Title: Method and means for the recovery of heat
IPC: F22B1/18
Filed: 1956-10-22
Abstract: 839,125. Power-generating systems. ELECTRICITE DE FRANCE - SERVICE NATIONAL. Oct. 22, 1956 [Oct. 27, 1955], No. 32170/56. Class 122 (3). [Also in Groups XIII and XL (a)] To recover heat from a hot fluid, e.g. coolant from a nuclear reactor, passing through a casing 1, water under pressure is heated in an economizer 2 and stored in a container 5 outside the casing 1. Part of this water is vaporized at 7 and superheated at 10 to supply the high-pressure stage of a turbine 22. The remainder of the water from the container 5 passes through evaporators 13, 18, in which part of it is vaporized by reduction in pressure and superheated by the rest of the water. This superheated steam passes to lower pressure stages of the turbine 22. Water from a condenser 24 and evaporators 13, 18 is returned to the economizer 2 by a feedwater pump 3. In alternative systems, steam from the evaporators is superheated in the casing 1 and may be used to drive auxiliaries instead of being introduced at low pressure stages of the main turbine. The high pressure steam may drive a separate turbine on the same shaft as the lowpressure steam turbine. Valves 14<1>, 19<1> control flow of vapour through evaporators. Specification 795,007 is referred to.

Patent GB-780398-A (GB)
Title: Process for the manufacture of pressure-filled seamless hollow articles
IPC: B29C41/06
Filed: 1955-11-14
Abstract: Pressure-filled seamless hollow articles are moulded (see Group V) from isocyanate-polyester plastic material of which a suitable composition comprises 100 parts by weight polyethylene adipate, 18 parts by weight naphthalene diisocyanate-(1,5) and 2 parts by weight butane- or butene-diol-(1,4).ALSO:Pressure-filled seamless hollow articles are moulded by a process wherein mouldable and heat hardening plastic material is centrifuged in a closed pressure-filled mould.  To mould a ball the material is placed in a two-part spherical mould fitted with a filling valve whereby, when the mould is closed, internal pressure may be set up in it.  The mould is then given a compound rotary motion and the material thus centrifuged to form an even layer on the inner wall, while heat is applied to cure the material.  After cooling the mould is opened and the article removed as a seamless ball with internal pressure.  As a material isocyanate-polyester is mentioned as suitable, having low gas permeability.  In a modification the material may be removed from the mould before it has set and, when heated, expands freely under the influence of the internal pressure and cures when stretched to give a thin-walled ball.  The process and its modification are illustrated by two examples using a specified composition. Another material mentioned is plasticised polyvinyl chloride.  The invention is adaptable to the production of meteorological balloons.

Title: Improvements in or relating to electrically driven timepieces
IPC: G04C1/02
Filed: 1925-12-23
Abstract: 249,078. Juillerat, M. A. March 16, 1925, [Convention date]. Electric clocks; driving -mechanism, main spring.-An electrically-driven watch or clock having self-contained means for re-energizing the main spring is provided with means for maintaining the drive during such re-energization. An electromagnet 10 has a U-shaped yoke 11 and a winding 13 connected to a negative terminal 27 and to a terminal 24 connected in series with a positive terminal 20. The armature 14 is pivoted to the lower limb of the yoke and carries a. member 17, 18. Fixed to the same limb is a blade spring 15 constituting the main spring and this normally bears to the left against the head 16 of a screw carried in the member 17, which also supports a leaf spring 22 coacting with the contact 20. The member 18 carries a pawl 35 co-operating with a ratchet wheel 30 of 60 teeth. This wheel is mounted loosely on the minute wheel arbor 31 and has a pin 32 coacting with a spring 33 on the arbor 31 and with a pin 34 on a wheel of the time-train which has an escapement, not shown. On the opposite side the wheel 30 coacts with a pawl 36 on a blade 25 so that when this pawl slips off the point of a tooth the blade 25 makes contact suddenly with the terminal 24. The device is arranged to energize the spring 15' once a minute in the following manner. In the position shown the magnet has been energized at the end of a minute and has attracted the armature breaking contact at 20 and moving the pawl 35 behind the next tooth. The spring 15, re-energized, now pulls the pawl 35 to the left, slightly winding up initially the auxiliary spring 33 and driving the time train. This continues until contact is again made at 20 and in the meantime pawl 36 rides up a tooth breaking contact at 24. Near the end of the next minute contact is made at 20 as the spring 15 reaches the limit of its travel and shortly afterwards the pawl 36 slips off its tooth and contact 24 being suddenly closed in series with contact 20, the magnet is energized to re-energize the main spring. During such reenergization of the main spring the pawl 36 prevents retrograde movement of the wheel 30 and the initial compression of spring 33 is used to continue the drive of the time train. Specification 16814/04 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) also describes and illustrates an adjustable stop for limiting the travel of the member 18. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,044,957. Velocity-modulated tubes. SPERRY RAND CORPORATION. Aug. 19, 1963 [Aug. 20, 1962], No. 32751/63. Heading H1D. An electrode assembly for the gun of a velocity modulation tube includes a control grid closely spaced from the cathode and formed by an assembly of similar open-ended cells, the distance between the electron-emitting surface of the cathode and the further surface of the grid lies between 0À25 and 0.50 of the cell spacing, and the depth of the grid lies between 0.10 and 0.25 of the cell spacing, whereby the beam may be controlled without the use of positive grid bias, and without undue aberration of the beam. The electron gun of a klystron or travelling wave tube includes cathode 11, grid 12, and an accelerating anode 20, beam current flowing whenever grid 12 receives a positive pulse from modulator 28. The modulator pulses are insufficient to drive the grid positive with respect to the cathode, thereby avoiding grid current effects, the emission of electrons into the beam from areas of the cathode directly beneath the grid elementswhich electrons provide the major contribution to aberration effects-being inhibited by the closeness, and negative bias, of the grid, which is made sufficiently deep to ensure that its surface furthest from the cathode can exercise an adequate control over the beam. The grid cells may be of square or rectangular cross-section; numerical values for the ratios between the grid cell spacing, the grid depth, and the grid/ cathode spacing, are given.
