Patent DE-3110897-A1 (DE)
Title: Letter opener with tear string
Inventor: MILOVANOVIC ILIJA
IPC: B65D27/38
Filed: 1981-03-20
Abstract: The technical composition is composed of an envelope which can be opened, on tearing a small hole by hand at the corner, by a tear string on the fold line. A hole for tearing does not absolutely have to be necessary but the best solution is to punch tiny holes (as in the case of stamp edges) obliquely at the corner of the envelope. The technical problem was chiefly to open the letter without any aids. With my invention, any one could open the letter with one tear without difficulty and without any aids. Only one problem arises in the production of the letter, that is that the tear string cannot be stuck on before the envelope has been punched through. In my opinion, the tear string can be stuck horizontally onto the envelope roll beforehand (cf. Fig. 5), and when punching out the envelope, and also, at the same time, punching out the tiny holes, the tear string is already at the fold line. By this means, further operations are eliminated. <IMAGE>

Patent DE-3125544-A1 (DE)
Title: Stable optical resonator for lasers
Inventor: ALTMANN KONRAD DIPL PHYS DR
IPC: H01S3/08
Filed: 1981-06-29
Abstract: Building on a novel theory of the optical resonator, it is possible in a simple manner to produce pulsed laser radiation. This theory indicates that a spontaneous coupling of the transversal modes occurs in multi-mode operation in stable optical resonators, which results in a laterally oscillating laser beam. Pulsed laser radiation emerges since the exit mirror is translucent or partially translucent only at specific points in the region over which this laser beam passes. <IMAGE>

Patent DE-3126885-A1 (DE)
Title: Drive arrangement for vehicles, especially passenger vehicles
Inventor: HAGEMANN GOTTFRIED ING GRAD
IPC: B60W30/18
Filed: 1981-07-08
Abstract: The invention relates to a drive arrangement for vehicles, especially passenger vehicles, with a drive motor formed by an internal combustion engine and an automatic transmission having a hydraulic clutch or hydrodynamic torque converter. It is proposed that the drive arrangement be further equipped with a device for automatic cut-off of the engine in certain operating conditions of the vehicle by automatic disengaging of a clutch assigned to the transmission and interruption of the supply of one engine operating variable and for automatic restarting of the engine on ending of the conditions as a function of the position of the accelerator pedal, the engine being started by re-engaging of the clutch above a minimum speed of travel of the vehicle and below this by operation of a starter motor assigned to the engine. In order to achieve reliable starting of the engine by the vehicle mass even when the thrust moment available below a limit speed of approximately 25 to 40% of the maximum speed of travel for the respective gear, assigned to each gear selected, can no longer be sufficiently transmitted to the engine crankshaft by the converter or the clutch, it is proposed according to the invention that in such cases the automatic transmission be induced to automatically shift back into the next lowest gear. In so doing, it is intended that this changing down be maintained only until the engine has started and has a minimum speed of, for example, 500 rpm. The changing down can be achieved by an adjustment of the control device assigned to the transmission manual selector lever or by generating a signal resulting in changing down, which corresponds to the kick-down signal. <IMAGE>

