Abstract: 1,231,521. Cyanoacetic acid preparation. CHRIS-CRAFT INDUSTRIES Inc. 30 April, 1969 [5 Aug., 1968], No. 22062/69. Heading C2C. In a process for the production of cyanoacetic acid, in which an aqueous solution of chloroacetic acid is neutralized with sodium carbonate to form sodium chloroacetate which in turn is reacted in a nucleophilic substitution with an alkali metal cyanide and the resultant cyanoacetate is then acidified to form an aqueous reaction mixture comprising cyanoacetic acid and the respective salts formed in such reaction sequence, improvements are made which comprise conducting the nucleophilic substitution reaction in the presence of a 3-12 C alkanol and at a temperature in excess of 80‹ C. to accelerate the reaction while substantially precluding undesirable side reactions, thereby increasing the yield of the cyanoacetate and decreasing the tendency of the reaction to form colour bodies, and extracting the acidified, aqueous reaction mixture with an alkanol which contains from not less than 3 to 12 carbon atoms and which is substantially insoluble in saturated brine, using the aqueous reaction mixture in such a manner that the amount of salts in such reaction mixture substantially saturate the amount of water present, thereby permitting substantially all of the cyanoacetic acid to be extracted by the alkanol. The neutralization may be carried out by using less than the stoichiometric amount of Na 2 CO 3  to achieve a pH of 4-5 and removing substantially all the residual CO 2  from the partially neutralized mixture under vacuum, and then completing the neutralization with NaOH before using the CICOONa in the nucleophilic substitution. The cyanoacetic acid may be esterified or converted into its amide by conventional procedures.

Apparatus for distributing objects, such as bars of chocolate, to wrapping machines (not shown), comprises a main endless conveyer 1 having sections 1b, 1c ... pivotable about axes of rollers 4b<SP>1</SP> by piston-cylinder means 6. The upstream ends of the sections 1b, 1c are each connected to one edge of a secondary conveyer 3b, 3c pivotal about its longitudinal axis 5b, 5c. The secondary conveyers have stop-bars 11b, 11c along the other edge. Assuming the apparatus to be as in Fig. 1 and all the conveyers to be driven, the presence of a row of objects on the main conveyer and the absence of any objects on the conveyer 3b will cause conveyer section 1b and conveyer 3b to be moved to the positions shown in Fig. 2. Conveyer 3b is stopped, the objects are transferred on to the conveyer 3b which is then restarted as it and the conveyer section 1b are restored to their Fig. 1 positions. If objects are still on the conveyer 3b when a further row of objects on the section 1b approaches the conveyer 3b the cylinder 6 is not energized and the objects pass on to the section 1b for transfer to the conveyer 3c. The apparatus is controlled by photo-cells which detect the objects at various stages of their travel.

Abstract: 1317306 Storing articles LVP ELECTRONIC DEVELOPMENT CO Ltd 25 June 1971 [7 July 1970] 32999/70 Heading B8E [Also in Division G4] A storage arrangement, particularly intended for use with semi-automatic dry cleaning and cloakroom facilities, comprises a series of storage locations, e.g. 50, 52, a conveyer member 54 which may be selectively moved to a series of positions, each position corresponding to a respective storage location, and at least two series of indications e.g. 198, 298 that are sensed by means 60, 62 on the conveyer member 54 to identify each said position, the two series of indications being used to provide a check between the series. In the particular embodiment of dry cleaning system shown when the customer deposits coinage conveyer 54 is operated to pick up an empty garment bag 82 and deliver it through an access door (30), (32) (Fig. 4, not shown), each bag carrying a detachable identification tag which is removed and kept by the customer. After placing the clothes in the bag, which also includes a tag for subsequent identification of the clothes, the conveyer 54 carries the bag to a staff access opening 16, the clothes being removed, cleaned and subsequently placed at the particular storage location corresponding to the associated identification tag. On collection the customer inserts the detachable identification tag into a reader 76 which is coupled via electric control means 64 to the conveyer 54 and causes the conveyer to move to the required position with the aid of the indications sensed by photo detectors 60, 62. The conveyer 54 is driven by fast and slow motors 70 and 72 and may be arranged either to slightly overshoot the required position under the control of the fast motor and then be returned slowly or, to approach the required position quickly and finally be advanced slowly. When the required position is identified transfer means are operated to effect transfer-of a garment bag from either the right or left series of storage locations to the conveyer, this choice either being determined either with the aid of the respective indications 198, 298 or by a control signal from the control means 64, and the selected bag is then delivered to the customer. Other applications of the storage arrangement are in "collection only" dry cleaning and laundry systems, automatic or semi-automatic (i.e., with an attendant for issuing and receiving identification tags) cloakrooms and article dispensing apparatus. When used in a cloakroom system the received clothes are tr nsferred directly from the pick-up point to a storage location, and in these systems and also article dispensing apparatus control of the conveyer for collection of particular clothes or articles may be by a manually selected code. The storage locations may be arranged in two or more tiers, with either a single conveyer member for all the tiers or a conveyer member for each respective tier. Specification 1,107,988 is referred to.
