Title: A mandrel rod or plug for a rolling line for the manufacture of seamless tubes
Inventor: STAAT KARLHANS
IPC: B21B25/04
Filed: 1985-10-29
Abstract: A mandrel rod or a plug for a rolling line for the manufacture of seamless tubes, has a coaxial longitudinal bore 9 for the feeding and discharging of coolant, such as water, and into which bore a guide element 3 for conducting the coolant extends. In order to obtain improved dissipation of heat, this guide element 3 is connected to the internal wall of the longitudinal bore 9 in a thermally conductive manner, and the guide element 3 is made from a material having particularly high thermal conductivity (e.g. copper). Hence, it is possible to substantially increase the size of the heat-transferring surfaces and to increase the quantity of heat dissipated. Mandrel rods and plugs constructed in this manner may be subjected to greater mechanical and thermal stresses. <IMAGE>

Title: Absorbent articles with dual-layered cores
Inventor: WEISMAN PAUL THOMAS
IPC: A61F5/44
Filed: 1986-05-14
Abstract: The present invention provides absorbent articles, such as disposable diapers, which utilize substantially water-insoluble hydrogel material to enhance the absorbent capacity of such articles. In these articles, the hydrogel material, combined in particulate form with hydrophilic fiber material, is primarily placed in a lower fluid storage layer of the absorbent core of the article. Such a fluid storage lower layer of the absorbent core is placed underneath an upper, preferably larger, fluid acquisition/distribution layer containing little or no hydrogel. This lower fluid storage layer is positioned in such a manner that at least about 75% of the hydrogel in the lower layer is found in the front two-thirds of the absorbent article and such that at least about 55% of the hydrogel in the lower layer is found in the front half of the absorbent article. Absorbent articles of this type make especially effective and efficient use of the hydrogel material and may also provide a diaper rash control benefit. Absorbent cores of the type utilized in such articles are also disclosed. <IMAGE>

Title: An automatic system for selecting 4-wheel drive when braking a farm tractor
Inventor: DREW MICHAEL JAMES
IPC: B60K23/08
Filed: 1988-05-03
Abstract: A farm tractor which has the facility for selection of 2-wheel or 4-wheel drive has a manually operable supplementary switch (40) which, in conjunction with the conventional 2-wheel/4-wheel drive selector switch (14) and the back or "brakes off" contact (30) on the brake lights switch (22), ensures that when the tractor is being driven in 2-wheel drive mode, the solenoid valve (10) in the oil pressure circuit of the transmission clutch actuating motor is de-energised as soon as the brake pedal is depressed, so that the braking effort applied to the rear wheels is also transferred through the transmission clutch to the front wheels. A back-up circuit includes the handbrake lever switch for ensuring that 4-wheel braking is maintained when the driver takes his foot off the brake pedal. For tractors with dual brake pedals for selective braking of either rear wheel, a pedal interlock sensor (88) is wired into the 4-wheel braking circuit to give warning of failure to interlock the pedals when running in 2-wheel drive mode with the supplementary switch (40) set to the "road" position (42-46). <IMAGE>

Title: Infra-red image detector systems
Inventor: HOWORTH JONATHON ROSS
IPC: H04N5/225
Filed: 1988-12-07
Abstract: The detection of infra-red image radiation using cheap, high resolution semiconductor array photodetector devices (made of silicon, say) is frequently found to be difficult or impossible because such radiation does not possess sufficient energy to excite electrons in the photodetector material. A possible solution to this problem involves using the IR radiation to produce, via an IR scintillator 23 such as one based on certain refractory metal sulphide materials, radiation of a shorter wavelength that can be absorbed by, and so excite electrons in, these cheap photodetector devices 26. The invention thus proposes an imager sensitve to IR radiation which comprises an IR scintillator (or phosphor) coupled face-to-face eg via fibre optics 25, with a suitable photodetector such that the visible light output generated by the former is received by the latter. The photodetector may be a photoconductive device (eg. a vidicon or CCD camera) or a photoemissive device (eg. an image orthicon or image intensifier, Fig 3). <IMAGE>

Title: Surface acoustic wave convolver
Inventor: OKAMOTO TAKESHI
IPC: H04L27/227
Filed: 1989-06-15
Abstract: A differential phase shift keying convolver comprises a piezoelectric substrate having input transducers (10, 11) at its ends with a plurality of tracks therebetween, at least one track providing an opposite phase convolution output. Each track includes two output gates (12, 13 or 14, 15 or 16, 17 or 18, 19) spaced at the center for differential phase shift keying demodulation. Among these output gates, some gates selected in accordance with the phase relationship between convolution outputs are connected to provide sum and/or difference outputs of the convolution signals. The opposite phase convolution outputs can be produced by arranging at least one (11) of the input transducers (10, 11) in a step-like configuration, by using multistrip couplers, or by providing a metal film in a selected position of the travelling path of surface acoustic waves for application of a control voltage. <IMAGE>
