Abstract: 1,214,645. Determination of oxygen. W. WALISCH. 16 Sept., 1968 [26 Sept., 1967], No. 43854/67. Heading B1X. The oxygen content of an organic sample is determined by pyrolysing the sample and entraining the gaseous pyrolysis products in a stream of suitable carrier gas, passing the gas stream over a finelly divided mixture of nickel and carbon heated to such a temperature that the oxygen in the gaseous pyrolysis products is quantitatively converted to carbon monoxide, absorbing gases other than CO, inert gases, N 2 , H 2  and CH 4  from the gaseous stream, oxidising the CO to CO 2  without substantially affecting any CH 4  present and determining the amount of CO 2  present in the resulting gas stream. Carrier gas, e.g. helium +1 %H 2  is supplied at constant pressure from cylinder 10 by means of valves 11 and 12 and by means of the arrangement of valve 19, tube 20 and waterfilled vessel 21 the pressure of gas in the apparatus is kept constant. The sample in platinum boat 22 is inserted into the hot zone 17 of the pyrolytic tube 16 by means of a quartz rod 23 having a magnetic portion 25 associated with a further magnetic portion 26 outside tube 16. The gaseous pyrolysis products are carried by the carrier gas over the nickeled carbon charge 17 wherein oxygen is converted to CO, the resulting mixture being passed via line 27 to an absorption tube 28 containing layers of soda asbestos 28a, sodium thiosulphate 28b, soda asbestos 28c and magnesium perchlorate 28d. The 'remaining mixture of inert gases, CO, N 2 , H 2  and CH 4  passes on to oxidation tube 30 at 250‹C where the CO is oxidised to CO 2 , H 2  to H 2 O while CH 4  is unchanged and the water is retained in absorption tube 31 containing magnesium perchlorate. The CO 2 , N 2  and CH 4  in helium pass into the measuring cell 32 of a symmertical catharometer 33 wherein the CO 2  is absorbed in tube 35.

Title: Improvements in or relating to electric impulsing devices
Inventor: FAWLK PETER ALAN
IPC: H04M1/34
Filed: 1967-09-29
Abstract: 1,236,569. Impulse transmitters. GENERAL ELECTRIC CO. 30 Sept., 1968 [29 Sept., 1967], No. 44511/67. Heading H4K. A telephone dial impulsing mechanism has a pivoted trigger member 21 provided with two fingers 27, 28. On setting of shaped impulse wheel 13, by means of the finger plate (not shown) to which it is attached, to a position representative of a particular digit to be impulsed, the member 21 is caused to rotate clockwise, the finger 28 being carried round and riding over at least one of the teeth 14 of wheel 13. During setting of the wheel 13 in the direction of arrow 49 to the digit required, the member 21 is prevented from excessive rotation by a leaf spring 25 abutting against projection 53. Also during this rotation there is no effect on impulsing the contacts 32, 33, carried by leaf springs 29, 30, which remain closed. During return of the wheel 13 to its normal position, the finger 28 is dragged round to rotate the member 21 anticlockwise and finger 27 is caused to ride up, at least once, over a tooth 14, during which time, the projection 38 on this finger causes spring 30 to be lifted and break the contact between 32 and 33, this being made again as the finger rides down into the next notch, this lowering being caused by spring 25 bearing on the flat face 51 of member 21. Co-operating in re-closing the contacts 30, 32 is a ramp 37 on an angular projection 35 of wheel 13, which urges spring 29 upwards. Wheel 13 is cut away at 52 so that the finger 27 does not ride up again to cause another impulse. The required period of lost motion is provided by the interval during which the member 21 is pivoted round to a position where finger 27 starts to ride up on a tooth 14. Pairs of offnormal contacts 40, 41 and 46, 47 are opened by ramps on annular projections 35, 48 of the wheel 13. The springs are of, e.g. phosphor bronze, and the trigger member 21 and the wheel 13 of moulded formaldehyde acetal resin. The spring 29 may be omitted, being replaced by an elongated tail portion of member 21 which abuts against respective stops projecting from the dial base-plate to prevent excessive rotation of the member 21.

