Patent GB-1019090-A (GB)
Title: Tray clearance testing mechanism
Inventor: GECEWICZ NORBERT ANTHONY
IPC: G07D7/00
Filed: 1964-02-27
Abstract: 1,019,090. Photo-electric testing devices. AUTOMATIC CANTEEN CO. OF AMERICA. Feb. 27, 1964, No. 8253/64. Heading G1A. The invention relates to an arrangement for checking that a sheet of material is printed, or provided with other means modifying its transmissivity, in a required way. It is described with reference to means checking the transmissivity of a currency note at a plurality of positions to determine if it is authentic. According to the invention means are provided for positioning the sheet for testing, for removing the material from the test position if found acceptable, and for thereafter testing by a radiation responsive device that removal has been effected. Thus, in a machine giving change for a authentic note, the mechanism delivering the change may be prevented from operating until the note has passed from the test position. The circuit of such a change giving machine is shown in the figure. Presentation of a note in a slide to the test position, achieved by pressing in the slide, operates contacts 92, 94 and 96 if the note is correctly positioned and the slide right home. Closure of these contacts energizes the slide-lock relay 125 and starts motor 100 driving the rotary arms of a programme switch. Lights 117 and 119 are switched on and light passes through the note to groups of photo-cells 199a, 199b and 199c positioned under areas that should be white, green and black respectively. If more than a predetermined amount of light is received by any of the cell groups contacts 71, 81 and/or 86 close to indicate imperfect or counterfeit currency and relay 170 is energized to prevent the giving of change and to force the slide. If the result of this test is satisfactory a further test is programmed to ensure that adequate light passes the light and dark areas of the note, a change in cell circuits and operating conditions being effected by relays. If the note is satisfactory in this test, contacts 71 and 86 both close to energize relays 150 and 160. Operation of these relays prepares for the energization of motor 145 in the next step in the programme. The motor operates means removing the note from the slide and photo-cells 199c are used in a circuit including relays 80 and 140 to determine that the note has in fact been cleared. When relay 140 operates pay-out motor 14 is energized to move finger 14<SP>1</SP> to dispense the coin change into a shoot. At the end of the cycle the machine resets. Provision is made to prevent operation if the machine is empty or a coin jams in the payout mechanism.

Title: Improvements in and relating to the protection of multi-speed electric motors
IPC: H02H7/085
Filed: 1955-03-24
Abstract: 764,758. Control of A.C. motors. GENERAL ELECTRIC CO. March 24, 1955 [March 24, 1954], No. 8618/55. Class 38(3) A multi-speed squirrel cage motor having a starting winding 4 as well as highspeed and low-speed running windings 5, 6, is protected against overload when operating at either speed by means of thermally-operated units 34, 39, which are associated with the windings 5, 6, respectively. For high-speed operation, switch arm 20 is engaged with terminal 22 so that the starting winding is energized through centrifugally-operated switch arm 16 and capacitor 29, and the winding 5 is connected in parallel with the winding 4. The motor circuit is completed through the heater coil 35 and bimetallic element 36 of the unit 34, and the bimetallic element 38 of the unit 39, the heater coil 45 of the second unit being omitted from the circuit. The protection of the motor thus depends principally upon the coil 35 which is chosen in view of the properties of the winding 5 with which it is associated. At a predetermined speed, the contact arm 16 moves to disconnect the starting winding 4. The switch arm 20 is moved to engage the terminal 23 for low-speed operation; and, as before, the windings 4 and 5 are energized. When the motor reaches fullspeed, however, the contact arm 16 engages contact 43 to de-energize the windings 4, 5, and to energize winding 6 through heater coil 45 and bimetallic element 38. In a modified arrangement, a single protective unit is provided with only-one bimetallic element and two heating coils connected respectively in series with the motor windings 5 and 6 (Fig. 2, not shown).

