Abstract: 916,035. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 30, 1959 [Jan. 31, 1958], No. 3383/59. Class 98 (1). [Also in Group XL (a)] An X-ray spectrograph employs an annular detector (see Group XL (a)) specially designed to detect the characteristic radiation of elements of low atomic number such as magnesium (atomic number 12). Fig. 8 shows a combined spectrograph and spectrometer in which primary X- rays, preferably monochromatic, generated by a tube 48 strike a specimen 9 generating characteristic secondary X-rays which enter the counter 1 through a window 8. The primary X-rays diffracted by the specimen are scanned by a conventional detector 49 mounted on a circular scale 50 or goniometer and adapted to rotate with the specimen about an axis 51 at twice the angular speed of the specimen. Collimating slits 52 limit the beam of diffracted X-rays entering the detector 49. A crystal monochromator may be interposed between the specimen 9 and collimating slits 52 to transmit selectively XKrays of a particular wavelength. Fig. 10 shows a spectrograph in which an X-ray tube 36 provided with a filter 37 directs a monochromatic beam of primary X-rays on to a specimen 9, generating secondary X-rays of different wavelengths, some of which strike reflecting crystals 38 and 39. X-rays of different wavelengths are reflected at different angles and crystals 38 and 39 therefore selectively reflect those wavelengths which are in turn reflected by crystals 40 and 41 into the counter 2.

Title: Improvements in electron discharge tubes for generating or amplifying electric currents
IPC: H03B7/04
Filed: 1925-02-06
Abstract: 228,935. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Feb. 9, 1924, [Convention date]. Thermionic generators and amplifiers.-Relates to electron discharge tubes in which a perforated " toregrid, " carrying approximately the same voltage as the anode, is utilized in combination with the ordinary control grid to secure a negative-resistance characteristic, there being no back coupling between the anode and grid circuits. The device may be used as an amplifier or as a generator of high-frequency oscillations. An adjustable non-inductive resistance 10, preferably equal to the absolute value of the negative resistance of the system, is arranged to be common to the two current circuits formed between the cathode 2 and the foregrid 3, and the cathode 2 and control grid 4 respectively. The telephones 12 are inserted in the circuit of the anode 5. Fig. 2 shows the variation of the foregrid current ig<1>, and the anode current ia, as a function of the control grid voltage vg for a constant voltage on the anode 5 and foregrid 3, showing a negative resistance characteristic between the points C and D. This may be utilized say between the points P, Q. Fig. 1. When used for two-frequency amplification, the input is offered across a transformer 9, 8. An initial decrease in the voltage of the control grid 4 diverts electrons from the anode 5 to the foregrid 3. The growth of current in that grid circuit continues owing to the voltage fall across the resistance 10 until it absorbs practically the whole of the electron emission from the cathode. The corresponding fall in anode current is indicated in the phones 12.

Filed: 1955-02-07
Abstract: 765,002. Disc brakes. LAMBERT BRAKE CORPORATION. Feb. 7, 1955 [May 17, 1954], No. 3593/55. Class 103 (1). In a disc brake of the kind wherein a friction disc 18 and a backing plate 19 are spread apart so as to engage friction pads 18<SP>1</SP> and 191 with the inner radial faces of a rotatable drum member 8 and such engagement is intensified by the action of camming balls 21 in recesses 22. Automatic adjuster means comprising a screw member 30 is carried by the anchor member 14 and acts to limit the clearance between the pads and drum when the brake is released. Rotation of the disc 18 by the drum when turning in one direction causes the screw 30 to turn in its mounting but such movement is prevented for the other direction of drum rotation by a spring pawl 33 engaging notches or teeth 32 on the head 31 of the screw, the screw then acting to transmit torque to the anchor member 16. Rotation of the backing plate 19 in one direction is prevented by the engagement of lugs 25 thereon with lugs 16 on the anchor plate so that there is no noise resulting from the abutment of surfaces after play has been taken up as in similar earlier brakes. Actuation of the brake is by means of an annular fluid pressure piston and cylinder 36, 37.
