Title: Containers
IPC: B21D51/26
Filed: 1970-09-07
Abstract: 1311177 Jointing CONTINENTAL CAN CO Ltd 7 Sept 1970 [15 Sept 1969] 42731/70 Heading B3V [Also in Divisions B5 and B8] A container closure 11 is sealed to a container body 10, e.g. a can by applying a heat softenable bonding agent 20 to a peripheral portion of either the closure 11 or body 10, placing the closure 11 on to the body 10, applying ultrasonic vibrations to the container assembly to soften the bonding agent and allowing the bonding agent to harden. The closure and/or body may be made of metal, e.g. aluminium, steel or plastics material and the closure may be of plastics matorial with a metal peripheral portion. The bonding agent 20 may be located in a closure channel 19 as shown, in a body channel or retained on a flange, shoulder or the plain walls of the closure or body. The bonding agent may be a synthetic organic resin and many examples of suitable thermoplastic and thermosetting resins are given. The inner surface 22 of the closure, may be provided with an enamel coating 23. The skirt 17 of the channel 19 may be hemmed. The body wall 13 may be outwardly flared at its open mouth and may have its upper edge 14 and side surface adjacent thereof chiselled, ridged, serrated or knurled.

Title: Method to localise faults in carrier frequency systems
IPC: H04B17/40
Filed: 1965-10-08
Abstract: 1,064,592. Supervising repeaters. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Oct. 8, 1965 [Oct. 15, 1964], No. 42759/65. Heading H4R. For the purpose of locating faults, a supervisory signal of increasing amplitude is applied to one path of a repeater system, and an amplitude-filter is provided at each repeater to transfer the signal to a return path when the amplitude is within a certain range in order to control an indicator. The amplitude-filters are similar; passing a range of about 0À4 Neper, and thus are operative in turn on account of the line attenuation as the emission level is increased. The two paths may be one a carrier path and one an audio path, or both may be carrier paths. The frequency employed for the supervisory signal is one that is not used for communication and is selected by a filter at each repeater.
Patent GB-433682-A (GB)
Abstract: 433,682. Thermal switches. BRITISH THOMSON - HOUSTON, CO., Ltd., Crown House, Aldwych, London. March 20, 1935, No. 8718. Convention date, March 21, 1934. [Class 38 (v)] [See also Group XXXVIII] A thermally operated relay adapted to be selectively moved from the position shown to one or other of two positions by carrier currents of long or short duration comprises a toggle, the two arms 12, 13 of which are pressed towards each other by a spring 14, and a bimetallic strip 6 controlled by a heating winding 7 and carrying a U-shaped member 18, Fig. 5, adapted to actuate the arm 12. The arm 13 carries a contact 17 adapted to engage a fixed contact 17<a> but in the position shown, the contacts are held apart and the toggle prevented from collapsing into its full left position by a pin 22 on the arm 12 engaging the top of the member 18. A carrier current will energize a relay 4 and so close the circuit to the heating winding 7 which will cause the strip 6 to bend to the right and release the pin 22 so that the toggle collapses and contacts 17, 17<a> engage. If the current is of short duration this is all that will happen, subsequent cooling of the strip 6 producing no further actuation. If the current is of long duration, the strip 6 will bend still further to the right and the left hand arm of the member 18 will engage a screw 19 on the arm 12 and move the toggle to the right over the dead centre so that contacts 17, 17<a> will separate. Subsequent cooling of the strip 6 will cause a screw 20 to push the toggle back again to the position of the figure in which the contacts are still separated. The bimetallic strip 6 may be provided with another strip 6<1> connected between the member 18 and the mounting block 8 to compensate for variations of ambient temperature. In a modification, Fig. 4, (not shown), the contact 17 in its right and centre positions engages another contact 25, and an application of this form of the invention to control of a water heater 27 is shown in Fig. 6. Normally lines 2 supply current to the heating winding 28 through the current coil of a wattmeter 30 and the contacts 17, 17<a> which are closed. At times of peak load the power company by means of a carrier current of long duration causes the contact 17 to move away from the contact 17<a> and engage the contact 25. This breaks the circuit to heater 28, but an auxiliary heater 29 can now be put into circuit if desired by the consumer through a hand switch 35, the power consumed then being measured by another wattmeter 33 so that a higher rate may be charged. Later on, by sending a short impulse of carrier current, the contact 17 moves back to its original position.

The crossbeam 4 has a rectangular cross-section and is provided with rails 7, 8, 9 for guiding the slide 5 between the upright 2 secured to a table 1 carrying the workpiece 10. The upper part of the slide above the crossbeam carries a drive means in the form of a motor and changespeed gearing, and the part of the slide beneath the beam carries only the bearings for a shaft supporting the tool, such as a circular saw blade 6. The shaft is connected to the drive means by gearing 13 located in vertical parts 12 or 14 of the slide. The parts of the slide below the crossbeam and the vertical parts have a short length B for permitting maximum longitudinal movement of the slide between the uprights 2, 3 whereas the upper part of the slide has a length L for maximum guiding effect of the slide.

Abstract: 1329562 Fluid pressure actuator SPERRY RAND AUSTRALIA Ltd 16 Sept 1970 [25 Sept 1969] 44171/70 Heading F1D In a double-acting actuator, Fig. 1, a pair of relief valves 46, 47, Fig. 9, in passageways through a piston assembly 2, 3, connecting the chambers 5, 6 of a cylinder 4 prevent a build-up of pressure behind the piston assembly except at the end of each stroke when relative movement between parts of the piston assembly 2, 3 closes the respective passageway, Fig. 9. The pressure buildup is detected by a pressure senser 86 Fig.17 which produces a signal at some remote point. A pressure source and drain are connected via a selector valve 85 to lines 31, 32 which are respectively connected to the chambers 5, 6 via ducts 28, 29, spring-loaded valves 23a, 23b, and ducts 25, 24, Fig. 11 the duct 25 linking with the chamber 5 via a conduit 15, Fig. 1. The pressurized fluid in, e.g. duct 28 as shown, opens the associated valve 23a and also acts on a shuttle 27 which opens the other valve 23b. The piston assembly comprises an inner portion 2 having a rod 7 for connection to, e.g. a valve member 9, and an outer portion 3 comprising a pair of inner sleeves 38, 39 each having an end shoulder 42, 43, and an outer sleeve 41, slidable on the sleeves 38, 39 between the shoulders 42, 43. Near the end of each stroke, the sleeve 41 engages an abutment 67, 68, the sleeves 38, 39 and the inner portion 2 continuing to move until the sleeve 41 engages one of the shoulders 42, 43, closing the relief passage opening 63, or 64. Safety valves (71, 72) Figs. 15, 16 (not shown) prevent pressure build-up in the chambers 5, 6 when the actuator is idle and are located respectively in a passageway 77 connecting duct 25 with duct 29 and in a passageway 83 connecting ducts 24 and 28, Fig. 11. In a second embodiment, for actuating rotary members via a rack on the piston, and a pinion, a pair of cylinder heads 111, 118 each has an inlet-outlet opening 128, 129 communicating with a valve 123a, 123b and pipe 192, 193 leading to the space behind a shuttle 127b, 127a on the opposite head, so that pressurized fluid opens the associated valve to enter one chamber and acts on the shuttle in the opposite head to open the other valve to allow the fluid to escape from the other chamber. The relief valves are located externally of the cylinder and are rendered inoperative when the piston heads 189 engage adjustable axial abutments 202, 203 through which the relief passages extend. It is stated that the operating fluid may be gas or liquid, and the invention is also applicable to diaphragm or bellows actuators.
