Title: Decontamination of waste liquor contg. radioactive iodine cpds. - by expelling iodine from acidified liquor and filtering air or oxygen used
IPC: G21F9/06
Filed: 1976-10-02
Abstract: Decontamination of waste liquor cong. radioactive I cpds. esp. I131 isotope, from hospital nuclear-medicinal stations, involves adjusting the H ion concn. to a alue at which the I is expelled as vapour or gas by introducing air, O2 etc., filtering or pptn. of teh expelled mixt., discharging the air and decontaminating the filter material contg. the I fraction, e.g. in a decay vessel. The decontaminated water is discharged to the sewerage system. Since only the filter material, instead of the water, needs decontamination in the final stage, only small and therefore less costly equipment is needed and maintenance is simplified.

Title: Bandwidth limited digital PCM transmission system - with frequency band divided in three zones, with phase correction better in middle zone
Inventor: DOEMER JOSEF
IPC: H04L27/02
Filed: 1976-12-17
Abstract: The system has a high-pass or a band-pass characteristic for transmission of a pseudo-ternary code using approx. sin2-shaped pulses of double bit width for regeneration. Frequency band to be transmitted is divided for phase correction into a core and two outer zones, whose limits are determined by dominant frequencies (f1, f3) representing spectral lines of those two pulse trains which contain all transient processes. Accuracy of phase correction in the outer zones is lower than in the core zone.

Title: Digital indication of measurement removing non-linearities - converting ROM output to proportional voltage using A=D and voltage to frequency converters to supply counter
Inventor: OTT ALBERT DIPL ING
IPC: H03M1/00
Filed: 1976-12-18
Abstract: Non-linear electrical measurements of physical sizes are converted to give the same linear relationship on the indicating instrument as occurs for the physical size being measured. A reference signal is passed through an integrator to give a voltage increasing with time which can be recycled by a switch. The comparator compares this voltage with the measured voltage and holds a gate open whilst the measured voltage is greater than the time dependent voltage and so converting the measured voltage to time. A summing counter counts the pulses from a pulse generator during the period that the gate is open. the highest binary value of the counter is connected to the read only memory.

Title: Adjustment of gear play in roller piston vacuum pumps - having roller pistons circulating within housing and adjustment is via eccentric bearing bushes
Inventor: LANG HERMANN ING GRAD
IPC: F01C21/02
Filed: 1977-01-22
Abstract: Fine adjustment of the gear play in roller piston vacuum pumps and roller piston blowers is applicable where roller pistons circulate within a housing, one below the other, supported with roller bearings in bearing brackets, free of contact with the housing. There are bearing bushes in the bearing brackets and their inner cylinder face, which accepts the roller bearing, is eccentric to the outer cylinder face which accepts the bush in the bearing bracket. The bearing bush is fixed in the bearing bracket so that it can turn. Consequently, because of the eccentricity, the axial spacing is greater or smaller according to each position of the bearing bushes.

Title: Cross-bar switch for telephone exchanges - has additional cut=out in one shift rail to avoid damage to contact
Inventor: DOST WILLIBALD ING GRAD
IPC: H01H67/26
Filed: 1977-03-22
Abstract: The crossbar switch for telephone exchanges is designed to prevent bending, jamming or other damage to the spring contact arm occurring in the event of reversed switching sequence or incorrect operation. Each contact combination selection is done via line and column shift rails (9, 10) made of insulating material such as plastics. When switching selection takes place, a certain sequence must be observed when operating the shift rails to avoid jamming and consequent bending of the contact spring. One of the shift rails - the column rail - (10) has an additional cut-out section (14) to prevent jamming. If this rail is operated before the second rail, the contact wire (2) is moved by the second rail into the cut-out. In this position, the wire cannot be bent.
