A presser foot assembly for use with a workpiece support in a sewing machine having a sole plate, a body for supporting the sole plate in a position for pressing material to be sewn onto a workpiece support, and a lead-in sole part. The assembly has a pin for pivotally connecting the lead-in sole part to the sole plate, and a spring for moving the lead-in sole part between a first position adjacent the workpiece support and a second position spaced from the workpiece support.

Low-viscosity high-solids-content melamine-formaldehyde condensates having high reactivity, low content of free formaldehyde and good compatibility, are prepared by effecting condensation in an alcohol having up to 3 carbons, then concentrating the condensate and heating the concentrate in a higher alcohol having from 3 to 18 carbons and again concentrating. The final product cures on heating to a hard glossy film and can be added to other uncured resins to improve the hardness of their films.

A camera wherein a setting ring is rotatable by hand to select a desired aperture size and simultaneously moves a pointer with reference to an f-stop scale. An exposure time scale is movable along the f-stop scale together with a filter which influences the admission of light to a photoelectric receiver in an exposure time selecting circuit which causes a lamp to light up when the exposure time is too long for the making of exposures with the camera held by hand. The filter is also moved in response to rotation of the setting ring to thus influence the selection of exposure time as a function of the selected aperture size. If the user wishes to determine that exposure time which is automatically selected in response to selection of a particular aperture size, the exposure time scale is moved with the filter until the lamp lights up. The graduations of the exposure time scale then register with appropriate graduations of the f-stop scale and the user can look through the view-finder window to see that graduation of the exposure time scale which registers with the graduation representing the selected aperture size.
