Title: Sliding clasp fastener mfg. - has core between tooth legs bonded to carrier for added lateral strength
IPC: A44B19/40
Filed: 1980-08-22
Abstract: At least one textile packing core (12) runs along the line of teeth, for the sliding clasp fastener, passing between the upper (6) and lower (7) legs. The cores (12) are held by the rear locking sections (9) on one side, and by the bonding warps (3a) on the other side. The core (12) is compressed by the legs (6,7) of the fastener teeth, to run straight on an orthogonal plane as a projection of the plane of the sliding clasp fastener. The core (12) line is corrugated, through the pinching action of the teeth legs, with the top of each curve between the legs (6,7) and the base of each curve between the teeth (2), and passing under the wefts of the carrier strip as it lies between the teeth. An additional double weft is provided in the carrier strip fabric, to pass between the teeth (2) for bonding, so that both double wefts lie together in a common warp pocket. The structure increases the strength of the mounting for the fastener teeth to the carrier strips, partic. resisting lateral pressures when the sliding clasp fastener is distorted.

The liquid from the turbine is integrated in a thermal circuit, incorporating also the radiators (5) or other heating elements for the rooms concerned. The hot liquid circulation is activated by the pumping action of the turbine.

Title: Horizontal nip padding assembly - has boundary-layer separator in front of nip to improve padding efficiency
IPC: D06B1/14
Filed: 1980-12-22
Abstract: A nip padding mangle comprising a pair of rollers in a horizontal plane for impregnating textile material with a fluid which is contained in the valley between the two rollers has a device for separating the boundary layer of air from the fabric immediately before it reaches the padding zone. The sepg. device consists of a suction nozzle or a doctor blade extending across the full width of the material and in close proximity to the surface on one or both sides of the material. The device counteracts the reduction in wetting speed at high material feed rates by removing the boundary layer which prevents rapid contact between the fluid and the material in high-speed operation, and enables high processing speeds to be employed without loss of wetting efficiency.
Patent DE-3048979-A1 (DE)
Title: Electrostatic filter for removing dust from gas - maintains dust conc. constant by regulating HV
Inventor: VOGLER ALFRED ING GRAD
IPC: B03C3/68
Filed: 1980-12-24
Abstract: The electrostatic filter consumes relatively little power and maintains a minimum purity of outgoing waste gas and smoke from smelting processes. The instantaneous concentration of dust in the clean outgoing gas is measured and the filter's high voltage adjusted so as to keep the concentration roughly constant. The voltage is increased if the dust concentration increases and reduced if the concentration reduces. The filter consists of several filtering stages. The stages are controlled individually so that the filter's performance increases in steps. Sensors measure the flow rate of the waste gas and its temp. as well as its dust concentration. All the sensors control the high voltage.

Title: Doser for fine:grained, flowable powder - esp. for feeding alumina from silo into electrolysis cell contg. molten cryolite and used for mfg. aluminium
Inventor: REBMANN HANS-JOERG
IPC: C25C3/14
Filed: 1980-12-30
Abstract: The doser consists of a vertical guide tube formed by an inner tube(a) located in an outer tube(b) inside a silo. Both tubes, (a,b) have inlet holes, so powder in the silo can enter tube(a). In tube(a) is a piston rod driven by a pneumatic cylinder, and carrying a piston above a conical stopper. The stopper closes the bottom end of tube(a) while the latter is filled with powder. The piston rod is then lowered so the powder falls out of tube(a) while the piston closes the inlet holes. The piston is longer than the inlet holes and is formed by a wire brush. The powder pref. drops into a distributor pipe. The doser is inexpensive and reliable, and requires only a small amt. of space. -.

Title: Method and device for wrapping a pile of packaging products with stretch film
IPC: B65B11/04
Filed: 1981-01-09
Abstract: A method for wrapping a pile of packaging products with stretch film, in which the pile is turned relative to the holder of a roll of film and the roll of film is braked to tension the film, the braking effect being delayed relative to the beginning of winding. The method allows a higher braking force and film tension due to the fact that the braking effect is gradually increased from a low initial value. A machine for carrying out this method has a brake whose switching-on device is set up in such a way that the braking effect is gradually increased.

Title: Colouring of transparent polymer materials by diffusion, and their use in light-concentrating and light-conducting systems
Inventor: WITTWER VOLKER DIPL PHYS DR
IPC: D06P1/00
Filed: 1981-02-05
Abstract: The invention relates to a process for the colouring of light-collecting systems, comprising layers of polymer materials doped with a fluorescent dye. Introduction of the dye into a transparent polymer is disadvantageous according to known processes due to thermal loading and chemical attack on the dye. It is proposed according to the invention to introduce the dye into the transparent material by diffusion from the solution or from the gas phase. This makes it possible, through, for example, a suitable choice of temperature, to establish dye concentration profiles.
