Filed: 1939-04-06
Abstract: 527,347. Moulding glazed tiles &c. SCHACHERL, L. April 6, 1939, No. 10825. Convention date, Sept. 30, 1938. [Class 87 (ii)] Articles having a highly glazed surface are made by centrifuging a paste of cement or concrete on to a smooth surface, for example of glass or chromium-plated metal, and allowing it to remain on the surface until it has set. The smooth surface may be formed on a support detachably mounted in a mechanical press and adapted to be removed to allow the cement article formed thereon to set. The support may be profiled and be provided with raised or recessed drawings. In some cases, a second layer of concrete is applied to the first layer and may carry metal letters, mosaic stones &c. which become bound in both layers. The second layer may have reinforcements and connecting elements. In some cases, preshaped concrete plates have glazed layers moulded thereon. Artificial marble may be produced by the addition of colouring matters to the cement. The articles, which may be highly glazed on both sides, include plates, table tops, tiles, wall coverings, window frames, columns, nameplates, tombstones, road signs &c.

Abstract: 1,105,356. Handling foundry ladles. " EDARCO " EUROPEAN DEVELOPMENT & RESEARCH CO. Ltd. 12 March, 1966, No. 10977/66. Heading F4B. [Also in Division B3] Apparatus for scooping molten metal from a crucible and pouring it into a mould comprises a frame 1 having a support 2 and a cover 7. A laterally extending cranked arm 3 is pivotally attached at 4 to the support 2 and carries at its outer end a ladle 9. The arm 3 may be raised and lowered vertically by fluid means 13 such movement also effecting pivoting of the arm by the action of a roller 5 on the inner end of the arm co-operating with the undersurface of the cover 7. Lowering of the arm 3 by means 13 permits, under the control of the roller 5 and spring 25 in the arm guide 23, the immersion of the ladle in the molten metal. The volume of metal scooped into the ladle depends upon the angle of inclination of the arm and this is controlled by an adjustable stop 24 at the upper end of the guide 23. When the ladle is filled, the operation of fluid means 13 raises the arm vertically and pivots the arm into a horizontal position. Fluid means 14 is then actuated to turn the arm and ladle about the vertical axis of the support 2 so as to bring the ladle into position over a mould. Fluid means 15 which is attached to the arm 3 and the support 2 is then actuated to turn the arm about a horizontal axis and so pour the molten metal from ladle into the mould. The whole sequence of operations may be effected automatically.

Patent GB-694112-A (GB)
Title: Improvements in or relating to overload indicating devices
IPC: G05G15/08
Filed: 1950-05-05
Abstract: 694,112. Dynamometers. KING, F. W. May 7, 1951 [May 5, 1950], No. 11173/50. Class 106 (ii). In a device for indicating a mechanical overload comprising a piston 6 movable in a cylinder, a stressable member (e.g. a compression spring 9) to control the position of the piston relative to the cylinder, and an electric contact-set 30, 32 operable by the piston, an overload applied to the piston operates the contact-set only if applied for a time sufficient to allow a predetermined volume of a fluid in the cylinder to pass through a strictive passage. The contacts may close a circuit to give an audible or visible warning signal or to stop the machine to which the device is attached. As shown in Fig. 2, the oil-filled cylinder is formed by a base 1 on which is screwed a cap 2, and a force is applied between base flange 28 and a link 25 screwed on a shaft 12 bearing nuts which engage a plate 18 on the top end of the piston. Contacts 30 are formed by two bolts 60 located in insulating portions of a pivoted ring 61 and connected to wires (not shown) passed through a gland in the base 1. Ring contact 32 is secured to an insulating ring assembly 34, 35 located in an annular piston recess 33 and connected by rods 38 to a further ring assembly, including a fibre or leather ring 47, in piston recess 40. The top ring 49 may be slightly angularly adjusted relative to the others, due to elongated rod holes 44, Fig. 1, thus enlarging or reducing the junction of oil holes 45. Cover-plates 17, 18 are similarly adjustable to affect the junction of oil holes 84, 56. The plate 17 also contains larger oil holes 53 which are covered by plates 59 contained in a diametrical recess 57 of plate 18 communicating with cylinder space 70 through oil holes 58. A normally closed oil-filling hole 72 is provided. In operation, while a steady overload will cause contacts 30, 32 to close, a sudden load will cause the contact 32 to be retracted into recess 33 against spring 41 until the oil pressures in spaces 71, 70 are equalized by flow through circumferential recesses in rings 35, piston-holes 46, holes 45 and 53, and around lifted plates 59. The oil also damps the return of the piston when the load is released, the plates 59 then being forced against plate 17 so that the flow is through holes 56, 84. The device may be applied to a hydraulic crane, Fig. 6, the flange 28 being secured to the boom 80 and the link 25 pivoted in a groove in a beam 82 pivotally mounted in an arm 83 and having the load L applied to its mid-point. Since the effective load applied to the link is proportional to L cos # the device is automatically compensated for the fact that the crane can accept a larger load for a larger angle # between the boom and the horizontal. Two devices may be so coupled or arranged that one gives an overload indication for a load slightly below that which operates the other.

