Abstract: 165,223. Denson, J. D. March 24, 1920. Stopping way; planes, construction of; steering, balancing, and regulating altitude.-An aeroplane is fitted at its tail with a collapsable chamber, the mouth of which can be opened to admit air to retard a forward or diving movement; and the fincarrying board forming the top of the chamber can be elevated about its forward end without opening the chamber, to prevent nose diving. The board 42 carries a fin 48, and is connected to the sides and rear of the tail 11 of the machine bv fabric 43 which forms the sides of the collapsable chamber. The mouth of the chamber can be opened by raising the front portion of the board 42 by a hand-lever 44 which is connected to the board by links and levers 46, 45, 40, 40<1>. The rear end of the board can be raised to varying extents by sliding the fulcrum blocks 32<11> along its under surface. These blocks are carried by a sliding rod 32, pivoted to a rod 31 which is connected to the upper crank 29 on a shaft 28. By pressing upon one or other of the pedals 38, which are connected respectively to the upper and lower cranks 29, the fulcrum blocks 32<11> can be moved backwards or forwards. A hand-lever 27 is linked to a transverse shaft 23 carrying cranks at its ends for raising or lowering the rear ends of narrow longitudinallyextending planes pivoted near their front ends to the sides of the fuselage.

Title: Improvements in or relating to straight bar knitting machines
Inventor: WICKARDT KURT WILLI
IPC: D04B11/00
Filed: 1950-04-12
Abstract: 715,676. Knitting-machines..THIEDE, W. O. April 9, 1951 [April 12, 1950], No. 8955/50. Class 74 (2) In a straight-bar machine a device such as a lead screw for adjusting thread carrier travel is intermittently actuated through a consantly rotating driving member having at least one ,projection slidable thereon between a position in which it will engage one of a plurality of slots spaced equidistantly around and extending inwardly from the periphery of a rotatable driven member and a position in which it will avoid the driven member. Shaft 8, Fig. 1, is intermittently rotated by a constantly rotating shaft 1, by the engagement, under pattern control, of pins 4 or 5, carried on a drum 2 on shaft 1, with slots 23 or 24 of a Maltese Cross 9 on shaft 8. The pins are mounted in pairs 4, 5 on slides 3 carried around part of the circumference of the drum 2 and movable longitudinally thereof, one way or the other, by cam plate 11 or 12 lowered into the path of pins 4 or 5. Plate 11 or 12, when operative, causes the associated pins 4 or 5 to follow such a path that each of the other pins 5 or 4, in turn, engages a slot 23 or 24 to turn shaft 8 through 90 degrees in one direction or the other. A fixed cam plate 20 returns the pins to their former path. Between successive rotations, the shaft 8 is located by coaction of the nose of a spring-urged' lever with notches in a disc 10 on shaft 8. The pairs of pins may be of two or more differing lengths, and the cam plates movable from the inoperative position into different operative positions, in which they engage some or all of the pins. In a modification, Figs. 8 and 9, driving pins 84 are carried by slides 83 movable radially of a constantly rotating disc 82 by means of a groove 91b in a gate 91 swingable from the position of Fig. 8, in which the pins are caused to follow a circular path 101 into a position in which the groove diverts the pins into a V-shaped track 88, 89 which causes them to enter the slot 98 of a Maltese cross 97 and so rotate' shaft 96, a quarter-revolution at a time. The gate 91 is swung to the shaft driving position for differing periods by cams 103 or 104 into the path of one or other of which a cam follower 94 is brought by one or other of lugs 113, 114 of differing height on a chain 112. The direction of rotation of a shaft 119, driven by shaft 96, is determined by a cam drum 124 which, through a spring- returned bell-crank 120, shifts a clutch 118, slidably keyed to shaft 119, from one to the other of bevel gears 116, 117, rotatable on shaft 119 and driven by a bevel wheel 115 on shaft 96. The device may be used to rack a lead screw controlling the stroke of thread carrier rods Fig. 7 (not shown) or controlling splicing stops or narrowing points, or for racking control shafts or control drums.

Title: Timepiece
IPC: G04B1/22
Filed: 1932-03-29
Abstract: 397,235. Watches &c. VUILLEUMIER, M., Le Sentier, Vaud, Switzerland. March 29, 1932, No. 8992. Convention date, April 1, 1931. [Class 139.] In a time-piece wherein an auxiliary spring drives the movement during winding of the main spring 8, the latter is lodged in a recess 9 in the casing 1, is fixed to the casing at its outer end, and, at its inner end, is connected to a collar 7 rigid with a hollow shaft 6 journalled in the casing at 6<1> and in the back piece 2. The first wheel 19 of the movement 3 is driven through shaft 6, wheel 10, pinion 11, ratchet wheel 12 (rigid with 11), a pawl 20 (mounted on wheel 22), wheel 22 and auxiliary spring 21. Wheel 22 which is connected to the inner end of spring 21 has ratchet teeth opposed to those of wheel 12, and coacts with a pawl 23 mounted on the frame. Normally, pawl 23 is inoperative, but during winding of the mainspring by member 13, pawl 20 becomes inoperative and wheel 22 is locked by pawl 23, spring 21 driving the movement. The gear ratio 10, 11 is such that the mainspring winds the auxiliary spring to the same fraction of its maximum tension. Hand setting is effected by rotation of a knob 15 the shaft 14 of which carries the minute hand sleeve. The main spring may alternatively be wound by a radial winding stem carrying a pinion adapted to mesh with a crown gear carried by the ratchet wheel 12. In this case hand setting would be effected by the usual sliding pinion. The casing 1 may be screwed, as at 17, to a support 4.

