Abstract: 891,783. Steering trailers. AUTOSET (PRODUCTION) Ltd. Oct. 13, 1958 [July 13, 1957], No. 22258/57. Class 79(5). In a vehicle having at least one pair of steerable castors 6, Fig. 1 interconnected as by a track rod 17 for rotation in unison, the steering is actuated by pivotal movement of a turntable 25 from which the castors may be disconnected. Steering movement of the turntable 25 by a tow bar 28 is transmitted to the track rod 17 through a drag link 23 and bell crank 21. The steering may be disconnected by removing pins 15 on the ends of the track rod 17 which falls on to hooked supports 17a while plates 12 pivoted on the steering arms 10 swing downwards clear of the track rod 17 so that the units 6 are free to castor. The pins 15 may then be used to insert through aligned holes in the turntable 25 and frame 9 to lock the towbar 28 in the straight ahead position. The wheels 6 may be braked and the castoring locked through links 18a, Fig. 2, described in Specification 884,584 which are actuated by pivoting the tow bar 28 about a transverse rod 27 or by backwards movement of the transverse rod in slots 26a against the loading of springs 29 when the trailer is over-running the tow vehicle. Actuation of the braking or locking means is obtained through a cam 30 on the tow bar 28, bell crank 31 and operating rod 35. The brakes may be held out of operation when the tow bar 28 is stowed in the vertical position as by insertion of a locking pin through a registering hole 44 in the bell crank 31.

Abstract: 1501195 Removal of CO 2  and/or H 2 S from gaseous mixture G GIAMMARCO and P GIAMMARCO 22 May 1975 [28 May 1974] 22382/75 Heading C1A An acidic gas comprising CO 2  and/or H 2 S is removed from a gaseous mixture in an absorption stage, by contacting with an aqueous solution of an alkali metal carbonate and added amino acid, and a regeneration stage where the acidic gas is expelled from the absorbing solution, where the absorption stage is operated in two subsequent zones, at 90-130 C. to remove a major proportion by volume of CO 2  and/or HIS and 50-85 C. to remove the remaining minor proportion by volume of CO 2  and/or HIS respectively. The amino acid concentration in the first zone, preferably 30-50 gl.<SP>-1</SP>, may be lower or equal to that in the second zone, and the preferred amino acid is glycine. The regeneration stage may comprise two zones. Compounds of arsenic and/or vanadium may be added to the absorbing solution as corrosion inhibitors. In a first embodiment, shown in the drawing, an absorbing solution (typically containing 150-250 gl.<SP>-1</SP> of the CO 3  expressed as K 2 O and 100-150 gl.<SP>-1</SP> glycine) at 110-115 C. is pumped from the bottom of regeneration column R by a pump P 2  and conveyed through heat exchanger Sc and cooler F to the top of the absorption column A. The solution descends in the upper zone A 2  in countercurrent with the gaseous mixture already partially purified in the lower zone A 1 , and the exhausted solution collecting at partition C is discharged through pipe T and preheated in heat exchanger Sc, before being delivered to the top of the lower regeneration zone R 2  where it is heated and regenerated by steam evolving from the bottom of R. A second solution (typically containing 200-250 gl.<SP>-1</SP> K 2 CO 3  and 50 gl.<SP>-1</SP> glycine) is pumped by P 1  from partition D of R at 108-110 C. to the top of A 1 . The exhausted solution collects at the bottom of A and is conveyed to zone R 1  for regeneration. To carry out a second embodiment, where a single absorbing solution at low concentration of amino acid (typically 30-50 gl.<SP>-1</SP> glycine) is used in both absorption zones, the pipe T and the heat exchanger Sc are eliminated from the drawing. A third embodiment uses a single regeneration zone, and the regenerated solution is split into a minor and a major fraction by volume. The minor fraction is cooled to 50-85 C. and is supplied to the top of A, and the remainder is passed to an intermediate section of A.

Title: Method of extracting pection and pection produced thereby
IPC: C08B37/00
Filed: 1930-07-25
Abstract: Pectin is extracted from fruits, vegetables and parts of plants by means of a solution having a pH value of less than 1,9. The peel of fruit such as citrus fruit, obtained, for example, from a process for expressing the juice or oil, is ground and heated to destroy the enzyme pectinase as described in Specification 239,635, [Class 121, Starch &c.].  Two or three volumes of water are added, together with sufficient acid, for example hydrochloric, nitric, sulphuric, sulphurous, phosphoric, oxalic, tartaric or citric acids to give a solution having a pH value of between 1,2 and 1,9.  The extraction mixture is then agitated, preferably at 50 DEG  C. to 70 DEG  C. for about 30 minutes, after which the coarse pulp particles may be separated, prior to clarification of the extract, by means of screens, hydraulic presses or filters.  If a siliceous filter-aid having a high rate of flow, such as calcined diatomaceous material containing silica in the crystalline form of crystobalite, is used for clarification of the extract by filtration under pressure, the pH value is adjusted to a value between 1,2 and 1,6. The clear extract is then either concentrated to form a liquid product, or partly concentrated and the pectin precipitated, for example with alcohol, purified, dried and ground.  During these final stages of the process the acidity of the extract may be neutralized by a base or the salt of a strong base and a weak acid.  The pectin product is suitable for use in making jams and jellies and is stated to have an inherently long setting time, while its aqueous dispersions have a relatively high viscosity and low surface tension.

Patent GB-1578936-A (GB)
Title: Method of operating a turbo-compressor
IPC: F04D27/02
Filed: 1977-05-27
Abstract: In this method, which involves continuous measurement of the throughput and the delivery pressure, surging is prevented by ensuring, by opening blow-off valves, that the compressor does not fall below a minimum throughput which depends on the delivery pressure. Said opening takes place after a blow-off line parallel to the surge limit has been crossed. To this end, firstly, electrical signals which correspond to the throughput and the delivery pressure are taken, and in a comparator their difference is formed which is destined for a controller which acts on the blow-off valves. If this difference, owing to the compressor having crossed the blow-off line, is negative by a defined minimum value, it is amplified by a non-linear transmission element upstream of the controller, so that the effect of the controller is also amplified. As a result, the blow-off valves are opened more strongly, so that the operating point (BP) of the compressor is moved back into the permitted range. <IMAGE>

July 28, 1930, No. 22690. Convention date, July 27, 1929. [Class 38 (iv).] A gaseous discharge device such as a lightning arrester or potential regulator is provided with h electrodes coated with a mixture of an alkali metal or an alkaline-earth metal with its oxide or another compound, the mixture having a lower work function than that of the metal alone. A mixture of the metal and its oxide may be obtained from a compound of the metal such as the azide, oxide, hydroxide, or carbonate by partial reduction. If potassium hydroxide is used it is dissolved in water and the electrode is coated with the solution and then dried. The electrodes are then mounted in the bulb which is evacuated and heated to drive out occluded gases and vapours. The temperature of the electrodes is then raised to about 800‹ which reduces the hydroxide to potassium oxide and metallic potassium. The electrodes may be in the form of hollow iron cylinders 4 which can be heated by a high-frequency inductive field to drive out occluded gases during the process of manufacture. The tube is exhausted through a tube 5 and then filled with gas such as a mixture of helium and neon.
