Title: Effect yarn mfg.
Inventor: RATTI ARTURO
IPC: D02G3/34
Filed: 1987-04-08
Abstract: For continuous mfg. of a thermally fixed effect yarn, the separate yarns (A,B,C) comprise at least one core yarn (A) and the two effect yarns (B,C) and they are fed (1,2,2') pref. under electronic control, through a random program so that they are laid and overlaid along the core at different speeds to give the colour effects.  A connection (3) can give alternating designs and fancy effects between the yarns. A bobbin (4) is carried by a central spindle (5), with a central drilling as a passage for the core yarn (A) or the effect yarns (B,C), while the bonding yarn (6) is drawn off the bobbin (4). The false twister (7) is at the outlet of the spindle (5) to give a false twist between the core yarn (A) and the effect yarns (B,C) together with the bonding yarn (6), and prevents any loosening of the false twisting effect downstream of the false twister (7).  A further feed (8) is at the outlet of the false twister (7).  The effect yarn is thermally fixed in a heater (9), and downstream of the heater (9) the feed operates at a speed according to the emerging speed of the yarn from the false twister (7) to control the yarn speed as it passes through the heater (9).  The appts. also has a lubricator (11) and a winding bobbin (12) for the finished yarn.

Title: Transient recorder which digitises fast signal sequences and stores them temporarily in a RAM
Inventor: SMOLARCZYK GERHARD DIPL ING
IPC: G01R13/06
Filed: 1987-07-27
Abstract: The invention describes a transient recorder, in which the memory is addressed via a fast synchronising counter which can be loaded in parallel. For recording data, i.e. for storing signals, the counter generates the addresses. For reading data, i.e. access to the data by the microprocessor, the address bus of the microprocessor is switched to the memory via the parallel loading function of the counter. The higher-value addresses are then passed on via a port, so that the memory area is extended.

IPC: B21D39/06
Filed: 1987-08-06
Abstract: The invention relates to a device for fixing one or more parts (10, 11), each provided with an opening, on a hollow body (1), the opening in the parts (10, 11) being larger in the initial condition than their fixing points on the hollow body (1) and the parts (10, 11) being brought into the predetermined position on the hollow body (1) before the fixing operation is performed by expanding the hollow body (1) at least in the region of the fixing point by means of a pressure medium which is introduced through a probe (12) insertable into the hollow body (1). Arranged on the surface in the probe (12) are pairs (13) of sealing rings corresponding to the axial extent of the respective part (10, 11) to be fixed. In order to avoid unwanted expansion of the hollow body (1) outside the actual fixing areas, the areas of the hollow body (1) between adjacent pairs (13) of sealing rings are relieved of the pressure of the expanding pressure medium. For this purpose, the probe (12) is, on the one hand, provided with in each case at least one relief passage (12c) between the pairs (13) of sealing rings. On the other hand, the hollow body (1) can be provided in the region between the fixing points defined by the pairs (13) of sealing rings with in each case at least one pressure relief opening (14). <IMAGE>

Inventor: COOTE NIGEL CHARLES TRUEMAN
IPC: G01S13/70
Filed: 1987-10-24
Abstract: A radar system for altitude determination comprises a pulsed radar transmitter and receiver having means for adjusting the transmitted pulse width and receiver bandwidth as functions of a detectable search/track height, and means for varying the value of a bias factor relating to an equilibrium tracking condition and for varying count boundaries of a status counter for an integration relating to a tracking lock condition as functions of the detected search/track height whereby the sensitivity of the radar system is improved over conventional altimeters at higher altitudes. The tracking loop determines whether the average power detected at a "signal" sample point (which, in the steady state, will be on the leading edge of the echo) exceeds the power at a "noise" sample point by the height-dependent bias factor. The lock indicator monitors power at a further, "status", sample point. <IMAGE>

Title: Method and apparatus for detecting microorganisms in body fluids
Inventor: SCHAMBACH MARTIN
IPC: C12Q1/04
Filed: 1987-12-28
Abstract: The invention relates to a method and an apparatus for detecting microorganisms in body fluids in human and veterinary medicine, in particular in blood, urine and CSF. The object is to develop a method in which time and distance of a single withdrawal of a body fluid until exposure thereof to liquid or solid nutrient media are minimised and different microorganism cultures are produced simultaneously. The apparatus is to be designed as closed withdrawal/culture system whose construction by the modular principle ensures universal use without preparation. The method according to the invention is characterised in that, after insertion of a needle, any desired body fluid is sucked into a closed withdrawal/culture system, flows into two or more vessels in metered quantity by breaking one or more glass tips successively or simultaneously, is mixed with different liquid nutrient media, and the latter are used to inoculate solid nutrient media, and in that subsequently cultures of different microorganisms are produced and visualised simultaneously or successively. Two or more withdrawal/culture systems with breakable glass tips are connected via a distributor to a common hypodermic needle. <IMAGE>

