A compact laser head for a solid state laser has a miniaturized laser rod and output coupling mirror which form a miniaturized laser cavity. A miniaturized frequency doubler crystal placed in the cavity provides frequency doubled output. The laser head is connected by an optical fiber to a separate power suply which contains a laser diode pumping source. A quick disconnect connector enables the fi...

A device for irrigating the intestines that can be employed during surgery with an irrigating cannula for introducing a rinse and with a drain. To ensure irrigation during surgery of a section of intestine of any diameter upstream of the stenosis while avoiding any contamination of the operating field, the drain consists of an adapter connected germ-proof to a hose and of a plastic fastener securi...

In an accumulation conveyor comprising load-carrying rollers, a roller drive is so devised that all rollers under one and the same load at a time are either being positively driven by, or are disengaged from, the said drive. Mechanism controlling engagement of the drive comprises a combination of a clutch-actuating linkage and a priming linkage which prepares the actuating linkage for operation. T...

A refractory material which contains iron is characterised in that it includes an additive which acts as an iron catalyst poison. e.g. elemental sulphur or a sulphur containing compound such as potassium sulphide or an organic sulphur containing compound which leads to the formation of iron sulphide, and good CO resistance.

A process of forming a coherent refractory mass on a surface comprises projecting against that surface, together with oxygen, a mixture of refractory particles and fuel which reacts in an exothermic manner with the projected oxygen to release sufficient heat to melt at least the surfaces of the refractory particles and thus form the refractory mass. The projected mixture contains, as fuel, finely ...

A pillow, or the like, has a stuffing comprising substantially spherical wood particles adapted to release a contained fragrance. The wood particles may have a natural fragrance or a fragrant essence may be added. The stuffing may be made by cutting wood into cubic chips and forming the chips into spherical particles, which may have roughened surfaces, by treatment in a sandpaper grinding machine.

An acidic liquid detergent composition for cleaning ceramic tiles without eroding the grout between the tiles comprises minor proportions of partially neutralized glutaric acid, partially neutralized phosphoric acid, surface active condensation product of ethylene oxide and higher linear alcohol of 10 to 20 carbon atoms, such as the condensation product of a linear secondary alcohol averaging abou...

A filter material is a felt of 60 weight % 2.8 decitex polypropylene fibres and 40 weight % of 3.5 decitex modacrylic fibres.

Emergency escape platform apparatus including an escape platform disposed in spaced apart relation from a drilling platform and joined to the drilling platform by escape bridge apparatus. Two flexible base cables are connected in tension horizontally adjacent between the escape platform and the drilling platform. Two flexible hand cables are connected in tension horizontally adjacent to one anothe...

A golf club (10) is described, the golf club having a grip (20) with a weighted element integrally attached to the distal end. The weighted element is fixedly secured within the grip and is shaped in the form of an inverted cup, with flanges (53) depending from a central spherical portion. The grip itself is of a resilient material and completely encloses the weighted element, including both sides...

PURPOSE:To adhere optical fibers with a high reliability by using optical fibers where metallic coatings are provided on outside peripheral parts and splicing optical fibers mutually or the optical fiber and an apparatus or an element. CONSTITUTION:In case of mutual splicing of optical fibers by soldering, a proper jig is used to put a solder 6 on butted end parts where sheaths are removed to expo...

PURPOSE:To simplify the work to connect optical fibers with a high reliability by using optical fibers where metallic coatings are provided on outside peripheral parts of clads and using this jig to connect optical fibers mutually by soldering. CONSTITUTION:The jig consists of a metallic chip C having a V groove 21, on which optical fiber terminal parts which have metallic coatings exposed are but...

A divisible capsule for highly viscous, pulverulent, granulated or tablet-shaped drug formulations and process for the preparation thereof.

A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the unit(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the...

The point at which pump out pressure exceeds load is sensed to provide a point for scheduling flow to an actuator in a hydraulic system, such as an elevator. Flow is controlled by a stepper motor (28) that moves a flow control valve (27). When the pump (21) is turned on, the valve (27) is positioned to bypass flow; the bypass flow is then programmably decreased to increase the flow to the actuator...
