Title: Method of and means for regulating prime movers
IPC: G05D13/00
Filed: 1929-11-19
Abstract: 345,319. Fluid governors. SIEMENS SCHUCKERTWERKE AKT.-GES., Sie. mensstadt, Berlin. Nov. 19, 1929, No. 35371. Convention date, Nov. 28, 1928. Addition to 314,809, [Class 57, Governors &c.]. [Class 57.] A modification of the governor described in the parent Specification in which the valve 7 which maintains constant pressure behind the quantity valve 2 is operated by a piston 17 through an auxiliary control 16 to which pressure is delivered from the space 4 behind the quantity valve by the pipe 18. Pressure is delivered to the top and bottom of the cylinder of the auxiliary control device from pipe 18, port 19 is the overflow and pipes 14 and 24 lead to spaces 13 and 15 respectively. The piston 16 is guided by an extension passing through a gland and the excess upward thrust is countered by the spring 20. When the pressure in pipe 18 increases, the piston 16 moves upwards and uncovers the pipe 14 and the valve 7 is lifted to allow a greater flow. When the pressure in the pipe 18 falls, the piston 16 moves downwards under the influence of the spring 20 and uncovers the pipe 24 and the valve 7 is slightly closed. In the Specification as open to inspection under Sect. 91 (3) (a) the desired speed of the prime move is fixed by the tension allowed in the spring 20. This subject-matter does not appear in the Specification as accepted.

Title: Process for the manufacture of metallic compounds of the thiazole series
IPC: C07D233/86
Filed: 1929-11-21
Abstract: Complex compounds of heavy metals with amino- or imino-thiazoles which contain acid substituents capable of forming salts (including phenolic hydroxy groups) and of substitution products thereof are manufactured by acting on these compounds with salts, double salts, oxides or hydroxides of heavy metals in an alkaline, neutral or acid medium, with or without the addition of a solvent or diluent.  The products possess a strong therapeutic activity, and are soluble in water in the form of their salts with alkalis, ammonia or organic bases such as ethylene diamine, diethylamine and piperazine.  In examples: (1) to a solution of pseudothiohydantoin acetic acid and the equivalent of caustic soda is added an equivalent of silver nitrate solution, producing a precipitate of silver-pseudothiohydantoin acetic acid; by using twice the quantity of caustic soda the sodium salt of the acid is produced; the same sodium salt may be obtained by fusing the sodium salt of pseudothiohydantoin acetic acid with silver oxide, or by treating an aqueous solution of the sodium salt of pseudothiohydantoin acetic acid with silver oxide; (2) mercury-pseudothiohydantoin acetic acid is prepared from pseudothiohydantoin acetic acid and mercuric chloride; (3) the gold compound is similarly prepared using potassium aurichloride and may be converted into its sodium salt by treatment with caustic soda; a different compound (probably the aurous compound) is obtained by using a larger proportion of potassium aurichloride and working in the presence of sodium bisulphite; (4) the sodium salt of cuprous-pseudothiohydantoin acetic acid is prepared from pseudothiohydantoin acetic acid, cupric chloride, sodium bisulphite and caustic soda; (5) silver-a -methyl-m -aminothiazole-b -acetic acid is prepared from a -methyl-m -aminothiazole-b -acetic acid and silver nitrate; (6) silver-pseudothiohydantoin-m-benzoic acid is similarly prepared from pseudothiohydantoin-m-benzoic acid (obtained by condensing m-thiocarbaminobenzoic acid with chloracetic acid); (7) copper - p - hydroxyphenylpseudothiohydantoin is prepared by the action of cupric chloride on p-hydroxyphenylpseudothiohydantoin (obtained by condensing p-hydroxyphenylthiourea with chloracetic acid); (8) a -(silver-pseudothiohydantoin) - propionic acid is prepared from a-(pseudothiohydantoin)-propionic acid and silver nitrate.  The Provisional Specification describes in general the manufacture of metallic compounds of thiazole derivatives forming alkali salts.

