Abstract: 1,274,084. Continuous casting; casting processes A. M. GORA, B. D. KHAKHALIN, J. S. OZIMIN and V. A. DAVYDOV. 5 Dec., 1969, No. 59580/69. Heading B3F. A tundish from which metal pours continuously into a mould is fed by at least two unheated ladles filled successively but discharged partially simultaneously so that the temperature of the metal in the tundish is maintained within a given range (e.g. 1250-1280‹ C. if grey iron pipes are being cast), which is a narrower range than that through which the metal cools in each ladle. The method may be used in continuous casting plants. If three ladles are used, always at least two are discharging. In the tundish, there is mixed the metal from one ladle at a temperature below the given -range with the metal from another ladle which is at a temperature above or within the range.

Patent GB-2017452-A (GB)
Title: Television receiver simultaneously displaying several programmes
IPC: H04N5/45
Filed: 1979-03-20
Abstract: A television receiver is provided with the circuitry for displaying a second programme in a portion, e.g., one corner, of the viewing screen whilst a first programme is being displayed on the remainder of the screen. Application No. 53437/77 is referred to. An interference suppression circuit is provided to prevent superimposition of the tuner switching signal on the audio channel. This circuit includes a sample-and-hold stage (14) to which the incoming audio signal NF of the first programme is fed and which is controlled from the horizontal deflection circuit via a frequency multiplier (17) and a pulse shaper (16). This arrangement blocks the sound signal, the output signal from the sample-and-hold stage being continuously applied to the receiver's audio output amplifier through a low pass filter (15) whose upper cut-off frequency is less than half the cut-off frequency of the sampling signal. The sample-and-hold stage stores the last audio-signal value occurring prior to the beginning of the switching of the tuner to the record programme for a time which is approximately equal to the run of the duration of the square-wave pulses switching the tuner and the transient response time of the audio i-f filter. The sample-and-hold stage samples the audio signal constantly at a frequency which is such an integral multiple of the frequency of the square-wave pulses switching the tuner that the holding time of the sample-and-hold stage remains just longer than the total interference time. <IMAGE>

Patent GB-2038606-A (GB)
Title: Method and apparatus for separating and contacting friable particulate organic matter from and with liquids
IPC: A01J25/11
Filed: 1979-12-05
Abstract: The invention is concerned with the treatment of friable particulate organic matter such as cottage cheese ton curd or casein with liquids as by separation of the matter from the liquid in which it may be formed (e.g. whey) and further contacting with a liquid (e.g. a wash liquid such as water), the method and apparatus being designed to minimize break up of particles into "fines". This is achieved by providing an even non-turbulent flow of friable matter through a series of liquid contacting and separation zones. The separation of the friable matter from liquid is effected on perforate concave screens (36, 42, 48, 54) the perforations of which have outlets larger than their inlets, each screen being disposed in a generally downward direction immediately following a contacting zone in the form of a trough (40, 46, 52), each screen feeding separated matter into the next trough. The first trough may be solely a deceleration means. <IMAGE>

Title: Manufacture of an Armature for an Electric Motor
IPC: F23K5/04
Filed: 1980-04-03
Abstract: For the production of a fuel resistant armature winding (4) for an electric motor for an electric fuel pump, the armature winding (4), which is preferably preheated and rotated is treated by drop-by-drop trickling with a substance comprising a fuel-resistant epoxy resin system. The armature (1) is subsequently dried and hardened at an elevated temperature. As a result the resin coating on the armature winding (4) and/or the core insulation (3) of the armature (1) remains stable even under the action of the fuel and does not tend to break away. <IMAGE>
Patent GB-2047993-A (GB)
Title: Starting synchronous motors
IPC: H02P25/02
Filed: 1980-04-17
Abstract: A synchronisation arrangement for delaying excitation of the field winding 5 of a brushless synchronous motor, until the rotor has run up approximately to synchronous speed and is correctly positioned relative to the stator field, comprises a control unit 1 responsive to two signals derived from across diodes 13, 17 respectively to fire a thyristor 3 to connect winding 5 to the DC output of AC exciter 4 either when the slip frequency of the winding current is below a predetermined value or the rotor has synchronised on reluctance. The former condition is derived from the diode 13 signal which, providing thyristor 15 is not conducting, causes unit 1 to produce a firing pulse each time diode 13 starts to conduct. The latter condition is derived from the diode 17 signal which, provided thyristor 15 has been non-conductive for a predetermined time, causes unit 1 to produce a train of firing pulses. Operation of the unit 1, Fig. 2 (not shown) is described for the two conditions and also for other conditions such as reluctance synchronisation on the wrong pole, pull-out of the motor or variation of the winding voltage due to motor shaft swinging and rectification of harmonic voltages during reluctance synchronisation. <IMAGE>

Title: Apparatus for Continuously Measuring Optical Retardation of Synthetic Filaments or Film
IPC: G01N21/23
Filed: 1980-05-01
Abstract: Apparatus for continuously measuring the optical retardation of synthetic filaments E or film comprises source A of unpolarised or circularly polarised monochromatic light N, beam splitter O for creating two convergent beams, dichroic filters F' with polarisation planes at right angles to each other and through which the beams pass to rotating radial diffraction grating B' on a disc of transparent material at which the beams meet, the angle of convergence of the beams being such that the frequency-shifted first-order diffracted beams from the grating are coaxial. Alternatively a single beam irradiates the grating to produce two divergent beams which are focused by a lens on to a stationary grating where they are combined. The dichroic filters are then located between the lens and stationary grating. Reference and measurement beat frequency signals are generated by sampling the coaxial first-order diffracted beams before and after filaments E and are compared by phasemeter L. <IMAGE>
