Abstract: 639,546. Toy aeroplanes. JENKINS, D V., PARSBO, E. M., and PARSBO, H. P. Jan. 30, 1947, No. 2850. [Class 4] A toy aeroplane or glider comprises a hollow fuselage and a pair of wings hinged together at their roots, the roots being shaped to enable a portion of the lower surface of the fuselage to be received between them and being provided with upward projections which, when interconnected by an elastic strand or loop or like resilient connection passing over the top of the fuselage, abut the sides of the latter and ensure that the wings are located at a predetermined dihedral angle relatively to one another, symmetrically to the fuselage. A hollow fuselage 1 is reinforced at its forward and aft ends by stiffening rings 7, 8. The ring 7 supports a plug 39 bored to receive an elastic driven propeller spindle 38, the rear end of the plug being formed into a collar 43 having opposed flat faces arranged to pass between the cross-member of an inverted U-shaped wire undercarriage 33 and a wire 36 positioned below said cross-member and hooked at its ends to retain the undercarriage frame in an extended position. When the plug 39 is rotated a quarter of a turn the wires engage the collar and retain the plug within the fuselage. The ring 8 supports an end cap 10 which carries a hook 15 for the.elastic motor 9 and is provided with a slot 14 to engage a fin 18 and a slot 12 and grooves 13 to engage a cut-out 17 in the tail-plane 16, the leading edge of which engages in slots 11 cut in the rear end of the fuselage, the assembled tail unit being retained on the fuselage by elastic bands 21 engaging a pair of hooks 20 mounted on the fin. The wings 23, 24 are shaped at their roots to rest against the corresponding fuselage walls and are connected at the leading and trailing edges by wires 26 hinged together by strands of cotton, the wings being retained in positionby an elastic band 31 engaging shaped hook-like wire projections 29 which may be constructed as shaped end ribs integrally formed with the wing roots to ensure that the wings are located at the correct dihedral angle. To ensure that the wings are set at the correct angle of incidence, the front face of the ring 7 and the rear face of the ring 8 are bevelled so that when they lie in the vertical plane, the longitudinal centre line of the fuselage is inclined upwardly from tail to nose. The aeroplane may be made from balsawood by the process described in Specification 638,350, [Group VIII]. The rings 7, 8 may be omitted and the fin may be integrally formed with the cap 10.

Title: Woven fabrics
Inventor: BLYTHE NIGEL
IPC: D03D15/56
Filed: 1965-01-22
Abstract: A fabric having 10-40% stretch in one direction, due to crimp interchange produced by heat treatment with the yarns in the other direction under tension, is woven from thermoplastic spun yarns of cellulose triacetate, nylon 6 or 66, or isotactic polypropylene.  The heat treatment is at 20-80 DEG C. below melting point for 30 secs. followed by cooling to 50-200 DEG C. below melting point before removing the tension; the fabric must not have been previously heated to within 50-120 DEG  of the melting point, and the heat treatment temperature should be at least 10 DEG  higher than any temperature previously experienced by the fabric.  To produce weftwise stretch, the fabric may be treated by hot air in a stenter which has tension bars that will withstand 40% warp stretch without bending and which has no pins or other means to restrict weftwise contraction, there being also a cold air fan to cool the fabric.

Title: Method of operating mercury cathode electrolytic cell plant
IPC: C25B1/36
Filed: 1968-01-19
Abstract: 1,203,361. Electrolysis of salt solutions in mercury cathode cells. ORONZIO DE NORA IMPIANTI ELETTROCHIMICI S.A.S. Jan.19, 1968, [Jan.27, 1967], No.3041/68. Heading C7B. In operating plant comprising flowing mercury cathode cells through each of which an electrolyzable salt solution (brine) is continuously recycled, a concentrated solution being fed to the cell and a depleted solution being withdrawn from it, in order to increase the operating efficiency by increasing the electrolyte flowrate through the cell and reducing the temperature and concentration differences between the feed and return streams without increasing the load on ancillary resaturation and purification equipment, at least one third of the depleted solution is recycled back to the cell without chemical treatment while the remainder is recycled via a resaturating and purification plant. As described the mercury circuit including a denuder of each cell is independent, but the brine, typically sodium or potassium chloride solution, may be fed from a header common to all the cells. Typically up to nine-tenths of the depleted solution may be recycled without chemical treatment. Either the whole (see Figs.1, 2 not shown) or at least a part of the resaturated salt stream is combined with the untreated stream before recycling to the cells. The combined solution stream may be introduced at one or more points intermediate the cell ends in addition to the upstream end of the cell (see Fig. 2). As shown combined solution stream is introduced at the upstream end and saturated solution is introduced at an intermediate point along the cell such as by pipe 16 and sparger 19. The cell is of the kind described in Specification 894, 769 in which graphite anodes 6 are supported by graphic rods 7 secured to a metal spider 11 secured to a beam 24 which is attached to bars 5 adjustably secured to posts 4 seating on the top flange 3 of the electrolyte trough 1. The anodes are provided with longitudinally directed slots 21 which communicate with gas escape holes 22 and baffle plates 20 are supported across the cell between groups of anodes, especially at locations where electrolyte is introduced, to effect stirring of the bath and so assist in gas removal and renewal of electrolyte between the anodes and flowing mercury cathode. The top of the cell is closed by a flexible rubber or plastics sheet through which the connections to the anode rods 7 and the electrolyte supply pipe 16 pass. A gauge 17 which may include means for automatic flowrate control and a manual valve 18 are also provided. On start-up the heat exchanger J may be operated so as to warm the brine fed to the cell while on shut-down with the arrangement shown in Fig.3 the cell is preferably fed with pure brine through the inlet end by suitable operation of valves K, L, M.

Title: A bistable circuit
IPC: H03K3/289
Filed: 1967-01-20
Abstract: 1,101,660. Transistor bistable circuits. NORTH AMERICAN AVIATION, Inc. 20 Jan., 1967 [7 June, 1966] No. 3079/67. Heading H3T A bi-stable circuit comprises two NAND gates 1, 4; a control signal connected to one input 23 of gate 1, and a control prime signal connected to one input 32 of gate 4; an input signal connected to the other input 20 of gate 1; and an inverter 7 connected to the outputs from both gates, the output from the inverter being connected back as the second input 36 to the gate 4. In operation a negative signal (logical " 1 ") at inputs 20, 23 will set the output at 13 to a " 1" level. If the control signal now changes to " 0 " and the control prime to " 1 #, the circuit remains in this state due to the " 1 " signal fed back to the other input to gate 4. The state of the circuit will change when a " 0 " is applied on input 20 during the presence of a " 1 " on input 23. In order to synchronize the switching with the control signals the circuit may be followed by a second similar circuit with the control and control prime inputs reversed, Fig. 3. The control and control prime signals for the first circuit (master) are derived from points B and A respectively of control circuit 52 and those for the second circuit (slave) are derived from points C and B. The exact phasing of these three signals is offset due to the time delays of transistors 70, 71, Fig. 5 (not shown).
