Title: Muting circuits
IPC: H03F3/30
Filed: 1973-11-16
Abstract: 1409983 Transistor amplifying circuits SONY CORP 16 Nov 1973 [20 Nov 1972] 53387/73 Heading H3T A muting circuit comprises two voltage source terminals between which are connected in series the collector-emitter paths of two transistors of opposite conductivity type, an output terminal connected to a point in the path between the two transistors, first detecting means for detecting a D.C. voltage at the output terminal, second detecting means for detecting the voltages at the voltage source terminals, and switching means controlled by the outputs of the first and second detecting means and operative to clamp the base electrodes of both transistors to a predetermined D.C. voltage. A stereo amplifier includes a first channel comprising an output stage using complementary transistors 11, 12 and 13, 14, Fig. 1, coupled to output terminal 17 and a similar second channel having output transistors 21, 22 and 23, 24 feeding output terminal 27: diodes 36 and 46 respectively provide base biases. Power supply is via positive and negative lines + Vcc, - Vcc respectively. At switch-on, capacitors 53, 63 are not charged and consequently transistors 56, 66 are turned off: consequently if output terminal 17 or 27 deviates from earth potential either the transistor 31 or 32 is biased conductive, so clamping the base potential of the corresponding output transistors and thus the potential of the output terminals 17, 27. When capacitors 53, 63 are charged up, transistors 56, 66 become conductive and clamp the bases of transistors 31, 32 to earth potential, so they cannot become conductive. Upon switch-off, capacitors 53, 63 rapidly discharge via diodes 55, 65 respectively, so that transistors 56, 66 become non-conductive, allowing transistors 31, 32 to act as a clamp. In a modification, the output terminal (17) is also connected to the bases of the clamp transistors (31, 32) via an R.C. lowpass filter, so that if an abnormal D.C. potential appears at the output terminal during amplification, the clamp transistors come into action and protect the loudspeaker (Fig. 2, not shown). In a further modification, the output of a preamplifier 101, Fig. 3 is clamped, as well as that of the power amplifier 103. Upon switch on, transistor 117 is non-conductive until capacitor 116 charges up so that transistor 131 is biased conductive to clamp the output of pre-amplifier 101: transistor 66 is biased non-conductive and also, due to phase-reverser 134 transistor 56 also, so that the clamp circuit in power amplifier 103, which comprises transistors 31, 32 as in Fig. 1 or 2, is operative. When capacitor 116 is charged, transistor 117 becomes conductive and transistor 121 is also biased conductive due to the base current through resistor 122: transistor 132 is then biased non-conductive and transistors 56, 66 conductive. Upon switchoff, transistor 121 is immediately biased non- conductive by the charge upon capacitor 123; transistor 132 is thereby biased conductive and transistors 56, 66 non-conductive.

Abstract: 1,136,779. Sampling liquids. CESKOSLOVENSKA AKADEMIE VED. 30 Nov., 1966 [3 Dec., 1965], No. 53552/66. Heading B8N. [Also in Division B1] A method of producing accurately programmed measured quantities of liquid e.g. samples, from a flow of liquid in a capillary tube comprises feeding into the flowing liquid at programmed intervals a separating medium, such as a liquid or gas, the speed of flow of the liquid during the entry of the medium being reduced to zero or substantially zero. The liquid to be separated is fed from a container 1 via a pump 2 through a chromotographic column 3 and a pipe 4 to a point of analysis. A pump 10 is connected to a point 5 of the pipe 4 via a pipe 6. The separating medium is fed into the pipe 4 at a point 7 via a pipe 8. In operation, liquid from the column 3 flows through the pipe 4 and with a valve 12 in the pump in the position shown, a piston 11 is moved so as to draw some of the liquid in the pipe 4 into the pump chamber 13; this has the effect of stopping the flow of liquid above the point 5 so that the separating medium can be injected. The piston is then moved to force the liquid along the pipe 4. At the end of the stroke the valve 12 is rotated and the piston partially withdrawn so as to suck in a re-agent via a pipe 14 in readiness to mix with the liquid on the next suction stroke. In modifications a bellows may be used instead of the pump or the flow of liquid through the portion of pipe between the points 5, 7 may be connected by a flexible tube which can be used as a pinch-cock.

