Abstract: 1,213,984. Inertia reels. KANGOL MAGNET Ltd. 13 March, 1968 [21 March, 1967; 8 Sept., 1967], Nos. 13291/67 and 41209/67. Heading A3V. [Also in Division F2] An inertia reel device 10 includes a reel 25 on which is mounted a ratchet wheel 45 rotatable therewith, a pendulum 50 mounted so that it can pivot through a limited angle in all directions about a pivot point, an operating member 52 secured to the pendulum having a top surface arranged to engage with a bottom surface of a thrust transmission member 57 which is mounted for movement, when the device is mounted for use, in a vertical direction, the top surface of the operating member and the bottom surface of the thrust transmission member are so shaped that angular displacement of the pendulum from the vertical causes upward movement of the thrust transmission member which causes a pawl 41 to engage the ratchet wheel 45. The operating member is preferably a hemisphere mounted on the stem 51 of the pendulum having a plane top surface normal to the stem. The pawl and ratchet teeth are so shaped that when they are engaged and torque applied in a direction to inhibit rotation by means of the pawl the pawl is retained in engagement until the torque is removed. The pawl is normally spring biased 60 out of engagement with the ratchet. In a further embodiment the pendulum and thrust transmission member sub-assembly is mounted such that the casing may be non-vertical but the pendulum remains so.

Filed: 1960-12-01
Abstract: 898,426. Control of A.C. motors. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. Dec. 1, 1960 [Dec. 14, 1959], No. 41333/60. Class 38 (3). [Also in Group XXX] A remotely controlled reversible three-phase motor for railway switch points is connected for starting to two phases only of a three-phase supply and provision is made for a supervisory current. As shown, for operating the points, winding III of the motor is connected to supply lines X and Y via reversing relay contacts 341, 342 and winding I is connected to supply lines X and Z via contacts A11 and lead L4 so that the motor begins to run. In a short time A13 is closed by switch points member T so that winding II is connected to lines Y and Z and the motor is then running in three phase delta connection. In an alternative arrangement (Fig. 2, not shown), for starting two of the motor windings are connected in series across one phase of the supply while the third winding is connected across another phase. When the member T begins to move, the motor windings are rearranged for running in three-phase star connection. In either case the motor is stopped by the opening of switch A23 (which by then is in circuit) by the member T. Supervisory current flows from X to R through either indicator relay B1 to B2 according to the position of the member T, and only when it is at rest in an end position. The current traverses all four control lines L1 . . . L4 and two of the motor windings. If the points are forced into a wrong position, e.g. by the passage of a train, the supervisory current follows a different path of lower impedance and a fuse S1 is blown, thus indicating an error.

Title: Improvements in machines for the manufacture of slabs, tiles and the like
IPC: B28B3/02
Filed: 1958-12-23
Abstract: 897,308. Moulding tiles &c. GIANNELLI, G. Dec. 23, 1958 [Dec. 28, 1957], No. 41414/58 Class 87(2). A compression moulding machine for making tiles, slabs and the like comprises a die structure, associated with a vibrator 11, supported resiliently on a structure 1 and arranged to be pressed between an upper and a lower pressing structure and a spacing member 16, loosely supported by the die structure, between the die and the lower pressing structure, which spacing member can be released from engagement with the die while vibration takes place. Each die structure comprises a frame 2 and cover plate 10 which can be moved towards and away from each other, rubber sealing members being interposed, by hydraulic cylinders 12 and pistons attached to the plate and die frame respectively. The resilient supporting means of the die structure comprise a carriage 7 with rollers 8 which run on tracks 9 in the structure 1 and have bushings 6 in which slide rods 5 depending from the frame 2, the bushings floating between upper and lower springs 4. In the vibration position, Fig. 2, the spacing member 16, which is of box formation with the under surface of its top normally resting on the heads 17a of studs 17 depending from the plate 10, is raised, so as to be clear of the head 17a, by a lifting element 19 actuated by a hydraulic cylinder 20. The distance between the underside of the plate 10 and the stud heads 17a allows enough play for the top of the spacing member 16 to be out of contact both with the stud heads and the plate, and the support of the dies during vibration is thus wholly resilient, the studs 17 passing loosely through holes 18 in the top of the member 16. The stud heads may be conical. When the frame has been turned about a vertical axis to the pressing position, Fig. 3, the press ram descends to compress the material in the dies and the spacing member 16 is pressed upwards against the cover plate 10 by a hydraulic piston 22, the raising of which is limited by studs 24, a return spring 25 being provided to hold down the piston 22 until hydraulic fluid has been supplied to the cylinder 23. After pressing, the member 16 is lowered, taking with it the plate 10, by an amount which leaves sufficient clearance between the plate and the dies for the moulded tiles to drop on the plate and be removed.

When compressed air is indroduced into the cylinder through cavity 8 and duct 10', the piston and rod 5 move to the left in (Fig. 1) a shoulder 16 abutting a shoulder 15 to withdraw the righthand end of the plunger 14 from duct 9 and compress the spring 13. As the piston approaches the left hand end of the cylinder, the washer 19 engages the flanged body 21, springs 18 and 23 are compressed and the gasket 25 abuts the wall 20 to prevent air passing from the cylinder to the duct 27. The air-flow from the cylinder through duct 28 can be controlled by adjusting the throttling member (30). When the piston is moved to the right by introducing compressed air to cavity 26, the spring- loaded plunger 14 closes the port 9 and the airflow from the cylinder through duct 10 may be controlled by adjustment of the throttling member (12).
