Patent DE-3003607-A1 (DE)
Inventor: KUHN FRANZ DR
IPC: G01J3/46
Filed: 1980-02-01
Abstract: PCT No. PCT/DE81/00027 Sec. 371 Date Sep. 9, 1981 Sec. 102(e) Date Sep. 9, 1981 PCT Filed Jan. 24, 1981 PCT Pub. No. WO81/02205 PCT Pub. Date Aug. 6, 1981.The invention relates to a method and to a circuit arrangement for the partial recorrection of color recognition spaces in color recognition. Before the color recognition, the color coordinates (color locations) of characteristic sample points are determined in the colors to be recognized and sample color numbers are allocated to them, said sample color numbers being deposited in a color recognition memory. All color numbers of the remaining color locations of the color space are determined from the sample color numbers and are likewise stored. The respective color locations or, respectively, memory locations occupied with the same color numbers form a color recognition space within the color space. For subsequent boundary correction of a color recognition space, at least one auxiliary color sample is taken from a color to be recognized in the area of the desired change and the necessary sample color number is allocated to it. The color numbers within a spatial cancel area around the color location of the auxiliary color sample are cancelled and, upon incorporation of all sample color locations and sample color numbers, new color numbers are instead calculated and stored for the cancel area.

Patent DE-3104116-A1 (DE)
Title: Trench cutting machine
Inventor: DUECKER GERHARD
IPC: E02F3/20
Filed: 1981-02-06
Abstract: The invention relates to a machine for excavating, reproducing and/or cleaning trenches and comprises a chassis (1), an adjustable side boom (2) supported on the chassis (1), and a working unit (7) which is linked to the end of the side boom (2) and has a tool housing (12) and a rotatably driven cutting tool (13) mounted in the tool housing (12) and exposed through a wall recess (42) of the tool housing for cutting work. As shown in particular by Fig. 1, the cutting tool (13) is here designed as a disc-shaped radial bucket wheel and is tightly encased by the tool housing (12) except for the area of the wall recess (42) provided in the peripheral wall and in the side walls. Furthermore, arranged in the top area of the tool housing is a screw conveyor (14) with a conveyor screw (16), orientated parallel to the rotational axis (15) of the radial bucket wheel (13), and a tubular conveyor-screw housing (17) which, in the area of a transition opening (18) common to both housings, is directly attached to the tool housing and projects axially beyond the latter on one side. This design of great simplicity results in a high cutting capacity with at the same time precise conveyance and delivery of the cut material. To vary the cross-sectional cutting contours, the working unit (7) can be pivoted about a vertical axis (30) intersecting the rotational axis of the radial bucket wheel and can be locked in different angular positions relative to the longitudinal axis of the trench so that different trench shapes can be formed or worked. <IMAGE>

Title: Appliance for pulling a single crystal from a crucible by means of a reelable traction member
Inventor: JERICHO KARL ING GRAD
IPC: C30B15/30
Filed: 1981-04-29
Abstract: The invention relates to an appliance for pulling a single crystal from a crucible by means of a reelable traction member to whose end, arranged above the crucible, a seed crystal holder is attached. The traction member, which is preferably a steel cable, is connected to a lift-drive device which is arranged on a platform rotatable about the traction member. The lift-drive device has a driven horizontal shaft with a take-up drum which can be displaced thereon longitudinally and onto which the traction member can be reeled tangentially. In order to achieve the object of being able to set, in an apparatus of this type, widely differing vertical speeds of the seed crystal holder, it is proposed according to the invention that the lift-drive device (66) has a high-speed drive motor and a low-speed drive motor (62), which act on the take-up drum (31) via shafts (53, 53a; 63) which can be separated from one another via a clutch (coupling) (64) but are coaxial. In this arrangement, the high-speed drive motor is linked to that shaft (53) which cannot be uncoupled, and the low-speed drive motor (62) is linked to that shaft (63) which can be uncoupled. <IMAGE>

