Title: Improvements in radiation apparatus including means for oscillating a beam of radiation in a plane
IPC: G01J3/06
Filed: 1953-09-04
Abstract: 730,362. Spectrometers. PERKIN-ELMER CORPORATION. Sept. 4, 1953 [Oct. 8, 1952], No. 24567/53. Class 97 (1). [Also in Group XL (b)] A beam of radiation is reflected from a plane mirror mounted for continuous rotation about an axis inclined at a small angle to the normal to its surface and is returned to it, for a second reflection, either by a roof reflector or by a second, similarly mounted, rotating reflector, whereby after the said second reflection, the beam is swept back and forth in a single plane. In the spectrometer shown in plan, radiation from a source S is concentrated through a sample 21 on to a slit 11, collimated by a lens 12 and dispersed by a prism 13. After reflections by members 14, 17 it is further dispersed and reflected by a mirror 19, the selected wavelength emerging from the slit 18 on to the detector 20. A normal to the mirror 14 is inclined at a small angle to the spindle 15 of a motor 16 which rotates it. The member 17 is a roof formed of two mirrors intersecting horizontally. This cancels any vertical component of displacement produced by the mirror 14. It may be replaced by a mirror, similar to 14, but having double the inclination and being correctly phased with the mirror 14. The mirror 14 may be partly masked to different extents at different parts of its circumference to equalize the sensitivity of the instrument at different points of its wavelength range.

Abstract: 1,103,024. Brake adjusting devices. AUTOMOBILES M. BERLIET. 10 June, 1965 [16 July, 1964], No. 24594/65. Heading F2E. An automatic wear compensator mounted in a brake-actuating cylinder 1 comprises a rod 10 on which is clamped at least one split-ring 12 which is moved by an abutment 15 on the cylinder piston 4 to take-up brake wear, but which prevents the brakes returning by more than a predetermined amount E when the brakes are released. As shown, four rings 12 are clamped on the shaft and are moved by the abutment 15, which is a circlip fitted to a groove in the piston, through an intermediate washer 14. The frictional grip of the rings is such that whilst the resilient means returning the brake shoes cannot move them on the rod 10 an additional force applied to the piston end 8 enables them to be returned to the centre of the rod when new brake linings are fitted. A groove 9 in the outer end of the rod prevents the rings being forced off the end of the rod.

Abstract: 1,166,472. Injection moulding machines. INVENTIONS FINANCE CORP. 3 Sept., 1966, No. 24819/66. Addition to 1,075,801. Heading B5A. In an injection moulding apparatus an injection piston 18 extends into an injection chamber 14 and contains a transfer chamber 23 to which moulding material is continuously fed, the material being transferred therefrom by a piston 20 into the injection chamber 14 through a non-return valve 24. The injection piston 18 comprises a sleeve and is moved to the injection-completed position seen in Fig. 2 (not shown) by pistons 41 acting on lateral extensions 38, 39 thereof. After injection and during cooling, a feed screw 22 continues to feed material to the transfer chamber 23 until a pressure build-up forces the piston 20 therefrom (Fig. 3, not shown), the non-return valve closure member 31 remaining seated on the end of the sleeve 18. Fluid is then admitted to cylinders 46, thereby withdrawing rods 48 and the sleeve 18 attached thereto (Fig. 4, not shown). Simultaneously fluid is exhausted from the cylinders 40, the screw 22 continues to rotate and material is transferred through passages 32 in a head part 29 of the valve into the injection chamber. When the sleeve 18 has withdrawn fully (Fig. 1) injection is initiated by evacuating fluid from the cylinders 46 and supplying fluid to the cylinders 40. During injection the sleeve 18 affords a seating for the complementarily shaped end of the valve member 31. The injection orifice may be provided with a regulator valve 100 (Fig. 8) comprising a cylindrical housing 101, a nozzle 102 and a needle valve closure 103, a central bore 104 thereof opening into the injection chamber 14, a point 106 of the needle valve closing the nozzle 102. An hydraulically operated lever 108 pivoted at 109 acts on a shoulder 107 of the needle to regulate the passage of material through the nozzle 102. The lever is acted on by a piston 110 in a regulator cylinder 111 supplied with pressure fluid through a conduit 112.

IPC: F22B1/18
Filed: 1965-06-15
Abstract: 1,147,064. Tubular heat exchangers; steam generating boilers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 15 June, 1966 [15 June, 1965], No. 25317/65. Headings F4A and F4S. [Also in Division G6] Each of a plurality of heat exchangers, (1, Fig. 1, not shown), disposed within the annular primary coolant passage formed around a central reactor core 4, comprises three tube stacks 6, 7 and 8 of square cross-section, arranged side by side and each comprising a plurality of flat tube arrays, the ends of the tubes from each array being made to pass through a circular hole 12 of diameter slightly greater than the diagonal of one such stack and formed in the top wall of the reactor. Each tube array is in itself a boiler, for example, a steam generating unit comprising economizer, evaporator, superheater and reheater sections and comprising preferably separate channels which can be blanked off individually or in groups. The arrays are arranged so that in any one exchanger the tubes of the outermost two arrays 6 and 8 are perpendicularly disposed to those of the middle array 7, and are of such shape that they can be inserted through, and disposed to either side of, the hole 12, the intervening space then being filled by the tubes of the middle array. Thus, for example, to withdraw the tubes, the central array, whose ends are shown by cross-hatching, is removed by firstly lifting tube sections 14, located within a central passage 13, and then moving the remaining tube sections (cross-hatched) into the central passageway and similarly lifting out. This leaves passageways 15 between adjustment tube sections of the extreme arrays. The tubes 6b of one of these remaining arrays are then moved towards one of the passageways 15, formed in the other remaining array, and lifted out, after which sections 6a, 6c &c. are subsequently moved to the position formerly occupied by tubes 6b and the procedure repeated. The individual arrays may be connected in parallel to headers outside the reactor.

Abstract: 927,906. Magnetic storage devices. FORD MOTOR CO. July 24, 1959, No. 25451/59 Class 38 (2). [Also in Group XXXIX] A logical gate circuit comprises a block 10 (Fig. 1), of ferrite or other magnetic material provided with parallel read and bias conductors 13, 14 and with sense and input conductors 15-18 arranged perpendicular thereto, saturation or near saturation being produced in the magnetic material around the hole 11 by a bias current in 14 so that provided that no current flows in any of the proposition conductors 15- 17, a sense pulse current in 18 larger than the bias current causes saturation in the magnetic material around the hole 12 resulting in collapse of the orthogonal bias flux where the two fluxes cross and thus producing an output in the read conductor. If, however, the sense pulse is preceded by a current in any of the input conductors, this latter causes collapse of the bias flux so that a subsequent sense pulse produces no output. The " or " condition is indicated by a nil output on the application of a sense pulse. When none of the inputs have been energized an output is produced by a sense pulse, the device being said to act as an " and " gate. The read conductors of a number of " and " gates may be connected in series, or parallel or series parallel to form an " or " gate so that a pulse is produced when the " or " condition is satisfied. The proposition and sense conductors may be arranged in different holes 20 (Fig. 2), which need not be parallel (and may be perpendicular) provided that they are in directions perpendicular to the holes carrying the read and bias conductors which they need not intersect. The conductors may be held in position and surrounded by uncured ferrite which is subsequently fired to form the core. Specification 927,905 is referred to.
