Abstract: Multi-bed fluid bed boiler having at least two fluidizable beds (7, 8), in which boiler ordinary fuel, for example coal, is supplied to the first bed (7), and in which the combustion of this fuel takes place in the first bed (7) and in the following bed (8). According to the invention alternative fuel (13), such as wood chips, waste wood, waste paper, refuse, etc., is adapted to be supplied to the second bed (8) in order to be burnt there. The invention thus provides a simplified fuel supply to the second bed (8) and increased protection of the nozzles (11) for fluid gas from the first bed (7) to the second bed (8) against clogging and the like.

Abstract: This invention relates to an improved manifold system for a multi-cavity injection molding system. The manifold system has one elongated bridging manifold which extends transversely across a number of spaced elongated support manifolds. Each of the support manifolds, in turn, extend across a number of heated probes or nozzles, each of which leads to a gate to a cavity. The bridging manifold has a portion of the hot runner passage extending through it from a single inletto receive melt from the molding machine to a number of spaced outlets. Each of the support manifolds also has an inlet which is in alignment with one of the outlets from the bridging manifold and a number of spaced outlets. Each of the outlets of the support manifolds is in alignment with an inletto one of the probes or nozzles. Each of the manifold has two way junctions at which a larger diameter portion of the hot runner passage joins two smaller diameter downstream portions. In the bridging manifold, the hot runner passage extends along the same plane asthe inlet and outlets, whereas in the support manifold the portion connecting the junctions extends in a transverse plane. Forming the manifold system of separate composite plate bridging and support manifolds with different melt passage orientations improves streamlined and uniform flow and reduces pressure drop while allowing flexibility of system design for different applications.

Abstract: In a numerical control grinding machine using a grinding wheel made of cubic boron nitride, a computerized numerical controller controls the infeed movement of a wheel head to effect a rough grinding and a first fine grinding on a rotating cylindrical workpiece by the grinding wheel and to halt the first fine grinding in response to a sizing signal from a sizing device which measures the diameter of the workpiece being ground. At the halt of the first fine grinding, the numerical controller advances rest jaws to press the workpiece upon the grinding wheel until sizing signal is issued from the sizing device. Until the number of the workpieces ground after each truing operation reaches a predetermined number, the numerical controller increase the infeed rate of the grinding wheel in each of the rough and first fine grindings toward a desired infeed rate on a step-by-step basis. Further, the numerical controller diminishes a set size which determines the time point to issue the first-mentioned sizing signal from the sizing device, toward a desired set size on a step-by-step basis with the increases in number of the workpiece ground after each truing.

Abstract: A secondary suspension for a rail vehicle truck is arranged between a suspension support connected to the car body of the vehicle and a spring support. It comprises several spring groups, whose spring elements each have a set of coil springs held by an upper and a lower spring plate and a metal-rubber spring element and are individually interchangeable. The spring elements are designed so that replacement of the spring groups can be carried out with the truck installed on the vehicle and without using a pressure stand or a lift. This goal is achieved by the fact that there are at least two diametrically opposed holder claws for spring tension holders on the upper and the lower spring plate of the spring groups, to which the spring tension holders are attached when the spring elements are compressed.

Abstract: In a method and apparatus for removing impurities from a liquid, the liquid containing impurities is supplied to an electrolytic bath at a pressure higher than atmospheric pressure. Electrolysis is performed by applying a voltage to electrodes consisting of a metal which easily dissolves upon electrolysis. The liquid is then exposed to atmospheric pressure, and is treated in a flotation separation tank. Fine bubbles formed during the treatment of the liquid in the flotation separation tank attach to the impurities flocculated in the liquid by electrolysis. The flotation separation of the flocculated impurities is performed very efficiently, and high-purity water can be recovered. The apparatus comprises an electrolytic bath (3) consisting of a pressure vessel, in which electrodes of a metal which easily dissolves upon electrolysis are housed, and a constant current source for applying a voltage to said electrodes so as to obtain a predetermined current density in a liquid contained in said electrolytic bath, wherein impurities in the liquid are caused to flocculate by a hydroxide of the metal.

Abstract: A selective ringing circuit for a telephone line includes a rectifier which is normally connected to the telephone line for rectifying the AC ringing and other signals. The rectified ringIng signals will not activate the ringing circuit of the telephone equipment, because a capacitor in the ringing circuit is charged and will not pass current therethrough in response to the DC signal. The selective ringing circuit includes a switch- selective signal-detecting arrangement by which a predetermined one of the ringing signals is detected and is used as an activation signal, while the other ringing signals are rejected. The activation signal activates an electrical connecting device which, when activated, electrically bypasses the rectifier and directly electrically connects the predetermined selected ringing signal to the telephone equipment. An automatic number identification circuit includes a transistor switch connects a predetermined ground resistance to the telephone line. A shunt resistance automatically shunts a tip or ring dropping resistor to compensate for the unbalanced resistive effects of a biasing circuit for the transistor switch. The rectifier supplies consistent polarity DC signals to the telephone equipment.

Abstract: Vacuum packages consisting of a multi-layer composite film serve in many cases for receiving aroma-sensitive consumer goods, in particular of (ground) roast coffee. The vacuum package consists of a central (coffee) block (10) and fin folds (14) which project on both sides. In the region of said fin folds, a tear-off strip (17) can be mounted below a closure seam (11) for easier opening of the vacuum package. Assigned to said strip is a grip tab (19), formed by punch cuts, in the region of a weld (lateral weld 20) of the composite film. 
<??>In order reliably to guarantee the tightness of the vacuum package in the region of the grip tab (19), the tear-off strip (17) ends with its grip end (18) at a distance from the grip tab (19) or the punch cuts of the latter. By this means, fine channels, arising at the edges of the tear-off strip (17) in the region of the lateral weld (20), are prevented from running into the region of the punch cuts. 
<??>The handling of the vacuum package is considerably improved during opening by a special arrangement of the grip tab (19) at a distance from the lateral edge (21) of said vacuum package.
