Title: Improvements in Self-regulating Dynamo-electric Machines.
Inventor: HOLT WILLIAM
IPC: H02K23/20
Filed: 1917-05-22
Abstract: 115,509. Holt, W., and Brooks, B. May 22, 1917. Exciting.-To obtain a constant voltage or current from a self-regulating variable-speed dynamo, the cross-magnetization due to the armature load current is wholly or partially neutralized by means of a compensating winding on the field magnet, a closed winding or circuit is provided on the armature to produce a second cross-magnetization, and supplementary brushes are utilized for demagnetizing the main field-magnet poles. In one modification, Fig. 1, a separate short circuited armature winding b of high resistance and as non-inductive as possible produces by its rotation in the field of the main poles d a magnetic field received by supplementary poles c. The coils of the main armature winding which are under the poles e are spanned by two separated main and supplementary brushes f, f<1> which are electrically connected so as to produce a demagnetizing effect on the main poles d, as described in Specification 26880/10. Compensating-coils g are mounted on the poles e to neutralize or under or over compensate the field due to the load current. The salient poles c may be omitted by bringing the sides of the fieldmagnet yoke close to the armature; a few! series turns may be provided on the main poles d. Instead of directly short-circuiting the brushes f, f<1>, they may be connected through coils on the poles d; or the exciting-coils c may be connected across the main and supplementary brushes situated on opposite sides of a main pole d. The brushes f<1> may be placed under the poles d. The winding b may be joined through slip-rings to a variable resistance. In place of the alternating- current winding b, a second commutator winding b', Fig. 5, may be provided on the armature, having its brushes b<2> either short-circuited or connected through a resistance b<3>. In further modifications, the armature is provided with a single commutator winding, either having tappings connected through resistances as described in Specification 15686/13, or having the main brushes cross-connected through a resistance.

Title: Improvements in and relating to the reconstruction of locomotives
IPC: F01L31/16
Filed: 1935-03-09
Abstract: 449,493. Steam engines. LENTZ, H., 74, Kurfurstendamm, Halensee, Berlin. March 9, 1935, No. 7451. [Class 122 (ii)] In a locomotive adapted to work with highly superheated steam wherein the slide-valve mechanism is replaced by poppet valves and valve-gear, balanced double-beat inlet and outlet valves 19, 21 with inwardly directed spindles journalled one within the other and guided by a cross-piece 33 are inserted in each end of the bore 5 of the valve chest and are operated by oscillating cams arranged in hollow covers 22 which are divided in the central plane of the axis of oscillation and are mounted on the old intermediate pieces 8 and close the bore 5. The old slide-valve liners and chest covers are removed. Steam supplied drop by drop with lubricating oil is supplied to the cross-piece 33. The exhaust pipe connections remain unaltered. The cams comprise exchangeable shoes 24 which act like roller levers, and are mounted on shafts 23 so that their lifting-surfaces pass through the axis of oscillation. Intermediate roller levers 25, 26 operate the valves which are quickly opened and quickly closed without shock. The inlet valve is housed in an insertion piece 18, and the exhaust valve in a piece 20 housed in the part 8. The lever 26 through a hollow push bar 28 and a collar 28<a> moves the outlet valve 21, the spindle 29 of which slides in the bar 28 and in a bore 30 in the insertion 18. The inlet valve spindle 31 extends through the hollow parts 28, 29 and carries a shoe 31<a> which engages lever 25, and at the other end enters the cross-piece 33. The steam acts directly on this spindle, and, through bores therein, in space 30 on the outlet-valve spindle. The two arms on shafts 23 are connected by rod 27. The closing pressure on the valves at one end of the cylinder assist the opening of the valves at the other end. The admission valves act as safety valves. The old safety valves are dispensed with. For idle running, the valves remain open when the steam to spaces 32 is cut off. The engine can be used for slow or high speed by suitably selecting the shoes 24. Specifications 413,485 and 449,492 are referred to.

A load interrupting switch comprises a main blade contact 14 and main fixed contact 13, a resistor 18A connected at one end with the fixed contact 13 and an auxiliary switch blade 31 connected to the other end of the resistor and engageable with the main blade 14 in the closed position of the switch and during the initial stage of the opening movement. When the main contacts separate a parallel circuit still remains through the main blade, the auxiliary blade and the resistor section 18A thus preventing arcing at the main contacts. The auxiliary blade remains in contact with the arcing contact 15 of the main blade, as the latter pivots upwards, until it is arrested by a stop 23 when the two blades are separated to establish an arc between them. During further movement of the main blade 14 the arc is successively transferred to arcing contacts 24, 26 respectively inserting further resistor sections 18B, 18C in series with the arc. A corona shield 22 surrounds the auxiliary blade 31 in its open position.

