Title: Method and apparatus for perforating adhesive tape
IPC: G03D15/04
Filed: 1957-05-07
Abstract: 838,938. Perforating machines. WOOD, O. W. May 7, 1957 [May 7, 1956 ; Sept. 7, 1956], No. 14538/57. Classes 31 (2). [Also in Group XVI] A method of perforating normally tacky and pressure-sensitive adhesive tape for film splicing comprises forming a multi-ply strip having at least two layers of adhesive tape wherein the top and bottom surfaces of the strip are free of an adhesive coat and wherein the adhesive coat of each layer of tape is free of contact with an adhesive coat of each remaining layer of tape, and perforating the multi-ply strip so as to provide at least one row of perforations. As shown in Fig. 1, layers of adhesive tape unwound from rolls 1 to 3 and 5 to 7 and a protective strip unwound from a roll 4 are passed between squeeze rolls 9, 10 to form a laminated seven-ply strip 11. This strip is passed by means of pull rolls 12, 13 to a threading perforator unit, Fig. 2, comprising a perforating machine 14 where the strip is perforated to provide at least one row of spaced perforations. The perforating machine comprises a reciprocable punch 17, Fig. 3, having a row or rows of fingers, each row including two fingers 17<SP>a</SP> which act as pilot punches and further fingers 17<SP>b</SP> which act to perforate the strip; a die 18 and stripper 19 are also provided. The perforating unit also comprises a primary pull roll unit 15 and a secondary pull roll unit 16 which form loops 29, 30 in the multi-ply strip. The perforated strip 11<SP>a</SP> is passed from the pull roll unit 16 to a multiple wind-up unit (see Group XVI) where the layers of tape are stripped from the multi-ply strip.

Abstract: 439,846. Concentrating latex. NYROP, J. E., and KOEFOED, HAUBERG, MARSTRAND, & HELWEG AKTIESELSKABET TITAN, 86, Tagensvej, Copenhagen. May 20, 1935, No. 14718. [Class 70] [See also Group II] In the concentration of latex or the like by centrifuging, the latex to be concentrated is led to an outer zone of a separating chamber, and previously made concentrate is led to an inner zone of the chamber. Latex is fed to a centrifugal machine through a tube 8 whence it passes by passages 10, 18 to an outer zone of the separating chamber 4, while latex cream is fed by a tube 9 to an inner zone, the zones being separated at the bottom by an upstanding flange 5 to prevent eddies. Concentrate from the outer zone is absorbed by the cream in the inner zone, and is delivered by a channel 12, the skim passing through the channel 13. The separating chamber 4 and also the inlet channels 18, 11, may be provided with vanes, which may be radial or curved, e.g. logarithmic spirals. Specification 219,635, [Class 70], is referred to.

Convention dates, Nov. 13, 1939 and May 20, 1940. [Classes 22 and 87 (ii)] [Also in Groups VIII and XIV] A process for making dress forms from a living model comprises providing the model with a protective vest, assembling upon the vest and moulding to the contours of the model stretchable thermoplastic sheet material having a fabric base, the material being in the heated plastic condition, and allowing the material to cool and harden, whereupon the form is removed from the model. The material may be applied in overlapping sections, which unite at their edges, and may be removed, after hardening, by cutting, as along the line A, Fig. 3, the two sections thus formed being fastened by a slide fastener, or by adhesive tape or by heated strips 17 of the material, and the completed form being mounted on a stand. The fabric base of the stretchable thermoplastic sheet material may be flannel, felted cloth or a tubular knit fabric, and this base may be spread with a composition comprising vegetable wax, beeswax, rubber and resin ; in an example, a flattened tubular knitted fabric is impregnated and coated on both sides by drawing it through a molten bath comprising Candelilla wax, beeswax, rubber, resin or rosin or both (the resin may be polysterene, polyvinyl acetate, or polybutyl methacrylate); and a pigment such as oxide of zinc, titanium or iron. This composition softens between 125‹F. and 150‹F. and hardens between 135 ‹F. and 100‹F., and is " pinnable and self-healing. The Specification as open to inspection under Sect. 91 comprises the use as coating material of a composition which softens between 175‹F. and 180 ‹F. and hardens between 175‹F. and 100‹F. This subject-matter does not appear in the Specification as accepted.

Abstract: 876,043. Determining physical qualities of materials magnetic testing apparatus. VARIAN ASSOCIATES. May 4, 1959 [June 5, 1958], No. 15198/59. Classes 36 and 37. In gyromagnetic resonance apparatus, the polarizing field is made more homogeneous by forming part of the apparatus of a combination of paramagnetic and diamagnetic materials in such proportions that the magnetic susceptibility is the same as that of the surrounding media. As shown, the gyromagnetic sample is contained in a glass tube 1 which is rotated within a second glass tube 2 by means of an air turbine 4. The apparatus is provided with transmitter coils 13 fed with radio frequency, a receiving coil 9 and sweep coils 14 embedded in an aluminium body. Adjustable members 15 are provided to balance the coupling between coils in the absence of a gyromagnetic sample. The receiving coil 9 is wound from wire comprising a paramagnetic platinum core surrounded by an outer shell of copper as in Fig. 3 (not shown). Alternatively the wire may be formed by plating alternate layers of paramagnetic and diamagnetic material or by alloying such materials. A ratio of one part of platinum to 25 parts of copper results in a wire having the same susceptibility as the surrounding air. The coil 9 is attached to the tube 2 using a cement consisting of a specified epoxy resin to which is added 3.06% MnO2. The coils 9, 13 may be embedded in a ceramic comprising the required proportions of paramagnetic and diamagnetic material. Paramagnetic coils may be connected in parallel with the diamagnetic copper transmitter coils. The apparatus may be used to determine the'value of the magnetic field H or, by sweeping the field H over a range of values, spectral analysis of the sample may be undertaken. The invention may be applied to apparatus using a single coil in a bridge circuit or an oscillating detector. Reference has been directed by the Comptroller to Specification 789,238.

Filed: 1924-06-25
Abstract: 236,366. Rudeman, L. June 25, 1924. Composition fuel.- In making briquettes from peat or peat and peat earth, the water content, is first reduced to about 60-65 per cent and the peat is then mixed and agitated to open the peat cells with a substance containing phenols at 100 - 400‹ C., after which a binder is added and the mixture briquetted. Waste sulphite lye containing phenols may be utilized; heavy coal tar oils treated or not with chlorine or a tar product containing phenols may be used in addition to or instead of the lye. Sulphite pitch mixed or not with coal, wood or peat tar pitch may be employed as the binder. Coal or coke dust, sawdust, furnace residues &c. may be added to the peat at any stage before briquetting. In an example 10 per cent of lye and 1 per cent of oils or tar product are mixed with finely ground pre-dried peat, and after treatment the superheated mass is subjected to a pressure of 100-400 atmospheres together with a binder consisting of 3 per cent of hard coal tar pitch.
