Title: Spirally wound, absorbent tampon for feminine hygiene - has recovery thread running diagonally to prevent disintegration of layers
Inventor: SNIPPE WALTER
IPC: A61F13/22
Filed: 1976-03-24
Abstract: A pressed, rodlike, wound tampon has an absorbent body of cotton or cellulose wool, through which a recovery thread in the form of a loop passes diagonally. The two legs of the recovery thread penetrate the base of the tampon in the zone of the largest dia. and the cross piece joining the two legs lies either on the circumference close to the front face, or in the front face outside the zone of the largest dia. The tampon which cannot unwind when satd., is produced without additional means such as bridging threads through the windings. The thread passes diagonally across a number of layers of the wadding spiral and thus holds them together.

Title: Flow behaviour of blood or serum determination - uses suction of liq. through capillary with feedback through it at constant speed
Inventor: WEBER GERHARD PROF
IPC: G01N11/04
Filed: 1976-03-27
Abstract: The liquid from a human body or any other vessel, is sucked into a storage section (5) through a measuring section (2) with a capillary (3). In order to measure its viscosity, the liquid is then passed back through the measuring section at a constanct velocity during a certain time interval. Preferably the suction and feedback passage are carried out by means of an auxiliary liquid, such as an infusion solution. The suction of the examined liquid is carried out until the infusion solution reaches the suction and/or pressure device, with strict exclusion of the measured liquid from the apparatus proper.

Title: Noise isolated mounting for fluid pipes - uses elastomer type isolating ring located in housing clamped by mounting bracket
IPC: F16L55/02
Filed: 1976-06-29
Abstract: An isolated mounting, particularly suited to water pipes in residential buildings, reduces the transmission of noise through the building structure. The isolator consists of an annular ring (6) of an elastomer type material with a number of grooves (8) on the outer surface. The ring is retained in a housing ring (4) of plastic with retaining lips at either end. Both the isolating ring (6) and the housing ring (4) are split on the circumference to allow easy location on the pipe. Once in position in the bracket circumference pressure is applied by clamping to maintain secure contact of the isolating ring. The split ends of the housing ring may be formed as an interlocking claw that self latches.

Title: Conveyor for handling steel concrete reinforcing rods - has rotor with pockets for transferring rods from shears to conveyor
Inventor: FASHOLZ HANNS
IPC: B21D43/00
Filed: 1976-07-24
Abstract: The steel rods for reinforcing concrete are cut to the required length from a continuous rod which is fed through the guide groove. The rods are ejected by the motion of the lever and fall onto the sloping track and then roll into the pocket of the rotor. When the required number of rods has been cut the jack is actuated so that the rotor rotates through 90 deg.. The pocket then takes up the position of pocket and the rods roll over the track onto the conveyor belt. This shape of rotor enables bundles of rods to be assembled without interrupting the continuous feed of rod to the shears.

Title: Mechanical forging press with two concentric vertical punches - in which outer punch also drives horizontal punches, esp. to mfr. hollow forgings
Inventor: FEIRER EGON
IPC: B30B1/26
Filed: 1976-09-10
Abstract: Mechanical forging press, esp. for the hollow forging of metal workpieces, steel fittings etc., where the workpiece blank is held and possibly preforged by a vertical inner punch located concentrailly inside an outer ring punch driven independently from punch. Punch is fitted with wedge-shaped extensions driving side punches inwards when punch is lowered, for forming the outside or ends of the workpiece; instead of the driving wedges, a toggle- or elbow lever drive can be used to actuate punches. All the punches are operated mechanically; and punches work in a horizontal direction, i.e. at 90 degrees to the vertical movement of punches. Punches are in contact with the workpiece for a min. amt. of time, so their working life is increased.

Title: Tool for preloading electrical contactor leaf spring - has spring drawn through inclined jaws for permanent deflection corresponding to preload
Inventor: AWAKOWICZ ERWIN
IPC: B21D53/88
Filed: 1976-09-16
Abstract: The tool for preloading of leaf springs is used esp. for preloading contactor springs. The springs are permanently deformed by bending out of their initial plane along the longitudinal axis. The leaf springs are preloaded with narrow dispersion of the required forces. A spring is drawn longitudinally in its initial plane at least over part of its length through a gap with flat jaws (6, 7). The spring rate is individually measured before the drawing process and the spring defection necessary for the required preload is calculated from this measurement. The permanent deformation(s) of the spring is influenced by modifying the angle of inclination of the drawing jaws.

Title: Location of triggered sensor in alarm system - by measuring peak voltage at end of line of series connected sensor contacts having parallel connected resistors
Inventor: EBERHARD DIETER
IPC: G08B25/01
Filed: 1977-04-14
Abstract: An alarm system with multiple sensors is designed to provide the central control with an indication of the location of any triggered sensor. The sensors have contacts K1, K2-K14) coupled to a measuring point (M) with a constant current supply (1). Resistors are connected across the contacts so that when a pair of contacts parts their position can be identified by the voltage at the measuring point. A peak rectifier (2) operates on the signals generated from a sensor being triggered and the rectified signal is held in an analogue memory (3). The stored signal is compared (4) with the output of a D/A converter (5) that is cycled by a counter (6) operated by a multivibrator. When the comparator generates an output the counter state is stored (7) and decoded to provide a location display signal.

Title: Carrier material discs for microorganisms - sepd. for miniaturised multi-test systems by using annular cutting device on substrate
Inventor: MALIK K AHMAD DR
IPC: C12M1/16
Filed: 1977-04-27
Abstract: A device for the manufacture of several carrier material discs for microorganisms from a planr substrate matl. layer, followed by a complete insulation of the carrier discs, consists of two concentric cutting edges which can be used to punch an annulus around the carrier discs from the substrate. A spring-loaded ejector can be used to remove the annulus. This creates a clear local separation of the carrier discs from each other. Standard methods such as multipoint inoculation, viable counts and other multi test systems can now be miniaturised; one normal Petri dish can accommodate nine carrier discs.
