Title: Process for the manufacture of ammonium sulphate
IPC: C01C1/247
Filed: 1929-10-25
Abstract: The production of ammonium sulphates by the oxidation with air &c. of initial materials comprising ammonia and sulphur dioxide in the presence or absence of water or water vapour is effected in the presence of nitrogen oxides (excluding nitrous oxide) or of substances, for instance salts of nitrohydroxylaminic acid, which yield nitrogen oxides under the reaction conditions.  Initial materials specified are solid ammonium sulphite or bisulphite, aqueous solutions thereof, and gaseous ammonia and sulphur dioxide. Oxidation of the gas mixture is effected in the presence of water or water vapour; for instance by conducting it together with oxidizing gases and nitrogen oxides into water.  Elevated temperatures, e.g. 80 DEG C., and increased or reduced pressure may be used for the oxidation.  When treating solids oxidation may be effected in two or more stages, whilst liquids to be treated may be either acid or basic.  Solid ammonium sulphate may be obtained directly from gaseous mixtures.

Patent GB-886689-A (GB)
Title: Method of loosening and conditioning a stack of sheets
IPC: B65H3/60
Filed: 1958-10-13
Abstract: 886,689. Conditioning paper; cockling paper &c. FRUTH, H. F. Oct. 13, 1958, No. 32639/58. Class 96. [Also in Group XVI] Apparatus for loosening sheets in a stack which is placed in a chamber which is sealed and then evacuated (see Group XVI), can also be used for moistening, drying, perfuming, or otherwise conditioning the sheets, and can be used for producing " cockled " sheets such as are used as copy sheets in typewriters. As shown, a vacuum tank 10 for a stack 12 of paper or the like having an open top 14 sealed by a lid 15, is connectible : (a) to atmosphere through a valve 28; (b) to a vacuum pump 24 through a vacuum reservoir 23, a valve 22, and pipe 21; and (c) to a gas humidifier 29 through a valve 31 and pipe 30. The air space above the stack 12 may be decreased by light solid or hollow blocks 19, and the sides of the stack are registered by adjustably mounted vertical bars 27. Initially, the pressure in the tank 10 may be at, or above, atmospheric. The valve 22 is opened, and the pressure in the tank falls by about one-eighth of atmospheric pressure within from one to ten seconds, depending upon the weight of the sheets, so that entrapped air between adjacent sheets expands rapidly and loosens the sheets in the stack. This operation may be repeated several times, the pressure being raised between each operation by opening the valve 28 to atmosphere, or to a gas compressor. Alternatively, the pressure in the tank 10 may be raised between each operation by introducing steam, or a water aerosol loaded with finely divided dust from the humidifier 29, so that the sheets are moistened. Where the stack 12 contains freshly printed sheets, the ink is dried by the admission of warm air, and other oxidizing or catalytic agents in the form of gases, dusts or aerosols maybe introduced. Sheets of tissue weight having dome-like buckles or dimples, known as " cockle" sheets, can be produced by increasing the moisture content by from 8 to 12% during the above loosening operation, then, after a sudden vacuum has been produced, dry or heated air is introduced into the tank 10. This operation is repeated until the sheets are dry, whereby each sheet is in " cockled " form. In modifications, the tank 10 may be connected directly to a vacuum pump, and the stack 12 may be introduced through a side door. Further, the tank may be much larger than the sheet stack, and provided with upright registration bars which are urged towards the sides of the stack by a system of pulleys and weighted cords.

Title: Apparatus for the production of pictures appearing to stand freely in space
IPC: G09F19/16
Filed: 1929-10-28
Abstract: 337,956. Stier, F. Oct. 28, 1929. Reflectors.-An image of an object is seen in space by reflection by a rapidly rotating mirror which does not fill the area of revolution, thus appearing transparent and allowing objects at the rear to be seen directly. The mirror 1 may be flat, convex, or concave, and of any desired outline. When shaped as shown in Fig. 5 the brightness of the reflected image is uniform over all its surface, and when shaped as in Fig. 6 the uniform brightness over the central area gradually fades towards the circumference. A mirror having sections 1, Fig. 9, of different curvature from other sections 1<1> will give two images of an object. A lens may be inserted between the illuminated object and the mirror, and the objects behind the mirror may be illuminated from a source of light in front thereof. Alternatively an obturator having an opening similarly shaped to the mirror may rotate synchronously therewith and prevent a light from the front of the mirror reaching objects behind. A plurality of obturators may be employed with a compound mirror such as that shown in Fig. 9. The object reflected may be movable, or interchangeable, or may be a kinema film.

