Title: Volume switching in radio alarm clocks
Inventor: RIEDER JOACHIM
IPC: G04G13/02
Filed: 1983-02-08
Abstract: Radio alarm clocks are generally known and to be found in almost every household. The so-called sleep circuit is a welcome feature in radio alarm clocks. However, up to now there has been only one volume control for the alarm circuit and the sleep circuit. Both functions require, however, different volumes for correct operation. This is achieved according to the invention by installing two volume controls. These are assigned to the respective function.

Patent DE-3332419-A1 (DE)
Title: Steering aid for power-driven vessels
Inventor: WITTKE MANFRED
IPC: F02B61/04
Filed: 1983-09-05
Abstract: In the area of the shaft installation in the submerged part of the hull, steering plates are pivotably arranged in front of the propeller. When the vessel is moving astern, the propulsion stream of the propeller is directed via these steering plates. This results in a lateral thrust, which considerably increases the manoeuvrability.
Patent DE-3335981-A1 (DE)
Title: Optical rear view system
Inventor: SCHROEDER WOLFGANG DIPL PHYS
IPC: B60R1/10
Filed: 1983-10-04
Abstract: The invention relates to an optical rear view system which corresponds to the principle of the Kepler telescope with an image reversal system and has an exit pupil for binocular vision which is situated comparatively very far behind the system and is comparatively large, a magnification of the angular field of vision being achieved on the object side. The beam path is deflected via a relatively small rear view mirror (e.g. external mirror on vehicles) onto a collecting lens; the component beam paths for the two eyes of the observer can be influenced behind the lens differently in the variation of direction in order to increase the horizontal extension of the field of vision, and the beam path is subsequently led via a prism or reversing mirror system and, possibly, a field lens, which can be omitted given favourable distribution of refractive power, onto a collecting optical operational group, which is relatively large in area, and directs the light of the imaging beam path directly onto the two eyes of the observer (Fig. 1). This takes place in such a way that the observer can view the image without any disturbing accommodation, that is to say in a relaxed fashion. <IMAGE>

Title: Combine-harvester monitor for indicating the cereal grain spread
Inventor: KAMENIK FRANC
IPC: A01D41/127
Filed: 1984-02-24
Abstract: The improved combine-harvester monitor for indicating the cereal grain spread provides for repeatable positioning of the display probes in the combine harvester with the aid of a universal mechanism, the output signal of each probe being conducted via a separate branch of the two-channel amplifier to a summation stage (15) which enables the operation both of each probe separately and also of both together to be monitored; each branch contains a calibration stage (12, 12') with a low-frequency filter and a high-frequency filter which allows the sensitivity to be set from the outside. The intensity of the probe signals is shown on a display instrument (17) which is located in the combine-harvester cabin. The probe signal which exceeds a predetermined value additionally triggers a visual and audible signal device in the combine-harvester cabin. <IMAGE>

Title: Encapsulated, compressed-gas-insulated switching installation having an earthing device
Inventor: PEITZ THEO ING GRAD
IPC: H02B13/075
Filed: 1984-03-13
Abstract: Earthing devices (1) in encapsulated switching installations are frequently also used for measurement purposes on the switching installation. This is not possible directly, however, since the stationary mating switching element (10) of the earthing device (1) normally carries earth potential and must therefore be arranged in an insulated manner for measurement purposes, and is to be connected to earth potential via detachable links. The invention is based on the object of improving the earthing device (1) such that it can also be used for measurement purposes on the switching installation, in a simple way. This is achieved according to the invention in that, for measurement purposes, the contact blade (9) can be connected in an intermediate position (measurement position) to a contact element which is arranged in an insulated manner. <IMAGE>

IPC: A24F19/00
Filed: 1984-04-26
Abstract: To avoid an excessively smoky atmosphere in private cars, the ash-tray (1) is connected to a suction device (2, 12). Butts and ash are retained in a catchment chamber (9, 10), while the suction air flow, freed of all solids, escapes into the open atmosphere. Smouldering parts are extinguished in a water tray (6). Inserted into the suction line is a deflector (7), which deflects butts and other solids upstream or in front of the suction pump (3) into a special compartment (9) of the catchment chamber in order to avoid interfering with the operation (Fig. 3). <IMAGE>

Abstract: The intention is to provide from a small number of individual components a gearing arrangement of low overall height for motor-vehicle auxiliary drives with a motor, which gearing arrangement is to be simple to manufacture and assemble and reliable in operation even under high thermal loads. In the gearing arrangement, an output shaft (5) supported in a gear case (2) is connected with an elastic rotary take-along connection to a worm input shaft (7) projecting into the gear case (2); according to the invention, only a single one-piece plastic gearwheel (3) with spokes (34 to 37) arranged between a radially outer gearwheel rim (31) and a radially inner gearwheel hub (32) is provided for this purpose between the input shaft (7) and the output shaft (5), the said spokes having a stiffness in the axial direction which produces a dimensionally stable rotary drive and a stiffness in the tangential direction which produces elastic flexibility in the rotary drive in the event of an abrupt start. The output shaft (5) is moulded directly to the gearwheel hub (33) or into a gearwheel bearing sleeve (32) arranged concentrically and at a radial distance from the latter. One application, in particular, for which the invention is suitable is that of motor-vehicle window lifter drives with a motor. <IMAGE>

Title: Method and device for forming a rod of tobacco, and cigarette which is manufactured by means of such a rod
Inventor: HEITMANN UWE
IPC: A24C5/18
Filed: 1984-09-29
Abstract: The invention relates to a method and a device for forming an endless cigarette rod, from which cigarettes are continally severed. To this end, a thin layer of tobacco is applied to a rod conveyor, the said layer having a low height in relation to the width perpendicularly to the conveying direction; as it is conveyed further, this thin layer of tobacco is converted into a rod, the inner region (core region) of which has a lower density of tobacco than the outside region. The tobacco rod is preferably formed by first making a U-shape of tobacco which is kept as free as possible at the centre and then deforming the U-shape to form a closed rod. The invention also includes a cigarette which is manufactured using the method and the device according to the invention. <IMAGE>
