Title: Improvements in shovelling and loading machines
IPC: E02F3/348
Filed: 1950-02-17
Abstract: 669,713. Scoop arm machines. SOC. TECHNIQUE POUR L'INDUSTRIE MINIERE S.O.T.I.M. Feb. 17, 1950. [Feb. 17, 1949] No. 4200/50. Class 68 (i). [Also in Groups XXX and XXXII] In an excavating and load handling machine the bucket 4 is pivoted at 15 to arms 26 which are pivoted to the machine frame 2 at 17 and are oscillated by hydraulic jacks 18, rotary motion of the bucket relative to the arms 26 being effected by flexible chains 24 cooperating with cam elements 16 rigid with the bucket and operated by a second pair of jacks 22. In operation the jacks 18, 22 are selectively controlled to effect movement of the bucket from the full line position to the upper chain line position, the cams 16 being so shaped that the bucket is rapidly accelerated at the end of its lifting movement so that the material is thrown onto a conveyer 3. This conveyer is adjustably supported on the machine by a jack 7 and comprises a hopper 21 and a belt 8, this belt being longitudinally grooved on its under surface, as shown in Fig. 3, to engage grooved pulleys 9 and having material engaging projections 8a on its upper surface. The conveyer is selectively driven at two speeds by a hydraulic motor, not shown, the slower speed being also an intermittent drive. This drive is initiated by depressing a pedal 27, Fig. 4, so that a piston 28 moves downward and allows fluid to flow along conduit 26 until, after a predetermined delay controlled by the setting of a needle valve 36 in a closed hydraulic circuit, a spring 30 returns the pistons 32, 28 to their initial position and so stops the conveyer drive until the pedal is again operated. The conveyer and hopper are designed to accumulate a truck full of material during the period during which the truck is not located under the discharge end of the conveyer, by use of this slow intermittent drive. In modifications (not shown), jacks 18, 22 are eithers crew or rack actuated, or they may be replaced by cables and winches.

Title: Improvements in photographic sensitive papers
IPC: G03C1/74
Filed: 1943-03-15
Abstract: 564,272. Photographic sensitive material. KODAK, Ltd. (Eastman Kodak Co., and Staehle, H. C.). March 15, 1943, No. 4224. [Class 98 (ii)] [Also in Group VIII] A long length of a photographic light-sensitive material is made by continuously feeding a length of a thin non-fibrous flexible film support over a roller or rollers or the like (e.g. a portion of the periphery of a drum) during which it is inseparably coated on one side with a gellable silver salt emulsion and then the film so coated is fed to a roller or equivalent device to which is also fed a length of paper which is caused to adhere permanently to the film on the opposite side to the emulsion layer while the emulsion is in the state of a set gel, and the gel is dried. The film may be from 0.0005-0.001 inch thick, or even up to 0.002-0.003 inch thick, and may be of cellulose nitrate, acetate, or other esters. The paper may be waterproofed by impregnation with a dilute solution of a cellulose ester or with an aqueous resin dispersion, e.g. aqueous dispersions of an acrylic resin, n-butyl methacrylate, or polyvinyl acetate. The paper support may comprise a metal foil between two sheets of paper. The film may be adhered to the paper by means of a dilute cementing solution and the other side of the paper coated with a waterproofing solution. In an example, thin cellulose acetate film subbed with a composition comprising gelatine, low viscosity, cellulose nitrate, acetone, methanol, and acetic acid is fed from a roll 1 on to a cooled rotating drum 6, and is coated at the hopper 5 with gelatino silver halide emulsion. The film then passes to the roller 8 together with the paper sheet, previously coated with a baryta-gelatine mixture and at the hopper 12 with a substratum .of the composition previously specified. The composite material then passes to a drying chamber. In a modification, the substratum layer on the film is omitted, so that the emulsion layer may be stripped before or after exposure or before or after development. Specification 25981/03, [Class 98], is referred to.

