Title: Vibration-responsive control system
IPC: H02H5/00
Filed: 1960-06-30
Abstract: 947,316. Fluid-pressure servomotor systems. WESTINGHOUSE AIR BRAKE CO. June 30,1960 [July 3, 1959], No. 22953/60. Heading G3P. [Also in Divisions F2 and H2] A control system for shutting down an engine or motor upon excessive vibrations caused by the engine or motor, includes a vibration responsive device having a structure 15 adapted to be rigidly connected to a part susceptible to engine or motor vibrations, said structure including a bearing 9, 10 from which is suspended a pendulum-like assembly 5, displaceable from a normal position only when vibrations of said part exceed a predetermined level; a control means, including a valve member 21 engaging, in a normal position, the pendulumlike assembly in its normal position, and supplying control fluid under pressure to a chamber 37 to prevent actuation of the control means, the valve member being urged toward the pendulum-like assembly so that displacement of the latter from its normal position permits movement of the valve member to an abnormal position in which it interrupts the control fluid supply to and vents said chamber to actuate the control means and cause or initiate the shut down of the engine or motor. Pressure fluid is supplied to the valve 21 through a line 64 to maintain the piston actuator 4 in operative position through a line 38, disturbance of the pendulum 5 allowing the valve 21 to rise under the fluid pressure and vent the actuator to atmosphere at 28 so that it rises and breaks a switch 41, 47, 48 in the circuit of an electric motor 3 in the event of excessive vibration of the motor which is rigidly connected to the structure 15. The system is set initially by a manual valve 55 which on depression allows pressure fluid from a source 46 to flow through one side of a shuttle valve 63 to the control valve 21. The actuator piston constitutes a spool valve 35 which on attainment of its operative position establishes communication between the source 46 and the other side of the shuttle valve 63, whereupon the manual valve 55 may be released. In its operative position, the piston spool valve 35 vents a line 64 to atmosphere at 43 to prevent any fluid being trapped. In an alternative embodiment, the actuator operates a main valve adapted to control, e.g. the supply of fuel or motive fluid to a prime mover which is to be stopped in the event of excessive vibration.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 12, 1935]. Drawings to Specification. [Class 98 (ii)] In the reproduction of opaque originals by reflex contact printing, the light is passed before its passage through the sensitive layer through a. dividing screen which subdivides it into small beams of greater actinic intensity separated by regions of less actinic intensity and the sensitive layer is so adjusted with respect to the dividing screen so as to make the intersection space of the beams of greater actinic intensity with the sensitive layer relatively small. A lenticular dividing screen with a high ratio between the focal length of the lenses and the thickness of the sensitive layer may be employed. A punctiform, linear, or band like source of light may be used. The system to be illuminated may have the form of a circular cylinder, or may be moved in the surface of a circular cylinder in the axis of which the source of light is located. The sensitive material may comprise transparent foil, such as celluloid, sensitized on both sides or through the entire mass with paradiazodiphenylamine, which is developed with an alkaline solution of an azo coupling component, or may be sensitized with fine-grained silver bromide emulsion.

Title: Improvements in kinematograph positive films with sound and picture records, and methods of producing same
IPC: G03C5/14
Filed: 1932-08-19
Abstract: 406,031. Combined sound and picture films. THORNTON, J. E., 8, Hill Street, Jersey, Channel Islands. Aug. 19, 1932, Nos. 23250 and 24895. [Class 40 (ii).] Relates to processes for producing combined sound record and colour-picture positives, wherein both records are first printed upon a film sensitized with silver salts, which film is developed, and the deposited silver then bleached by a reagent which renders insoluble the gelatine or similar colloid in proportion to the quantity of silver in contact therewith. According to the invention, which is applicable to the production of films of various kinds in which the pictures are in one, two, or more colours, the bleached silver of the sound record is finally changed into black or other sufficiently opaque colour, and the bleached silver of the pictures is changed into transparent coloured pictures, such changes being effected by separate independent treatment of the two records without protecting either of them with a varnish or other waterproofing layer. The bleached sound record image may be turned into a black one either by means of one or more dyes or staining agents, or by the action of a developing agent ; in either case, the bleached picture images are dyed or toned by any usual process. The simultaneous application of the different dyes to the sound and picture tracks respectively may be effected by any known means, for example by means of ductor rollers. The invention may be applied to the production of non-relief positives in which the parts of the images to be coloured are composed of soft gelatine and are dyed by the imbibition process with dyes of the pinatype class. It may also be applied in producing films on which the sound and picture images are formed in relief in hardened gelatine, which absorbs dye or staining solution in proportion to its varying thickness.

