Title: Car wash unit monitoring system - with light barriers to disconnect unit if interrupted in wrong sequence
Inventor: ORDINAIRE FRANCOIS
IPC: G07C9/00
Filed: 1976-03-05
Abstract: Supervisory system for a car washing unit has a double light barrier (L1, L2) arranged horizontally across the exit (2) from the unit. The light barriers are at the same height above ground and parallel to each other, and are separated in the direction of vehicle movement by a distance less than a vehicle length but sufficient to enable a person to stand between them. The barriers are wired so that a counting pulse is produced when the outer barrier is interrupted whilst the inner barrier is still interrupted, whereas the washing unit is disconnected if the outer barrier is interrupted first. The light barriers are at a height of e.g. 20-80 cm, pref. 40 cm above the base of the washing unit.

Title: Laser beam trans receiver recording unit - detects movement of opaque workpiece when light barrier intercepted, switching off receiver until set distance traversed
Inventor: HAUSER GUENTHER DR ING
IPC: G06M1/10
Filed: 1976-04-22
Abstract: The recording instrument is designed for any design of workpiece which is made of non-transparent solid material which a minimum volume of 0.2 cmm. The workpieces are detected with the aid of a light barrier which is driven by a laser. The laser beam is fanned out after the measured distance by a diffraction on a diaphragm. The light receivers are arranged in the light minima or light. After the light beam has made contact with the workpieces for the first time, the light receiver or light transmitter is switched off until the workpiece has travelled through the measured distance. The measured time is used to switch off the light receiver.

Title: Measuring factor XIII content of blood - by determn. of coagulation time after incubation with plasmin and thrombin
Inventor: JACOBI ECKART DR MED
IPC: C12Q1/56
Filed: 1976-05-19
Abstract: Method for determining the fibrin-stabilising factor (factor XIII, I), esp. in human blood, comprises measuring the coagulation time of a sample of the blood. The measurement is pref. carried out in a soln. of a plasma lysate obtd. by incubation with thrombin and plasmin. Then addn. of thrombin distorts the coagulation time and the (I) concn. is determined by measuring the extent of this distortion. A reduced (I) content is esp. revealed by measuring the accelerated coagulation time relative to the normal time. A test kit for the assay comprises a factor XIII-reagent and thrombin in separate containers. Compared with known (e.g. antibody inhibition) procedures, this method is qick, simple and inexpensive, so suitable for routine use. It is useful in diagnosis of congenital (I) deficiency, wound-healing abnormalities and malignant blood disease.

Title: Nuclear plant with increased safety - provided by external humid clay layers to absorb discharged activity
Inventor: MORLOCK GUENTER DIPL PHYS
IPC: G21D1/00
Filed: 1976-07-26
Abstract: The safety of the surroundings of a nuclear plant, in the event of a containment vessel failure, is increased by surrounding the nuclear component, opt. other plant components also, with soils, partic. clay or the like, which possess a low permeability to gases and liquids in the humid state. Pref. the soil, clay etc. is maintained permanently humid by underground irrigation or sprinkler equipment. The material may be laid in layers with water-permeable intermediate layers, such as perforated plastics sheets, separating them. Conventional frost protection may also be used.

The addition of an external layer of soil increases the pressure resistance of the containment vessel. The effect of permeable plastic intermediate layers is to resist the penetration of radioactive substances.

Title: Angle of rotation measuring circuit - uses HF triangular voltage supplies and scans contactless resistance ring
Inventor: BROEMME ALBRECHT
IPC: G01D5/165
Filed: 1976-11-30
Abstract: The analogue linear directly proportional electromechanical transducer measures angles of rotation. It avoids nonlinearities associated with sinusoidal power supplies because of the relation between phase and rotation angles. The angle is measured by scanning a resistance ring using slip contacts. The ring is powdered from four triangular waveform voltage sources of equal amplitude, frequency, and resetime and shifted w.r.t. each other by ninety degrees. The supply voltages have sufficiently high frequency to enable contactless capacitive scanning.

Title: Aerating tunnel supports for compost heap of decomposing waste - comprising trestles standing on pallets with perforated tops
Inventor: WILLISCH HANNES
IPC: C05F7/00
Filed: 1977-03-18
Abstract: Supports of parent patern are for a compost heap in which household rubbish, drainage sludge, etc. are decomposed cleanly to produce an dreanic fertiliser. The supports form longitudinal tunnels in the base of the heap communicating with vertical chimney shafts to produce continuous oxygenation. The walls of the supports are perforated to allow circulating air to pass thro. In addition, the supports are carried on pallets which are located between the supports of two adjacent tunnels. The top platforms of the pallets are perforated to allow air pass freely through i.e. pref. in the form of a grill or screen construction. The perforated pallet tops assist aeration and speed the decomposition process. The possibility of unventilated dead spots, together with the danger of offensive putrefaction, is thus eliminated.

Title: Analysis of biological specimens by ionising heat-decomposition prods. - with three-dimensional plotting of results giving reproducible results
Inventor: RISBY TERENCE H
IPC: H01J49/04
Filed: 1977-04-28
Abstract: Samples are heated in an identical pattern with a non-isothermal, time-dependant temp. graph, to decompose then and produce the thermal decomposition products. Products are ionised to produce minimum destruction and the ions current corresp. to the different mass-charge ratios of the decomposition products are detected adn recorded for each specimen as a three-dimensional array of a very large number of current values. This corresponds to all detectable mass-charge ratios within a specific range. Recording is carried out for a large number of successive intervals of time during the heating process. One dimension of each three-dimensional array corresponds to the ion currents, the second to the mass charge ratio and the third to the temp-time function. Representative values of the recorded three-dimensional array for each specimen are correlated with representative values of the arrays for the other specimens. Method is esp. for investigating specimens comprising lymphocytes, luecozytes, phagozytes, erythrocytes and thrombocytes, bacteria, yeasts, moulds fungi viruses and single-cell organisms.

Patent DE-2732788-A1 (DE)
Inventor: KRUIJSEN THEO
IPC: H02P23/28
Filed: 1977-07-20
Abstract: The method is distinguished by the fact that the motor windings are in each case connected to the DC voltage source (2), and disconnected from said source again directly and cyclically, with a phase shift of approximately 120 DEG , and by the fact that the connection and disconnection of each motor winding is carried out alternately in such a manner that the current direction through each winding (8) is in each case reversed in the successive connection periods. In this case, a first switching element (4, 6) is in each case provided for each pair of switching elements, in order to switch the current flow under load, and a second switching element (3, 5) is provided for reversing the polarity of the current direction. By limiting the switched-on times, a three-phase motor can be operated with rectangular pulses even at extremely low frequencies and rotation speeds without any overheating occurring. In addition, it is possible to dispense with an invertor by using this method. <IMAGE>

Title: Monitoring and remote control system - transmits monitoring signals as current levels converted into voltage levels for light signalling installation
Inventor: ZELLER RICHARD
IPC: G08G1/07
Filed: 1977-11-04
Abstract: One single cable core is used as the signalling wire for each installation, over which monitoring signals are transmitted to a superordinate control station, and switching on/off commands from it to the light signalling installation. Monitoring signals are d.c. voltages with different levels for different signalling criteria, evaluated in the central station in a voltage level receiver allocated to a signalling installation. Monitoring signals are transmitted from the signalling installation by modulated currents whose steps correspond to signalling criteria, delivered by a stepping generator. An evaluating resistor in the central station converts the currents to corresponding voltage steps.
