Title: Improvements in folding cardboard and like boxes
IPC: B65D5/498
Filed: 1946-07-31
Abstract: 625,044. Boxes. SMITH, W. H. July 31, 1946, Nos. 22798/46, 35080/46 and 9420/47. [Class 18] A folding cardboard or like box has a partition 16, which prevents the walls from bulging, secured to two opposite walls by pliable metal tabs 11. The walls 1 fold about creases 3 when the box is collapsed. In one construction vertical "T" members 4, stitched to the walls 1 have one or two tabs 11 secured by a rivet 10. The top 7 of the partition 16 is folded over and a slot 8 extends along the fold line leaving solid parts 9 at each end. Two lids 13 hinged to end walls 2 have flaps 14 which fit inside the body and tuck into the slot 8. Alternatively, a separate lid with side flaps fitting outside the body of the box may be secured. by tabs 35 passing through slots 34. In a modification, tabs secured to the side walls and passing through a slot in the lid may be bent down over the side walls of both the lid and of the body. In the construction shown in Fig. 6, the tabs 33 are folded up to pass through a slot in the wall 1 and are then opened out to reinforce and secure the walls. The top edges 40 of the walls 1, 2 may be folded inwardly and downwardly. The walls 1 may have extensions 28 which overlap and strengthen the walls 2. The pliable tabs may consist of card or paper reinforced with metal strip or wire. Wire alone may be used, in which case the wire passes through holes in the lid or wall. Reinforcing battens 17 may be fitted to the bottom to co-operate with rigid posts 15 in stacking. The lid may have hinged cutouts to facilitate filling the box. The box may be treated inside and outside with a waterproofing substance. Specification 593,373 is referred to.

Title: Improvements in or relating to x-ray sensitive elements
Inventor: KELLER MANFRED
IPC: G01T1/26
Filed: 1953-08-20
Abstract: 748,302. Photo-electric cells. ZEISS IKON AKT.-GES. Aug. 20, 1953, No. 22985/53. Class 37. [Also in Group XL (a)] X-ray sensitive elements are made by evaporating selenium in vacuo on to a base plate held at below 50‹ C. to produce a completely amorphous layer, the thickness of which is that giving a maximum X-ray conductivity coefficient, i.e. between 50 and 300 Á.To reduce the electrical inertia heavy metals or heavy metal selenides are mixed with the selenium by concurrent evaporation. The proportion of heavy metals may vary from zero to the stoichiometric ratio for the corresponding selenide. The proportion of impurity may be varied through the thickness of the layer to give a surface on which the X-rays are incident rich in impurity while the other surface is of pure selenium. Preferred additives are lead selenide, silver selenide, and tellurium. In one embodiment an Se layer 2 is deposited on a glass base plate 1 between evaporated on electrodes of aluminium 3, 4 while in another an amorphous Se layer 200 Á thick is deposited on a metal plate and provided with a counter electrode layer of a material which does not react with Se and is permeable to X-rays, e.g. aluminium, nickel, graphite, carbon black or carbon. The X-ray iconoscope shown in Fig. 4 comprises a glass or aluminium bulb of mainly spherical form with a window of material more permeable to X-rays if the bulb is of glass, e.g. beryllium glass, or Lindemann glass (lithium-berylliumborate glass), and contains a screen electrode comprising an X-ray permeable plate 12, e.g. of Al sheet carrying an Se layer of the above type between 50 and 300 Á thick, and a mosaic plate may cover the Se layer. Such an element may also be used in a television scanning tube with an electron objective of the orthicon type.

Abstract: 1513966 Electromagnetic relays MATSUSHITA ELECTRIC WORKS LTD and SDS-ELEKTRO GmbH 23 May 1975 [30 Dec 1974] 22988/75 Heading H1N An electromagnetic relay comprises an armature in the form of a bar having both ends free arranged within a protective tube 2 forming part of a coil bobbin, terminals embedded in the bobbin, four pole shoes 6, 6<1>, 7, 7<1> embedded in the bobbin and permanent magnets 13 in chambers in flanges of the bobbin, the permanent magnets and pole shoes being so arranged as to be symmetrically disposed relative to the longitudinal axis 64 of the bobbin and relative to an axis perpendicular to this longitudinal axis and passing through the centre point of the coil bobbin. The armature serves at its free ends as movable contacts and parts of the pole shoes serve as the fixed contacts with which they cooperate. The armature may be floating, or held by springs, Figs. 8 and 9, not shown, or pivoted, Fig. 10, not shown, or held by knife edges, Fig. 11, not shown, all such holding arrangements being central. A plurality of armatures may be present in the relay which may also have more than one coil, Figs. 14 and 15, not shown. The tube 2 containing the armature and contacts may be hermetically sealed and filled with a protective gas. Its walls may be coated with a getter material or the magnets may be made of activated barium ferrite and rare earths to act as a getter. Hermetic sealing is effected by ultrasonic welding and potting the relay with a compound. A can 57 of ferromagnetic material screens and protects the relay, the permanent magnets being spaced from this can. The coil bobbin may be made of two interengageable halves which are welded together during manufacture and in this case one half has grooves cooperating with ribs formed in the other half: to ensure at assembly the correct width between fixed contacts in respective halves of the bobbin assembly gauges are used. The armature may have a rectangular cross-section or a circular or barrel-shaped cross section, Figs. 4, 5, not shown, and it may have a rest position against the pole faces to one and the same side of the longitudinal axis or may have a diagonal rest position against one pole face on either side of the longitudinal axis, or it may have a central neutral rest position when it is not in contact with any pole face. In the latter case centring springs are provided, Fig. 12, not shown.

Tooth errors in a test-gear 20, driven by a rotating master gear 18 mounted on one arm 26 of a two-armed lever 22, pivoted at 28, are indicated on an indicator 36 Fig. 3 as the relative movement, caused by the sudden deflections of arm 26 when faulty teeth are enmeshed, between (see Fig. 3) a light carrier 64 and a heavy weight 70 both suspended from a bracket 96 and engaged, respectively, by an abutment 34 of the arm 26 and the actuating rod 66 of the indicator 36. During the time of traverse of faulty teeth the high inertia of the weight 70 prevents any appreciable movement thereof thus causing relative movement between it and the carrier 64. At the same time, any eccentricity of the gear 20 will impart slower pivotal motion to the lever 22 (which will not produce relative movement of the carrier 64 and weight 70) and this will be indicated on a dial gauge 74. The latter is carried on a slide 72. An end-piece 30 of the arm 24 of the lever 22 carries pins 44, 42 engaging respectively, with the actuating rod 48 of the gauge 74 and a pin 46 having a lost-motion connection via a flange 78 and a notch 82 with the slide 72. The latter is depressed, as the test-gear rotates, to a lowermost position, depending on the size of gear and the eccentricity, via the lost motion connection. Thereafter further rotation of the test-gear will not move the slide 72: reciprocating movement of the lever-end 30 will reciprocate the pin 46 freely within the lost-motion range, while the actuating rod 48 will reciprocate to give a fluctuating reading on the gauge dial corresponding to the gear eccentricity.
