Title: Emergency telephone connection holding system - prevents disconnection by applying hold potential continuously to lines
Inventor: BALCEROWSKI HERBERT
IPC: H04Q3/00
Filed: 1973-08-01
Abstract: The emergency telephone connection holding system prevents the emergency call being lost through a disconnection by applying hold potentials continuously to the lines leading to the calling terminal. The potential is applied by a hold relay whose contacts also apply a voltage to a time switch. After a delay of e.G. 40 seconds the time switch neutralises the disconnection relay which is then held by its own contacts. The disconnection relay interrupts the hold relay circuit, thus allowing the latter to return to its original state and disconnecting the hold potential from the telephone line.

Title: Hydraulically coupled articulated axles of trailer - produces opposite deviations of the axles in the same group
Inventor: SCHMIDT ULRICH PROF DR ING
IPC: B62D13/00
Filed: 1973-11-27
Abstract: The axles of a trailer are coupled in order to ensure correct alignment of axles on turning and to eliminate the high straightening moments exerted by rigid axles of a heavily loaded trailer on turning. The lateral instability of the trailer train is also eliminated by the hydraulic coupling of the axles so that opposite deviation is produced in the axles. This arrangement ensures also that the effective width of vehicle on turning is reduced, and the straightening moment on turning is equal to that of conventional articulated axles. In the case of two axles opposite deviations are used and in the case of three axles the first and third axle or first and second axle can be coupled. However, in the last case the straightening moment is not minimum.

Title: Separately excited DC machine - with chopper controlled field and essentially constant current armature supply
Inventor: GURWICZ DAVID
IPC: H02P7/282
Filed: 1974-08-13
Abstract: The application is to constant torque, variable speed drives for bobbin winders and similar machines. The motor armature is fed with direct current from a rectifier connected to an a.c. supply via a choke. The supply voltage is substantially higher than the motor back e.m.f. and the choke serves to limit the current to a nominally constant value. The field windings are supplied from a second rectifier also connected to the a.c. supply via a choke. A thyristor chopper under the command of a control unit adjusts the field current to the required value for the selected speed by alternately shunting the rectified current through, or away from, the field winding.

Title: Sewage sand trap - has inflow cylinder offset against oblique sand collecting cone with aerator and sand pump
Inventor: KNOOP ROBERT
IPC: B01D21/26
Filed: 1975-03-01
Abstract: A sand trap for sewage plant consists of an inflow chamber, shaped like a hollow cylinder which is offset to one side of the cylindrical upper part of the tank and receives the sewage inflow tangentially. A sand collecting hopper with an aerator and the suction nozzle of a sand pump is an oblique cone which is offset in a direction opposite to the inflow chamber. It lies in vertical projection outside the projection of the inflow chamber. This ensures that no frothing occurs in the inflow chamber as the air bubbles rise to the surface outside the inflow chamber. It prevents froth and suspended particles from being entrained with the sand by the sand pump and being transported to the sand dump.
Patent DE-2513566-A1 (DE)
Inventor: CHAIRES ANNE MARIE
IPC: G06V30/262
Filed: 1975-03-27
Abstract: A binary reference matrix apparatus is diclosed for verifying input alpha words from a character recognition machine as valid linguistic expressions. The organization of the binary reference matrix is based upon the character transfer function of the character recognition machine. The alphabetic character stream for each word scanned by the character recognition machine, is mapped into a vector representation through the assignment of a unique numeric value for each letter in the alphabet. The vector magnitude and angle so calculated constitute the address data for accessing the binary reference matrix. The point accessed in the matrix will have a binary value of 1 if the scanned word is valid and will have a binary value of 0 if the scanned word is invalid. The organization of the binary reference matrix minimizes the size of the array needed for accurate verification by choosing numerical values for the alphabetic characters in an inverse proportion to the characters read reliability in the character recognition machine, as determined by the empirical measurement of the character recognition machine, character transfer function.

Title: Offshore drilling platform auxiliary device - with coupled power cylinder for closing phase of leg erection
Inventor: VOGEL RUDOLF DR
IPC: E02B17/02
Filed: 1975-05-22
Abstract: An offshore drilling platform which is floated into position with all legs splayed out in a horizontal plane has two legs which are rigidly joined to a V-structure on shore and a single opposing third leg. The legs are brought together after arrival on site by engaging a socket at the top of the twin legs with the head of the piston rod of a power cylinder connected to the third leg. The socket is coupled to the head by a spring-loaded latch and a solid connection can then be completed by bolting several plates together. This prevents the possible sudden and destructive forces caused by the contact of the plates if the legs are allowed to drop freely. This movement can now be controlled very sensitively independent of wave action.
