Abstract: 1,134,189. Pasteurizing eggs. BALLAS EGG PRODUCTS CORP. 3 Dec., 1965 [27 Sept., 1965], No. 51479/65. Heading A2D. Liquid egg products, such as egg white, are preserved by removing a major proportion of the trapped air in the products by vacuum treatment while the products are at a temperature below that at which they coagulate, and then pasteurizing them. Where the products are subjected to preheating prior to pasteurization by heat exchange with the pasteurized products, the vacuum treatment is preferably effected after this pretreatment. Suitable forms of apparatus are illustrated with flow diagrams.

In a first embodiment (Fig. 3) the tape recorder includes a power source 1, a motor 3, an amplifier 2, an on-off switch 4, an earphone socket 13, a remote control socket 13 and a microphone socket 6. An output amplifier 21 which feeds a loud-speaker has two input plugs 23, 24. Plug 23 has its centre terminal connected to its shield through a switch 25 which, when closed (and assuming switch 4 is closed) is connected to the positive terminal of power source 1. Plug 24 has its centre terminal connected to the output of amplifier 2 through socket 13 for transfer of audio-frequency signals while its shield provides, through socket 13, a connection from amplifier 21 to earth. Switch 25 acts as a remote control for the tape recorder and may, if desired, be omitted (Fig. 2, not shown). An electrical attachment device (Fig. 5) includes a condenser microphone 32 and an impedance matching F.E.T. 33. Into the remote control socket 5 of the tape recorder is inserted a plug 34, the centre terminal and shield of which are normally shorted together by a switch 42 which acts as a remote control for the tape recorder. Power supply for the F.E.T. 30 is provided by the positive terminal of the power source 1 through plug 34 and socket 5, an earth connection being provided through plug 35 and socket 6. Audio frequency output from the F.E.T. is through the centre terminal of plug 35. Preferably an R.C. network prevents oscillation of the condenser microphone circuit. The microphone 32 and F.E.T. 33 are in one case 31 and the switch 42 and R.C. network are in a second case 41 located along the cable between microphone 32 and plugs 34, 35, Fig. 6.

An F.M. tuner (Fig. 9) may alternatively form the electrical attachment device and draw its power supply through the remote control socket 5 of the tape recorder, the earth connection being provided through the tape recorder microphone socket 6. The tuner output is applied to the tape recorder amplifier 2 through the centre terminal of plug 58. An F.M. transmitter 52 may receive intelligence from a microphone 51 physically spaced from the tape recorder.

As shown the thermoplastics material is of polyethylene and forms a net having threads 1 and 2. The fibrous material is of glass fibre and is heated so that the narrow threads 2 are fused into the glass fibre. Threads 2 give the sheath mechanical stability and act as separators from the nearest components. The sheath is heated on a suitable mandrel which is itself heated by I.R.-irradiation or induction heating. With induction heating it is also possible to obtain, through suitable frequency selection, dielectric heating of the fibrous material, caused by inner molecular friction. The thermoplastics material may be extruded through a circular or rectangular nozzle or die so that a discontinuous layer of the desired appearance is obtained in the form of a net of the desired appearance in the form of a tube. The fibrous material is fed through the nozzle and thereby is placed inside the thermoplastics material.

Abstract: 1,126,001. Photo-electric coating thickness control. UNITED STATES STEEL CORP. Dec. 31, 1965 [Jan. 6, 1965], No. 55497/65. Heading G1A. [Also in Division H1] The density of a vapour in a vapour-coating machine is measured in order to control the coating thickness, by subjecting the vapour to a high energy beam, e. g. of electrons, in order to produce characteristic X-rays, a portion of which is detected and measured. The particular application is in the continuous coating,of strip material and is suitable for thickness control in the vacuum coating of steel strip with aluminium. In one arrangement, Fig. 1, an electron beam 2 from a gun 1 is bent in a semicircular arc by a magnetic field to heat and melt the coating material 3 in a crucible 4. The resulting vapour flows towards the strip 6 to be coated. The electron beam 2 comes into contact with atoms of the coating vapour producing characteristic X-rays 8. Some of these enter the collimator 9a of a detector 9, the output of which is amplified, and counted, allowing for scattered radiation. In another arrangement, Fig. 2 (not shown) separate means produce the coating vapour which flows through a housing (10), an electron beam being directed at right angles to the flow of the vapour. Characteristic X-radiation emitted in a direction mutually at right angles to the electron beam and vapour flow, is investigated by the collimatordetector system.

The polyurethane is preferably a random thermoplastic copolymer. In examples, (a) is a poly-(oxyethylene carbonate) glycol prepared from ethylene carbonate and ethylene glycol, (b) is 4,4<SP>1</SP>-methylene-bis- (cyclohexyl isocyanate) of stereoisomeric ratio 55% trans : 45% cio, methylene-bis-(4-phenyl isocyanate) or toluene diisocyanate and (c) is 1,4-butanediol.  Laminates may be made by the following techniques (1) air is evacuated from an assembly of glass and polyurethane plies, which is first heated to soften the polyurethane and seal the edges and then heated under pressure, e.g. in an autoclave, to seal the plies. Edge sealing may be dispensed with by using a vacuum bag. The polyurethane plies are formed from the polymerized material by extruding, pouring into trays, milling and/or calendering and are dried before incorporation into the laminate, (2) Two glass plies are spaced apart, e.g. by tape, and liguid polyurethane is poured into the space and cured. (3) Liquid polyurethane is sprayed on to a glass sheet and heat is applied. (4) A glass pressure plate is used to adhere polyurethane to a single glass sheet. When methods (1) and (2) are used to produce glass-polyurethane-glass laminates, one of the glass sheets may be treated with a release agent so that it can subsequently be removed. Adhesion promoters, e.g. alkoxy silanes, and adhesion inhibitors, e.g. alkyl acid phosphates, may be included in the polyure- 'thane reactants or may be applied to the sheets to be assembled. The glass may be chemically strengthened or tinted and may be of thickness 0À065-0À180 inch. The thickness of a polyurethane interlayer may be 5-120, preferably 15-45, mils. The Specification also describes the preparation of a laminate for testing purposes by bonding the polyurethane between two polyethylene films.
