Title: Device for the automatic cleaning, disinfection and deodorisation of toilet pans
Inventor: FILUSCH WOLFGANG
IPC: E03D9/03
Filed: 1982-09-04
Abstract: The present invention is suspended in the same way as known devices below the inner edge of the toilet pan, so that the active composition present in the housing of the device is dissolved by the water and carried into the toilet pan. In order to prevent uncontrolled dissolution of large amounts of the active composition and passage into the toilet drainage as early as during the flushing operation, the invention provides a plastic container in which the entering amount of flushing water dissolving the active substance is limited and the flushing water laden with active substance is essentially not passed into the toilet pan until the end of the flushing operation. As a result of suitable dimensioning and design of the inlets and outlets, the flushing water inter alia, which has flowed in is retained. Fig. 1 of the drawing shows the plastic container with the water chamber arranged in the centre, lateral active compositions and the water inlet orifice as well as the water outlet orifice. <IMAGE>

Patent DE-3238611-A1 (DE)
Title: Rowing system for model rowing boats with two rows of oars
Inventor: WEDEMEYER ERWIN
IPC: A63H23/04
Filed: 1982-10-19
Abstract: The technical problem is driving two rows of oars and using them optionally in the forward and rear direction. This invention relates to a drive divider which is driven by an electric motor and whose coupling element can be coupled by a remote control servo either to the drives of the two rows of oars at the same time or optionally separately coupled to the row on the starboard side or port side (alternate coupling). While the horizontal rowing movement is brought about by the body inclination of the oarsmen, the submersion and lifting out of the oars takes place by means of lever extension arms which are moved up and down at the corresponding angle by cam discs on both sides of the drive divider and via linkages in the limit positions of the horizontal movement. Since the rotational direction of the drive divider and thus also of the cam discs can be reversed by changing over the motor, the submersion of the oars with respect to the body inclination is reversed. Therefore, if the oars are submerged as soon as the body is inclined backward, the oar movement in the water begins in the opposite direction and moves the boat backwards. This mode of operation also applies for the optional use of rows of oars.

Title: Carrier bag of plastic film with carrying strap and process for the manufacture thereof
Inventor: BRIDE HELENE CHRISTIANE
IPC: B31B19/86
Filed: 1982-11-11
Abstract: Carrier bag of thermoplastic film and process for the manufacture thereof. The carrier bag has welded side edges and at least one carrying strap of weldable plastics, the ends of which are welded to the carrier bag in the region of the upper end of the side edge welds. The carrying strap (16) is designed as a shoulder strap with a length that is greater than the bag width. The carrying strap is only mounted at its ends with respect to the carrier bag (20) and can be freely pulled out of the carrier bag virtually to its full length. For manufacture of the carrier bag a web of material which is folded around its longitudinal central axis is separated into carrier bags by cutting welds effected perpendicularly to the longitudinal axis. The carrying strap taken off from a supply roll is inserted between the halves of the material web by a carrier, which is adjustable in the cycle of the advance movement of the web of material vertically to the longitudinal extension thereof, and then welded to the web of material during the cutting and welding processes and cut off (Fig. 1). <IMAGE>
Patent DE-3244546-A1 (DE)
Title: Belt holder
Inventor: JUERGENS WALTER DR ING
IPC: B60R22/32
Filed: 1982-12-02
Abstract: In motor vehicles, belts are used as a device for retaining persons in the event of accidents. They have the disadvantage that, after the accident, it is very difficult and sometimes impossible to open them. The invention proposes to equip this belt with a holder which has a timer. After a particular time after the accident, this holder opens automatically. In the present case, this takes place by means of a flowable substance which, after the collision, can flow out of its position to another location as a result of the pulling force. The flow speed and therefore the opening time of the belt can be determined by means of the outflow orifice and the force acting on the flowable substance.

Patent DE-3300761-A1 (DE)
Title: Rotary internal combustion engine
Inventor: SCHMIDT WALTER
IPC: F01C11/00
Filed: 1983-01-12
Abstract: The rotary internal combustion engine comprises a light alloy engine power section, which spatially divides the functions of the compression and combustion process and permits the transmission of kinetic energy to certain pressure blades in the pressure blade housing by way of three exhaust ports. The cooling air generated by a pressure fan is led by way of cooling ducts through the pressure blade housing to the exhaust, so that the old gases are removed and the pressure blades cooled and a part of the cooling air is fed to the mixing chamber for the after-burning process. Due to the assignment to a low-wear piston orbit with a cylindrical inner seal, sealing off from the sealing rings of the cheek plates is simultaneously achieved. By means of stop bolts on the rotating piston a limit stop to the ball bearing races supported in housing partition wall and housing end covers is achieved, which races are supported all-round at a constant distance from the piston orbit front face. The rotating pistons are provided with angled, spring-loaded seals. For lubrication of the rotating pistons oil ducts are provided, which in a certain piston position establish a connection to an oil duct provided in the piston guide cylinder, which duct is fed by hydraulic fluid at the piston adjustment pressure.

Inventor: WESTPHAL KLAUS
IPC: G02B7/24
Filed: 1983-02-18
Abstract: A microscope tube having several sections articulated with respect to each other. A first stationary section (1) is hinged to a second section (2) which can swing upwardly and downwardly, and this is hinged to a third section (3) which hangs downwardly from the second section, the free lower end of the third section being swingable horizontally toward and away from the observer or user of the microscope. The third section has a fourth section (4) hinged to it to tilt on a horizontal axis, and this fourth section carries the eyepiece of the microscope. With this arrangement, the eyepiece may be adjusted to various positions vertically and horizontally to suit the comfort of the observer, and may be tilted to various viewing angles quite independently of its vertical or horizontal position. Mirrors within the tube at the hinge joints direct the optical beam properly from one section into the next section, and these mirrors turn through half the angle of swing when one section swings relative to the next. An additional optical system within the tube forms an intermediate image, and the observer sees the object in proper erect position in proper side-to-side relationship, rather than reversed. Provision is made for attachment of a camera or other desired auxiliary apparatus.
