The side 2 of the frame is inclined. Two opposite sides of the frame may have spreading edges 3 and may be of salient, Fig. 2, or re-entrant shape. The edges 5 have wear strips 5a. An adhesive tape may be put on the joint first. According to the Provisional Specification an applicator comprises a box open on two adjacent faces, the longitudinal edges of the side walls of the open faces being inclined for engaging the wall boards and a transverse edge at the end of the inclined edges being chamfered for a spreading edge. The spreading edge may be concave or of salient or re-entrant V-shape. The spreading edge may be on the edge of a side wall of the open faces.
Patent GB-686014-A (GB)
Title: Improvements in and relating to transmitters and receivers for frequency-modulated waves
IPC: H03C3/06
Filed: 1950-03-21
Abstract: 686,014. Frequency modulation; radio signaling. SOC. FRANCAISE RADIO-ELECTRIQUE. March 21, 1950 [April 14, 1949], No. 7086/50. Class 40 (v). Frequency-modulated waves I of mean frequency f are converted to frequencymodulated waves II of different mean frequency f2 and different frequency deviation, e.g. for frequency deviation compression and expansion, by employing an oscillator P with input and output oscillatory circuits tuned to frequency f2 coupled together through a delay network 8 producing a phase-shift n# (n an integer) at the frequency f2, and varying the phase-shift by successively beating the input and output from the network by the frequency-modulated original wave I of frequency f<SP>1</SP> #f1. The difference frequency is taken as the input to the delay network and depending on whether f is less than or greater than f2 frequency compression or considerable expansion can result. For U.H.F. transmitters the wave I can be produced by reflector electrode modulation of a reflex klystron and wave II by a back-coupled travelling wave valve, at the receiver corresponding frequency compression being produced. The arrangement may be applied to a relay station, the received wave being used as wave I, and the transmitter being a travelling wave valve or a klystron. In Fig. 3 (not shown) the input wave I passes to a wave-guide T-junction, opposite arms of which are connected to opposite ends of a delay line associated with crystal mixers to and from which are connected the output and input of a travelling wave amplifier back-coupled to form an oscillator having an output horn aerial. The delay line has to pass only beat frequencies and may be a section of cable of high dielectric loss, or an air dielectric twin wire cable spaced by dielectric discs forming a line of low cut-off frequency. Specification 556,208 is referred to. Reference has been directed by the Comptroller to Specification 534,955.

Title: Improvements in smoke alarms
IPC: G01N7/10
Filed: 1923-03-12
Abstract: 221,523. Simpson, C. A., and Marklund, C. O. March 12, 1923. Indicating presence of gases. - Electric smoke alarm apparatus is energized by an alternating electric current from a main source of supply reduced in voltage and used in combination with means automatically to change to a stand-by on the main current failing. The smoke-laden atmosphere around a porous vessel causes a partial vacuum therein and in consequence electric contact is made in a diaphragm vessel 13 connected to the porous vessel by tubing. Current can then pass from a transformer 12 on the communicator board to operate an indicator 6, a transmitter drop switch 5, 5A, 5B and a bell relay 4. The indicator 6 brings a lamp 7 into circuit by a knife switch 6A, 6B. The closing of the transmitter drip switch 5, 5A, 5B causes the transmitter 10 to send a message to the fire station. The bell relay 4 operates a make-and-break to ring an alarm bell 9. Any number of porous smoke diffusers may be used, the diaphragm chambers 13, indicators 6 and lamps 7 being multiplied accordingly and connected up in the circuit. When the current fails the change-over switch 2 is operated and brings into circuit, the battery 11 and also a lamp 3 which indicates that the change has occurred.

Title: Feedwater control system for a steam generator
IPC: F01K13/02
Filed: 1974-09-03
Abstract: 1486570 Controlling feedwater to boilers BABCOCK & WILCOX CO 3 Sept 1974 07148/77 Divided out of 1486569 Heading F4A [Also in Division G3] The supply of feedwater to a steam generator is controlled by a demand signal which is modified by a signal representing the amount by which the actual temperature of the water deviates from a desired temperature set by the demand signal. The control is applied to a two boiler single turbine installation having the individual boiler demand signals derived as a ratio of a total demand signal which forms the subject-matter of parent Specification. As shown, the demand signal for boiler A is supplied to the feedwater control valve 74A through sumation elements 87A and 82A and is also supplied to function generator 83A which produces a reference temperature signal. The comparator 86A compares the actual temperature from 84A with this reference and after modification at 88A to account for the steam temperature a signal is added into the valve control signal at 87A to provide a desired flow signal to the retroactive loop controlling valve 74A.

Title: Improvements in the development of blue prints
IPC: G03C1/64
Filed: 1933-03-10
Abstract: 416,489. Photographic blue - print processes. MURRAY, H. D., and SPENCER, D. A., 118, Fulham Road, South Kensington, and NORTON & GREGORY, Ltd., Castle Lane, Buckingham Gate, both in London. March 10, 1933, Nos. 7317 and 18410. [Class 98 (ii).] Stable ferro-prussiate prints are obtained, without the usual washing step, by subjecting the exposed prints to surface treatment with a solution containing an agent which chemically fixes any ferric salt and/or ferricyanide. Thus ferric salt may be fixed by spraying over the paper with a dilute solution of a weak alkali such as borax or alkali perborate or with orthophenanthroline. Better results are obtained by fixing excess ferricyanide, e.g. by means of a solution containing a nickel, zinc, manganese, cadmium or cobalt salt. The fixing solution may contain an oxidizing agent and a buffer reagent ; and may also contain a dye, e.g. tartrazine, of a colour complementary to that of Prussian-blue, giving bright yellow lines upon a green background. Exposed prints may be treated with an oxidizing agent in addition to a fixing agent. A paper containing an excess of ferricyanide is produced by coating paper first with a ferricyanide solution, drying, and then coating with a solution of ferric ammonium oxalate. In examples, the exposed paper is treated with solutions containing: (1) manganese sulphate; (2) nickel sulphate and potassium persulphate ; (3) zinc chloride, potassium persuphate and sulphuric acid ; (4) nickel sulphate, ammonium persulphate, ammonium dihydrogen phosphate, diammonium hydrogen phosphate, sodium bisulphate and sodium chlorate ; and (5) nickel sulphate, ammonium persulphate, potassium dihydrogen phosphate, diosdium hydrogen phosphate, and sodium bisulphate ; the last example being applied to a paper containing an excess of ferricyanide formed by the double coating process.

In the treatment of molten glass, gas bubbles 34, 36, 38 are released from at least three spaced points 26, 28, 30 in the floor 24 of the container, the points forming a closed configuration so that the streams of bubbles rising therefrom co-operate with one another to produce a steady rising stream 40 of glass which fans out at 42 and continuously breaks the surface of the molten glass. Fig. 3 shows the points at the corners of a triangle ; when more points are used they may be arranged at the corners of a square, or at the corners and within polygous, or around the circumferences of concentric circles of different radii. The points are preferably spaced from one another by a distance equal to approximately twice to four times the diameter of the bubbles at the time of their release. The bubbler tube may be of an erosion-resistant refractory e.g. zirconium aluminate which may extend into the glass or it may be of metal e.g. platinum or molybdenum which may terminate flush with the base of the glass container which may then be formed with a refractory insert around the tube. The tube may have a cooling jacket and may be provided with a heating chamber to facilitate the removal of the tube from the container by melting the glass in the annulus in the base around the bubbler tube.
