Title: Rotary piston pump for conveying air
Inventor: KUELLER GUENTER
IPC: F01C21/08
Filed: 1984-05-21
Abstract: In order to achieve a greater delivery efficiency compared to available models, the rotor is constructed with three slots holding the vanes. As a result, a very large value can be chosen for the rotor/bore ratio. The weakening of the rotor profile thus caused was prevented by means of a supporting ring which absorbs the stresses at the locations at risk. The rotor was constructed as a hollow section, firstly to reduce the weight and secondly to cool the pump interior and the vanes. In order to ensure continuous cooling, a coolant pump has also been incorporated in the rotary piston pump. In accordance with the intended use, inserts are incorporated in the running face of the rotor vanes, in order to counteract wear. To facilitate adjustment of the play between rotor and casing bore, and to achieve as long an overhaul interval as possible, the play can be adjusted by means of adjusting screws.

Title: Circuit arrangement for controlling film advance
Inventor: UFER WOLFGANG DR
IPC: G03B7/24
Filed: 1984-10-27
Abstract: The invention relates to a circuit arrangement for controlling film advance in photographic cameras, which for the preferred use of film cartridges are constructed with electrically readable coding of the film length. The aim and object of the invention is to improve known devices of this type by means of a circuit which despite a low degree of complexity simplifies the film advance up to the rewound state and ensures that damage to the film and winding it back too far are excluded. In accordance with the invention, this object is achieved when use is made of a coding circuit for the maximum number of frames which can be read off electrically from the film cartridge as well as for pulses emitted by a frame counter independently of the direction of film movement, at the outputs of which there is connected a logic circuit for processing signal levels which characterise the maximum possible frame number, the actual frame number, twice the maximum frame number, the zero setting of the frame counter and fixed numbers and which forms the control element for initiating film rewinding when a maximum frame number has been reached, and for stopping rewinding when twice the maximum frame number recorded by the frame counter is reached. <IMAGE>
Patent DE-3445037-A1 (DE)
Title: Mast/sail combination
Inventor: SCHOLZ LUDWIG
IPC: B63H9/08
Filed: 1984-12-11
Abstract: Mast/sail combination for vessels rigged with sails, in which the mast (1), erected on the vessel so as to be rotatable about its vertical axis, is designed in cross-section as a symmetic profile fluidically advantageous in an aerodynamic manner, although this profile ends in a truncated rear edge slightly aft of its widest point. A groove (5) into which the sail battens (2) can be inserted is located in the rear edge of the mast. The opening of this groove roughly corresponds to the thickness of the sail battens; in the interior it is distinctly widened so that the sail battens can change position therein and thereby alternatively form a mutual angle with the profile axis. At the luff, the sail (4) has a mast pocket (3) which is pulled over the mast and is dimensioned in such a way that it forms together with the mast and the sail battens at an obtuse angle thereto an asymmetic, propulsive wing profile on which the laminar flow can bear on both sides and pass into the sail. The advantages of this mast/sail combination lie in the fact that a favourable oncoming flow is guaranteed and no turbulences develop and that, futhermore, as a result of the asymmetric profile, considerable propulsion is produced in the area of mast and mast pocket, and this is in addition to the normal propulsion of the adjoining sail. This means that such a rig produces considerably more propulsion than a rig of the same size of the hitherto known types. A ... Original abstract incomplete. <IMAGE>

Title: Data processing system with improved buffer memory control
Inventor: NISHIMUKAI TADAHIKO
IPC: G06F12/08
Filed: 1985-01-23
Abstract: The invention relates to a data processing system and, in particular, a memory control device for a buffer memory (cache memory) (11) existing in the system. The system can be based on a I/O memory table microcomputer system which exhibits an acquisition circuit (9) which detects whether an access address for a read request generated by a central processing unit (CPU) relates to an area (like a status register in the above-mentioned microcomputer system) within the total memory area which comprises a main memory and the status register, which can be accessed by a further processing unit such as an I/O device (4). If data must be retrieved for a command to be executed by the central processing unit (CPU) and they are not found in the buffer memory (11), the central processing unit (CPU) reads out of the entire memory area. A write circuit (13) writes the retrieved data into the buffer memory (11) when the acquisition circuit specifies that the access address does not apply to the area which can be accessed by the other processing device (4) in the entire memory area. Otherwise, the write circuit does not write the retrieved data into the buffer memory (11).

Filed: 1985-01-23
Abstract: A magnetic head assembly has a slide, an arm carried pivotably by the latter, a spring urging the arm towards the slide, scanning heads, arranged in opposition to each other at the end of the slide and of the arm, for recording and/or reproducing an item of information on and/or from a recording medium, and a carrying element, bearing the spring and having a plurality of pressure-adjusting locations available to it. The pressing force of the spring can be set using the carrying element. Such a magnetic head assembly presses the scanning heads with uniform force against the recording medium, with the effect of preventing any deterioration in characteristic values, for example a change in the output power, and any damaging of the recording medium.

Title: Method and apparatus for determining the concentration or the mass fractions of certain gases in gas mixtures
Inventor: BLOCK FRANZ-RUDOLF DIPL PHYS D
IPC: G01N21/17
Filed: 1985-03-07
Abstract: When using the method for determining the concentration or the mass fractions of certain gases in gas mixtures, the detection of the desired component is effected within a measuring cell according to the non-dispersive opto-acoustic principle using a tunable laser as a light source. Into the split beam path of the laser light source a measuring cell and at least one reference cell containing a known calibration gas mixture are introduced. The opto-acoustic signals are recorded continuously and simultaneously as the laser source is tuned and are compared at the wavelengths at which there are peaks in the reference gases. Based on the various signal intensities, the respective concentration of the gas is finally determined. This method has a particular feature in that by virtue of the simultaneous comparison and a special analysis method it is not necessary to know specific lines or to keep to them.
