The intermediate section 86 is driven by a pinion 122 which engages a rack 132. The load-supporting section 84 is driven by sprockets 156, 186, Fig. 8, which engage a chain 184 fixed'to the section 84 and are themselves driven by coaxial sprockets 150, 185 which are rotated by fixed chains 154 as the intermediate section is driven. The shuttle may be extended either to the right or to the left and starting and stopping are controlled by electrical limit switches. The shuttle is gradually arrested by a shock-absorber assembly 190, Fig. 10, comprising shock-absorbers 192, 194. The latter are pivoted to each other and to a pivoted operating level 210. The lever 210 is engaged by a central stop 224 with two camfaces 222, 240 which are operative in the retracted position of the shuttle, and two stop members 242, 236 which engage the lever 210 at the extreme extended positions.

Title: Improvements in or relating to synchrodyne receivers
IPC: H04N5/50
Filed: 1966-12-02
Abstract: 1,146,865. Automatic frequency control systems; modulators. INTERNATIONAL STANDARD ELECTRIC CORP. 2 Dec., 1966 [3 Dec., 1965], No. 54107/66. Addition to 1,131,245. Headings H3A and H3R. A synchrodyne receiver wherein the input is modulated in unit 2, Fig. 2, by signals from an auxiliary oscillator 9, the auxiliary signal being recovered from the output of the L.F. or video amplifier 5 and passed to a phase detector 10 which controls the frequency of the local oscillator 4, is characterized in that the modulator 2 modulates the input in both amplitude and phase. This modulation may be such as to produce a single sideband, but for receiving vestigial sideband modulated signals it may be preferable to arrange the amplitude and phase modulation so that double sideband quadrature modulation results. As illustrated the auxiliary signal may also be used to control the gain of amplifier 5; if necessary the auxiliary modulation may be applied as inverse amplitude modulation of the final signal to suppress the amplitude modulation component introduced in modulator 2. For reception of television signals the auxiliary modulation may be applied only during the line fly-back periods. A high quality receiver may use two mixers and two amplifiers with a common local oscillator, one set operating on the received signal and the other on the received signal modulated by the auxiliary signal. Modulator, Fig. 6.-The carrier from source 15 is modulated in amplitude by the potential divider formed by the internal resistance 16 of source 15 in series with a diode 17, the resistance of which is varied by modulation applied through capacitor 21. The amplitude modulated carrier is then phase modulated by a variable capacity diode 23 controlled by modulation applied through capacitor 26. If the two modulations are in phase quadrature, the output is a single sideband (Fig. 5f, not shown); if they are in phase or in phase-opposition the output is a double sideband quadrature modulation (Figs. 5d and 5h).

Abstract: 1453300 Combustion furnace H KUNSTLER 29 Nov 1973 [30 Nov 1972] 55444/73 Heading F4B The walls of a combustion furnace for refuse incineration are air-cooled in the region of a grate 64 so that beads of slag do not form on the walls. As shown, a combustion chamber has outer and inner spaced metal walls 4, 5 and a metal shield 6 spaced from the inner wall. Cooling air is supplied through a duct 4a and passes through a hollow space 10 between the walls 4, 5, thence through openings 7 into a hollow space 9 between the wall 5 and the shield 6, and thence through openings 8 into a fire chamber 2 of the furnace. This air aids combustion of the refuse. Some of the air may be removed through an outlet 32. Instead of supplying air at 4a it may be supplied at 34. The shield 6 comprises mutually spaced individual metal plates 16. The spaces between the plates 16 comprise the openings 8. These openings 8 are offset with respect to the openings 7. Ribs 5a on the wall 5 divide the hollow space 10 into ducts. Fig. 4 (not shown) illustrates a furnace with similar air cooled walls having metal shield plates 16 on two sides of a step grate (64<SP>1</SP>). The steps (66, 68) have hollow upright metal walls (30) supplied with air through passageways (31). The upright walls (30) are perforated and provided with shields (6<SP>1</SP>a) having openings which are offset relative to those in the walls (30). Details of a shield (6) comprising plates (16) are illustrated in Figs. 5 to 7 (not shown). The plates (16) are hooked at (20) into openings (17) in an inner wall (5). Spacing of the plates (16) from the inner wall (5) and from each other is ensured by marginal projections (21a, 21b).

A well bore , 10 penetrating a plurality of vertically spaced, hydrocarbon - bearing productive zone A, B, C is completed by installing tubing strings 18, 20 and isolating the zones, e.g. by packers 22 in the cased part and by cement 14a in the inclined part. Pipe members 24 are inserted in string 18 adjacent each zone, each member having an inlet chamber 28 connecting via an adjustable choke with the inlet of a flow meter retrievably mounted in member 24 such that fluid from another zone cannot enter therein. Gas from the zone leaves the top of the flowmeter and liquids from the bottom. Fluids from other zones flow around bypass 49. Thus gas rises to the top of string 18 and liquids pass to a U-bend (or alternatively a sump) and are pumped to the surface via string 20. After installation of the strings and prior to insertion of the flowmeters, a perforating device is lowered into each member 24 to make perforations 16, member 24 being subsequently sleered.
