Abstract: 1,243,131. Photo-copying apparatus. INTERNATIONAL COMPUTERS Ltd. April 20, 1970 [June 3, 1969], No.28020/69. Heading G2A. A step and repeat printer has an exposing head (1) Fig. 1 (not shown) movable in two mutually perpendicular directions in a plane parallel to a flat bed (3) on which material to be exposed is placed and, mounted on the head (1), a glass ' carrier plate 25 for a master 35 to be repeatedly copied, the carrier being movable in a direction perpendicular to the flat bed (3) between a first position, in which the master is positioned closely adjacent a portion of the material to be exposed prior to an exposure being made with a lamp 16, and a second position, in which the master is spaced from the bed (3) thus allowing the head (1) to be moved into alignment with another portion of the material to be exposed. A chamber 10 of the head (1) contains an apertured plate 29 having U-section channels 30 provided on both its faces. The plate 29 has pillars 28 depending therefrom, the pillars 28 carrying a plate 27 from which an end cap 22, carrying the glass plate 25, is suspended by a spring linkage 26. Flexible inflatable rings 31 of rubber tubing are provided in the channels 30. When the lower ring 31 is inflated, the plate 29 and hence the master 35 are raised, enabling the head (1) to be correctly positioned. Then the lower ring 31 is deflated and the plate 29 falls by gravity, thus bringing the master 35 into contact with material to be exposed. The spring linkage 26 is desirably flexed by the weight of the plates 29, 27 and of the pillars 28 to give sufficient contact pressure, but if the weight is not sufficient, then the upper tubular ring 31 may be inflated to press the plate 29 down. The source 16 may be of visible, ultraviolet, or infrared radiation.

A game dealing with word problems is played on a board a having 26 spaces b which bear each a letter of the complete alphabet and one of the numbers 1 to 26 but the lettered spaces are not numbered in alphabetical order. There are also a set of counters c numbered in sequence, a book or card setting out numbered problems, and a set of numbered cards for selecting the problems. Parts 'd of the board or separate cards denote the type of problem, e.g. opposites or anagrams. In play, a problem selecting card is drawn by chance, and the player looks up the appropriate problem in the book or card. The problem first gives a series of figures which prescribes the number of counters. c (say 4 numbered 1 to 4) and the order in which they are to be laid in a line (say 4, 1, 3, 2). The problem then gives a set of say four numbers from 1 to 26 giving the board spaces in which the counters are to be placed in the order in which they have been laid in the line. Then the letters of the spaces containing the counters are read off in the sequence of the numbers on the counters and this gives a word. The problem then gives a number instructing which space d is to be used, i.e. which type of problem is to be applied to the word, a number from 1 to 26 may also be given to identify the first letter of the solution, i.e. to give a clue. The problem book also gives instructions for setting up the solution on the board in a like manner to that used for setting up the problem word.

Patent GB-357778-A (GB)
Title: Process for the production of active carbon and gases containing free hydrogen
IPC: C01B32/336
Filed: 1930-09-24
Abstract: In a process for the production of active carbon and combustible gases containing free hydrogen, commercially cheap materials are employed which are rich in ash or ash-forming constituents, e.g. low-temperature coke or brown coal, the activation temperature being between 400 DEG  and 700 DEG  C., preferably 500 DEG  to 600 DEG  C., and the gases employed being mixtures of steam with gas containing free oxygen in amount up to 6 per cent of the mixture.  The temperature of the activating gas should not exceed 250 DEG  C., preferably 120 DEG  to 200 DEG  C., and the activating temperature is maintained by the heat evolved during the reaction, external heating being applied only to prevent losses from the reaction chamber or to bring the temperature in certain zones up to the required point.  For activation, carbon dioxide may be employed in addition to steam and air or oxygen, and the activation may be carried out at atmospheric, increased or reduced pressure.  In operation, the materials to be treated may be stationary or move in counter-current to the activating gases and activation takes place in a zone which, in the case of stationary material, moves forward throughout the mass.  The material to be treated is brought to the desired activation temperature over a grate, or if moving, at a certain point, by a blast of hot gas containing oxygen, preferably air.  In an example, air at 150 DEG  C. was blown for an hour through a layer of low-temperature coke and then a gaseous mixture at 120 DEG  C. containing 80 per cent of steam and 20 of air was admitted, the conditions being controlled to give an activating temperature of 500 DEG  C.  The loss through burning amounted to 18 per cent of the original material and a waste gas containing 21 per cent of hydrogen was obtained.  In a second example, a mixture of 95 per cent of steam and 5 of air was used as the activating gas with an activating temperature of 600 DEG  C., a waste gas containing 30 per cent of hydrogen being obtained. To avoid loss of heat, when using semi-coke, the converter for the coke may be in direct communication with the activating chambr and the coke may be brought to the desired size before activation. Suitable after-treatment, such as screening, washing with water or chemicals or supplementary activation, may be applied, and the waste gases may be used for heating purposes. Specification 313,154, [Class 90, Non-metallic elements], is referred to.

