Patent DE-2613608-A1 (DE)
Title: Single-channel air conditioning for rail vehicles - uses air temperature controlled switch-over flap to direct air into upward extending outlet shaft (OE150576)
Inventor: ENGEL IGNAZ ING
IPC: F24F11/76
Filed: 1976-03-30
Abstract: The single channel air conditioning is for rail vechicles, and has an air-charged conditioning unit, and a distribution channel, extending from it. The distribution channel is temperature-controlled by an external thermostat. The channel has an associated outlet unit in each passenger compartment, with outlets below the window and seats. The outlet unit has an intermediate housing, charged with a part flow from the distribution channel, and connectable to an outlet shaft extending upwards to a window. The housing has a thermostatically controlled switch-over flap, to determine the air distribution. The flap (16) is controlled in direct dependence upon the air temperature in the intermediate housing (4), so that with a temperature above a certain pre-determined level, it frees the outlet apertures (2) below the seals (1).
Patent DE-2620796-A1 (DE)
Title: Connection of a pipe to a precast concrete ring manhole - by expanding flexible junction tube to seal in hole in manhole wall
Inventor: ROSSBOROUGH JOHN CAMERON
IPC: F16L41/08
Filed: 1976-05-11
Abstract: The process for connecting a drainage pipe into a precast concrete ring manhole, entails placing a flexible junction tube with peripheral tolerance in a hole fashioned in the manhole wall, subjecting this junction to a radial expansion until it bears hermetically on the hole periphery, maintaining it in this position via internal clamping, and finally clamping it onto the pipe exterior. The hole in the manhole wall is drilled, and of greater diameter than the pipe, and centred on a reference point which lies on the longitudinal axis of the incoming pipe. Pref. the pipe extends into the wall opening, and radial expansion of the junction is effected by expanding an internal clamping collar against its inner walls. The collar is expanded radially by an hydraulic unit exerting pressures of at least 70 kg/cm2.

Title: Countersunk fitment for built-in furniture systems - has bearing bolts with spacers for compensating different width while using same tools
Inventor: KNEILE KARL
IPC: A47B46/00
Filed: 1976-05-15
Abstract: The countersunk fitment for appts. supports in built-in kitchen units etc. includes two resiliently weight-balanced parallelogram rod systems which are mounted on side supports by means of bearing bolts (7) having spacers whose end faces - directed away from the guide rods (2, 3) and (2A, 3A) - lie directly adjoining the plane of the contact faces of the associated side supports (1, 1A). The use of such bearing bolts means that all the side supports can have the same design for any width of fitment thereby allowing the same tools to be used for mfg. fitments having reduced width differences. The spacers can easily be made in different lengths simply by cutting rod or tubular material to the required length.

Title: Material analysis photometer with moving filter system - uses filters to compensate for dirty optics or absorbent foreign substances in sample
Inventor: FABINSKI WALTER ING GRAD
IPC: G01N21/3518
Filed: 1976-10-15
Abstract: Material analysis photometer has a movable filter system to direct a beam through a sample. The beam is attenuated by the concentration of substances being detected and passes to a receiver connected to an electrical analysing circuit. A beam is produced having a spectral range corresponding to the spectral absorption of the substances to be detected. The filter system (8, 9) periodically moves a filter having spectral absorption corresponding to that of the substances into the beam path, and the analysing circuit forms the quotient of the two components of the received signal produced by the filter system.

Title: Paving stone run=up ramp - comprises row of stones with top edge sloped relative to roadway
Inventor: ERNST HERBERT
IPC: E01C11/22
Filed: 1976-10-23
Abstract: The approach ramp to a curbstone, or similar elevation, is designed to facilitate negotiation by a vehicle from the road, and to reduce wear on the curbstone. This involves a series of stones or blocks arranged close together in a row. The top edge of these is inclined relative to the roadway. Each of these ramp stones may have its top edge rounded off; or each top edge may be arched in a convex or concave shape.

IPC: G03F7/20
Filed: 1977-01-31
Abstract: Arranged on a first optical axis (A-A) are a light source (1), an aperture stop (5) a field lens (6) and a further lens (7). Arranged on a second optical axis (B-B) offset parallel to the first are an object field lens (10), a transparent carrier (11) with a master division (12), a projection lens (13) and a division carrier (14) with a photosensitive layer (15). The illuminated field (8) of the light source (1) is projected with approximately four-fold magnification at the location of the field lens (6) with the aid of a concave mirror (3) and of the condenser (2). Together with the further lens (7) and the object field lens (10) the field lens (6) projects the opening of the condenser as a homogeneous light field into the master division. Together with the object field lens (10), the further lens (7) projects the intermediate image of the illuminated field into the exit pupil of the projection lens (13). The illuminating device is mounted capable of rotation about the second optical axis, and projects the illuminated field centrally into the entrance pupil in any position. A constant circular movement of the illuminating device is used to achieve a uniform illumination of the photosensitive layer (15). <IMAGE>

Patent DE-2746225-A1 (DE)
Inventor: BERNER GIANNI DR
IPC: C25D11/26
Filed: 1977-10-14
Abstract: A description is given of a process for producing high-quality local anodic oxide layers for components produced using thin-film technology. After the application of valve metal (2), for example tantalum, to a substrate (1), a first oxide layer (3) about 50  ANGSTROM  thick is applied over the entire surface of the valve-metal layer (2). This first oxide layer (3) serves as protective layer for the regions (8) to be locally anodically oxidised later. In the subsequent patterning (delineation) processes, the first oxide layer (3) must therefore remain intact at the points at which the anodic oxidation is carried out later. The local anodic oxidation can then be carried out without removing the 50  ANGSTROM  thick first oxide layer (protective layer). <IMAGE>

Filed: 1978-05-11
Abstract: To produce such a foil, one surface of a backing foil (1) is blasted with steel balls, depressions (2) distributed evenly over the surface being produced, whose depth and diameter are kept equal as far as possible. A layer of nickel (5) is applied by electroplating on the surface thus formed. A foil is thus obtained which has the same properties as a solid nickel foil, but at far less expenditure. The foil is used on the circumferential surface of printing machine cylinders to prevent smearing of a freshly printed sheet. <IMAGE>

Title: Hard-wearing tools for textile prodn. processes - produced by boriding or similar treatment of selected areas
Inventor: ZOCHER JOSEF
IPC: D05B85/04
Filed: 1978-09-01
Abstract: Mfr. of cutting, piercing, holding or transporting tools, partic. needles used in textile mfg. processes, having a hard, wear-resistant surface layer in selected areas, comprises forming a protective surface layer by diffusion into the surface of an element from Gp. 3 or Gp. 6a, to give an inter-metallic phase with a hardness superior to that of the base material itself. The method is esp. a bording process, which produces a boride layer of 5-60 mu m thickness on a substrate of low-carbon steel, which undergoes further, subsequent thermochemical tempering processes to produce desired elastic properties in different areas of the tool. Tools produced have a long working life, and give prods. of a consistently high quality, leading to better prodn. economics despite higher tool prodn. costs.
