Abstract: 472,707. Vulcanizing-presses. STEVENS, A. H. (Allen, R. S.) April 27, 1936, No. 11955. [Class 70] [Also in Group IX] A web 101 of unspun fibres, or of yarn fed from a roll is plaited or folded around severable separator strips 99, which may be of chipboard and the superposed strips with the web folded around them pass between adjustable plates 146, 147. Cementing materials such as rubber latex or a compound thereof is sprayed from nozzles 187 on the surfaces of the plaited structure exposed through diagonal slots 184, 185, in the plates 146, 147, along which a frictioning roller reciprocates. The cemented plaited structure is next dried by hot air and cemented base or backing fabrics from rolls, are united with the faces of the plaited structure. The composite material is then consolidated and vulcanized by passage between the vertical platens 241, 245 of an upper press unit and the corresponding platens 233, 240 of a lower unit. The platen 241 is fixed to frames 231, 232 guided by posts 224, 225, and partly counterbalanced by a hydraulic cylinder 250 and controlled by cams, the platen 245 being attached to the piston rod of a hydraulic ram 243. The platen 240 of the lower press unit is attached to hydraulic rams 235, 236 carried by movable frames which are partly counterbalanced and controlled by cams. The press units are raised quickly and descend slowly, one rising when the other falls, the supply of water to the hydraulic rams being regulated so that the platens only contact with the material when the corresponding press unit descends, the rate of this descent corresponding with the rate of formation of the plaited material. This is afterwards split to produce two pile fabrics.

Abstract: 1,057,794. Infrared analyzers. USTAV PRO VYZKUM AVYUZITI TUHYCH A PLYNNYCH PALIV. March 23, 1965 [April 7, 1964], No. 12197/65. Heading G1A. A non-dispersive infrared analyzer has a single beam source (1); a test absorption cell (3) which will contain the substance to be tested; first and second absorption chambers (4, 5) being arranged in series and divided by a window capable of transmitting infrared radiation, containing samples of the substances to be tested for, at substantially equal static pressures, and being connected to a common detector (6); and means to adjust the path length of the radiation in at least one of the chambers (4) such that the absorption length of the first chamber (4) is kept less than that of the second (5). In a first embodiment the chambers (4, 5) are divided by a movable window (10) which is slidable by an elastic member (11), to alter the path lengths. A second embodiment utilizes a fixed partitioning window, the alteration in the path length being carried out by means of a transversely movable or rotatable reflection surface (13) which reflects the required proportion of radiation back into the second chamber (5) through the infrared transmitting end window (12). The reflecting member may be a movable element operated by means of the feedback loop of an analyzer operated by compensation measurements. Both methods of changing the path length may be used in a single instrument. The path length is altered during zeroing of the analyzer, when the cell (3) contains a non-absorbing substance, in order to obtain zero output from the detector and zero indication on meter (9) connected via amplifier (8). Chopping of the radiation beam is by a rotating shutter (2) and the detector (6) is of the diaphragm condenser type.

