Abstract: 456,363. Magnetic compasses. LUND, J. H. L'ABEE-, 4, Tennisveien, Oslo, Norway. May 8, 1935, No. 13607. Convention date, May 8, 1934. [Class 97 (ii)] A march-indicating pointer 3 and a N-S pointer 2, e.g. a compass card, are supported on the magnetic needle 1 so that they can be adjusted to any desired angle relative to the needle 1, two independent adjusting devices operated from outside the compass casing being provided for setting the pointers. As shown, the compass casing comprises two relatively rotatable rings 11, 12 made of the material known under the Registered Trade Mark " Bakelite," having co-operating flanges 13, 14 and carrying respectively the glass cover plate 9 and the glass bottom plate 7. The rings 11, 12 are prevented from falling apart by a wire 17 formed with horizontal waves and extending throughout a channel formed by peripheral grooves 15, 16 in the flanges 13, 14. The compass needle 1 is fixed to a flange 33, Fig. 3, on a cylindrical centrepiece 31 having a conical recess 32 in the lower part and carrying at the top the jewel 37 which normally rests on the pivot pin 5 fixed to the centre of the bottom plate 7. The compass card 2 is fixed to a bearing 38 surrounding the cylindrical part 34 of the centrepiece 31 and having at the top a diametrical slot 41. The march-indicating needle 3 is fixed to a bearing 43 encircling the bearing 38 and having at the top a conical surface 46. To effect the adjustment, a lever 29 is rocked by rotating the ring 24 with a camshaped part 30<1>, whereupon a conical surface 10 on the lever 29 engages the conical surface 32 and lifts the needle assembly until the conical surface 46 engages a conical surface 47 on a sleeve 8 fixed in the cover plate 9. The pointer 3 may then be turned relatively to the compass card 2 and needle 1 by rotating the ring 11 relatively to the ring 12. In order to turn the card 2 relatively to the needle 1 for correcting the adjustment for magnetic variation, a screw 19 threaded in the sleeve 8 is rotated until a key 42 enters the slot 41, further rotation then effects the adjustment. The adjustability of the needle 1 relatively to the card 2 is limited by lugs turned down at the ends of a slot in the card 2 or by bending the end of the needle 1 up through the slot.

Title: Improvements relating to methods and machines for forming shell moulds and/or cores
Inventor: MALONE BERNARD
IPC: B22C15/24
Filed: 1968-03-21
Abstract: 1,260,303. Mould-machines; core boxes. FOUNDRY & METALLURGICAL EQUIPMENT CO. Ltd. 21 March, 1969 [21 March, 1968], No. 13762/68. Heading B3F. Half 16B of a core-box or mould-box is closed on to a fixed half 16A to form, around a mandrel 36 (or, as described, each of four mandrels) suspended from a carrier 35, a cavity which is filled with (binder-coated) sand by blowing, e.g., downwardly or from a raisable blowing manifold 15, to form shell cores or shell moulds 38 before the box half 16B is retracted as shown, leaving the shell 38 supported on the mandrel until detached. The retraction of box half 16B causes fluid operation of a cylinder 31 (by action of a valve 33) to move the mandrels 36 and shells 38 out of the fixed half 16A. The mandrels 36 and their carrier 35 are then slid along a horizontal slide-way 34 to a side position over a wire slide 42 before an ejector plate 44 is lowered and sleeves 42 are slid down the mandrels to drop the mouldings 38 on to the slide 42. The box halves 16A, 16B and their supporting plates 20, 21 have heaters and in each mandrel 36 is an electric element 48 so that the mandrel can be heated before sandblowing and/or during curing. After a moulding cycle, loose material is blown from various parts of the machine by automatically-operated nozzles, and then similarly, mist sprays of lubricant and release agent are applied before brushes 52 clean the bottom of the box 16A, 16B and the top of the blowing manifold 15. The machine is automatically controlled to perform a number of moulding cycles or may be stopped by an operator. An air-supplied sand box 11 may be automatically refilled from a hopper 13.

