Abstract: 1527151 Crystallization point determination ANTAR PETROLES DE L'ATLANTIQUE 19 March 1976 [21 March 1975] 11168/76 Addition to 1488131 Heading G1B A method for the continuous automatic analysis of the crystallization temperature of a liquid substance for which an approximate crystallization temperature is known comprises passing the substance through a measuring circuit at a-constant flow-rate, a temperature therein being maintained at a value sufficiently below the approximate crystallization point to permit the substance to undergo cooling below its actual crystallization temperature, heating means being provided along the flow-path of the liquid substance in the circuit, maintaining the substance in the course of cooling in contact with an isomorphous crystalline material, automatically turning on and off said heating means at two characteristic temperatures respectively, which temperatures are detected by measuring the pressure difference of the substance at the inlet and outlet of the measuring circuit, variations in the pressure drop being effected as a function of temperature, the values of the pressure drop thus measured being utilized as control data for turning on and off the heating means when the temperature at the outlet reaches one of its two characteristic values, the first corresponding to the crystallization temperature level, whilst the other corresponds to a temperature sufficiently above the approximate crystallization temperature to permit crystalline material formed by crystallization of the said substance to be melted, and continuously recording the temperature of the substance at the outlet of the circuit, which constitutes a value representing the crystallization temperature of the substance. The substance is suitably an aromatic hydrocarbon. The method may be carried out in the apparatus shown in Fig. 2 in which the liquid substance is passed at a constant rate through the capillary tube 1. Tube 1 passes into a measuring well 2 and thence through the fluid-tight chamber 4 which contains an isomorphous crystalline material 5. The tube 1 is, with chamber 4, provided with an aperture so that the liquid substances to be analyzed can contact material 5. The apparatus is provided with a pressure-sensing means 11 and a thermosensitive element 15. Tube 1, which behaves as a heating resistance, is connected with an electrical supply 12.

Title: An improved method of and apparatus for the automatic weighing of loose or like material in portions of equal weight
IPC: G01G13/00
Filed: 1947-04-29
Abstract: 654,056. Weighing apparatus. POPOVA, S. April 29, 1947, No. 11422. Convention date, Dec. 12, 1940. [Class 143] In an automatic feed weigher of the kind in which material is delivered in a stream to weight a pan through a hopper having a normally open discharge gate which, after a predetermined weight of material has passed to the weigh pan, is closed so that the hopper temporarily collects the stream of material therein while the pan is being emptied; an additional material supplying means is provided to increase the rate of accumulation of material in the hopper during its closed periods. A motor 4 continuously drives a conveyer 7 which delivers material from a hopper 8 onto a scale pan 2 until the weigh beam 1 touches a contact 11 so closing an electrical circuit which energizes a solenoid 12 which, by attracting a member 13, releases catches 15, 16 and allows the gate 17 to shut under the action of a spring 18. Upward movement of the member 13 also releases a spring loaded plunger 19 which allows a member 21 to pivot and couple a constantly rotating annulus 22b to a freely rotatable pulley 22a which is operatively connected, by a crank 23 and rod 24, to a plate 14 carrying a pan emptying brush 3 and the member 13. This member, on the return stroke of the plate 14, engages catches 15, 16, opens the discharge gate and allows the material collected thereon to be dumped onto the scale pan, and also replaces the plunger 19 which re-engages the member 21 so disengaging the annulus 22b and pulley 22a. The pulley 22a drives an additional conveyer 37 which discharges a hopper 38 into the hopper 9 when the gate is closed so increasing the quantity of material available for dumping when the gate is re-opened. In a modification the additional supply of material is effected by either increasing the speed of the conveyer 7, or dumping measured volumes of material into the hopper 9, during the periods when the gate is closed.

Title: Hydraulically operated apparatus for charging workpieces
IPC: B25J5/02
Filed: 1973-03-09
Abstract: 1381692 Forging manipulators VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE AG 9 March 1973 [6 April 1972] 11515/73 Heading B3H [Also in Division F4]  A forging manipulator has a pivoted jaw carrier 2 provided with jaws 4 at one end operated by a double-acting hydraulic actuator 5 whose jaw closing chamber 9 is hydraulically connected to the chamber 7 of a piston cylinder device 6 responsive to tilting of the carrier. Thus the gripping force of the jaws 4 is increased in dependence on the weight of the workpiece 12. The hydraulic connection is effected by a conduit 18 provided with shut-off valves 10, 11 to isolate either or both the jaw actuator 5 and the device 6. A multiway valve 14 controls hydraulic flow from a high rate low pressure pump 28a and a low rate high pressure pump 28b to the hydraulic system. A pressure limiting valve 20 determines the initial gripping force of the jaws when the valve 11 is open, the valve 10 is closed and the multiway valve 14 is in the jaw closing position. After a workpiece has been gripped the valve 14 is returned to its neutral position and valve 10 is opened. The jaw carrier is raised by a hoist (not shown), and once the workpiece is not supported a tilting torque about the carrier pivot 3 causes the chamber 7 of the device to be pressurized in dependence on the workpiece weight and the pressure is transmitted to the chamber 9 of the jaw actuator to increase the gripping force. Mechanical limit switches (24)-(27), Fig. 4 (not shown), control the movement of the multiway valve 14 in response to uncontrolled tilting of the carrier to increase or decrease the pressure in the piston-cylinder device 6. The jaw carrier is rotatably mounted and driven through gearing (35), (36), Fig. 4 (not shown).

Title: Analyzer for determination of double bonds
IPC: G01N31/00
Filed: 1974-03-16
Abstract: 1434166 Photo-electric determination of double bonds INST KHIM FIZ AKAD NAUK SSSR 16 March 1974 11767/74 Headiog G1A To determine the number of double bonds in a chemical sample it is reacted with an ozone/oxygen or an ozone/air mixture and the amount of ozone absorbed, which is a measure of the double bonds, is determined by an ultraviolet measurement of the gas mixture after reaction with the sample. In Fig. 1 oxygen from container 2 is passed via valves 3, 4 and flowmeter 5 to a discharge apparatus 7 where it is partially converted to ozone. The resulting mixture passes through vessel 13 into which the sample can be introduced at 15, and thence to a measuring cell 17 where the ozone concentration is measured by U.V. source 19 and detector 24. The detector output is amplified at 25 for display at 34, and passes also to an integrating system 35. When the sample is introduced into vessel 13 there is an almost total absorption of ozone in the vessel at first, followed by a return to substantially no ozone absorption when the double bonds have all been broken. As a result the detector 24 produces an output as in Fig. 6, where the area under the curve represents the number of double bonds. This curve is recorded at 36, Fig. 1, by a recording potentiometer, Fig. 3, (not shown), which also drives a voltage to pulse frequency converter 37; the converter output can be integrated by digital counter 39 when switch 53 is as shown. In the other switch position the counter receives pulses from a discriminator 38 which emits pulses as long as its input is above a given level, thus allowing the time width of the curve of Fig. 6 to be measured. The base line of the curve can be adjusted by optical attenuator 20 in Fig. 1, or by adjustment of the ozone producing discharge, or by adjustment of the electric circuitry. Calibration with a known sample is needed. In another embodiment, Figs. 4, 5, (not shown), a further detector monitors the U.V. source, and the two detector outputs are differentially amplified before passage to the integrating system.