Filed: 1954-03-29
Abstract: 753,887. Electromagnetic relays. TRIGGS, W. W. (Hart Manufacturing Co.). March 29, 1954, No. 9075/54. Class 38(5) A small relay comprises a hollow core 20 threaded on to an upstanding tubular boss 11 of the base 10, the core carrying a winding 21 and a threaded bush 25 guiding a plunger 27 biased downwardly by a spring 38. The boss 11 is bifurcated by a slot 13 and a disc 30, notched at 31 to receive the bifurcations, is soldered to a plunger flange 28 whereby upward movement of the plunger 27 when the winding 21 is energized is limited by the engagement between the disc and the lower edge of an enclosing shell 22, Figs. 2, 3. A recessed insulating block 40 on the base 10 carries four fixed contacts 42, an insulating cover plate 45 carrying four fixed contacts 44 similar, and opposite, to the contacts 42. The contacts 42, 44 have terminal posts 43, 46, respectively, the posts 46 carrying compression springs 62 and serving as guides for a pair of triangular insulating plates 60 joined by a sleeve 64 which embraces plate-extensions 63. Movable contact arms 50 having bifurcated contact ends 50 which co-operate, respectively, with the upper and lower contact of each pair 42, 44, receive the edges of the plates 60 and are positioned thereby, the other ends of the arms being freely mounted on terminal posts 52 and biased against part-spherical seatings 54 on the posts by springs 55. Each plate 60 has a pin 65 engaged by a common yoke 70 freely received on an extension 29 of the plunger 27 and having an arcuate surface 71 for engagement by the disc 30 when the winding 21 is de-energized whereupon the spring 38 overcomes the springs 55, 62 and the contacts 50 disengage contacts 44 and engage contacts 42. Good contact is ensured at each contact pair since the yoke 70 may tilt about the surface 71 and the plates 60 may tilt at right angles to the yoke on the posts 46.

Abstract: 905,921. Gear-cutters. GLEASON WORKS. March 16, 1960 [March 26, 1959], No. 9284/60. Class 83 (3). A blade for a face-milling cutter comprises a shank 23 for seating in a slot in a head and having a hole for receiving a securing screw 28, the shank having seating surfaces comprising opposite parallel side faces and a bottom face perpendicular thereto and, for seating the head of the screw, a top face 32 perpendicular to the side faces and at an acute angle to the bottom face, and the blade having an abutment 26, Fig. 8, for seating on the front face of the head. The bottom of each slot in the head is inclined and is contacted by a wedge 18 on which is placed a shim 21. Each wedge is adjusted by a screw 33. The top face 32 is inclined at 10 degrees and tightening of the screw causes the blade to move downwardly to bring the abutment 26 against the head. Any rotational movement of the blade, due to rotation of the screw, forces the abutment more firmly against the head. The screws have buttress threads. The blades may be inside-cutting or outsidecutting. For a left-hand blade 25a, Fig. 9, the abutment 26a is still provided in a position where it is forced against the head by rotation of the screw, and is thus at the trailing, instead of the leading, end of blade. The abutment may be provided at the leading end of the blade, however, if the screw is left-handed. Reference has been directed by the Comptroller to Specification 839,812.

Abstract: 1,037,414. Electric transformers. BRUSH ELECTRICAL ENGINEERING CO. Ltd. March 8, 1963 [March 10, 1962], No. 9327/62. Heading H1T. In on-load transformer tap-changing equipment in which a static switching element is used for the diverter switch arrangement associated with each tap, each static switching element is in the form of at least one pair of silicon controlled rectifiers connected in reverse parallel so as to carry both directions of current. The S.C.R.'s can be used instead of mechanical diverter arrangements, known mechanical switches still being used for selecting taps (Fig. 2, not shown) or the static switching elements, one for each tap, may be controlled to have selecting and diverting functions, no mechanical selectors being used in this case. The arrangement of reverse-parallel pairs A, B and C, D &c. (Fig. 3), one pair for each tapping, eliminates the need for selecting taps in any particular order, as occurs when mechanical selector switches are used. Another arrangement, having various stages R1 . . . R4 (Fig. 4, not shown) employs seven pairs of rectifiers in the line to each tapping, in the most economical arrangement, but needs a complex control system for gating the rectifiers. Instead of single reverse-parallel pairs of rectifiers, several such pairs in series parallel or reverse parallel strings can be used (Figs. 5, 6, not shown).

