Title: N-mono or N,N-di:substd. urea cpds. prodn. in high yield - comprises reacting ammonium isocyanate with prim. or sec. amine in diluent, without needing to isolate free isocyanic acid
Inventor: STERN GERHARD DIPL ING DR
IPC: C07C275/24
Filed: 1991-08-21
Abstract: Prodn. of N-mono- or N,N-di-substd. urea (I) is carried out by reacting NH4NCO with a prim. or sec. amine (I) in a diluent (III). (III) is inert under the reaction conditions and pref. is an aliphatic or aromatic (chloro)hydrocarbon, ether, alcohol or water. Alternatively, (II) also acts as (III). NH4NCO and (II) are used in equiv. amts., unless (II) also acts as (III). Either (a) (II) is added to a stirred mixt. of NH4NCO and (III) or (b) NH4NCO is stirred into (II) and opt. (III) at temps. from -20 deg. C and room temp. and reaction is completed by (a) heating to the reflux temp. of (III) or (b) increasing the reaction temp. (I) is isolated from the reaction mixt. in the usual way. ADVANTAGE - NH4NCO can be used directly, without isolating the free acid. The process is simple and gives good yields. In an example, a soln of 28.1g (0.15 mole) dodecylamine in CHCl3 was added to a suspension of 10.8g NH4NCO (83%; 0.15 mole) in 90 ml CHCl3 at room temp. The mixt. was stirred for 1 hr, then heated 2 hr. under reflux. After cooling, the ppte. was filtered and dried, giving 33.5g dodecylurea (98% of the theory), m.pt. 102-105 deg. Cs ad

Title: Drying machine - has a rack conveyor which accepts the objects without touching one side and releases them when dry
Inventor: MUELLER THOMAS
IPC: F26B15/08
Filed: 1991-10-12
Abstract: A drying machine for flat objects has an endless chain conveyor with carrier rack, angled on the top horizontal stretch at over 90 deg.. It has an entry and an exit for the objects. The conveyor track descends towards the exit, with the rack held almost vertically. Pref., an endless chain (14) revolves around a large wheel (5), and a smaller one (3), and having a descent from the horizontal near the end of the movement (2), so that the spokes of the rack (16) move from an angle of 90 deg., to approx. 88 deg. along the section (26). USE/ADVANTAGE - The system allows objects to be loaded with little or no front contact, so that they may be soft and require drying to harden as they pass through the machine, without damage. Suitable for flat objects e.g. circuit boards, having been varnished, or similar objects which harden as they dry.
Patent DE-4136879-A1 (DE)
Inventor: OHMS FRANZ DIPL ING
IPC: H02M7/538
Filed: 1991-11-09
Abstract: In order to limit the heating-current for, in particular, a travelling-wave tube (WR) during the cathode-heating time, the invention proposes that alternating current supplied to the heating filament (Rf) through a transformer (Tr) be reduced from a high initial value to a lower nominal value. Since most of the heating voltage decays during the cathode-heating time as stray inductance (Ls) in the transformer (Tr), no other current-limitation device is necessary.

Title: Method for correcting a transmission-related time offset
Inventor: HELLER ARTHUR
IPC: H04N5/04
Filed: 1993-03-25
Abstract: To correct a transmission-related time offset between a picture signal and a sound signal transmitted separately therefrom, a defined area for transmitting an additional information item, which can be added together up to a maximum value, is provided in the video signal to be transmitted. Each video signal process which results in a significant fixed or variable delay time between its input and its ouput provides an additional information item quantifying this delay time contribution. On the video output signal of such a video signal process, the additional information quantifying the delay time contribution of this process is impressed in the previously defined area in such a manner that it is added to the value present in the video input signal. At the signal sink, the aggregated additional information is taken from the previously defined area of the video signal and conditioned with respect to polarity and proportionality in such a manner that it sets the controllable sound delay device, to the setting input of which it is supplied, to exactly the delay time corresponding to the aggregated additional information.

Title: Side window for motor vehicle doors
Inventor: BOTSCH HERMANN
IPC: E05F11/44
Filed: 1993-04-06
Abstract: The invention relates to a side window for motor vehicle doors with a lowerable and raisable window pane which above the belt line of the motor vehicle door is guided at the sides in a window frame, and whilst being lowered is held on each side edge by sliding elements which are in alignment in the vertical direction and are inserted in U-shaped holders mounted on the door body. To ensure a smooth-running lifting and lowering movement of the window pane with adjustment tolerances of a sufficiently large size for simple and rapid assembly, each sliding element is designed as a U-shaped, spring plastic clip which is accommodated in the associated holder in a manner such that it can pivot to a limited extent in the sliding plane of the window pane. For this purpose, the limbs of the plastic clip bear short round pegs which engage in a form-fitting manner in corresponding openings in the limbs of the holder, and a clearance remains between the webs of the plastic clips and holders.