Title: Improvements in or relating to teleprinter apparatus
IPC: H04L12/54
Filed: 1965-12-17
Abstract: 1,124,497. Telegraphy. SIEMENS, A.G. 17 Dec., 1965 [17 Dec., 1964], No. 53638/65. Heading H4P. In telegraph transmitter in which a complete message is recorded on punched tape and subsequently transmitted from the tape, a programmed keyboard unit generates a message format comprising preset signals having a number of gaps for information text and variable data. Data, e.g. address and priority signals, is inserted in the appropriate gaps by selection of one of each of a group of keys on the programme unit, depression of a single address key generating a complete address in teleprinter code, and the information text is inserted by a teleprinter keyboard. When the complete message has been recorded it is transmitted, provided that for each gap in the format an appropriate key of the programme unit or of the teleprinter has been operated. The time of transmission, CR and LF signals are automatically added. A printer monitors the signals fed to the punch. To ensure that the wrong form of data is not inserted in a gap the programmed unit locks any groups of keys inappropriate to the gap under consideration. Each address may comprise a main and a supplementary section, each chosen by a single key. The message may be provided with multiple addresses, and a preset series of addresses may be selected by single key operation. The programmed unit selects the relevant teleprinter combinations from a generator by means of diodes, cores, relay matrices or selector switches.

Title: Improvements in reciprocating pumps
IPC: F04B1/32
Filed: 1969-11-05
Abstract: 1281935 Reciprocating pumps NORTH AMERICAN ROCKWELL CORP 5 Nov 1969 [5 Nov 1968] 54175/69 Heading F1A [Also in Division B6 In a rotating cylinder variable displacement swash-plate pump, a linkage controlling the inclination of the swash-plate is arranged such that it may be varied during operation, or, if the plate is immovable during stoppage, pre-set so that on re-starting assumes the pre-set inclination. The linkage comprises an adjusting cam 42 and an L-shaped member 43 pivoted at 44, an arm 46 of which is biased against the cam by a spring 48 fixed to a frame carrying the pump. The swashplate 31 is biased to maximum displacement by a spring 52 also fixed to the frame, and a pin 32 on the plate thus biased to the other arm 47 of member 43. On rotation of the cam to raise arm 46, with the plate 31 immovable, a gap is created between pin 32 and arm 47; opposite rotation creates a gap between the cam and arm 46. On starting the pump the springs act to close the gaps, spring 48 being the stronger, and thus vary the stroke. In another embodiment, Fig.9, a swashplate (61), Fig.8 (not shown) carries an extension 78 and is biased as before to maximum displacement by a spring (52); the linkage comprises a disc 66 having a pin 67 and two levers 63, 62 rigidly connected. A spring 80 between lever 62 and the swash-plate biases lever 62 against extension 78. Rotation of disc 66 in one direction, whilst the plate is fixed, opens a gap between lever 62 and extension 78, spring 80 being compressed; opposite rotation opens a gap between lever 63 and 67. On starting the pump the springs act to close the gaps, spring 80 being the stronger. In a further embodiment, Fig.11, a swash-plate 91 is controlled by a lever 92 whose position is varied by a rotatable disc 93 and pin 116. This disc is pinned at 96 to a disc 95 carrying a pin 110, a helical spring 112 between the discs biasing the pin 110 against a shoulder 111 on disc 93 and a spring 90, attached to lever 92 and the frame, biases lever 92 against pin 116. With the swash-plate fixed, disc 95 may be rotated to open gaps between pin 110 and shoulder 111, or between lever 92 and pin 116; these gaps are closed on re-starting the pump by springs 112 and 90, spring 112 being the stronger. A number of pumps may be supported within the frame, each cylinder block 12, Fig.5, carrying gearing 15 for driving the pumps. On rotation each pumping chamber is alternatively connected with inlet and outlet passages in a stub shaft 13 supporting the block, Figs.2, 3 and 4 (not shown).

