Title: Improvements in or relating to nail or like fastener assorting mechanism
IPC: A43D71/00
Filed: 1933-02-10
Abstract: 414,731. Nailing. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICHARDS, A. E., PRATT, J. W., and JACKSON, H. A., Belgrave Road, Leicester. Feb. 10, 1933, No. 4099. Addition to 391,116. [Class 89 (iii).] Relates to a modification of the racewayclearing devices described in the parent Specification for nail-assorting mechanisms of the kind in which the raceway is given a lengthwise movement and a movement towards and away from a fixed raceway cover. The clearing device is described as applied to the nailing machine described in Specification 1494/93, [Class 89], when adapted for the insertion of Cutlan Bills by the provision of the nailseparating means described in Specification 303,780, [Class 89 (iii)], and the work-locating means described in Specification 312,956, [Class 89 (iii)]. A member 28 fixed to and moving with the raceway 36 has a groove 38 aligned with the raceway channel and lying above it. This groove is of a size to permit passage of the nail heads, but not to admit the shank of a misplaced nail extending lengthwise of the raceway. Thus, such a shank is prevented from entering, and jamming in, the groove of the fixed raceway cover 40 when the raceway is separated from the cover during its normal movements. A clearer for misplaced nails comprises a spring-pressed member 2 which is oscillated by an arm 14 and cam so that its nose moves lengthwise of the raceway in contact with the upper surface of the member 28 and with the raceway. Specification 209,824, [Class 89 (iii)], also is referred to.

Title: Improvements in or relating to the utilization of a gaseous conductor or discharge tube for controlling the operation of an electromagnetic device
IPC: H04Q1/32
Filed: 1935-02-08
Abstract: 431,630. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Anderson, L. T. ; 96, North 18th Street, East Orange, New Jersey, and Low, F. K.; 179, Columbia Heights, Brooklyn, New York, both in U.S.A.) Feb. 8, 1935, No. 4104. Convention date, Sept. 7, 1934. [Class 40 (iv)] [See also Group XL] An impulse receiving circuit comprises a gas discharge tube, a two-winding relay in the anode-cathode path and a condenser connected between the cathode and the relay so that for one condition of the impulsing circuit (make or break), the tube intermittently ionizes and de-ionizes, and the condenser charges and discharges through the relay windings in such a manner as to hold the relay operated. The circuit may be applied to the direct setting of selectors in automatic telephony, to setting register-controllers or for impulse repetition. As shown, the grid of the tube 104 is connected to the negative leg of a calling loop ; the cathode is a few volts less negative than the exchange battery voltage as determined by a potentiometer 106, 107 including the heater of the tube, anode potential being provided by the exchange battery. The junction of the two windings L, H of relay 110 is connected by condenser 111 to the cathode. Normally the grid potential is sufficiently negative to block the tube, but when the calling loop is completed, the negative bias decreases and condenser 111 discharges over the low resistance winding L and the tube to operate the relay 110. As the condenser discharges, the anode potential falls until the tube ceases to conduct and the condenser charges again over the high resistance winding H which holds the relay. The relay may have a short-circuited third winding, or other device to make it slow.

[Class 35.] Alternating-current induction machines; machines with two armatures; motors, controlling.-A slowspeed motor for gramophone &c. driving has a single rotor subjected to the action of two distinct stators acting respectively as the stator of an induction motor and the stator of a synchronous machine, the rotor being constituted by a two-part member, one part being a good electrical conductor and the other of paramagnetic material. The asynchronous stator 1 has a coil wound in the first and third slots and a second coil carrying a phase-displaced current in the second and fourth slots whereby a rotating field is produced. The rotor comprises an aluminium or other conducting disc 4 mounted on a ferro-magnetic disc 5 having teeth 6 co-operating with the synchronous stator 8. The teeth may be formed on the periphery of the disc in which case the stator 8 is disposed with the plane of its lamina. tions parallel to the plane of the rotor. The rotor mav be cylindrical so that one of the stators is outside and the other inside and the air-gaps are curved. In a modification, Fig. 3, the asychronous part of the rotor comprises a squirrel cage winding 10 located in slots in a toothed magnetic disc or cylinder 3, the teeth on opposite faces being staggered as shown. Both stators may be placed on one side of the rotor. The synchronous part of the motor acts to maintain constant the speed as described in Specification 342,427, but in order to avoid the necessity of short-circuiting the winding 9 on the stator 8 at starting, (the two stator windings being connected in series), the synchronous speed of the synchronous element, i.e. the working speed, is chosen higher than in the prior Specification, for example a slip of about 30 per cent is selected. Several stator units may act in the rotor.
