Abstract: 995,127. Vehicles guided and supported by gaseous cushions. HOVERCRAFT DEVELOPMENT Ltd. Nov. 8, 1961 [Aug. 9, 1960], No. 27618/60. Headings B7K and B7L. A vehicle is maintained in spaced relationship to a prepared track by gaseous cushions. In Fig. 1, gaseous curtains from ports 3, 5, 9 create and contain air cushions to support and guide vehicle 2 relative to track 1. Various forms of track and vehicle are given in Figs. 2, 3, 4 and 7, not shown, whilst in Figs. 5 and 6, not shown, the vehicle is suspended from a divided, overhead track. Flexible curtains may be used adjacent the supply ports, Fig. 16, not shown. The cushions extend over the major portion of the vehicle's length and are contained at the front and rear by gaseous curtains. For highspeed vehicles, Fig. 8, a subdivided cushion 50 is contained by a continuous gaseous curtain and a small cushion 52 at the front of vehicle is at a pressure higher than the maximum stagnation pressure that could occur on movement of the vehicle. The vehicle is guided on vertical walls by cushions on small pads 56 which may be deflectable, Fig. 14, not shown, to avoid contact with the track on curves. In Figs. 11, 12, not shown, four pads are attached to the vehicle to produce high-pressure cushions, a V- shaped track being used to combine the supporting and guiding cushions. In Fig. 13, not shown, the guiding surfaces of the track slope inwards from the top to prevent the vehicle lifting off the track; and in Fig. 15, not shown, the main vehicle body is pivotally mounted on short end sections embracing the track. In Fig. 17, the vehicle has retractable wheels 90, 95 for manoeuvring the vehicle at a terminus, and has air brakes 96, a reversible propeller and brakes on wheels 90 to bring the vehicle to rest. Track brakes may also be applied. The vehicle may be propelled by a propeller, jet propulsion, or a linear induction motor, the energy for which may be picked up from a conductor rail by flexible members which can augment or replace one or more of the air curtains.

Title: Improvements in or relating to reversing mechanism for vehicles
IPC: B61C9/10
Filed: 1923-11-08
Abstract: 208,124. Renault, L. Dec. 6, 1922, [Convention date]. Reversing-gearing; controlling reversing-gearing. -Reversing gearing for motor vehicles, of the kind in which a double bevel gear wheel slides so that either wheel can engage with a driving pinion, is controlled by means which prevent the operating handle from being withdrawn except when the sliding gear is in either of its gear positions. On the axle is keyed a sliding sleeve 2 carrying bevel wheels 3, 4, either of which can engage the driving bevel pinion 6. The sleeve is moved axially by means of a screwed sleeve 8 which is rotated by a hand-crank 16 through gearing 17 and 12. Axial movement is limited by a flange 18 on the sleeve 8 which is locked in the limit positions by a pin 24 engaging a notch in the flange. When the crank 16 is pushed on its shaft 19, a collar 22 withdraws the pin 24 through link-work 26, 27, 28. To ensure that the sliding gears are always moved to the correct gear positions a disc 20 is so geared to the shaft 19 that it makes exactly one revolution during the shifting of the gears; a part of this disc is cut away to accommodate the collar 22 of the crank 16, so that this crank cannot be removed except when the reversing gears are correctly meshed. Also, the ignition circuit of the engine may be broken in intermediate positions of the gears to prevent starting with the gears incorrectly meshed.

A 4-pole contactor comprises an insulating block 13 of inverted L-shape having barriers 39 at intervals therealong, which barriers form between the two arms of the " L " cavities 14, 22, 31, 32 for the contact groups and extend above the horizontal arm of the " L " to form terminal cavities 43. Each cavity 14, 22, 31, 32 accommodates either a normally-open bridging contact and its fixed co-operating contacts (Fig. 3, not shown) or a normally closed bridging contact 12 and its fixed contacts 9, 10. The cavities are closed by a cover block 47 having barriers 48 formed at their edges 48a with channels 64 to mate with the lower portions 39a of the barriers 39. The contacts are controlled by four members 28 mounted at intervals along a bar 30 carried by a vertically-guided U-shaped member 60 pivotally connected at 61 to an armature 58 which is attracted towards an E-shaped core 55 when a coil 56 is energized. Thus in the instance of the contact 12, raising of the bar 30 causes a member 28 to abut the contact and open it against the bias of a spring 37, whilst in the instance of a normally open contact this is spring-mounted in a member 28 and thus moved to the closed position. A fixed member 62 slidably guides the member 60.

