Title: Treatment of filaments of elastomeric segmented copolymers
IPC: D01F6/72
Filed: 1965-05-12
Abstract: 1,104,667. Treating filaments of elastomeric segmented copolymers. CELANESE CORPORATION. 12 May, 1965 [26 May, 1964], No. 20000/65. Heading B5B. Filaments made from elastomeric segmented copolymers and exhibiting elastic stretch are stretched to such an extent that their length is increased by at least 150%, e.g. by 250 to 400% of their initial length, the stretching force is removed, the filaments are allowed to retract and the filaments are then heated to a temperature above 75 C. and below their softening point, e.g. to between 100 and 150 C. while wound on bobbins without being under stretching tension. The filaments may be made from a polyester-urethane copolymer and are preferably made from a blend of two different polyester-urethane copolymers of which one is considerably softer than the other. In an example, a 25% solution in a 91/9 methylene chloride/methanol mixture of a polyesterurethane copolymer obtained by reacting hy droxyl poly - (tetramethylene) adipate, butanediol-1,4 and diphenyl methane.p,p<SP>1</SP>-di-isocya. nate in a molar ratio of 1 : 1 : 2 is dry-spun to produce filaments which are drawn at room temperature using a stretch ratio of 4 : 1. The filaments are then completely relaxed at room temperature, wound on a bobbin without stretch and heated on the bobbin at 145 C. for one hour. The filaments treated according to the invention are composed of two principal types of segment alternating in the chemical chain, one segment, essentially amorphous, being derived from a low-melting point soft polymer such as an aliphatic polyester, polyether or polyolefine, and the other segment being derived from a hard high-melting point polymer such as a polyurea, a polyurethane or a polyamide. Generally, the hard segments comprise from 10% to 40% by weight of the copolymer.

Patent GB-357294-A (GB)
Title: Improvements in sheet collecting and folding mechanism
IPC: B41F13/60
Filed: 1930-07-03
Abstract: 357,294. Paper - folding m a c h n e s . GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Crafts, C. S. ; 645, North Lombard Avenue, Oak Park, Illinois, U.S.A.) July 3, 1930, No. 20226. Convention date, Dec. 24, 1929. [Classes 100 (i) and 100 (ii).] In sheet cutting, collecting, and folding mechanism comprising a collecting cylinder 10 having one or more sheet-supporting surfaces and carrying a folding blade or blades 41, 42 caused to coact with folding-rollers 33, 34 by a rotating slotted disc 60, the disc 60 can be set so that each blade operates each time it reaches the rollers 33, 34 or at intervals of two or more revolutions if the cylinder 10 is collecting. The shaft 37 carrying each pair of blades 41, 42 is as usual provided with an arm 47 having rollers 48, 49 at its ends normally running on a track 53, but engaged by diametricallyopposite cam slots 61, 62 on the disc 60 to cause the blades to engage the rollers 33, 34 at each revolution. In the arrangement shown, three blades 41, 42 are employed and it is therefore necessary for the disc 60 to have a speed-ratio of 3 to 2 relatively to the cylinder 10. Midway between the slots 61, 62 is a similar slot 63 and diametrically opposite the slot 63 is a cam part 64 which, when it is adjacent to the track 53, forms a continuation thereof. When therefore the cylinder 10 is collecting two sheets at a time, the disc 60 is set so that the parts 63, 64 act on the rollers 48, 49 so as to actuate the blades at alternate revolutions, i.e. the disc 60 is set in a position relatively to its driving gear different by 90‹ from the normal position for non-collecting. In one form of setting device, the disc 60 is fixed to a spindle 68 carrying a disc 70 secured to a driving gear 67 by bolts 71 passing into tapped holes arranged at 90‹ apart. In a modification the gear 66 driving the gear 67 is movable axially on its shaft out of engagement with the gear 67 to permit the spindle 68 to be turned through 90‹ by a handwheel, the gears 66, 67 then being re-engaged. Sheet-engaging pins 110 on the cylinder are operated by levers 113 carrying rollers 114 running in a cam-groove 115 on a disc 116 the shaft of which has a gearwheel splined thereon. For non-collecting, the disc 116 is held stationary by sliding the gearwheel into engagement with teeth on a fixed bracket, but when two sheets are to be collected the disc 116 is rotated at a speed-ratio of 3 to 2 compared with the cylinder 10 by moving the gearwheel into mesh with a gearwheel on the cylinder shaft.

