Title: An automatic ticket gate
IPC: G07B15/00
Filed: 1968-01-30
Abstract: 1,208,664. Automatic ticket gate. TATEISI ELECTRONICS CO. 30 Jan., 1968 [6 Feb., 1967], No. 4780/68. Heading G4T. An automatic ticket gate adapted to test the validity of an inserted ticket is characterized by means preventing operation of the gate until the ticket is removed from the gate by the passenger. The ticket gate is substantially as described in Specification 1,198,718 together with the illustrated circuit arrangement. A validity signal A 2  sets flip-flop 31 and the set output is applied to AND gate 32. A signal A 1  generated when the ticket is removed from the ticket gate is applied to the second input of the AND gate 32, which fires to set flip-flop 34. Signal A 4  energizes a solenoid to withdraw a pawl unlocking the ticket gate. A switch operated by movement of the gate or, a photoelectric cell detecting movement of a passenger through the ticket gate, generates a signal A 3  to reset the flip-flop 34. NOT gate 35 resets the flip-flop 31 when signal A 1  disappears. In a modification the output from AND gate 32 is applied through a time delay to reset the flip-flop 34.

Title: An improved process for de-acidification of ammonia liquor by distillation
IPC: C01C1/10
Filed: 1951-02-28
Abstract: <PICT:0701986/III/1> In a process of freeing ammoniacal liquor from hydrogen sulphide and carbon dioxide, without appreciable loss of ammonia, by submitting part of the liquor to distillation and passing the vapours through a fractionating column which is supplied at or near the top with the remainder of the (cold) liquor, the vapours are conducted in a multiple loop - like path through the lower stages of the column and the mean temperature of the liquor in these lower stages is maintained approximately constant between 70 DEG  and 80 DEG C.  The column shown comprises a boiler A, de-acidifier B, and a water-scrubber C.  The middle and lower sections of de-acidifier B comprise five stages, separated by horizontal plates each containing five to seven bubble plates.  Part of the ammoniacal liquor (about one-third) is introduced at 20 DEG C. through inlet C into the top of the de-acidifier B.  The main bulk of the ammoniacal liquor is pre-heated and introduced through inlet a into boiler A, where it is heated, by indirect heating, to 95 DEG C. The vapours evolved are led through pipes b1 from stage 1 to stage 4 and from the latter, via stages 3 and 2, to stage 5; and a constant temperature between 70 DEG and 80 DEG C. is thereby maintained throughout stages 1 to 5.  The last traces of ammonia are removed from the vapours leaving the top of the de-acidifier by passing them through scrubber C, which is supplied with water through inlet d.  The scrubbing water is withdrawn through outlet f.  In an example a liquor containing 13.0 grm./litre of NH3, 6.8 grm./litre of H2S and 3.0 grm./litre of CO2 is treated by the process to give a deacidified liquor containing 12.9 grm./litre of NH3, 0.4 grm./litre of H2S and 0.2 grm./litre of CO2.

Title: Improvements in or relating to the production of a sugar-containing product
IPC: A23G3/42
Filed: 1937-02-22
Abstract: A product having a high milk sugar or other sugar content, e.g ice-cream, milk products for use after the manner of condensed milk or evaporated milk, certain candies and icings, is made of smooth consistency by producing in or adding to the mix minute insoluble particles, of a material other than sugar, in such quantities that the sugar, in excess of that which can be carried in solution, which crystallizes on the particles is of impalpable size.  The nuclei particles may be produced by partially precipitating casein from milk with rennet, alcohol, or a non-poisonous salt of a bi-valent metal. Alternatively, precipitated calcium carbonate may be added to the mix.  A process for making ice-cream is described in which rennet extract solution is added to the mix which is maintained at a temperature of 40 DEG  C. and thoroughly agitated.  The enzyme is added in quantity insufficient to cause complete coagulation.  The mix is preferably passed through a centrifugal pump, the enzyme solution being added slowly at the suction side.  The mix is subsequently heated to destroy the enzyme, and the mix may be desiccated to form a dry ice-cream mix.  Reference has been directed by the Comptroller to Specifications 189,026, [Class 28 (i)], and 442,892.
