Title: Circuit tester
IPC: G01R31/50
Filed: 1968-01-10
Abstract: 1,206,521. Programmed control of testing. INTERNATIONAL BUSINESS MACHINES CORP. Jan.10, 1968 [Jan.13, 1967], No.1370/68. Heading G3N. [Also in Division G1] A circuit tester for testing an ordered array of electric terminals comprises first and second test terminals and an addressings arrangement for connecting a prespecified terminal of the array to the first test terminal all terminals of lower order than the prespecified terminal simultaneously to the second test terminal, where lower order is defined as follows:- if all the terminals have addresses in the form of X, Y co-ordinates, then for any terminal P o  having co-ordinates X o Y o , lower order terminals are those for which YLYo and X takes any value, and those for which Y=Yo and X < X o . In testing a network of terminals 2-5, Fig. 2a for short circuits to other terminals on the array, the lowest order terminal in the network, terminal 002,013 Fig. 2 is connected to one side of a test unit 8, Fig.1, and all its lower order terminals are connected simultaneously to the other terminal of the unit 8; this unit then tests for short circuits under the control of a control unit 3. The terminals of the array are grouped into RATS (each RAT comprising 12 rows of terminals) and PACS (each PAC comprising 12 columns of terminals) and if a short circuit is found the control unit 3 locates the faulty lower order terminal by scanning those terminals first in RATS, then rows in the faulty RAT, then in PACS and finally in columns. After locating the faulty terminal the scan is continued to determine if there are any other short circuits. In testing the network for open circuits, the lowest order terminal is connected to one side of test unit 8 and the second terminal (030, 032) to the other side of unit 8, the open circuit test then being carried out. Then the third terminal (072, 048) is connected to the unit 8 in place of the lowest order terminal and the test repeated. Then the fourth terminal (090, 084) is connected to unit 8 in place of the second terminal, and so on, until the continuity test is completed. The control unit 3 includes an instruction and storage unit 4, Fig. 1b (not shown) which receives from a computer or tape drive (11) information as to the addresses (X, Ycoordinates) of the terminals to be tested and the type of test to be carried out. The unit 3 further includes a scan control arrangement (5) for scanning the terminals, and in addition controls selection matrices 6, 9 and 7,10 which connect the individual terminals to the test unit.

Title: An ultra-short wave transmitter-receiver
IPC: H04B1/50
Filed: 1963-01-11
Abstract: 958,634. Combined radio receiving and transmitting systems; testing radio apparatus. NIPPON ELECTRIC CO. Ltd. Jan. 11, 1963 [Jan. 18, 1962], No. 1377/63. Heading H4L. In a transmitter-receiver of the type in which the transmitter master oscillator also provides a local oscillator signal for frequency-changing at the receiver, the transmitter 22 is connected to the first arm of a directional coupler 23 which transfers power with little attenuation to a second arm connected via an isolator 27 to the aerial 30. A portion of the signal from the transmitter is passed via the third arm of the coupler 23 and filter 34, tuned to the transmitter carrier frequency, to the diode mixer 33, the received signal being supplied via an image suppression filter 32 to the mixer 33 and the resulting I.F. signal supplied to the receiver 36. When there is no incoming signal the transmitter carrier passed by the filter 34 is rectified by diode 33 and supplied to a meter 61 thus monitoring the transmitter output and carrier frequency. If the master oscillator is incorrectly tuned the carrier portion supplied to the third arm of the coupler is reflected at the filter 34 and reaches the image-frequency rejection filter 63 connected to the fourth arm, and so long as it does not equal the image frequency it will be rectified at 64 to show on a meter 65 that oscillations are present. A small portion of the transmitter output which is less than that passing to the third arm, passes from the first arm to the fourth arm of the coupler 23 and is passed via filter 63 to diode 64 which now acts as a mixer receiving a signal at the I.F. frequeney from oscillator 48. The frequencychanged signal passing through the filter 63 is thus approximately equal to the received carrier frequency and is supplied via the coupler 23 to the filter 34 which passes sufficient signal to the diode 33 for a self-check of the receiver mixer. Since a portion of the transmitter output passes through the filter 34 and is rectified at 33, if the carrier is modulated at a low level with say 50 c/s., the detected component may be amplified at 68 and compared with the original modulating tone to provide a signal to control the frequency of the carrier.

Title: Improvements in and connected with the lubrication of internal combustion engines, pumps and the like
IPC: F16N7/30
Filed: 1922-01-17
Abstract: 196,091. Hounsfield, L. H. Jan. 17. 1922. Force-feed lubricating.-In engines, pumps, and the like wherein pressure fluctuations are produced in the crank chamber, the movement of existing parts of the engine &c. is utilized to give positive control to the action of the pressure fluctuations in order to produce a substantially unidirectional circulation of lubricant from the crank chamber sump through the parts of the engine to be lubricated. The invention is described in connection with a two-stroke internalcombustion engine. Oil is forced from the sump L through a pipe K to a chamber J during the period of pressure in the crank chamber. During the period of suction in the crank chamber, the chamber J is put in communication with the hollow crankshait C, which is open to the crankchamber, through a hole H, a groove F in the bush G, and a hole E in the shaft. From the hollow shaft, the oil may pass through a hole N to lubricate the crank pin. In the application to a four-stroke engine, the position of the hole E is varied.

