Title: Preparation of transition metal organic phosphite complexes
IPC: C07F9/50
Filed: 1961-07-20
Abstract: An aldehyde and/or an alcohol is obtained by reacting an olefin with carbon monoxide and hydrogen in the presence of a complex containing in the molecule a transition metal having an atomic number from 23 to 32, 40 to 51, or 57 to 84 and at least one molecule of a biphyllic ligand containing trivalent phosphorus, arsenic or antimony as a catalyst. The preferred transition metals are iron, nickel, ruthenium, rhodium, palladium, osmium, iridium, platinum and, particularly, cobalt. A preferred class of catalysts are those having the formula [(Rz1A)x-L-Ry]pM(CO)n in which (Rz1A)x-L-Ry represents the biphyllic ligand, M is a transition element as defined above, L is phosphorus, arsenic or antimony, R and R1 are alkyl, aryl, aralkyl or alkaryl groups, A is oxygen, nitrogen or sulphur, x is 0-3, y is 3-x, p varies from 1 to the co-ordination member of the transition metal, n + p is equal to the co-ordination number and z is 1 where A is oxygen or sulphur or 2 when A is nitrogen. The olefines used as starting materials may be branched or unbranched, aliphatic or cycloaliphatic hydrocarbons having one or more double bonds. The olefins may also contain functional groups, e.g. hydroxy, chloro, ester or carboxylic groups. Suitable starting materials are, for example, ethylene, propylene, butylene, 1-pentene, 4-octene, 1,3-butadiene, 1,5 - hexadiene, polybutadiene, styrenebutadiene copolymers, cyclopentene, cyclohexene, cycloheptene, 2,5 - bicyclo(2,2,1)-heptadiene, 1,4,4a,5,8,8a - hexahydro - 1,4,5,8-dimethano - naphthalene, vinyl chloride, allylacetate, diethyl maleate and allyl benzene and they give the corresponding aldehydes and alcohols.

Patent ES-291874-A1 (ES)
Title: Improvements in or relating to loose-leaf binders
IPC: B42F13/16
Filed: 1963-09-21
Abstract: A loose-leaf binder comprises two or more links each including a central base portion 7 and two prongs 8, 9 extending from said central base portion, one or both of said prongs having an outer end portion which is inclined to a plane normal to the central base portion and passing through the inner ends of the prongs. As illustrated in Fig. 6, the outer end portions of both prongs 8, 9 are inclined to said plane. The links are pivotally mounted on a guide 2 by means of the lower ends 8a of prongs 8 which engage apertures 5 in the guide. The latter is formed from resilient material and shaped to provide a gripping portion 3 to prevent accidental disengagement of the links from the guide. Each bar 7 has a stud on its underside, such as the lower end 9a of prong 9, which engages an aperture 6 in the guide to lock the link in its " closed " position, as illustrated in Figs. 6 and 10. In this position, the free ends of the prongs 8, 9 overlap when viewed along the longitudinal axis of the guide, Figs. 15 and 16 (not shown). Thus sheets filed on prongs 8 may be slid over on to prongs 9 without becoming disengaged from the prongs at any point. Sheets filed on the device illustrated in Fig. 6 would have at least eight filing perforations. To move the binder to its " open " condition, wherein sheets may be removed from, or inserted into, the binder, the studs are disengaged from apertures 6 and the links pivoted in the direction of arrow f, by a connecting rod 11. A V-shaped step 10 on each bar, which abuts the free edge of gripping portion 3, limits the pivotal movement of the link. Various shaped prongs are illustrated and in particular one prong of each pair may comprise a straight post.

The wedge member 23 is slidably mounted on a spindle 21 attached to a bracket 22 which is mounted on pin 15. A rack 18 is secured to arm 13 and has serrations 19 which are engaged by serrations 27 formed on the wedge member 23. The surface of the member 23 contacting the arm 14 is curved. The device is bolted in position through hollow pin 15. In a modification, an arm 13a is formed with lugs 29, 31 having elongated holes through which a spindle 33 projects, and an arm 14a has a curved portion 34 so shaped that the wedging action is increased as the wedge member 23a moves closer to the head of spindle 33. Several modifications having means for cocking and locking the device in an energized state, i.e. with the helical spring fully compressed, are described. A pivoted tensioning strip may be utilized.

Title: Buffered teletypewriter device
IPC: H04L17/00
Filed: 1968-03-20
Abstract: A transmitting and receiving terminal for digital data and which is operable in various modes includes first and second registers 13, 17 and a buffer store 15. Data from store 13 passes via buffer 15 to store 17, from buffer 15 to store 13, and from store 17 to store 13, under the control of unit 23. If a polling signal is received from a distant station its arrival in store 17 causes the terminal to transmit an appropriate response, and then to transmit or receive data. Entry mode.-Parallel-bit characters from teleprinter 11 are read in to store 13, which passes each character in serial-bit form to multicharacter magnetic core buffer 15. Print out mode.-Serial-bit data from buffer 15 is read out to store 13 which passes each character in parallel-bit form to the printer 11. Read out is permitted only when store 13 is empty. Transmit mode.-When switched to this mode, the terminal can transmit only after reception of a transmission-requesting polling signal from the distant station. The polling signal passes via units 21, 19 to store 17. Each character received in store 17 is checked to determine whether it is one forming part of a polling signal. If a sequence of characters forming the polling signal is received an affirmative response signal is placed in store 17 and transmitted via 19, 21. The data in buffer 15 is now read out to store 17 and transmitted. Receive mode.-The terminal can receive data only after reception of a reception-requesting polling signal from the distant station. The polling signal is detected, and a response generated, in the same way as described under " Transmit mode ". The distant station then transmits and the terminal receives the data via units 21, 19. Store 17 passes each character to store 13. If the data is low speed it is passed in parallel-bit form direct to the printer, but if it is high speed, store 13 is read out serially to buffer 15 and from thence, at the end of the message or when the buffer is full, to store 13 and printer 11. If the buffer fills, a signal indicating this is sent to the distant station to stop it transmitting. The remainder of the message can then not be sent until the buffer is empty and the distant station has again polled the terminal.
