Abstract: Process of sulfurizing a blend of 90 to 50 and preferably 88 to 70 parts by volume of triglyceride such as lard oil and 10 to 50 and preferably 12 to 30 parts by volume of an ethylenically unsaturated hydrocarbon contaning 2 to 24 carbon atoms. The sulfurization is carried out using elemental sulfur. Simultaneous sulfurization and chlorination may be effected by reacting with sulfur monochloride. Phosphosulfurization may also be carried out by addition of small amounts of a phosphorus sulfide to the sulfurized blend followed by heating at 180.degree. F. to 250.degree. F. for from 30 minutes to 10 hours to effect phosphosulfurization. The sulfurization or phosphosulfurization involves reacting at from 330.degree. F. to 445.degree. F. for 20 minutes to 10 hours followed by blowing with a gas at from 125.degree. F. to 250.degree. F. for 30 minutes to 20 hours to remove hydrogen sulfide. The simultaneous sulfurization and chlorination reaction is carried out at from 90.degree. F. to 280.degree. F.

Abstract: A synthetic sulfurized oil, useful as an additive to lubricants, and especially as a replacement for sulfurized sperm oil, is produced by reaction of sulfur, lard oil and polyisobutylene oligimers containing at least one pair of maximally crowded geminal methyl groups (e.g. "tetraisobutylene"). Preferably, sufficient sulfur to obtain a final sulfurized product containing in the range of about 5-25 weight percent sulfur is reacted with a mixture comprising about 30-90 parts by weight of lard oil and 70-10 parts of the polyisobutylene. Minor amounts (e.g. up to about 15 weight percent) of other unsaturated hydrocarbons (e.g. "C.sub.18 olefin") can also be present in the mixture.

Abstract: Method is disclosed for preparing a honeycomb insulation structure having its cells partially filled with a low density foam and a high density integral skin completely covering one edge of the honeycomb. Method comprises placing one edge of a honeycomb in an inert material; introducing a foamable or foaming substance into the cells and allowing it to rise from the surface of the inert material until it overflows slightly. The overflowing foam comes into contact with a pressure platen just above the honeycomb thereby forming the high density integral skin. The level of the material in the cell determines the thickness of the void on one edge. Structure has utility in cryogenic storage.

Abstract: Pinene can be converted to perfluoro-p-menthane in high yield by first hydrogenating pinene to form pinane, and then perfluorinating the same with CoF.sub.3. Ring cleavage of the pinane to form p-menthane is achieved simultaneously with the perfluorination in a single step to obtain perfluoro-p-menthane, a valuable synthetic blood substitute material.

Abstract: An insulator having a universal configuration can be placed around many different types of steam traps. The insulator comprises a housing having suitable openings for water drainage and testing of the trap by an ultrasonic probe, and thermal insulation. Use of the insulator results in more efficient operation of the trap and saves energy. One of the outstanding features of the insulator is its ease of installation.

Abstract: In order to obtain very close control of the flowrate of a fluid through a conduit against a predetermined desired flowrate, a pulse generator is employed to produce pulses at a frequency representing the desired flowrate, and a flowmeter issues similar pulses representing the actual flowrate. First and second difference pulse streams are digitally derived to represent the difference by which the actual flowrate either exceeds or falls short of the desired flowrate, and these difference pulse streams are applied, respectively, to count down and count up inputs to an up/down counter. The instantaneous count held within the up/down counter is translated to an analog signal by a digital-to-analog converter, and the analog signal is applied to the input of a two-wire transmitter. The two-wire transmitter drives a valve-actuating motor, such as a d-c torquemotor, to correct the valve position as necessary to obtain and maintain the desired flowrate.

The pulling tool includes a pump located in the tool housing for pulling drilling mud into the lower end of the pulling tool and discharging the drilling mud in an upward direction so as to provide a downward force on the logging tool and logging cables. Several pulling tools can be used at the same time, each being spaced at intervals along the logging cable.

Abstract: A dispensing nozzle assembly having a system for receiving the vapors displaced from a motor vehicle gasoline tank when it is being filled and an interlock system located in conjunction with the latching collar on the discharge spout of the nozzle, for preventing the dispensing of gasoline until the discharge spout is inserted into the vehicle fillpipe. The interlock system includes a valve mounted in the discharge spout in such a manner that it is actuated by the weight of the nozzle resting upon the fillpipe inlet. The valve is interconnected with the automatic shut-off system of the nozzle so that when the valve is in its open position, signifying that the nozzle is properly inserted in the fillpipe, dispensing of gasoline is permitted.
