Title: Improvements in driving mechanisms
IPC: G05G15/04
Filed: 1948-09-02
Abstract: 656,067. Control of motors; actuation of switches. IGRANIC ELECTRIC CO., Ltd. Sept. 2, 1948, No. 23165. Convention date, Sept. 5, 1947. [Classes 38(iii) and 38(v)] [Also in Group XXIV] A driving mechanism comprises a drive shaft, a coupling for connecting a driven device to the drive shaft and an intermittent gear operating connection between the coupling and the drive shaft to control the coupling to maintain the coupling in released position while the angular position of the drive shaft lies within a prescribed range and for engaging the coupling when the angular position lies outside that range, whereby the driven device is driven only when the drive shaft is rotated outside the range. The driving mechanism may form part of control apparatus for an electric motor-driven sluice gate which has a long range of travel between upper and lower limits and is accurately controlled within zones near such limits by means of a switch which may be of the travelling-nut type. The operating screw 5 of the limit switch LS is coupled to the gate through mechanism 6 which drives the screw during movement of the gate in the extreme zones and locks it during the remainder of the range. A shaft 7 is driven by a pinion 9, which meshes with a rack fixed to the gate, and is adapted to be coupled to a shaft 8 to drive the screw 5. A circular cam 11 operates the coupling which comprises flanges 13, 14 fixed to shafts 7, 8, respectively, pins 15, 17 being adapted alternatively to engage apertures in flange 13 or stops 19. The cam 11 comprises segments 26, 27, having bevelled faces 26a, 26b, and 27a, 27b cooperating with rollers 24 and 25 respectively so as to move element 20 to alternate positions and adjust the position of the flange 14 by means of rollers 22, 23. An intermittent gear drive between cam 11 and shaft 7 comprises three sets, each comprising a gear wheel, operating arm, and locking disc. Arm 30a is driven from shaft 7 through gears 39, 40, and when moved in either direction, steps gear wheel 29c through one-fifth of a revolution for twenty-five revolutions of the arm. The gear wheel 29c is fixed to cam 11, so that, when the gate moves upwardly from its lower zone, the segment 26 engages roller 24 to disengage the coupling and to maintain it disengaged until the gate is moved into one of the extreme zones, whereupon segment 27 moves the flange 14 into the engaged position for operation of the limit ,switch in these zones. The relative lengths of the two extreme zones of travel may be adjusted by means of the setting of the switch LS.

Title: Improvements in appliances for playing a board game
IPC: A63F3/00
Filed: 1925-09-22
Abstract: 247,110. Knowles, C. S. Sept. 22, 1925. Board games.-A set of game appliances comprises in combination a board indicating landing points for an army and navy, and bases for opposing forces, a number of members representing aeroplanes, battleships or the like adapted to be moved over the board, a plurality of tokens representing resources of the players for initiating and maintaining a contest between the players, and a card or like means for determining by chance the members of the forces to be marshalled by the opposing players. The board foldable about the lines 2, is in the form of a map of the world and is marked with equidistant circles 3 - - 6 on to which the " men " are moved. Bases 7, 8 for the opposing players are also marked on the board. The men consist of sixty blocks of the form shown in Fig. 2, divided into sets of fifteen each, the different sets bearing representations of aeroplanes, battleships, airships and submarines respectively, and being also distinguished from each other by the diverse colouring of a portion 22 of the surfaces of the blocks. Within each set the blocks are distinguished, and their fighting powers are indicated by designations 23 denoting military or naval rank, marked on one edge of each block. The sets also include blocks designated on the edge by the words " Buddy," " Dummy," " Fooler " and " Spy." For each block or man a card such as that shown in Fig. 6, is provided, thus forming a pack of sixty cards. The pack is used for determining by chance the blocks to be used by the players at the commencement and during the subsequent playing of the game. Forty-eight rectangular counters, Fig. 10, marked with various numerical values are used by the players for making payments during the game. Each player also has twenty-five distinctively-coloured indicators, Fig. 13, which are placed upon the men when in their initial positions but are removed as each man is moved. In playing the game each player places twelve men, (determined by turning up the cards, Fig. 6) upon the first row of circles adjacent his base and arranges his men so that the designations 23, Fig. 2, cannot be observed by his opponent. The players then play in turn and endeavour to capture opposing men, inflict penalties requiring payment, and to pass one of their men into the opposing base.

