Title: Improvements relating to drives utilising electromagnetic slip couplings
Inventor: CARNEGIE HERBERT STIRLING
IPC: H02K49/02
Filed: 1950-04-28
Abstract: 682,108. Electromagnetic clutches; transmitting mechanical power. ENGLISH ELECTRIC CO., Ltd. April 30, 1951 [April 28, 1950], No. 10524/50. Classes 35 and 38 (iv). A load whose torque rises with the speed, e.g. a fan, is driven by a variable speed, changepole motor through an electromagnetic slip coupling of such a characteristic that its torque rises quickly to a maximum with increasing slip and then remains substantially constant up to the maximum slip. The change-pole driving motor M is of 3-phase squirrel-cage type having high and low speed windings W<SP>1</SP>, W<SP>2</SP> selectively energized through contactors Cla, C2a. The control circuit is arranged to energize the low-speed winding during low settings of the coupling field rheostat RH1, and the high-speed winding during the higher settings, a time delay occurring between the disconnection of one winding and the connection of the other. The motor is started by pressing button St which energizes a self-holding relay IF which closes contacts IF2 which connect the rheostat to the supply, and contacts IF3 which energizes a time-delay relay 3N which, after the delay has elapsed, closes contacts 3Na thus energizing relay C1. This relay in turn closes contacts C1a, so that the motor starts on low-speed winding W<SP>1</SP>. The fan may now be started by moving the rheostat slider from " A " towards " B " and so energizing the field winding W<SP>3</SP> of the coupling. Movement of the slider to position B " closes contacts LS3a to energize relay 5N. This opens contacts 5Na, thus de-energizing relays 3N and C1 thus opening contacts C1a to de-energize W1, and closing contacts C1C so that relay C2 is energized and closes contacts C2a to energize the high-speed winding W2. Further motion of the slider to C increases the coupling excitation to its maximum. Speed is reduced by motion of the slider from C to A, and at the point D contacts LS2a are opened, thus de-energizing relay C2 and motor field winding W<SP>2</SP>. This also closes contacts 5Na which, since C2b are already closed, energizes the time-delay relay 3N to re-energize relay C1 and so reconnect the low-speed winding W<SP>1</SP>.

Title: Improvements in or relating to mobile watering-jets
IPC: B05B3/16
Filed: 1944-06-02
Abstract: 587,166. Watering sprays. KUGLER FONDERIE ET ROBINETTERIE SOC. ANON. June 2, 1944, No. 10650. Convention date, May 3, 1943. [Class 69 (iii)] Water is automatically distributed in Lissajous curves to cover a substantially rectangular area from a nozzle 1 striking alternately the surfaces 7 and 8 of a wedge piece 5 oscillated by the water about an axis 6, in an arm 4 which is also oscillated by the water about a knife edge 3. The inertia of an adjustable counterweight 12 on a pin 11 in the wedge influences the oscillation of the wedge between stops 9 and 10 while a larger adjustable counterweight 13 on the arm 4 influences the oscillation of the arm 4 carrying the pivot 6 of the wedge so moving the wedge bodily so that the combined action of the smaller amount of inertia of the wedge &c. and the larger amount of inertia of the weight 13, arm 4 and attachment, acts to give continuous swinging motion. In another form, Fig. 2, designed to ensure uniform watering, the jet is directed up through a pipe 25 which rocks about an axis 21 which also rocks about an axis 23 at right angles thereto, the stream of water then issuing through an outlet 26 also rocking about axis 28 and 30. An adjustable weight 32 is also provided. The rocking of pipe 25 &c. is limited between stops 33 and cushioned by springs 34. 22 and 29 are gimbals. In another form, Figs. 3 and 4, the jet from 37 through 45 when upright, causes the rocking part 43, when inclined, and its counterweight arm 61, to oscillate with a longer period than the oscillation of the arm 42. The arm 42 oscillates between stop pins in recesses 49. The oscillations, of the part 51 attached to 42 imparted through ratchet or friction rollers 53, 55, angularly displaces the piece 52, thus turning it angularly round the swivel pin 57 in the course of which the stop pin 59 moves along the slide bar 60 which causes the body 38 to swing round the axis 39, Fig. 3. The range of this swing can be regulated by placing the stop pin 29 in one or other of the threaded holes 58, the clearance between the stop pins 50 and the recesses 49, 62 allows the device to restart a stopped oscillation without outside help.

