Patent DE-3836310-A1 (DE)
Inventor: HAUCK DIETER
IPC: B41F33/08
Filed: 1988-10-25
Abstract: In a process for the control of switching operations on a printing press in which an angle sensor is provided on a shaft, the respective angular position is compared with stored angular positions; in case of agreement, a switching operation assigned to the respective angular position is triggered. In particular, a rotary disc 12 on the main press drive has marks which can be sensed opto-electronically to provide pulses representing angular-speed signals A, B from which the actual angular position of the press can be evaluated. Memory 39 stores data concerning the angular positions of the press which trigger control signals for various operating switches 6-11; interfaces 47, 48 from format-measuring devices and from a keyboard determine which data is relevant, eg for recto-and-verso using a turning drum; this data is fed via register 36 to comparator 35 so that specific angular positions reached by the press cause the desired control signals to be triggered at the correct moment. <IMAGE>

Title: Lighting device for reducing the dazzling of the driver of a vehicle by the light of the oncoming traffic
Inventor: ONDREJCSIK COLOMAN
IPC: B60Q1/14
Filed: 1989-03-17
Abstract: Lighting device for reducing the dazzling of the driver of a vehicle by the light of the oncoming traffic. In order to attenuate the oncoming light in road traffic, rail traffic and water traffic at night without the vehicle's own light being adversely affected, the field of vision of the driver of the vehicle is partially covered with a light screen of quickly changing translucency, the said light screen holding back the majority of the oncoming light which is emitted without interruption. The headlamps are either equipped with similar screens or with pulse lamps which function synchronously with the field of vision screen so that the vehicle's own light is usually emitted during the opening periods of the field of vision screen and is consequently perceived with a minimum degree of loss. In the case of pulsating oncoming light, the attenuation is achieved in that all the lighting devices according to the invention function with the same control frequency; since the blocking periods are longer than the opening periods, the lighting devices of the oncoming vehicles are in antiphase in most cases.

Abstract: A baker's oven with heating gas circulation has a number of baking chambers (1) above one another and, in between or above these and below these, radiators (3) which are flowed through by the heating gases and connected to distribution and collection shafts (11, 12) situated on the rear side of the baker's oven. Each radiator (3) is divided, by an intermediate wall (8) which does not quite reach as far as the front wall (6), into forward and backward running flues (9, 10) for the heating gases, which merge with one another at the front wall (6), there being provided in the places of increased heat requirement means for bringing about an intensified heat transmission. In order, with as low a pressure loss as possible in the circulating circuit and with simple construction, to provide effective measures for intensifying the heat emission in regions of increased heat requirement, the forward and backward running flues (9, 10) are formed by a horizontal intermediate wall (8) and arranged above one another. Alternatively or additionally, it is envisaged that on the one hand the height of the forward running flue (9) of the radiator (3) decreases in the direction of flow of the heating gases and that on the other hand, within boundary layers, close to the wall, of the heating gases flowing through the flues (9, 10), in the front part of the radiator (3) and at a distance from its inner wall surfaces, transverse rods (13) are arranged. <IMAGE>

Title: Conversion of cement clinker prodn. from wet to dry process - involves sepg. original clinker oven into a shorter oven and cooler, drier and cyclone heater with calcified are linked to the oven
Inventor: WOLTER ALBRECHT DR
IPC: F27B7/20
Filed: 1989-09-06
Abstract: Converting the prodn. of cement clinker from a wet process to a dry process is claimed. A suitable prodn. line is also described. The long rotating klinker oven used in the wet process is divided into two sections. One section becomes a shorter clinker oven and the other becomes a clinker pipe cooler to which a further cooler is attached. A drier is connected to the short rotating oven for drying the mechanically dewatered sludge. A cyclone pre-heater with a calcifier is also connected to the short oven. The original long oven from the wet process is sepd. into a short rotating oven (10) and a klinker pipe cooler (11). Cement clinker from the oven (10) is cooled from 1300-1000 deg.C. in the clinker pipe cooler (11). A cooler (12) from the original wet process is attached to the clinker pipe cooler (11) and cools the cement clinker further from 1000-500 deg.C.. The original cooler (12) with air blowers (13,14) has insufficient capacity for the increased throughput and therefore a further post-cooling stage (16) reduces the temp. to less than 100 deg.C.. USE/ADVANTAGE - Converts a current wet cement klinker process into a dry process with low investment costs. Energy requirements are less and klinker prodn. is increased.
Patent DE-3931455-A1 (DE)
Inventor: SCHNEIDER ERICH DIPL ING
