Patent DE-2810572-A1 (DE)
Inventor: ROTH WALTER
IPC: H05K7/14
Filed: 1978-03-11
Abstract: The mounting rack into which plug-in assemblies (for example electronics) can be inserted and withdrawn therefrom has upper and lower locking rails (4, 5), which have no screw connections, on its front. These locking rails, which are provided for securing the position of the plug-in assemblies, are at the same time used as covering rails for screw connections etc. and as marking rails. In contrast to previous locking rails, which are firmly screwed to the frame of the mounting rack, the locking rails (4, 5) are supported such that they can pivot at both ends (11, 12) in guides (7) on the inner end of the supporting element (1) of the mounting rack. This support is simple to manufacture. It enables rapid and simple conversion of the locking rail from the locking position into the non-locking position and vice versa. Using such locking rails, smooth front surfaces can be designed on the mounting rack. <IMAGE>

Title: Energy consumption measurement for heating plant - involves monitoring burner ON and OFF periods with and without exhaust valve control
Inventor: KAESSMANN GUSTAV DIPL ING
IPC: G01K17/06
Filed: 1978-05-02

Title: Permanent store programming before storage of binary value - applies programming signal of specified duration to storage location and uses test interval to control duration length
Inventor: HEITMANN JUERGEN DR ING
IPC: G11C16/10
Filed: 1978-09-15
Abstract: Binary values can be stored and/or modified in storage locations by programming signals. A programming signal (PR) allocated to the binary value is applied to the storage location in which it is just to be written. A test time interval (T1) is determined by reading the storage location contents, after which the binary value is stored in the storage location. Total duration (T2) of the programming signal (PR) necessary for the long term storage of the binary value depends on the test time interval.

Title: Wire coil transporter mechanism - tips into horizontal position and initially compresses on hanger truck hook
Inventor: BRAUER HANS
IPC: B21C47/24
Filed: 1978-09-30
Abstract: The mechanism transports unbound wire coils, particularly those weighing 10,000 Newton or more, from a coiling station to a compression and binding station. Driven coil transport trucks travel and stop independently along a hanger conveyor, the coils remaining suspended from them during transport, compression and binding. The coiling station has a mechanism tilting the coils, formed in the vertical position, into the horizontal one, and thrusting them onto the horizontal shanks of C-shaped hooks on the trucks. This mechanism also initially compresses the coils as it thrusts them onto the hooks. Each hook has a vertical rear stop face for the coil, and is held as the coil is thrust home and compressed.

Title: Measuring separations of points in raster image - by deriving orthogonal separation components from line-image sweep signals
Inventor: KNOCHE JOCHEM DIPL ING
IPC: G01R13/30
Filed: 1979-03-14
Abstract: A measuring device is for the distance between two or more measurement points in the line image of an image display operating with raster images generated by line and image sweep generators. The vertical and horizontal separation coordinate distances are derived as proportional signals from the image and line sweep signals used to generate the image. The actual line sweep and image swwp voltages for each measurement point are determined depending on their times of occurrence. The two successive separation distance components are determined from the time interval. Difference values derived from actual values are squared and summed to provide the square of the point separation. The diference values may be derived by subtraction or integration over the separation integral.

Title: Tyre for undriven wheel of heavy goods vehicle - has transverse slits extending half-way across outer tread bands
Inventor: WALL KLAUS VON DER
IPC: B60C11/12
Filed: 1979-05-05
Abstract: Outer circumferential bands at each side of the tread of a tyre for the undriven wheels of a heavy goods vehicle, have a series of fine, transversely running slits. These are between 0.8 and 2 mm wide, are spaced out between 2 and 12 mm apart, extend over 40% to 80% of the breadth of the bnad, have the same depth as the broad grooves between the bands and diminish gradually in depth at their ends towards the centre of the tread. When the broad grooves run zigzag, the length of the slits corresponds so that the circumferential zone has a uniform width. Arrangement eliminateds the 'washing away' of the edges of the tread and makes for much more uniform wear.
