Patent DE-2819494-A1 (DE)
Inventor: RAU JOSEF
IPC: F16K13/00
Filed: 1978-05-03
Abstract: The device has a hollow cylinder (6) connected by terminals (7a, 8a), for example, to a suction line between a vacuum pump and a collection tank. The hollow cylinder (6) comprises an axially displaceable piston (10) interacting with a valve seat (9). The piston (10) has continuous longitudinal grooves (11) on its jacket surface. If, then, liquid or foam enters the hollow cylinder (6) the longitudinal grooves (11) are sealed and the piston (10) is forced against the valve seat (9) due to the reduced pressure. In contrast to a float valve this device also prevents throughflow of foam. The device can be used especially in medicine for suction drainage where the liquids (blood and secretions) sucked off an operation wound have a strong tendency to foaming. <IMAGE>

Title: Monitor for increased security signalling lines - has receiver which sends time signals to transmitter, with disintegrated identification word
Inventor: ZIERER JOSEPH DIPL ING
IPC: H04L1/18
Filed: 1978-05-06
Abstract: The monitoring is performed by consecutive, repeated transmission of signal words representing the state of a transmitting station, and identifying it. Time signals are transmitted by the receiver station to the transmitting station in a random sequence. The transmitter stops the transmission of the current signal word, and resumes its transmission from a specified point of the word. The signal messages relate to such external influences as air pressure, temperature and moisture content.

Title: Continuous small section steel or wire rolling - using high redn. initial rolling mill for longer flying welding rig pauses
Inventor: PETEREIT LOTHAR
IPC: B21B1/20
Filed: 1978-08-19
Abstract: System uses long round or octagonal billets which are welded together by a flying set including a welding and a deburring rig. Before the billets are passed to the rolling mill stands they are reduced at a high redn. ratio in a high redn. rolling mill stand, pref. a planetary skew mill being used. The semifinished prod. then passes to the main rolling mill or wire drawing installation. The slow intake speed of this high-reduction stand creates the necessary time interval, needed for the flying welding/deburring set and its return stroke.

Title: Exhaust gas cooler for IC engine - has compressed gas reservoir and injection nozzle for cleaning gas passage
Inventor: LAMMERS BERNHARD
IPC: F01N3/04
Filed: 1978-09-20
Abstract: Exhaust gas is discharged into a coller in which it is cooled by indirect heat exchange with water before being discharged to atmosphere. A nozzle projects into the exhaust pipe just after it enters the cooler. The nozzle is connected to a regulating valve which is connected to a compressed air reservoir. The reservoir has a filling connection with a stop valve. After the reservoir is charged with compressed gas the regulating valve is adjusted to blow gas through the exhaust pipe to dislodge solid particles of dirt which may have settled after being condensed out of the exhaust gas.

Title: Belt clasp mechanism with detachable fixing parts - has belt ends wrapped round clasp and held by clamping action
Inventor: PARSOT JON
IPC: A44B11/12
Filed: 1978-09-26
Abstract: The firt part (1) of the clasp has a frame with first, second (7) and third (8) spaced parallel transverse webs. They are designed to guide the end section of the belt or the like so that it runs round the first web to rest thereon and form a loop whilst the sections of the belt following the loop lies one on top of the other to run through between the second and third webs (7, 8). The first end section is thus held by frictional forces whilst the following second part (2) of the clasp holds the second end section of the belt by clamping action. The clasp now has a detachable connection with the belt ends with no rivets etc. and so can be replaced when required.

Title: Facade element for solar heat collection - with cantilever reflector surmounted by transparent panel for better radiation utilisation
Inventor: KOESTER HELMUT DIPL ING
IPC: F24S23/77
Filed: 1978-12-02
Abstract: Facade elements for solar heat collection on the wall of buildings consit of a vertical plane receiver, an inclined transparent surface which extends from the top of the receiver to a slightly upward inclined reflector with a mirror foil. The latter also reflects the solar radiation back to the receiver. A roller blind between the receiver and a vertical plastic foil protecting it has on the side towards the receiver an infrared reflecting coating and on the opposite side a light radiation reflecting coating. When the roller blind is drawn down to cool the building wall in summer, the solar radiation is reflected by it to absorber tubes, carrying a heat transport medium, which are fitted to the inclined reflector. The pref. material for the transparent parts of the facade elements is acrylic glass or PVC and for the frame components it is aluminium or rigid PVC.

Inventor: DILO RICHARD
IPC: D04H11/08
Filed: 1979-01-11
Abstract: The invention refers to a method for the production of velour needlefelt webs by processing a fiber fleece bonded through needling, using velour or fork needles forming pile loops. At least one fiber fleece band which consists of several layers is helically wound to form a tube which continuously develops in an axial direction. The tube rotates about its own axis, wherein the individual layers of the fleece band partly overlap on each wind and the lower or inner-lying layers of the wound tube are bonded in a width which is smaller, preferably up to half the width of the width of the fleece band in a known manner using felting needles and from the upper or outer-lying loose fiber layer of the wound tube, the fibers forming the pile loops are pushed through the pre-bonded lower or inner-lying fiber layer in a known manner using fork needles. The finished processed tube is cut open in the axial direction, said flat and the so-formed material web is wound up. sp This is a divisional of a previous application Ser.

Title: Reserve effect on cellulose with reactive dyes - reacting by addition, using cyclic di:carboxylic acid imide as reserving agent
Inventor: ONG SIEN LING DIPL CHEM DR
IPC: D06P5/12
Filed: 1979-02-27
Abstract: A reserve effect on textiles of cellulose fibres is achieved with reactive dyes by using as reserving agent a cyclic dicarboxylic acid imide (I) esp. phthalimide or succinimide. Reserving compsns. contg. (I) plus usual auxiliaries are also new. (I) react selectively with dyes (A) reacting by addition, but have no effect on dyes (B) reacting by substitution. They are thus esp. useful in (multi)colour reserve printing, but can be used for white-reserving printing if only type-A dyes are present. The method is simple and reproducible and allows a wide range of colour effects to be achieved. The textiles may be of natural or regenerated cellulose or cellulose acetate.
