Title: Draught excluder for windows, doors, and the like
IPC: E06B7/232
Filed: 1947-02-05
Abstract: 625,755. Draught excluders. SABLATNIG, A. Feb. 5, 1947, No. 3396 Convention date, Oct. 15, 1945. [Class 20 (iii)  In a draught excluder in which the draught tends to press a flexible lamella into sealing position, this lamella is carried by a single piece of an elastic material which maintains it in operative position. A paper, metal foil or plastic foil lamella D may be glued internally, or as in Fig. 2 externally, to a V-shaped cardboard, sheet metal or stiff plastic sheet carrying strip T secured to the part K 1  and whose elasticity assists in pressing the lamella against the part K 2 ; carrying strip material may also be reduced in thickness along one side to provide an integral lamella. Fig. 4 shows a double folded carrying strip whose side T 3  serves to form an elastic support for the free limb of the V-shaped lamella D and for its own free side T 2 ; the draught excluder is secured by an adhesive. The Specification as open to inspection under Sect. 91 comprises also V-shaped metal clips (Fig. 6, Cancelled) to hold the draught excluder in position until the adhesive has set; these clips have two prongs 1, 3 which enter the door &c. frame, and a prong 2 which is pressed through the strips and is bent down to clamp them to the part B 1 . The invention may be so applied to both parts of double windows, doors, &c., that air tending to flow into the intervening space from either side presses the lamellae into sealing position. An arrangement is also described differing from Fig. 4 in that the side T 3  of the carrying strip forms a V within the V of the lamella, its outer edge and that of the side T 2  being doubled back against the lamella. This subject-matter does not appear in the Specification as accepted.

Patent GB-1463551-A (GB)
Title: Apparatus and process for producing the time average of the product of two arbitrary electric signals
IPC: G06G7/186
Filed: 1974-01-25
Abstract: 1463551 Generating time-averages PRINCETON APPLIED RESEARCH CORP 25 Jan 1974 [26 Jan 1973] 03513/74 Heading G4G A method of providing the time average of the product of two arbitrary signals A, B comprises periodically reversing the polarity of one signal B, multiplying the reversed signal by the other signal A, filtering the product to attenuate D.C. components, and synchronously rectifying the filter output to provide a D.C. signal corresponding to the average. Due to circuit imperfections &c., the output from multiplier M1 contain D.C. components and is subject to low frequency drift. A square wave of frequency fi is used to reverse the polarity of signal B in multiplier M2, e.g. a phase-reversal switch, the A.C. output from multiplier M1 has a peak-topeak amplitude proportional to the product (A x B), which is independent of D.C. components. A "rotating capacitor filter" removes the D.C. components leaving the square wave centred about zero. The square-wave is the A.C. amplified, further filtered to remove D.C. and synchronously rectified. The rotating capacitor filter has a capacitor C whose terminals are reversed by a motor, solid state switching, or mechanically in synchronism with the phase reversing signal to M2. When one of the arbitrary signals is itself a square wave, e.g. if the multiplier forms part of phase-sensitive detector, vector voltmeter, phase-lock amplifier, the other signal may be phase reversed by either this square-wave or the generator square-wave first (Figs. 3-4, not shown).

Title: Improvements in or relating to the construction of high pressure steam or other vapour generators and superheaters
IPC: F22B3/04
Filed: 1923-02-07
Abstract: 215,117. Burden, A. G., and Wallis, R. P. Feb. 7, 1923. Coiled tube superheaters; dampers for controlling superheaters.-Apparatus suitable for generating steam at or above the critical pressure and temperature of water, and for superheating the steam at a lower constant temperature consists of a group of concentric coiled generating tubes connected in parallel, and a similar group of superheating tubes, the generating tubes being in communication with the superheating tubes through a reducing valve. Water or other liquid supplied under pressure to the inlet header S, Fig. 1, passes upwardly through the coiled generating tubes K arranged on an annular flue around a combustion chamber G, and is collected in a header P, from which it flows into the superheating coils N through a reducing valve R which maintains a constant pressure in the generating coils and permits a continuous flow of the fluid to the superheater. Simultaneously operated dampers U<1>, U<2> control the passage of furnace gases through the superheater. The dampers are arranged in pairs on a number of vertical spindles, corresponding dampers above and below the superheater being placed at right angles to one another. In a modification, Fig. 6, the coils are arranged horizontally and the gases pass across the generating coils. The passage of the furnace gases through the superheater is controlled by a circular damper b made in three parts, each part having a spindle c operated by a lever.

