Abstract: 728,984. Fire-resisting doors. MANNESMANN AKT.-GES. Feb. 13, 1953 [Feb. 15, 1952; July 25, 1952], No. 4157/53. Class 20 (3). A fire-proof door for airraid shelters comprises two layers 33, 34 of fire-resisting material made of gypsum with a support of fibrous material or cardboard and secured together, e.g. by glue, the layers being enclosed by steel plates 35, 36 joined, preferably by welding, at the edges to form a stop flange 37 which when the door is closed contacts limbs 20a, 20b of a door frame 20. The door is equipped with three latch-type locks disposed half-way up, at the top, and at the bottom of the door and operated together by a bar 25 having slots 28 to engage operating pins 29. The bar is accommodated in a channel 26 which is accessible  by means of one or two cover plates, not shown, which close one or both ends of the channel. The locks are introduced through openings in the front vertical rail of the frame, the middle lock being secured to the vertical rail of the frame by straps 30 and the upper and lower locks, the lower lock not being shown, being secured by straps 31 to the vertical rail and by screws 32 to the horizontal rail of the frame. In a modification the door consists of two layers of fire-resisting material having a frame Z- shaped in cross-section and a steel plate on the outside of the door which is folded over the frame at the edges. The door is reinforced with transverse bars of Z-section which are secured by one limb, e.g. by spot welding, to the steel plate, another limb engaging between the two layers of fire-resisting material. In an alternative arrangement the frame is of T-section and the steel plate is arranged on the inside of the door. In a further modification the door consists of three layers of material and the frame is composed of a combined Z- and a T- section, the steel plate being located between two of the layers of material and the Z reinforcing bars being secured to the plate. The reinforcing bars may be used as supporting means for locks or bolts.

The lamp-socket 14 is a press fit in a translucent ring 16. A transparent spacer sleeve 18 carries at its upper end a metal contact button 22 having inner concave surfaces which serve as reflectors. A concave reflector 20 surrounds the sleeve 18 and is engaged by a spring 24 which bears against a metal cross-bar 26, so as to keep the button 22 normally out of contact with the bar 26. A colour screen 44 is included in the path of the reflected light which illuminates the translucent ring 16, unreflected light being prevented from passing to the front of the panel. To test the lamp, its base 12 is pressed so that the button 22 engages the bar 26 and closes a circuit through the lamp and battery 36. If the lamp is defective it can be removed and replaced from the front of the panel. In a modification the illuminated part is in the form of a bulls-eye above the lamp instead of a ring around it.

[Class 40 (v).] In a wireless receiver the detector serves only as a demodulator and the damping of one or more high h frequency circuits is reduced by a reactive coupling from a low frequency amplifying valve to which high frequency energy is supplied. The Figure shows a detecting valve 1 and a low frequency amplifying valve 2 to which high frequency energy is applied by condenser 7. The reactive coupling 9, 10 serves to reduce the damping of the tuned circuit 3, 4. To exclude high frequency energy from the couplings 5, 6 chokes 12, 13 and condenser 11 are provided. In a modification, Fig. 2 (not shown) an inductive coupling to the circuit 3, 4 supplies high frequency energy to the low frequency amplifying valve. When a tuned grid coupling is employed the high frequency energy may be taken from the anode of the preceding high frequency amplifier. A screen-grid valve or a pentode may be used as the detector.

Patent GB-728594-A (GB)
Title: Purification and hydrolysis of esters of folic acid
IPC: C07D475/04
Filed: 1952-02-22
Abstract: Folic acid is prepared by contacting a crude di-alkyl ester of folic acid, or an acid addition salt thereof, with hydrochloric acid having a concentration of between 3.6 and 4.4 normal whereby the ester and some of the impurities are dissolved, separating the solution from undissolved matter, decreasing the acid concentration to about one normal or less, and allowing the solution to stand for an appreciable period whereby folic acid forms and precipitates from the solution. A preferred hydrochloric acid concentration is 4 normal.  The treatment with the hydrochloric acid may be for a period of about fifteen minutes to about two hours, and the final solution may be allowed to stand for a period from about 12 to about 48 hours.  After separating the insoluble impurities, the solution may be diluted with three volumes of water and the hydrochloric acid partially neutralized with sodium hydroxide before allowing the folic acid to separate. The hydrochloric acid concentration may be reduced to a strength of about 0.1 normal to allow the folic acid to separate. About 25 to 200 ml. of hydrochloric acid per gram of folic acid ester may be used to effect the initial separation of impurities, e.g. about 25 to 50 mls. of hydrochloric acid can be used in which case the acid concentration may be reduced to between 0.05 and 0.4 normal by the addition of aqueous sodium hydroxide.  The dimethyl, diethyl, dibutyl and diiso-octyl esters of folic acid may be treated by the above process.  In the examples folic acid is prepared from crude diethyl ester of folic acid.  Specifications 675,383 and 712,762 are referred to.  Dialkyl esters of folic acid are prepared by esterifying folic acid with anhydrous alcohols in the presence of hydrogen chloride, or by reacting a pteridine of the general formula <FORM:0728594/IV (b)/1> wherein Z represents an arylsulphonyl radical and R represents an alkyl radical, with hydrogen bromide and a bromine acceptor in a lower aliphatic carboxylic acid.
