Abstract: 592,768. Hair-curling appliances. WALTON, H. B., and WALTON, L. E. A. May 28, 1945, No. 13354. [Class 131] A hair curler comprises a frame, a resilient cover hinged to the frame, a base plate slidable on the frame, and means for detachably securing the cover and base plate together leaving the frame movable with respect to the base plate (e.g. due to the resiliency of the cover), the arrangement being such that, when the curler is open, there is provided a space through which hair can be inserted in the frame and in the form of a flat curl placed on the base plate, the cover and base plate being moved relatively to close the space and grip the hair at its roots and then being secured together to place the curl under pressure. In one form, Fig. 1, the cover 2 is formed with a lip 4 and is hinged to a wire frame 1 carrying a slidable base plate 5. The cover is slightly convex and is formed with perforations 7 to allow access of air, the plate 5 being formed with similar perforations 8 and a comb 6. After the hair has been inserted, the base plate is moved inwardly to grip the hair while the cover is closed, the plate then being moved outwardly to engage the lip 4 and place the curl under pressure. In a second form, Fig. 2, the comb is replaced by a curved portion 10, and the cover is formed with side portions 12 to prevent the curl slipping out sideways. In a modification, Fig. 7, the cover is locked in the closed position by a U-shaped slidable member 9 adapted to engage the lip 4. The cover and base plate may be made of metal, bone, horn, wood or plastic material and may be ornamented. According to the Provisional Specification, the base plate may consist of a slidable part and a fixed part, or two slidable parts, one adapted to engage the cover and the other formed with a comb.

Patent GB-133729-A (GB)
IPC: B21D53/50
Abstract: 133,729. Sundback, G. Sept. 9, 1918. Fastenings.-Fastener-stringers such as those described in Specifications 12261/15 and 114,629, [both in Class 44, Fastenings, Lock &c.], for use on corsets, money belts, footwear, clothing, stretchers and tents, and other straight closures, or on automobile curtain and other closures, with curved parts, are made by fixing a number of fastener jaws to the beaded edge of the stringer tape. The fastener members are punched and stamped out of a strip of metal, and the stringer tape is fed step-by-step so that the fastener members are fixed to it in spaced groups on a continuous stringer which can be cut up to allow pairs of groups to be used to form fastenings. Means are provided to increase and diminish the spacing at parts of the stringer which are to be bent to form the inner and outer parts of a closure curve. The metal blank or strip 1 from which the fasteners are made is fed between rolls 3 to a die member 10 in which the fastener is punched from it by a punch 22, the strip 1 being held tightly during punching by side guide-plates engaging wedges operated by pin-and-slot connexion with plates 14 connected to the punch head 15. The punching before being fed forwards is returned to its original place in the metal strip 1 by a sleeve 26 operated by a spring 27 and a rod 28. A scrap piece is subsequently removed by a punch 36 and the fastener shaped by a punch 38 and attached to the stringer tape 44 by side tools which press upon the side jaws of the fastener and are operated by mechanism from the punch-head 15. The residue of the metal strip passes through slots 54 and is cut up by knives 55 connected to the actuating-heads of the side tools. The stringer tape is fed through a spring tensioning-device 61 to holes in the die member 10 and punch holder from which it passes to a feed roll 63, 64, Fig. 18, and thence to winding-spool 65, Fig. 1. Mechanism is provided to control the feed roll 63, 64 for varying the space between the fastener members in the stringer tape, operation of this mechanism being effected by a ratchet-wheel 76 on a shaft 75 on which is splined a sleeve 77 having a cam clutch connexion 78 with the feed roll, so that when this sleeve moves longitudinally it accelerates or retards the motion of the feed roll. This longitudinal motion is produced by a sleeve 81 engaging a fixed screw 82 and operated by a double pawl and ratchet mechanism adapted to be put into and out of action or reversed by adjustable stops and mechanism. The length of the groups on the stringer is determined by giving the tape an increased feed at predetermined times, this being produced by a pawl 122 on a fription ratchet 119 operated by an arm 133 adjusted by a micrometer head 137 and acted on bv a spring 134 and a member 136 on the eccentric-rod 6 which operates the rolls 3. The parts are operated from the main shaft 8 by eccentrics &c.

