Title: Improvements in the method of absorbing gases and gaseous acids
IPC: B01D3/18
Filed: 1920-04-27
Abstract: 142,477. Nauerz, G. April 30, 1919, [Convention date]. Column-stills and rectifiers.-The Specification as open to inspection under Sect. 91 (3) (a) describes a process wherein a liquid, containing lighter volatile products not mixable therewith, is brought into intimate contact with a gas, allowing almost total recuperation of the said volatile products. The apparatus comprises a tower formed of a series of superposed dish-like elements c, c', c<2> in which the liquid is maintained at a constant level by overflow pipes m, n, o and in which the gas flows from one element to the next above it through pipes i each surrounded by a perforated bell h. The degree of absorption of the gas is regulated by using sets of interchangeable bells, the orifices j of which are arranged at different heights for different sets of bells. Liquid is supplied through a connexion v and flows through the apparatus in an opposite direction to that of the gas which is introduced through an inlet r and leaves through an outlet u. The elements c, c<1>, c<2> are heated by the condensation of the gas, thus producing a distillation of the volatile products which may be condensed and collected in one of the upper compartments of the apparatus, or, if the distillation is extended to the last compartment, the volatile products will be condensed and collected externally. The description of the process referred to above does not appear in the Specification as accepted.

Title: Optical testing device
IPC: G01B11/00
Filed: 1953-04-30
Abstract: 726,012. Optical apparatus. BENDIX AVIATION CORPORATION. April 30, 1953 [July 2, 1952], No. 12001/53. Class 97 (1). A device for determining the relative displacement between a movable controlled member and a movable controlling member comprises means for mounting the members, a light source mounted for movement with one of said members, a reflector controlled by the other member and reflecting a beam from the source on to a scale movable with said one member to determine the difference in position between the members, optical means being provided to extend the light path to magnify the displacement of the beam on the scale. The device is described as applied to the testing of synchro 40, Fig. 1, against a standard synchro 38 to which it is connected " back-to-back " so that a rotation of the rotor of the standard 38 should be accompanied by an equal rotation of the synchro 40. To test this correspondence the synchros 38 and 40 are mounted respectively in members 35 and 36 and a mirror 70 is fixed to the rotor of the synchro 40. Rotatably surrounding the member 35 is a disc 46, held in any desired angular position by a detent 50, Fig. 2, and carrying a lamp 58, lens 60 and mirror 62 directing a beam of light on to the mirror 70 when it is reflected successively by mirror 64 and 63, fixed to the disc 46, finally reaching a scale 68. An arm 53, secured to the rotor 42 of the synchro 38 is held between members 51, 52 fixed to the disc 46 so that as the latter is rotated, the rotor 42 is moved relative to the casing of the synchro 38, which is fixed in the member 35, and causes corresponding rotation of the rotor 44 of synchro 40. Any lack of correspondence between the rotations of the two rotors is shown by a displacement of the light spot on the scale 68.

Title: Improvements in ploughs
IPC: A01B3/30
Filed: 1927-05-04
Abstract: 271,441. Bec, P. C. May 19, 1926, [Convention date]. Turn-wrest implements; adjusting and lifting parts; wheels, arrangement of. - A turn-wrest plough in which the raising and reversal of the mouldboards are effected by the tractive effort, has a lever which initiates the raising and controls a clutching device for transmission mechanism which rotates the mouldboards. The beam 8, Fig. 2, is pivoted at 7 to members 5 carried by a frame 3 mounted on the front axle, and is acted on by springs 10; the depth of working is adjusted by means comprising a screw 38, nut 35 on a rod 36, and abutments 41. The members 5 are connected by a rod 43 to a socket 18, Fig. 2A, pivoted at 20 to the rear end of the beam, and carrying a wheel 15. The beam and mouldboards 13, 14 are lifted by raising a lever 26 so as to bring a rack 25 into engagement with a lantern wheel 28 keyed on the front axle. Towards the end of its movement, the lever 26 actuates a lever 75 to lift a roller 70 out of a notch in a pawl-carrying disc 60 loosely mounted on the front axle, thus allowing a spring 65 to move the pawl into engagement with a ratchet wheel 66 fast on the axle. The disc 60 is thus rotated and through chain and spur gearing drives a shaft 86. Cam discs mounted on the shaft 86 operate through pawls to clutch one or other of a pair of bevel wheels to the shaft; these bevel wheels mesh with another bevel wheel fast on a frame carrying the mouldboards, so that the frame is turned through 180‹ in alternately opposite directions. Stop mechanism to limit the extent of rotation comprises pairs of larger and smaller stop members 105, 106 carried by members 104<1>, 104<2>. Fig. 5, co-operating with slideways in a member 102 fast with the mouldboard frame, screw-and-nut means being provided for adjusting the members 104<1>, 104<2>. As the bar 43 moves forward during the raising of the beam, a member 130 acts on a lever 112 to disengage its arm 114 from the smaller stop 106; the subsequent rotation of the mouldboard frame ceases when the larger stop of the other pair contacts with the lever arm 114.
