Title: Improvements in or relating to friction clutches, more particularly for hydraulic transmission gears
IPC: B43M5/02
Filed: 1934-05-17
Abstract: 421,778. Friction clutches. WACH, H., 57, Seestrasse, Kilchberg, near Zurich, Switzerland. May 17, 1934, No. 14951. Convention date, May 17, 1933. [Class 80 (ii)] [See also Group XXIX] In friction clutches immersed in a fluid and for use between parts which are adapted to run at different speeds through alternative transmission when the clutch is open, after declutching, one of the members is disengaged from its shaft, preferably by the axial movement of the parts of a claw clutch. The invention is especially intended to be used in conjunction with hydraulic clutches, e.g. in the F÷ttinger gear, as described in Specification 409,378, [Group XXIX]. In that case the friction clutch is outside the casing of the transmission gear, but when constructed according to the present invention may be located inside without producing objectionable eddies in the contained liquid. The clutch comprises a disc x splined to the turbine runner b and adapted to be clamped by springs v between a member w fast with the ribbed part l<1> of the casing l and thus with the shaft z, and a member w<1> positively driven by the shaft z through the left hand part of the casing, but slidable axially in the casing. To disengage the clutch a rod t, inside the driven shaft y, is pushed by a pedal against a ring s upon the periphery of which rests a lever r. As the lever r rides up the bevel s<1> it presses upon the member w<1>, and removes the pressure of the springs v. When the lever r rests on the cylindrical part s<11> of the ring, the clutch rod and pedal are relieved of thrust. In order that the disc x may rotate with the members w, w and so avoid eddies, it is coupled with the runner b by a claw coupling g, Fig. 2, and is formed with a flange h, engaging a flange i on the member w<1>, which when it moves to the left, takes with it the disc x and disengages the coupling g. In a modified construction, Fig. 3, in which only a slight movement of the springs is required, a flanged sleeve or bush o is interposed between the disc and runner and splined to the disc. When the ring a moves to the left a dog k fast on the ring engages the bush and disengages the coupling g to free the disc. A spring m is provided between the disc and bush to close the coupling g prior to the action of the springs v.

Abstract: 873,349. Bottle carriers. BRADSTREET & SONS Ltd., E. J., and BURKE, P. E. Nov. 5, 1957 [May 10, 1957], No. 14984/57. Class 18. A cardboard carrier carton for bottles or the like is folded up from an elongated creased blank to form a base 6 provided with upright partition panels 7 which divide it lengthways into two, sides 5 and marginal bent-up end walls 10. In one embodiment, a blank scored and punched as in Fig. 4 is bent to form the carrier shown in Fig. 3, the sides 5 being wire stitched together near finger holes 11, and the partition panels 7 being stitched together. The holes 11 form a finger grip, holes 12 allow bottle necks to protrude while holes 13 allow inspection of the labels. In another embodiment, Figs. 5-8 (not shown), extra crease lines are incorporated so that portions of the sides form a roof (parallel to the base 6) from which extends upwardly at rightangles the hand grip area; the panels 7 are elongated to extend between the two handgrip portions, and the holes 12 and 13 are eliminated. In both embodiments, creases 8 and 9 define marginal portions of the base which are bent up to form end walls or guards to prevent dislodgment of the bottles.

Abstract: 494,357. Control of D.C. motors. TUSTIN, A. May 31, 1937, No. 15015. [Class 38 (iii)] Varying E.M.F.; field control.-One or more traction motors 6, 7 are supplied from a generator 1 driven by a motor 3 energized from a supply 4 for the vehicle, and the motors have fields 10, 11 energized in accordance with the difference between the voltage of a variable voltage exciter 15 for the generator and another voltage of fixed or substantially fixed value, so that during acceleration the excitation of the motors is decreased simultaneously with increase of the generator excitation and voltage. The fields 10, 11 may be connected in series with the exciter 15 across an auxiliary generator 12 which supplies auxiliary apparatus on the vehicle with constant voltage. The motors 6, 7 may have series fields 8, 9 additional to the fields 10, 11, and reversing switches 21, 22, 23 for the motor fields are provided. The field 17 of the generator exciter 15 is supplied and controlled from a potentiometer 18 connected across the generator 12. The generator 12 may have a voltage regulator 14 whereby its voltage is maintained constant, but it is sufficient if the voltage of the generator 12 has a voltage which varies less than the voltage of the exciter 15.

Title: Improvements relating to safety devices for hydro extractors
IPC: B04B7/06
Filed: 1925-06-10
Abstract: 257,684. Loudon, A., and Jack, W. June 10, 1925. Casings; safety stopping devices. - In a hydro-extractor, a member associated with one of the rotary parts is brought into operation simultaneously with the disconnection of the driving means, and releases a lock on a bolt holding the cover closed. The basket 3 is driven by the belt 5 from a pulley 4 rotated with the fast pulley 4'. The basket spindle carries a drum 8 above which is arranged a heavy brake shoe 7 normally held clear of the drum by a pair of lever arms 10 engaging an annular shoulder 11 on the shoe. The end 15 of a lever 15, 16, pivoted between its ends, is connected to a forked member 17 which acts as an interfering device engaging a nut 18 on the bolt 19 of the cover lock to maintain the bolt shoe. The other end 16 is held clear of the brake shoe by a projection 10<1> on one of the arms 10. The brake is applied by movement of the handle 13 which allows the shoe to drop on the drum 8; the shoe is consequently rotated in opposition to the stress of the compression spring 27. This brings the grooves 21, 21<1> into register with the arms 10 and the movement of the handle 13 can be continued to move the belt 5 on to the loose pulley 4". At the same time the projection 10<1> enters a recess in the lever 16 and permits the lever to rock by gravity until it engages the rim 20 of the shoe. When the machine stops the spring 27 forces the brake shoe back to its original position and the lever 16 enters the groove 21, thereby causing the member 17 to drop so that the bolt 19 is unshot and the cover is raised under the action of the compression spring 28. The brake shoe may have extra grooves for use if the drum revolves in the reverse direction.

