Title: Automatic cuff mechanism for blood pressure measuring system
IPC: A61B5/022
Filed: 1975-09-08
Abstract: 1476851 Sphygmomanometers MEDICAL MONITORS INC 8 Sept 1975 [9 Sept 1974] 36815/75 Heading A5K A cuff mechanism for use with a blood pressure measuring system comprises a hollow cylindrical member 10 housing a circumferentially extending flexible band 21 which is attached at one end to the cylindrical member 10 at securement points 22 and a cable 23 secured to the band 21 adjacent securement points 22 and extending circumferentially between band 21 and cylindrical member 10 to pass through an extension housing and connect to a drum 34, and a flexible fluid chamber 24 lying on the interior surface of the band 21 for engagement with the human arm. In use, initiation of the system operates a solenoid 42 to engage motor 38 to drive drum 34 to pull the cable 23 and engage the band 21 with the arm (as shown at 21<SP>1</SP>) to exert pressure determined by the torque of the motor 38, fluid is then pumped into chamber 24 by a pump 27 via a valve 26 until the detection of acoustic pulses by microphone 32 from acoustic chamber 30 via passage 31 operates to close valve 26 at the systolic pressure and open a valve 29 to reduce the pressure in chamber 24 until the diostolic pressure is measured, the solenoid 42 will then be deactivated to release the cable 23 from the drive, thereby allowing release of the patients arm. The cuff is mounted on the proximal end of a base plate, on which is also mounted a forearm rest which is slidable relative to the cuff for adjustment for different patients. Instead of having a closed cylindrical member 10, an openable, clam-like member may be provided.

Title: Improvements in and relating to the refinement of magnetic metals and alloys
IPC: C22B9/05
Filed: 1930-12-06
Abstract: 368,780. Refining magnetic metals and alloys. SMITH, W. S., Benchams, Newton Poppleford, Devon, GARNETT, H. J., Lymne, Solefields, Sevenoaks, Kent, and RANDALL, W. F., Stretton, Queensmead Avenue, Ewell, Surrey. Dec. 6, 1930, No. 36869. [Classes 72 and 82 (i).] Magnetic metals or alloys particularly iron, nickel, and their alloys are refined by subjecting the molten metal or alloy in a closed container to the action of a predeter. mined amount of oxygen or oxygen containing body in conjunction with a blast of inert gas, the gaseous products of the oxidation being withdrawn under reduced pressure. Preferably a gas such as nitrogen containing oxygen is employed, or substance for example nickel oxide or iron oxide is suspended in the gas and blown into the metal by an injector. Alternatively the oxidizer may be added separately to the bath which may be subjected to the blast of inert gas. The metal may be melted in a furnace comprising a hermetically sealed crucible a heated by an induction coil b and provided with a mica window d, a tuyere e, and an outlet g coupled to a suction pump. Alternatively, gas tuyeres may be situated in the side walls of the crucible above the normal level of the metal, the furnace being tiltable so as to bring the metal over the inlet tuyeres. When oxygen is present in the original material it will be moved by interaction with any carbon present during the initial melting in vacuo and this oxygen is allowed for in determining the quantity of oxygen to be passed through the metal. Excess oxygen is removed by sucking carbon monoxide (mixed if desired with an inert gas) through the metal.