Title: Spark gap (surge arrestor, series gap) which can be triggered
Inventor: BEERWALD HANS DR
IPC: H01T2/00
Filed: 1987-06-25
Abstract: The invention relates to a spark gap which can be triggered and which has one or more spark channels which are located between the electrodes (1, 3) and are initiated by means of auxiliary electromagnetic energy, especially for switching heavy currents in surge circuits. In order to be able to ignite a very large number of spark channels virtually simultaneously in the case of such a spark gap with a very widely variable operating voltage, the invention proposes that the electrodes (1, 3) be constructed as a waveguide system which produces one or more spark flash-overs when a high-power microwave pulse is injected, which flash-overs initiate spark channels for the main circuit. <IMAGE>

Title: Tube-shaped winding core for thin web-like winding material
IPC: B65H75/10
Filed: 1988-03-31
Abstract: It is known to wind thin web-like winding material, for example sheet-metal material of small thickness or metal foils, onto tube-shaped winding cores which consist of numerous plies adhesively bonded to one another and consisting of webs of paper or of cardboard and of which the covering web forming the outer circumferential surface consists of a flexible material, for example a textile material. However, such covering webs can have irregularities, and this can cause damage to the delicate winding material. To eliminate these disadvantages, in the winding core according to the invention the flexible outer circumferential surface is formed from paper 13 lined with a foam layer 12 or alternatively from a flexible paper lined with a plastic layer. The foam layer or plastic layer is always arranged on the outside. <IMAGE>

Title: Measuring range switch for the automatic setting of measuring ranges
Inventor: SCHULZE WOLFGANG
IPC: G01R15/08
Filed: 1988-04-22
Abstract: Conventional measuring range switches use controllable relays which switch in voltage divider resistors determining the measuring range for automatically switching over the measuring range. It is the object of the invention to create a measuring range switch which can be largely accommodated in an integrated circuit. In each case one of the divider voltages picked up across the voltage divider resistors (R21, R23) is supplied to the base of a switching transistor (Q12, Q18) operating as emitter follower. All emitters of these switching transistors (Q12, Q18) are connected to a common output resistor. At the base of each switching transistor (Q12, Q18), a control transistor (Q13, Q19) is connected by which, in dependence on signals of a control circuit, which are present at its input (11, 14), only the switching transistor (Q12, Q18) which is allocated to the in each case predetermined measuring range is not connected to inhibiting potential. The invention can be used in instrumentation in multimeters and oscilloscopes. <IMAGE>

Title: Method and reflection localisation system for searching for objects on the surface of the sea
Inventor: SCHOTTELIUS HORST-ULF
IPC: G01S17/06
Filed: 1988-05-27
Abstract: A method and a reflection localisation system (11) for searching for objects on the surface of the sea (12) such as, in particular, sea mines (24) which have floated to the surface is intended to be designed for the purpose of enabling unambiguous localisation of such an object using existing and proven components from reflection localisation technology, even in unfavourable visual, sonar and radar conditions. The solution is based on the fact that the emitted infrared energy from a laser localisation system is virtually completely absorbed on the surface of the sea (12) while, in contrast, it produces considerable reflections from objects floating on the surface (12), such as mines (24) having a metal or plastic housing for example, which reflections can be received and can be displayed on a visual display unit (20) as a function of the instantaneous scanning orientation of the transmission beam (15), in order then to move to this position and to destroy a mine (24), which has possibly been detected there, by firing at it. <IMAGE>
Patent DE-3822574-A1 (DE)
Inventor: LEHNERT FRANZRUDOLF
IPC: B64D11/06
Filed: 1988-07-04
Abstract: A seat or chair especially for a flight attendant in an aircraft has a backrest section and a seat section hinged to each other and to a frame in such a way that the backrest section and the seat section can take up different angular positions relative to each other and relative to a vertical frame or to the horizontal. Thus, the chair can be folded to take up several positions including positions in which the seat section takes up lower or higher elevations above the floor. For this purpose the upper end of the back rest section is pivotally guided in a guide mechanism while the lower end of the backrest section is journalled to the rear portion of the seat section at a journal axis which simultaneously forms the journal axis of a support and guide member also hinged to the seat section. The support and guide member is hinged intermediate its ends to the frame through a fixed journal so that the rear edge of the support and guide member can engage a stop in the frame. The guide mechanism at the upper end of the frame permits a tilting motion and a linear sliding motion of the upper end of the backrest section. Thus, the seat section, the backrest section, and the support and guide member together form a type of crank drive. Several positions of the chair may be adjusted, including a lower seat position in which the seat section is slanted relative to the horizontal for an increased comfort.
