Title: Process and apparatus for grinding grain into crushed meal and the like
IPC: B02C11/08
Filed: 1925-05-21
Abstract: 234,504. Schaefer, J. May 24, 1924, [Convention date]. Processes for reduction of grain.-In a process for the reduction of grain to fine grist by successively passing it between three pairs of rolls 3, 6, 10, the dimensions, spacing, and relative speeds of rotation of each pair of rolls are arranged so that the first pair effects a single longitudinal division only of the hulls by means of its fluted teeth, the second pair, which are smooth, separate the kernel from the hull and convert it into coarse grist, while the third breaks the coarse grist into fine grist between finely fluted teeth. Oscillating seives 4, 7 separate the parts at the various stages of reduction, the hulls being collected in a container 8, the fine meal in a container 9, and the fine grist in a container 11. The rolls 3, which are driven at speeds approximately in the ratio 2 to 1, are 100 millimetres in diameter and are spaced about 1 millimetre apart; the rolls 6 are driven at equal speeds, and their diameters and spacing are the same as the rolls 3, while the rolls 10 are 100 millimetres in diameter, have a speed ratio of 2 to 1, roll spacing 0,2 mm., and the teeth edges engage three times with the particles of the grist before they are released from the rolls. The grains are fed to the rolls 3 from a hopper 1 by a feed-roll 2.

Patent GB-347884-A (GB)
Title: Improvements in or relating to projectiles particularly for sporting guns
IPC: F42B7/04
Filed: 1930-05-01
Abstract: 347,884. Projectiles ; shot charges. LAFITE, M. G., 215, Rue Americaine, Brussels. May 1, 1930, No. 13422. [Class 9(i).] A projectile containing small shot for sporting guns and which may be adapted to indicate the path of the projectile in the air comprises a case which contains a charge of shot or the like and has, in combination, a restricted aperture at its forward end and a retarding device associated with its base. Due to the retardation of the case during flight, the shot charge escapes by its momentum through the aperture and a dense distribution of the shot is ensured. The projectile illustrated comprises a hollow case 1, Fig. 9, which is preferably of elastic material, such as rubber, and is adapted to contain a charge of shot (not shown). The nose of the case is substantially conical and is provided with an aperture 5. A felt or other elastic wad 9 is secured to the base of the case by twine or similar connection 10 and supports a retarding device comprising a tuft 8 of silk, twisted wool, or the like. The connection 10 passes through an aperture 6 in the case and is secured to a rigid washer 3. The wad 9 is slightly larger in diameter than the cartridge case 11. On discharge, the wad 9 and tuft 8 expand, as shown in Fig. 7, and the tuft retards the case 1, whereupon the shot charge, which is not influenced by this retardation, escapes through the aperture 5. The wad 9 may be of rubber or woven material, and in the construction shown comprises two layers of felt and an intermediate spring steel plate, this arrangement being sufficiently rigid to prevent the yielding of the wad to the wind pressure. A number of steel wires may be incorporated in the silk or wool of the tuft 8. In modifications, the tuft may be of linen or woven material, hair, bristle, rubber, metal wires, or resilient or jointed blades or laminae which will expand compulsorily and remain expanded notwithstanding the air pressure. In a further modification, Fig. 10 (not shown), the retarding device is in the form of a parachute. The size of the aperture and of the shot, and the conicity of the head of the case, may be varied to suit the various purposes for which the projectile may be employed. The retarding device may be of such size as to be visible during flight while the elements employed may be fireproofed, and painted, dyed, or rendered phosphorescent, luminous, or brilliant to ensure the visibility of the device under all atmospheric conditions.

Title: Optical data recording
IPC: G11C13/04
Filed: 1969-03-14
Abstract: 1,218,331. Holography. INTERNATIONAL BUSINESS MACHINES CORP. March 14, 1969 [April 9, 1968], No.13456/69. Heading G2J. A method of holographically recording data comprises bringing together at a recording medium 12 a reference beam 13 and a data beam 10, wherein the transmitted part of the reference beam 15 is redirected through the medium 12 at a location continuing to receive the data beam. The redirected reference beam may be caused to retrace its original path through the medium, or it may return along its original path in the reverse direction. In reconstruction the reference beam follows the same paths as the original reference beam 13 and consequently forms two coincident vertical images at the location of the original object or data source. The transmitted part of the beam 15 may be redirected by a plane mirror 16. If the mirror and reference beam source, laser 14, are interchanged real images are set up. The data record can be used to align optical apparatus by comparing the coincidence of the real or vertical image and the original object. In an alternative embodiment the recording medium is located between a pair of concave mirrors, one of which has an aperture for passage of the reference beam. This beam is caused to re-pass through the medium several times, always from the same side, the number of passes being determined by the resolution of the medium. A further embodiment replaces each concave mirror by two orthogonal reflecting surfaces, the transmitted part of the reference beam repassing the recording medium alternately through opposite sides.

Title: Improvements relating to change speed gear mechanism
IPC: F04B49/24
Filed: 1961-04-17
Abstract: 973,279. Change-speed control. HUMBER Ltd., and J. D. BATTEN. April 16, 1962 [April 17, 1961], No. 13803/61. Heading F2D. In a three-element epicyclic change-speed gear unit changeover from direct to over-drive is effected by actuators 28 supplied with pressure liquid from an input-driven reciprocating pump 32, the discharge from which is progressively reduced, by reducing the effective area of its inlet port 56, as the pressure rises above a predetermined value. As shown the sun-wheel 16 is freely mounted on the input shaft 13, to which the planet carrier 12 is secured, the annulus 14 being attached to the output shaft 19. A cored friction member 20 splined to sun-wheel 16 is normally urged by springs 25 into engagement with annulus 14 to lock the gear for direct drive, the pressure liquid supplied to actuator 28 overcoming springs 25 to move member 20 against a fixed member 26 to hold sun-wheel 16 for overdrive. Pump 32 has inlet and outlet ports 56, 60, the discharge from the latter being controlled by a solenoid valve 30. The pump plunger 50 is operated by a cam 33 on shaft 13 and works in a cylinder sleeve 40 loaded by a compression spring 42. When the delivery pressure rises above the predetermined value a non-return valve 45 in the lower end of cylinder 40 is opened and the pressure acting on the end lifts the cylinder against the force of spring 42 so that the effective area of inlet port 56 is reduced. The upper end of cylinder 40 houses a piston cap 52 for delivering low pressure lubricant to an axial supply passage 66 in shaft 13. The pump unit forms the subject of Specification 973,280.
