Title: Method and device for the protection of friendly hit combat vehicles
Inventor: SIEBECKER HANS DIPL ING DR
IPC: F41H3/00
Filed: 1983-03-26
Abstract: Some protection of friendly hit combat vehicles and their crew is seen in a halon gas which is released via optoelectronic sensors and their logic module at the moment of the hit and which flows out of a pressurised bottle and extinguishes the seat of fire. However, the quantity of halon gas guarantees protection only for a maximum of two hollow-charge hits, and therefore a bombardment continuing thereafter always still constitutes a danger. This can be reduced in that, after the first hit, the already present or additional sensors trigger conflagration or explosion bodies provided at specific outpoints on the vehicle, in order thereby to simulate the combat incapacity of the vehicle and crew. Alternative or additional protection is seen in the provision of a smoke screen for the vehicle.

Title: Alkaline protease and process for the preparation thereof
Inventor: ICHISHIMA EIJI
IPC: C12N9/54
Filed: 1983-08-08
Abstract: The alkaline protease is called API-21 and has the following chemical and physicochemical properties:   (1) activity: hydrolyses casein under alkaline conditions; the optimal pH range is 10 to 11 and the optimal temperature range for the activity is 45 to 50 DEG C; (2) stability: no reduction in the enzymatic activity is observed on heating for 10 minutes without substrate at a pH of 10 and up to 40 DEG C, but a 90% or more reduction in enzymatic activity is observed on heating for 10 minutes at a pH of 10 and at 50 DEG C. Inactivation occurs in 10 minutes at a pH of 8 and at 50 DEG C, and complete inactivation takes place in 10 minutes essentially at a pH of 8 and at 60 DEG C. The protease is stable under alkaline conditions, in particular in a pH range from 7 to 11.5, and is resistant to freezing and freeze drying; (3) enzyme molecule: the protease is a protein with a molecular weight of about 22,000 determined by gel filtration, an isoelectric point of 7.4 determined by the electrofocusing method, an absorption maximum at 275 to 282 nm in the UV absorption spectrum, the IR absorption characteristics shown in Fig. 5, and has a serine residue at the active centre.

Patent DE-3330816-A1 (DE)
Title: Safety belt for car occupants
Inventor: SCHROTH CARL JUERGEN
IPC: B60R22/02
Filed: 1983-08-26
Abstract: Braces-type belts consisting of a pelvic belt and of two shoulder belts are used in sports cars. The shoulder belts are fastened as centrally as possible to the pelvic belt, in order to make the necessary contact of the belt user with the vehicle. The disadvantage of these belts is that, in the event of an accident, the belt forces of the shoulder belts act on the pelvic belt at right angles and pull this up out of a position on the hip-bone into the genital area of the body. In addition, the seats are compressed, so that the belt user executes a relative movement obliquely downwards in the direction of travel. In the safety belt according to the invention, the shoulder-belt ends located at the seat form integral parts of the pelvic belt. They are guided in the manner of a block and tackle. This results in a force ratio between the shoulder belts and the pelvic belt, by means of which, in the event of forces acting on the shoulder belts, the pelvic belt is always pulled tautly up against the hip-bones. In the event of an accident, the pelvic region is retained perfectly. However, the upper body can execute a relative forward movement which is desired for reasons of load. <IMAGE>

Title: Method for measuring frequency or period
Inventor: REESE UDO DIPL ING
IPC: G01R23/10
Filed: 1983-10-06
Abstract: To measure frequency or period of an unknown pulse train (I1), its pulses (n1, n2, ...nx) are counted during a gate time (TG). Between in each case two pulses (n0-n1, n1-n2, ...nx-nx+1) of the unknown pulse train (I1), the pulses of another pulse train (I3), the frequency (f3) of which is much higher than the frequency (f1) of the unknown pulse train (I1), are counted. If the beginning of the gate time (TG) is detected during one such counting period (n0-n1), the counts at the beginning (Z0) and end (Z2) of this counting period and at the beginning (Z1) of the gate time (TG) are stored. As well, the counts (Z3, Z4, Z5) of the counting period (nx-nx+1) at the end of the gate time (TG) are stored. From the number of pulses (x), the gate time (TG) and the counts (Z1...Z5), the unknown frequency (f1) is determined in accordance with the equation.  (TG . f1 = x + (Z2-Z1)/Z2-Z0-(Z5-Z4)/Z5-Z 3) <IMAGE>

Title: Press-stud connection
Inventor: NYSTEN BERNHARD DIPL ING
IPC: A44B17/00
Filed: 1983-12-29
Abstract: In a press-stud connection which consists of a functional part and of an attachment part serving for the mounting thereof on a sheet-like structure, pattern carriers are used for decorative purposes. In order to obtain lasting and easily manufactured decoration of this press-stud connection, it is proposed that a transparent web, printed on the back, be used as the basis, one section thereof forming the pattern carrier. The printed layer which produces the pattern is always used on the inside surface of the pattern carrier used for decoration, so that its colour acts through the transparent material of the web onto the visible outer surface. These pattern carriers need not be used only as caps for the fixing parts but can also, advantageously, be shaped to form the functional parts of the press studs which are equipped with domed surfaces.
