Abstract: A combination car system is made up from a first car (1) and a second car (101), both of which are capable of running independently. The first car (1) includes a pair of front wheels (3) by which it is driven, a pair of rear wheels (4), a first engine, and a first transmission which drivingly couples this first engine to the front wheels (3). The second car (101) includes a pair of front wheels (103), a pair of rear wheels (104) by which it is driven, a second engine, and a second transmission (not shown), which drivingly couples this second engine to the rear wheels (104), and which is an automatic transmission which can be set to at least N, D, L, and R ranges according to the position of a switching valve. The first car and the second car are couplable together into a combination car (10) which runs on the front wheels (3) of the first car and on the rear wheels (104) of the second car, the rear wheels (4) of the first car and the front wheels (103) of the second car being at this time removed from road contact. At this time, an electrical connecting system provides control by a first electrical switching system (78-81) fitted in the first car to an electrically operated servo device which positions the switching valve of the automatic transmission of the second car to any one of the above ranges. On the other hand, when the cars are running independently, at this time the electrical connecting system provides control by a second electrical switching system (178-181) fitted in the second car to this electrically operated servo device. Thus, when the cars are coupled together into the combination car, the operation of the automatic transmission of the second car may be controlled from the first car.

Abstract: The device comprises a hollow body (1) in which is provided a reservoir of material to be sprinkled, a hollow sprinkling head (10, 11) of lenticular form provided with orifices along its periphery, and a dispenser (15, 16) nesting over the body (1). The base of the reservoir has two holes (6, 7). The dispenser has two chambers of calibrated volume (17, 18) which are open at their two ends. A flap (19), pierced by a perforation (21), is rendered integral with the body (1) when the various elements are assembled by means of a screw (20). The dispenser (15, 16) can be hand actuated in order to give it a rotational alternate relative movement, at a very specific angle, about the axis of the device. In one of the extreme positions of the dispenser, the chamber (17) is placed in communication with the reservoir via the hole (6), whilst the other chamber (18) is placed in communication with the head (10, 11) by the perforation (21). In the other extreme position, it is the chamber (18) which is connected to the reservoir via the hole (7), whilst the chamber (17) is then connected to the sprinkling head via the perforation (21). Thus, by actuating the device, a unit of material which is equal to the volume of one of the chambers (17, 18) is caused to fall into the head (10, 11) on each stroke, which makes it possible to accurately measure the sprinkling. <IMAGE>

IPC: B60R1/078
Filed: 1980-11-18
Abstract: An external rear-view mirror assembly comprises a pair of caliper-like clamping arms (10, 12) articulated to each other and a mirror-mounting stem (50) which projects from the articulation joint of the arms. The two arms (10, 12) are retained in an articulated condition by releasable retention means (102, 98). Each arm (10, 12) has a respective radial wall (78, 80) at its end (74,76) which articulates with the other arm. At least one of the walls has a circular array of notches (114, 116) concentric with the articulation axis (X-X) and the other wall has at least one corresponding notch. The arms (10, 12) are biassed towards each other by a helical torsion spring (108) which is coaxial with the articulation axis (X-X), and is interposed between the radial walls (78, 80) in such a way that a respective outwardly facing axially projecting end (110, 112) of the spring engages a notch of the adjacent radial wall (78, 80). Release of the retention means (98, 102) enables the disengagement of the projecting ends (110, 112) of the spring (108) from the notches (114, 116) and their subsequent engagement in other notches to vary the angle between the arms (10, 12) corresponding to the relaxation condition of the spring (108).

Abstract: A source of radiation irradiates an area of interest of a patient. An image intensifier receives the x-rays which have traversed the patient and provides an optical image of an x-ray shadowgraph through the examined area of the patient. A television camera converts the optical image into a video signal. A signal processor operates on the video signal by adding an offset signal to the gray scale signal and by logarithmically compressing the gray scale portion of the video signal. An automatic zero circuit is provided which readjusts the offset signal between each horizontal sweep of the television camera. The logarithmically compressed gray scale portion of the video signal and the synchronization portion are received by an image processor. The image processor digitally stores a mask image or shadowgraph of the patient before being injected with an x-ray opaque contrast agent. The image processor also stores in a post contrast image or shadowgraph of the same area of the patient after the patient has been injected with an x-ray opaque contrast agent. The image processor processor subtractively combines the mask image with the post contrast image to produce a difference image. A video monitor displays the difference image.
