Title: Blood pressure recorder
IPC: A61B5/021
Filed: 1971-07-23
Abstract: 1398087 Blood pressure recorders CAMBRIDGE SCIENTIFIC INSTRUMENTS Ltd 30 May 1972 [23 July 1971] 34767/71 Heading ASK A blood pressure recorder comprises an occluding cuff communicating with an inflation pump, and a cup for placing over an artery of the patient, the cup being connected via a flexible tube to a microphone the output of which is amplified and fed to a pressure recorder. The cuff also communicates via a tube 30 or 31 with a bellows 12 so that as the cuff is inflated the bellows expands and moves an endless tape 20 via a rack 22 and pinion 21 against a spring 14 so causing a pen 25, carried on one end of an arm 23 slidably pivoted on a rod 24, to traverse a recording chart Korotkoff sounds detected by the microphone during deflation of the cuff are applied to a solenoid 9 which lifts an armature from the other end of arm 23 so that the pen 25 records a track of dots on the chart. The response of the cup/microphone/ amplifier is such that the output at 100 Hz is about twice that at SOHz which is stated to help produce a clear demarcation of the diastolic pressure. The cuff and bellows are vented via the other of tubes 30, 31 which is connected to a capillary tube 16 variably restricted by a needle moved by the bellows 12 so that the rate of movement of the pen 25 is substantially constant during deflation of the cuff.

Title: Improvements in or relating to aldehydo compounds and methods of preparing the same
IPC: C07C69/67
Filed: 1947-12-31
Abstract: Aldehydes of the formula <FORM:0658413/IV (b)/1> where R is a substituted amino group from which the free amino group may be regenerated, R1 is CN or COOalk, and "alk" is an alkyl group of 1-4 carbon atoms, are obtained by treating a compound of the formula CHRR1.COOalk with an allyl halide in the presence of an alkaline catalyst to give CH2=CH-CH2-CRR1-COOalk, converting this into the ozonide by treatment with ozone, and reducing the ozonide by known methods.  The aldehydes may then be converted into their acetals.  R may be phthalimido, acylamino or diacylamino, e.g. acetamido, benzamido or benzene sulphonamido.  Details are given of the reaction between ethyl acetamido-malonate and allyl bromide in alcohol (to which sodium has been added) to give ethyl 2 - acetamido - 2 - carbethoxy - 4 - pentenoate.  This is ozonized and catalytically hydrogenated with palladium on charcoal to give beta-acetamido-beta-beta-di-carbethoxy-propionaldehyde which is isolated as its 2 : 4-dinitrophenylhydrazone.  Other reactants mentioned are allyl chloride, allyl iodide and ethyl acetamido-cyanacetate.  Amino-acids.-The aldehydes produced as above may be used in the synthesis of amino-acids as follows: The product of the example is (1) condensed with ethyl cyanacetate and hydrogenated to give CH3COHN-C(COOEt)2-CH2-CH2-CH(CN) -COOEt, which is hydrolysed to alpha-acetamido-delta-cyano-valeric acid; the latter is reduced to the delta-amino-methyl compound and hydrolysed to yield lysine; (2) converted into its cyanhydrin and dehydrated to give CH3CONH-C(COOEt)2-CH : CH-CN which is (a) hydrogenated and hydrolysed to glutatic acid; or (b) reduced to the saturated aminomethyl compound and hydrolysed to ornithine; (3) oxidized to the corresponding carboxylic acid and hydrolysed to aspartic acid; (4) condensed with phenylhydrazine and ring-closed to ethyl alpha-acetamido-alpha-carbethoxy-3-indolyl-acetate which is hydrolysed to alpha-amino-3-indolyl-acetic acid.  The Specification as open to inspection under Sect. 91 refers to the preparation by the above method of aldehydes CRR1R2-CH2-CHO, where R and R1 are hydrogen, carboxylic acid or ester, CONH2, CONHR or CN (but not both hydrogen), and R2 is substituted amino, e.g. methylamino, phenylamino and N-carbobenzoxy in addition to the groups specified above.  The esterifying group in the carboxyl group and the substituent in CONHR may be methyl, ethyl, propyl, phenyl, benzyl, toluyl or other hydrocarbon radicals.  These aldehydes may be converted into acetals, after which the group R may be converted to H by decarboxylation and the acetal then hydrolysed back to the aldehyde.  Similarly R in the acetal may be converted into an amide or nitrile group before hydrolysis.