Title: Improvements in or relating to electrical frequency determining apparatus
Inventor: WALLS WALTER RICHARD
IPC: G01R23/10
Filed: 1954-04-09
Abstract: 779,234. Frequency measurement. CINEMATELEVISION, Ltd. April 7, 1955 [April 9, 1954], No. 10498/54. Class 37. Frequency measuring apparatus comprises a counter chain indicating the number of cycles of a signal applied thereto during a known time interval over a restricted frequency range, a circuit for heterodying a received signal by one of plural locally operated oscillations selected by a switching device to develop a beat signal within the restricted range so that one or more digits of the frequency indication depend upon the count and on the frequency of the local oscillation, and means whereby the counter display is operated also by the switching device so that the local oscillation frequency is added to the count. In Fig. 1, an unknown frequency signal is connected over terminal 1 and the first contact of section A of switch 2 to a shaping circuit 3 devising corresponding short pulses energizing a gate circuit 4 opened for a predetermined time (e.g. 1 sec.) by a 1 Mc/s pulse source 26 controlling a series of 6 cascaded decade counter circuits 27-32 through timing circuit 5 which delivers an initial control pulse opening gate 4 at the commencement of a measurement cycle and receives a feed-back pulse from the final decade counter circuit 32 at the completion of 106 cycles to deliver a final control pulse closing the gate after a 1 sec. interval. The resultant pulse train at the unknown frequency is counted by a series of 8 cascaded decade counter circuits 6-13, each having a meter 14-21 registering the corresponding digit of the counted frequency valve (Fig. 2, not shown), for frequencies up to e.g. 6.1 Mc/s, and at the closure of gate 4 timing circuit 5 delivers a further control pulse resetting counter circuits 6-13 in readiness for a subsequent measurement. For input frequencies in the range of e.g. 6.1-11.2 Mc/s, 11.1-16.2 Mc/s and 16.1-21.2 Mc/s the input signal is applied over the second, third or fourth contacts of section A of switch 2, operated manually, or automatically by triggering means of the kind set forth in Specifications 747,489 and 749,060, to a mixer 22 also receiving local frequencies of e.g. 6, 11, or 16 Mc/s from generator 23 over the corresponding contacts of section B of switch 2, and the resulted heat frequency is applied to shaping circuit 3 through band-pass filter 24 having pass-band of e.g. 0.1-5.2 Mc/s, while corresponding contacts of section C of switch 2 selectively open a gating circuit 25 to impulse decade counter units 12, 13 (Fig. 3, not shown), so that their associated meters 20, 21 read 6 Mc/s, 11 Mc/s or 16 Mc/s at the commencement of each measuring time interval and the gross reading of the series of counters at the end of such period indicates the sum of the heterodyne frequency and the beat frequency; i.e. the input signal frequency. Switch 2C may be replaced by a cold cathode discharge tube switching circuit as set forth in Specification 779,233.

Title: Anthraquinone vat dyestuffs and process for their manufacture
IPC: C09B1/42
Filed: 1960-03-24
Abstract: The invention comprises 1 : 4-di(aroylamino)-anthraquinone dyestuffs having at least one aroyl residue substituted by a dialkylsulphonamide group, in which the alkyl groups may be bound together directly or through a hetero atom so as to form a heterocyclic ring or may have a hydroxy group which may be esterified by a carboxylic acid, there being present in the dyestuff molecule at least one hydroxyl group bound directly or through a bridge to an aroyl residue and being free or esterified by a carboxylic acid. Bridges specified are, besides the dialkyl sulphonamide radical, methylene, ethylenoxy and ethylenethio linkages.  The anthraquinone nucleus and the aroyl group may be further substituted.  The dyes are made by heating a 1-amino-4-aroylaminoanthraquinone with an acylating agent, the reactants being chosen so that at least one of the aroyl residues contains a dialkylsulphonamide group or a sulphonic acid halide group, in the latter case the product being reacted with an appropriate amine, and so that the dyestuff obtained contains at least one free or esterified hydroxyl group linked directly or indirectly to an aroyl group.  Examples are given.  The dyestuffs dye cellulose fibres such as cotton, linen, viscose rayon and staple fibres of regenerated cellulose pink to blue-red shades from a vat and may be used as pigments.

The pontoons A, A which may be constructed like the floats of a hydroplane, have fuel tanks, water tanks, buoyancy compartments, and crawling ways. Scoops D permit the picking up of water ballast by driving the airship along the surface of the water. The quantity of water ballast may be controlled by a system similar to that in use on submarines. Means are provided for pumping water or fuel from one pontoon to another or to comparments in the hull. Auxiliary propelling machinery may be fitted to the pontoons. The pontoons are spaced apart as widely as possible and are watertight so that when completely immersed they may maintain the hull and coaches E clear of the water. The coaches E, E may be wholly within or wholly without the hull or, as shown, attached to the frame members G, H, Fig. 6, which are strengthened at points of attachment by girders I. The pontoons are attached to the coaches by streamlined struts F which may be hollow to form passageways or to allow for the circulation of hot gases to prevent freezing of the ballast water. The bottom fin may be made to serve as a float. A control car may be placed in dront of one of the coaches E which are connected by passages E'. A main compartment or driving loom E<2> is situated centrally. The propelling machinery may be arranged in or aft of the fins. A fin or fin extension in proximity to the main fins may be adapted to carry engines brought into operation when the ship is loading or leaving the surface of the water. Specifications 309,960 and 310,104 are referred to. The airship may be moored by a sea anchor or drogue or to a mast.
