IPC: F02C7/277
Abstract: 1,054,680. Gas turbine engines; turbine turning gear. BENDIX CORPORATION. Oct. 8, 1963 [Oct. 11, 1962], No. 39695/63. Headings F1G and F1K. A starting system for a turbine engine comprises a hot gas generator having a compressor driven by a first turbine and supplying compressed air to a combustion chamber, a second turbine for starting the turbine engine and connected to the latter through speed reducing means and an overrunning clutch, the two turbines being supplied with hot gases from the combustion chamber, and hydraulic means and control means arranged to rotate the compressor and to provide selfsustaining combustion. The compressor 13, Fig. 1, of the starting system supplies air to a combustion chamber 17, the combustion gases passing successively through a turbine 27 driving the compressor and integral therewith and through a turbine 31. The shaft 29 of the compressor is hollow, and the shaft 33 of the turbine 31 passes through it and is connected through reduction gearing 47 and an overrunning clutch 49 to a jetpropulsion engine (not shown) which is to be started. A hydraulic accumulator 119 is pressurized during a previous starting operation or manually by a pump 117 or by means of gas introduced through a valved inlet 122. When a manually-operated valve 127 is opened, fluid from the accumulator 119 passes through line 113 to drive a hydraulic pump-motor 41 as a motor for turning the compressor 13 through an overload disc clutch 39 and reduction gearing 37, the fluid returning through a line 101 and a valve 81 to a reservoir 107. A fuel pump 83 driven from the compressor shaft 29 delivers fuel through a line 67 and a check valve 63 to a nozzle 21, ignition being provided by a spark plug 23 energized through an ignition coil 135 by a generator 129 driven from the shaft 29. If the combustion chamber temperature, as sensed at 76, becomes excessive, a valve 62 shuts off the fuel supply. When the combustion chamber pressure reaches a predetermined value, a piston 73 opens a switch 79 to interrupt the ignition circuit and extinguish a signal light 134, whereupon the pilot closes the valve 127; and a piston 77 turns the valve 81 to the position shown in Fig.2 to enable the pumpmotor 41, now acting as a pump, to re-charge the accumulator 119 from the reservoir 107. The fuel pressure is now sufficient to open a valve 64 to allow additional fuel to be sprayed through a nozzle 19, and maximum power is then developed. The turbine 31 reaches a speed sufficient to start the jet-propulsion engine, and a centrifugal device 53 moves a valve 60 to the open position shown in Fig. 2 (whereupon hydraulic pressure holds the valve in this position), allowing pressure fluid to close a valve 61 to shut off the fuel supply and terminate the starting cycle (a further centrifugal device 55 would also open the valve 60 in the event of the shaft 29 overspeeding). The starting cycle can also be terminated at any time by closing a safety switch 95 to open the valve 60 by means of a solenoid 97. In a modification, the closing of valve 127 is done automatically by means of the piston 77.

Abstract: 1,225,250. Laminates. REICHHOLD CHEMICALS Inc. 5 Jan., 1968 [6 Jan., 1967], No. 56192/67. Heading B5N. [Also in Divisions B2 and B6] A matrix suitable for use in preparing plastics or electrotype printing plates is produced from a blank in the form of a laminate comprising a thermoplastic film 11a supported on a substrate of impressionable fibrous material 12a impregnated with a polymeric thermosetting material adapted to restrict the thermal distortion of the subsequently applied intaglio image in the surface of the film 11a at temperatures above about 250‹ F. A layer of clay-filled phenolic resin 12b or adhesive (20), Fig. 3 (not shown), may be located between the film 11a and the material 12a. The film is not more than 5 mils in thickness and is substantially non-hydroscopic, has an elongation in excess of 100%, and has a smooth exposed low surface tension surface with suitable parting properties for the production of printing plates. The surface adjacent the coating 12b may be corona-treated to increase its adhesion. Suitable materials for the film are stated to be polytetrafluoroethylene, polymonochlorotrifluoroethylene, or polypropylene. The polypropylene may be laminated with a nylon sheet (16), Fig. 2 (not shown), the nylon sheet being located adjacent the substrate to act as a bonding agent. Examples of suitable thermosetting resins are stated to be phenol formaldehyde, melamines, polyesters or epoxy resins. Two layers of fibrous material such as a wood or cotton fibre paper product may be used, the layer adjacent the film 11a containing more thermosetting resin than the other layer. For electroplating, the edges of the imaged surface are water-proofed with a lacquer and silver nitrate is sprayed on the polypropylene image to render it electroconductive. An image adapted to produce a plate having a definition above about 100 lines per inch is moulded on the blank using heat and pressure so that the film softens and a relief surface is impressed into the film and the substrate, Fig. 5 (not shown). As the substrate becomes rigid the depressions therein are irreversibly hardened. In the embodiment of Fig. 4 (not shown), the substrate includes a thick asbestos layer (26), which is not necessarily impregnated with resin.

