Title: Improvements in and relating to nut cracking machines
IPC: A23N5/00
Filed: 1930-08-01
Abstract: 360,040. Nut-cracking m a c h i n e s. REPP, C. B., 949, Park Avenue, Plainfield, New Jersey, U.S.A. Aug. 1, 1930, No. 23247. [Class 59.] In a nut-cracking machine one or more power driven heads 11, Fig. 4, each having a plurality of chisel blades or wedges 15, 16 and 17, 18, respectively engaging the ends and sides of a nut, are positioned to engage in succession a nut or nuts carried on a travelling carrier unit 23, each nut being subjected to the action of the blades in such a manner as to fracture the shell by a lever action about that part in contact with the carrier. The head 11 is mounted on a crank pin 12, the shaft 14 of which is driven by a pinion 63 in gear with a wheel 62 mounted on a drum 35, Fig. 1, which drives the endless carrier 23. The head 11 is maintained in a vertical position during the rotation of the crank by a link 54 connected to a crank 52 of the same radius as the crank 13 and driven at the same speed by chain gearing 57. The endless carrier 23 is led over drums 35, 32, the drum 35 being driven by worm and wormwheel 58, 59. The drum 35 is provided with projections 36 which project through the carrier and ejects the cracked nuts therefrom. The carrier is jointed and has upstanding curved projections to receive a nut, the bottom of the recess so formed being provided with a short, transverse, blade 29 and two longitudinal blades 31. The nuts are fed down a shoot 43 and a shield 45, which covers the blades 29, 30, 31, facilitates their reception by the carrier by which they are carried under the head 11. The rotary movement of the head allows the blades 15 .. 18 to engage the nuts before they are immediately under the dead-centre so that the greatest pressure is applied in the latter position. The carrier is supported on rollers 38, 39, 40 at this point so that the blades 29, 30, 31 act on the underside of the nut. A stripper blade 41 projects between the blades 15 .. 18 and prevents withdrawal of the nut with the head. The nuts are discharged over the end of the drum 35 and fall into a casing 46 containing revolving beaters 48 which project the cracked nuts on to an impact plate 49 and thereby separate the kernels from the shells. These fall on to a conveyer belt 50, which is inclined laterally so that the kernels fall off into a receptacle whilst the rough shell adheres to the conveyer band and is discharged into a receptacle.

Filed: 1927-09-07
Abstract: 295,519. Hasselkus, J. W., and Richmond, G. A. Sept. 7, 1927. Lenses. - Photographic objectives, having front and back combinations, each comprising a double convex lens and a double-concave lens cemented together and a single positive meniscus lens on the diaphragm side of the doublet with its concave surface directed towards the diaphragm and separated from the doublet by an air space, have the refractive indices of the component lenses in ascending order of magnitude commencing with those nearest the diaphragm. The front doublet is of greater negative power than the back doublet, while the front meniscus is of greater positive power than the back meniscus in order to overcome comatic defects. The front or back combination if placed on the side of the diaphragm remote from the source of light with its meniscus towards the diaphragm is corrected for astigmatism by and for itself. Numerical data are given for an objective having a field of view of 70‹ and an aperture of F/4, which gives an astigmatically-corrected field free from spherical, zonal, chromatic and comatic aberrations.

Title: Improvements in or relating to process for the chlorination of saturated aliphatic hydrocarbons, apparatus therefor and the products resulting therefrom
IPC: C07C19/10
Filed: 1939-08-22
Abstract: 532,218. Chlorinating hydrocarbons. STEVENS, A. H. (Dow Chemical Co.). Aug. 22, 1939, No. 24177. [Class 2 (iii)] [Also in Group III] A saturated aliphatic hydrocarbon containing less than 7 carbon atoms in the molecule is chlorinated by subjecting a mixture of the hydrocarbon in gas phase with chlorine to the action of light in a vapour space maintained over a body of substantially inert liquid, having an appreciable vapour pressure at the working temperature. As a modification a mixture of the hydrocarbon, chlorine and an anhydrous gas, which includes a chlorinated hydrocarbon and which is substantially inert to the chlorine and has an appreciable partial pressure in the mixture, is subjected to the action of light. Alternatively, as applied to a mixture of such hydrocarbons, light acts upon a gaseous mixture containing the hydrocarbons, a controlled amount of chlorine and an anhydrous gas which includes a chlorinated hydrocarbon, and which is substantially inert to the chlorine, andis present in an amount sufficient to suppress any tendency of any one of the hydrocarbons to be chlorinated destructively to carbon and hydrochloric acid. In an example, Fig. 1, of the first arrangement, methane from a pipe 7 and chlorine from a pipe 6 are supplied through a pipe 8 to jets 71 of a header 42 and rise in bubbles through an inert liquid, e.g. carbon tetrachloride, preferably maintained at a raised temperature in a vessel 9 while subjected to intense light from a source 15 within a well 14 and the reaction products pass from the gas space 17 through a line 18 to a condenser 19 and separator 61. The temperature of the condenser 19 is such that substantially all the components of the mixture are liquefied except the hydrochloric acid, which passes off through line 21. The liquid from separator 61 passes through line 62 to a rectifier 63 from which chlorine and partially chlorinated methane are taken off at 66 for fractionation and carbon tetrachloride is delivered through line 64 to the vessel 9 or to storage. In a modification the header 42 is disposed immediately above the surface of the inert liquid with the jets 71 directed downwards so that the gaseous mixture impinges on the surface of the liquid and thus becomes saturated with the vapour. An arrangement is also illustrated in which no inert liquid is used but a mixture of methane, chlorine and carbon tetrachloride is supplied to a header such as 42 in which the jets 71 are directly upwardly. The carbon tetrachloride may be replaced by. for example, hexachlorethane or octachloropropane.

Abstract: 1,239,833. Advancing mine roof support systems. BERGWERKSVERBAND G.m.b.H. 22 May, 1968 [31 May, 1967], No. 24447/68. Heading E1P. [Also in Division F2] In an advancing mine roof support assembly for a longwall comprising a series of frames each connected to the conveyor by a double-acting jack and arranged in groups for automatic control to maintain alignment relative to adjacent groups, each group of frames has a series of auxiliary frames whose incremental advance is determined relative to a guide frame. The control system includes a group switching arrangement which in predetermined sequence passes control pulses from the auxiliary frames to a comporator control to which the guide frame is connected in parallel, see Fig. I (not shown). The comporator control for each group of frames comprises a cam mechanism 40 actuated by two jack units 43, 45 operating in opposite directions. An input 21 to the control leads from the group switching arrangement whilst pulses from the guide frame are fed thereto via a line 33. An input pulse fed to line 21 passes through a valve 48 to a line 21a thereby effecting a one step advance of the associated auxiliary frame, the valve then being closed by the unit 43. The second step advance of the said frame is effected by a further control pulse fed through the line 21 and a valve 49 until this valve in turn is closed by further rotation of the cam mechanism by the unit 43. Pulses fed from the guide frame to line 33 rotate the cam mechanism in the opposite direction to open the valves 51, 52 in sequence and close the valves 48, 49; the sequential opening of the valves 51, 52 causing two step advance of the next auxiliary frame of the group via a line 32. The arrangement is such that the auxiliary frames can only beat the guide frame by a maximum of two steps. Logic components of electrical, pneumatic or hydraulic design may be interconnected in the control line of the system and to this end line 33 leads to a. computerised control for the whole system.
