Title: Phase locking for colour TV chrominance detection - ensures local oscillator synchronises immunity
Inventor: HESS HEINZ
IPC: H03L7/113
Filed: 1974-03-09
Abstract: A network for synchronising the frequency and phase of a local oscillator to those of incoming colour television chrominance burst signals is presented. The local voltage controlled oscillator output is fed to two discriminators. To one of these the incoming signal is fed directly, whilst to the other it is fed with a 90 deg. phase shift. The outputs are added and fed to a further adder. The outer input of this is fed from a circuit giving a function of both discriminator outputs and a measure of the rate of change of frequency. The final output feeds a proportional integral shaping network which in turn supplies the voltage to the local voltage controlled oscillator. This gives a fast response but good noise immunity.

Patent DE-2435621-A1 (DE)
Title: Transmission errors recognition method - if for isochronously binary modulated signals periodically scanned by scanning circuit
Inventor: PREY GERHARD
IPC: H04L1/20
Filed: 1974-07-24
Abstract: Scanning is controlled by clock pulses, and the signal taking over takes place only at the middle of a bit. Depending on the expected degree of distortion, the signal is divided in sections (A and B) of one type in which signal amplitude change is expected, and of a second type in which such changes must not appear; when these changes appear during second type sections, they indicate a transmission error possibly requiring signal repetition; the two different sections are determined by a series of counting states of a cyclically operating counter (AD/LOG), which controls the signal scanning and taking over; the number of scanning steps between consecutive amplitude changes is monitored, and if it is smaller than given by the expected distortion, it indicates a transmission error.
Patent DE-2436603-A1 (DE)
Title: Sulphated dextrin used as additive for concrete or mortar - improving flowability and permitting reduction of water content
IPC: C04B24/16
Filed: 1974-07-30
Abstract: Sulphated dextrin is added to concrete or mortar (pref. in an amt. of 0.1-5 wt. % w.r.t. the dry binder) as a fluidising agent. The dextrin is sulphated by known methods, pref. in a strongly polar solvent, using chloro- or amido-sulphonic acids, SOCl2, oleum, SO3 or its complexes with org. bases. The workability and densification properties of fresh concrete and mortar are greatly improved; the compsn can be cast into the moulds without application of vibrations in spite of the fact that the water content of the compsn. is reduced. The low water content causes reduction in capillary volume in concrete or mortar, and, hence, improved resistance against water penetration. The resistance again against frost, action of de-icing compsns. or other aggressive substances is improved. The additive can be used in concrete or mortar compsns. contg. as binders Portland cement or similar cements, blast furnace slag and lime.

Title: Analogue voltage to digital keying ratio convertor - has differential amplifier with feed-back
Inventor: WETZEL KLAUS ING GRAD
IPC: H03K7/08
Filed: 1974-08-16
Abstract: Amplifier output voltage depends on the difference between the two input signals. Analogue voltage UE input (5) is connected to the amplifier (1) first input (2). Its second input (3) carries a reference potential UN. Positive and negative feed-back circuits are between the amplifier (1) output (4) and second input (3). The reference potential (UN) is reduced by positive feed-back and increased by negative feed-back. Reference potential change caused by negative feed-back is greater than that caused by positive feed-back and is delayed with respect to the latter. The ratio of delays for the reference potential (UN) in both directions, up to the amplifier switching over, is proportional to the analogue voltage.

Title: Automatic speed limit warning speedometer - has external indicators for selected speed limit and horn warning if limit exceeded
Inventor: WITTENBURG WALTER
IPC: G01P1/11
Filed: 1975-05-06
Abstract: The speedometer is fitted with four sets of contacts, representing four set speed limits. One of the limits is selected by the driver, depending on which road he is travelling, and with the set limit indicated externally to the vehicle by one of the set of colour lights. This enables police, etc., to determine if the correct limit has been set. As soon as the driver exceeds the limit the vehicle horn is sounded, and is not cancelled until the speed is reduced below the limit. An interlock prevents the driver from selecting a higher limit to cancel the horn. The system relieves the police from tedious radar traps, etc.
