Title: Salivation testing devices
IPC: A61B10/00
Filed: 1957-03-07
Abstract: 855,916. Saliva detection. SCHWERIN, P. March 7, 1957 [March 29,1956; Jan. 14,1957], No. 7628/57. Class 97(3) [Also in Group VI] A device for use in testing salivation response to a stimulus comprises a body 10 the surface of which is moisture resistant except for a small portion 22a, the body comprising a plurality of layers of absorptive sheet material containing a non-toxic, water-soluble dye which colours when moistened by saliva. A length of gauze is dusted with powder consisting of can starch or white wheat flour and a pure food dye and is rolled up to form a pad 10. The pad 10 is given a coating of latex cement, a portion 22a being left uncovered, and is mounted on a handle 14. The pad is inserted in the mouth with the uncovered portion facing downwardly. Saliva entering the uncovered portion causes the dye to colour so that, when the pad is unrolled, a number of dyed areas are visible along the length of the gauze, the number of dyed areas giving an indication of the depth of penetration and the amount of saliva secreted. The pad may be made from a folded length of gauze or separate gauze layers. The depth of penetration of saliva in the pad may also be measured by placing the pad on a conducting plate (not shown) connected by a battery and a galvanometer with a probe, the probe being projected into the pad until the circuit is completed by the absorbed saliva. The number of dyed areas produced in a rolled length of gauze may be counted by unrolling the gauze and passing it between conducting rollers (not shown) in series with a galvanometer and a battery, the number of deflections of the galvanometer pointer indicating the number of dyed areas.

Title: Character recognition apparatus
IPC: G06V10/88
Filed: 1966-02-23
Abstract: 1,121,022. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 23 Feb., 1966 [1 March, 1965], No. 7903/66. Heading G4R. In character recognition apparatus, a reference character is synthesized line by line on display means and compared with the character to be identified, synthesis being stopped as soon as non-correspondence between a displayed line and the character to be identified is detected. Referring to Fig. 3 (not shown), the count in a character counter (20) is decoded (21) and together with the count of a stroke counter (25) causes an end point generator (22) to produce 8 bits for a stroke required for building up the character specified by the character counter (20) on a cathode-ray tube (14). One bit specifies if the stroke is to be blank, one if it is the last stroke of the character, and the horizontal and vertical deflections to get to the stroke end-point are specified by three bits each. A photomultiplier (15) receives light from the C.R.T. (14) screen via a film (10) holding the character to be identified. Eight bits are set into a register (32) from the photomultiplier (15) for each stroke and tested (37) to see if all are " one " or not. All ones indicates the character being built up corresponds so far to that on the film (10) and if the stroke is the last stroke of the oharacter, the character counter (20) reading is gated out (56) to identify the character on the film (10), if not the stroke counter (25) is stepped to display the next stroke. On the other hand, if the stroke is not all ones, the character counter (20) is stepped to try the next standard character. If a stroke is blank, the latter stepping is inhibited and the stroke counter (25) is stepped even though the all ones signal is absent.

IPC: C08F20/64
Filed: 1955-03-18
Abstract: Polymeric acids are prepared by heating polyunsaturated fatty acids corresponding to natural fat acids, at least one of which contains conjugated double bonds, in the absence of added water in a closed vessel at a polymerization temperature and under the pressure autogenously so generated.  In a modification, there is used as starting material a C18 hydroxy fatty acid or derivative thereof, which forms octadecadienoic acids consisting partly of the conjugated isomer at the said polymerizing temperature.  The polymerization may be effected at 300 DEG  to 350 DEG  C.  Polymerization catalysts such as finely-divided metals and anthraquinone may be present.  In examples: (1) distilled dehydrated castor oil fatty acids; (2) polyricinoleic acid obtained by Twitchell-splitting of castor oil; and (3) castor oil fatty acids are heated in an autoclave at 330-350 DEG  C. for 1-2 hours.  In a comparative experiment, distilled dehydrated castor oil acids are heated in an open vessel in a nitrogen atmosphere at 330 DEG  C., yielding a product having a lower acid value than that of (1).ALSO:Polymeric fatty acids are prepared by heating polyunsaturated fatty acids corresponding to natural fat acids, at least one of which contains conjugated double bonds, in the absence of added water in a closed vessel at a polymerization temperature and under the autogenous pressure so generated.

