Patent CA-2111553-A1 (CA)
Inventor: HELGESEN GARY D
IPC: F02F7/00
Filed: 1993-12-15
Abstract: Abstract of the Disclosure A method for manufacturing an engine block by sand mold casting techniques wherein the cylinder bore liners are recessed from the cylinder head contact surface of the engine block is provided.  The outer surface of each cylinder bore liner has at least one circumferential groove formed therein.  The cylinder liners are initially positioned in a barrel core box and a barrel slab core is formed by blowing resin coated sand into the core cavity of the barrel core box.  Each liner is positioned in the barrel core box such that the groove remains free of sand during the core making process.  The barrel slab core is then combined with other conventional core assemblies to form a cylinder block mold.  The cylinder block mold is filled with a light alloy metal to produce an engine block casting with caste-in-place cylinder bore liners.  The top end of the cylinder bore liners may be cast above or flush with the cylinder head contact surface of the engine block casting.  The cylinder bore liners and the cylinder head contact surface are subsequently machined to produce an engine block wherein at least one cylinder bore liner is recessed from the cylinder head contact surface.  The machining operations may include milling the top end of the cylinder bore liners and rough boring the inner surfaces of the cylinder bore liners.

Abstract: An overshoe or weather-protective shoe has a hollow reservoir contained within its sole and a concave recess located beneath the reservoir. When the wearer steps into a puddle or onto a wet surface, water is drawn into the reservoir by a suction effect produced by the action of the concave recess. Water accumulated in the reservoir subsequently passes through water-channeling means contained within the overshoe or weather-protective shoe and is squirted in a jet from the front top portion of the shoe. The invention may further include a toe-actuated exit valve allowing the wearer to control the timing of the squirting action.

Title: Controlled pulse operating circuit system for a discharge lamp, typically a sodium high-pressure discharge lamp, from an a-c power network
Inventor: BOENIGK MICHAEL
IPC: H05B41/392
Filed: 1995-04-03
Abstract: To provide for effective control of a discharge lamp, typically, a sodium high pressure discharge lamp, which operates in two phases, namely, a power pulse phase, followed by a holding phase, without extensive and complex electronic circuitry, two individual oscillator systems are provided, one for each phase; the oscillator systems include a first power burst oscillator formed as a first half bridge by two transistors (T1, T2), and an individual connecting current limiting inductance (L1) to the lamp (E), and a second oscillator including a two-transistor second half bridge (T3, T4) and an individual current limiting inductance (L2) coupled to the lamp.  The respective oscillators are controlled, in a closed control loop, by a burst generator (BG) and a holding pulse generator (SG), each of which provide their signals to a logic circuit (LK) which provides for exclusive control of the respective first or second half bridge. A lamp voltage sensing circuit (C4, R2) taps lamp operating voltage, which is compared with a command signal to control through a repetition frequency control generator (WG), the recurrence rate of the bursts from the power bursts generator (BG). The lamp starting circuit (4) can also be controlled from the sensed signal by comparison with a reference in a second comparator (K) and suitably applied to an ignition circuit by an ignition monitoring logic.  A pair of electrolytic capacitors of essentially the same value is connected across the d-c supply and their midjunction to the lamp.

Inventor: TURNER PAUL H
IPC: F16F9/16
Filed: 1995-06-05
Abstract: Shock absorbing fork, especially a front fork, for a two-wheeled vehicle, particularly a bicycle, of the type having a pair of telescoping struts and a hydraulically damped shock absorbing arrangement disposed within each of the telescoping struts, the shock absorbing arrangement having a piston which divides a hydraulic fluid containing cylinder into upper and lower chambers, a valve regulating flow of hydraulic fluid through the piston between the upper and lower chambers, and a piston rod connected to the piston. Among the improvements of the invention is the provision of a spring for absorbing shocks that acts on the piston of the hydraulic shock damping arrangement upon compression of the telescopic struts, and a location sensitive flow control arrangement having a flow path extending between opposite sides of said piston and a flow adjusting element which is displaceable into and out of said flow path as a function of the extent which the spring is compressed by compression of the telescopic struts. As a result, flow through the flow path is progressively changed as the struts are compressed and the damping characteristics of the hydraulic damping arrangement are progressively varied. Furthermore, a compression damping adjuster shaft having an axially adjustable abutment member thereon to hold the resilient pad against a spring disc of the compression valve of the piston under a holding pressure which is adjustable by axial displacement of the abutment member. Additionally, the entire hydraulically damped shock absorbing arrangement is formed as a self-contained replaceable cartridge unit.

Title: Process for producing a container covered with a cylindrical heat shrinking film and apparatus for producing said container
Inventor: SUKEYASU RYUZO
IPC: B65B9/13
Filed: 1995-06-26
Abstract: A process for producing a container covered with a cylindrical heat shrinking film comprises preparing a continuous double layer sheet of a heat shrinking film by folding a continuous single layer sheet supplied from a roll, sealing the open side of the continuous double layer sheet by heat, cutting the continuous double layer sheet to form a cylindrical heat shrinking film having two open ends, disposing the cylindrical heat shrinking film around periphery of a container in an upright condition after moving past outside of floats, cutting and sealing an upper part of the film by heat to a shape of an arc without removing the film from the container to form a heat shrinking bag film, pulling down the film until the sealed part is brought into contact with top of the container, allowing a lower part of the film to shrink by partial heating to bring the heated part tightly into contact with bottom of the container, and heating the whole film to bring approximately the whole film tightly in contact with the whole container while the container is kept in the upright condition. An apparatus for the process is also disclosed. A packaging line can be remarkably improved because the cylindrical heat shrinking film can be produced in the line. Shrinking ratio of the film can be decreased because a film of a size close to the container can be easily used. Appearance of the product container can be kept the same on all sides because the container can be transferred in an upright condition. Deformation of characters and patterns printed on the film can be avoided. Therefore, a container covered with a heat shrinking film of beautiful appearance can be produced efficiently.
