Title: Apparatus for automatically controlling the movement of the back gauge of a paper cutting machine
IPC: B23Q15/24
Filed: 1956-12-06
Abstract: 847,932. Photo-electrically controlled paper cutting machines. LAWSON CO. Inc., E. P. Dec. 6, 1956 [Aug. 24, 1956], No. 37355/56. Class 40(3). [Also in Group VIII] A paper cutting machine comprising structural arrangements the same as shown in Specification 847,931 is provided with photoelectric control means modified in that the electric controller is arranged to be operated by only one photo-electric cell 190 carried by the carriage 127. The operation of the electric controller is started by pressing a "forward" push button which causes the clutch 160 of the low speed motor 145 to engage to advance the back gauge 105 at a low speed. After a predetermined delay due to a thermal relay in the controller, the low speed clutch is disengaged and the clutch 161 of the high speed motor 140 is engaged to rapidly advance the back gauge. As the back gauge 105 moves forwards the carriage 127 moves transversely and the light from the lamp 192 is eventually intercepted by the first stop unit 195. The relay PR-1 is thereby opened, causing the electric controller to disengage the high speed clutch 161 and engage the low speed clutch 160 so that the back gauge 105 and the carriage 127 move at the slow speed. The continued movement of the carriage 127 past the stop member eventually allows the light from the lamp 192 to again illuminate the cell 190 which then causes the electric controller to disengage the low speed clutch so that movement of the back gauge ceases. A green signal light then indicates to the operator that a cut may be made. The return of the knife after the cutting operation initiates the forward motion of the back gauge for the next cut, the position of which is determined by the next stop unit 195. However, should the operator hold the clamp down by means of a foot treadle, contacts in the controller remain open to prevent forward motion of the back gauge until the clamp is released. The electric controller is arranged so that manual readjustment of the position of the back gauge can be made without interfering with the automatic operation. Where a trim-out operation is required, a composite stop signal 195<SP>1</SP> is used having an additional leg 198. Specifications 707,089 and 707,090 also are referred to.

Abstract: 781,784. Regulating. SCHWEIZERISCHE LOKOMTIV-UND MASCHINENFABRIK. Dec. 29, 1954 [Dec. 31, 1953], No. 37525/54. Class 7(6) [Also in Groups XXIV and XXIX] A control system for a motor vehicle, such as a railcar, driven by an internal combustion engine 1, e.g. a Diesel engine, and employing a continuously variable ratio gear 4 which may be of the friction type as shown, or alternatively may be of the hydrostatic type, comprises a fluid pressure operated servo motor 13 to establish the ratio of the gear, an engine driven speed governor 21, and a control member 25, connected through links 26, 27 to the engine fuel control means 29, and to the output side of the speed governor 21; and to a slide valve 11 controlling the servo-motor. The position of the fulcrum point M of the control member 25 can be varied by hand operation of a crank 17, and the tension of a spring 19 in the speed governor 21 can be varied by operation of a crank 18, the two cranks operating by electro-pneumatic means (not further described). The friction gear shown consists of driving and driven rollers 5, 6 engaging idlers 8 on supporting shafts 7 tilted by the servomotor 13 to change the velocity ratio. The setting of the crank 18 determines the normal number of revolutions per minute at which the engine rotates, and the crank 17 determines the normal amount of fuel supplied to the engine. A change in the torque required at the driving wheels of the vehicle results in a change in both the amount of fuel supplied to the engine and also in the ratio of the gear 4. When equilibrium is finally restored in the system following the change in torque, the ratio of the gear has been so varied that the rate of delivery for which the fuel control means 29 is adjusted is the same as it was before the change of torque took place.

