Abstract: 1,272,968. Rolling mill. MASCHINENFABRIK SACK G.m.b.H. 28 July, 1969 [14 Aug., 1968], No. 37736/69. Heading B5A. [Also in Division B3] A rolling mill stand for rolling metal or plastics sheets is provided with prestressing units and with means for bending the work rolls in a sense to counteract their bending under rolling loads, the bending load applied to the rolls being dependent on the stress in the stand. The prestressing units may be wedges 19 located between the working or backing roll chocks (parts I and II of the figure), or may be associated with the roll chocks 4 or screwdowns 14 (parts III and IV). Changes in the rolling load are accompanied by compensatory changes in the prestressing load in order to keep the combined stress, and hence the workpiece thickness, constant. The backing rolls 3, 3<SP>1</SP> of the mill can be controllably bent using pistons 9a coupled to the roll ends. The pistons are hydraulically connected with pistons 13 or 17 subject to the rolling load. Thus, changes in the rolling load automatically vary the bending forces applied. The pistons 13 and 17 are housed within transverse beams 7 and 15 positioned between the roll chocks and the housing windows. The work rolls can be bent in the case of a 2-high mill, and mechanical lever systems can be used in place of the bending systems shown.

Title: Fluid couplings
IPC: F16D33/20
Filed: 1973-08-09
Abstract: 1484011 Hydrodynamic couplings FLUIDRIVE ENG CO Ltd 8 Aug 1974 [9 Aug 1973] 37840/73 Heading F2W A scoop-trimmed fluid coupling for driving a conveyer or fan comprises an impeller 5, a turbine 6 having between 10 and 35% more vanes than the impeller 5, a baffle 11 of diameter at least 1À25 times the inner profile diameter of the working circuit, and two sets of holes 13, 14 drilled in the impeller, the centres of the holes 13 being spaced from the coupling axis by 53 to 63% of the outer profile radius 12 of the working circuit and the centres of the holes 14 being spaced from the coupling axis by 65 to 75% of the outer profile radius 12. The above arrangement provides a transmitted torque which remains substantially constant as slip in the coupling decreases. The filling of the coupling is controlled, during starting, by a scoop tube 7 which is withdrawn from a scoop chamber 9, for increased filling, when the supply current to a driving electric motor and thus the torque on the motor is below a predetermined value. As the coupling fills and accelerates the load, the torque on the motor and thus its supply current increases until the predetermined value is attained whereupon a current sensing unit 115 energizes a relay 116 which in turn deenergizes a relay 117 to stop an electric motor 111 which withdraws the scoop tube 7 from the scoop chamber 9. As the speed of the load increases and its rate of acceleration decreases the torque on the motor and thus the supply current to the motor decrease until the latter falls below the predetermined value whereupon the relays 116, 117 are respectively de-energized and energized to restart the motor 111 to continue withdrawal of the scoop tube 7 from the chamber 9 and thus further increase filling of the coupling. This cycle is repeated until the coupling is filled and the load running at its normal speed. When the motor 101 is stopped the motor 111 may be reversed to move the scoop tube 7 into the coupling empty position.

Abstract: 972,345. Hydraulic reciprocating motors. CONTINENTAL OIL CO. Oct. 9, 1962, No. 38231/62. Heading F1A. In a double-acting motor, e.g. for reciprocating a mass in a seismographic surveying system, and operating at high pressures and frequencies such that compression of the hydraulic fluid occurs at the end of each stroke, the porting 43, 48, 46 at each end of the cylinder 10 is dimensioned such that the volume of hydraulic fluid within the porting is reduced without reducing the radial cross-sectional area of the flow path of the liquid through the porting. Each port 43 opens into an annular groove 48 which is eccentric relative to the piston rod axis, Fig. 2, and opens into an annular passage 46 surrounding piston rod 12a, 12b. The sum of the flow cross-sectional areas at points b and c of groove 48, Fig. 2, is substantially equal to the flow cross-sectional area of port 43 and also to that of passage 46. Cylinder 10 may be coupled to the mass through flange 42 or may be mounted within the mass.

