Title: Improvements in or relating to process control apparatus
Inventor: FRANCIS BRIAN
IPC: A47J27/62
Filed: 1961-04-17
Abstract: 936,050. Electric correspondence control. WEST INSTRUMENT Ltd. April 10, 1962 [April 17, 1961], No. 13802/61. Class 40 (1). An apparatus for controlling the duration of a process in accordance with the output from means 10 responsive to a physical characteristic such as temperature, comprises means comparing said output with a quantity which is periodically varied between values corresponding to an upper and a lower limit of the said characteristic at a rate to give two or more cycles of variation in the minimum treatment time, and a timing device such as motor 21 which operates only during periods when the magnitude of said output exceeds that of the comparison quantity. The duration of a process is varied in accordance with temperature within a range bounded by the minimum and maximum temperatures at which the treatment can be carried out, so that the duration is a maximum when the temperature is at its minimum value, and vice versa. The output from a thermocouple or a resistance thermometer 10 energizes a temperature controller not shown, and determines the position of a pointer 11 which moves over a scale 12, a corresponding member 17, and a contact 18 which co-operates with a contact plate 19 carried by a member 14. The member 14 is carried cyclically between the upper and lower scale values suitable for the process by a motor driven cam 15, the shape of which is determined by the required process temperature/duration relationship, and the periodicity of which is such that at least 20 cam revolutions are performed in the minimum permissible process time. A motor 21, which drives the programme disc of a process timer 22, is energized from a supply 20 and through switch member 17 only when the latter is " up-scale " of the swept pointer 13. Thus the timer will not be energized when the pointer 11 and member 17 are below the minimum value of the swept range of pointer 13 but once this minimum value is exceeded by the pointer 11, then the energization period of the timer will increase. The rotation of the programme disc thus integrates all those periods of time during which the pointer 11 is " up-scale " of the swept pointer 13 and after a predetermined rotation terminates the process by, for instance, effecting the removal of the object under treatment from the furnace.

IPC: G07B13/04
Abstract: 138,807. Richardson, H., and Palmer, E. H. July 3, 1919. Flag and setting-spindle mechanism; illumination arrangements.-An electric switch is clamped to the flag-post or other setting-means of a taximeter so that the setting thereof serves to effect illumination of a "For Hire" or "Engaged" indicator. The switch is contained in a casing 1 secured to the flag-post 3 co-axially with its pivot 5 by means of a clamping arm 2. Within the casing an arm 12, loosely mounted upon a pivot 11, is kept upright by engagement of a pin 19 thereon with a weighted arm 17 also loosely mounted on the pivot 11. The arm 12 carries a bridge member 13 adapted to maintain contact with an inner flexible contact member 16 and to engage either of a pair of outer arc-shaped contact members 7, 8 according to the position of the flag-post 3 with which the casing rotates. The contact members 7, 8, 16 are secured to the insulated base 6 of the casing by binding screws such as 9, 10, which are wired as shown in Fig. 2 to the indicators 20, 21 to be illuminated. An additional switch is provided in the circuit to put the device out of action in the day time.

Title: Improvements in or relating to ultra-sonic liquid level indicators
IPC: G01F23/296
Filed: 1965-04-02
Abstract: 1,090,652. Ultrasonic liquid level indicator. ZAVODNY V.I. LENINA PLZEN, NARODNI PODNIK. April 2, 1965 [April 2, 1964], No. 14154/65. Heading H4D. In a liquid-level indicator, ultrasonic surface waves are generated on a rod dipping into the liquid and are converted at the point of contact of the rod with the liquid into longitudinal waves which travel through the liquid and are reflected back to the said point of contact by a submerged reflector supported by a float. In the embodiment shown, the reflector 4 has a cylindrical or spherical surface and is supported by a float 9 which is guided by the rod 1 and moves with the liquid surface to maintain the centre of curvature of reflector 4 at the point of contact of the rod 1 with the liquid surface. The travel time of the ultrasonic waves between the reflector 4 and an ultrasonic source 3 or reference mark 10 provides an indication of the liquid level and may be determined using an oscilloscope. The whole indicator may be arranged in a pipe dipped into the liquid, and a portion of the inner pipe surface may perform the function of the rod 1. The indicator may be used in radioactive environments.

