Title: Improvements relating to self-starting synchronous motors
IPC: H02K21/14
Filed: 1948-02-27
Abstract: 642,477. A.C. motors. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Feb. 27, 1948, No. 6127. Convention date, June 11, 1946. [Class 35] In a shaded-pole self-starting synchronous motor having a permanently magnetic imbricated pole rotor and an imbricated pole stator energized by an A.C. fed coil, the reverse torque at starting is reduced or eliminated by displacing the shaded polepieces relatively to the unshaded poles by an angle of 120-150 degrees in the desired direction of rotation. Preferably this angle is equal to 180 degrees minus the angle of flux phase-shift in the shaded poles, this phase-shift being normally about 45 degrees. In one form, Fig. 1, the motor comprises a pair of stators and rotors. The double rotors comprise two pairs of toothed plates on each side of a permanent magnet, alternate teeth 10, 11 being bent across to co-operate with teeth 9, 12 extending directly from the magnet. The stators, of which one carries a shading ring 4, are secured side-byside in a casing 2a. Either the stators or rotors may be mutually displaced by an angle, e.g. 135 degrees, in accordance with the invention. A preferred form of motor is shown in Figs. 5 and 6 in which a single coil 18 energizes pole teeth bent out of side walls 13, 14. Shading rings 16, 17 are secured to the side walls and the unshaded poles 1, 3, 5 and 2, 4, 6 are bent so as to extend between the shading rings and present an edge to the imbricated permanently magnetic rotor 23. The shaded poles 7, 9, 11 and 8, 10, 12 are bent inside the rings so as to present a flat surface to the rotor. These shaded poles may approach close to, and some may be fixed at their ends to, the other side plate so as to increase the angle of flux displacement. For ease in carrying out their displacement, the shaded and unshaded poles are arranged in groups instead of alternating with each other as in the usual arrangement.

Title: Improvements in and relating to coin-controlled vending machines
IPC: G07F11/44
Filed: 1919-03-12
Abstract: 138,202. Alexander, A. E., (Millard's Gum Vending Corporation). March 12, 1919. Delivery of articles stored in bulk; coin action, mechanical-connexion.-An apparatus, suitable for vending articles such as chewing-gum in ball form, comprises a glass case a mounted on a base b and provided with a top c. The bottom b' of the case has a discharge opening d and a filling- opening d' close.d by a plate d<2>, articles discharged through the opening d being delivered through a shoot e to an opening e<1>. A rotatable member g is mounted centrally on the plate b<1> and has openings g<1> to receive the balls of gum one at a time and convey them beneath a baffle-plate g<2> and over the opening d. A coin shoot h<1> is mounted in a tubular member h rotatable in the member g, and has parallel walls which are partly cut away above the member g over diagonally opposite areas. The tube h is provided with a hand-hold i and is controlled by a spring k. The rotation of the tube is limited by the engagement of a lug j<1> thereon with shoulders c<3>, c<4> on a ring c<1> projecting from the top c of the casing. The rotatable member g has slots m, m<1>, n, n<1> therein, each having a short radial side and a long side, as shown in Fig. 2. The bottom plate b<1> has a circular spring o with side extensions o<1>, o<2>, as shown in Fig. 3. A coin inserted in the coin shoot falls to the bottom and takes a position such that it projects partly through the opening o and couples the coin shoot with the member g and permits rotation of the latter by the hand-hold i, the cut-away portions of the shoot confining this rotation to one sense only. On reaching the position in which the slots, say m, m', in which the coin is engaged, are alined with the slots o<1>, o<2>, an article is delivered, and, on release of the pressure on the hand-hold, the coin drops through the slots o<1>, o<2> into the money-box. Owing to the form of the slots, it will not be possible to obtain a second operation of the apparatus by one coin, however quickly the shoot is returned after delivery of an article. A slug of diameter such that it projects into the part of the shoot which is not cut away will prevent the shoot from turning back to its original position under the impulse of the spring. The delivery shoot for articles is formed with a projecting loop p to prevent operation of the apparatus by inserting the finger.

Patent GB-453051-A (GB)
Title: Process for producing coated discs for use in sound recording
IPC: B28B21/56
Filed: 1935-02-28
Abstract: A process for producing coated discs suitable for sound recording and matricing, comprises applying to a metal base very thin layers of varnish, thoroughly drying, and then applying further thin layers of varnish in which the actual sound grooves are to be formed, the separate layers or films being applied by spraying, by immersion, or by pouring the varnish upon the base while it is in rapid rotation. When spraying is adopted, a number of base discs may be rotatably mounted on a turntable or on an endless belt, and the spray nozzle may be moved radially of each disc, the flow of varnish being automatically controlled. Separate nozzles may supply varnish and diluent, and a suction nozzle may be provided to remove solvent vapour or foreign matter. The centre of each disc preferably receives no varnish, though a single protective coat may be applied after the central label has been positioned.  Drying devices may be incorporated in the varnishing machine, and the layers of varnish first applied may be ground or polished before the layers in which the sound grooves are to be formed are applied.  Suitable varnishes are those prepared from cellulose esters or artificial resins, and an alloy of lead and zinc may be used for the metal base, so that the latter may be free from internal stresses.  Reference has been directed by the Comptroller to Specifications 287,940 and 298,608, [both in Class 95].