Title: Parking brake operated by a pressure medium, in particular for rail vehicles
Inventor: CLEMMONS QUENTIN T
IPC: B61H15/00
Filed: 1981-06-05
Abstract: The invention relates to a parking brake, in particular for rail vehicles. This parking brake has a friction clutch which is assigned a nut (5) with a comparatively coarse thread which is secured against rotary movements on a threaded spindle (3) by the clutch by means of a force exerted by a multiplicity of disc or Belleville springs (21). The threaded spindle (3) is connected to a braking head. The force of the disc or Belleville springs (21) can be overcome by a pressure medium, for example compressed air, which is allowed to act on corresponding surfaces of a multiplicity of pistons (17) arranged in series so as to release the coarse-threaded nut (5) for rotary movement and thus takes up the axial movement during the normal braking operation or brake release operation of the spindle (3). <IMAGE>

Title: Reversal by light beam for high-speed printer ink ribbons
Inventor: SCHMIDT RONALD
IPC: B41J17/14
Filed: 1981-06-03
Abstract: The reversal by light beam makes it possible for the ink ribbons for high-speed printers to be manufactured more quickly and cost-effectively. This obviates the need for reversal rails or reversal foils to be mounted and likewise for the stamp with stamping ink. Instead, a perforation stamp is used. Two perforation stampings are required per ink ribbon, specifically where the reversal rails or reversal foils/ink ribbon transitions were previously located. On the high-speed printer, instead of the mechanical changeover switch a light barrier is mounted which switches over when the light beam shines through the holes of the perforation stamping. There are no longer any reversal rails or reversal films which could become detached or be mounted in misalignment and cause damage to the high-speed printer.
Patent DE-3126503-A1 (DE)
Title: Race finish camera
Inventor: FICHTER WALTER
IPC: H04N9/29
Filed: 1981-07-04
Abstract: In a method for manipulating film in a race finish camera, or in a race finish camera for carrying out the method, the aim is to reduce the consumption of the expensive film material. For this purpose, the race finish camera (1) is equipped with a removable storage chamber (11) for accommodating exposed film sections (17) from taking strips (15) and feed strips (16), and a shearing device (10) is arranged just behind the film exposing field (6) and in front of an inlet slit (13), which can be sealed in a light-tight fashion, of the storage chamber (11). The storage chamber (11) thus charged can be transferred away from the race finish camera (1) into a developing station (18). It is expedient to design the exchangeable film cassette (2) for the feed supply spool of the film (3) and the storage chamber (11) to be mutually exchangeable, and to equip them with feed channels (12), projecting far into the race finish camera (1), for guiding the film in the vicinity of the exposing field (6). <IMAGE>

Title: Eccentric shear for rolled stock moving at high speed
Inventor: ZWICK GERHARD
IPC: B23D25/12
Filed: 1981-07-13
Abstract: The aim of the invention is to increase the cutting rate of an eccentric shear with blade carriers mounted to revolve in eccentric drums which is used in light section and rod mill trains and is made to perform the cut starting from the stationary condition. The object of the invention is to simplify a shear of this kind in such a way that matching of the speeds of drive motors acting separately on the drum bodies and on the blade carriers, additional gear boxes and an electromagnetic reversing clutch (when operating with one drive motor) are eliminated, the weight of the shear is reduced, the increase in the cutting rate is achieved with an economically justifiable driving power and, by the balancing of all mass moments of inertia, a precisely defined run-up time for the maintenance of precisely the required cut lengths of rolled stock at high rolling speed is made possible. This is achieved by the fact that one or more drives running parallel are used to drive the eccentric drums via fixed gear stages and to drive the blade carriers via further fixed gear stages. <IMAGE>
Patent DE-3136416-A1 (DE)
Title: Roller-blind motor
Inventor: BAEUERLE WOLFGANG
IPC: E06B9/78
Filed: 1981-09-14
Abstract: The known roller-blind hand-operated drives are actuated by means of belts or gear mechanisms which, on the one hand, are sluggish and, on the other hand, require a special retaining and winding-up device. Both in terms of appearance and from a technical and handling point of view, this is not the best solution since even the retaining and winding-up device has to be mounted on site. The roller-blind motor is an improved roller-blind hand-operated drive, characterised in that, when paying out the roller shutter, a helical spring, which is installed in the hollow profile of the roller-blind roll, stores force which is used for opening or for winding up the roller shutter. The retaining device of the roller shutter is achieved by mounting the roller-blind roll with an automatic return-movement locking means. The roller-blind hand-operated drive is actuated by a non-endless cord which, in contrast to a belt pulley, has two chambers, that is to say one for winding up the cord and one for paying out the cord. The advantage lies in a larger actuating area, with the result that windowsills can be concealed, for example, by flowers or furniture.