Title: Improvements in or relating to annealing and heat treating furnaces
IPC: C21D1/84
Filed: 1928-04-16
Abstract: 320,841. Kathner, A. T. April 16, 1928. Metal-heating furnaces.-In a continuously. operated furnace for the annealing or other heat treatment of metals having heating or cooling chambers in line, the cooling conditions can be controlled either by varying the volume of gases passing from the heating-chamber to the cooling-chamber, or by opening up various parts of the cooling-chamber to the atmosphere. In the apparatus shown the inner end of the heating chamber a is closed by a transverse wall 9, and a door or damper 11, which can be adjusted vertically to allow more or less of the heating-gases from the chamber a to pass to the cooling-chamber b. The heating-gases which do not pass to the cooling-chamber escape through a damper-controlled stack 8. Loss of heat through the floor of the annealing-chamber may be prevented by a layer 23 of heat-insulating material. The cooling-chamber is longer than the heating-chamber, the lengths being in the ratio of 4 to 3. The roof of the furnace is formed of a number of abutting sections 2, which are of greater height and more thickly lined with refractory material in the heating than in the cooling-zone. The roof sections of the cooler portions of the cooling-zone may be formed of metal lined with asbestos. A tight joint between the side walls and the roof sections is made by sand, and the cooling-zone sections have lugs by which they can be raised more or less when it is desired to allow heat to dissipate rapidly. Specification 320,865 is referred to.

Title: Improvements in and relating to illuminating and viewing apparatus for objects such as photographic transparencies and prints
IPC: G02B27/02
Filed: 1944-06-13
Abstract: 581,088. Apparatus for viewing transparencies and prints. PHILIPS LAMPS, Ltd., and WEST, S. W. June 13, 1944, No. 11318. [Classes 97 (i) and 98 (ii)] Relates to apparatus of the kind described in Specification 387,767. wherein a housing is provided with a diffusing screen against which the transparency &c. is placed, and encloses (1) a lamp which is mounted near one edge of the screen and serves with the aid of a curved reflector to illuminate the screen uniformly, and (2) a movable lamp-masking shutter, e.g. of semi-cylindrical form coaxial with the lamp, for varying the ,intensity of illumination of the screen. The invention consists in providing in the wall of the housing an aperture close to the lamp, and so situated in relation to the masking shutter that the aperture is directly illuminated when the screen is fully masked, and is obscured when the screen is fully illuminated. The aperture affords strong illumination for inspecting dense local portions of the transparency, e.g. an X-ray film. It may be provided with a hinged cover with a reflecting inner surface, so that when the cover is partially open, light from the aperture is reflected to the front surface of the screen and renders possible the viewing of an opaque print laid against the screen. In the form shown, the housing 1 has a curved, internally-reflecting rear wall whereby light from one or more lamps 3, e.g. of the elongated electric discharge type, in a ventilated ,casing 9 is caused to illuminate uniformly a diffusing screen 2 on the front of the housing. Half encircling the lamp is a shutter 5 rotatable by a knob 6 into various positions so that the screen 2 may be illuminated to any degree from obscurity to full intensity. The inner surface of the shutter may be reflective. Near the lamp the housing has a glazed aperture 21 which is illuminated when the shutter 5 obscures the screen 2, and is obscured when the shutter permits full illumination of the screen. An apertured cowl 22 forms an air vent which prevents undue heating of a transparency laid against the window 21. A hinged cover, with reflective inner surface, when partially open permits viewing of an opaque print placed against the screen 2 ; it may be actuated either independently or from the shutter 5. Clips 26 serve to support the transparency or print against the screen. For roll films, spool holders may be provided. Adjustable opaque roller blinds 11, 14 prevent glare from the parts of the screen 2 not covered by the transparency. Ballast resistances and other lamp-controlling gear are enclosed in a casing mounted below the housing 1 and provided with a lamp switch 8.
