Abstract: 868,469. Continuous-discharge mixing apparatus. HUNTLEY & PALMERS Ltd. May 15, 1958 [May 16, 1957], No. 15536/57. Class 86 A continuously operable apparatus for kneading plastic masses comprises, an elongated casing 1, Fig. 1, formed from a plurality of semi-circular shells 2, 3 and 15, 16, the internal surfaces of the shells 2, 3 being provided with straight grooves 14, Fig. 3 parallel to the axis of the casing; a rotor 28 formed from cylindrical sections 38 provided on their external surfaces with helical grooves 40 co-operating with the grooves of the shells, and feeding means at one end of the casing and comprising a hopper 24 with a pipe 25 for liquid ingredients, a single start worm spacer by a sleeve 43 from a double start worm 44 mounted on the rotor shaft within the shells 15, 16 and rods 50 screwed radially into the sleeve 43 co-operating with radial rods screwed into the shells in the space between the worms. The pitch of the worm 44 is slightly greater than that of the worm 42. The lower casing shells 2 and 15 are supported by straight bars 4, 5, 6, Fig 3, carried by transverse webs 7 mounted on two channels of which only one, 9, is shown. The bar 5 fits in a longitudinal groove 10 in the lower shells. The shell pairs 2, 3 and 15, 16 are secured together by semi-circular stirrups 11 each having one end hinged at 12 to the bar 4 whilst the other end is secured by a screw 13, Fig. 2 (not shown) to the bar 6. Inclined side walls 71 connect the bars 4, 6 with the channels. At the right hand end the rotor shaft is connected through a sheer pin 57 with a chain sprocket 54 driven from means not shown. Referring to Fig. 3, when using the apparatus any one of the upper shells 3 is removed and replaced by a shell 3a having an outlet aperture 67 surrounded by walls 68, 69 and having an inclined plate 70 over which the kneaded material is discharged on to a removal conveyer. Alternatively the right-hand end of the casing 1 and the bearing 37 may be removed, the rotor then being carried by the left-hand bearing 32, so that materials are discharged from the end of the casing. Heating or cooling medium is supplied to the interior of the rotor through an elbow 66 whence it passes through a tube 64 and transverse bore 60 to diametrically opposed longitudinal grooves 58 which connect at their left-hand ends by channels 62 to diametrically opposed longitudinal grooves 59. The liquid passes along the grooves 59 back to a transverse bore 61 and thence along a bore 63 concentric with the tube 64, to an outlet elbow 65. In modifications the casing and rotor may rotate in opposite directions or only the casing may rotate. The materials passing through the annular chamber between the casing and rotor sections 38 are kneaded into strips of approximately elliptical cross-section.

Abstract: 1340024 Sheathed heating elements ELPAG AG CHUR 18 May 1971 [21 May 1970] 15573/71 Heading H5H A tubular sheathed heating element, comprising a casing 1, Fig. 3, containing one or more heating resistances 4 embedded in high melting point insulation 2, is provided with additional insulating material 9, 11 immediately adjacent the resistance(s), which additional material softens or melts or becomes conducting before the insulation 2 or casing 1 deteriorates, to allow a leakage current or short-circuiting of the resistance(s), thereby protecting the resistance(s) or casing from burning out or melting when the element temperature gets excessively high. The leakage current, or increased current passed, causes a fuse or safety device in series with the element to switch off the element. Resistance 4 may be mounted on a glass fibre hose 9 over a conducting core 5 and/or is surrounded by a glass fibre hose 11. The ends 4a of resistance 4 are connected with portions 7 of a termination 6, which may be separate from or integral with the core 5 at one end, Fig. 5 (not shown), the latter arrangement giving preferential breakdown of the additional insulation at that end. A heating resistance 3, Fig. 7 (not shown), has two inner cores 32, 33, each connected to one terminal portion 7 and mutually insulated by wound-on glass silk or glass hoses 34, 35, which insulation also insulates the cores from the resistance 3. Two heating resistances 36, 37, Fig. 8, with glass-fibre insulation 42 have terminals 38, 39, at one end and are connected to a conducting termination 41 in insulated or non-insulated fashion. It is thus possible to energize either or both resistances 36, 37. Alternative insulation materials include spun stone wool or enamel layers, particularly on the conducting cores.

