Filed: 1929-04-11
Abstract: 328,109. Vale, H. E. T. April 11, 1929. Board games.-A board, Fig. 1, represents an expanse of sea and is divided into spaces, certain of which have marks, such as arrows, representing the direction of the wind. Representations of sandbanks A, reefs B, icebergs C, " calms " D, land T, a harbour G, and a port P may also be provided on the board. The playing pieces are in the form of sailing ships Q, some of which may represent treasure ships and others privateers. The pieces have removable beads 13, 14, which represent sailing power, gun power, steering power, &c. The pieces are moved over the spaces in accordance with results obtained from the throwing of dice or from other chance apparatus. The treasure ships and privateers are assumed to " engage," and if the imagined " shots are successful, certain beads are removed from the piece that is " hit." Counters placed on four squares a - - d, at the centre of the board, according to results obtained from the throw of dice indicate the state of the tide. The board may also be marked with indications of the direction of currents. In a modification, the board is marked to represent a boat-race course, a game simulating yacht racing being played thereon.

Title: Improvements in multiple rope variable speed pulley transmission gear
IPC: F16H9/04
Filed: 1940-07-05
Abstract: 542,416. Variable-speed gearing. MASON, F. R. EMBLETON, R., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. July 5, 1940, No. 11311. [Class 80 (ii)] In a multiple rope or belt variable-speed gear an expanding pulley comprises coned discs 13 splined to a shaft 1 which is driven by gears 3, 4 from a power shaft 5. Alternate discs 13 are secured to rods 16 fixed to a sleeve 21 slidable on the shaft 1 and the intermediate discs 13 are fixed to rods 17 secured to a sleeve 22 slidable on the sleeve 21. The sleeves 21, 22 are carried by thrust bearings 26, 26a in housings 28, 28a screwed to a bracket 33. The latter and a bracket 12 at the other end of the pulley are connected together by a frame 45 and the whole can pivot about the axis of the driving shaft 5. Housings 28, 28a have gear wheels 31, 31a engaging pinion 36 on a spindle having a gear wheel 37. The latter can be rotated by a motor on a shaft 43 by a worm 42, wheel 41 and pinion 38. Rotation of the wheel 37 causes the housings 28, 28a to move in opposite directions and vary the pitch circle diameter of the expanding pulley. Slight turning of the brackets 12, 33, due to the driving torque adjusts the slackness of the belts. Relative movement of the housings 28, 28a may be obtained by cam means instead of the arrangement shown. In a modification, the adjustable pulley is mounted in a fixed pedestal 46, Fig. 6, and gears with a non- adjustable pulley 8 carried in a rocking frame 12a journalled on the driven shaft 5, the pulley 8 having pinions 3a engaging gear wheels 4a on the shaft 5. By this means the slackness is accommodated.

Title: Method of producing steel
IPC: C21C5/04
Filed: 1947-04-28
Abstract: In a method for the production of steel in open hearth furnaces there is added to the bath of metal and basic slag when the carbon has been reduced to a predetermined value and the slag has a low iron oxide content (i.e. 20 per cent or less by weight) an exothermic reaction mixture capable on ignition of reacting with the iron oxide of the slag and preventing the flow of iron oxide from the slag to the metal.  The exothermic reaction mixture may contain an oxidising material, e.g. sodium nitrate or sodium chlorate, and a non carbonaceous reducing material, e.g. ferro silicon or aluminium and the amount of reducing material should be sufficient to react with all of the oxidising material and the iron oxide in the slag but not enough to enter the molten steel.

Title: Function generator
IPC: G06G7/24
Filed: 1962-03-27
Abstract: 932,835. Logarithmic function generators. EASTMAN KODAK CO. March 27, 1962 [March 27, 1961], No. 11694/62. Class 37. A function generator (Fig. 1) comprises a phase reversing D.C. amplifier 10, a resistor 14 having one end connected to the input of the amplifier and its other end adapted to be connected to a source of operating voltage, a capacitor 11 connected in shunt with the amplifier, a tapped resistive chain 30 in series with a first feedback diode 31 also connected in shunt with the amplifier and a second feedback diode 33 connected between the tap on the resistive chain and a source of a first predetermined reference potential. The arrangement of the feedback diodes and reference potential is such that upon connection of the operating voltage, the output voltage will change from its initial value at first linearly with respect to time, then non-linearly and finally, linearly, but at a different rate than during the first period of linear change. The function generator is used to provide a voltage output which varies logarithmically with time, the specified equation being V = -25 log t, where V is the time after switching on the generator. Under non-operating conditions a positive voltage is applied to amplifier 10 from terminal 71 so that the voltage at the output of the amplifier is permanently negative, clamped to say -10V by Zener diode 24 and diode 22. By operating switch 70, a negative input is applied to the amplifier from terminal 72, and this is held at a fixed level by diode 18. This causes the output from the integrating amplifier to increase linearly (Section 611, Fig. 2) until it reaches zero volts, when diode 31 conducts so that the resistive path 30 is also brought into shunt with the amplifier and the continued output voltage rise is no longer linear (section 63<SP>1</SP>). When the voltage at tapping point 32 is such that diode 33 conducts, feedback through the resistive path ceases and the output voltage rise becomes linear again, but at a lower rate than at first (Section 65<SP>1</SP>). By suitable choice of parameters the variation can be made approximately logarithmic. The output from the integrating amplifier stage at 13 is applied to a further amplifier 41 which has a resistive input network 40. The output from this amplifier at 43 follows the output from amplifier 10 to point 66 (Fig. 3), corresponding to 66<SP>1</SP> (Fig. 2), at which point diode 51 in the input network starts to conduct, thus reducing the overall gain of the amplifier, so that the output voltage decreases more slowly (Section 67). As the diodes 52, 53 also start to conduct so further changes in the rate of decrease are brought about. The overall system can be arranged to closely generate a logarithmic output over time changes of 100 : 1, and the voltage output may be used for example in the accurate control of exposure times in photographic colour printing.
