Abstract: 1,114,057. Air and water heating apparatus. VONO Ltd. 26 July, 1966, No. 33564/66. Headings F4A and F4S. The outer insulated casing 10, of a furnace for heating air and water, encloses a cylindrical member consisting of an upper tube 32, which is sealably connected to an aperture 15 formed in the casing cover 14, and a lower tube 34, of smaller diameter, which is joined to the tube 32 by means of a plate 35. A water pipe coil 55 surrounds the upper tube and a gas or oil burner 40 having a plurality of jets 41, is located around the lower portion of the lower tube. Identical baffle-members 20 and 30 are disposed above and below the coil, these having a circular aperture 24 of diameter slightly greater than the upper tube 32. At the top of tube 32 and within the lower end of tube 34 are disposed two semicircular closure plates 51 and 46 respectively, pivoted about their diameter and interconnected by rods 49 so that if one of the plates 51 is raised, the corresponding plate 46 rises. In use, with the burners lit, air for combustion being supplied by apertures 45 and fuel controlled by member 43, hot combustion gases rise within the space formed between the tubes 32, 34 and the outer casing so heating the coils 55, with the progress of hot gases being impeded by baffles 30 and 20, and waste combustion products being removed through flue outlet 56 and flue 58. If it is desired to simultaneously heat air, then the plates 51 and 46 are raised and an electric fan 39 actuated so causing a flow of air through the tube, during which passage, it is heated by contact with the hot inner surface of the tubes 32 and 34. If no hot air is required then the plates 51 and 46 are closed thus trapping air within the tube, which air, after initial heating removes no further heat from the combustion gases so providing more heat for the hot water coils 55.

Title: Devices for integrating oscillatory displacements
IPC: G01B5/28
Filed: 1947-12-23
Abstract: 658,513. Counting-apparatus; gauging surface-roughness; indicating vibrations. LINCOLN PARK INDUSTRIES, Inc. Dec. 23, 1947, No. 33903. Convention date, Feb. 8, 1946. [Classes 106 (i), 106 (ii) and 106 (iv)] [Also in Group XXIV] A mechanical displacement integrating device comprises a rotary disc-like indicator whose axial end surface is frictionally engaged by a control member at an end of a pivoted oscillatable member whose other end is driven in dependence on a displacement corresponding to a characteristic to be measured. Fig. 2 illustrates the principle of the invention. A beam 31 oscillating in the direction of arrows 32 carries a cross-bar 30 with resilient feelers 28, 29 engaging an indicating disc 26 at an acute angle so as to apply a one-way friction drive thereto, the total amount of rotation of the disc corresponding to the total displacement of the beam. The feelers may be metal, fibre, glass or plastic filaments. In a surface roughness indicating device, Fig. 10, the beam 70, pivoted at 72, has feelers 75 at one end and a stylus 73 at the other pressed into engagement with the surface to be gauged by a spring 77. The device is slid over the surface on gliders 118, 120 and any irregularities will cause the stylus and beam to oscillate and effect a corresponding rotation of an indicating disc 78, so that for a given surface length a measure of its roughness is given by a stationary pointer 93 against a graduated scale 81 on the disc. The disc has a roughened spherical surface to ensure constant pressure on the feelers, and is mounted in a carriage 80 suspended in a frame 71 by plate springs 98, 104. A zeroizing lever 95 rotates a shaft 96 having a cam 97 which engages the spring 98 to urge the carriage to the right, thus freeing the disc 78 from the feelers so that it can be reset by a spring 91. The normal position of the carriage 80 can be adjusted by a screw 110. The device may be adapted for gauging cylindrical surfaces or surfaces inside small openings. In a modification, the indicating disc is constantly rotated, e.g. by clockwork, and movement of the feelers varies the frictional retarding torque so that the total rotation of the disc is a measure of the deviations of the surface from a datum plane. Indicating vibrations. The invention may be applied also to a seismic vibration indicator, the beam carrying a large mass instead of a stylus, and a timing device being provided. Alternatively, the beam may be directly connected to a vibrating body.

Abstract: 1421974 Automatic timing control COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 18 July 1973 [19 July 1972 14 Sept 1972] 34318/73 Heading H3A An arrangement for locking the local carrier of an a.m. digital data demodulator comprises: first means responsive to demodulated bipolar signals for generating a first and second signal representative of the time during which the bipolar signal departs from first and second peak-limiting levels of opposite polarities; means for integrating the demodulated signal; means responsive to the first and second signals to control the integration; and means to apply the integrator output to control the phase of the local carrier signal. Demodulator X, Fig. 1, receives a signal S1 amplitude modulated with bipolar data at one input, and the carrier signal, divided via bandpass filter F1 and limiter E3 at the other. In order to phase adjust the carrier, a variable delay device Y controlled by error signal T, is included. The filtered demodulator output S2 is fed to positive and negative limiters El, E2 which produce twolevel outputs el, e2 whose levels depend on which side of the limiting levels S2 lies. The signals S2, el, e2 are fed to a logic circuit L which produces the error signal T. In an alternative embodiment, Fig. 4 (not shown), the local carrier is derived from a V.C.O. (J) and divider (D), the oscillator frequency being adjusted by the error signal T. Logic circuit, Figs. 2, 3.-The signal e1, Fig. 3c, is applied to a circuit comprising inverters N1, N2, resistor R 0  and capacitor C 0  to produce a train of short pulses # 4 , Fig. 3g, whenever the signal S1 falls below the negative threshold El. Signal e2 is applied to a train of monostables M1, M2, M3 to produce trains of pulses # 1 , Fig. 3d, # 2 , Fig. 3e and # 3 , Fig. 3f. During period # 1 , FET W2 is turned on to discharge capacitor Cl. During period # 2 , FET W2 turns on to charge capacitor C1 to the level of signal S2. If the timing of pulse # 4  is such that it falls within period # 3 , it passes through gate N6 to turn on FET W3 and transfer the charge on capacitor C1 to capacitor C2. The voltage across C2 is then fed to integrator A7 via high impedance stage W4, to produce the error signal T which varies the impedance of FET W5 in the delay circuit Y.
