IPC: G02B21/00
Filed: 1951-09-18
Abstract: 727,899. Optical - projection apparatus. REASON, R. E., ADAMS, J. R., COLEMAN, K. R., and KAPELLA, Ltd. Sept. 11, 1952 [Sept. 18, 1951], No. 21847/51. Class 97 (1). [Also in Group XIX] For simultaneously projecting on to a single image plane images of profiles of two or more plane sections parallel to, but at different distances from the image plane, one or more plane reflectors associated with individual sections are located to produce reflected images of the sections in a single object plane and an objective forms an image of that plane in the image plane. As shown in Fig. 1, a section A<SP>2</SP>, of an object A, is defined by illuminators D, D<SP>1</SP>, each having a lamp D<SP>4</SP>, a condenser D<SP>5</SP>, a mask D<SP>6</SP> and a lens D<SP>7</SP> for producing an image of the mask on the object. A plane A<SP>3</SP> is similarly defined by illuminators D<SP>2</SP>, D<SP>3</SP> and an image of it is produced by a mirror G in the plane of the section A<SP>2</SP>, an image of which plane is produced by the objective F. The mirror G is annular and the light from the section A<SP>2</SP> passes between the mirror and the object to the objective. Alternatively, the mirror may be partially reflecting and fit the object more closely. When the object is of helical form, such as a turbine blade, it may be guided during insertion by engagement of a helical slot B<SP>1</SP> on the object holder, with a fixed pin B<SP>2</SP>. Three or more sections may be projected simultaneously using two or more mirrors of different reflecting powers, when partially reflecting, or having apertures of different sizes when opaque, the reflecting powers or aperture sizes being chosen to give equal image intensities. Fig. 13 shows a mirror, formed in sectors N, instead of being annular as in Fig. 1. To permit insertion of the object the sectors are simultaneously radially adjustable, against springs N<SP>2</SP>, by cam surfaces P<SP>2</SP> on a rotatable ring P. To accommodate objects of different sizes the reflectors may be exchangeable as a unit or individually in which latter case their mountings are axially adjustable.

Title: Improvements in or relating to voltage stabilizing systems
IPC: G05F1/33
Filed: 1950-09-06
Abstract: 707,878. Magnetic amplifiers. AUTO. MATIC ELECTRIC LABORATORIES, Inc. Sept. 6, 1950 [Sept. 6, 1949], No. 21957/50. Class 40 (4) [Also in Group XXXV] In a voltage control system as disclosed in Specification 633,840 (in which a cascaded magnetic amplifier 13, 14, 15, 16, controls a saturable reactor 10 in series with the A.C. input to a rectifier) an additional winding 10d is provided on the reactor 10 and is connected in series with the control winding 15c of the amplifier reactor 15. Any change in the current in the control winding 10b causes a  voltage to be induced in winding 10d in such a sense as to oppose the corresponding change in current in the winding 15c and thus improve the stability. Also, due to distortion of the flux wave form as the saturation of the core of reactor 10 is increased, the second harmonic of the magnetic flux due to the A.C. windings links with the winding 10d and the voltage induced, when rectified by rectifier 19, assists the control current in winding 15c and increases the sensitivity of the amplifier.

Patent GB-222932-A (GB)
Abstract: 222,932. Haddan, R., (Postage Meters & Machines Co.). July 6, 1923. Franking-machines.-A meter has a series of changeable dies adapted to be used on postal franking-machines such as described in Specification 170,058, and any one of the dies may be mounted in position in the meter to operate registering-mechanism proportionatelv to the value of the denomination of the die employed. The removable die 312, Fig. 3, is at its upper end positioned by a half-bearing 301<f> in a bracket 301<a> and journaled in a bearing 302b which is carried by a movable bracket 302. At its lower end it engages by projections 312<x>, 312<c>, and 312<g> with corresponding holes in a die carrier 311. The projection 312<x> is in alignment with a shaft portion 312<a> which carries a pinion 312<b> for gearing with its corresponding gear 308<a> of a conical series of gears on a shaft 308 which drives the registering- mechanism. The shaft 308 and die carrier 311, Figs. 3 and 5, are mounted on a hollow base 301 closed by a sliding plate 304 and spring catch 305. The shaft 308 and die carrier 311 are prevented from rotation in the wrong direction by detents 314 and 315 respectively and are prevented from being operated when the meter is removed from the machine by a pivoted member 66 which is provided with lugs 66<a>, 66<b> for engagement with recesses in a cam 313<b> and ratchet wheel 311<b> respectively. The member 66 is acted on by a spring 68 but is prevented from moving to its locking position by the engagement of a pin 17 with a pin 69<b> having an enlarged portion 69 and a portion 69<a> surrounded by a spring bearing against the pivoted member 66. The registering- mechanism is contained in a sealed casing and comprises two counters one indicating the total amount used up and the other the balance remaining. The counters are both driven from a wheel 310<a> on a shaft 310 driven by bevel and spur gearing from the shaft 308. The counters are preferably such as described in Specifications 221,904 and 222,929. A locking-plate 321 is provided with teeth 321<a> to engage locking-discs on certain of the " balance " counter wheels when at zero. The locking-plate is provided with a second plate 321b capable of being operated by hand to move the locking-plate when setting the meter. This second plate is provided with a lug obstructing the movement of a pivoted lever 322 connected by a link 324 to a spring-pressed bellcrank 323. When the meter is discharged the bell-crank 323 moves under spring action and engages by a lug 323<b> with a slot in the cam 311<c> of the die carrier 311 and by a lug 323<c> with a ratchet wheel on the shaft 308 to lock the die carrier and shaft 308. This movement of the bell-crank 323 allows a second spring-pressed lever 325 to move downward and move an aperture in its free end 325<b> from registering with a hole 301<c> on the casing. Thereby a pin 8 is prevented from projecting through the meter casing which, as described in Specification 170,058, is necessary for the functioning of the clutch member of the die carrier.
