Patent DE-2951989-A1 (DE)
Title: Figured pile effect produced by profiled cropping roller - with relief depth and sharpness controlled by fabric tension
Inventor: SCHROERS FRANZ-JOSEF
IPC: D06C23/02
Filed: 1979-12-22
Abstract: Cropping machine for producing a figured pile effect has a profiled support roller below the cropping head over which the fabric can be drawn at varying longitudinal tensions to vary the relief depth and the sharpness of the contours. The profiled roller is mounted in end bearings and supported against the tension of the fabric by a series of support rollers which can be individually adjusted for vertical and horizontal position on the mounting bar which is itself adjustable to allow the setting of the entire assembly to be varied. The fabric is passed over the roller between a feed roller and a variable-speed delivery roller, whereby the tension in the fabric as it passes the profiled roller can be varied. A high tension draws the fabric into the bottom of the pattern depressions, permitting only the pile atop the wide sections to be cropped, giving a high relief with sharp contours. As the tension is progressively relaxed, the fabric conforms less and less well to the shape of the pattern roller, the pattern relief decreases, and the contours become less well-defined. This arrangement improves the versatility of the process by enabling a variety of effects to be produced with a single profiled roller.

Title: Universal electronic time switch - has pulse generator supplying up-down counter and comparator delivering switching impulse when count is at zero
IPC: G04F1/00
Filed: 1980-03-11
Abstract: The pulses from a timing pulse generator are fed to the input terminals of a counter via a switch-operated interrupter. The counter uses a transmission corresp. to minutes and hours to count the pulses. The indicator shows the stage of count. The counter is an up-down counter that counts the timing pulses backwards. A counting state corresp. to the desired running time of the time switch can be set by a control element. A comparator delivers a switching impulse to operate a switching arrangement when the state of count is at nought. A memory can be provided for repeating a set running time. This time switch has wide application, e.g. for a cooking oven when the time scale is likely to be in hours and an enlarger concerned more with minutes and seconds.

Title: Telephone exchange reacting when called subscriber is engaged - reconnects incoming calls with facility for reminding subscriber of waiting incoming calls
Inventor: FREYMADL GEORG DIPL ING
IPC: H04Q3/00
Filed: 1980-07-17
Abstract: The special facilities of the electronic exchange are reconnection of incoming calls to another number at the request of the subscriber, and also temporary suspension of incoming calls. Both facilities advise a caller of the conditions in force. If, having selected one or other of these modes, the subscriber then places a call or, alternatively accepts a call, the automatic exchange equipment takes not of the condition. Should an incoming call arrive whilst the subscriber is thus engaged the response of the system is altered. For example, if reconnection has been selected then the call is not so dealt with. Instead a tone signal is superimposed on the subscribers receiver to remind him that reconnection has been suspended and that an incoming call is waiting.
Patent DE-3029388-A1 (DE)
Title: Multiple copying process - by toning a latent image in magnetic field with a magnetic toner and transferring the image to a registration sheet
Inventor: NOMURA MASAAKI
IPC: G03G19/00
Filed: 1980-08-01
Abstract: Copying process comprises forming an image element consisting of a non-magnetic substrate material carrying a latent image of a material with a higher magnetic permeability than the substrate. A magnetic toner is then deposited on the latent image whilst the element is situated in a magnetic field. The magnetic toner image is then transferred to a registration sheet. The toning and transfer stages are then repeated to produce the required number of copies. Pref. the image element is produced by electrophotographic means in which a photoconductive substrate is exposed imagewise and the resulting latent image is toned with a material having a higher magnetic permeability than the photoconductive substrate. Alternatively, the element can be made by heating and fusing the image areas of the substrate material, which carries a supercooled material, and the powder of higher magnetic permeability is applied to the molten areas to form the latent image. Process allows the prodn. of large numbers of copies from the same original without loss of quality.
