Title: Speed control of recording instrument chart - using test grid applied to chart for scanning and spacing of lines in accordance with nominal valve comparison
Inventor: WALLNER FRANZ DR ING
IPC: G01D15/26
Filed: 1976-08-12
Abstract: The speed control device maintains the preset speed of a chart time scale constant. A test raster is applied on the chart, whose lines are perpendicular to the chart direction of movement. Spacing of the lines is in a rigid relation to the chart time scale. Raster lines are scanned by a sensor, and spacing of lines detected by the scanner is compared with a preset nominal value. In the case of a discrepancy, speed of the chart is readjusted. The drive motor revolutions can be continuously influenced by a stepped control arrangement using analogue actual values derived from impulse trains delivered from the sensor.

Title: Testing of semi-finished rolled products - uses TV cameras to scan two surface areas of product and provide signals for evaluation
Inventor: KRAMER GERHARD
IPC: G01N21/89
Filed: 1976-11-24
Abstract: The semi-finished rolled products are tested for faults which contrast with the rest of the product surface, or are made to contrast with it. At least two surface areas of the product are scanned by t.v. cameras, while the cameras move parallel to the product surface, with the video picture lines perpendicular to the direction of the relative motion. A group of lines is combined into a picture section, and video signals contained in this picture section are evaluated as fault signals. Picture sections provided for the individual t.v. cameras are produced at different time intervals, and consecutively evaluated by a common evaluation device.

Title: High-energy crystalline explosives - using polyurethane desensitising agent to coat the granules
IPC: C06B45/24
Filed: 1977-03-08
Abstract: Crystalline high-energy explosives, esp. hexogen or octogen are described in which the individual granules are coated with a polyurethane as densensitising agent. Used for casting of explosive charges, esp. hollow charges, from mixts. of high energy explosive and less brisant explosive, e.g. T.N.T. The polyurethane retains some elasticity after hardening and shows better adhesion to the granules than polyester coatings. The polyurethane m.pt. or decompsn. pt. is well above the temp. to which the charge is exposed during mfr. or use. It reduces sensitivity of the charge to shot or cracking in the field and ensures absolute homogeneity, giving increase in explosive force and efficiency.

Title: Heat-insulating plastics hard foam panels - prepd. by forming impermeable skin on one surface during cutting of panel and not requiring additional vapour barrier
IPC: E04C2/20
Filed: 1977-03-17
Abstract: Mfr. of heat-insulating plastics (esp. polystyrene hard foam) construction panels, which do not require additional vapour barriers to prevent the foam from gradually absorbing atmospheric humidity and condesnation which would eventually nullify its heat-insulating efficiency is claimed. That face of the intended panel which would normally require an additional vapour barrier, is cut so that the plastic material which is melts during the cutting step oweing to frictional heat, forms a vapour-impermeable "skin" on that face. The "cold" faces fo the panel are cut so that the structure of the material is opened (sic) for unhindered diffusing-out of water vapour.

Title: Powdered glassy carbon prodn. - by pyrolysing a mixt. of a (meth)acrylamide! (co)polymer and a water soluble salt
Inventor: BITZER DIETHELM DIPL CHEM DR R
IPC: C04B33/13
Filed: 1977-04-25
Abstract: Powdered glassy carbon is made by pyrolysing non-ionic cationic or anionic (meth) acrylamide (co)polymers in admixture with water soluble salts at 40-1600 degrees C, opt. after pre-hardening teh resin. Process is simple to operate and gives powdered glassy carbon, which is normally difficult to obtain due to the hardness of the glassy carbon (microhardness 150-200 Vickers). The prods. are useful for the prodn. of ceramic bodies; as abrasives; as fillers in tyres to increase the skid resistance; and as fillers in polyacrylonitrile fibres or viscose fibres which on pyrolysis give carbon fibres with increased rigidity.

Title: Roller mountings for rotary furnaces - using flexible layer between the mounting and the foundation allowing roller to stay in line with furnace cylinder
Inventor: FINK FERDINAND DIPL ING DR MON
IPC: F16C13/04

Title: Heat pump driven by IC engine - uses engine exhaust to prevent frost formation on heat pump evaporator
Inventor: SCHMITZ GEORG
IPC: F25B27/00
Filed: 1978-02-04
Abstract: A heat pump (2) has a condenser (4) an expansion valve (5) an evaporator (6) and a compressor (3).
