Title: Improvements in or relating to electric switches having manual and automatic operation
IPC: H01H71/50
Filed: 1952-09-19
Abstract: 709,173. Switches, partly electromagnetic; mechanical switches. OFFICINE ELETTROMECC F. RAPIZZI & F. DI GAETANO RAPIZZI. Sept. 19, 1952 [Sept. 29, 1951], No. 23630/52. Class 38(5) In a switch having slow manual opening, electromagnetic opening in response to overload, and quick closure under the bias of a spring 6, a contact-carrying lever 3 is opened on overload by the core 11 of a solenoid 9 through the medium of a bar 10 which has a wedge-like profile 10<SP>1</SP> of a constant inclination such that the gap between the contacts 4, 5 when opened varies linearly with respect to the overload current in the solenoid coil. When the bar 10 has opened the contacts by engaging with the tail 3<SP>11</SP> of the lever 3 and turning the lever about its fixed pivot 7, Fig. 3, the tail prevents the return of the bar 10 when the solenoid 9 is de-energized by the opening of the contacts 4, 5, and the lever 3 is held in the opened position. To reset the switch, the end 2<SP>1</SP> of a bar 2 is depressed so that a portion of the bar 2 engages a tongue 3<SP>1</SP> pressed out of the lever 3 and turns the lever further so that the tail 3<SP>11</SP> releases the bar 10 which falls down to its initial position. The end 2<SP>1</SP> of the bar 2 is then moved back again so that the spring 6 is able to reclose the contacts, the various parts of the switch then occupying the positions shown in Fig. 1. The switch is opened manually by depressing the bar 2, which in a multipole switch may be a common member interconnecting the various switch units. A blade spring 12 damps any vibration of the lever 3 and assists the spring 6 in reclosing the contacts. The distance the contacts are opened on overload depends on the amount by which the bar 10 is raised by the core 11 of the solenoid, i.e. on the overload current.

[Also in Divisions E1 and G23] Exhaust gases from the engine of a front-end loading mining machine pass to the exhaust manifold via control units 16 (only one is shown) arranged in parallel and incorporating water spray nozzles (19). Each unit also includes a thermally responsive pilot valve, and air from receiver 27 passes in series through the pilot valves to line 25 having a fixed bleed 33 and acts via lines 28, 31 to maintain air and fuel valves 32, 29 open. Upon closure of one or more of the pilot valves due to excessive exhaust temperatures, pressure in lines 28, 31 falls and valves 32, 29 close. Check valves 38, 41 with by-pass restrictors 34, 36 ensure that the final valve opens after and closes before the air valve. The pilot valves can each comprise a passage within and responsive to expansion of the body of a unit 16, or it can comprise a snap diaphragm closure in the passage. Valves 29, 32 include actuating diaphragms (54), lift closures (49) and spring diaphragms (53), the latter including manual actuator (59). Valves 29, 32 can be operated by relay valves. In the modification of Fig.7 air from receiver 27 passes serially through pilot valves 62, each having a thermal bulb sensing exhaust temperature in one limb of the exhaust system, and acts via fluid diodes 71 on pilot valves 73 causing the latter to admit higher pressure air from 75 to air and fuel valves 72. Excess exhaust temperatures cause one or more of the pilot valves to vent line 25 to close the valves 72.

Abstract: 240,501. Marks, E. C. R., (Peoples Savings & Trust Co. of Pittsburgh). March 25, 1924. Jet condensers; progressive evaporators; separate heater and evaporator apparatus.- Relates to non- rotary apparatus for the centrifugal treatment of fluids, and its applications include separating, condensing, and distilling. The liquid or gas to be treated is led from a space A, Fig. 1, through a ring of long, narrow, overlapping blades d, Fig. 2, which give it a whirling movement in the space D. The contained solids or heavier components are reeetived by the fixed bowl G and discharged through a tangential duct H, while the lighter constituents are delivered through an outlet C in a cover I, the opening C having a smaller diameter than the bowl G. Fig. 27 shows four superimposed units acting as a jet condenser with pipes 144, 145 for admitting steam and condensing water respectively. Water is expelled through an opening 152 in the bowl 150, exhaust air through a pipe 146, and any separated oil is discharged through a cone 155 and pipe 156. For distilling liquids, a unit with a closed casing is used, the liquid being introduced at a high temperature and pressure in the form of a jet which vaporizes, the vapour being freed from solids as already described. For distilling petroleum oils, steam may be used to pick up a shower of oil in the devices, and to carry off the lighter vaporized constituents of the oil, the oil residue being centrifugally discharged from the bowl and passed to the next centrifugal unit. Specifications 24253/06, 6206/12, and 203,395, [Class 23, Centrifugal machines &c.], are referred to.

Abstract: 750,921. Photographic shutters. SOC. D'ETUDES DE MATERIEL PHOTOGRAPHIQUE. Sept. 1, 1953. [Oct. 17, 1952], No. 24108/53. Classes 97 (1) and 98 (1). A camera shutter comprising two partcylindrical members rotatable about a common axis parallel to the light-sensitive layer to be exposed and intersecting the camera optical axis to form between said layer and the object to be photographed two diametrally opposed exposure slots parallel to said common axis, is characterized in that the slots are formed between the bounding generatrices of these members, one of which is of slightly smaller radius then the other to allow overlapping, and a disc or plate rotatable about an axis transverse thereto and parallel but not coincident with the said common axis of the said members is provided with two radial guiding slots in which are slidably engaged pins fixed parallel to said common axis on said members, one of which is directly rotated one revolution for each exposure, the bounding light-sensitive layer narrower than that nearer the camera objective. As shown, cylindrical arcuate surfaces 1, 2 are secured concentrically to circular sectors 3, 4 themselves concentrically mounted on a common pivot 5 on a fixed arm, the surface 2 being of smaller radius than the surface 1. Secured to each of the sectors 3, 4 is a pin 18 or 19 engaging in slots 16, 17 along a diameter of a disc 14 concentrically mounted on a pivot 15 on a stationary adjustable rod 22, the pivots 5, 15 being spaced along the line of the optical axis: Starting from the closed position shown in Fig. 3 pin 19 and hence the shutter member 2 travels faster than the shutter member 1 so that a second slot is formed between them until the pins 18, 19 have changed places as shown in Fig. 1 when the slot nearer the film 13 is smaller than the front slot. Thereafter the relative motion of the pins is reversed so that the member 1 catches up the member 2 to close the shutter in the Fig. 3 position again. To vary the opening of the rear slot at the time of exposure, the pivot 15 is movable along the optical axis by an adjustment screw 23 secured to the rod 22. The shutter is driven by a toothed ring 20 on the sector 3 engaged by a pinion 21 which may be connected to the film feeding means so that a frame is fed for every revolution of the shutter members, i.e. for every exposure.
