Title: Methods for improving the stability of threads and like products of polydiene-sulphur dioxide compounds
Inventor: CARPENTER ALBERT STANLEY
IPC: D01F6/24
Filed: 1950-03-17
Abstract: The stability of threads and like filamentary products of polydiene-sulphur dioxide compounds is improved by incorporating in the product one or more aromatic hydroxy compounds, such as pyrogallol, quinol, catechol and b -naphthol.  Mixtures of such compounds may be used, but it is preferred to use one or more of said compounds in conjunction with one or more of the stabilizing agents described in Specification 666,640, i.e. compounds containing the group <FORM:0684967/IV (a)/1> such as hexamine, triethanolamine, urea and thiourea and their N,N- or N,N1-diphenyl derivatives, and the corresponding diphenyl guanidines.  The threads may be first washed, e.g. with methanol to remove any sulphuric acid and are then immersed in solutions of the compounds, preferably in methanol, e.g. of 0.5 to 5 per cent total concentrations, and for times such as 16 hours at 20 DEG  C.  The threads are then removed from the bath and air-dried. Specifications 527,075, 616,276 and 679,274 also are referred to.ALSO:The stability of threads and like filamentary products of polydiene-sulphur dioxide compounds is improved by incorporating in the product one or more aromatic hydroxy compounds, such as pyrogallol, quinol, catechol, and betanaphthol.

A dual power brake system (Fig. 1, not shown) comprises an intensifier cylinder 12 housing first and second intensifying chambers 28, 30 between an end wall of the cylinder and a first intensifying piston 27 and the first intensifying piston and a second intensifying piston 29. A vacuum suspended servomotor divided into a first servo-unit 19 and a second servo-unit 20 is mounted adjacent the second piston 29 and each unit is provided with a reciprocating member 44, 45, the members having movement along a common axis. An intensifying piston extension 54 is disposed along the common axis and is coupled to the second piston 29 and the reciprocating members 44, 45 are engaged with the extension 54 in such a way that either member can push the extension independently of the movement of the other reciprocating member. In the construction shown the reciprocating member 45 directly engages the extension 54 whereas the reciprocating member 44 is provided with a push-rod 58 which slidably passes through member 45 to enter a bore 59 in the extension 54. The movements of the pistons 27 29 are limited by stop means 33, 34, 35 and 36, 37, 38. The members 44, 45 may comprise diaphragms. Each servo-unit is controlled by a toggle valve (Fig. 3, not shown), which in turn is controlled by hydraulic pressure from a master cylinder (Fig. 1, not shown). A chamber in each valve is connected to a chamber of the intensifier and when the circuits are working normally the chamber of each valve is sealed by a pair of valves. Should, however, the servomotor fail, hydraulic fluid can pass from the master cylinder circuit into the chambers of the valves to actuate directly the brakes.

Title: Process for improving the properties of rubber latex
IPC: C08K3/00
Filed: 1934-03-06
Abstract: Dark coloration of latices is prevented or removed, and their stability is increased by treatment with alkaline stabilizers, and small amounts of zinc compounds such as zinc oxide, alkali zincates, zinc ammonium compounds, or salts such as the carbonate, chloride, or acetate.  The quantity of zinc oxide added is 0,01-2 per cent of the rubber, or equivalent amounts of other compounds.  Concentration of the latex may take place before or after the additions.  According to an example, 2,5 kg. of zinc oxide are made into a paste and added to 18,2 kg. of potassium hydroxide in its own weight of water.  This is added to 5000 kg. of latex of 38 per cent solid content, to which has been added 30 kg. of potash-coconut oil soap.  This is concentrated to 75 per cent solids as described in Specifications 382,235 and 393,732 to yield a pale coloured concentrate.  The treatment also retards putrefaction.

Title: Improvements in or relating to machine tools, for example, milling machines
Inventor: LAPPE WILHELM
IPC: B23C9/00
Filed: 1956-03-07
Abstract: 793,218. Milling. WERNER AKT.-GES., F. March 7, 1956, No. 7166/56. Class 83 (3). [Also in Group XXXVII] In a machine-tool mechanism for controlling an automatic cycle of relative movement of a work-table 9 and a tool, in at least two directions, comprises abutments 4-8 carried by the table or tool-slide to actuate switches 1-3 in an electrical control-circuit, the change of movement from one direction to another being effected through a control-drum 12 rotated step-by-step by a controlling-magnet 31 upon each interruption of feed, and the drum having adjustable control-pins 13 to actuate switches in the control-circuit to initiate movement of the table or tool in the required direction. To control the longitudinal movement of the table 9 in a milling-machine, the plunger-switches 1- 3 are actuated through levers 10, 11 by the adjustable dogs 4-8, similar switches and dogs being provided for the cross-slide and knee. The dogs 4, 5 operate when the slide moves left, and the dogs 6, 7 when it moves right. Actuation of the switch 2 by the dog 4 interrupts left rapid-traverse, and further actuation by the dog 5 interrupts left-feed. Similarly, the dogs 6, 7 control the right-movement switch 3. The abutment 8 controls a rapid-traverse switch 1. When feed is interrupted, the drum, which is removably attached to a flange 25, is rotated a single step so that one of a number of screw-adjusted plungers 13 actuates one of a number of switches 16-22 through a lever 23. The switches 16, 17 initiate right and left rapid - traverse for longitudinal traverse; switches 18, 19 forwards and backwards crosstraverse, and switches 20, 21 up-and-down movement. The drum is advanced by a pawl 30 actuated by the magnet 31, which is deenergized after each movement by a switch 32. In each rest-position, a switch 33 is actuated, but this is not effective until the switch 22 has been actuated by a pin 13 at the end of a cycle. The ratchet then operates continuously until the drum has returned to its initial position, when the switch 33 is opened. Further switches may be provided to control movement of a tool, and the pins 13 may also operate switches to initiate feed, instead of rapid traverse-movement.

Title: Improvements in motor vehicle trailers with four steering wheels
IPC: B62D13/04
Filed: 1939-03-07
Abstract: 526,051. Steering trailer vehicles. VIBERTI, C. March 7, 1939, No. 7395. [Class 79 (v)] In a trailer having four steerable wheels, the steering mechanisms 12 at the ends are connected by rods 14 to arms 15 on cross-shafts 16a, 16b, coupled or un-coupled by a clutch 17 controlled by a hand lever 18 so that all four wheels are steered together or one pair can be steered independently of the other, the clutch, if left open, being closed automatically as soon as the drawbar is pulled. The stub axlearms 5 of each pair of wheels are connected together by the usual track rod 6 and one stub axle of each pair has an arm 11 connected by a rod 13 to a lever 12 pivoted at 12a and operated by the drawbar 29 through a detachable fork 30. Normally the steering gears at each end are connected together by the clutch 17 which is closed by a spring 19. When it is desired to steer only one pair of wheels the clutch 17 is disconnected by means of the hand lever 18. The hand lever engages cam teeth 20 to hold the clutch disengaged. If, however, either drawbar 29 is pulled, a spring 28, Fig. 5, on an extension 27 is compressed and allows a weak spring (not shown) to draw an arm 25 forwardly and re-engage the clutch 17, the arms 25 being connected by cables 24 to arms 23 on the shaft of the hand lever 18. When the clutch 17 is disengaged that pair of wheels which is not connected to its drawbar is then kept in the straight-ahead position by means of a centring spring 7 on the corresponding track-rod 6. Sockets 8 for the spring bear against stops on the rod, and also against sleeves 9 which are anchored in a central position by links 10, so that the spring is compressed whichever way the rod 6 moves and thus tends to keep the rod and wheels centred.
