Title: Improvements in or relating to electric motors having overload clutches
IPC: H02K7/12
Filed: 1963-02-07
Abstract: 1,028,672. Screw and nut gearing; overload release clutches. H. KORTHAUS, and R. WILKE. Feb. 7, 1963, No. 5042/63. Headings F2C and F2Q. [Also in Division H2] An overload clutch is associated with an electric motor which is used in mechanisms having limited travel, i.e. to open or shut valves, gates and the like, and is operative for either direction of rotation both to disconnect the drive and to switch off the motor. Motor rotor 12 is mounted on hollow shaft 13 which can move axially, relative to the output shaft, due to screw 15 and nut 16, to operate limit switches 36, 37 and is also rotatally connected to the output shaft 14 through the overload clutch device. The overload clutch comprises two identical assemblies each operative in one direction of rotation by the provision of jamming roller clutches 18, 19. Clutch plate members 20, 21 are urged against friction discs 29, 30 attached to members 31, 32 by springs 26 which bear on pressure plates 23, 24. Members 31, 32 are coupled together by studs 34 and member 32 is rigidly connected to output shaft 14. The two halves of the clutch are rotatably separated by thrust bearing 22 housed between the two pressure plates. In operation when the output shaft 14 is suddenly braked the driving clutch will slip and allow the hollow shaft carrying the rotor to screw along the stationary output shaft until the limit switch is opened to switch off the motor, the driving clutch will also be axially moved and thus mechanically disconnect the drive. Due to friction in the screw, the hollow shaft will remain axially displaced and the motor can only be started in the opposite direction when it will run to the opposite limit of travel of the driven member at which point the hollow shaft will move in the opposite axial direction, thus disconnecting the other clutch and operating the other limit switch. In a modification, for use in a wire or thread coiling drive, the screw-and-nut are designed to be friction free so that the strength of the springs used in the clutch can not only determine the maximum torque obtained but also act to return the hollow shaft to the running position so that intermittent switching in the same direction of rotation can be obtained. The output shaft may be turned manually by means of nut 38 provided on the shaft.

Title: Improvements relating to the separation of gases from liquids
IPC: B01D19/00
Filed: 1932-02-26
Abstract: <PICT:0397540/III/1> The separation of gas from liquid is effected by causing the liquid to flow along a number of narrow or shallow channels in which the turbulence of the liquid is reduced, so that the gas bubbles rise to the surface and accumulate above the liquid in each channel, and the gas and liquid separate on discharge from the channels.  The preferred apparatus comprises a nest of small tubes a within a conduit b through which the liquid flows.  To facilitate discharge of the gas the ends of the bank of tubes extend successively forward from the top downwards and the end of each tube is cut at an angle as shown at a2.  Small holes a1 in the lower part of each tube permit liquid to escape into the space between the tubes.  The turbulence of the liquid may be increased before it enters the apparatus by passage through a divergent pipe e.

Title: Improvements in or relating to alternating current signalling receivers
Inventor: RYALL LEONARD ERNEST
IPC: H04Q1/446
Filed: 1950-03-08
Abstract: 691,741. Voice-frequency signal receivers. POSTMASTER GENERAL. Feb. 28, 1951 [March 8, 1950], No. 5874/50. Class 40 (iv). A V.F. receiver arranged to guard against false operation by speech frequencies responds to the pure signal frequency only when it is preceded by a brief interval of low level signal transmission, a disabling guard voltage being maintained at the maximum value reached during signal reception until the low level signals are received, when the guard voltage is reduced below an effective value. As shown, incoming signals are applied over transformer T1 and valve V1 to a transformer T2, the valve having its amplification limited by resistors R1, R2 while the harmonics produced by limiter action are filtered-off by condenser C1. Transformer T2 supplies a bridge circuit comprising a resistor R3 and a transformer T3 tuned to the signal frequency. Balance points X, Y on the bridge feed a guard circuit comprising a rectifying valve V3 and a condenser C3, this condenser being connected in opposition to a condenser C2 supplied from transformer T3 over a rectifier Q1. At the signal frequency, condenser C2 attains a potential which drives the control grid of a valve V2 positive and thereby operates a biased relay RW by increased anode current. Condenser C3 acquires a guard potential if frequencies other than the signal frequency are received and maintains the peak voltage applied so that valve V2 is held disabled even if the signal frequency alone is subsequently received. The guard potential across C3 is only removed by reduction of the incoming signal level below a predetermined value, the condenser then being discharged through a pentode valve V4. This valve is controlled by the potential across transformer T2 over a circuit consisting of potential divider RIO, R11, rectifiers Q2, Q3 and smoothing condenser C4, the valve being normally biased off unless the transformer potential is considerably reduced. To avoid transient operation of relay RW before the guard voltage builds up across C3, the charging of condenser C2 is slightly delayed by a circuit comprising resistors R4, R9 and condenser C7. Anode potential to valve V4 is provided by a potential divider comprising resistors R2, R12, R13 and R14. According to the Specification, the pentode V4 may be replaced by a diode, the biasing circuit R10, R11, C4 being then connected in series with the cathode. Mention is made of the suitability of the arrangement for both single and multiple signal frequency applications. In the Provisional Specification, a circuit is disclosed wherein valve V4 is controlled by a further winding on transformer T2.
