Patent DE-2903911-A1 (DE)
Title: Blood corpuscles counting device - with microscope and diode matrix feeding electronic processor
Inventor: PIFFL ERNST
IPC: G06M11/00
Filed: 1979-02-02
Abstract: A device to count the red and white blood corpuscles in a prepd. blood sample consists of a photooptical and an optoelectronic part, with an electronic processor. The photooptical part includes a semitransparent mirror and a set of lenses and prisms. The optoelectronic part is a diode matrix in a CCD-array. The processor converts the light signals recieved by the diode matrix and passed on in the form of voltage signals and indicates the number of blood corpuscles in the field of vision on a display. This makes blood count devices available to a wider circle of users.

Title: Air stream massage appts. with fan and heater - has control housing with switching devices supplied by three-phase cable short circuit
Inventor: BUCHER HEINZ
IPC: A61H33/02
Filed: 1979-05-23
Abstract: To provide adequate safety for the use of an air stream massage appts. which is normally used in a bath, an isolating transformer is usually provided. However, this is bulky and adds to the cost. A special safety cut-out is instead used in this appts. A three-phase mains switch may be operated manually. However, it is switched off automatically when a solenoid is energised by a monitoring circuit, which consists of two coils, one in the life and the other in the neutral line with normally equal currents through both coils. If the current in one coil is not exactly equal to the current in the other coil, energising current flows via coupling coil to the solenoid. A test button is provided which, if pressed, adds a small current to one line which should operate the switch.

Title: Heart pacemaker stimulating electrode - incorporates supporting coil with closely wound ends and loosely wound intermediate part
Inventor: GRIGOROV SERGEI SEMENOVITSCH
IPC: A61N1/05
Filed: 1979-08-10

At the transition points (18, 19) between the closely wound and loosely wound parts, may be a few turns which are wound at an intermediate tension.
Patent DE-2939751-A1 (DE)
Inventor: REMPKE WILFRIED DIPL ING
IPC: G03B9/10
Filed: 1979-10-01
Abstract: The control diaphragm (4) can be driven in such a way that the instant of possible coincidence of the sector cutouts of moving diaphragms is shortened by rapid pivoting into and out of the beam path. It is possible to do without an additional selective diaphragm. Sector-shaped turns (6) are designed as printed conductors leading radially outwards. A connection (7) constructed in a spiral shape serves to supply power. An optoelectronic coupler (10) monitors the position of the control diaphragm (4). The control diaphragm (4) is located partly in the air gap of a permanent magnet (9). When the sector cutouts of the moving diaphragm have reached the diaphragm space (3), the control diaphragm (4) pivots with its cutout (5) into the diaphragm space (3), resulting in an exposure. The rotary disc shutter is applied for the most part in aerial cameras. <IMAGE>

IPC: E01F9/608
Filed: 1980-01-07
Abstract: The hollow section of synthetic material is particularly intended to be used as a guiding road stone. It has a mantle (24) formed by two layers. The outer layer (22) is comprised of a thin wall and carries coloured pigments, adapted for the contemplated use. The inner layer (20) is several times thicker than the outer layer, is black pigmented, preferably by means of carbon black, so as to present a high stability to ultraviolet radiations, to form a core providing the section resistance and also allowing a desired outer coloration. The hollow section may be extruded into two layers. The inner layer of the mantle (20) may be integral with two reinforcement cross-bars (30, 32) arranged perpendicularly in a cross inside the section space (28). To make the inner layer (20) visible from outside, the outer layer, of a thickness of about 0.5 mm., may be removed at desired locations.

Title: IC engine fuel mixture prepn. system - has single injector supplying both main and auxiliary combustion chambers (CS 29.8.80)
Inventor: JAHODA STANISLAV
IPC: F02B19/10
Filed: 1980-01-10
Abstract: The system prepares a fuel mixture with different proportions for the main and auxiliary chambers of an engine with a divided combustion chamber.

Title: Toner developer for photocopier - has magnetic pick=up and magnetic scraper to limit thickness of layer applied to carrier
Inventor: TAJIMA HATSUO
IPC: G03G15/09
Filed: 1980-03-07
Abstract: The toner applicator for a photocopier has a reservoir feed (14) for the toner powder and a rotating, non-magnetic roller (9) with permanent magnet cores to pick up the toner and apply it to the process drum. The thickness of toner on the roller is controlled by a scraper blade (10a) held above the roller and made of magnetic material. The toner layer does not touch the process drum and the required amount of toner is transferred to the charge image on the drum by an alternating electric field. The magntic scraper blade is positioned opposite one of the magnetic cores and the resultant field between them is at least 0.135T. The toner is agitated by a stirrer to provide a non-clog feed as well as an even texture. For optimum effect the magnetic content of the toner is between 15% and 50%.

Title: Method and circuit arrangement for processing received pulse signals in acoustic instruments
Inventor: KRAUSE GERHARD
IPC: G01P5/24
Filed: 1981-03-12
Abstract: In a method and a circuit arrangement for processing received pulse signals in acoustic, electronic and/or optical instruments, acoustic or electromagnetic pulses are sent at time intervals through a measuring system containing a flowing medium. From the transit time of the pulses, a particular characteristic of the medium which depends on the sound or wave velocity is inferred. To achieve a very significant reduction in the influence of the large fast fluctuations of the transfer factor on the position of the front edge of the received pulse signal in time, the instantaneous value of the received signal is compared at any instant with the instantaneous value of the same received signal received earlier by a fixed time difference. The output signal is supplied when the ratio of the two signals exceeds a predetermined amount. <IMAGE>
