Abstract: Test apparatus for the oil cooler from a Volkswagen.RTM. automobile including a support having apertures and studs compatible with the mounting studs and apertures of a Volkswagen.RTM. oil cooler. The support has an air chamber with two ports communicating with the ambient atmosphere located to sealingly engage with the inlet and outlet ports of a Volkswagen.RTM. oil cooler when the oil cooler is mounted on the support. A pressure gauge is connected to the air chamber, and a one-way air entry conduit is also connected to the air chamber. When the oil cooler is installed on the support air under pressure is applied to the air entry conduit which fills the air chamber together with the oil cooler. When the pressure remains constant it indicates that there is no leak in the oil cooler. Conversely, a pressure drop indicates a leak in the oil cooler.

Abstract: Device for measuring the volume of sections of a tubular blank by ultrasonic echography. An ultrasonic pulse emitter -receiver is associated with an auxiliary reflector. The transducer and the auxiliary reflector are mounted on a rotary head. The blank moves forward continuously and the ultrasonic beam describes a helix on its surface. On basis of the measurement of the distances from the transducer to the outer and inner surfaces of the tube, a computer calculates the elementary areas and volumes and compares the sum of the elementary volumes with a reference value. The sections of constant weight are marked by a component controlled by the computer.

Abstract: The disclosed apparatus is presented, for ease of comprehension, in terms of apparatus for servicing refrigeration systems, the disclosed apparatus using readily obtainable temperatures, rather than using the prior-art method of breaking into a refrigeration line for the purpose of measuring pressures.An added feature is the ability of the apparatus to provide either absolute temperature read-outs for the temperature at the desired locations, or a differential temperature read-out for the temperatures between two desired locations. Moreover, the disclosed apparatus permits vacuum read-outs and pressure read-outs, again without the necessity of breaking into the refrigeration lines.Since various refrigeration systems use different refrigerants, the disclosed apparatus also has the ability to convert the temperature read-outs to pressure read-outs that are associated with specific refrigerants.

Abstract: Spinning machine apparatus is provided which includes a vacuum housing for a spinning rotor which has a moveable housing section which forms a lid. A brake lever which serves to actuate a rotor brake simultaneously serves as a locking lever for locking the moveable housing section in the closed position such that movement of this lever from the locking position automatically actuates the brake so that the rotor is braked prior to actual opening movement of the housing section forming the lid.

Abstract: This invention relates to an apparatus for measuring and recording the changes in magnitude of a variable. The apparatus includes a recording stylus or pencil and a means for carrying a recording medium such as marking paper. The stylus or the means for carrying is connected to a transducer means which follows the changes in magnitude and provides an output to drive the stylus along the width of the paper in one direction when the magnitude is increasing and in the other direction when the magnitude is decreasing. In addition, either the stylus or the means for carrying the paper are connected to rotating means which rotate in one direction only and which are also driven by the output of the transducer. As the rotating means rotates in one direction only, the stylus will produce a straight line along the width of the paper when the output of the transducer is in one direction, and a straight line at an angle to the first line, when the output of the transducer is in the opposite direction.

Abstract: An instrument for measuring the consistency of high-consistency materials such as heavy liquids, semi-liquids, and semi-pastes which comprises a tube section flared at the bottom which is immersed vertically into a volume of the material until it has been completely covered and the inside completely filled. The tube is then withdrawn slowly and the amount of the material retained on the entire surface of the tube at the end of the drip cycle following its withdrawal is a measure of its consistency and this is weighed by means of a scale attached to the tube by a bale type handle on the tube, the latter also facilitating immersion of the tube.

Abstract: In the apparatus disclosed herein, a continuously operative sample intake is traversed along the shoreline at a preselected subsurface level appropriate for picking up effluents emanating from on-shore septic systems. The conductivity and the fluorescence of the sampled water are measured continuously, the wavelength of the fluorescence measured being chosen to determine the presence of aromatic hydrocarbons and detergent whiteners which are present in distinctive proportions in recharged septic effluents. Signal processing means are incorporated for generating an output signal which varies as a function of the conjoint deviation of the two measurements from the values thereof which are representative of background water levels.

Abstract: A self-contained unit integrally operable in conjunction with a gas meter registers equivalent standard gas volume by correcting actual gas volume for both pressure and temperature. A magnetic couple provides a drive input to the correction unit at a rate proportional to the operational rate of the meter. Separate temperature and pressure sensitive mechanisms exposed to the gas flow each provide a linear displacement proportional to changes in their absolute condition. Respective displacement of each is supplied independently to a dual input single output multiplying mechanism from which an integrated output serves to position a limiting cam in angular correlation therewith. Position of the cam effectively modifies the drive input from the magnetic couple through a crank arrangement that drives the corrected register at a rate correlated to the integrated function of absolute pressure and temperature of the metered gas.
