Title: Improvements in or in connection with globes, shades, and like lighting fittings
IPC: F21V5/00
Filed: 1926-06-18
Abstract: 269,360. Biheller, S. June 18, 1926. Globes and shades.-A lamp globe or shade comprises a body portion and a base portion consisting mainly of a series of hollow radial downwardly directed ridges, the curvature of the body portion c being such that some or all of the rays reflected therefrom strike the inner surfaces of the curved walls d of the radial ridges, are reflected through the vertical walls e on to the outer surfaces of the curved walls of adjacent ridges, and are then reflected downwardly and outwardly in all directions. The vertical walls e are transparent whilst the remainder of the globe is opaled or otherwise rendered sufficiently opaque to prevent a direct view of the gas, electric, or other source of light, but not so much as to prevent a soft diffused light passing through it.

Title: Improvements in or relating to retractable undercarriages for aircraft
IPC: B64C25/20
Filed: 1941-12-01
Abstract: 556,550. Stays for hinged articles. AUTOMOTIVE PRODUCTS CO., Ltd., and WATERS, C. D. Dec. 1. 1941, No. 15476. [Class 65 (i)] [Also in Group XXXIII] A folding strut which may be the main or a bracing strut for an aircraft undercarriage, is looked in its extended position by a toggle linkage extending across the pivot and folding in a plane parallel to the plane in which the strut folds, at least one end of the toggle linkage being attached to the strut at a point offset from the thrust line of the strut in a direction parallel to the planes of folding, and the toggle becoming fully extended as the strut is extended. Means are provided for resisting movement of the toggle when it is extended. A wheel fork 12 pivoted to the aircraft at 13 is braced in its extended position by two folding struts each comprising two parts 17, 18 pivoted together at 19, the two pivots being connected by a transverse shaft so as to move in unison. Each strut is looked in its extended position by a pair of toggle links 23. 24 pivoted to offset lugs 22 on the strut parts 17, 18. The link 24 is forked at both ends but. the link 23 is Bat and has an extension 26 which bears against a pin 27, extending across the forked end of the link 24, when the links are in line. A lever 28, pivoted on the same pivot as the link 24, has a slot 2,9, co-operating with a pin 30 extending across the upper forked end of the link 24, and the end of the lever is pivoted to a forked member 32, the other leg of the fork being connected to a similar lever on the other strut. The forked member 32 is connected by a link 34 to a bell-crank-lever 35, movable by a jack 37. In the form shown the end of the extension 26 is engaged by a latch 41 connected by a spring telescopic link 42 to the lever 28. Initial movement of. the jack 37 causes the lever 28 to withdraw the latch 41, after which the end of the slot 29 engages the pin 30 and breaks the joint of the toggle links and starts the folding movement. Continued movement causes a slotted link 31 to engage the shaft connecting the pivots 19 to continue the folding of the struts 17, 18 until they are engaged by an updatch 50. During extension of the undercarriage the initial movement of the jack causes a projection 51 in the link 31 to release the latch 50, and the undercarriage falls, the pressure of the lever 28 upon the links 24 finally causing complete extension of both the toggle and strut and the re-engagement of the extension 26, with the latch 41. In a modified form the latch 41 is omitted and the extension 26 is kept pressed against the pin 27, when the toggle is extended, by a spring arranged about the lower pivot of the link 23.