Abstract: 746,318. Cleaning teat cups. EMGARD. A. P.G. March 19, 1954 [March 20, 1953; July 18, 1953], No. 8085/54. Class 138(1) [Also in Group XXVIII] In a device for washing parts of a milking machine. such as the milk collectors 28. 29, Fig. 1, and the tubes and teat cups 30 attached thereto, wherein two pails 15, 16 which are closed by lids 18, 19, are connected by pipes 26, 27, contain a cleaning liquid and are in turn subject to a vacuum whereby the liquid flows from one pail to the other and back again and the pails are raised and lowered, meanwhile passing through the parts to be cleaned, the pails are attached to a metal band rope or chain 17 passing over a roller or rollers 7 which effect the change over of the air streams. A pipe 13 from each pail fits in a hole 10, Fig. 2, in each roller 7, and as the roller oscillates the hole 10 communicates alternately with a suction pipe 4 and an outlet 5 to the atmosphere; a ball valve 12 closes the tube 4 when the hole is opposite the outlet. If a single roller 7 is used, two sets of holes &c. are provided. Each roller bears against a stationary beam 2, the surfaces in contact being wide to prevent undesirable rocking of the roller. To limit movement of the rollers, each carries pegs 20, 21 to engage stops 22, 23, and to ensure that change over of liquid does not occur until most has been transferred, a braking device consisting of a spring-loaded ball 35 acts on a plate 32 which is fixed to the band 17 and slides in guides 34. Alternative braking-means comprise spring-supports for the pails, chains fixed to the band, and tubs containing liquid into which the pails dip. A teat cup may be joined to a pipe by a nipple 117, Fig. 6, having a conical opening to receive the cup, a restriction 115 to prevent the cup from passing through, and a tapered end 118 with a hole 119 to receive the pipe. Where two teat cups are connected by a nipple each end has a conical opening, (Fig. 5, not shown), Fig. 7 shows an arrangement for holding a set of nipples 123 and teat cups 101a. The nipples are held by clamps 122 on the ends of radial arms 120 extending from a hub mounted on a post 130, and the teat cups are pressed towards the nipples by forks 127 on the ends of similar arms 128. To prevent collapse of the teat cups due to the vacuum, connections are provided from the suction pipe 4 to separate compartments in a box 105, Fig. 3, under the milk collector 104, each compartment being connected by a tube 109 to a pulsator connection 110 on a teat cup cover 101.

Title: Glass pressing machine with a ram moved by pressure medium
IPC: C03B11/16
Filed: 1960-03-08
Abstract: 921,659. Glass pressing apparatus. A. E. RADINGER, H. C. RADINGER, and R. PILGRAM, [trading as H. PUTSCH & CO.]. March 8, 1960 [March 14, 1959], No. 8091/60. Class 56. The apparatus includes a press ram arranged to be moved towards and away from a mould by fluid pressure and a pressure-operated device for applying to the mould a closing collar slidably mounted on the press ram, a control valve being provided by which pressure on the closing collar can be maintained whilst that from the ram is released so that the ram can remain in position without applied pressure until the pressed glass is set. In the form shown, the glass is pressed between a die 35 and a plunger 37 carried on a ram 31. The ram carries pistons 19, 27 movable in stationary cylinders 18, 26 and also a piston 30 in a cylinder 29 which is slidable on the ram and to which are attached the supports 33 for the ring 34 which closes the top of the mould. Fluid pressure from a main 12 is applied through reducing valves 13, 20 to reservoirs 14, 21 and also to a conduit 44 and thence to valves 2, 3, 4 operated in sequence by a timing device 1. Operation of the valve 2 applies pressure to a conduit 11 to move valves 6, 8, 10 to positions shown. The valve 6 applies pressure above the piston 19 from the reservoir 14, through the conduit 16, to move the ram downwards. The valve 8 applies pressure above the piston 27 from the reservoir 21 equal to that applied continuously below the piston 30 from the same source. After a time sufficient to complete the moulding operation, the valve 3 applies pressure to a conduit 40 to move the valve 6 to the right to close the conduit 16 and vent the space above the piston 19 to the atmosphere. The pressures applied above the piston 27 and below the piston 30 being equal, the plunger 37 is held in contact with the glass only by the weight of the ram while the glass hardens and until the valve 4 operates to apply pressure to the conduit 42 to move the valve 8 to the right and the valve 9 to the left to vent the space above the piston 27 to the atmosphere and apply pressure from the conduit 44 through conduits 45 to below the pistons 19, 27 to lift the ram to a position where the cycle can recommence.
