Abstract: 1283518 Releasable fastenings; door operation mechanism WILLIAM NEWMAN & SONS Ltd 19 April 1971 [15 July 1970] 34268/70 Headings E2A and E2M  A door is held in an open position by means of an electromagnet and is moved to a closed position by means of a door-closer device when the current supply to the electromagnet is interrupted by fire detection or alarm means, for example. In an embodiment an electromagnet 3 Fig. 1, is housed in a casing 1, the latter also containing a slide 2 therein. The slide 2 comprises a body 4 of synthetic plastics material, for example, having a magnetic member 5 held thereto by means of a screw 6, and a pivot 11, Fig. 2, which is connected to an arm 12 of a spring door-closure device S, Fig. 6. A layer 7, Fig. 1, of foam rubber is positioned between the body 4 and the magnetic member 5 and a foam rubber liner 8 is provided in a screw-hole 9 of the magnetic member 5. The pivot 11, Fig. 2, extends through a slot 10 formed in the casing 1 and has a nylon bush 13 mounted thereon. In use, when the door is closed as shown in Fig. 1 the slide 2 is remote from the electromagnet 3.

To locate the strip 12 on the platen 40, the assembly 10 is temporarily secured to the rule 38 by inserting the rule in the slit 28, the cover strip is peeled off the tape, the rule is moved towards the platen to press the assembly against the platen, to which it is secured by the tape 16 with a bond stronger than that between the strips 12, 14, the rule is withdrawn from the slit, and the strip 14 is peeled off the strip 12. A cardboard blank is then placed on the platen to overly the strip 12 and the rule is advanced so as to crease the blanks by co-operation with the channel 22. To produce the assembly 10, the strip 12 is extruded in rectangular form and fed into a forming machine, Fig. 8 (not shown) where it is passed round and pressed against a steel roller having a circumferential recess to receive the strip and a projection within the recess to form the channel 22. The formed strip 12 is passed into a bonding machine, Fig. 11 (not shown), wherein the strip 12 and the strip 14, the latter having been extruded in shaped form, are fed over separate heaters which contact only the marginal portions of the strips, are then brought together and fed between bonding rollers which secure them together, and are then passed together with the tape 16 through a device which secures the tape to the strip 12, and the assembly is then cut into desired length assemblies 10.

A periodically operating absorption refrigeration system comprises two or more absorber units which are so controllable by a central control system in cyclic succession that at least one absorber unit is in use whilst another is regenerated and wherein a group of the units have switching members associated therewith for setting valve positions to achieve a cyclic refrigerating operation of the units, or a refrigerating operation performed by all the units or a regenerating operation performed by all the units in a group. Each unit comprises an absorber 1A, 1B, 1C, having a heater (not shown), a collector vessel 2A, 2B, 2C which communicates with condensers 4A, 4B, 4C through solenoid valves 3A, 3B, 3C and with a common distributer 6 through a valve 5A, 5B,5C and an injection valve 7 interposed between the distributer and an evaporator 8 which has a heat exchanger therein and which is connected with the absorbers through valves 9A, 9B, 9C. A manually operated shut-off valve 25 closes all the conduits behind the valves 5 and a circuit box 10 controls all the solenoid valves and heating elements in the absorbers. A manually operated control for the system and an electrical circuit therefor is described with reference to Figs. 2 and 3 and the valves are so actuated on occurrence of power failure that they assume the refrigeration position for the adsorber units.

An apparatus for extruding continuous lengths of reinforced expanded rubber comprises an extrusion machine 10, an extrusion head having a restricted die passage 17, an elongated tube 20 having the cross-section 19 of the shape of the product and forming a continuation of the die passage 17 and being of greater cross-sectional area than that of passage 17, means 50 for introducing a reinforcing string 48 to the interior of the rubber stock within the die passage 17, means 30 to 33 for heating the tube 20 to " blowing " and vulcanising temperatures of the rubber stock and means 43, 44 for stabilising the rate of emergence of the stock from the tube 20. The rate of flow of stock is greater through the passage 17 than through the region 18, the tube 20 immediately after the passage, but as the stock flows through the passage 20 expansion of volume due to " blowing " takes place and this causes the rate of flow to increase ; therefore the feed of the string 48 is controlled by synchronizing the feeding means 50 and delivery means 43, 44 causing the string to " buckle '' in the region 18 but to straighten as the stocks volume increases in its passage through the tube 20. The exterior of the stock is lubricated by a porous ring 21 and the temperatures of the heating means 30-33 is graduated. Specification 861,312 is referred to.
