Title: Improvements in and relating to units for heating liquid circulating in a heating system
IPC: F24H1/28
Filed: 1962-04-30
Abstract: 930,416. Hot-water boilers. WEBASTOWERK G.m.b.H. April 30, 1962 [June 9, 1961], No. 16512/62. Class 64 (1). In a unit for heating liquid circulating in a heating system, for example, a vehicle heating system, comprising a horizontally-disposed cylindrical fuel combustion chamber surrounded by an annular jacket through which the liquid to be heated flows and having inlet and outlet connection for the liquid situated above a horizontal plane containing the longitudinal axis of the combustion chamber; a baffle is provided in that portion of the annular jacket which is situated above the horizontal plane, between the inlet and the outlet, the baffle dividing the annular jacket in its longitudinal extent into two parts, but in the highest region of the jacket not absolutely separating the two parts from one another. In the form shown, the unit has a combustion chamber 3 with a pre-combustion section 1 and after combustion section 2, an annular return gasflow passage 14 leading to an outlet 15 and being surrounded by a water jacket 4. The after-combustion section 2 has a water jacket 11 connected to the water jacket 4 by two vertical bridge-like passages 12, 13 passing through the annular passage 14. The water jacket 4 is effectively divided into two by a baffle 7 located between an inlet 8 and an outlet 9 and extending for 270 degrees around said jacket. A small circumferential gap 16 exists between the baffle and the outside wall of the water jacket 4. Rapid heating of the water in the water jacket 11 causes a strong thermo-siphon flow to occur up through the bridge-like passages 12, 13 to the outlet 9, this helping to induce the flow of liquid from the inlet 8 down through the jacket 4 to the gap between the ends of the baffle and then up towards the outlet. The thermo-siphon flow draws any air or steam bubbles which may collect around the inlet side of the baffle through the gap 16 to the outlet. A circulating pump 17 disposed below the inlet 8 is driven by an electric motor which also drives a fuel atomizer 19 and combustion-air blower 18, this position allowing air bubbles to rise from the pump to the inlet 8 of the heating device and thence to pass to the outlet as described. Specification 930,417 is referred to.

Title: Improvements in or relating to amplitude-control circuits for electronic amplifiers
IPC: H03G11/00
Filed: 1946-05-31
Abstract: 619,523. Radio receiving circuits. PHILIPS LAMPS, Ltd. May 31, 1946. No. 16537. Convention date, June 1, 1945. [Class 40 (v)] A circuit for producing a delayed control voltage for automatic volume compression, comprises a valve 1 (Fig. 1) having at least one control grid to which the delay potential is applied from battery 7, the signal being applied to the grid and anode of this valve in the same phase, in this case through condenser resistance network 3, 4 and 5, 6 respectively. The control voltage is developed across a condenser 10 in the anode circuit. By this arrangement a more sensitive control is obtained than with a diode. In one alternative arrangement (Fig. 3, not shown), the signals for the grid and anode are obtained from the cathode and anode respectively of an amplifier valve, the delay voltage being obtained from the cathode resistor of the amplifier. In the volume compressor circuit of Fig. 4, the grid of rectifier valve 7 which produces the control voltage is fed from the input circuit of the one valve 5 of a pushpull amplifier 5, 6 and the anode of the rectifier is fed from the anode of the opposite valve 6 of the amplifier. The control voltage developed across condenser c2 is applied to grid g1 of preamplifier stage 4. The negative feed-back connection from coil 15 on the output transformer to the input circuit is stated to increase the control sensitivity by reducing 3rd harmonic distortion.