Title: Improvements in and relating to the manufacture of bags
IPC: B31B23/00
Filed: 1956-08-06
Abstract: 837,421. Making bags. ARMELIN, E. R., and PLASKETT, A. F. G. Nov. 6, 1957 [Aug. 6, 1956], No. 3692/56. Class 94(2). [Also in Groups VIII and XXVIII] A process for the manufacture of a bag from a blank of flexible, heatsealing material, e.g. polyethylene or regenerated cellulose coated on both surfaces with nitrocellulose, comprises applying a transverse strip of anti-adhesive material to the blank, then forming the blank into a flat tube, folding back one end portion of the tube on to the body portion of the tube and adhesively uniting, by the application of heat and pressure, the folded end portion to the opposed outer surface of the body portion to form a transverse seam which closes the end of the tube, the anti-adhesive material being applied to the blank in such a manner that it is subsequently located between the opposed inner surfaced of the body portion of the tube in the region at which heat and pressure are applied, so that the said inner surfaces are not stuck together. A web 3 of heat sealing material is printed on its upper side (as shown) with transverse strips of printers' ink each of which extends from one side of the web to a line close to and parallel to the other side. The web is then fed under forming rollers 16 carried on a spindle 17 journalled in a bracket 18, and a forming plate 19 also mounted on the bracket 18, the combined length of the rollers 16 and the width of the plate 19 each being less than half the width of the web. The side portions of the web are folded over the plate 19 by forming fingers 20, 21 so that the edges overlap, the edge which is free of printers' ink being uppermost. The web is then fed under a roller 22 heated by a heater 24 and the overlapping edges of the web are pressed together between the roller and the plate 19 so that they stick together and the web is formed into a flat tube. The tube is cut into lengths by a knife carried by a roller 30, the cuts being made at a distance behind the leading edges of the inked strips which is equal to twice the width of the portion of the tubular blanks which is subsequently to be folded back. The blanks are then fed to a machine, which may be of the type described in Specification 837,420 where their rear ends are folded over and heat and pressure are applied to the portion so folded over the area of the inked strip only. The web 3 may be printed in such a way that the inner surface of the tubular blank is inked on one side of the tube only.

Title: Improvements in and relating to processes for working up acid sludge and the like
IPC: C10B55/00
Filed: 1933-02-13
Abstract: Acid sludge or like residue from the refining of oils is passed, with exclusion of air, through a red-hot retort in which it is heated mainly by radiation from the walls of the retort. Hydrocarbon vapours, gas, and a little carbonaceous residue are obtained.  The retort may be a vertical iron tube heated to 750 DEG  C., and may be provided with insertions to increase the radiating effect.  The process may be effected at atmospheric or raised pressure.  The hydrocarbon vapours may be condensed to yield lubricants and fuels, or they may be cracked without intermediate condensation, preferably after separating any entrained solids. The sludge or like residue is preferably fed to the retort in a subdivided condition, and if necessary it may be mixed with heavy oil obtained in the process or with another oil to produce an emulsion which can be sprayed into the retort.  When acid sludge is treated, it is preferably heated with an aqueous solution or suspension of a neutralizing agent, e.g. slaked lime, chalk, dolomite, magnesia or soda, and the excess of water then separated, before the sludge is fed to the retort.  The Specification as open to inspection under Sect. 91 states that the process may be applied to pitch, tar, heavy oils and other combustible substances. This subject-matter does not appear in the Specification as accepted.
