Title: Method of accelerating the hardening of adhesives
IPC: C09J175/00
Filed: 1967-04-14
Abstract: A method of accelerating the hardening of anaerobic adhesives or sealing compounds based on a mixture of an acrylic or methacrylic ester, an organic peroxide and an amine, comprises pretreating surfaces, which are to be joined together with said adhesive or sealing compound, by depositing thereon a coating of an organic isocyanate.  The (meth)acrylic component may be a partial or full ester of, for example, ethylene, diethylene, triethylene, tetraethylene, propylene, butylene or neopentyl glycol or of trimethylol-propane, or it may be an ester of a monohydric alcohol such as cyclohexanol, tetrahydrofurfuryl alcohol or 1,3-dioxa - 2,2 - dimethyl - 4 - methylolcyclopentane. Suitable peroxides include cumene hydroperoxide, t-butyl hydroperoxide, diisopropyl benzene hydroperoxide, t-butyl perbenzoate and 2,2 - bis - (t - butylperoxy) - butane, and amines specified are triethylamine, tributylamine, N,N,N1,N1 - tetramethyl - 1,4 - butane - diamine, N,N - diethylcyclohexylamine, N,N - dimethylaniline, N,N - dimethyl - p - toluidine, N - methylpiperidine, N-methylmorpholine and 1,4-diaza - bicyclo - [2,2,2] - octane.  The isocyanate accelerator may be an aliphatic or aromatic mono- or poly-isocyanate, or a higher molecular weight product as obtained, for example, from aromatic uret dions. The isocyanate is generally applied to the surface to be treated as a solution in an inert organic solvent, e.g. a halogenated hydrocarbon. The method is suitable for bonding together materials such as zinc, iron, anodized aluminium, highly alloyed steels, cadmium, glass or plastics, e.g. polymethacrylates and polyvinyl chloride.  In some examples the ester monomer was stabilized with hydroquinone and, in one case, the monomer (2-hydroxyethyl methacrylate) is admixed with polymethyl methacrylate.

Title: Improvements in or relating to magnetically-recording high-frequency signals
IPC: H04N5/926
Filed: 1958-05-29
Abstract: 886,734. Magnetic recording; television. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 29, 1958 [May 29, 1957], No. 17174/58. Class 40 (2). [Also in Group XL (b)] In an arrangement for recording television signals on a magnetic carrier the signals are sampled at intervals equal to an odd multiple of half the line scanning frequency and quanticized into a plurality of discrete amplitude levels which are then recorded as saturated magnetic signals on a like number of parallel trucks on the carrier in a distribution determined by the particular amplitude levels. Fig. la shows, graphically, the principle of the arrangement when the television signal St is sampled by pulses P having a repeition frequency equal to one-half the line scanning frequency and quanticized in 10 discrete amplitude levels each of which is recorded with constant intensity on corresponding ones of the tracks 1 ... 10 on the magnetic record which moves in the direction f past the erasing and recording heads Tf, Tr, respectively, as shown in Fig. 1b The inverse process, i.e. that of reproducing the original television signal from such a recording is described in connection with Figs. 1c, 1d and Fig. 3 (not shown). For producing the signal samples a cathode-ray tube in which the beam is deflected over a number (10) of separate electrodes to produce signals controlling gating circuits for each discrete level may be employed (Fig. 2, not shown). Alternatively, a short-persistence cathode-ray tube co-operating with photoelectric cells, one for each gate circuit, may be employed. Reference is made to recording colour and stereoscopic signals and associated sound and synchronizing signals.

Abstract: 963,358. Automatic exchange systems. GENERAL ELECTRIC CO. Ltd. May 2, 1962 [May 11, 1961], No. 17230/61. Heading H4K. In an arrangement for identifying a calling line, a relay ND in the line circuit energizes in response to potential applied to the private wire at a junction relay set and marks wires 51 ... 60 in accordance with the digits of the line number, these markings being effective in succession by a control over wires 62 ... 64. As shown, the markings are transferred in a 2-out-of-5 code to a tape perforator which is associated with the junction relay set and records also the called number and metering information. Each digit repeated over the junction steps switch 1C which at the end of the digit connects up the appropriate magnets of the tape perforator. After the reply of the called party, relay D then being operated, switch 1C is stepped by metering impulses received by relay M. Sequence switch PD advances at this time, and an allotter associates the identifying circuit with the junction relay set, whereupon relay 1D operates and applies potential to the private wire to energize relay ND in the subscriber's line circuit. In this and subsequent positions of PD, the markings applied by relay ND to wires 51.. 60, which indicate the digits of the calling number, are effective through a coder to operate the relevant magnets of the tape perforator. At each tenth metering impulse switch 1C transfers a record to the tape perforator, and a further record of impulses less than ten is made at the end of the call. Magnetic drum registers may be employed in place of a tape perforator, and use of a 2-out-of-5 code is not essential. The marking wires may control lamps to indicate the calling number visually. According to the Provisional Specification a separate group of marking wires may be provided for each digit, and the tape perforator may be common to the junction relay sets.

