Abstract: A thermoplastic-rubber polymer alloy contains a tough, wear resistant low friction thermoplastic such as ultra high molecular weight polyethylene, a cured rubber compound such as nitrile rubber, and a lubricant such as graphite in effective amounts to produce a composition which has good wet and dry friction and wear properties. The ultra high molecular weight polyethylene is typically utilized in a sufficient amount so as to form a continuous phase with the thermoset rubber being present as particles dispersed throughout the polyethylene as a discontinuous phase. The polymer alloy is made by dry blending the thermoplastic compound with ground thermoset rubber whereby the rubber is coated, heating and mixing the composition to above the glass transition temperature of the thermoplastic compound and subsequently cooling under pressure. The alloy can be easily transfer molded because of the lubricating action of the heated, softened plastic. The alloy is ideally suited for use as a hard bearing material due to its low coefficient of friction and low wear rate.

Abstract: Reentry disulphides are eliminated in a continuous process for treating a sour hydrocarbon stream by extracting the mercaptans contained in the hydrocarbon stream 1 with a disulphide-free alkaline solution in an extraction zone 3, oxidizing the mercaptans to disulphides in the presence of an oxidation catalyst, in oxidation zone 6, separating a major portion of the disulphides from the alkaline solution at 9, reducing the residual disulphides in the alkaline solution to mercaptans and recycling the resulting substantially disulphide-free alkaline solution from the reduction zone 12 to the extraction zone 3. The reduction of the disulphides to mercaptans may be carried out by hydrogenation or by electrochemical reduction.

Abstract: An anchor bolt assembly for securing a bolt (11) in a bore hole having a settable bonding material (41) therein utilizes a standard smooth bolt or a rebar which has a head on one end and which is threaded to receive a nut (29) on the other end. Improved mixing of the bonding material (41) and improved tensioning of the bolt (11) is achieved by attaching a rod or wire (31) to the nut or head and to a second point of attachment along the bolt. Supporting members for applying pressure against an area surrounding the mouth of the bore hole are provided with a coating of a latent lubricating material (23) which becomes an active lubricant in response to heat generated as the bolt is rotated and tensioned in the bore hole.

Abstract: A burner (6) produces combustion gases which are fed to a heat exchanger (13) for heating air supplied by a blower (16) to the passenger compartment of a motor vehicle and are then discharged into an inlet manifold (1) of the engine of the vehicle. The burner includes a fuel atomizer (9) with a fuel atomizing glow plug (92) in a combustion chamber (71) and an igniting glow plug (10) in an ignition chamber (70). In order to control the atomization of the fuel and thus its combustion, the temperature of the burner is sensed by measuring by means of a detector (100), the resistance of a resistance wire, having a postive temperature coefficient of resistance, embededded in the ignition glow plug (10). The detector (100) sends a signal to a controller (21) which controls the electric power supplied to the atomizing flow plug (92) and hence its temperature. The controller (21) also receives signals from an atomospheric temperature sensor (12) since the atmospheric air temperature also affects the temperature in the conbustion chamber (71).

Abstract: The invention consists of a convertible briefcase which can be used in two different models, each of a different size and capacity. Its technical field is thus that of purses, handbags, and briefcases, with the feature that it does not require ancillary or mechanical resources of any type for the transformation. 
     The invention is characterised by being made up of a container whose internal bottom half constitutes a closed recipient of parallelepiped section, formed on the basis of four walls of parallel pairs, two of which are narrower than the other two and joined by a bottom rib to a flat base. The interior recipient is provided with an upper closure base, opened in two halves, which can be closed by means of a zip. The upper half of the container is made up by the prolongation of the four walls which basically form the interior recipient, with the special feature that those of smaller width, when extended, form a section to cover and close the unit, and these may be joined up by means of a zip closure so as to convert the unit to one of larger size. This unit can be folded along the lines defining the internal recipient conforming the the smaller unit. The two closing bases of both recipients contain an external system of rings which allow for the adaptation of any fixing device. 
     Figures 1 and 2 of the drawings show, in turn, the smaller and larger capacity models of the briefcase. Figure 5 is a cross-section through one of the sides in figure 2, while figure 4 shows a practical example of the phase of conversion.

Abstract: In a design variant, the device comprises a magnetic field sensor (1), a voltage/current converter (2) which supplies the magnetic field sensor (1) with a supply current (i), an amplifier (3) connected in cascade to the output of the magnetic field sensor (1) and a converter (4) which is connected to the output of the amplifier (3) and which is an analog/digital converter or a voltage/frequency converter. The amplifier (3) is a correcting network whose transfer ratio in the design variants is proportional to one of the factors (1 +  delta n/n) or (1 -  delta n/n). The amplifier (3) comprises an inverting amplifier made up of an operational amplifier, a feedback resistor and an input resistor. Its gain is proportional to the ratio of the resistance values of the two resistors which are diffused into a semiconductor material of the same conductivity type as that of the magnetic field sensor (1). The two resistors are close to the magnetic field sensor (1), are symmetrical with respect to it and have approximately the same dimensions as it. At the same time, n, the charge carrier concentration in the semiconductor material, and  delta n, the change in said charge carrier concentration (n) with time in one of the two resistors, is preferably equal to the charge carrier concentration (n) in the magnetic field sensor (1), and the charge carrier concentration in the other resistor is equal to a multiple of the charge carrier concentration (n) in the magnetic field sensor (1).

Abstract: A valve arrangement for a fastener driving tool (1) of the type having a cylinder (12) and piston/driver assembly (16) for driving a fastener, a main valve (29) which, when actuated, opens the cylinder (12) to air under pressure causing the piston/driver assembly (16) to drive a fastener, a remote valve (44) which, when actuated, causes the main valve (29) to open, and a trigger actuated valve (48a) together with a workpiece responsive safety actuated valve (10a) which, when both are actuated, actuate the remote valve (44), the valve arrangement being such that the safety actuated valve (10a) must be actuated before the trigger actuated valve (48a) in order for the remote valve (44) to be actuated. The trigger actuated valve (48a) has a trigger-operated stem slidably mounted within a valve body. The body defines a chamber in which one end of the remote valve stem (62) is slidingly and sealingly engaged. Air under pressure within the chamber maintains the remote valve stem (62) in an unactuated position. A passage in the tool body connects the trigger actuated valve (48a) to the safety actuated valve (10a). The chamber is connected to said passage when the trigger actuated valve (48a) is open. The passage is connected to atmosphere when the safety actuated valve (10a) is open. One of the trigger actuated valve (48a) and the safety actuated valve (10a) is an on-off valve and the other is a pressure controlled valve. The pressure controlled valve precludes connection of the chamber to atmosphere via passage to shift the remote valve stem (62) to its actuated position unless the safety actuated valve (10a) is opened prior to the opening of the trigger actuated valve (48a).
