Title: "leg-operated garden tools"
Inventor: SASU IOAN
IPC: A01B1/00
Filed: 1993-10-14
Abstract: LEG-OPERATED GARDEN TOOLS       ABSTRACT Leg-operated garden tools comprise of various interchangeable tools attached essentially to the heel of a person' shoe. There are two distinct categories: 1.Tools operated just in the vertical direction, which use the user's weight to do the job. Simply walking across the ground to be cultivated, causes the tools to penetrate into the soil, carrying out different kinds of cultivation practices such as: coring, slicing, spiking and cutting of the turf, creation of bulb-sized planting holes or transplant holes, compression of the soil, etc. The user's weight may activate also some tools mechanisms e.g. that of hinged shears. 2. Tools operated in the horizontal and vertical direction. The user presses down and at the same time draws the tool either backward or forward. For soil cultivation there are: gap cleaner, all purpose rake, single plow, double plow, cultivator, shallow furrows maker and hoe. There is the possibility to use wheels to activate some tooling mechanisms e.g. rotary shears, or reciprocating shears. All these tools are interchangeable being attached to the tool attachment by a clamping system and to the heel of the shoe by various kinds of attachments which may use a clamping and safety device. The person may wear a conventional shoe or a shoe having secured inside the heel a clamped element of a clamping and safety device. The same tool can be used for different shoe sizes due to the adjustable attachment. In order to achieve the desired practice, various tools can be mounted on the same attachments and the same shoe. For the first category, some tools may be designed also for a heavy animal to be attached to its hoof.

Title: Current cell and switch for digital-to-analog converters
Inventor: LEUNG BOSCO
IPC: H03K17/041
Filed: 1993-12-21
Abstract: An improved current cell and current switch is described for use in digital-to-analog converters and other current mode circuits.  The current switch is implemented using BiCMOS circuitry which is characterized by an absence of base current error and a switching speed which is approximately twice as fast as the switching speed of prior art MOS-based switches.  According to one embodiment, the current cell is implemented in BiCMOS which offers higher output resistance, smaller minimum voltage, and improved accuracy over prior art MOS-based self-calibrated current cells.  According to another embodiment, the current cell is implemented in CMOS and is characterized by a significant reduction in charge injection, leakage current and error due to coupling of the cell output voltage back to the storage node, as compared with prior art MOS-based current cells. Furthermore, a current-steering digital-to-analog converter is described which incorporates the improved current cell and current switch of the present invention.

Title: Latch guard for inwardly opening doors
Inventor: ALLENBAUGH HOWARD M
IPC: E05B17/20
Filed: 1994-04-27
Abstract: LATCH GUARD FOR INWARDLY OPENING DOORS                 ABSTRACT OF THE DISCLOSURE            An interlocking latch guard for obstructing and resisting the unauthorized opening of an inwardly opening locked door comprises a frame channel mountable on the outside surface of a door  frame,  and a door channel mountable on the outside surface of a door.   The frame channel has a pair of spaced apart, parallel side flanges, and a front flange directed perpendicularly to the side flanges such that the frame channel has a generally U-shaped cross-section.  The door channel includes at least one  interlocking  flange,  and  a  back  flange  directed perpendicularly to the interlocking flange.  When the door is closed and locked, and the channels are appropriately mounted by fasteners, the interlocking flange of the door channel protrudes substantially parallel to and in between the side flanges of the frame channel, thereby restricting or  blocking  access  to  the  fasteners.     In  this configuration, the interlocking latch guard protects the latch from being tampered with by the use of tools, such as jimmy bars, flexible strips, or devices used to spread the door frame to disengage the latch from the frame.

Title: Catalyst composition for the selective hydrogenation of benzene and process for such hydrogenation
Inventor: GILL UDAI S
IPC: B01J31/24
Filed: 1994-08-02
Abstract: Abstract of the Disclosure A novel catalyst has been provided for the selective hydrogenation of benzene in gasoline.  The catalyst mixture comprises  a  water-soluble,  organo-metallic,  selective benzene hydrogenation catalyst comprising catalytically-active mixture of (A) M[L]x[X]y wherein M is Cr, Fe, Co, Ni, Mo, Ru, Rh, Pd, Ta, W, Re, Os, Ir, Pt, La or Ce; L is an aromatic hydrocarbon, e.g., benzene, diphenyl, etc., or a diaromatic hydrocarbon, e.g., naphthalene; X is a halogen; x is an integer from 1 to 10 inclusive; and y is an integer from 1 to 10 inclusive; and (B) tris(triphenylphosphine)-rhodium(I)halide   or   tris(triphenylphosphine)ruthenium-(I)halide.   In use,  the process comprises admixing the gasoline with water.  The above-identified water-soluble, organo-metallic selective benzene hydrogenation catalyst mixture is then added.  A catalytic hydrogenation is then carried out in a hydrogenation zone at a temperature of 150° to 245°C at a pressure of up to 1000 psi in a biphasic system of the water and the gasoline.   The benzene is selectively solubilized in the water and thus is selec-tively hydrogenated in the presence of the above-identified water-soluble  organo-metallic  catalyst  mixture.    The gasoline is then recovered from the hydrogenation zone.     This combination of both catalysts was found to produce conversions in excess of 40% which was much greater than either of the catalysts separately and at the lowest effec-tive temperature of 150°C.
