Title: Digital measuring instrument and densimeter
IPC: G01F1/90
Filed: 1961-10-19
Abstract: 999,625. Estimating density. D. M. POTTER. Oct. 19, 1961, [Oct. 25, 1960], No. 37553/61. Heading G1S. [Also in Divisions G4 and H2] Apparatus for measuring density comprises a shaft 28, Fig. 3, carrying three floats 38, 42, 44 which are submersible in the liquid the density of which is to be measured. The floats are in fixed angular relationship with each other, but floats 42, 44 may be adjusted to different radial distances from shaft 28. In order to adjust the apparatus to measure specific gravities within a given range, e.g. from 0.880 to 0.680, the chamber 12 is filled with a liquid having the higher density, and the radial position of float 42 is adjusted until float 44 extends vertically downwards. Chamber 12 is then filled with a liquid having the lower density and the radial position of float 44 is adjusted so that shaft 28 assumes a given angular displacement e.g. 40 degrees from its initial position. Liquids having intermediate densities then produce an angular displacement within the 40 degrees range which is linearly proportional to their density. Float 38 is of solid glass having a low thermal coefficient of expansion, and floats 42, 44 similarly have a low coefficient of expansion but are of a solid metal alloy. Chamber 12 has an inlet 45 and two angularly spaced outlets 47, 49, liquid entering the chamber having to pass through a narrow anular space formed by a baffle 51. Shaft 28 positions an output member by means of a magnetic coupling (Division H2), and the position of the output member is measured electrically (Division G4). Specification 896,952 is referred to.

Title: Treatment of polymeric films
IPC: G03C1/91
Filed: 1972-08-11
Abstract: 1394261 Polymeric film treatment EASTMAN KODAK CO 11 Aug 1972 [13 Aug 1971] 37622/72 Heading B5B [Also in Division G2] A coruscate electrical discharge at a voltage in the range of 19-34 kv., is passed across the surface of a polymeric film to improve the dry and wet adherence of a coating to the substrate. By a coruscate discharge is meant one that involves intermittent flashes or sparkles that appear to wiggle or travel along many random or varied paths, and are similar in colour to a hot oxidizing flame. The voltage may be 22-34 kv., especially 30-34 kv., and the current from 5-20 ma. A discharge at 34 kv. and 5 ma., using a commercially available frequency, e.g. 60 Hz, is preferred. Polyester film may be used, especially polyethylene terephthalate. In apparatus as shown, the film 12 passes over a bare metal roller 10, which may or may not be earthed through switch 11, and is subjected to the electrical discharge field illustrated as randomly directed zig zag lines 4 achieved by the pair of parallel metal rod-like electrodes 6 and 8. Electrode 8 is earthed and may be cylindrical or have any other suitable configuration. Electrode 6 may be in the shape of a razor blade, but is preferably a threaded rod as shown. Random tracks are formed in the film surface. If electrode 6 is as wide as film 12, arcing occurs over the edges of the film to metal roller 10. This may be obviated using the apparatus of Fig. 2, in which a metal roller 20 is mounted on a metal shaft 24 and provided with dielectric end caps 22. To minimize arcing through the interface between the film and the outer periphery of the end caps 22, electric arc knives or nozzles 23 are provided on an electrode support 25 at each end of the roller, through which high pressure air is directed across the edges of film 12. Film so treated, which may include semicrystalline oriented polyethylene terephthalate shows excellent wet and dry adhesion to photographic emulsions.

Title: Nuclear reactor with solid substance moderator of variable slowing-down power
IPC: G21C7/26
Filed: 1965-09-06
Abstract: 1,114,285. Reactors. R. SCHLOTTAU. 6 Sept., 1965 [17 Sept., 1964], No. 37960/65. Heading G6C. A reactor with a solid moderator core is controlled by forming the moderator from zirconium hydride and zirconium deuteride rods, or zirconium hydro-deuteride rods, some or all of which are replaceable to vary the hydrogen-deuterium ratio. In one embodiment the reactor core comprises moderator rods of zirconium hydro-deuteride between which the fuel rods are introduced. Two stocks of moderator rods are used, in one of which the hydrogendeuterium mixture comprises 20% hydrogen and 80% deuterium, while in the other stock this mixture comprises 80% hydrogen and 20% deuterium, and by appropriate distribution in the reactor core it is possible to obtain from both rod stocks almost continuously any desired hydrogen/deuterium ratio. Alternatively, a number of stocks of rods of various hydrogen/deuterium ratios are used and, in addition, stocks of pure zirconium hydride and zirconium deuteride rods. It is also possible to replace one or more of the above rods by canned or uncanned rods which contain graphite, beryllium or beryllium oxide in order to influence the neutron flux distribution.