Title: Improvements in or relating to retort construction
IPC: C10B1/04
Filed: 1931-06-06
Abstract: 386,335. Gas retorts ; charging and discharging. INTERNATIONAL BITUMENOIL CORPORATION, 75, West Street, New York, U.S.A.-(Assignees of Vandegrift, J. N.; 75, West Street, New York, U.S.A.) June 6, 1931, No. 16593. Convention date, March 5. [Classes 51 (ii) and 55 (i).] Vertical retorts, each comprising an inner lining of sheet steel encased in firebrick, are mounted in a heating chamber by welding together the upper and funnel-shaped parts of the retorts to form a gastight partition from which the retorts are suspended, the lower ends of the retorts being also welded to a bottom plate. Each retort is formed of a welded steel tube 13 the upper part of which terminates in a square funnel 15, the edges of which are welded to the adjacent funnels forming a mounting supported by a rectangular trough 36 and bars 16. The lower ends of the retorts are welded to a bottom plate 17. Firebrick sections 18 enclose the tubes 13, and form flues in which are gas burners 33 connected with air and gas pipes 25, 26. Shields 60 of firebrick form a roof to the flues, and the combustion products are withdrawn through passages 22, and used to preheat the coal in hoppers 43 mounted on rails 46, and discharged by operation of a slide 47, when the cover 38 of the retorts is raised by hydraulic means 41. To prevent expansion, and thus obtain a compressed coke, discs 39 attached by rods 40 to the cover 38 rest on the surface of the charge, sufficient clearance being provided to allow of the distillates escaping from the charge to the space below the cover. The coke is discharged by lowering a bottom plate 49 by hydraulic means 52, until the wheels 54 of its supporting girders 51 rest on rails 55 so that it may be moved clear of the retorts. The temperature of the retort tubes is maintained at about 1400‹ F. when the coal is charged. Specification 386,343 is referred to.

Title: Improvements in or relating to adhesive-applying apparatus
IPC: B65C9/22
Filed: 1943-10-13
Abstract: 579,175. Adhesive applying apparatus. STEVENS, A. H. (Stokes & Smith Co.). Oct. 13, 1943, No. 16805. [Class 95] Apparatus for applying adhesive to sheets comprises a sheet-engaging roll and a scraper extending lengthwise of the roll to define a valley to which adhesive is delivered, and trough structure engaging the respective ends of the roll and of the scraper on opposite sides of the valley and coextensive therewith for conducting adhesive from the valley. In Figs. 1 and 4 the roll 1 co-operates with an intermittently operated doctor roll 4. to define a valley V into which adhesive is discharged from pipe 5. The surface of roll 1 in passing through the adhesive in valley V received a thin coating transferred to wrappers W fed to roll 1 by rolls 2, 3 and deflected therefrom by knives 32 on to the conveyer 33. The excess of adhesive supplied to valley V is collected by troughs 6 and then flow downwardly through chutes 9, 9 of collector member 9a. Some of the adhesive escapes from openings 10 in chutes 9, 9 for discharge from troughs 12a spaced lengthwise of a second valley V1; the remainder of the adhesive reaches the common spout 12; thus the adhesive is discharged from member 9a into the valley V1 defined by roll 13 and scraper 14. When the frame 43 is swung away from position of Fig. 4 to the position of Fig. 1, for cleaning or inspection, the adhesive discharges from spout 12 directly into the detachable tray 11 instead of into valley V1. The roll 13 transfers adhesive from valley V1 to roll 15 which applies adhesive to tab face destined to engage sheets fed by rolls 2 and 3 into engagement with roll 1. The tabs are cut from strips by knives 44 associated with tabbing heads 45 adjustably supported by the frame 43. Referring to Figs. 1 and 4, while the knives 44 are in their upper position each of the tab strips is fed by a pair or rolls 46, 46 to extend beyond the path of the associated knife corresponding with the desired length of a tab; the leading end of the strip is directed by guide elements 49 into engagement with the the tub-coating roll 15. On downward movement of the knives to sever the tab strips, a tab is cut from the leading end of each strip and the pair of tabs so formed are carried by roll 15 toward roll 1 on to which they are guided by stripper blades 47. A water jacketed thermostatically controlled container 16 acts as a reservoir for the adhesive which is agitated by paddle 20, and connected via pump 51 to distributing head 5. A two-way valve 53 serves to connect the pump 51 with a source of cleaning liquid instead of with the reservoir 16, as so shows the machine to be cleaned.
