Title: Sewing machine
Inventor: MORI HIROKI
IPC: D05B29/02
Filed: 2023-06-27
Abstract: In a sewing machine, a feed dog feeds a workpiece placed on a throat plate. A presser bar has a lower end portion on which a presser foot is mountable. A presser bar spring urges the presser bar downward. During a first prescribed period of time in which a top of the feed dog is above a top surface of the throat plate, an adjustment part of an adjusting mechanism is spaced apart from a restricting part of the adjusting mechanism to cause an urging force of the presser bar spring to be transmitted to the presser foot. During a second prescribed period of time in which the top of the feed dog is beneath the top surface of the throat plate, the adjustment part is in contact with the restricting part to prevent the urging force of the presser bar spring from being transmitted to the presser foot.

Abstract: Carburetor components and carburetor providing a uniform mixture of fuel and air by a high degree of atomization of the fuel. The carburetor comprises an upstream air valve (11) and a downstream throttle valve (30) which is positively controlled to regulate the engine. Engine suction acts on the air valve to control the relative air and fuel flows. Fuel discharge orifices (22) are provided in the surface of the air valve (11) and movement of the air valve (11) is such that the orifices (22) are always located in a region of the intake path where the airflow is highest. This provides for good atomization of the fuel and hence the generation of a uniform air fuel mixture for delivery to the combustion chamber or chambers. 
     The air valve preferably takes the form of a flap pivotable about an axis such that a remote edge (21) thereof moves towards and away from a wall of the carburetor body (1). The fuel discharge orifices (22) are normally formed in the edge (21) and a manifold (23) distributes fuel thereto from ducts (24) also formed in the valve (11) communicating with a bore (26) in a shaft (25) defining the pivotal axis of the valve (11). The flap may be formed in two parts secured to one another to define the various fuel passageways.

Abstract: There is disclosed a normally closed solenoid valve (Figure 1) arranged to remain in an open condition notwithstanding reverse fluid flow through the valve. The valve includes an outer casing (14) having a first bore means (32) and a second bore means (34). A poppet (16) within the casing (14) is movable between open and closed valve positions. The poppet (16) includes an input orifice (42) and an output orifice (46). A plunger (18) forces the poppet (16) into the closed valve position while blocking its output orifice (46) and unblocks the output orifice (46) for permitting the poppet (16) to move into the open valve position. Fluid flow restricting means (20) disposed between the output orifice (46) and the second bore means (34) restricts fluid flow between the output orifice (46) and the second bore means (34) to one direction to permit the valve to open while precluding the valve from closing upon reverse fluid flow through the valve from the second bore means (34) to the first bore means (32).

Abstract: The invention provides a coupling for coupling pipe sections (10,12) end to end the coupling including a loose restraining ring (52) which does not function until the coupling is put under a stress which tends to move the pipe section ends axially apart, in which case abutment surfaces of the ring engage abutment surfaces (54) fast with the respective pipe section ends, thereby to limit other movement of the pipe section axially apart. The ring is-preferably of U-shape and cross section, with the limbs of the U-shape extending inwards, and the ring may have slots or cut outs alternating from the respective sides in order to improve the flexibility and expansibility of the ring.
