Abstract: 791,662. Change-speed gear. BROWN & SONS (HUDDERSFIELD) Ltd., D. Sept. 24, 1956 [June 23, 1955], No. 18140/55. Class 80 (2). A gear ratio selecting and establishing mechanism, for a main changespeed gear in series with an auxiliary change-speed gear, comprises a shift lever (not shown) movable through a series of successive positions to cause step-by-step rotation of two drums c, d provided with cam grooves n, g, the cam groove g operating selector rods h, j, k, m controlling the main change-speed gear and the cam groove n operating a selector rod s controlling the auxiliary change-speed gear. The shift lever may be connected to a toothed segment a meshing a gear b fast with the drum c, another gear e fast with the drum c meshing a gear f fast with the drum d. The ratio between the gears e, f is 2:1. The shapes of the cam grooves n, g and the ratio between the gears e, f are so arranged that a complete revolution of the drum d takes place with corresponding movement of the selector rods h, j, k, m to establish all the ratios in the main change-speed gear while the drum c performs half a revolution and the selector rod o remains still so that the ratio in the auxiliary gear remains unchanged. Further movement of the shift lever then moves the selector rod o to its second position and then recommences the engagement of the ratios in the main change-speed gear while maintaining the auxiliary gear in its new ratio. As a modification, the shift lever may be secured directly to the gear b.

Title: Controlling the withdrawal of heat in continuous casting moulds
IPC: B22D11/22
Filed: 1973-04-17
Abstract: 1409947 Automatic control of temperature CONCAST AG 17 April 1973 [18 April 1972] 18496/73 Heading G3R [Also in Division B3] In an arrangement for controlling the withdrawal of heat during the continuous casting of metals in mould 1 (Fig.1) having cooling regions 7, 8, 9, 10 through which cooling fluid is passed, in order to ensure uniform contact of the surface or skin of metal being cast with the mould walls, instruments 14, 15 connected respectively across the cooling fluid (water) inflow and outflow conduits 12 for the narrow walls 4, 5, measure the quantity of heat withdrawn per unit time as a measure of the degree of contact between the metal skin and walls. The measured values are compared with respective desired reference values thereof in a comparator 22 of a regulator 20. The reference values are delivered by a device 23 which receives momentary reference values from the computer 30. The resulting difference value is applied via a function generator 21 to adjust the [cooling fluid] through flow-rate of fluid in the cooling chambers or regions 7, 8 of the wide walls 2, 3 by means of elements 16 to 19 until the heat withdrawal at cooling regions 9, 10 of walls 4, 5 equals the respective reference values. The computer 30 stores the said measured values as a function of the throughflow quantity of coolant and determines the attained maximum value of heat withdrawal per unit quantity of  coolant throughflow. This max value is then fed to the regulator to serve;as a new reference value. Alternatively measurement may be effected at the wide sides and control of heat withdrawal effected at the narrow sides. There may be more than two cooling regions or chambers per side in which case the regions of a controlled side may be controlled successively starting from the measuring side. The narrow sides converge toward the mould base.

Title: Improvements in the illumination and steering control of vehicles
IPC: B60Q1/124
Filed: 1923-09-03
Abstract: 224,934. Barker, W. Sept. 3, 1923. Adjusting reflectors from a distance.-In means for directing vehicle lamp reflectors either automatically with the steering-gear or by hand-operated mechanism, provision is made whereby small movements of the control mechanism from the normal position are not transmitted to the reflectors, further movement causing the reflectors to be turned quickly through the full range of movement provided, after which they remain stationary during any further movement of the control mechanism in the same direction. In the form shown in Figs. 1 and 2, which is suitable for operating reflectors one at a time according to which direction the vehicle is about to turn, a reflector a is mounted on a rotatable spindle b to which is secured a lever c normally held against a stop by a spring h or weight. The lever is provided with a cam surface which is engaged by the end e of the lever f when the latter is rotated about its pivot d by a rod g connected to the, control mechanism. The cam surface of the lever c is so shaped that, when displaced to the position shown dotted, it is concentric with the pivot d so that the later movements of the lever e do not cause further movement of the reflector. Fig. 3 shows a construction employed for turning the reflectors in both directions, each reflector being mounted on a spindle b carrying a cam n, the surfaces o of which become concentric with the pivot d after the cam has been displaced by the rocking of the lever f connected to the control mechanism, so that continued movement of the lever f does not cause further movement of the reflector. A modification is described in which a cam similar to the cam n is operated directly by the control mechanism, the reflectors being mounted on a spindle carrying a lever similar to the lever f. In a further modification, Fig. 7, the position of the reflector mounted on the spindle b is positively determined by a pin e on the pivoted lever f engaging a cam-shaped slot p in a member c secured to the spindle. The end portions q of the slot p are curved and disposed so that they became concentric with the pivot d when the member c is displaced by movement of the pin e, thus permitting the reflector to remain at rest during further movement of the pin e in the same direction. Specifications 11778/06. 5261/09 and 23677/14, [Class 118 (ii), Signals], are referred to.

