Abstract: 1293506 Cathode-ray tube displays SUMLOCK ANITA ELECTRONICS Ltd 19 April 1971 [23 March 1970] 25035/71 Heading H4T In a system for displaying digital data signals in the form of characters on a raster scanned colour television monitor, digital data are transferred from a buffer memory to a character shift register which addresses a character memory the output of which is converted to a serial video bit stream by a video generator which is also controlled by a colour decoder coupled to the character shift register so that the characters are displayed in colour. The display 1 comprises four fields 2, each of eight characters divided into four lines 3 of twenty characters each. The input data is in the form of 7-bit ASCII code words which are stored in a buffer memory 6 providing five fields each of eighty words (characters). One of the data fields is selected and the first line (20 characters) is inserted in a recirculating character shift register 8. A read-only memory 13 has a five-by-seven matrix providing a 35-dot representation for each different character which can be displayed and this memory is addressed by each word in the character shift register in turn and by a character control generator 15 to provide a 5-line parallel output corresponding to the top line of the selected character matrices. After the character shift register has been recirculated the process is repeated but reading out the second line of each character matrix, and the process is repeated further until all seven matrix lines have been read out. The parallel outputs are converted to serial form in video generator 12 which supplies red, green and blue outputs to a colour CRT display 1 under control of a colour decoder 14. A monochrome output 230 is also provided. A timing signal generator 9 provides clock pulses for the character shift register 8 and main memory 6 and signals for controlling the transfer of data and for providing the raster scan of the display are also derived from this generator. Two modes of operation are possible, in the first mode sixteen codes not required for character representation are utilized to indicate the colour of the characters and backgrounds. The use of any of these codes replaces one of the character words causing a gap in the display and controls the colour of all succeeding characters or backgrounds as appropriate. In the second mode the background is black and the colour of the character is determined by its characteristic, i.e. capital letters, lower ease letters (displayed as capitals but in a different colour.), numerals and punctuation, and communication characters are displayed in different colours.

Abstract: 317,790. Maschinenfabrik Augsburg- Nurnberg Akt.-Ges. Aug. 22, 1928, [Convention date]. Cylinders, ports and pipes for.-In two-stroke engines, a single set of ports is used for the inlet of gas and scavenging-air to the cylinder, a valve being arranged to control the admission of both charges to the ports. Fig. 1 shows a doubleacting engine having exhaust ports d<1>, d<2> for the two ends of the cylinder, and a single set of ports c for air and gas; or there may be two sets of ports c, one for each end of the cylinder. The admission of gas and air to the ports c is controlled by a rotary valve j having a central passage m adapted to connect the gas-inlet pipe h to the inlet passage e as shown in Fig. 2. The airinlet pipe i communicates with passages at opposite sides of the passage m, and having air ports k<1>, l<1> for one end of the cylinder, and air ports k<2>, l<2> for the other end. Hence, as the valve rotates, scavenging-air is first admitted through the port k', then gas through the passage m, and finally air again through the port l<1>. This last admission of air clears the passage e of gas, and prevents loss of this gas during the next scavenging operation. In modifications, the gas-inlet pipe is arranged along the centre of the valve, and is surrounded by the air-inlet pipe.

A number of thin wood sheets are shaped into an article by inserting the sheets with adhesive between them into a mould, pressing the sheets into contact with the walls of the mould and applying a high frequency electric field across the sheets to heat the adhesive and bond the sheets together. As shown in Fig. 1, a number of veneer sheets or plywood sheets 33 having adhesive, e.g. a urea resin, on one of each pair of adjacent faces, are placed in a mould 10 having a back wall 11 fixed to a base 13, a front wall 12 slidable on the base, and side walls 20, 21 and a top wall pivoted to the back wall 11, the walls 11, 12 being electrical conductors and the other walls being insulators. A flexible rubber bag 31 within the mould is filled with pressure fluid when the mould is closed to press the sheets 33 outwardly against the mould. An alternating electric field of high frequency, e.g. 2 megacycles, is then applied between the walls 11, 12 to heat the sheets and cause the adhesive to bond the sheets together. In a modification the side and top walls are also conductive and the field is applied between the walls and an electrode within the rubber bag 31. In a further modification, the moulds, after being closed and the bags 31 inflated, are passed on a conveyer belt between two plates across which the. high frequency field is passed. The Specification as open to inspection under Sect. 91 describes also the construction shown in Fig. 9 (Cancelled) in which the heating is effected by steam instead of by a high frequency electric field, the steam circulating through passages 93 in the mould under the control of a valve 94. This subject-matter does not appear in the Specification as accepted.

Abstract: 864,385. Control valve mechanisms. HYMATIC ENGINEERING CO. Ltd. Aug. 15, 1957 [Aug. 20, 1956], No. 25340/56. Classes 69 (2) and 135. Shaft 9 may be shifted axially to a position where subsequent rotation thereof actuates one or the other of two rams 21, 22. If ram 22 is to be extended, the shaft 9, in the axial position shown, is rotated anticlockwise, opening valve 5 and closing pressurizing valve 3 through respective cams 11, 8. When the desired extension is attained, shaft 9 is returned to the neutral position, locking ram 22, and opening valve 3. If the ram is to be exhausted the shaft 9 is rotated in the opposite direction, opening valve 5, and maintaining valve 3 open. If ram 21 is to be actuated, shaft 9 is shifted axially against a biasing-spring 17 to the left. The cam 8 locked to the shaft 9 is thereby disengaged from freely-mounted cam 11 and locked to a cam 10 which now operates valve 4 upon rotation of shaft 9. Valve 3 is spring-urged to the open position, so that if excessive pressure builds up, it opens against the action of shaft 9. The invention may be extended to the control of more than two rams.
