Title: Parachute
IPC: B64D17/14
Filed: 1961-03-27
Abstract: 909,631. Parachutes. LEMOIGNE, P. M. March 27, 1961 [April 7, 1960], No. 11161/61. Class 4. A parachute comprises a plurality of nozzle means formed through the canopy to direct air from the lower to the upper surface of the canopy along flowpaths having a horizontal component in a common general direction, to impart an opposite horizontal component of motion to the canopy during descent, Fig. 4 shows the gores and shroud lines of a flat circular parachute laid out radially. Of the gores, those between shroud lines j and o are formed with channels 201, 202 through which air passes from the lower to the upper side of the canopy, flowing radially outwards, as shown by airflow lines 22 in the vertical section of Fig. 6. The gores between shroud lines v and c have similar channels 203, 204 through which air passes from the lower to the upper side of the canopy, flowing radially inwards. These airflows cause a horizontal motion of the parachute in the direction of arrow 70, the horizontal velocity being controllable by the user by cords (not shown) attached to the fabric of the channels to vary their cross-sections. The gores between shroud lines d and h, and q and u, have channels such as 84, 85, discharging air in a circumferential direction to assist horizontal motion, and can be opened differentially on opposite sides of the canopy to control the canopy in azimuth. The remaining gores have slits 205 with reinforced edges, which open on deployment to reduce the initial shock, and can be closed manually afterwards to increase drag. Stabilizing panels 61-66 are disposed in two opposed groups, each panel being attached along its edges to the adjacent shroud lines. The upper edge 99 of each panel is shorter than and not attached to the opposed edge 100 of the corresponding gore, so that during descent, air can flow through the aperture which is formed. Triangular panels 80, 81, 86 and 87 flank the main panels. The horizontal component of drag of the canopy is reduced by omitting part of the front portion of the canopy, see also Fig. 7, the cut-out being framed by inflatable tubular frame elements 93-96 reinforced by tapes 97 and 102. The stabilizing panels may be in two diametrically opposed groups, or if the airflow channels described above are not provided, may extend all round the canopy. The canopy may be triangular, rectangular, or trapezoidal in plan, and may be shaped by interior rigging lines and plastic or light alloy stiffeners, to have the contour of a highly cambered wing. The rigging lines may have suitable fabric sheaths 98 to protect the stabilizer panels during deployment.

Abstract: 858,008. Feeding articles. FOOD MACHINERY & CHEMICAL CORPORATION. Feb. 18, 1957 [April 30, 1956], No. 11171/60. Divided out of 858,007. Class 117 [Also in Group XVII] A machine in which collapsed cartons are erected (see Group XVII) preparatory to filling with articles such as pies, comprises a carton feeding magazine 140, Fig. 7, a conveyer 130 below the magazine, and a plurality of spaced blocks 133 on the conveyer, each block having a shoulder 139 on its upper surface for engaging and removing a collapsed carton from the bottom of the magazine. The magazine has a fixed gate comprising two blocks 173 adjustably spaced from the magazine base 158 so that only one carton at a time can pass therebetween. A cam operated member 180 closes the gate until the trailing edge of a carton is engaged by a shoulder 139. The gate is then opened whilst the carton passes therethrough. The feeding of the cartons can be temporarily halted if sensing means in the machine indicates that a pie is not available for any particular carton in the magazine. A solenoid 318 is then actuated at an appropriate instant to operate a pair of arms 325 carrying members which raise the stack of cartons in the magazine 140 so that the lowermost carton is not removed by the shoulder 139 on the block 133 corresponding to a point in the machine where a pie is absent.

Title: Improvements in or relating to water treating compositions
IPC: C02F5/10

Abstract: A composition for treating water comprises a substantially homogenous mixture of (a) 80-96 per cent by weight of a water-soluble molecularly-dehydrated alkali metal phosphate having a ratio of alkali metal oxide to P2O5 of from 1.0 to 1.3, (b) 19.98-2 per cent by weight of an alkali metal carbonate, bicarbonate or percarbonate or a mixture thereof and (c) 0.02 to 2 per cent by weight of an unsubstituted aliphatic carboxylic acid containing from 6 to 10 carbon atoms for each polar group, the polar group including carboxylic acid groups and unsaturated double bonds.  The percentage of phosphate in the composition is preferably not less than 88 per cent and the percentage of carbonate or the like is preferably from 10 to 3.98 per cent. Examples of acids are caproic, isocaproic, heptylic, caprylic, pelargonic, capric and oleic, of which oleic is preferred.  In one example 1 per cent by weight of n-heptylic acid is added to a mixture of a commercial sodium hexametaphosphate product and 6 per cent. of sodium carbonate.  In a second example the 1 per cent of n-heptylic acid is replaced by 0.2 per cent of oleic acid. In a third-example 0.5 per cent of oleic acid is added to a mixture of sodium septaphosphate (Na9P7O22) and 6 per cent of sodium carbonate.  When the composition contains an alkali metal carbonate, bicarbonate or a mixture thereof the ingredients of the composition must be so proportioned as to yield a pH in 1 per cent aqueous solution of 6.7 to 8.0, preferably 7.8. Additional alkalinity-adjusting agents such as caustic soda, sodium sulphate, bisulphate or bisulphite, sodium metasilicate, trisodium orthophosphates, sodium pyrophosphates, sodium polyphosphates having a Na2O/P2O5 molecular ratio above 1.3, and mixtures of these, and also the corresponding potassium salts may be added to the composition. The particle size of the main phosphate part of the composition should be not coarser than 50 (preferably 100) mesh.

A wagon or like loader consists of a frame comprising two curved rails adapted to rest in a, slanting state with their lower end adjacent the ground and their upper end supported on a platform, and an articulated carriage cunsisting of sections connected together by pivotal links being supported and guided by the rails and having a projecting bed to receive a sack or other article and being hoistable by a cable or the like to bring the sack from ground level up to the level of the platform, the carriage being adapted partly to leave the rails at the upper end and be partly projected on to the platform, whereby a hand. truck can be wheeled on to and off the carriage from and to the platform so that the sack or the like can be pulled on to the hand truck from the carriage and be conveyed to its place on the platform by the hand truck. In the embodiment shown, the loader comprises a wheeled ramp built up of rails I connected together by a. plate 4 provided with lugs 5 adapted to rest on the edge of the platform of the vehicle to be loaded. The carriage consists of three articulated sections, 35, 36, 37, the first comprising a plate 11 carried by beams 10 connecting axles having rollers 9 engaging the rails 1, the second a plate 15 carried by beams 14 connecting axles 12 having rail-engaging rollers 13 and the third an angle plate 20 supported on angle beams 19 on which are mounted axles 17 with rail-engaging rollers 18. The section 36 is suspended from the section 35 by links 16 connecting the lower axle 8 and upper axle 12, and the section 37 is suspended from the section 36 by links 34 connecting the upper axle 17 with the lower axle 12. When a sack is to be loaded on to the vehicle platform, the load-supporting bed 41 on the section 37 is brought to its lowest position and the sack transferred to it by, for example, a hand truck. The carriage is then raised by a cable 30 secured to a winding axle 24 and passing over an idle axle 31, mounted in brackets 32 on the rails 1, to a cross beam 33 on the section 37. The axle 24 is connected through spur gearing 25, 26 to an axle 23 which is rotated by a handle 27 and which is provided with a ratchet wheel which co-operates with a handoperated pawl 29 to prevent reverse rotation of the axle when desired. When the section 37 reaches the curved portion of the rails, the section 35 is projected on to the platform to enable a truck to be run on to the section 36 to receive the sack and then transfer it to its place on the platform.