Abstract: 1310323 Selective signalling THOMSONCSF 18 May 1971 [22 May 1970] 15649/71 Heading G4H Claimed separately are: (a) a data coder (Fig. 1) for producing messages comprising a sync. signal, and m successive bit pulses each having a duration To or T 1  according to the bit value, the coder having m monostable multivibrators M 1 -M m  connected in series, the time constant of each being adjusted according to the value of a respective input bit to one of the values To + T i  or T i  + T i  (where T i  is fixed), and means for shortening the pulses produced by the monostables by T i  and supplying them to an output (at 11) separated by intervals of duration T i , (b) a corresponding decoder (Fig. 2) which recognizes the sync. signal (at 13) to set the first of a series of m bi-stable multivibrators Q 1 - Q m , and has coupling means P 1 -P m  whereby the trailing edge of each bit pulse in the message (at E) resets a corresponding one of the bistables, this setting the next bi-stable (if any) in the series, and m output circuits coupled to the bi-stables respectively for delivering one or the other of two predetermined signals (at Z 1 -Z m ) according to whether the duration of the pulse signal delivered by the associated bistable Q 1 -Q m  is To + T i  or T 1  + T i . In the coder (Fig. 1), each of m-2 inputs C 3 -C m  causes a resistor r 3 -r m  to be switched into or out of the supply circuit of a respective monostable M 3 -M m  of the series to select its time constant. According to whether or not any of these inputs equal to 1 is urgent, OR gate 1 and means not shown similarly select the time constant of monostable M 1 . Monostable M 2  similarly indicates whether or not any of the inputs equal to 1 is non-urgent. Monostable 3 provides a (long) sync. signal. When a monostable in the chain 3, M 1 -M m  returns to its stable state, it triggers the next monostable (if any) in the train, and via a respective differentiator D 0 -D m  and OR circuit 9, triggers an output monostable 10 having a time constant T i , the non-stable state of this output monostable corresponding to the intervals between pulses in the message. In the decoder (Fig. 2), each bit pulse, applied at E, produces a constant-duration pulse at 30, starting at the leading edge of the bit pulse, and a short pulse at 31 at the trailing edge of the pulse at 30. For each message bit, one of two AND gates F, G sets or resets a corresponding output bi-stable H according to the bit value, under the control of the outputs of the bistables Q 1 -Q m  and the coupling means (NANDs) P 1 -P m  as shown.

Abstract: 834,784. Steam and gas-turbine plant. BABCOCK & WILCOX Ltd. June 1, 1956 [June 3, 1955], No. 15962/55. Class 110 (3). [Also in Group XIII] A water-tube boiler forming the steam raising part of a power plant particularly for marine use which comprises a steam turbine 81 and a gas-turbine 82 comprises two identical units 1, 2, each including a first and second section 3, 4. The first section 3 consists of a marine boiler 5 similar to that described in Specification 714,050 while the second section consists of heat exchangers disposed in an upright gasturbine exhaust gas passage 6 separated by a metal partition 47 from the marine boiler. The latter has a tube-lined furnace 7 fired by burners 8, hot combustion gases leaving the furnace through a screen 24 and flowing through parallel passes 14, 15 containing convection generating tube banks 23 and 25, 26, respectively, the pass 14 also containing a superheater 11. The gas flows are proportioned between the passes by adjustment of outlet dampers 21, 22. The passage 6 which receives the exhaust gases from the gas turbine 82 at its lower end contains a superheater 48, an evaporator bank 49 and a steaming economizer 53. The gases from the marine boiler mix with those from the passage 6 in a space 61 and flow upwardly through flues 12, 54 respectively locating an air heater 13 and an economizer 55 to a stack. The steam-water mixture generated in the furnace lining tubes and in the convection heating portions of sections 3, 4 passes into a drum 9 whence steam flows serially through the superheaters 48, 11. During normal operation, with the gas and steam turbines operating at nominal power output, the desired degree of superheat is obtained with the proportioning dampers 21, 22 fully open and the steam temperature at other loadings is maintained constant by adjusting one or other of the dampers. If the gas-turbine is not operated and the firing rate of section 3 is increased to maintain the same steam output to the turbine 81, the superheat temperature does not tend to rise in view of the location of the superheater 48 in the then unheated passage 6.
