Title: Electron beam apparatus for recording image elements
IPC: H01J37/302
Filed: 1969-05-23
Abstract: 1,269,156. Electron beam irradiation apparatus. NETHERLANDS CENTRAL ORGANISATION FOR APPLIED SCIENTIFIC RESEARCH. 23 May, 1969 [27 May, 1968], No. 26485/69. Heading HID. In an electron beam recording apparatus the beam is operated at constant intensity and is modulated in area. In Fig. 5 electrons from a slit source B pass through a biprism comprising . a tungsten wire 16 surrounded by a coaxial cylinder (15, Fig. 4, not shown) provided with diametrically opposed apertures for the passage of the beam; when energized the biprism makes the beam appear to emanate from two virtual sources B1 and B2. The beam then passes through two quadrupole lenses A 1 and A2, a diaphragm D1 and a second diaphragm D2 to the record cylinder 20 which rotates about its axis and also moves along its axis. The resulting image is two lines C1 and C2 about 100 microns long and a few microns wide, the separation d depending on the voltage applied to the biprism. After exposure the cylinder 20 may be etched to form a printing cylinder. The quadrupole lenses preferably each comprise two pairs of oppositely energized coils (Fig. 2, not shown) and control the magnification along two axes; they are preferably rotatably mounted in a tube along which they are movable axially. Another arrangement, Fig. 6 (not shown), comprises two quadrupole lenses (Al and A2) between which is arranged a biprism, and a central stop which intercepts the beam; when the biprism is energized two beams pass the edges of the stop and are combined by a second biprism (G) and a symmetrical lens (H) into a single line image whose length is determined by the modulation. In a modification, Fig. 9 (not shown), the quadrupole lenses are replaced by electostatic lenses each in the form of three discs with slit apertures. In a further arrangement, Fig. 7 (not shown), the beam is shaped by one diaphragm (L) and deflected by the modulation across a second similar diaphragm (O) to vary the area of the beam which is then deflected back to the axis and focused on the cylinder. The diaphragms may be sectors of circles (Figs. 8a and 8b, not shown) or square plates provided with numerous square apertures (Fig. 8c, not shown).

Title: Improvements in and relating to the surface hardening of metal articles
IPC: C21D1/60
Filed: 1934-09-18
Abstract: 446,495. Surface - hardening metal articles. DENNEEN, F. S., 13508, Woodland Avenue, Cleveland, and DUNN, W. C., 3009, Claremont Road, Shaker Heights, both in Ohio, U.S.A. Sept. 18, 1934, No. 26739. Convention date, Sept. 18, 1933. [Class 72] [See also Group XI] In the surface-hardening of metal articles, the surface of the latter are brought into contact with or in close proximity to one or more hollow electrodes provided with holes in the side adjacent the articles, and then after passing a current through the electrodes to heat only the surface of the articles quenching the heated zone practically instantaneously by forcing an aqueous solution of sodium hydroxide or equivalent material having a high thermal conductivity such as calcium chloride or brine through the holes of the electrodes. The article 51, Fig. 1, is surrounded by hollow jaws 40, 41 hinged at the pin 42 and provided with extensions 43, 44 to which are connected conductors 45, 46 leading to a source of highfrequency current. The jaws 40, 41 are provided with nozzles 47, 48 and cooling fluid is supplied thereto by pipes 49, 50. In another form, Fig. 2, the jaws 60, 61 are provided with extensions 62, 63, which are hinged about a pin 64 provided with an insulating bushing and cooling fluid is supplied to the jaws by pipes 65, 66. The valve 67 controlling the supply of fluid is operated by levers 68, 69 so that when the article has been heated, the pulling away of the jaws 60, 61 moves the levers 68, 69, thus cutting off the current and simultaneously opening the valve, the cooling liquid being then forced into the jaws and through the nozzles therein on to the article. The invention may also be applied to the surface hardening of crank-shafts, cam-shafts, pins, drills, brake drums and hollow cylinders. Specification 435,343 is referred to.

Title: Improvements in apparatus for driving clocks, time switches and the like
IPC: G04C1/06
Filed: 1934-09-18
Abstract: 422,776. Clocks. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Sept. 18, 1934, No. 26821. Convention date, Sept. 22, 1933. [Class 139] In clockwork mechanism normally driven by a non self-starting synchronous motor and having an auxiliary movement which takes over the drive when the current supply to the motor fails, the motor is started periodically by a device actuated by the auxiliary movement when the latter is driving the mechanism. The invention is applicable to clocks, time-switches, and to any other apparatus actuated in accordance with time. The rotor 1 normally drives the hands 6 through gearing 3, 4 and a double ratchet 5, and winds up the auxiliary movement 8 through an eccentric 14 and ratchet and pawl gear 13. Stray flux from the motor holds an armature 9 causing a lever 27 rigid with the armature to lock the movement 8. When the current supply fails, the motor stops, and a spring 25 retracts the armature to release the auxiliary movement which now drives the hands through gearing 7 and the ratchet 5. A wheel 17 in the auxiliary train has pins 18 which periodically, for example, every fifteen minutes, raise a lever 21 against the action of a spring 20 and then release it, whereupon a lever 22 imparts a starting impulse to a ratchet wheel 24 on the rotor shaft 23. When the current supply again becomes available, the rotor, started in the manner, will fall into step, and pins 10 on a wheel 11 in the train 3 will actuate a lever arrangement 28 to impart a rotary impulse to a ratchet wheel 12 thereby rocking lever 27 to lock the auxiliary movement.

Filed: 1925-10-27
Abstract: 242,279. British Thomson-Houston Co., Ltd., (Assignees of Maclean, J. B.). Oct. 30, 1924, [Convention date]. Alternating-current commutator machines.-An alternating-current motor having a commutator winding for phase or speed adjustment inductively connected to either one of the primary and secondary windings and conductively connected to the other is started as an induction motor and converted into a synchronous motor by reversal of the relative phase rotation between the regulating winding and the winding to which it is conductively connected. If overloaded when running synchronously, the machine continues to run as a synchronous motor. In the form shown in Fig. 1, the primary winding 1, fed from the line at 2, and regulating commutator winding 4 are mounted on the rotor, the regulating winding being connected through the brushes to the stationary secondary windings 8, 9, 10. After starting up as an induction motor in which the phase rotation in the regulating and secondary windings is coincident, the phase rotation in the regulating winding is reversed by means of a switch 11, whereupon the motor pulls into synchronism with a leading power factor which diminishes as the load increases. If loaded so as to fall out of synchronism, it continues to run as an synchronous motor with a higher powerfactor than an ordinary induction motor. In the form shown in Fig. 2, both ends of the secondary windings 8, 9, 10 are connected by brushes to the regulating winding for speed and power-factor control in known manner during induction motor working and the phase-reversing switch 12 is of two-pole form.