Filed: 1934-10-03
Abstract: 436,991. Applying adhesive tapes. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Metropolitan Sewing Machine Corporation; Nyack, New York, U.S.A.) Oct. 3, 1934, No. 28316. [Class 73] [See also Group VII] A seam-forming machine comprises a mechanism for stitching superposed main plies to form a seam, and mechanism for pressing adhesive tape to one or both faces of the seam. On a table 45 are located first and second sewing - mechanisms 46, 47 and an intermediate taping mechanism 48. all three mechanisms being operated by a common driving mechanism. The mechanism 46 has a trimming device 79 so that two plies can be stitched together and trimmed. The seam may be opened and flattened ready for the application of the tape. The multiple needle mechanism 47 then sews down the turned-over edges of the seam and the tape. The work, consisting of two superposed main plies 86, is guided from the seaming machine 46 to the taping mechanism 48 by a guide 89. This is in the form of a horn with a yoke 90 adapted to hook and pivot on a roller stud 72. It extends from the tape roller 71 and has a narrow finger fitting between the main plies. An adjustable stud 93 can regulate the spacing of the finger from the cloth plate to permit free passage of the lower ply. The guide has side walls with flared ends for opening and turning back the seam edges, ready for the application of the tape as it passes between the rollers 70, 71. The work is taped on one or both sides of the seam as desired and fed on to the twoneedle machine 47 which stitches down the tape and folds back the seam edges to form a seam such as shown in Fig. 30. The edgefolding device may be rendered inactive to produce seams such as shown in Fig. 31. The first-sewing mechanism 46 may employ a zig-zag stitch to produce the flat seams as shown in Fig. 32. The tape is supplied from upper and lower spools 122, 123 with suitable tape guides. For sewing and taping curved seams the sewing and taping mechanisms may be at different horizontal planes and out of line, the guiding means being modified accordingly. The three mechanisms are driven from a common electromotor, but means are provided to interrupt the drive between the mechanisms to compensate for slippage, feed irregularities, stretching of work, &c.

Title: Improvements in or relating to the preparation of oximes
IPC: C01B21/14
Filed: 1962-07-26
Abstract: Salts of ketone oximes are obtained by treating an aqueous solution of a bisulphite with at least one ketone to give the corresponding bisulphite compound in aqueous solution, reacting the bisulphite compound in an aqueous medium containing a water-soluble thiosulphate, with a water-soluble nitrite and passing sulphur dioxide into the aqueous medium at a temperature at or below 35 DEG C. until the pH decreases to below 5 so as to form hydroxylamine disulphonate, hydrolysing the disulphonate to the monosulphonate of the cation of the water-soluble nitrite and allowing the monosulphonate solution to stand until the salt of the oxime is formed.  The free oxime may be obtained by neutralizing the salt solution.  The process can be effected in a single operating phase and in the same apparatus, or the bisulphite compound may be precipitated and washed and then redissolved. It is preferred to effect the oximation step, as well as the Raschig reaction, in the presence of soluble thiosulphate.  In a preferred embodiment the soluble nitrite is replaced by nitrous vapours which are introduced into an ammoniacal solution of the bisulphite compound until the pH is 7.5 to 8.  Examples describe the preparation of the oximes of cyclohexanone and methyl isobutyl ketone.ALSO:Hydroxylamine di- and mono-sulphonate drivatives are made by reacting a bisulphite addition compound of a ketone, in an aqueous medium containing a water-soluble thiosulphate, with a water-soluble nitrile while introducing sulphur dioxide into the aqueous medium at a temperature no higher than 35 DEG  C. until the pH decrease to below 5 to form hydroxylamine disulphonate which is hydrolysed to the mono-sulphonate of the cation of the soluble nitrite. Alkali metal, alkaline earth metal and, preferred, ammonium nitrites are specified.  It is preferred to form the soluble nitrite in situ by introducing nitrous vapours into an ammoniacal solution of the bisulphite compound until the pH is 7.5 to 8.  In the examples ammonium thiosulphate is employed.