Title: Pneumatic timer attachment for type m relay
IPC: H01H43/28
Filed: 1971-08-06
Abstract: 1407674 Electromagnetic relays; retractive switches SQUARE D CO 4 Aug 1972 [6 Aug 1971] 36977/71 Heading H1N [Also in Division F2] An adjustable delay between the manual (Fig. 11) or electromagnetic (Fig. 8) actuation and the operation of contacts 135, 136, 138 of a snap-action switch is provided by the restricted flow of air into the diaphragm bounded chamber 96, Fig. 3, of a pneumatic timer (for detailed operation see Division F2). The movable contacts 138 of the snap-action switch are carried by a contact bridge 140 slidably mounted on a contact carrier 132 by two toggle springs 148, 150 inserted in indentations 144 forming a fulcrum 142. When, on movement of the contact carrier 132, the fulcrum 142 is shifted from one side of the bridge 140 to the other, the movable contacts 138 shift from one pair of fixed contacts to the other. Upward movement of the contact carrier 132 is effected by a push-button 285, Fig. 11 or by the de-energization of an electromagnetic relay 250, Fig. 8, When the relay is de-energized, the armature 258 and relay contact carrier 48 (also in Fig. 1, not shown) are urged upwardly by springs (not shown). This causes a rocker 14 to rotate clockwise and engage the offset foot 154 of the contact carrier 132, to move it upwards. Toggle springs 148, 150 are moved over centre, and the movable contacts 138 move from the upper to the lower pair of fixed contacts. At the same time the upward movement of the contact carrier moves a rod 109 upwardly against a spring 122, and a valve opens to exhaust the timing chamber 96. The timer is now set for the timing stroke. This is initiated by releasing the push-putton, Fig. 11 or energizing the relay 250. The armature 258 is attracted to the core 256 and the armature 258 and relay contact carrier 48 are moved rapidly downwardly away from the contact carrier 132, and the rocker 14 rotates anti-clockwise away from the carrier. The carrier 132 is urged downwardly by the spring 122 against the bias of the toggle springs 148, 150. This downward movement, which will open the lower contacts and close the upper contacts, is delayed by the rate at which air can enter the chamber 96 from the atmosphere. To provide instead a time delay between de-energization of the relay 250 and operation of the snap-action switch, the timer/switch attachment (Fig. 3) is removed from the relay 250 and rotated through 180 degrees so that the offset foot 154 of the contact carrier 132 projects in the opposite direction (Fig. 10, not shown). A screwdriver slot in the rocker 14 allows manual actuation to test the timer and snap-action switch without energizing or de-energizing the relay 250.

Title: Heat-treated compositions of butyl rubber and alkenylhalosilane-modified mineral fillers
IPC: C08K9/06
Filed: 1956-12-04
Abstract: Butyl rubber compositions of improved tensile strength, modulus, and elasticity characteristics are prepared by mixing a mineral filler reacted with alkenyl-halosilane, with the butyl rubber, heat-treating the resulting compositions in the absence of curing amounts of vulcanizing agents, and masticating the heat-treated composition. Copolymers of monoolefines with multi-olefines with a molecular weight of from 20,000 to 100,000, a Mooney value of 30 to 90 and iodine number of 0.5 to 50, such as isobutylene-isoprene are used and the fillers may be natural or synthetic, e.g. partially hydrated silicas, aluminas, silicates, clays, carbonates, and titanium dioxide.  The alkenyl halosilanes may have the general formula RmSinX2n + 2-m where R is a straight or branched chain alkenyl group, such as vinyl, alkyl, butenyl, hexenyl or octadecenyl, and X is a halogen, m is 1 to 2n+1 and n is 1 to 5.  The filler may be modified by treating for example with a paraffin solution of the alkenylhalosilane, warming, evaporating the solvent and drying.  The heat treatment may be carried out by hot milling or by static heating, followed by mastication.  In a modification a small amount from 0.05 to 10 per cent of a heat interaction promotor, such as p-quinone dioxime, or its esters or derivatives, p-dinitroso benzene, and quinone imines and their esters may be present during the heat treatment.  After the final mastication the composition is cooled and then may be cured with the usual curing and compounding agents and extruded or moulded to shaped articles or used in a volatile solvent as a cement.

