Title: Improvements in Differential Pressure Measuring and Integrating Instruments for Ships' Logs.
Inventor: AHNSTROEM ERIK GUSTAF
IPC: G01P5/17
Filed: 1918-01-08
Abstract: 112,623. Ahnstrom, E. G., and Tenow, O. A. A. Jan. 2, 1917, [Convention date]. Integrating. - In pressuresdifference logs or speed indicators for ships in which the integral of the speed is transmitted as an indication of the distance travelled to a distant instrument, the speedindicator controls the time interval between successive actuations of a switch controlling the operating-circuit of the distance-indicator. The pressure gauge of the speed-indicator comprises chambers 3, 4, Fig. 2, connected to a Pitot-tube or the like and separated by a diaphragm 2, and packing 6 surrounding a pin 5. The movements of the pin are transmitted through multiplying gear 7, 11 to a pointer 14 moving over a speed dial. The support 13 of the pointer is provided with a part 16 curved empirically to produce a deflection of an arm 20, Fig. 3, loose on a shaft 18, dependent on the speed. This arm is held in engagement with the curved member 16 by a spring 22 and counter-balance 21, and carries a contact 19 adapted to close against a contact 26 on an arm 25 carried by an armature 23 of an electro-magnet 24. When the electro-magnet 24 is de-energized, the armature 23 and the arm 25 move upwards under the influence of a spring 230 until the contact 26 meets the contact 19, thereby closing a relay circuit 35, 38 and the circuit of the' electro-magnet, Figs. 3 and 7. The armature 23 is thus attracted and the circuit of the relay coil 35 is immediately broken. A second coil 36, however, still maintains the switch 38 closed, until a contact 27 on the arm 25 meets a fixed contact 28, when it is short-circuited, thus breaking the circuit of the electro-magnet 24. During the time the electro-magnet is energized, a switch 33 controlling the circuit of a distant indicator 34 is maintained closed, and the indicator is advanced. The return upward movement of the armature 23 is controlled by clockwork or other braking device to ensure a uniform speed, the armature being put in gear with the clockwork through a ball clutch 30 and disk 29, Fig. 5. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the armature 23 is replaced by an electric motor rotating at a uniform speed and driving two worm wheels alternately, the contact arm 25 then moving uniformly in each direction This subject-matter does not appear in the Specification as accepted.

Title: Safety haulage rope clamp for a ropeway
IPC: B61B12/12
Filed: 1976-01-08
Abstract: 1497202 Safety haulage rope grip POHLIGHECKEL - BLEICHERT VEREINIGTE MASCHINENFABRIKEN AG 8 Jan 1976 [11 Jan 1975 14 June 1975] 00681/76 Heading F2X A safety haulage rope grip for a ropeway is in the form of an overload safety device between a haulage rope 1 of the ropeway and the carriage 11 of a ropeway cabin (not shown). Rope grip shells 4a, 4b engaging the rope 1 on opposite sides are disposed inside top and bottom rope grip jaws 3, 2 with a number of plastics strips 5, distributed over the periphery and length of the rope 1, being disposed between the shells 4a, 4b and the jaws 2, 3. A spring accumulator comprising three banks of springs 6a, 6b, 6c is mounted between the bottom jaw 2 and a connecting pressure plate 7, the latter being secured to the top jaw 3 by pins 61 on which the bottom jaw 2 is slidably guided. If the rope I ruptures, e.g. at place R, an axially directed force (arrow K) produced by the rope tensioning occurs, as a result of which considerable heating is produced at the contact surface between the shells 4a, 4b and the rope 1. In one embodiment, this heating causes the plastics strips 5 to melt, whereupon the spring accumulator is expanded and the shells 4a, 4b  hurled outwardly. This prevents the rope from becoming welded to the shells or at least the rough surface of the rope acting like a milling cutter on the shell surfaces. In an alternative embodiment, in which a different material is used for the plastics strips 5, the heating is such that the friction between the rope 1 and the shells 4a, 4b is substantially increased whereas that between the shells 4a, 4b and the strips 5 is only insignificantly changed, if at all. As a result, the friction becomes inadequate to maintain a connection between the jaws 2, 3 and the rope 1, and thus the shells 4a, 4b are hurled outwardly. In either embodiment, the number of plastics strips 5 is determined inter alia by rope diameter, the weight of the cabin, the weight conveyed by the cabin, and the polygonal design of the shells 4a, 4b. As illustrated, four strips 5 are distributed over the periphery of the rope at three places one behind the other, i.e. a total of twelve plastics strips. For the purpose of centring, the strips 5 are received in grooves in the jaws 2, 3.

Filed: 1940-01-13
Abstract: 538,757. Two-part couplings. BURROWS, H. Jan. 13, 1940, No. 770. [Class 38 (i)] A plug and socket coupling has split plug contacts formed as or associated with bi-metallic or other heat responsive elements so arranged that if heat is developed owing to faulty contact, the pressure between the interengaged parts is increased. The split plug, Fig. 1, may be formed of a central layer 1 of one metal and outer layers 2, 3 of a metal having a lower co-efficient of expansion so that the prongs 4, 5 move apart on heating. Alternatively a bimetallic strip may be placed between the prongs so that by its curvature on heating it forces the prongs apart. The plug may be formed from a bi-metallic blank, Fig. 3, bent to form contact prongs 4, 5 that move apart on heating. According to the Provisional Specification a socket may be similarly constructed, the parts moving towards one another on heating, a coupling having a pair of contacts may have each of them formed of a single bi-metallic strip so that the two contacts move towards or away from one another on heating, or a pair of sockets may be moved relatively by a bi-metallic member.
