Title: Gathering and conveying mechanism for coal and like mining machines
IPC: E21C25/68
Filed: 1947-10-16
Abstract: 632,451. Conveyers etc.; feeding devices YARMAK, J. Oct. 16, 1947, No. 27686. [Class 78 (i)] In coal and like mining machines gathering, sweeping away cuttings, conveying and similar operations are carried out by means of one or several rotary bladed impellers each comprising a plurality of parallel horizontal or slightly inclined plain laminae which are adapted to pass while describing their circular path through a separation wall built up in a similar manner by a number of fixed laminae. The enmeshed profiles of the laminae are formed to contain always a large angle between tangents greater than the selfwedge angle and preferably about 90 degrees. A loader comprises a slightly inclined plate 71, Fig. 5, having two laminated impellers 73, 74 mounted on it. Each impeller comprises several, preferably six, laminae 75 secured to shafts 76 to form two gathering arms 78 and 79. Between each two laminae 75 are attached fixed laminae 80 surrounding bosses 81 of laminae 75 and connected firmly together by their tail ends 82 to plate 71. Shafts 76 are driven by a train of spur and bevel gears from drive shaft 98 of the loading conveyer comprising side chains 101, 102 connected by flights 103 in such a way that the arms rotating oppositely and inwardly gather material and feed it to the conveyer moving in the direction of the arrow in the usual way in the centre of a trough 107. One of the impellers similar to that described can be mounted on the driving head of a cutting machine such as a cuttings-sweeper. Fig. 3 shows an application to a longwall coal face loader and comprises four impellers each having five laminae 46 which are rotated simultaneously in the same direction about shafts mounted in plates 41, the separation wall comprising a number of sheets 56 surrounding the shafts and connected firmly together at their ends. The semi-loose material broken from the wall is collected onto a conveyer indicated on the left. Fig. 7 shows a conveyer for granular material delivering from a hopper 112 comprising two pairs of impellers constructed in the same manner as shown in Fig. 3 providing a closed conveying space 111. The blades are rotated in the direction shown by the arrows. The laminated separation walls 122, 123, however, are in this case mounted so that they can be moved towards each other as far as the dotted line to vary the capacity between a maximum and zero by turning a threaded spindle 130 having left-hand and right-hand threads 131, 132 journalled in nuts secured to the walls.

Title: Process and material for taking dental and other impressions
IPC: A61K6/90
Filed: 1950-11-16
Abstract: Impressions of objects for dental or other purposes are taken by producing a pasty mixture comprising a polymerizable vinyl compound, a solvent capable of forming a gel with the vinyl compound in its polymerized state, and a filler and/or a substance which increases the viscosity of the solvent, adding a polymerization catalyst so as to initiate polymerization of the vinyl compound and contacting the pasty mixture with the object before gelformation while in contact with the object.  The vinyl compound may be methacrylic or acrylic acid or mixtures thereof with fumaric and maleic acids; instead of the acids, their salts, amides or hydroxyalkyl esters may be used. Preferably a monofunctional vinyl compound is used in admixture with a polyfunctional vinyl compound which may be a polyamide of acrylic or methacrylic acid and an organic compound containing at least two amino groups such as ethylene diamine or hexamethylene diamine, or may be triacrylformal.  The catalyst may be potassium persulphate or a redox system may be used; polymerization may take place under the influence of ultra-violet light.  The solvent may be water or glycerine or a mixture thereof.  Suitable fillers are calcium sulphate and carbonate, titanium dioxide, aluminium oxide, magnesia, magnesium carbonate, zinc oxide, filaments of linear polyamides, bentonite and talc, and substances which increase the viscosity of the solution may be silica gels, agar-agar, gelatine, dextrine, methyl cellulose, sugar, alginates and polyacrylates.

Abstract: 1495370 Remote control of receivers LOEWE OPTA GmbH 8 July 1976 [10 July 1975] 28396/76 Heading H3Q [Also in Division G4] A device is remotely controlled by transmitting a sequence of pulses separated by inter-pulse intervals having respective durations indicative of the values of corresponding digits of a data signal, a plurality of window pulses separated from one another by intervals equal to the minimum interpulse interval of the transmitted signal being generated in the receiver in response to the first pulse of the signal and being used for gating the signal to a decoder. A quartz crystal oscillator with divider stages is provided in transmitter and in receiver to control the timing, e.g. the window pulses are obtained by setting and resetting a flipflop in response to respective decoded counts of the receiver oscillator output. In the transmitter, a selected key actuation is encoded and inserted into a shift register which is shifted out with each bit resulting in one of two values for an inter-pulse interval in a pulse train which then gates a relatively high frequency pulse train to an infra-red (or ultra-violet or ultra-sonic) emitter. In the receiver, the inter-pulse intervals are evaluated by counting clock pulses, the data bits being loaded into a shift register under control of the window pulses, the shift register being reset if a pulse falls outside its window pulse. The transmitter sends the sequence of pulses repeatedly as long as the key is kept actuated. If the sequence in the shift register agrees with the previous repetition, and if the correct number of bits was received, the data is passed from the register to be decoded to control a radio or TV receiver, a bit being included in the data to select between radio and TV.