Filed: 1973-03-22
Abstract: 1431557 Separating liquids RESEARCH FILTER UND PATENTFORSCHUNGS GmbH 20 March 1973 [20 March 1972] 13379/ 73 Heading BID In a method of separating oil from water, the polluted water is sucked from an antechamber through a filter by a pump and the purified water is then pumped into an equalising chamber, the pump being controlled by means dependent on the liquid level in the antechamber. In Fig. 8 the polluted water from antechamber 12 is drawn by centrifugal pump 21 through conduit 7, separating chamber 47 containing damping layer 49, and filter layers 107. Purified water is sucked through conduit 20 and chamber 65 and then passed into expansible equalising chamber 130. When the liquid level in antechamber 12 falls sufficiently the floatcontrolled magnetic switch is actuated to deenergise pump 21 and liquid passes from chamher 30 in a reverse direction through chamber 65 and filter layers 107 to clean the layers 107. If during the separating operation, oil layer 13 fills chamber 47 the ball valve 52 is closed preventing further passage of liquid to filter layers 107, vacuum switch 115 is actuated to deenergise pump 21 and float-controlled magnetic switch 120 is actuated to energise pump 21' and open valve 122. Liquid is then passed from the equalising chamber 130 by pump 21' through filter layers 107 to discharge oil through valve 122, this discharge being stopped when the water/oil interface in chamber 47 reaches the desired level. In Fig. 1 (not shown) antechamber chamber (10) also acts as a settling chamber and a conduit (7) supplying the polluted liquid to chamber (10) is provided with a ball valve at each end therof. In other embodiments the equalising chamber may be provided with a vapour lock at its discharge outlet and the filter housing may have a cover which carries all components except for the filter and housing. The filter material may comprise polyesters, polyisocyanates, polyurethanes or, polytetrafluoroethylene.

Title: Improvements in a method of and apparatus for stacking sheets
IPC: C21D9/46
Filed: 1937-05-14
Abstract: 486,698. Transferring sheets from one conveyer to another ; step - by - step conveyers. DODERER, W. May 14, 1937, No. 13715. Convention date, May 15, 1936. [Class 78 (i)] [Also in Group XVI] Sheets delivered singly in succession by one conveyer are lifted by arms until they are clear therefrom and then carried horizontally on the arms in the same direction as they have previously been moving until they arrive over a stacking position on a second intermittentlyoperated conveyer on to which they are deposited to form a pile fcr subsequent delivery bv the latter. In the construction shown, sheets delivered by a step-by-step conveyer from a furnace 1 abut against and swing a lever 7, thus moving an arm 9 to close a contact 10 and establish the circuit of the electromagnets 11. The guided platform 13 attached to the cores of the magnets is thus raised so that it swings pivoted levers 16 to rotate shafts 17 and thus causes arms 20 to swing up under the sheet and lift it from the conveyer. At the completion of this movement a member 22 on the top end of one core 21 operates a lever 23 to close a contact 24. This energizes an electromagnet 25 to swing a lever 28 and thus move the shafts 17 axially until the raised sheet is above the stack 32. In its limiting position the lever 28 operates a lever 35 and restores the lever 7 through the agency of the connecting cord 36. This opens the circuit at 10, so that the table 13 drops, and the arms 20 fall so that the sheet drops on to the pile 32 on the second conveyer. A counterweight 38 then restores the lever 28 and so slides the shaft 17 back to its initial position ready for the succeeding operation. Specification 409,034, [Group XII], is referred to. The Specification as open to inspection under Sect. 91 also included a modified apparatus for dealing with large sheets, the handling of which made it necessary to provide the shaft 17 with additional arms 60, Fig. 6 (Cancelled), having extensions 61 projecting horizontally into the furnace to support the rear end of the sheet. To enable these arms to pass into the furnace without fouling the wall 63, they had to be partly raised from their lowest discharging position early in the return stroke of the shafts 17. This was accomplished by providing two solenoids 11, 64, Fig. 11 (Cancelled), of which 11 was only de-energized by the opening of contact 66 by the lever 28 at the end of the outward stroke and re-established by the spring 67 as the return stroke commenced. The arms were thus held by solenoid 11 in a partly raised position from which they were moved to pick up the sheet by the energizing of solenoid 64. