Abstract: During operation of a construction vehicle, such as a wheel-loader, the operator may desire to open the door of the vehicle's cab for ventilation purposes. Full opening of the door may be obstructed by the deposition of a guard rail or the like, mounted on the platform of the cab, whereby the door can be only partially opened. It is thus desirable to provide a door holder which may be selectively positioned on the platform to hold the door in any desired, open position. In addition, standard latch mechanisms for holding a door of this type in its fully open position are generally mounted externally on the cab and are thus exposed to potential damage. The door holder (13) of this invention includes a latch member (14) movable between retracted and extended positions on the vehicle, and a hook (27) secured on a door (11) for engaging the latch member when the door is in open position and the latch member is in its extended position.

A forked tongue having a slot for guiding the biasing spring extends upwardly from the latch sled and is also formed during the stamping process. The slot which is formed during the stamping of the forked tongue is notched to provide securing of the housing spring.

Abstract: A lens based on the concentration of electro-magnetic radiation through combined reflective and refractive properties of the lens. In one form of the lenticulated lens, radiation impinges and is transmitted through a substantially planar frontal surface. The incident radiation subsequent to being transmitted through the frontal surface impinges on a rear inclined surface forming a portion of the lenticulated rear surface of the lens. The ray is reflected from the mirror coated inclined surface and is egressed from the frontal surface and is refracted to a focus line. The incident rays impinging on the frontal surface are thus directed to the linear focus line when the lenticulations of the lens are linearly directed. By providing refraction and reflection passage of the incident rays from and through the lens, the reflected portion of the incident ray which is focused to a line focus is maximized.

Abstract: A photographic copying machine wherein copying light which issues from a light source and is directed toward an original is caused to pass through a light intensity weakening shutter of the venetian blind type. The shutter is adjusted to change the rate of passage of light therethrough in dependency on the intensity of signals which are generated by the exposure control system of the copying machine and denote the anticipated exposure times in the red, green and blue colors. If the anticipated exposure times are too short, the intensity of copying light which impinges upon the copying material is reduced by a stepwise adjustment of the venetian blind type shutter. Inversely, the shutter is caused to permit the passage of more light if the signals which are generated by the exposure control system denote a relatively long exposure times in the three colors.
