Abstract: In a self-cleaning filter assembly (10), a filter element (31) is fixed within a housing (17) and spaced from the peripheral wall (21) thereof by an annular solids collection space (34) in turn communicating with a solids outlet (63). An inlet (56) introduces pressurized liquid to be filtered circumferentially into the solids collection space. A shower assembly (81) rotates and includes an eccentric portion (84) having jets (91) aimed outward close to the inner surface of the filter element. Backwash liquid enters the rotating shower assembly under pressure for continuously pushing solids off the outer surface of the filter element as the shower assembly circumferentially advances. Filtrate from inside the filter element passes through a filtrate outletfromthe housing. A solids outletvalve (163) responds to a preselected increase in liquid pressure differential between the inlet and filtrate outlet to increase , venting of the annular solids collection space. A filtrate outlet valve (181) may simultaneously close to direct all liquid flow out the solids outlet. 1

Abstract: Discarded rubber tires are charged in random state into a vertical dry distillation furnace (1), and the tires at a lower part thereof are caused to undergo combustion to give off hot combustion gases by which the tires at higher levels undergo dry distillation to produce distillation gases which are useable as fuel. The combustion is started by burners (9) and is then self-sustained by supplying only air. The furnace Interior at its part (3a) below the combustion zone is expanded or flared in the downward direction to an open end immersed in water, but the downward movement of the tires and residue is braked by a self-sustained grate effect until the residue finally drops out of the furnace to be removed by a conveyor (14). The continuous and efficient operation over a long period of this furnace is assisted by a separator (2) also capable of long continuous operation.

Abstract: The glass shaping machine has the rotatable drive mounted on an ejector (97) which pushes the shaped glassware (101) from a deadplate (102) onto a conveyor belt (122). It is proposed that the rotation movement be carried out with the aid of a rotary drive (59) which can be actuated hydraulically. In a preferred embodiment, the rotary drive (59) is preceded by two containers (60, 61) which contain hydraulic fluid (62) and on which compressed air can impinge. The compressed air is controlled by two valves (74, 75). The first valve (74) can be controlled from a central control unit, while the other valve (78) is actuated mechanically by a position sensor (112, 113) which indicates the position of the rotary drive (59). A flow control valve (65) in a hydraulic fluid line from the rotary drive (59) to one of the containers (60, 61) allows the rotary speed to be adjusted. Overall, the use of the hydraulically operated rotary drive (59) provides a substantially heat-insensitive, robust rotatable drive which is versatile, ensures quiet and smooth rotary movement by avoiding joints and frictional or mechanical clutches, does not need constant monitoring in a glass shaping machine having a plurality of stations, is simple to adjust, and, in the embodiment shown, is simple to install and exchange. <IMAGE>

Abstract: In these pneumatic tyres which are constructed as radial tyres, the part of the contact strip zone located above the belt is of two- layered construction. An upper layer having the tread is provided above a base layer. In order to exclude damage due to elevated temperature effects and thus obtain high speed resistance and also to avoid formation of fractures in the profile base, a synthetic rubber with a dynamic E module of approximately 6 to 15 N/mm<2> and a dynamic loss module of approximately 1.5 to 4.0 N/mm<2> is used for the base layer facing the belt. The base layer designed in this way should receive a hardness which is greater than that of the upper layer, that is to say be harder by approximately 10 to 15 Shore Grade A. In particular, the grip in wet conditions of the base layer should be greater than the grip in wet conditions of the upper layer. The differences should be approximately 4 to 7%. The dividing face between the upper layer and the base layer can also be arranged above the profile base. <IMAGE>

Abstract: In manufacture of composite steel ingot, a consumed electrode 11 is inserted into an empty space concentric with the ingot 10, and electroslag remelting is effected under a slag bath 16 and the molten metal solidifies. Current is taken out through a plurality of collecting electrodes 12 electrically connected to the ingot. To obtain improvement in the uniformity of depth of fusion of the ingot, the flow path of the electric current passing from the consumed electrode to the collecting electrodes is moved in the circumferential direction of the ingot during the electroslag remelting, e.g. by rotating either or both of the ingot and the collecting electrodes. Further improvement may be achieved by varying the speed of movement of this flow path as the slag bath ascends the ingot.

Abstract: From a spring band (6), a first winding (18) is formed which is comprised of turns which are arranged flat on top of each other. A straight terminal portion (6A) not yet wound of the spring band is folded in the direction opposite to the flexure direction of the winding turns (18), in an arc of a circle to form a terminal arc (6B) directly connected by a continuous and progressive junction to the outer turn of the winding (18). The curvature radius of the terminal arc (6B) coincides with the radius of a winding mandrel (19) on which is wound the spring band (6) after having been subjected to a heat treatment, and in the direction opposite to the flexure direction of the turns of the first winding (18). The thus formed second winding (20) is provided to be inserted as a driving spring into a spring casing, the end (7) of the spring band (6) situated outside on the second winding (20) being connected to the circumferential wall of the spring casing and the terminal arc (6B) now arranged inside being connected to a core rotating in the spring casing and of which the radius coincides also with the curvature radius of the terminal arc (6B). The spring core may be coupled to a winder drum, for example for a safety belt. The driving spring thus obtained is differentiated by a proportionally high initial torsion moment, as soon as a small member of revolutions of the spring core is reached.