Title: Method of and device for measuring the angle between the plane of  polarization of plane polarized light and a reference plane
IPC: G01J4/04
Filed: 1971-04-19
Abstract: 1322470 Investigating polarized beams CARL ZEISS-STIFTUNG [trading as CARL ZEISS] 19 April 1971 [7 March 1970] 23721/71 Heading G4H [Also in Division G1] In a device for measuring the angle "α" between a plane polarized light beam 1 and a reference plane, the light beam 1 is passed via a rotating analyser 2 on to a photo-cell 4 and the resulting electrical signal is processed by a D.C. amplifier 4, a high gain differential amplifier 5 and fed into a digital circuit 7 which also receives a signal representing the reference plane. The reference signal is provided by a light source 11  and detector 10 arranged about an opaque rim 9 on the analyser 2 as shown. The differential amplifier 5 also receives a constant D.C. voltage by means of a variable resistance 6 and as a result has a square wave output in which each square wave pulse is centred about the angle of minimum passage of light through the analyser (Figs. 2a, 2b, not shown). The digital circuit, shown in Fig. 3, provides a digital value for the minimum angle. The circuit comprises two bi-stable flip-flops 16 and 17 which may be turned on "O" or off "L" by positive going signals only. The pulse U 12  representing the reference plane turns on the flip-flop 16 and allows pulses from a pulse generator to pass through an AND gate 18 and an OR gate 19 to a counter 8. Then the positive going signal provided by the side 14 of the pulse U 5  due to the polarized light beam switches off the flip-flop 16 and passes via an AND gate 20 to switch on the flip-flop 17 and the pulses from the pulse generator then have to pass via a 2 : 1 reducer stage before they pass via an AND gate 23 and an OR gate 19 to the counter 8. Finally the negative going side 15 of the pulse U 5  switches off the flip-flop 17 by way of a negative stage 24. Thus the value on the counter 8 is a measure of the position of the angle of the minimum passage of light and is thereby a measure of the angle of the plane of polarization. At the end of each rotation of the analyser 2 after read out of the counter 8, the counter is immediately cancelled through input 25. In an application to an interference microscope, Fig. 4, comprising a light source 30, a collector lens 31, a polarizer 32, a condenser lens 33, a beam splitter 34 a #/2 plate 35, a beam uniter 37, an objective lens 38, a #/4 plate and an eyepiece 41, the object under investigation is held at the object stage 36 with a comparison medium in the paths of the measuring and comparing polarized rays 43 and 42 respectively. The difference of the refractive values of the object under investigation and the comparison medium is then represented by the angle of rotation of the polarized light and it is measured by an arrangement similar to the Fig. 1 embodiment.

Abstract: 360,481. Lamp shades. HANSEN, J. E. M., 3, Oresundsvej, Copenhagen. Aug. 7, 1930, No. 23734. Convention date, Aug. 8, 1929. [Classes 75 (ii) and 75 (iv).] In a lamp shade in which certain rays of light pass through two members made of ground glass or other transparent diffusing material, the outer member is so shaped and arranged with respect to the inner member that rays which are reflected by the outer member are projected downwardly between the. two members without further penetrating either of them. In the form shown, a ray 16 from a filament is diffused by an inner member' 12 into a group of rays 17, some of which are diffused by an outer member 11 into groups of rays 18 and some of which are reflected downwardly by the member 11 as groups of rays 19. The members 11, 12 may be made in one piece or they may be made separately and have varying transparency and diffusing properties. They may be mounted on the lower edge of the reflector 8 of a suspended lamp, or they may carry the reflector of a pedestal lamp. The surface of the member 12 between the lines B, D may be waved or grooved, or it may be fitted with one or two more additional members similar to the member 11 so as to increase the range of double diffusion.

Title: Improvements in or relating to variable-speed power transmission gearing
IPC: F16H29/22
Filed: 1930-08-07
Abstract: 360,483. Driving-arrangements for bobbin-winding machines. TAYLOR, H. G., 230, Friern Road, East Dulwich, London. Aug. 7, 1930, Nos. 23736/30 and 15291/31. [Class 120 (ii).] Continuously-variable gearing for varying the speed of a shaft 46 driven from a shaft 13, and adapted for driving a bobbin at a decreasing speed in accordance with the increase in diameter as it is wound, comprises a plurality of members 16 each reciprocated by a driving-cam 14 and serving to oscillate a transmission lever 24, the fulcrum 28 of which is moved automatically so as to vary the speed at which a wheel 42 is driven through ratchets 44, a rack 40, and a link 37, the cams 14 being driven by a chain from the driving-shaft 13 of an epicyclic train 49, 52, 50 and the wheels 42 connected so as to drive the carrier 51 of the planet gears 52. The linkwork gearing drives the carrier 51 at a speed which slowly rises from zero, so that the speed of the train-driven shaft 46 slowly falls from a maximum. The levers 24 pass freely through blocks 27 which oscillate on the trunnions 28 supported in a fulcrum frame 30. The levers 24 are kept in position by the linearly-sliding links 37. The members 16 slide in guides 20 and are connected by links 22 to the levers 24. The oneway driving rollers 44 are supported on hard plates 47. The speed transmitted by the linkwork ratchet mechanism is varied by raising the fulcrum frame 30 sliding in guides 33 from a no-drive position in which the fulcra 28 are in line with link pivots 36. This automatic raising of the frame 30 may be effected through a suitably driven snail cam or screw. In the arrangement shown, a rack 35 fast on the frame 30 is raised and allowed to fall automatically by a pinion 62, Fig. 4, intermittently driven from an engine-driven shaft 53. Pinion 62 is fast on a sleeve 61 loose on a spindle 59 driven constantly at a speed suitable to the size of the bobbin through change gears 56. A ratchet wheel 60 on spindle 59 thus rotates constantly, and an arm 63 carried on the sleeve 61 is connected to it intermittently by a pawl 64, Fig. 3, pivoted on the arm. Pawl 64 is held either in or out of engagement with the wheel 60 by a cam plunger 65 also carried by the arm 63. With the pawl engaged, arm 63 is moved up and to the right of Fig. 3 until a projection 66 engages a trip cam 68 whereby the pawl is turned to disengaged position. The frame 30 descends by its weight until the pawl 64 strikes a fixed trip 72 and is thrust back into engagement to be raised again. The duration of the automatic speed change is adjusted by adjusting the position of the trip cam 68 by a hand-wheel 69, Fig. 4, with a pointer 70 moving over a dial 71.