Title: Improvements in or relating to a method of forming garment patterns of graded sizes from a block pattern
IPC: A41H3/00
Filed: 1961-12-12
Abstract: 955,868. Garment patterns. N. L. RAWLINGS. Dec. 12, 1962 [Dec. 12, 1961], No. 44539/61. Heading A3V. The invention comprises a transparent block pattern and a method of forming a graded garment pattern from such transparent block pattern. The method comprises marking two mutually inclined lines on a surface on which the garment pattern is to be formed, thereby defining datum lines, placing a transparent block pattern on the surface, bringing two reference lines on the block pattern into coincidence with the two datum lines, moving the block pattern through predetermined distances along the datum lines to position the block pattern in successive different spaced relationships to the datum lines so as successively to establish the position of key points of the graded pattern and connecting the key points on the surface to provide on the sheet the graded pattern. The block pattern has bevelled edges 12, and is made of semirigid transparent plastics. Reference lines, a bust line 32 and grain line 31 are marked on the block pattern and a grid of spaced lines is marked parallel to the reference lines defining a scale with which to measure the successive different positions of the block. To mark out a pattern the block pattern is placed on the material on which the pattern is to be marked so that the datum lines coincide with the reference lines 31, 32 of the pattern block. The periphery of the block pattern is then marked on the material. To vary the size of the pattern the block pattern is moved in successive steps with different components of the grid coinciding with the datum lines and the pattern traced in steps. To make a pattern a size larger, the bust line 32 is placed # inch above the corresponding datum line and the centre line 13, neck point 14, and lower part of the neck are traced. The block pattern is moved so that line 36a coincides with the datum line. The neck point 16 and the neck line are drawn. Line 39a is then placed on the corresponding datum line, shoulder point 18, upper part of armhole and the shoulder line are drawn. The bust line 32 is then placed on the corresponding datum line and the lower arm point 20 and the armhole are drawn. The grid line 37a is then placed on the corresponding datum line and the top of the underarm is traced. The bust line 32 is placed # inch below corresponding datum line and the side line 21 and part of the waist line is drawn. The centre line 13 is moved # inch to the left of the centre line on the material and the waist line is drawn. The bust line 32 is brought into coincidence with the corresponding datum line and waist dart point 30 is marked. The block is removed and the pattern completed marking dart lines from point 30 to notches 28 and 28a. Block patterns are similarly constructed for skirts and sleeves.

[Also in Division B5] A blank, formed by a pair of superimposed sheets of which one sheet 8 is coated with patterns 12 and 13 of stopweld material, is rolled to selectively pressure weld the sheets together, fluid pressure is introduced into pattern 12 to expand the pattern and form a seal between the blank and a pair of supporting platens 24, 25, and the pattern 13 is then expanded. To control the expansion of the pattern 13 a relatively low fluid pressure is introduced into the space 26, the pressure causing the lower surface of the blank to remain flat after expansion of the pattern 13 or to distend outwards slightly. The pattern 12 is subsequently cut off and discarded. A constriction 15 between the two patterns is designed to open when the fluid pressure delivered at 10 reaches a predetermined value. Alternatively the patterns 12 and 13 can be provided with separate inlets (Fig. 4, not shown) extending to the edge 11 of the sheet 8, a rubber seal extending between the ends of the pattern 12. The two sheets may be of metal or plastics material, with one metal and one plastics sheet, if desired.

Abstract: 1,240,488. Electro-medical apparatus. INTERNATIONAL BUSINESS MACHINES CORP. Sept.26, 1968 [Oct.24, 1967], No.45668/68. Heading G1N. To detect significant portions of an electrocardiogram, an electro-encephelogram or other complex waveform a signal derived from the waveform, e.g. by differentiation, is applied to a threshold circuit the threshold level of which is increased each time it is exceeded by the signal and thereafter allowed to diminish towards a minimum value. The threshold circuit triggers a waveform sampler which may be coupled to a recorder so that the significant portions of the waveform are recorded. The provision of a variable threshold level ensures that the system will record a small pulse occurring after a quiet interval whilst not responding to every noise pulse in a noisy part of the signal. In Fig. 1 the differentiated waveform is supplied via a filter 17, which eliminates h.f. noise, to separate positive and negative low-level threshold circuits 31, 33. The level at which each of these responds is determined by the voltage on capacitor C1. If either level is exceeded the corresponding threshold circuit provides an output pulse and also operates a monostable 35 or 37 to add a fixed amount of charge to the capacitor. Other fixedlevel threshold circuits may be provided, as 19, 21, which respond only to large deviations of the differentiated waveform from zero and instruct the sampler to record the corresponding portion of the waveform in detail.
