PURPOSE:To obtain an over drive device of low cost having a simplified construction capable of applying the over drive by depressing a manual switch in any gear reduction ratio and releasing it by applying a clutch pedal.

PURPOSE:To improve characters for speed change operation by equipping with a power transmission mechanism including main and sub speed change mechanisms, an actuator, a hydraulic fluid source and passages therefor, a manual switch, a clutch-cut detecting switch and solenoid valves. CONSTITUTION:When a movable terminal 69 is switched to a terminal 67 or 68 by an operation of a manual switch 66 and ...

A method of making a cheese vat from a synthetic plastics material and having a perforated wall through which whey can penetrate includes producing the perforations in said wall by means of a laser beam. The perforations may be cylindrical or holes of varying diameter.

The invention provides an improved method for producing a filler-loaded thermoplastic resin composite by mixing a thermoplastic resin with a filler, making it possible to be applied to molding machine such as extrusion and injection molding machines without the disadvantage of segregation between the resin and the filler otherwise inevitable leading to inferior uniformity of the shaped articles. T...

Lead storage batteries can be more readily replenished with water-soluble expander material, which becomes depleted during operation, if it is in the form of a dedusted granular material. The granulation is carried out by mixing the powdered expander and water as binder. The dyestuff alizarin (as the sodium salt of the sulphonic acid form), which is known as an expander, can be particularly succes...

Relatively long plastic microfilaments made from a plastic composition. The plastic microfilaments may be used to make reinforcing, filler materials and fabrics. The microfilaments are made by forming a liquid film of plastic across a coaxial blowing nozzle (5), applying a blowing gas (10) at a positive pressure on the inner surface of the plastic film to blow the film and form an elongated hollow...

The invention relates to a device for the protected input of a sequence of data messages, associated with a process, in a computer with serial/parallel convertor preceding the input. The device can be used for detecting, for example, component failures in the parallel section of the serial/parallel convertor and in the computer input which lead to unchangeable logic states at particular bit locati...

1. Process for the preparation of highly elastic cold-curing polyurethane foams from at least difunctional polyisocyanates, polyols with at least two hydroxyl groups per molecule, of which on average at least 40% thereof are primary hydroxyl groups and the equivalent weight per hydroxyl group is 700 to 3000, catalysts, blowing agents and stabilisers as well as, if appropriate, conventional additiv...

A tape coated with an adsorbent and impregnated with a processing solution which includes silver nitrate, an acid, an alcohol and a glycol is a sensitive detecting means for hydride gases and is stable upon exposure to light.

A safety binding is provided which is mounted on a ski and serves to retain a ski boot. The safety binding has a cheek which, with the aid of an elastic device, is retained in a predetermined position bearing against a bearing part directly or with the aid of an adapter, specifically at three points in the position of rest, that is to say an upper middle and two lower bearing points arranged symme...

A port cap for attachment to an inlet or an outlet port of a device, especially a medical device such as a cardiotomy reservoir, venous reservoir, blood oxygenator or blood dialyzer. The port cap comprises a hollow body member having a wall at its first end, a second end which is open, and a hollow interior. The closed end of the body member carries a hollow projection having a first end which is ...

Relatively long microfilaments made from a low heat conductivity glass composition. The microfilaments are used to make insulation and/or filler materials. The microfilaments are made by forming a liquid film of molten glass across a coaxial blowing nozzle (5), applying a blowing gas (10) at a positive pressure on the inner surface of the glass film to blow the film and form an elongated hollow tu...

Relatively long metal microfilaments made from film forming metal material. The microfilaments can be used to make superior high strength structural materials and/or can be used as reinforcing materials in plastic and rubber compositions. The microfilaments are made by forming a liquid film of molten film forming metal material across a coaxial blowing nozzle (5), applying a blowing gas (10) at a ...

A limited slip differential comprising bevel gears (12, 13, 14, 15) and conical surfaced noses (18, 19) provides frictional drive lock up. Known limited slip differentials are wasteful of energy and require periodic adjustment. These problems are overcome by providing a limited slip differential which comprises a housing (1) for mounting in a rotatable manner in a casing. A first pair of bevel gea...

An additive composition has been formulated which accelerates the setting time, and also improves the compressive strength of Portland type cement, mortars and concretes. The additive composition consists essentially of a concentrated aqueous solution of calcium nitrate and a waste byproduct stream of a mixture of polyethanolamines (referred to as "triethanolamine bottoms") to which solution is ad...

Thermoplastics film having a thickness not greater than 100 microns preferably not greater than 50 microns comprising at least 70 wt% high density polyethylene (density not less than 935 kg m<3>) characterised in that the film has a total haze (ASTMD 1003-61/70, Procedure A) less than 50% and a clarity (ASTMD 1746-70) of at least 25%. The film can be manufactured by pressing raw polyolefin film (1...

In an installation having a group of independent shop scales, each set of shop scales consists of a weighing part receiving the goods and the weight of which must be determined, and of an evaluating part receiving its measurement signal and comprises memories with an input device, a computer and a display and possibly a printer. The memories also comprise PLU memories which contain predetermined u...