Title: Characteristic transmitter
Inventor: HANTKE KLAUS ING GRAD
IPC: H03H11/04
Filed: 1982-02-23
Abstract: The invention relates to a characteristic transmitter for presetting an output voltage (Ua) as a function of an input voltage (Ue), the characteristic which describes the relationship between the input voltage (Ue) and the output voltage (Ua) being composed of a plurality of straight sections (G0-G3). A separate summing amplifier (1, 2), which is connected with feedback diodes in an ideal-diode circuit, is provided for each straight section (G1, G2) with an output voltage (Ua) depending on the input voltage (Ue). The input voltage (Ue) is supplied to a first input (E1) of each summing amplifier (1, 2). That input voltage value (Ue1, Ue2) from which the associated straight section (G1) is intended to become effective is on a second input (E2) of each summing amplifier. In the case of the characteristic transmitter according to the invention, all the straight sections are defined only by summing amplifiers so that the characteristic can be set very precisely. In addition, parallel displacement of the characteristic is possible by varying only one parameter. <IMAGE>
Patent DE-3208553-A1 (DE)
Title: Gas protection device
Inventor: PREUKSCHAT FRITZ
IPC: G08B17/117
Filed: 1982-03-10
Abstract: Gas protection device. Said gas protection device is intended to prevent accidents as a result of gas emerging from leaking pipelines. In contrast to known gas protection devices, this device is designed such that it is effective even when nobody is in the house. This object is achieved in that a cable leads from the laid, known early-warning system to the main gas tap and an actuating motor is assigned to this main tap, which actuating motor is supplied with power from a battery via the cable, by means of a contact in the early-warning system, and thus closes the main gas tap. At the same time, the main electrical power line is rendered inoperable in order to prevent a spark occurring if a switch is operated. An early-warning system must, of course, be installed in every room where there is a gas connection, together with a cable connection to the actuating motor and to the main protection device.
Patent DE-3211249-A1 (DE)
Title: Method and device for combustion of straw, chopping chips, planning chips, sawdust and similar fuels
Inventor: TRUNKENPOLZ FRIEDRICH ING
IPC: F23G5/14
Filed: 1982-03-26
Abstract: Fuels, such as straw or chopping chips, are supplied continuously to a combustion chamber and burned under the action of primary air. By supplying secondary air, postcombustion then takes place, the waste gases being supplied to a heat exchanger after removal of ash particles. Good combustion with a high degree of efficiency for energy recovery is achieved, if the fuel is introduced into a combustion chamber arranged in a lying manner, into which the primary air is blown in the starting region and the secondary air is blown in the end region. During the combustion process, the fuel is moved further along the combustion chamber and at the same time broken up. A device for implementing this method has a horizontal combustion pipe (2) which at one end is connected to a worm conveyor (4) and at the other end is directed towards an ash filter (6). The combustion pipe (2) has a conveying device (24) with the same conveying direction as the worm conveyor (4). Passage openings (16) for the primary air are provided in the end wall of the combustion pipe (2) on the worm-conveyor side and passage openings (20) for the secondary air are provided in the end region of the pipe casing (19) facing the filter. <IMAGE>

Title: Lubricating device for a seal
Inventor: SHEPPARD WILLIAM LEWIS
IPC: F16N15/00
Filed: 1982-03-26
Abstract: A description is given of a lubricating device for a seal of a mechanical device. The mechanical device has a first component, a second component, which is movable relative to the first component, and a flexible seal which operates between the components. A magnet is provided which is fixed on the first component and is arranged in such a way relative to the second component that there is a gap between them, adjoining the flexible seal. The magnet is polarised in such a way that one pole is situated next to the seal and the opposite pole is remote from the seal. The magnetic fields of the magnet are partially short-circuited to ensure that the primary magnetic field between the poles is situated in the vicinity of the gap. A supply of lubricant is provided in the gap. The lubricant contains magnetic material which is exposed to the forces of the primary magnetic field, as a result of which the lubricant can be caused to enter the gap and/or remain in the gap next to the flexible seal. <IMAGE>

Title: Intermittent press for the drainage of liquid-absorbing materials, especially wet laundry, with a press floor carrying the material to be drained and with a preferably vertically movable filling basket which receives the material to be drained and which can be placed onto the press floor
IPC: D06F47/00
Filed: 1982-05-28
Abstract: Intermittent press for the drainage of liquid-absorbing materials, especially wet laundry, with a press floor carrying the material to be drained and with a preferably vertically movable filling basket which receives the material to be drained and which can be placed onto the press floor. Intermittent presses for the drainage of wet laundry are equipped with a vertically movable filling basket which, before feeding, is lowered onto a press floor. After feeding with wet laundry, a diaphragm is introduced into the filling basket and can be subjected to a pressure medium. Formed from the wet laundry is a so-called press cake which has to be transported to a following dryer by means of a suitable conveyor. The intermittent press according to the invention is characterised by the twofold function of the press floor. After the filling basket has been lifted off, thereby releasing the press cake formed, the press floor is first displaced in the plane of the supporting surface and thereafter tilted about a horizontal axis, with the result that the press cake automatically comes loose from the supporting surface of low coefficient of friction and slides in the desired direction. This effect is also additionally increased if, instead of the use of an air-permeable material, the press floor is designed so that the coating or covering consists of an air-permeable material and the press floor is equipped with a compressed-air connection for applying pressure to the space located between the press floor and the coating or covering, since then the air flowing through the covering acts on the underside of the press cake, as a result of which a lifting-off effect reducing the frictional forces to be overcome occurs. Depending on the constructive design, such an intermittent press can be followed directly by at least three dryers. <IMAGE>
