Abstract: Substantive water soluble azo-dyes are prepared by acylating aromatic diamines or aminohydroxy compounds containing or not sulpho groups with carboxylic acids of the general formula R--(CH=CH)x--COOH, their esters, halogenides or anhydrides wherein R stands for an unsubstituted aromatic hydrocarbon residue and x for 1 or 2, and either diazotizing the free amino group and coupling the diazonium compound with azo components or coupling the acylated products with diazonium compounds. Suitable carboxylic acids are cinnamic and cinnamal-acetic acids (the latter being the condensation product of cinnamaldehyde and acetic acid).  In examples: (1) p-phenylenediamine is condensed with cinnamoyl chloride and the monacylated diamine diazotized and coupled with R salt (dyes cotton and viscose artificial silk violet); the diazo body may also be coupled with 1 - naphthol - 3 . 6 . 8 - trisulphonic acid, 2 - naphthol - 3 . 6 . 8 - trisulphonic acid, 1 . 8 - aminonaphthol - 3 . 6 - disulphonic acid; (2) 1 . 8 - aminonaphthol - 3 . 6 - disulphonic acid is condensed with cinnamoyl chloride and coupled with diazotized aniline (dyes red); (3) Gamma acid is condensed with cinnamalacetic acid chloride (prepared by action of thionyl chloride on the acid) and coupled with diazotized metanilic acid (dyes scarlet red); (4) Gamma acid is condensed with cinnamoyl chloride and coupled as in (3); (5) J acid is condensed with cinnamoyl chloride and coupled with diazotized naphthionic acid (dyes red shades).

IPC: H04M1/02
Filed: 1924-10-15
Abstract: 244,858. Graham, E. A. Oct. 15, 1924. Condensers; transformers. - In an associated telephone receiver and transformer as used for example in the anode circuit of a terminal therm. ionic valve of a wireless receiver or amplifier, both the receiver and the secondary of the transformer have operative windings, the self-capacity and ohmic resistance of which are negligible as compared with the inductance. Particulars are given of the windings of an auto-transformer, the secondary of which has a resistance of three ohms and of a telephone receiver with the same resistance. The secondary winding may be connected with the telephone receiver at one or both poles through considerable capacity. This capacity may be constituted by the secondary winding, which is formed of two strips of copper or tinfoil separated by dielectric, the inner end of one strip and the outer end of the other constituting the terminal of the capacity. The primary winding of the transformer may be provided with tappings so that a variable number of turns may be included in the circuit of the valve. Provision may be made for short-circuiting or shunting by a resistance a varying number of such turns.

