An internal combustion engine includes four cylinders arranged concentrically about a driving shaft and each having two opposing pistons which are linked to wobble elements via respective connecting rods. The wobble elements are supported by the driving shaft and transmit the movement of the pistons into a rotational movement of the driving shaft. Each wobble element consists of two portions which...

The system has a single acting, multistage, synchronous hydraulic jack having a trapped oil space which provides the required synchronism. The hydraulic system includes a first external pump in fluid flow communication with an oil space disposed between the outer cylinder and an intermediates section. Oil leakage from the trapped oil space is detected when the sections are retracted. The next ti...

A blade assembly (10) comprises first and second blades (24 and 24 min ) which are pivotally mounted to the rest of the assembly (10). This enables the span of each blade to be altered in response to the amount of shaving force generated by the user.

In order to maintain an intensive mixing, it is characteri...

A sealed galvanic cell comprising a container (30) having a base, an upstanding wall (32) and an open end defined by the upstanding wall (32); a cover (4) having a peripheral sealing portion (14), a top surface (5), and an undersurface (7) including a nonsealing area, the cover (4) having at least one vent aperture (8) through the top surface (5) and the nonsealing area of the undersurface (7); th...

The urethane coating agent is prepd. by (a) reacting aliphatic diisocyanate with polyol and bisphenol A 10-50% (to total solids) and MDA 0.5-1% (to total solids) in lower b.p. solvent, (b) neutralizing with acid and (c) distg. off solvent. Thus, e.g. vacuum dry polypropyleneglycole (mw ca 2000) and polyethertriol (mw ca 3000) for 30 min at 100 deg.C, put dried polyols, bisphenol A, 1,6-hexanediol...

A process for coating a transparent article of high optical quality, which comprises spraying a polymerizable reaction mixture of reaction components on the transparent article to form a homogenous coating layer of high optical quality, wherein the mixture of reaction components is sprayed by high-speed centrifugal spraying; and polymerizing the resultant coating layer.

The present invention concerns an erosion grinding device for feeding a lime sludge into a water course for the purpose of increasing its pH value. Water is taken continuously from the water course through a feed pipe 4 and into a container 1 and is spread via a rotor 5 into a channel 6 at the bottom of the container 1. Limestones from a magazine 8 are simultaneously fed down into the container 1 ...

Guides are provided for the lifters so that they engage the crates either for stacking them or breaking down the stack. The lifters are fitted on vertically controlled frames which are raised by compressed air cylinders, and coupled for parallel-controlled movement. - The coupling between the frames is by toothed belts running over gearwheels.

The heel formation (2) allows a pallet to be pushed or dragged on its base only when one or both fork arms are engaged with the underside of the pallet. The heel formation comprises an eccentric (20) with a pick-up spike (24). In the pivoted backwards position of the eccentric the pick-up spike is located beneath the contact plane (10') of the fork arm but above its surface. - Thus, the eccentric ...

An apparatus provides a swivelless connection of first and second fixed positions on respective first and second structures. The structures are relatively rotatable about a common axis, through a length of flexible conduit defined by first and second space portions thereof respectively connected to the first and second fixed positions and predetermined in accordance with the extent of relative rot...