Abstract: 805,338. Switches retained set and freed mechanically HOLLINS, J. R. May 15, 1956 [Oct. 19, 1955], No. 15112/56. Class 38 (5). [Also in Group XXXVIII] A switch assembly for flashing lights on vehicles (see Group XXXVIII) comprises a combination of a pivoted operating lever for selectively energizing lamps on one side of a vehicle with a rectilinearly moving operating member for simultaneously energizing lamps on both sides of the vehicle, characterized in that the rectilinearly moving operating member is biased to its ineffective position and when operated with the pivoted operating lever in its neutral position is latched until the pivoted lever is moved to a selected side whereupon the latch means is released. The switch assembly comprises a housing 15 with covers 11, 12. The base 15 carries screws 18 for tightening a strap 14 whereby the switch is secured to the vehicle steering column. An operating lever 40 is pivoted by means of trunnions 22 and 68 and carries an indicator lamp PIL opposite an aperture 70 to illuminate one of three coloured lenses 65 according to whether the lever 40 is in its neutral position or moved to either side thereof. A spring 31 urges a cam 20 to engage notches 71 and releasably latch the lever 40 in its selected position. Two rectilinearly movable contact-carrying members 90 engaging flush contacts in an insulating plate 30 (Fig. 2) are urged against wall 27 of housing 15 by springs 92. Each member 90 has an upstanding abutment 110 projecting through a slot 33 in housing 15 (Fig. 1). When lever 40 is moved to either side of its neutral position shown, one of the wings 75 thereon engages one abutment 110 to move one of the members 90 to its operated position, compressing the associated spring 92. A second operating member 50, shaped as shown in Fig. 8, is rectilinearly movable as indicated by the arrows in Figs. 1 and 2. When operator 50 is pulled outwardly both contact-carrying members 90 are moved to their operated positions by ears 80 engaging abutments 110, and the operator 50 is latched in this position by the tip 82 of a leaf-spring 85 which rides over a lip 73 on lever 40. When lever 40 is moved to either side of its neutral position the lip 73 moves away from spring tip 82 and allows operator 50 to return to its " off " position under action of the two springs 92 pressing on members 90. Specification 680,550 is referred to.

Abstract: 1,109,561. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 18 May, 1966 [9 April, 1965], No. 15131/65. Heading B7K. In an air cushion vehicle having the cushion space bounded by side-walls 12, each side-wall comprises rigid portions 12a, 12b disposed fore- and-aft of a portion 12c formed from flexible sheet material. The forward and aft ends of the cushion space 13 are defined by hinged flaps 14 and each flexible portion 12c may be in one piece or, as shown, a plurality of individual strips laced together. In operation over water, the rigid portions 12a, 12b are partially submerged and at higher speeds the portion 12c may be partially retracted to reduce drag. To this end a roller 21, operated from motor 24, has a number of cords 26 attached thereto at spaced intervals along its length and each cord is secured to the lower edge of the flexible portion so that operation of motor 24, either manually, or automatically in response to a speed-sensing device, would raise or lower the skirt. A fan F delivers air to the cushion plenum chamber and a water screw 18 is mounted on each portion 12b and is driven by an internally-housed shaft S, wheels 16 being provided to enable the vehicle to negotiate ramps. For such land operation, propulsion is by an air propeller unit P. The flexible side wall portions and the front wall may be formed of individual contiguous inflatable U-section strips. A wall constructed as shown in Fig. 1 may be used to divide the plenum chamber laterally.

Title: Process for reducing the water imbibition of cellulose hydrate products
IPC: D06M11/05
Filed: 1943-09-17
Abstract: The water imhibition of cellulose hydrate products such as regenerated cellulose fibres, filaments, yarns, films, and the like, is reduced by subjecting them, while they contain between 30 and 40 per cent of water, to the action of heat in a closed vessel.  The moisture content is adjusted to the required proportion by centrifuging the wet products until they contain about their own weight of water and then drying in air at room temperature or by passing a current of warm air through them, or the air-dry products containing about 11 per cent of moisture may have water added to them until they have the required proportion. The heat treatment may be effected at temperatures of 60-160 DEG  C. The water imhibition, determined by immersing the products in distilled water at 20 DEG  C. for 15 mins., followed by centrifuging for 3 mins., may be reduced to about half of that of the untreated material.  In an example, skeins of viscose artificial silk yarn are centrifuged and then allowed to dry by exposure to air until the moisture content is about 35 per cent on the weight of the moist yarn.  The yarn is then placed in an air-tight vessel and maintained at 150 DEG  C. for 30 mins.  The yarn is then removed and drying is completed.  Specification 201,526, [Class 2 (ii)], is referred to.
