Title: Obstetric device for livestock
IPC: A01K15/00
Filed: 1961-11-09
Abstract: 916,239. Obstetric appliances. KASPAR, H. Nov. 9, 1961 [Nov. 9, 1960], No. 40179/61. Class 81 (2). An appliance for assisting parturition in livestock comprises means adapted to be placed against the body of the dam and provided with a tube on which is mounted two holding means for slings attachable to the legs of the animal to be born, said holding means being capable of displacement in such a manner that the leg slings may be tensioned alternately. A rubbercovered support member 27, provided with a hemispherical boss 28, is fixed to one end of a screw-threaded tube 1. Rings 7 and 10, slidable on tube 1, are interconnected by a bar 8 supporting a hook 2 and pivoted at 5 to a lever 4. A ring 13, slidable on tube 1 and disposed between rings 7 and 10, carries a boss 12 disposed in an aperture 11 in bar 8, and also carries an abutment 15 engaged with the screwthread on tube 1 by the pressure of a spring 24 interposed between abutment 15 and an abutment 9 on ring 7. A hook 3 is similarly carried by a bar 16 fixed to a ring 17 slidable on tube 1 and pivoted at 6 to lever 4. A ring 21, slidable on tube 1, carries a boss 20 engaged in an aperture 19 in bar 16, and also carries an abutment 23 engaged with the screw-thread by the pressure of a spring 25 interposed between abutment 23 and an abutment 18 on ring 17. In use the support 27 is placed against the dam beneath the vagina, and the hooks 2 and 3 are connected by slings to the respective emergent legs of the young animal. By pivoting the lever 4 to release the pressure of spring 24, abutment 15 may be re-engaged with tube 1 farther from support 28 to tension the sling attached to hook 2. By pivoting lever 4 in the opposite direction and thereby re-engaging abutment 23, the sling attached to hook 3 may next be tensioned. A further releasable hook 26 is also provided.

Title: Instruments for measuring the magnetic susceptibility of a mixture of gases, particularly of a mixture the oxygen content of which varies rapidly
IPC: G01N33/00
Filed: 1968-08-23
Abstract: 1,236,825. 825. Measuring oxygen content electrically. HARTMANN & BRAUN MESS UND REGELTECHNIKA.G. Aug. 23, 1968 [Aug. 31, 1967], No. 40453/68. Heading G1N. Apparatus for determining the oxygen content, in a mixture of gases comprises a gap 4 in amagnet 1 on which is an energizing winding 2 supplied with a pulsating direct current from a diode 3 and an A.C. supply, which gap is filled with samples of a test gas flow, 7, and a reference gas flow, 8, through valves 9, 10 respectively and is exhausted through a discharge tube 13 so that mixing occurs only in the uniform field regions, none occurring at the junctions between the gap and the feed tubes, 11, 12, at which are created non-uniform field regions the resultant differential pressure, registered by capacitor microphone, 21, providing a measure of the relative magnetic susceptibilities. The differential pressure variations are coupled to a detector, 24, synchronized from an auxiliary winding 25 and displayed on a chart recorder, 26. For gas pressure less than atmospheric a suction pump, 17, exhausts the chamber through valves 14, 16 and buffer stage, 15, pressure being indicated by U-tube 18. To reduce errors arising from magnetostriction and/or core vibrations an analysis chamber is of rigid mechanical structure comprising two soft-iron sheets (34, 35) Fig.2 (not shown) fitted tightly between the parallel poles of the magnet and is sealed by abrass frame (36) compressed between them the core 1 being constructed of high permeability laminations. Vibration effects may be further reduced by mounting the analyser chamber separately from the magnet. In another embodiment, Fig. 5, where no reference gas is available, a reference gas is provided from the carrier gas in a feed tube, 45, heated by an element 47 and supplied with the test gas, the measurement being carried out as described above. The instrument may be further simplified provided the heated gas may be cooled to its original temperature before passing through the heterogeneous zone 44 by supplying test gas through the valve 54 only, discharging it through the valve 55 and dispensing with items 56, 57 and the tube between valves 54 and 55.

A method of making a metal/oxygen battery comprises applying two spaced apart cathode layers, one adjacent one edge and one generally centrally disposed on one face of an air-permeable sheet of electrically conductive material, applying an anode layer on each surface adjacent the edge opposed to said one edge, applying electrolyte resistant absorbent material to the outer surfaces of the anode, folding the sheet to a generally S-shaped configuration and interleaving with a further similarly folded sheet so that the two cathode layers which face one another have the anode layers on the other sheet therebetween, and positioning an air-permeable, electrically insulating separator between adjacent uncoated surfaces of the sheets. The coating may take place on a continuous web of material which is then cut into sheets.

When a solenoid operated valve 17 is shifted to the left, chamber 10 is connected to passage 21 containing a second pilot valve 26 set to open at a lower pressure than valve 13. When valve 17 is shifted to the right, chamber 10 is connected to passage 22 containing a third pilot valve 29 set to open at a pressure different to that of valves 13, 26. The various valves can be in a common housing or in a bank of housings.

Title: Improvements relating to the treatment of viscose threads
IPC: D06M15/333
Filed: 1961-11-16
Abstract: One or more pre-stretched viscose threads are impregnated while stretched in polyvinyl alcohol solution, dried while still stretched, impregnated while stretched or under tension with a second impregnating agent comprising an alkaline dispersion of a synthetic resin and a rubber in water having a total solids content of at least 20% by weight, preferably at least 25% and then dried under tension.

Apparatus for detecting variations in the gear ratio between e. g. a worm 3, Fig. 1, and a toothed wheel 2 comprises a disc 4 mounted coaxially with the wheel and driven independently by a motor 7, carrying two series of magnetic marks or teeth co-operating with a fixed pick-up head 5 and a pick-up 6 rotating with the wheel 2. The number of marks in each series is equal to the transmission ratio of worm gear 2, 3. The signal from pickup 5 is fed through a synchro 8 attached to the worm 3 whereby the rotor signal has the same nominal frequency as the signal from pick-up 6, and a frequency comparison is made in a phasemeter, any differences being indicative of variations in gear ratio. In a modification, Fig. 3 (not shown), a further series of marks on disc 4 is associated with an additional fixed pick-up head, the number of marks in the further series being chosen so that after suitable mixing the synchro 8 is fed with signals at its normal operating frequency. In another embodiment, Fig. 6, the synchro 8 is replaced by a further disc 15 coaxial with worm 3 and driven by a motor 20, the disc 15 carrying four sets of marks associated with two fixed heads 16, 17 and two heads 18, 19 rotating with worm 3. The number of marks in each set is chosen so that by appropriate mixing, as shown in Fig. 7, two nominally equal frequency signals are obtained whose difference is the error in the gear ratio between worm 3 and gear-wheel 2. Facilities may be provided for eliminating the effects of eccentricity between disc 4 and wheel 2.
