Filed: 1962-08-16
Abstract: 1351933 Camouflaging ships against radar detection ELTRO GmbH 16 Aug 1972 [17 Aug 1961] 31570/62 Heading B7S [Also in Division H4] In a ship having surfaces which reflect electromagnetic waves, the cross-sections of the substantially vertical surfaces of the individual components of the ship and of the deck superstructures differ by at least 3 degrees from a right angle in relation to the horizontal surfaces or in relation to the water surface. It is explained that surfaces at right angles reflect radar radiation strongly in the incident direction, whereas if the surfaces differ from a right angle by at least 3 degrees, and preferably between 10 and 20 degrees, the reflection in the incident direction is reduced. The surfaces may be at least partly parabolic in section, and large wall surfaces are preferably sub-divided into individual facette-like areas which are curved concavely along the axes of the surfaces. All surfaces longer than 1 metre in one direction are preferably curvilinear in this direction. The vertical side surfaces of the ship are preferably so shaped that rectilinearly propagated radiation impinging at an angle of 0 to 10 degrees from the horizontal is reflected so that it impinges on the water surface at a distance of 3 to 30 metres from the ship where the water is normally disturbed by the ship's movement. Surfaces participating in multiple reflection may be made of or covered with material which abosrbs electromagnetic waves. Fig. 5, shows a diagrammatic sectional view of the side of a ship and a deck structure, the path of incident radiation and reflected radiation being shown by arrows R and Z respectively. Figs. 7a and 7b show respectively a side elevation and plan of a deck-house.

Applied by backward pressure of tractor or relaxation of pull.-Relates to apparatus for automatically applying the brakes of motor-towed and animal-drawn vehicles and it may be also of the motor-tractor upon the slowing down of the tractor vehicle or animal. Fig. 2 shows one arrangement applied to a motor wagon and comprising a bar 1 sliding in a box 6 secured to the wagon frame 7. A cable 5 attached to the brakes passes round a pulley 4 mounted on the bar 1 and is secured to the box 6. The bar 1 is attached by the parts 2, 3 to the towed vehicle. A similar arrangement may be disposed on the front end of a towed vehicle. Springs for taking up shock and for returning the bar 1 after the brakes have been applied may be disposed between abutments on the bar 1 and the box 6 to prevent application of the brakes when backing the vehicles. Various forms of mechanical connection between the sliding bar and the cable attached to the brakes are described. Thus the bar may be pivoted to a simple lever having also a fixed pivot and attached at one end to the cable. This and the pulley device shown in Fig. 2 may be combined by attaching the end of the cable to the end of the lever instead of to the box 6. Fig. 10 shows a pair of levers 20, 23 pivoted together at 26 and to fixed points 21, 25. Or the sliding bar 18 may have rack teeth geared to a drum 23, Fig. 12, or an eccentric to which the cable 22 is attached or to a lever 30 with toothed sector, Fig. 14, or to a gear wheel to which is geared a second rack bar attached to the cable.

Abstract: 618,169. Gauging-apparatus. P.A.M., Ltd., and HOLT, H. B. W. Oct. 30, 1946, No. 32186. [Class 106 (ii)] A linear - dimension gauge comprises a housing carrying a movable work - engaging plunger and a contact and valve amplifying means adapted to operate an indicator when the gap between the plunger and contact is closed. The housing 4 has detachable end pieces in the' lower of which is slidably mounted the plunger 6 having a flat contact extension for cooperation with a sphericallyground contact-end 5 of a rod 15 mounted in an insulating bush. The contact-pieces are polished and plated and the rod 15 is connected by a flat spring 17 to a rod 18 also mounted in an insulating bush, a screw 22, having a dial 25 and an insulating tip 23, being provided to bow the spring and so to adjust the contact 5. The grid of a triode-diode valve V1 is normally supplied with an A.C. signal derived from a potentiometer R1, R2, which signal is amplified and rectified by the diode to produce a negative potential which is applied to the grid of a triode V2 to bias it beyond cut-off. However, when the plunger 6 engages the contact 5 in a gauging operation, the resistance R2, the ends of which are connected to the rod 18 and to the housing 4 respectively by a cable 7, is short-circuited so that the negative potential is removed from the grid of the valve V2 which then becomes conducting to cause a relay 1 in its anode circuit to close the circuit of a visual or aural indicator. On an alternative circuit (not shown, for universal valves, the valve V2 is a tetrode and the relay 1 is connected in the cathode circuit. To simplify servicing of the amplifiers, the resistances and condensers, the relay and, if used, the transformer and the metal rectifier may be built into sealed boxes adapted to plug into valve-holders secured to the chassis.