Title: Exhaust gas sensor operating detection system
IPC: F02D45/00
Filed: 1975-09-16
Abstract: 1473057 Exhaust gas analysers BENDIX CORP 16 Sept 1975 [6 Nov 1974] 38040/75 Heading G1N Apparatus for monitoring the condition of an oxygen sensor located in the exhaust system of an I.C. engine comprises means for measuring the time intervals between pulses developed continuously by the sensor in response to the fuel injections into the cylinders, these time intervals are extended with reduced efficiency of the sensor and are compared with the relaxation time of a monostable multi-vibrator. The signals from the oxygen sensor 10, Fig. 2 are normally fed to a control unit 120 to determine at 22 the duration of fuel injection to each cylinder, to maintain a fuel/air ratio consistent with a desired oxygen content in the exhaust gases. The sensor signals form a pulse train fed to a monostable multi-vibrator 14 which is triggered by the lagging edges to produce a train of square pulses each of which discharges capacitor 48. The charging circuit for capacitor 48 has a long time constant so that its voltage at discharge is indicative of the time interval between the discharge pulses. This voltage is compared at the emitter 108 of a transistor 102 with a pre-set voltage on the base log. If the former exceeds the latter transistor 102 conducts, followed by transistor 114 which sends a signal to a timer 128 to operate a lamp or buzzer and unbalance the fuel injection system and cause the engine to behave roughly, in a manner which indicates that the oxygen sensor is failing. The monitoring of the oxygen sensor by sensing the maximum voltage on capacitor 48 is only effected when pre-selected parameters of the I.C. engine are all within pre-set limits. One parameter limit is attained when the fluid-flow signals 28 have been arriving at a transistor 73 for a time and at a frequency sufficient to discharge capacity 70 to a reference level. This causes a transistor 79 in comparator 46 to cease conducting and remove an earth clamp from capacitor 48. A second parameter limit is attained at idling conditions when spaced signals 30 are sufficiently spaced to allow a capacitor 82 to be charged from a voltage source 32, which is only high when the engine throttle is closed, to the reference voltage level of comparator 46. A third parameter limit is attained when the engine coolant temperature exceeds a predetermined value. This produces a high level on signal 34 which blocks a diode 44 leading to capacitor 48. Thus the oxygen sensor testing circuit is only enabled when the selected engine parameters are all within pre-set limits.

Patent GB-1000848-A (GB)
Title: Improvements in or relating to spinning frames
IPC: D01H1/38
Filed: 1962-10-10
Abstract: 1,000,848. Ring-rail apparatus. DENCO A.G. Oct. 10, 1962 [Oct. 13, 1961], No. 38338/62. Heading D1D. A control device for a spinning-frame having mechanism for driving the ring-rail to produce cops of predetermined formation, comprises first means for displacing the ring-rail at the end of the normal wind to build a tip-bunch, a second means for automatically displacing the ring-rail from the bunch-building position to a lower doffing position and means for locking it there. In Fig. 1, the ring-rail 13 is traversed by pokers 14 or arms 16 counterweighted at 17 on shafts 19 with interconnected quadrants 18 one of which is connected by a chain &c. 21 to a pulley 22 Fig. 2. This is fixed to a shaft 45 geared at 60, 62 to a shaft 62 clutched at 74 under the control of a solenoid 73 to a pulley 67 connected by a chain &c. 78 to a builder-motion 80. Thus with the solenoid inactive and the clutch engaged, pulley 22 is rotated by pulley 67 gradually to pay-out chain 21 and allow the counterweights 17 to raise the ring-rail to effect the build. A spring 69 ensures that the chain does not become slack. Shaft 45 is connected to the output side of an electromagnetic clutch 40, the input side of which is constantly drawn by the drafting-mechanism 24 through gearing 26, 27. When solenoid 73 is energized, the clutch 74 is separated; with clutch 40 energized, pulley 22 is rotated to wind in the chain 21 and lower the ring- rail in controlled fashion. When the rail reaches doffing position, a spring-urged plunger 53 snaps into a recess in a pulley 51 on shaft 45, and locks the ring-rail. At this point, an enlarged part 54 of the plunger opens a normally-closed switch 82. The solenoid 73, clutch 40 and the frame-motor are in circuit with switches which are controlled by a timer 86. This is set into operation by a limit switch 81, which is momentarily closed when the ring-rail reaches a position when the normal build is completed. The actuation of the timer immediately completes a circuit to "lock. in" the timer-motor which thus continues to operate when switch 81 re-opens; it also closes a switch to complete a circuit for the solenoid 73 which is thus energized, to de-clutchpulley 67 from shaft 62. The pulley thus freed from the control of the building- mechanism allows the ring rail to be raised by the counterweights 17 to a position where tip-bunches are built. After a pre-set time, the timer closes a switch to complete a circuit for clutch 40 which is thus engaged to drive pulley 22 from the drafting- mechanism, to wind-in the chain 21 and lower the ring-rail. When it reaches doffing position, it is locked as above described and switch 82 is opened to break the circuit to clutch 40. Timer 86 now opens the circuit for solenoid 73, so that the pulley 67 and shaft 62 are again clutched together, and to open the circuit to the frame motor. A motor start-switch 125 and stop-button 130 are provided. Pulleys 22 and 67 can be changed to vary the rate of the build and of the descend of the ring-rail.
