Abstract: An apparatus for enabling manual alignment of a flexible sheet in a sheet transport device having automatic detent. An incremental stepping motor providing document detent drives a platen and a tractor feed apparatus via a unique drive train. The drive train includes a first gear rotatably mounted on the platen shaft, a second gear secured to the platen shaft inboard of the first gear and a motion transfer plate slideably and rotatably received on the platen shaft. The motion transfer plate has a pair of arcuately shaped beveled gear surfaces normally engaged with a beveled inner gear surface of the first gear when the transfer plate is in a first position on the platen shaft. The beveled gear surfaces are joined by a pair of wall surfaces which are embraced by a pair of arms integral with the second gear. The motion transfer plate is secured to a control shaft having an adjustment knob, the control shaft being slideably received in a bore in the platen shaft and normally biased by a spring to the first position. The sheet is aligned relative to the detent position by displacing the control shaft inwardly until the motion transfer plate is disengaged from the first gear and by rotating the transfer plate by means of the knob and control shaft to adjust the angular position of the platen, the second gear and the tractor feed apparatus relative to the stepping motor detent position. Upon release, the control shaft and motion transfer plate return under the action of the spring to the first position.

Abstract: A thermostat including a housing assembly, a snap-acting thermally responsive actuator, and a control switch is disclosed having a switch operating arrangement coacting with the switch and the actuator. The switch operating arrangement includes a lever structure hinted to the thermostat housing assembly for transmitting motion between the switch and the actuator by pivoting about the hinge. Heat transfer to the hinge is minimized so that movement of the lever is not impeded by the effects of heat on the hinge. The lever structure slidably engages the switch during movement about the hinge resulting in gradual wearing away of the switch engaging lever portion which compensates for normally occurring switch contact erosion.

Abstract: Power transformers and inductors with windings of bandlike conductor material have large supplementary losses in the region near the ends of the winding. This is due to the fact that the leakage flux going through and between the windings and primarily axially directed gets an increasingly larger radially directed component toward the ends of the windings, which generates eddy current losses in the conductor material. In order to reduce these losses, the inside of the windings 3 is configured with a portion 5 situated closest to the core leg 1 with an axial length which is greater than the length of the other portion of the winding. This portion functions as a flux-steering shield and the shield is configured such that it has decreasing axial length with increasing radial dimension. <IMAGE>

Abstract: A press for forming a traveling compacted web from initially uncompacted material has upper and lower continuously traveling metal belt spans vertically interspaced so the material can be carried between the spans. Each span has means for directly heating it conductively and for pressing it towards the other span for compacting and heating the material when carried between the spans. Side edge portions of the spans overhang the heating and pressure means to protect the latter from being contaminated by the material while it is in its uncompacted condition and during its compaction. These overhanging portions are not heated directly and are colder than the balance of the spans during operation of the press. Normally this results in the side edge portions being stressed undesirably by tension and other stresses. To overcome this, the side portions of the belt spans are made so that they are longer when the belts are at ambient temperature, so that when the belt areas between the side edge portions are heated with consequent longitundinal expansion, the side edge portions are substantially freed from tension and other stresses.
Patent SE-7905357-L (SE)
IPC: F16L13/16
Filed: 1979-06-18
Abstract: A tube fitting assembly is disclosed wherein a ductile metal tube is forced into first and second orifices within a fitting. The tube is closely received within the first orifice and the second orifice is larger so that the axial force on the tube axially contracts the tube to form a radially expanded bead on the tube substantially filling the second orifice. This establishes a fluid tight seal between the tube and the fitting and also retains the tube in the fitting. An annular deformable seal member is also provided between an outer surface of the tube and an inner surface of the fitting and this seal may be a rubber-like O-ring or a composition material which is more yieldable than the material of the tube and fitting, may be set up from a liquid or plastic sealant material, or may be a deformable wall of the fitting. The force used to axially contract and radially expand portions of the tube is also utilized to compress the deformable seal between an outer surface of the tube and an inner surface of the fitting to make doubly sure of a good fluid-tight seal. The tube fitting assembly is thus able to withstand higher pressures, suddenly applied pressures, corrosive fluids, and extreme and rapid changes in temperature, with only a negligible number of failures of the assemblies. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: A method for producing cross-sectional images using an ultrasonic imaging unit operating on the pulse-echo principle, which unit includes a transducer system having a stationary elongated array of adjacent transducer elements with transverse electrode segments adjacent one another on one side of the array. Successively and cyclically selected groups of adjacent elements are energized to produce an ultrasonic beam as a result of pulsed signals being applied to the corresponding electrode segments. Focussing of the ultrasonic beam produced by each group of the transducers is effected by having the transmitter signals applied to the electrode segments or subgroups thereof, and/or the echo-signals derived by the electrode segments from the reflected energy, time shifted relative to one another, in which each transmitter or echo-signal has a time shift associated thereto which is a function of the distance between the corresponding electrode segments (or subgroups of segments) and the center of the group of transducers.