Title: Improvements in devices for measuring the thickness of sheet metal and the like
IPC: G01B7/06
Filed: 1934-06-11
Abstract: 429,227. Linear-dimension gauges. KARAJAN, W., 12, Molkerbastei, and KHUNER, U., 71, Neubaugasse, both in Vienna. June 11, 1934, No. 17241. [Class 106 (ii)] [See also Group XXXVI] The thickness of sheet metal and metal foil is measured without touching the material by passing the foil between coils, the " transmitter " group of which is traversed by alternating current while the voltages induced in the " receiver " group provide a standard for indicating thickness. The frequency of the electromagnetic waves employed is determined according to the thickness and conductivity coefficient of the material to be measured, and must be the lower the thicker and better conducting the material is. Fig. 2 shows a differential method, the coil 1 inducing voltages in coils 2, 3 so that after rectification by valves 6, 7 direct current flows in the equal resistances 10, 11. Tuning condensers 4, 5 and bridging condensers 8, 9 are provided. By adjusting a resistance 13 the instrument 12 can be made to read " zero " for a certain thickness of foil 14. The various settings of the resistance may be calibrated for various thicknesses. This arrangement is independent of fluctuations in the voltage supply. In another form, the coil 1 has substituted for it two coils in parallel, the resistance 13 being dispensed with. The adjustment of the current strength in this case is obtained by alteration of the reaction of one of the coils in parallel on the coil 3. To do this the coils 19, 20 are mounted as shown in Fig. 5, a screen 22 of volute configuration being moved to a greater or less extent between the coils by rotating the spindle 21. The coil 2 and second parallel coil are fixed in a holder and may be screened off by hoods from outside fields. These coils may be each replaced by two coils in parallel or series separated by metal partitions to prevent undesirable reaction. The appratus may be compensated for temperature effects, for total induction variations due to variations in the position of the sheet of foil, and for valve defects.

Storing under pressure.-Porous fillings for use in the storage of gases under pressure consist (a) of pieces of chacoal of the largest size that can be introduced into the container and of such a shape that the free space between the pieces is reduced to a, minimum, and (b) of a pulverulent material, such as pulverized charcoal, which can assume, by simple settling, a sufficient density to avoid the propagation of explosions. In practice, there are used pieces of charcoal the length of which is not greater than the diameter, and, in filling the containers, the pieces and the pulverulent material are introduced separately at the same time. The filling is then completed by placing a filtering material in the upper portion of the container, and the pulverulent material is made to settle by dropping the container on to a fixed mass without allowing it to rebound. This may be effected by suitably arranging an electromagnet on the fixed mass.

Abstract: 152,758. Murray, J. Erskine-. July 18, 1919. Drawings to Specification. Directive wireless signalling; bearings, determining wirelessly.-A wireless navigational system comprises a transmitting-station with two directive aerials rotating in azimuth and radiating waves of slightly different frequency, and a receiving station with a heterodyne source of a frequency differing slightly from both transmitted waves, the direction of the transmitter being ascertained by listening for a pure single note and noting the time since a ' cardinal point ' signal was received. When both waves are being received, the sound heard is a chord or a pulsating note, but when the energy received from one of the rotary aerials is zero or a minimum, the heterodyne note becomes pure. The two transmitting aerials are arranged so that one radiates maximum energy in a given direction when the other radiates minimum energy. If no local highfrequency source is used at the receiver, a beat note due to interference between the two radiated waves will be heard except when the energy received from either aerial is zero or a minimum. In a modification, only one wave is transmitted, and two oscillations of differing frequency are generated at the receiver. Instead of rotating the aerials at the transmitter, apparatus may be provided for varying the direction of maximum radiation from fixed aerials.
