Title: Improvements in and relating to photography
IPC: G03C5/08
Filed: 1938-04-20
Abstract: 513,793. Photographic projection-printing apparatus. PHOTO-CYLINDER CORPORATION. April 20, 1938, No. 11831. Convention date, June 3, 1937. [Class 98 (i)] To prepare a design, an image is projected upon a light-sensitive surface and the relative positions of the design image and light-sensitive surface are changed during exposure by moving the design in its own plane. The design is supported on a movable h'older located in front of a process camera. As shown, the copy board 17 to which the positive or negative of a design is secured carries a back plate 30 having pins 31 engaging enlarged apertures 34 in a frame 16. The plate 30 is also engaged by two pins eccentrically mounted on shafts 35, 36 respectively, the eccentricity being adjustable and the two shafts being drawn together by shaft 47. 49, 51 from a motor 44 so that the copy board describes a circular path during exposure. To permit an additional lateral movement during exposure, the frame 16 is mounted on rollers 64, 65 engaging the girder 67 and carries a boss 80 engaged by a worm screw 79 on a shaft 75 having an adjusting handle 78 movable between two stops 81, 82 adjustable by rotating a screw threaded rod 83. The handle 78 is normally held between the stops 81, 82 as shown in Fig. 3, but for the additional movement the stops are adjusted to the dotted position and the shaft 75 rotated to move the frame 16.

Title: Apparatus for adjusting control members of axial flow machines
Inventor: ARSCOTT WILLIAM HAMMETT
IPC: F04D27/02
Filed: 1960-04-04
Abstract: 944,868. Fluid-pressure servomotor control systems. DE HAVILLAND ENGINE CO. Ltd., and DOWTY FUEL SYSTEMS Ltd. April 4,1960, No. 11854/60. Heading G3P. [Also in Division F1] An apparatus for adjusting the inlet guide vanes of an axial flow compressor, for example the compressor of a gas turbine engine, comprises a member 23 pivoted at 24 and carrying a control valve 22. Centrifugal weights 40, driven from the rotor apply a force proportional to speed in one direction to the member 23 while a temperature responsive means 50, subject to the temperature at a selected point of the machine, such as the inlet, applies a force in the opposite direction. The member 23 is also subjected to a balancing force through a spring 52 which is initially adjustable manually by a screw 61. The vanes 9, or other control member of the machine, are adjusted by pistons 1 through bell crank levers 7. The right hand side of the pistons 1 are subjected to a constant pressure supplied through a line 12 while the left hand side of the pistons are subjected to a variable pressure in the line 16. A line 17 receives the supply pressure through an orifice 18 and a branch line 21 containing an orifice 20 leads to a nozzle controlled by the valve 22. The pressure in the line 16 is maintained proportional to the variable pressure in the line 21 by a valve 25 comprising a diaphragm 26 subjected on one side to the pressure in line 21 and a spring loading 28 and on the other side to the pressure in the line 17 such that a valve 29 controls leakage from the line 17 to maintain the proportional pressure in the line and hence in the line 16. Such an arrangement provides rapid movements of the piston 1 in response to movements of the valve 22. In operation a variation in speed or temperature acts on the member 23 to operate the valve 22 which varies the leak from and hence the pressure in the line 21. The pressure in line 17 varies accordingly and the vanes are adjusted. Movement of the vanes acts through levers 58, 57 to rotate a wheel 56, meshing with a sleeve 54, causing adjustment in the balance spring loading 52 in a sense to restore the balance between the forces acting on the member 23.

Title: Improvements to spectroscopes
IPC: G01J3/14
Filed: 1925-05-08
Abstract: 248,960. Beck, C. J., and Beck, Ltd., R. & J. May 8, 1925. Spectroscopes; prisms. - An image of the slit used for producing the spectrum is utilized to form an index with respect to which the spectrum can be moved in order to register the position of a line or band. The. slit A is placed in the focus of a collimating lens B, and behind this lens is situated a compound prism C provided with a diffraction grating. The surface C' of the prism C is coated with a diffraction grating or the grating may be ruled on this surface. The bundle of ra vs of the first order diffracted from the grating is reflected by the partly silvered surface C' in such a direction that on subsequent refraction at the surface C', the mean angular direction is parallel to the axis of the instrument. A portion of the light from the lens B enters the prism C at the surface C<5> and emerges from the surface C<3> parallel to its original direction, so that an observer at D sees the image of the slit, superimposed upon the spectrum. The prism C may be tilted about an axis parallel to the slit to move the spectrum relatively to the image of the slit by means of a screw acting at right angles to the axis so that the travel of the screw is proportional to the sine of the angular movement of the prism C, a graduated drum on the screw thus being an approximate scale of wavelengths. The image of the slit can be displaced in the direction of its length by making the surface C<5> other than parallel to the axis of rotation.
Patent GB-679761-A (GB)
Title: Improvements in or relating to a method for dissolving normally gaseous agents in thermoplastic resins
IPC: B29C44/34
Filed: 1950-05-15
Abstract: Homogeneous compositions of a thermoplastic resin and a normally gaseous agent which undergo expansion to form cellular products are continuously manufactured by feeding the molten resin through one or more restricted orifices into a mixing zone at an applied pressure so as to form within the inlet to said zone a plastic seal, feeding a resin soluble normally gaseous agent at super-atmospheric pressure into the mixing zone and agitating the mixture of the resin and the gaseous agent; the mixture is then forwarded under pressure through a temperature regulating zone where it is brought to a temperature below the critical temperature and boiling point of the gaseous agent, and the resulting composition is charged to a vessel where it is stored at a pressure sufficient to maintain the composition as a solution of the normally gaseous agent and resin; releasing the pressure converts the thermoplastic resins to the cellular form. Thermoplastic resins specified are polymers and copolymers of styrene, ortho and para chlorostyrenes, dichlorostyrene, meta and para methyl styrenes, alpha methylstyren, ortho and meta ethylstyrenes, para iso-propylstyrene, methyl methacrylate, and vinyl chloride.  Suitable normally gaseous agents are methyl and ethyl chlorides, dichlorodifluoromethane, methyl ether, methyl ethyl ether and gaseous olefines such as propylene and butylene. The process is preferably put into operation by the addition of a small amount of high boiling solvent, such as ortho dichlorobenzene, diethylbenzene, 2-ethylxylene and iso-propylbenzene, to the molten resin in the mixing zone to form a plastic plug flowable at the lower temperatures employed in the heat exchanger; the normally gaseous agent is then fed under pressure to the molten resin.  Specification 406,267, [Group XIII], is referred to.
