Title: Improvements in and relating to processes and apparatus for determining variations of dimensions
IPC: G01B13/06
Filed: 1933-06-21
Abstract: 402,008. Gauging-apparatus. SOC. ANON. DE CONSTRUCTION DE MATERIEL AUTOMOBILE S. A. C. M. A., 14, Rue Raynouard, Paris. June 21, 1933, No. 17656. Convention date, June 23, 1932. [Class 106 (ii).] Means for measuring a dimension in which the pressure of a flow of fluid through two orifices, the second of which is constituted by the clearance between the object to be measured and an orifice surrounding it, is used to influence a manometer which may cause the operation of a signal or control means of a machine. The chamber 1 is connected by a first and regulable orifice 2 with a supply 5 of fluid, air for instance, under a constant pressure determined by pipes 7<1>, 7<2> dipping into a tank of liquid kept at a constant height by an overflow 10. The chamber 1 is connected to a manometer 4<1>, 4<2> and by a pipe 12 to a tube 13 of circular or poly zonal cross section closed at the lower end 14 and provided with apertures 3, 31 at the ends of a diameter. The piece A the variations in the outer cross sections of which are to be determined is passed through the apertures and the reading on the manometer corresponds to the average of the cross sections of the piece A at entry and exit of the tube 13. In a modification the tube 13 is open ended and provided with diametrically opposite longitudinal slots 17 in the end through which slots a piece B is passed and the reading of the manometer corresponds to the mean longitudinal sections of the portion within the tube. In a further form the page 12 is connected to a vessel in which is a bobbin on which is wound a flexible thread which is passed through an orifice and wound on a second bobbin outside. By this means the mean section of the thread is measured. In a last form Fig. 5, each manometer consists of a branch 29a, 29b &c. immersed in a common open vessel 30 containing up to a suitable level a liquid which conducts electricity. The chambers 27a, 27b are connected to a common supply 28 and communicate with apparatus of the second form described above, that is with pipes 11 ending in open slotted ends through which threads 3 pass. If any of the threads are too small, or break, the liquid ascends in the branch of the corresponding manometer and comes into contact with an electrode 31a &c., closing a circuit to stop the machine. Specifications 326,674, [Class 106 (ii), Dynamometers &c.], 348,860, 367,700, and 388,265 are referred to.

Title: Process and apparatus for the selective hydrogenation of vegetable and animal unsaturated oils and fats
IPC: C11C3/12
Filed: 1956-06-11
Abstract: <PICT:0834817/III/1> In a process for hydrogenating unsaturated fats and fatty oils in which the mixture of oil and catalyst is circulated with hydrogen through a closed circuit including a reactor, the hydrogen is admitted on the pressure side of the circulating means, e.g. a pump, and does not exceed in amount 0.5% by weight of the oil/catalyst mixture.  A more uniform distribution of hydrogen in the fatty oil is achieved.  An apparatus comprises a reaction vessel 1, Fig. 1, provided with heating coil 17 and cooling coil 18, an outlet pipe at the base connected to a supply line 5 for the mixture of oil and nickel catalyst, a circulating pump 4, mixer 12, and pipe 2 admitting this mixture to the reaction vessel.  Hydrogen is admitted through a valved pipe 7, and is drawn off by pipe 9, by a pump 11 which passes the gas to the mixer 12 on the pressure side of the pump 4.  The hydrogen passes through a jet in the mixer 12 which disperses the gas in the oil/catalyst mixture.  Alternatively, blade wheels, baffles, or turbine wheels are used in the mixer.  The hydrogenated product is drawn off at pipe 13.  In an example, 10 kgs. of cottonseed oil and 10 g. of nickel catalyst are circulated at the rate of 10 kgs. per min. into the reactor which is maintained at 175 DEG  C.  Hydrogen is introduced into line 2 at the rate of 1 g. per minute, and after 2 hours above 40 g. of hydogen are absorbed.  The hardened fat produced has a m.p. 44 degrees and contains 30% saturated fatty acids, 68% oleic acid and under 1% of linolenic acid.

Title: Improvements in direct current electric motor control systems for cranes, hoists andthe like
IPC: B66C13/26
Filed: 1944-09-21
Abstract: 594,957. Control of D.C. motors. LAST, C. H., FERRY, H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 21, 1944, Nos. 18073/44 and 2988/45. [Class 38(iii)] In a direct current motor control system for cranes, hoists, and the like wherein the motor is of the series characteristic type and in which lowering is effected by connecting the field F between the supply-lines L1 and L2 in series with a potentiometer resistance R and connecting the motor armature A to sections of the resistance R, the motor driving small loads downwardly and acting as a generator with large loads, excessive braking-currents are prevented when the controller is returned to the " off " position when lowering heavy loads by limiting the reduction of potentiometer resistance when the motor is running at high speed. The system, as shown, has a manually-operated control and addiditional electromagnetically-operated contacts Cx and Cy are provided, the operating coil K of which is connected across one or more sections, 3 or 4 and 6, of the resistance R. On movement of the manual controller from the " off " position contacts C1, C2 and C3 close but no current passes through the contacts C1 and C2 since contacts Cx and Cy are open, however, sufficient current passes through the coil K to close its contacts almost instantaneously. Thereafter, the controller successively opens the contacts C1 and C2, closes contacts C4 and opens contacts C3, and so on. When the contacts C4 and C5 close the current in coil K falls to open the contacts Cx and Cy, if the controller is then moved to the position wherein the contacts C1 and C2 close, and if the motor-speed and voltage are high, the current in the coil K is insufficient to close the contacts Cx and Cy, which are not closed, to allow normal manual control, until the motor-speed falls. Contacts Cz may be placed in series with the coil K and are opened by the manual controller at the same time as contacts C4 are closed to provide definite de-energisation of the coil K at the appropriate moment when moving from the " off " position. In a modification of the invention the contacts Cx and Cy may have separate operating-coils. Alternatively, said coils may be separately supplied and energised when the controller moves from the " off " position, the energising current of the coils comprising a one-way-acting time-delay switch, which is opened on the higher speed notches of the controller to quickly deenergise the contactor coil, and when the controller is returned to the " off " position the switch closes at a pre-determined position of the controller, under the control of the time-delay device.
