Title: Apparatus for converting alternating electric current into alternating current of lower frequency
IPC: H02M5/00
Filed: 1933-02-06
Abstract: 401,920. Frequency changing ; phase changing. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI, 91, Rue de l'Enseignement, Brussels, Belgium. Feb. 6, 1933, No. 3605. Convention date, Feb. 4, 1932. [Class 38 (ii).] Means for converting single or polyphase alternating current into single or polyphase alternating current of lower frequency comprises an input transformer having a single secondary winding feeding a mercury are discharge device I, Fig. 4, the anode circuits of which are controlled by grids in such manner that an interrupted unidirectional current of the form shown in Fig. 5 is supplied to the mid-point of a divided primary winding of an output transformer with which is associated means (such as another grid-controlled discharge device II) for diverting successive unidirectional impulses through opposite halves of the winding, such means (grids in the arrangement shown) operating in synchronism with the grid control system of the device I. Thus an alternating current of the form shown in Fig. 3 is produced in the secondary winding associated with the divided primary. A commutator switching device driven synchronously with the grid control system of the discharge device I may replace the discharge device II.

Patent GB-1484500-A (GB)
Title: Elevator control apparatus
IPC: B66B1/20
Filed: 1975-01-28
Abstract: 1484500 Multi-car systems HITACHI Ltd 28 Jan 1975 [30 Jan 1974 15 Feb 1974 25 March 1974] 3710/75 Heading G3N In a multi-car elevator control system, signals representing the number of passengers in each car are generated and each signal is distributed amongst the floors for which cage calls are registered in the corresponding car according to pre-set floor weighting ratios, to provide an estimate, for each such floor, of the expected number of in-cage passengers who will alight at the floor. At each floor served, the expected numbers are updated in the light of any nett change in the number in the car, or changed distribution of registered cage calls. The ratios are set by means of potentiometers, see Fig. 13 (not shown) and means may be provided, comparing the sum of the estimated numbers for all the floors at which a cage call is registered, with the measured total number of in-cage passengers, a normalization arrangement ensuring that the sum remains equal to the measured total number. The potentiometer settings, individual to each floor and direction of travel thereto, may be varied in dependence upon the system traffic demand, total number of cage calls, or time of day. Allotment of hall calls. Each car will provisionally accept hall calls from any floor between its effective position and that of the car ahead of it, the cars being regarded as on a ring. The numbers of passengers awaiting service at each of the landings is detected and distributed according to a predetermined weighting system between up and down directions at each such landing, should hall calls for both directions be registered, otherwise being allocated to the sole registered direction from the landing. On the basis of an initial measurement of the in-cage passenger number, a forecast is made, for each car, of the expected number of in-cage passengers for each forward floor, for each floor, by adding the estimated number waiting for service in its direction of service and subtracting the estimated number of the in-cage passengers destined for the floor. The car will accept the hall call provisionally assigned to it only provided that, according to the forecast, the car would leave the floor with an incage load not exceeding a pre-set value representing the car's capacity. The forecast is progressively updated in the light of actual changes in the car's content. Should a particular hall call be rejected by the car, it is re-assigned to the succeeding car, i.e. that car whose secondary provisional service zone, Fig. 2, currently encompasses the landing. The capacity limit may be set individually for each car. For each car, the effective position is its actual position, advanced by none, one or two floors in dependence upon the distance between the car and the succeeding car and the car call load in comparison with the average for all cars. The forecasting may be carried out in digital form, using a computer.

Title: Improvements in pneumatic dust collecting systems and in apparatus therefor
IPC: F16H29/02
Filed: 1920-02-06
Abstract: 156,998. Wilsmore, J. Feb. 6, 1920. Filtering; dust-collectors. - In apparatus embodying a series of tubular filters of canvas, gauze, metal, &c., the whole volume of dustladen air is directed successively along the interior of one or some of the filters at a high velocity, dislodging the dust adhering to their surfaces and forcing it into a storage chamber below; the air is then passed in the opposite direction into and through the remaining filters, which are closed at their upper ends. As shown in Fig. 2, the filtering-hose 9 are suspended vertically from hoppers 10 connected with the under sides of an inlet chamber and covered by gates or valves 13. Each pair of valves is secured to a transverse shaft 14 provided with dust-proof bearings 15 and having lever balance weights 16 at the ends, which hold the valves steadily either open or closed. Each valve covers two hoppers. The shafts 14 carry rockers 17 having grooved pulleys 18, 43 over and under which passes a wire 44 secured to the ends of the casing. The rockers and valves are operated by wires 20 connected to bars 19 passing through guide openings and resting on cams 22. These cams successively permit a bar to drop and engage a rocker 23 operated intermittently by a pin on a roller chain 24. The rocker 23 rotates the cams 22 by means of a pawl 29 and a ratchet-wheel 42, and is returned to its normal position by a weight 28 when released by the pin. The chain 24 is operated continuously by gearing which may be driven by a propeller placed in the path of the incoming air. The valves are thus opened successively, the wire connection 44 between the rockers 17 causing each valve to close as its successor is opened. The air passes down the filters, of which the valves are open into the dust-collecting chamber 11, which is provided with baffles 30 and a conveyer 31, and up through the remaining filter hose.

Feb. 13, 1933, No. 4317. Convention date, Feb. 23, 1932. [Class 17 (i).] Sole-laying.-Relates to machines for roughing the overlasted margins of uppers prior to the application of cement which is to secure the sole, and consists in the provision of a roughing tool having work-engaging portions normally embedded in yielding material, the provision of two rotary roughing tools, one with a transversely straight wide face to act on the fore part and one with a narrower convex face to act on the waist portion, a work support yielding to accommodate shoes of different widths, and means for reversing the direction of rotation of the tool while pressing sharpening means against it. Wire staples 22 are embedded in rubber blocks 50 carried by a flexible band 24, the staples being backed by a canvas band 30. Between the blocks, the flexible band is clamped to a holder 26 by studs 34 having pins engaging eyelets in the band and carried by levers 38 the inner ends of which engage an adjusting cone threaded on to the rotary spindle 20. Stitches 52 extend between the bristles and through strips of fibre on opposite sides of the rubber sections. For sharpening the tool an abrading element 120 is adjustable longitudinally in a rotatable bush 140 at the end of an arm pivoted at 124 to a member pivoted at 128, the arrangement being that the bush may be occasionally rotated to equalize the wear on the abrasive element, and that this may be swung upwardly about the pivot 124 and then horizontally about the pivot 128 before it is dropped between lugs 138 or 134 to retain it in either operative or inoperative position. A casing 90 encloses the tool except that an opening is left at the front for presentation of the work. This opening is closed when the machine is not in use by a plate 92 hinged at 104 and retained in either position by a spring device. A suction pipe 110 with adjustable damper removes debris. A work support comprises a rest 162 for the side of the upper having an abutment 164 for the tread margin, carried by a post 176 urged upwardly by a light spring 180 and capable of limited swing across the tool. The support has a finger-piece 148 so that the support and shoe can be swung together. Two tools may be provided at opposite ends of a shaft driven by a fast pulley, loose pulleys being arranged on either side of the first and driven by parallel and crossed belts to provide the reversal for sharpening.
