Title: Improvement in treatment of rubber
IPC: C08K5/00
Filed: 1938-05-13
Abstract: Tetra-amyl thiuram monosulphide is prepared by treating an aqueous alkaline solution of diamylamine at 30 DEG  C. with carbon disulphide to yield a solution of diamyl-dithiocarbamate, which is diluted with water and treated with phosgene at 35-40 DEG  C. until an acid test is obtained with litmus.  The reaction product is separated with benzene, which is distilled off at low pressure and a maximum temperature of 110 DEG  C.  Tetra-alkyl thiuram disulphides containing more than four carbon atoms in each alkyl group are prepared similarly to the corresponding ethyl and methyl compounds. Tetraamyl tetrahexyl-, tetraheptyl- and tetraoctylthiuram disulphides are specified.ALSO:A vulcanization accelerator consists of a tetraalkyl thiuramsulphide in which each alkyl group contains more than four carbon atoms in the open chain.  The preferred material is tetra amyl thiuram monosulphide.  This may be prepared by dissolving 15,6 pts. of caustic soda in 234 lb. of water, adding 60 lb. of diamyl amine, bringing the mixture to 30 DEG  C., adding 29,4 of carbon disulphide at such a rate as to maintain the temperature at 30-40 DEG  C.  The solution of sodium diamyl dithiocarbamate is diluted with 300 lb. of water and heated with 22 lb. of phosgene at 35-40 DEG  C. for 3-4 hours.  The reaction product is separated with benzol, which is then distilled off at low pressure and a maximum temperature of 110 DEG  C.  The unpurified product, believed to contain amylated thiourea and amylated urea is preferred as an accelerator, as there is less tendency to scorch.  The higher sulphides will vulcanize without added sulphur.  Corresponding tetra alkyl thiuram disulphides are prepared similarly to tetra methyl and ethyl thiuram disulphides.

Title: Device for indicating the position of the platform in cranes with articulated booms, especially camera cranes
IPC: G03B17/56
Filed: 1966-03-31
Abstract: 1,130,719. Camera supports; fluid-pressure servomotor systems. ROUMANIA STATE BOARD FOR CULTURE and ART. March 31, 1966 [April 1, 1965 (2)], No.14296/66. Headings G2J and G3P. A device for indicating the position of the platform in cranes, such as camera cranes, having a pair of articulated booms comprises a mechanical arrangement for resolving the movements of each boom into its vertical and horizontal components, and separately adding them. As shown a parallelogram linkage 1, 2, 3, Fig. 1 is so fixed to the upper boom that link 3 is parallel thereto and, through a slide mechanism, the indicator 5 moves a distance proportional to the vertical displacement of the upper boom. A shaft 6 fixed to the lower boom along its lower pivotal axis moves, through lever 7, pin 8 and groove 9, a cylinder 10, which is slidable on a shaft 11, so that by reading indicator 5 against a scale on cylinder 10 the full vertical displacement of the camera platform is indicated. Similarly horizontal movement of the upper boom is transmitted by the parallelogram linkage, hollow shaft 12, lever 23 and rod 14 to an indicator a and that of the lower boom through shaft 6 and lever 15 to a graduated rule 16 co-operating with indicator a. Rotation of the crane is measured by indicator 5 against the cylinder 10 which is rotated by key and slot connection b whenever shaft 11 is rotated through belt 18 and pulley 19 from the pulley 17 fixed to the crane. To enable the camera platform to move vertically without horizontal movement, a hydraulic valve (21), Fig. 3 (not shown), is connected to rod (14) and a piston (22) to rule (16) the arrangement being such that when the lower boom is moved by a hydraulic cylinder, if the platform moves horizontally there will be differential movement of piston (22) and valve (21) and this is used to control a hydraulic cylinder (20) connected between the two booms so as to eliminate such horizontal movement and thus restore the initial relationship between piston (22) and valve (21). Alternatively a similar arrangement may be associated with indicator 5 and cylinder 10 so that the camera platform is moved horizontally without veritcal movement.

Title: Improvements in and relating to the application of finely divided material
Inventor: FOWLER FRANK
IPC: A61M11/00
Filed: 1958-05-06
Abstract: 898,649. Respiratory appliances. BENGER LABORATORIES Ltd. April 15, 1959 [May 6, 1958; Nov. 28, 1958], Nos. 14396/58 and 38476/58. Class 81 (2). A powder dispenser for treating the respiratory organs has a valve controlling the injection of powder which can only be opened on inhalation. The powder is contained in a cylindrical capsule having holes for the passage of air through it and this is placed in a chamber 17 in the body 12. The walls of this chamber are grooved, as at 18, so that only a small proportion of the air blown from a bulb 10 passes through the capsule while the remainder rejoins this at the top of the capsule and causes turbulence and uniform distribution. The exit orifice 30 from the chamber 17 is normally closed by a resilient seal 45 in a piston 35, but when the user applies inhalation suction to the outlet 32, air entering a series of holes 31 raises the piston and allows the powderladen air to escape and travel through orifices 44 into the respiratory passages. Pressure on the bulb 10 alone is insufficient to raise the piston and open the valve, but, if the pressure is applied and the user then inhales, the powder is carried by the initial flow of air to the deepest recesses of the lung. The piston is preferably formed with a rim 42 so that only the lower surface of this rim is initially effective in raising the piston. This forces the user to make a strong inspiratory effort which ensures a relatively large rush of air immediately the valve opens. The valve may be held down by a light spring 46 so that the device need not always be held vertical. A simpler construction is described with reference to Fig. 6 (not shown).