Abstract: 1390822 False twisting; open end spinning SCHUBERT & SALZER MASCHINENFABRIK AG 29 March 1972 [30 March 1971] 14866/72 Heading DID A rotating thread clamp comprises two coaxial thread guides 25, 35, at least one of which being displaceable relative to the other along the axis of rotation of the clamp, resilient means 61 pressing the thread guides together and a thread clamping member 5 arranged in a seat in the thread path between the two guides. The thread guides 25, 35 are separable by a fluid medium being fed to or withdrawn from a first space 50 which surrounds a sleeve 6 rotatably locking the thread guides 25, 35 together. A second space 52 communicates with the first space 50 via at least one opening in the sleeve 6. In operation the thread is clamped by ball 5 against the seats in the thread guides 25, 34. When air or liquid is withdrawn from the space 50 the guides separate and the ball 5 drops out of the thread path. The thread clamp may form part of an electrostatic open end spinning apparatus (Fig. 2 not shown). The guides (71, 75) are separated by compressed air and an air jet from bore (76) blows the ball 5 out of the thread path. In Fig. 3 (not shown) a yarn breakage detector (45) detects absence of passing thread from the open end spinning chamber and causes pneumatic pressure to separate the thread guides (8, 82). The ball 5 rolls from the thread path under gravity when the guides are separated.
Patent GB-725476-A (GB)
Title: Anti-oxidant
IPC: C09K15/14
Filed: 1953-05-28
Abstract: Sulphur-containing products useful as antioxidants for mineral oils are prepared by reacting an "acid oil" with an alkali metal hydroxide in amount equivalent to the thiophenols in the oil and with a halohydrocarbon having at least two but not more than twice as many halogen atoms as carbon atoms, in amount at most equivalent to the thiophenols in the oil, and removing the unreacted components, the alkali metal halide, water and resinous components from the reaction mixture.  By "acid oil" is meant the product containing thiophenols and possibly phenols, obtained in the refining of cracked gasoline by treating it with an alkaline solution and releasing the thiophenols and phenols from the alkaline solution by acidification.  The halohydrocarbon can be added to the acid oil simultaneously with the alkali metal hydroxide or after the thiophenolate has been formed. Specified halogen compounds are dichloro- and dibromo-methane, 1,2-dichloroethane, 1,1,2-trichloroethane and 2,5-dibromo-2,5-dimethylhexane.  Mixtures may be used.  The alkali metal hydroxide is preferably used in an aqueous or alcoholic solution, and reaction temperatures of 70 DEG  to 140 DEG  or higher are generally used.  The reaction mixture is afterwards separated into phases, if necessary by adding water, and the upper phase mixed with a diluent, e.g. gasoline.  It is then washed with water, treated with a little dilute acid and distilled.  The product may be deodorized by treatment with alcoholic caustic soda.ALSO:Sulphur-containing compounds which are substantially reaction products of thiophenolates and halohydrocarbons are used as antioxidants for mineral oils and for lubricants containing mineral oils.  The products are prepared by reacting an "acid oil" with an alkali metal hydroxide in amount equivalent to the thiophenols in the oil and with a halohydrocarbon having at least two but not more than twice as many halogen atoms as carbon atoms, in amount at most equivalent to the thiophenols in the oil, and removing the unreacted components, halide, water and resinous components from the mixture. By "acid oil" is meant the product obtained in the refining of cracked gasoline by treating it with an alkaline solution and releasing the thiophenols and phenols by acidification.  Special halohydrocarbons are dichloro-and dibromo-methane, 1, 2-dichlorethane, 1, 1, 2 trichloroethane, and 2, 5-dibromo-2, 5-dimethyl-hexane.
