Title: Improvements in and relating to filter plugs for cigarettes, cigarette holders and like smokers' appliances
Inventor: RUBACK SYDNEY
IPC: B01D39/18
Filed: 1957-11-26
Abstract: A filter element for a cigarette or cigarette holder, comprises bulked filaments which, whilst their surfaces are rendered adhesive by a solvent plasticizer, are formed into a rod and enclosed in a paper tube coated internally with a material which is also rendered adhesive by the plasticizer and to which, as well as to each other, the filament ultimately bond.  The filaments are of a thermoplastic material, e.g. polyacrylonitrile, polyvinyl acetate, polyvinyl acetate/chloride polymer or crimped secondary cellulose acetate, the coating is a thermoplastic synthetic resin e.g. vinyl acetate or a vinyl-acetate-vinylchloride copolymer, and the plasticizer may be triacetin or dimethyl glycol phthalate. Bonding may be effected by heat or by allowing the wrapped filaments to remain for up to 24 hours at room temperature.  The paper tube may have a lapped joint which, upon pressure by a heater bar thereon, seals due to the thermoplastic coating, which may be locally thickened.  Quantitative process examples are given.  Reference is made to the use, said to be known, of a strip or strips of liquid adhesive on a wrapper to stick it to cellulose acetate filters of kinds described in Specifications 744,449 and 765,963.

Title: Improvements in ironers
IPC: D06F77/00
Filed: 1934-12-28
Abstract: 432,002. Ironing-machines. FOSTER, E. E., 2501, Enfield Road, Austin, Texas, U.S.A. Dec. 28, 1934, No. 37164. [Class 138 (ii)] The iron 1, Fig. 1, is rotatably and slidably supported on an arm 4 articulated to another arm 5 secured to a hollow standard 26 rotatably and slidably supported in a casing 27 by ball bearings. In the form shown in Fig. 5 wherein the ironing-pressure is applied by a spring 41 which before the iron is lowered into engagement with the work counterbalances the weight of the iron, the lower end of the standard 26 is rotatably mounted in a carriage 30 having rollers 31. An arm 34 is pivoted about the roller axis and a bellcrank lever 37, 38 is fulcrumed in its free end. One end of the bell-crank is pivoted to a link 39 which is pivoted to an adjustable fixed support 68 and the other end of the bell-crank is connected to the spring 41 of which the other end is anchored on the arm 34. In the position shown the iron is raised above the work support and the spring 41 counterbalances its weight until it is depressed into contact with the support when the axes 32, 68 coincide. A slight finger pressure on the iron handle rocks a link and lever system housed within the arms 4, 5 to draw upwardly a rod 58 secured to a lug on the arm 34. During the following angular movement of the arm 34 the force of the spring acts so as to draw the iron into effective ironing engagement with the work. In the form shown in Figs. 7 and 12 the iron is counterbalanced by a spring 74 and the ironing pressure is applied by energization of a solenoid 84. A plunger 87 secured to the armature 86 is locked to the carriage 73 secured to the hollow standard 26 by means of a wedging cam 97 which is moved into wedging position whenever another solenoid 85 is energized. Energization of this solenoid is effected by the manually controlled slight downward movement of the iron 1 relative to the arm 4, on contacting with the work, closing contacts 113, Fig. 12, in the solenoid circuit through a lever 111 against a spring 114. The degree of ironing pressure is controlled by the strength of current in solenoid 84 and this is manually adjusted by rotation of a handle 106 to raise or lower a lever 109 controlling a rheostat 110, 112 in the circuit of solenoid 84. In the form shown in Fig. 10 two solenoids 117, 118 having opposite effects are used, the solenoid 117 being energized to counterbalance the weight of the iron and solenoid 118 being energized to apply the ironing pressure. Alternatively, fluid-pressure operated means may be substituted for the solenoids.

