Title: An improved method of fireproofing solid combustible substances
IPC: D06M15/429
Filed: 1936-04-27
Abstract: Solid combustible materials such as wood or fabric are fireproofed by treatment with a condensation product of dicyanodiamide or a derivative thereof such as dicyanodiamidine, guanidine, biguanide, melam, ammeline, ammelide or melamine with an aldehyde, with or without the addition of combustion-retarding substances such as phosphoric acid, boric acid or hydrobromic acid or substances which prevent decay or combat vermin or insects.  In examples, fireproofing - compositions are prepared by (1) condensing formaldehyde and dicyandiamide in the presence of a solution obtained by inverting sugar with aqueous hydrochloric acid and adding phosphoric acid to the product, or (2) condensing formaldehyde with guanidine phosphate obtained by fusing dicyanodiamide with monoammonium phosphate.  The Specification as open to inspection under Sect. 91 refers in general to treating combustible substances with condensation products of aldehydes with compounds in which a carbon atom is linked by all its four valencies to nitrogen atoms.  This subject-matter does not appear in the Specification as accepted.

Abstract: 252,530. General Electric Co., Ltd., and Gossling, B. S. May 7, 1925. Fittings, internal; contents, viewing.-A packing for case fragile articles, such as large thermionic, valves, comprises an external frame, an internal frame or cradle holding the article, and means, arranged between the two frames, for damping out vibrations which might otherwise be transmitted to the internal frame or cradle; the means for damping out vibrations comprise, in part, devices normally tending to pull each end of the internal frame towards the adjacent end of the external frame and, in part, soft vibration-absorbing material adapted to act in compression between the two frames. As shown, a circular sheet of rubber 9, preferably puckered sheet rubber sponge known by the registered Trade Mark " Sorbo," is secured at or near its centre to each end 2 of the inner frame 1, and its edges are secured to the adjacent ends of the external frame 16 so that the sheets normally pull each end of the frame 1 towards the adjacent end of the frame, 16 but, if the case is dropped, the sheets act in compression and absorb vibrations. The rubber sheet may be secured at its edges to a board 14 by undercut clamps 13 and its tension may be adjusted by varying the number of discs 12 arranged between its centre portion and the end 2 of the frame 1 to which it is secured. The body of the valve is clamped in the frame 1 by fixed and adjustable cross-members 3, 4. In a modification, helical springs, the tension of which may be adjusted, are arranged between the corners of the frames and wads of soft vibration-absorbing material are placed between the ends of the frames. The top part of the external frame may be fitted with wire netting to facilitate inspection of the contents.

Title: Improvements in refrigerating machines of the absorption type
IPC: F25B15/10
Filed: 1929-04-18
Abstract: 334,964. Maiuri, G., and Bossini. R. F. April 18, 1929. Refrigerating, absorption systems for.-In continuous-cycle systems having parts in oper gas and liquid communication and operated solely by heating, the weak liquor from the main generator is heated in a further vessel to raise it to a higher level. In the system shown in Fig. 1, strong liquor passes from the absorber A through the inner pipe L of the heat-interchanger M to the main generator B, from which weakened liquor passes to a secondary generator Q fitted with a riser pipe N. The liquor passes from the top of this pipe N to an annular space R, and thence by pipe T, interchanger M and pipes C<1>, C<1> back to the absorber. The circulation may be regulated by adjusting the heat supply Y' to the secondary generator. Liquor may overflow from the space R to the main generator, and the gas evolved in pipe N passes to the rectifier D and to the condenser F with the main gas stream. Inert gas present in the evaporator-absorber side is heated in an ascending conduit H and cooled in a descending conduit K in known manner, and may be cooled in an interchanger I by the gas mixture from the evaporator E. In a modification several auxiliary generators in series are employed and the gas or solvent vapor evolved in the last stage is led to the absorber instead of to the rectifier. Ebullition of the solvent may occur in the last riser pipe.