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to methods and devices for mercerising cotton fabrics
IPC: D06M11/38
Filed: 1930-05-05
Abstract: <PICT:0354312/IV/1> Goods to be mercerized are impregnated previous to their mercerization with the wash lye which is obtained from washing the mercerized goods in countercourse to their movement after mercerization.  The fabric 1 passes through the vat 2, in which the preliminary impregnation with wash lye is effected, between squeezing rollers 3, 4 to the impregnating vat 5, over rollers 7 to impregnating vats 8, 11 and squeezing rollers 9, 10, 12.  The mercerized fabric is then stretched transversely and longitudinally in the device 13, which incorporates breadth-stretching rollers such as are used in Mycock stretching devices.  The fabric passes to the wash tub 15, through which wash lye flows in countercourse to the direction of travel of the fabric, thence to the washing device 18 supplied with fresh water at 32 which is preheated in the coil 36 immersed in the vat 35. The wash lye from the vat 15 is thereby cooled in the vat 35, and passes via the valve 40 to the preliminary impregnating vats 2, thence to the filter 42, where it is either passed via the valve 46 to the recuperating reservoir 48, or is pumped at 44 to be re-circulated through the vats 15, 35, 2, depending on whether the fabric to be mercerized is initially wet or dry respectively.  The impregnating lye is circulated through the vats 11, 8, 5 via the pipe 31 and tank 24, which contains a cooling coil, by means of the pump 27.  The strength of the lye in the tank 24 is maintained by opening the valve 22 communicating with the reservoir 21 which contains concentrated lye.

Abstract: 1,058,525. Selective printing; ink-ribbon mechanisms. MONROE INTERNATIONAL, HOLLAND N.V. April 1, 1965, No. 13927/65. Heading B6F. Ink-ribbon mechanism.-An ink-ribbon 12 is fed from a spool 57 past a row of type-bars 7 by a feed drum 23 and pressure roller 27 which are rotated a certain amount determined by the number of type-bars used in printing that particular line. The drum 23 is rotated by a ratchet wheel 28 engaged by a pawl 29c on a slide 29. The slide is urged to the right, Fig. 1, by a spring 29f and is arrested by its upwardly projecting lug 29b engaging a control slide 14 which is cyclically moved to position one of several stepped side edges. This determines the amount of travel of the pawl 29c and thus controls the amount of feed. The control slide 14, if not operated at all, allows the pawl 29c to make a complete move and the ribbon 12 is fed the maximum amount. Intermediate positions of the control slide 14 are determined by the engagement of a projection 14c which stops the slide at the first type-bar it encounters. This is the highest denomination being printed and is the desired amount of ribbon feed required. The control bar is restored by mechanism 70-74 from the calculating machine pin carriage 53. After printing the ribbon is led to waste or cut off by a guillotine 35. 36 where the pieces fall into a bin 80. Type-bar machines.-The type-bars 7 are selectively operated via pinions 5 driven by transfer slides 3 set by a pin carriage 53 in the calculating machine. The bars have a slot (60) Fig. 2 (not shown) in which a stud (61) of a respective bell-crank (62) is received. The cranks are allowed to rotate by a shaft (64) to allow spring impression action but if the arms 66 of the cranks are blocked by a shoulder (14g) on the control slide the lost-motion device (67, 68) is effective and printing by those type-bars is suppressed.
