Title: Safety device for suspended loads
IPC: B66D1/54
Filed: 1976-09-16
Abstract: 1513075 Catch gear GRANGES FAHRZEUGTECHNIK GmbH 16 Sept 1976 [24 Sept 1975] 38393/76 Heading B8L A safety device for a suspended load 5 comprises a carrier band 2 which extends from a spring-loaded drum 12 through a slot 33 in a braking spindle 31 into a U-shaped loop 22 from which a connecting element 25 for the load suspends. The braking spindle is biased by weights 36 or magnetically to a position with the slot 33 aligned for free travel of the carrier band 2. The spindle carries drums 34, 35 for actuating bands 42, 43 which are connected to the carrier band 2 by a yoke 41. If the suspending ropes 16, 17 fail the falling load extends the carrier band 2 rapidly which causes the drum 12 to lock and the carrier band extension is stopped. The actuating bands 42, 43 thus extend and rotate the spindle 31 to lock the carrier band 2.

Abstract: 360,727. Valve accessories and components. FORENEDE JERNSTOBERIER AKTIESELSKAB, 5, Gyldenlovesgade, Copenhagen. Dec. 22, 1930, No. 38513. Convention date, Oct. 13. Grant of Patent opposed. [Class 135.] Closure members, lift ; locking.-A valve in the outlet nozzle of a ventilating duct comprises a cone, pyramid, or the like slidably mounted within the nozzle, contours and proportions being such that the air passage between the inner surface of the nozzle wall and the cone &c. is approximately of uniform cross section over the greater part of its length throughout a considerable range of adjustment from the fully open position. The nozzle comprises a stream-lined inner wall 5 and a spherical outer portion 4 universally mounted in the wall of an air duct. A spider 6 in the nozzle carries a body 21 within which is slidably mounted a stem 20 carrying a handle in the form of a cap 22 and a cone valve member 10. The air supply issues from the duct through the space between the member 10 and the wall 5 and is controlled by sliding the stem 20 in its mounting. In a limiting position the member 10 contacts with the wall 5 at the inlet end of the nozzle and closes the air passage. Within the body 21 is a helical spring 25 bearing at its upper end against a cover 27 screwed into the body and at its lower end against a loose ring 28 resting on balls 24, which are thus pressed between the stem 20 and a wedge-shaped recess 23 in the body 21 ensuring sufficient friction to hold the valve in position against the pressure of the air. In a modification the valve member contacts with the wall 5 at the outlet end of the nozzle and the stem is frictionally held in a slit resilient bush. In a further modification, Fig. 9, the nozzle is shown rigidly mounted in the duct but may be universally mounted and the body 21 and stem 20 are carried by a baffle member 31 mounted by means of supports 32 immediately in front of the nozzle and serving to deflect the issuing air.

Abstract: 1367360 Electron beam focusing apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Aug 1971 [21 Aug 1970] 38752/71 Heading H1D Electron-optical apparatus (e.g. in an electron microscope, scanning microanalyser or beam machining apparatus) for focusing an image forming electron beam includes magnetic lens means for providing a rotationally-symmetrical magnetic field about the beam axis, an auxiliary electron source (7) located away from the axis so that focusing is not disturbed, the auxiliary source providing an auxiliary non-image forming focused beam directed to one side of the first beam and crossing the axis at not greater than 30 degrees so as to describe a generally helical path about the main beam to provide a corresponding space charge compensating for spherical aberration effects. The space charge may be formed by secondary electrons by gas ionization, pressures being 10<SP>-4</SP> to 10<SP>-10</SP> torr. Alternatively, the beam may itself remain in the region sufficiently long that a space charge is built up, or both effects may operate. Fig. 1 (not shown) includes coil (2), ferromagnetic shield (4), and air gap (5), which may be replaced by a permanent magnet or e.m. pole shoes, and source (7) with magnetic lens (13) mounted in anode (11). Non-ferromagnetic sleeve (15) at positive potential repels positive ions, producing a negative space charge. Variation of sleeve (15) potential controls the injection direction. Fig. 2 (not shown) includes anode (11), control electrode (10), deformable rings (16) and (17) enabling alignment of the gun after mounting by adjustment screws (not shown). The electron microscope of Fig. 3, includes condenser lens 22, main lens 2, projector lens 23 and target screen 24. Permanent magnet lenses may be used.

Abstract: 1,124,105. Electric toy vehicles. I. TSUNODA. 10 Sept., 1965 [10 Sept., 1964], No. 38829/65. Heading A6S. An electrically driven toy vehicle has an inertial disc 1 on a screwed motor shaft 5 to effect operation of a changeover switch 26 to reverse the device, and means 53 to interrupt the drive upon said drive reversal. Fig. 2 shows a plan view of a vehicle, wherein the changeover switch 26 is held in the position shown during forward drive. When the vehicle slows, due to an obstruction, or to resistance introduced into the circle by sound-actuated means, illustrated in Fig. 6 (not shown), the disc 1 runs along the screwed shaft 5 and moves the forked end of a bar 22 to the right, as viewed in Fig. 2, to move the switch 26 to its other extreme position whereby the current direction is reversed to drive the motor shaft and gear 10 in opposite direction. The road wheel 57 cannot reverse owing to a pair of clutch members 54, 54a but the other wheel (not shown) on the opposite end of shaft 16 does reverse a small amount until current is interrupted by a switch 53 so that the vehicle turns a little as well as reversing a little. A quadrant gear 65 driven by shaft 16 may also turn the steering in the same direction by a rod 64. Alternatively the rod 64 may be used to raise a bulldozer blade. Immediately upon the vehicle stopping the inertial wheel returns to its initial position to re-establish forward drive.

A frequency demodulator of the ratio detector type comprising two resonant circuits 1 and 2 and tertiary winding 3, a pair of diodes 4 and 5 being connected in series across one of the tuned circuits, is characterized by the provision of a resistance 9 in the path of the A.C. and the recovered modulation between the winding 3 and the output capacitor 6. Amplitude limitation then occurs because of amplitude-dependent division of the voltage from winding 3 between the diodes and the resistance 9: consequently the circuit 2 can be of lower resistance (fewer turns on the secondary winding) and the diodes 4 and 5 may be normal diodes instead of special low-capacity diodes. In modifications the resistance 9 is shunted by a capacitor (10, Fig. 3, not shown); a capacitor (11, Fig. 4, not shown) connects the junction of the diodes to the winding 3; the diodes are connected across the primary tuned circuit (Fig. 5, not shown); the winding 3 is omitted and the centre tap of the secondary winding is connected to one end or the centre of the primary winding (Fig. 6, not shown); the junction of resistance 9 and capacitor 6 is earthed and the output taken from the junction of capacitor 6 with winding 3 (Fig. 7, not shown); in a similar arrangement (Fig. 8, not shown), the resistance 9 and capacitor 6 are connected to opposite ends of the winding 3; the resistance 9 may be connected between one end of winding 3 and the centre tap of the secondary winding (Fig. 9, not shown), or between the other end of the winding 3 and capacitor 6, the other side of which is earthed (Fig. 10, not shown).