Title: Means for monitoring current flow conditions in rotating rectifier systems of brushless machines
IPC: G01R19/15
Filed: 1973-11-22
Abstract: 1493107 Measuring current; testing dynamoelectric machines REYROLLE PARSONS Ltd 11 Nov 1974 [22 Nov 1973] 54178/73 Heading G1U The current in each parallel path of a rotating rectifier associated with a brushless electrical machine includes a separate transformer coupling each path to a storage capacitor. The transformer 6 output of bi-polar pulses is rectified 7 and applied to a storage capacitor 8 which thus retains a voltage as long as current flows in the rectifier 3 path. The capacitor output energizes an oscillator 12 whose radiations are picked up by a stationary aerial (31) Fig. 5 (not shown). As each of the n rectifiers has its own oscillator, a receiver connected to the aerial (31) should receive n pulses/ machine revolution. The actual number received is compared (34) to a pulse oscillator (33) output and an alarm (35) actuated if the number is incorrect. The comparator (34) is reset every revolution by a counter which itself is energized by an inductive pick-up detecting the passage of a notch on the machine rotor. The number of components mounted on the rotor may be reduced by multi-plexing any part of the system after the capacitor and transmitting coded signals over a radio transmitter along with other parameters e.g field winding temperature or voltage. At low current values a detector (39) may suppress operation of the output alarm.

Abstract: 1363206 Measuring mud properties TEXACO DEVELOPMENT CORP 27 Nov 1972 [20 Dec 1971] 54630/72 Heading G1N Apparatus for continuously measuring viscosity related properties of mud during a drilling operation comprises a pair of rotational viscometers 30, 40 operating at different speeds, their outputs being combined to give the desired property. In Fig.1 a pump 28 supplies mud to the viscometers from the inlet or outlet of drilling well 10 depending on the position of valve 26, the well and its mud supply being otherwise conventional. The viscometers rotate at 300 and 600 RPM respectively, and the mud is supplied via a conical baffle and a perforated plate to render its flow uniform, Figs.3 and 4 (not shown). Four properties may be measured by combining the viscometer output signals V 300  and V 600 , the properties being plastic viscosity, given by Á p  = V 600  - V 300 , yield point Y, given by Y = V 300  - Á p , apparent viscosity Á a , given by Á a  = ¢ V 600 , and finally the onset of flocculation which may be observed from the ratio Á p ¸Y. These properties are obtained in Fig. 5, (not shown) where resistors 76, 77 and 78 are respectively of R, R, and 2R. By reference to the equations above it will be seen that Galvo 1 displays Á p , Galvo 4 the flocculation ratio, Galvo 2 shows Y, and Galvo 3 shows Á a . These signals may be recorded on a chart as a function of time, or as a function of drilling depth, or of both, the depth being measured by a device 19, Fig.1, linked to the drill string suspension.

The air gap 2 is formed between poles 4 of the magnet, the magnetic circuit being completed by a yoke 5 and a ferromagnetic insert 6. The winding 8 is divided and connected in series with bias winding 7, and is energized by a pulse generator 9 from condenser 10 via thyristors 11, 12. Energy is returned to condenser 10 by thyristors 13, 14. The pulse generator is so controlled that thyristors 11, 12 conduct and the bias and magnetic windings 7, 8 are connected initially in series across condenser 10. For a short time after condenser 10 is discharged, the flux in the air gap 2 is substantially constant. Then thyristors 13, 14 conduct and thyristors 11, 12 switch off during a brief interval, so that the energy stored in winding 8 flows back to condenser 10. At the same time there is a fall in flux in the air gap 2, causing the electrons circulating in chamber 1 to be displaced towards a target 15. A ketatron having two chambers 1 may function similarly.