Title: Apparatus for the interconversion of electrical energy and heat
IPC: H02M7/54
Filed: 1960-06-10
Abstract: 905,563. Refrigerators. STANDARD TELEPHONES & CABLES Ltd. June 10, 1960 [June 17, 1959], No. 20500/60. Class 29. [Also in Group XXXVI] An energy converter comprises a capacitor with a dielectric whose permittivity changes with temperature, coupled with means to charge the capacitor at a given temperature and means to apply heat to the capacitor and thereby change the dielectric permittivity which change varies the electrical energy stored in the capacitor and thereby converts heat energy to electrical energy or vice-versa. In a refrigeration system use is made of the fact that over a range of temperatures the dielectric possesses different specific heats in its charged and uncharged conditions. Embodiments are described for generating electric current (see Group XXXVI), and a system is described in which solar radiation provides the power to drive a refrigeration equipment, both the power generation and the refrigeration being by the method of this invention. Refrigeration.-Fig. 19 shows a system comprising capacitors 90 linked together to form two endless belts 85 and 86. The capacitors on belt 85 are charged as they pass brush 95, then heated as they pass from wheel 88 to wheel 97 by, e.g., solar radiation 96 and the increased energy is picked off by brush 98 and used to energize motor 99 to drive the second belt 86. The capacitors on this belt are charged at brush 101 and this charge increases the specific heat of the dielectric. Since the heat energy in the dielectric is constant an increase in the specific heat is accompanied by a decrease in temperature. The cooler capacitors pass into the chamber formed by the walls 103 and pick up heat from this chamber, on passing brush 104 the capacitors are discharged with a consequent decrease in specific heat and rise in temperature, the excess heat being radiated to the ambient atmosphere at 106. The load 105 it is suggested might be a battery which could be used to operate the driving motor for belt 85. Dielectric materials.-Ferro-electric materials such as barium titanate are said to be suitable.
Patent GB-1338431-A (GB)
Title: Method and apparatus for labelling
IPC: B65C1/00
Filed: 1971-04-19
Abstract: 1338431 Labelling apparatus SATO KENKYUJO KK 19 April 1971 [31 Jan 1970] 20550/71 Heading B8F A labelling apparatus includes a mechanism which separates labels from a backing strip by peeling back the strip relatively to the labels without the need for a direction inverting corner. The labels are dispensed from a label tape Da comprising a continuous strip of base material 39 and a continuous strip of label material adhering laminately thereon. At constant intervals incisions 48, 49 are provided in the tape defining label units. The tape, sliding on guide member 43, is moved towards a discharge opening 44 by a feed pawl 30 which engages the incisions, and the backing material is peeled off by roll 37. In the position shown in Fig. 3 approximately one half label length of backed label projects into a gap 56 with a slack portion d of backing material in a doubled back position beneath it. Pivoting a lever 3 clockwise about pivot 2 causes the feed pawl 30 to retract to the position shown dotted while roll 37 is rotated and draws in one label length of backing material. In this operation slack d is taken up and the backing peeled from the projecting half label to take up the dotted position. On release of the lever 3 roll 37 is stationed by a spring 46 while a return spring 4 causes the feed pawl to advance a label length of tape. The backing is thus peeled off the remaining half of the label and occupies the gap 56 as new slack d beneath the first half of the next label, as shown in Fig. 3. The tape D is fed from roll Da over guide plate 58 to the outlet 44. The hand lever 3, advances roll 37 by means of a pawl 42 acting on a ratchet fast with the roll and acts on a lever 6, pivoted at 5, which retracts the feed pawl and presses a printing device A on to each label before discharge. When putting tape into the device, bottom plate 51 opens, freeing spring 40 from roll 37 and allowing guide member 43 to swing down about pivot 43a for easy threading of the tape.
