Title: Unfoldable boat roof having a passive locating device
Inventor: PETERS HENNING
IPC: H01Q15/18
Filed: 1981-09-29
Abstract: In an unfoldable boat roof, preferably forming an integral part of an inflatable life raft, a passive locating device is comprised by a foldable localization reflector which is set in place upon unfolding the roof body. To this effect, heretofore a triple mirror was placed on the roof, the outer edges of such roof being provided with pipes which are also filled during the inflation of the raft and provide for the unfolding of the reflector. The problem results in that the reflector, due to its weight, shifts upwardly the raft load and that, during the destruction of the pipes for unfolding the mirror, the locating device is out of use. Therefore, the aim of the invention is to provide a locating device which is free of parts which may be easily damaged and which reduces the load placed on top. To this effect, bar shaped elements (15, 16) are arranged along the edges adjacent to the reflection surfaces (12, 13), those elements being connected on the one hand to the body of the roof (10) and the other hand between each other, in the same way as in an umbrella skeleton, to the central point (14) of the reflector (11) so as to diverge from each other.

Title: Ultrasonic radiometers
Inventor: ANSON LESLIE WILFRID
IPC: G01H3/10
Filed: 1982-06-15
Abstract: An ultrasonic radiometer comprises a fluid container (2) in which a target assembly (14) is completely submerged in a fluid (4). The target assembly (14) is held submerged in the fluid by three tethers or flexible lines (24) each secured at one end to the base of the container. In this way the target assembly (14) is suspended so that it is neutrally buoyant. An ultrasonic radiation source (28) is directed at a conical surface (22a) of the target assembly. The downward radiation force on the target assembly is counteracted by means of a magnetic force applied to the assembly by a coil (10) which is disposed around a magnet (20) which depends from the target (22a). The magnitude of the current which is supplied to the coil (10) to restore the target assembly (14) to its null position provides an output indication of the magnitude of the ultrasonic energy to which the target is subjected. <IMAGE>

Title: Controlling the movement of a reciprocatory hydraulically driven element of a metal forming machine
Inventor: HACKETT KENNETH PAUL
IPC: B21C23/04
Filed: 1982-06-23
Abstract: The element has a first piston part 242, a first reservoir 247 slidably receiving said first piston therein, said first piston having a face disposed in fluid communication with said first reservoir, a second reservoir 259, a second piston part 262 secured to and projecting from said face of said first piston, said second piston being slidably received within said second reservoir when the element is retracted. The second piston moves outside said second reservoir during element extension. Since the face of said first piston has a larger working area than the working surface area of said second piston when the second piston leaves its reservoir and enters the first reservoir, the speed of extension decreases. A source of pressurized hydraulic fluid communicates with said first and second reservoirs. A third reservoir 245 on the opposite side of the first piston communicates with said first reservoir via a valve. <IMAGE>

Title: Protective circuit system for emergency light
Inventor: LIN MIN-SHIN
IPC: H02J9/02
Filed: 1983-06-28
Abstract: An emergency lighting system includes means to prevent over-charging and over-discharging of its battery VB. When the mains AC supply is present, relay CR1 is energised to close contacts CR1a to charge the battery VS from rectifier S1. When the battery voltage reaches a preset level, a transistor Q1 energises a relay CR3 thereby opening contacts CR3b to stop battery charging by turning off a bias G in the primary circuit of a charging transformer Tr. If the AC mains fails, transistor Q2 turns on relay CR2 to close contacts CR2a so that the battery VB discharges into the lamp RL until the battery voltage falls below the threshold set by Zener diode ZD3 whereupon transistor Q3 turns off to de-energise relay CR2 and stop discharge of the battery. If the ambient illumination is above a certain level when the mains supply fails, a photocell Cds prevents transistor Q2 turning on thereby preventing discharge of the battery VB into the lamp RL. <IMAGE>
