Title: Improvements in and relating to the cleaning, husking and opening up of cereals
IPC: B02B3/00
Filed: 1930-11-10
Abstract: The husks of cereals which have been separated from the kernels in a wet process of reduction are stated to be useful in the cellulose industry, more particularly as the raw material for the manufacture of celluloid and of artificial silk.ALSO:Cereals are reduced by stirring them up in a small volume of water at 60-65 DEG  C. for about 15 to 20 minutes so that a portion of the husks becomes separated before the kernels swell in the water and can be separated off preferably by flotation in cold water. The grains are then dried preferably by warm air and the remainder of the husks removed.  The kernels are ground to flour, and the two portions of husk mixed together.  The separated husk are used as the raw material in the cellulose industry more particularly in the manufacture of celluloid and artificial silk.
Patent GB-854530-A (GB)
Title: Improvements relating to variable pitch propellers
IPC: B64C11/40
Filed: 1958-10-22
Abstract: 854,530. Variable pitch propellers. UNITED AIRCRAFT CORPORATION. Oct. 22, 1958 [Oct. 22, 1957], No. 33857/58. Class 114. In a variable pitch propeller the means for changing the pitch of the blades is regulated by a governor responsive to functions of propeller speed and acceleration. A pump supplies fluid via line 42 to a governor 24 thence via low and high pitch lines 58, 60 to a pitch change motor. The governor comprises a flyweight unit 30 rotating with the propeller to act on a pilot valve 36 in opposition to the force of a spring 38, and a pitch change valve 40. When the propeller rotates in an underspeed condition spring 38 overcomes forces of flyweight 30 and moves pilot valve 36 upwardly. Pressurized fluid acts through pump line 42 annulus 44, ports 46, annulus 68, line 70 and annulus 66 on surface 64 to lift valve 40 which places line 42 into communication with low pitch line 58 to cause the motor to decrease the pitch of the blades. Thus in a propeller underspeed condition valve 36 and hence valve 40 move upwardly at a velocity proportional to propeller acceleration, thereby reducing the volume of a chamber 74 between stationary wall 76 and skirt 78 of valve 40 and causing fluid to be forced through a restriction 82, the pressure drop across this restriction thus being proportional to propeller acceleration and acting through sump line 72, annulus 86, ports 88 and 90 to chamber 84, the pressure fluid in chamber 74 acting via aperture 87 and chamber 85 to apply a lifting force on valve 36 proportional to the propeller acceleration. When the propeller rotates in an overspeed condition, flyweights 30 move outwardly to force valve 36 downwardly. Pressure fluid flows via annulus 44, port 46, annulus 48, aperture 50, annuli 52, 54 and 56 to act on surface 62. Area of surface 62 is a proportion preferably one half, of that of surface 64. Pressure in annulus 66 is bled through annulus 68 to sump line 72, and valve 40 is therefore moved downwards with the pilot valve 36. The volume of chamber 74 increases at a rate proportional to the velocity of valve 36 and hence the acceleration of the propeller. This reduces the pressure in chamber 74, aperture 87 and chamber 85, causing an inflow from line 72 through the restriction 82 so that a force acts in annulus 56 proportional to propeller velocity to move valve 36 downwards. For emergency propeller feathering purposes, fluid may be passed through line 102 into chamber 104 to move valve 40 downwardly. Specifications 514,725, 526,100, 683,906, 754,095 and 777,572 are referred to.

Title: Improvements in or relating to devices for controlling the raising and lowering of agricultural implements particularly ploughs
IPC: A01B63/10
Filed: 1946-11-19
Abstract: 619,090. Hydraulic machines. REGIE NATIONALE DES USINES RENAULT. Nov. 19, 1946, No. 34253. Convention date, Oct. 11, 1945. [Classes, 69 (ii) and 135] [Also in Group I] A hydraulic power-lift device for tractormounted implements includes a piston 15 movable in a cylinder 16, the piston being connected to the implements through a bell-crank 12, and a pump 17, which feeds oil to the cylinder through a distributer formed of two members 18, 19, sliding, one inside the other, in a casing 26 in such a manner that relative movement between the sliding members regulates the flow of oil to the cylinder. The casing is divided into four chambers 26<1>-26<4> and the sliding member 19 comprises a sleeve having orifices 30-35 by means of which the chambers are put into intercommunication. The sliding member 18 comprises a double piston 18<1>, 18<2> which is movable by a lever 20 to cover and uncover the various orifices. The sleeve 19 is connected to the bell-crank 12 through a lever 22, pivoted at A, and a rod 23. To raise the implements, oil is pumped from a reservoir, through a pipe 27, orifices 30 and 31, pump 17, orifices 32 and 33, and outlet pipe 26<5>, into the cylinder 16. The resultant movement of the piston 15 moves the sleeve 19 so that the orifices 30-33 are covered, and the tools remain raised. To lower the tools, the double piston is moved to the left, thus uncovering the orifices and permitting escape of oil from the cylinder 16. The device also operates as a depth-regulating device, since variations in the ground resistance to the tools are transmitted as variations in oil pressure to an auxiliary spring-loaded piston 24 carrying the fulcrum A of the lever 22. This causes movement of the sleeve in such a direction as to admit oil to, or permit its expulsion from, the cylinder 16.

