Title: Vacuum cleaner for floors and carpets - is fitted with water spray and has water reservoir between walls of jacketed housing
Inventor: STETTNER GERHARD ING GRAD
IPC: A47L11/30
Filed: 1980-06-07
Abstract: The vacuum cleaner fitted with a water spray (15) has a double-wall housing (1). The inner housing (2) is fitted with a container (3) to collect the dust and dirty water delivered by the suction pipe (6). A fan (11) sucks air out of the inner housing through the filter (20) and a float valve (19). The dust and dirty water remain inside the collector. When the collector is filled with water to the maximum level, the ball of the float valve shuts off a duct (21) leading to the fan. The clean water reservoir (13) is formed by the space between the inner and outer walls of the housing. This design of double wall increases the rigidity of the housing and also acts as a sound barrier to reduce the noise from the cleaner.
Patent DE-3021647-A1 (DE)
Title: Utilising unused TV picture frame lines - using supplementary audio transmission and code-responsive interrupt switch
Inventor: STREHL HERBERT DIPL ING
IPC: H04N7/088
Filed: 1980-06-09
Abstract: Unused picture frame lines are exploited for the compressed digital transmission of supplementary audio information in teletext services. The system comprises a frame data store (UT) and a store (bt) for the associated audio information. The former supplies a re-coding circuit and buffer (VTCO) to be able to transmit a picture frame in a single data burst responsive to a t.v. line counter (ZZ) causing the change-over switch (TtU) to connect a sender (S) with that buffer store (VTCO). Groups of teletext picture frames are thus sent out at intervals, and there are often also empty teletext picture lines. This unused capacity may be utilised for transmitting digitised audio signals at the compressed bit rate of 36 Kbit per second. At a teletext subscriber station (T1n) the receiver (E) normally feeds the digitised and compressed audio signals into a buffer (P) which gives out the data at a slower rate into a d-a converter to a loudspeaker. The input to the buffer is interrupted when a new teletext frame is selected via a code responsive switch (UTt) to receive the frame video data into a recirculating store (VT Dec).

Title: Test of boiling water reactor control rods - with portion of fuel elements removed and remainder held fixed
Inventor: KARGER LUDWIG
IPC: G21C19/19
Filed: 1980-07-21
Abstract: Method of testing a nuclear reactor core, esp. of a boiling water reactor, for satisfactory control rod run-in, comprises fully retracting (esp. downwards) the cruciform control rods from their positions between each set of four square fuel elements (6). Before each cruciform rod is removed, one or two of these fuel elements (6) is removed from the corresponding square mesh (3) of the core lattice to prevent the core becoming supercritical during the absence of the control rods. The two remaining, diagonally opposite fuel elements (6) are held in place after removal of the other element or elements (4) by holding their top ends fixed by a support component (21) mounted in the mesh (3). Pref., this support component (21) fits over the lifting handles (7) of the two diagonally opposite elements. Pref. at the centre of the pattern of four elements, the support component comprises sPacer blocks (26a, 26b) which fit onto the corners of the remaining elements and have spaces for the other two elements to enter. Used esp. for initial testing of all the control rods of a reactor simultaneously by running them into the core. The initial expenditure of a number of dummy elements equal to half the elements in the core is saved and repeated trial runs can be carried out during the operating life of the reactor, without the need to store large radioactive dummy elements.

Title: Indexing attachment, in particular for tooth-flank grinding machines
Inventor: EICK KURT
IPC: B23Q16/06
Filed: 1981-02-14
Abstract: The invention relates to an indexing attachment, in particular for tooth-flank grinding machines which work according to the single indexing method, in which indexing attachment a defined number of revolutions of the indexing shaft are converted into a corresponding indexing-table rotary angle. The purpose of the invention is to increase the working productivity without adversely affecting the indexing accuracy. The object of the invention is on the one hand to keep the angular accelerations occurring during the indexing operation within predetermined values and on the other hand to realise a very high angular velocity for achieving a short indexing time. According to the invention, this is achieved by the positive-locking connection between an adjustable drive system and the indexing shaft and the change gears, the ratio of drive-shaft revolutions to indexing-shaft revolutions per division being a rational number, and the drive system performing a selectable integral number of revolutions with an angular-velocity profile per division predetermined by an adjusting unit and dependent upon the rotary angle. <IMAGE>

Title: Hydraulic control device
Inventor: SCHWERIN GUENTHER
IPC: F15B13/02
Filed: 1981-10-16
Abstract: The invention proposes a hydraulic control device (10) with a directional control valve (12) and an associated changeover valve control (14) which, with the aid of restrictors (23, 25, 30), makes possible fine control without notable pressure excesses in the fine-control range. Connected upstream of the changeover valve (14) is a third restrictor (30), which is connected in parallel with a second restrictor (25) in the feed (15) and enlarges the control pressure drop, caused by the changeover valve, as a function of the increased residual flow via the changeover valve. This leads to shallower flow characteristics (72) as a function of the spool stroke (s) of the control spool (45) and hence to better fine control. <IMAGE>
