Title: Method for producing packages
IPC: B65B47/08
Filed: 1951-03-05
Abstract: 765,452. Making containers for packaging. FLAX, V. March 5, 1951 [June 24, 1950], No. 5219/51. Class94(l). [Also in Group V] In a method of producing packages two superimposed previously formed films of thermoplastic or thermoweldable material are deformed, by the pressure of air or other gas applied between them, into conformity with the recessed faces of a pair of dies, other parts of whose faces press the films together and heat them to cause them to weld to one another, the combined effects of heat and fluid pressure producing plastic flow of the material of the films so that they form a closed or nearly closed empty container which permanently retains the shape given it by the forming operation even after removal from the dies and release of the gas pressure. The container thus formed is subsequently charged with material to be packaged and finally sealed by welding the films together. The two films may be constituted by separate sheets or strips, by a single sheet or strip folded upon itself, or by the opposite walls of a previously formed tube. The dies are preferably a pair of electrodes supplied with high frequency current. The compression of the air may result from squeezing between the dies a closed pocket formed by the films so that the trapped air is forced into the cavities formed between the recessed parts of the dies. The dies may each have more recesses than one to produce a plurality of containers. Instead of the containers being shaped by internal fluid pressure, external suction may be used, the pressure between the films then being supplied by the atmosphere or, in a closed container, by the excess of air pressure. Fig. 1 shows a number of containers with necks communicating with a channel 14 leading to the edge of the material, and the liquid filling is inserted through a thin tube reaching first to the bottom of the channel and gradually withdrawn. If the containers are to be transmitted or otherwise handled between manufacture and filling they may remain sealed under pressure to increase robustness. After filling, the individual containers 12 are sealed off by a welded seam along the channel 14. The disposition of the containers 12 may follow different patterns ; for instance they may be in one row ; the starting material then being in the form of a tube, or there may be an arrangement as in Fig. 3 in which two superimposed films are welded together along radiating lines and the divergent pockets so formed, when filled, are sealed by a peripheral weld. A similar method of closing may be followed with a row of containers, using a longitudinal welding seam. To facilitate tearing of the material to open a container the flattened parts may be notched or slit, or a strip or plate which can be easily grasped may be welded on. With large containers the flat parts of the material may be in different planes, forming ribs which assist in retaining the shape. The dies may comprise pairs of rolllers or endless bands with complementary recesses.

Title: Toilet tank supply valve assembly
IPC: E03D1/32
Filed: 1969-01-30
Abstract: 1,245,182. Fluid-pressure servomotor systems. TWENTIETH CENTURY PRODUCTS CORP. Jan.30, 1969 [Feb.1, 1968], No.5225/69. Heading G3P. A float controlled pilot valve for feeding a toilet tank has a valve assembly A 1  actuator rod 40 and float 30 mounted to swing about the axis of inlet pipe 6 to facilitate fitting the valve in tanks of different constructions. Downward movement of float 30 following a flushing operation causes rod 40 to tilt cap 20 and pilot closure member 19 about fulcrum 45 which bears an annulus 46. The consequent reduction of pressure in chamber 13 permits the inlet pressure to open main closure diaphragm 11 to inter-connect inlet pipe 6 with concentric output pipe 25 and bowl filling pipe 51 via a non-return flap valve 56 which, when so operated, closes syphon breaking air inlets 24. When the float rises again closure member 19 is re-seated and the pressure communicated to chamber 13 via orifice 47 re-closes the diaphragm 11. The inlet pipe contains a flow restrictor 67, filter 62 and rubber pipe 64 which absorbs shocks in pipe 6. The lower part of pipe 25 is cut away at 27 to permit the water to flow into the tank. The parts may be constructed of plastics material with members 23 and 8, 8 and 12 and 19 and 20 welded together ultrasonically.

Title: Improvements in and relating to Systems of Electric Motor Control.
IPC: H02P7/00
Filed: 1917-04-30
Abstract: 115,099. British Thomson - Houston Co., (General Electric Co.). April 30, 1917. Systems for controlling reciprocating motion.- An electric motor for driving machine tools or performing similar work is reversed by means of electro-magnetic switches which are energized under manual control for closing circuit, but are de-energized automatically as the motor speed drops. The motor A with interpole windings F and shunt field winding F<1> is supplied from the mains L, L<1> through a controller C reversing- contactors B, D and a series resistance contactor 11. The contactors B, D are interlocked so as to prevent either from closing until the other has opened. In the forward position of the controller, the contacts engage along the lines b, b<1> and the actuating circuit of the contactor B is completed. The contactor closes and the motor circuit is then complete-through the controller C, contactor B, actuating coil of contactor 11 and resistance R. As the current drops, the contactor 11 closes to cut out the resistance R and also to open the switch 16, thereby inserting the resistance R<1> in the shunt field circuit. This resistance is then left in circuit subject to the usual action of a vibrating relay 18. During the running period, the actuating coil of contactor B is connected across the motor armature and is independent of the controller so that, when the controller is moved to the reverse position, the contactor B cannot open until the motor speed has dropped to a predetermined, value. The movement of the controller to the reverse position closes a dynamic braking circuit through the resistance B, R. A similar action occurs at the end of the reverse run with the contactor D closed.
