Abstract: SPEAKER CROSSOVER NETWORKS           ABSTRACT OF THE DISCLOSURE The invention comprises improved electroacoustic audio speaker cross-over networks. The improvements comprise both the addition of various passive elements and a novel inductively coupled circuit configuration. The improvements are applied to low pass and nigh pass networks and combinations thereof. In the preferred embodiments a separate electrical circuit is inductively coupled to the filter network. The physical configuration of the separate circuit can be easily adjusted to counter variations in individual speaker performance parameters Thus, production variations in speakers from the same manufacturer or among the products of different manufacturers can be overcome and a better matching of speakers provided. In the simplest embodiment the separate inductively coupled circuit comprises a copper ring placed within an inductive coil of the filter. Adjust-ment is accomplished by adjusting the physical location within the coil or by small changes in the physical dimensions of the ring.

Abstract: Abstract A collecting rope which is intended especially for collecting oil from the surface of water, the rope comprising a drive chain (9) which is situated inside a cylindrical part (3), which is surrounded by a lightweight float layer (5), which is surrounded by another cylindrical part (1), oil-collecting bristles (6) being attached to the outer surface of the outer cylinder. The cylindrical parts can rotate in relation to the drive chain (9), since the joint between them consists of resilient protrusions (11) on the inner surface of the inner cylinder (3). The cylinders and the chain are, however, locked to each other in the longitudinal direction.

Abstract: ABSTRACT     A sintered, honeycomb structure having plugged cell ends is formed in a single sintering step by plugging the cell ends of a sinterable honeycomb structure with an appropriate material which,  when heated to the  sintering  temperature  of the structure and  compared with any dimensional changes  the structure undergoes  during  its  sintering,  provides  a  rela-tive expansion of the plugs with respect to the structure of between about 1.5% and 7% and, preferably, between about 2 and 4%.  Various exemplary batch mixtures are identified for fabri-cating solid particulate filter bodies from extruded  ceramic substrates in  which  both  the  substrate  and plugs  sinter to primarily cordierite  crystal  phases  at  temperatures  between about 1340°C. and 1450°C.

SAWYER OVERHEAD CORROSION SIMULATOR                 Abstract of the Disclosure Apparatus for determining the corrosion rate of petroleum distillation equipment so that corrosion inhibi-tors may be effectively utilized to control corrosion.  The apparatus includes a water box having a coil arranged in the box through which hydrocarbon vapors are directed.          Cooling water is forced through the box in a counterflow direction to cool the vapors and simulate cooling that will take place in heat exchange units.  Corrosion and tempera-ture probes are arranged along the coil to determine cor-rosion rates at the various temperature levels of the hydrocarbons so that a corrosion profile can be established and related to the temperature of the vapors at various locations in the heat exchange units of the equipment.

Abstract: ABSTRACT     An electrical apparatus useful to prepare a hot beverage from a flavour substance.The apparatus has a flow-through heater, a container for a liquid and a cup unit for the flavour substance. A pipe joins the cup unit and the liquid container. The cup unit includes a cup and there is a filter carrier to fit in the top of the cup and to carry a filter containing the flavour substance. A passage extends through the filter carrier and is open at both ends of the carrier. A channel is formed between the base of the filter carrier and the passage. Further passages join the interior of the passage to the channel. The filter carrier has upper and lower closures. The heater unit has a container for a liquid; a heater for the liquid and a head to fit over the cup unit. The pipe extends from the heater to the head. The apparatus allows the liquid to pass from the container through the pipe through the head, into the filter and through the upper closure of the cup unit so that liquid may pass through the flavour substance in the filter to form the beverage.

Abstract: ABSTRACT OF THE DISCLOSURE        To control the amount and the loss of pressure in several pneumatic conveyance paths in parallel, a pressure measurement point is determined, situated at a position such that the loss of pressure .DELTA. P between that point and the point of injection of the pulverulent material into the vessel will be the same for all the pipes and for the same charge of material in the pneumatic current, it is determined by theoretical and experimental methods what must be the values of these losses of pressure between these 2 points for a determined amount of pulverulent material, and for different pressures inside the vessel, these values are memorised in the form of calibration curves, during the injection the losses of pressure between the previously determined points are continuously monitored for each of the pipes and the rhythm of the metering means is controlled in such a way that when fluctuations of pressure occur in the vessel the variations of losses of pressure caused by the said fluctuations between the predetermined points are compenstated by an increase or decrease in the quantity of materials introduced by the metering means.

Abstract: ABSTRACT OF THE INVENTION           Higher reaction efficiencies are seen in cellulose etherification reactions when the reagents are continuously added to alkali cellulose at elevated temperatures.  In particular, mixed hydroxyalkylcellu-lose ethers made from a C3 or higher alkylene oxide and an etherifying agent other than an alkyle oxide are prepared at elevated temperatures with higher reaction efficiencies using this process.  In an especially preferred embodiment, hydroxypropylmethyl-cellulose is prepared by continuously adding propylene oxide to heated cellulose containing a small amount of caustic, adding more caustic and then continuously adding chloromethane at elevated temperatures.
