A bicycle pump which has a pivoting footpeg on which the user may stand to secure the pump against the ground. The pump has a pivoting handle which includes a spring which forces apart the base and handle of the pump so that the pump can be secured in tension on a bicycle frame.

A hard copy such as a printed wiring board is fabricated by exposing to radiation a liquid crystal cell in which a desired pattern is written and directing the pattern-carrying radiation projected from the cell by transmission or reflection to a substrate which is coated with a material sensitive to the radiation and disposed alignedly at an exposure position by optical registration. The duration of the exposure is controlled for a given light intensity and for the type of the coating material. A pattern may be written in one cell substantially simultaneously as another cell is used for the projection imaging. After a produced pattern is compared with a reference pattern, corrections may be effected through a processor which controls the writing of a pattern in a cell.

Fabrication of printed wiring boards by projection imaging

An image projection apparatus in which an image object plane contains a plurality of reflecting images and a light source and optical system projects a beam on each of said plurality of images. Spaced projection lenses are positioned to receive the light reflected from the images and direct the light on a projection surface with the plurality of reflected images in coregistration.

An apparatus for projecting high precision optical images with a selective heating source, advantageously a laser, on a writable, erasable, editable electronic slide and simultaneously or sequentially projecting the images in registration, onto a receiving surface such as a projection screen or photosensitive material, in the former case for the purpose of displaying the projected image and in the latter case for the purpose of creating a hard copy of the projected image.

A multi-mode scanner head employing split (semicircular transducers) is described. In some modes such as simultaneous B-scan and M-scan each transducer moves independent of the other. For continuous Doppler mode the transducers move together. The relatively small, hand-held scanner head is particularly useful for cardiac examinations.

An automatic temperature control system for a textile tenter frame having an oven section for heating the fabric in order to 'set' its fibers in an essentially non-shrinkable state. The system operates to maximize the speed of the tenter frame while maintaining optimum heat set conditions. Fabric temperature from within the oven and initial moisture content data are furnished to a computer and processed with time-at-temperature target inputs to provide tenter frame speed control output signals.
