Patent DE-2657596-A1 (DE)
Inventor: KRAUSS WERNER
IPC: B01F33/40
Filed: 1976-12-18
Abstract: The mixing chamber silo has a main silo space (5) to which the material can be fed by devices (4). A pneumatic mixing chamber (6) is arranged centrally in the floor (2) of the main silo space (5), the material being fed to this mixing chamber from the annular space (10) through wall apertures (9). The flowable material then passes out of the mixing chamber (6) into a discharge chamber (11), from which it is drawn off through apertures (12). Part of the annular space (10), above the wall apertures (9), has, in vertical radial section, based on the inlet width of this part, a coefficient of fineness of 1 or more, preferably of 1.7 to 3.1. The coefficient of fineness is the quotient of the height (h) of the part of the annular space under consideration and its radial width at the inlet cross-section. Flow conditions in the annular space (10) are advantageously influenced by this measure. <IMAGE>

Title: Cupboard stored appliance positioning mechanism - has extension plate for locating appliance on top of cupboard without obstructing cupboard doors
Inventor: SCHMID GUENTER
IPC: A47B77/10
Filed: 1977-05-12
Abstract: The extension unit for moving a kitchen appliance from a storage position inside a cupboard into a work position, has a fixed part (12) which can be fastened inside the cupboard and a movable part (13) which is held on the fixed part so that it can be drawn out from its storage position beneath the worktop (18) raised up over the worktop and then moved back into its work position above the work top. The front of the movable part (12) has an angled holder (15) for the appliance (17). When the latter is in the work position, this fits closely round the front ara of the worktop so that the cupboard doors are not obstructed.

Patent DE-2723847-A1 (DE)
Title: Antiskid brake control system - has failsafe interlock which monitors relative pressures on wheels of each axle and regulates inhibit control
Inventor: LINDEMANN KLAUS
IPC: B60T8/96
Filed: 1977-05-26
Abstract: The anti skid brake control monitors the dynamic condition of the separate wheels during braking and provides brake force modulating signals at the onset of wheel lock. The relative pressures during braking, as well as the relative input and outlet pressure of the modulation valves are also monitored. If any of the pressures exceeds set limits, an inhibit control reverts the braking to normal braking. The system eliminates faulty braking due to faults in the mechanical parts of the system e.g. sticking control valves.
Patent DE-2728658-A1 (DE)
Title: Optical cable of several plastic sheathed fibres - has at least one support element stranded together with optical fibres (NL 28.12.78)
Inventor: OESTREICH ULRICH DIPL ING
IPC: G02B6/44
Filed: 1977-06-24
Abstract: The cable may contain e.g. three support elements (1), the middle one serving as central element and for relieving tension. Two glass fibres (2), each in a plastic sleeve (3), are stranded together with the other two support elements around the central element. In this way, the support elements which take up the pressure between the central element and outer sleeves protect the sleeves against deformation. Another outer sheath (5) made of solid plastic absorbs any impact or shearing stresses. The concentric glass fibres may lie on a circular ring, each between two support elements which keep away any external pressure from the sheathin. The central support element may be surrounded by a cushioning which gives a certain resilience to the cable construction.

Patent DE-2742252-A1 (DE)
Inventor: BLEICH SIMON
IPC: B26D3/10
Filed: 1977-09-20
Abstract: The angular cutter for cutting stacks comprises two elements (1a, 1b) which are releasably connected to one another and form a level inside wall (10), so that the cutouts of the stacks can move upwards along the said wall (10). The elements (1a, 1b) are ground so as to be wedge-shaped at their lower ends. In this process, the wedge surfaces (16) are, at the point of impact of the two elements (1a, 1b), ground slightly more towards the impact edge and the grinding edge than elsewhere, so that a free space is formed in the corner, to prevent the sticking of the cutout corners of thin sheets of paper in the corner of the angular cutter. <IMAGE>

Title: Electrophotographic copy prodn. from original - with one exposure using sec. renewable image obtd. from prim. image allowing formation of many copies
Inventor: NAKATSUBO TOSHIO
IPC: G03G21/00
Filed: 1978-03-07
Abstract: An electrophotographic process for the prodn. of a number of copies from a single original is claimed. From the original, a primary electrostatic latent charge image is produced on a recharging grating comprising a large number of very small holes. This grating is pref. a drum. From this primary latent charge image, a sec. electrostatic latent charge image is produced on a transfer device, pref. also a drum, composed of a charge-storing coating on an electrically conducting backing plate. This sec. latent charge image is repeatedly developed and transferred onto copying paper, thus producing a large number of copies. Many copies can be produced from a single original using only one exposure. In addn., this number of copies can be produced from only one prim. electrostatic latent charge image stored on the grating.

Patent DE-2812527-A1 (DE)
Title: Drive mechanism for rotating shaft - has weight moving radially in and out on arm projecting from shaft
Inventor: HENNINGSEN ERNST
IPC: F03G3/00
Filed: 1978-03-22
Abstract: The cylinder (20) is attached to project radially outwards from a shaft (21). It contains a piston (25) which is pushed radially out by hydraulic force against a spring (26). A rod (24) projects from the piston radially outwards and carries a weight(23). The hydraulic system is controlled to force the piston and weight out when the weight is vertically above the shaft and to allow the spring to pull them back when the weight is directly below the shaft. The weight thus exerts a larger turning moment on its downward movement than on its upward one and therefore produces rotation of the shaft.
Patent DE-2820141-A1 (DE)
Title: Frequency coder for TV camera colour signals - has red and blue phase gratings one behind other and rotated to produce colour image
Inventor: DAMMANN HANS DR
IPC: H04N9/083
Filed: 1978-05-09
Abstract: The frequency coder has a strip-like rastered phase grating structure reproducing an optical image and producing a rastered colour extract a short distance behind the raster grating. The extract produced depends on the grating constant and raster strip spacing. A grating for red light and a grating for blue light are located directly one behind the other, or can be mounted on the same support. The two gratings are rotated through an angle w.r.t. one another. The distances between strips in the gratings bear a given ratio, e.g. 3:4, to one another. The grating structure may be a binary phase structure, sinewave or step-shaped.
