Title: Method and machine for imparting compactness and coherence to a granular mass contained in a mould, and improved building block made therewith
IPC: B28B3/02
Filed: 1929-03-04
Abstract: 329,063. Lejmark, R. March 4, 1929. Shaking and jigging machines; stationarymould machines. - In a machine for moulding building- blocks from granular material the mould box 1 is alternately lifted and allowed to fall upon a solid bedplate 10 until the mass settles, whereupon the mould is moved upwardly against a press-plate 21 corresponding to the opening of the mould in order to compress and smoothen the loose portion of the mass in the upper part of the mould. The mould 1 has on its under side a socket in which fits a vertical rod 5 running in guides 4 and actuated by a treadle 3, the rod being normally held in its lowest position by a sliding bar 6. Carried above the mould on uprights is a swinging arm 20 with the press-plates 21 corresponding to the openings in the mould. In operation, the arm 20 is swung out from over the mould so that it can be filled with aggregate, the sliding bar 6 is retracted and the mould raised by depressing the treadle 3, which is then released so that the mould drops upon the bed-plate 10. This is repeated once or twice and the arm 20 is then swung over the mould and locked to the uprights, the treadle 3 is depressed and the mould struck against the press-plates 21 to compress the top layer of aggregate. The arm 20 is then swung back, the rod 5 locked by the sliding bar 6 and a lever 7 lowered to raise a number of rods 15 through a shaft 19, levers 18, links 17 and rods 16. The rods 15 pass through the bedplate 10 and bottom 9 of the mould and raise the loose bottom 11, Fig. 3, with the finished block, which is turned over on a pallet and placed aside to harden. Distance pieces 13 are placed between the bottom of the mould and the loose bottom 11 to determine the height of the block, and openings in the sides of the mould allow of the escape of particles which have fallen through the loose bottom. Vertical cores 12 fixed to the bottom of the mould give the block a number of vertical holes which may pass wholly or partly through it. The sliding bar 6 is operated by moving the lever 7 laterally, the lever co-operating with lugs 8 on the bar. In the machine shown, two moulds are combined. The cores 12 are arranged so that the number of cells formed in the block is one-tenth the area of the face of the block in square centimetres.

IPC: G01G13/00
Filed: 1939-03-04
Abstract: 525,992. Automatic-feed weighers; delivering material from hoppers. TRIGGS, W. W. (Bates International Bag Co.). March 4, 1939, No. 7198. [Class 143] [Also in Group XXX] A bag filling apparatus comprises a weighing device on which two spouts are mounted, each spout being adapted to enter the valve of a bag, means for supplying a stream of material, two paths or channels one for communication with each spout, and means for deflecting or switching the stream alternately to the two paths or channels for alternately delivering the material through the spouts. The material in a supply hopper 190, Fig. 13, is drawn by a constantlydriven belt 186 past a feed gate 185 and is directed by a guide 192 to a pivoted deflector which diverts the material into one or other of two circumferential grooves in a rotating feed wheel 25, Fig. 1. An endless belt 27 closes the lower portions of the grooves so that the material is fed through one or other of two-bagsupporting spouts 28 mounted side by side on a bag support suspended from the scale beam 31. The bags, when on the spouts rest on tiltable bottom supports 34. With the mechanism in the position shown in Fig. 1, the major portion of the charge has entered the first bag 42, a locking stop 179 actuated through a link 176 by cam mechanism has been removed from beneath a stop 180 on the scale beam, and the feed gate 185, Fig. 13, has been simultaneously lowered to a reduced-feed position. The charge is completed by the reduced feed and the scale beam raises a rod 128. The rod, by displacing a catch causes the pivoted deflector to swing over and direct the feed to the second spout, and at the same time a half-revolution clutch on the cam shaft is coupled up. Cam mechanism operating through rods 219 and 158 then releases a clamp 321 from the top of the bag, and raises a roller 162 to tilt the bottom support 34 and discharge the bag. The scale beam then rocks in the reverse direction, the locking stop 179 again locks the beam, and the feed gate 185 is raised by the cam mechanism to allow a full feed to the second bag on the second spout. A cam operating through a rod 199 raises a housing 200 containing a rotating eccentric 205 connected by a rod 206 to a jigging plate 211 which jigs the bottom support of the second bag whilst the major portion of the charge is entering. The cam mechanism again removes the locking stop from the scale beam and the reduced feed is brought into operation to complete the charge, the operations in connection with the two spouts proceeding alternately in the manner described.