Title: Aircraft alighting gear
Inventor: PITT ANGUS RAYFIELD
IPC: B64C25/20
Filed: 1960-04-26
Abstract: 914,582. Aircraft undercarriages. DOWTY ROTOL Ltd. April 25, 1961 [April 26, 1960], No. 14601/60. Class 4. An aircraft undercarriage includes a leg 1 hinged to the aircraft structure 5 on a pivot 3 to pivot between extended and retracted positions, a lever 15 pivoted to the leg on pivot 16 parallel to pivot 3, a retraction jack (the rod of which is shown at 12) connected to the lever at 13, an abutment e.g. a roller 27 fixed to the aircraft structure 5, the lever co-operating with the abutment during the initial part of the retraction movement so that the jack turns the lever in the same sense as and at a greater angular rate than the leg, and a stop 25 on the leg so that during subsequent retraction, the lever forms a fixed retraction arm on the leg. As described, the jack is pivoted to the aircraft structure at a point (not shown) above pivot 3. Stops 24, 25 limit rotation of the lever 15 relatively to the leg. A down lock comprises a spring biased pin 8 adapted to enter a bore 7 in the leg and withdrawable by a link 11 connected to a bell crank lever 19 pivoted on pivot 3 at 21 and having a roller 23. Lever 15 has a cam face 26 adapted to contact rollers 23 and 27. In the extended position shown in full lines, lever 15 abuts stop 24. Contraction of the jack first rotates lever 15 clockwise, and cam face 26 displaces roller 23 to withdraw pin 8 from bore 7 and unlock the leg. Cam face 26 then abuts roller 27, so that further contraction of the jack rotates pivot 16, and the leg, about pivot 3, as shown in broken lines. During further contraction, lever 15 abuts stop 25 and leaves roller 27, and is effectively rigid with the leg, until the axis of rod 12 is aligned with pivot 16, when the lever 15 acts as a tension link between the rod and the leg, Fig. 2 (not shown), being located between stops 24 and 25. For extension, the jack is extended,which may first release a known up-lock in known manner. The leg falls under its own weight at a rate which may be limited by known means, and when stop 25 contacts lever 15, assists in extending the jack. Towards the end of the extension movement, lever 15 contacts roller 23 and withdraws the pin 8. The leg is then fully extended by wind drag. Thereafter, the jack extends further, and rotates lever 15 to free roller 23, and pin 8 enters bore 7. The above construction enables the pivotal movement of the leg during retraction to be considerably greater than 90 degrees, while avoiding small movements due to the jack axis being close to the leg pivot 3. According to the Provisional Specification, when the leg will not fall under its own weight due to some defect at pivot 3, the jack rod 12 rotates lever 15 to abut stop 24 and causes extension. In this case, pin 8 is not withdrawn by lever 15 contacting roller 23, and the pin is contoured to be displaceable by the leg part 6 near bore 7 to effect automatic engagement of the pin and bore.

Abstract: 402,115. Capsuling bottles. ENOCH, A. G., Dutch House, Raglan Gardens, Wembley Park, Middlesex. May 25, 1932, No. 14806. [Class 125 (ii).] An apparatus for applying thin metallic capsules over the beaded edges of milk-bottles &c., and of the suction type, comprises a tubular magazine b for cap-pieces and a stationary capping head a. A suction nozzle t' withdraws and transfers the caps from the magazine and the capping head and deposits them in a holder u from which they are ejected on to the bottles by a plunger s. A second suction nozzle t may be provided in the holder u. The invention may be applied to a rotary or to a stationary capping machine. The plunger s is carried against a spring r. Bottles A are raised through a forming ring gg and the capsules B are compressed by a resilient ring q. The holder u is slotted to allow passage of the traversing arm ag and the compressible ring q may be replaced by a forming ring having a tightening wire, fingers &c. for moulding the capsule to the bottle neck. As a bottle rises it raises the plunger s and the suction connection dg which operates the valve db through levers dh, dj until the lever dk falls into a slot in the suction valve and prevents its return until the bottle descends. While the valve is in this position the connection df communicates with the suction line through the connections dd and the feeder arm moves a blank from the magazine to the holder. The suction required to feed a fresh cap only comes into operation when the plunger s is raised by a bottle. Suction is also provided at the nozzle t<1> to hold the cap over the bottle during the capping operation. The cap-pieces may be raised against the top of the magazine by a spring to facilitate removal, or they may descend gravitationally to the bottom and be removed thereat. Means may be provided for damping or applying adhesive to the bottle necks before capping. The suction nozzles may have flexible lips and supporting projections for maintaining the cap pieces flat. Heat may be applied by electrical or other means to the clamping or crimping devices for the capsules.
