Title: Data processing systems
IPC: G09B7/073
Filed: 1972-09-29
Abstract: 1408001 Teaching apparatus RICOH KK 29 Sept 1972 [30 Sept 1971] 45002/72 Heading G5G A teaching system comprises a central console for the teacher and a plurality of student consoles which are linked with the central console through a communication channel of scanning lines and information lines. The student consoles are sequentially addressed by the central console on a time-division basis. The central console processes received answers to determine the instantaneous ratio of the number of similar ones of the given answers to the number of student consoles in use and displays said ratio, with respect to time, on analog and/ or digital devices. Thus the central console includes a control unit for generating timing pulses, a scanner unit actuated by the timing- pulses for transmitting scanning signals sequentially to the student consoles, an arithmetic unit for processing student responses, and display units for displaying the result of this processing. The display units may comprise a panel indicating the student seats or positions, five meters for indicating the ratio of students selecting a specific answer, out of a possible five determined by the teacher, to the whole number of students, a meter for indicating the "correct response" ratio, and a panel for displaying graphically the "student response' ratio as a function of time. Each student console includes five answer-selection button, "correct" and "incorrect" answer indicating lamps, a call-button for establishing communication with the central console by way of a combined headphone and microphone, and a sound reproducing device for instructions and questions.

Abstract: 1,035,205. Surgical appliances; toys. YEDA RESEARCH & DEVELOPMENT CO., Ltd. Nov. 6, 1963 [Nov. 30, 1962; July 5, 1963 (2); Aug. 26, 1963], No's 45437/62; 26840/63; 26842/63; and 33765/63. Headings A5R and A6S. In order to propel a capsule or similar device through ducts in the body, forward motion is induced by vibration or rotation resulting from interaction between a permanent magnet within the device and an external, alternating magnetic field. The arrangement is illustrated in Figs. 2a and 2b in which a magnet 1 is embedded in a flexible body 4 having a flat tail 5. Oscillation of the magnet by an applied alternating field results in a flailing action of the tail which drives the device forward when immersed in a fluid. Various other forms of tail are also described and one other form of device has a screwlike extension so that by using a transversely placed magnet, which results in continuous rotation of the device a screw action is obtained for the forward movement. Still further forms employ laterally extending, trailing wires which drive the device forward by engaging the walls of the blood vessel &c. Such a device may be introduced into the arterial system and, in order to direct it to a desired location the patient is placed between two assemblies of coils which are suitably energized by switching, the movement of the device being followed by X-rays and a fluorescent screen. One form of device for releasing a drug at a desired location comprises a magnetized, hollow container, which serves as the magnet used for propulsion, having a closure cover made of an alloy which ceases to have magnetic properties at temperatures above 40C. This cover is held in position by the magnet until the correct location is reached and then its temperature is raised, by a high frequency field, so that it is no longer attracted. The drug enclosed in the container is thereby allowed to escape and, subsequently, the temperature is reduced to normal so that the cover is again held in position. Apart from administering drugs the device may be employed for the physical removal of obstructions in body ducts.

Title: A process for the manufacture of chromane compounds
IPC: C07D311/72
Filed: 1966-10-11
Abstract: Chromane compounds of formula <FORM:1102199/C2/1> where R1 is a hydrogen or halogen atom and R2 is a hydrogen atom or an acyl group, are obtained by cyclizing 2 - [(3R, 7R, 11R) - 3,7, 11,15-tetramethyl - 3 - hydroxy - hexadacyl] - trimethyl-p-benzoquinone in the presence of an acidic cyclization agent.  The reaction may be carried out at 0 DEG  to 40 DEG  C.  The acidic cyclization agent may be a mineral acid, e.g. sulphuric acid or phosphoric acid (preferably used with a solvent, e.g. methanol, ethanol or iso-propanol) or an alkanoic acid halide, e.g. acetyl chloride or propionyl chloride (used without a solvent). When a mineral acid is used [2R, 41R, 81R]-alpha-tocopherol is obtained directly; when an alkanoyl halide is used R1 is a halogen atom and R2 is an acyl group.  Examples are given.

Abstract: 1,195,869. Sharpening lawn mower blades. J. W. HARTLEY. 14 Oct., 1968 [14 Oct., 1967], No. 46952/67. Heading B3D. A machine for grinding the blades of lawn mowers of the type having a cylindrical cutter drum with a plurality of non-radial blades comprises :- (i) a main frame for supporting a traversing rotary grinding wheel; (ii) a sub-frame for supporting the cutting cylinder carrying the cutting blades; (iii) means for adjusting the position of the sub-frame vertically and transversely of the main frame; (iv) means for rotating the cylinder for trueing up the blades ; and (v) means for rotating the cylinder by hand during backing-off so that the grinding wheel traverses the whole length of each blade in turn to apply a bevel or taper on the trailing edge of each blade. A machine for grinding the blades a on a cutting cylinder A of a lawn mower A<SP>1</SP> has a frame A<SP>2</SP> on which a sub-frame b is adjustable both vertically, by a handle b<SP>4</SP> and gearing b<SP>1</SP>, and transversely, by a handle b<SP>41</SP> and a screw b<SP>42</SP>. Bars B, B<SP>1</SP> have their ends located in slots b<SP>13</SP> in the sub-frame, and are secured together by slotted arms and U-bolts. A lawn mower has the gear case, bottom knife plate, front roller and chain sprocket on the cutting cylinder removed and the mower is inverted and mounted with the rear roller resting on the bar B<SP>1</SP>. Brackets B<SP>2</SP> are clamped by U-bolts b<SP>10</SP> to the bar B and the mower is secured by bolts b<SP>2</SP> passing through slots b<SP>3</SP> in the brackets B<SP>2</SP> and through the holes for the front roller of the mower. The driving spindle of the cutting cylinder is aligned with a head stock C and coupled thereto by a coupling c<SP>2</SP>. The main frame A<SP>2</SP> supports a screw b<SP>5</SP> driven by a belt 6<SP>11</SP> and engaging a split nut b<SP>6</SP> on a bracket b<SP>7</SP> supporting a carriage b<SP>8</SP> travelling on rails b<SP>9</SP> on the frame A<SP>2</SP>. A grinding wheel C<SP>1</SP> mounted in the bracket b<SP>7</SP> is driven by a motor c<SP>1</SP>. The grinding wheel C<SP>1</SP> is positioned to engage a blade a on the cylinder A and the headstock rotates the cylinder, e.g. at 16 r.p.m. The grinding wheel C<SP>1</SP> is traversed and grinds each blade to render all the blades truly cylindrical. The sub-frame is then raised and moved transversely. During backing off of each blade to reduce the width of the cutting edge the cylinder A is rotated by hand, e.g. by trimming one end c<SP>3</SP> of the coupling c<SP>2</SP>, to maintain the trailing edge of each blade in turn in contact with the grinding wheel as it traverses. The cylinder may be removed from the mower and mounted in V-bearings affixed to the bars.
