Title: Sensor-controllable actuating device for guided missiles
Inventor: SUNDERMEYER PETER DR
IPC: F42B15/01
Filed: 1985-01-16
Abstract: A sensor-controllable actuating device for the control-surface shafts (7) of a guided missile is intended to be designed for a simple outlay in terms of control technology and apparatus, despite relatively stringent requirements for the operational readiness and for the navigation capabilities of the missile. For this purpose, a system which is open with respect to the positioning shaft (7) and has an actuating motor (1) in the structural form of a brushless DC motor with electronic commutation (12) is selected which, taking into account the transmission play in the transmission gear system (20) from the motor (1) to the positioning shaft (7), is driven from the autopilot (14) of the missile. A drive feedback message to the autopilot (14) in order to influence the control behaviour statically and dynamically is picked off from the electronic commutator (12). This enables costly additional rotation-angle sensors, which are susceptible to defects, on the positioning shaft (7) itself to be omitted. <IMAGE>

For the stability of the ground-hugging harrow, especially at high working speeds, there are guide elements (13) which are arranged on the comminuting elements (5), preferably the first row of comminuting elements (5) of the middle part (2). The guide elements (13) can partially project beyond the comminuting elements (5) and have a surface (15) oblique relative to the drawing direction. Connecting elements (10), which connect the middle part (2) to the drawbar (1), are preferably designed in the form of chains and are suspended releasably on the drawbar (1). For this purpose, there are hooks (17) which allow an easy suspension and removal of the connecting elements, so that a simple and rapid reversal of the ground-hugging harrow becomes possible. <IMAGE>
Patent DE-3501779-A1 (DE)
Title: Rotary piston internal combustion engine
Inventor: BOEHM ALWIN
IPC: F02B55/14
Filed: 1985-01-21
Abstract: The present invention relates to an internal combustion engine, working on the principle of the rotary piston drive, with hydrodynamic charging control. The engine is characterised by four pistons running in the same direction of rotation, which have a working chamber, which is divided into a combustion chamber, into a compression chamber and a precompression chamber with over-pressure lock and over-pressure duct. The said structuring of the working chamber results in charging unrelated to the speed. The advantages lie in improved fuel combustion, an increased thermodynamic efficiency and a low exhaust noise level. Other advantages of the rotary piston internal combustion engine are favourable rotational force behaviour due to four working strokes within one revolution and no free inertial forces.

Title: Mixing unit with two servo-controlled valves
Inventor: HONEGGER PETER OLIVER
IPC: G05D23/13
Filed: 1985-02-28
Abstract: Of the two servo-controlled valves (11,11') intended for mixing hot and cold water, one is intended for cold water and the other for hot water. Both valves (11,11'), which are arranged next to one another, each have a projecting control lever (42). Actuation is effected by means of a rocker lever (54) which acts on one control lever (42) with each of its two ends. To open and close the two valves (11,11'), the rocker lever (54) is moved in parallel with itself (116). Opening is generally effected by a manual actuation device while return is effected in a delayed manner by means of a delay device. For adjusting the mixing ratio, the rocker lever (54) is arranged in a manner which allows it to be tilted about the axis of a rod (70). For the at least approximately parallel adjustment, the rod (70) is swivelled up or down. In such a mixing unit, the two valves (11,11') serve both for the adjustment of the mixing ratio and for simultaneous opening or closure. A preferred area of application is for showers in public facilities. <IMAGE>

Title: Spanner with torque amplification
Inventor: LANGE HANS
IPC: B25B17/02
Filed: 1985-05-21
Abstract: A spanner with torque amplification consists of a transmission (7), a drive part (6), a location part (4) for a screwing tool (5), a fixed housing (2), and a supporting part which is rigidly fastened to the housing (2). The axis of the location part (4) and of its screwing tool (5) runs in alignment with the axis of the drive part (6), the transmission being formed by a basic body (13) provided with a central tapped hole (11) and rotatably mounted relative to the housing (2), a spindle (19) inserted into the tapped hole (11), a driving tube (22) rotatable relative to the housing (2) and surrounding the spindle (19), and a bolt which extends transversely to the longitudinal axis of the spindle (19) and via which the spindle is coupled to the driving tube (22). The input-side rotary movement of the drive part (6) is thus first of all transformed into an exclusively axial movement of the spindle (19), which in turn is converted again into a purely rotary movement of the driving tube (22), to which the location part (4) is rigidly fastened. The construction according to the invention not only permits simple manipulation but also a compact type of construction at a high torque transmission ratio. <IMAGE>

