Filed: 1953-03-12
Abstract: 744,910. Transmission level measuring. BRITISH BROADCASTING CORPORATION. March 12, 1954 [March 12, 1953], No. 6889/53. Class 37. Apparatus for checking the transmission equivalent of an electric communication channel comprises at the input a device, responsive to a variable signal voltage applied thereto exceeding a predetermined amplitude, to generate a marking voltage which is transmitted to the output of the channel to operate a responsive device which applies a voltage proportional to the output of the channel at the instant of arrival of the marking voltage to a voltage measuring circuit which produces and holds a response dependent on the output voltage at the instant the input voltage exceeds the predetermined amplitude, which operates an instrument calibrated to indicate the transmission equivalent of the channel. Signals of variable amplitude are transmitted over a transmission line 10 from a transmitting station (Fig. 1) to a receiving station (Fig. 2) and the input signals are also supplied through a switch 14 optionally inserting a frequency band-pass filter network 15, amplifier 16 and rectifier 17 to charge a capacitor 18 the voltage across which is applied to a comparator 19 operating relay A when the rectified voltage on the capacitor exceeds a predetermined value. Contacts A energize slow release relay B to operate contacts B2 applying a unidirectional voltage to a phantom circuit of the transmission channel and to operate contacts B1 to energize relay C over capacitor 21 to discharge capacitor 18 over contacts C1 whereby all relays are de-energized and a short mark pulse is transmitted to impulse relay D at the receiving station, the output signals of which are supplied through switch 14<SP>1</SP> optionally inserting a frequency band-pass filter network 15<SP>1</SP>, amplifier 16<SP>1</SP> and rectifier 17<SP>1</SP> to capacitor 18<SP>1</SP>. Energization of relay D closes contacts D1 and D2 to energize relay E and slow operating relay F. Contacts E1 close to connect a valve voltmeter 22, shunted by a small high-insulation capacitor across capacitor 18<SP>1</SP> over contacts G1; relay E is then de-energized over contacts F2 to disconnect the valve voltmeter and relay G is finally momentarily energized over contacts F1 and associated capacitor to discharge capacitor 18<SP>1</SP>. The valve voltmeter maintains its indication until arrival of the next marking pulse, and may be directly calibrated in transmission equivalents. Supplementary relay circuits may be provided to operate an alarm when the transmission equivalent deviates from predetermined limits, or to vary the gain of local amplifiers to compensate the deviation. The system is also applicable to radio link channels.

IPC: H02K15/12
Filed: 1963-02-25
Abstract: An electrically-insulated stator assembly for an electric motor is made by forming a fluidized bed of particles of a pulverulent thermosetting material which is polymerizable to form a synthetic resin, heating the stator assembly to a temperature at which said particles will melt, coalesce and undergo partial polymerization only, immersing the stator assembly in the fluidized bed while at said temperature for such a period as to build up upon the slots of the stator assembly and at least the surfaces of the stator adjacent the slots a coating having the desired thickness of synthetic resin in a state of partial polymerization, removing the stator assembly from the fluidized bed and subsequently embedding it in a synthetic resin-forming moulding material and finally curing the whole assembly to form an integrally bonded unit.  The resins used for the fluidized bed and the final moulding may be epoxy resins, and the bed may be fluidized by heated air.  The stator may be heated by an electric heating element or by induction.  The internal bore of the stator may be masked during the coating: and the assembly may finally be cured by heating to an elevated temperature.  Specifications 949,476 and 949,477 are referred to.

BLADES: The blades 10 are made of stainless steel and are about 10 to 25 thousandths of an inch thick and have a scalloped cutting edge (12), Fig. 1 (not shown) and are mounted on an upper frame 31 and in a V-formation such that they overlap by the required amount. The frame 31 has sides having a U-shaped cross section and reciprocates on guide rods 34. A lower frame 31A similar to the frame 31 also reciprocates on the rods 34 and its blades 10 are interleaved with those of the frame 31 so that adjacent blades 10 reciprocate in opposite directions. The blades 10 have studs (13) which engage hooks carried by the frames 31, 31A. FRAMES: The frames 31, 31A are roughly rectangular in shape and are V-shaped in plan and include an angle which will give the required overlap of the blades 10. The frames 31, 31A are mounted on vertically reciprocable rods which are reciprocated by cranks rods 24, 25 driven by a wheel 22. CONVEYERS: Loaves of bread are fed into the machine by an endless chain conveyer 50-55, Fig: 25. A vertically reciprocable gate 56 is coordinated with a bread-wrapping machine and allows loaves to pass at given times to a conveyer 66-68, 70-75 where a cross-bar 66 pushes a loaf on to support plates 69, 69A between which the blades 10 reciprocate and cut the loaf while it is held down by a guide-plate 90. The loaf is then conveyed over a conveyer 76-85 to the wrapping machine.

Abstract: 886,354. Sheet-delivery apparatus. COMPAGNIE DES MACHINES BULL. March 5, 1959 [March 6, 1958], No. 7713/59. Class 100(1) [Also in Group XIX] In a record card machine an indication that the card-receiving pocket is full is provided by a lever 3, Fig. 1, against which the cards above a certain level bear and displace to close a contact 5. The first cards 6b to enter the pocket pass the lever without displacing it and fall to the bottom of the pocket. When the cards reach a certain level, following cards 6a can no longer tilt sufficiently to get past the lever and come to rest supported by it, and the weight of a certain number of these cards overcomes the force of a spring 4 to close the contacts 5. This may interrupt the feed of cards. The lowermost cards 6b may be withdrawn sideways through an opening in the wall of the pocket so that cards 6a fall to the bottom and the contacts 5 open to re-start the card feed. The lever 3 may be on the opposite pocket wall as shown in Fig. 3, so that the uppermost cards bear against it by a sliding action on the lower cards. In another modification two pockets each with a vertically displaceable floor are arranged side by side. Cards normally feed into the first pocket, but when this is full the lever 3 is operated to swing a deflector flap to such a position that succeeding cards pass to the other pocket.
