Title: Stable analogs of bioactive peptides containing disulfide linkages
Inventor: SRINIVASAN ANANTHACHARI
IPC: C07K7/16
Filed: 1995-07-18
Abstract: Stable analogs of cyclic peptides containing disulfide linkages are disclosed.  The disulfide linkage is modified by one of four methods: (a) sulfide contraction, (b) isosteric substitution, (c) thioketal expansion, or (d) alkylation expansion. In sulfide contraction the disulfide bond (-S-S-) is replaced with a monosulfide bond (-S-) in which a bifunctional effector molecule, such as a ligand or chemotoxic agent, is bound to the new peptide linkage. In isosteric substitution, one sulfur atom is replaced with a carbon atom and at least one of the carbon atoms at the modified side is a bifuctional effector molecule. In thioketal expansion, an alkylidene unit (-CR1R2-) is inserted between the two sulfur atoms. In alkylation expansion, an alkyl moiety of from C2 to C3, is inserted between the two sulfur atoms.

Title: Method and Apparatus for Applying Multiple Speech Processing Features to a Telephone Call
Inventor: BEGEJA LEE
IPC: H04M3/00
Filed: 1997-03-06
Abstract: A speech processor uses a plurality of speech processing features to enhance the quality of speech signals received by a user during a telephone call.  The activation of a second speech processing feature is delayed for a time duration measured after the initiation of a particular call or measured after the activation of a first speech processing feature.  This delay eliminates any interference between the second speech processing feature and the first speech processing feature that is active when the call is initiated.  The delay also increases the time it takes for the speech processing features to become fully effective, thus making the enhancement in the quality of the speech signals more noticeable to the user. Further, an optionally generated audio indicator is provided when the second speech processing feature is applied so that the additional feature is even more noticeable to the user.

Abstract: With reference to the figures, a cream depositing machine (1) comprises a rotatable stencil drum (2) having a series of first and second stencil ports (3, 4) disposed in four groups angularly around the circumference of the drum (2), at substantially 90~ spacings. Each group comprises a single port (3) surrounded by an outer port (4) of annular form, the ports (3, 4) being disposed in close proximity. A chain drive sprocket (5) mounted on the stencil drum (2) comprises means for causing the drum to rotate in timed sequence about its longitudinal axis (6) as indicated by arrow (11). Source means (12 and 13) are provided for the pumped supply of first (8) and second (9) cream material separately to each group of stencil ports (3, 4). Cream flow control means (10) within the stencil drum (2), are operable, in timed sequence, (caused by drum rotation), to initially cause first cream material (8) to issue from the central stencil port (3), and thereafter, after angular movement of 90~ of the stencil drum (2) to cause second cream material (9) to issue from the second or outer stencil port (4) surrounding the central port (3), whereby separate deposits of first and second cream material (8, 9) coexist on the stencil drum 2. A stationary cutting wire (15), in light contact with the stencil drum (2), is provided for simultaneously removing the coexisting deposits of cream. Figures 6 to 14 show a dual drum machine provided with cream supplies (12, 13) for one drum (2), and further cream supplies (121, 131) for the other drum (7). For recirculation of cream the supply (12) can be connected to supply (121), and supply (13) to supply (131).

Patent CA-2209055-A1 (CA)
Title: Peripheral interface card
Inventor: LACAVA LEONARDO
IPC: G06F13/40
Filed: 1997-07-28
Abstract: A dual port computer interface card for controlling a number of peripheral devices such as video game controllers with 23 separate analog inputs and outputs.  This card uses a single 16 Bit ISA (International Standard Architecture) connector on a PC (Personal Computer) bus for all input and output functions. An address decoder enables the on board functions of the card when polled by a computer software program. Once enabled, the computer program can need or write data to or from the card. The stored data in the card's memory is the converted analog input obtained from peripheral devices connected to the input port. When a read request is made by the software, this data will be output to the PC data bus and the card returns to a monitoring state. When a write request is made by the software, the card will read the data from the PC bus and store it into a specified memory address. This digital data will be converted to an analog signal and output to one of the pins of the output port. A peripheral device connected to this output port and equipped to receive this signal will produce the appropriate function or action.

With rhodium and iridium the immobilised ferrocenyldiphosphine ligands form complexes that can be used as highly active catalysts in the enantioselective hydrogenation of carbon-carbon, carbon-nitrogen or carbon-oxygen double bonds.