Title: Hydraulically operated casket table for hearses
IPC: A61G21/00
Filed: 1937-03-15
Abstract: 479,169. Hearses. RICHTER, E. March 15, 1937, No. 7586. [Class 108 (i)] In a hearse of the type in which a casket table is supported for movement back and forth, a fluid-operated piston and cylinder mechanism is operatively connected to the table to communicate movement thereto and means is provided for supplying working fluid under pressure selectively to either end of the cylinder to move the table in either direction. The casket table 27 is adapted to be guided so that it may project out of either side door 25 or out of a rear door and to this end is provided on its lower side with three projections 29, 30, 31 taking into a central guide 36 having lateral guides formed in the platform 28. The front projection 29 takes into a swivel guide piece 32 which is linked to the seats 23, 24 so that the forward movement of either moves the guide 32 by links 54, 54b, 54c, Figs. 1 and 3a, so that forward movement of the casket table causes it to move out of the appropriate side door, the middle projection 30 moving along the appropriate branch guide 35 while the rear projection remains in the central guide 36. The rear projection is connected by a link 39 to a crosshead 40 slidable on the hydraulic cylinder 41 the cross-head 40 being connected to the piston rod 45 by means of a cross-head 46 and guide tube 47, Fig. 4. To operate the casket table the appropriate seat 23 or 24 is moved forwardly to turn the swivel 32, the arm 54c of which contacts with a contact 73, and on movement of the starting lever 61, Fig. 20, to operate the valve 67 the contact 78 of the electric circuit is closed and the motor 70 starts driving the pump 68 to force pressure oil through duct b to the rear of the piston 44 in the hydraulic cylinder 41. At the completion of the movement of the casket table a stop 77 on the piston rod 45 causes the lever 75 to break the contact 114, 116 and stop the motor. To reverse the movement the lever 61 is moved to cause the valve arm 66 and its conductor 81 to contact with the conductor 82 when the motor 70 restarts in the same direction, but the pressure oil due to the reversal of the ducts in the valve 67 is then forced to the other side of the piston 44, a stop 76 on the piston rod 45 breaking the circuit through lever 75 and contacts 114, 115 at the completion of the run. The valve 67, Fig. 8, comprises a housing cap 85 and a spring-pressed valve plate 86 such that if the casket table is moved by the hand at a faster rate than that which obtains from the hydraulic system the valve plate 86 is forced off its seat by the extra pressure and the drain side of the cylinder 41 is opened to the reservoir. When the extra rate caused by manual operation is stopped the valve plate 86 reseats itself and the hydraulic operation resumes. When hand operation alone is contemplated the lever 61 is moved to neutral position so breaking the electric circuit and placing the valve in the appropriate position.

Title: Improvements in or relating to a method of lowering and raising electrodes in electric smelting furnaces
IPC: H05B7/109
Filed: 1963-02-26
Abstract: 986,295. Fluid-pressure rams. ELEKTROKEMISK A/S. Feb. 26, 1963 [March 8, 1962], No. 7706/63. Heading F1P. [Also in Division H5] An electric smelting furnace has a vertical electrode 1 supplied with current by means of a releasable electrode holder 2, electrode 1 being also provided with a releasable clamping ring 5 connected to double-acting hydraulic/pneumatic rams 7 by which ring 5 and electrode 1, when gripped by ring 5, can be displaced vertically relatively to the stationary holder 2, and in which rams 7 are actuated by a combination of hydraulic and pneumatic pressure in a pressure system which employs compressed air as an air cushion to support the electrode during its descent. As shown, holder 2 is supported by suspension casing 3 and suspension frame 4. When electrode 1 is to be lowered, the pressure of holder 2 on electrode 1 is reduced, the electrode being gripped by ring 5, valves 17 are closed and compressed air is forced through pipes 14 and valves 16 into cylinders 6 which forces pistons 7 downwards taking ring 5, connected to pistons 7 by frame 8, and electrode 1 downwards, the oil in cylinders 6 being forced through valves 13 and pipes 12 into closed vessels 9. As the oil level in vessels 9 rises, air is compressed above the oil acting as an air cushion. At the bottom of the stroke, holder 2 grips electrode 1, ring 5 is released and valves 16 opened to the atmosphere, the compressed air cushion then expands and forces the oil back through valve 11 and pipe 10 into cylinder 6 pushing piston 7 and ring 5 upwards, until at the top of the stroke, ring 5 again grips electrode 1. When electrode 1 is to be raised, ring 5 is released and valve 17 opened so that air may flow freely out of vessel 9, which causes ring 5 to sink under its own weight forcing the oil into vessels 9. At the bottom of the stroke, ring 5 again grips electrode 1, holder 2 being simultaneously released, and compressed air is forced through pipes 15 pushing the oil back into cylinders 6 raising pistons 7 and electrode 1. Ring 5 can be caused to grip the electrode in any known way, e.g. rubber bags or sheets exposed to hydraulic or pneumatic pressure.

