Title: Method of handling aggregates and cement - involves use of sacks with integral water tight containers for transporting both materials together
Inventor: THIERSE DIETER
IPC: B65D88/16
Filed: 1990-10-13
Abstract: The method of handling building materials, basically aggregates and cement, requires sacks into which the material is filled for transportation to the place where they are required. They are then emptied into a mixer or spray machine. The aggregate is filled into the sack, and the cement is put into separate integral subsidiary containers which are waterproof to prevent the moisture from the aggregates mixing in with the cement. The sack and subsidiary containers are emptied separately but the materials come together in the mixer or spray machine. USE/ADVANTAGE - Saves energy and largely prevents emission of carbon dioxide.

Title: Plug for a plug and socket arrangement - has additional contacts to give wide range of electrical connections
Inventor: JAAG DIETER
IPC: H01R13/26
Filed: 1990-10-16
Abstract: The socket of a plug and socket connector has a row of contact springs (14) with freely moving blades (18) protruding into the space for the plug. Through spring force, the free blades (18) make contact against a pin (24). When the plug is inserted into the socket, it forces the blades (18) to lift off the pin (24) and to connect with a matching row of contacts on the plug. Withdrawal of the plug re-establishes the connection between the blades (18) and the pin (24). USE/ADVANTAGE - A wider range of electrical connections can be made than with a conventional plug and socket arrangement with the same number of contacts.

Title: Signal evaluation system for detecting line of sight - detects variation point between two signal levels using defined threshold level
Inventor: SHINDO OSAMU
IPC: H04N1/403
Filed: 1990-12-07
Abstract: The signal evaluation system for detecting the line of sight determines the variation point between 2 signal levels corresponding to the light reflected at the iris and the light reflected at the background of the eye. A threshold level between the 2 signal levels is fixed and 2 bit elements above or below this threshold level are determined, with a line defined by the output levels of this pair of bit elements, or a pair of bit elements with a defined relationship to the latter. A zero transition bit element is obtained from the intersection of this line with the zero level, used to define a second line with a lesser gradient. The variation point is determined from the intersection of the 2 lines. USE - For determining blinking direction of human eye using single-eye mirror reflex camera.

Title: Hydrogenation from carbonaceous waste products - uses counter flow reactor and direct mixing of waste and oil
Inventor: WUERFEL HELMUT DR ING
IPC: C10G47/00
Filed: 1991-04-20
Abstract: A process for hydrogenation of carbonaceous waste, partic. plastic materials uses between 5 and 60 wt.% pref. 30 wt.% of plastic waste in the hydrogenation mixt. and in combination with oil products. A high pressure, high temp., counter flow reactor is used whereby waste materials and the hydrogen are introduced into the upper and lower sections of the reactor respectively. Prod. vapour is taken from the head of the reactor, and residue drawn from the sump. Waste materials are combined with heated oil prods. in a mixing chamber, to a temp. of between 200 to 300 deg.C (pref. 250 deg.C) and injected into the reactor system. Gas and vapour withdrawn from the head of the reactor is passed through a condenser linked to a phase separator. A portion of the resulting oil fraction is fed back to the mixing chamber. ADVANTAGE - System building costs are lower because the need for a heat exchanger for the input materials is eliminated. Carbonaceous input material also does not need to be finely ground prior to hydrogenation.