Title: Improvements in jacking mechanism for mobile marine platforms
IPC: E02B17/08
Filed: 1959-05-06
Abstract: 846,851. Drilling-barges. DE LONG CORPORATION. May 6, 1959 [May 8,1958], No. 15611/59. Class 68(2). A mobile marine drilling or like platform is maintained positively in its raised position by the engagement of pins on the jacking means with holes in the supporting legs. The pins may be locked in the holes and the jacks removed. As described, the legs 20 each have at least two longitudinal jacking bars 22 arranged circumferentially around the leg, each bar 22 being provided with vertically spaced holes 25 to receive pins 182, 226 when projected by presses 196, 228, and with two jacking sections, one section comprising a columnar structure 26 secured, with cushioning 78, 62, to the deck 12 and mounting the pin 226 and its press 228, and the other comprising a box-like structure 106 slidable on the column 26 and carrying the pin 182 and its press 196. The column 26 is slotted at 90 to permit the pin 182 to move vertically with the slide structure 106. The bar 22 is embraced by claws 54, 230 on the stationary column and by claws 220 on the sliding structure 106, which is moved up or down by two pairs of single acting cylinders and pistons 126, 154, the means 154 bearing against a cross-head structure 104 including a heavy plate 100. When the platform is fully raised, the weight is taken by the pin 182 projecting into a hole 25, through the jacks 154, head 104, column 26 and connections with the deck 12. The load is then put partly on to the pin 226 by inserting shims 234 between the plate 100 and a heavy plate 120 at the top of the column 26, the shims being angle-shaped to pass partly around the corners of the column 26 and notched to receive a sliding locking bar which prevents them from shifting. The pin 226 is projected into a hole 25 and, if desired, the jacks 154 may be removed. The pin 182 has spaced bars 186 and a slotted plate 188 welded thereto to form a recess for the head 190 of the piston of the operating press 196. This connection permits the press to be disconnected from the pin 182 and removed, the pin 182 being prevented from retracting by wedges 218 engaged in slots in the structure. Similarly the press 228 may be removed from the pin 226 which also is locked by wedges.

Title: Alignment control of liquid crystal molecules
IPC: G02F1/1337
Filed: 1978-04-20
Abstract: In order to influence the orientation of liquid-crystal molecules in a liquid-crystal display when no voltage is applied to the electrodes, an orientation layer is vapour-deposited onto the substrates which bound liquid-crystal cells. In order to achieve the orientation at a desired angle relative to the substrate surfaces, a plurality of vapour depositions are undertaken simultaneously and successively from two or more angles relative to the substrate. A device for undertaking such vapour depositions has a rotation element (72) on whose circumference substrates (74) are mounted. The rotation element (72) moves the substrates (74) past a vapour source (84). The vapour jet produced by this vapour source is split up by an impact plate (76) into two parts which successively impinge onto the substrates alternately at different angles when the element (72) rotates. <IMAGE>
Patent GB-156589-A (GB)
Abstract: 156,589. Valkenburgh, J. F. Jan. 9, 1920, [Convention date]. Dividing - instruments. - An instrument for dividing and multiplying angles comprises a frame 1 to which is pivoted at 3 an arm 4 capable of moving around the semicircular edge of the frame. A cord 8 attached to the arm is passed around the semicircular groove 9 and is attached at its outer end to a block 6 which can move along a groove 5 and carries a pointer 7. To divide an angle acb into say six parts a circle is drawn with centre c and a pin on the pivot 3 is inserted on the circumference of the circle. The arm 4 is moved until its edge 4a lies over the point a and the cord stretched taut. The arm is then turned until the edge 4a lies over the point b. The distance fg through which the pointer 7 has moved is then divided into the required number of parts and the arm brought to positions corresponding to each subdivision. The radii such as ch then give the required division of the angle. In a modification, the cord is dispensed with and the arm 4 carries a pinion gearing with a rack which carries the pointer 7.

Abstract: 980,704. Automatic exchange systems; non- contact-making relays. WESTERN ELECTRIC CO. Inc. May 1, 1961 [May 4, 1960], No. 15676/61. Headings H3B and H4K. The presence of current or no current in a circuit, and particularly a telephone subscriber's line circuit, is detected by causing the current to magnetize a bar of magnetic material 23 so as to saturate the central portion and decouple an interrogating winding 30 from a read out winding 31 in an aperture 24. In the absence of current, which would be drawn from the exchange battery over the subscriber's loop including windings 28 and 29, the windings 30, 31 couple by virtue of the closed loop of material about the aperture 24, the bar 23 having no remanence of any significance because of the demagnetization inherent in its shape. The aperture 24 may be displaced across the width of the bar to provide unequal limbs on either side, the limb of smaller cross-section determining the rate at which the windings 30, 31 are decoupled with increasing current in windings 28, 29. The plate may have two apertures such as 54a, 54b, shown in Fig. 5, the windings 30, 31, passing through one aperture and returning by way of the other.

