Title: Improvements in or relating to the feed supply means for use in conjunction with continuously operating automatic weighing machines
IPC: G01G13/24
Filed: 1928-11-24
Abstract: 325,595. Avery, Ltd., W. & T., and Gilbert, A. S. Nov. 24, 1928. Discharging-devices for endless-belt conveyers ; shoots.-A feed supply means for use between the discharge end of a conveyer and the weighing hopper of an automatic weighing machine comprises a bi-compartmented auxiliary hopper 3 wherein the discharge gates 3<a>, 3<b> are controlled by toggle linkages 13, 14 adapted to be broken for effecting the opening of the gates and wherein the auxiliary hopper is maintained in each of its filling positions by means of a lever 8 or 9 connected by links 6, 7 to the hopper, the levers 8, 9 co-operating with triggers 11<a>, 12a carried by counterweighted levers 11, 12 and being tripped when the weight of material fed into a compartment equals or exceeds a predetermined amount. The material, for example, coal, is carried by a conveyer 1 and is dropped into one compartment of the bi-compartmented auxiliary hopper 3 mounted on a pivot 4. When sufficient coal has entered the compartment to overcome the resistance of the weighted lever 12, the hopper rocks about its pivot 4 until arrested by the contact of a bracket 3<d> with a fixed stop 5<a>. The second compartment then receives the flow of coal from the conveyer. The rocking movement brings the extremity 14<a> of the toggle linkage 14 against a fixed stop 5b and breaks the toggle, thus opening the discharge gate 3<b> and permitting the coal to fall into the weigh hopper 2 of an automatic weighing machine. A similar operation then takes place in connection with the second compartment.

Title: Boundary layer control of flow separation and heat exchange
IPC: B64C23/06
Filed: 1969-07-09
Abstract: 1281899 Boundary layer control BATTELLE DEVELOPMENT CORP 9 July 1969 [9 July 1968] 34681/69 Heading F2R [Also in Divisions F1 and F4] A surface is provided with a plurality of elements defining concave regions of depth less than the boundary layer thickness of a fluid flowing over the surface, so that the fluid forms vortices which are amplified by further concave regions downstream of the first region so that the inception of flow separation is displaced. Thus a surface 30, such as an aerofoil, has a series of part-cylindrical elements 32, in sections 32a- 32c at angles to the direction of flow in a zigzag manner so that adjacent sections form vortices 20 of opposite sign. The vortices are amplified greatly by the concave valley following each element 32 and are attenuated only slightly by each succeeding element 34. The elements may be part-cylindrical, Fig. 3, or may have one of a number of longitudinal or lateral cross-sections, Figs. 7 and 8 (not shown), and may be arranged in individual chevrons 60, 70, Fig. 6, or continuous zig-zags 62, 72 or undulations 74. Instead of having raised elements on a basic surface there may be depressions (28), Fig. 9 (not shown), in a surface, containing wedge-shaped plates (55). Arrays of elements may be located where necessary on an aircraft, Fig. 10, such as at engine inlets or fairings, possibly including arrays (100), Fig. 12B (not shown), on slotted flaps (95) which are only exposed when the flap is extended. So as not to provide drag at high speeds the elements may be retractable or inflatable. Alternatively the elements may be formed on a rotor or turbine blade, Fig. 13 (not shown), or on the fins of a heat exchanger, Fig. 15 (not shown), or at bends or irregularities in flow passages.

Title: Improvements in or relating to Apparatus for Controlling a Variable.
Inventor: HENDRICK RUSSEL C
IPC: G05D1/06
Filed: 1968-07-22
Abstract: 1,171,044. Automatic control of aircraft. HONEYWELL Inc. July 22, 1968 [July 28, 1967], No. 34782/68. Heading G3R. Apparatus for controlling the altitude of an aircraft includes a control signal selecting circuit 71 whereby altitude is changed to a desired altitude under the control of whichever of the control signals (altitude value or altitude rate of change) produces the least rapid change of altitude towards the derived altitude, thereby obviating an initial drastic control effect. Switches 45, 62, 63, 67, the signal selection circuit 71 and the switch arm 72 are a mechanical representation of the electrically operating arrangement of Fig. 2, showing the possibility of selecting the "altitude" and/or "altitude rate" modes. When both modes have been selected, circuit 71 operates to provide, alternatively proportional integral control of servosystem 10 (controlling elevators) from the altitude rate error signal, or proportional and integral control of servosystem 10 from the altitude error signal, via lines 29 and 79. A typical pitch attitude control system has these extra control signals fed in at a summing arrangement 24 via line 29 and at integrator 14 via line 79. The signal selection circuit 71 includes two high gain inserting amplifiers 134, 156, Fig. 2, taking their inputs from lines 107, 130, carrying the altitude rate and altitude control signals respectively. Control terminals A-E can be selectively energized by the mode selector or switching circuit of Fig. 3. When both control signals are selected by de-energizing field effect transistors 135, 157, by control voltages at terminals A and B, the combination of diodes 139, 140, 166, 167, ensures that the more negative (or less positive) signal always appears at junction 144 and the more positive at junction 146. Consequently by making FET 151 conductive (by applying the appropriate voltage at terminal C) but not FET 141, it ensures that the more negative of the two signals is always supplied to line 174, and by making FET 141 conductive (by a voltage on terminal D) but not FET 151, the more positive of these will always be supplied to live 174. Manually operable switches 214, 219, Fig. 3, operate switch drives 201-204 directly or indirectly to apply control voltages at terminals A-E, giving different combinations of altitude mode selected, (by closing switch 219), altitude rate made selected, (by closing switch 214), and positive or negative sense for the altitude rate, (by control knob 41, Fig. 2, and reflected in the polarity of the voltage on line 237 from the altitude rate reference 53, Fig. 1), see table of Fig. 4, (not shown). Closing of switch 219 results in positive pulse outputs from altitude engage foder 215, Fig. 3, of gradually increasing width until a continuous signal is applied via switch driver 202 to control terminal B, thereby avoiding sudden response.

Inventor: ZOLCH LOTHAR
IPC: C07F9/40
Filed: 1959-10-19
Abstract: b :b :b -Trichloro-a -oxyethylphosphonic acid dimethyl ester is purified by recrystallising the crude ester from water which may contain a monohydric or polyhydric water-soluble alcohol or a surface active agent, e.g. an alkali metal salt of a long chain paraffin sulphonic acid.  Specified alcohols are methanol, ethanol, propanol, ethylene glycol, a polyglycol and hexanetriol. The purification process may be effected by dissolving the crude ester (which may suitably be obtained by reacting phosphorus trichloride methanol and chloral e.g. as disclosed in Specification 861,780) in water with stirring and slight heating and then cooling to 0 DEG -5 DEG c. until the ester crystallises out. Alternatively, the crude ester may be heated to form a melt which is then dissolved in water and the solution cooled until crystallisation occurs.  If desired the solution may be treated with active carbon before cooling so as to remove any colouration and may be inoculated with crystals of previously purified ester to aid in the crystallisation.  Examples are given. Specification 731,506 also is referred to.
