Abstract: 228,133. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Jan. 25, 1924, [Convention date]. Coiling; winding and reeling.-The supply spool of a machine for helically coiling wire on a travelling mandrel wire is centrally arranged on the rotary winding head, is bored for the passage of the mandrel wire and rotates on centre points arranged consecutively in the direction of movement, centre point, bearing, centre point, bearing, the centre points being pushed into their bearings so as to keep the tension of the wire constant. The wire to be coiled is fed from a centrally mounted spool 65, over guide rollers 61, 62 on a U. shaped rotary head 50. The mandrel wire passes through a centre point 53 controlled by a spring 54 adjusted by a stud 56 and spring 55 and then through a bearing in the spool spindle 57, then through centre point 58 of the spool spindle, and then through bearing block 59 mounted in a member bridging the legs of the U-shaped rotary head 50. Thus the passage traversed by the mandrel wire is unobstructed. The ends of the centre points may be paraboloidal, and the centre points and bearings may have at their points of engagement convex surfaces turned to each other so that the centre points engage on annular surfaces on the bearings as shown in Fig. 3. The centre points and bearings may consist of tempered silver-steel. The Specification as open to inspection under Sect. 91 (3) (a) describes another form of rotary winding head for this purpose. A mandrel wire . 13, Fig. 1 (Cancelled) on which the wire 12 is coiled is fed at a uniform speed through the hollow shaft 7 of the rotary winding head 9 and through a guideway 15 carried by a box 14, which is mounted in a column 22 on a slide 19 and is electrically heated by a coil 17. The wire 12 is fed from a spool 10, Figs. 3 (Cancelled) and 4 (Cancelled) mounted on one side of the head 9 and over a guide roller 11. The spindle 36 of the spool has a centre point 37 engaging a bearing in a block 38 in a housing 31, and has also a bearing engaged by a centre point 35 carried by a stud 34 movable in a housing 30. The stud is under control of a spring 40 secured at one end to a housing 32 and adjustable at the other end by a stud 41 on bousing 33. The mandrel wire passes through a notch 42 in the stud 34. The centre points may be pushed into their bearings pneumatically or electromagnetically. This subjectmatter does not appear in the Specification as accepted.

Title: Improved method and apparatus for sterilizing sealed plastic containers
IPC: A61L2/07
Filed: 1962-01-03
Abstract: 977,423. Sterilizing liquids &c. ALOIS DUSCHEK, G.m.b.H. Jan. 3, 1962 [Jan. 5, 1961], No. 307/62. Heading A2D. [Also in Division A5] Sealed plastic containers 5 e.g. of polypropylene or polyethylene, for biological liquids, sera, solutions for infusion, injectable medicines or surgical suture material, are heated e.g. to 120-135‹C. without deformation in an autoclave 1 fed with sterilizing liquid, and the containers are cooled and pressure is relieved after the sterilization has been terminated. The plastic containers are only partly filled with the liquid, pasty and/or solid material to be sterilized and the autoclave is completely filled with water or other heat transfer liquid, except for the volume occupied by the containers. The autoclave communicates through a relatively narrow pipe 7 with a closed expansion vessel 8 of such capacity that it takes up at least the volume by which the heat transfer liquid expands when it is heated from room temperature to sterilizing temperature, as well as maintaining a compressed air cushion effecting the equalisation of pressure. A circulating system 11 and 12 for the heat transfer liquid communicates with the autoclave and includes a cooler 10. Specified other heat transfer liquids are toluene, xylene and cumene. The autoclave and expansion vessel may be provided with pressure relief valves 2 and 14 respectively. Containers of polypropylene may be heated at 135‹C. for at least 20 minutes or at 120‹C. for at least 30 minutes. Measurement by a thermo couple feeler enables a satisfactory check to be made as to whether or not the contents of the containers actually assume the desired sterilizing temperature. An operational example is disclosed.

Title: Improvements in or relating to the measurement of quantities of heat
IPC: G01K17/04
Filed: 1957-01-03
Abstract: 848,831. Measuring heat loss. NOLDGE, H., TODTEN, E., and GROBER, C. Jan. 3, 1957 [Jan. 4, 1956], No. 331/57. Class 40 (1). The amount of heat lost by a flowing medium is determined by separating a known portion of the total stream, continuously heating it to the initial temperature of the medium before the heat was lost, and measuring the amount of heat necessary to do this. In Fig. 1 a portion of the medium flowing along the tube 1 is diverted through the thin-walled bi-filar copper coil 2 past the temperature-sensitive resistor 14, which is arranged in a bridge with the corresponding resistor 13, the latter being sensitive to the temperature in the pipe 15 which represents the initial temperature of the medium. If these two resistors are unequal in value the bridge will be unbalanced and the transistor 20 will give a curient output through the coil 12 to close the relay contacts 9. Current then flows from the A.C. source 7, 8 through the heating resistor 6 until the temperature of 14 has risen to equal that of 13. The relay voltage is maintained with a slight delay due to the capacitor 24 but after this the relay is de-energised and power cut off from the resistor 6. The current supplied to the latter passes through the watt-hour meter current coil 10 which in association with the voltage coil 28 measures the total power supplied to heat the resistor 6, and from this the heat lost by the medium between points 13 and 3 can be calculated. In a modification current flows continuously through the heating resistor 6 and the bridge is balanced by adjusting the value of this current, the power being read on a wattmeter.
