The lead seal consists of a lead-sealing member with a predetermined breaking point (8) and of a guide (17, 21), provided in the housing (2, 4), with a catch for receiving the lead-sealing member and for preventing its removal from the guide. The lead-sealing member has an elongate basic body (15), is provided with an elastic locking projection which projects beyond this basic body laterally and i...

An electrode device intended to be temporarily introduced into the body of a living being and to essentially locally treat or electrically measure biological body tissue therein in order to, after performed treatment or measurement, be removed. Said electrode device includes an electrode part (1), provided with an opening to its centre and insertable into the body tissue to be treated or measured,...

A dental impression tray has approximately the form of the upper or lower biting surfaces and is made of thermoplastics material. The dental impression tray may be used to produce a functional impression of the upper or lower biting surfaces, including an occlusal impression, and is further suitable, in combination with a suitable lining material, as a dental guard for sportsmen.

A composite container is disclosed having a synthetic plastic end closure member spin-bonded to the thermoplastic synthetic plastic inner liner layer of a composite container body wall. The synthetic plastic end closure member includes annular downwardly depending inner fin and outer chime portions which are concentrically spaced to define therebetween an annular groove. One of the body and end me...

PCT No. PCT/JP82/00395 Sec. 371 Date May 26, 1983 Sec. 102(e) Date May 26, 1983 PCT Filed Oct. 1, 1982 PCT Pub. No. WO83/01271 PCT Pub.

Novel peptides are provided having substantially the same sequence as immunologically significant fragments of AIDS-related viruses. The polypeptides can be used as reagents in the determination of exposure of a human host to the virus. Of particular interest is the use of polypeptides in screening blood products.

A dry ionic process for gold plating substrate articles 5 comprises suspending an article from a holder 2 in a vacuum chamber 1 above a heated bath of a gold-based plating alloy 3 and applying a voltage from an electrical supply 4 between the articles 5 and the bath 3 to deposit vapour of the alloy. The invention lies in the use in the bath of a gold- based alloy containing at least one of the fol...

A bass-reflex loudspeaker system in which, by the addition of a corrective network (7) to an arrangement of a transducer (1) accommodated in a bass-reflex enclosure (2), which transducer is dimensioned such that it cannot be bass-reflexed by means of the bass-reflex enclosure, it is possible to simulate a set-up of an imaginary transducer which is housed in the said bass-reflex enclosure and which...

An ink jet print head for projecting droplets of ink on demand includes a pressurization chamber including at least one wall defining a vibratory plate. A nozzle is open to the pressurization chamber and defines a fluid passage through which ink is ejected. A piezoelectric element is operatively coupled to the vibratory plate which is selectively energized to vibrate the wall thereby changing the ...

Printing machine with at least one printing unit having rotating cylinders, comprising an energy converter disposed at least partially in one of the cylinders for converting at least some rotational energy of the cylinder into electrical energy and an energy storage device also disposed in the cylinder for storing the electrical energy.

Control circuit for setting various spinning speeds of a washing machine, in which an electrical contact of an electromagnetic programmer controls spinning and an adjustment circuit for the motor of the washing drum sets various spinning speeds for different input and datum values, characterised in that an electrical contact 1 is provided solely to control the spinning, in that the electrical cont...

An apparatus provides a user-adjustable viewing angle for a cathode ray tube (CRT) display. The CRT may be rotated in either of two directions by depressing a control bar located along the front bezel of the display. Once set to the desired position, the control bar is released and the CRT is inhibited from rotating in both directions. Thus, the CRT may be locked in a variety of positions to suit ...

A full bobbin supply and an empty bobbin ejecting device for an automatic winder disposed between a full bobbin feeding conveyor and an empty bobbin ejecting conveyor. A full bobbin doffed from a spinning frame is fitted on a peg erected on a bobbin carrier and conveyed. The bobbin carrier with the bobbin is stopped at the stand-by position by a first stopper, and then supplied to a yarn running p...
