Title: Barrel for rock breaking tool
Inventor: VAN DER WESTHUIZEN HERMANUS Q
IPC: F42D5/05
Filed: 1987-06-11
Granted: 1991-11-12
Abstract: A B S T R A C T     A method of breaking up rock including drilling a hole in the rock,  substantially filling the hole with water,  and inserting a barrel of a rock breaking tool into the hole, the tool  being  operable  to discharge  a  cartridge  from a  firing chamber down the barrel, and discharging the cartridge down the barrel to cause an impulsive energy shock in the water to break up the rock.   The barrel used is short so as to be inserted in the entrance portion only of the hole, and a blast absorbing mat is located over the tool to retain it substantially in position in the hole during discharge of the cartridge.

Abstract: PROCESS FOR EN ROUTE AIRCRAFT CONFLICT   ALERT DETERMINATION AND PREDICTION                ABSTRACT OF THE DISCLOSURE       A process is provided for establishing when selected pairs of airborne aircraft are in en route conflict or are in potential en route conflict.  The process includes a number of "filtering" steps arranged in three branches. At each step, different conditions, such as height separation, lateral separation, height convergence, lateral convergence and "look-ahead" projections are examined for each aircraft pair.  Criteria are established for each "filtering" step such that aircraft pairs not passing the filter to the next step are exited as either "no conflict", "current conflict" as "potential conflict".  Sixteen such filtering steps are provided, one of which establishes a "current conflict" status and four of which establish a "potential conflict" status.

Abstract: A filter-device and a filter-appliance from such filter devices.                              A B S T R A C T. A description is given of a filter-device for filtering  particles from a gaseous medium,  the  said  device  comprising a substrate (22) and a filter-bed provided thereon.  The filter-bed is a filter-fluid (36) which wets the said substrate. At least one such filter-device (20) is arranged to form a filter-appliance (10) in a housing (12).  The said housing has an inlet-aperture (14) and an outlet-aperture (16) for the medium to be filtered.  In order to ensure that the gas-permeable substrate (22) in the at least one filter-device (20) of the filter-appliance (10) is adequately wetted by the filter-fluid (36), the housing (12) contains a spraying device (44) having a fluid connection with the filter-devices (20), the said spray-device having a fluid connection with a collecting chamber (38) for the said filter-fluid.  For the purpose of circulating the filter-fluid between the collecting chamber and the spraying device, use is made of a pump (47).     (Fig. 1).

Title: Method and apparatus for driving neon tube to form luminous bubbles and controlling the movement thereof

Granted: 1993-06-22
Abstract: METHOD AND APPARATUS FOR DRIVING NEON TUBE TO FORM LUMINOUS BUBBLES AND CONTROLLING THE MOVEMENT THEREOF     Abstract of the Disclosure According to the present invention, a portion of an applied commercial AC supply (60 Hz) is rectified, filtered and a controllable oscillator in a pulse width modulator chip serves as a signal generator which has both duty cycle and frequency control adjustments.  An output signal is coupled via an impedance matching circuit to the input primery winding of a signal transformer having a pair of secondary windings which drive a pair of tandem connected electronic switches which, in turn, are connected across a second DC supply which has a high direct current voltage derived from the input AC line voltage (110-120V AC 60Hz).  A pair of tandem connected capacitors is connected across the DC supply and an intermediate point between the tandem connected electronic switches is connected to one end of the primary winding of a high voltage output transformer and a second intermediate point between the two tandem connected capacitors is connected to the opposite end of the primary winding of the high voltage output transformer so that on alternate half-cycles of the input signal coupled to the signal transformer from the impedance matching transistor switches is used to alternately drive the gate electrode of the electric switches.  A series of control sequences for the switches is stored in a memory, and a microprocessor is programmed to selectively retrieve one or more control sequences so as to cause the luminous bubbles in one or more neon tubes to go through a predetermined program of movements.  A ground-fault sensing shut-off circuit is connected to one of the output terminals of the high voltage output transformer and includes comparator circuitry which is capable of sensing when a person, for example, touches one of the output terminals of the high voltage output electrode  and disable the electronic switches.

Title: Relational database system
Inventor: HUBER VAL J
IPC: G06F12/16
Filed: 1988-01-07
Granted: 1991-10-15
Abstract: ABSTRACT            Apparatus used in a relational data base system to maintain a dependence between a user-defined field in a row of one base table and the state of a set of rows in another base table.  There are three kinds of dependent fields: a count field which contains a count of the rows in the set, a sum field which is the sum of a field in the rows of the set, and a base copy down field, which is a field in the rows of the set which contains a copy of a value in a field in the row of the one base table.  The two base tables make up a referenced-referencing pair and the row from the one table has a primary key which is used as a foreign key in the set of rows of the other base table.  The apparatus consists of components in the data dictionary which define the user-defined dependent field and the nature of the dependence, including any conditions thereon, and components in the data base system's run time system for maintaining the dependence.  Each time the state of a row in the referencing base table is altered, the run time system uses the data dictionary to determine whether there is a user-defined dependent field, and if there is, what kind of dependent field it is.  Code in the run time system then reestablishes the dependence as required for the altered row.

Abstract: ABSTRACT OF THE DISCLOSURE           A device is disclosed for continuous hot-sealing of thermoplastic films.   This device comprises a sealing head provided with two rip cord electric resistances that are heated by causing an electric current to flow therethrough. The resistances are made of a material the electric resistance of which is proportional to the temperature.  The sealing head is caused to rapidly vibrate against a counter-plate so as to cause the thermoplastic film to be sealed to be rapidly pounded as it glides between the head and the counter plate. The sealing of the thermoplastic film is brought about by the synergistic action of the heat of the resistances and the pressure due to the pounding.

Granted: 1993-07-20
Abstract: STRAIGHT CONNECTING HYDRAULIC QUICK COUPLER     ABSTRACT OF THE DISCLOSURE     A quick connect/disconnect hydraulic coupler is provided especially for connecting rigid hydraulic members where no axial movement of the coupling halves can be achieved.  The quick coupler comprises a male connector attached to one hydraulic line and a female connector attached to another hydraulic line.  The male and female connectors each include an annular check valve that is spring-biased against a poppet seat to prevent loss of hydraulic fluid when the coupler halves are disconnected.  The male connector has an annular coupling nut surrounding and confining the male check valve.  When the male and female connector halves are aligned, the coupling nut can be moved axially toward the female connector and rotated to engage threads on the outside circumference of the female connector. Tightening the coupling nut onto the female connector forces the male check valve to extend and to form a seal with the female check valve.  Tightening the coupling nut also forces both the male and female check valves off their poppet seats to open hydraulic ports and establish fluid flow through the coupler.
