IPC: B26D1/00
Filed: 1959-06-12
Abstract: 922,341. Cutting paper &c. sheets. C. G. MUNTERS. June 12, 1959 [June 13, 1958], No. 20179/59. Class 31(1). A method of forming sawtooth serrations along one edge of a plurality of thin sheets of material, such as paper, disposed in generally parallel superimposed relation, as for example in a gas and liquid contact pack as disclosed in Specification 837,601, consists in cutting out a plurality of serrations at least partly in one working operation by means of knives guided and moving transversely to and through the sheets intermediate opposite edges thereof, and simultaneously producing cuts in the individual sheets, the length of the cuts in the plane of the sheets being increased during the cutting operation with a component of movement corresponding to an acute angle of the cutting edges of the knives of between 10 and 25 degrees relative to the direction of movement of the knives. Apparatus, Figs. 2 to 4, for carrying out the method comprises a row of knives 34 mounted on a rail 48 carried by a vertically reciprocable bar 20 and a table 50 for supporting the sheets and provided with a slot 52. The knives are V- shaped in horizontal section and have V-shaped limbs provided with cutting edges 38, 40, Fig. 4. The sheets are held in position by two stops 54 adjustably mounted on pivotally mounted screw-threaded rods 56. Mounted above the table 50 is a stripping plate 62 provided with a slot corresponding to the slot 52. Each second knife 34 may be removed from the row mounted on the rail 48 in which case the sheets are advanced through the breadth of a knife at the end of a first cutting operation so as to cause the intermediate portions to be cut to the desired form of the serrations in a subsequent cutting operation. In a modification, Fig. 5, the knives are formed with flat blades 68 which each have oblique cutting edges on both sides and may be reinforced, as shown, by being provided at its middle portion with a double band. In this case, the knife blades will cut out one side edge 70 of the serrations in a first cutting operation. Thereupon, the sheets are inverted and the other side edge 72 cut out in a second cutting operation. The table 50 may be movable vertically instead of the row of knives or the row of knives and the table may be movable towards and away from one another.

Patent GB-204066-A (GB)
Abstract: 204,066. Signal Ges. Sept. 18, 1922, [Convention date]. Telephonic repeaters; magnetic instruments; microphones.-A magneto-microphonic amplifieris formed of two oscillatory structures coupled with one another and each tuned to the same frequency. The coupling may be of any kind such as mass coupling. In the amplifier, Fig. 2, the two structures are the armature 1, secured on a diaphragm 3, and the electrode 11, the two being coupled by the casing 4. The degree of coupling is preferably less than 20 per cent, and formulae are given for determining the degree of coupling in the case of a mass coupling. A capacity may be connected in series with the windings of the electromagnetic side of the amplifier and the electric circuit so formed may be tuned to a frequency in the neighbourhood of the mechanical resonant frequency of the telephone. The electromagnetic portion of the relay may be of the moving-coil type. The Specification as open to inspection under Sect. 91 (3) (a) also describes an instrument in which one microphone electrode is mounted directly on the armature of the telephone receiver. In a magneto-microphonic amplifier or in a telephone receiver used therewith the path of the magnetic flux is composed of laminations and is identical for the continuous-current flux and the alternating-current flux. The limbs of the magnet 6 are preferably inclined towards one another and the armature 1 is laminated. The volumes of the copper and iron are so adjusted that the iron and copper losses are equal. In the microphone the "elastic force" of the microphone filling is considerably less than the total "elastic force" of the whole microphone, the greater part of this force being in the diaphragm 10 on which the electrode 11 is mounted. The granules are enclosed by a felt ring 14. The coupling between the two structures of which the amplifier is composed gives rise to two coupling frequencies so separated as to cover a broad resonance region between them. This coupling may be electric coupling or friction coupling, and by the coupling of electrical circuits and further mechanical oscillatory structures therewith more than two coupling waves may be obtained. This subjectmatter does not appear in the Specification as accepted.
