Title: Automatic means for earthing the aerial of wireless installations
IPC: H01Q1/48
Filed: 1925-05-21
Abstract: 254,851. Elphick, P. May 21, 1925. Grounding aerials.-An electromagnetic relay is inserted directly in the filament circuit of a valve receiver for the purpose of automatically earthing the aerial when the set is switched off, and of connecting the set to the aerial when the valve filaments are lit. The relay is permanently biased in the aerial-earth position. As shown one or more electromagnets 7 are included in the low-tension circuit through terminals 8, and control the position of a rocker arm 3 carrying contacts 10, 12 co-operating with mercury cups or other contacts 11, 13. When the set is out of use, the contact 12 connects the aerial down-lead from the terminal 1 directly to the terminal 13 which is earthed. When the valves are switched on, the rocker arm swings over to connect the terminal 1 with the terminal 11, which is joined to the aerial terminal on the set, simultaneously breaking the earth connections at 13. A loop 9 on the rocker arm acts as a lightning choke. The whole device is preferably enclosed in a weatherproof box located outside the building.

Title: Image motion compensator
Inventor: CIERVA JUAN DE LA
IPC: G02B27/64
Filed: 1964-04-01
Abstract: 1,056,527. Optical apparatus. DYNASCIENCES CORPORATION. April 1, 1964, No.13341/64. Heading G2J. Optical systems associated with aerial and space vehicle photography, navigation and observation, are stabilized for random angular movement by means of a variable angle prism. As shown the prism is formed by a fluid 18 sealed at 16 between a pair of glass plates 12, 14 supported at their edges by annular members 20, 22, which in turn are floatingly held by four pairs of arms, each arm comprising an internally threaded block 36 which is carried on a worm of a screw 24. A yoke 38 is pivotally supported about a horizontal axis on block 36 and carries a rod 40 extending into a radial blind bore 42 in annular member 20. Four screws such as 24 are provided and each has upper and lower threads reversed to each other and such that the upper thread of each screw is reversed to that of the upper thread of the diametrically opposite screw so that when a ring 52 is rotated, gear segments such as 54, rotate spur gears, such as 48, on screw 24, and a pair of opposed screws cause pivoting of plates 12, 14, about one axis to compensate for movement of the craft about one specific axis e.g. the pitch axis. Movement of the craft about the roll axis causes rotation of another ring controlling movement of the other pair of screws. In an embodiment wherein a camera has its image stabilized, the camera pitch and roll are sensed by rate gyros each feeding a prepositioner loop, which is also fed with the position of the plates 12, 14 as sensed by a transducer, to position the plates 12, 14, during the time that the camera shutter is closed. When the shutter is about to open a synchronizing pulse switches to an image motion compensator loop fed with the rate of change of prism angle as well as the output from the appropriate gyro so that the movement of prism angle during the actual exposure time is symmetrical with respect to the zero prism angle position and this gives the most uniform angular deviation of the prism for various incident ray angles. Information relating to the vehicle velocity divided by its altitude is fed into the pitch channel to compensate for longitudinal movement of the vehicle and film advancing arrangements to compensate for this movement are thus rendered unnecessary. As applied to a navigational device, Fig. 8 (not shown), in which a telescope having a photo-electric star follower is servo controlled to follow the sidereal motion of the star, the variable angle prism is positioned in front of the telescope and compensates for irregular angular motions of the vehicle.

Abstract: 1346493 Massage devices MATSUSHITA ELECTRIC WORKS Ltd 6 May 1971 [13 May 1970 (3)] 13396/71 Heading A5R A belt-type massage device comprises a body frame A, a foot base B pivotally mounted at one end on a lower part 18 of the frame, a motor 5 in a housing (7), Fig. 2 (not shown), a pair of swinging links 12 mounted to the upper part of the frame, coupling rods 13 for swinging the pair alternately with rotation of the motor, and a massaging belt (c) engaged with the pair of links for transmitting vibrations to the human body. In operation the foot base B is positioned on the floor in a slanting position and a supporting frame 22 placed against a stop 16. The belt (c), engaged at both ends via members (26) with a pair of link pins 11 1-3  on swinging links 12, is applied to that part of the patient's body to be massaged while standing on the foot base B. The rotation of the operating motor 5 causes a pair of eccentric rings 6, fixed at the ends of a shaft 4, to rotate eccentrically and create swinging motion of the links 12 through the coupling rods 13. This moves the links 12 alternately about the link shaft (3) and thereby vibrates the belt (c). Vibrating motions of different amplitudes may be generated by coupling the belt to any single pair of link pins 11 1-3 . After use the supporting frame 22 is removed from stop 16, rotated into the frame A with base B and shaft rod 19, and the device carried on wheels 20 to a storage place..

Title: Improvements in acoustic depth-sounding and measuring installations for ships and air-craft
IPC: G01S7/526
Filed: 1924-06-02
Abstract: 236,023. Behm, A. June 2, 1924. Determining distances acoustic - ally. - In apparatus for sounding depths by timing or measuring the intensity of echoes, the extent to which the detector is screened by the hull from the outgoing sound can be varied in accordance with the depth to be measured. Arrangements for testing the apparatus are incorporated. Thus a sound emitter located forward on the port side may be used for shallow depths in conjunction with a detector located forward on the starboard side, or for deeper water in eonjunction with a detector located aft on the starboard side. This arrangement is permitted by the fact that less screening is required for shallow than for deep water since weaker sounds can be employed, while it is desirable for the emitter and detector to be closer together in shallow water in order to reduce the obliquity of the sound path. A shorter wave-length may however be used to increase the screening effect in shallow water. According to a modification there may be a single detector and two alternative emitters: or there may be two emitters at different levels on the ship's side, and two detectors similarly arranged. In the arrangement shown in Fia. 4 an emitter G is fixed in the bottom of the ship and an emitter E is mounted in the ship's side in such a way that it can be projected more or less according to the depth, position I being adopted when the bottom is at R, and position II when the bottom is at R2; or both emitter and detector may be adjustably mounted on opposite sides of the ship. For testing purposes the emitter may be mounted at one end of the ship and several detectors E1, E2, E2, may be arranged at intervals along the side, so that the emitted sound will reach them at different times. and the apparatus should indicate corresponding depths : alternatively a conduit S, Fig. 6, inside the ship, may contain spaced detectors E4, E5, E6, adapted to control a timing device when influenced by sound coming from an inload retransmitter G2 adapted to be excited on the emission of a sound at G1. In the case of a submarine, the detectors may be screened by the hull from echoes coming from the surface.
