Title: Monitoring chemical reactions photoelectrically
IPC: G01N21/25
Filed: 1978-06-19
Abstract: An array of cuvettes 32 on a turntable 74 is advanced continuously or preferably intermittently along a circular path. Photometer means, preferably having several photometric detectors 52, are mounted on a rotor 56 that advances rapidly compared with the movement of the cuvettes so that each cuvette is monitored many times by a specific photometric detector during each rotation of the turntable. The photometric detectors 52 can operate at several different wavelengths. Many different chemical reactions can be monitored at the same time. Detector signals are converted into digital signals and transmitted from the rotor 56 to a stationary receiver, e.g. as a pulsed train of light signals or by slip rings 110-116. A motor 128 may drive the turntable through stations for automatically dispensing samples and reagents into the cuvettes and for cleaning the cuvettes. Each photodetector may have a separate light source (fig 3, not shown), and the light from the source may be split and pass as two beams through each cuvette at different levels to separate detectors (fig 4, not shown). <IMAGE>

Title: Hydraulically damped elastomeric mounting
Inventor: HEITZIG JURGEN
IPC: F16F13/12
Filed: 1983-08-26
Abstract: Elastic engine mountings having a ring-shaped rubber spring member 3 which takes up static and dynamic loads and being equipped with a damping disc 8 immersed in a damping fluid 6 in order to provide hydraulic damping have been proposed. In accordance with the invention, the damping disc 8 is movably mounted with axial play between spherical or ball-shaped buffer surfaces on a rod 4 and is provided with holes (81) through which the damping fluid can flow in the vicinity of the buffer surfaces. Low amplitude movements of the rod are not transmitted to the disc 8 and are therefore undamped. Larger amplitude movements are transmitted to the disc 8, but impact noise is minimised by the buffer surfaces and the flow resistance afforded by the holes (81). <IMAGE>

Title: Rotary fluid-machine
Inventor: STANGROOM DR JAMES EDWARD
IPC: F04C7/00
Filed: 1983-11-30
Abstract: In a pump for an electro- rheological fluid a fluid-transfer path 38 is provided between movable electrically-conducting surfaces 18, 36 of e.g. a driven metal rotor 6 and a metal belt 34, the ends of said path communicating with inlet and outlet ports 42, 44 for said fluid, which ports may be shielded from each other by a fixed partition, or "wiper", 40. When an adequate electrical potential- difference is applied to the surfaces 18, 36 the fluid in the path 38 becomes a flexible solid and so travels with the belt towards the outlet port, whereat it resumes its normal fluid state. Other embodiments are described with reference to Figures 3 to 6. The machine may be employed as a motor instead of a pump. <IMAGE>

Title: Process of forming a refractory mass and lance for spraying particulate exothermically oxidisable material
Inventor: PLUMAT ROBERT
IPC: F27D1/16
Filed: 1985-01-26
Abstract: In processes of forming a refractory mass on a working surface, a mixture of exothermically oxidisable particles and refractory particles in a comburent gas are sprayed against that surface by conveying them along a lance to a lance head and discharging the mixture under conditions such that the oxidisable particles burn and melt at least the surfaces of the refractory particles to form the refractory mass. To promote the reliable achievement of a durable refractory deposit, especially at high material build up rates, mixed exothermically oxidisable and refractory particles are sprayed in a comburent gas from a lance 1 having a group of nozzle outlets 28, at a discharge rate in excess of 50kg per hour per square centimetre of aggregate nozzle outlet area. The group of nozzle outlets 28 are so spaced and arranged that, when the nozzle outlets 28 are viewed end on, each of them is spaced from a first other nozzle outlet 28 of said group by a distance S1 which is not more than three times the smallest diameter of its own cross section or that of that first other outlet, and is spaced from a second other outlet of said group by a distance S2 which is not more than eight times the smallest diameter of its own cross section or that of that second other outlet, and so that the centres of at least some of the nozzle outlets of said group define apices of a notional polygon 23. <IMAGE>