Title: New or improved adjustable pivot attachment for pivotally mounted or swinging mirrors, pier glasses, toilet glasses and the like
IPC: A47G1/24
Filed: 1921-09-01
Abstract: 187,403. Cowie, F. Sept. 1, 1921. Pivoting - adjustments for swinging mirrors. The pivoting screws are adapted to be fixed relatively to the supporting posts when they have been screwed up to give the mirror a sufficiently stiff movement, so that subsequent turning of the mirror will not loosen or tighten them. The pivoting screw D which passes through the supporting post A and screws into a nut in the framing B of the mirror, is provided with a handle F to which is fixed a radially-slotted metal disc E. To the outer side or the post A, and adapted to engage with this disc, is fixed a plate C out of which is pressed a spring pawl I with finger-piece K. Both the disc E and plate C may be fixed to the wood by triangular tags G pressed up out of them, and the plate C has a peripheral flange H to prevent the spring pawl being jammed. In action the screw is inserted through the post and frame and, with the finger-piece K pressed against the post, the screw is tightened until sufficient pressure is exerted between the post and frame; the fingerpiece is then released to engage the pawl with one of the radial slots, fixing the pivoting screw relatively to the post. Figs. 5 and 6 show another form in which a pivoted pawl O on a plate T fixed to the post engages with a cogwheel U fixed to the screw-head, the pawl being lifted by hand when tightening the screw. In both these forms the parts may be so constructed that the pawl rides over the cogs or slots while tightening the screw. the friction between the surfaces being sufficiently great to prevent this happening when the mirror is turned.

One end of the bolt 1 is fixed to one end of a leaf spring 5 which has an intermediate portion positioned obliquely with respect to the front of the cabinet and to a side of the cabinet with which the other end of the spring 5 extends parallel thereto. The other end of the spring 5 slides in a groove in a bearing 6. A shaft 7 is axially supported in the bearing 6 by a pin 8 which is passed through said other end of the spring and diametrically through the shaft 7. The latter is radially supported by plain bearings 9 which are secured to the cabinet 3 and carries catches 11 which, along with respective spring sliders (not shown) on each drawer, release or retain captive the drawers when fully inserted into the cabinet and the locking mechanism is locked, the bolt 1 being moved into the sleeve 2 under the action of the key. When the bolt 1, released by the key, projects from the sleeve under the action of an inner spring, this movement is communicated to the spring 5 which then pulls on the projecting end of the pin 8, the latter rotating the shaft 7 so that the catches 11 are moved out of the path of the spring sliders which are thus released.

Abstract: 1528689 Borehole logging MOBIL OIL CORP 7 June 1976 [25 June 1975] 23366/76 Heading G1A In a system for logging the formations traversed by a borehole, a suspended borehole tool 10 containing a steady state source 11 of fast neutrons irradiates the surrounding strata. The secondary re-radiated radiation is investigated by two pairs of spaced detectors 12 and 13, 14 and 15 positioned and constructed to detect respectively thermal neutrons and epithermal neutrons. A shield 43 protects the thermal neutron detectors 12 and 13 from direct neutron radiation from the neutron source 11. The detector outputs are amplified 19, 20, 21 and 22 and passed up the cable 47 to ratio detectors 41, 42 via slip rings and brushes 27, further amplifiers 33, 34, 35 and 36 and count rate meters 37, 38, 39 and 40. One ratio detector 41 is for the thermal neutrons, the other 42 is for the epithermal neutrons. The thermal neutron's counting rate increases when the strata formation fluid changes from oil to salt water but the epithermal neutron counting rate ratio remains unchanged. Coupled to the outputs of ratio detectors 41 and 42 is a recorder 44. The recorder may be a trace recorder having its chart driven continuously in correlation with depth by way of mechanical connection 45 and measuring reel 46 coupled to cable 47. Furthermore both ratio detectors 41 and 42 may be applied to a comparator 53 which is calibrated to provide an output signal representative of oil saturation.
