IPC: A43B23/02
Filed: 1963-11-27
Abstract: In forming a backseam for a shoe upper two quarters are assembled on two surfaces of a forming member which meet at a curved edge corresponding to the shape of the backseam, and the edges of the quarters are bonded together, the edges of the quarters being arranged to abut at the edge of the forming member, or the edge of the first quarter being bent around the edge of the forming member on to the second surface and overlapped by the edge of the second quarter.  Leather quarters are bonded by adhesive, but weldable plastic coated fabric quarters are bonded by welding.  The forming member may have parallel surfaces with a rounded edge (Figs. 4, 5, Figs. not shown), one surface chamfered (Figs. 2, 3), or both surfaces chamfered (Figs. 6-9).  Alternatively the member bay comprise curved, preferably cylindrical, surfaces 124, 126 (fig. 10) meeting at a curved edge 128 at approximately 90 degrees.  The seam shown in Fig. 3 is formed by folding the first leather quarter 8 around the edge of member 12, sticking it thereto by pressure-sensitive adhesive, scouring the edge portion 22 until it is level with the second surface 20, coating with adhesive the skived face 6 of the second quarter and arranging it over surface 22, and bonding the parts together by heat and slight pressure using a dielectric heating apparatus.  In Figs. 4 and 5 the quarters are of cloth coated with polyvinyl chloride and are arranged with the cloth innermost.  The coating 46 of quarter 40 is skived at 52 and overlapped by the edge of quarter 32.  Metal template 48 with the quarters is lightly pressed between bed 58 and block 60 of silicone rubber and a high frequency electric field established by electrode 64.  In Figs. 6-9 quarters comprising layers of leather 76, 84, polystyrene impregnated fabric 78, 86, to form a counter stiffener, and lining leather 80, 88 are skived at 83, 96, and 112, the latter surface is coated with adhesive and covered by the skived surface 98 of layer 84 and the parts joined by high frequency heating.  The seams shown in Figs. 11-18 are formed on former 122 (Fig. 10). The quarters comprise fabric 130, 132 coated with polyvinyl chloride (Figs. 11, 13, 14), polystyrene impregnated fabric (Fig. 12), leather (Figs. 15, 16), or layers of leather 191, heat mouldable stiffener 192, and lining 193 (Figs. 17, 18).  The seams are formed by skiving one surface of the first quarter (Fig. 11) or on the surface of both quarters (Figs. 15, 16, 18), by skiving two surfaces of the first quarter which engage between two reentrant skived faces of the second quarter (Fig. 17), or by butting the quarters (Figs. 13, 14).  The adhesive may be heat or solvent activated.  A heel stiffening blank 140, 160 may be incorporated in the seam (Figs. 12, 14).

Filed: 1972-10-12
Abstract: 1372955 Electro-physical measurement GENERAL ELECTRIC CO 12 Oct 1972 [26 Oct 1971] 47214/72 Heading Gl The invention relates particularly to detecting the source of oil pollution. To identify a liquid it is "tagged" at source with sub-micron particles having at least one specific Curie point. The particles may be selected from ferrites, pervoskites, chromites and magnetoplumbites and have a concentration of between one and ten parts per million. When a sample of (polluting) liquid is found subsequently particles may be collected from it by a magnet (after dilution with a solvent if necessary to reduce viscosity). The Curie point of the sample is determined by placing it in a container 11 surrounded by a magnetizing coil 17 and mounted in an electric furnace 12. The susceptibility is determined by a pick-up coil and plotted against the temperature as detected by a thermocouple 15. As illustrated three types of particle have been used to tag the sample in Fig.2, giving rise to three peaks.

Title: Audio monitor
IPC: H04S7/00
Filed: 1975-11-20
Abstract: 1518299 Monitoring stereophonic sound J BENTLEY 17 Nov 1976 [20 Nov 1975] 47884/75 Heading H4J Correct balance of a stereophonic or quadraphonic sound system is tested by generating sounds in loudspeakers corresponding to particular tones and levels and monitoring the sounds using a microphone arrangement. An indicator shows the relation between the sound levels received from respective loudspeakers. The system amplifiers and loudspeakers are then adjusted to balance in accordance with the indicator. A monitor is mounted in a head-like housing 1 (Fig. 1). Two directional microphones 2, 3 have a response pattern corresponding in directivity to two human ears. A cassette deck 4 generates predetermined tones in loudspeakers 6, 7. Microphones 2, 3 feed respective battery powered I.C. amplifiers 8, 9 and meters 10,11. The speaker balance is then adjusted by a balance control 12. A common meter 15 may give a difference output. In an alternative arrangement (Fig. 2, not shown) two sound channels (16, 17) feed a single microphone (18). The microphone output is split into two channels (19, 20) having respective meters (21, 22). Switches (23, 24) are operated by a switch control 25 at 10 Hz in synchronism with a tone applied to loudspeakers 6, 7 in turn. Thus one meter (21) records the output from loudspeaker 6 and the other meter (22) records the output from loudspeaker 7. Alternatively there may be two microphones and isolated electrical channels. A difference meter 15 may be provided. Alternatively the monitor may have a single channel. For example, a single microphone 18 (Fig. 3) feeds on amplifier 26 the output of which is capacitively coupled to an envelope detector 28 whose output is a series of adjacent pulses which alternately have the amplitude level of the sound received by the microphone 18 from loupeaker 6 and loudspeaker 7. The indicator 33 (see Fig. 4, not shown) includes a light beam which displays a band of light, representing the difference between the two amplitude levels. Alternatively the output of the envelope detector is applied to a coupling capacitor (37) Fig. 5 (not shown) and to a further rectifier (38). Its output is a unidirectional square wave and is applied to a coupling capacitor (37) Fig. 5 (not shown) and to a further rectifier (38). The output is a unidirectional square wave and is applied to a damped moving coil meter (39). Its output is proportional to the difference between the amplitude levels received from the loudspeaker. The amplifier 26 may have A.L.C. The indicator may comprise lamps, L.E.Ds, L.C.Ds or a pair of headphones receiving the outputs of the two channels out of phase. When the amplitudes of the signals in the two channels are equal there will be total cancellation and no sound will be heard from the headphones.