Abstract: 962,644. Discharge apparatus. ACADEMIA REPUBLICII POPULARE ROMINE. Feb. 5, 1960 [Feb. 6, 1959], No. 4248/60. Heading H1X. Spectral analysis discharge device comprises a H.F. oscillator coupled to a base electrode to cause a H.F. torch or brush discharge to be emitted therefrom and means for superimposing on the H.F. torch discharge a continuous, intermittent or glow direct current discharge which can be maintained after the extinction of the torch discharge. The device comprises a coil 1 and condenser 2, one plate of which carries a pointed base electrode 3 for the torch discharge and the other plate of which, preferably shaped as a ring or cylinder, forms an auxiliary electrode for the torch discharge and concentrates the electric field. The coil 1 and condenser 2 form a resonant circuit A, the resonant frequency of which is about or above 10 mc/s. A D.C. supply circuit B comprises a movable electrode 4, chokes 5, 5<SP>1</SP>, and a D.C. source 7. The chokes 5, 5<SP>1</SP> are connected respectively to the mid-point of the coil 1 and to the electrode 4. If spark discharges are to be superimposed on the torch discharge one or more adjustable condensers 6 are connected across the ends of the chokes 5, 5<SP>1</SP>. A coupling circuit C includes two capacitors 8, 81 connected one to each end of the coil 1, two coaxial lines 9, 9<SP>1</SP> and a coil 10 coupled to an oscillator, of frequency about 10<SP>7</SP> c/s., tuned to the resonant frequency of the resonant circuit. Alternatively, inductive coupling could be used. The intensity of the direct current discharge may be varied by changing the voltage or by changing the distance between the base electrode 3 and the movable electrode 4. Alternanatively, the intensity of the torch discharge may be adjusted. The device operates, under certain conditions of the superimposed direct current, also as a direct current glow discharge, if the torch discharge is interrupted during the superimposed discharge. The glow discharge can be adjusted by changing the direct current flowing through the discharge. Gaseous substances can be introduced into the discharge through a tube and solutions through an injecting nozzle from an atomizer. Solid substances for analysis can be used for the base electrode 3. Means can be provided for preventing disturbances by air currents.

Title: Improvements relating to machines for the arithmetical calculation of the indications shown on perforated cards
Filed: 1928-02-10
Abstract: 285,456. Tauschek, G. Feb. 17, 1927, [Convention date]. Statistical machines.-In a record-card-controlled machine means are provided whereby the results of a calculation registered on the totalizer counting-mechanism, e.g. the wages due to workmen, can be perforated on the card or on the last of a series of like cards. Two forms of the device are shown, the numerical values being represented in the first form by a succession of perforations and in the second form by the position in the column of a single perforation. In the form with electrical sensing means, Fig. 1, each perforation sends an impulse to an electromagnet 3 which through a pawl 4 operates an actuator rack 5 and totalizer pinion 6. After each item has been registered the totalizer frame 7 is rocked to free the actuator racks which under the control of a spring 9 return to normal position whereupon the totalizer pinions are again thrown into engagement for subsequent actuation. Each actuator rack 5 is adapted to cooperate with a gear 15 meshing with a rack on a member 14 provided with a ledge 16 movableover a set of spring-controlled punches 10. In a total-taking operation the totalizer is disengaged and the racks 5 are raised to their uppermost position by a rod 20 whereupon. the totalizer is moved into engagement again and the pawls 4 and 8 are withdrawn. At the same time levers 19 are brought into the path of the zero-stop cams and the pinions 15 into engagement with the actuators 5 so that upon the action of the springs 9 the actuators are moved until the totalizer pinions are set to " 0 " and the members 14 are set to positions over the punches 10 according to the numerical values. The members 14 are interconnected by rods 17 on toggle levers 18 which when straightened cause the punches to perforate the record-card or strip on the matrix plate 13. In the second form shown in Fig. 2 for dealing with cards having single perforations in the columns the perforations felt cause the setting of pins 21 into the path of stops 28 on the actuator racks 23 which are permitted to move, when the levers 26 are lowered by operation of a frame 24, to actuate the totalizer 31. In total-taking operations the totalizer 31 is thrown out of engagement and the actuators are lowered to their limiting position. The totalizer is then brought into engagement and the frame 24 returned so that the levers 26 raise the actuators until the totalizer pinions are at the " 0 " position. Upon operation of the toggle levers 32 a plate 30 moves the stop 28 to force the appropriate pins 21 to perforate the card.
