Title: Phosphorus compounds
Inventor: FIELDING HAROLD CROSBIE
IPC: C08G18/77
Filed: 1960-05-11
Abstract: A process for making phosphorus-containing compounds comprises heating a phosphorus containing triurethane derived from an aliphatic alcohol and phosphorus isocyanate or phosphoryl isocyanate, with an organic compound containing one or more reactive hydrogen atoms in hydroxyl or amino groups, the organic compound being less volatile than the alcohol from which the phosphorus-containing urethane is derived.  The organic compound containing one or more reactive hydrogens may be an alcohol, polyol, amine, polyamine, polyester or other polyhydroxy compound, including polyglycerol esters, oxypropylated trimethylol propane, decamethylene diamine and cellulose.  Triethylamine and dibutyltin diacetate are suitable catalysts.  The products can be formed in situ as coatings, films, cast blocks and in fibre-glass reinforced laminates.  In examples there are reacted together (1) phosphoryl triethylurethane and polyglycerol adipate; (2) phosphoryl triethylurethane and decamethylene diamine; (3) phosphoryl triamylurethane and polyglycerol adipate; (4) trimethylphosphoryl urethane and oxypropylated trimethylol propane; (6) phosphorus triamyl urethane and a diethylene glycol pentaerythritol adipate; (7) phosphorus triethyl urethane and a trimethylolpropane/propylene oxide condensate with a tributylamine catalyst (applied as a film to tin plate).  In Example (5) cotton cloth is fire-proofed by treatment with trimethylphosphoryl urethane and a triamylamine catalyst in water (oxypropylated trimethylol propane being an optional ingredient) followed by heating at 140 DEG -150 DEG C.ALSO:Cotton fabric is fire-proofed by heating with a phosphorus-containing tri-urethane derived from an aliphatic alcohol and phosphorus or phosphoryl tri-isocyanate, the hydroxyl groups of the cellulose reacting to form phosphoruscontaining compounds on the surface of the fabric.  In Example 5 cotton cloth is treated with an aqueous solution of trimethylphosphorylurethane, dispersing agent and triamylamine catalyst, dried, and heated at 140 DEG -150 DEG C.  A cross-linking agent, such as oxypropylated trimethylolpropane may also be included in the solution used for the treatment.

Title: Improvements in or relating to a machine having a counter balanced luffing boom structure
IPC: E02F3/26
Filed: 1966-04-18
Abstract: 1,086,075. Counterbalancing apparatus. J. PRADON. April 18, 1966 [April 16, 1965], No. 16874/66. Heading B8B. [Also in Division E1] A machine, e.g. a bucket wheel reclaimer, comprises a support structure 1, a boom structure 2 and a counterbalance structure 5 having a counterweight 4, the boom 2 being luffed by a winch 6 via a cable 3. The end of the cable 3 opposite to that attached to the winch 6 is attached to a counterweight 7 vertically slidable on guides in the support structure 1. In operation the winch 6 winds in the cable 3 whereupon the weight 7 is raised into engagement with stops, after which the boom 2 is lifted. As cable is payed out the boom 2 is lowered until it is directly or indirectly supported on the ground whereupon the weight 7 moves downwardly to tension the cable 3 and support the weight of the boom 2, to maintain the stability of the machine. As the weight 7 is lowered, a cam surface thereon engages first a switch to de-energize the winch motor and secondly, in the case of an accident, a switch which de-energizes the whole machine. In the embodiment of Fig. 4 (not shown) the counterweight on the end of the cable is mounted at the outer end of the counterbalance arm and constitutes part of the main counterbalance weight.

Title: Improved change-speed hub gear for pedal cycles, motor cycles or the like
IPC: B62M11/14
Filed: 1961-05-09
Abstract: 952,902. Change-speed gears. FICHTEL & SACHS A.G. May 9, 1961 [May 27, 1960], No. 16896/61. Heading F2D. A three-speed pedal or motor cycle hub gear comprises a stationary sun gear 12 and a dogtoothed selector sleeve 3 slidable axially in a toothed or slotted driving member 2 fast with a driving sprocket 1 to connect the latter either with a planet carrier 9 to overdrive a ring gear 14, or with the ring gear for direct and reduced drive, the ring gear and planet carrier being selectively clutchable to a single output free-wheel clutch by an axially slidable clutch sleeve 17. In the high gear position shown in Fig. 1, teeth 6 on the manually-operable selector sleeve 3 mesh teeth 7 on the planet carrier 9 which drives the ring gear 14 at a step-up-ratio, the ring gear driving, through meshing teeth 15, 16, the clutch sleeve 17 which is formed as the carrier of pawls 18 of the freewheel clutch which pawls engage ratchet teeth 19 formed on the hub sleeve 20. In the direct drive position, the teeth 6 are disengaged from the teeth 7 and engage teeth 23 on the ring gear, which drives the hub sleeve as before. Further movement of the selector sleeve 3 to the right to its low gear position causes the ends of the teeth 6 to engage a disc 24 fast with the clutch sleeve 17 and shift it to the right, disengaging the teeth 15, 16 and engaging teeth 25 on the planet carrier 9 with teeth 26 on the ring gear. The teeth 6 are long enough to remain meshed with the teeth 23 so that the ring gear is driven and drives the planet carrier at a reduced ratio. The selector sleeve 3 has teeth 4 engaging long teeth 5 in the input member 2 so that it is driven in all its positions, and the ratchet teeth 19, which are formed directly in the hub sleeve or in a member secured thereto, are long enough to engage the pawls 18 in both positions of the clutch sleeve 17. The pawls 18 may be held disengaged from the ratchet teeth 19 during free wheeling as described in Specification 804,533. In the embodiment shown in Fig. 9 the clutch sleeve 35 is axially slidably connected by teeth 36, 39 to an axially fixed driving part 42 of a free-wheel clutch 41, which may be of the wedging roller instead of the pawl-and-ratchet type. A back-pedalling brake 44 is provided, having a braking member 61 in screw-threaded engagement with the planet carrier 37. On back-pedalling the member 61 is screwed to the left and has a conical surface engaging a divided or slotted brake cone 64 which then engages, by way of a brake lining 65, with a brake surface of the hub sleeve 20. In a modification the selector sleeve 3 is replaced by a selector member which is axially slidable in a slotted driving member 2 and which in the high gear position engages with extensions of bearing pins of the planet pinions, and has a set of dog teeth engaging teeth on the ring gear in its direct and reduced drive positions.

In a photo-electric pyrometer, to avoid errors due to temperature variations over the radiating surface and sensitivity variations over the photo-cell surface, an object lens L2 projects an image of the rear surface of the object lens L1 on to the photo-electric cell C. An apertured diaphragm A adjustable by a screw mechanism S serves to limit the area of the radiating surface from which heat rays are received by the cell. The diaphragm is situated at the conjugate focus of the radiating area. The photo-cell may be mounted in a detachable head H which may also contain the measuring equipment. If an alternating output is required from the photo-cell a vibrating reed may be employed as described in Specification 642,697, [Group XL (c)], or a chopping-wheel may be employed this wheel being situated between two diaphragms with aligned apertures. An infra-red filter I is inserted in front of lens Ll or may be inserted directly in front of cell C.
