Patent GB-1050188-A (GB)
IPC: F02B37/013
Abstract: 1,050,188. Compressing and cooling air supply; exhaust gas turbine superchargers. SOCIETE D'EXPLOITATION DES MATERIELS HISPANOSUIZA. May 28, 1965 [June 9, 1964], No. 22780/65. Headings F1B and F1G. Combustion air from exhaust-driven superchargers 1-2 and 3-4 is further compressed in a compressor 7 and then [drives] expanded through a turbine 9, which in turn drives the compressor 7, before passing to a diesel engine M. The air is cooled in heat exchanges 5, 6 and 8. The exhaust gases are reheated in a combustion chamber 10 between superchargers. Fuel fed to the combustion chamber 10 from the engine fuel tank T is controlled by a valve 12 so that the ratio of the pressure of the air entering the engine to that of the exhaust gases leaving it is sufficient to ensure efficient scavenging. A valve 14 enables compressor 7, heat exchange 8 and turbine 9 to be by-passed. Should the pressure of the air leaving turbine 9 fall below atmospheric, a valve 15 automatically opens to supply air directly from the atmosphere to the engine.

Abstract: 1,230,203. Gas turbine plant and combustion chambers. M. ROMILO. Oct.30, 1968 [Oct.30 1967; March 15 1968] , No. 51447/68. Headings FIG; FIL and FIT. A rotary internal combustion engine comprises a fixed annular housing 111 surrounding a rotor formed by a toroidal wall 125 defining a chamber 127 containing generally tangentially directed combustion chambers 129. The wall 125 and combustion chambers 129 are secured to a shaft 119 having an internal passage 119C receiving air directly from atmosphere or from a compressor 121, which may be driven from shaft 119 by a belt 121B, the passage 119C communicating through ports 137 in the shaft with chamber 127. The combustion chambers 129 have convergentdivergent inlets 129B which receive air from chamber 127 for combustion with liquid fuel supplied through pipes 139, 145 to manifolds 147 on each combustion chamber. The combustion gases issue through nozzles 129C to rotate the rotor in the direction of arrow f 1 , the gases exhausting through outlets 113 in the housing 111. The outlets 113 may be connected to silencers. Each nozzle 129C is surrounded by a wall 133 to guide cooling air over the nozzle exterior from chamber 127. The fixed housing 111 may be double walled, as shown, having a space 111 B between the wall parts. Alternatively, fins or lagging may be provided on the exterior surface of the housing. Ignition in the combustion chamber 129 is effected by sparking plugs 149 or the like. In a modification, Fig. 9 (not shown), the combustion chambers 129 operate with intermittent combustion and each has within its air inlet 129B a valve (151) operated mechanically or by combustion chamber pressure. In this embodiment, curved vanes (137A) in the air inlet ports 137 in shaft 119 assist the guidance of air from passage 119C to chamber 127. In a further modification, Figs. 10, 11 (not shown), each combustion chamber 129 has lengthwise fins (155) and has a turbulence producing member (161A) mounted on a stem at its inlet. Figs. 1 to 6, (not shown), illustrate a slightly modified rotor and housing construction. The engine may be mounted directly on the axle of a motor vehicle.

Abstract: 1,238,973. Friction clutches. FICHTEL & SACHS A.G. 1 Oct., 1969 [3 Oct., 1968], No. 48259/69. Heading F2C. In a temperature responsive friction clutch for an engine cooling fan wherein a temperature responsive element 12 acts through a spring 4 rotatably fast with a clutch driven element 3 to expand friction pads 5 into engagement with a driving drum 1, excessive expansion of the temperature responsive element 12 due to overheating moves the element 12 left against the bias of springs 14 to prevent damage to the clutch. The temperature responsive element 12 is mounted in a sleeve 7 which is normally biased by the springs 14 to the position shown in which flanges 9 on the sleeve 7 abut a flange 6 fast with the driven clutch element 3. When the clutch is engaged further expansion of the element 12 overcomes the action of the springs 14 and moves the element 12 and sleeve 7 left to accommodate the expansion. Heat insulating washers 15, 16 are provided between the flanges 9, 6 and between the plunger 13 of the temperature responsive element and a cup which acts on the spring 4. A small vaned wheel conducts heat to the temperature responsive element 12 to improve sensitivity.

The arm 64 is rotatably mounted on a spindle secured to the support 20 and is biased to follow the roll periphery as the diameter decreases due to the unwinding of the tape. A stop 71 may be inserted in any of threaded holes 70 to prevent the following action when the roll becomes smaller than a selected diameter. Roller 68 is mounted on a spindle 65 which projects through an arcuate slot 66. The roller 68 and the core 58 of the tape roll when mounted on the hub 57 are spring biased in similar manner. Hub 57 is secured to support 20 (Fig. 7) and contains a cup 72. Spring 74, retained by pivot 73, urges the cup into frictional engagement with the hub 57 and a further spring 75 is affixed at one end to the base of the cup at 76. The other end of spring 75 projects radially outwards through a slot 78 behind one part of a mutilated flange 79. The core (58) (Fig. 5, not shown) of the roll bears two inwardly directed lugs co-operating bayonet fashion with the mutilated flange 79, one of said lugs engaging the radially projecting spring end to tension the spring when the roll is moved clockwise. On operation of the tape applicator the tape is drawn off the roll upon downward reciprocation of carriage 23 and the spring 77 is tensioned. Upon return of the carriage the spring 77 and the roller 68 tend to rotate the tape roll anticlockwise to take up the slack. Reference is made to Specification 1,309,430 wherein provision is made to remove a backing tape interliner from the adhesive tape. In an alternative machine wherein the applicator is adjustably mounted on a post the arm 64 is biased by a weight instead of a spring.

A flexible cable 14 is secured to the reed tip 2 and to a current carrying back stop member 16 to electrically shunt the reed 6. As shown, a plurality of ferromagnetic backing springs 20, 21, 22 are provided for reed 6. The enclosure comprises metal ends 9 and 10 and an insulating centre section 11. To protect the glass insulating section 11 from splashes of molten contact material the metal end 9 may be extended to the region of the contacts 2, 3 and the insulating section 11 is provided with re-entrant portions. A multipole contactor has a single operating winding controlling a plurality of such reed switches. In Figs. 15 and 16, not shown, each pole of a multipole contactor has a main reed switch whose contacts are in parallel with two auxiliary reed switches. Mounted on the flux guide member of each auxiliary reed switch is a holding coil in series with its contacts. In series with the two auxiliary contact sets are oppositely poled rectifiers. The operating coils of the three reed switches are in series so that on de-energization the main contact set opens first followed by the slower acting auxiliary reed switches. According to the polarity of the supply on de-energization one or other of the diodes will be out off and its associated reed switch will open. The remaining reed switch is retained by its holding coil until the current approaches zero whereupon it will open.