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1384106 Centrifugal moulding of fibre-reinforced concrete pipes AMEY ROADSTONE CORP Ltd 14 June 1973 [27 July 1972] 35184/72 Heading B5A [Also in Divisions F2 and E1] Glass fibre strand or roving 29 (Fig. 3) is ejected on to the inner surface of a rotating centrifugal mould 11 and is centrifugally embedded in cementitious material to form a pipe. The fibre is wound helically or wavy helically, continuously or discontinuously. Longitudinal strands or roving can be included. The mould 11 is rotated by chain-driven rollers enaging mould flanges. Spigots and sockets are defined by the mould 11. Glass-fibre feeder.-The feeder is mounted on a carriage travelling along rails. Roving 29 is taken from a bin 28 by electronically controlled, driven feed rollers 33. Compressed air is fed at 43 into an air mover 42 that feeds the roving 29 to an ejector head 46. Cement slurry from a supply 49 passes into the ejector head 46 through a filter 48, and surrounds the roving 29 after a nozzle plate 50. The ejector head 46 is mounted on a boom for entry into the mould 11. Cutter rollers 38 are moved together by a handle 41 for cutting of the roving 29 by a knife 39. (The cement slurry may be omitted if desired.) Operation.-The mould 11 is rotated and the ejector head 46 positioned in the mould. The alkaline resistant roving 29 is fed into the mould at a faster speed than the mould rotation, togethef with the cement slurry from supply 49, as the head 46 is moved to-and-fro along the mould 11 to produce several impregnated wavy helical windings. The roving and slurry feed is stopped, and a layer of concrete including crushed granite aggregate is applied with increased speed of mould rotation. The mould rotation is slowed again, and a further layer of roving (with or without slurry) is applied. The pipe bore is then lined with granite dust and cement, at a fast mould speed. Steam and air curing are applied. In an alternative embodiment, a pair of roving and slurry shells 68, 69 (Fig. 7) are produced centrifugally as above, and placed between support plates 70, 71. Concrete is cast and vibrated between the shells. The inner shell 69 can be replaced by a removable steel mandrel. Speeds, dimensions and materials are disclosed.

In Fig. 1 an oscillator C generates pulses whose frequency depends on the intensity of the flashlight reflected from the object B. The pulses are counted at D and when a preselected stage 8d has been reached the tube 1 is turned off by a series switch, a parallel switch or a Kerr cell. Preferably the counter stage is pre-selected according to the diaphragm aperture set. Figs. 2 to 7 (not shown) show various forms of the oscillator C. In (Fig. 3) a capacitor (16a, b, c) is selected according to film speed. In Fig. 11 oscillators O1, 02 . . . have different frequencies. Before exposure, one of the oscillators is manually selected according to the estimated distance of the object, a pre-exposure flash is fired and pulses from the selected oscillator are counted at 36 for a period determined by a light-sensitive timer 40. One of lamps L11 to L16 connected to counter 36 then lights up to indicate whether the distance has been correctly estimated. For instance, oscillators O1, 02 . . . may respectively correspond to object distances of 1m, 2m ... Lamp L11 will light up if oscillator O1 has correctly been selected, lamp L 12 if oscillator 02 has correctly been selected and so on. During exposure pulses from the selected oscillator O1, 02 . . . are frequency divided at 33 according to selected aperture, and counted at 36. When a pre-selected count is reached the tube 1 is turned off. Figs. 9, 10 and 13 (not shown) show similar arrangements. In (Fig. 9) the counter stage is selected according to film speed. In Figs. 14 to 17 (not shown) and Fig. 18 the selection of the oscillators is performed automatically by a light detecting circuit so as to control pulse frequency according to light reflected from the object i.e. according to object distance. Fig. 18 shows an arrangement for SLR cameras. Before exposure a preliminary flash is detected at Co to select an oscillator E and pulses from the sel-  ected oscillator are counted at 56 for a period determined by a timer T which may be set according to aperture or film speed. During exposure, pulses from a reference oscillator Ho are counted by a subtraction counter 78 and a coincidence detector 79 terminates the flash when counters 56 and 78 have identical counts, Figs. 19, 20, 22 (not shown) show SLR arrangements using the principles of Fig. 1.
