Title: Telescopic crane jibs
IPC: B66C23/70
Filed: 1973-09-20
Abstract: 1390469 Telescopic crane jibs LEO GOTTWALD KG 20 Sept 1973 [28 Sept 1972 7 Oct 1972] 44232/73 Addition to 1340978 Heading B8B [Also in Division E2] A telescopic crane jib comprises a number of telescopic parts 3, 4, 5 with a fluid pressure operated cylinder 9 having a piston-rod 8 secured to bottom part 2 of a jib housing 1, 2 for extending and retracting the parts with the longitudinal axis of the jib at least substantially vertical, as described in the parent Specification 1,340,978, there being locking means 18 at the ends of the telescopic parts for locking them together when extended. As shown the cylinder 9 is secured to a carrier 6 guided by rollers 12 running on surfaces 13 in the lower portion 2 of the jib-housing 1, 2 which surrounds the telescopic parts 3, 4, 5 when retracted, their bottoms 15, 16, 17 resting on one another and on the support 6. The upper portion 1 of the jib housing 1, 2 may be telescoped into the lower portion 2, Fig. 24 (not shown). The support 6 is constructed as a carrier for one or more lifting drums (30), Fig. 8 (not shown), and their drive members. Figs. 10, 11 show the locking means 18 in connection with the telescopic parts 3, 4. When extended to the position shown in Fig. 11 a stop 46 on part 3 engages a rocker 44 causing it to engage a sensor 45 which emits a pulse leading to the actuation of a power cylinder 34 to urge a locking bolt 37 into contact with stop surface 55 of a stop plate 53. At the same time a locking sleeve 41 is urged by a spring 43 to the left (as shown) to bear against the stop surface 55. Slight lowering of the part 4 now brings the bolt 37 into line with locking bore 52 so that, on the further application of pressure by the power cylinder 34, the bolt 37 slides into the locking bore 52, as shown in Fig. 10, to lock the parts 3, 4 axially together. A retaining groove 56 is provided on the nose of the bolt 37 into which a locking washer (not shown) may be inserted to prevent accidental release of the bolt 37. In a modification of this locking means the locking sleeve 41 has a bevel (64), Fig. 16 (not shown), to take up longitudinal shear by co-operating with a contact surface (66). A nose 49 on the locking sleeve 41 ensures that the locking bolt 37 can only be released when the part 4 is raised slightly. In a further modification of the locking means 18 the locking sleeve 41 is omitted, Fig. 18 (not shown), the safety feature of the nose 49 thereon thus being omitted. A catch mechanism 21 used to support the telescopic parts 3, 4 and 5 during the extension and retraction is similar to the locking means 18 but is mounted for displacement vertically against a spring (82), Figs. 21 to 23 (not shown) and the nose 49 on the locking sleeve 41 is absent.

Abstract: 1,058,036. Semi-conductor devices. RADIO CORPORATION OF AMERICA. Oct. 29, 1964 [Nov. 26, 1963], No. 44247/64. Heading H1K. A semi-conductor PN junction device is made by masking a limited area of a wafer of one conductivity type, the area having a peripheral notch, depositing material of the opposite conductivity type over the unmasked area including the notch to form the junction, depositing metal over the masked area and over the deposited material in the notch, removing part of the material within the notch and finally providing contacts to opposite sides of the junction. Typically tunnel diodes are made by masking notched areas 14 (Fig. 2) on a degenerately doped N-type germanium wafer 10 with evaporated silicon monoxide, magnesium fluoride or oxide, or with a colloidal suspension of magnesium hydroxide. Degenerate N-type germanium is epitaxially deposited over the unmasked area and then one or more metals such as chromium, aluminium or gold are evaporated through a mask to cover the masked areas and notches. After dicing into individual elements of the form shown in Fig. 6 the epitaxial layer in the notch is etched with concentrated potassium hydroxide or electrolytically etched to reduce the junction area to ¢-1/5000 of its original value. Other semi-conductors such as silicon, indium phosphide, gallium arsenide, cadmium sulphide and silicon carbide may be used instead of germanium.

Patent GB-1005246-A (GB)
Title: Improvements in or relating to electrophotographic materials
IPC: G03G5/087
Filed: 1961-12-14
Abstract: The light sensitivity of zinc oxide powder which is to be incorporated in electro-photographic material is reduced by treating the powder surface with a salt of aluminium, bismuth, chromium, copper, iron, lithium, magnesium, nickel, tin, or titanium so that the metal salt combines with at least 10% of the surface of the oxide particles.  Metal salts exemplified are the chlorides of nickel, magnesium, lithium, chromium, aluminium, ferric iron, and cuprous and cupric copper, the iodides of bismuth and stannous and stannic tin, and tetra-iso-propyl titanate.  The zinc oxide powder is treated with the metal salt in the manner described in Specification 1,005,245 and is similarly incorporated in electro-photographic material. Reduction of the light efficiency of the zinc oxide by the treatment of the present invention reduces the sensitivity to blue and ultra-violet light but if the modifying metal salt is also by virtue of its acid portion, a Lewis acid, the oxide becomes capable of absorbing any desired dyestuff sensitizer so that, for example, the overall sensitivity of the oxide to white light may be increased. Crystal violet is the dye used in the example given.  Specification 1,005,247 also is referred to.
