Abstract: 902,699. Supplying current to electric cranes. FAHRLEITUNGSBAU G.m.b.H. June 17, 1960 [June 19, 1959], No. 21468/60. Class 104 (3). In a feeder device for supplying current to electrically - operated cranes the feeder 1 has contacts 3 for co-operating with collector bars 6 mounted on a crane and is raised or lowered into or from an inoperative to an operative position above the ground by a crank mechanism 12, 13 operatedby racks 9, mounted on the crane, engaging pinions 10 connected through gears 11 or a chain-and-sprockets to the crank mechanism 12, 13. The feeder 1 is provided with contact blades 5 which engage power supply contacts 2 when the feeder 1 is in the raised position. A number of feeders 1 may be spaced along the path of the crane which has at its front and rear ends racks 9 so disposed that as the collector bars 6 move out of engagement with a feeder 1 at its rear end the feeder is lower and the feeder 1 in front of the crane is raised.

Class 29 In a continuous - cycle absorption system the generator tube 29 is heated externally at 11 and welded near its lower end to a pipe 20 for conducting weak liquor from the generator to the absorber, and contains the pump pipe 19 which is of L-shape with its longer limb resting against the wall of the generator tube and its shorter limb press fitted over or into a supply tube 18 for strong liquor mounted within the pipe 20. The pump pipe 19 is first inserted into the open upper end of the generator so that its shorter limb is opposite a hole in the lower part of the generator table, the supply tube 18 is welded to the pipe 20 at 30 and this assembly introduced into the hole in the generator tube, the end of the supply tube 18 being pushed over the pump pipe, and the pipe 20 is then welded at 31. The upper end of the pump pipe 19 is located in position by a constrictor tube 33 welded in the generator tube, and a condenser tube 12 is welded to the upper end of the generator. The pump pipe has a number of metal ferrules 39 or an internally screw-threaded sleeve inserted in it to facilitate the formation of bubbles, or a screw thread may be cut in the pipe for this purpose. Fig. 6 shows a modification in which two pump pipes 19a, 19b are used, fitted at their lower end into a header 42 having an extension 43 into which the supply tube 18 is pushed. The concentration of the ammonia is preferably 45 per cent of ammonia by weight so that there is minimum decomposition of ammonium hydroxide and little heat liberated in the absorber.

The compounds are obtained by condensing the appropriate substituted or unsubstituted 2-methylpyrimidine with 5-nitrofurfural at room temperature or, preferably, at 50 DEG  to 150 DEG  C.  The 2-[2-(5-nitro - 2 - furyl) - vinyl] - 4 - aminopyrimidine may also be obtained by hydrolysing 2-[2-(5-nitro - 2 - furyl) - vinyl] - 4 - acylaminopyrimidines, e.g. by heating with mineral acids for about one hour.  The 2 - [2 - (5 - nitro - 2-furyl) - vinyl] - 4 - hydroxypyrimidine may also be obtained by hydrolysing 2-[2-(5-nitro-2-furyl)-4-aminopyrimidine, e.g. by heating with mineral acids for about 4 hours.  The compounds are stated to possess antibacterial, antimycotic and antitrichonomal activity.
Patent GB-830348-A (GB)
Title: Improvements in and relating to the dyeing of fibrous materials or films
IPC: D06P5/20
Filed: 1956-07-12
Abstract: Fibrous materials, such as textiles, paper or leather, or films, are coloured by depositing thereon in a high vacuum the vapours of dyestuffs which vaporize or sublime without decomposition.  Improved effects may be obtained by pretreating the surface of the fibrous material with an adhesively acting substance such as a thermoplastic synthetic resin.  The fastness to rubbing of the colorations may be improved by subsequently applying a synthetic resin or varnish. Patterned effects may be obtained by employing stencils.  In the case of fabrics, leather or paper, both surfaces may be coloured by the same or different dyestuffs.  An example describes the colouring of a polyamide fabric.  Specification 349,683 is referred to.