Title: Improvements relating to single-phase alternating current electric motors
IPC: H02K27/06
Filed: 1958-01-15
Abstract: 899,624. A.C. commutator motors. MENSFORTH, T. Dec. 15, 1958 [Jan. 15, 1958; Sept. 2, 1958], Nos. 1411/58 and 28112/58. Class 35. In a single-phase commutator motor, the field flux is maintained substantially constant and in phase with the armature voltage to give a shunt characteristic over a wide speed range, by means of a phase-shifting capacitor g in series with the field winding e, and an autotransformer h through which the voltage applied to these is varied inversely with the armature voltage. The machine is provided with a shunt commutating winding o fed from a tapping on the speed-control transformer k, and at high speed this winding acts to oppose the voltage induced in the armature winding by transformer action from the main winding e, and so suppresses current circulating under the brushes. However, at low speed, the resultant current induced between the commutator segments by the main field interferes with the field current in winding e. This effect is overcome, according to the invention, by applying a higher voltage to the field winding circuit at low armature speeds, i.e. at low armature voltages. For this purpose, the auto-transformer h is connected, as shown, so that as the armature voltage is raised, progressively more voltage is subtracted from the excitation circuit. Known resistive armature connections c, series commutating windings n, and series armature-reaction compensating windings m are provided. The machine may be reversible. The stator winding layout, Fig. 2, having nine slots per pole comprises the field winding e in six slots in each pole at the edges thereof, the armature reaction compensating winding m distributed in six slots at the centre of each pole, while the commutating windings o and n are wound round one tooth and three teeth respectively, between the poles.

Title: Improvements in and relating to the degumming of fibrous plant material
IPC: D01C1/02
Filed: 1951-01-19
Abstract: Fibrous plant material, before degumming in known manner with an aqueous solution or emulsion of a sulphated fatty oil or fat containing a water-soluble phosphate, is heated in a dilute aqueous solution of a salt of an alkali metal or of an alkaline-earth metal, which salt is substantially neutral to phenolphthalein.  The solution or emulsion of sulphated material is preferably used at raised temperature, e.g. at its boiling point at atmospheric pressure or at a pressure of 0.5-1 atmosphere higher.  The sulphated material may be prepared from a purified fish oil or castor oil.  The free fatty acid content of the oil or fat sulphated should preferably not exceed 1.5 per cent.  The plant material is pre-treated with the salt solution preferably by boiling, e.g. at a super-atmospheric pressure of 0.5-1 atmosphere. The salt is preferably magnesium sulphate or a bicarbonate of an alkali metal, e.g. sodium bicarbonate.  The sulphated degumming agent solution or emulsion may be rendered feebly alkaline before use by the addition of an alkali-metal compound alkaline to phenolphthalein, such as sodium hydroxide or sodium silicate.  In an example, ramie or ramie refuse is boiled for 2.5 hours in a 5 per cent. aqueous solution of sodium bicarbonate or magnesium sulphate, separated and washed with water.  It is then boiled for 2.5 hours under a super-atmospheric pressure of 0.75 atmosphere in an emulsion prepared in a described manner by sulphating castor oil or purified fish oil, adding sodium glycero-phosphate and then sodium hydroxide and water.  In another example, flax refuse is treated in a similar manner.  The process reduces the time required for the degumming of the plant fibres, and the consumption of sulphated degumming agent.  It is particularly applicable to the treatment of plant refuse.  Specifications 526,629, 569,333 and 706,702 are referred to.

Abstract: 412,138. Vapour burners. SVENSKA AKTIEBOLAGET GASACCUMULATOR, Lidingo, near Stockholm. Jan. 19, 1934, No. 1919. Convention date, Dec. 13, 1933. Addition to 412,064. [Class 75 (i).] In a burner having two vaporizers 10, 11 to one of which liquid fuel and air is supplied while the coke deposited in the other is burnt away as described in the parent Specification, a member 5 is operated periodically to change over the fuel supply from one vaporizer to the other by means of a tilting arm 16 carrying two communicating vessels 14a, 15<a>, which, after being evacuated, have been partly filled with liquid. With the arm 16 in the position shown heat conducted from the burner to the vessel 15<a> through a flange 23 causes the liquid in the vessel 15<a> to vaporize. The vapour condenses in the vessel 14<a> until the weight of liquid in the vessel 14<a> operates the arm 16 so that the vessel 14<a> comes to rest on a flange 22 also receiving heat from the burner. Towards the end of its movement a catch 21 on the arm 16 engages a funnel 2 which is carried by the member 5 and catches the fuel dropping from a nozzle 1. The intervals at which the arm 16 is operated may be varied by adjusting screws 24, 25 on the flanges 22, 23. Alternatively the vapour pressure produced in the vessels 14<a>, 15<a> may be utilized to drive the liquid from one vessel to the other.
