Patent CA-2035014-A1 (CA)
Inventor: GORDIN MYRON K
IPC: E04C3/30
Filed: 1991-01-25
Abstract: A means and method for rigidly elevating a structure (18) includes a base member (60) securable in the ground and which has a portion extending above the ground (24). A pole section (66), having a bore (68) inside a lower end, and an upper end, can be stacked upon the base means upwardly by slip fitting the pole section onto the base end and securing it in place. A flexible, easily transportable and durable system is thereby created for elevating structures. <IMAGE>

Abstract: ABSTRACT OF THE DISCLOSURE         In a television receiver, a change in a horizontal frequency of an input television signal between a high frequency and a low frequency is detected.  A horizontal oscillation frequency, a horizontal deflection drive pulse width, and a horizontal blanking period are changed in a first predetermined sequence in response to a change in the horizontal frequency of the Input television signal from the high frequency to the low frequency.  The horizontal oscillation frequency, the horizontal deflection drive pulse width, and the horizontal blanking period are changed in a second predetermined sequence in response to a change in the horizontal frequency of the input television signal from the low frequency to the high frequency.  The first and second predetermined sequences are opposite to each other.

Abstract: HIGH SPEED TRANSPORT PROTOCOL WITH TWO WINDOWS Abstract A packet transmission protocol, which operates in a full-duplex mode in a system, which includes a transmitter, a receiver, and a communications networkhaving a channel that logically ties the transmitter and the receiver together through the network, is disclosed. The receiver regularly sends a control packet to the transmitter. The control packet includes a plurality of data fields, which are useful in describing the state of the receiver to the transmitter. The transmitter receives the receiver's control packet and analyzes the data. If it finds that a particular block of packets had been received with an error (or not received at all), then the transmitter retransmits the block. The protocol includes two windows for controlling the volume of information, e.g. number of blocks, in the network. The first window, called thenetwork window, is used to limit the data in the network so that network buffer resources can be sized economically and yet in a manner such that there will not be an excessive loss in the number of packets transmitted through the network. The second window, called the receiver flow control window, is typically larger than the first window and is used to assure that packets are not dropped, or lost, at thereceiver. By having the second window larger than the first window, throughput can be increased while still meeting a commitment to the network that limits the number of packets in the network to a value consistent with economical buffer sizing. Typically, the first window is set to the value of the bandwidth delay product of the channel and the second window is set to a value at least twice that of the firstwindow. The functions related to receiver flow control and network congestion control can be decoupled.

Inventor: CHIEN SHI-HAI
IPC: A63H31/00
Filed: 1991-03-06
Abstract: Disclosed is an improved variable speed transmission system adapted for, in particular, an electrically powered vehicle.  The system is operated by a common manual gear shift.          The manual gear shift has a power source made up of a specially designed electric motor having a rotatable outer shell which is relatively moveable with respect to a core rotor so that the power from the rotatable outer shell and from the core rotor of the electric motor can be output respectively to front and a rear differential gear devices, and the vehicle can be powered to move via the differential gear devices.  Respective transmission shafts between the electric motor and the front and rear differential gear devices can be selectively locked so that the power from the motor to the differential gear devices can be selectively varied so that the rotational speed of the wheels of the automobile can be varied.

Title: Use of autologous promoters to express gene products in bordetella
Inventor: LOOSMORE SHEENA
IPC: A61P31/04
Filed: 1991-04-16
Abstract: Autologous promoters are used to effect expression of gene products in pertussis strains.  Hybrid pertussis genes are constructed comprising a structural pertussis gene fused at an ATG codon to a native but autologous pertussis promoter.   B. pertussis, transformed by the hybrid gene by  insertion  into the chromosome of the organism by homologous recombination at specific loci, effects expression of the antigenic protein for which the  structural  gene  codes  at  a  production  rate different from that achieved for the homologous gene. Specific  strains  and  plasmids  are  descibed.    The technique  is  applicable  to  a  wide  variety  of  gene products and organisms.

Abstract: Forming devices in packaging machines of the type which reforms tubular packaging material of substantially circular cross-sectional configuration into individual package containers of quadrilateral cross-sectional configuration normally consist of pairwise cooperating forming flaps which are of U-shaped cross-section. In order to prevent the packaging material from being pinched between the shank surfaces of the flaps when the flaps are caused to surround the packaging material tube, the shank surfaces are designed to be undulatory, i.e. alternatingly with projections and recesses which fit in one another and guide the packaging material tube into the U-shaped recesses of the flaps without pinching the packaging material tube.

Title: Method and apparatus for clarifying liquid using a pulsating sludge bed and part of concentrated sludge
Inventor: BALLARD P TEMPLE
IPC: B01D21/00
Filed: 1992-02-18
Abstract: There is disclosed a pulsating sludge bed clarifier especially for the treatment of low turbidity waters, which uses incline plates in the sludge bed and some recirculated sludge.   The clarification is greatly enhanced by recirculating a relatively small part of the sludge concentrate to a reactor chamber used for the premixing of water to be treated and the coagulant.  The small amount of recirculated sludge cuts down significantly on the polymer flocculant, which is the most expensive chemical in the process that is required to be used, and can also serve to improve the adsorption of colors and similar materials,  increase the density of the sludge blanket, and improve the rate of throughput of the system.
