Filed: 1958-07-07
Abstract: 890,839. Valves. ROBERTSHAW-FULTON CONTROLS CO. July 7, 1958, No. 21716/58 Class 135. A thermostatically-operated valve for an engine cooling system comprises a sleeve-type valve member 78 actuated by a wax-fusion type thermostat 38, carried by a perforated member or spider 22. The member 22 also provides the valve seat 26. The valve member 78 is open at its lower end and is provided at its upper end with a plurality of sector-shaped ports 82, which define a number of inwardly-extending arms 84 terminating in a centrally-disposed hub 86 having an aperture 88 extending therethrough. The thermostat 38 is surrounded by a close-fitting sleeve 46 loaded against the thermostat piston 45 by a spring 64. The sleeve is also provided with a stem 54 threaded at 66 to receive an adjustable member 68, the underside of which is abutted by the hub 86 which is retained in engagement therewith by a spring 90. When the coolant temperature is low the valve member 78 is in the position shown and fluid flows through the ports 82 to the main conduit 18. With an increase in temperature the piston 45 is forced upwards by the thermostat and causes the closure member 78 to move progressively away from its seat 26 to permit fluid to flow through the conduit 16. In its uppermost position the valve member seats on the conduit wall 92 and completely cuts off flow through the main conduit 18. The temperature at which the valve member commences to move away from its seat is selected by rotation of the member 68, which varies the loading of the spring 64. Due to the open cylindrical shape of the valve member it is not affected by pressure of the fluid controlled by the valve.

Convention date, Nov. 7, 1929. [Class 7 (v).] In a Diesel or other engine which is started without compression, and in which the exhaust valve is subsequently brought automatically into normal operation by means of a pin 3 in engagement with a screwthread 2 or a spiral groove in an engine-driven member, the pin 3 is coupled in such a manner with a rotatable toothed segment 6 or like member operated by the pin, that the planes of oscillation of the pin and the segment 6 are at right-angles, a spring 10 being provided to effect the return movement of the pin. As shown, the pin 3 is carried by a lever 4 pivoted on the segment 6 and acted upon by the torsion spring 10 on the pivot. The segment 6 is rotatable on a shaft 5 at rightangles to the pivot of the lever 4, and engages a pinion 7 carrying a lever 8 connected by a rod 9 to means for operating the exhaust valves. At starting, the segment 6 is moved about the shaft 5 to bring the pin 3 into engagement with the lowest portion of the conical screw 2, by means of a crank handle on the shaft of the pinion 7, and the rod 9 effects opening of the exhaust valves. Upon rotation of the shaft 1, the screw 2 moves the pin 3 outwards from the shaft, turning the segment 6 and bringing the exhaust valves gradually into normal operation. When the pin 3 leaves the screw 2, the spring 10 moves the lever 4 and pin 3 axially of the shaft 1 into the initial position, adjacent to but out of engagement with the lowest portion of the conical screw. The conical screw 2 may be replaced by a plate having a spiral groove, the last turn of which is above the surface of the plate.

Abstract: 1351517 Optical projection apparatus AGFAGEVAERT A G 19 April 1971 [17 Feb 1970] 21984/71 Heading G2J  A device for masking the picture gate of a slide projector during slide changing includes a slide carriage mechanism and a mask which is removed from a masking position in response to a movement of the mechanism after the slide is finally positioned in its projection position. Masking of the picture gate also occurs prior to removal of the slide from the projection position. As shown in Fig. 1 a slide changer 2 moves a slide 5 from a magazine 3 to align with picture gate 4. When the slide 5 is in the position shown stop 6b prevents further movement of the arm 6 and relative movement between the changer 2 and arm 6 is then permitted by the pin/slot connection. In further movement of the changer 2, projection 2c abuts stop 12c and pivots the assembly 12 about the shaft 13 so that arm 12c strikes point 8a and removes mask 8 from the picture gate 4. Reversal of the movement of changer 2 causes the mask 8 to return to the picture gate 4, as shown, and then causes the arm 2b to return the slide 5 to the magazine. In a modification, Fig. 3, (not shown), of this embodiment the further movement of the changer 2 closes electric contacts (39) to power an electromagnet or motor to move the mask.

Title: Improvements relating to the control of power operated switch machines
IPC: B61L21/06
Filed: 1929-07-18
Abstract: 315,804. General Railway Signal Co., (Assignees of Wight, S. N.). July 18, 1928, [Convention date]. Electric operation and control. - Pointsmachine, of the kind described in Specification 169,795, are de-energized by a time-lag switch, at a predetermined time-interval or on the passage of an excessive current through the machine, independent of the completion of the operation. In the former case, the carrier for the contacts 10,. 11 of the machine is connected by an arm 13, biassed to the neutral position, to a slotted link 14 which actuates two mercury switches 15, 16 each having an apertured partition to enable the mercury to leak away and open the contacts. These switches are in the return circuits common to the main, holding, and restoring coils NC, NC<1>, NC<3> or RC, RC<1>, RC<2> for the contacts 10, 11. In operation, the cabin lever L energizes the relay Z to close contact 22 and direct contact 24 to either coils NC or RC. Contact 10 then completes the circuit for the corresponding holding-on coil. The operation can be reversed before completion since the restoring coil on one side is in parallel with the main coil on the other side. The return circuits through leads 42, 28 and switches 15, 16 are however broken when sufficient mercury has passed the partition, and the bias spring 12 restores the contacts 10, 11 to neutral position. In an alternative form, the holding and restoring coils and the mercury switches are dispensed with, and a thermal switch is placed in the return circuit C from the points-machine SM or its controller SMC, so as to break the circuit of a relay which connects the power B to the contact 22. This relay can be re-energized by a detector relay DR or by a push-button in a locked casing near the points. This relay may also perform the approach-locking, if used.

Abstract: 865,514. Aircraft. FOWLER, H. D. June 26,1959, No. 22115/59. Class 4. An aircraft having a wing and a turbo-jet engine or a propeller developing a slipstream, comprises a flexible curtain on a roller located rear-wardly of and below the wing, and extendable into the slipstream to deflect a part thereof downwardly to develop vertical lift and equalize drag and thrust. The aircraft shown is a biplane having on each side of the fuselage wings 10, 11 connected at their outboard ends by a plate 12 extending below wing 11. A streamlined strut 28 extends from the fuselage to the plate. Wing 10 has an extension flap 13 adapted to close the gap between the wing and the strut. Wing 11 has a flap 14 and a slotted auxiliary flap 15. The strut 28, Fig. 4, contains a roller 29 on which is wound a curtain 27 of reinforced rubber, nylon sheet, or thin stainless steel, the roller being spring biased to tend to wind in the curtain. The free end of the curtain is attached to a rod 30, extending between the reciprocable parts 47, 48, Fig. 5, of screw jacks 40, 41 mounted in plate 12 and the fuselage respectively. The screw jacks are interconnected by a shaft 33, Fig. 4, and driven by a motor 45, Fig. 5 controlled manualy. To provide vertical lift, the flaps 13, 14 and 15 are moved to their extended positions, and the curtain is wound off the roller by the motor 45. Instead of relying on the spring biased roller to maintain the curtain taut, the unwinding of the roller may be controlled by motor 45. The propellers 22, 23, one each side of the fuselage, are each driven by a gas turbine engine, and are staggered longitudinally, the propeller discs overlapping and together extending across the entire wing span. The distance between the extended curtain and the extended flaps 14 and 15 should be equal to the distance between the two wings. The aircraft has upper and lower rudders 5, 6, and an external fuel tank 25.