Title: Improvements in or relating to apparatus for manufacturing laminated bodies
IPC: H02K15/02
Filed: 1962-07-25
Abstract: 1,010,221. Riveting; producing dynamo-electric machines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 25, 1962 [July 28, 1961], No. 28580/62. Heading B3A and B3U. Apparatus for manufacturing laminated bodies, suitable for the stators or rotors of electric motors, removes a quantity of plates from a stock, aligns holes in the plates, inserts eyelets in the holes, and compresses and fastens the plates together by turning over the ends of the eyelets. A reciprocating slide 6 shifts a number of plates 2, having the shape of Fig. 2, to the right to position 39, a spring- loaded arm 9 allowing for slight variations in the thickness of the pack. During this movement a head 16, attached to the slide 6, rotates a lever 18 to which is attached by a rod 22 a block 19, so that the block moves to the left. Eyelets 21 from tubes 25 fed from a vibratory device 24 fall into apertures in the block. On the return movement of the slide 6 the block 19 moves back under the action of a spring 17a to its original position as illustrated, and the head 11 of a lever 12 on the slide shifts the head 30 of a rod 29 to the left so that the locating pins 26, connected to a lever pivoted at 28a, are moved into the apertures of the plates. A press 32 then moves downwards to turn over the ends of the eyelets in a stack of plates at 40 while at the same time eyelets are pushed by rods 33 into the stack at 39 and the pin 26 thereby pushed clear. The stack at 40 rests on a spring table 36 so that the lower end of the eyelets are deformed against dies 37. During the next stroke of the ram 6 the stack of plates at 39 is shifted to the position 40. The plates are compressed before eyeletting by a spring-loaded plunger 34.

Title: Improvements in or relating to an acoustic chamber for modifying the characteristicsof material
IPC: B01J19/10
Filed: 1946-09-25
Abstract: <PICT:0636183/III/1> An acoustic chamber for modifying the characteristics of material comprises walls forming a chamber, an annular inlet 76 in the top of the chamber, and a valve-controlled means 78 for admitting the material to said inlet to form an annular curtain of material dropping through said chamber, and means 30 for introducing compression waves to said chamber for action upon the falling material.  The chamber is of toroidal form, whereby the waves are reflected back and forth many times through the curtain of material.  Treated material passes through an annular outlet 100 and collects in a trough 102, whence it passes to a sump 104.  Air admitted simultaneously with the waves passes out through passages 36 and do not enter the chamber proper, thus preventing the possible disruption of the curtain.  Byepass tubes 150 relieve any pressure set up in the chamber after it has been in operation for some time. The system may be operated at any pressure, and in an atmosphere of hydrogen, air or chlorine.  In the latter case, liquids may be chlorinated.  The inlet may be at the bottom for smoke or gases or at the side, or the inlet may be an annular series of spray nozzles for introducing solids to be treated.  Oil and water may be emulsified. In the modification shown in Fig. 5, air is admitted through a conduit 260 and strikes against a knife-edge 214, whereby air vibrates in the chamber 210 and the vibration frequency is a function of the position of tube 283 and the reciprocating sleeve 280, which is driven by a motor 290 via an eccentric 286 and a shaft 284 of variable length. <PICT:0636183/III/2>

Title: Aircraft with variable sweep wings
Inventor: WATSON HENRY ROMAINE
IPC: B64C3/40
Filed: 1951-12-07
Abstract: 712,023. Controlling swept-wing aircraft. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G. Dec. 4, 1952 [Dec, 7, 1951], No. 28691/51. Class 4 In an aircraft in which the wings are angularly adjustable during flight for sweep, the wing roots have arcuate tracks coacting with respective arcuate guides within and fast with the fuselage,' whereby each wing can be swung about a substantially vertical axis which is spaced outwardly of the fuselage, on the same side as the wing, and in such a position that there will be no change in the stability and trim of the aircraft during the angular adjustment of the wings, there being a reversible power-operated means, acting substantially tangentially of the tracks, for adjusting the sweep of both wings simultaneously. Each wing, of which the top surface 22 and leading and trailing edges 24, 26 are shown in figure 1 in relation to the fuselage 20, is closed at its root end by a bulkhead 34 formed on its top and bottom edges with two tracks 36 which are arcuate about a vertical axis X. Each pair of upper and lower tracks cooperate with channel guides 50, 52 rigidly attached to a beam 54 within the fuselage. The beams support a fore and aft bulkhead 56 to each side of which is attached a guideway 67 for a nut 64 mounted on a screwed shaft 62 rotated by an hydraulic motor 69. The nut is pivotally attached to the inner end of a rod 66 attached at its outer end 68 to the bulkhead 34 in the wing root. Should excessive wing deflection during an adjusting movement cause the tracks 36 to bind in the guides 50, 52 a relief mechanism shown in figure 5 is brought into automatic operation. In this arrangement, the bulkhead 34 is omitted, the tracks and guides being shown at 36a, 50a and a spanwise cantilever beam 72 is positioned within the root end of the wing fast with the fuselage with its outer end 74 resting on a piston movable within a cylinder 82. If, during a sweep, the hydraulic circuit to the motor 69 becomes overloaded an automatic cut-off valve diverts the liquid to the cylinder 82 which reacts against the piston and the beam 72 to reduce the wing deflection and remove the binding action between the tracks and guides. To prevent downward deflection of the wing during this operation from overloading the tracks in the opposite sense, an arm 94, pivoted at 108 to the beam 72 and in contact at its outer end 96 with the upper surface 22, of the wing is arranged to operate a cut-off valve 92 located on the sweep axis X.
