Title: Fluid dispenser
Inventor: BANKS STEWART
IPC: B65D35/28
Filed: 1991-07-22
Abstract: 90310-6/LEH/fs Abstract of the Disclosure A fluid dispenser for dispensing a fluid, such as soap, from a flexible dispenser compartment of a fluid dispenser pouch of the type having a discharge passage that extends along a tortuous path.  The dispenser has a dispenser mechanism in the dispenser station, comprising a backstop on one side of the dispenser path and a cam having a downwardly and rearwardly curved cam face confronting the backstop and located on the other side of the dispenser path.  The backstop cooperates with the cam to expel a measured amount of fluid from the dispenser compartment.  A cam actuating hollow pushbutton is provided, which pushbutton partially accommodates the cam within a front opening of the pushbutton.  Upper and lower guide slots are provided in each of two side faces of the pushbutton and receive and guide, upper and lower laterally extending pins on the cam.  A spring is provided within the pushbutton between a rear internal face thereof and a rear face of the cam.  The pushbutton is operable to effect relative movement between the cam face and the backstop.  This relative movement initially temporarily seals the dispenser compartment at its upper end and further pushbutton action causes the fluid trapped in the dispenser compartment to be expelled.

Title: Analog/digital voice storage cellular telephone
IPC: H04W88/06
Filed: 1990-04-13
Abstract: An analog-to-digital voice storage cellular telephone for recording voice messages while the user is away from the cellular telephone unit. In a preferred embodiment, the analog-to-digital voice storage cellular telephone comprises call answering circui-try (518) which is activated after a predetermined number of rings. Detection circuitry waits to detect a SAT signal during a preset period of time. Once the SAT signal is detected a prerecorded outgoing message is transmitted to the callers. The voice storage cellular telephone records incoming voice messages which are retrieved and replayed by users at their convenience. If the SAT signal is not detected, call terminating circuitry (518) immediately terminates call. In accordance with one aspect, voice messages may be recorded at the central cellular station in real time, subsequently transmitted to the voice storage cellular telephone at a high speed and reproduced at normal speed to reduce air transmission time and cost.
Patent CA-2052351-A1 (CA)
Title: Telephone handsfree algorithm
Inventor: REESOR GORDON
IPC: H04M9/10
Filed: 1991-09-27
Abstract: A handsfree telephone circuit has separate transmit and receive audio paths for connection to a microphone and speaker respectively. The circuit comprises a controllable attenuator in each of said transmit and receive paths, an attenuator control responsive to control signals to set the attenuation level of said attenuators, and a separate monitoring circuit connected to each of said transmit and receive paths for sensing audio signals therein. Each monitoring circuit comprises a filter for band limiting the audio signals, a peak level detector receiving said band limited signals, and a speech detector for distinguishing speech from background noise. A switching comparator compares the outputs of the peak level detectors in the two monitoring circuits and produces directional control signals for said attenuator control means to determine which audio path has control. The circuit is prone to causing a "hollow" effect in the speech due to bandlimiting filtering in the audio paths.

IPC: C12R1/01
Filed: 1990-07-10
Abstract: A method for controlling and modifying biopolymer synthesis by manipulation of the genetics and enzymology of synthesis of polyhydroxybutyrate (PHB) and polyhydroxyalkanoate (PHA) polyesters at the molecular level in procaryotic and eukaryotic cells, especially plants. Examples demonstrate the isolation, characterization, and expression of the genes involved in the production of PHB and PHA polymers. Genes encoding the enzymes in the PHB and PHA synthetic pathway (beta-ketothiolase, acetoacetyl-CoA reductase and PHB polymerase or PHA polymerase) from Zoogloea ramigera strain I-16-M, Alcaligenes eutrophus, Nocardia salmonicolur, and Pseudomonas oleovarans were identified or isolated and expressed in a non-PHB producing organism, E. coli. Specific modifications to the polymers include variation in the chain length of the polymers and incorporation of different monomers into the polymers to produce co-polymers with different physical properties.
