Title: Drive mechanism for vertical sun control strips
IPC: F16H37/00
Filed: 1975-03-12
Abstract: 1476872 Louvre blinds H GROSS 12 March 1975 [15 March 1974] 10287/75 Heading E1J [Also in Division F2] A drive mechanism for pivoting the vertical strips of a sun blind and subsequently moving them horizontally, comprises an input shaft 4 and output shafts 6 and 7, the shaft 6 being associated with the pivoting means and the shaft 7 with the displacing means. The input shaft 4 has a sun pinion 8 which meshes with a planet gear 12 rotatably mounted in a planet carrier 9, the carrier 9 having gear teeth 17 meshing with a gear 18 to drive output shaft 6. A gear 26 mounted coaxial with gear 18 has a different number of teeth from gear 18 so that relative rotation occurs between them, and stop means between these gears stop shaft 6 after a predetermined relative rotation between the gears 26 and 18. When shaft 6 is stopped shaft 7 is rotated through a planet gear 13, integral with gear 12, which meshes with a gear 14 to drive the shaft 7 through a shaft 10 and gears 15 and 16. The torques applied to the shafts 6 and 7 are such that shaft 6 will always rotate, rather than shaft 7, until the stop means operate. The shaft 7 is driven through a slip coupling 21, 20 which allows rotation of the gearing if the shaft 7 is prevented from rotating. A limit switch may be provided to switch off an electric motor driving input shaft 4 through a pulley 5 when the blind is fully open or closed, which limit switch may be operated by a pair of gears acting in similar fashion to gears 18 and 26 and driven by output shaft 7. The input shaft 4 may be rotated manually, through a ball chain or a crank handle.

Title: Improvements in or relating to devices for measuring angle of turn and to automatic control and stabilizing systems
IPC: G01C19/56
Filed: 1943-06-25
Abstract: 611,015. Automatic control systems. SMITH & SONS (ENGLAND), Ltd., S., (formerly SMITH & SONS (MOTOR ACCESSORIES), Ltd., S.), and MEREDITH, F. W. June 25, 1943, No. 10338. Drawings to Specification. [Class 38 (iv)] Alignment.-A body, such as a, turntable, mounted on another body subject to turning about an axis Z is stabilized against turning by a mass mounted on the first body and forced to oscillate in the direction of an axis X normal to the axis Z. When turning occurs vibrations in the direction of an axis Y normal to X and Z are detected and caused to control a motor operating to restore the first body to its initial position. If, due for example, to time lag, this restoration should be incomplete a monitoring device on the first body is caused to apply additional control to the motor to effect completion. The turn-responsive device is similar to that described in Specification 611,005, [Group XXXVIII], in which the oscillating mass is mounted on a tine (fixed on the Z axis on the turntable), but has no applied damping or restraint on movements in the Y axis and may be arranged in an evacuated envelope; its natural frequency in X and Y directions is made as nearly as possible the same. An electrical voltage proportional to the angle of turn is derived from it and applied to an electric motor geared to the turntable and a generator on the motor shaft adds a voltage proportional to the motor speed. The monitor is a compass preferably of the kind described in Specification 578,303, [Group XXXVI]. According to the Provisional Specification, the motor may be operated by an integrated signal from the turn-responsive device. Further, a damping drive may be applied in the direction of the Y axis as in Specification 611,005, [Group XXXVIII], the signal may be generated electromagnetically instead of by a quartz crystal.

Filed: 1974-03-08
Abstract: 1426994 Bag filling devices LIBRAWERK PELZ & NAGEL KG 8 March 1974 [9 March 1973] 10493/74 Heading B8C A bagging device includes a feed device 1 having a discharge hopper 2 below which is located a horizontally reciprocable feed hopper 3 running on rails 8 and driven by a cylinder 9. The feed hopper is provided with a discharge pipe 4, against which a bag 6 can be clamped by clamp 5, and is so located and shaped relative to the discharge hopper that material from the hopper can flow into it at any position between the two extremes illustrated in the figures. In operation, a bag is clamped over the discharge pipe, closure of the clamp opening a shut-off member 2a in the discharge hopper to allow material from the discharge hopper to fall into the feed hopper and thence into the bag. The feed hopper is then transferred from the bag attachment position of Fig. 1 to the ejection position of Fig. 2, during which transfer discharge of material from the discharge hopper into the feed hopper and thence into the bag continues. When the bag is filled it is unclamped and loaded on to take-off conveyer 10. Unclamping of the clamp closes the shut-off member and the feed hopper is pushed back to its starting position in Fig. 1 to commence a fresh bag filling cycle. By enabling material to be fed from the discharge hopper to the feed hopper and thence to the bag during movement of the feed hopper to the ejection position, the overall cycle time of the device is reduced. A further reduction in cycle time may be achieved by providing the outlet pipe of the feed hopper with a shut-off member (see Figs. 3 and 4, not shown). In further embodiments, the feed hopper is connected to the discharge hopper by a parallelogram linkage mechanism or by a flexible hose, the feed hopper being linearly reciprocated. In a yet further embodiment, the feed hopper is pivotally connected to the feed device to swing from a bag application to a bag take-off position. A flexible base directs material from the feed device to the feed hopper.
