Title: A gooseneck for die casting machines
IPC: B22D17/06
Filed: 1963-05-21
Abstract: 967,707. Die-casting machines. PLASCO Ltd. May 21, 1963 [June 18, 1962], No. 20094/63. Heading B3F. The gooseneck in a die-casting machine comprises a neck portion 17 and an upwardly extending sleeve or stem 34. One end of the neck carries a nozzle 19 which is aligned with the gate 24 of the die 21. The other end of the neck is attached to the lower end of the stem 34 wherein is located a titanium diboride bush 26. The bush has a chamber 28 and a seating 30 for the end 31 of an operating rod 37 located coaxially and slidable within the sleeve. To the upper end of the stem is secured a bracket 43 with a pivot 44 to permit movement of the gooseneck to break contact between the die and the nozzle after the discharge of molten metal. The bracket 43 houses a pinion 47 which engages rack teeth 48 on the stem to facilitate alignment of the nozzle and die. The bracket also includes a cylinder 52 and piston 53 which engages the spherical head 41 of operating rod 37 to urge the rod end 31 on to the seating 30 against the action of the spring 42. The discharge of molten metal into the die is effected by a compressed air system, which includes an accumulator 60, and whereby the sequential operation of valves 59, 69 to 73 effects discharge of metal into the die and actuates the piston 52 to reciprocate the rod 37. The control of the valve operations maintains the desired levels of molten metal in the machine and also effects a " suck back," such that after the metal is discharged into the die and the gooseneck pivots about 44 there can be no metal drip from the nozzle. The size of the air accumulator may be adjusted in relation to the quantity of molten metal required for a given casting. The operating rod is formed in two parts, the lower portion being of titanium diboride which abuts the upper portion and is secured thereto by a braised joint. In an alternative embodiment, the upper portion of the rod is threaded and the lower portion is attached thereto by a sleeve nut.

Title: Process for the manufacture of new yellow acid sulphuric acid esters of leuco derivatives of vat dyestuffs
IPC: C09B9/02
Filed: 1933-07-18
Abstract: Phthaloylfluoranthenes are converted into their leuco acid sulphuric esters or the stable salts thereof according to known methods.  The starting materials are obtained by reacting fluoranthene or its substitution products with phthalic anhydride or a substitution product and ring-closing the products after further substitution if desired (cf. Specification 378,476).  In examples: (1) dry leuco phthaloylfluoranthene is heated with a mixture of pyridine and chlorsulphonic acid in a current of carbonic acid; the ester on treatment with a mineral acid and a weak oxidizing agent gives a greenish-yellow precipitate; (2) similar treatment of bromophthaloylfluoranthene (obtained by bromination) gives the corresponding ester and bromo derivative obtained by brominating 12-fluoranthenoyl - o - benzoic acid, separating isomers via their sodium salts, and ring-closing by means of sulphuric acid may be similarly converted; (3) phthaloylfluoranthene is heated with copper, pyridine and chlorsulphonic acid in a current of carbonic acid to give the leuco sulphuric ester.  These esters yield strong shades of yellow when dyed or printed on textile fibres and developed.

To avoid jamming of a warped pallet against the plate 1 the latter is mounted on a spring suspension including springs 3 mounted on rods 2 which are pivoted at 4 on a horizontal axis in line with a block of bricks on the plate.
Patent GB-486488-A (GB)
Title: Recovery of lower aliphatic acids
Filed: 1937-07-23
Abstract: Lower aliphatic acids are recovered from solutions thereof containing also dissolved and/or suspended cellulose derivatives by heating the solutions to a temperature above their boiling point at normal atmospheric pressure so as to convert the cellulose compounds into water - soluble substances.  Temperatures of from 160 to 200 DEG  C. are suitable.  Strong mineral acids if present may be neutralized before the treatment.  After the hydrolysis is complete, the cellulose compounds all being converted to water-soluble substances, the acids are extracted in counter-current with solvents such as ethyl ether, isopropyl ether, propyl, butyl or amyl acetate, methyl isopropyl ketone, propylene chloride, ethylene chloride, methylene chloride, isopropyl iodide.  Examples describe the recovery of acids from the manufacture of cellulose acetate and cellulose acetopropionate.  Treatment of cellulose butyrate residual liquors is also mentioned.  Specifications 266,684 and 284,685, [both in Class 2 (iii)], are referred to.

There are also provided three accelerometers 1, 2, 3 which determine the angular acceleration of the vehicle with respect to its centre of gravity from which the high frequency components of α, #, γ can be found using high pass filters 4, 5, 6 and a computing circuit 7, the components and functions of which are shown in Fig. 1. The high and low frequency components are combined in adders at the riaht-hand side of Fig. 1 to give the angles α, #, γ. Figs. 3 and 4 (not shown) illustrate more practical systems utilizing the same principles as Fig. 1. Thus the highpass filters 4, 5, 6, and the integrators 9, 10, 14, 15, 20, 21 are associated together in respective negative feedback systems for each channel x, y, z to take care of the initial conditions of the integrators. It is also shown that the high and low pass filters can be replaced by single circuits to ensure that the high and low pass characteristics are exactly complementary.

Title: Improvements in or relating to gear cutting machines
IPC: B23F23/00
Filed: 1928-07-19
Abstract: 310.721. Moss Gear Co., Ltd., and Gregory, E. July 19, 1928. Gear-cutting.-In a gear cutting machine particularly for cutting multiple-threaded worms the work-spindle 3 is connected with a setting mechanism whereby the work may be returned for successive cutting operations to a previously set position. The shaft 3 carries a loose worm whee.l 5 rotated from a hand-wheel 8 and carrying a spring-pressed detent 10 which coacts with a series of notches 9<a> in a disc 9 keyed to the work-spindle. A looking plate 12 has a single notch 12a which may be registered with any one of the notches 9a by means of a bolt 13 passing through a hole in the locking-plate and engageable with one of a series of threaded holes in the disc 9. In operation, the spindle 3 is rotated to bring the work into the desired relation with the tool and the worm-wheel 5 is then turned to bring the detent into engagement with one of the notches and the locking-plate is secured with its notch also engaging the detent. On rotation of the work, the locking-plate prevents the detent from dropping into any other notch in the plate and the work may be at any time reset to its original position by turning the work-spindle until the detent again engages the selected notch.
