Patent WO-8002482-A1 (WO)
Inventor: BAILEY R
IPC: H02P3/08
Filed: 1980-04-24
Abstract: A propulsion system for an electrically driven traction vehicle includes a chopper (12), a d-c traction motor (11), and means (103, 132, M) effective when the system is operating in a motoring mode for connecting the chopper in series with the armature (80) and the field windings (81) of the motor to a d-c electric power source (35, 38, 33, 32) that includes a filter capacitor (60). Cyclically operative means (193) provides periodic gating signals for alternately turning on and turning off the chopper, and it can be smoothly changed from a constant frequency, variable pulse width mode to a variable frequency, constant (minimum) off time mode so as to vary the "duty factor" of the chopper over a wide range extending up to 100 percent on time. Brake set up means (103, 132, B, 152, RR) is operative in response to a motoring-to-braking command for reconnecting the chopper in parallel with the motor and the filter capacitor and for reversing the polarity of the connection of the series field winding relative to the armature. In response to this operation of the brake set up means, current in the field of the motor is momentarily boosted (83, 84, 86, FS, 184) and an extended chopper turn on signal (191) having a duration substantially longer than that of the aforesaid periodic gating signals is supplied to the chopper to ensure that it turns on and conducts armature current to begin the braking mode of operation even if the command happens to take place at low speeds when the electromotive force of the motor is correspondingly low.

Title: Buffer circuit for semiconductor memory
Inventor: PLACHNO ROBERT S
IPC: H03K19/0185
Filed: 1980-11-07
Abstract: A buffer circuit (10) receives an enable signal to drive power transfer transistors (12, 14) which supply power to circuit elements in a semiconductor memory. When an enable signal is driven to a high state the gate terminals of the power transfer transistors (12, 14) will be driven positive thereby rendering the transistors conductive. When the enable signals transitions to a low voltage state first and second clock signals (oC1 and oC2) are generated. The action of the clock signal serves to pull a node (20) to one voltage threshold below the reference V<uss>u. A second node (64) is driven to two thresholds below the reference of V<uss>u. The second node (64) connected to the gate terminal of the power transfer transistors (12, 14) to affirmatively hold the power transfer transistors (12, 14) in a non-conductive state to essentially block the transfer of any current through these transistors to the circuit elements of the semiconductor memory thereby eliminating any power loss due to current leakage through the power transfer transistors (12, 14).

Title: Cell-seeding into fibrous lattices by means of centrifugation
Inventor: YANNAS IOANNIS V
IPC: A61L27/60
Filed: 1982-10-26
Abstract: This invention comprises the use of centrifugal force to introduce viable cells into a fibrous lattice, as well as fibrous lattices that are seeded with cells by the use of centrifugal force. A variety of fibrous lattices may be seeded by the methods of this invention, such as a highly porous lattice comprising collagen fibers crosslinked with glycosaminoglycan. Before the centrifugation, a piece of intact tissue is harvested from a donor site. It is treated with one or more substances, such as trypsin or collagenase, to dissociate cells from the tissue. The cells are then mixed with an aqueous solution to create an aqueous suspension of cells. A piece of fibrous lattice is placed within a container, referred to herein as a "bucket", that is suitable for rotation by a centrifuge. The aqueous suspension of cells is placed within the bucket, in contact with the lattice. The centrifuge is then rotated. Centrifugal force causes the cells, which are denser than the aqueous solution, to be forced into the lattice in a relatively uniform distribution. By controlling various parameters, cells can be seeded into any desired location within a lattice

Title: Control of dna sequence transcription
Inventor: PALMITER RICHARD D
IPC: C12N15/62
Filed: 1982-11-23
Abstract: The transcription of DNA sequences in living cells is subjected to external regulation by incorporation of promoter/regulator DNA sequences responsive to metals and/or steroids. More particularly, regulation of the transcription of selected exogenous DNA sequences incorporated into eukaryotic host cells is facilitated by operative association (e.g., fusion) of the selected sequence to a promoter/regulator DNA sequence which is positively or negatively responsive to environmental variation in the concentration of heavy metal ions and/or steroid hormones. As an example, a structural gene for thymidine kinase from herpes simplex virus, fused to the promoter/regulator DNA sequence of a mouse metallothionein-I gene and incorporated on a suitable DNA plasmid vector, is introduced into mouse embryos and stably incorporated therein. Gene expression in differentiated cells of adult mice resulting from the embryos is subsequently regulatable by administration of heavy metals such as cadmium or steroid hormones such as the glucocorticoid, dexamethasone.

Title: Demultiplexer circuit
Inventor: HUBBARD WILLIAM MARSHALL
IPC: H04M3/56
Filed: 1983-07-08
Abstract: A demultiplexer circuit which extracts from an incoming time division multiplexed digital bit stream any combination of pulse-code modulated (PCM) encoded words or data bits, irrespective of their rate or the position of the data bits in a given channel or channels. The demultiplexer circuit includes a random access memory (RAM 12) for storing address information as to the bit or bits to be demultiplexed out of the incoming digital bit stream (lead 15). A counter (13) operates in synchronism with the received bit stream and the output thereof serves to access the RAM to provide output signals indicative of the bit(s) carrying information for the subscriber station. These output signals are utilized to read the digital signals intended for said station into other RAMs (31, 41). A summing circuit (16-19) is coupled to the input of said other memory so that conference calls are summed in real time. The digital signals are then read out of the other memory at a steady rate, with a stored data signal being similarly outputted irrespective of the rate of the signal or its position in a given channel or channels.