Title: Reversible freewheel clutch mechanism having automatically acting pawl release means
IPC: F16D41/16
Filed: 1968-08-01
Abstract: 1,218,088. Ratchet clutches. HAGELSRUMS MEKANISKA VERKSTAD A.B. 1 Aug., 1968 [27 Dec., 1967], No. 36733/68. Heading F2C. An automatically reversing freewheel clutch mechanism for connection between a driving shaft of a tractor and an input driving shaft of a trailer which is normally rotating faster than the tractor driving shaft, has a reversing ring 13, Fig. 1, which is rotatable through a limited distance to force pawls 12 in one direction or the other into engagement with a ratchet cylinder 10 depending on the rotational direction of the clutch mechanism. The pawls are moved by spring-loaded balls 30 in the ring 13. Since the trailer drive-shaft rotates faster than the tractor output shaft there is normally no drive transmitted by the clutch mechanism, and to prevent the pawls snapping over the ratchet teeth 22 a pawl raising ring 14 is provided. The output hub 6 will normally rotate counterclockwise relative to the pawl cylinder 8 and due to friction taps 37 of the output clutch end portion 9 the pawl raising ring 14 will also tend to rotate counterclockwise relative to the cylinder 8. When the pawls are turned clockwise by the ratchet teeth 22 the ring 14 will rotate to a limited degree so that the slots 36 which allow the pawls to pivot assume a position in which this is not possible, thereby holding the pawls clear of the teeth 22. If the tractor wheels begin to spin the input clutch hub 5 begins to rotate faster than the output hub 6 so that the ring 14 will be rotated clockwise relative to the pawl cylinder 8. This will move the grooves 36 to a position in which the pawls may be pivoted with engagement with the teeth 22. Thus the trailer wheels will be driven until the tractor wheels stop slipping. The device functions in a similar manner if the input is clockwise rather than counter-clockwise.

Abstract: 361,145. Drilling-machines. STAMP. FLI, O., 32, Bleicherstrasse, Zug, Switzerland. Dec. 5, 1930, No. 36803. Convention date, Dec. 11, 1929. [Class 83 (iii).] A tool turret for use with a drilling or like machine is in two parts, one fixed and the other rotatable, the latter part which carries the tool holders being axially displaceable from the former so as to uncouple a tool holder from the driving spindle and permit a fresh tool to be brought into the working position. The fixed part 2, shown fastened to the adjustable sleeve of a drilling- machine, is drilled at 14 to receive a spring-controlled bolt 15 the lower end of which is in the form of a bearing sleeve and carries the spindle 22 of the rotatable tool-carrying turret 23 ; upward movement of the turret awav from the work causes the end of the bolt 15 to strike an arm 4 on the machine and thereby displace the turret part downwards, in a direction parallel to the driving spindle, against the pressure of the spring 16, this movement separates the clutch elements 29, 30 and the centring piece 11 and at the same time a ratchet wheel 36 keyed to the spindle 22 moves over a stop bolt 37 to rotate the turret to the next working position. The stop bolt 37 may be released to enable the feed to be effected by hand. A modi. fication in the ratchet device is described and also a device consisting of a spring-pressed roller coacting with a star wheel to assist in bringing the tools into working position.

Title: Sludge Separator with Automatic Control.
IPC: G01F23/18
Filed: 1967-08-11
Abstract: 1,199,461. Centrifugal saparators. WEST FALIA SEPARATOR A.G. 11 Aug., 1967 [11 Aug., 1966], No. 36894/67. Heading B2P. A sludge centrifuge comprises a control chamber, e.g. 16, located adjacent the axis of the centrifuge drum 1, 2, means for supplying liquid to the control chamber, a conduit, e.g. 17, connecting the control chamber to the sediment chamber 118 and arranged so that material deposited in the sediment chamber can cause variations in the free surface level of the liquid in the control chamber, and a blade wheel 19 arranged in the control chamber and caused to rotate by being immersed when the free surface level of the liquid moves inwards, rotation of the blade wheel being used to trigger a signal to indicate when the sediment chamber has filled up with sludge and/or to actuate controls to initiate the desludging of the drum. The liquid to be centrifuged is fed into the separating chamber through conduits 6, 7, 8 and via a central supply chamber 9 and the purified liquid flows from the central part of the separating chamber through holes 10 into a skimming chamber 11 where it is removed by a skimming disc 12 leading to a discharge line 13. A small portion of the purified liquid is conducted into the control chamber 16 through a channel 15 connected to one of the channels 14 in the skimming disc 12. This liquid can pass from the chamber 16 into the chamber 18 through a number of channels 17. In operation, when the sludge in the chamber 18 reaches a predetermined level, the free liquid level in chamber 16 moves inwards and causes the blade wheel to become immersed and thus rotate. Rotation of the wheel causes a shaft 21, to which it is connected, to operate through rack and pinion a push rod 23 which actuates a switch 24. The latter operates a solenoid valve 25 in a supply line 26 for the control medium which actuates a sliding piston 5 for the discharge of sludge through ejection apertures 4. Alternatively, the shaft 21 carries a plate to which the push rod 23 is eccentrically attached. The switch may be arranged inside the drum. Rotation of the blade wheel may be limited and the wheel may be biased by a spring towards its original position. In a modification, the blade wheel may be arranged in the central entry chamber for the liquid to be purified. In this case, the free liquid level of the liquid to be purified shifts radially inwards when its entry in the separating chamber is impeded by sludge in the sediment chamber outside the separating plates.
