A time-base conversion system including a first clock generator for generating a read clock based on a reference signal, a second clock generator for generating a write clock by dividing the read clock, a memory, a circuit for writing video data in the memory based on the write clock, a circuit for reading the video data recorded in the memory based on the read clock. and a time-base compressor fo...

The invention relates to a method of rapidly transporting a drug to the epidermis and accumulating and maintaining the drug therein for a prolonged period of time comprising administration of a therapeutically efective non-toxic amount of the drug with an effective amount of hyaluronic acid.

The invention discloses a combined sample dispenser and order form comprising a backing sheet that may be prepared from cardboard, and a generally planar retaining member, such as a clear plastics sheet, attached to the backing sheet along at least a portion thereof. The retaining member or plastics sheet defines a distention or pocket along a portion of its broad surface, that may contain samples...

A process for enriching a liquid with oxygen by introducing the liquid into an oxygen enriching vessel (1), subdividing the liquid, subjecting the interior of the vessel (1) to an oxygen pressure of at least about 20 psi, conducting the introduced water in a substantially flowing contact with the oxygen, and recovering the water under oxygen pressure when it is to be bottled. The process is carrie...

The invention concerns a bone implant and finishing cutter for prosthetic stump of the screw type. This has a tapered truncated conical neck portion 1, a threaded cylindrical body 2, a tip portion 3 with a curved profile. On the inside, the implant has a blind axial hole 4 presenting an external trunk 4a and an internal trunk 4b. The external trunk 4a is circular and has a cylindrical threading, a...

An apparatus for the control of an electrochromic window having a three-electrode structure (2, 8, 5) comprises a comparator (12) to maintain within safe limits the potential difference of the electrode (2) and the reference electrode (5), and a shunt unit (16) to switch off the power supply when the current falls below a lower limit and a unit for controlling the colouring density on the basis of...

The invention consists of an electromagnetic transducer comprising a long-handled support 1 with an oblong cross section divided into one or more sections, possibly stacked together, on each of which are placed two or more staggered windings which, when current flows through them, generate three-dimensional magnetic fields with preferential orientation.

A device for artificially ageing and/or finishing fabrics comprises a roller brush (5) equipped with bristles (6) fashioned from carbon or aluminium fibre reinforced nylon, which is positioned over the path followed by a web (2) of fabric advancing from an infeed point (3) to an outfeed point (4) in such a way that the bottom generator of the rolling surface makes contact with the fabric. As the b...

The method involves placing a request (10) for synchronisation of a mobile unit with a control station. A logic system determines if synchronisation has been previously achieved (12). If synchronisation has not previously been achieved, a full range of synchronisation procedures (18) is initiated. If synchronisation has been achieved previously, the length of time (14) since the last synchronisati...

The method involves introducing grease at relatively high pressure from an automatic lubricating machine into a lubricant barrier via a link piece to lubricate the axle for preventing the escape of the prod. being transported.

The U-shaped hanging element for the vertical assembly of sheet-like objects, pref. heating radiators, comprises a waist section. The waist section has cavities or drilled holes used to assemble one or more arms. The arms are extended from the end sections of the waist section in accordance with the height of the sheet-like object. The arms are provided with grooves to firmly grip the edges of the...

The lock arrangement comprises a manoeuvre body (2) for manually setting the lock from inside or outside the vehicle, designed to adopt various positions depending on the actual lock position. A link part (3) is coupled with the manoeuvre body. A strike part (4) is joined to the link part. A block part (9) is provided for preventing deactivation of the lock after it has been set to an activated po...

The collapsible table supported on an undercarriage comprises a first pair of sheets that are movable relative to one another, over which a conveyor belt runs. The interconnected first ends of the sheets are present in a first operative connection with the undercarriage and can be raised or lowered w.r.t. the undercarriage between a first horizontal position and a second position in which the firs...