Title: Electronic circuit for quartz crystal watch

Filed: 1972-03-17
Abstract: 1350721 Electronic watches DAINI SEIKOSHA K K 17 March 1972 [20 March 1971] 12637/72 Heading G3T A drive circuit to drive an electro-mechanical oscillator (e.g. in a watch), comprises a crystal controlled oscillator circuit 1, Fig. 1, the output of which (at 16384 Hz) is divided by a chain of fourteen divide-by-two M.O.S.F.E.T. frequency divider stages to produce a timing pulse train at 1 Hz and pulse width of 500 m secs. A wave shaper (WS), Fig. 2, (not shown), reduces this width to 8 m secs in order to reduce power consumption. Pulses from the shaper at a terminal 2d are applied to a bi-stable circuit 4 and via a diode D to a monostable circuit 5 which controls the bi-stable circuit so as to pass current alternately in opposite directions through a coil L of the electro-mechanical transducer. A permanent magnet armature of the transducer is thereby caused to oscillate. In the oscillator circuit 1 a crystal 1a is maintained oscillating by a circuit including a transistor 11. A capacitor 11 compensates for frequency drift due to temperature changes. Capacitors 12, 13 are for fine and coarse frequency adjustment respectively. A timing pulse output at 2d comprises a train of positive pulses which render transistors T41, T42 conductive so that current passes through coil L in a direction "A". When the voltage at 2d decreases a normally conducting transistor T51 becomes temporarily non-conducting so that T45, T43 are permitted to conduct. This causes current to flow in coil L in the opposite direction B. Meanwhile the charge in a capacitor C51 increases the potential at the base of T51 which again conducts. The non-conducting period of T51 depends upon the time constant of R51 C51. In Fig. 3, a transducer for a watch comprises a permanent magnet 9 mounted on the axle of a pallet 8 and co-operative with the driving coil L which is wound on a magnetic core 7. The pallet drives a seconds wheel 10 and hand 13 in known manner. A limit spring 14 engages a gear wheel 12 coaxial with wheel 10. SETTING A switch 3, operated via the watch crown, applies a negative potential to a point 2e thus blocking the divider stages subsequent to the tenth stage so that the watch is stopped - when the crown is in one position. The watch is restarted by pushing the crown to its other position to synchronize with a reference time.

Nitrilotriacetonitrile is prepared by reacting in liquid phase hydrogen cyanide, formaldehyde and methylene-bis-iminodiacetonitrile. The latter compound may be formed in situ by adding liquid hydrogen cyanide to a liquid phase adduct of formaldehyde and ammonia while maintaining the pH of said phase at a strongly acid value (< 2). The order of addition of the HCN and HCHO can be varied, and sufficient of one or other of these reagents may already be present in the intermediate methylene-bis-iminodiacetonitrile phase to complete the synthesis without further addition. The temperature of the reaction is preferably kept between 50‹ C. and 85‹ C., while the initial step of producing methylene-bis-iminodiacetonitrile is effected below 50‹ C., or by addition of ammonia and HCN in two stages, at approximately 35‹ C. and 65‹ C. respectively.

Abstract: 886,970. Production of stainless steel. STRATEGIC-UDY METALLURGICAL AND CHEMICAL PROCESSES Ltd. April 15, 1959 [April 16, 1958; Jan. 29, 1959], No. 12865/59. Class 82(1). Complex oxide ores of iron, nickel and chromium are reduced with sufficient reducing agent in one or more stages to form a ferro nickel alloy containing all the nickel of the ore and also a ferro chrome alloy with only a portion of the chromium content of the burden, the total recovery of iron, nickel and chromium corresponding to the proportions of these materials desired in a stainless steel, and refining the ferro nickel and ferro chromium alloys together to produce a stainless steel. By the selective process, (Fig. 1) a reduction burden containing nickel, chromium and iron is calcined with fluxes and may be partially reduced to produce a free flowing sinter which is reduced with a carbonaceous reducing agent at 1550-1650‹C. in a first stage furnace to produce a ferro-nickel alloy containing all, or substantially all, of the nickel present in the burden. The slag from the first stage furnace is reduced in a second stage furnace with sufficient reducing agent to reduce most of the iron to a semi steel, while leaving the chromium in the slag for further reduction in a third stage furnace with a carbonaceous, or non-carbonaceous reducing agent, to produce ferro-chrome. The ferro-chrome and ferro-nickel are combined in suitable proportions in a refining furnace to produce stainless steel. Alternatively, the proportion of the reduction burden may be so adjusted that the first stage reduction (Fig. 2) produces a steel corresponding approximately to the desired final composition and the slag is further reduced in a second stage to produce ferro-chrome part of which may be added to the "steel blend" in the steel refining furnace to produce a stainless steel of desired composition by reducing the carbon content to the desired level and adjusting the proportions of the alloying constituents.
