Abstract: A combined brake and steering system for a vehicle having hydraulic braking and hydraulic steering. A single pump is utilized to supply both the brakes and steering. Two priority valves are arranged to assure that the brakes take precedence and receive an approximately constant flow of hydraulic fluid subject to a maximum pressure. The steering mechanism also normally receives a constant flow, subject to a maximum pressure which usually is different from the other maximum pressure.

Abstract: A method for forming N conductivity-type regions in a silicon substrate comprising ion implanting arsenic to form a region in said substrate having an arsenic atom concentration of at least 1 x 10-2 As atoms/total atoms in substrate, and ion implanting germanium into said substrate region. Even though the atomic radius of arsenic is very close to that of silicon -- the arsenic radius is only 0.5% smaller -- when high arsenic atom concentrations of at least 1 x 10-2 atoms/total atoms in the substrate are introduced in the substrate, and such high concentrations are only possible when arsenic is ion implanted, then atomic misfit dislocations will occur. The implanted germanium atoms compensate for the lattice strain in the silicon to minimize dislocations.

Abstract: An electronic typewriter which has the capability of erasing characters automatically and which has the further improved capability of being able to back through unused space on the line, which results after a tabulation command, thereby allowing the repositioning of the type element over the characters typed prior to the tab command thereby allowing automatic erasure of those characters. The improvement of the typewriter as described permits the retrieving of characters from an electronic memory and the use of that memory to control the erase cycle even where the carrier position and the character to be erased are on opposite sides of space without printed characters due to a tab command. This is accomplished by the electronic control of the mechanical hardware and the ability to determine where the tab command was entered on the typing line and to prevent erasure cycles in the unprinted space until the carrier has returned to the point at which the tabulation command was entered.

Abstract: The invention concerns a process for regulating humidity in a continuously moving paper web in a papermaking machine. The paper web's humidity is measured by moving a sensor to and fro over at least a significant part of the paper web's width; signals thereby generated in the sensor by the humidity values, are used to control the devices, which affect the paper web's humidity. A technical device transforms the humidity measurements into the following secondary values: a cross profile (PN), a length variation u(k) and an estimatable coupling factor B, where the relationship <IMAGE> is used. Here DN(k) is the net value taken at the time k and the cross-position N, PN is the cross profile value in position N and Mr is a chosen reference value for the humidity. The length variation u(k) is used in conjunction with MR, used as reference value, to control signals to devices, which in the papermaking machine affect average humidity over the paper web. Additionally, a preparatory check on the effect of a hypothetical raising or lowering of the humidity reference value is conducted with the aid of the estimated coupling factor (B) and the cross profile (PN), and a simulation of the cross profile which is obtained after the hypothetical changes in reference value, is conducted and presented on, for example, a display screen.<IMAGE>

Abstract: A rock-scaling device for use in mining operations in mine galleries or in tunnel construction operations. The device is adapted to be mounted on a crane structure. The device comprises an arm (18) consisting of an hydraulically operated piston-and-cylinder unit (21) wherein is rotationally mounted a tube (24). A rod (25) is axially displaceably but non-rotationally mounted in said tube (24). The rod (25) is actuated by the hydraulic piston-and-cylinder unit for reciprocating movements inwards and outwards. Turning movements of the tube is effected by a hydraulically operated rotary member (26) and tube movements thus also cause the rod (25) to turn. At the outer end of the rod is provided a chisel-shaped member (28). This member is intended to be inserted into cracks formed in the rock and to be turned. Upon turning movement of the chisel-shaped member the arm may pivot about a pin (17), since it is supported only by a spring (19). In this manner chisel-shaped member is eased into cracks, rendering the scaling operation efficient.

Title: Coating sintered hard alloy with titanium carbide - by titanium diffusion from pack contg. titanium carbide as filler
Inventor: BROKHIN I Z
Filed: 1981-11-02
Abstract: A wear resistant titanium carbide coating is applied to a sintered hard alloy by diffusion of titanium into the article at 950-1100 deg.C in a hydrogen atmos. using a powder-mixt. comprising (by wt.) 20-60% Ti, 40-80% TiC as filler and 1-5% NH4Cl as activator. The method is useful for forming wear resistant coatings on multi-facet cemented carbide throwaway tips for machining metals. Use of TiC instead of Al2O3 as filler results in 6-18 microns thick coatings of hardness 2500-2700 kg/sq. mm. which improve the wear resistance of the tips by 4-6 times when used for machining iron and steel. Additionally, coating formation rate is increased to 10-15 microns/hr., so that no special sealed containers are required for the process, and the resulting coating is smooth and has a uniform compsn.

Abstract: Electrical conductivity of solid impregnatable materials, e.g. cellulose-based insulation, is increased by addn. of (1) a cpd. which, during the polymerisation of pyrrole and/or N-methylpyrrole, causes the formation of a polymer with electrical conductivity higher than that of the solid material, and (2) pyrrole and/or N-methylpyrrole, followed by conversion of the pyrrole cpd. to a polymer in the solid material. The solid insulant may be pressed chippings, paper, a cellulose fibrous material, (non)woven cotton, a non-woven polymer fibre material, a porous inorganic material, e.g. porcelain, or a porous synthetic, e.g. a cast epoxy. (1) is esp. a cpd. of a metal of variable valency, e.g. ferric cpds. (pref.), Ce(SO4)2, or H3PMo12040. Opt., a mixt. of an oxidising agent, e.g. H2O2, and a cpd. contg. a variable valency metal ion, e.g. AlCl3, may be used. Pref., an aq. soln. contg. 0.01-200 g of (1)/100 ml water may be used; this soln. may contain an acid. (2) may be used as a gas or liq., opt. in a solvent, e.g. an alcohol or nitrile. Polymerisation is pref. at room temp., partic. until conversion is complete. The amt. of polypyrrole in the prod. is esp. 0.1-20 wt.%. Use of the insulation is partic. in high tension equipment, e.g. oil-cooled transformers with high direct current tension level. The conductivity of the insulation is more nearly that of the oil, and can be controlled by regulating the amt. of (1). The prod. can be prepd. in a few mins., and is stable.

Abstract: A seal for container locks and the like comprises two units (1,2,3;8,14,15) which are snapped into each other. The snap action is carried out by means of a plug (14) forming part of one of the units (8,14,15) and which normally closes a cavity (13) containing an indicating means (21). When the parts are separated the plug is drawn out from this position and allows the indicating means to leave said cavity. In one embodiment the plug (14) is hollow and is closed by means of a steel pin (15) which when inserted has put the indicating means under pressure and the plug has blocking vanes (18). In another embodiment the plug is not hollow but has a weak lower portion and supports a resilient blocking ring. A steel pin floats in the cavity and can break the weak wall when an attempt to brake the seal is made.