Title: Power-actuated type bar drive for typewriters, printing calculating machines, or the like
IPC: B41J23/06
Filed: 1957-05-17
Abstract: 853,122. Typewriters &c. JULICH, W. May 17, 1957, No. 15762/57. Class 100(4) A power-operated type bar action has two pawls for successive engagement with successive teeth of a toothed power shaft to positively actuate and then return the type bar. Depression of a key 2 rocks a pawl 7, Fig. 1, clockwise into the path of a tooth 13 of a power shaft 1 so that actuation of the type lever 22 is caused through a linkage 7, 10, 19-21. Movement of the pawl 7 releases a return pawl 14 which is urged by a spring 16 into the path of a second tooth 25 which after movement by the tooth 13 is complete engages the pawl 14 to positively return the type lever 22 through a linkage 14, 10, 19-21. A spring 11 returns the pawl 7 and re-latches it with the pawl 14. In a modified construction, Fig. 4, depression of the key 2 through a lever 28 withdraws a pawl 31 from a second pawl 35 allowing a spring 36 to rack the latter so that it comes into the path of a tooth 26a on a driving shaft 26. The pawl 35 is mounted on a lever 34 which is thus driven anti-clockwise causing the type bar 44 to strike and placing an arm 46 in the path of the next tooth 47 which restores the lever 34 and the type bar. As the lever 34 is restored a pin 45 brushes along the upper edge 35b of the pawl 35 restoring it against the spring 36 so that it becomes re-latched by the pawl 31 out of the path of the toothed shaft 26.

Title: Improvements in compensated asynchronous electric motors
IPC: H02K17/38
Filed: 1928-05-31
Abstract: 293,021. Forges et Ateliers de Constructions Electriqus de Jeumont. July 1, 1927, [Convention date]. Alternating - curr e n t induction machines. - For phase compensation in an asynchronous motor, the machine is cascaded with a separately driven exciter of a non-selfexciting series generator type having its brushes set behind the neutral axis by an angle of less than 180 electrical degrees and driven by an auxiliary motor of such a type that its speed falls considerably with increasing load. In the form shown, the main motor A is cascaded through its slip-rings with the series wound commutator exciter E, which is driven by an asynchronous motor M having a rotor resistance R. The exciter brushes, as shown in Fig. 2, have a negative lead. The exciter is thereby given a resistant torque which is a function of and increases with the load of the main motor. The speed of the auxiliary motor and exciter accordingly varies inversely as the load on the main motor and the compensation is maintained constant within wide limits of the load variation.

Title: Compressed air operated time-dependent dead mans handle with  vigilance monitor for rail vehicles
IPC: B60T17/20
Filed: 1971-05-20
Abstract: 1324956 Vehicle dead man's handle RHEINSTAHL AG 20 May 1971 [11 Aug 1970] 16035/71 Heading B7H [Also in Division F1] A dead-man's handle arrangement for a rail vehicle comprises compressed air operated fluidic elements wherein, upon inattentiveness of the driver, an audible signal is operated ignorance of which results, after a predetermined interval, in automatic braking. Pneumatic switch 2, which has to be closed at regular intervals to confirm vigilance, causes, in the ON position, air from 1 to be switched from output 58 to 5 of OR/NOR gate 4 whence it flows to control input 8 of flip-flop 9 to switch air from output 10 to 11. Thus pressure in fluid resistor 14 rises as that in 15 decays and a short pressure pulse occurs at the control input of AND gate 13 whose output 18 is fed to control input 19 of a binary counting cascade 64 which counts pulses produced by an astable multivibrator 63. As shown, a delay of 16 pulses of the multivibrator 63 elapses between a signal arising at output 18 of gate 13 and a signal arising at output 21 of counter 26 which switches the output of AND gate 60 to 62. This causes a signal to arise at control input 42 of OR/NOR gate 40 switching its output from 43 to 44. The disappearance of air pressure from 43 causes the output of OR/NOR element 45 to be switched from 48 to 49 thus sounding the horn 50. If the driver does not operate switch 2 again, after a further eight pulses from multivibrator 63, the output of counter 25 switches 22 to 21 producing a control input at 54 of AND gate 51 which, with the already existing control input at 54 produces a switching from output 52 to 53 which output is amplified at 57 to operate the air brakes of the vehicle.
