Patent CA-2452565-A1 (CA)
Inventor: WANG NUI
IPC: F16D65/54
Filed: 2002-08-30
Abstract: A drum brake assembly which includes a rotatable drum having a radially inner drum braking surface and a brake shoe (102) of single piece construction and of generally circular form mounted within the drum and against a backing plate (111). The brake shoe includes friction lining (107) and at least one flange (126) projecting radially inwardly. The brake shoe (102) has positioning means for positioning the brake shoe (102) within the drum in an inoperative condition against lateral movement into engagement with the drum braking surface, to provide for complete clearance between the friction lining (107) and the drum braking surface in the inoperative condition. The positioning means includes engagement means (131, 132) for engagement with abutment means (130). The abutment means (130) includes radially inner and outer abutments (134, 135) and the engagement means (131, 132) is arranged for engagement with the radially inner abutment (134) in the inoperative condition of the assembly to position the friction lining (107) away from the drum braking surface, and with the radially outer abutment (135) when the brake shoe (102) is radially expanded to the operative condition of the assembly. One of the engagement means (131, 132) or the abutment means (130) is formed as a displaceable member (133) which is displaceable radially relative to the brake shoe flange (126) or backing plate (111) for the purpose of maintaining the set running clearance between the friction lining and the drum braking surface upon lining wear. Engagement between the engagement means (131, 132) and the abutment means (130) in the inoperative condition is facilitated by biasing means (136) which biases the brake shoe to return to the inoperative condition. The biasing means may include the shoe undergoing resilient distortion to function as a return spring or it may include bias springs which act on the shoe.

Title: Medical needle device having winged shield for preventing accidental needlestick
Inventor: KUNITOMI JUN
IPC: A61M25/06
Filed: 2001-10-11
Abstract: A medical needle device includes a winged shield (4) having a substantially cylindrical shaped shield cylinder (4a) and wings (5, 6) connected to the front end side thereof, a needle base (2) inserted in the shield cylinder (4a), and a needle (1). The wings have wing projections (7, 8) and the shield cylinder has through holes (9, 10) on the wall thereof. By overlaying the wings along the side surface of the shield cylinder, each of the wing projections can be inserted into the inner cavity of the shield cylinder via the through hole. Thereby, without requiring a special operation in the sticking operation, each of the wing projections can prevent the needle base from moving in the axial direction and can hold the needle base in the shield cylinder reliably in a state in which the needle protrudes from the front end of the shield cylinder by a predetermined length.

Abstract: A method for formation of shaped components such as shaped absorbent cores, for disposable absorbent articles, contemplates that a relatively wide web of material be provided from which the components are cut. The web of material is longitudinally slit to form a plurality of subdivided webs each having shaped components arranged in serial relationship. The shaped components of adjacent ones of the subdivided webs are nested with each other, that is, a line extending longitudinally of the web extends through the components of adjacent subdivided webs. Efficient formation is facilitated by collecting the marginal portions of the web of material, and at least partially recycling the collected portions for formation of the wide web.

Title: Method of separating ions
Inventor: THEKKADATH GOVINDANUNNY
IPC: H01J49/16
Filed: 2004-06-25
Abstract: A method of separating ions, including a first species of ion and a second species of ion that are transmitted through an analyzer region under substantially identical electrical field conditions, is provided. The method includes separating ions within an analyzer region according to the FAIMS principle, such that the first species of ion and the second species of ion are selectively transmitted along a time-averaged first direction through a portion of the analyzer region between the ion origin end and the ion detection end. Subsequently, the first species of ion and the second species of ion within the analyzer region are separated according to a difference in low field ion mobility values, such that relatively more of one of the first species of ion and the second species of ion is transmitted to an ion detection end than is transmitted absent separating the first species of ion and the second species of ion within the analyzer region according to a difference in their low field ion mobility values. The ions are transmitted through the remainder of the analyzer region under normal FAIMS operating conditions.
