    • The invention concerns a insert for filling the dental canal comprising means for anatomically and physiologically filling up the root canal (1), comprising a ductile and resilient core (10) made of a polymerised composite material, sheathed in one or several sleeves (14, 15) made of a composite material pre-impregnated with resin, being in a first pasty state previous to polymerisation so as to make the insert flexible and malleable before and during its introduction into the root canal (1). Said material is then capable of being polymerised at will by cross-linking means to be in a second polymerised state after the insert has been introduced in said canal. The upper part (17) of the insert which emerges from the root canal (1), can advantageously be used as prop or pivot for a coronal reconstitution. Thus, the same material is used for filling the root canal and for reinforcing the residual structures of the tooth. The canal obturator and the anchoring pivot are made of one and the same material.
    • 本发明涉及一种用于填充牙槽的插入物,包括用于解剖和生理填充根管(1)的装置,所述装置包括由聚合的复合材料制成的延性和弹性芯(10),所述聚合复合材料被包覆在一个或多个套筒 15),其由预先浸渍有树脂的复合材料制成,在聚合之前处于第一糊状状态,以使得插入件在引入根管(1)之前和期间使其柔性和可延展。 然后所述材料能够在插入物被引入所述管道之后通过交联手段随意聚合成第二聚合状态。 从根管(1)出来的插入物的上部(17)可以有利地用作冠状重建的支柱或枢轴。 因此,使用相同的材​​料填充根管并加强牙齿的残余结构。 运河填塞器和锚固枢轴由同一材料制成。

    • The heating device for a machine for transforming plastic materials, comprises a heating body (39) disposed between two parallel rows (41, 42) of preforms (14). It is provided with at least two heating tubes (40) having bidirectional heating blades (54). These latter are inclined at an angle ( alpha ) such that a first of their faces emits heating radiation (55) in the direction of the adjacent row of preforms and such that the second surface emits its heating radiation (56) substantially in the direction of the free space between the two opposite rows of heating tubes toward the farthest row of preforms. Reflectors (60) are moreover arranged so as to reflect the heating radiation in a horizontal plane toward the preforms (14). The device thus permits obtaining very high energy efficiency whilst avoiding a harmful elevation of the temperature of the machine into which it is integrated.
    • 用于转换塑料材料的机器的加热装置包括设置在预成型件(14)的两个平行列(41,42)之间的加热体(39)。 设置有至少两个具有双向加热刀片(54)的加热管(40)。 这些后者以一定角度(α)倾斜,使得它们的第一面在相邻行预成型件的方向上发射加热辐射(55),并且使得第二表面基本上沿着预成型件的方向发射其加热辐射(56) 两排相对的加热管之间的自由空间朝向最前排的预成型件。 此外,反射器(60)布置成将水平面中的加热辐射反射向预成型件(14)。 因此,该装置允许获得非常高的能量效率,同时避免其被集成到其中的机器的温度的有害提升。

    • The machine for the production of receptacles of plastic material comprises a loading device (5) in which the preforms (2) are disposed neck down on supports (7) of double carriers (8) heated in a heating device (10) and moved into a drawing-blowing device (12). In this latter, the receptacles are formed and then discharged into a discharging device (14). In the part (21) of the guide track (20) the supports (7) and the preforms are aligned in a single row, whilst in the part (22) the supports (7) and the preforms are arranged in a plurality of parallel rows. Between each row of preforms of a row of carriers (8), the heating device (10) comprises a heating body (42) arranged so as to heat bidirectionally the preforms located on each side of the heating body (42). The heating device can moreover be raised from an active position to an inactive position and vice versa. There is thus obtained a machine with a very high output, of reduced size and low consumption of energy.
    • 用于生产塑料材料容器的机器包括装载装置(5),预成型件(2)在其中颈部向下设置在加热装置(10)中加热的双载体(8)的支撑件(7)上,并移入 抽吸装置(12)。 在后者中,形成容器,然后将其排出到排出装置(14)中。 在导轨(20)的部分(21)中,支撑件(7)和预成型件以单列对准,而在部件(22)中,支撑件(7)和预成型件被布置成多个平行 行。 在一列载体(8)的每排预成型件之间,加热装置(10)包括加热体(42),其被布置成双向地加热位于加热体(42)的每一侧上的预成型件。 此外,加热装置可以从活动位置升高到非活动位置,反之亦然。 因此获得了具有非常高的输出,尺寸减小和能量消耗低的机器。
