Title: Improvements in or relating to coin controlled vending machines adapted to give change
IPC: G07F5/24
Filed: 1938-08-06
Abstract: 517,972. Change-giving apparatus. BRECKNELL, MUNRO & ROGERS (1928), Ltd., and DOLMAN, H. J. Aug. 6, 1938, No. ' 23256. [Class 27] In change-giving vending apparatus means is provided to keep the change coin reservoir adequately filled. Fig. 1 shows a reservoir 4 in which change coins are stored in pile formation, a pusher 50 being automatically operated to eject coins 5 as change into a tray 7. When the reservoir 4 becomes nearly empty, an endless conveyer belt 11, furnished with claws 14, is moved to lift coins from a bulk container 9 and drop them into'the top'of the reservoir 4 by way of an inclined channel. When the correct purchase money is inserted a delivery shaft 3 is rotated to eject the article bought, and when change is required the shaft 3 is coupled in known manner to mechanism associated with the pusher 50. The means for actuating the conveyer belt 11 consists of a pawl 20 pressed by a spring 23 into engagement with a ratchet wheel 19 on the shaft 3, so as to couple a disc 18 carrying the pawl to a sprocket wheel over which passes the conveyer operating chain 17. In its rotation the pawl 20 strikes against a spring-lifted detent 27 pivoted at 29, and is not freed till the detent is drawn down by a solenoid 31 energized by the closing of contacts 32 controlled by -a feeler 35 swinging into the coin reservoir 4. A plurality of reservoirs 4 may be provided, each having its conveyer 11, and in a modification the conveyers may be driven by a separate motor, instead of from the shaft 3. The feeler 35 may be duplicated, the conveyer 11 being started only when the lower feeler closes its contacts, and being stopped only when the upper feeler is moved by the accumulated pile of coins to opens its contacts.

Title: Manufacture of arylamino-aminoalkyl-compounds
IPC: C09B1/42
Filed: 1953-08-24
Abstract: In a process for the manufacture of arylamino-aminoalkyl compounds a halogen-aryl compound free from nitro groups is reacted with an aliphatic amine containing two primary amino groups and the resulting arylaminoaminoalkyl compound is isolated.  As aliphatic amines (which may contain a bridge member such as -NH-) there are mentioned ethylene diamine, 1:4- or 1:3-butylene diamine, 1:6-hexamethylene diamine and di-(b -aminoethyl)-amine.  Halogen-aryl compounds specified are chloro-benzene or bromo-naphthalene, which may contain other substituents such as sulphonic acid, carboxylic, carbonyl or ester groups.  With such compounds reaction under pressure, or in the presence of a copper-containing catalyst is necessary. a -Halogen anthraquinones react more easily, suitably at temperatures below 50 DEG  C.  The products form salts, and dissolve in dilute acetic acid. In examples: (1) chlorobenzene, ethylene diamine and sodium hydroxide solution are heated at 240-250 DEG  C. to form o -aminoethylaminobenzene.  The reaction can also be effected at lower temperature in the presence of copper powder. The product forms a nitroso compound with nitrous acid.  In a generally similar manner there are prepared (2) 1-(b -aminoethylamino) - naphthalene; (3) 1 - (b  - aminoethylamino) - naphthalene - 4 - sulphonic acid; (7) 1 - (aminoethylaminoethylamino) - naphthalene-4 - sulphonic acid; (8) 1 - (o  - amino - ethylamino) - benzene - 2 - carboxylic acid; (9) 1 - (b - aminoethylamino) - benzene - 4 - sulphonic acid.  In Example (4) 1-(b -aminoethylamino)-anthraquinone is obtained by reacting 1-chloranthraquinone with ethylene diamine at up to 40 DEG  C. Similarly prepared are (5) 1:5-di-(b -aminoethylamino)-anthraquinone; and (6) 1-(o  - aminoethylamino) - 4 - chloranthraquinone.  The products are suitable as intermediates and dyestuffs (see Group IV (c)).ALSO:In a process for the manufacture of arylamino - aminoalkyl compounds a halogen-aryl compound free from nitro groups is reacted with an aliphatic amine containing two primary amino groups.  The products are useful as coupling components and, when anthraquinone derivatives, are suitable for dyeing cellulose acetate silk or as dyestuff intermediates.  Sulphonic acid, carboxylic acid, carbonyl and hydroxyl groups may be present in the halo-aryl compounds.  In examples (4) 1-(b  - aminoethylamino) - anthraquinone is prepared by reacting 1 - chloranthraquinone with ethylene diamine at 40 DEG C. Similarly prepared are (5) 1 : 5 - di- (b  - aminoethylamino) - anthraquinon and (6) 1 - (o  - aminoethyl - amino) - 4 - chloranthraquinone.  Other examples describe the preparation of (1) o - aminoethylaminobenzene, (2) 1- (b -aminoethylamino) - naphthalene, (3) 1 - b  - aminoethylamino) - naphthalene - 4 - sulphonic acid and (7) 1 - (aminoethylaminoethylamino) - naphthalene - 4 - sulphonic acid, which couple with diazotized p - nitraniline to give dyestuffs, and (9) of 1 - (b  - aminoethylamino) - benzene o  - sulphonic acid which also couples with diazo compounds.