Title: Improved apparatus and method for sensing records
IPC: G06K7/08
Filed: 1962-02-19
Abstract: 983,007. Sensing magnetic records. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 19, 1962 [March 17, 1961], No. 6333/62. Headings G4M and G4R. Information represented by magnetised areas on a record is sensed by inducing duplication of the magnetised areas upon a magnetisable surface of a transfer medium which is then magnetically sensed. Creases in a record cause the magnetised areas to become separated from a normal reading read and prevent proper reading. This is overcome by transferring a magnetic image of the record on to a drum 15 under the pressure of a second drum 13. The cheques 10 have characters printed in magnetic ink which are first magnetised by a head 12 fed with A.C. A magnetic transducer 16 fed with A.C. or D. C. makes a strong field normal to the drums at their point of contact. This transfers a magnetic pattern from the characters to the surface of drum 15 which is sensed at 17 to control a sorter or other statistical machine. In another form the cheque 10 is fed by being gripped between a pair of flexible belts, the magnetic characters on the exposed part of the cheque being transferred by being pressed between two spring loaded drums one of which has previously been magnetised with alternating current. In the form of Fig. 2 the data is recorded in magnetic strips 22 the magnetic pattern of which is transferred to drum 24 against which the card is pressed by rollers 23, 27. Photographic inserts 21 in the record are identified by the recorded data. Specification 854,449 is referred to.

Abstract: 685,185. Wrappers for magnetic tape rolls; boxes; roll holders. AUDIO DEVICES, Inc. March 16, 1951 [March 23, 1950], No. 6397/51. Classes 18 and 94(ii) Magnetic tape rolls are enclosed in a wrapper comprising two juxtaposed flaps hinged about an intermediate end wall, the first flap 24 (Fig. 7) having a slot extending from its front edge and the other flap having centrally disposed a raised hub 40 fitting within the hub 44 of the roll of tape. The wrapper is then enclosed in an outer carton. The hub 40 may be integrally secured to the flap 26 or rotatable thereon. The roll hub 44 has screws for securing a flange 120 or pair of flanges to the hub and aligning holes 64 for lugs on the flanges but flanges may be dispensed with for horizontally arranged reels and if used during recording and/or reproducing with vertical reels are removed before storage of a roll in its carton. Further, flanges are not supplied with the cartons, thus achieving economy. The roll hub also has slots 138 for receiving driving lugs 88 (Fig. 6) on a turntable over which the wrapper is used for placing the tape, and may then be removed as shown. The flap hub 40 and a turntable locating hub 80 are jointly of depth less than the thickness of the tape hub. Apertures 52, 54 adjacent the flap hub 40 allow manipulation of the tape reel. The flap 24 overlies at least in part the hub screw holes for the flanges to facilitate retaining the screws and coacting threaded sleeves while loose before screwing them together. The outer carton is a box open at the top but closed by the intermediate end wall of the flaps, and with finger slots for removing the wrapper. The carton base is a flap with tab centrally recessed clear of the tape.

Title: Apparatus for comparing the spectral reflectance of coloured surfaces
IPC: G01J3/51
Filed: 1973-02-09
Abstract: 1384501 Photo-electric detection systems LANDIS & GYR AG 9 Feb 1973 [17 Feb 1972] 6617/73 Heading G1A Apparatus for comparing the spectral reflectance of coloured surfaces includes an arrangement for making a plurality of measurements at the same point on a test specimen and a genuine article, each measurement covering a different narrow spectral range and involving sequentially detecting, with a single light sensitive detector, the light reflected off the same point of the genuine article and the test specimen, evaluating means being connected to the output of the detector and including a dividing circuit to form the quotient of the sequentially obtained signals during each measurement, and a circuit for determining the spread of the quotients over the plurality of measurements. As shown, light is directed sequentially on to a genuine article 9 and a test specimen 10 by means of a moving filter 4, which may move continuously or intermittently, having a mask 5 with apertures 6, and a pair of light guides 7, 8, the reflected light being directed to the detector 13 by light guides 11, 12. The dividing circuit 15 receives a synchronizing signal from a control circuit 18 which also synchronizes a memory circuit 17 connected to the output of the dividing circuit. The memory output is connected to a plurality of window-type comparators 25-29, each of which is associated with a predetermined range of output values of the memory, the comparator outputs being connected to counters 30-33, as shown. If any of the counters counts to a predetermined value, a 'yes' output is given via an OR gate 34. However, if none of the counters counts to a predetermined value, a 'no' output is given. The dividing circuit may be of the doubleintegration type or as described with reference to Fig.2 (not shown). The apparatus may be modified by replacing the moving filter with a rotating system having discrete individual filters, e.g. a drum with the filters on the curved surface and a light source inside. Also, instead of light guides, a mirror system may be used.
