Title: Spectrometer for use in space satellite - has optical system with field aperture disperser and radiation receiver
Inventor: AVANESOV GENRIKH ARONOVICH
IPC: G01J3/28
Filed: 1982-01-11
Abstract: The spectrometer for the remote examination of the earth's surface has high spectral and spatial resolution and is suitable for satellite use and has a field aperture (2) arranged behind the optical input system (1). This provides a spatial resolution of the image of a section of the earth's surface, which passes to a dispersive device in the form of a transparent holographic diffraction screen (3) and a two-dimensional solid-state image receiver (4). The latter converts the received radiation flow into an electrical signal, which is processed by a registering and processing system (5). Between the diffraction screen (3) and the image receiver (4), a fibre-optic element (10) is pref. arranged, so that an image of the spectrum is generated on its front surface (11) the dimensions of this image being adapted to those of the photo-sensitive surface of the image receiver. The processing system pref. has an operating store connected through an analogue/ digital converter to the output of the image receiver, with separate means of forming blocks of spectral and spatial information on the output-side of the operating store.

Title: Step motor for large quartz-controlled clocks - has U=shaped stator sheet with one branch having stator coil and pole pieces of differing length
Inventor: KRAMER GERD
IPC: G04C13/11
Filed: 1982-12-15
Abstract: The motor has a stator sheet in the form of 'U' whose branches are longer than the transversal piece of yoke. The stator coil is driven onto one branch (14) of the stator sheet which is longer than the other branch. Also in that branch, next to the coil, is a semi-circular hollow which constitutes a pole piece. The hollow portion opens in the direction of the stator axis which passes parallel to the branches in a straight line. The centre of the arc of the circle formed by the hollow portion is offset w.r.t. the stator axis in the direction of the longer branch. The axis of rotation (1) of a rotor lies along a line parallel to the stator axis and passes through the centre of the circle but is offset w.r.t. this centre. The length of the intermediate space between the stator branches and transverse to its axis is not at any point less than the thickness of the neighbouring coil. The shorter stator branch ends at approximately the same point as the external extremity of the polar piece.

Title: Device for windscreen wipers having sweeping with a time delay at the two extreme positions of the sweeping angle.
Inventor: MULLER GUY
IPC: B60S1/08
Filed: 1982-12-23
Abstract: According to the invention, a brief and automatic time delay of the sweep at each of its extreme sweep positions is ensured by the discharge of a capacitor C3 in series with a resistor of constant value R19 when a movable contact 6, moved at the same time as the sweep, arrives at two intermediate positions A, C, each of which is in the vicinity of an extreme position. To this automatic and brief time delay, the operator can add an adjustable time delay by manoeuvring an adjusting potentiometer R10 in series with the resistor R19 which determines the automatic time delay. The arrival of the sweep at the intermediate positions also controls the short circuit of the motor 1. This can be used for equipment of motor vehicles.

Title: Process for the manufacture of pure fragrances (flavours) from essential oils and fragrances (flavours) obtained
IPC: A23L27/12
Filed: 1983-03-25
Abstract: The process for the manufacture of pure, water-soluble and 100 % natural fragrances (flavours), from essential oils, especially of the hesperidia, comprises the following stages: A. The fresh essential oil is distilled under reduced pressure in order to separate most of the terpenes; B. The residues of distillation A are distilled in their turn, and the remaining terpenes are separated under a lower pressure, and then the aromatic substances under final vacuum; C. The terpenes which come from distillations A and B are extracted with aqueous ethanol in order to separate the volatile fragrances (flavours) into alcoholic solution; D. The alcoholic extracts obtained during Stage C are subjected to an extractive azeotropic distillation to remove the terpenes with the minimum of alcohol; E. According to a preferred process, the terpene-free alcoholic solution obtained during Stage D is diluted with water and the fragrances (flavours) present are extracted with a volatile solvent; the solvent phase is concentrated, after which the final traces of solvent are removed; F. The soluble, pure fragrance (flavour) is obtained by combining the aromatic fraction obtained according to Stage E and the fraction distilled under final vacuum, obtained according to Stage B. Use in the food trade and in perfumery.
