Title: Elevator signaling devices
IPC: B66B1/18
Filed: 1973-03-13
Abstract: 1429674 Automatic control of elevators HITACHI Ltd 13 March 1973 [15 March 1972 21 April 1972 (2) 31 May 1972] 11889/73 Heading B8L  In a multi-car elevator system, passengers are given advance notification, by means of lamps, or audio signals, of the particular car to which a hall call has been allocated, independently of the approach of the car to the floor, an indication being given when the car is about to arrive. In the logic circuit of Fig. 6a (not shown), in dependence upon the positions, and hall call loadings of each car compared with the average hall call loading, a registered hall call is allocated to one of the cars, for example car A, an AND gate, e.g. (A9UA4, Fig. 6a) for a ninth floor up hall call being enabled, in turn operating, via thyristor (R9UA), Fig. 9 (not shown), relay (R y 9UA) energizing lamp (S9UA), Fig. 10 (not shown), to give the notification. The relays R y 2DA-R y 9UA also enable lift deceleration to take place. By means of an alternative logic circuit, Fig. 6b (not shown), the precise allocation is not made upon registration of the hall call, the notification being made only when the particular car to be allocated is established. The notification may be given for each direction for each floor (Fig. 10), or a single indicator for each floor may be used for both directions (Fig. 12). By provision of a flicker relay (FA), Fig. 11 (not shown), or a resistor (not shown), each notification lamp may flicker, or be dimmed, as the allocated car approaches the floor. At the initiation of car deceleration to stop at the floor, indication is given by arrival forecaster (HL9UA), Fig. 13 (not shown). The audio indicator means, in the form of a tape recorder giving a verbal message, or chimes, or bells, Figs. 17, 18, 19 (not shown), is provided for each floor, for each car, or group of adjacent cars. The modification of Fig. 16 (not shown), ensures that, should calls from a landing in both directions be allocated to a single car, notification is given only for that direction in which the car is currently moving. Disposition of indicators. Figs. 14a-14g (not shown).-The notification lamps, or sound sources, and arrival forecasters may be located adjacent each car entry (Figs. 14a-14d, 14g), the former delivering a message (Fig. 14d), the notification may be projected on to the lift door, (Fig. 14e), or indications, with car identification, may be given centrally (Fig. 14f). Circuits for determining the physical position (d a , d b , d c ) and hall call load for each car (CA, CB, CC) as well as hall call load averaging circuitry are disclosed. Figs. 1-3 (not shown), there being a comparator, Fig. 5 (not shown), for advancing the effective position of each car by 0, 1 or 2 floors, in dependence upon the values of (d a , db, d c ; CA, CB, CC) and the average hall call load signal (C). Means are provided to exclude a full, reserved, or out of service car from allocation.

Abstract: 398,455. Mercury switches. HARTMANN, J. F. G. P., 10, Kastelsvej, Copenhagen. April 24, 1933, No. 11985. Convention date, May 21, 1932. [Class 38 (v).] In an electric commutator or like device having conducting segments moving past stationary brushes formed by mercury or like jets, one or more insulated knives are arranged to move round with the segments and to cut the jet in such a manner that the arc formed when a segment leaves a jet occurs mainly between portions of the jet. In the form shown in Fig. 1, two electrically connected jets J<1>, J<2> engage the rotating segments E<1> .. E<6> between the adjacent ends of which are arranged the knives W<1> .. W<6>. As a knife leaves a jet, two arcs spring from the rear corners of the knife to the portions of jet cut, but these arcs almost immediately coalesce to form a single arc between the two portions of jet. Fig. 3 shows a modification in which two jets J1, J1<SP>1>, moving perpendicularly to the paper engage the segments E1, E2, and a knife W moving with the segments cuts the jet J1 but not the jet J1<SP>1>. In all cases the knife must be suitably inclined to the jet so that both portions of the mercury cut remain in contact with the blade during the cutting period.

