Abstract: PCT No. PCT/EP90/00456 Sec. 371 Date Sep. 26, 1991 Sec. 102(e) Date Sep. 26, 1991 PCT Filed Mar. 20, 1990 PCT Pub. No. WO90/12184 PCT Pub. Date Oct. 18, 1990.A device is provided for opening and closing a door (5) in a doorway (7) of a structure (9) in a railway or bus car comprising an upper ejection assembly, a lower ejection assembly and a translation assembly, the upper ejection assembly further comprising a translation slide bar. The upper and lower ejection assemblies comprise rotation arms (1, 11) joined at one side to the fixed structure (9) by hinges (13) mounted through curved slots on respective brackets (15), and at the other side to a frame which is integral with the door (5). A slide bar (37) passes through the doorway (7) and is pivoted at one end to a movable end of the upper arm (1), and at the other end to a fixed bracket (47) on the other side of the doorway (7). After the door (5) has been separated from the doorway (7), the door is translated by means of a suitable rack (61) integral with the door, engaged by a gear wheel (59) which is driven through suitable gears (55, 57) by another rack (53) which in turn is driven by a rod (51) of a fluid actuated cylinder (49). According to one embodiment of the invention, the ejection assemblies are driven by at least one fluid pressure cylinder (20) the rod of which is secured to a rack (19) which engages a suitable gear wheel (21) keyed on a rotation shaft (23) of the ejection arms (1, 11) and causes their partial rotation, thus accomplishing the separation or ejection of the door (5) from the doorway (7) of the structure (9).

Abstract: This invention relates to a profile control device that performs profile machining of a work copying a model surface. A profile control device (1) includes a profile control circuit (13), a digitizing circuit (16), and numerical control circuits (11, 18x, 18y, 18z). The profile control circuit (13) controls multiple profiling shafts (40x, 40y, 40z) to copy a model surface (43). The digitizing circuit (16) connected with the profile control circuit (13) via a bus acquires the positions of the multiple profiling shafts (40x, 40y, 40z) from one minute to the next as position data, and also performs the prescribed data processing to prevent the intrusion phenomenon and generates NC data that are linearly approximated to the model surface (43). The numerical control circuits (11, 18x, 18y, 18z) are connected with the digitizing circuit (16) via the bus (10), and control the positions of as many machining shafts (60x, 60y, 60z) as the number of the multiple profiling shafts (40x, 40y, 40z) based on the NC data and perform the machining of a work (63).

Abstract: The invention relates to pourable, fine-particle dry powders based on a water-soluble and/or water-distendable combination of non-ionogenic cellulose ethers and dried redispersion polymers mixed, if desired, with other additives with and/or without adhesive force. The new dry powders are characterized by a particle structure with the closed nuclei of the non-ionogenic cellulose ethers surrounded by a sheath for the redispersion polymers to which they firmly adhere. In another embodiment, the invention relates to a method for producing these new pourable dry powders, characterized in that the non-ionogenic cellulose ethers in powder form are mixed with the aqueous polymer dispersion and the temperature of the aqueous phase is maintained at least at the cloudiness or flocculation point of the non-ionogenic cellulose ether or above. Under these conditions, the aqueous mixture of substances is spray-dried. The new composite materials are suitable for a wide range of applications as adhesives and/or binders with improved properties.

Abstract: A ratchet tensioning device for the step-by-step tensioning and releasing of clamping belts, having a console (1), a clamping lever (2), a winding-on shaft (4), which supports a ratchet wheel (3, 3'), and two ratchets. The ratchet wheel (3, 3') is the common locking piece for the two ratchets. The drive ratchet, which acts between the clamping lever (2) and the winding-on shaft (4), is used for the rotating drive of the winding-on shaft (4). The ratchet which protects against turning backwards and acts between the console (1) and the winding-on shaft (4) protects the winding-on shaft (4) against turning backwards. The ratchet which protects against turning backwards consists of the ratchet wheel (3, 3') and of two separate locking slides (5, 5'). The locking slides (5, 5') can be pushed back out of the tooth system (33) alternately by means of an unlocking cam (37) which is integrally formed on the clamping lever (2), as a result of which the ratchet can be unlocked in a step-by-step manner.

Abstract: The bottle neck (1) of the vacuum drainage bottle is provided at its mouth with a flange (2) which has a flat end face (3). An outer annular rib (4) concentric to the axis of the bottle neck forms an undercut shoulder (5). The flange (2) and the annular rib (4) have at least approximately the same external diameter, which is greater than the external diameter of the bottle neck (1) between the flange (2) and the annular rib (4). The flat end face (3) of the flange (2) forms a sealing face with the inner surface of a wall (10) of a pot-shaped stopper (8) made of an elastic rubber material. An inner projection (11) of the stopper (8) engages behind the shoulder (5) of the annular rib (4). During the sterilisation process of the drainage bottle, the air or the vapour can escape quickly via the intermediate space (13) between the bottle neck (1) and the jacket (9) of the stopper (8).

Abstract: 2.1 It is known in the case of a commercially available magnetic tape device having a head drum which can be driven by a motor to heat the head drum by means of a heating element in order to prevent moisture forming on the head drum. For this purpose, the heating element is arranged on the fixed lower part of the head drum by means of a metal clip. The energy supply to the heating element takes place via a connecting cable and an electronic switch from a voltage source located in the power supply unit of the device. The object is to reduce the relatively great expenditure for heating the head drum. 2.2 The heating element (61) is arranged in the stator (95) of the motor (M), forming a mechanical unit with the head drum (90), in such a way that additional fastening means are not required for the heating element (61). Heat generated with the aid of the heating element (61) is directed at the head drum (90) via the stator assembly (95b), comprising iron sheets, and a spindle housing (93a) for the motor shaft (99), which housing is formed in the lower part (93) of the head drum and extends into the motor space. A further reduction in the expenditure is achieved by the motor operating voltage (UB2) being utilised for the energy supply of the heating element (61) and by the electronic switch (60; 70), by which the heating element (61) is switched, being controlled by means of the motor control circuit. 2.3 In particular a head drum for a video recorder. <IMAGE>
