Title: Video signal detector cct. - video signal source is connected through RC cct. to first transistor amplifying stage
Inventor: KOUBEK MICHAEL
IPC: G11B27/36
Filed: 1973-09-19
Abstract: The video signal synchronisation pulses appear at amplifying stage output. A second transistor amplifying stage is connected through a further RC circuit. Synchronisation pulses appear at its output with opposite polarity. Outputs of these amplifying stages are connected through a resistor each to the base of a switching transistor, whose emitter is earthed and collector connected to the circuit output. When a video signal is present, the two amplifying stages are alternately blocked, so that the switching transistor is always conducting. When the video signal is absent, both amplifying stages are conducting and the switching transistor is always blocked.

Title: Hydraulic bolt tensioning mechanism - pulls on nut to allow insertion of distance pieces underneath it
IPC: F16B43/00
Filed: 1973-11-13
Abstract: The mechanism pre-loads a bolt with nut against a component, having a ram engaging with the bolt end and bearing against the component so as to pull the bolt away from the latter. A nut is attached to the moving portion of the ram and screws onto the bolt end, remaining on it when the ram is removed. Distance pieces are inserted between nut and component, their effective thickness being selected to match the ram stroke.

Title: Indoor space heating system armature - has electric heating element near expansion member connected to voltage source
Inventor: ROBIONEK HANS-JOACHIM
IPC: G05D23/30
Filed: 1974-02-13
Abstract: In conjunction with a thermostatic heating-body valve, used in systems for heating buildings or rooms, there is an expansion member, to which is attached a regulating piston, or other regulating member, acting on the valve cone, and the valve is normally difficult to operate the most convenient times for heating offices or other spaces, where nobody is present until the morning, thus resulting in delayed heating. Fitting an electric heating element, connected to a voltage source, in the are of the expansion chamber, such as an ohmic resistance, makes automatic or manual adjustment easier. There may be a switch for switching the heating element on and off, and elements and/or switch may be fitted in the heating-body valve. The heating element may be fitted to a temp. sensor outside the armature.

Title: Jamming device on aircraft - is used for combatting radar controlled antiaircraft weapons with laser rangefinder
Inventor: LANG MANFRED DIPL ING DR
IPC: G01S17/02
Filed: 1974-02-20
Abstract: The interval between the first and second pulse emitted by the ground laster towards the aircraft is determined by a computer on board the aircraft and is used to trigger a signal which sets off a laser on board in such a way that at the third pulse the laser on board emits an interference pulse towards the ground laser and every other interference pulse is delayed in relation to the following pulse from the ground laser. A laser warning receiver provided for the pulses from the ground laser can be coupled to a laser transmitter emitting the interference pulses and equipped with an optical system.

Title: Slicing dicing or strip cutting machine - with manual or motorised drive, for vegetables or meat
Inventor: SEIFERT FRITZ
IPC: B26D3/18
Filed: 1974-04-20
Abstract: Meat or vegetable cutter comprises a rotary cutting disc, and a support wheel to which the meat or vegetables are attached by means of a retaining member and which performs a quarter turn on rotation of the cutting disc. Adjustment of the row of blades to a new position allows double cutting depth while the blade of the cutting disc cuts in a perpendicular direction. A lever is operated to adjust the row of blades to a position which is normal cutting depth or to a position which is no cutting depth at all, to produce slices. The support wheel is mounted tiltably on a rail which is readily displaced by four balls in a housing.

Title: Compensation network for estimating inaccessible analogue variables - compensates for nonlinear characteristics of output subsystem
Inventor: LUTTMANN ALWIN DIPL ING
IPC: H03F1/08
Filed: 1974-06-22
Abstract: A compensation network is used for estimating an inaccessible state variable which can be examined only via a non linear measurement of transmission system. Such a network is applicable to analogue problems associated typically with biological and medical problems. Basically the circuit consists of a linear broadband amplifier with two feedback paths. In one feedback path a further amplifier with a gain equal to the reciprocal of the first amplifier is mounted. In the second feedback path a further amplifier with a frequency characteristic equal to that of the system to be compensated for is mounted. The transfer function of this arrangement shows that the whole network compensates for an output subsystem in the manner required.

Title: Sizing tool for cold rolling tube mill - has double tapered inner tool for expansion and good bore finish
Inventor: WUENSCHE JOACHIM
IPC: B21B21/00
Filed: 1975-05-14
Abstract: The sizing rolling tools are used for cold rolling of tubes on a pilger step by step type seamless tube rolling mill. The toll system is designed to ensure good surface finish in the bores of tubes even in the case of extensive reduction of tube diameters and wall thicknesses. The inner tool has a number of sections with different taper angles. The tapered inner tool diameter increases towards the increasing diameter of another section so that a bulge is formed in the inner tool for increasing the bore of the tube. The ellipticity of the external tool is greater in the region of the first taper B than in the region of the second taper A. The outside diameter of the tube is only slightly reduced in the region of the first taper.
