Patent DE-3033655-A1 (DE)
Title: Isobutyric acid or its lower alkyl ester cpds. continuous prodn. - by Koch process from propylene, carbon mon:oxide and water using short dwell time
Inventor: BESECKE SIEGMUND DIPL CHEM DR
IPC: C07C67/38
Filed: 1980-09-06
Abstract: Prodn. of isobutyric acid (IA) or its lower alkyl esters (IB) by the Koch's synthesis involves the one-stage reaction of C3H6, CO and H2O or a lower alcohol, opt. (partly) replaced by their adducts, in the presence of HF as catalyst. The novel feature is that the starting materials are reacted continuously, with high remixing, at 80-160 deg.C, the dwell time of the liquid phase being under 20 min., so that the content of C3H6 or the isopropyl formate used as adduct in the reacting mixt. is under 1 wt.% w.r.t. the liquid phase. The water or alcohol (MeOH) content is kept below 5 (below 2) mole-%. The total pressure is 50-150 bar, temp. 100-140 deg.C and dwell time of the liquid phase 2-10 min. The amt. of HF used is 5-15 mole/mole C3H6. The water or alcohol and C3H6 are supplied continuously in (0.9-1.1):1 molar ratio and the CO and C3H6 are mixed in the gas phase. Reaction is carried out in a gas-liquid reactor with dispersed gas phase. (I) can be dehydrogenated to methacrylic acid or its esters, which are starting materials for valuable plastics. High yields and selectivity are attained and the oligomer problem is minimised, whilst the throughput is high and the dwell time short.
Patent DE-3042381-A1 (DE)
Title: Solid fuel fireplace with boiler - has concave dome for reflecting heat and boiler wall
Inventor: FIEGENBAUM DIETER
IPC: F24H1/24
Filed: 1980-11-10
Abstract: The equipment makes maximum use of the heat energy in solid fuels, having a concave dome (6) and boiler wall (7) for the combustion gases. The boiler wall forms part of a water jacket, and acts as a heat-exchanger in conjunction with the dome and the baseplate. The concave formation of the internal chamber reflects heat radiation and deflects the combustion gases, thus automatically causing after-burning at the focal point. This can be further aided by a deflector plate (1) mounted inside the dome. A cowl (4) can also be mounted over the fireplace, to prevent smoke emerging into the room.
Patent DE-3048534-A1 (DE)
Title: Reflex viewfinder for weapon sights - controls electronic display constructed of LED or LCD elements to select optimum target markings in dependence on target characteristics

Filed: 1980-12-22
Abstract: The reflex view finder uses an electronic display controlled in dependence on data relating to the distance and movement of the target, so that only the optimal target marking is visible via the viewfinder. The electronic display may comprise an LED matrix or liquid crystal display cell, controlled via a microprocessor receiving the target data. Pref. the electronic display (50) has 10 distance steps (52) each with a corresponding light point (53) cooperating with a cross-wire aiming device (51). Further information, e.g. the effective target distance may be indicated below the target markings. The viewfinder is used for an anti-tank gun.

Title: Apparatus for the production of a yarn
Inventor: FEHRER ERNST DR
IPC: D01H4/16
Filed: 1981-02-12
Abstract: An apparatus for the production of a yarn consists of two suction drums which are located closely next to one another and rotate in the same direction and the suction inserts of which have inflow orifices which extend along the yarn-forming line in the gusset region between the two suction drums and which are located opposite one another in relation to the yarn and generate a suction flow drawing the yarn into the gusset region between the drums, and of a guide channel projecting into the gusset region and opening out in the region of the suction zones. For the direct tying of the enveloping fibres into the composite yarn structure, the clear width of the inflow orifices (3) of the suction inserts (2), as measured in the direction of the drum circumference, corresponds to four to ten times the yarn diameter. <IMAGE>

