Title: Improvements in the Rolling of Metal Billets
IPC: B21H7/10
Filed: 1967-08-15
Abstract: 1,179,346. Rolling. ROTARY PROFILE ANSTALT. 15 Aug., 1967 [22 Aug., 1966], No. 37503/67. Heading B3M. A billet rolling mill includes series of rollers defining the walls of an elongated throat of decreasing cross-sectional area through which a billet is rolled, at least one series of rollers consisting of an endless line of orbiting spaced rollers. Lateral, as well as vertical, expansion of a billet in the throat is controlled by the rollers. Series 27 and 29 of rollers, Fig. 7, act on opposed faces of a billet 16, the rollers being intercalated to enable a very small final throat cross-section to be obtained. Supports or rolls 10 can be used for both series of rollers. Backing rolls for the individual rollers may be provided, and the rollers can have concave, as opposed to cylindrical, surfaces. I-Beams or similar sections 16, Fig. 2, can be rolled by series 20, 22, 24 and 26 of rollers, or by only two or three series of suitably profiled rollers (Figs. 4-6, not shown). The orbitally movable rollers of each series can conveniently be mounted on a driven chain.

Abstract: 836,232. Spray producers. GRACE & CO., W. R. April 23, 1957 [April 27, 1956], No. 37972/58. Divided out of 836,231. Class 69 (3). A nozzle for applying a liquid gasket compound to a workpiece comprises a chamber 116, Fig. 3, adapted to receive the compound, a shaft 122 projecting from the chamber 116 and having an axial bore 123 communicating with the chamber 116, a rotatable nozzle cap 136 journalled on the shaft 122 and having passages 137, 138 communicating with the bore 123, nozzle tips 143, 144 fixed to the cap 136 and each having a capillary bore 142 communicating with the passages 137, 138, power means to rotate the cap 136, a valve 125 for closing the bore 123, and valve-actuating mechanism, e.g. an electro-pneumatic actuator 115. The shaft 122 is threaded on to the bottom plate 121 of the chamber 116 and supports by a nut 131 two radial ball-races 126, 127 housed respectively in bearing cages 128, 129, the cage 129 supporting the cap 136. A gear 146, driven by a motor (not shown), is fixed to the cage 129 to rotate the cap 136. Compound enters the chamber 116 at 117, a rubber diaphragm bonded to the needle valve 124 preventing access of compound to the actuator 115, and flows via the bore 123 and passages 137, 138 to the bores 142, the valve 125 being periodically opened by the actuator, e.g. as described in Specification 836,231. A packing 133 and rings 134, 135 prevent compound entering the bearings 128, 129. Replaceable plugs 139, 141 in the passage 138, which is transverse of the cap 136, enable air to be vented from the apparatus on starting operation. Two, three or more tips 143, 144 may be employed. The bores 142 of the tips 143, 144 and portions 145 which enter the cap 136, may be axially located relative to the tip, or the bores may be slightly inclined as shown, and the portions 145 may be eccentric with respect to the axis of the tip, also as shown, thus permitting adjustment of the radius of rotation of the tips to suit different workpieces. In a modification, Fig. 2, the nozzle cap 57 is threaded on a split nut 58 which engages a channel 61 in the shaft 47, the cap 57 having a driven gear 66. Tips 65, e.g. three in number, are axially adjustable in the cap 57 to vary their radius of rotation.

Title: Improvements in and relating to glycols
Inventor: STEEL DEREK KENNETH VINCENT
IPC: C07C31/18
Filed: 1960-11-09
Abstract: A substantially smell-free glycol is produced by a process comprising distilling the glycol in a distillation column throughout which an inert atmosphere is maintained by an inert vapour during the distillation of the glycol, the volatile impurities being carried overhead with the inert vapour and the glycol being recovered as a side-stream below.  Suitable inert vapours are, for example, steam and nitrogen.  When steam is used to provide the inert vapour it may be admitted into the boiler as water either with the crude glycol vapour or separately.  When steam is used as the inert vapour the glycol product may contain a little water and this may be removed by treating the product with dehydrating agents or by a further distillation according to the invention using a dry inert gas.  The process may be carried out batchwise or continuously and the boiler contents are preferably maintained in a slightly alkaline condition by the addition of an inorganic base, such as sodium hydroxide or an organic base, particularly an amine with antioxidant properties such as NN1-di-sec-butyl-p-phenylene diamine.  Examples are given of the purification of propylene glycol, and dipropylene glycol.

Abstract: 1,076,645. Electric selective signalling. CARL ZEISS JENA VEB. Sept. 29, 1964, No. 39652/64. Heading G4H. The lowest order of a coded-pattern (15<SP>11</SP>) position digitizer is interpolated by casting an optical image of a non-coded scale (15<SP>1</SP>) moving with the coded pattern (15<SP>11</SP>) on to a continuously moving member (8) which bears a non-coded scale (13) to produce clock pulses, and also bears two further marks (12, 14). The clock pulses are counted by a counter which is zeroized by detection of one of said marks (14). The other mark (12) is spiral and when the image referred to coincides with a part of it a pulse is produced which gates the momentary counter reading to a store. The store contents constitute a fine part of the system output, and the highest order of the store selects a leading or lagging sensing head in the lowest order of the coded pattern. The coded pattern, which has U-scan or V-scan operation throughout, provides the coarse part of the system output.
