Title: Reclosable bag prodn. method - using closure bands with stiffener insert made from metal or plastics
Inventor: LARSSON STIG ERIK RAGNAR
IPC: B31B1/90
Filed: 1975-09-30
Abstract: Production method for reclosable bags which have closure band containing a stiffener insert projecting over the width of the bag at its upper end. The bag and the closure band are produced simultaneously but separately and are subsequently combined. The closure bands are produced from two tracks of continuous bands made from a thin foldable material with the insertion of stiffening inserts made from metal, plastic etc., at pre-determined intervals. The continuous band is cut off crossways at points located between the stiffening inserts and the cut off closure bands are then attached with an adhesive at points of the bags arranged for it. The machine (2) to produce the closure bands has two rollers (11, 12) of the support material of a width corresponding to the length of the closure bands being produced and an installation (13) to cut off the stiffening inserts (36).

Title: Continuous sepn. of oil-in-water emulsions - by ultrafiltration with subsidiary oil separator working in parallel
Inventor: PREEN WOLFGANG VON DR ING
IPC: B01D61/14
Filed: 1975-10-17
Abstract: The process uses semipermeable membranes for ultra-filtration. The membranes are permeable w.r.t. water molecules and impermeable w.r.t. oil molecules. In the novelty, a subsidiary stream of the emulsion is removed from the holding tank and a large proportion of the oil is sepd. from this subsidiary stream in a process operating in parallel with the ultrafilter. The subsidiary separator may employ chemical, physical or chemico-physical sepn. techniques. The residual emulsion is returned from the subsidiary separator to the common holding tank. Continuous operation is ensured with less equipment than is required by prior art process employing subsidiary sepn.

Title: Perfluoro-carboxylic acids prepd. from perfluoro-alkyl olefins - by reacting with ozone followed by oxidn.
Inventor: UKIHASHI HIROSHI
IPC: C07D323/02
Filed: 1975-12-17
Abstract: Perfluorocarboxylic acids (I) are prepd. by (a) reacting a perfluoroalkyl olefin to produce a perfluoroalkyl ozonide and a perfluoroalkyl aldehyde and (b) converting the ozonide and aldehyde to (I) with an oxidising agent. (I) are obtd. in high yield and have high purity, without the use of highly corrosive agents. The process does not form solid by-prods. which are difficult to separate and can be used for large scale prodn. (I) are used as vaporization suppressants for volatile combustible organic liquids. Their ammonium salts and alkali metal salts are emulsifiers for the polymerisation of fluorinated olefins. (I) are inters. to fluorocarbon surfactants having excellent surface activity and certain metal salts and polymers dervied form (I) are useful water-repellent and oil-repellent agents. The oxidising agent may be ozone, H2O2 or a peracid. In an example, C8F17CH=CH2 was reacted with ozone at 50 degrees C for 3.5 hrs. The reaction prod. was oxidized with H2O2 to give a 92% of C8F17COOH and 8% of C7F15COOH.

VIB metal and halogen supported on silica-alumina or a symt synthetic or natural gaugasite) at 300-646 degrees C and >400 psig with an H2: oil ratio of 4-50:1 and for 1-180 secs., conditions being so selected that a 2-5C product is obtained in a 91-95% yield and with an n-paraffin isoparaffin ratio of >3:1, (2) separating the hydrocracking effluent to recover a 2-5C alkane product, and (3) thermally cracking the 2-5C alkane fraction to produce ethylene and propylene as co-products. Olefin yields of 50-60 lbs/100 lbs feed are obtained (c.f. 30-35 lbs. by the thermal cracking of gas oils). The 2-5C product with its high (3-6 1) n-paraffin ratio can be used as a replacement for l.p.g. as a feedstock for existing ethylene plants.

Title: Undersurface heating for roads using heat transfer fluid - which abstracts heat from warmer environment by natural convection
Inventor: RICHTER DIETRICH
IPC: E01C11/26
Filed: 1976-03-03
Abstract: A heating system for road pavements consists of embedded pipes or hoses, through which a heat-emitting fluid flows. The piping system in the road surface is connected by feed and return lines to a second system of pipes of hoses located in an environment at a higher temperature; a heat transfer medium flows by natural convection through the entire system. The heat transfer medium is of type which exhibits a charge of state between the liquid and gaseous states in the two temperature regimes encountered. More specifically, the heat transfer medium may be a freon, or an azeotropic mixture of methyl propylene glycol and water. Used for any type of road heating where ice or frost is particularly liable to form, more specifically for such regions as bridges, where the adjacent ground, a body of water such as a river or the like can be used as the heat source. The arrangement enables the operating costs to be kept to an absolute minimum since there is no heat input and no pumping is required.

Title: IC engine ignition variables monitor - detects average of ignition voltage using three switches and two storage capacitors
Inventor: BLUM RUDOLF DIPL ING
IPC: F02P17/12
Filed: 1976-08-19
Abstract: The monitor, for the ignition variables e.g. average ignition voltage of an IC engine, has a first storage capacitor (18) switched (20) to a second storage capacitor (21) to pass its stored charge (resulting from rectified ignition voltage peak) to the second capacitor.

Title: Tunnel kiln for firing ceramic prods. contg. combustible - uses co-current flow in preheat and part of fired zone
Inventor: HAESSLER ANDREAS ING GRAD
IPC: F27B9/36
Filed: 1976-11-23
Abstract: Operation of a directly fired tunnel kiln is for firing ceramic prodt. emitting harmful materials. The preheat zone and least part of the combustion zone are operated in co-current. The waste gases in the hot zone are taken from the combustion channel into the flue. In the preheat zone, heating and recirculation devices are installed. Heat from the cooling zone is used heat the preheat zone. The co-current motion in the preheat heat and combustion zones is carried rhythmically in the axial direction of the funnel. At the kiln inlet are located volume balancing devices to take up the axial to and fro motion of the gases. Any toxic materials emitted by the fired objects are carried by the gas towards the hot zone. Used with ceramic objects which are mixed with combustible materials to form a light structure, e.g. light tiles - by mixing with finely divided combustible materials such as sawdust, polystyrene, peat etc.

Abstract: The malfunction display unit consists of a transparent drum driven by an electric motor, switches which monitoring working conditions being fitted inside the drum. Each switch has a projecting push rod held by a spring in a rest position and completing a circuit for the monitored condition. When a malfunction occurs the circuit is broken and the push rod is pressed outwards by the spring. The outwards movement of the push rod completes a second circuit causing the electric motor to rotate the drum. The drum has a cam fitted to its inner surface which strikes the projecting push rod, pressing it inwards and causing the motor to stop. A display lamp indicates which switch has opened and gives an appropriate remedy suggestion.
