Title: Terminals for fsk systems
IPC: H04L5/14
Filed: 1974-07-31
Abstract: 1448164 Data transmission; FSK systems WESTERN ELECTRIC CO Inc 31 July 1974 [6 Aug 1973] 33715/74 Heading H4P A duplex FSK system having different bands for transmission and reception has means for discriminating between mark and space frequencies in the bands, the band of operation being determined by a signal representative of one of mark/space frequencies in desired band of operation. Preferably output from master oscillator 17 is not an integral multiple of at least one frequency, provided by a division circuit which utilizes a jittered counting ratio, i.e. shift register arrangement which simulates a counting system. A terminal 11, e.g. teleprinter or computer, either of which may include a display, may transmit in lower I.F. band 1 or higher I.F. band 2, selection being made by switches 20, 22 which I.F. is divided at 23 to produce in switch position shown, band I say 1270 (mark) and 1070 (space) frequencies by division to a control office (not shown) which may have switching facilities and thence to a slave station B from which 2225 (mark) and 2025 (space) frequencies may be transmitted to master station A. These are applied through a band rejection filter (not shown) providing isolation from the other frequency band and thence to a commutating capacitor unit CCU also receiving through switch 22 a continuous frequency in band 2 determined by a continuous "1" signal 21. To interchange the roles of terminals A, B, switches 20, 22 are reversed so that signal 21 is applied to 18 and hence a lower frequency in band I is supplied continuously to the CCU discriminator. The discriminator is described in greater detail with respect to Figs. 2 and 3 (not shown), and gives "in phase" outputs for the higher (mark) frequencies of each pair and antiphase outputs for the lower (space) frequencies which are applied through filters (41, 42) and limiters (43, 46) to an exclusive-OR (47) before passage through a further CR filter coupled amplifier arrangement to a utilizing device.

Abstract: 471,876. Band - width reduction. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Dec. 10, 1935, No. 34222. Void. Convention date, Dec. 10, 1934. [Class 40 (iv)] [Also in Group XL] The band width of a modulated carrier wave is reduced by utilizing fractions or sub-multiples of the signal frequencies as modulating frequencies without altering their time duration. As shown in the Figure, signals from the source N are fed to a frequency-divider U and thence to the carrier wave modulator UH and transmitting-aerial S. At the receiver the aerial E feeds a detector UH and the output passes to a frequency-multiplier U giving the original signal in the receiving- device N.

Title: Manufacture of shaped articles from polyvinyl alcohols
IPC: C08J3/09
Filed: 1932-03-09
Abstract: The processes of the parent Specifications for the production of artificial threads, ribbons, tubes, and the like from aqueous solutions of polyvinyl alcohol, which products are particularly suited for surgical purposes, are modified by substituting the aqueous solvent by an organic solvent, e.g. ethylene glycol, butylene glycol, or glycerine, by adding barium sulphate or a bismuth compound to improve the visibility of the product under Röntgen-ray illumination, or by adding to the solution a substance such as gelatine, a gum, sugar, albumin, starch, or borax, which increases the capacity of the products for being resorbed.  In examples, (1) barium sulphate or a bismuth preparation is incorporated in a paste of polyvinyl alcohol, water, and alcohol used in the production of threads suitable as internal sutures; (2) threads for surgical purposes are produced from a solution of polyvinyl alcohol which contains gelatine, albumin, gum, starch, or sugar; (3) a solution of polyvinyl alcohol in glycerine is extruded at 100 DEG  C.

[Class 73.] A machine for labelling bottles or other cylindrical articles, of the kind in which the bottle &c. is rolled along a table past an adhesive applying device and a label pile by means of an endless belt, is provided with a single lateral wall forming a guide, and with a blotting device over which the bottle &c. is rolled after picking up the label from the pile ; electrically-operated devices are provided for controlling the raising of the pile, and for stopping the machine in the event of the failure of the supply of bottles &c. The bottles 19, Fig. 1, are transferred from a conveyer 1, by means of a spider 6, to the table 4 along which they are rolled by an endless band 2 having thickened side portions which engage the bottle so as to leave the central portion free for the label, the bottles being guided by a side wall 7. The bottle passes over an adhesive applying device consisting of a band 8 moistened from a trough 11, and then over the top of a label pile 12, the detached label being blotted by a blotter 13 in the form of an endless band. The label pile is raised by screw-gearing operated through a clutch which is controlled electrically, as shown in Fig. 4. At one side of the pile is a serrated member 14, while at the other is a pivoted member 15 one, inclined, end of which engages the edges of the labels, while the other end forms one of a pair of contacts 20 in circuit with a solenoid 211 controlling the clutch. If the label pile is raised too rapidly the lever 15 closes the contact thus temporarily throwing the clutch out. The table is fitted with contacts arranged so that unless the bottles are spaced normally a circuit is closed which effects stoppage of the machine.

Abstract: 1,218,663. Flexible waveguides. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 22 July, 1968 [20 July, 1967], No. 34932/68. Heading H1W. Flexible waveguides of internal non-circular cross-section, symmetrical about one or both orthogonal axes, are weaker in the region of these axes than elsewhere, whereby less deformation upon bending occurs. The internal shapes may be based upon the Ovals of Cassini and may include symmetrical ovals (Fig. 1), flattened ovals (Figs. 2, 3, not shown) and reentrant ovals (Fig. 4, not shown). The waveguides may be made from drawn, seamless aluminium tubing and the wall thickness may be thinner in the region of the axes than elsewhere. The same effect may be obtained by surrounding a tube 1 of constant wall thickness with a reinforcement 2 of dielectric material having a thickness which varies in the manner required. Alternatively, the uniform tube may be reinforced by longitudinal dielectric or metallic strips at cross-sectional positions remote from the axes. The waveguide may be designed to have equal flexibility about both axes.

Underwater breathing equipment for use primarily in exhausting air from the lungs during ascent from a great depth, as from a submarine, comprises a two-way valve 13 by means of which a mouthpiece 1 may communicate either with an air supply through a tube 12 or with a tube 10, leading through a light non- return valve 15 to the surrounding water. Normally the user exhales continuously during his ascent and the exhaled air passes through the valve 15 into the water, but if the ascent is interrupted for any reason it is possible for him to inhale the air contained in the tube 10 until his ascent is continued, since water cannot enter this tube. In other forms of the apparatus a flexible chamber is built into the tube 10 to provide a greater reserve of air. Specification 746,794 is referred to.

The piston C has a reduced upper piston C<1> which is engaged by a screwed plug d<2> located in the lower hollow portion of the gauge bar. This plug serves for adjusting the zero of the instrument. A projection d<4> is formed on the free end of the gauge bar to serve as a tyre-valve depressor when it is desired to release excessive pressure in a tyre.
