Abstract: 1,271,456. Teaching machines. MOSKOVSKY GOSUDARSTVENNY PEDAGOGICHESKY INSTITUT INOSTRANNYCH YAZYKOV IMENI MORISA TOREZA. 10 July, 1969 [10 July, 1968], No. 34798/69. Heading G5G. In a teaching machine, particularly one for teaching languages, of the kind in which the user is presented with a series of multi-choice questions, a window through which the set of possible answers to each question is viewed is covered by a plug-in frame 9. The machine housing (Fig. 1, not shown) contains a sequence of questions on a tape which is advanced stepby-step by the user, who has push-buttons for selecting his answers. Control circuitry is provided, and though this is not disclosed in detail, a block diagram (Fig. 2, not shown) indicates its function, viz. to identify and record correct answers. The machine provides a different pattern of correct answers for each of a plurality of different teaching programmes. Completion of the control circuitry is by way of the plugs 24 of the panel 9 and corresponding sockets 25 in the machine housing. Each panel 9 corresponds to one of these programmes, the panels for different programmes having different length plugs so that different socket contacts, and hence different correct-answer patterns, correspond to the different panels. In addition to the plugs making electric contact, the panels are mechanically retained by spring slips (Fig. 4, not shown). The machine may be used for self-instruction (in which case the user may keep selecting answers to a given question until he eventually gets a "correct " signal or alternatively may push a " prompt " button to be informed of the correct answer if his first answer was incorrect); or for test purposes, the machine counting correct (first) answers to each question. In the latter case an attempt to open the machine housing's lid, and thereby see the identified correct answers on the tape, operates a switch which causes the machine to register a " failed " test result.

Patent GB-655371-A (GB)
Title: Supervisory circuit for a start-stop telegraph system
Inventor: SNIJDERS ANTONIE
IPC: H04L25/02
Filed: 1947-12-31
Abstract: 655,371. Telegraphy. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Dec. 31, 1947, No. 34975. Convention date, Sept. 14, 1946. [Class 40 (iii)] The Specification relates to an improvement in the supervisory circuit of Specification 34841/47, (as open to inspection under Sect. 91), in which a supervisory relay is arranged to respond only to a five-mark signal preceded by a marking start element. The circuits of that Specification which have no valves are said to be not sufficiently accurate, and those with valves suffer from the defects that mark and space polarities are the inverse of the normal continental standard and that the valve operating times vary with battery voltage fluctuations. In the normal condition of the circuit shown a receive relay armature a remains on its spacing contact S and the supervisory valve B has +60 v. applied to both its anode and cathode. The grid is connected to the earthed point of a potentiometer- R3, R4 and the valve remains non- conducting. When a marking start element is received the armature a connects the condenser C1 to - 60 v., and the other plate of the condenser consequently drops to - 120 v. The diode D is now non-conducting and the point Y rises only slowly toward earth potential again over the charging resistance R1. The time constant of the R1, C1 circuit is such that after five successive marking code elements the potential of point Y rises to a point where the valve B conducts, operating a self-locking supervisory relay AR which may be used to connect in a monitor or time-indicating device, or to release a distant printer or switches at an automatic exchange. The time at which relay AR operates is determined by the time constant of the R1, C1 circuit and is independent of battery voltage. When the next spacing signal is received contact S is operated to release relay AR ready for further signalling. If a signal other than the supervisory five marks is received, the first space element renders the point Y positive with respect to the cathode of diode D which conducts and immediately charges the condenser G to earth potential, so that the circuit is again in its normal state.

Abstract: 343,472. Inductor-alternators. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitõts- Ges. ; 2, Friedrich Karl Ufer, Berlin.) Nov. 18, 1929; No. 35274. Convention date, Nov. 16, 1928. [Class 35.] The voltage of a homopolar inductor alternator having two or more generating elements and working at the maximum voltage point of the voltage-excitation characteristic, is varied by altering the relative position of the stator elements or inductors with respect to each other or by altering the magnetic leakage between the stator and inductor elements. As shown, the stator is in two parts a<1>, a<2> carrying series connected windings b<1>, b2. The rotor comprises two inductors el, e2 and the flux is established by a fixed exciting coil d. The generated voltage is a maximum when the stator and rotor parts are arranged symmetrically. If however a rotor element or a stator element is turned relatively to the other, the voltages generated in the windings b<1>, b2 add up vectorially to produce a lower total. Alternatively, the stators and rotors may be displaceable axially to reduce the effective flux. The voltage can be set initially by placing iron plates between the tops of the stator and rotor teeth to increase the magnetic leakage. Such plates on the rotor may be connected together by an annular ring so as to be axially displaceable to vary the leakage. Specification 166,224, [Class 35, Dynamoelectric generators &c.], is referred to.