Abstract: 368,720. Coin-freed weighing-apparatus. TRIPODI, G. and GARAVENTA, F., Banco Cambio Cobianchi, Piazza Duomo, Milan, Italy. Dec. 8, 1930, No. 37031. [Classes 27 and 143.] The coin-freed weighing-apparatus described in Specification 296,672, [Class 27, Coin-freed apparatus &c.], is provided with devices for making an announcement additional to that of the weight of the person being weighed. The rotary shaft 16, described in the prior Specification, carries a cam disc 71 which rocks a lever 4 to release, through a link 7, a catch 11 from a catch 12 on a lever 13 which tilts and closes contacts 15, 17 in the circuit of an electric motor 19. The motor drives a turntable 24 carrying a record 25 engaged by the stylus 26 of a soundbox 27 or an electrical pick-up, the record bearing the additional announcement. The motor also drives a wheel 29 having on its underside a cam 30 for opening the contacts 15, 17. A brake lever 32 to stop the turntable is actuated by an eccentric 33 rotating with the gear wheel 29. At a predetermined point in the travel of the stylus towards the centre of the record, a member 36 sliding on a guide 37 engages the end 38 of a lever 39 to rock this and release an arm 42a fixed to a shaft 43 which is then rotated under the action of a weighted arm 44 to raise a link 45 and members 46 which support a follower 47 connected to the sound box 27, thereby raising the stylus from the record. A member 48 carrying the follower 47 is then engaged by the end 42 of the arm 42a and pushed back to its starting point. When the motor starts, a cam 49 on the wheel 29 raises a rod 51 to rock a lever 52 which resets or raises the weight 44 and causes the end 42 of the arm 42a to engage a tooth 41 on the lever 39. A dashpot 54 cushions the fall of the weight 44.

Title: Method of mercerising cellulosic textile materials
IPC: D06M11/38
Filed: 1973-08-04
Abstract: 1485756 Mercerizing cellulosic textiles MATHER & PLATT Ltd 29 July 1974 [4 Aug 1973] 37107/73 Heading D1P Cellulosic textile materials are mercerised by saturation with an alkaline swelling agent at a concentration of at least 8.75% by weight and at a temperature of at least 50‹C, for an immersion time of 60 seconds or less, and squeezing excess treatment liquor from the material. The material, after being fed through the mercerising solution, is delivered to a draw nip device under controlled conditions of tension in the length and/or width directions, during a reaction time in excess of one second, after which the material is washed under conditions of controlled tension and of relaxation respectively. The saturation step is preferably tensionless. Between squeezing and the draw nip device the material may be subjected to a treatment with steam (saturated and/or superheated, at or above atmospheric pressure) or with a wash liquid above 50‹C, the reaction time thus being extended to up  to 10 minutes. The process is preferably applied to loomstate material and may include over-stretching in the warp and/or weft directions to provide optimum tensile strength and subsequent dimensional stability. It may be used in conjunction with a high pressure hydrogen peroxide bleach, a pre-bleach scour being unnecessary. The material treated may be in the form of woven or knitted fabric, non- woven fabric or yarn, the latter being either wound in hank form or in the form of a ribbon or rope of continuous threads, and may comprise cotton, optionally blended with polyester. Apparatus for carrying out the process is shown in Fig. 2, wherein a fabric F is overfed from an entry nip 11 sinuously through a caustic soda tank 10 via driven rolls 12 to a heavy mangle squeeze nip 13 and thence via an extended reaction time chamber 17 for steam or liquid treatment and through which the fabric F is conducted in an elongate sinuous path over rollers 18, to a draw nip 14, the fabric being stretched between the nips 13 and 14. After the draw nip 14 is a widthcontrolled chain or chainless washer 15 followed by a multi-loop washer 16. In a modification for treatment with steam at superatmospheric pressure, the chamber 17 is replaced by a chamber (20) Fig. 3 (not shown) with entry and exit seals (21) and (22). Alternatively, the chambers may be omitted and the fabric passed directly from the nip 13 to the draw nip 14. The nips 11, 13 and 14 are driven by a positive infinitely variable drive to indicate percentage loss/gain in fabric length. Automatic level and temperature controls are provided for the tank 10.

Abstract: 1,192,259. Seaming non-metallic sheet material. LISTAFLOOR A.G. 5 Aug., 1968 [5 April, 1968], No. 37255/68. Heading B5K. Two pieces of carpet 14 with their backing on a supporting base are joined continuously by means of a device which has an elongated hollow body 1, open at top and bottom, whose tapered end 5 progressively turns up the seam edges of the carpets as the device is moved in the direction of the arrow 17. The body 1 has downwardly flared walls, at least in its central zone, which hold the carpet in the turned-up position as an adhesive tape 22, folded lengthwise, is progressively inserted into the gap underneath the seam line. The tape is guided by the guide wheel 7 and laid flat. The edges of the carpet are reunited, as they pass over the tapered end 12 of the body 1, by means of the wheels 15 and roller 21 so that they are laid down again and bonded to the tape. The tape is advantageously a potentially adhesive one which is rendered adhesive by the application of heat e.g. by blowing hot air over it from a blower 27 or by using the underside of the end 12 as a heater surface.

