IPC: B66B3/02
Filed: 1924-11-14
Abstract: 237,476. Brown, C. O., and Bacon, A. V. Nov. 14, 1924. Tell-tale apparatus.-In a lift system indicators are provided in each lift which show at all times the positions of each of the other lifts and also the directions in which they are travelling. Each indicator has a dial 8, Fig. 2, marked with the numbers of the floors and an aperture 9 behind which appears the word " up " or " down." A spur wheel 13, Fig. 3, on the spindle 11 of the pointer 12 is rotated in opposite directions by pawls 17 pivoted to the armature 16 of pairs of electromagnets 14, 15. Stops 20, 22 ensure the correct movement of the pawls. The words " up" and " down " are marked on a light pivoted plate 23 which is rocked bv tappets 26 attached to the armatures 16. The indicator is actuated bv a contact arm 30 on the other lift which slides on a vertical guide bar 32 fitted with contact blocks 33. A wire 34 connects the blocks 32 to a terminal 35 connected with the windings of both sets of electromagnets. The return wires 36, 38 of the electromagnets lead through open switches 37, 39 to the same pole of the battery 31. The other pole is connected bv a wire 30<a> to the arm 30. The switches 37, 39 are closed alternatively by the reversing bar 40 of the lift motor.

Title: A selector ring for photographic apparatus
IPC: G03B9/08
Filed: 1962-07-17
Abstract: 998,197. Photographic apparatus. CARLZEISS-STIFTUNG, [trading as CARL-ZEISS] and COMPUR-WERK G.m.b.H., [trading together as COMPUR-WERK G.m.b.H.]. July 17,1962 [July 28, 1961; Aug. 3, 1961], No. 27470/62. Heading G2A. Photographic apparatus comprises a metal housing, a bearing ring formed of a plastics material and rotatably mounted on said housing, and a metal setting disc provided with control means effecting setting alterations, the bearing ring and the control disc being coupled for common rotation and the bearing ring having an expansion-compensating gap and being in engagement with a circular metal holder on the housing for preserving the required diameter and circular shape. As shown in Fig. 1, a bearing ring 10 of polystyrene or polyvinylacetal rotatably mounted about the aluminium objective casing 1 is split at 9 and is formed with a recess 14 in which a lug 11 on a metal setting disc 8 bearing cam slots 3 controlling shutter speeds, while an aluminium girth band 12 is secured by screws 16 to the ring 10 at a point diametrically opposite the gap 9. The girth band which may carry a shutter speed scale may be knurled or have a continuous easy grip ring bearing such a scale secured to it or a finger piece may be attached to cover the opening in the girth band. Instead of a straight sided split, the gap 9 may be of a circumferential tongue and groove form, giving greater axial rigidity to the ring. In Fig. 9 which concerns a diaphragm setting ring, the plastic bearing ring 10a has a compression spring 36 tending to open the gap 9a so that the ring is sprung into a fixed channel shaped mount 30 screwed to the objective casing 1 and bears against the inner periphery of the mount leaving a space between the ring and the casing 1. In alternative arrangements the ring gap is closed by a tension spring or a spring surrounding the ring so that it is urged into engagement with the casing 1 and leaves a space between itself and the mount 30. The bearing ring may have formed in it cams which control the diaphragm adjustment for flashlight exposures.

Filed: 1958-08-27
Abstract: 869,376. Portable gramophones. PYE Ltd. Aug. 18, 1959 [Aug. 27, 1958], No. 27498/58. Class 40 (2). A portable transistorized record-player for disc records comprises a case having an edgewise slit 2 for insertion of a record, a pair of grip - ping members 8, 15 for supporting and positioning a record for rotation about its central axis and an actuating lever 28, engageable by - the record on a step 31 to start the mechanism when the record is pressed fully downwards. A latch mechanism holds the lever 28 in the fully depressed position, whereupon the member 15, in clamping the record raises it slightly to clear the step 31. A motor 6 whose shaft 6a drives the member 8 via the friction wheel 9 is switched on and a further linkage (Fig. 1, not shown) swings the pick-up into engagement with the record. After play, pressure on a member 21 reverses these processes and releases the latch so that the record is sufficiently ejected by the step 31 to be removed. When the player includes a radio or is used in conjunction with a radio, further switches replace the radio signal to the audio stages of the radio by the pick-up signal when a record is inserted.