Title: Information storage system employing optical entry and removal of information
IPC: G02F1/03
Filed: 1971-04-19
Abstract: 1339959 Uses of photochromism RCA CORPORATION 19 April 1971 [8 June 1970] 23420/71 Heading C4S [Also in Divisions H3-H5] An electro-optical data storage device comprises a sheet of material in which an electric field is set up by incident optical radiation, the field influencing the refractive index of the sheet or of an associated sheet. Fig. 1 shows a laser 14 whose output is split into a reference component 24 and an object beam 22 on which information is impressed. On recombination at the storage device 12 a hologram light pattern is formed, and this sets up the electric field by a process of charge separation. The field charges the refractive index of the device, and thus the stored hologram may be read out by reconstructing the information with another laser beam, not necessarily of the same wavelength. Materials.-Where one sheet is used as both the field generator and the electro-optic read out material, it may be made of strontium titanate, calcium titanate or barium sodium niobate, all doped with Fe-Mo. Where separate sheets are used, the electro-o tic material may be lithium niobate, strontium barium niobate or strontium titanate; the field generating material used would then be either a photochromic material such as rare earth doped calcium fluoride or a non-photochromic material having impurity centres such as strontium titanate doped with Fe or Mo, undoped lithium niobate, or strontium barium niobate. The exposure time required for setting up the field with laser light of 4880  is several minutes, the mechanism probably involving diffusion of electrons from areas of high light intensity where they are generated to areas of low intensity. The readout laser wavelength may be chosen to disturb the stored field least. Reference has been directed by the Comptroller to Specification 1,219,473.

Abstract: 1437269 Sonar sustems; pulse selecting circuits FRANCE ARMED FORCES MINISTER OF 18 May 1973 [18 May 1972] 23931/73 Headings H4D and H3P Apparatus for monitoring pulses received in respective operating cycles of the apparatus includes a signal distribution arrangement for applying the pulses to one input of a coincidence detector and via a delay to trigger a time-window defining circuit whose output is applied to a second input of the coincidence detector. The predetermined time-window duration is greater than the pulse width but less than the operating cycle duration. The coincidence detector will respond to the occurrence of one pulse within the time-window triggered by the preceding pulse. The Fig. 4 embodiment may be used as an add-on echo discriminator unit for the active sonar of a first vessel (the firer) seeking a second vessel (the target). If B is the pulse repetition period (p.r.p.) then second and third p.r.ps should yield echoes E 2 , E 3  at times B and 2B after a first target echo E 1  if there is no relative radial velocity between firer and target. However, if there is radial velocity the second and third echoes will need to be looked for at times B#, 2B2#, respectively after the first, where # represents the maximum expected echo shift between consecutive p.r.ps. To avoid the minus sign in establishing search timewindows the first echo is delayed at 10, 11 by 2B and retained at 15, 18 for a duration 4#, the second echo is delayed at 10 by B+# and retained at 14, 17 for a duration 2#, and the third echo is delayed at 12 by 2#. The delayed third echo from 12 is checked at 16 for coincidence with the two retained echoes from 17, 18. Delay units 10, 11, 12 and 13 are shift registers, the echoes to be delayed being in the form of digital signals. The echo retaining circuits comprise shift registers 14, 15 with their individual stage outputs OR-gated at 17, 18: alternatively monostable circuits may be used. Synchronization of the clock pulses for shift registers 10, 11 with the sonar pulse transmission instant is described with reference to Fig. 5 (not shown). The addition of further logic circuits (Fig. 6, not shown) enables echocoincidence to be checked selectively in all three p.r.ps or in any two of three consecutive p.r.ps When the firer velocity is known it can be taken into account by modifying the delays introduced between echoes from the three p.r.ps.; in which case the term # can be reduced, to allow for target velocity only, so that there is less chance of spurious signal detection in the time-windows 2#, 4#. For sonars having several channels corresponding to different beam directions, the delays to be introduced between echoes from consecutive p.r.ps. will be a function of the firer vessel's speed and the cosine of the bearing angle of the beam. These delays may be introduced by use of further shift registers (40, 40<SP>1</SP>, 41, Fig. 7, not shown) whose clock pulse frequencies depend on the cosine and are derived from a master clock frequency related to the vessel's speed.
