Title: Safety circuit for railway crossings - detects presence of trains using resistance bridge attached to rails which is unbalanced when short circuited
Inventor: HELLER FRED-HARALD
IPC: B61L29/28
Filed: 1974-12-30
Abstract: A safety circuit for use at railway crossing and at similar installations, detects the presence of a train and a warning light and possibly a warning horn are activated. It consists basically of a low impedance resistance bridge consisting of four resistances (R1, R2, R3, R4) one of which (R1) is the resistance of a length of rail and another of which is a low value resistance (R2) connected between the rails. The other two are variable and are adjusted until the bridge is balance when no train is in the vicinity. When a train approaches, the bridge becomes unbalanced and a voltage is produced which is used, via an amplifier and Schmitt trigger, to switch a relay. The contacts of this then produce the alarm signal required.

Title: Electromagnetic irradn. of food prod - treating the prod. at much lower frequency than container gas space
Inventor: BACH JEAN DR
IPC: A23L3/04
Filed: 1974-05-09
Abstract: Heat treatment process for food preservation, e.g. sterilization of milk products, employing high frequency electromagnetic irradiation. The product in its container is immersed in a bath of liquid to a depth at which the level of the top surface of the product remains slightly above the level of liquid in the bath, i.e. the gas space above the product is completely above the level of bath liquid. In this position the product is irradiated between electrodes emitting electromagnetic energy at a frequency low enough to ensure penetration right through the container, i.e. wavelength of the order of metres to decametres; simultaneously, a much higher frequency electromagnetic field, with a very limited penetrating power, is set up at right angles to the transverse field between the electrodes, e.g. from a parabolic antenna above the container, and irradiates the gas space above the product, the wavelength in this case being of the order of centimetres to decimetres. Heat treatment such as sterilization for the preservation of food products in non-metallic containers such as plastic pots, glass jars and bottles, in partic. milk products such as yoghourt and cream dessert, meat and meat pastes.

Title: Switch operating flow threshold monitor - is for high pressure liquids which have good viscosity and mechanical properties
Inventor: RAUSCH GEORG
IPC: G01F1/38
Filed: 1975-01-09
Abstract: The flow threshold monitor, with good viscosity and mechanical properties, activates a switch when a liquid under high pressure has a flow rate through the device of less than a set threshold. The device consists basically of a shaped chamber in which a movable body (2b) obstructs the flow against the pressure of a spring (4). A long rod (3b) is attached to the movable body (4) and this operates a lever (10) via a ball connection (8). This in turn operates a microswitch (16). In the non flow position the ball connector (8) fits into a narrow neck on the rod (3b) and the switch is in one position, whereas a sufficiently large flow occurs, and ball and lever are displaced laterally and the switch position changed. A lower flow threshold is thus monitored.

Patent DE-2520730-A1 (DE)
Title: Output stage of heart-pacemaker - is modified to eliminate decay time of stimulus voltage and allow use of adaptive pacemaker
Inventor: REHAK JAROSLAV DIPL ING
IPC: A61N1/36
Filed: 1975-05-09
Abstract: A heart pacemaker of the usual kind provides a stimulus pulse, which initiates not only a heart cycle but also an interval during which the input circuits of electrocardiographs etc. which use the same electrode within the heart, are overloaded, and their outputs accordingly cease to communicate meaning. In particular, the interval is too long to permit the use of the more elaborate adaptive pacemaker, which responds to the momentary state of the heart muscle and needs information about it immediately the pulse has been given. This is corrected by including in the output stage of the usual simpler pacemaker a source of compensating current or voltage, which has the effect of reducing the blacked-out interval to a very short time.
Patent DE-2524058-A1 (DE)
Title: Conversion of heat into electrical energy - by electrolytic decomposition and recombination of aq. halogen cpds.
Inventor: HOEGE HELLMUT DIPL ING
IPC: H01M8/18
Filed: 1975-05-30
Abstract: The parent describes a process for converting heat into electrical energy, in which an aq. electrolytic cpd. in decomposed electrochemically in a circuit. The decompsn. voltage lies below 1.23V to prevent oxygen sepn. at the anode and below the recombination voltage at the reaction temp. The cpd. consists of a gas, together with bromine or iodine in view of the high chemical activity required at the normal temp. of the surroundings. The individual substances generated are introduced into a recombination cell in which they recombine to form an aqueous compound giving up a direct current. The cpd. is recycled to the decompsn. cell and the decompsn. energy is supplied by the recombination cell. Heat from the surroundings flows into the decomposition cell as a result of the cooling taking place in it. In the present specific. the substance generated at the anode is the halogen chlorine and the electrolysis and recombination are carried out according to the vapour press. curve of chlorione at such a gas temp. and press. that the chlorine liquefier immediately upon sepn. at the anode. Although chlorine is normally a gas at room temp. the cell can be operated in such a way that no special measures need be taken to separate it as a gas.

Title: Brightness distribution correction for screen display unit - has matrix of image points associated with electronic light signal processing components
Inventor: SIPOS BALINT
IPC: G09F9/00
Filed: 1976-09-29
Abstract: The matrix of image points receives at all the image points the same brightness control signal. The brightness distribution of the image points is detected by a photographic plate which is then placed as a negative in front of the screen. This negative thus has at points of stronger illumination a weaker light transmittance and thereby causes the brightness correction. Too large or too small brightness of individual image points is compensated. The period of exposure of the plate must be such that the negative is largely clear and transparent at points of normal brightness.
