Title: Process for the allylation of organic compounds
Inventor: STEPHENSON ROBERT JAMES
IPC: C07C45/71
Filed: 1963-08-20
Abstract: The alkylation of organic compounds containing an active methylene or an active methine group in which the methylene or methine group is attached to two activating groups of the kind exemplified by cyano and carbonyl is effected by reaction of said organic compound w4th an allyl alcohol or an allyl ether. If an activating group is a carbonyl group it may be ketonic or aldehydic or form part of a carboxyl, ester or amide group.  Other specified activating groups are the nitro group and, in certain cases, an aromatic ring.  Preferred allyl alcohols are those of the general formula R1-CH = CH-CHR2-OH wherein R1 is a hydrogen atom or a substituted or unsubstituted hydrocarbon group and R2 is a hydrogen atom or an alkyl group or R1 and R2 together with the -CH = CH(OH)-CH- radical form an alicyclic ring, and preferred ethers are those derived from said alcohols.  The reaction, which is usually effected by heating the reactants, may be performed in the presence of a catalyst which can be an acid, including Lewis acids and acidic ion exchange resins, but is preferably an acid together with a salt of a metal that is capable of forming a complex compound with an olefin.  The products of the allylation are compounds wherein a hydrogen atom of the active methylene or methine group has been replaced by an allyl group of the allyl alcohol or ether.  In the only Example 3 allyl pentan-2-4-diol is prepared from acetyl acetone and diallylether in the presence of a sulphonated cross-linked polystyrene resin and cuprous chloride as catalyst.

IPC: G05B19/23
Filed: 1968-07-03
Abstract: 1,249,321. Positioning systems. SELECTRO-MICRO CO. Ltd. 8 Sept., 1969 [3 July, 1968, 12 July, 1968], Nos. 31671/68 and 33307/68. Heading G4H. In a film positioning unit the count in a counter 10 (Fig. 1) holding the datum position of the film is initially incremented by an amount representing the maximum count of an auxiliary counter 56, the count in the counter 10 which is incremented as the film moves then being compared with the required position represented by the data in store 18: At equality i.e. when a signal exists on lead 34, the film continues to move at a slow speed with the incremental pulses being fed to count down the auxiliary counter 56 until its count reaches zero when the film is at the required position. The direction of movement of the film is determined by the relative values of the datum and required positions. Register stages 70A, 70B, 70C, 70D (Fig. 2) control the pulsing of the counter 56, the movement of the film at high speed, the slowing down of the film at the equality output from the comparator and the stopping of the film when the counter 56 has been counted down to zero. The film may be returned to its original datum position by operating a switch D to alter the direction of movement of the film and to set a destination/datum store 94 to its " O " state. The system then operates as before except that the comparator equality signal is given on lead 36 and at equality of the datum and actual position register stage 70E is actuated to release the film cassette. The pulses as the film moves are derived from a photo-cell 5 sensing markers on the film, the counter being set to count either light to dark or dark to light transitions in accordance with the direction of movement. When a required position is keyed in contact A2 (Fig. 4 not shown) is closed to enable a shift register (208) so that as the keys are selectively operated to read in a four digit word four stages of the shift register are sequentially enabled to control a routing gate (204) connected to the destination store. When a datum position is keyed in, a shift register (210) is enabled so that the four digits are fed via a further routing gate (206) to the datum store and also under the control of sequential pulses on four leads (234, 236, 238, 240) to the counter 10.
