Title: Method for varying the physical state of liquid fuels for internal combustion engines
Inventor: KATT ANTON
IPC: F02M31/10
Filed: 1986-12-11
Abstract: The subject of the invention is a method for the preheating of liquid fuels for water-cooled internal combustion engines. The object of the invention proceeds on the assumption that a liquid fuel for internal combustion engines is correspondingly heated before passing into the carburettor or the injection pump, and thus is no longer atomised in the mixing duct of the carburettor but fed to the combustion chamber already in the carburetted state. In this, the preheater is incorporated into any line of the radiator system carrying warm water. The fuel line is in turn led through this preheater and on the way to the carburettor or to the injection pump absorbs the quantity of heat which is needed to maintain the required operating temperature of the engine. This fuel thus preheated is thereby fed into the float chamber of the carburettor or into the vacuum vessel of the injection pump.

Title: Bearing arrangement for a one-piece transverse control arm of a wheel suspension
Inventor: KRAUSE EDUARD
IPC: B60G3/06
Filed: 1987-04-01
Abstract: A bearing arrangement for a one-piece transverse control arm of a wheel suspension has two bearing brackets fixed to the body and arranged at a distance from one another, which define a swivel axis extending essentially in the vehicle longitudinal direction. The bearing bracket adjacent to the nearest end of the vehicle is arranged, in relation to the control arm joint assigned to it, on its side remote from this vehicle end and the control arm joint is over-mounted on this, whilst the other bearing bracket fixes the control arm joint supported on this on the vehicle body in the direction of the swivel axis. In the event of an impact force acting on this vehicle end, that part of the vehicle body forming the bearing base for the transverse control arm can also be deformed in order to neutralise impact energy, in that the bearing bracket serving for over-mounting the control arm can be displaced in the direction of the other bearing bracket.

Title: Desensitising explosives or propellants - comprises mixing them with desensitiser e.g. graphite dissolved in a liq. solvent, evaporating solvent etc.
Inventor: WANNINGER PAUL DIPL CHEM DR
IPC: C06B23/00
Filed: 1987-04-09
Abstract: Desensitisation of explosive (IA) or  propellant (IB) involves mixing with a desensitiser (II) in the presence of a liquid (III), removing (III) and granulation. The novelty is that (III) is a solvent for (II), in which (I) is insol. or only slightly soluble, so that  is (partly) dissolved in (III) and (I) is incorporated in the soln. (II) is a wax or plastics. (IA) is crystalline and has high brisance and pref. is added in the moist state. Graphite powder can be added to the (II) soln. and/or the mixt. of (I) and (II) (to prevent electrostatic charge). The mixt. contains min. 97 (wt.)% (I) and max 3% (II) w.r.t. dry matter. USE/ADVANTAGE - The technique is simple and relatively rapid. It is suitable for desensitising high brisance crystalline (IA), e.g. octogen (HMX), hexogen (RDX) or nitropenta, with waxes or plastics, esp. rubber e.g. Buna, fluorinated polyethylene or polyurethane.

Patent DE-3720872-A1 (DE)
Title: Tidal power station
Inventor: MEYER KURT
IPC: F03B13/26
Filed: 1987-06-24
Abstract: The invention of my tidal power station is based on the recognition of how the immense force of the tidal motions of the oceans can be converted into useful energy. For the first time, compressed air is generated in tanks anchored in the sea and stored on land in tanks, by the tidal oscillation and not the tidal stream. The advantage over conventional running-water power stations is that compressed air can be stored almost indefinitely, and discharged only when needed. I must emphasise in particular the absolute environmental friendliness of my invention compared to coal-fired and nuclear power stations. I consider our sophisticated shipyards, which are working at much less than capacity, suitable builders of my tidal power station, which could be erected all over the world.

Title: System and method for vehicle speed control
Inventor: TAKEI AKIRA
IPC: B60K31/04
Filed: 1987-07-07
Abstract: System and method for controlling vehicle speed, an opening angle of a throttle valve of a vehicle engine being controlled in such a way that it is equal to a desired opening angle, which is set in accordance with an operating variable of an accelerator element. In the system and method for controlling the vehicle speed, a setting switch is provided, upon actuation of which a command is emitted at the beginning of a vehicle driving condition at a desired speed. The vehicle speed control system learns a characteristic of the vehicle that indicates a relationship between the vehicle speed and the opening angle of the throttle valve when the vehicle is in a stable driving condition, derives an optimum opening angle for the throttle valve, at which the vehicle can be driven in accordance with the known characteristic, and controls the opening angle of the throttle valve in accordance with the optimum opening angle so that the vehicle speed corresponds to the desired vehicle speed when the optimum opening angle is greater than the desired opening angle.
Patent DE-3723332-A1 (DE)
Title: Arrangement for finding the position line or the location of a vehicle
Inventor: GOETTING JUN HANS-HEINRICH DIP
IPC: G05D1/02
Filed: 1987-07-15
Abstract: To date, driverless vehicles are guided in many areas in an inductive manner by means of a guide wire. Determining the location with respect to a guide wire is carried out with the aid of an identifying device and with so-called passive code carriers. The new method is intended to make it possible to find a position line or location by means of a passive code carrier without a guide wire, in order, ultimately, to enable driving without a guide wire. If two transmitting aerials are alternatingly operated in the identifying device and a passive code carrier is located in their operating range, the code carrier reacts, in accordance with its position, on the receiving device or devices by influencing the field, with varying strength. Assessing the reaction makes it possible, besides the identification, to find the position line. The location can be found when, in the case of a running vehicle, a position line is determined by means of at least two transmitting and one receiving aerial and finally the location is determined by means of the change with time of the reaction, or when two position lines are determined and assigned by means of at least two transmitting and two receiving aerials. Driverless transport systems.

Title: Valve timing gear for compressors, engines etc.
Inventor: MICHEL BERNHARD
IPC: F01L13/00
Filed: 1987-08-06
Abstract: Valve timing gear for compressors, engines etc. by means of a cam wheel. It is proposed that a cam wheel, rotatably mounted above a valve, in which cam wheel a cam acting essentially axially acts on the assigned valve, be improved so that different valve opening times can be set. In place of a fixed cam, an adjustable cam is proposed, which with an active surface of differing length can be brought into the circular orbit on the cam wheel with which the cam wheel slips over the valve or the assigned tappet. This cam adjustment facility results in the cam acting on the valve for a differing length of time.
