Title: Improvements in or relating to controlling the feed of grinding tools
IPC: B24B7/07
Filed: 1971-04-19
Abstract: 1285425 Grinding GUSTAV GOCKEL MASCHINENFABRIK GmbH 19 April 1971 [9 April 1970] 23228/71 Heading B3D A method of effecting the feed of a grinding tool 6 of a surface grinding machine during grinding of an elongate workpiece 12 comprises feeding the tool into the workpiece in steps spread along the length of the workpiece during relative movement between the tool and workpiece in the direction of the length of the workpiece. The workpiece, such as an industrial cutter, is fixed to a bed 2 along which a carriage 4 is reciprocated under the control of a non- contact magnetic switch 14 reacting with adjustable permanent magnets 16. The grinding tool 6, which may be a segmental grinding head, is rotated by a motor 8 and is vertically adjustable along guides 10 by a lead screw 20 and nut 18. A continuously running motor 22 is connectable to the screw by an electromagnetic clutch 24 controlled by a device 26 having a pair of timing relays which respectively control the time the clutch is engaged and disengaged, i.e. the depth of feed of the grinding wheel and the interval between the feeding movements.

Title: Improvements relating to copying drawings, printed matter and the like by photography
IPC: G03C5/50
Filed: 1925-09-17
Abstract: 249,467. Akt.-Ges. fiir Anilia-Fabrikation. March 21, 1925. [Convention date]. Treatment after development. -Consists in a process of copying originals, such as drawings or printed matter, wherein (1) a negative is made from the original in a silver emulsion, and is treated in a bath which produces a deposition, on the silver-containing parts, of such a character that it prevents the penetration at those parts of a hardening-agent contained in the bath, while the unexposed parts of the negative are penetrated and tanned thereby; and (2) the negative is treated mechanically or chemically to convert it into a positive. In an example, immersion of the negative for 20 seconds in a bath containing ferric chloride, potassium ferricyanide, and potassium bromide is specified. A lightlyadherent layer of Berlin blue is formed at the silver-containing parts which prevents penetration of the hardening-agent at those parts. On spraying with water, the Berlin blue is transferred to the unprotected parts of the layer, wherein it is mordanted by the ferric chloride. The bath also bleaches the silver image, so that a blue positive on a white ground results. If the copy obtained is weak, it may be strengthened by immersion in a bath of potassium ferrocyanide. The image may be further strengthened by toning, or by the inclusion of mordant dyestuffs in the hardening bath. The hardened parts may be washed away with hot water, and the residual parts coloured with dyestuffs. Lateral inversion may be avoided by using a film on a transparent support; or, if an opaque support is used, by employing an inverting prism when copying, or by finally rendering the support transparent by the application of oil. Formaldehyde or quinone may be added to the hardening-bath to increase the tanning action, and also salts of other metals such as uranium.

Filed: 1925-09-21
Abstract: 262,872. Western Electric Co., Ltd., and Deloraine, E. M. Sept. 21, 1925. Thermionic modulating systems.- A high-frequency wave is modulated by variably absorbing high frequency power from the output of the amplifier or oscillator or both and impressing the absorbed power on the plate circuit so as to augment modulation. The Figure shows an oscillator 2 of the Colpitts' type and an amplifier 3 energizing an antenna system 15, 7. Energy is absorbed from the load circuit through a coupling 4 to a rectifying device 5 controlled at audio frequency by a microphone 9 and a transformer G is so connected as to apply the energy to the plate circuit of the amplifier 3 to augment the modulation. Alternatively the absorbed energy may be stored in a condenser of large capacity during one half-cycle of the modulating wave and used to carry on the modulation on the plate modulation principle in the next half-cycle. Specifications 133,366 and 168,056 are referred to.

Title: Improvements in transmission of motion from closed space

Abstract: 913,926. Linkwork. YARNALL-WARING CO. July 7, 1960 [Sept. 24, 1959], No. 23826/60. Class 80 (3). [Also in Groups XVIII and XXXVII] In mechanism for converting the linear motion of a float 50, Fig. 9, or other device in a sealed chamber 35<SP>3</SP> into angular motion of a switch element 84 or other device outside the chamber, e.g. in a liquid level gauge, the element 84 is mounted on the outer end of a spring wire 31 extending into a resilient tube 30 which is sealed in the chamber wall, the tube 30 being curved in part of a helix and having the float 50 attached to its closed free end 32 so that linear movement of the float deflects the tube 30 in a direction parallel to the axis of the helix. The wire 31 may be formed to the same curvature as the tube, in which case progressive deflection of the tube causes a progressive relative angular movement between the outer ends of the tube and wire, or may be oppositely curved to give a snap action. Alternatively the wire and tube may be formed as in Fig. 18 so that their natural curvatures are partly similar and partly opposite to give a snap action following a progressive movement. As shown, the element 84 carries switch contacts co-operating, with snap-action, with fixed contact strips, and is clamped on an insulating block on the wire 31. A pigtail 87 connects the element to a fixed terminal. A fixed curved tube 73 provides upper and lower stops for the tube 30. In a modification dispensing with the tube 73, upper and lower stop-rods extend from the chamber wall, and the tube 30 has at its end a reverse curve on which the float 50 is suspended. In a further modification the element 84 is replaced by an arm operating the buttons of separate switches and is mounted on a wire extending fully into a resilient tube formed in a complete helix turn, the inner ends of the wire and tube being secured together. The resilient tube may contain more than one spring wire actuating separate devices.

Indicators, trump and like; marking-apparatus. -The declaration indicator for card games according to the parent Specification is modified by the provision of a manually operated device adapted to engage and lock the freely mounted indicator during the adjustment of the other indicator. In addition, markers in the form of radial arms having reading apertures are independently adjustable about the axis of the operating member to indicate the state of the game. The indicator comprises two dished discs 15, 16 mounted on a spindle 1 and rotatable by a knob 11. The disc 16 is inscribed with signs indicative of the nature of the declaration and is rotatable with the spindle 1, while the disc 15 indicates the number of tricks bid and is freely mounted on the spindle but pressed into engagement with the disc 16 by a spring-washer 20. The discs are viewed through an aperture in a casing 6. Counterclockwise rotation of the disc 15 is prevented by a spring-pawl 22 cooperating with ratchet-teeth 21 on the periphery of the disc. In addition, rotation of the disc 15 in a clockwise direction may be prevented by depression of a knob 26 connected to a spring- retracted detent 24. The state of the games and rubber is indicated by two radial arms 30, 31, both of which are rotatable about a pivot 32 coaxial with the spindle 1 and have two longitudinal positions. The score in the first game for either side is indicated by rotating the arm corresponding to that side until the appropriate numeral is visible through an aperture 33 in the outer end thereof. Before marking the score in the second game for that side, the arm is returned to zero position and moved outwardly, the score being then indicated through an inner aperture 35. Spring arms 53, 54 cooperate with the radial arms 30, 31 and with projections 48 on the base plate to position the former.
