PURPOSE:To accurately perform the creep operation at a place such as a slope where a load is applied to a vehicle and safely perform the slope start by controlling the feed rate of fuel during the creep operation by way of a control means. CONSTITUTION:The creep operation is enabled when existence or absence of the operation of service and/or parking brakes is defected by a pair of brake sensors 3...

PURPOSE:To easily allow a slope start by automatically disconnecting a clutch, repeating small advance and recession, and keeping the stop state in appearance. CONSTITUTION:A microcomputer 21 reads the gear position of a transmission 15 by a transmission position sensor 26. In addition, a car speed sensor 26 reads the advance or recession of a vehicle and also reads the car speed in the same way. ...

PURPOSE:To restrain excessive rotation of engine and maintain better drivability by providing a detection switch detecting backward running conduction and controlling engine rotating number to less than a fixed number at the time of backward running condition detection. CONSTITUTION:In an engine control device in which engine power is transmitted to axles of a pair of right and left rear wheels th...

An apparatus for vulcanizing pneumatic vehicle tires where the tire beads, in the mounted state, are disposed on the radially inner periphery of a rim next to the essentially radially inwardly extending rim flanges. In order to obtain tires having a long service life and tire beads with a good sealing quality, it is proposed that the tire be vulcanized in essentially the proper contour for operati...

An improved rotary cutter for a web material is proposed. It has a pair of rolls adapted to rotate synchronously in opposite directions and an axially elongated knife secured to each roll to extend axially. A plurality of rolling bodies are arranged around each roll to bear the shock upon cutting. Different means for preventing the knives from hitting the rolling bodies are proposed. This arrangem...

An apparatus for the direct reduction of sulphurous iron ores with a shaft furnace, in which the ore is reduced in counterflow to the reducing gas is described, the waste gas being subdivided into two streams folllowing the furnace. One stream heats and desulphurizes the ore located above the shaft furnace in an ore bunker and is then supplied to the gas converter for heating purposes. The other s...

A dog clutch construction is provided for selectively rotationally connecting or disconnecting two coaxially arranged shafts. The dog clutch includes teeth on each shaft which are axially juxtaposed to each other. A toothed sleeve is engaged over the teeth. The sleeve is axially movable from a first position located on only one set of teeth to a second position located on both sets of teeth. A new...

A tire building apparatus comprising: an extruder having an extrusion die comprising a doughnut-shaped die member and an axially elongated die member to provide for consecutively extruding a cylindrical-shaped material downwardly from space between the doughnut-shaped die member and the axially elongated die member; a tire supporting unit for supporting a green tire into which the cylindrical-shap...

Catalyst supports, catalysts, method for the preparation thereof, and dimerization processes therewith are provided. Catalyst supports consist essentially of potassium carbonate with a crush strength of at least 5 pounds and at least one carbonaceous compound. Catalysts consist essentially of at least one elemental alkali metal deposited on the novel catalyst supports. Optionally, the catalysts fu...

In an industrial process control system, in which the process is controlled via multiplicity of I/O data points communicating with a computer system controller, errors in the addressing signals selecting the I/O data points are prevented from causing the incorrect setting or reading out incorrect data from wrongly selected data points. A multibit parity signal is generated from the address signals...

APPARATUS AND METHOD FOR PROCESSING CRABS An apparatus and method for processing hard shell crabs is disclosed, and which includes means for initially engaging and aligning the crab bodies with the path of travel through the apparatus, and then clampingly pressing the bodies against a supporting surface to maintain the orientation of the bodies during their movement through the subsequent processi...

A double-acting differential having a differential case held together by coupling elements, a drive gear fixed to the case and within the case, output shafts, side gears, differential pinions, and a spider. It also has internally splined disks connected to the side gear, and externally splined disks connected to the case, and pressure springs arranged between the differential case and one of the s...

An aromatic condensation polyimide film that is approximately 90% transparent at 500 nm, useful for thermal protective coatings and the like, and the processes for preparing same by thermal and chemical conversion are disclosed. An essential feature of the invention for achieving maximum optical transparency films requires utilizing recrystallized and/or sublimated specific aromatic diamines and d...

An aqueous frothed and filled vinyl chloride and/or vinylidene chloride polymer latex containing an emulsified plasticizer is used to coat and impregnate the back of a carpet. The carpet containing the froth is heated to drive off or evaporate the water and gel the vinyl polymer. While still hot or soft, the froth on the carpet is densified to obtain uniform dimensions or thickness. The resulting ...

Foamed resinous products having excellent fire resistance, high thermal insulation and good resistance to heat are obtained at temperatures as low as room temperature and without the need for an added blowing agent by forming a mixture of a phenolic resole having a specified reactivity, an acid hardener for the resole and, uniformly dispersed through the mixture of resole and hardener, at least 20...

Clouded acrylate surfaces are cleaned permanently. The clouded surface is first cleaned using a petroleum distillate. Subsequently, a coating of an oil-monomer modified alkyl resin, 71-78% non-volatile, is coated on the surface to prevent further clouding.
