Title: Improvements in or relating to electrical supply equipment
IPC: H01H35/34
Filed: 1962-12-12
Abstract: 963,347. Distribution boxes; electric conduits; sleeve couplings; cable and wire couplings. TELEMECANIQUE ELECTRIQUE. Dec. 12, 1962 [Dec. 18, 1961], No. 46990/62. Headings H2C and H2E. In a power distribution system with plug-in tapping as disclosed in Specification 927,248, adjacent conduit sections are polarized to prevent the conductors carried therein from being transposed on coupling. Supply conductors 5, contained within a conduit section 1 comprising a channel 2 lined with insulating material 4 and a closure strip 3, are symmetrically disposed about a longitudinal midplane of the conduit 1, and two sections 1 are joined end to end by means of shells 17 with flanges 17a which surround the abutting ends of channels 2 and by a cover member 20 which closes in a gap left between the ends of strips 3 for adjustment of a coupling member 11 connecting conductors 5, incorrect alignment of conductors of different phase or potential being prevented by end lugs 18 on one shell flange 17a co-operating with corresponding apertures 16 asymmetrically positioned in the ends of strips 3. The coupling member 11 (Fig. 4, halfsection, and Fig. 5, not shown), comprises a pair of metallic sleeves 12, each with two set screws 13, the sleeves 12 being embedded in a plastic support 14 so shaped that the screw heads are accessible through the gap between closure strips 3. The cover 20, Fig. 1, has end lugs 25 which engage shell notches 21 in position 20A, Fig. 3, from which position it is rotated to its closure position and locked by a set-screw 27 to the end of strip 3. An end-plate 54, Fig. 1, which may have a cable opening, is positioned over shells 17 at the end of a supply line and has apertures 16 to receive shell lugs 18. For branching-off the main line, a T- shaped coupler, Fig. 1, comprises a pair of channel members 29, 30 and a block of insulating plastic 39 in which are embedded four T-shaped conductors (Figs. 6, 7, not shown). The channel 30 has shorter arms than channel 29, and the remaining space is filled by straps 32 which have spacer inserts 33 (Fig. 11, not shown), with a lug at one side for co-operation with an aperture 16 in a straight conduit section 1. For different directions of the line, two different types of strap 32 are provided, having lugs at opposite sides to indicate the neutral conductor. As in a three-phase system a neutral conductor may extend along either side of the main line and along either side of the branch line, depending on the requirements of the system, four different types of T-coupling are provided (Figs. 8a, 8b, 8c, 8d, not shown). A cruciform coupler is also described (Fig. 9, not shown).

Patent GB-1347988-A (GB)
Title: Sheet unloader
IPC: B65H29/10
Filed: 1971-10-20
Abstract: 1347988 Delivering sheets WARNER & SWASEY CO 20 Oct 1971 [14 April 1971] 48729/71 Heading B8R A device 10 for delivering sheets 24 to a stack 48 is substantially the same as that described in Specification 1,341,978 but the clamps 112 on the horizontally reciprocable trolley 56 are movable, e.g. by pneumatic cylinders 76, relatively thereto from the illustrated extended position to a retracted position, Fig. 5 (not shown). Thus, whilst a sheet is being punched by the machine 12, and thereafter moved to an unloading location by a slide (30), Fig. 1 (not shown), the trolley 56 can remain adjacent this location, with the clamps in the retracted position, without interfering with the slide movement. The clamps then extend and close upon the sheet, workholders on the slide (30) are released and the trolley moved to transport the sheet over the stack. The trailing sheet edge is sensed by a roller 164 which sets a timer such that when the edge approaches the end of a guide 62, the trolley is stopped and the clamps moved to the retracted position and opened. Thus the sheet drops to the stack without being dragged thereover. (For Figure see next column.)