In a variable capacitor the stator unit includes a ceramic dielectric element to which there is applied or secured a conductive area forming a stator plate, and a switch is provided which is actuated, e.g. to switch in a further capacitance, when the rotor is at a predetermined position with respect to the stator. In Fig. 1 the stator includes a dielectric element 3 comprising two arcuate metallic areas (shown dotted in the drawing) sandwiched between two ceramic discs. The rotor comprises an insulating member 6 carrying on one face (not shown) a sector-shaped stainless steel plate or metallized surface. The member 6 has two slots 10 engaged by lugs 11 provided on a plate 12 fixedly secured to the end of the spindle 8. The lugs 11 make electrical contact with the rotor electrode, and the angular position of the rotor relative to the spindle can be adjusted by moving the lugs in the slots 10, the slots 10 then being filled with wax or other filling. The plate 12 is adapted, e.g. in the maximum capacitance position, to engage switch contacts 13, the spatulate end 13B on one contact being contacted by the end 13C of the other; the contacts may bring in a further capacitance to change the tuning range of the capacitor. The dielectric element 3 may be formed from a sandwich consisting of a first ceramic layer 0.03 inch thick, the electrode forming material (preferably a metallized layer), and a further ceramic layer 0À01 inch thick, both ceramic layers being in the unfired or green state. After the sandwich has been fired the second ceramic layer, which forms the dielectric of the capacitor, is ground down to a thickness of 0À002 inch. A third screening arcuate strip may be provided between the two electrode arcuate strips and may be electrically connected to the spindle via a commutator-like sliding contact (drawing accompanying the Complete Specification, not shown). The dielectric element 3 may be secured to raised segments 23, of which only a few are shown, on a resilient mounting 4 which is backed by a backing disc 5 which may be, but preferably is not, secured to the mounting 4. The stator unit, comprising units 3, 4 and 5, is urged towards the rotor by a spring 25. The mounting 4 is provided with lugs 24 to locate the assembly in a housing 13A, and the spindle 8 may be provided with a lug 8D engaging a track 13D in the housing to limit the rotor movement, e.g. to 180 degrees or 190 degrees.

Title: Improved process for treating and dyeing photographic images and products obtained thereby
IPC: G03C5/48
Filed: 1921-03-11
Abstract: 160,137. Kelley, W. van D. March 11, 1921. Toning; colour photography.-In a process for obtaining colour transparencies by bleaching the silver image and subsequently dyeing it, the silver image is bleached in a bath that will transform the silver into a compound which is insensitive and not redevelopable by a developer, and then dyed in an acid or azo dye bath, which is mordanted only at the places in situ with the original silver. The image film may be first hardened by a formalin bath. The bleaching bath contains a copper or chromium salt or both. A bath instanced contains potassium bichromate, potassium bromide, copper sulphate, and hydrochloric or acetic acid. The image may then be treated in an acid fixing bath of hypo and sodium metabisulphite, or this may be done after dyeing. Acid or azo dyestuffs instanced include ponceaus, fast reds, acid fuschine and dyes such as used in wool dyeing, which give a choice of pure non- dichroic colours and a very transparent image. To brighten the colour a bath of ¢ per cent solution of sulphurous acid may be used. The process is used to obtain one or more of the component colour elements in a two or three colour photograph or kinematograph film, either in the same emulsion layer or on separate films.
