Title: Road-surfacing compn contg unvulcanised rubber or
Inventor: PETER DEFREGGER HANS
IPC: E01C13/06
Filed: 1968-10-01
Abstract: Road-surfacing composition consists of a mixt. of (I) gravel, (II) sand, (III) bituminous binders, and (IV) a multicomponent filler which increases the viscosity of the mastic formed from the filler and the bituminous binder. The wt. proportions of (I), (II) and (III) in the compn. are about the same as those in pouring asphalt or asphalt cement, while the wt. proportion of (IV) is reduced to a low value. The compn. pref. contains 10-15% wt. (IV). The component of (IV) increasing the viscosity of the mastic is pref. a clay treated with an organic wetting agent, or asbestos fibres, glass fibres, or mineral fibres, or of a long chain polymer, pref. unvulcanised rubber or a plastic material. The composition gives road-surfaces which are as tough and impact resistant as asphalt road surfaces, and as hard and economical as concrete road-surfaces.

Title: Motor vehicle collision prevention device - automatically activated air cushions carried inside or outside
Inventor: POHLMAN REIMAR PROF DR PHIL
IPC: B60R19/20
Filed: 1973-06-16
Abstract: By the fitting of air pressure inflating cushion bags to the outside or inside of vehicles the effect of direct collisions could be considerably reduced. This proposal covers the application of ultra sonic sensing devices (20-30kHz range) to identify impact situations and to activate the appropriate pressurisation at the correct time. The inflation would vary but could be effective for a period of 2 milli-seconds externally. The construction of the concertina-form cushions would depend on the grade of application expected, so the material suppleness and excess pressure valves would be set accordingly.

Title: Tea-bag collective packing system - wheel with cam controlled jaw pockets collects, clamps and discharges package
Inventor: NAYLOR JAMES
IPC: B65G47/86
Filed: 1973-07-10
Abstract: The sachets, e.g. tea bags, are collected and boxed in flat stacked state by means of a rotating collector wheel which receives set amounts of bags at one point and issues a collected pack at another station. The filled tea bags typically are fed in steady flow and singled out by a cutting operation ahead of the wheel, so as to enter the cam controlled jaws of the wheel pockets in a timed sequence which is adapted to the wheel speed in such a way that each pair of jaws grasps a preset number of bags to form a collected pack at the pickup point. The jaws are then pressed against the bags and not opened until they reach the station where the collected pack of bags is discharged.
Patent DE-2340817-A1 (DE)
Title: Gripper loom selvedge development unit - has wheel to turn ends of wefts to be secured by spot adhesion or welding
Inventor: SCHNEIDER AXEL
IPC: D03D47/50
Filed: 1973-08-11
Abstract: The process to bind the edges of a fabric developed on a gripper loom uses a wheel to turn the ends of the wefts, followed by a turning of the edge for spot welding or adhesion. The system secures the selvedge, whether the wefts are of natural or synthetic fibres, with economic use of adhesive or welding energy. The pin wheel turns the ends of the wefts under the fabric and the edge is further turned. In the case of an adhesive, the adhesive is fed to an applicator operated by a Bowden (RTM) cable against a return spring by the loom, to give spot applications, followed by drying. Similarly, heat can be applied in an intermittent action to give a spot welding effect to secure the turned-under edge of the fabric.

Title: Clip-on selective connector for current rails - has end flap with removable contact blades passing down into insulated rails
Inventor: PEPPING FRANZ
IPC: H01R25/14
Filed: 1973-09-18
Abstract: The clip-on selective connector for three-phase current rails, consists of an insulating rectangular block which clips into a channel in the assembly supporting the parallel current rails. The rails are embedded in an insulator at the bottom of the channel and accessible through narrow slots along their lengths. The contact end of the block has a hinged flap which pivots up to expose the blade contacts inside it. These blade contacts can be inserted into the flap at will and therefore connections to one or more rails can be made as required. Pushing the flap down presses the blade contacts down through the slots onto the rails. The connector output is taken from a screw connection on its top surface.

Title: Germinated grains treatment for bread dough admixt. - by brief heating to kill starch-destroying enzymes
Inventor: BERNASEK JIRI DR
IPC: A21D2/38
Filed: 1973-10-18
Abstract: In a process for the treatment of germinated cereal grains, in the mfr. of breah and pastry, the grains are briefly (20 mins. to 6 (hours) heated to 70-90 degrees C (85 degrees C) after the germination and before the dough is prepd. This makes germinated grains usable for human consumption and reduces the baking time from 24 hours for the Horlebeck method to 85 mins. It is not confined to the baking of pumpernickel and utilises the vitamins contained in germinated grains.

Title: Parameters of network adjusting device - signal is alternately applied at high switching speed to network input and output
Inventor: TOKOYO NOBORU DIPL ING
IPC: G01R27/30
Filed: 1974-01-16
Abstract: A circuit has a number of outputs at which signals appear as a result of alternate high speed switching, which are proportional to the power reflected from the network input to that passed through the network, and to that reflected from its output. Further circuits are connected to these outputs which allocate to the above signals adjustable weighting coefficients. These signals are then added, and their sum displayed. The signal is generated by a wobbling generator. The signal proportional to the power passed by the network, together with a further signal proportional to the power delivered by the wobbling generator, are applied to the inputs of a differential amplifier. Their difference, after weighting, is used for the sum signal formation.
