Abstract: A probe for measuring the viscosity and/or temperature of high temperature liquids, such as molten metals, glass and similar materials comprises a rod which is an acoustical waveguide through which a transducer emits an ultrasonic signal through one end of the probe, and which is reflected from (a) a notch or slit or an interface between two materials of the probe and (b) from the other end of the probe which is in contact with the hot liquid or hot melt, and is detected by the same transducer at the signal emission end. To avoid the harmful effects of introducing a thermally conductive heat sink into the melt, the probe is made of relatively thermally insulative (non-heat-conductive) refractory material. The time between signal emission and reflection, and the amplitude of reflections, are compared against calibration curves to obtain temperature and viscosity values.

Abstract: The present invention concerns alkyl aryl carbonyl compounds that possess anti-infective activity. The compounds of the invention can be used to target specific nuclear localization signal, thereby blocking importation of specific proteins or molecular complex into the nucleus of a cell. The invention encompasses methods of use of such compounds for treatment or prevention of infectious diseases, such as parasitic and viral diseases, including, for example, malaria and acquired immunodeficiency syndrome. The use of the compounds to detect certain specific protein structures which are present in nuclear localization sequences is also taught.

Abstract: A high pressure rotary valve including a housing with inlet and outlet openings and a rotor and blade assembly within the housing for moving flowable solid material through the valve. The chamber containing the rotor assembly is defined between a pair of shrouds which move relative to a wall portion of the housing. The periphery of each shroud is ground and hard coated and this periphery is engaged by a first lip seal or multiple thereof supported by the housing. An end plate is located around the rotor shaft at each end of the housing and second lip seals engage ground and hard coated surfaces of the rotor shaft. Pockets defined between the shrouds and the end plates are adapted to be pressurized to create a back pressure resisting movement of material out of the housing chamber in the direction of the rotor shaft. Angular contact bearings support the rotating shaft with respect to the housing.

Abstract: A method of electrically welding a part such as a bolt around a bore of a composite sheet comprising an intermediate layer of a substantially insulating material disposed between two metal layers. Said sheet is pre-heated in the vicinity of said bore in order to remove said substantially insulating material therefrom, after which said part is welded onto said sheet by a conventional resistance spot welding method. Preferably, said pre-heating operation is conducted by passing an electric current between a counter-electrode applied to the sheet from the same side as said part to be welded, in the vicinity of said bore, and an electrode applied on said part to be welded.

Abstract: A trunnion suspension arrangement for a vehicle featuring a pair of generally parallel frame rails, such as a transport trailer, includes, for each frame rail, a trailing beam with a leading portion and a trailing portion. A hanger is attached to the frame rail and the leading portion of the trailing beam is pivotally connected to the hanger by a spherical bearing. An air spring and a shock absorber are connected between the trailing portion of the trailing beam and the frame rail. An axle is connected to the trailing beam between the hanger and the air spring. A bumper featuring arcuate side members is attached to the trailing portion of the trailing beam so that it partially surrounds the air spring. A cage, which is connected to the frame rail, surrounds the bumper and features slide pads that are engaged by the arcuate side members of the bumper to limit transverse horizontal travel of the trailing portion of the trailing beam.

Abstract: This cylinder, which may be entirely pneumatic, has two working pistons 26 and 27 linked to a working rod 28, slidably mounted on which are two small auxiliary pistons 37 and 38 which can be displaced in an auxiliary chamber 35. The latter, being permanently supplied with a compressed gas, can cause the return, by means of the piston 38 or 37, of the fitting 26-27-28 to an intermediate position shown in the drawing, respectively from a fully extracted position (towards the right) of the rod 28 or a fully retracted position (to the left) of this rod.

Abstract: A rotatable handgrip twistshifter (10) mountable coaxially about a bicycle handlebar (20) that abruptly or discontinuously increases the mechanical advantage when shifting a front derailleur from a smaller to a larger chainring. A control cable (86) is slidably connected to the handgrip (12) such that during rotation of the handgrip (12) to effect gear shifts from the middle to larger chainrings of a triple chainring crankshaft (40, 41, 42), the cable (86) is abruptly dropped toward the handgrip axis of rotation thereby increasing the mechanical advantage or leverage of the shifter (10). Alternatively, the control cable (86) is slidably connected to the pivot arm (114) of a front derailleur such that during rotation of the handgrip (12) the cable (86) is deflected away from the derailleur pivot axis (207), likewise, increasing the mechanical advantage of the derailleur.