Title: Photographic cameras and film for use therewith
IPC: G03D9/02
Filed: 1971-04-29
Abstract: 1351971 Cameras and film units therefor EASTMAN KODAK CO 29 April 1971 [1 May 1970 9 Sept 1970 2 Oct 1970 (4)] 12185/71 Headings G2A and G2X A film unit comprises a photo-sensitive sheet 11 and a second sheet 13 secured together as an integral unit 5 and strippably mounted on a supporting web 23 which also has permanently fixed to it a rupturable pod 7 of processing fluid at one end and a trap 19 for collecting excess fluid at the other end, the integral unit being of a rigidity such that flexing of the carrier member causes peeling separation from the integral unit. Several such units may be assembled along one continuous web, and assembled in superposed relationship in a single cartridge Fig. 2. The leading edge of web 23 has an adhesive tab by which it can be connected to a spool 33. Thus as the spool is wound, the pod 7 passes between pressure rollers 63, 65 and is ruptured thereby, the processing fluid being spread between sheets 11 and 13. The carrier is wound on to spool 33, and so is peeled away from the more rigid unit 5, which passes out of the cartridge exit slot 45 and straight on through the camera exit slot 71. Thus the finished photograph passes out of the camera while the waste material remains wound on spool 33. Inanalternative arrangement, Figs. (not shown) 44-49, the pack of film units has a dark slide cover which is initially pulled out of the camera in order to make the first exposure, and brings with it the leading end of the carrier sheet, through a first exit channel from the camera. The path to this first exit diverges from the direction of movement of the unit towards the pressure-applying rollers. Thus the more rigid film unit strips away from the carrier sheet, and continues in its original direction of movement, and so passes out of the camera through a second exit channel. The film unit may be transported by a metering pawl entering a film perforation, the pawl being driven by spring means or electrical means, or instead of a perforation the edge of the film may have a conductive strip forming part of the energizing circuit, as in Figs. (not shown) 13 and 14. Instead of the units being attached to a continuous web support, each unit may have its own support, and the unit may be stripped from the support manually Fig. 18 (not shown). When attached to a continuous support, the units may be folded into a stacked configuration for insertion into a camera.

Loud - speakers; diaphragms.-Relates to sound reproducing instruments of the kind claimed in the parent Specification in which the diaphragm comprises a sheet of stiff material folded along a straight line and then unfolded so that the two parts make an angle with each other along the line of fold, the sheet being then deformed so as to present a conical surface. According to the present invention the diaphragm is made asymmetrical in shape, the part 6<1> 'responsive to low frequencies having a larger surface than the part 6<11> responsive to high frequencies. The diaphragm is vibrated by motor units 3, 4 having different characteristics arranged at each end of the fold, the operation depending on the toggle principle. The angle of the toggle at the apex of the diaphragm may be varied by displacing by a nut 8 one of the driving points of the diaphragm. The diaphragm may be built up of superposed sheets each having a smaller area than the one beneath it, so that the composite diaphragm is thinner at its edges than elsewhere. Strengthening ribs 5 may be formed along radii at right angles to the line of fold.

Abstract: 476,285. Explosives. HERCULES POWDER CO. May 3, 1937, No. 12614. Convention date, May 11, 1936. [Class 9 (ii)] Crystals of ammonium nitrate are coated with a metal nitrate in order to increase their sensitiveness to detonation. According to a preferred method, a solution of a metal nitrate is added to the ammonium nitrate crystals and the mixture dried. The coating solution may also contain ammonium nitrate and is preferably almost saturated with the metal nitrate. Alternatively, ammonium nitrate crystals are treated while wet with the metal nitrate in dry condition. According to one example, a solution is prepared by dissolving 132 parts by weight of ammonium nitrate and 50 parts by weight of sodium nitrate in 66 parts by weight of water at about 27‹ C., this solution being saturated with respect to ammonium nitrate and almost saturated with sodium nitrate. This solution is then applied at 27‹ C. to 950 parts by weight of dry granular ammonium nitrate of such particle size that over 95 per cent will pass a 40 mesh screen, about 30 per cent will pass a 100 mesh screen and less than 10 per cent will pass a 200 mesh screen. After thorough mixing, the crystals are dried by passing through the mass a current of dry air at about 50 to 60‹ C. with continuous stirring. If desired, the drying may be effected merely by heating the coated crystals and, in this case, the coating solution is preferably heated before applying same to the crystals. The sodium nitrate may be replaced by the nitrate of potassium, copper, lead, zinc, cadmium, nickel, iron, calcium or magnesium. Carbonaceous and/or organic sensitizing ingredients may be dispersed or dissolved in the coating solution. Thus, coal, charcoal, corn meal, flour or wood pulp may be used as the carbonaceous ingredient whilst dinitrotoluene oil, solid dinitrotoluene, trinitrotoluene, dinitronaphthalene and other liquid and solid nitrocompounds may be used as the sensitizing- agent.
