Title: Method of making color picture tube shadow mask having improved mask aperture border
Inventor: MARKS BRUCE G
IPC: H01J31/20
Filed: 1991-06-13
Abstract: An improved color picture tube has a shadow mask having an aperture array including slit-shaped apertures aligned in columns that essentially parallel the minor axis and end at a border of the array. Adjacent apertures in each column are separated by tie bars in the mask. The tie bars in one column are offset in the longitudinal direction, paralleling the minor axis, from the tie bars in each adjacent column. The spacing between tie bars in a column is the tie bar pitch at a location on the mask. A first set of columns, comprising every other column, has increased tie bar pitch at the ultimate end apertures, as compared to the tie bar pitch at the penultimate apertures in each of the columns. In a second set of columns, every other column not in the first set has decreased tie bar pitch at the ultimate end apertures, as compared to the tie bar pitch at the penultimate apertures in each of the columns. The last tie bars before the ends of the aperture columns in the second set are shorter than the next to the last tie bars, measured in the longitudinal direction of the columns, and the ultimate apertures at the ends of all of the aperture columns end on a smooth border line.

Abstract: ABSTRACT OF THE DISCLOSURE    A system for remotely programming a mine includes a programming device comprising a computer having a data memory storing data representing all functions required to control the mine once the mine is laid, a code word memory and a random number generator.  An output device is connected to the computer for displaying the data contained in the data memory.  An input device causes data stored in data memory to be displayed by the output device, requests the random number generator to generate random numbers corresponding to respective addresses in data memory under which selected functions displayed by the output device are stored, and causes the storage of the generated random numbers as code words, together with corresponding data memory addresses, in the code word memory.  A transmitter is connected to the computer for providing contactless transmission of the contents of the code word memory.  A programmable electronic unit in the mine includes a receiver tuned to the transmitter of the programming device and a second computer connected to the receiver.  The second computer has a second code word memory for storing the contents of the transmitted code word memory, and a second data memory corresponding to the data memory of the programming device storing data identical to the data stored in the data memory of the programming device.  The second computer correlates a subsequently received code word with a code word previously stored in the second code word memory so that the function in the second data memory stored under the address corresponding to the subsequently received code word can be carried out.

IPC: H03K17/66
Filed: 1990-04-18
Abstract: A controllable circuit (10) having protection against damaging switching conditions for its component transistors (12) is described. The circuit (10) is a full-wave inverter bridge being controlled by a pulse width modulation technique, to which is connected an inductive load (50) and a resonant circuit (30). The circuit (10) also comprises snubber circuit (18) and free-wheeling diodes (14) associated with each transistor (12). The transistors (12) are switched between on-states and off-states to synthesize a pulse width modulation waveform from input supplies Vs+ and Vs- at the output terminals VA and VB. The elements of the resonant circuit (30) provide for placing the transistors (12) in an advantageous condition for switching between states, such that they do not experience undue damage or stresses. The method of operation includes switching-on one of the controllable transistors (22) to provide an alternative path for the load current, IL, thereby forming a resonant circuit by two capacitors (20), the inductor LC and the load. In this way, there is control over the rate of rise of the off-state voltage, dv/dt, and the rate of rise of on-state current, di/dt, and minimization of the static off-state voltage all with respect to the transistors (12). The diodes (24) provide blocking in respective opposite half cycles.

Title: Polymeric carriers for release of covalently linked agents
Inventor: SRINIVASAN ANANTHACHARI
IPC: A61K47/48
Filed: 1992-09-01
Abstract: Abstract A chemically defined polymeric carrier comprising a series of .alpha.-amino acids in any combination containing side chains to which diagnostic/therapeutic  and chelating  agents  can be  covalently joined through cleavable linkers either directly or covalently joined through cleavable linkers after chemical modification of the side chains.  Hydrazone,  disulfide,  and ester linkages  in any combination can be present in the polymeric carrier between the side chains of the .alpha.-amino acids and the agents. The presence of a particular covalent linkage between the side chain and the agent in the carrier is determined by the functional group present in the side chain of the .alpha.-amino acid and the functional group present in the agent.  The .alpha.-amino acids with side chains to which agents do not covalently join can function as spacers to minimize interaction between bulky molecules attached to the polymeric carrier.  In addition,  those .alpha.-amino acids with charge or hydrophilic side chains to which agents do not covalently join can provide increased solubility to the polymeric carrier.