Title: Antibiotic complex 1415 and process of producing it
Filed: 1960-11-02
Abstract: A new antibiotic complex designated antibiotic 1415, having 8 constituents is produced by cultivating Streptomyces strain 1415 or an antibiotic complex 1415-producing mutant <PICT:0917464/IV (b)/1> <PICT:0917464/IV (b)/2> thereof under aerobic conditions in an aqueous nutritive substrate containing sources of assimilabe carbon, nitrogen and inorganic salts, preferably at a temperature of 20 DEG -35 DEG C. e.g. 27 DEG C.  A specified nutritive substrate comprises peptone, Liebig's meat extract, corn steep liquor, glucose and sodium chloride.  The antibiotic complex is isolated by (a) extracting the clarified broth with a water immiscible organic solvent e.g. ethylacetate and the mycelium with a water miscible organic solvent e.g. acetone or a water-immiscible organic solvent or (b) by adsorbtion of the antibiotic complex from the whole broth on to an adsorbent e.g. activated carbon and subsequently eluting with an organic solvent, other than petroleum ether, gasoline, and ligroin e.g. acetone or benzene.  The antibiotic complex is purified by chromatography on adsorbents such as carbon, silicon dioxide, aluminium oxide or "Celite" (Registered Trade Mark) saturated with a proper stationary phase.  The antibiotic complex is precipitated from solution by a non-solvent e.g. petroleum ether, gasoline, ligroin or water.  Purified antibiotic complex 1415 is a white solid which is active against gram-positive bacteria e.g. Bacillus subtilis or Staphylococcus aureus.  On acid hydrolysis it gives glycine, alanine, proline, valine, phenylalanine, leucine and an unidentified amino-butyric acid.  It softens at 90 DEG -95 DEG C., has a specific rotation [a ]20D = -34 DEG  51 (1% in methanol), contains C = 59.44-59.57%; H = 7.98-8.04% and N = 2.04%, has U.V. and I.R. spectra as shown in Figs. 5 and 6 respectively and gives a negative nenhydrin reaction.

Title: Temperature control circuits
IPC: G05D23/24
Filed: 1972-08-16
Abstract: 1433480 Automatic control of temperature ADCOLA PRODUCTS Ltd 28 Aug 1973 [16 Aug 1972] 38239/72 Heading G3R A temperature control circuit e.g. for a soldering iron, comprises a temperature sensor 13 and a desired temperature setter R 15 which together with R 14 form a potential divider between lines 8 and 10, which divider controls a transistor 17 in dependence upon the relationship of the sensed temperature to the desired temperature. At the beginning of each half-cycle of a rectified A.C. supply the potential at a point A rises to a level at which the transistor 17 conducts to produce a firing pulse for a switch device SCS 16. When the transistor 17 saturates the potential at A drops to zero and the pulse terminates. Thereby SCS 16 is caused to fire an SCR6 of supply 2 to energize a  heating element 7 when the sensed temperature is below the desired temperature. To prevent the firing of SCR6 as the supply voltage decreases toward the end of each half-cycle, a negative pulse is produced at this time by a differentiating circuit C21, R22 which causes a transistor 20 to saturate thus holding down the potential at the point A and ensuring that SCS16 cannot be switched on. When the supply voltage is rising at the beginning of each half-cycle the differentiating circuit produces a positive pulse which cuts off transistor 20 and allows the potential at A to be determined by transistor 17 in dependence upon the sensed and required temperatures. R25, C24 functions to increase the length of firing pulse applied to SCS 16 by slowing the rate of voltage rise between lines 8 and 10. A resistor 26 produces a noise signal at the gate electrode of  SCS 16 which signal increases the effective amplitude of the firing pulse and ensures that SCS16 conducts during each half-cycle as required.