Filed: 1927-12-19
Abstract: 282,446. Silvano, E., and Cerri, V. L. Dec. 17, 1926, [Convention date]. Oils, extracting by solvents.-In a process for washing or extracting material in a soft or granular condition, such as seed or oil cakes, the material is disposed in a thin ribbon sandwiched between mating conveyers and conveyed in the direction of the length of the ribbon, and washing or extracting liquid is passed through the material in the direction of the thickness of the ribbon. The liquid is preferably passed through the material successively in opposite directions, and the general flow of the liquid is opposite to that of the material. Suitable apparatus for carrying out the process comprises two endless belts 1, 2 having a cross-section as shown in Fig. 2, and acting as filters. The material is fed from a hopper 20 on to belt 1 and is enclosed between the belts at roller 4 in a space as indicated in Fig. 3. The belts convey the ribbon of material to the surface of a perforated drum 7 as shown in Fig. 4, and washing &c. liquid is passed into the drum at 8 and passes through the perforations 22, Fig. 4 and through the material enclosed between the belts and exits at 10. The material is then washed successively in opposite directions by means of reversing rollers 12, 12<1>, 12<11> and washing drums 11, 13 and 14, and is finally removed from the belts by brushes 6 and falls .into a hopper 24. The passage of the liquid through the material may be effected by pressure or suction instead of gravity, and fresh liquid entering the drum 14 may pass out at 10<11> to drum 13 and so on, to produce a continually enriched washing or extracting liquid. The washed material may be dried before or after leaving the belts, and the apparatus may be enclosed to prevent losses due to evaporation &c.

Abstract: 1,022,418. Light modulation. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 12, 1962 [Sept. 15, 1961], No. 34835/62. Heading H4F. [Also in Division H1] A beam of electromagnetic radiaton 5 to be modulated is passed through a semi-conductor body 1 which is transparent to the radiation, has an electrical connection 2 so that majority carriers may be supplied to and withdrawn from the body and is associated with and insulated from a modulating conductor 3 whereby the concentration of majority carriers in a surface layer 9 may be varied, the arrangement being such that the beam is reflected within the body at the surface associated with the layer and the concentration of majority carriers in the layer is controlled so that it exceeds the intrinsic concentration. By virtue of the invention the modulation is mainly due to absorption by majority carriers, the effect due to minority carriers being negligible, whereby the maximum permissible modulation frequency is increased. Preferably, the control of majority carriers is such that it exceeds the concentration of majority carriers in an adjacent part of the body. The impurity concentration in the surface layer may be made greater than that in the remainder of the body so as to provide an increased concentration of majority carriers for control by the modulating conductor- Arrangements for increasing the degree of modulation by multiple reflection are described with reference to Figs. 2-5 (not shown). A plurality of modulating electrodes may be provided to permit modulation of the beam by a plurality of different control signals. The semiconductor body may comprise P-type germanium with the concentration of holes in a surface layer increased by diffusing in indium atoms. Aluminium comprises the modulating conductor and is insulated from the body by a layer of silicon monoxide. Reference is also made generally to the use of N-type material. A silicon body provided with a silicon monoxide insulating layer may have the modulating conductor formed by a liquid electrolyte of N- methylacetamine with 0À04N potassium nitrate. Alternative materials for the insulating layer may comprise: air, mica, tantalum pentoxide, ceric oxide and strontium titanate.

Abstract: 1,223,175. Anionic lactam polymerization. ALLIED CHEMICAL CORP. 22 July, 1968 [21 July, 1967; 24 July, 1967], No. 34880/68. Heading C3R. Lactams are polymerized in the presence of an alkali metal or alkaline earth metal lactam salt as catalyst and as co-catalyst a compound of formula wherein either X is O and Y is a 5- or 6-membered ring containing nitrogen which bonded to the rest of the molecule by a direct link to a ring nitrogen atom or through a sulphur atom to a ring carbon atom or X is S and Y is -S-CO-(O) m -R where R is a hydrocarbon radical and m is 0 or 1. The lactam may have 6-12 carbon atoms, e.g. epsilon - caprolactam. A lactam-catalyst mixture may be prepared by adding to the lactam sufficient of an alkali metal or alkaline earr,h metal or basic compound thereof, e.g. LiAlH 4 , to convert 0À1-5 mole per cent of the lactam to lactam salt and heating the mixture above the m.p. of the lactam. The process should be carried out under anhydrous conditions, i.e. less than 50 p.p.m. of water or other proton donors should be present. The product may be stored or reacted immediately with the co-catalyst. The co-catalyst may be 1 - (2 - benzoxazoyl)benzotriazole, di - (2 - benzoxazolyl) thioether, 3<SP>1</SP>-(2<SP>1</SP>-benzoxazoyl)-3,5- dimethylpyrazole, 3 - (2<SP>1</SP>- benzoxazoyl)- benzoxazoline - 2, 2 - (ethoxycarbonylthio)- benzothiazole, 2 - benzoylthiobenzthiazole or 2 - (n - butyloxy - carbonylthio)benzothiazole. They may be prepared by reacting the sodium salt of 2 - mercaptobenzothiazole with an equimolar amount of a compound of formula R(O) m COCl in a solvent, e.g. xylene, or heating 2 - chlorobenzoxazole with an equimolar amount of a compound of formula YH, where H is an active hydrogen atom, under anhydrous conditions, in a solvent, e.g. xylene, at a temperature between 50‹ C. and reflux temperature until HCl evolution ceases. 0À1-10 moles of co-catalyst may be used per mole of catalyst and 0À05-1À5 moles of co-catalyst may be used per mole of lactam. The reaction temperature e.g. 110-215‹ C. may be between the m.p. of the lactam and the softening point of the polymer so that the product is a solid shaped article. Fillers and plasticizers may be added to the reaction mixture. In Example 8, the lactam is polymerized partially in the presence of the catalyst only before the co-catalyst is added.
