Title: Electronic range indicator for motor vehicle - has switch array powered by vehicle ignition voltage used to indicate selected transmission range
Inventor: LIPPMANN RAYMOND
IPC: F16H63/42
Filed: 1990-01-23
Abstract: The electronic range indicator apparatus has a switch array powered by the vehicle ignition voltage used to indicate the selected transmission range during both on off periods of the vehicle. During on periods of the vehicle, the ignition voltage is transmitted through the closed contacts (if any) of the switch array, and an electronic control module decodes the output of the switch array and lights the indicator indicia corresponding to the selected ranqe. During off periods of the vehicle, the ignition feed to the switch array is open circuited. In such case, the control module intermittently reverses the potential across the switch array, and lights the appropriate indicator indicia using a reverse logic decode scheme.

Title: Sewing machine optical sensor - has drilling in fabric sliding surface as light passage sealed by transparent plug of adhesive hardened by UV radiation
Inventor: ANTES LUDWIG
IPC: G02B7/02
Filed: 1990-05-21
Abstract: The optical passage for the light for a sensor at a sewing machine, in a sliding surface such as the needle plate of the presser foot sole to monitor the fabric edge and the like, is filled by a plug (6) of an adhesive material hardened by UV light. - The pref. adhesive material is a urethane methacrylate. The drilling is covered at the end away from the fabric's sliding surface (1a) by an underlay (8,9) coated with Teflon (RTM). The adhesive material is inserted into the open end of the drilling, as a drop, in a volume and a viscosity and surface tension so that the outer surface automatically forms a convex lens outer surface extending from the sliding surface (1a). Alternatively, the end of the drilling at the sliding surface (1a) can be covered by a Teflon (RTM) coated underlay, and the fluid adhesive drop is inserted from below. The liq. drop of adhesive is hardened by UV radiation for 30 secs. and then given a final hardening for about 30 mins. at about 120 deg.C. The underlay (8,9) is removed after the UV radiation has been applied, and before being treated with heat. The fluid drop forms a plug at the drilling for the passage of light in a light sensor at a sewing machine, where the outer surface of the drop acts as a lens.

Abstract: A transport vehicle (10) with a chassis (14) having an interchanging device, an interchangeable body (19) which can be positioned on the chassis (14) and removed and has at least one unit (22) which is to be driven, a coupling line (26) in particular for connecting a driving drive device (28), which is present on the vehicle side, to a power output device (24) which is to be driven and is present on the interchangeable body side, and a coupling device (40) which is present inside the coupling line (26) and has coupling elements (42, 44) in particular for coupling the vehicle-side drive device (28) to the interchangeable body-side power output device (24) is characterised by the fact that a vehicle-side coupling element (44) and an interchangeable body-side coupling element (42) are present and the drive device (28) is automatically coupled/decoupled to/from the power output device (24) when the interchangeable body (19) is positioned/removed. By means of the automatic interlocking of the coupling elements when the interchangeable body is positioned the coupling process which is still to be carried out manually in known vehicles is superfluous. The automatic coupling process increases user friendliness when changing interchangeable bodies of this kind enormously. At the same time, there is no longer any risk of injury to the operator. <IMAGE>

Title: Rake for fine strainer grille of sewage-cleaning appts. - has arm swinging through right-angle only
Inventor: HARTMANNSHENN HERBERT
IPC: B01D29/07
Filed: 1991-06-14
Abstract: The rake has an arm (3) which moves only 90 deg. Pref. on the return run, the arm (3) moves with a gap of x from the outward movement (R1 and R2) over the rake grille to the channel floor. The rake has an arm fixed to the output shaft of a geared motor, and which is swung down along a first arc. At the same time a second motor acting via a rack and pinion on the mounting plate of the first lifts it along a second arc. This gives a rearwards movement of the arm, which thus swings clear of the grille to the trough bottom. At bottom dead-centre the first motor switches off and the second reverses, bringing the arm to the trough bottom. The first motor restarts in the opposite direction, clearing the grille. USE - For communal and industrial water purification installations.

The system aligns the data disc axially with a fixed disc that contains the heads in microform. In principle, the heads are arranged on a radial line (1.2). However, due to the high density of the tracks, single heads are assigned a single radial line. The total number of lines is the same as the number of tracks. ADVANTAGE - Greatly improved access time.
Patent DE-4131328-A1 (DE)
Inventor: DIRKS ROLF
IPC: H01H9/20
Filed: 1991-09-20
Abstract: 2.1 In the case of gas-insulated switching installations, specific drive openings and the cable connecting space must be closed during a switching process, for safety reasons. However, such locks have the disadvantage that they can easily be circumvented as soon as the cable connecting space is open. 2.2 The invention indicates a way in which it is possible to close this large security gap. For this purpose, an additional connecting element is inserted between a closeable opening (1) and the operating shaft (4) in such a manner that the operating shaft (2) is locked as soon as the closure device (3a or 3b respectively) is opened, and is released when the closure device (3a or 3b respectively) is closed. 2.3 Such locking systems are used in medium-voltage switching installations, preferably in metal-encapsulated, compressed-gas-insulated switching installations. <IMAGE>