Abstract: 1,019,234. Distilling liquids utilizing the waste heat of a gas-turbine power plant. ESCHER WYSS A.G. Oct. 5, 1962 [Oct. 6, 1961], No. 37830/62. Heading BIB. [Also in Division F1] Liquid to be distilled, e.g. sea water, is heated, directly or indirectly, by waste heat given up in a cooler for a gaseous working medium, e.g. air, which is in circulation through a closed-circuit gas-turbine power plant comprising a compressor 1, a heater 3 and a turbine 4, the cooler comprising two sections the first of which, with respect to the direction of flow of the gaseous medium, is cooled by the transfer of heat to a boiling liquid. In the apparatus shown, the compressor is formed of two parts 1<SP>1</SP> and 1<SP>2</SP>, and there are two coolers 5 and 6 which remove waste heat from air circulating through the power plant. Steam at a pressure of less than 1 atm. abs. is raised from pure water in sections 5<SP>1</SP> and 6<SP>1</SP> of the coolers; and this steam is used to boil the sea water in the evaporator 16 of the distillation plant, which also comprises a second evaporator 17 and a condenser 21. The condensate formed in the heating-side of evaporator 16 is returned to sections 5<SP>1</SP> and 6<SP>1</SP> via heat-exchanger 18. Sea water, supplied through pipe 23, flows through elements 5<SP>2</SP> and 6<SP>2</SP> in the two coolers, wherein the sea water is preheated without evaporating. The greater part of the preheated sea water is used as coolant in condenser 21, and the remainder is passed via pipe 25 and heat exchanger 20 into container 22. From container 22, two streams of sea water flow, via heat exchangers 18 and 19, into evaporators 16 and 17. The steam formed in evaporator 16 is used to heat evaporator 17, which is operated at a lower pressure than evaporator 16. The distilled water formed on the heating- side of evaporator 17 is withdrawn from the system via heat-exchanger 19 and pipe 40. The steam formed in evaporator 17 is condensed in heat-exchanger 20 and condenser 21; and the distilled water is withdrawn from the system via pipe 43. Concentrated brine is discharged from evaporators 16 and 17 via pipes 31 and 33, respectively. In an example, steam at 74 ‹C. is generated at a pressure of 0À38 atm. abs. in sections 5<SP>1</SP> and 6<SP>1</SP>; and evaporators 16 and 17 are operated at 62 ‹C. and 49 ‹C., respectively. In an alternative embodiment, elements 5<SP>2</SP> and 6<SP>2</SP>, and condenser 21, may be cooled by atmospheric air. In a further embodiment, sections 5<SP>1</SP> and 6<SP>1</SP> themselves form the first stage of the distillation plant.

Title: Determination of the quantity of a gaseous element in a metal sample

Filed: 1972-08-14
Abstract: 1360166 Measuring gas content of metal INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE 14 Aug 1972 [12 Aug 1971] 37883/72 Heading G1N In a method of measuring the quantity of a gas in a metal sample, e.g. hydrogen in steel, a stream of a carrier gas is drawn over the heated sample and compared with a stream of the carrier gas alone in a catharometric bridge. The sample is induction heated in a chamber 13, Fig. 3, which has a gaseous curtain provided at one end 12 to allow the sample to be put in or removed without introducing external air. If the release of the gas to be measured is accompanied by the release of another gas, this other gas may be used as the carrier; for example in the case of hydrogen evolved from steel, nitrogen is also released. If nitrogen is used as the carrier gas its effects can be nulled in the bridge. In Fig. 3 nitrogen from source 1 is passed through valve 4 and along paths 2 and 3. The flow rate in these paths is set by capillaries 5, 14 and 16, and the gas is drawn through catharometric cells C 2 , C 3  by pump 17. Excess nitrogen vents at 29 so that the gas pressure in the paths is substantially atmospheric. The sample is heated in chamber 13, and a cooling fluid from this chamber keeps coils 18 and 19 heated to reduce stray currents of gas in the paths. When the sample is to be removed from the chamber, the chamber is opened, valve 9 is closed and valve 7 is opened to form a nitrogen curtain across the chamber mouth. The chamber may be by-passed by valves 21, 22 so that it can be serviced without cutting off the gas flow to the bridge, thus avoiding resetting the bridge. The bridge has two cells, C 1  and C 2 , and is balanced by resistors 23, 24, 25, Fig. 4(not shown). Any imbalance is amplified at 26 and converted to a frequency at 27. The total cycles provided by 27 in a given period are counted at 28 to give the quantity of gas causing the imbalance during that period.
