Abstract: 1,067,749. Oxygen tents. MIST O2 GEN. EQUIPMENT CO. Dec. 12, 1963, No. 49097/ 63. Heading A5R. [Also in Division F4] Apparatus for conditioning the atmosphere within a patient treatment tent 3 comprises a heat exchanger 2 within the tent detachably connected to a refrigeration unit 1 outside the tent, the heat exchanger being supported on a post 28 which supports the tent and coolant being circulated between the heat exchanger and the refrigeration unit. The heat exchanger 2 comprises a vertical panel of heat-conductive material having a tortuous passage 48 for the flow of coolant e.g. water mixed with alcohol. The coolant passage is connected with the refrigerating unit, by conduits 51, 52 which extend through the tent wall and are enclosed in a tube 36 which provides a support for the heat exchanger. The lower portion of the heat exchanger panel extends into a slot 43 in the tube 36 so that condensate forming on the panel drains into the tube 36 and thence through a hose 63 to a receptacle (not shown) within the cabinet. The tube also supports a nebuliser 58 which is connected by lines 21, 59 also enclosed in the tube 36 to an oxygen supply (not shown) and to a liquid supply reservoir 60, respectively, the nebuliser thus supplying humidified oxygen to the tent. A second oxygen line 22 controlled by a manual valve is used to flush the tent interior with oxygen as desired. The coolant conduits and the oxygen lines are connected by detachable couplings 49, 50 and 19, 20 to the refrigerating unit and an oxygen bottle, respectively. The tube 36 is detachably supported by the post 28 which is adjustably mounted on the cabinet. The heat exchanger and its associated conduits may be removed for sterilisation as a unit on releasing the detachable couplings and the tube 36 from the post 28. The refrigerating unit comprises a compressor (8, Figure 4) a condenser (9) and an evaporator coil (7) which surrounds a tank (6). The tank receives coolant from the heat exchanger after it has passed through a conduit (4) coiled around the tank. Coolant from which heat has been removed is recirculated to the heat exchanger by a pump 55.

Title: Device for Bringing a Square Signal into Phase with an Incoming Pulse Series.
Inventor: BROK WILHELM FREDRIK
IPC: H03K5/00
Filed: 1967-10-31
Abstract: 1,178,430. Automatic phase control. NETHERLANDS POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 31 Oct., 1967 [1 Nov., 1966], No. 49422/67. Heading H3A. A device for locking the phase of a locally generated square wave to an incoming pulse train comprises means for comparing successive pulses in the two trains to derive a series of error signals, means for integrating successive error signals, and mens responsive to predetermined high and low values of integrated error signal to produce a phase correcting signal. Signals from the reference oscillator are fed to a counter comprising five bi-stable stages, Fig. 9 (not shown), an output from each stage being fed to an adder, Fig. 10 (not shown), and incoming data signals are fed to a differentiator circuit, Fig. 10 (not shown). The outputs from the differentiator and adder are fed to AND gates connected to the inputs of five bi-stable circuits in an integrator, so that each time a data transition occurs, the count of the five counter stages is compared with that of the five integrator stages. The integrator comprises five further stages also connected as a counter, which may be stepped forward or backward depending on whether the count difference is positive or negative. The output from this integrator counter is then fed to a gate in the input to the main counter, which allows an extra pulse to be added, or a pulse to be omitted from the counter input.