Title: Improvements in and relating to the preparation of photographic emulsions
IPC: G03C1/015
Filed: 1936-03-25
Abstract: 472,639. Photographic silver halide emulsions. CLAUS, B. March 25, 1936, No. 8939. Convention date, April 5, 1935. [Class 98 (ii)] Emulsions of medium grain and high sensitivity are prepared by forming a precipitate of silver halide, especially silver bromide, freeing this from the reaction products by decantation emulsifying it in a binder such as aqueous gelatin solution and allowing it to ripen therein and then adding to the emulsion so formed further silver halide which may be emulsified in a binding medium, and allowing the mixture to ripen further at a suitable temperature with if desired the addition of a ripening agent such as ammonia. In one example, solutions of potassium bromide containing some potassium iodide, and of silver nitrate are mixed and the precipitate washed. Part of this precipitate is then emulsified in gelatin with addition of ammonia and the mixture heated. The rest of the precipitate is then gradually added and sufficient gelatin to produce the desired content thereof is added. In another example, the precipitate formed as before is emulsified in gelatin and divided into two parts, to one of which ammonia is added and the mixture heated. The remainder is then gradually added, if necessary with the addition of ammonia, and finally more gelatin is added. The Specification as open to inspection under Sect. 91 includes also a further example in which separate solutions of silver nitrate, and of potassium bromide, potassium iodide, and gelatin are prepared, the former being stirred into the latter and the precipitate allowed to settle, the supernatent liquid being removed by decantation. The precipitate is then washed and divided into two parts, one of which is added to a solution of gelatin and ammonia. This is kept for 20 minutes at 50 C. and the other half then added together with more ammonia, the resulting mixture being stirred for 30 minutes at 50 C. and the remaining ammonia neutralized with citric acid. Reference is made to the use of citric acid for this purpose in examples 1 and 2. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,240,099. Apparatus for quenching melt spun filaments. ALLIED CHEMICAL CORP. 24 Feb., 1970 [7 March, 1969], No. 8944/70. Heading B5B. As shown in Fig. 1, an apparatus for quenching melt extruded filaments of a synthetic organic polymeric thermoplastic material comprises an entry chamber 1 for a cooling gas (preferably air) formed by outer cylindrical neoprene rubber bellows 2 which surrounds an inner cylindrical neoprene rubber bellows 3 in a concentric manner thereby forming a gas entry chamber of annular cross-section. Cooling gas entering the chamber 1 is passed through filter felt 4 and then through perforations in the wall of a perforated metal cylinder 5 into a porous, multi-cellular, polymeric foam diffuser 6. The cooling gas is diffused in diffuser 6 and enters quench chamber 7 as a substantially non- turbulent stream before quenching filaments 8 extruded from spinneret assembly. The cooling gas then passes downward through quench chamber 7 into and through the cooling stack 10 and is discharged therefrom. The filaments emerging from the stack 10 are drawn and collected in take-up means 11. Spinneret 9 is surrounded by a cylindrical wall 12 which surrounds and encloses the filaments which are extruded from spinneret 9. The rubber bellows 2 is connected to the inner flange 13 of the wall 12 and the metal cylinder 5 is connected to the inner flange 14 of the wall 12. The bottom of the cylinder 5 is connected to the outer flange 15 at the top of the stack 10 which serves as a further cooling chamber for the quenched filaments. The inner bellows 3 is connected to the upper part of the stack 10. The filter felt 4, which may be of woven or non-woven felt material, is wrapped around the metal cylinder 5 and serves to provide a means for producing an additional pressure drop across the diffuser 6 and to filter dust from the cooling gas prior to its entry into the chamber 7. The diffuser 6 is held in place by a flange 17 at the bottom of the wall 12 and a flange 18 at the top of the stack 10. The diffuser 6 can be cut from porous bulk material or can be fabricated from slab stock. It may be preferably ¢ to 2 inches thick and have a length (generally parallel to the axis of the quenching chamber) of preferably 6 to 24 inches. The diffuser 6 has preferably 75 to 150 cells per linear inch and a cellular void volume of preferably 75 to 97% of its total volume. The bulk density of the polymeric foam of which the diffuser consists is preferably 1À4 to 6 lbs per cubic foot and the foam may be flexible or rigid. The preferred diffuser material is a polyurethane foam, but it may be a polyvinyl chloride or polyvinyl acetate foam, or a natural or synthetic foam rubber.
