Title: Improvements in or relating to apparatus for sinuously looping sheet material
IPC: C01G21/02
Filed: 1933-08-11
Abstract: 413,508. Corrugating non-metallic sheet material. GOODRICH CO., B. F., 342, Madison Avenue, New York, U.S.A. Aug. 11, 1933, No. 22456. Convention date, Sept. 12, 1932. [Class 141.] In a looping or corrugating of sheet material to form a cellular structure, the sheet of material is displaced alternately by rods to opposite sides of its straight run so that it becomes looped round the rods with the meeting edges of the loops in contact with one another to form closed cells, the rods subsequently being withdrawn by an axial sliding movement and delivered for re-use while the looped material passes to deliverymechanism. The invention is applicable specially to the treatment of sheets of unwoven fibres with a binding agent, such as unvulcanized rubber composition, cellular articles made therefrom being subsequently fixed by vulcanization. The sheet of material A, Fig. 3, passes round the tensioning-roller 14 and guide rollers 13 to a vertical run between two guides 17, Figs. 3 and 7. At the top of these guides a rod B is lfted by a plunger 41 over the lip 37 of the rod-storage-tray and is delivered to hooks 39 from which it is picked up by a swinging arm 51 with fluid-operated pincer jaws, and deposited in the left hand column of rods B, taking the sheet with it in the process. Immediately afterwards, a similar appliance on the opposite side deposits a rod in the right hand column thus forming a second reversed loop in the material. This process is continued indefinitely, the weight of the rods gradually feeding the sheet downwards against the spring pressure of the bearer members 25. At the lower end, the lowest rods rest on supports beyond the edges of the sheet and the bottom rods of each pile are withdrawn simultaneously in opposite directions by means of claws 107, Fig. 1<b>, on endless chains 103 which engage collars at the ends of the rods. At the end of the run, the rods are thrown off the chains laterally down shoots 39, Fig. 5, to a point where they are picked up by hooks 112 on endless chains 111 and thence are delivered to elevated shoots 115 which lead to the upper runs of conveyers 116 leading to the respective rod storage trays.

Abstract: 252,949. Konstas, A. S., and Soc. Anon. Industrielle des Matieres Grasses et Savons Velos. Sept. 8, 1925. Purifyinq fatty and mineral oils. - In the separation of mixtures of soap and oils nr fatty substances resulting from the neutralization of the oils &c. in which the soap is dissolved and removed by a solvent, such as alcohol or methylated spirit, which is miscible with water or with aqueous soap solution, but in which the oil &c. is practically insoluble, the soap is recovered from its solution in the volatile solvent by causing the solution to circulate in the presence of a boiling solution of common salt, the precipitated soap being collected after distillation of the solvent. The salt solution is contained in a vessel A divided into compartments C and D by a partition B having apertures E in its lower end, and that in the compartment C is kept boiling. Soap solution is supplied gradually to the compa,rtment C bv a pipe F and valve G, whereby the solvent is vaporized and passes by a pipe L to a condenser, whilst the soap is carried over the partition H bv the circulating salt solution and collects on the surface of the solution in the compartment D. The invention may also be applied to the separation of mixtures of soap and mineral oils.

Convention date, Aug. 8, 1929. [Class 73.] Apparatus for applying sealing bands to tins &c., wherein the tins &c. are moved towards an adhesive strip between guides in such a manner that the strip is applied partially round the tin, leaving a portion free, is characterized by the fact that the strip is drawn from a reel by moving gripper tongs &c., is coated with adhesive, or moistened, as it moves, and is brought into the correct position for application, but is not severed until it has been partially applied around the tin. The band is drawn from a reel 1 by a reciprocating gripper 3 which grips the band in the slotted mouthpiece 4 and draws it to the position shown, the band being gummed, or moistened, by a roller 51; backward movement of the band is prevented by a spring presser 6. The band lies in a guide channel 8 being retained therein by automatically-controlled fingers 9. The tins 11 are fed along a passage 12 as far as a stop 13 when a ram 14 descends and presses the leading tin into contact with the band resting on a lower ram 15. Further descent of the ram 14 conducts the tin between guides 20, 21 fitted with rollers 22, 23 which apply the band to three sides of the tin. The tin is then pushed into a horizontal passage 25 to apply the band of the fourth side, the band being severed by knives 26, 27 immediately before the operation of the pusher 24; the short end of the band is applied to the fourth side of the tin by a wiper 28. Specification 324,171, [Class 73, Labels &c.], is referred to.

Abstract: 736,291. Electronic switching circuits; radio receiving circuits. BRITISH COMMUNICATION CORPORATION, Ltd., and HEFTMAN, T. S. Sept. 13, 1951 [Sept. 13, 1950], No. 22553/50. Classes 40 (5) and 40 (6). Remote control apparatus for selecting tuned circuits in radio apparatus comprises a plurality of rectifiers connected in series with the circuits and a manually-operated switch means to bias the rectifiers to the conducting or the non- conducting state. Fig. 1 shows an intervalve coupling in a radio receiver, in which tuned circuits 13 and 14 are connected through rectifiers 19 and 30 respectively to the circuit connecting the output of valve 10 to the input of valve 36. Remote control switches 22 and 33 associated with bias supplies 26 and 27 enable either of the rectifiers to be made conducting and the other non-conducting, so that either of the tuned circuits may be selected to be operative in the intervalve coupling circuit. Capacitors 20 and 31 are provided to neutralize the capacitances of rectifiers 19 and 30, thereby reducing the coupling when the rectifier is non-conducting. A modification is described in which only one bias source is used in conjunction with a reversing switch. The rectifiers may consist of germanium diodes for low voltages, or thermionic diodes for higher voltages.

Abstract: 1479316 Acoustic measurement of physical properties A ROSENCWAIG 17 June 1974 [15 June 1973] 22963/74 Heading G1G A sample in contact with a fluid is investigated by irradiating the sample with intensity-modulated electromagnetic or particle radiant energy, and detecting periodic rarefaction/compression variations in the fluid caused by the sample on irradiation, the detector including a transducer and a resonant chamber which produces no such variations on irradiation. In the Fig. 1 embodiment light of a colour selectable by control 58 and mono-chromator 14 is chopped at 16 at a given frequency then directed, by beam-splitter 20 and mirror 24, on to similar cells 22, 26 containing respectively a test sample 32, e.g. a powder or a biological specimen, and a reference black body, carbon black or gold black. Absorption of light by the sample results in a cyclic flow of heat between the sample and surrounding gas, cyclic expansion of the sample, and hence the production of acoustic energy of a frequency equal to the chopping frequency. This energy is picked up by an electret microphone 44 on a perforated resonator tube 38. The microphone outputs of the two cells are processed to give D.C. signals S1, S2 proportional to the respective detected acoustic intensities. The radio S1/S2 is formed at 54 and plotted on X-Y recorder 56 as a function of the light colour. This ratio represents a normalised absorption spectrum from the sample, the effects of variations in the light source output with wavelength having been removed by use of the S1 signal. Examples are given of spectra from various samples. The light source may be a xeron lamp, a laser, or a series of LEDs; or higher energy photons, e.g. from a synchrotron or U.V. lamp, may be used. The reference cell 26 and divider 54 may be omitted; in which case voltage signal S2 is converted to a proportional frequency which is fed to a multichannel pulse analyzer, the digital spectrum provided by the analyzer is recorded on tape, and normalization is effected by a computer which divides the spectrum by that previously obtained from a carbon black standard.
