Filed: 1966-12-13
Abstract: 1,174,239. Record player. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 13 Dec., 1966 [14 Dec., 1965; 17 Dec., 1965; 4 Nov., 1966], No. 55868/66. Heading G5R. [Also in Division G3] In a record player the turntable speed is automatically set in response to the position of an adapter 4 which is mounted coaxially with the centre spindle 2 of the turntable 3 and either remains in its upper position in the central aperture of a 45 r.p.m. record or is depressed against the action of spring 8 by a 33 r.p.m. record mounted on the spindle 2. The adapter rotates with the turntable and has secured thereto a horizontally extending pin 12 which can engage, in the upper and lower positions of the adapter, against abutments 16 and 17, respectively, on a plate 14 which is pivotally mounted 13 on the base plate 1 of the player. With a 45 r.p.m. record on the turntable, the adapter is in its upper position and the pin 12 moves the plate 14 to the broken line position, Fig. 3, in which an inclined portion 19 of the plate depresses a plunger 27 against the action of spring 29, Fig. 7. The plunger movement lowers an idler wheel 21, which drives the turntable, into contact with the larger diameter portion of drive spindle 23. On changing to a 33 r.p.m. record the adapter is depressed and the pin 12 which now engages the abutment 17 moves the plate 14 to the full line position, Fig. 3. The plunger is now released and the restoring action of spring 29 moves the idler to the smaller diameter portion of the drive pulley. In a second embodiment a pin-actuated plate engages a switch which electronically controls the drive motor speed directly.

Title: Circuit interrupter comprising electromagnetic opening means
IPC: H01H77/10
Filed: 1973-12-03
Abstract: 1412705 Overload circuit breaker WESTINGHOUSE ELECTRIC CORP 3 Dec 1973 [1 Dec 1972] 55909/73 Heading H1N A circuit interrupter has at least one pole unit in which contact separation is achieved by locating a contact arm in the entrance of a slot in a magnetic drive unit, comprising a core of magnetic material, in such a way that a predetermined overload current passing through the contact arm produces a flux in the magnetic core which causes the contact arm to be driven into the slot, thus separating the contacts. A three-pole circuit breaker comprises two series-connected units, the first being a storedenergy type circuit breaker 7 which is the subject-matter of Specification 1,263,819. This breaker trips at a first level of overload current by action of a bimetallic strip 51 and at a second level of overload by magnetic attraction of an armature 55, movement of either of these causing release of the latching mechanism 21. The second unit is the magnetic-drive interrupter of the invention 9, comprising three identical pole units 77 in each of which the magnetic-drive consists of a laminated U-shaped core 133 with a slot 137 the inner end of which is tapered so that a contact arm 93, lying in the mouth of the slot, can pivot into it when attracted by the magnetic flux (indicated by the arrowed circulation lies in Fig. 3) which results from current flowing through the contact arm. The contact arm 93 carries a moving contact 91 co-operating with fixed contact 83; it is mounted on a pivot 95 and has a latch extension 97 which engages in a latch 99 when the contact arm is in the fully open position against the abutment 146. The attractive force of the magnetic drive is resisted by a spring 101 which is overcome when the overload current reaches a third predetermined value higher than either of those at which operation of the thermal or magnetic actuating devices of the series circuit-breaker 7 is initiated. Arcing plates 145 and a re-set button 111 are provided. In a modification (Figs. 4 and 5, not shown) the fixed contact is replaced by a second moving contact carried on a second contact arm disposed in the mouth of a second magnetic-drive unit the two assemblies being in mirror-image arrangement and the two contact arms being linked by gearing at their pivots to ensure simultaneous operation. In a further modification (Figs. 6 and 7, not shown) the slot in the magnetic core is widened at its inner end to become T-shaped and the flexible conductor between the incoming terminal and the contact arm is wound around the yoke portion of the core, the turns being accommodated in the widened portion of the slot.

Abstract: 1,211,266. Carding tobacco. M. L. STRYDOM. 16 Dec., 1968 [18 Dec., 1967; 22 May, 1968], No. 59768/68. Heading A2C. Tobacco cut-rag is carded in a method wherein the cut-rag falls freely in countercurrent to a rising stream of air, the velocity of the air stream decreasing constantly towards the top of the path of fall, and wherein the air stream follows a path in which eddy currents are created on either side of the path of fall of the cut-rag. An apparatus for carrying out the above method comprises a vertical conduit which has a cross-sectional area which increases towards the top, a central clear zone for free fall and pockets to either side of this zone in which eddy currents may be created. A suitable apparatus is shown in Fig 1, wherein cut-rag enters the conduit through inlet 16 falls through the clear zone 12, passing an upwardly rising stream of air. The air stream is in the form of eddy currents which are formed by the zig-zag shape of the walls 10, 11. Treated cut-rag is removed via shoot 13 and extractor belt 14. The apparatus also includes means (Figs. 2 and 3, not shown) for delivering the cut-rag to inlet 16 at a constant mass rate. This means comprises a conveyer belt system which passes between plates 26 enabling the dielectric constant of the cut-rag to be determined. The speed of the belt is adjusted so that the average density of the material passing between these plates is constant at a predetermined value. Owing to a possible time lag in such control means, the cut-rag from the plates is delivered to an apron 28 provided with angled lip 29 which further enhances delivery of cut-rag at a constant mass rate.

As described, the system is used as a fire alarm, a number of units 20 being coupled to a common unit 10. Presence of a fire near senser 32 will fire SCR 1  to short lines l 1 , l 2  thus energizing alarm relay 4 which locks in over contacts 4a. Capacitor C4 discharges through "set" coil Rp of a latching relay to close contacts 26a, thus connecting relay coil 24 across lines l 1 , l 2 . When it is required to actuate relay 24, switch K1 is closed to energize an oscillator 6 which pulses relay 8. Contacts 8a, 8b, 8c now apply a pulse signal to lines l 1 , l 2  which operates relay 24, the relay being made slow-to-release so that it does not drop out between pulses. When it is required to release relay 24 switch K3 is closed to apply a long pulse to lines l 1 , l 2 . This pulse will fire a SCR2 and energize the "reset" coil R s  of the latching relay, thus opening contacts 26a. Relay 24 may energize a lamp, or may control a smoke extractor or fire doors.
