Title: Battery jumper cable
Inventor: MERIO RAOUL
IPC: H02H9/04
Filed: 1987-09-01
Granted: 1992-03-03
Abstract: ABSTRACT    A battery jumper cable comprises a first electrically insu-lated flexible low-voltage conductor having two end portions each electrically connected to an insulated pair of pole pliers and a second electrically insulated flexible low-voltage conductor hav-ing two end portions each electrically connected to an insulated pair of pole pliers.  To prevent the occurence of high peak vol-tages which may affect vehicle electronics during a jumper oper-ation temporarily transmitting electrical power for starting a first vehicle with a discharged storage battery from a storage battery of a second vehicle, there is provided an  electical con-nection between the first low-voltage conductor and the second low-voltage conductor.  This electrical connection has a voltage-dependent resistor exhibiting a forward voltage in excess of the operating voltage of conventional starting batteries for auto-motive vehicles.  The voltage-dependent resistor may be accommo-dated within a housing.

Title: Method and apparatus for making a slurry trench or wall in the soil
Inventor: VERSTRAETEN ALEXANDER J
IPC: E02D7/18
Filed: 1987-12-30
Granted: 1991-12-03
Abstract: Abstract of the disclosure A method and apparatus for making a slurry trench or wall in the soil, comprising driving a beam section into the ground by pile driving, and simultaneously and entirely filling up the trench formed by soil displacement with a supporting fluid. The beam sectional is subsequently pulled out of the soil with a vibrating movement, which is obtained by delivering blows to the beam at a suitable frequency. During this extraction movement,sufficient supporting fluid is supplied for filling up the volume occupied by the beam. The soil displacement portion at the  under-side  of the beam, in cross section, has a box section with apertured side walls. The box section is shut off at the under-side by a permanent pile shoe or by hinged flaps, so that during extraction of the beam out of the soil, the interior of the box section communicates with the trench formed underneath the flaps or the pile shoe, said trench being thereby filled with supporting fluid.

Title: Process for the oxidation of fine coal
Inventor: CRONJE IZAK J
IPC: C08H99/00
Filed: 1988-07-07
Granted: 1994-06-07
Abstract: A B S T R A C T This invention relates to the production of a solid oxidised coal containing humic acids.  Coal with a mean particle size of less than 3mm is slurried with water and then oxidised with oxygen or mixtures of oxygen and air at temperatures ranging from 100 to 300°C, at partial oxygen pressures ranging from 0,1 to 10 MPa and reaction periods ranging from 5 to 600 minutes.  In the absence of catalysts, e.g. alkaline bases, the main product of oxidation is humic acids. These humic acids are not dissolved because the pH of this slurry is in the range 4 to 9.  Small amounts of fulvic acids are formed and these are soluble in the water of the slurry.            The coal-derived humic acids may for example find application as soil conditioners, organic fertilisers, briquette and pellet binders, drilling fluid dispersants and viscosity control agents, whilst the coal-derived fulvic acids may be utilised for the production of fuel extenders, plasticisers and petrochemicals.

Abstract: ABSTRACT OF THE DISCLOSURE A vehicle-mounted telephone or similar small-sized equipment having a handset with a liquid crystal display (LCD) and a cradle for holding the handset in place. Sensor is built in at least one of the handset and cradle to determine whether or not the handset is present on the cradle. In response to a sense output of the sensor, a controller varies drive voltage which is applied to an LCD driver and thereby varies the visual angle of the LCD automatically. The drive voltage selectively has a first value associated with a first visual angle which occurs when the handset is mounted on the cradle and a second value associated with a second visual angle which occurs when the handset is removed from the cradle. The controller further controls the drive voltage in such a manner as to selectively apply drive voltage associated with any of a desired number of visual angles to the LCD driver. An implementation is provided for allowing a person to manually change the drive voltage in a stepless or analog fashion as desired.
