Inventor: CHARCHAROS ANTHREAS NICHOLAS
IPC: F22B1/06
Filed: 1964-05-25
Abstract: 1,101,773. Tubular heat exchangers; steam superheaters. BABCOCK & WILCOX Ltd. 24 May, 1965 [25 May, 1964], No. 21554/64. Headings F4A and F4S. A heat exchanger comprises straight parallel tube lengths 3 with their axes lying in a plurality of concentric, circular or circularly arcuate rows together constituting an inner and outer group of rows (in the spaces 4, 5 respectively. Each tube length of one group is a limb of a U-tube of which the other limb is a tube length of the other group. In each group the spacings between adjacent axes in any one row are uniform and any one axis in each row is equidistant from two axes that are adjacent each other in the or either next row, the distance P between an axis in any row and each of the two axes in the or either next row from which said axis is equidistant being equal for all adjacent rows. In a modification, the dimension P need not be applicable tothe innermost row of tubes in the space 4. As shown, the angle B between two adjacent radial rows of the inner group is twice that of the angle B/2 between adjacent radial rows of the outer group; and the U-tubes with one limb forming a radial row in the inner group have their respective other limbs forming two adjacent rows of the outer group. The invention is particularly applicable to a steam superheater such as described in Specification 1,101,772.

Title: Improvements in or connected with percussive deep boring apparatus, also applicable for upward boring
IPC: E21B1/02
Filed: 1923-08-27
Abstract: 225,277. Reichwald, A. W., (Schweitzer, E.). Aug. 27, 1923. Bore-hole apparatus.-In apparatus for upward or downward percussive boring in which the boring bar falls by gravity, the lift is effected by a flexible connection, such as a rope, directly attached to the piston-rod of a single acting motor with self-reversing valve gear. A rope 7 passes from a handle and ratchet-controlled roller 8 over a fixed pulley 9, over a pulley 6 in a stirrup 5 connected to the drill rods 4, to a rock-lever 10 attached by a flexible connection to the pistonrod 11 of a single-acting air or steam engine 12, the valves of which are operated as by tappets; the engine 12 raises the rods 4, which then fall by gravity. The rock lever 10 may be omitted, the rope 7 being then connected directly to the piston-rod 11. In upward boring as shown, the stirrup 5 may be connected by a rope &c. 14 to a piston in a cylinder 17, the piston being constantly acted upon by fluid on one side and assisting the fall of the rods. In downward boring, the rods depend from the stirrup 5 which is carried by a cross head sliding in vertical guides.

[Classes 39 (ii) and 75 (iv)] In an electric torch or battery lamp of the kind wherein the bulb socket is slidable along the optical axis for focusing purposes the sliding movement is communicated to the bulb socket 18 from an external button 23, slidable longitudinally on the lamp casing, by means of lever mechanism which is so arranged that a given displacement of the button produces a smaller displacement of the bulb socket. The bulb socket 18 is slidable vertically within a sleeve 12 and is provided with two outwardly projecting pins 22 which engage within longitudinal guiding- slots in the sleeve and extend therethrough into an arcuate slot 16 in the adjacent arm of a two-armed lever or yoke 13 which is pivoted between lugs 11 on a metal base 10. The free ends of the lever arms are connected by a small crossbar 28 of fibre, which is provided with a central aperture to receive the end of the shank of the operating-button 23. The shank passes through a longitudinal slot in the casing and carries a brass sleeve 25 surrounded by a spring 26 which is held compressed by a cotter pin 27, whereby the button is clamped lightly to the casing. Connection to the centre contact 21 of the bulb is maintained by a flexible wire 20 soldered thereto. The bulb socket 18 also moves within a guide ring 6 carried by an inner metal cap 5 screwed into the top of the lamp casing, the central part of the cap 5 being dished to receive the lower part of the reflector 3 and an insulating sleeve for the guide ring 6. In the example, the invention is applied to a torch provided with an extensible casing and a regulating resistance as described in Specification 453,044.

Abstract: 834,021. Controlling light flux. BAILEY METERS & CONTROLS Ltd. July 17, 1957 [July 17, 1956], No. 22073/56. Class 75(4) Means for producing a light flux which remains constant, or' which varies in a desired manner, with limited variations in the degree of energization of an electric lamp or lamps, comprises a light source including at least one incandescent electric lamp, light attenuating means adapted on movement to attentuate the light flux in a selected direction and an automatic adjusting means responsive to variations in the degree of energization of the lamp which adjusts the position of the movable member of the attenuating means. In the form shown, light from the source 1 reaches a lens 3 by way of two superposed plates 5, 6 having sets of parallel slits 7, 8, the plate 5 being fixed and the plate 6 movable so as to vary the overlap of the slits. The plate 6 is carried by springs and connected at one end to a former 16 carrying a helical coil 23 about half of which lies within an annular space in a permanent magnet 18 of the type having a central pole 18a and an annular pole 20. The coil is connected in parallel with the lamp through a metal rectifier, a smoothing condenser being arranged in parallel with the coil. It is also possible to connect the coil in series with the lamp in some cases. The moving plate can be provided with radially extending slots and be mounted to rotate about an axis at right angles to its surface. Alternatively, the Light attenuating means may consist of a set of parallel louvres which move from a position where they offer little obstruction to the light flux into one in which they completely obstruct the light.

Title: Improvements methods and apparatus for inspecting colour contrasts
IPC: B41F33/00
Filed: 1959-06-26
Abstract: 876,934. Colour inspection by infra-red radiation. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 26, 1959 [June 30, 1958], No. 22087/59. Class 40(3) An apparatus for inspecting the quality of printing, i.e. the degree of inking, on each card of a run of cards comprises means for scanning each card with infra-red light, means for producing signals which are indicative of reflectivity of the area scanned, means for integrating the signals, and means for comparing the output of the integrating means with predetermined minimum and maximum values. A rejection unit may be provided which will be energized if the integrator output falls outside such values. The cards are passed beneath an optical system 10, 12, 16 which focuses an elongated beam of light through a filter 13 on to the cards. A photo-cell 14 receives only reflected light. Its output is amplified and integrated, the integrator 21 being set in accordance with the scanning rate. The integrator output passes to comparators 23 and 24 wherein the output is compared with values indicative of the minimum and the maximum ink quantities allowable on a card. The comparator outputs trigger a circuit 25 to an accept or a reject condition according to the quality of the printing. This circuit is set to the reject condition before the inspection of each card. As the trailing edge of an inspected card passes a second photo-cell a pulse 26 is passed to a coincidence circuit 27 which gives an output which is utilized to accept or reject the card. The pulse 26 also passes via a delay circuit to reset circuit 25 to its reject state, and direct to unit 21 to reset the integrator.
