Abstract: 325,033. Auerbach, R., and Steinhorst, W. Nov. 28, 1928. Emulsions, making. -In making emulsions by means of a centrifugal machine comprising a casing 2 containing a rotor 5 on which vanes 6 are mounted, aqueous emulsifying agent is admitted to the apparatus through a passage 13 and the substance to be emulsified is introduced through a nozzle 12 at the centre of the centrifugal system. In order to increase the emulsifving effect pins 14 may be provided on the casing 2 the vanes 6 being formed with spaces to accommodate such pins. The admission of the ingredients may be controlled by a plug-cock 10 having passages, which may be of rectangular section, communicating with the inlets 13, 12 respectively.

Title: Improvements in and relating to systems of electric motor control
IPC: H02P23/00
Filed: 1938-12-09
Abstract: 522,582. Control of A.C. motors; automatic control of voltage. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 9, 1938, No. 35987. Convention date, Dec. 9, 1937. [Class 38 (iii)] [Also in Group XXXV] A motor of the split-phase induction type is braked by being disconnected from the supply and having means, such as a condenser or shortcircuiting conductor connected so as to reduce the impedance of the closed stator winding. A reversible motor 1 driving a feeder voltageregulator 5 is connected through a'transformer 11 to the feeder circuit 6. If the voltage varies, relay 8 energizes one of the two relays 9, 10 which thereupon closes its upper contacts 12 or 13 and current is passed to the upper right or left terminal of the motor 1, this motor having stator windings 2, 3 and a phase - splitting capacitator 7. The motor therefore runs in a direction dependent on which of the solenoids 9, 10 is energized. When the voltage of the feeders 6 has attained its correct value, the actuated relay 9 or 10 is de-energized, and closes contacts 15 or 16 so placing a large condenser 14 in parallel with the running condenser 7. The impedance of the closed stator circuit 'is thus made low enough for the persisting flux in the rotor to induce an alternating current in the stator windings sufficient for. dynamic braking of the rotor. In other embodiments described, the operating relays 9, 10 have dash pot means for delaying the breaking of their lower contacts so temporarily leaving the condenser 7 to increase the starting torque, Fig. 2 (not shown); the braking condenser is replaced by a conductor to short circuit the running condenser 7, Fig. 3 (not shown); the addition of a centrifugal switch causes the two condensers to be in parallel until a certain speed is reached and the braking to be in two steps, the first with the two condensers in parallel and the second with both shortcircuited, Fig. 4 (not shown), by the addition of a further relay and the use of persistence of current in the two operating relays the motor is plugged for a certain period after which dynamic braking is applied, Figs. 5 and 6 (not shown).

Title: Dynamic balancing machines
IPC: H02M5/06
Filed: 1971-09-07
Abstract: 1362195 Single to polyphase conversion R L RUSSELL 7 Sept 1971 [24 July 1970] 36012/70 Heading H2F A single to three phase converter comprises three arms each comprising two impedance components equal in magnitude but having a relative phase displacement, said arms being arranged in a ring, a single phase supply being connected across any two junction points of individual arms and the polyphase supply being derived across a common neutral point and the respective junctions of the two impedance components of the arms. Each arm may comprise a resistor R and capacitive impedance Zc consisting of a capacitor in parallel with a resistor having a phase angle of 60 degrees. Alternatively, resistors R may be replaced by capacitors and impedance components Zc have phase angles of 30 degrees. The system may be balanced by use of trimming capacitors across each fixed capacitor Zc so as to equalize the three capacitances. A three phase supply is then connected via adjustable load resistors to points L, M and N and the adjustable load resistors adjusted to give equal readings across LM, MN and NL. Each capacitor is now bridged by the series combination of a fixed and trimmer resistor, the trimmer resistors being adjusted to give zero readings on three voltmeters respectively connected across sm, sn and sl. The supply and meter connections can be rotated cyclically around the ring and adjustments repeated. When the three-phase supply is removed and replaced by a single phase supply connected across LM, a balanced three-phase voltage will appear at 1mn.

Abstract: 1385111 Analogue-digital converters MULLARD Ltd 2 Aug 1972 36147/72 Heading G4H [Also in Division H3]  An apparatus producing a ten digit binary coded output B 1 -B 10  indicative of the input frequency employs a plurality of frequency discriminators D (see also Division H3) having outputs dependent on the sine and cosine functions of a frequency dependent phase angle # introduced in the discriminators. Adding and subtracting circuits in the video amplifiers produce a four level output which is sampled and stored in bi-stable stores under the control of timing circuits actuated when the input attains a certain threshold. A logic processing circuit forms the coded output from the stored values. The least significant digits B 8 -B 11  are formed from the output of the eighth discriminator while each of the more significant digits is obtained from the output of the corresponding discriminator and the three succeeding digits. The frequency of a weak back-ground signal may be measured by closing a switch S after the elapse of main pulse duration.

Abstract: 1388395 Forwarding travelling films IMPERIAL CHEMICAL INDUSTRIES Ltd 19 July 1972 [3 Aug 1971] 36416/71 Heading B5B [Also in Division B8] The longitudinal tension across the width of a continuous travelling web is equalized by passing it over a member 4. This member consists of a body portion 6, which is preferably. as illustrated, a bar, and a terminal portion 8 which is hinged to 6 and resiliently biased, for instance by a spring, towards the film. The film is withdrawn from member 4, against the bias of the terminal portion 8, so that all elements of the withdrawn web travel over paths of substantially equal lengths. In Fig. 1, a film 1 having a fold 2 is unfolded by passage over member 4, the angle # between the axes of 6 and 8 is automatically adjusted by interaction between the tension in the film and the tension in the biasing means, so that all elements of the film travel over the same length of path, even in those axes where the film has a flap of varying width. Apparatus such as this and illustrated in Fig. 5, may be used for an unfolded film, in which core wrinkles may be avoided because of the substantially uniform tension across the width of the film, the apparatus supported at the hinge, allowing the bars 20, 21 freedom to move and respond to variations in longitudinal tension.

Apparatus for supplying liquid to a workface during a machining operation comprises a high pressure pump for feeding the liquid to the work-face, means for collecting liquid from the work-face, centrifuge means for separating foreign matter from the collected liquid, and means for controlling the temperature of the collected liquid which is then fed by the pump to the work-face. In apparatus for form grinding a screwthreading tap with threads of very fine pitch, liquid, e.g. oil, is fed under high pressure between the work-face and the grinding wheel contact. Oil returning from the work-face is collected by way of conduits 2 in a housing 3 and passed to centrifuge means 4, cleaned oil discharging into a container 5, tank 6 and sump 7. The sump 7 is positioned centrally of the housing, so that oil in the sump is surrounded by oil in the housing thereby providing a heat insulating layer. A heat exchange coil 8 in the sump 7 is connected to a heat pump 9 to receive heated or cooled medium from the pump depending on the direction of operation thereof. The oil passes from the sump to a motor-driven rotary pump 1, which delivers the oil at high pressure, e.g. 1000 p.s.i., to the workface. A pump 1a is also provided for supplying oil at low pressire when high pressure is not required, e.g. for feeding to an open work-face, i.e. during milling, turning &c., or when chemical or electrical erosion is being performed. The heat exchange coil may be disposed within the container 5 and a heat insulating layer may be provided round the centrifuge means. Separate heater and cooler may be employed.
