Title: Construction of photoelastic elements
IPC: G01B11/16
Filed: 1958-09-12
Abstract: A method of producing a photo-elastic element comprises preparing a flat element from a settable photo-elastic composition, limiting its setting to a degree in which it is in a plastic state and is both self-supporting and shapeable, shaping it to a desired configuration, and then allowing the composition to set.  A varnish composition, for bonding to an element the strain in which it is to be investigated, is heated for 50 minutes at 50 DEG C. and then spread upon the silicone-coated surface of a suitable flat table within a frame of suitable shape.  At the end of that period the composition is plastic and may be removed from its table and applied to the article to be tested.  If the article is a shaft, it is first coated with a suitable adhesive and the plastic strip wound around the shaft.  The assembly then stands for 24 hours at an ordinary temperature to polymerize before use. Various agents such as plasticizers and/or hardening agents may be added to the composition prior to processing.

Title: Semi-conductor Device
Inventor: SVEDBERG PER
IPC: H01L21/00
Filed: 1967-06-27
Abstract: 1,188,688. Semi-conductor devices. ALLMANNA SVENSKA ELEKTRISKA A.B. 27 June, 1967 [28 June, 1966], No. 29552/67. Heading H1K. The PN junction 1 between regions 3 and 8 of a semi-conductor body is formed by diffusion of suitable impurity into a plane surface 2 of the body under such conditions that the angle α between the junction 1 and the surface 2 is less than 45 degrees and preferably within the range 1 to 10 degrees. The junction may be the sole junction of a diode or, as shown, the centre junction of a PNPN thyristor. To achieve the required value for the angle α, the surface 2 is covered before diffusion with a layer of a substance in which the diffusion rate is at most of the same order as the rate of diffusion in the semi-conductor, e.g. in the case of silicon as semi-conductor a layer of silicon dioxide or nitride or carbide. This layer is thin or non-existent at the centre of the surface 2 and of progressively increasing thickness towards the edge. When impurity is diffused through this layer into the semi-conductor. the depth of penetration into the latter is of gradually diminishing extent with increasing distance from the centre, thus providing the required tapering shape for the junction edge. In a preferred process (Figs. 3a to 3c, not shown) the retarding layer (4) is of SiO 2  and, before diffusion, both this layer and the surfaces of the semi-conductor body not covered by the layer are covered with polycrystalline silicon (5). The latter acts as a barrier between the SiO 2  and a subsequently deposited layer (6) of dopant, to prevent the SiO 2  from dissolving in the dopant layer.

Title: Improvements in or relating to mechanical scanning devices for television systems
IPC: H04N3/04
Filed: 1936-11-03
Abstract: 481,621. Television. ARATHOON, J. G. S. Nov. 3,1936, No. 29917. [Class 40 (iii)] A scanning disc rotates in a cavity between rotating flanged tubular members for radial or spiral scanning. The tubular members 2, 6, Fig. I, rotating in bearings 11, 12 have flanges 3, 5 between which the scanning disc 7 revolves on spindle 8. As the flanged member is turned the pinion 17 on spindle 8 rolls around a fixed circular rack 16 so causing rotation of the disc. A mask 22 has in it a tapering radial slot 23, Fig. 2, which is uncovered by holes in disc 7. The area is therefore scanned in a number of sectors of shape corresponding to slot 23. In a modification the rack and pinion driving the disc are mounted within the space between the flanges. For spiral scanning the disc 7 rotates at a speed much less than that of the tubular members. For this a countershaft 32, Fig. 4, is driven by a skew gear 30 from fixed rack 26 and in turn drives disc 7 through a worm 31. The mechanism may be driven by incorporating a synchronous motor in its construction. Thus 18, Fig. 1, represents the rotor and the supporting pedestal 20 is extended to form the stator. The flanges may be used as the rotor, Fig. 6 (not shown). Specification 468,294 is referred to.

Title: Activation of peat
IPC: C01B31/12
Filed: 1948-11-18
Abstract: Sugar solutions are deproteinized and decolourized by treating with peat which has been activated by the precipitation thereon of a water-insoluble zinc salt.  The peat is first caused to absorb a soluble sodium salt which will react with an aqueous solution of a zinc salt to produce a voluminous precipitate.  Suitable sodium salts are the stannate, silicate, phosphostannate, phosphomolybdate, phosphostungstate, phosphosilicate, or aluminate, while the zinc salt may be the sulphate or chloride. The peat is preferably boiled for a short time with a dilute solution of the sodium salt, and the zinc salt in dilute solution is then added, the mixtures being boiled for a short time to ensure complete reaction.  The zinc salt may be acidified to precipitate any peat dissolved in the sodium salt.  The peat is then washed until pH of the washings rises to 6.8-7.ALSO:Coloured solutions, e.g. litmus, are decolourized by treating with peat which has been activated by the precipitation thereon of a water-insoluble zinc salt.

A game apparatus comprises a base plate i having a smooth upper surface 2, at least one pushing member 3 slidable on the base plate consisting completely or partially of ferromagnetic or permanent magnetic material, at least one rolling or sliding projectile 7 of ferromagnetic material and at least one handguided, rectilinear permanent magnet 5 which can be set up perpendicularly to the plate, the polar axis a of the permanent magnet being parallel with the polar axis b of the permanent magnetic pushing member. As shown the magnetic 5 housed in the hand element 16 is set up on a transparent cover plate 15 at any desired spot 16' in the area of the projectile 7 (or 8, 9) and, together with the projectile 7 attracted thereto, is then brought into the position 16 spaced from the pushing member 3, and together with the projectile 7 is then slowly moved in direction A toward the pushing member 3, the magnetic poles of which are N and S. At a predetermined distance, which distance depends on the strength of the magnetic force of the permanent magnet 5, the pushing member 3 is magnetically attracted and moved in direction B whereby the speed of the pushing member 3 increases. The pushing member 3 hits the projectile 7 with a certain kinetic energy and the projectile is shot away in direction B. To increase the energy of the impact, a pushing member 3 is used which has a weight several times larger than the projectile weight. It is possible with the above-described method to direct the projectile in a certain direction, in this case direction B, to any desired target 17 which can thus be shot or moves into a certain field 18 which, for example, can be football goal. The target member 17, representing the ball, can on the other hand be shot back or moved into the opposing field 19 by the opponent in the above-described manner by means of a second pushing member 3a and a projectile 7. The apparatus can also be constructed as a hunting game, the pushing members 3, 3a each being the hunter and one or several target members 17 being the rabbit or the like which is being shot by the balls 7. The members 17 can also be arranged as an obstacle for a projectile 7 by placing the obstacle, for example as a fullback in a football field, in the fullback area as indicated at 20. The obstacles are preferably made of ferromagnetic or permanent magnetic material so that they can be moved by means of a permanent magnet 5, 16. A slab of plastic or the like is provided underneath the base plate 1 to reinforce same and a closed bottom 24 and a plurality of rectangularly intersecting ribs 25, 26 which form upwardly open compartments. Other modifications are also described.
