Title: Optical method for measuring the separation between relatively movable objects
IPC: G01B9/02
Filed: 1965-04-27
Abstract: 1,094,392. Optical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 27, 1965 [April 29, 1964], No.17600/65. Heading G2J. A method of measuring the spacing between two relatively moving objects 10, 11, one of which is transparent and the other reflective, comprises the steps of illuminating the objects by directing a beam of light containing at least two frequencies through the transparent object 10 on to the reflective object 11 so that light reflected from the object 11 interferes with light reflected from the object 10, projecting the resulting interference patterns on to display or recording means, and comparing the patterns for the two frequencies of light to determine the spacing of the objects. Light from a source 12, which may be a flashlamp, is directed through a lens system 18 of a camera on to the objects 10, 11, and the reflected light from the objects returns through the lens system 18 to a series of dichroic mirrors 22 which separate the reflected light into red, blue and green components. Each component of the light then passes through an associated filter 21 to a photographic film housed in a holder 20. Thus, the interference will coincide exactly wherever the spacing of the two objects is a multiple of the three half wavelengths of the red, blue and green light. In another embodiment Fig. 4 (not shown) the objects are illuminated by a beam of light having two zones of different colours one on each side of a fine dividing line. The camera then records a two part interference pattern in which fringes which are continuous over the whole map provide an indication of the required measurement.

Title: Improvements in and relating to the control of mixed power installations
IPC: H02P9/00
Filed: 1932-06-22
Abstract: 403,680. Control of D.C. motors ; actuating controllers. SACCAGGIO, P. C., El Chalet, Remedios de Escalada, Ferrocarril del Sud, Buenos Aires. June 22, 1932, No. 17682. [Class 38 (iii).] In mixed power installations such as on locomotives etc., where a prime mover drives a generator which supplies a load, e.g. motors in a Ward-Leonard system, upon operation of a starting handle R, R<1> a regulator resistance SS is automatically moved in one direction at a predetermined rate to increase the excitation gradually, load responsive means Z being provided solely for arresting the regulator SS when the load reaches a predetermined limit and additional load sensitive means M, P being provided to return the regulator to its initial position at a more rapid rate when the load exceeds a predetermined abnormal limit. The generator field rheostat SS is controlled by a piston E in oil, one side of the piston being connected to a chamber B and the other through a restricted pipe K and shut off valves Y, Z to a chamber C, a magnetically operated slide valve M being provided to admit atmospheric and vacuum pressure to the chamber B and C alternatively to cause movement of the piston E in either direction. Closure of the contacts R, energizes a solenoid P to admit atmospheric pressure to the chamber B and low pressure from a pipe 0 to the chamber C thereby-to move piston E from left to right at a rate predetermined by the dimensions of the pipe K so as to cut out resistance sections cc at a predetermined rate. On the attainment of a normal load limit on the prime mover load sensitive means such as the speed and fuel governor J operate to close valve Z and arrest movement of the piston E either temporarily or permanently. The movement may be arrested at any time by closure of the valve Y by energization of a solenoid U by a switch V. Abnormal overload of the prime mover closes contacts c on the governor arm PP and opens a magnetic switch a in the circuit of the solenoid P thereby allowing spring S to return the valve M and admit low pressure to chamber B and atmospheric pressure to chamber C to cause reverse movement of the piston E. A non-return valve GG by-passing the pipe K allows of quick return of the piston E. Instead of vacuum control, compressed air control may be used in which case the ports of the valve M are reversed. The valve Z may be operated from a wattmeter relay connected in the generator circuit and the piston E may be replaced by a rotating vane in a cylinder, opposite sides of the vane being connected to chamber B and through a pipe K to chamber C respectively.

Title: Apparatus for bringing ribbon-type media together
IPC: G03B1/48
Filed: 1963-05-06
Abstract: 982,480. Bearings. FMA Inc. May 6, 1963 [Feb. 25, 1963], No. 17838/63. Heading F2A. [Also in Divisions B6 and G2] Two ribbon-like media (e.g. film strips) are progressed, pressed together in close contact, through a region between a pair of facing closely-spaced platens, the platens having similar arrangements of orifices registering with each other, through which air is blown normally on to the films, so that as the film strips are pulled between the platens they are supported by a cushion of air between film and platen on each side. Fig. 2 shows a photographic printing apparatus, in which the negative film 34a unrolls from supply reel 35a on to take-up reel 36a, and the positive film unrolls from supply cassette 35b to take-up cassette 36b. At the exposure station, the films pass in contact between two air platens 32a and 32b according to the invention. Each platen contains a series of orifices through which air is blown, so that the two films are pressed into close contact by a cushion of air on each side. The orifices in the two platens are disposed in identical arrangement, in register with each other, and direct the air normally against the films. The contact is such that one film will pull the other along, i.e. only one film requires to be driven. A typical spacing between the platens is 0.013 inch; with a combined film thickness of 0.011 inch this leaves 0.001 inch clearance on each side between film and platen, so that the films are conveyed without coming into contact therewith. The air supplied to the platens is previously passed through a series of filtering and regulating stages (Fig. 1, not shown). Besides the air platens, the air is also supplied to a number of air bearings (Fig. 2), the films passing round the bearings on a cushion of air, which is equivalent to passing over rollers. The construction of the air platens themselves is shown in more detail in Figs. 4, 6 and 7. The air orifices 46 are arranged in a series of rows, the rows being separated by slots 45. Some of the orifices open into a series of recesses 47a, 47b &c. formed in the platen, in order to provide a more uniform distribution of the air pressure.
