Abstract: 434,094. Speed governors. SOC. ANON. SOLEX, 190, Avenue de Neuilly, Neuillysur-Seine, France. Nov. 20, 1933, No. 32282. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 18, 1934]. Application for addition to 403,797, [Group XXVII]. [Class 57] The parent Specification describes a carburetter in which the maximum speed of the engine is limited to a predetermined value, by using the suction existing in front of and beyond the throttle valve in combination to stop or restrict the supply of fuel to the jets. According to the present invention, the combined suctions are utilized to act on a piston or diaphragm to modify the position of the throttle valve. As shown in Fig. 1, the suctions are transmitted through orifices 5, 6 and a tube 2 to a chamber 3 and act upon a spring-controlled piston 17 which through a lever 18 controls the throttle valve 4, the opening of which is limited by an abutment 23 carried by an accelerator rod 22. The chamber 3 may contain an air valve 7 controlled by the axle of the valve 4 as described in the parent Specification. In modified constructions, two throttle valves are provided in the induction pipe, one being controlled by the combined suctions and the other manually, and the manually controlled valve may be arranged either in front of or behind the suction controlled valve, which may be under the influence of the combined suctions existing in front of the first valve, between the valves, and beyond the second valve.

Title: Method for the production of ethylene from a liquified natural gas
Inventor: BURNS WILLIAM DOUGLAS ALEXADER
IPC: C07C11/04
Filed: 1964-08-10
Abstract: Vaporized methane, and ethylene are obtained from liquefied natural gas containing methane and heavier hydrocarbons by fractionating in a first demethanizer to obtain vaporous methane overhead and a heavier hydrocarbon bottoms, cracking the latter to produce a gas mixture containing methane and ethylene, separating the methane in a second demethanizer and passing the liquefied natural gas before fractionation through a heat exchanger to condense reflux for the second demethanizer and subsequently through a heat exchanger to condense reflux for the first demethanizer. Liquefied natural gas from store 10 is pumped by line 11 through heat exchangers 12, 13, 14, 15, 16 and 17 to first demethanizer 20.  Vapour may be separated intermediately, e.g. in separator 18.  Methane is obtained overhead and partially condensed in heat exchanger 16, vapour being removed by line 29 and liquid being refluxed by line 28.  Bottoms may be split into ethane C2 hydrocarbons (line 32), C3 (line 33) and C4 (line 34) by fractionators 21 and 22 for separate cracking in cracking plant 35 or may be cracked without separation.  After cooling and drying the combined products are split into two streams in lines 40 and 41 for cooling with methane vapours and liquid respectively before being fed into second demethanizer 23.  Overhead is partially condensed in heat exchanger 12 to provide reflux.  The bottoms are further separated into ethylene (line 59), ethane/bottoms from fractionator 25) and C3 and higher hydrocarbons (bottoms from fractionator 24). <PICT:1011518/C4-C5/1>

Abstract: 1432684 Automatic control of course TOKYO KEIKI KK 9 July 1973 [10 July 1972]  32562/73 Headings G3N and G3R In a known marine autopilot system in which a course error signal is derived (at 1, 2) to produce a rudder order signal (from 3, 4) for controlling a servo loop including an amplifier 7 and relay-like device 8, the said device 8 is arranged to turn on at a value equal to its switching differential (hysteresis) so that it turns off when its input returns substantially to zero. It is shown that this produces a better control characteristic Fig. 5 (not shown) than the prior art system, Fig. 3 (not shown), wherein turn off occurs at an input above zero. Circuit details of elements 4-8 are given Fig. 2 (not shown). The turn off at zero feature of 8 is produced by selecting ratios for its components according to a given equation, some of which form a positive feedback circuit. The element 3 may have a P, a P.D or a P.D.I. characteristic and the device 8 switches a driver 9 comprising a relay, or a thyristor, triac or transistor circuit controlling an A.C. or D.C. or hydraulic  rudder motor 10. 11 and 6 provide rudder position feedback. The sensitivity of the system, i.e. the error necessary to turn on 8, is adjustable to match weather conditions by a potentiometer in a feedback circuit of amplifier 7.

