Title: Miniature single lens reflex camera
IPC: G02B5/04
Filed: 1976-06-07
Abstract: 1496853 View-finder systems ASAHI KOGAKU KOGYO KK 7 June 1976 [20 June 1975] 23412/76 Headings G2A and G2J In a single lens reflex camera the view-finder system includes a combination of a trapezoidal prism 10, a right-angled prism 11, and an equilateral prism 13, so disposed that the light path is folded several times in passing through the system to the eye-piece 14, thus enabling a more compact structure to be obtained. Further compactness, desirable in miniature cameras, is obtained by interposing a glass block 5 between the shutter 4 and the film cassette 3. This has the effect of moving the focal point of the objective lens system back from f 1  to f 2 . As shown, when mirror 6 is in the viewing position, it reflects incident light to a prism 8, after which it passes through an erecting lens 9 to the prism system 10, 11, 13. Light incident normally on prism 13 passes through the faces 10a, 10b, and is incident on prism 11 along path a. It is internally reflected from faces 11b, 11c and passes back to prism 10 along path c, through an interposed focusing plate 12. It is internally reflected from faces 10c, 10d, along path e, to enter prism 13 where it is again internally reflected from faces 13b, 13c. Thus it finally emerges along path g towards eye-piece 14.

Title: Improvements in the construction of electric heating mantles
IPC: H05B3/34
Filed: 1947-08-26
Abstract: 645,843. Electric heating elements. ISOPAD, Ltd., and REIK, H. Aug. 26, 1947, No. 23517. [Class 39(iii)] An electrically-heated flask or retort mantle 1 comprises several pads 7 of glass wool enclosed by an inner cover 4 of glass fibres and an outer cover 8 of glass fibres or other material. Heating elements 5 are secured to the surface of the inner cover 4 that is adjacent to the pads 7. When the mantle is shaped to the desired form, the heating elements 5 are energized to fuse the surrounding glass wool and, on cooling, a crust 13 forms that is relatively resistant to deformation. The inner cover 4 has a higher melting temperature than the glass wool pads. A top mantle 2, constructed in a similar manner to the lower mantle 1 but not necessarily subjected to a crust forming process, is divided into lobes 17, 18 enabling it to be slipped about the neck or necks of a flask. The heating element 5 is preferably a resistance wire wound about an asbestos core and surrounded by glass or asbestos. Large mantles have several independent heating elements. Relays can be used in conjunction with thermo couples for automatic heat control. The outer cover 8 can be treated with protective paint or it may comprise a metallic or other enclosure functioning as a stand.

Title: Arrangements for handling objects
IPC: B66C1/28
Filed: 1971-04-19
Abstract: 1347065 Article lifting grips SVENSKA CELLULOSA AB 19 April 1971 [11 March 1970] 23602/71 Heading B8H A device (Fig. 1) for handling bales 3 has members 15 (Fig. 3) movable about pivots 48 for engaging (by hooking under) loops of the bale ties 4. The members 15 are pivotable outwardly against spring action from an inoperative position (full lines Fig. 3) to a bale tie engaging position (broken lines) by the action of flexible members 6. These are reeved round pulleys 21, 22, and 14, and are connected to a mounting 46 which is universally connected to an actuating rod 1 slidable in a tubular housing 2. The extended position of the rod 1 is shown in dotdash-lines in Fig. 2 (not shown). In this position, the members 6 are extended so as to pivot the members 15 outwardly into hooking position. When the device is lowered to a surface on which the bale is to be unloaded, the rod 1 moves downwardly in the housing 2 when the bale "grounds" on the surface. The rod 1 is retained in its retracted position by the action of a dog 5 (Fig. 4) which is pivotally mounted at 31 on the rod 1 and is spring-urged into a recess in the housing 2 (as shown in dot-dash lines). This is permitted to occur because a toothed wheel 8, rotatably mounted on the rod 1, engages, and is thereby rotated by, a member 9. The members 15 are spring-urged to their inward (non- hooking) positions due to the retraction of the flexible members 6. When the rod 1 is moving downwardly relative to the housing 2, it engages inwardly projecting stops 32 (Fig. 5) each of which is connected via spring-urged rod 33, links 57, and a linkage 19 (Fig. 5), so as to lower magnetic heads 17 from a normal position (full lines), to the position shown in dot-dash lines. Thus when the device is lowered on to another load, and the hoist (not shown) from which it is suspended is raised, the heads 17 engage the ties of the straps 4. The member 9 (Fig. 4) is deflected upwardly and permits rotation of the wheel 8. This releases the dog 5 from engagement with the housing 2. The rod 1 is thus able to be lifted up and tensions the members 6. These cause the members 15 to move into hooking position. They are able to hook under the ties because the latter have been drawn upwardly, away from the bale, by the action of the magnetic heads 17.
