Patent DE-2644176-A1 (DE)
Inventor: OBERMAYER HEINZ
IPC: G11B17/028
Filed: 1976-09-30
Abstract: The arrangement serves for firmly clamping, for example, so-called head support plates on the positioning device of disk stores in trapezoidal grooves of a U-shaped support. Bearing surfaces are formed at an angle of about 45 DEG  on the upper edges of the disks. In the one leg (3) of the U-shaped support (1) there are bores (4), in which circular-cylindrical thrust pieces (5) are movably seated and, with the aid of a screw bolt (6) in each case, can be tightened with respect to the other leg (7) of the U-shaped support (1) and each have a 45 DEG  bearing surface. Relief-cutting of the 45 DEG bearing surfaces, located on the side remote from the thrust pieces, of the disks (2) produces in each case two bearing points (10, 11) symmetrically to the thrust pieces. As a result, the aligning and fastening of the disks is improved. <IMAGE>

Title: Data transmission system for radio direction finders - uses telephone lines for channel and Hilbert transformation data
Inventor: BAUR KARL PROF DR
IPC: G01S5/00
Filed: 1977-01-22
Abstract: The data transmission system for direction finding of the Watson-Watt type uses digital processing to enable the information to be transmitted over telephone lines. After scanning via Hilbert transformation, the digitised signals are stored prior to transmission. At the receiver, the data is converted to parallel form (1) and then under-goes digital to analogue conversion (2) for each of the three channels and their Hilbert transforms. The D/A converters are connected to ring modulators (3). The outputs of the modulators are fed to adder (6) whose output signals are available for display purposes. To reduce the bandwidth of the transmission, data compression and data rate reduction is used.

IPC: B22C1/20
Filed: 1978-11-02
Abstract: A moulding compsn. for producing casting moulds and cores consists, by wt., of (a) 10-35% soln. of hydrolysed Et orthosilicate, as binder, (b) 0.2-2% organic soln. of a polyorganosiazane, (I), as hardener bringing about the gelling of the Et orthosilicate, and (b) balance to 100%, filler. (I) has formula left brace (R2SiNH)n R'Si(NH)1.5 m right brace k (where R is Me; R' is Me or Ph; n = 1, k is 4 to 10 and m is 1 to 3). The moulds and cores can be used in precision casting. The use of (I) causes 2 consecutive reactions in moulding compsn. : (i) hydrolysis of (I) with formation of siloxane bonds, using up "ballast" water of filler, (ii) promotion of Et orthosilicate-gelling by the NH3 released. (I) is less toxic than previously used triethanolamine. The flexural strength of the hardened moulding compsn. may be 20-25 kp/cm2, i.e. 1.5-1.75 x higher than on using triethanolamine. (I) is evenly distributed and the moulding compsn. hardens evenly, without risk of cracks. (I) is introduced esp. a 20-40% soln. in an organic solvent. A pref. compsn. contains 15-25% binder soln., 0.5-1% of a 20-40% soln. of (I), balance filler. Describes the prepn. of a moulding compsn. for cores used in casting steel to form centrifugal pump wheels. The compsn. contained 30% quartz and having particle size 0.08-4.4 mm, 45% quartz dust having particle size 0.01-0.06 mm, 24.25% soln. of hydrolysed Et orthosilicate and 0.75% of a 30% soln. of (I) in toluene. After hardening 5 min., the core was heated to 900-1100 degrees C in 1-2 hrs. at 100-150 degrees C/hr and achieved flexural strength 30-80 kp/cm2.
