Title: Improvements relating to bobbin holders
IPC: B25B13/54
Filed: 1964-05-07
Abstract: 1,069,892. Supporting creel bobbins. R. K. WHITEHEAD AND R. K. WHITEHEAD, JUN. May 7, 1964 [Dec. 3, 1963], No. 19074/ 64. Heading D1J. A bobbin holder comprises a central body C slidably movable in a tubular member S, pawls 51, 52 for holding a bobbin and operatively connected to body C, and means for positioning the pawls, in response to movement of the bobbin relative to member S, alternatively in a position inside member S and in a bobbin engaging position outside member S. To release a bobbin B from the pawls the bobbin is pushed up the member S, thus pushing a sleeve and body C connected thereto by arms 32, 34 extending through slots in the member so that pawls 51, 52 are cammed inwards by edges 105 of the member. A camming ball 99, movable within a transverse groove 63 in the body C and within a channel 101 in one half 44 of member S, is thus caused to move up the right hand (Fig. 3) section of channel 101 and then falls into recess 107. In this position the pawls are held retracted and the old bobbin can be replaced by a new one which on pressing the sleeve upwards causes ball 99 to rise out of recess 107 thus allowing it to travel down the left hand section of channel 101 so that the pawls move outwardly to hold the bobbin. The bobbin holder is suspended from a creel rail.

Title: Timepiece
IPC: G04B19/253
Filed: 1973-04-19
Abstract: 1433038 Calendar timepieces CITIZEN WATCH CO Ltd 19 April 1973 [19 April 1972] 19089/73 Heading G3T A calendar timepiece has a date ring 29 and a day wheel 24, which are indexed by respective pawls 7, 8 mounted on a lever 4 which is biased by a spring 5 against a snail cam 3 which rotates once per day, means being provided which prevent double-indexing of the calendar indicators but which permit correction thereof by a member 40 at any time. In the embodiment shown, after indexing, further indexing is avoided by engagement of projections 7b, 8b with respective arms 28a, 26a which prevents further rotation of the pawls. Should member 40 be operated at this time, arms 28a, 26a flex to permit correction of the indicators. In the modification of Fig. 7, not shown, arm 28a is omitted and double-indexing of date ring 29 is prevented by a projection (4f) of lever 4 engaging with one of the date ring teeth. To permit correction, lever 4 is forced to rotate about pivot 30 upon operation of member 40. In an alternative modification, Fig. 10, a rigid member 41 normally prevents double-indexing of the day wheel. Movement of member 40, which may be a conventional winding stem, to a calendar-correcting position rotates member 41 out of engagement with projection 8b. In the embodiment of Fig. 11, (not shown) a further pawl (43) rotated by a projection (4g) of lever 4 prevents double-indexing of the day wheel. In a final embodiment Fig. 12 (not shown) day feed wheel 23 is mounted on a resilient arm (49); double-indexing of the day wheel is prevented by a fixed arm (28c) but operation of the correcting member 40 carries the arm (49) to flex, thus disengaging wheels 23, 24.

Title: Remote control receiver for central remote control installations utilising audio-frequency signals superimposed on the mains network
IPC: H02J13/00
Filed: 1957-06-21
Abstract: 820,345. Electric selective signalling systems. LANDIS & GYR A.G. June 21, 1957 [June 23, 1956], No. 19652/57. Class 40 (1). In an electric selective signalling system of the kind wherein a start pulse (transmitted over power lines as a superimposed audio frequency) causes the rotation for one cycle of a synchronously driven distributer at the receiver and is followed at a selected time in the cycle by an order pulse, the receiver is so constructed that unless the start pulse is of sufficient duration the distributer does not rotate through a complete cycle but returns to its normal position. In a first embodiment, Fig. 1, the start pulse energizes a relay (not shown) to cause a synchronous motor to drive a shaft W of the distributer. As the shaft rotates, in the direction indicated, a reset lever RH is pushed upwards by a lip on a reset cam R against the action of a spring RF. If the start pulse is of a sufficiently long duration the shaft W will rotate to such a position that the lip on the reset cam R clears the reset lever RH. When this occurs contacts (not shown) are closed which maintain the motor energized for a complete cycle even though the start pulse then ceases. However, if the start pulse is only of a short duration the lip on the reset cam will not clear the reset lever before its termination, the other contacts will not be closed to maintain the motor energized, and therefore the spring RF will rotate the shaft back to its initial position, over-shooting of this position being avoided by a retaining cam A and spring AF. In a second embodiment, Fig. 2, electrically similar to Fig. 1, a cam K is free on the shaft W and is coupled to a disc AR on the shaft by a bridge member ARH. As the shaft W rotates, the disc AR, via the bridge ARH, causes the cam to rotate, but as this happens the bridge member is wedged out of its slot N in the disc by a wedge g. When the bridge member clears the slot N other contacts are closed to maintain the motor energized and the cam K snaps back to its initial position under the action of a spring RF to await the completion of a full rotation of the shaft W when a spring AF causes the disc AR to be latched again by the bridge member ARH.
