Title: Driving mechanism for lift doors
IPC: B66B13/12
Filed: 1981-03-11
Abstract: In a driving mechanism for operating lift car doors 106, the doors are coupled to a horizontal loop of rob 3 part of which is wound around a drum 1. The drum 1 has a central axis 4 on which it can rotate and move horizontally in a slot (104) (Fig. 1, not shown), and a peripheral axis on which is can rotate and move vertically in a slot (102) (Fig. 1, not shown). These constraints cause the rope coming off the drum to move with a kind of cycloidal motion providing a region of effectively zero rope movement toward the ends of the drum rotation. Door movement is made smoother by this motion. An electric motor 14 operates through belt and pulley gearing to drive a pulley wheel 7 on which is eccentrically-mounted the drum 1. <IMAGE>

Patent GB-814171-A (GB)
Abstract: 814,171. Zeroizing-mechanism; transfermechanism; counting-apparatus. GROSS, H., and GROSS, S. Oct. 27, 1955 [Nov. 24, 1954], No. 34050/54. Class 106 (1). A totalizer unit of a key-set and -operated cash register carries a re-setting lever which, when actuated, drives the totalizer wheels to their zero positions and rocks a member into engagement with the tens transfer levers to prevent operation thereof. The totalizer unit is similar to that described in Specification 618,357 and is rockable about a shaft 14, for engagement with actuating segments, by the action of a cam on a stud 15. Transfer mechanism.-At transfer, a tooth 21a, Figs. 5 and 7, rocks a trip pawl 33, 34 clockwise to disengage it from a bar 35 and permit clockwise rocking of a corresponding transfer lever 25 on which it is pivoted. The operated transfer levers are returned seriatim by the action of cams (not shown) on rollers 62. As each transfer lever is restored, a pawl 28 carried thereby advances by one step a ratchet wheel 22 fast with the totalizer wheel of the next higher order. Zeroizing mechanism.-On depression of the re-setting lever 52, Fig. 3, a cam slot 54 therein acts on a stud 65 in a gear 18 to rotate the latter, which meshes with a pinion 17 on the shaft 16, of the totalizer wheels 20, Fig. 5. The shaft 16 is formed with a groove 66 so that on rotation, it picks up pawls 67 pivoted in the totalizer wheels and advances the wheels to their zero positions. The cam slot 54 is so shaped that the speed of rotation of the shaft 16 is high initially but is gradually reduced as the movement is completed so as to arrest the totalizer wheels smoothly. The teeth of the totalizer pinions 23 have semi-cylindrical outer ends for co-operation with the rounded ends of detent pawls 41. A second cam slot 53 in the re-setting lever 52 rocks a plate 58 which engages cam-shaped ends 61 of the transfer levers 25 to prevent their release as the trip pawls 33, 34 are rocked by the transfer teeth 21a. Near the end of the operative stroke of the re-setting lever, the plate 58 is rocked back slightly to lower the transfer levers to permit the passage of the transfer teeth 21a. To ensure a full-stroke of the re-setting lever 52, a notched disc 68, Fig. 2, co-operates with a pawl 73. The disc 68 also co-operates with a fixed stud 72 to prevent simultaneous zeroizing and adding operations, adding, which involves the rocking of the totalizer unit, normally being allowed by the alignment of a slot 71 in the disc with the stud. Totalizer wheel construction.-Each totalizer wheel 20, Figs. 5 and 7, is recessed on one side to receive its zeroizing pawl 67 and on the other side to locate the transfer tooth 21a which is formed on a disc 21. The latter and the ratchet wheel 22 engaged by the transfer pawl are splined internally for mounting on a splined sleeve 81 integral with the pinion 23. The sleeve 81 fits over a hub 80 extending from the wheel 20, the end of which is expanded to secure the parts together.

Title: Bidirectional, interactive fire detection system
IPC: G08B25/04
Filed: 1982-03-05
Abstract: A communication system useful for fire detection which transfers data/ commands bidirectionally between a controller and connected transponders on a real time, interactive basis, makes possible accurate data recovery, whether a transponder has its output shorted, or although multiple transponders are replying at the same time. The system makes possible the remote determination and constant monitoring of transducer sensitivity, at the controller. The sensitivity can be adjusted remotely at the controller, and different transducers can have different thresholds simultaneously. These thresholds (limits) can be changed collectively or individually to different settings manually or automatically at the controller. The system transmits reference data for supervision of system accuracy. Compensation for long-term changes is provided for both transponders and transducers. <IMAGE>
