Title: A method of increasing the starch content of raw fodder
IPC: A23K3/03
Filed: 1952-07-16
Abstract: The starch content of protein-deficient raw fodder is increased by forming it into a mass deprived of oxygen, acidifying the mass to a pH value of about 5 and then ensiling it.  Steamed potatoes may be pulped and acidified simultaneously and then stored in a sealed silo. Half-ripe maize cobs, stripped of their bracts but not of their axes, may be bruised or compacted and acidified simultaneously and then ensiled in sealed tubes of synthetic resin.

[Class 39 (i).] A high-tension device, such as a Rontgenray tube, having no appreciable gas filling, and a cathode structure comprising an incandescent filament and designed to throw a focussed beam of electrons on the anode, is so arranged that the beam of cathode rays lies between two preferably parallel surfaces, of which that of the anode extends laterally from the beam so far that it is intersected by the longest paths of secondary electrons emitted by the anode. In one form the surfaces are parallel and consist of the anode 11, Fig. 4, and the focussing member 13. It is stated that the diameter of the anode must be at least equal to the diameter of the focal spot plus four times the distance between anode 11 and member 13. In another form the focussing member is convex and the anode target is situated at the bottom of a cavity covered by a concave plate parallel to the focussing member. A formula for the angular aperture of the concave plate is given. The walls of the cavity are apertured to permit of the emission of X-rays. In the device shown in Fig. 4 part of the focussing member 13 is removed and replaced by thin foil 21 of ferro-chromium or aluminium ; or the wall of member 13 may be reduced in thickness at this point by hammering or grinding. The invention may be applied to rectifiers as shown in Fig. 6. The filament 24 is mounted inside a focussing member 25. The anode 23 and focussing member 25 are enlarged by plates 26 and 27 which extend, beyond the edge of the cathode beam, to at least double their mutual distance. The minimum anode dimensions are deduced mathematically for plane and spherical surfaces.

Title: Improvements in lubrication of internal combustion engines
IPC: F16N19/00
Filed: 1931-06-26
Abstract: 376,480. Force-feed lubricating. ELLOR, J. E., Grandell, South Drive, Chain Lane, Mickleover, Derby. June 26, 1931, No. 18541. [Class 12 (iii).] In a lubricating system for an internalcombustion engine wherein oil is delivered from the engine sump by a pump through a pipe b<7> into a chamber b, whence it is supplied to the engine through a filter b<3> and pipe b<2> by another pump, the chamber b is constituted by one portion of a divided tank and is in communication through small holes in the dividing, wall with the other portion a containing a reserve supply of oil so that the oil levels in the two portions are the same. By thus restricting the size of the chamber b through which the oil circulates, the oil in circulation is quickly heated up when the engine is started. As shown, the chamber b in the form of a vertical cylinder projects into the tank a, communication being established through holes c. Oil discharged through the pipe b<7> spreads over a diaphragm b<8>, whereby trapped air separates out and passes into the vented tank a through apertures b<6> in the top of the chamber b while the oil drops into the latter through apertures in the diaphragm. In another form, the chamber a is arranged within the tank b and the oil discharged through the pipe b<7> runs down an inclined trough in the upper portion of the tank so as to separate out any trapped air.

[Class 60] A stropping-device for safety razor blades comprises a body carrying a rockable blade-holder which is rocked by a finger-held operating part to bring the trailing edge of the blade into contact with the strop. The device comprises a body 1 of U-shape to which is secured, by lugs 17, a guard frame 2 formed by bending a metal stamping into the shape shown in Fig. 4. Pivoted at 6 in the body 1 is a U-shaped carrier 7, the movement of which is limited by stops 8 on the body 1, and pivoted at 9 in the carrier is a bar 10 connected to an enclosing handle 20 by a rod 19 and screws 21. The bar 10 has a reduced end 11 engaging in a slot 12 in a bar 13, which is secured to the trunnion 14 of a blade-holder 3 comprising two parts secured to the trunnion to hold the blade between them, one part normally springing away from the other part. The blade-holder is rockable in the guard frame on the trunnion 14 and a second trunnion formed by reduced ends 26, 26<1> of the two parts of the holder, the ends being received by slots 28, 28<1> in the frame ; the ends and slots are arranged so that one part only of the holder can be lifted for insertion &c., of a blade. The holder is retained in closed position by a clip 24 pivoted at 23 to the frame 2. In operation, the handle 20, held by the fingers, is moved to press the blade 4 on the stop 5 and to move the device along the strop, this action causing the end 11 to move to the bottom of the slot 12 and rock the bar 13, thereby turning the blade to bring its trailing edge on to the strop. The other faces of the blade edges are treated by turning over the device. In a modification, the body 1 is secured to the handle and the bar 10 is moved by finger pieces extending through slots in the handle.