Title: Article sorting system
IPC: B07C3/02
Filed: 1970-02-18
Abstract: 1281963 Sorting postal mail; endless conveyers INTERNATIONAL BUSINESS MACHINES CORP 18 Feb 1970 [24 Feb 1969] 7722/70 Heading B8A An article sorting system comprises a first storage station including a plurality of article storage units 34, a feed system for sorting input articles into the storage units in accordance with addresses carried by the articles, a conveyer carrying storage units 37 arranged to receive articles selectively discharged from the units 34 of the first storage station and to transfer them to a second storage station which includes a plurality of article storage units 40 arranged to receive articles selectively discharged from the conveyer storage units, and a control unit 39 incorporating a data store. The latter is operable to assign dynamically and store, data relating addresses to the storage units, and to control input sorting and subsequent discharge of articles from the storage units thereby to determine the paths of articles through the system. The control unit 39 is arranged to keep running counts of articles in the storage units 37 and to control the discharge of articles therefrom in accordance with the counts. The control unit is arranged to cause discharge of articles from at least one of the storage units of the first storage station when more than a predetermined number thereof contain articles. In operation, articles of different categories are sorted into corresponding storage units 37 of the first storage station, and when a particular unit 37 is filled, a further unit 37 is assigned by the control unit 36, to the same category to receive further input articles in this category. As applied to the sorting of postal mail, the distribution of letters to the units 37 is controlled by a manually operated keyboard 31. Alternatively, the addresses may be read by magnetic or optical sensing means or by an optical character reader. The units 37 may have destinations, according to particular addresses, assigned to them by the control unit 36, but these may be altered in accordance with the inflow of letters to the keyboard 31. The contents of the conveyer storage units 37 are automatically tied into bundles at 42 and the bundles are carried round on to the lower run of the conveyer. Folding partitions of the units 37 are folded down by the action of a fixed guide 46 of the conveyer, the arrangement of the lower run of the conveyer being as shown in Fig. 4. The folding partitions are normally retained in a position in which they close their respective units 37, by the action of wheels 52 on the partitions which run on a rail 59. The latter has pivotable sections which may be displaced (as shown in Fig. 4) so as to allow a partition to fall down under gravity and so cause discharge of the mail into a designated unit 40.

Title: Improvements in temperature controlled valves for regulating fluid flow
IPC: G05D23/12
Filed: 1948-03-15
Abstract: 654,427. Temperature-responsive actuating-elements. WEST, C. A. March 15, 1948, No. 7734. [Class 64(ii)] [Also in Groups XXIX and XXXII] The pressure exerted by a bellows 25 of a thermally-actuated unit on a valve stem 14 by way of an operating stem E is controlled by at least two springs A, B in series, there being, between adjacent spring ends, an intermediate guide member consisting of two collars 31, 32 carrying a bearing 37 slidable up and down the operating stem. The springs are shown as coiled in the same manner but they may be oppositely coiled. The thermally-actuated system may be detached from the valve and control spring system by releasing a ring 10a to which are secured the bellows 25, an enclosing cup 27 and a capillary tube 55 leading to the bottom of a pilot bulb D, responsive to the temperature of a heating or cooling medium controlled by the valve 12. On a rise in temperature, liquid forced up the tube 55 to the space between the cup 27 and the bellows 25 and its guiding cap 23 forces the cap down and depresses a thrust member 21, the operating stem E to which it is attached and the stem 14, to close the valve 12. A lost motion spring 20 takes up any excess depressive movement. The compression of the springs A, B is adjusted by a nut 35 forming a lower plate for a ball thrust bearing 34a the upper plate 34 of which constitutes the lower bearing of the spring B. By screwing the nut 35 up a sleeve 44 fixed to a cross bar 11a of the valve chassis 10 the springs are compressed. A bearing bush 19 centres the operating stem E in the fixed sleeve 44. In a modification the springs are of equal diameter and the capillary tube communicates with a bore of a fixed central hub in the bellows. Furthermore, an increase in pressure depresses the cup, which is inverted with regard to the disposition shown, and the operating stem attached to the cup in this case is forced down.

Heading B7D.  The air chamber of hydropneumatic suspension springs 1, 2 are communicable through valves 11, 12 and pipeline 10 with a hydropneumatic accumulator 3 including a liquid chamber which contains a volume of oil adjusted under the control of a valve 4 to maintain a constant suspension height. The valves 4, 11, 12 are actuated by pressure signals received through lines 9 from an hydraulic transmitter cylinder 8 which detects the distance between the vehicle body and an axle directly or is sensitive to pressure changes created in the springs 1, 2 by restricting the movement of the diaphragms separating the air and oil chambers therein by means of perforated resilient inserts (Fig. 2, not shown). The cylinder 8 transmits a signal upon a change of body height to open the valves 11, 12 and operate the valve 4 either to supply oil to the accumulator 3 from a pressure source 5 or exhaust oil from the accumulator to a reservoir 6.