Abstract: 837,460. Electrodialysis. PERMUTIT CO. Ltd. Oct. 17, 1958 [Oct. 18, 1957], No. 32630/57. Class 41. An electrodialytic cell is composed of circular membranes selectively permeable to ions of one or other sign and circular gaskets so arranged that they form a cylindrical stack in which the membranes and compartments between them alternate, the stack being surrounded by a cylindrical sleeve of insulating material which is in turn surrounded by a cylindrical metal sleeve resisting any lateral deformation of the stack and means being provided outside the membranes for exerting axial pressure on the stack to hold the membranes together. As shown (Fig. 1), a stack 1 of circular membranes and gaskets is bounded by an electrode 2 at each end lying in a recess in a circular plate 3 of electrically insulating material which in turn is in contact with a circular metal end-plate 4 that extends radially outwards, and through which there pass tightening bolts 6. Stack 1 is surrounded by insulating sleeve 7 which in turn is surrounded by cylindrical steel sleeve 8. In use, one liquid flows through every alternate compartment and a different liquid through the remaining compartments. Alternate gaskets 9 and 10 are shown in Figs. 2 and 3. Each gasket is made with arcuate ports 11 and 12 arranged in opposite pairs. All the ports 11 in the stack register with one another and with similar posts in the intervening membranes to form continuous passages for one liquid through the cell; and the ports 12 likewise register to form passages for the other liquid. In gaskets 9 passage forming inserts 13 replace the material of the gasket between the posts 11 and the central opening, and in the gaskets 10 similar inserts 14 connect the ports 12 with the central opening in the gasket. Next to each electrode 2 is an electrode compartment bounded circumferentially by a gasket having no inserts giving access to the central compartment for either of the two above liquids. Electrolyte solutions are led to and from these electrode compartments through passages (not shown) in plate 3.

Title: Process for preparation of tertiary aliphatic amines
IPC: B01J23/86
Filed: 1976-08-06
Abstract: Tertiary aliphatic methylamines of the formula I, which have 1 to 2 long-chain alkyl or alkenyl radicals having 8 to 24 C atoms, are prepared by reacting the corresponding alcohols and/or aldehydes with primary or secondary methylamines in the liquid phase under virtually pressure-free conditions. In this process, a hydrogen/amine mixture, where the amine accounts for 1 to 20% by volume, is circulated. The reaction is carried out in the presence of a cobalt chromite or copper chromite catalyst. The water of reaction is removed from the circulating gas. The resulting amines can be used as intermediates. <IMAGE>

Title: Automatically controlled weigh feeding apparatus
IPC: G05D7/06
Filed: 1973-07-10
Abstract: 1434383 Automatic control systems R J RICCIARDI A FERRARA and A A URBAN 10 July 1973 32882/73 Heading G3R The rate at which particulate material is discharged from a container 10 is controlled in response to the differentiated output of an electrical device 22 which continuously weighs the container. As shown, the device 22 is a variable transformer whose output is rectified before differentiation. The output of the differentiator is compared with a reference voltage for desired rate of flow (discharge) and the result used to control the speed of a motor 16 driving an auger discharging device 12. For this speed control, thyristors in a bridge supplying the motor are triggered at variable phase angle by a uni-junction transistor relaxation oscillator controlled in response to the difference between the comparator output and the signal from a D.C. tachogenerator Fig. 4 (not shown). The comparator Fig. 3 (not shown) comprises operational amplifiers and an RC circuit arranged so that the response to large errors is more rapid. The final stage comprises a further op. amp. and capacitor which maintains the output at the level existing when a relay contact is opened. This occurs when the output of weigher 22 reaches a pre-set low reference level, causing a second motor 38 to be energized to refill the container 10 from a storage container 34. Thus, refilling does not disturb the flowrate from 10. Refilling motor 38 is stopped when a pre-set high output from 22 is reached. The output of the comparator is limited by a Zener diode, and the differentiated signal is also supplied to a visual flow-rate indicator. The control circuitry 24 is illustrated in block diagram from Fig. 2 (not shown). In a modification Fig. 7 (not shown) the output of the differentiator is further differentiated; when the output of this exceeds a set value (due, e.g. to manual disturbance of the container) the relay contacts in the comparator are opened to maintain the output at the undisturbed level, as during filling.
