A cement mix based on an inorganic hydraulic cement, for example, Portland Cement, an air-cooled blast furnace slag and micronized silica, for example, silica fume produces concretes having strength characteristics superior to those achieved by the cement alone; furthermore this cement mix is superior to a corresponding mix based on the inorganic hydraulic cement, and the air-cooled slag without t...

A gas assisted injection molding apparatus includes a molding injection assembly comprising an extruder barrel having an elongated screw ram that is axially and rotatably positioned therein. A quantity of gas is introduced into a charge within the extruder barrel to form a combined charge of plastic and gas prior to the combined charge leaving the extruder barrel. In one embodiment, the gas enters...

A locking arrangement has a plurality of cylinder locks having a cylinder core (14) in an outer core (13). The cylinder core (14) can be actuated by rotation by means of a master key or a suitable individual key (16'). The outer core (13) is rotatably supported in a cylinder housing (12). Spring-loaded tumbler pins (21a to 26c) which are divided into different segments (a, b, c) are arranged in th...

In accordance with the principles of the invention, a surveillance radar is provided with a rotating, frequency squinting, end-fed slotted array antenna, which is caused to transmit a plurality of different carrier frequency pulses for successively illuminating specific antenna beam positions during rotation of the antenna. Upon reception of each radar signal return, a signal processor responsive ...

A liquid ejection head includes an ejection outlet for ejecting liquid; a bubble generating region for generating a bubble; a movable member disposed faced to the bubble generating region and movable between a first position and a second position which is farther form the bubble generating region than the first position; a liquid supply passage for supplying the liquid to the bubble generating reg...

An apparatus for pumping blood includes an elongated housing dimensioned to be at least partially positioned within the heart of a patient, a rotating member supported for rotational movement within the elongated housing and a drive mechanism for imparting rotational movement to the rotating member. The elongated housing includes an outer wall, a first inlet port for permitting blood to enter the ...

A Liquid ejecting method for ejecting liquid using a bubble, includes using a liquid ejecting head having an ejection outlet for ejecting the liquid, a bubble generating region where a bubble is generated in the liquid, a movable member which is disposed faced to the bubble generating region, and which is displaceable between a first position and a second position farther from the bubble generatin...

This specification discloses a liquid discharging method of using a head having a first liquid flow path communicating with a discharge port, a second liquid flow path having an air bubble creating area, and a movable member having a free end on the discharge port side and disposed between the first liquid flow path and the air bubble creating area, to create an air bubble in the air bubble creati...

In a system for inspecting containers, a container is held in stationary position and rotated about its axis. Light energy is directed onto the container as it is rotated, and a camera obtains an image of the container illuminated by the light energy. The container image, consisting of a plurality of pixel data bytes each forming a portion of the image, is directed serially and in sequence to a pr...

A sports shoe, particularly for skates, includes a rigid shell, and a soft innerboot; separate straps for connecting the innerboot to the rigid shell are laterally rigidly coupled to the innerboot and at least partially surround the shell. First and second flaps of the innerboot are fastened to the straps which advantageously do not affect the metatarsal and/or foot instep regions.

A machine and a method for making a plastic film pouch and attaching a spout thereto is described. Two overlaid film sheets are guided adjacent a spout base positioner to position a dispensing spout spaced adjacent one of the two overlaid film sheets at a predetermined position with respect to a sealer device. One of the overlaid film sheets is displaced in the area of the sealer whereby the spout...