Title: Collar protecting hood and spray dampener for ironing presses
IPC: D06F87/00
Filed: 1943-12-28
Abstract: 575,692. Ironing and pressing machines. WILLIAMS, W. P., (American Laundry Machinery Co.). Dec. 28, 1943, No. 21737. [Class 138 (ii)] Means is provided for protecting the collar portion of a partially finished shirt while damping the front portion before ironing. As applied to a turret press a hood 18, closed at sides and top, is pivoted at 23 to a bracket 22 fixed to the machine and normally held up by a pair of springs 24. A fluid-pressure actuated ram 25 has the fixed member attached to the bracket 22 and the movable member to the hood and is connected by a pipe 28 to a normally closed valve 27 with an exhaust port 29 and pressure supply pipe 26. The operator arranges a shirt on the board 11 of the machine in the dressing position where the board is tilted at about 45‹. draping the collar about the block 19 and securing it by a clamp 20. The front and tails of the shirt are draped downwardly on the board, and secured by a clamp 21. The spray gun is then lifted from its supporting pin 34a on a rack 32 pivoted at 32b which is then raised by a spring 33 to raise a lever 31 to engage the stem 30 and open the valve 27 admitting air to the part 25 which thereupon lowers the hood 18 to cover the collar 19 before the operator can manipulate gun to position and spray the shirt front. To prevent actual delivery of liquid from the spray gun except when the hood is fully lowered to protecting position, a tongue 38 at the rear of the hood is provided to open in that position a valve 39a and admit air to a diaphragm 42 which opens a valve 43 to admit water from a supply pipe 44 to the flexible feed pipe 35 of the spray gun. Water falling on the hood 18 is guided by bearings 18b to a lip 18a so as fall into a trough 22a for delivery by a pipe 37 to the heated steam chest 12 where it is evaporated. When the shirt is thus prepared, the operator depresses a pivot to swing the board round and bring it horizontal under the press head 12, the finished shirt coming into the tilted position for removal, the tilting being effeced by a ram 17, Fig. 3.

Abstract: 1357501 Cameras POLAROID CORP 10 May 1972 [10 May 1971] 21887/72 Heading G2A A camera has a member 62 which is movable to advance an exposed film unit 39 to rollers 40, 42 and a latch 140 which prevents member 62 from returning to its initial position until rollers 40, 42 have ejected the unit. This stops member 62 from advancing unexposed film units. As shown, on shutter release a motor 38 drives a gear train 44 to raise a reflex mirror 46. After exposure the motor 38 is energized again and gear train 44 moves member 62 via a pin 130 on gear 102 so that an arm 88 attached to member 62 advances the exposed unit to rollers 40, 42 and member 62 is held by latch 140. By the time rollers 40, 42 have ejected the unit, a cam 128 on gear 110 engages an arm 150 to release latch 140 and engages a cam 124 to cause ram 160 to return mirror 46 to its viewing position.

[Class 4.] The spar of a single-spar wing is so connected to one end of a strut, which is connected at its other end to an adjacent wing or other part of the aircraft, as to resist twisting of the spar. Fig. 3 shows a biplane structure wherein single spars 13, 14 are connected each at two points fore and aft to a compound strut 22 extending between the two wings. Each wing may have tension members at the leading and trailing edges braced to the spar by ribs and cross bracing so that fore and aft movements of the ends of the strut 22 are resisted. Near the centre of the machine struts extend from the spars to widely spaced points on the fuselage. Each strut comprises channel members 23, Fig. 5, connected by bracing 24 and connected to the spar by pivots 35, 36 spaced fore and aft. The strut carries formers at intervals to support a fairing. The interplane struts and fuselage may be braced together by wires, or struts in zig-zag formation may be used. A monoplane is described in which the spar is braced at two points fore and aft by two struts converging to a single point on the fuselage. These struts may be separate or braced together.
