Title: Improvements relating to indexing mechanisms for multi-station machines
Inventor: NASH DENNIS REGINALD GEORGE
IPC: B22C11/00
Filed: 1955-07-13
Abstract: 826,632. Indexing; moulding-machines. BIRMIDAL DEVELOPMENTS Ltd. July 13, 1956 [July 13, 1955], No. 20237/55. Classes 83 (1) and 83 (3). Indexing mechanism for multi-station machines, particularly adapted to a foundry coremaking machine, comprises a power-operated oscillating driving element which is connected and disconnected with a rotary driven member by relative axial movement, the rotary driven member thus receiving intermittent part rotation in one direction only. The part to be indexed is secured to shaft 24, which is raised by an air cylinder or other means, and has secured thereto a star wheel 22 with four radial slots 21. A pin 20 on the end of an arm 18 normally engages one of the slots, and on rotation of the arm in one direction, indexes the star wheel through a quarter turn from position 2211 to 22<SP>1</SP> (broken lines). The shaft 24 and star wheel are then lifted to release the pin 21 from the slot and engage the slot with a fixed pin attached to a bracket 26, which thus holds the star wheel in the indexed position. The pin 18 and its arm then return to the initial position in line with the next slot in the star wheel. The latter is subsequently lowered to engage pin 18, and receives a further indexing movement when the arm moves. A double-acting air cylinder 6 is arranged at the side of the arm 18, the latter being secured to a sprocket quadrant 16 engaged by a chain 13 stretched along the side of a beam 12 secured to the piston rods in the air cylinder. The chain thus acts similarly to a rack and is held against the sprocket quadrant by a roller 15. The indexing mechanism may be employed in a core-making machine described in Specification 826,633.

Abstract: 680,221. Microscope objectives. WRAY (OPTICAL WORKS), Ltd. Aug. 10, 1950 [Aug. 10, 1949], No. 20840/49. Class 97 (i). A microscope objective has a concave reflecting surface and a convex reflecting surface of smaller diameter, which obscures part of a central aperture in the concave surface, formed as two of the external surfaces of a transparent block, the radius of curvature of the convex surface being less than one-half of that of the concave surface so that spherical aberration for the required conjugate foci is at least in part corrected. The reflecting surfaces are prefer. ably spherical and substantially concentric and the light entry and exit surfaces of the block may have their centres in the object and image planes respectively. To give full correction of spherical aberration and coma, a convergent lens system, preferably a doublet, may be located on the long conjugate side of the block. In order to increase the working distance and reduce the obstruction of the concave mirror by the convex mirror, the objective has the form shown. This objective comprises a glass block 4 having substantially concentric concave and convex reflecting surfaces R<SP>1</SP>, R<SP>2</SP>, an entry surface R<SP>3</SP> centred in the object plane, and a lens B cemented to the block and having a surface R<SP>4</SP> correcting for coma and spherical aberration, in combination with a doublet C, D. The objective may comprise a block having cemented thereto a member of the same material, this member extending forwardly to the object plane so that immersion fluid may be used. To reduce diffraction effects caused by obstruction of the concave mirror aperture, the objective may incorporate a neutral tint filter whose transmission varies over its area. Optical data are given for two examples.

IPC: H02K33/02
Filed: 1929-07-08
Abstract: 336,224. L'Estrange, W. O. July 8, 1929. Electromagnets; reciprocating machines. - In an electromagnetically operated tool which requires an accurate rectilinear motion, such as used for cutting, depositing, stamping or embossing fabrics, plastic materials &c., a main solenoid has a guided core with a tubular nonmagnetic extension to which the tool is attached, and this extension also serves as a guide for the core of an auxiliary solenoid which may also operate a tool. In the form shown, the cylindrical core A of the main solenoid B slides on fixed guides E and has a nonmagnetic extension C to which the main tool D is attached. This extension, which also serves as a guide for the core K of the auxiliary solenoid J, is guided by a bush H. The solenoid J operates an auxiliary tool M, the auxiliary solenoid core being returned by the spring S. A ring N, fixed to the core extension C, and a spring-controlled pawl P actuated by an electromagnet Q serve to restrain the core A after it has returned a part of its stroke, but when the auxiliary solenoid has been operated, the electromagnet Q releases the core A. The solenoids B and J are operated in sequence by remote control and are energized momentarily. The tool may be turned horizontally by rotating the flange F by mechanical means, the screw X in the hub portion of the flange being first removed. In a modified form not employing an auxiliary solenoid, the flange F carrying the guides E has teeth cut on its periphery so that it can be rotated by a worm.
