Abstract: Removal of dust and SO2 from hot waste gases (I) with low H halide conent and reheating of purified (I) involves : (a) cooling (I) to under 135 deg. C in a H2SO4 scrubber; (b) sepg. H2SO4 contg. solids and dissolved metal sulphates from (I); (c) cooling (I) to 50-70 deg. C by scrubbing with 15-50% H2SO4; (d) desulphurisation, with H2SO4 formation; (e) heating to 50-90 deg. C again by scrubbing with 50-65% H2SO4, with simultaneous concn. o the acid from stage (c); and (f) cooling the H2SO4 contg. solids from (a) by heat exchange with the pure H2SO4 from (e). 70-80% H2SO4 contg. solids and metal sulphates is used in (a) and the solids deposited in (a) are sepd. from a side stream of 0.2-10, pref. 1-5% of the circulating acid. A droplet separator is used in stage (b), pref. a lamellar droplet separator, esp. of PVDF. H2SO4 is formed in stage (d) by adding H2O2 and/or peroxysulphuric acid to scrubbing in (c); or by catalytic reaction on moist activated charcoal, the H2SO4 formed being removed with water at 2-20% soln. and passed to stage (c). The pure H2SO4 formed in (d) is discharged from the system as 50-65% pure H2SO4.

Abstract: The diaphragm pump has a first chamber for the fluid to be pumped with inlet and outlet valves, and a second one for the driving fluid, separated from the first by the diaphragm. A reciprocating plunger alternately pressurises and releases the driving fluid, for which a storage chamber is provided.  This is connected to the second chamber by a return pipe with safety valve, and also by a make-up pipe with valve. To measure the deflection of the diaphragm (4) where the driving fluid acts against it (22,23) a signal emitter (31) is mounted in it, working with a receiver (32) in the housing (2,3) and preferably at the same level.  The signals from both are evaluated and monitored outside the pump (1).  The signal emitter (31) comprises permanent magnets arranged in or on the diaphragm (4).  The signal receiver (32) is a  magneto-resistive sensor.

Abstract: Immunological reagents, consisting of a) antibody or fragment conjugates having both an anti-cell specificity and an anti-hapten specificity, and b) synthetic tracers containing at least two hapten sites and at least one site suitable to attach radioactive isotopes, paramagnetic ions, drugs, or toxins, are provided. These reagents are capable of binding to target cells in a specific way, and the tracer localizes preferentially on the membrane of antigen-bearing cells, even in the presence of excess antibody conjugate (affinity enhancement). These reagents are usefully employed, either in vitro or in vivo, to detect tumors, metastases, or other tissue injuries, when the synthetic tracer carries radioactive or paramagnetic compounds, and to kill target cells when the synthetic tracer carries radioactive compounds or drugs or toxins.

Abstract: A technique for generating isotherms representing the cross-sectional temperature profiles of molten glass (17) flowing in a forehearth channel (20). A plurality of temperature sensors (21-29) are placed at predetermined locations within the plane of the channel cross-section, advantageously in a rectangular grid, to provide a matrix of temperature readings. Digitalized temperature readings from these sensors are routed to a processor (53). which interpolates these temperature readings to approximate the temperature intermediate the various sensing points, and optionally beyond the array of sensing points. The isotherms are obtained by fitting a Legrangian interpolating polynomial through the various recorded temperatures. The interpolated values thus generated may be used to provide real time displays of isotherms in the forehearth cross-section under examination, or may be included in a control loop.

Abstract: Because of the size of the devices for the excitation or measurement of light, conventional sensor elements for optical determination of the concentration of substances in gaseous and liquid probes, which have an indicator layer with at least one indicator substance are only conditionally suitable for microanalysis instruments, or cannot be produced simply by mass production. To circumvent these disadvantages, it is proposed that at least one photosensitive element (3) and its electrical contact are integrated in a planar arrangement on the carrier layer (1), and that the indicator substance (7, 7') of the indicator layer (6), which is excited by the exciting radiation (11) is in optical contact with the photosensitive elements (3).

Abstract: Clamping cylinder 22 slidably receives a clamping ram 26 whose front end is fixed on a movable board 20 of (e.g.) an injection molding machine (21,23-25) and which has a chamber opening in its rear face. The interior of the clamping cylinder 22 is divided into a rear chamber W and a front chamber X by the large-diameter piston section of the clamping ram 26. From the inner rear wall of the clamping cylinder 22 there projects, a mold opening piston having a front end which slidably fits in the chamber in the clamping ram 26. The opening piston has a large-diameter piston section which divides the chamber into a rear chamber Y and a front chamber Z which communicates with the atmosphere. A hydraulic controlling device 31-37 controls the connection of the chambers X,Y and Z to each other and to an oil pressure source 40. Thus it connects the chambers X and Y to the chamber W for high-speed mold closure. It connects the chamber W to the oil pressure source 40 and relieves the pressure in the chambers X and Y for tight clamping; and it connects the chamber Y to the oil pressure source and connects the chamber W to both the chamber X and the relief means 32 for opening the mold. Preferably, the effective pressure receiving area of the chamber Y is to be equal to the cross-sectional area of the chamber section of the clamping ram 26.

Abstract: The zero voltage DC to AC inverter includes a transformer with two MOSFET switches in two paths and using parasitic capacitance to form a resonant circuit with the transformer inductance. Drive signals from a signal generator control the two switches giving approximately symmetrical path switching and also ensuring that the transformer is not loaded during the time when neither of the synchronised switching paths are conducting. Rectification units may be added, obtaining a DC output when the inertial current may be directed to a capacitance instead of the transformer secondary via the rectifiers so ensuring the transformer is not loaded during dead time.
