Abstract: A protection device for sewing machine includes a presser which has a first end connected to a presser bar and a second end of the presser has a through hole so that the needle reciprocally extends therethrough. A needle cover is connected to a top of the second end of the presser and no gap is defined between the needle cover and the top of the presser. The needle cover protects the user from being hurt by broken needle.

Abstract: The present invention is directed to antigenic peptides and peptide compositions selected from the Membrane glycoprotein (M), the Spike glycoprotein (S), and the Nucleocapsid (N) protein antigens of the SARS coronavirus (SCoV). The present invention is also directed to methods of use of the peptides of the invention, e.g., for the detection of SARS-associated antibodies. Detection methods include enzyme-linked immunosorbent assay (ELISA) or other immunoassay procedures.

Abstract: A sewing machine body includes a base with an upright part connected to a top of an end of the base and an arm which is connected to a distal end of the upright part. Each of the base, the upright part and the arm includes a hollow interior which is defined by four sidewalls or three sidewalls. Four connection plates are respectively welded to the arm and the upright, and the upright part and the base. The welding seams of the connection plates and the arm and the base are parallel to the arm.

Abstract: A sewing machine includes a main frame provided with a drive shaft, and a cutting mechanism mounted on the main frame and driven by the drive shaft. The cutting mechanism includes a driving device, a first retaining device, and a second retaining device. Thus, the cutting mechanism is operated rigidly and stably, thereby facilitating the user operating the sewing machine.