Title: Improvements in or relating to the shaping of articles of hosiery
IPC: D06C5/00
Filed: 1954-08-24
Abstract: <PICT:0760447/IV(b)/1> <PICT:0760447/IV(b)/2> An apparatus for shaping hosiery comprises a sealable chamber into which the articles are placed on shaped forms in dry condition, they are then pre-heated, steamed under reduced pressure, and after discharge of the steam are dried.  Figs. 2 and 3 show a hosiery processing machine comprising an insulated processing chamber 7 the ends of which can be tightly sealed by automatically operated doors 8.  The forms 21 have socks mounted upon them and are supported on flaps Figs. 5 and 6 (not shown) on form carrying frames 5, 6 so that by rotation of the turntable 4 a set of forms is introduced into the chamber 7 and a second set removed at the completion of the process on them.  With doors 8 closed, valve 12 in its full line position (Fig. 3) and valve 15 being open fan 11 is operated so that air flows by heating resistors 9 passes round the set of forms in chamber 7 and returns to the fan 11 via ports 13 and manifold 14.  On completion of this pre-heating process which may take from 30 seconds to 4 minutes, valve 15 is closed, valve 12 is moved to the dotted-line position (Fig. 3) and steam is passed into chamber 7 so that a pressure of from 5 to 100 grams per sq. cm. above atmospheric is set up therein. When the steaming operation has been completed valve 15 is opened to allow the steam to discharge and a vacuum to be established in the chamber.  Valves 12 and 15 are then returned to the initial position and drying is carried out by passing hot air through chamber 7 as in the initial pre-heating process.
Patent GB-1190495-A (GB)
Title: Improvements in or relating to Waveguide Filters
Inventor: CRAVEN GEORGE FREDERICK
IPC: H01P1/219
Filed: 1968-05-23
Abstract: 1,190,495. Microwave filters. STANDARD TELEPHONES & CABLES Ltd. 23 May, 1968, No. 24693/68. Heading H1W. A waveguide bandpass filter utilizes a length of square- or circular-section waveguide having a cut-off frequency above the operating frequency and capable of supporting evanescent H and E waves, the waveguide being provided with obstacles each having a capacitive reactance which is the conjugate of the positive imaginary characteristic impedance which the waveguide presents to evanescent waves. The cut-off waveguide 3 is connected at either end to propagating H 01  mode rectangular guides 1, 2 and consists of three sections of length l. The inner section is provided with a single capacitive screw (or iris) 6 and the two outer sections with opposed capacitive screws 4, 5. Screws 7 are for matching purposes. If each screw 4, 5, 6 is adjusted to provide a capacitive reactance conjugate to the inductive reactance of the respective section, it can be shown that each section behaves as a passband filter. Apart from this, the filter has additional properties caused by the transformation of the incident H 01  (or H 11 ) mode energy into E 11  (or E 01 ) mode energy by the capacitive obstacles 4, 5. It is shown in the Specification that an equivalent circuit which takes into account the effect of the evanescent E mode wave includes a parallel resonant circuit in the series branch, whereby the possibility of a rejection frequency arises. The frequency at which rejection occurs depends upon the H-#E transformation ratio determined by the screws 4, 5 and the sign of this ratio depends upon the polarity of the E mode relative to the incident H mode. This, in turn, depends upon which side of the centre-line of the guide the gap between screws 4, 5 is situated. Thus, the rejection frequency may be shifted by adjusting the relative penetration d 1 , d 2  of the screws 4, 5. Thus, the lowest rejection frequency is achieved with d 2  = 0 and D 1  = max., i.e. with all the screws on one side of the guide. With screws on alternate sides of the guide (d 1  = 0) the rejection frequency is more remote from the passband. To achieve a controllable rejection frequency, two sections are necessary, one with a single obstacle and the other with a pair of opposed obstacles, but the order in which they occur is not significant. Thus screws 4, 5 may be interchanged with screw 6 in the illustrated embodiment.

The products are perferably hydrogenated to convert high molecular weight aldehydes and unsaturated alcohols which are obtained as by-products to the required product alcohols; the alcohols may then be recovered by distillation.
Patent GB-247391-A (GB)
Abstract: 247,391. Rushworth, W. Feb. 18,1925. Two-stroke engines. - The charge compressed in the crank case is transferred to the combustion chamber through a valve 17 in the piston opened by the angular movement of the connecting-rod. A tappet 23 mounted on the gudgeon pin 21 has projections 24 engaged by abutments on the small end of the connecting-rod, and another projection 25 engaging a lug 34 on a valve rocker 30. The arrangement is such that, as the connecting- rod swings outwards on the down-stroke of the piston, bevelled surfaces on the projections 25 and 34 slip past each other without opening the valve, the tappet 23 moving axially against a spring to allow of this, while as the connecting-rod swings back to its central position during the lower part of the stroke, the projections 25 and 34 so-operate to open the valve, which becomes again closed at the bottom deadcentre. The rocker 30 is weighted at 31 to provent the valve from opening against the action of its spring when the movement of the piston is reversed at the end of its stroke. Combustion chamber, shape of.-The cylinder head is formed with curved portions 10 extending outwards from a central projection 8, so that the charge entering through the valves 17 and imping- ing on the projection 8 is then directed outwards along the curved portions 10 and down the cylinder walls so as to scavenge the 'burnt gases.