Title: Improvements in or relating to a telephone signalling system employing low frequencyalternating current
IPC: H04L25/04
Filed: 1955-03-31
Abstract: 769,369. Automatic exchange systems. GUEN, F. LE. March 31, 1955 [March 31, 1954], No. 9452/55. Class 40 (4). In a system in which D.C. pulses are converted into low-frequency, A.C. pulses for forward transmission, reduction in effective pulse duration which occurs when the initial instantaneous value of the A.C. pulse is below the operating level of a receiving relay is overcome by discharging a condenser into the line immediately prior to transmission of the pulse. As shown in Fig. 1, a relay 2 responds to D.C. pulses and connects a condenser 7 previously charged from a D.C. source 8 to a transformer 10 associated with a transmission line 11. Subsequently, when a slow-operating and releasing pulsetiming relay 3 pulls up, a 50 c/s. alternating source 9 is substituted for the condenser which is recharged when relay 2 releases at the end of the D.C. pulse. At the receiving end of the line, Fig. 2, the A.C. pulses are rectified and operate a relay 14 which controls a D.C. impulsing relay 16. When the latter relay responds, a swamping resistor 15 is connected in circuit with the rectifier to neutralize the non-linear characteristic which would otherwise affect the release time of relay 14. A more detailed circuit is also described, Fig. 3 (not shown), which includes the features of high-pass filters in the local speech circuits for blocking the A.C. pulses and discharge paths for the line over shunt resistors.

Patent GB-906729-A (GB)
Title: Azo triazole dyestuffs
Filed: 1960-03-18
Abstract: The invention comprises dyes of formula <FORM:0906729/IV (b)/1> where A is a benzenic or naphthalenic residue, B is a benzenic or naphthalenic residue in which the azo and triazole groups are in p-position, D is a benzenic or naphthalenic residue with the triazole ring N atoms in o-position, R5 is H, AlK or OAlK, m is 0 or 1, n is 1 or 2, p is 1 or 2, r is 0, 1 or 2 and R is NH-R1-OSO3X where X is H or an alkali metal cation and R1 is a straight or branched-chain member with 2 or 3 C atoms between N and O.  When A and D are derived from compounds of the aniline series the benzene nuclei may possess a condensed-on heterocyclic ring.  The dyes are made by conventional methods by forming appropriate triazolised dyes containing SO3H, SO2Cl or SO2NHR1OH groups and converting these groups to the SO2R group in a final stage.  Representative of A components are aniline -3- and -4-sulphonic acids, 2-amino- 5-nitrobenzene- 1-sulphonic acid, 1-naphthylamine-4-sulphonic acid, 6-nitro-2-naphthylamine-4,8-disulphonic acid and 6-(naphthol[11,21,4,5]-triazolyl)- 2-naphthylamine-4,8, 51-trisulphonic acid.  The residue A may contain substituents such as nitro, acylamino, alkyl, alkoxy, carboxy, azo and triazole groups. According to the groups present various other conversions such as acylation, urea and triazole formation, diazotisation, coupling, sulphonation and reduction may be carried out at different stages in the processes of production. Representative of compounds specified for B are 2-methoxy-and-methyl-aniline, 2,5-dimethoxy-aniline, N-ethylaniline and 1-naphthylamine-7-sulphonic acid. Illustrative of specified compounds D are 2-naphthylamine and its 6-mono- and 3,6-disulphonic acids, 3-methoxy-4-methyl-aniline and 2-(p-sulpho- and -chloro-phenyl)-5-aminobenztriazole.  Dyes, very fast to chlorine, are obtained when the products are free from amino and hydroxyl groups.  The dyes are used to colour hydroxy-group containing textile materials, especially natural and regenerated cellulose.  The dyeings may be made very fast by treating with acid-binding agents, preferably at elevated temperatures. Amide-containing textiles such as wool and silk may also be coloured. Examples are provided of the preparation of the dyes, mono- and poly-azo dyes being obtained, and their use in colouring cotton in orange shades.  Amongst various components used corresponding to A are dehydrothiotoluidinedisulphonic acid, 41-aminostilbene-2,21-disulphonic acid -4,111-azo-411-methoxybenzene and 41-amino-4-nitrostilbene-2,21-disulphonic acid. R1 is illustrated as ethylene and isopropylene.  Some of the above indicated final and intermediate conversions are also exemplified, e.g. polyazo dyes are obtained by urea formation and by glucose reduction of nitro groups. Specifications 837,750 and 904,800 are referred to.
