Abstract: Epoxy resin compsns. with extended pot life comprising (a) polyepoxy cpds. (b) anhydrides of polybasic carboxylic acids and (c) 0.001-3% (esp. 0.5-1.5% of barbituric acid, thiobarbituric acid, or N-substituted or nitration- or nitrosation products of these, as retarder. Preferred retarder (c) is (thio)barbituric acid, opt. substituted with 1 or 2 alkyl or aryl grps. such as methyl, ethyl, butyl or octyl grps. The new retarders are particularly effective with mixtures of crystallised glycidyl isocyanurate and anhydrides; they may also be used with cycloaliphatic epoxy resins such as the glycidyl ester of hexahydrophthalic acid, or with conventional epoxy resins based on polyhydric phenols (e.g. diphenylolpropane) and epichlorhydrin.

Patent DE-2142766-A1 (DE)
Title: Rotary cement kiln - with helical lifting channels for preheat zone
Inventor: JENSEN FLEMMING EDVIN
IPC: F27B7/16
Filed: 1971-08-26
Abstract: The preheating zone of a rotary inclined cement kiln is provided with helical lifting channels from which particles cascade to establish a series of curtains extending at an acute angle, such as 15 degrees to 25 degrees, to the kiln axis. The hot gases become supersaturated with particles in passing through each curtain, and the particles in the gas stream are either carried through succeeding curtains or deposited but the stream remains supersaturated. Any particles in the gas stream emerging from the kiln are recovered and fed back to the kiln. The recirculation in the preheating zone allows the use of shorter kilns.

Title: Rolling mill with oscillating rollers - has reciprocating feeder which operates in synch. with roll nip changes
Inventor: WIEDEMER KARL GUSTAV DR ING
IPC: B21B13/18
Filed: 1973-05-29
Abstract: The material to be rolled is unwound from a coil by gripping heads on a reciprocating feeder operated on parallel linkages by a crank mechanism. The motion of the feeder is synchronized with the vertical displacement of a reduction roll set controlled by a hydraulic cylinder with an accumulator which ensures a constant roll pressure on the handle material. A roller turning the material through 90 deg. swings in synch with the reduction roll set and feeder while a tension roller ensures a constant tension of the rolled material. Spacers between the rolls of the reduction set maintain a predetermined thickness of the rolled material.
Patent DE-2333134-A1 (DE)
Title: Battery charging monitoring to specified characteristics - uses comparison with three reference charging phases and excess switch-off
Inventor: FRANKE HERMANN
IPC: H02J7/00
Filed: 1973-06-29
Abstract: The monitoring of battery charging is based on the critical characteristics of the three charging phases. The initial charging current is continuously monitored by a current sensitive circuit with mains switch-off when the limit is exceeded. The second charging phase is monitored by a switch, sensitive to the limit value, which in case of excess voltage cuts off the mains, or after a defined time switches over to charge current measuring, and a limit switch responding to current excess. The current sensitive switch can be a fuse, and the second phase monitoring can be via a voltage divider at the charger output, connected to the limit switch input. The current measuring may use a D.C. converter connected to the limit switch.

Title: Ventilated shoe cupboard and built-in extensible shoe cleaning machine - sets up electrostatic charges to prevent dust from settling
Inventor: HEZINGER GEB UHLEMANN ELSE
IPC: A47L23/02
Filed: 1973-08-11
Abstract: The shoe cupboard contains several shelves with air valves which allows air circulation thus improving the condition of the shoes. The shoe cleaning machine which may be of steel, cast iron, plastics or other suitable material is stored at the bottom of the cupboard and is designed to be extended for cleaning the shoes. When using the machine, the casing is designed so that the two brushes housed therein set up an electrostatic charge which picks up the dust and prevents it from contaminating the cupboard. Beneath the cleaning and polishing brushes is a dirt collecting tray which is designed to be detachably held by its own force inside the machine. An electrostatic charge is also set up in this tray to ensure no dirt can escape. A dispenser for a colourless shoe cream is located on one side of the machine and is designed to spray the cream onto the shoe by actuating a ball valve.

(I) reduced the oxygen requirement of heart muscle and increase tolerance to anoxia; they are therefore useful in the treatment of e.g. coronary insufficiency. Since the nitrate ester function is relatively stable towards acidic and alkaline hydrolysis but can readily be displaced by other nucleophilic reagents, (I) are also useful as intermediates in pyrimidine and purine nucleoside chemistry.

Title: Non-mechanical printing process using toner powder - has laser beam used to fuse powder to thermoplastic coated paper
Inventor: HEINZL JOACHIM L DR ING
IPC: B41J2/44
Filed: 1973-09-27
Abstract: The paper web is extracted from a supply roll by two rollers and passes under a hopper containing toner powder which is fed in the required quantity onto the paper by means of metering rollers in the hopper. The paper web covered with powder passes between electrodes which apply a limited charge to distribute the powder evenly. The paper is then heated by a lower heating roller so that the laser positioned above the web does not have to supply all the heat necessary to fuse the powder. The paper web then turns down around a guide roller which serves to cool the paper. Unfused powder either falls off the web or is removed by a brush or electrodes, and is collected in a receiving vessel. A gas e.g. CO2 laser is used in conjunction with optical light guides.

Title: Continuous accumulator rapid charging cct. - repeats charging process in cycles even with fully charged accumulator
Inventor: STILLER ARMIN
IPC: H02J7/00
Filed: 1973-12-22
Abstract: The rapid charging circuit for accumulators has the accumulator coupled over a thyristor switch to the output of the rectifier. The thyristor gate is coupled to a thyristor discriminator that turns off the main thyristor, when the accumulator terminal voltage reaches a given level. A pulse generator is connected to the discriminator and to the main thyristor gate such that, when the main thyristors is off, the discriminator is repeatedly blocked to turn the main thyristor on again and to restart the charging process. Even if the accumulator remains fully charged these recharging cycles continue. The discriminator thyristor gate may be coupled to a voltage divider across the accumulator.

Title: Sewage sludge drying system - using heating elements in tank and moving carriage with bars to breakup drying sludge
Inventor: SKOWRONEK HEINRICH
IPC: C02F11/13
Filed: 1974-02-09
Abstract: Sewage sludge is dried out by removing the moisture through evaporation by heating elements arranged below the level of the sludge and by simultaneously extracting the water vapour above the surface. A hot air stream can also be directed across the surface. At the same time, the drying sludge is mechanically broken up by vertical rods, pref. of square section with one corner leading, which are pulled in one or several directions through the sludge. Process avoids use of drying beds which require a long time and contaminate the ground water supply, and can be adjusted to achieve any desired degree of drying.
