IPC: F25B35/04
Filed: 1938-08-05
Abstract: 517,700. Refrigerating. BLOCH, R., and GOLDBERGER, F. Aug. 5, 1938, No. 23201. Convention date, Aug. 6, 1937. [Class 29] Absorption systems. - Generator-absorber vessels for reversing systems using solid absorbents such as calcium chloride comprise a number of cylindrical absorbent chambers 1 connected together by ribs 2 parallel with their axes. They may be grouped to form a chamber 3 heated internally by hot water, gas, steam or electricity. Where a gas burner 4<11>, Fig. 4, is used a baffle 2<1> is placed above the flame and the whole may be placed in a casing 5 having air holes 8 at the sides and a hinged lid 6 which is shut during the heating period and open during the cooling period, the control being effected by hand, or thermally as described in Specification 500,002. A perforated baffle 13 may be located below a hole 14 in the lid. A thermal control element as described in Specification 481,158, [Group XXXVII], may be located in a recess 11, Fig. 3, in a metal mass 9 connecting two cylinders. A group of cylinders and ribs may be formed of two complementary metal stampings, Fig. 5, welded together at the edges of the ribs. A groove 15 along one edge of each stamping provides a communicating vapour conduit. The solid absorbent may be placed in sealed glass vessels or wire gauze tubes 18, Fig. 7, placed in the grooves of the stampings before assembly. A spiral wire 20 or a wick is placed at the side of the absorbent container to provide a vapour path after the absorbent swells up. Where glass vessels are used they are fractured when the absorbent swells. The use as absorbent of manganese and praseodymium chlorides is mentioned.

Prior to the commencement of the filling of a bobbin with yarn, a " tag-end " is formed by wrapping a piece of yarn around one or more grooves or channels in the periphery of the base of the bobbin, then around pins or projections on a bobbin support which may also be the means whereby the support is driven by the bobbin, and under a yarn retaining device e.g., a notched screw-head. The groove(s) may extend between opposing faces of the bobbin flange and be inclined e.g. helical or helicoidal, partially or completely encircling the base for one or more turns, and have flared entrances for the yarn. A clearance between the bobbin base and the support is provided, as by the use of a spacing collar, to permit entry of the yarn and /or the yarn is directed over the bobbin base by a moveable guide.

Roads and ways, arrangements of.-At a railway crossing, alternative routes are provided for road traffic, one a level crossing 11 and a second which includes travelling inclined roadways 19 for bridging the railway 10 when the level crossing is closed. In the form shown, the endless track 19 is driven from a drum 20 rotated through gearing 27 by an electric motor 26 which is started and stopped by a switch controlled by electromagnets energized by contacts on the track. The driven shaft 25 of the motor also operates through a clutch 24 controlled by an electromagnet 28 to rotate a drum 29 for raising the gates 12 - - 15 which close the roadway 11. The arrangement is such that the left-hand gates 12, 13 are closed first, the gates 14, 15 being closed after an interval to permit traffic between the gates to pass out. Fig. 7 shows two cables passing from the drum 29 to the gates 12, 14, the rotation of the drum first raising the gate 12, the gate 14 being raised when a weight 40 contacts with stops 41. Catches holding the gates open are electromagnetically released when the train has passed and at the same time the electromagnets 32, 28 are de-energized to declutch the drum 29 to permit the weight 40 td fall and open the gates.