Filed: 1929-09-10
Abstract: 319,010. Ward Leonard Electric Co., (Assignees of Kouyoumjan, H. K.). Sept. 15, 1928, [Convention date]. Transformers.-In a transformer for supplying a load circuit 13 with current at a voltage that remains substantially constant or varies in a predetermined manner when the voltage of the supply source 8 increases or decreases, the secondary winding 11 embraces two core limbs traversed by the main flux one of which carries a winding 9 that generates a flux in opposition to the main flux while the other limb carries a winding 10 that generates a flux in the same direction as the main flux. In one arrangement, Fig. 1, the main flux is generated by a winding 6 arranged on a separate limb and connected to the supply source 8 in parallel with the windings 9, 10 which may be connected either in series with each other as shown or in parallel with each other. In an alternative arrangement, the winding 6 is connected in series with the windings 9, 10. In another arrangement, Fig. 6, the main flux is generated by a winding 6<1> embracing the limbs carrying the windings 9, 10, the load circuit 13<1> being connected across a part of the winding 6<1> as in an auto-transformer. The winding 6<1> may be connected either in parallel with the windings 9, 10 as shown, or in series therewith. In each case, a current-limiting resistance R is placed in series with the winding 6<1>. Tap connections may be provided on the secondary windings for supplying load circuits requiring different voltages. Two or more secondary windings may be provided on the core for feeding separate load circuits such as the anode and filament circuits of thermionic valves, a rectifier being associated with the anode supply winding. An exciting winding energized from the rectified current may be provided on one of the core limbs. Specification 255,688 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises a further arrangement, Fig. 5, (Cancelled), in which the coil is divided into parts 1<a>, 2a, the part 2a being of smaller cross-section and having an air gap 2<c>. Windings 6<a>, 9<a> connected in series and generating fluxes in opposite directions are provided one on each core part, the secondary winding 11<1> supplying the load circuit 13<1> being arranged to embrace both core parts.

Abstract: 535,481. Mounting grinding wheels. LIDKOPINGS MEKINSKA VERKSTADS AKTIEBOLAG. Oct. 9, 1939, No. 27546. Convention date, Oct. 31, 1938. [Class 60] A grinding wheel 1 is mounted to a hub 5 coupled to the spindle 8 to rotate therewith and having anti-friction bearings 20, 21 to permit the hub to slide freely on the spindle. The wheel is supported on a sleeve 2 which is itself secured to the hub between a flange 6 and nut 7. The spindle 8 which may be motor-driven is carried in self-aligning doublerow ball bearings 10, 11 protected by labyrinth or other packings 12-15 the members 13 and 14 having annular sealing flanges 23, 24. The sliding bearings consist of bushings 16, 17 in the hub and similar bushings 18, 19 on the spindle, separated by balls arranged longitudinally and peripherally in cylindrical tubular retainers 21. For moving the wheel axially a slidable rod 25 is connected to the hub by a key 26 and is also connected through thrust bearings 28 to a block 29 which is movable axially in a housing 30 by means of a hand wheel 34 screwing over an extension 31 of the block. In one application a torsion spring member 37 is finished by cantreless grinding between a regulating wheel 36 and an axially movable wheel 1 mounted as above described. The ends of the wheel are shaped in accordance with the fillets 41 of the work and by axial movement of the wheel both fillets may be ground until a satisfactory surface thereon is obtained. In a modification the spindle and the bore of the hub may be polygonal in crosssection, balls or rollers being placed between the hub and spindle to reduce friction, the key being thus relieved from the friction of transmitting rotation.
