Patent GB-787367-A (GB)
Title: Process for separating the constituents of mixtures by means of magnetic and electric fields
IPC: B03C1/00
Filed: 1955-11-23
Abstract: In separating constituents of material e.g. ore, the material is subjected to electric and magnetic fields simultaneously.  The material may be conveyed through a separating station on an inclined vibrating conveyer belt and is subjected to a magnetic field produced by a magnet below the belt above which an electrode producing a high voltage electric field is provided.  The electrode of opposite polarity may comprise the conveyer, the magnet, or an armature of the magnet.  The electrical supply for either or both field generating systems may be direct or alternating current.  When alternating current is employed for both systems, the phase relationship of the two supplies may be varied to regulate the interaction of the two fields.  The upper electrode may have a surface parallel to the conveyer.  Particles responding more strongly to the magnetic field are drawn downwardly on the conveyer, while the remaining particles are first attracted and then repelled by the upper electrode, a stream of air directed transversely of the belt carrying away these latter particles for collection separately.  Centrifuging or washing may be combined with the magnetic and electric actions and the material may be treated more than once in a series of stages.

Title: Evaluation circuitry for an x-ray apparatus
IPC: A61B6/03
Filed: 1975-08-12
Abstract: 1521084 X-ray absorption analysis SIEMENS AG 12 Aug 1975 [9 Dec 1974] 33623/75 Heading G1A [ Also in Division H4] In evaluation circuitry for an x-ray apparatus, an upstream signal I 0  from an amplifier 11 and a downstream signal I from an amplifier 8 are processed to give -y = log I 0 /I, from which a correction factor C is generated according to: C = 1 +  - y( - y -  - y 1 )(A 0  + A 1- y) for O#y#-y 1 , or  1 + (-y - -y 1 )(B 0  + B 1- y + B 2- y<SP>2</SP>) for -y 1 #-y#10, where, for an x-ray beam characterized by a normalizing spectral line at 51 KeV, the constants would have these values:  - y 1  = 4À45; A 0  = -0À035; A 1  = 0À0039; B 0  =-0À04; B 1  = -0À0126; B 2  = 0À00075. The ratio I/I 0  is then multiplied by C to give a corrected measure of the object density. An x-ray tube 1 having e.g. an anode voltage of 100KV, produces a polychromatic beam 4 of x-rays for transversely scanning a layer of an object 5, the beam 4 being rotatable, between scans, about an axis perpendicularly intersecting the scanning plane at a point 7 in the middle of the scan. The ratio of upstream to downstream intensities detected by respective detectors 10, 3, should ideally be an exponential function of the mass of material in the beam path; but for polychromatic radiation, differential absorbence characteristics of the test object 5 give rise to errors by reason of spectral hardening of the beam in its passage through the object, for which the correction factor C must be applied. The product CI, formed in a multiplier 15, is divided by I 0  at 9 and further processed by known methods to give a layer-image TV display at 12. Alternatively, Fig. 3 (not shown) a log quotient stage (16) produces -y = log I 0 /I and a function forming stage (18) produces a transformed log correction C<SP>1</SP> for adding to -y in a stage (17).

Filed: 1961-09-20
Abstract: 957,907. Transistor amplifying circuits. ENDEVCO CORPORATION. Sept. 20, 1961, No. 33702/61. Heading H3T. A differential amplifier comprises a pair of transistors 9, 10 with one electrode of each connected to a third transistor 16, the arrangement being such the third transistor constitutes a high impedance to attenuate unwanted unbalance signals introduced at the input to the two transistors so that only the desired differential signal is amplified. As shown, differential input signals are applied between the bases of transistors 9, 10 the common emitter current fed to transistor 16 remaining constant. Unwanted common signals applied in phase beteeen the input terminals 1, 2 and earth tend to change the common emitter current in conductor 19, but changes in this current are essentially prevented by the independent control of the emitter of the transistor 16. A number of such stages may be cascaded and the resistors may be replaced by reactive elements, provided correct biasing is maintained.

In an hydraulic braking system comprising a fluid pressure device such as a master cylinder B connected by a conduit C to an inlet port 42 on a brake applying fluid-pressure motor 24, the outlet port 44 of the motor 24 is connected to one end of a heat exchanger 48 mounted adjacent to and in parallel with the fluidpressure motor, the outer end of the heat exchanger being connected to the conduit C and a first check valve 46 is interposed between the latter connection and the inlet port 42 to prevent return flow from the fluid-pressure motor through the inlet port so that when the brakes are released the fluid is forced through outlet port 44 and through the heat exchanger 48 to prevent the fluid vaporizing in the circuit when prolonged braking occurs. A second check valve (not shown), may be inserted between the outlet port 44 and the heat exchanger to ensure that none of the flow during application of the brakes passes up through the heat exchanger to force hot fluid adjacent the outlet 44 of the wheel brake cylinders back to the wheel cylinders again. Conveniently the check valves may be incorporated in the casting of the wheel cylinder 24.

Title: Improvements in copying mechanisms for producing polygonal forms by turning, boring, milling, or grinding
IPC: B23Q35/10
Filed: 1922-12-15
Abstract: 212,654. CÚsar, J. Dec. 15, 1922. Lathes; copying and reproducing mechanism.- In a copying mechanism of the type described in Specification 147,978 the copying lever is mounted on a slide which moves in a plane at right angles to the work axis and which is arranged to oscillate a shaft connected by adjustable lever mechanism to impart the transverse feed to the tool-holder. The oscillations of the tool lever arm required to maintain the correct cutting relation between the tool and the work are effected from the copying lever through further lever mechanism. The mechanism is described with reference to lathes but is applicable also for boring, milling, and grinding. The templet comprising a hexagonal plate 3 is fixed to a hub which also carries a frame 4 provided with six studs corresponding with the edges of the workpiece. The hub of the pattern engages a slot 12 in a slide 11 which moves on a guide secured to an extension 9 of the headstock casing through which passes the templet driving spindle 1. The copying lever 14 having an arm 15 engaging the frame 4 is pivoted at 13 to the slide 11 and is further connected by links 17 to a slide 18 mounted on guides secured to a longitudinal shaft 20. The traversing slide 28 carries a cross slide 31 provided with a bearing for a shaft 34 which carries at one end a guide for a slide 37 which is connected by lever mechanism to the shaft 20. The other end of the shaft 34 carries the guide for the tool holding slide 39 the movements of the copying lever being thus transmitted to the tool through the above described mechanism. In order to operate the cross feed of the slide 31, the slide 11 is provided with an arm 43 mounted on a longitudinal shaft 47 rigidly connected to a parallel shaft 50. A lever 51 slides on the shafts 47, 50 and is slotted to receive a member 55 connected to a guide rod 58 pivoted at 60 to a bracket on the cross slide. An extension of the rod 58 is also adjustably secured to this bracket at 63. The scale of reproduction may be varied by adjusting the position of the member 55 by means of a screw 59. In operation, the screw 64 is first loosened and the tool slide 31 moved until the ratio of the distances from the machine axis of the pivotal axes of the tool lever arm and of the copying lever is equal to the linear scale of reproduction. The screw 64 is then tightened and the work piece 65 machined to the required size. For grinding or milling a rotatable shaft carrying a rotary cutter may be mounted on the tool-holder 39.
