Title: Apparatus for producing a preferably chemically reactive mixture from at least two polymer components, in particular polyurethane
Inventor: KOENTGES GERHARD
IPC: B29B7/76
Filed: 1986-09-12
Abstract: The apparatus for producing or mixing a preferably chemically reactive mixture from at least two polymer components, in particular polyurethane, is provided with a mixing head 1 with a mixing chamber 4, which has inlet openings 5 and 6 for the individual components and an outlet opening 18 for the component mixture. Arranged in the mixing chamber 4 is an ejecting piston 3, which is of the same diameter as the said mixing chamber, is connected to a pressure-medium-operable working piston 2 and can be moved back and forth out of a mixing position, exposing the inlet openings, into the region of the outlet opening. As it does so, it closes off the inlet openings with respect to the mixing chamber. Furthermore, a directional valve is provided for controlling the pressure medium for the working piston. Since the movement of the working piston and of the ejecting piston connected to it is opposed by mechanical and adhesive forces, this movement does not take place in an exactly reproducible way. To achieve a high accuracy of reproduction with regard to the amount to be mixed, there is provided for the working piston a displacement sensor 9, which controls the directional valve 13 on the basis of a setpoint input. It is thus precisely determined whether the working piston, and consequently the ejecting piston, have commenced their movement at all and what displacement has been made, i.e. the speed at which the pistons are moving. In dependence on the setpoint input, then, by influencing the directional valve ...   Original abstract incomplete. <IMAGE>

Patent DE-3636840-A1 (DE)
Title: Toy car
Inventor: HANZAWA TSUNEO
IPC: A63H17/26
Filed: 1986-10-29
Abstract: The invention relates to a rear-wheel-drive toy car in which a transversely extending panel similar to a spoiler is arranged above the rear of the vehicle and extends laterally beyond the outer limit of the rear wheels so that, if the car turns over sideways, at least one of the rear, driven wheels remains in contact with the ground and thus, with the aid of the position of the central gravity of the toy car, the vehicle can fall back again into its normal position. The same purpose is served by a resilient wire projecting from the rear part of the car, if possible eccentrically, which resembles a car radio aerial and, in the event of a frontal collision of the car with an obstacle and its consequent standing on end, prevents the toy car from turning over backwards so that again at least one of the driven wheels remains in contact with the ground and automatic returning of the toy car into the normal position is possible.

Title: Process for producing foamed fruit, vegetable or spice dishes
Inventor: ALBERSMANN HEINZ
IPC: A23L1/00
Filed: 1986-11-12
Abstract: Such foamed dishes, such as fruit yoghurt, ice cream, crèmes or the like, which are used as desserts, garnish or for direct consumption, in addition to the fruits, usually contain fats, protein and sugar in order to obtain a relatively stable structure; they are therefore highly nutritious and also poorly digestible. To produce low-calorie (reduced-calorie) foamed fruit dishes without fat and protein which, in addition to the above listed uses, are used as flavour-enhancing, volume-increasing or decorative top or intermediate layers, or are considered in fabricated form for consumption between meals, in addition to the related fruit base materials, sugars or sugar substitutes or sweeteners, spices or fruit extracts or the like in appropriate quantities, hydrocolloid combinations and emulsifiers suitable for achieving a high stable foaming are added.
Patent DE-3639129-A1 (DE)
Title: Climbing bracket
IPC: E04G5/06
Filed: 1986-11-15
Abstract: On suspending known climbing brackets on hooks on structures, they often have to be displaced by hand in order to acheive a precise position parallel to the walls, this being very laborious and, in an unsecured state, also relatively dangerous. By means of the newly proposed configuration, the building crane can achieve a precise positioning, without corrective work by hand, as early as on suspension of the climbing bracket. A precise, automatic positioning of the climbing bracket (1) can be achieved in that at least one of the hook-receiving means is configured in the form of a collecting funnel (5), which widens downwards in the form of a funnel, and the mouth opening (8) is considerably greater than the associated hook (7) which is to be inserted. The proposed climbing-bracket configuration permits precise positioning with respect to the structure wall as early as on suspension of said bracket, without corrective work by hand. <IMAGE>

Patent DE-3727454-A1 (DE)
Title: Method of manufacturing ribbed tubes
Inventor: BIEDERER HANS HERMANN DIPL ING
IPC: B23K1/00
Filed: 1987-08-18
Abstract: To achieve the heat transfer properties demanded, it is essential in the manufacture of ribbed tubes that the core tube is metallically firmly connected to the peripheral helical rib strip. To this end, it has hitherto been necessary to first of all coat either the core tube and/or the rib helix with soldering tin in a separate pretreatment step. The soldering tin melts due to the heating of the ribbed tube and after the cooling connects the core tube and the rib helix to one another. The method according to the invention starts from an uncoated core tube, on the surface of which an uncoated rib helix is wound. A suitable soldering paste is then specifically applied in the area of the contact line between the core-tube surface and the longitudinal edge of the rib helix. The core tube and the rib helix are then firmly connected to each other metallically, for example by brief inductive heating. Soft-solder and brazing pastes or pastes with neutral resin fluxes are used as the soldering paste.

Filed: 1987-12-11
Abstract: Method for feeding granular feed material, in particular sand, to an impact mill which has at least once the number a of beaters which are fastened on a shaft in a radial plane and are arranged at equal angular distances from one another. The shaft is driven at a frequency of n rotations per second. The feed material is introduced, with the aid of a vibrating conveyor, via a free fall section s into the working region of the beaters of the impact mill. The vibrating conveyor is driven at a frequency of w vibrations per second. It discharges the feed material in w feed material part flows. The frequency w of the vibrating conveyor is selected so as to be greater by the factor a than the frequency n of the shaft (w = a n). The vibration of the vibrating conveyor is operated, with respect to the movement of the shaft, with a phase relationship which depends on the free fall section s and ensures that in each case a beater meets a feed material part flow. <IMAGE>
Patent DE-3744340-A1 (DE)
Inventor: IIZUMI TOMOO
IPC: G11B19/04
Filed: 1987-12-28
Abstract: Accidental erasure of servo tracks on a disc is prevented by providing on the other face of the disc, or on the face of an associated disc, an unrecorded region in a position corresponding to the servo tracks. Lack of signal from the unrecorded region concurrent with read out from the servo tracks acts to bar the write function. The use of a corresponding unrecorded region may be used to indicate when the heads are aligned with an outer guard band having recorded signal. Since all other corresponding regions produce concurrent signal read out the write function is available in those regions.