Title: Vapour-phase catalytic olefin oxidation process
Inventor: FETTIS GORDON CHEYNE
IPC: B01J27/19
Filed: 1964-05-06
Abstract: Unsaturated aldehydes and/or unsaturated carboxylic acids especially acrolein and/or acrylic acid, are made by a process which comprises reacting an at least C3 alkene, especially propene, in the vapour phase, at an elevated temperature, preferably from 200 DEG  to 650 DEG  C., particularly between 300 DEG  and 500 DEG  C., in the presence of a catalyst containing Ni, Mo, Te, P and O, wherein there are per gm. atom of Mo, 0.1 to 1.0 P and 0.01 to 0.5 Te, and the Ni proportion is preferably 0.5 to 1.5.  The catalyst may be supported and the reactant gases may contain diluents, e.g. steam or nitrogen. The examples describe the oxidation of propene to acrylic acid and acrolein.ALSO:Catalysts containing nickel, molybdenum, tellurium, phosphorus, and oxygen especially containing 0.1 to 1.0 g atoms of phosphorus and 0.01 to 0.5 g atoms of tellurium per g atom of molybdenum, and particularly 0.5 to 1.5 g atoms of nickel per g atom of molybdenum and useful for the vapour phase oxidation of an alkene having at least 3 C atoms with molecular oxygen (see Division C2), and may be made by mixing aqueous solutions or suspensions of the Ni salt, H3PO4, or molybdate, TeO2 or a tellurate or telluric acid followed by evaporation and ignition.  Especially favoured starting compounds are the salts containing readily ignition removable ions e.g. nitrates and ammonium salts.  In the examples glass supported catalysts are prepared with the following atomic compositions Mo = 1, Ni = 1, Te = 0.1, P = 0.3, Mo = 1, Ni = 1, Te = 0.2, P = 0.3 by mixing an aqueous, free ammonia containing ammonium molybdate solution with a nickel nitrate and phosphoric acid containing solution and the recovered, washed precipitate is ball milled with TeO2 followed by drying and ignition.  The glass is added thereafter.

Title: Improvements in or relating to knitting machines
IPC: D04B9/18
Filed: 1933-07-04
Abstract: 422,059. Knitting. STANDARD-TRUMP BROS. MACHINE CO., Laconia, New Hampshire, U.S.A.-(Assignees of Shelmire, S. R.; Laconia, New Hampshire, U.S.A.) July 4, 1933, No. 18992. Convention date, July 18, 1932. [Class 74 (ii)] In circular machines for knitting stockings &c., having patterns in wrap yarns and with or without a double sole and gusset toe, the wrapping device is carried by a bracket 42 which may be moved upwardly to gain access to the needle-cylinder either with the latch ring or independently thereof. Sliding latch needles, divided into sets according to the length of their butts are operated by a single set of stationary cams 136, 138, 140, 142, 161, 163 &c. Cams 144, 146, 148 on one side of the feed point and cams 150, 152 on the other side provide for the formation of gusset toes. The cams 150, 152 also perform the functions of switch cams. Various of these cams are controlled by devices including a series of sleeves nested together. Below each needle there may be intermediate jacks 10 and lower rocking jacks 14, the removable butts of which are acted on by a stack of fingers 180 controlled by a trick wheel so as to cause the corresponding jacks to fail to take wrap yarns. The fingers may be selected direct from a drum 126, which overrides the trick wheel selection. The shoulders 18 of the jacks 14 are acted on by cams 164, 172 and 174. The drive for the wrap yarn assembly includes universal connections 56, 58. The wrap yarns proceed from bobbins 70 mounted on pegs 68 in a plate 66 and through tubes 72 surmounted by spring tensions. Tubes 78 conduct them to rocking wrap fingers 80, held in place in the tricks of cylinders 82, 83 by a spring band 88. The twisted lower ends of the fingers 80 pass round needles when operated on by cams 92, 94, 112. The cams 92, 94 are controlled by levers 102, 104, 108 and 110 mounted on a post 107. The lower ends of the levers 108, 110 are struck by arms 114, 116 mounted on nested shafts 118, controlled by cams on the drum 126. A steady pin 128 on the post 107 receives an extension carrying a spring latch and so holds the bracket 42 firmly in active position. The wrap yarns are prevented from fouling the double sole yarn cutting and clamping devices by placing the latter outside the needle circle. There is also provision for holding the double sole yarn away from the needle circle within the normal face of the latch ring and for maintaining it there by the use of tension and take-up devices. When the double sole yarn is held by the clamp a finger 336 draws the slack into a position above the needles where it will not be seized by them. This device also enters the double sole yarn in a slot 414 in the latch ring thereby preventing it from being fed to the needles at times when it is not required to be incorporated in the fabric. The knitting of a sock from rib top to toe is described in detail.