Title: Improved means for the protection of electrical installations
IPC: H02H7/22
Filed: 1933-04-11
Abstract: 417,338. Protective cut-out arrangements. FENNELL, W., Waverley, Chester Road, Sandiway, near Northwich, Cheshire. April 11, 1933, No. 10750. [Class 38 (v).] A wiring system has its insulated conductors enclosed in insulated conducting shields, each of which is connected to a potential indicator, recorder, or relay and is charged flexibly through a high resistance or impedance at a potential differing from that of the enclosed conductor or conductors. Leakage from any conductor to a shield alters the potential of the latter so as to give an indication of the leakage or operate a relay. Conductors a, b are each surrounded by a shield S, which is connected to a point m on a potentiometer P of suitable resistance placed across the conductors, while between a, S is connected an electrostatic voltmeter V, or a recording instrument, indicator, or protective relay. Alternatively, the part r of the potentiometer between m, a may be replaced by the meter resistance itself. The effect on the meter, relay &c. will be modified by occurrence of a leak in the insulation between the conductors and shield. Where a sectionalized shield is employed, the sections may be connected in succession to the potentiometer by a oommutator switch rotated or oscillated by hand or by a motor, the resistances being preferably chosen so that the shield-section potentials are constant provided no fault exists. In Fig. 4, the indicator V forms one resistance r, the shields of a section of circuit are connected in series, and the other resistance r<1> is connected to the tail-end of the circuit. Thus V also indicates when a break in the continuity of the shield-sections occurs. The latter may alternatively be connected in parallel. Where several shields are connected to a central indicator, pilot wires are employed for this purpose and are themselves provided with a shield and indicator. Specification 311,792, [Class 38 (v)], is referred to.

Title: Improvements in or relating to the protection of alternating current generators
IPC: H02H7/06
Filed: 1959-04-01
Abstract: 858,646. Protective cut-out arrangements. WESTINGHOUSE ELECTRIC CORPORATION. April 1, 1959 [April 3, 1958], No. 11011/59. Class 38 (5). [Also in Group XXXV] In a system wherein a number of alternating- current generators operate in parallel, protection against over or under excitation is obtained by means which are responsive to the division of reactive load whereby a generator with a faulty excitation is removed from the bus-bars. Two alternating current generators 1, 2 are connected to common load bus-bars 3 by way of circuit-breakers 4, 5 respectively, each having a closing coil 6. When the excitations of the generators are normal the voltage outputs of the transformers 12 and rectifying bridges 15 are such that neither the over-voltage sensing devices 16 nor the undervoltage sensing devices 18 are able to operate the circuit-breaker trip coils 7. Should the excitation of one machine become faulty the division of the reactive load will alter whereby the voltage outputs of the rectifying bridges 15 will alter and should these voltages vary outside of predetermined limits either the device 16 or the device 18 associated with the faulty machine will operate to open the associated circuit-breaker 4 or 5. In order that the generator with faulty excitation may be selected and removed from the bus-bars whilst maintaining the other generators connected thereto, current transformers 22 are provided and connected in a loop circuit 23, 24. When a generator excitation becomes faulty a current circulates in the loop 23, 24 which serves to energize saturable transformers 28. The outputs of the saturable transformers 28 are applied to adjustable resistors 29 so as to modify the voltages applied to the rectifying bridges 15 and hence the voltages to which the sensing devices 16, 18 respond. By using transformers 28 which saturate, the system is made insensitive to changes in real load. If desired, the field winding 8 of the faulty generator may be deenergized at the same time as the circuit-breaker associated with the generator is tripped. Specification 745,964 is referred to.

Abstract: 978,557. Fluid-pressure brakes. BIRMINGHAM SMALL ARMS CO. Ltd. June 28, 1961 [March 30, 1960], No. 11117/60. Heading F2F. [Also in Division B8] A tripper for a conveyer belt (see Division B8) comprises an hydraulic system (shown diagrammatically) in which a rotary pump 8 connected to an oil reservoir 9 is driven by one of the belt drums (not shown). Oil from the pump 8 is led to a two-way junction 15, one branch leading to a cylinder 16 the piston 17 of which is urged by a spring 19 to apply a brake 18 of the tripper, the other branch leading to a main control valve 20 having two outlets 21, 22. When the oil passes through outlet 21 it returns to the reservoir 9 and the pressure is insufficient to release the brake 18. When the oil passes through outlet 22 it is directed through a speed control valve 23 to a reversing valve 24 with ports 25, 26 through which it drives reversing motor 13. A relief valve 27 is connected between ports 25, 26. When the oil is directed through outlet 22 the pressure rises sufficiently to take off the brake 18 which then acts as a safety device in case of oil pressure failure.
