Patent DE-2647212-A1 (DE)
Title: Appts. for removing liq., e.g. scouring solv. from running textile web - by passing hot gas through the web using suction
Inventor: HOLM WILLIAM JARVIS
IPC: F26B13/30
Filed: 1976-10-19
Abstract: A running textile web that has been subjected to soaking by a liquid such as a scouring solvent is carried between a suction box located adjacent one face of the web and a source of pressurised and relatively dry heated gas adjacent the other face thereof and opposite the the suction box. The heated gas passes through the web and is drawn into the suction box, enhancing the amount of liquid removed at this stage and presenting the web into a drying stage with less entrained liquid than if the web were subject to the action of the suction box only. The amount of mechanical mist is kept to a minimum within a closed scouring range using a closed loop between the suction box and a return conduit provided with a trap containing a batt of metallic wool. The liquid discharge from nozzles employed to uncurl the edges of the web is directed against shields also containing a batt of metallic wool to reduce bouncing, noise and mist generation.

Title: Toothed auxiliary support for ceiling fibre boards - is disc with teeth on rim engaging with teeth on board coupling arrangement to prevent bowing
Inventor: MULDER ANTHONIUS GEORGIUS
IPC: E04B9/20
Filed: 1976-11-17
Abstract: The toothed auxiliary support is esp. for fibre boards used in recessed ceilings and prevents bowing caused by creeping which is partic. likely with large mineral fibre boards. The support has at least two teeth with sharp ends. The teeth penetrate the board mounting arrangement. The teeth (2) can be either similar or different. A toothed coupling arrangement is chosen so that when the support (1) is rotated the teeth (2) engage with the board teeth for fixing. Additionally, the circular surface can have two pairs (3, 4) of fixing elements for a T-profile. Furthermore, a central tongue (5) can have a fixing aperture at its end.

Title: Non-dispersive two-beam infra-red gas analyser - has simple compensation of transverse sensitivity of double-layer detector
Inventor: HAMADA TOSHIYOSHI DIPL ING
IPC: G01N21/61
Filed: 1977-01-24
Abstract: A device for compensating the transverse sensitivity in a non-dispersive infrared gas analyser operates by the two-beam method with a double-layer detector arrangement. The rear wall of the second detector chamber is formed as a window which transmits radiation; behind this window, means are mounted for adjustably reflecting back into the second detector chamber a part of the radiation issuing out of it, so that the reflected radiation is equal in respect of the measured radiation path and the compared radiation path. Pref. the reflecting means is a plate with a reflecting surface parallel to the window and slidable adjustable perpendicularly to the plane passing through the central a axes of the two beams. Alternatively, the reflecting means is a plate with a reflecting surface flat against the window an obscuring plate can be introduced between it and the window. The transverse sensitivity can be compensated by a very simple constructed and economical device, capable of use over a wide range.

Title: Flame cutting burner with noise redn. hood - which contains sensor indicating change in static pressure or noise
Inventor: ROEDER GEORG ING GRAD
IPC: B23K7/10
Filed: 1977-03-11
Abstract: Flame cutting machine has a worktable on which the work-piece rests, and >=1 burner with a cutting nozzle surrounded by a noise redn. hood fitted with a sensor in contact with a controller (a) connected to the controller (b) of the machine. The hood can pref. move axially along the burner according to the static pressure in the hood so the sensor operates a switch (a) which has several positions: the burner pref. has longitudinal slots along which the hood can slide. Alternatively, the hood cannot move on the burner, but has a pressure-sensitive nozzle leading to a pneumatic controller (a) feeding signals to controller (b). A third alternative uses a microphone in the hood, connected to a noise level detector (a). Alterations in pressure or noise can be used e.g. to indicate that the burner flame has died or that the burner has reached the end of the workpiece.

Title: Polyesterurethane moulding prodn. - from polycaprolactone and poly:isocyanate using accelerator system with low di:butyl tin di:laurate content
Inventor: SCHAPER HERBERT DIPL CHEM DR
IPC: C08G18/16
Filed: 1977-04-23
Abstract: In the prodn. of polyurethane mouldings based on polycaprolactone of mol. wt. 500-4000, a polyisocyanate, chain extenders and additives, the reaction takes place in the presence of 0.3-4.0% trimethylolpropane (I), 0.005-0.020% dibutyl Sn dilaurate (II) and 1.5-3.5% 33% triethylene-diamine (III). CClF3 or CH2Cl2 can also be added. Pref. up to 50% of the polycaprolactone can be replaced by other polyesters of mol. wt. 500-4000. Ethane diol is pref. used as chain extender. The process can be used for the economical prodn. of integral foams and mouldings made by the reactive casting technique. The accelerator system contains relatively little (II), which had the disadvantage of catalysing the hydrolytic decompsn. of polycaprolactone polyester, whilst (I) ensures that a considerable level of structural strength is obtd. immediately after cure. Good green strength is also obtd., so that complex mouldings can be produced in relatively short times without waste. The low (II) content also prevents hydrolytic ageing during use.

Inventor: KAWAMURA MASANORI
IPC: G09F19/22
Filed: 1977-10-12
Abstract: The fire alarm-operated escape route signal system indicates automatically the possible escape route to the nearest fire exit. It has fire alarm-operated circuits emitting a signal into the wiring system. The signal transmitters switch and distribute incoming signals to the corresponding output terminals. The signal converters are in the vicinity of the fire alarm instrument and are operated by these. They produce a signal change in the wiring system at the point of the signal converter. The escape route indicating equipment indicates the shortest escape direction and route in relation to the direction of the incoming signal.
Patent DE-2746912-A1 (DE)
Inventor: BRAUN ANDREAS DR ING
IPC: G01R35/02
Filed: 1977-10-19
Abstract: To ensure completely automatic determination and indication of the current and voltage errors or, respectively, the phase displacement angles in three error range steps without using conversion factors, an adjustable error-compensated current transformer (T5) is provided, the secondary winding (WF) of which can be switched in decade steps. A reference voltage @ derived from a reference current transformer (T1) or reference voltage transformer excites a digital 90 DEG circuit and generates two squarewave voltages, one of which is in phase with the reference voltage @ and one of which is phase shifted by 90 DEG thereto. These squarewave voltages are used for driving two sequence hold amplifiers (S/H1, S/H2) which ensure that at the time of their application, the voltage error and the phase displacement angle are available as voltage value from the difference voltage @, which is also provided, and the reference voltage @, which are indicated on two mutually independent digital voltmeters (DV1, DV2) at a triggering rate of predetermined clock pulse sequence. <IMAGE>