Abstract: 1,191,627. Measuring differential temperature, electrically. COAL INDUSTRY (PATENTS) Ltd. Aug.23, 1967 [Aug.26, 1966], No.38463/66. Heading G1N. The heat exchanged by a fluid in passing through a conduit, e. g. a radiator in a hot water heating system, is determined by two thermistors Th 1 , Th 2 , Fig. 1 disposed in the liquid flow passage at the inlet and outlet of the radiator respectively, and connected in a bridge circuit the unbalance output of which is proportional to the differential, temperature. The bridge output is used to control the supply of current to a heater h which heats thermistor Th 2  until its temperature is nearly equal to the temperature of Th 1  thereby reducing the resistance of Th 2  which tends to rebalance the bridge. The current in the heater is thus proportional to the difference in temperature across the radiator and to the heat output thereof, an indication of which is provided by a KWhr meter the current coil of which is in series with the heater and the voltage coil being energized from the mains supply. The flow-rate of the liquid is also taken into account since if the flow-rate is increased Th 2  will be further cooled thereby and the heater current will increase. Heater Energizing Circuit. When the bridge circuit (R 1 , R 2 , Th 1 , Th 2  ) energized by transformer TRM, is unbalanced a transistor T 1  is caused to conduct and half wave rectified current pulses of amplitude proportional to the out-of balance signal flow in the primary of a transformer Tr 1  . Current pulses from the secondary of Tr 1  are amplified by a transistor T 2  and passed to a transformer Ta1 where the signal is modulated the primary of Ta 1  being connected to a smoothed D. C. Source RF. The modulated signal causes a power transistor T 3  to produce current pulses in the heater winding h which heats the fluid which is to flow over the thermistor Th 2  raising its temperature and reducing its resistance thereby tending to restore bridge balance. The heater is located within the thermistor Th 2  as shown Fig. 2. Alternatively Fig. 3 (not shown) the heater may be mounted together with Th 2  within a housing disposed in the fluid conduit and having a bulbous upstream end, an inlet for fluid in the downstream end and an outlet at the upstream end so that liquid flow counter to the main flow and at a rate proportional thereto passes firstly through the heater and then around Th 2 .

[Also in Group XXXV] An electric motor control system comprising a split phase induction motor has a temperature-sensitive element embedded in the motor windings such that should the motor temperature rise above a predetermined value the supply thereto is removed. A split phase motor 2 driving a refrigerator pump has a sealed bimetal switch 23 embedded in the motor windings 12, 13, the circuit including a composite bimetallic switch 26. At starting a circuit is established from supply terminal 31, bimetal 34, contacts 35, 37, contacts 40, 44, heater 42, bimetal 46 and thence simultaneously firstly by way of conductor 48, main running winding 12 to supply terminal 32 and secondly, link 50, contacts 49, 51, arm 52, starting winding 13 to supply terminal 32. Thus both running and starting windings are energized. After a time sufficient to enable the motor to start the starting current through the bimetal 34 will cause it to deflect sufficiently to open contacts 49, 51 to de-energize the starting winding 13 whereafter the motor will run normally. If the motor becomes overloaded a greater current will flow in the bimetal 34 causing it to deflect further, thereby engaging peg 58 to open contacts 40, 44 to remove the short-circuit on the bimetal 38. Bimetal 38 will now carry current and the combined effects of this current and heater 42 cause the bimetal 38 to deflect sufficiently to open contacts 35, 37, thereby deenergizing the motor 2. In the event that the motor 2 becomes overheated the contacts of the bimetal switch 23 close, whereby the additional heater 53 becomes energized. This heater is sufficient in itself to cause the bimetal 38 to deflect and open contacts 35, 37 to remove the supply from the motor. The peg 58 is provided to ensure that contacts 40, 44 remake before contacts 49, 51.

Title: Process for the manufacture of alkali metal phosphates
Inventor: HARTLAPP GERHARD
IPC: C01B25/39
Filed: 1959-11-18
Abstract: Alkali metal phosphates of the type (P2O5)x (Na2O)y, where the ratio x:y is between 1 and 0,5, are prepared by feeding finely divided alkali metal chloride, specifically sodium or potassium chloride, in the presence of oxygen but in the absence of water vapour, into a downwardly-directed phosphorus flame fed with molten phosphorus. In order to prevent the formation of phosphorus oxychloride, the oxygen should be in at least 30% stoichiometric excess.  The hot reaction product is dissolved outside the flame region in an aqueous medium preferably having a pH of 7 or less, whereby the chlorine formed is not dissolved.  The alkali metal chloride is sprayed into the flame by a nozzle at about the same height as the phosphorus inlet or higher.  According to a typical example sodium chloride, substantially all of which is below 0,1 mm. particle size, is suspended in oxygen and atomized into a phosphorous flame fed with molten phosphorus and oxygen-enriched air in proportions such that the P2O5:Na2O ratio is 1:1,3.  The flame temperature is about 2000 DEG  C.; the reaction product leaves at 600-700 DEG  C. and is cooled by chilling with water and simultaneously dissolved.  Crystallized phosphate is obtained from the solution by known methods.  The hot waste gases still contain about 10% of alkali metal phosphate and are washed with concentrated phosphoric acid solution, whereby the phosphate is separated and chlorine gas, suitable for the production of hydrochloric acid, remains.  A further example relates to potassium chloride.
