PURPOSE:To simplify a device in structure as well as to aim at the promotion of its lightweightiness, by inserting a collet into a shaft of a drum to be driven, while clamping it to a collet body and afterward, securing a motor tight to a worm reduction gear via a flange coupling. CONSTITUTION:In a collet 9, its outer circumferential surface is formed in section taper form, having a slit alpha in ...

PURPOSE:To make disassembling and assembling for a gear case performable without imposing excessive force on an idle gear, by having the idle gear to be interposed in a gear train between a shaft pivotally supported on a split surface of a gear case and a shaft pivotally supported on a halved part of one side supported by the halved part of the other end. CONSTITUTION:A driving shaft 9 is pivotall...

PURPOSE:To prevent a transmission case from becoming longer as well as to aim at the promotion of its miniaturization and lightweightiness, by installing an oil passage to be interconnected to both of the oil passage of a drive pinion shaft and a lubrication flange being attached to the transmission case. CONSTITUTION:In a lubricating part of a hydraulic clutch for a running transmission mechanism...

A shape-forming apparatus (10) for carcases of radial tyres is described. In the shape-forming apparatus (10) the expansion of the forming apparatus is exactly controlled by a central, expandable bellows (16) in which a narrow section of the, in the axial direction, central region of the forming apparatus starts the expansion. Preferably an arrangement of wires (17) extending in the axial directio...

Polyurethane foams prepared from the reaction of polyester polyol with organic isocyanate have improved flame retardance and dripping ember retardance by incorporation of an additive comprising (1) halogenated flame retardant, and (2) organic solvent soluble glycoluril-formaldehyde material.

The processibility and initial mechanical strengths of hydraulic cement compositions, e.g., Portland cement, are improved by formulating therewith an adjuvant comprising (i) a water-soluble salt of the condensation product of an aromatic sulfonic acid with HCHO (formulated either alone or in admixture with a water-soluble salt of an aromatic sulfonic acid which has not been condensed with HCHO), (...

1355373 Laminated products W L GORE & ASSOCIATES Inc 5 May 1971 [21 May 1970] 13178/71 Headings B5B and B5N [Also in Divisions B2 C3 and H1] A laminate comprises a first shaped article bonded to a second shaped porous polymeric article the polymer containing units derived from tetrafluoroethylene and the porous polymer having a microstructure (i.e. which cannot be resolved with the naked eye) char...

In order to improve the accuracy of borehole survey systems utilizing probes with inertial components including inclinometers, two ring laser gyro units are included to provide rotation information 56, 58 to the system. When the probe is moving in a borehole, inclinometer information 50, 52, 54 is used 78 to produce a synthetic rotation signal 80 to take the place of a third gyro and the earth's r...

A method of testing pipe sections at an oil rig floor by means of an internal pipe testing tool (7) and a pressurized gas containing helium in a ratio of helium to a carrier gas of at least about 1:2856 by volume. The gas is pressurized in a hydraulic accumulator (2) remote from the rig floor. The pressurized gas actuates the test tool (7) at substantially the same pressure as is used for testing ...

The reflectors, for example for automotive vehicle head lamps are reflectorized by evaporating aluminum thereon in a vacuum vessel at a vacuum of about 10-7 bar; thereafter, and without removing the reflectors, a gaseous monomer is introduced raising the pressure to about 5 x 10-6 bar to deposit a protective layer by polymerization from the gaseous phase. The monomer gases, preferably, are low mol...

An electrically heated window for a vehicle includes a smooth surfaced transparent sheet having a plurality of spaced electric resistance heating conductors on the surface thereof. A humidity detector is provided on the inside surface of the sheet and includes two sets of conductors standing in relief above the surface of the sheet and each having substantially the shape of a comb with the teeth o...

A building element is made by moistening a mixt. of a binder, one or more cellular mineral fillers, and opt. other conventional additives with water to give a damp mortar; introducing the mortar into a mould and pressing it; and removing the shaped element after a hardening time at which it is at least in the half-hardened state. - Pref. the wt. ratio binder: cellular fillers=1:7 to 1:10 and the f...

The present invention provides a method of producing articles containing cement and reinforcing vegetable fibres. Hitherto, the fibres had to be treated chemically in order to ensure sufficient bonding between the cement and the fibres. The present invention removes the need for the chemical pre-treatment of the fibres and involves a two stage process of mixing the cement powder, water and the fib...

The apparent size of the image produced by a clocked solid-state television imager is controlled by the read clock rate. In a camera using such an imager the clock rate is adjusted to provide an effect similar to zoom. Where a plurality of imagers are used in a color camera, differential control of the clock rate as between the imagers allows compensation for lens chromatic aberration thereby prov...
