Title: Improvements relating to electric irons
IPC: D06F75/14
Filed: 1955-09-01
Abstract: 776,857. Steam irons. HOOVER, Ltd. Sept. 1, 1955 [Sept. 2, 1954], No. 25174/55. Class 138 (2). In a steam iron, including a water reservoir 11 having an outlet 27 leading to a boiler 16 and having formed in it a reserve compartment 63 and a water head compartment 64, the lower portion of the latter communicates with the outlet and has a restricted plan area, so that a given volume of water in it will exert a greater head than the same volume would if the reservoir were not divided, and means are provided for causing water to flow from the reserve compartment to the head compartment when the iron is tilted from and then back to its operating position. A partition 60 dividing the reservoir into the two compartments 63, 64 slopes very slightly down towards the toe end of the reservoir where it is provided with an opening 71 connected by a tubular passage 70 to the outlet 27. The partition 60 also has openings 67, 68, each surrounded by an upstanding flange 69 forming a weir to prevent water in the compartment 64 from flowing back into the compartment 63. The outlet 27 is controlled by a needle valve 53 operated by a stem 51 and valve actuator 56.

Title: Methods of facilitatint exact evaluation and control of the processing of a product mass and apparatuses for carrying said methods into effect
Inventor: FALKE E
IPC: A24B3/04
Filed: 1974-06-06
Abstract: 1452664 Automatic control systems SVENSKA TOBAKS AB 6 June 1974 [7 June 1973] 25218/74 Headings G3N and G3R In a system in which a mass of material (tobacco) is conveyed from one location to another measured values of the weight per unit time and the moisture content are fed to a computer which derives the solids content of the mass and the moisture which must be added to achieve a desired ratio of moisture to solids and also controls the process. As shown, moisture content is measured by a capacitance or infrared radiation device 16 and the weight by a belt weigher 20. The output of the computer 19 (not described) controls the speed of a motor driving belt 3, using thyristors, so as to keep the dry weight per unit time constant, and also adjusts via 26 the flow of water sprayed at 9, in a "saucing drum" 5. Also in this drum is added steam at 11 and sauce at 7 (of known moisture content) and the quantities of these substances may be controlled by the computer as well as, or instead of, the water supply. Alternatively, constant amounts of moisture and sauce may be added and the speed adjusted to produce the desired moisture in the output.

Title: A process for the fractional distillation of niobium and tantalum halides
IPC: C01G33/00
Filed: 1957-08-09
Abstract: An anhydrous mixture of the pentochlorides of niobium and tantalum and at least one other chloride that tends to incrustation by distillation is fractionated by distilling in the presence of at least one anhydrous high-boiling metal halide and/or at least one co-ordination compound thereof, the metal halide or co-ordination compound having a higher boiling point than either the niobium or tantalum pentachloride and reducing both the partial pressure of the other chloride in the mixture tending to incrustation and also the melting point of the mixture. The high-boiling metal halide or co-ordination compound may be the phosphorus oxychloride adduct of anhydrous aluminium chloride, or the alkali metal or alkaline earth metal halide double salts of iron, zirconium or hafnium halides, in particular the salts of formula Na[FeCl4] and Na[AlCl4]; in addition corresponding double salts derived from potassium, lithium, rubidium, or caesium chlorides may be used.  The halide mixtures to be fractionally distilled may be obtained by the chlorination of the appropriate natural products in the presence of carbon.  In a typical example, briquettes made from 80 parts of columbite ore and 20 parts of soot are heated in a furnace and continuously treated with chlorine gas.  The resulting solid mass, which comprises chiefly niobium and tantalum pentachlorides together with iron chloride and other chlorides as impurities, is mixed with the adduct prepared from phosphorus oxychloride and anhydrous aluminium chloride and subjected to fractional distillation in an atmosphere of carbon dioxide. Phosphorus and iron do not distil, and TiCl4, SnCl4, and SiCl4 are contained in the first fractions.  Niobium and tantalum chlorides of 97-98% purity are distilled in the 230 DEG -260 DEG C. fraction.

Title: Improvements in or relating to the production of monohydroxydiethers of trihydric alcohols
Inventor: DELIUS HERMANN
Filed: 1964-06-18

Title: Speed control system for electrically powered mechanism
Inventor: EISENGREIN ROBERT HENRY
IPC: H02P23/00
Filed: 1959-07-23
Abstract: 923,340. Automatic speed control. SENECA FALLS MACHINE CO. July 23, 1959, No. 25339/59. Class 38 (4). [Also in Group XXXVI] A circuit for sensing the load on an induction motor has a first input signal derived from the phase-to-ground voltage V 1 , a second input signal (voltage V,) being obtained from a current transformer in the line from which voltage V 1  is derived. Voltages V 2 , V 3  represent the transformed values of V 1 , and the rectifier D i  accepts the algebraic sum of V 2 , V 4  to produce voltage V 5 , whilst voltage V 6  is the sum of voltages V 3 , V 4 . Voltage V 7  is then the sum of voltages V 5 , V 6  and has a magnitude directly proportional to the current in phase with the voltage V 1 . The combined action of potentiometer P 1  and capacitors C 1 , C 2 , filter the voltages V 5 , V 6 , and provide a smooth direct voltage V 7 , the potentiometer providing means for balancing V 7  to zero for a particular load. An A.C. tachometer generator supplies a signal Vt whose phase reverses with reversal of the motor shaft. This signal is amplified and has its magnitude limited to a constant value VtL to provide a constant voltage V 9  acting as the carrier input to a ring modulator 20, V 7  being the D.C. input to the same modulator. The output voltage V 8  is thus an A.C. signal with the same phase as V 9  and whose magnitude is proportional to V 7 . In a modification, the voltage V 9  is connected to a demodulator and is compared with a reference voltage to provide a resultant voltage whose magnitude is proportional to V 9  and whose polarity reverses as the phase of V 9  reverses. This resultant voltage operates a polarity-sensitive relay to control the D.C. load signal V 7 , whereby a signal of the correct polarity, in accordance with the direction of rotation of the motor, is provided, Fig. 6 (not shown). The A.C. motor may be the prime mover of a mechanical amplifier with an integrally coupled servomotor and tachometer to provide low-level torque and speed. A speed reference potentiometer provides an A.C. signal to an electronic amplifier which also receives a signal from the tachometer. The amplifier output forces the servomotor and tachometer to reach a no-load speed corresponding to the setting of the potentiometer. By adding a load-responsive signal, the speed may be held constant with changing load, or may be varied in a predetermined manner, Fig. 5 (not shown). The load-responsive circuit may provide a speed boost when the load exceeds a predetermined value so that speed-drop may be corrected for variable loads above any fixed losses. For three-phase systems without an earthed star-point, the voltage V 1  is derived from two phases of the supply through a resistance-capacitance network, Fig. 3b (not shown). Specification 686,650 is referred to.

Title: Dental appliance having a plurality of instruments
IPC: A61C19/00
Filed: 1978-05-31
Abstract: Each of the instruments is assigned a removal signal generator and a logic circuit, each of these logic circuits being connected by means of a single logic line (8) to the assigned removal signal generator (3). Each of the logic circuits (4) generates an activation signal for the assigned instrument (1, 101) and delivers a blocking signal to the logic line when a removal signal from the relevant removal signal generator is present and at the same time no blocking signal is present from the other logic circuits. Each logic circuit (4) contains a memory or executes a storage function in which or by means of which the signal state prevailing during application of a removal signal on the logic line (8) is stored. The stored signal state is critical for the logic decision in an evaluation circuit as to whether to generate an activation signal or a blocking signal. <IMAGE>