Filed: 1943-08-24
Abstract: 569,673. Photogrammetric apparatus. TROREY, L. G. Aug. 24, 1943, No. 13827. [Class 97 (ii)] In photogrammetric apparatus an image is formed on the drawing surface by a mirror which has a uniform coating over the whole front surface, whereby part of the incident light is reflected and part transmitted so that the strength of the reflected image is a definite ratio of that of the transmitted image. The apparatus comprises a drawing surface on which stands an adjustable transparent copy board adapted to be illuminated by transmitted light and an adjustable mirror and head rest combination. The copy board d is rotatably mounted at c<1> in the forked member c rotatable in the member b which moves by spring- pressed slides in one direction over the base a. The rotation of the copy board about its horizontal and vertical axes is effected by movements of the knurled knob acting through sheathed wires e<11>, e<22>, locking means being provided. The head rest and mirror combination comprises a stand f<1>, f<2> having feet g<1>, g<2> adjustable by screws h. The stand supports the flattened head rest k and links p pivoted to the stand hold the rotatable supports o of the mirror m. The mirror may be locked in adjusted position. In the rectifying process, the photograph having control points marked thereon is mounted on the copy board so that their principal points are coincident. On a transparent grid the relevant control points are marked. The grid is reversed and placed on the drawing board so that its principal point is coincident with the image of the principal point of the illuminated photograph. The orientation of the grid is corrected by rotation about the principal point and the image scale set to give the closest approximation of the control points of the image with the control points marked on the grid. The tilt control knob is manipulated to encompass all possible combinations of vertical and horizontal tilt, locked at the point which shows least deviation and detail traced off in the ordinary way.

Patent GB-646910-A (GB)
Title: Improvements in or relating to the catalytic conversion of hydrocarbons and the like
IPC: C10G11/18
Filed: 1942-10-06
Abstract: In processes for the catalytic conversion of vapours, e.g hydrocarbons, of the kind in which the finely-divided solid contact or catalytic agents are flowed cyclically through reaction and regeneration zones, the flow of vapours and regeneration gases through the reaction and regeneration zones respectively is controlled to maintain in these zones a lower "dense" phase and an upper "dilute" phase of the reactants and a highly turbulent motion of said dense phase, and used contact agent is withdrawn from the conversion zone separately from the vaporous conversion products through a withdrawal passage opening directly into and <PICT:0646910/III/1> terminating below the upper level of the "dense" phase.  The process is described with reference to a reactor 6 and a regenerator 21 in which dense phase zones A, A1 and "dilute" phase zones B, B1 are maintained.  The oil feed introduced through line 4 is mixed with regenerated catalyst from standpipe 2 and, if desired, with steam fed in at 44 and passed through feed line 3 into the base 5 of the reactor 6.  The majority of the catalyst disengages from the cracked vapours in zone B, provision for separation of residual catalyst being made by way of cyclone hoppers 13, 14 through which the vapours pass off via line 17 to the usual fractionating and refining apparatus. The contaminated catalyst is removed through a side passage 9 in the lower part of zone 6 and after stripping with gases supplied through line 10 is passed down stand-pipe 11 at the bottom of which it is mixed with air as regenerating gas and the mixture fed through line 19 into the base of the regenerator 21. This latter is also provided with a side passage 24 for draw-off of regenerated catalyst to stand-pipe 2 and a second side passage 23 by which regenerated catalyst is recycled to the regenerator through stand-pipe 43, feed-pipe 55 and cooler 22, so that the temperature of regeneration may be controlled.  Waste regeneration gases containing residual catalyst in suspension pass through waste gas cooler 27, precipitators 31a, 31b, 31c and a Cottrell precipitator 32, the recovered catalyst being accumulated in hopper 36 and recycled through line 40 to the regenerator 21.  In a modified form of apparatus (Fig. 4, not shown) the catalyst is withdrawn from the zones at points below the points of entry of the vapours and regenerating gases respectively while the catalytic material is introduced into the upper portions of the dense phase zones.  The Specification gives detailed tables of the dimensions of the zones and operating data in respect to vapour and catalyst feed rates, catalyst/feed ratios, pressures and temperatures.  Specifications 582,414, 590,456 and 636,524 are referred to.
