Title: Arrangement for limiting the automatic rotations of a telescope
Inventor: FEHLKAMM GUNTER
IPC: G02B23/16
Filed: 1966-10-10
Abstract: 1,149,748. Controlling the motion of telescopes. CARL ZEISS JENA, VEB. Oct.10, 1966, No.45211/66. Heading G2J. [Also in Division H2] An arrangement for limiting the automatic rotations of a telescope 1 comprises a template 14 carrying the limit information 17, a scanner 45 which picks up the limit information and influences the telescope drive means, and means for effecting relative motion of the template 14 and the scanner 45, this motion corresponding to movement of the telescope. The telescope 1 is driven about axes X 1 X 1 , X 2 X 2  by motors 6, 9 respectively. The template 14 is mounted by sliding movement in two perpendicular directions within its own plane. Rotations of the telescope 1 about the axis X 1 X 1  are transmitted via a receiver 25 to a spindle 20 so as to slide the template 14 along the spindle 20. Similarly, rotations of the telescope about the axis X 2  X 2  cause rotations of a spindle 22 perpendicular to the spindle 20, and thus move the template 14 along the spindle 22. In the embodiment of Fig. 1 the limit information 17 is defined by the boundary between transparent and opaque zones 15, 16 of the template. Light from a source 42 is received by the photo-electric cell 45 which is coupled to a switch 44. The motors 6, 9 are also coupled with the switch 44. When the boundary 17 moves between the source 42 and the photo-cell 45 the current signal in interrupted and the switch 44 is displaced to operate a warning signal 47 and disconnect the motors 6, 9. It is possible to then change to hand control of the telescope 1 through further displacements close to the limit position, which is indicated by the warning system 47 also being disconnected. In a modification Fig. 2 (not shown) the template (14) is formed in relief and a mechanical feeler is arranged to move over the surface of the template and engage an electrical contact connected to the switch 44. In a further modification Fig. 5 (not shown) the template is formed by a cylinder which carries on its inner surface an electrically conductive layer connected to a current source. The scanner is again connected to the switch (44) and is carried on a rotatable spindle for movement over the electrically conductive layer. The second component of telescope rotation is translated into rotation of the cylindrical template.

Abstract: 1450798 Two-part couplings CANNON ELECTRIC (GREAT BRITAIN) Ltd 19 Sept 1974 [27 Sept 1973] 45217/73 Heading H2E An electric connector for terminating a multiconductor cable comprises two similar cover portions 101 of resilient plastics material, e.g. nylon or polyester fitted to a contact housing 100 by holes 1, 2 and notches 102 matching projections 11, 12 on the housing, the housing 100 carrying two or more rows of female contacts 17 and each cover portion having internal reinforcing ribs (8, Figs. 3-5, not shown) and a recessed area 9 for a label. The housing 100 comprises two parts (Figs. 6-13, not shown) joined together by ultrasonic welding, the upper part carrying the projections 11, 12 and also projections (12A) fitting into recesses (13) in the lower part. A hood 19 (Fig. 14) can be fitted to the housing to protect the contact tails 18 when not in use. Each contact 17 can be removed from the housing after disengagement of the locking tongue 16 by a flat tool (not shown). Each row of contacts 17 is engaged with a row of square-section male contacts 31 (Fig. 16) mounted in an insulating frame 30, e.g. of polyester, the frame having bosses with holes 32, 33 on one face and bosses with studs on the opposite face so that a number of frames can be fitted together and held together by plastic strips with slots 36 fitted to end tags 34, 35 on the frames, the resulting assembly being located in a metal frame. The plastic strips carry fingers with slots 39 which engage projections 37 on the housing 100 when a connector is engaged reducing the risk of accidental withdrawal, and ribs 40 which partially collapse when the frames are assembled together to assist in accurate positioning. The fingers may be bifurcated (Fig. 24, not shown) to increase the pressure of engagement with the projections 37 and to co-operate with projections 37 on connectors in adjacent rows when several rows of connectors are assembled side by side. In the embodiment shown the cover has cable entries 3, 4 and the cover portions are non- interchangeable and held together by bolts 5; in alternative embodiments there may be only one cable entry (10, Fig. 2, not shown), the holes and projections may be symmetrical and the cover portions interchangeable (Figs. 19-22, not shown) or the cover portions may be held together by snap fasteners (Fig. 25, not shown).

[Also in Division F4] Temperature and pressure conditions in a steam turbine TU forming part of a steam/ electric power plant are controlled during startup and shutdown by a throttling and shut-off valve system comprising valves A, B located between the evaporating and superheating sections of the steam generator combined with control both of the firing rate and of the rejection or conservation of heat from the evaporating section; the latter control feature which is particularly used during startup involves by-passing a part or all of the evaporating section flow to a flash tank FT through a further control valve R. From the flash tank steam or drain water may be rejected to a condenser CO or may be conserved by use in feed water heaters HPHI, HPH2 and in a feedwater deaerator system DE, DES. Steam at lower pressure than exists in the evaporator may also pass to the superheater through valve V. During startup turbine steam and metal temperature measurements are used to control the quantity and pressure of steam passing through the valve V into the superheater, valves A and B being closed initially, and to vary the firing rate and also the degree of rejection or conservation of heat from the evaporating section flow. When the superheater pressure reaches the normal maximum working pressure of the flash tank FT, valves A and B may be progressively opened and valves R and V progressively closed. The feedwater system includes a demineraliser CFD, low pressure heater LPH, high pressure heaters HPH1 and HPH2 and a deaerator system which is provided with its own separately fired heater D for startup purposes.