Patent DE-3126978-A1 (DE)
Title: Electronic timer (timepiece) having an improved response of the primary frequency divider
Inventor: SEKIYA FUKU
IPC: G04G19/06
Filed: 1981-07-08
Abstract: An electronic timer has a primary frequency divider circuit (13) which receives a standard frequency signal and consists of a group of p-channel FETs and a group of n-channel FETs. A biasing circuit (54) applies a bias input signal to the p-channel FET group and a separate bias input signal to the n-channel FET group. These bias input signals are generated by a current mirror coupling from a standard current source (10), with the result that the response of the primary frequency divider circuit (13) to low amplitudes of the standard frequency signal can be made over a wide range of battery voltages virtually independently of variations in the battery voltage of the timer. <IMAGE>

Title: Fastening of a casing of a roller blind, a slatted blind or the like, preferably an anti-insect grille which can be rolled up, on a fastening surface carrying the casing
Inventor: BADEWIEN REINHARD
IPC: E06B9/17
Filed: 1981-09-10
Abstract: The invention relates to the fastening of a casing of a roller blind, a slatted blind, an anti-insect grille or the like, the rolled-up roll of which is retained in the casing. The casing is fastened on fastening surfaces, e.g. a window frame, above a building opening which is to be covered. The fastening according to the invention takes place by suspending the casing on retaining fittings. Each retaining fitting, which can be screwed onto the fastening surface, has, in addition to a shaped piece into which the casing can be hung, a locking piece into which a latching element of the casing can be pressed and thus secures and locks the suspended casing with respect to the movements in the vertical plane which are a source of risk to the suspension.

Title: Dip tube for cyclone
Inventor: SCHMIDT PAUL PROF DR ING
IPC: B04C5/13
Filed: 1982-06-23
Abstract: Problems in separating particles from gases or liquids are the low precision of separation, especially spattered grains, and the high pressure loss. It is proposed as a solution that the dip tube, having a spiral cross-section and a helical inlet edge and extending over the whole length of the separator space, be assembled from annular pieces or helical shells, and that the enlargement of the diffuser-like slot be variable. Furthermore, it is envisaged to connect the dip tube as an electrode. The principal use is for separating dust from hot gases and sifting. The accompanying drawing shows in Fig. 1 the dip tube (1) and the cyclone (2) with inlet (3); Fig. 2 shows the diffuser-like slot which has a variable course. Fig. 3 shows a dip tube, assembled from two helical shells (5), with the connecting seam (6). Fig. 4 shows a dip tube, consisting of annular pieces (7), with deflecting vanes (9). <IMAGE>

Title: External/internal mirror for private cars for the purpose of explicitly mirroring the so-called "blind spot"
Inventor: BRAUNHOLZ GERT
IPC: B60R1/08
Filed: 1982-06-25
Abstract: The external/internal mirror serves for explicitly mirroring the so-called "blind spot" in road traffic in the sphere of private cars. The internal mirror, which is to be protected by patent, of the joint external/internal mirror is intended explicitly to mirror the small region which is not covered by the previously conventional external mirror and the previously conventional, separately mounted, internal mirror, that is to say the region in which the overtaking vehicle is level with the end of the vehicle that is to be overtaken. The advantage of the external/internal mirror as compared to the versions to date - internal panorama mirror or the angled glass surfaces in the external mirror or external panorama mirror - resides in the undistorted reproduction of the overtaking vehicle.

Title: Using tidal energy by means of bulb turbines in tidal inlets
Inventor: EICKMANN BODO DR ING
IPC: F03B13/26
Filed: 1982-06-22
Abstract: The flowing out and in of the ebb and flood streams takes place principally through the so-called tidal inlets, which are washed out like small river valleys by the said ocean currents. It is the object of the invention to use flowing water in these cases as well, for example to obtain electrical energy, use of the known method of reversible turbine blades, for example, enabling drive in both directions. The corresponding switchover is to be performed by reversing the stream itself, as an example, and compensating interaction with wind power installations on land is also considered.
