Abstract: The invention relates to a process for the preparation of 3-hydroxyalkanals having 3 to 12, in particular 3 or 4, C atoms, by hydration of the basic 2-alkenals with water in a homogeneous phase in the presence of an acidic catalyst. 
<??>The previously known hydration by means of mineral acids or carboxylic acids as catalyst results in poor space-time yields and/or poor selectivities. These disadvantages can be avoided when a dissolved acid/base buffer is used as catalyst which results in a pH of 2 to 5 in the reaction mixture and whose acid component and the corresponding base are present in the reaction mixture in an amount of 0.5 to 40% by weight in total. The preferred buffers composed of a lower monobasic carboxylic acid and a tertiary amine can be recycled in a simple manner.

Date Mar. 31, 1994A microscope (1) is described which has an adjustment knob (2) arranged on the microscope (1) and an encoder (6) assigned to the adjustment knob (2). The encoder (6) is connected to a control device (3). The control device (3) is assigned positioning motors (4, 14, 18, 23, 24) for motorized setting of different microscope functions. The preselected function which can be controlled by motor is preselected via switches (7, 11, 15, 19, 21) arranged on the microscope (1) and triggered via the control device (3) as a function of the encoder pulses generated by the adjustment knob (2). The motor drives are assigned sensors (8) which detect the operating position of the activated microscope function. When the maximum operating position is reached, a braking motor (9) connected to the adjustment knob (2) is activated via the control device (3) and renders the rotation of the adjustment knob (2) more difficult up to complete blockage.

Abstract: The acetabular cup (2) comprises a metal outer shell (4), a plastic intermediate shell (5) and a metal inner shell (6) which can be positively inserted into the intermediate shell. The outer shell (4) is divided up into segments (4a, 4b, 4c, 4d, 4e) by slots (9) which are open towards its equatorial edge region. The outer shell (4) and the inner shell (6) are rigidly supported relative to one another via an attachment part (8) in the direction of a common principal axis (A) and connected so as to be fixed against rotation via a fastening element (15) eccentrically offset relative to this principal axis (A). The intermediate shell (5) is designed with a passage opening (20) receiving the attachment part (8) and with an outer surface (21) which has a support part (21a) intended to rest against a part of the inner surface (18) of the outer shell (4) and delimits a play (S) outside this support part (21a) with the remaining part of the inner surface (18). This play permits corresponding relative movements of the intermediate shell (5) containing the inner shell (6) and at least one of the segments (4a, 4b, 4c, 4d, 4e) of the outer shell (4) perpendicular to the principal axis (A). Upon loading, the implanted outer shell (4) can deform elastically with the bone part surrounding it, whereas the spherical shape of the inner shell (6) is retained. <IMAGE>

Abstract: To ensure interference-free transmission of digital messages, very high demands are made on the accuracy and stability of the clock generators. It is known to use for this purpose microprocessor-controlled digital phase-locked loops and to use for this expensive highly stable crystal oscillators. An accurate system clock should be delivered even if the reference clock fails. Contradictory demands are made on the phase-locked loops, on the one hand a wide bandwidth to achieve a small phase timing error and on the other hand a narrow bandwidth in order to keep down the influence of jitter and wander on the clock accuracy when the reference clock fails. It is the object of the invention to specify a circuit arrangement for an inexpensive clock generator which should deliver a highly accurate clock frequency even when the reference clock fails. According to the invention, the contradictory demands on a phase-locked loop are distributed over two phase-locked loops, both of which are controlled by a microprocessor and which are allocated only one oscillator. A first phase-locked loop (1) having a narrow bandwidth is connected via a change-over switch (3) to a second phase-locked loop having a wide bandwidth. When the reference clock fails, the output clock of the first phase-locked loop (1) is switched as reference clock to the second phase-locked loop (2). <IMAGE>

Abstract: A welding machine for manufacturing frames, especially window frames, has six or more welding heads (1, 2, 3, 4, 5, 6) for welding the individual frame parts together. Four welding heads (1, 2, 3, 4) have welding tools (11, 12, 13, 14) aligned with the mitres for welding the corners and the other heads (5, 6), which lie between the corner welding heads, are used for welding in an abutment (10) and have angled welding tools (15, 16), each having a long shank (17) enabling it to weld corners. In a frame welding process: (a) a part of a frame is manufactured, especially an A-frame; (b) a reinforcing bar is introduced into a channel of the part frame; and (c) the frame is completed by welding in the remaining profile. Preferably the angled welding tools (15, 16) also have a short shank (18) for welding in of an abutment (10). The welding heads (5, 6) can be operated in conjunction with both pairs of corner welding heads (1, 4; 2, 3) in a single welding stage to simultaneously manufacture two window frames. Two welding heads (2, 3), each with an angled welding tool, are used to weld a common profile completing an prewelded A-frame. Holders for the profiles before and during welding move in the plane of the frame and/or at a right angle to it or press the profile against the prewelded frame or another profile.

Abstract: The fuel is fed centrally into a fire tube (3), where it is mixed with combustion air in a combustion zone. The air exits through first and second air line nozzles (4 or 5) which are arranged in two directly adjoining rows (6, 7) and inclined in the direction of counterflow at an angle of 60° to the axis of the fire tube. The distance (x) between the fuel nozzle (9) and the openings of the first air line nozzles (4) is 0.70 times the diameter of the fire tube. In addition, the second air line nozzles (5) extend into the fire tube by a distance (y) which is 0.17 times the diameter of the fire tube. The total cross-section of the second air line nozzles (5) is 0.6 times that of the first air line nozzles (4). A highly turbulent toroidal eddy forms inside the fire tube (3) which generates a very homogeneous mixture across the cross-section of said fire tube (3). This results in lower NOx values and even temperature distribution already inside the fire tube.
