising apparatus for providing coordinate information with respect to a three-dimensional element, workstation apparatus arranged to receive the coordinate information from the providing apparatus and to permit manipulation of the coordinate information, and apparatus responsive to manipulated coordinate information for automatically providing a three-dimensional model of a desired three-dimensional element.

Abstract: A mixture of the synthetic peptide compounds of the formulas:Formula (I) Tyr-Gly-Gly-Pro-Ala-Asn-Lys-Lys-Asn-Ala-Gly-OH,Formula (II) Asp-Glu-Leu-Glu-Ala-Glu-Thr-Gln-Asn-Val-Tyr-Ala-Ala-NH.sub.2, andFormula (III) Tyr-Ser-Leu-Phe-Gln-Lys-Glu-Lys-Met-Val-Leu-NH.sub.2,and compositions thereof, induces antibodies against the late stages of Plasmodium faciparum malaria and provides protection against infection with this parasite, thus providing a synthetic malaria vaccine for Plasmodium falciparum induced malaria.A synthetic protein copolymer vaccine, polymerized from a monomer which is a hybrid of formulas (II), (III) and (I), and which also includes the (Asn-Ala-Asn-Pro) sequence of the CS protein between formulas (II) and (III) and Formulas (III) and (I) of the monomer, has been shown to provide safe and complete self-limiting protection in human volunteers against the asexual blood stages of P. faciparum induced malaria.

Abstract: A wheel presetting apparatus has a pair of rotatable lower rollers and a pair of rotatable upper rollers mounted above the lower rollers and movable into contact with a wheel supported on the lower rollers. A center pin is supported for forward and backward movement in relation to a center hole of the wheel, and, a bolt hole detecting means is provided for detecting the angular position of a bolt hole of the wheel. A hub pin is supported for forward and backward movement, and is inserted into a bolt hole which is out of the phase of the bolt holes detected by the bolt hole detecting means.

Abstract: A process is disclosed for the manufacture of aluminium-graphite particulate composite using uncoated graphite particles for automobile and engineering applications. In the process the aluminium-alloy melt is treated with a reactive metal to increase the wettability of the alloy and the graphite particles. Further treatment of the melt and gradual addition of activated graphite powder and stirring at about 500 to about 600 r.p.m. at a temperature of about 700.degree. to about 720.degree. C. result in the composite.

Abstract: A mold mounting apparatus having a mold holding apparatus provided on one side at the end of rails, for positioning and holding a mold; a second mold holding apparatus provided on the opposite side of clamping machines of an injection molding machine and the rails, for preheating, positioning and holding the mold in place; a mold delivery apparatus for delivering the mold to two clamping machines; and a mold carrying apparatus for receiving and delivering the mold among the mold holding apparatus, the second mold holding apparatus, and the mold delivery apparatus, and for conveying the mold along the rails. According to this mold mounting apparatus, the mold can be automatically carried into, and out of, all of the clamping machines after the mold has been brought into the mold holding apparatus, thereby improving mold changing operation efficiency and saving a space for the molding process.

Abstract: This invention relates to an air treating device. Two halves of a hollow ball are connected. A rotatable ring is provided which has an aperture which in one position is sealed and in another open to release volatilizable material. The halves may be connected by a post upon which a donut shaped disc of fragrant material can be mounted.

Abstract: For the purpose of detection of a zero-cross point of an input signal, the input is applied to one of two input terminals of a comparator which has an inverted input terminal and a non-inverted input terminal, the same bias voltage is applied to each of two input terminals of the comparator from a bias voltage supplying circuit, the value of the bias voltage applied to either the inverted input terminal or the non-inverted input terminal of the comparator is changed by a bias voltage changing circuit from that determined by the bias voltage supplying circuit depending on whether the output of the comparator is in its high or low level, the output of the comparator is a detection signal of the zero-cross point of the input signal.

Abstract: An automatic wheel mounting apparatus provided with a robot for positioning a wheel on a hub of an automobile and for tightening nuts onto hub studs, which has a lifting device for lifting the hub in a direction to cancel the camber angle, a head positioned by the robot, and a measurement and positioning unit disposed on the head and having a hub center measuring device, a hub stud positioning device, and a hub inclination measuring device, whereby an inclination condition of the hub surface due to steering angle or the like is detected by the hub inclination measuring device to cause the measurement and positioning unit to confront the hub, the hub center is measured by the hub center measuring device to align the center of the measurement and positioning unit with the hub center, and then the hub is rotated by the hub stud positioning device to position the hub studs at predetermined positions.