Patent GB-1456297-A (GB)
Title: Method of operating a nuclear power plant during periods of decreased reactivity
IPC: G21D3/08
Filed: 1974-11-18
Abstract: 1456297 Nuclear power plant WESTING- HOUSE ELECTRIC CORP 18 Nov 1974 [28 Nov 1973] 49744/74 Heading G64 In a method of operating a nuclear power plant (incorporating a reactor using pressurized water coolant) during periods of decreased reactivity, e.g. during a xenon transient or beyond the end of its normal fuel cycle, the reactor coolant temperature is lowered to produce a concomitant rise in reactivity and the turbine loop is modified to accommodate steam of reduced temperature and pressure. In one embodiment, the primary loop 14 of a pressurized water reactor 12 is associated with sensing means 68 for sensing temperature of the water at the inlet 71A and outlet 71B of the reactor core. The turbine loop 16 includes a high pressure turbine 30 whose inlet orifice 32 is smaller than that 42 of a subsequent low-pressure turbine 40. Condensate returns to the secondary side of the steam generator 18 via series-connected feedwater heaters 56, 58, 60 each having an associated by-pass line including a valve 72, 74, 76 operable by the sensing means 68. When, at the end of the normal fuel cycle in reactor 12, the sensing means 68 detects a predetermined temperature drop in the primary coolant, the valve 72 opens thereby effectively eliminating the feedwater heater 56. The effect of this is (a) further to reduce the primary coolant temperature and (b) to increase the enthalpy difference between steam leaving the steam generator 18 and feedwater entering it. The reduction in primary coolant temperature causes a rise in reactivity (due to the increased density-and therefore, moderation effect ofthe coolant) whereby the thermal output of the reactor 12 is returned to its rated value; and the increased enthalpy difference ensures that the electrical output of the plant is retained only slightly below its rated value. Successive feedwater heaters 58, 60 are by-passed as successive predetermined temperature drops in primary coolant are detected by the sensing means 68. In a first modification (Fig. 3, not shown), a common by-pass including a single valve (78) is provided across all the feedwater heaters. In a second modification (Fig. 4, not shown) a feedwater heater is effectively eliminated by closure of a valve (80) in a hot fluid feedline (82) to the heater. In another embodiment (Fig. 5, not shown) the regulation of flow rate in the turbine loop 16 is utilized to produce the required effects. This is achieved by providing a by-pass line across the high-pressure turbine 30, such line including a valve (84) operable by the primary coolant temperature sensing means. During xenon transients, override can be effected so as to restore the load-following capability of the plant. This is achieved by the same measures as described above, viz. lowering primary coolant temperature thereby to increase reactivity, and adjusting flow rate or feedwater temperature to increase the enthalpy difference in the turbine loop.

A planar transistor has emitter and base regions of a smaller lateral area than a collector region and connected to metallic electrode areas overlying the collector region on an insulating layer. A screening layer is provided between one of the electrode areas and the collector region and is interconnected to the other electrode area by at least one metallic stripe extending over the insulating layer. The screening layer, which is separated from the overlying electrode area by the insulating layer, is a metal layer isolated from the collector region by insulation formed between them. The two embodiments described are NPN silicon transistors. One of these has its base electrode screened from the collector and is to be used in a common emitter emplifier and the other has its emitter electrode screened and is to be used in grounded base configuration. In both an N-type wafer is first provided with boron-doped base region 3 by diffusion through an apertured oxide layer and subsequently with two partial emitter regions 2 by indiffusion of phosphorus. In the embodiment shown screening layer 108 is formed on the oxide layer and is covered by an insulating layer 109 of photo-resist, lacquer or silicon oxide. The base 6 and emitter 5 electrode areas are then formed at the same time as the stripe 11 interconnecting the screening layer with the base electrode area. In the other embodiment (Figs. 11 and 12, not shown) a screening layer (128) lies under the emitter electrode area (5) and is connected to the base contact area (6) by fingers (17) and interconnecting stripes (27) which are kept in a straight line to keep the output shunt capacitance low. The transistors are completed by the provision of collector electrodes and by encapsulation. The Specification also describes but does not claim a construction like that shown (Fig. 9) but wherein the metal screening layer is replaced by semi-conductor region of opposite conductivity type to the collector region and formed in the surface thereof. A similar construction is described corresponding to Fig. 11 (not shown) and is claimed in the parent Specification.