Title: Improvements in thermally tripped electric switches
IPC: H01H71/16
Filed: 1948-05-04
Abstract: 651,883. Automatic circuit - breakers. SHARP, W. May 4, 1948, No. 12175. [Class 38(v)] A switch that opens automatically on the passage of excessive current comprises an insulating base 1 having a number of channels in each of which is a fixed contact 5 and a movable spring blade contact 3 which normally tends to separate from the fixed contact. Contact 3 is connected directly to a terminal 4, the contact 5 being connected to a terminal 10 through a heating wire 8 which is coiled round an insulating sleeve 9 surrounding a bi-metal strip 6. All the contacts 3 can be pressed into contact by a pivoted arm 11 carrying projection 13. When the arm is depressed, by a pushbutton 19, for example, it is held in the depressed position by a roller 14b on a swinging arm 14 which engages over an adjustable projection 16 on the arm 11. The arm 11 can be released, to allow the contacts to separate, by a second push-button 18 which when depressed bears against the arm 14 and swings it free of the projection 16. Excessive current through the switch also opens the contacts by heating the strips 6 and causing them to bend and move the arm 14 away from the projection 16. To prevent the switch from being closed before the strips 6 have returned to their normal positions a stop lever 21 is pivoted to the base and is connected by a spring 22 to the arm 14. When the arm 14 is moved by the bi-metal strips the lever 21 is brought into the path of a projection 23 on the arm  11 which cannot therefore be depressed.

A method for the continuous remote monitoring of the composition of air e.g. in mines for detection of methane, wherein air samples to be analysed are introduced into the gas collecting chamber K of a monitoring instrument connected to a point where air is to be sampled by a line L, comprises evacuating the chamber K before each measurement, by use of a pump P with a valve A closed and a valve B open, the evactuated chamber K being subsequently brought into communication with the line L by opening the valve A, with valve B closed, so that an air sample flows into the chamber K, the analysis of the sample then being carried out. A manometer M is provided for the measurement of gas pressures in the chamber K. Any number of lines L may be provided, each with its own connecting valve A. Various other arrangements of valves and connecting lines are described in the Specification whereby air may be continuously drawn through a line L by the pump P, samples being withdrawn from the air flow in the pipe line into the chamber K as desired. Connection may also be made to a source of gas which may be used as a flushing gas for various of the lines leading to the chamber K and the chamber itself. Furthermore, where the gaseous impurity in the air being tested is only present in very small quantities, a second pump may be interposed in the line between a valve A and the chamber K in order to introduce the air sample into this chamber after evacuation, at a pressure higher than atmospheric, whilst maintaining the required gas flow through the line L.

Abstract: 1,214,377. Digital facsimile transmission systems. XEROX CORP. 14 March, 1968 [17 March, 1967], No. 12513/68. Headings H4F and H4P. Different run lengths of binary data are represented by different frequencies, the frequencies being chosen in dependence on the probability of occurrence of the run lengths, so that the highest frequency represents the run length most likely to occur and the lowest the least likely. The data is facsimile data in the embodiment described. Transmitter.-The binary data from the document scanner passes to a unit which develops positive and negative ramp voltages whose final amplitudes depend on the length of the corresponding run of 1 and 0 bits, respectively. Each bit transition, marking the end of a run length, gates the ramp voltage and the resulting multi-amplitude samples are passed to successive stages of a capacitor buffer store. When the store is 0À6 full it is read out to a magnetic tape store. When the document scan has been completed the tape store is read out to a unit which develops and transmits frequencies dependent on the amplitude of the stored signals, the amplitude/frequency relationship being as defined above. Receiver.-The received signals pass to a comb filter which feeds a unit generating a multiamplitude signal identical to that at the transmitter. This signal is stored on a magnetic tape recorder, and at the end of the message the recorder is read out and the multi-amplitude signals stored in successive stages of a capacitor buffer store. The buffer store is subsequently read out to a unit which generates a run length signal of length and bit state appropriate to the multi-amplitude signal; the resultant signals are fed to a facsimile reproducer.
