Title: Method and arrangement for representing a search for a search word on a screen
Inventor: HAPEREN PETER VAN
IPC: G06F17/30
Filed: 1982-10-27
Abstract: A search for a particular search word within a text on a screen (BS) of a text station is represented in such a manner that, after the text has been called up and a search word key (SW) activated, the text is partially shifted downwards by one line on the screen in order to release a writing line for the representation of the search word. The search word is entered by means of the keyboard (TA) and represented in the writing line. After the search word key (SW) has been operated again, the text is represented again in the original manner and the search begins. The search always occurs in the text represented in the writing line. When a word corresponding to the search word is present there, this word is marked. If the word is not contained there, the text is shifted upwards line by line until a corresponding word has been found. <IMAGE>

Title: Friction clutch with sprung diaphragm-spring clamping
Inventor: FAEDLER KURT
IPC: F16D13/58
Filed: 1982-11-09
Abstract: The invention relates to a diaphragm-spring clutch of compact construction in which the swivel-mounting of the diaphragm spring on the clutch housing is held in such a way by axially acting spring clamping that no lift-off losses can occur in the engaged and disengaged condition - even in the case of wear - in this mounting. For this purpose, a spring tab is bent out of the material of the diaphragm spring and is under prestress. On the side opposite the spring tab, a hardened steel ring is preferably provided as abutment element. The angled spring tabs are arranged in the radially outer end regions of the separating slots of the spring tongues. By virtue of this design of the diaphragm spring, it is possible to dispense with a separate spring element.

Title: Photographic camera having a film transport device driven by electric motor
Inventor: SITZLER KLAUS
IPC: G03B17/42
Filed: 1982-11-11
Abstract: A motor (3) arranged in a power-transmission chain (4, 5 and 6) is mounted on a pivotable holder (2) which actuates a motor switch (9, 9b) via a projection (2a) and is spring-loaded in an initial position. When the transmission (5 and 6) is stopped, either by the engagement of a latch (18) or at the film end due to the film itself, the motor (3) initially drives its driving pinion (4). The latter rolls on the circumference of the toothed wheel (5a) which is in contact with it and has been stopped, and pivots the holder (2) in the process. As a result, the motor switch (9) is opened, the motor (3) is switched off and a contact arm (9a) is latched in the open switch position on a latching lever (10, 10a). When the tripping device is actuated, a control member (16) of a tripping device (14) neutralises the latch, so that the motor switch (9) closes once again. An insulating piece (16c) arranged on the control member (16) interacts with the motor switch (9) in such a way that when the tripping device is actuated while the motor is being driven malfunctioning of the device is ruled out. <IMAGE>

Title: Novel process for gas purification - activation sorption
Inventor: SCHULTESS WOLF DR ING
IPC: B01D53/50
Filed: 1983-03-26
Abstract: The novel process for noxious gas separation, the so-called activation sorption, is based on the exploitation of mechanical activation of solids for dry separation of noxious gas from exhaust gases. The essence of the invention lies in the exploitation of the active states of solids produced by intensive mechanical stress, which active states are distinguished by the presence of deformations, faults and destruction of the crystal lattice. As a result of these changes in the state of order in the crystal lattice, the activated solids are unstable and have increased reactivity. They are thus in the position to chemically and physically bind noxious gases, some of which considerably pollute the environment such as, for example, SO2, SO3, H2S, F<->, Cl<-> and hydrocarbons, more rapidly and more productively (in the stoichiometric sense) than non-activated, conventionally used additives. The performance and economic efficiency of the novel process are, moreover, based on a further effect of the mechanical activation: stable agglomerates - likewise caused by the active state of the solids - are formed, the separation of which after binding the noxious gas is possible by simple mechanical dust removers. Binding the noxious gas is carried out most effectively directly in the activation reactor (vibratory mills or similarly functioning units). For large quantities of exhaust gas having noxious gas fractions, parallel connection of activation and ... Original abstract incomplete. <IMAGE>

Title: Plant for waste-water purification
Inventor: MENGES MARTIN DIPL ING
IPC: B01D21/00
Filed: 1984-04-11
Abstract: The plants conventional hitherto have a relatively high space requirement for the individual settling tanks and screen grid. A possibility is created by the invention to carry out the mechanical prepurification stage in the smallest possible space. In relatively small plants having greatly varying loads and times with zero feed, this purification stage is simultaneously utilised as a buffer for maintaining the biology and designated as nutrient tank. A closed nutrient tank (5) is proposed, to which the untreated water is fed in the upper part. The screen grid (8) is arranged above the inlet opening (7) for the untreated water, and a rotatable carrier (13) as a fat separator is located at the height of the liquid surface (11). The discharge end of the screen grid (8) and the fat discharge opening (14) open into the drop shaft (9) which is connected to a receiver (10). The available height of the plant is utilised for the transport of the fat and the screen material, as a result of which complex transport units are dispensed with. <IMAGE>

Title: Diaphragm for reducing noise in automatic safety-belt reeling mechanisms
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/40
Filed: 1984-08-30
Abstract: The invention relates to a diaphragm for reducing the rattling noises caused by sensing and control parts in safety-belt reeling mechanisms. A diaphragm 1 loaded by its own weight or by spring force covers the blocking teeth 3 of a blocking disc 2 to such an extent that only an engagement depth 8 still remains free. The possible total ratchet stroke 10 is thereby reduced to a smaller free ratchet stroke 11. Lower rattling noises occur as a result of the damping material of the diaphragm 1 and the reduced ratchet stroke. In the event of activation, depending on the particular version, the diaphragm 1 is raised, pivoted or bent by the blocking ratchet 4 which is pushed into the toothing 3 of the blocking disc 2. <IMAGE>