Title: Door closers
Inventor: HERRIOTT LESLIE VICTOR
IPC: E05F3/08
Filed: 1954-11-12
Abstract: 776,011. Door and gate operating-appliances. YALE & TOWNE MANUFACTURING CO. Oct. 11, 1955 [Nov. 12, 1954], No. 32793/54. Class 65 (1). In a door closer the cylinder of a dash-pot for controlling the spring return of an arm 13 pivoted to a housing 11 is formed in or on the arm 13, the piston 24 of the dashpot being connected to a cranked end 12a of a spindle 12 fixed relative to the housing 11. The housing 11 is secured to a door and the arm 13 through a detachable ball-joint 30 and an adjustable link 22 to a fixed member, or vice versa. Rotation of the arm 13 by opening the door tensions a spring 23. At the same time the piston moves to the left in the cylinder 50, liquid (e.g. oil) flowing through a non-return valve 27 in the piston 24 from left to right. As the spring 23 commences to close the door liquid can only pass from the right to the left of the piston through passages 13e, 13g, 13e<SP>1</SP> and a groove 24c in the piston. When the piston moves further to the right the passage 13e is cut off and liquid escapes only through a groove 24b in the piston and passages 13d, 13f, 13d<SP>1</SP>. Needle valves 29, 28 in the passages 13g, 13f are adjustable to control the initial and final rates of closing separately. The passages 13e<SP>1</SP> and 13d<SP>1</SP> may both be covered by the skirt of the piston when the door is open, there then being a time delay while liquid seeps past the piston 24 till the groove 24c communicates with the passage 13e<SP>1</SP> when the door will commence to close. A spring loaded roller 37 may co-operate with a notch 17c in a plate 17 to hold the door in the open position, an initial manual closing movement being necessary. A bushing 14 is secured to the arm 13 to rotate about the spindle 12, a collar 12b locating the axial position of the bushing. A sleeve 19 is adjustably secured to the bushing 14 through a screw 18 and a plate 17, and drivingly engages flats 20a on a rotatable sleeve 20 which carries a pair of dogs 20c. Rotation of the arm in one direction causes each dog 20c to engage an abutment 22b on a spring driving member 22, so rotating the upper end of the spring 23 connected thereto, the other end of the spring being held stationary by a projection 21c on a spring driving member 21 engaging one side of a fixed abutment 10c. Similarly operation of the arm in the opposite direction causes the member 21 to rotate the lower end of the spring, the upper end being held against rotation.

The apparatus is mounted on a trailer 10 having rear wheels 12, 14 and a hitch assembly 20 for attachment to a towing device. The projecting means 38 consists of a centrifugal throwing wheel driven by a motor 40 and supplied with particulate material, such as steel shot or grit, from a hopper 42 and hose 44 for treatment of the surface, such as a roadway. The spent particulate is removed from the surface by the magnetic means 50 comprising a series of stationary magnets 56 disposed within a rotatable drum of non- magnetic material such as stainless steel. The material picked up falls or is removed by a scraper 58 from the drum into a trough 60 having a screw conveyer 62 which transports the material to a bucket-type elevator 64. Any particulate material or debris remaining on the surface being treated is sucked through an orifice 52 into an expansion chamber 64, coarse material dropping into a trough 66 having a screw conveyer 68 and air and fine material passing through an opening 70 into a second expansion chamber 72 having an inertial-type separator 74 provided with a dribble valve 76 for release of any recovered particulate. A suction fan 80 produces the vacuum force at the orifice 52 and exhausts the air to a dust collector 36. The air blast is directed through at least one opening 54 of a box 88 supplied with air by a fan 86 connected to the dust collector 36. The pressure of air in the box 88 is adjustable by means of a bleeder valve 90. The conveyers 62, 68 convey the particulate and debris to the bucket elevator 64 which is connected to a rotating trash screen 106 through which particulate and small debris pass to an air wash separator 100, larger debris being fed to a conduit 110 and trash receptacle (112, Fig. 1, not shown). The particulate material falls from the trash screen into the hopper 42, and an air curtain displaces the lighter material into a receptacle 114 having a dribble valve 116. The air from the curtain passes to a cyclone 120. The material collected by the separator is collected in a container 130 which can be emptied while the apparatus is operating by swinging of a boom (134) to a discharge position.