[Also in Divisions F4 and G1] An apparatus for feeding fluidized pulverulent or granular material at a substantially constant rate to a hopper 30, comprises an inclined band conveyer 6 having an upwardly moving conveying run to which an overlying cover 11 is sealed, forming a closed duct having a lower inlet 28 and an upper outlet 14, and means for maintaining the height of material in a shaft 18 connected to the inlet 28 substantially equal to the height between the duct inlet and outlet, so that a substantially constant pressure head of material in the shaft 18 is applied to the material moving along the closed duct. The material having been previously aerated, is fed to the shaft 18 by a worm conveyer 23 and is maintained at the said height by adjustable overflow plates 25 adjacent outlets from the shaft 18, the outlets being in communication with a reservoir for the material. The shaft 18 is coupled by a flexible seal 20 to a collar 15 extending from the cover 11, and the collar may include nozzles for injecting fluidizing air into the material if the initial aeration is insufficient. The conveyer. 6 and its frame 1 are balanced in an inclined position on knife edges 2 and any tendencyfor the frame to tilt due to variation in the density of material on the conveyer 6 is registered by a load cell 33 which controls the conveyer drive motor such that a constant rateby weight of material is delivered to the hopper 30. In the embodiment of Fig. 4 (not shown), the material flowing over the level control plates is caught in a gutter where it is fluidized for subsequent discharge therefrom. In the embodiment of Fig. 5 (not shown), the material'level in the supply shaft is maintained by a pressure sensitive device therein which controls the screw conveyer supplying the material. In the final embodiment of Fig. 6 (not shown), the screw conveyer is replaced by valve controlled gravity feed system, the valve being actuated by a pressure sensitive device as in the last said embodiment.

Abstract: 1,259,564. Cigar-making machines. A.M.F. Inc. 30 Dec., 1969 [10 Jan., 1969], No. 63254/ 69. Heading A2C. Patches P, i.e. portions of tobacco leaf or manufactured tobacco sheet &c to be applied as binders or wrappers to cigars are spaced on a web 34 of porous material wound into a roll 32 and drawn past a perforated box 44 and roller 92 onto a roll 94 driven intermittently by an electric motor 104. The box 44 is divided into a compartment 46 connected at 64 to a vacuum source, and a compartment 48 connected at 86 to a source providing a higher degree of vacuum, the two compartments being interconnected by a normally open valve 54. The roll 32 is carried by an arm 38 urged upwardly by a spring 42 so that the web 34 is constantly urged against the lower face of the box 44 and the patches are held flat by suction as the web is unwound. When a patch covers holes 66, or a single hole, in the base of the compartment 48 the degree of vacuum in that compartment increases which causes closure of the valve 54 and subsequent operation by a pressure transducer 90 of an electric relay which stops the motor 104 and causes operation of a valve 126 to isolate the chamber 48 from the vacuum source. The relay also controls a further circuit which, provided a switch 120 is operated by the correct positioning of a plunger 22 below the compartment 48, energises a solenoid which lifts the plunger to bring a hollow, perforated head 20, connected at 24 to a vacuum source, into contact with the patch. A timing device subsequently causes de-energisation of the solenoid to allow descent of the plunger 22 with the patch, and also affects the relay to restart the motor 104 and open the valve 126. The timing device also initiates rotation through 180 of a turret 10 to bring the patch to a station 14 where a roller 30 is pressed against a die 16 to cut the patch to shape whereafter the patch is removed to be wrapped around the cigar filler, and the cycle is repeated. Instead of the pneumatic means comprising the holes 66 and transducer 90 for sensing the presence of a patch, dielectric or photo-electric means may be employed. The patches on the roll 32 may be cut to final size so that cutting at the station 14 is unnecessary. In a modification, the patches are spaced at regular intervals on the web 34 which has perforations coacting with sprockets in place of the roller 92, and control of the apparatus is governed by rotation of the sprockets.
