Patent GB-710730-A (GB)
Title: Improvements in or relating to directional radio antennae
Inventor: SCHNEIDER ADAM BRONISLAW
IPC: H01Q19/13
Filed: 1952-01-17
Abstract: 710,730. Aerials. DECCA RECORD CO., Ltd. Jan. 16, 1953 [Jan. 17, 1952], No. 1416/52. Class 40 (7). A directional radio antenna system consists of a primary element directed into a reflector of dimensions large compared with the wavelength to be radiated or received wherein the reflector comprises a substantially continuous conducting surface with holes or slots therein to permit the passage of radio energy so as to reduce the amplitude of the energy reflected from preselected regions of the surface. Where it is desired to produce a single lobe aerial system with the minimum of side lobes it is usually very difficult to obtain a primary radiator with exactly the correct energy distribution and the present invention enables the correction necessary to be made at the reflector. If the holes or slots are resonant at the frequency of the system any phase changes are avoided. Fig. 1 shows a " cheese " type of reflector and a horn primary element 13, to counteract the radiation of more energy to the sides of the horn than is desirable to give the minimum side lobes the parabolic surface 10 of the reflector is provided with holes 14 increasing in number towards the edges. To control the radiation passing through the reflector and prevent this having an adverse effect on the overall pattern the energy may either be absorbed or reflected by a surface at 45 degrees to the back of surface 10 so that it is directed, for example, vertically upwards in the case of a horizontal cheese, Fig. 3 (not shown). If the energy is to be absorbed this may be done by placing a sheet of absorbing material at a convenient distance behind the holes or slots and backing this by a reflecting surface threeeighths of a wavelength further back, Fig. 4 (not shown), or by attaching a waveguide having an energy absorbing filling to the rear of each hole, Fig. 5 (not shown). The sizes of the holes may be so chosen that they act as capacitive or inductive reactances and so affect the phasing of signals directed to or from different parts of the reflector.

Patent GB-752875-A (GB)
Title: Tanning agents and process for producing same
IPC: C14C3/18
Filed: 1953-01-19
Abstract: Tanning agents which are condensation products from a polyhydric phenol, an amine or ammonium salt and an aldehyde, as described in Specification 747,092, are prepared in solid form by carrying out the condensation in a concentrated solution of an alkali metal nitrate or halide, the anion of the salt being the same as that of the salt of the nitrogenous base.  The preferred reaction medium is saturated or nearly saturated brine.  After precipitation of the resin, the mixture is cooled, the salt solution decanted off and the soft mass pressed to remove occluded solution.  Subsequent kneading with water removes still more salt.  Further small quantities of resin can be precipitated from the salt solution with alkali, filtered and dissolved in hydrochloric acid.  In place of pure polyhydric phenol acidified solutions of the alkali salts of benzene-1,3-disulphonic acid (used for the preparation of resorcinol) may be used directly after removal of excess sodium chloride by filtration and of sulphur dioxide by boiling.  Examples describe the preparations of resins from (1) and (2) resorcinol, ammonium chloride and formaldehyde in saturated sodium chloride solution.  Using ammonium bromide the medium is saturated sodium or potassium bromide solution, and with ammonium nitrate, it is saturated potassium nitrate solution; (3) resorcinol, 2-aminoethanol hydrochloride or hydrobromide and formaldehyde in saturated sodium chloride or bromide solution; (4) resorcinol, aniline hydrochloride and formaldehyde in saturated sodium chloride solution; (5) catechol, ammonium chloride and formaldehyde in sodium chloride solution; (6) catechol, 2-aminoethanol hydrochloride and formaldehyde in saturated sodium chloride solution; (7) pyrogallol, aniline hydrochloride and formaldehyde in saturated sodium chloride solution; (8) and (9) a crude resorcinol solution saturated with sodium chloride, ammonium chloride and formaldehyde solution.  Examples (10) and (11) are similar to (8) and (9) but employ 2-aminoethanol hydrochloride and aniline hydrochloride respectively as the salts of bases.
