Abstract: The invention relates to a disengaging mechanism which comprises an arm (47) integral with a pivoting push rod (48) whose end moves in the slide-groove (52) of a slide (50) placed in the elongations (46) of a plate (44). The slide (50) comprises a window (51) through which the manual operating of the locking part causes or does not cause the unlocking of the locked lock, the change from locked to unlocked being obtained by the rotation of the plate (44) about a fixed axis (43) of the lock. An electrical drive device can ensure the rotation of the plate (44) by the intermediary of a pivoting lever (18). The invention also relates to a motor vehicle door lock comprising this disengaging mechanism. <IMAGE>

Abstract: An air-fuel ratio control device comprising a memory which stores the relationship between the degree of opening of the throttle valve and the absolute pressure in the intake passage, which pressure is produced when the engine is in a cruising state. When a difference between the blunt value of the actual absolute pressure in the intake passage and the absolute pressure stored in the memory exceeds a fixed value, the air-fuel mixture is changed from the mixture for the stoichiometric air-fuel ratio to a lean mixture.

Abstract: The apparatus for sweeping gas through a CO2-laser wave guide concerns a wave guide which is designed thinner than a ceramic hollow guide (3) and which is guided in an outer tube (1), leaving a hollow space (13) between the outer tube and the ceramic hollow guide. The outer tube is provided at the proximal end with a gas connection by means of a connection part (2) receiving a focusing optics element (9). The ceramic hollow guide is guided in the outer tube at least by in each case a proximally and distally arranged bearing part (4, 5) which is in each case supported locally on the inner wall of the outer tube (1). The bearing parts (4, 5) are here designed in such a way that free flow cross-sections remain in the area of the support for sweeping gas to pass through. The flow cross-sections are adapted to the clear inner cross-section of the ceramic hollow guide (3) in such a way that there is a flow of gas passing the ceramic hollow guide (3) both externally and internally, which gas flow on the one hand cools the ceramic hollow guide and on the other hand prevents impurities from penetrating into the distal end of the ceramic hollow guide (3) (Figure 1).

Abstract: An arrangement is described for processing teletext information which makes it possible practically without any delay to reproduce the information pages transmitted by television transmitters on the screen of a television set, the updated state of the reproduced pages being ensured. The arrangement includes a buffer (44) for the data signals corresponding in each case to an information page. Furthermore, it includes a microprocessor (32) which receives the buffered data signals and within the period required for the transmission of an information page stores them in a main memory (24) for all information pages. In dependence upon a page request signal entered by a user a control unit (26) generates a control command for the microprocessor (32) which causes the latter to fetch from the main memory (24) the page requested by the page request signal and supply it to an image processor (42) which generates from the data signals the signals necessary for the reproduction on the screen.

Abstract: In a car (1), a sound output arrangement (5) is installed, the loudspeakers (12, 13) of which arranged in the area of the front seats (2, 3) are connected via a sound amplifier (17) and a delay arrangement (18), the delay of which can be set, and the loudspeakers (14, 15) of which arranged in the area of the rear seats (4) are connected via sound amplifiers (19) with adjustable gain, to the sound signal input (7R, 7L) of a sound reproducing device (6) of the sound output arrangement. The delay arrangements are set to a delay time (3 to 8 ms) at which there is not yet any impairment of the sound impression generated by the loudspeakers for the area of the front seats (2, 3) and the loudspeakers for the area of the rear seats and, on the other hand, the radiation level of the rear loudspeaker groups can be considerably lowered at the associated sound amplifiers (19) without impairing the sound impression in the area of the front seats. <IMAGE>

Abstract: A structural assembly for a fire-resistant partition wall in steel stud construction having rectangular hollow profile sections 1 as steel studs and, if appropriate, transverse struts as well as non-flammable wall panels 3 to be attached thereto is further developed in such a way as to facilitate installation and any (partial) removal which may become necessary. In addition, it is intended that lines can be laid more easily than hitherto. For this purpose, shell profile sections 2 of a non-flammable, non-metallic material of adequate mechanical strength are provided, which cover the hollow profile sections 1 on one attaching side as well as the two inner sides and at the same time form a bearing and a fastening base for the wall panels 3 or the like. Consequently, there is no direct fastening of the wall panels 3 to the hollow profile sections 1. Expanded mica which has been pressed into a solid form by the addition of binders is envisaged as the material for the shell profile sections 2, if appropriate also for the wall panels 3 and similar component parts. <IMAGE>

Abstract: Positioning of a scan line (L) relative to a recording medium drum (15) of a polygon printer is established by independently adjusting blocks (35, 36) mounted on a scan line generating optics module (10) through adjustments made to an external beam sensing fixture (52). Inverted V-notches (38) used for nesting the blocks (35, 36) onto cylindrical surfaces of drum bearings (33) are nested onto corresponding cylindrical surfaces of fixture ends (54, 55). X, z, ϑ x  and ϑ z  positions are then set by x and z direction adjustment screws (44, 45, 49, 50) mounted on a support structure (73) to make adjustments in the fixture positions against the bias of springs (100). Clamping screws (45, 46) pass through oversized holes (47, 48) on blocks (35, 36) to releasably lock blocks (35, 36) after adjustment. The z direction adjustment includes levers (85) and dual ball socket assemblies (95, 96, 97) so that adjustment of the ϑ y  position of fixture (52) will simultaneously occur to maintain a constant angle of incidence during adjustment, in response to the travel of a wheeled member (60) against a constant radius frame surface (70).
