Title: Improvements in or relating to ground-based flight training or simulating apparatus
Inventor: CUTLER ALBERT ERNEST
IPC: G09B9/28
Filed: 1962-07-08
Abstract: 958,325. Electric correspondence control systems. COMMUNICATIONS PATENTS Ltd. June 8,1962, No. 22241/62. Heading G1N. [Also in Division B7] In a grounded aircraft trainer having a control column connected to force generators actuated by a displacement pick-off whereby the operator at the control column obtains the feel of the forces he is controlling, two force generators are utilized, one producing the low frequency components and the other the high frequency components of the required force. As shown (Fig. 3), movement of the control column is sensed by a potentiometric pick-off which feeds an electrical signal to a flight simulator computer where it is modified in accordance with the aerodynamic performance of the simulated aircraft, and the nominal existing conditions of flight. The modified signal is compared with a signal from a force pick-off measuring the output from a main force generator consisting of a hydraulic ram, and any difference, determined by a summing unit, is amplified at A1 to actuate the main force generator, and also fed to an auxiliary force generator with a high frequency response, comprising a low inertia motor M and gearbox, through a second amplifier A2. The two force generators are mechanically coupled to the control column through a mixing linkage. The gain-frequency characteristic of amplifier A2 is adjusted to give low output at low frequencies, or a high pass filter is added in front of amplifier A2 and a low pass filter in front of amplifier A1 The input to amplifier A2 is augmented by a displacement signal to provide for centering of the two force generators when their outputs are otherwise balanced.

Title: Improvements in or relating to strap securing devices
IPC: B65D63/14
Filed: 1955-08-08
Abstract: 780,459. Tensioning straps. EASTERN ROTOCRAFT CORPORATION. Aug. 8, 1955 [Aug. 16, 1954], No. 22763/55. Class 45. [Also in Groups VII and XXV] A strap securing device comprises parallel rods 15 spaced slightly greater than the width of the strap, two parallel terminal bars 19, 22 supported between the rods near one end of the device, the ends of one of the bars 19 being fixedly attached to the rods, the ends of the other bar 22 being movably supported on the rods, each of the rods having a longitudinally extending slot 24 therein for the support of the movable bar, a strap assembly 10 having one end anchored to the fixedly attached bar. As shown, a single piece of metal is bent to form the parallel rods 15 and an end rod 16 which is offset from the side rods 15 and connected to them by posts 17. The free ends 18 of the rods 15 are flattened and are riveted to bar 19. The slots 24 are formed in the ends 18 and the second bar 22 has extensions for engaging the slots 24, the extensions being elongated to prevent rotation of the bar 22 with respect to the rods 15. The free end of the strap is passed between the bars 19, 22 and the strap can then be tensioned by swinging the device through 180 degrees. This causes the portion of the strap between the two bars to be gripped since the bar 22 slides in its slot. The device is secured to the strap to maintain the tension in the strap by means of a retention device 25 which is pivotally mounted on one of the posts 17 and which has a rod 26 which can be passed underneath the strap. In a modification the positions of the bars 19 and 22 are reversed and the end of the frame is not offset. The retention device 25 is omitted but in the place of it a sleeve is provided which is slidably mounted on the rods 15 and over the fixed end of the strap. The device can be used with two separate straps instead of a single strap. In such a case each strap is provided with an anchoring hook.

Filed: 1965-05-28
Abstract: N,N1 - Disubstituted - 4,41 - bipyridylium salts are prepared by interacting a pyridine with a solution of an alkali metal or alkaline earth metal in a substantially anhydrous liquid medium containing ammonia to form a metal-pyridine interaction product, interacting said product with an organic compound containing only one reactive halogen atom per molecule to form an N,N1 - disubstituted - 1,11,4,41 - tetrahydro-4,41-bipyridyl and thereafter converting said bipyridyl product to the N,N1-di-substituted -4,41-bipyridylium salt.  The metal solution may contain an inert organic diluent in addition to the ammonia and it is preferred that the conversion of the last step of the above process is effected by an organic oxidizing agent which is a hydrogen acceptor and has a redox potential more positive than - 1.48 volts with respect to the standard calomel electrode.

Abstract: 709,951. Fluid-pressure servomotors; valves. MITCHELL ENGINEERING, Ltd. Sept. 26, 1952 [Oct. 2, 1951], No. 22941/51. Class 135 A method of regulating the level of material in the drum 1 of a grinding mill utilizes the pressure in a gas conduit 14 discharging through a vertically elongated orifice 13 into the drum, the pressure being varied by the obstruction of the orifice by the material in the mill. The gas is fed through a restriction 17, and the modulated pressure is transmitted through a conduit 20 to a differential pressure regulator 24 which is subject also, through a conduit 25, to the pressure above the material in the drum, and is capable of applying proportional and differential control to a servo-mechanism (not shown) controlling the supply of material to the mill. A valve 21 is operated periodically by a toggle mechanism 34 to disconnect the conduit 20 from the regulator 24 and connect it instead with a gas supply 22 to blow through the orifice 13 to keep it clear. The toggle mechanism 34 is operated by pressure in a conduit 35 connected to a vessel 33 and to a toggle mechanism 36 actuating a valve 30 which allows pressure air to flow from a supply 28, through a conduit 31 with a restriction 32, to the vessel 33 until the pressure is sufficient to operate first, the toggle 34 and then the toggle 36, causing the valve 30 to connect the vessel 33 through a non-return valve 39 to a vent 38. In a modification the valve 21 is operated by solenoids controlled by a time switch. According to the Provisional Specification a number of orifices 13 at different heights may be provided to enable control to be effected at different datum levels.
