Title: Improvements in and relating to hoists for cages ascending and descending between a fixed and a variable stop
IPC: B66B1/08
Filed: 1953-06-05
Abstract: 765,783. Winding and paying out apparatus. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. June 5, 1953 [June 19, 1952], No. 15539/53. Class 78 (5). A hoist with a cage raised and lowered between a fixed and variable arresting position is suspended by one or more load ropes and has a control rope guided over a tensioning pulley co-operating with an electric switching device of the motor lifting gear and attached at one end to one end of a switch lever mounted in the cage and at the other end to the same constructional part of the hoist as the end of the rope remote from the cage. As shown in Fig. 1, with reference to a gas-holder b with a roof a and variable level closure disc g, the lift cage i is suspended by load ropes h and has a control rope f, both ropes being wound on a drum k driven by a winch c or secured to the cage counterweight. The control rope f is anchored on a control lever m secured to the cage and passes over a pulley c on a pivoted arm, one end of which moves between on and off switches s controlling an electric motor. The movement of the cage can either be controlled manually by the lever m by setting it for down, up or stop and the cage is automatically stopped by an abutment p which moves the lever m to the stop position at the upper limit and by contacting the disc g which causes the load rope f to slacken and allows the pulley e to rise and move the switch lever to the stop position. If the disc rises and the lever m is set for lowering the pulley e rises further and initiates the ascent of the cage. If the lever m is set in the stop position the hoist can then only follow the upward movements of the cage.

Title: Improvements relating to rotary wing aircraft
Inventor: SISSINGH GERHARD JACOBUS
IPC: B64C1/00
Filed: 1949-06-10
Abstract: 682,509. Helicopters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 18, 1950. [June 10, 1949] No. 15565/49. Class 4. A stabilizing means for a rotary wing aircraft has one gyratory stabilizing system adapted to control the pitching motion and a second gyratory stabilizing system for controlling the rolling motion of the aircraft. The present invention comprises automatic stabilizing members similar to those described in Specification 675,657 except that the present arrangement provides stabilization when the moment of inertia of the aircraft about the rolling axis differs considerably from that about the pitching axis. Each stabilizing system comprises two pairs of bars mutually spaced at approximately 90 degrees and in one system one bar 11 of a pair is linked to a compensating lever 12, the other bar 13 of that pair being linked to an intermediate point on such lever. The lever 12 is connected by a link 14 to a rotary swash plate 15 mounted on an engine driven shaft which preferably rotates at a higher speed than the main rotor. The bars 16, 17 of the other pair are connected by a similar differential linkage 18, 19 to the member 15 at a point 90 degrees from the connection of the link 14. A rod 22, which lies in a plane containing the fore-and-aft axis of the aircraft or one parallel thereto connects the non-rotatable element 20 of the swash-plate to the cyclical pitch control mechanism of the rotor to effect control of the pitching moment of the aircraft. The upper stabilizing system is similar to that just described except that the linkage ratios in the differential linkages are different to those in the lower system. A rod 27, connected to the non-rotating element 26 of the upper swashplate 25 is connected to the rotor pitch changing mechansim to effect control of the rolling motion of the aircraft. The rods 22, 27 may be connected to the cyclical pitch control mechanism directly or by means of a compensating lever to give "stick free" or "stick fixed" stability as required and in the case when the speeds of the rotor and the shaft 10 are the same both non-rotary rings 20, 26 may be omitted, the rotary swash plates 15 and 25 being connected directly to the cyclical pitch control mechanism. The points of connection of the links 22 and 27 to the rings 20 and 26 may be displaced angularly from the positions shown in order that one gyratory system may assist the controlling effect of the other system and provision for trimming may be made by means of adjustable members in the links 22 and 27. In the case of multi-rotor helicopters, the rods 22 and 27 may effect collective instead of cyclical pitch change of the rotor blades.