Patent DE-3540790-A1 (DE)
Title: Water-bed heater
Inventor: HETTMER PAUL
IPC: A47C21/04
Filed: 1985-11-16
Abstract: The object of the present invention is to provide a heater which is fitted with a shield and combines the elements heating body, temperature sensor and temperature control in one unit, thus avoiding the disadvantages. The most important feature of the water-bed heater shown in Fig. 1 is a congruent application of a metal support (1), in the form of a plate or film or of a fabric, over the flat heating body (3) facing the water bag (4), which metal support is connected via the mains cable (2) to the earth conductor and is thus earthed. In this way, the electrostatic induction phenomenon is eliminated and, additionally, when touched, no unpleasant heating of the touching part of the body can take place because the metal support (1), as a good thermal conductor, discharges any heat accumulation otherwise occurring and passes it on directly to the water located in the water bag (4) at a different location. The further feature is the combination of the heating body (3), temperature control (5) and temperature sensor (7) in one unit, only the potentiometer (6), as a relatively small construction unit, being guided out of the water bed via a cable (8) of any desired length for the temperature adjustment. In this way, faulty operation of the temperature control due to incorrect mounting of the temperature sensor is prevented. Due to the unit of the heating body (3), temperature control (5) and temperature sensor (7), annoying cable connections are omitted. The overall ... Original abstract incomplete. <IMAGE>

Abstract: An internal combustion engine as described with a zero degree angle formed by the cylinders in which the pistons actuate various cranks of a crankshaft, the bends of which are offset at an angle in relation to one another in such a way that there is a total matching of the second-order inertial forces. The angle of offset  alpha between the two cranks is 270 degrees. In a further development of the invention, two such internal combustion engines can be arranged in series to form a four-cylinder internal combustion engine. The drawing of figure 1 shows the axes of the first and second cylinders denoted as (1) and (2), which lie in one and the same plane. The pistons (3 and 4) actuate via connecting rods (5 and 6) the cranks (7 and 8) of a crankshaft, the axis of which is denoted by 9. The angle between the bends of the cranks (7 and 8) is denoted by  alpha  and is 270 degrees. The arrow (10) shows the direction of rotation of the crankshaft. Figure 2 shows a diagram of the second-order forces of inertia (P) of the first and second cylinders for the corresponding crank positions  phi  and their counterbalancing.

Title: Fluorine-containing polymer, process for the preparation thereof, and the use thereof
Inventor: WIENERS GERHARD DR
IPC: C08F20/22
Filed: 1986-01-25
Abstract: Fluorine-containing polymers can be prepared by free-radical-initiated polymerisation of corresponding fluorine-containing monomers, optionally mixed with other vinyl monomers. The polymerisation temperature depends on the decomposition temperature of the initiator. The fluorine-containing monomers used can also contain deuterium atoms. Particularly suitable monomers are those of the formula  H2C=CF-CO-O-C(CF3)-X, in which X is a hydrogen atom or a deuterium atom. The polymers have a high molecular weight, are non-crystalline and have softening points of above 100 DEG C. They are used in particular as materials for the production of transparent articles.

Additionally, an adjustable light source is arranged above the table-like support for producing at least one line of light for the marking of the position region of the small item on the transparent plate or in relation to the pattern of the large item.
Patent DE-3608325-A1 (DE)
Title: Integrated thermostatic condensation drainer
Inventor: STEIN MARCEL DIPL ING DR
IPC: F16T1/02
Filed: 1986-03-13
Abstract: The invention relates to a float-type condensation drainer with a single valve and automatic venting. During normal operation, the valve is regulated by a known float device, meanwhile a thermostatic device, without being stressed from the outside, moves freely. If the temperature drops below a specific value, the thermostatic device raises the float device in order to open the valve and to bring the float above the condensation level. The housing is thus vented and the condensation level drops below the outlet opening. Stressing of the thermostatic device at relatively high temperatures by stationary forces or vibration forces is avoided. Consequently, the service life of the same is increased considerably. Standstill corrosion of sensitive parts is prevented, this permitting the use of less expensive materials. The embodiments with total venting of the housing also ensure protection against frost and freedom from accumulation of solid particles. Influences of water hammers on the float are reduced. The invention can, in some circumstances, be used on conventional drainers.
