Title: Sash lock
IPC: E05C3/04
Filed: 1975-11-26
Abstract: 1524229 Window fastenings Y NAKANISHI 26 Nov 1975 [27 Dec 1974 (2)] 48555/75 Heading E2A A rotatable camming bolt 2, engageable with a keeper (not shown), may be locked in the fastening position by rotation of a knob 3. The knob 3 has camming surfaces (see Fig. 7) which engage with similar surfaces on a locking member 26 and so convert rotation of the knob into sliding movement of the locking member 26, along the shaft 17 of the knob 3, between unlocking and locking positions. In the locking position legs 28 on the locking member pass through guide holes 34 in the bolt 2 and engage with receiving holes 36 in the base 1, thus preventing rotation of the bolt 2. Rotation of the knob 3 from this position permits the locking member 26 to slide, under the action of spring 41, up the shaft 17 until the legs 28 are free of receiving holes 36, thus permitting rotation of the bolt 2. For ease of rotation of the bolt, a washer 43 made of a self-lubricating plastic, may be inserted between the bolt 2 and the base member 1.

Abstract: 1324789 Spreaders SATECO 19 Oct 1970 [28 Nov 1969] 49442/70 Heading AID  A spreading device for substances in powder form comprises a receptacle 2 with an outlet at its lower end, characterised in that a pivotable spreading table 5 below the outlet is in the form of a box with a porous top surface and in operation the substance coming through the receptacle outlet 4 on to the top surface is fluidized by means of compressed air fed to the box 5 via an adjustable valve 7. A hopper 4 is preferably provided between the outlet and the table which is pivotable about a horizontal axis and the air is supplied via piping 8 from a compressor 3 to the valve 7. The substance passes from table 5 through an adjustable slot operated by a sliding vertical flap 6 or rotary hood; the whole rear section being surrounded by a flexible skirt 10. The rate of spreading is determined by adjusting the inclination of table 5, the position of flap 6 and the air flow rate controlled by valve 7. These parameters may be adjusted by the operator by means of levers 11, 12, 13 or automatically according to the speed of travel of the carrier vehicle. The receptacle 2 is preferably arranged with the bottom 2e inclined at approximately 10‹ to the horizontal. The double bottom 2e may have a porous top surface so that substance in the receptacle may be fluidized by air from pipeline 9 and the substance is hence conveyed to hopper 4. A screw conveyor may, alternatively, be used. To ensure uniform distribution of the substance over the width of table 5 a pocket-type metering device of conveyor (not shown) may  be provided in hopper 4 and these may also be driven in accordance with the speed of travel of the carrier vehicle.

Title: Device for fitting caps to bottles or the like
IPC: B67B3/14
Filed: 1965-11-23
Abstract: 1,099,728. Capping bottles. L'ALUMINIUM FRANCAIS. Nov. 23, 1965 [Nov. 24, 1964], No. 49732/65. Heading B8T. A tool for crimping a cap 2 on a bottle 1 has a pusher 300 and a number of resilient blades 220 which crimp the cap to the bottle as it moves upwards, its neck engaging the pusher 300 and moving it so that a spring 230 between the pusher head 310 and a support ring 210 of the resilient blades is compressed. The cap 2 on the bottle 1 is engaged by a ring spring 222, which may be of helical form. As the bottle neck advances further upwards, it forces projections 221 on the resilient blades 220 to press against a frusto-conical lip 131 on the end of a fixed sleeve 100. This causes the ring 210 to be pulled downwards as the blades 220 are forced further apart. The upward movement of the bottle 1 causes the spring 222 to contact a lip 24 on the cap 2. A stop 322 on the pusher 300 then engages the support ring 210 of the resilient blades and causes the blades 220 to move up with it. The projections 221 slide inside the frusto-conical lip 131 and press the lip 24 of the cap under the rim of the bottle 1. The bottle 1 is moved downwards and pulls the resilient blades with it, until they reach the edge of the lip 131, Fig. 4 (not shown). The bottle 1 can now be disengaged from the tool, which returns to its original position. In a modification, Fig. 5 (not shown), a frusto-conical lip (130) on a fixed housing, is engaged by slidable projections (221) arranged mid-way along instead of at the end of the resilient blades (220). A device for receiving and positioning the caps before the bottle is introduced to the tool is provided. It comprises three fingers (142) which are urged by springs (144) towards the axis of the tool. Alternatively, the caps 2 may be held in position by other means, e.g. magnetic means. Instead of the bottle 1 moving up with the tool, the tool may move downwards on to the bottle.

Abstract: 1,189,929. Applying a coil to an uncoiler. VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE A.G. 21 Oct., 1968 [6 Nov., 1967], No. 49749/68. Heading B3E. Apparatus for applying coils to an uncoiler comprising a lifting table 3, which may be wheeled, and which lifts the coil 23 to the level of the uncoiler axis 2 and means 5 for de-energizing the lifting drive means 4 when the axes of the coil 23 and uncoiler 2 are aligned, is characterized by a detector 9, which is connected or connectible to the lifting table 3 to move in unison therewith in the opposite direction at a speed which is equal or proportional to the speed of the lifting table 3 and which detector 9 is adjusted to have in an initial position the same distance from the axis of the uncoiler as the contact surface between the lifting table 3 and the coil 23 and when contacting the periphery of the coil generates a signal and/or de-energizes the lifting drive means 4. The solenoid valve 5 and a solenoid valve 14 are activated at the same time so that a pressure member 12 moving from the inoperative position indicated by dotted lines follows the upgoing stop 11, engages it, and moves upwardly in unison with it. The movement of the lifting table is transmitted by parts 17-22 to a holder 8 so that a radiator-receiver 9 of a reflected light barrier moves oppositely to the lifting table 3 in such a manner that the distances A and B are always the same. When the light beam is tangential to the coil 23, the axes of the coil and uncoiler are aligned, and the light beam is partly obstructed so that the receiver 9 delivers a changed electrical value which de-activates the solenoid valve 5. In one embodiment a follower 24 is centrally disposed in the lifting table 3 to eliminate the need for a consideration of the angle of inclination of the supporting surfaces 3<SP>1</SP> in the selection of the transmission ratio of pinions 17 and 20. In another embodiment the light barrier is replaced by a limit switch 26 having an actuating plunger 27. The initial position is adjusted so that the distance B is measured from the plunger 27 when it is in the activated position indicated by dotted lines.
