Patent GB-580643-A (GB)
Title: Improvements in or relating to the separation and concentration of diolefins
IPC: C07C7/10
Filed: 1943-05-31
Abstract: Diolefins are separated from hydrocarbon mixtures by liquefying, maintaining the mixture as a continuous liquid phase, dispersing through it a cuprous salt solution as discontinuous phase, separating the cuprous salt solution, heating and recovering absorbed diolefins. The effect of temperature and of dissolved butadiene on the viscosity of a 3.8N copper, 3.4N cuprous solution of ammoniacal cuprous acetate is illustrated. The use of liquid C4 hydrocarbons as the continuous phase avoids the difficulties inherent in the use of the high viscosity copper solutions.  Comparative figures are given for liquid phase extraction in counter-current in a packed tower, using ammoniacal cuprous acetate, 2.47N cuprous ion, at 10-20 DEG  F. as continuous phase in one case, and liquid C4 hydrocarbons as continuous phase in the other, 2.7N cuprous solution being continuously passed therethrough and the extraction effected at 10-34 DEG  F., liquid hydrocarbons being continuously added to and withdrawn from the tower.  Alternatively, turbine mixers may be used to contact the phases.

Title: Electromagnet control circuit
Inventor: PETIT PIERRE LEON
IPC: G05F7/00
Filed: 1966-03-02
Abstract: 1,095,603. Selective punching. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 2, 1966 [March 11, 1965], No. 9060/66. Heading B4B. [Also in Divisions B6 and H3] In a device such as a punch the current in the operating coil rises until the armature moves towards the core whereupon it starts to decrease (Fig. 2, not shown). If the armature rebounds an abrupt change to an increasing current occurs (at N) and this is used to interrupt the coil current so that armature then returns to its rest position without further rebounds. In Fig. 5, the application of a pulse at A causes T3 to be rendered conducting and the load L to be energized. The current is sensed by a resistor r1 and differentiated by C3, r2. When the rebound causes the above-mentioned abrupt change to occur the differentiator causes the conduction conditions of T4 and T5 to changeover and a pulse is applied via T6, T7 and C4 to cause T3 to cut off again. A further feedback circuit from T2 via C2 makes the circuit of T1 and T2 monostable so that T3 is cut off even if the feedback through C4 is not effective. Fig. 6 (not shown) illustrates a plurality of parallel circuits (3) for a bank of card punches each of which circuits is controlled by an AND gate (G) having a " select " input (A) a driving input from a common monostable circuit (2) and a feedback input (5) generated from the previously mentioned abrupt change. This input is derived from a monostable circuit (T12, T13) driven via a 4-stage circuit from the differentiator.

Title: Improvements relating to photographic cameras
Inventor: GRATTON JOHN STEUART
IPC: G03B37/02
Filed: 1954-03-29
Abstract: 784,399. Photographic cameras. VINTEN, Ltd., W. March 29, 1955 [March 29, 1954], No. 9165/54. Class 98(1) Aerial survey photographs are taken with a panoramic type of camera which is continuously rotated at a uniform speed and takes a succession of photographs as, but not necessarily every time, it passes through a selected arc. The film 10 is thus only fed past the slit 9 at intervals separated by a whole number of revolutions of the camera which, as shown, includes mirror objective 2, casing 7, and supply and take-up spools 11. and 12, the whole being rotated on shafts 5 and 6. Preferably the film drive is operated by a sun and planet gear 20 and 21, a brake band 23 being applied to the sun wheel to stop its rotation,. The continued rotation of the camera turns planet wheel 21 and feeds the film until band 23 releases wheel 20 which then rotates in synchronism with the camera until the next exposure., The back of the film 10 may be arched by barrel-shaped sprocket 15 and film guides (not shown) may be similarly curved. When the slit 9 is sufficiently wide the film may be curved in a perpendicular direction either by the co-operation of the film guides and sprocket 15 or by the film guides alone, the sprocket being located elsewhere. The take-up spool 12 and, if desired, the supply spool 11 and film loop and tension mechanism (not shown) are driven from the shaft 22. The rotation of the camera is stated to have a gyroscopic stabilizing effect on the aircraft, the axis of rotation of the camera being in the direction of flight. The plane mirror 3 may be omitted and the film fed transversely across tube 4 behind a centrally located slit. Alternatively, the plane mirror 3 may be normal to the optical axis and the slit provided at the centre of mirror 2. The mirror system, including corrector lens 1, may be replaced by a lens system.

Filed: 1927-04-04
Abstract: 269,881. Akt.-Ges. Brown, Boveri, et Cie. April 22, 1926, [Convention date]. Regulating.-In a turbine comprising two sections a, b arranged so that their axial thrusts balance each other, and a duplex balanced section c, irregularities in the pressure drop arising from dirty blading or other causes may disturb the balancing and cause excessive thrust on the collar thrust bearing d. This is avoided by communicating the actual pressures p', p<2>, p<3> on both sides of the turbines a, b with spaces I, II, III formed by a flat diaphragm f and a tubular diaphragm e, designed so that when the pressure drop is normal the sum of the products of the surfaces on one side of the diaphragm f and the pressures acting thereon is equal to the product of the surface area on the other side and the pressure acting thereon. If one of the pressures p', p<2>, p<3> varies, the diaphragm system is displaced and actuates through levers h a slide-valve i controlling the outlet from the oilrelay system actuating the regulating valves of the turbine, which are thereby closed to a greater or smaller extent according to the displacement of the diaphragm. Two springs n tend to stabilize the diaphragm f, which may be adapted to the pressure conditions by varying the size of the mounts o, p. The diaphragm spaces are filled with water, and a flexible tube g strengthened by an inner wire helix is provided as a water-seal. The tubular diaphragm e may be strengthened by an outer wire helix. To make the device operative only over a certain range, the outflow edges k, d of the valve i are provided with a lap, the sleeve q being adjustable. Specification 237,209 is referred to.
