Abstract: 1,071,025. Delivering sheets. CONSOLIDATED PAPERS Inc. Nov. 19, 1963 [Jan. 21, 1963], No. 45583/63. Heading B6H. A web 16 is cut into sheets by a revolving cutter 24 co-operating with a fixed knife 26. The severed sheets are moved away from the cutter by high-speed conveyers 28, 30 and 36. Each conveyer comprises a plurality of spaced endless tapes. Suction means 42 are positioned beneath the upper runs of tapes 32 to pull the severed sheets away from the cutter. The suction means comprises a transverse pipe divided into separate chambers by semicircular shaped walls. Each chamber is connected individually to a source of suction via a valve 54 and a pipe 48. Thus one or more chambers may be cut off from the source of suction according to the width of the severed sheets. The pipes 48 include flexible sections to facilitate assembly and damper vibrations.

Title: Pressure release device
IPC: H01M2/12
Filed: 1976-11-03
Abstract: This device is arranged in the container wall in order to reduce an internal pressure prevailing in a container, preferably a container (5) of an electrochemical element, and, in a deformation region (11, 12) of said container wall, has at least one weak-point zone (13) which tears in the event of expansion resulting from excessive internal pressure. In order to achieve very precise matching to the desired bursting pressure despite low production costs, hermetic sealing and corrosion resistance, the weak-point zone (15) is slightly deformed and is provided between two adjacent deformed regions (11, 12) of the container wall. If the predetermined container internal pressure is exceeded, the two deformed regions (11, 12) are expanded and the weak-point zone (13) located between them is subjected to expansion until it fractures. <IMAGE>

Abstract: 995,643. Steam turbines. LICENTIA PATENT - VERWALTUNGS -G.m.b.H. Dec. 27, 1961, No. 46287/61. Heading FIT. A multistage axial flow steam turbine has stator guide blades formed with radial passages for the flow of heating steam therethrough mounted at the steam entry to a ring of rotor blades and arranged to act as surface heat exchangers for the addition of heat to the steam flowing towards the rotor blades. Steam turbine guide blades 1 extend radially between, and are welded at their ends to, inner and outer rings 5, 6, Fig. 1. Two radial heating channels 11 in each guide blade 1 are formed by grooves 12, Fig. 2, cut in the concave side of the main body 13 of the guide blade, a cover plate 2 being welded to the axially outer edges 14 of the grooves. The heating channels 11 are connected respectively to two separate grooves 3 formed in the inner surface of the outer ring 6 which extend over the entire periphery of the stage and serve as delivery and discharge connections for the heating steam, which is delivered through one of two pipes 4 from the live steam pipe feeding the turbine, or from the heating steam discharge line or an extractor steam pipe of a preceding stage. Channels 11 of each blade communicate at their radially inner ends through an axial groove 15 in ring 5. The live steam feeding the turbine may be wet steam from a nuclear power plant. Steam from the other pipe 4 is led off to the condenser of the plant, to a subsequent guide blade assembly, to a feed water pre-heater, or to a further heat exchanger.

The invention of the parent Specification is modified by the provision in the cradle and plugs 16, 17, Fig. 1 (not shown) of electric circuits which short circuit the limit switch of the winding motor when the plugs are engaged. These main plugs 16, 17 each contain a silicon controlled rectifier switch energised by a Mallory cell in an assembly 70 and are connected by auxiliary plugs 34, Fig. 2 (not shown) on the end of cables mounted on the cradle and connecting the switches in parallel with the limit switch to short circuit it. The switches being in series both plugs must be engaged. These cables 35, Fig. 10 (not shown) are arranged in the cradle so as to be pulled out when the cradle descends. The main plugs each comprise two concentric tubes 43, 44. The inner tube 44 contains a slidable plunger 53 moved by a pin in the socket on the building so that a pin 56 in the outer tube slides along an axial groove 54 in the plug and enters a circumferential groove 55 in the plunger thus allowing the tubes to be turned relatively and a pin in the socket in the building engaged with a bayonet slot in the end 45 of the plug. Simultaneously holes in the two tubes register allowing insertion of an auxiliary plug 34 (not shown). Also holes register for the engagement of an auxiliary locking plunger, Fig. 7 (not shown). Trip switches, Fig. 11 (not shown) are included in the hoisting circuit to prevent the cradle fouling the plugs in the wall of the building when it is being raised. The guiding rings for the hoisting cables may be offset from the plugs by means of members 47, Fig. 5 (not shown) when the distance between the sockets and cables differs.

Patent GB-479018-A (GB)
Abstract: 479,018. Directing anti-aircraft gun fire; calculating-apparatus. STEVENS, A. H. (Sperry Gyroscope Co., Inc.) May 22, 1936, No. 29088/37. Divided out of 474,225. [Class 92 (ii)] [Also in Group XIX] The data provided by a range-finder, such as slant range (D<0>) and elevation angle (E‹), is converted into other data, including the height (H<0>) and horizontal range (R<0>) for use in the gun fire director, by apparatus which comprises an indicator for slant range, a calculating device controlled in accordance with a function of the elevation angle, and power-operated or manual means to control the calculating device to position a part to match said indicator, the quantity set in by such means being proportional to the height of the target when the indicator is matched. The elevation angle E<0> and slant-range D<0> are fed as known quantities into the computor shown through lines 2, 3, the unknown height H<0> and horizontal range R<0> then emerge through the lines 43, 33. By operating a hand wheel 14 to drive a screw 13 and slotted sector arm 9, the coarse and fine pointers 7, 7<1> are made to follow the indications of the elevation dials E<0>, E<01>, the rotation imparted to the screw being proportional to cot E‹ and the solid cam 15 being translated by this amount through a screw 17 and arm 18. This cam is rotated proportional to H<0> by hand wheels 26 or 27 and the lift imparted to a pin 19 causes a pointer 20 to match the slant-range dial D‹. A second solid cam 16 fast with the cam 15 also receives translation proportional to cot E‹ and rotation proportional to H<0> and lifts a pin 21 to rotate dial R<0> proportional to horizontal range, the dial being followed by pointer 23 by rotating handle 28. A variable-speed gear 36 driven by a constant-speed motor 37 and adjusted by the handle 26 enables a gliding motion of the target to be taken into account by varying H‹ to keep the pointer 20 matched against the slant-range dial, the variations of H<0> passing out of the computor by the shaft 43. Since R<0>=H<0> cot E<0>, changes in R<0> are obtained from a variable-speed gear the disc 70 of which is driven from the shaft 17, the radially-adjustable roller 71 being driven from the shaft 43. The changes are added to the original settings through differential 73, 29 and pass out by the shaft 33. For small angles E‹, D<0> is taken as equal, to R‹ and a triangle is set up by an arm 47 inclined proportional to E‹ and an adjustable nut 46 a slider on which bears on a bar 49, the vertical adjustment of which gives H‹. The azimuth reading is shown on coarse and fine dials A<0>, A<01> and leaves the apparatus by shaft 56 when the dial pointers are followed by rotating a hand wheel 52. Specification 474,225 is referred to.
