Title: Cylinder head for water cooled IC engine - has metal tubes cast in to form flow passages for cooling water to reduce total weight
Inventor: HERRMANN JOACHIM
IPC: F02B1/04
Filed: 1979-02-03
Abstract: The cylinder head has several cooling water spaces (2, 3, 4, 5) arranged round each combustion chamber recess. The spaces extend axially down the head and are open at the surface which fits onto the cylinder block. At their closed ends they are linked by transverse channels (7) which join a longitudinal channel (9). These transverse and longitudinal channels are formed by metal tubes cast in the head during manufacture. The tubes have openings (10) where they pass overthe spaces (2, 3, 4, 5). This method of construction gives a cylinder head with a low water content which nevertheless gives very effective cooling of the combustion spaces.

Title: Data transmission in both directions over one cable - using time sharing mode and regenerator with changeover circuit and store for blocks of data
Inventor: SCHEFFLER HARTMUT ING GRAD
IPC: H04L5/14
Filed: 1979-10-10
Abstract: PCM data is exchanged in a time sharing mode between two stations (A,B) in both directions over a single cable with a regenerator. The regenerator contains one receiver (E), transmitter (S), store (SP), controller (ST) and a changeover circuit (U). Data in both directions is compressed into blocks whose length plus the max. propagation time equals half a time sharing cycle. A block of data received (E) by the regenerator from the first station (A) is immediately sent (S) to the second station (B). Then the controller (ST) switches the changeover (U) and a block is received from the second station (B) and fed into store (SP) while the previous block is read out and sent (S) to the first station (A). If propagation time is less than the max., the controller (ST) waits until this has elapsed before changing over, so that time sharing cycle time is constant.

Patent DE-3018998-A1 (DE)
Title: Finger-print comparator using photodetector - detects coincidence between reference print and moving projection of actual print
IPC: G07C9/00
Filed: 1980-05-19
Abstract: The finger-print is applied to the sloping face of a prism. The finger-print is projected optically through a reference finger-print (1) on a transparent plate. Coincidence between the projected finger-print and the reference finger-print causes a first electrical output at a photodetector (12) whilst noncoincidence causes a second output. The image of the finger- print on the prism passes through a device (9) that causes it to move continuously in a given manner (e.g. in a spiral) in a given plane such that it moves in the same manner over the reference finger-print. If the finger-prints are identical the light incident on the photodetector will be greater than if they are not identical. The comparator can be used for comparing a finger-print on a security card with the user's actual finger-print in order to gain access to a building. The comparator can also be used to compare patterns other than finger-prints.

Patent DE-3031379-A1 (DE)
Title: Dynamically measuring magnetic properties of toroidal tape core - feeding prim. and sec. winding voltages to computer and measuring prim. voltage by resistor
Inventor: SCHNEIDER HANS-PETER ING GRAD
IPC: G01R33/14
Filed: 1980-08-20
Abstract: In the dynamic measurement of the magnetic properties of toroidal tape cores, esp. for deriving the hysteresis curve, the primary winding round the specimen takes a magnetising current of adjustable frequency and amplitude which is measurable by the voltage produced in a resistance, while the voltage induced in the secondary winding is a measure of the change in magnetic flux. The analogue values for both voltages are digitalised and stored before being called in at specified intervals and supplied to a computer which directly expresses the magnetic properties. These may be presented in impulse form on a plotter or printed out to show the hysteresis loop. Magnetic flux density can be determined by numerical integration of the induced voltages. The method is quick and produces more precise results than systems using an oscillograph.