Title: Process for the production of a multifil textured yarn
IPC: D02J1/22
Filed: 1974-11-19
Abstract: 1444319 Producing crimpable tows BARMAG BARMER MASCHINENFABRIK AG 19 Nov 1974 49983/74 Heading B5B [Also in Division D1] A tow of filaments is produced by meltspinning two or more polymers into filaments under such conditions that the maximum ratio that the filaments of any of the polymers can be stretched to without breaking is 2À5. The tow of filaments is stretched at a ratio such that the filaments of at least one of the polymers are stretched beyond their elastic limit, optionally to beyond their breaking point (in which case fibres are formed from these filaments). At least one class of filament must remain unbroken, however. The tow may comprise either conjugate filaments with the filaments of one polymer being stuck to those of another, preferably as sheath and core, or separate filaments, each filament containing only one polymer, or a mixture of both. Yarns produced from such tows have an inherent tendency to crimp. This tendency is enhanced, however, and the yarn given greater cohesion, if the tow is false twisted, preferably simultaneously with the stretching. The fracture of at least one of the filament types may be assisted by passing the tow over a toothed wheel, such as is illustrated in Fig. 4, during stretching. Contact of the filaments with the teeth produces weak points at which they are more likely to break and so produce staple lengths of the weaker filaments. The filaments are preferably given the high degree of orientation required by withdrawing them from the spinneret at high rates, such as above 2500 metres/minute, preferably 2700 to 5000 m./min.

Abstract: 1476465 Copying apparatus XEROX CORP 20 Nov 1974 [27 Dec 1973] 50281/74 Heading G2X [Also in Division B6] A copying apparatus, e.g. of the type in which a heat image is formed on a delayed-tack adhesive web 10, comprises development means, e.g. magnetic brush 60; cleaning means, e.g. brush 58; an image member, e.g. web 10, capable of bearing a developable image thereon and means for moving the image member in opposite directions past the development and cleaning means. The image member moves in one direction, e.g. from spool 12 to spool 24, to receive toner particles presented by the development means and in the opposite direction for cleaning, the cleaning means being removed from its operative position as the image member moves in the said one direction to avoid detriment to the image. In Fig. 1, image-wise heat softening occurs as the delayed-tack adhesive web 10 passes the lamp 28 in contact with the original 88. The web then picks up ferromagnetic toner particles 34 and passes on to spool 24. The web reverses after the entire image has been transferred to web 10 and solenoid 53 is energized to pivot cleaner brush 58 upwardly to remove excess toner particles 34. A feed roll 74 then picks up a copy sheet from stack 69, which sheet then receives the image from web 10 as they pass the lamp 28. The copy sheet emerges at 84. In Fig. 1, the toner brush 60 is pivoted away from web 10 when the cleaner brush 58 is pivoted towards the web; in a modification, the toner brush is permanently in its operative position. Instead of using a copysheet, the developed image may be fused on to web 10.

Abstract: 1291991 Shrimp culture G E SPENCER (MARIFARMS Inc) 21 Oct 1969 51549/69 Heading A1A A method of cultivating shrimp is characterised by growing diatoms in the upper levels of a depth of saline water and to a concentration sufficient to absorb direct sunlight so that shrimp larvae growing in the water feed on the diatoms which are continuously circulated by a mechanical impeller 33 or pump and supplying oxygen through pipes 34 to maintain a minimum concentration of 2.5 ccs per litre and later, feeding the shrimp on invertebrate meat. Nutrient salts are added to the water to encourage diatom propagation and the water maintained at a minimum depth of 1.5 m and at a temperature between 20C and 32C and vertically growing plants are introduced to provide shelter for the shrimp and additional oxygens. The growing pond 52 is connected to the sea both by an inlet 59 and a pump 55 with filtered conduits 54 and contains a culture tank 32 with a hatching tank 31, having sides of woven synthetic fibre, suspended in the culture tank by means of floats 50. Similar woven fabric is used for the water inlet and outlet screening 36 and for the walls 53 of the culture tank. After spawning the adult females are removed from the hatching tank and shortly after hatching the nauplii are transferred to the culture tank. After the postlarva stage the young shrimp are then transferred to the growing pond. After the zoeal stage artemia are a particularly suitable food and preferably a pond 68 (not shown) is provided for hatching and growing artemia to be used as food with one artemia pond able to supply food for two similarly sized shrimp ponds. Where the sea water is contaminated it is passed through a sand filter tank 40 (not shown).
