Title: Improvements in or relating to awnings, sun blinds and the like
IPC: E04F10/06
Filed: 1948-06-09
Abstract: 643,624. Lath for sun blinds &c. ARTISTIC BLIND CO., Ltd., and HEWSON, P. C. June 9, 1948, No. 15567. [Class 20(iii)] [Also in Group XXIII] A lath or rail 1 for a sun blind or awning has a tensioning wire, cable or the like 4 extending along a substantial part of its length and anchored to a bracket 2 adjacent each end of the lath, and a plurality of plates, lugs, projections or the like 6 mounted intermediate the brackets and serving to engage the wire so that when the latter is tensioned a component B of the tension A will tend to move the lath intermediate the brackets in a direction which will counter-act any sagging or bowing. The lath may be of wood, metal, or other suitable material. The cable may lie in a groove 5 in the lath and connect to eye bolts 3 passing through the brackets, and be tensioned by means of nuts 7. A wooden block 8 at each end enclosing the end of the cable and screwed to the lath is preferably of similar section to a tacking fillet 9, and serves to locate the fillet and reinforce the brackets. The fillet 9 is first sprung into position, the cable tensioned, and the fillet then secured by screws. Sagging or bowing in two planes may be counteracted by using two cables each acting in a different plane, and disposed on the same or different surfaces. The invention may be applied to Dutch blinds.
Patent GB-1570760-A (GB)
Title: Closed layer chromatography process
IPC: G01N30/94
Filed: 1977-04-14
Abstract: The novel method combines individual advantages of the known layer chromatography and column chromatography, their disadvantages being substantially eliminated. In particular, the separation capacity of layer chromatography improves with easy identification of the separated materials remaining unchanged. The advantages of column chromatography, such as the reliable quantification, the high separation capacity already mentioned and the short separation time are likewise achieved. The novel method is carried out with simultaneous forced flow, analogous to column chromatography with an eluent, the adsorption layer applied to the support plate being sealed off by a cover plate. As a result, the free vapour space above the adsorption layer, as in the column chromatographic method, is eliminated. After charging the eluent, lifting off the cover plate, drying and development with colour reagent are carried out.

Abstract: 645,616. Frequency measurements. STANDARD TELEPHONES & CABLES, Ltd. June 19, 1947, No. 16206. [Class 37] Apparatus for measuring the frequency of an A.C. supply consists of means for translating the frequency to a higher frequency, which is transmitted along a line, together with other signals, to be separated out at the receiving end and made to operate a suitably calibrated detecting device, employing band-pass and band-stop filters at each end. The frequency translation may be effected by a synchronous motor-generator, or by choosing a harmonic of the supply frequency. Another method of frequency changing for a 3-phase system, Fig. 3, consists of combining the output of all three phases after full wave rectification so that the nominal 50 c/s. becomes a nominal 300 c/s. ripple. At the receiving end, Fig. 4, by injecting a local frequency, the variations of the 50 c/s supply may be amplified and shown as a suitably calibrated indicator. The local oscillator may be controlled by a master oscillator, or its frequency may be controlled from the sending end, to neutralize errors introduced by the transmission line.
