Abstract: ABSTRACT         In  an  electrographic  printing  apparatus,  a dielectric belt cleaning system includes counter-rotating pairs (34, 36-38, 40) of adjoining cylinders mounted to a housing (24). A vacuum source (67) forces the dielectric belt  (10)  in  free  span  against  the  surfaces  of  the cylinders which are each covered by a brush (54) including a directional raised nap.  Residual toner (88) on the belt is dislodged and drawn through a low pressure zone between each pair of cylinders leading to a filtered discharge outlet.   The  brushes   (54)   are   cleaned  by  their interengagement along adjacent cylinder surfaces where the cylinder brushes mesh and also between each cylinder brush and a rake (74) therefor fixed to the housing.

Granted: 1991-01-02
Abstract: ABSTRACT OF THE DISCLOSURE     Nonwoven fibrous elastomeric web material, including absorbent webs and fabric web material, and methods of forming the same, are disclosed.  The elastomeric web material is a hydraulically entangled coform or admixture of (1) meltblown fibers, such as elastic meltblown fibers and (2) pulp fibers and/or staple fibers and/or meltblown fibers and/or continuous filaments, with or without particulate material; such coform can be hydraulically entangled by itself or with other materials, including, e.g., super absorbent particulate material.  The use of meltblown fibers facilitates the hydraulic entangling, resulting in a high degree of entanglement and enabling the use of shorter staple or pulp fibers.  The hydraulic entangling technique provides a nonwoven fibrous elastic  material having increased web strength and integrity, and allows for better control of other product attributes, such as absorbency, wet strength and abrasion resistance.  A smooth surfaced and/or highly absorbent elastic web material, with isotropic strength and recovery in both machine- and cross-directions, can be provided according to the present invention.

Title: Method of determining the porosity of an underground formation being drilled
Inventor: CURRY DAVID
IPC: E21B44/00
Filed: 1989-07-12
Granted: 1993-04-20
Abstract: ABSTRACT          The invention relates to a method of determining the porosity of an underground formation being drilled by a rotating drill bit mounted at the lower end of a drill string.  The torque (TOR) and the weight (WOB) applied on the bit when drilling the underground formation are measured; the effect of the geometry of the drill bit on the torque and weight on bit response is determined; the porosity (phi) of the formation being drilled is derived from the measured TOR and WOB taking into account the effect of the geometry of the drill bit.  Preferentially, the porosity phi is determined from the following equation:                       TOR = (k1 + k2.phi) WOBa where k1, k2 and a are parameters characteristic of the geometry of the drill bit.

Abstract: A rail (1) of U-shaped section is used as a casing for a bar of wood. The rail has barbs on the inner walls and ribs (4, 3) at the bottom. Tracks extend on the underside of the rail, the said tracks matching tracks on the mountings (2). The rail also has a horizontal support shelf on its outer side. The rail with bars of wood are secured with the aid of the mountings on an underfloor damaged by moisture whereas a material serving to isolate the underfloor is located on the shelves. The said material rests on two support shelves (5) pertaining to the rails and situated at some distance from one another. It is also possible for an insulating material to be placed on top of the isolating material (12, 14). A new flooring material is now fixed on top of the bars. At this stage the space between the underfloor and the isolating material brought about in this way is ventilated naturally or by force. The same method can be used to prevent radon rising through the underfloor from penetrating the premises above.

Abstract: To permit dimming of a halogen incandescant lamp, or set of lamps connected to an electronic transformer circuit which receives operating voltage from a power network, rectifies the current supply and chops the rectified power to provide high-frequency alternating voltage for transformation to low voltage of the incandesent lamp, a non-current compensated choke having an inductance of at least 50 mH is connected in series between the rectifier output terminals and the rectifier system terminals, an oscillation start acceleration circuit including a CR circuit is connected in parallel with the starting circuit for the alternately operating transistors and a pair of symmetry resistors (R6,R7) are connected in parallel to symmetry defining capacitors (C6,C7), connected across the rectifier output terminals and a mid-point (M) of the oscillation transistors. The arrangement permits soft starting of the transistors, even if a serially connected phase controlled dimmer circuit suddenly connects line voltage at peak value across the rectifier, while providing for continuous energy release, even if the dimmer control is turned beyond the 90 DEG  phase angle position and, for example, to 135 DEG phase angle.

Abstract: A distribution class surge arrester comprises a core formed of distributed zinc oxide varistor blocks, aluminium blocks acting as heat sinks and as spacers providing voltage grading and required arcing distances, and terminal blocks held in face to face contact by means of a glass reinforced epoxy shell which is formed by winding a pre-preg onto the assembled blocks and thermally curing under mould pressure within an evacuated mould. The core is housed within a polymeric shedded housing which is formed by shrinking a heat-shrink shedded sleeve onto the core with a sealant provided in the interface of the core and the sleeve, and end caps are sealed to the ends of the structure thus formed. The all solid-state arrester thus formed has performance and cost advantages over conventional porcelain housed arresters and furthermore has very considerable physical strength enabling it to serve additionally as a stand-off support insulator in situations where con­ventionally separate arrester and support insulators were required.
