Patent GB-560094-A (GB)
Title: Improvement in sulfauro compounds and processes for their production
IPC: C01G7/00
Filed: 1942-08-03
Abstract: Organic sulphauro compounds are prepared by reacting a mercapto compound R-SH with aurous cyanide or an alkali aurocyanide.  R p  may be a substituted or unsubstituted alkyl or aryl radical.  In examples (1) an aqueous solution of thiomalic acid is added to an aqueous suspension of aurous cyanide and heated on the steam bath. The product is evaporated and triturated with hot ethyl acetate to give pure auro-thiomalic acid.  (2) A solution of gold chloride is added to a solution of sodium bisulphite, potassium hydroxide and potassium cyanide in water and the product added to cysteine hydrochloride to give aurocysteine.  (3) An aqueous suspension of aurous cyanide is added to p-acetamino-thiophenol to give p-sulphauro-acetanilide.  (4) An alcoholic solution of cetyl mercaptan is treated with active aurous cyanide to form cetyl auromercaptan.  The aurous cyanide is prepared in a form suitable for use in the present invention by pouring one mol of reagent gold chloride slowly with stirring into a solution prepared by dissolving 4 mols. sodium hydroxide, one mol. sodium bisulphite and two mols. sodium cyanide in the above order. The mixture is heated on the steam for 1/2 hour and then an equal volume of concentrated hydrochloric acid added.  Heating is continued for one hour to form a yellow precipitate of aurous cyanide.

In closing (from the dotted position shown), the members 1, 9 are the first to engage.
Patent GB-109450-A (GB)
IPC: E05B37/00
Abstract: 109,450. Mace, J. Sept. 6, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Locks, permutation.-The permutation mechanism is carried by a circular member 3 to which a definite sequence of rotary and up and down movements are given by the knob 33 before the bolt 47 can be drawn back. The permutation elements are carried by rings 2 mounted on the member 3, and the combination is changed by removing these elements and substituting others of different length. The rings 2 are held in position by friction and failure to make the movements forming the combination results in displacement of one of them. Following upon this, the mechanism must be brought back to the starting position by turning the knob 33 backwards.

Title: Low frequency generator
IPC: H02K27/20
Filed: 1947-04-25
Abstract: 658,732. A.C. commutator machines. IGRANIC ELECTRIC CO., Ltd. April 25, 1947, No. 11125. Convention date, April 27, 1946. [Class 35] A commutator machine is made to yield low frequency A.C. by causing its field, which is fed from the output of the system, to oscillate. As shown for a single machine yielding single - phase current at L1, L2, the field coils 2 are connected in series with a suitable condenser 3 to produce the correct frequency of oscillation across the armature 1. A normally closed relay 5 is energized through a rectifier 6 from the machine brushes and serves to shortcircuit the condenser at starting until the machine has built up to a suitable voltage to start oscillating, and also at stopping, to short-circuit the condenser and prevent the dying oscillation destroying the residual flux of the machine. In a two-phase arrangement (not shown) the fields of two mechanically coupled commutator generators are fed from one of the machines through resistances and condensers of suitable values to produce the necessary phase displacement in the two field windings. Alternatively, each field may be fed from the armature of the other machine. A three-phase arrangement comprises three mechanically coupled machines, each field of which is excited from the armature of the next machine through a condenser and resistance giving a phase displacement of 120 degrees. Compensating windings or split poles may be used to reduce the effect of armature reaction.

Abstract: 792,523. Rolling. SCHLOEMANN AKT. GES. April 13, 1956 [April 18, 1955], No. 11277/56. Class 83 (4). In a four high-rolling mill in which the working rolls 1a, Fig. 1, are offset from the plane of the backing rolls 3a they are supported against rollers 8 on the backing roll housings 6a, by pressure pieces 11a attached to actuating levers 16 on pivots 15 in the backing roll housings 6a. The bolts 13 by which the pressure pieces 11a are attached to the levers 16 lie within the vertex opposite the axes of the backing rolls 3a and supporting rollers 8 so that the working rolls 1a are held in engagement. The levers 16 are actuated by a toggle mechanism 20, 21 which is operated by rotation of a shaft 23 carrying a hexagon nut 22 (not shown), and comprises one arm 21 with an adjusting screw-thread 18 so that the position of the pressure pieces 11a can be preset. In another example the pressure pieces 11b, Fig. 3, are pivoted on arms 26 which are slidably mounted on the backing roll housings 6b and are pressed towards the rolls by fluid-operated cylinders 32 having non-return valves to maintain the pressure pieces 11b rigidly in position. The arms 26 are pivoted on bolts 28 which are slidable along slots 29 in brackets 27 attached to the housings 6b and having set screws 30 to limit the movement. In this example intermediate rolls 36 are mounted between the supporting rollers 38 and the working rolls 1b and the supporting rollers 38 are maintained in driving contact with the backing rolls 3b so that an additional friction drive is transmitted to the working rolls 1b. The supporting rollers 38 are mounted on vertically slidable carriers 47 to which pressure is transmitted from fluid-operated cylinders 54 through levers 52 and links 50. The bearings 40 of the intermediate rolls 36 are freely slidable in grooves 41 in arms 43 which are pivoted to the shaft 42 of the supporting rollers 38. Alignment of the arms 43 and intermediate rolls 36 with the working rolls 1b is maintained by pressure pieces 44 on the arms 43 which are actuated by fluid pressure cylinders 46 and engage the bearings 35 of the working rolls.

Abstract: 819,486. Variable-speed gearing. ATELIERS G.S.P. GUILLEMIN, SERGOT, PEGARD. April 16, 1956 [April 15, 1955], No. 11491/56. Class 80 (2). A variable horizontal feed movement is imparted to the table 8 of, for example, a shaping machine, which is itself on a carriage 13 vertically movable on the machine, by means of a chain 25, Fig. 4, anchored at one end at 32 and at the other end to a spring 25a. This chain is given a reciprocatory movement by a sprocket 30 mounted upon a continuously rotating eccentric 6a and imparts an oscillatory motion to an idler sprocket 35 and the pawl carrier 41 of a one-way clutch device C mounted on the carriage 13. The driven member 46 of the one-way clutch drives the feed screw 9 of the table 8 through suitable gearing. The feed rate is controlled by a mask for the ratchet pawl 42 which is controlled by means of another chain 50 passing around and anchored to a freely mounted sprocket 52 and anchored at its other end to a spring 51. A projection on sprocket 52 engages through a ball 55 on abutment screw 56 which controls the position of sprocket 52 and hence that of the mask for pawl 42. The arrangement allows for vertical movement of the carriage 13 without affecting the relative positions of the mask and pawl. In a modified arrangement a friction ratchet clutch is employed and its effective stroke controlled by anchoring one end of the oscillatory chain to a pivoted lever with a roller which is adjustable relative to a drum on the driving eccentric. While the roller is clear of said drum the oscillatory chain is driven as before but when the drum engages the roller the lever is moved to compensate for movement of the chain and reduce the amplitude of oscillation imparted to the ratchet clutch.
