Title: Improvements in or relating to electric fire and temperature alarms
IPC: G01K3/12
Filed: 1933-08-30
Abstract: 412,797. Fire and temperature alarms. BLOCH, F. G., 4, Meisslergasse, Leitmeritz, Czecho-Slovakia. Aug. 30, 1933, No. 24089. [Class 47 (i).] In a device for operating electric fire and temperature alarms of the kind comprising two coacting indicating thermometers of different reactional velocity, having co-axial pointers moving in substantially the same plane or in parallel planes over a common scale and being provided with electric contacts, the pointer of the more rapidly reacting system being located on the rear of the other pointer, both pointers are actuated by temperature-sensitive bimetallic strip helices to which they are connected by floating spindles. In the construction shown, a base plate F, for attachment to the ceiling of a room, supports an alarm device comprising two bi-metallic springs B, G provided, respectively, with co-axial pointers D, J movable over a dial C, the spring B having a lower reactional velocity than that of the spring G. The pointers D, J are connected to terminals N, L, respectively, which are in circuit with an electric alarm. Each spring has a flexible zero-point adjustment T.. The pointer D indicates the temperature prevailing in the room, while the pointer J is set to a lower temperature. A third pointer Q is provided which is set to the highest permissible temperature, the pointer being adjustable by means of a pinion R and a toothed disc S. When the alarm is exposed to the influence of a sudden rise in temperature, the pointer J moving more quickly catches up with the pointer D and thus completes a circuit to operate the alarm. In the case of a gradually smouldering fire, the pointers D, J do not come into contact until they are both stopped on reaching the limit set by the pointer Q. Specification 378,314, [Group XX], is referred to.

Abstract: 171,207. Automatic Telephone Manufacturing Co., Ltd., and Roseby, P. N. Aug. 21, 1920. Resistance furnaces. -A resistance furnace of the type in which the resistance is wound round the outer surface of the heating chamber has the resisting element formed of iron wire, oxidation of the element at high temperatures being prevented by maintaining an atmosphere of hydrogen around it. The furnace rests on a block of fire-brick 1 and comprises three concentric chambers 2, 3, 5, of which the chamber 2 forms the heating space, the chamber 3 contains the resistance and the chamber 5 is filled with insulating material 6. The chamber 3 has walls of fire-bricks cemented together, the inner having grooves in the bricks to contain the iron wire resistance. The grooves in the hexagonal furnace shown are arranged to run downwardly diagonally across the layers of bricks on two sides of the furnace in succession and then upwardly at an equal inclination on the next side, this arrangement being repeated for the other three sides so that the grooves form a two-threaded screw round the inner wall of the chamber 3. Two wires are laid in parallel in the grooves, and current is passed through one wire only until the furnace is heated up when the other wire. also is utilized. Hydrogen preferably obtained by electrolyzing acidulated water is constantly supplied to the chamber 3 through pipes 4. The outer wall 8 of the furnace is formed of sheet iron and the heating-chamber is closed by a fire-clay lid 9 having an iron handle 10 and provided with an aperture 11 through which the interior of the furnace may be observed or a pyrometer inserted. The walls of the furnace may be formed by silica tubes in place of fire-brick. According to the Provisional Specification an inert or a reducing gas may surround the resistance.

Abstract: Pterins having in one tautomeric form the formula <FORM:0648896/IV (b)/1> wherein R represents OR1 or NR2R3, R1\h being hydrogen or an alkyl group, R2 is hydrogen and R3 is an amino acid residue, by admixing: (1) 2:4:5-triamino-6-hydroxypyrimidine, or a tautomer thereof; (ii) a 1:1:3-trihaloacetone; (iii) para-aminobenzoic acid or a salt thereof or the corresponding aliphatic ester or amino acid amide thereof or a salt of such amide to give the desired R substituent. The process may be carried out by first admixing reactants (i) and (ii) and then adding (iii), or by first admixing reactants (ii) and (iii) and then adding (i).  Suitable 1 : 1 : 3-trihaloacetones are 1 : 1-dichloro - 3 - bromo -, 1 : 1 : 3 - trichloro-1 : 3 - dichloro - 1 - bromo - and 1 : 1 : 3-tribromo-propanones-2.  The preferred amino acid amide is that of glutamic acid but other amino acids amides may be used, e.g. those of glycine, aspartic acid, leucine, alanine, isovaline, cysteine or glutamylglutamic, or glutamylglutamylglutamic acid.  Diethyl p-amino-benzoylglutamate may be used as reactant (iii).  The reaction may be carried out in an aqueous medium within the pH range of 1 to 5.  In the examples, pteroylglutamic acid is prepared.  The sample furnished under the provisions of Sect. 2 (5) comprises the sodium salt of pteroyl-glutamic acid.  The Specification as open to inspection under Sect. 91 refers to the preparation, by the above method, of compounds of the above general formula wherein the group -COR may be attached to any position of the phenyl ring, wherein R is OR1 or NR1R11, R1 and R11 being hydrogen, aromatic or aliphatic radicals.  Reactant (iii) may also be any amide of any aminobenzoic acid including diethyl p-aminobenzoylglutamate.

Patent GB-463795-A (GB)
Title: Improvements in and relating to electric communication systems
IPC: H04B3/20
Filed: 1935-09-04
Abstract: 463,795. Two - way transmission. TELEPHONE MANUFACTURING CO., Ltd., and PADDLE, L. H. Sept. 4, 1935, No. 24653. [Class 40 (iv)] In a system employing voltage-controlled attenuators, control is effected by a pair of anode bend rectifying valves and further rectifying means arranged so that signal input to one valve causes increase of its anode current and decrease of anode current of the other valve. In the arrangement shown in Fig. 2, part of the signal input to V1 is rectified at 27 to decrease the normal negative bias on the valve and the alternating component of the anode current is applied over transformer 12 to rectifier 20 which increases the negative bias on V2. Signal input to V2 has opposite effects. The attenuating networks T1, T2 may be connected directly in the anode circuits or may have control voltage applied to them over resistance networks 26. The resistances 22, 23 applying negative bias to the valves in response to signals may be variable. In a modification, Fig. 1 (not shown), the rectifiers 27 are replaced by rectifiers fed by additional secondaries of transformers 12, 13 and applying positive bias across resistances in the grid circuits of the valves. In the loud-speaking telephone circuit shown in Fig. 3, the networks T1, T2 may normally be biassed to have equal attenuations or so that the attenuation of T2 is greater than that of T1. Incoming voice currents cause valves V1, V2 to reduce and increase the attenuations of T1, T2 respectively and microphone currents have the opposite effect. The distant speaker may break in by shouting. To prevent interference by noise picked up by the microphone when the loud-speaker is in operation, additional bias may be placed on V2 by rectification of current in the loud-speaker circuit. A two-way repeater, Fig. 4 (not shown), has control arrangements similar to Fig. 3. In the four-wire circuit shown in Fig. 5, each terminal has an attenuator T2 in the go path and in attenuator T1 in the control path. Voice currents from the two-wire line at H reduce the attenuation of both T1 and T2 and at the distant end increase the attenuation of T1 and T2 associated with the opposite path. In carrier working, the supply of carrier current to the modulator may be controlled by an attenuator in response to modulating signals. The increase in current of one of the valves at a distant carrier terminal or the distant end of a four-wire circuit may be used for calling by intermittently operating a relay in its anode circuit in response to the application of interrupted carrier or voice frequency at the calling end. The relay operates the calling device through one or more slow operating relays which prevent the device operating on interruptions in speech. Specifications 451,496 and 459,779 are referred to.