Title: Improvements relating to mechanism for the conversion of vibratory motion into rotary motion
IPC: B06B3/00
Filed: 1928-12-20
Abstract: 325,635. Stringer, H. L. Dec. 20, 1928. Machinery, utilizing inertia to obtain movements in.-An apparatus for converting vibratory movement into undirectional rotary motion comprises two or more flexible members, tensioned by springs, passing around a member to be driven, and connected at their ends to a weighted member having movement relative to the axis of rotation of the driven member. The flexible members are so arranged that, starting at the end at which the springs are attached, they all encircle the driven member in the same sense. The device as shown in Fig. 1 may be employed for advertising. One end of a drum 1 is carried in a bearing 6 allowing of universal movement and the other end is resiliently supported in a bearing 4 by a spring 5 attached to a fixed casing. A pulley 7 secured to the drum is encircled by cords 8, 9 connected to spring 12, 13 attached to the casing. In the embodiment shown in Figs. 3, 5, the device is used to wind a clock spring and is supplemented by a mechanism which transmits the drive at fixed intervals. The cords 8, 9 with their springs 12, 13. pass round a pulley 7 and are attached at their ends to a vibrating weight 26. Secured to the pulley is a casing 34 having pinned thereto one end of a clock spring 36, which is itself secured to a sleeve 35. A spindle 37 is pinned to the sleeve and also to a disc 38. The upper end of the sleeve 36 has a claw 39 engaging one of two stops 40 on a plate 41 which is bored eccentrically and receives an eccentric boss 42 formed on the casing 34. As the pulley rotates, the plate is moved from side to side, releasing the claw, and allowing the drive to be transmitted each half revolution. An embodiment shown in Figs. 6, 7 for rotating a motor-car mascot comprises three cord members 20, 21, 22 with their springs 20<a>, 21<a>, 22a attached to the radiator cap M, and passing round a weighted pulley 19 rigidly secured to the mascot 14 by a spindle 15 with a hemispherical collar 18 allowing of vibration of the pulley 19 in all directions. In an alternative construction, the pulley is fixed, and a casing carrying the mascot is free to vibrate and to rotate on a pivot mounted on the pulley. In the construction shown in Fig. 10, the weight 26, is carried by a lever pivoted at 27 and connected by cords 29, 30 with springs 31 and 32 passing round the driven member 25 to a fixed casing 33. When the weight is rocked to the right, the cord 39 and spring 31 are extended, causing rotation in the direction of the arrow, and on rocking the weight to the left, the cord 30 and spring 32 cause a further rotation in the same direction. Specifications 193,997, and 310,160, [Class 139, Watches &c,], are referred to.
Patent GB-904624-A (GB)
Title: Fluid pressure regulators
IPC: G05D16/10
Filed: 1958-11-25
Abstract: 904,624. Valves. MAROTTA VALVE CORPORATION. Nov. 25, 1958 [Nov. 27, 1957], No. 38008/58. Class 135. A spring-closed valve member 32, Fig. 1, of a pressure regulator, balanced with respect to pressure in inlet 22 and seating at 34 to control the supply of pressure fluid to the outlet 24 and to a pressure gauge port 26, is controlled by the pressure of the fluid in the outlet acting on the adjacent face of piston 60, the other side of which is subjected to a normally fixed but adjustable loading pressure. Apparatus for controlling this normally fixed but adjustable pressure comprises two valves 104, 192, Figs. 1 and 5, connected in series with valve 104 supplied with pressure fluid through passage 92 from inlet 22 and valve 192 leading to chamber 74 surrounding piston 60, and a spring-loaded variable bleed to atmosphere is provided in passage 190 joining the two valves. The stems 140, 204 of the valves 104, 192 are actuated by a wobble plate 144 operated by a rotary handle 160 which is spring centred at 170 so that both valves are closed and a constant pressure is trapped behind the piston. To alter the regulated pressure the wobble plate is arranged so that rotation of the handle 160 in one direction causes both valves to be opened and the loading pressure to be increased until the desired outlet pressure recorded on the gauge is reached after which the valves are closed by the spring centring of the handle. Alternatively, the loading pressure and outlet pressure may be reduced by rotating the handle in the opposite direction so that wobble plate 144 only opens the valve 192 to vent fluid to atmosphere through bleed 224, which closes with increased pressure to maintain a constant flow until the new desired outlet pressure is reached. When reducing the loading pressure and hence outlet pressure, outlet pressure may be relieved through passage 223 in the valve member leading through a passage 236 to atmosphere by virtue of the plastic insert 62 in the end of piston 60 being lifted from a seat at the end of valve 32 due to the outlet pressure acting on the end of a piston. The loading pressure may be rapidly reduced by turning the handle to the limit of the venting movement when a further valve, not shown, is operated by cam action to vent chamber 74 directly to atmosphere. A safety valve 82 may be provided to prevent excessive build-up of loading pressure. The control valves 104, 192 are similar and comprise, Fig. 2, a closure part 114 seatable on a resilient seating 116 and a throttling part 132 with a throttling groove 134.

Title: Infant restraining device for use in vehicles
IPC: B60N2/28
Filed: 1974-08-30
Abstract: 1478323 Infant bed for vehicles WINGARD Ltd 30 Aug 1974 38009/74 Heading A4J [Also in Division A5] The arrangements for securing an infants cot or bed in a vehicle are such that under rapid deceleration the cot pivots to the position shown in Fig. 5, whereby the impact forces on an infant may be spread over a large body area and whereby the head and body are both supported. In the Fig. 5 embodiment the cot is retained by a vehicle seat belt, e.g. the lap strap, 44 passing round the cot body. The guides 48, 50 ensure that in the normal position of the cot the path taken by the strap 44 passes above the centre of mass O of the cot with a child in it. The curved portion 34 ensures easy rotation on impact. In the Fig. 6 embodiment (not shown) each end of the cot is provided with a pivotally mounted stirrup, the retaining strap being threaded through a slot in each stirrup. The points of pivotal attachment of the stirrups are above the centre of mass of the system so as to ensure clockwise rotation of the cot upon sudden deceleration. In a modification Fig. 11 (not shown) the  stirrups 94 are secured at two points to the cot, at least the lowermost of the arms of the stirrups being rendered extensible, e.g. by concertina folds. Thus on impact the lower arms stretch to allow rotation of the cot while absorbing some of the force. A modified stirrup Fig. 12 (not shown) is rendered deformable by thinning of one of the arms. In a further embodiment the cot comprises an elementary frame secured to the vehicle via a strap engaging pivotally mounted stirrups in the manner of the (Fig. 6) embodiment. The child containing portion is composed of a hammock like cradle of flexible material suspended from rods extending along the front and rear top edges of the frame. Thus not only can the framework rotate upon impact, but the cradle will swing within the frame. If desired the cradle can incorporate pleats which are released under impact to absorb some of the force. The cot per se may comprise a rigid, e.g. plastics, shell with internal padding and reinforcing end plates for attachment of the stirrups &c. The shell may be reinforced by an internal rigid frame of rods.
