Patent GB-915783-A (GB)
Title: Filter bodies and process of preparing same
IPC: A24D3/08
Filed: 1961-04-13
Abstract: A rod-like filter for cigarettes comprises a plurality of polyolefin fibres extending there along and bonded together with a polyolefin material of lower melting point distributed throughout the mass of fibres.  A crimped and blended tow, of total denier 50,000, composed of 17,000 filaments of isotactic polypropylene of melting point 170 DEG  C. and 3,000 filaments of high density polyethylene of melting point 130 DEG  C., is drawn off continuously from a supply at about 300 feet per minute by means of circumferentially grooved godet rolls.  The tow is then opened up by means of air jets into a thin flat ribbon and taken up by a flattening roll system whence it is passed through a heating chamber wherein it is heated to between 115 DEG  C. and 120 DEG  C., the applied heat being controlled by the speed of the tow passing through.  The ribbon of tow, while passing through the heater, is progressively contracted to a width of about 16 mm. by a set of godet rolls with peripheral grooves at the discharge end of the heater.  The tow is then led into a funnel-shaped condensing former and the resulting rod is passed through a cooler, cut into suitable lengths and wrapped to form filter plugs.  The filaments for use in the tow are obtained by melt extrusion through spinnerettes, sized to yield filaments of 6.25 denier, then blending in the desired proportions to form a mixed tow, which tow is then stretched and relaxed to give a net stretch ratio of 1.0 to 2.5.  This stretching ratio produces partial molecular orientation of the fibres and is 25% of that required for full molecular orientation.  The fibres of greater melting point should be at least 50% greater in total weight than the lower melting point fibres in the blended tow.

Abstract: 700,284. Refrigerating; temperature-responsive actuating elements: RANCO, Inc. May 28, 1952 [Jan. 19, 1952], No. 13525/52. Classes 29 and 64(2) [Also in Group XXXVII] A defrosting control comprises means operable automatically at regular time intervals, e.g. a clock driven cam 32, or at intervals selected manually, e.g. by a knob 39 on the shaft 33 of the cam 32, for causing intermittent defrosting cycles and a thermally responsive expansible element 70 on the evaporator E adapted to expand when the temperature of the evaporator is at or below the freezing point of water, to allow defrostirig, and to contract when the temperature rises above the freezing point, to prevent or terminate defrosting cycles. The evaporator E is defrosted by an electric heater 15 connected between line L' and a spring contact strip 22 with a contact 26. The motor M driving the compressor C of the refrigerating unit is connected through the ordinary thermostatic switch 13 with a contact strip 20 having a contact 24 and the line L 2  is connected to a central contact strip 21 with double contacts 25. The contact strips 20, 22 are rigidlyconnected by an insulating block 28 passing freely through an opening 29 in the contact strip 21. The cam 32 engages the strip 20 and is driven one revolution a day by a synchronous motor 35. A latch 50 is adapted to be raised into the path of the strip 21 by the freezing of water in the thermal element 70 on the evaporator, the expansion due to the freezing of the water in a sealed chamber 74 acting through a diaphragm 75 and non-freezing liquid in a capillary tube 65 and chamber 54 raise the latch 50 through a plunger 56. When a notch in the cam 32 allows the contacts 20, 22 to move to the left the latch 50 retains the contact 21, breaking the motor circuit and energizing the heater 15. As soon as the water in the chamber 74 melts the latch 50 is lowered by a spring 48 and the contact strip 21 freed to make the motor connection. and break the heater connection. So long as the water in the chamber 74 remains unfrozen the latch is not raised' and defrosting cannot take place. The capillary tube 65 and chamber 54 are filled with non-freezing liquid by a connection 86 sealed at 87. Accidental loss of the non- freezing liquid in the chamber 54 or the water in the chamber 74 prevents defrosting. Slip clutch means are provided to prevent movement of the synchronous motor 35 when the cam 32 is rotated manually by the knob 39.

Filed: 1947-05-23
Abstract: 639,000. Automatic brake regulator. TECALEMIT SOC. ANON. May 23, 1947, No. 13938. Convention date, June 20, 1946. [Class 103 (i)] The invention relates to an arrangement for comparing the speeds of more and less heavily braked axles on a vehicle, whereby the locking of the more heavily' braked axle operates to effect a reduction in the braking pressure. A first more heavily braked axle (not shown) has a pulley coupled by belts 5, 51 to a pulley 3 freely rotatable on a less heavily braked axle 4, the pitch diameters of the two pulleys being slightly different so that when neither axleslips, the pulley 3 is rotated slowly on the axle 4. A ratchet pawl 6, rotating with pulley 3, normally slips over the teeth on a wheel 8 which rotates with axle 4 and is urged outwardly by a spring 10. In the event of the wheels on the heavily braked axle beginning to lock, the speed thereof may be reduced sufficiently to reverse the relative rotations of the pulley 3 and axle 4 so that in changing its position, the pawl 6 straightens and forces the wheel 8 inwards against spring 10, thereby through lever 14 opening a valve 11 which reduces the braking pressure. In a modification, shown in Fig. 5, the pawl and ratchet device is replaced by a hollow pulley 16 coupled to an axially slidable member 18 by means of tilting levers 19 having spherical end bearings, the movement of member 18 opening in succession valves 26 and 26<SP>1</SP> to control the braking. The reduction in braking pressure may be applied to a single pair of axles, all the axles of a vehicle, or every axle of a train as circumstances may require.
