The autofocus microscope has an objective lens (10) which is positioned by a motor (27) between the object surface (16) and a beam splitter (20), above which a tube lens (12) and another beam splitter (69) underlie the image plane (14). A pattern imaging system forms a pattern (64) through the objective lens along the main beam path (8). The image of this pattern is combined (68) with that of the ...

A basic material for the clothing and shoe industries is permeable to water vapour, but resists the passage of water and comprises a layer of a flat knitted textile material (3) and a layer of a thermoplastic melt blown fleece (2) based on microfibres with a weight of 10-100 g/<2>m, preferably 20-70 g/m<2>. The layers (2,3) are laminated to each other using heat and pressure which plasticises the...

The connector clamp for wiring up bus device inputs has two spring clamp connectors (6) per pole for clamping to the bus bar, and a plug connector (3) per pole of the socket part (11, 12). The clamp connectors (6) are arranged in parallel and are formed from a plugged in contact insert member. The axial plugging in direction of the sockets (11, 12) extends in the connection direction of the clamp ...

A hydrophobic bonded antistatic material with increased surface conductivity is made by hot embossing of a laminate of layers of a non-woven fabric layer of fibres or endless molecularly oriented filaments of thermoplastic polymer with an inner layer of melt-blown microfibres of thermoplastic polymer with a fibre diameter of below 12 microns. The agent for raising the surface conductivity of the m...

Preparation of a monolithium acetylide/ammonia complex by the reaction of lithium amide and acetylene in ammonia, by carrying out the reaction at a temperature of from -10 DEG to 30 DEG C.

The marking element (1), which is made of a magnetisable material, consists of a central section (2) and at least one lateral section (3) in one end region of the central section. It emits a characteristic signal when subjected to an alternating magnetic field. The signal is detectable using a monitoring device. A means (4) of deactivating the marking element is arranged near the central section. ...

The electronic monitoring and alarm system is used to provide protection against the theft of articles. The system has a voltage controlled oscillator (2) that connects with a power amplifier (3) that outputs a signal to a transmitter (4) to create an electromagnetic field. The field produced interacts with a security hanger element (5) attached to the article that forms part of a resonator circui...

An electronic security system to prevent theft of articles uses a hanger (9), to which the article is attached, that is located within an electromagnetic field. The hanger contains an inductance and capacitance coupled as a resonator device and is located between transmitting (8) and receiving (10) aerials. A voltage controlled oscillator (2) is controlled to produce a range of frequencies that ar...

The present invention provides a signal loss recovery device (300; 400; 900) and method (500; 600; 1000; 1100; 1200) of digitally encoded bitstreams produced by predictive encoders, for realtime and/or interactive communications. The signal loss recovery device (300; 400; 900) of this invention recovers the lost or damaged information by requesting the transmitter for retransmitting the lost infor...

A refrigerator oil composition prepared by blending a base oil comprising a mineral or synthetic oil with at least one member selected from the group consisting of metal salts of inorganic phosphoric acid (e.g. potassium phosphate), amine salts of inorganic phosphoric acid (e.g. octylamine salt of phosphoric acid), metal salts of organic phosphoric acid (e.g. dipotassium lauryl phosphate), amine s...

A bone anchor and a bone anchor installation tool for deploying the bone anchor in bone.

An inventory of goods is protected from theft by means of electronic article surveillance (EAS) markers integrated with items of the inventory. Each such item has a structural member in which a cavity is integrally formed. A respective magnetostrictive element is housed, free of mechanically clamping constraint, in each cavity. A respective biasing element is located adjacent to the cavity on each...

An acoustical tile composition based on a gypsum/cellulosic fiber composition which can replace all or a portion of the mineral wool normally present in acoustical ceiling tiles. The gypsum/cellulosic fiber composition is combined with a lightweight aggregate material and a binder to form a composition which is used in a water-felting process to manufacture acoustical ceiling tiles and panels. The...
