Title: Improvements in or relating to the production of seam-like connections between flat fabric members by means of thermoplastic materials
Inventor: KELLER SIEGFRIED
IPC: D06M17/00
Filed: 1959-11-18
Abstract: 898,082. Seaming non-metallic sheet material. MESSERSCHMITT A.G. Nov. 18, 1958, No. 36986/58. Class 42 (1). A process for producing seam-like connections in flat fabric structures, using thermoplastic masses applied to the structures and which are liquefied, is characterized by the use of thermoplastic plugs for forming a point-to-point seamlike connection between two or more webs. In one embodiment, Fig. 1a, balls 3 of thermoplastic resin bonding agent, fed from a magazine 4, are pressed by a pin 2 into holes 8, previously formed, in two layers 5, 6 of fabric. The fabric layers are fed stepwise by a plate 7 similar to the needle plate of a sewing-machine to provide a seam-like row of bonding points. Pin 2 and a plate 9 supply heat by conduction, ultrasonic energy or high-frequency electric energy to melt the bonding agent. In one modification, balls of bonding agent are pressed into the fabric from opposite sides simultaneously, no perforations being previously formed. In a second modification, the bonding agent is in the form of tapered studs which are driven into the layers of fabric ; the studs may be preformed or may be nipped off a wire at the time of insertion.

Title: Production of benzofurans
Inventor: GRAHAM ARCHIBALD ROBERT
IPC: C07D307/79
Filed: 1958-11-20
Abstract: The invention comprises 2,3-dipropylbenzofuran and a process for making benzofurans in general by condensing an aliphatic a -hydroxy carbonyl compound with a phenol.  The aliphatic a -hydroxy carbonyl compounds are compounds having the formula <FORM:0858470/IV(b)/1> in which R1 and R2 are hydrogen or alkyl groups preferably containing up to 6 carbon atoms.  The preferred compounds are hydroxyacetone, acetoin and butyroin.  Preferred phenols are phenol itself, resorcinol, naphthol, alkylphenols, nitrophenols and ethers of polyhydric phenols containing at least one free hydroxy group.  The reaction is preferably carried out between 100 DEG  and 400 DEG  C. Solvents, e.g., paraffins, cumene, xylene, chlorbenzene, dioxane and anisole, may be used for a reaction carried out in the liquid phase and inert diluents such as nitrogen, carbon dioxide or the vapour of any of the above-mentioned solvents may be used in a vapour phase process. If desired, a condensation catalyst, such as activated alumina, acid- or alkali-treated pumice, ion-exchange resins, mineral acids especially in the presence of iron, fullers' earth, betonite, Florida earth and attapulgite, may be used.  In examples: (a) phenol is condensed with hydroxy-acetone to give 2-methylbenzofuran; (b) phenol is condensed with acetyl methyl carbinol (acetoin) to give 2.3-dimethylbenzofuran; (c) phenol is condensed with butyryl propyl carbinol (butyroin) to give 2.3-dipropylbenzofuran; (d) resorcinol is condensed with hydroxyacetone to give 2-methyl-4-hydroxybenzofuran; and (e) b -naphthol is condensed with hydroxyacetone to give 2-methyl-4.5-benzoumarone.

Title: An electromagnetic open-circuit spirograph
IPC: A61B5/087
Filed: 1959-11-04
Abstract: 881,444. Spirographs. VYZKUMNY A ZKUSEBNI LETECKY USTAV. Nov. 4, 1959 [Nov. 5, 1958], No. 37416/59. Class 81 (2). [Also in Group XXXVIII] A spirograph for recording inhaled and exhaled breaths without the use of a closed circuit of air or oxygen comprises a diaphragm pressure gauge attached by a lever to a body of magnetic material provided with a torsional energizing coil and a coaxial pick-up coil, the signal from the latter operating a recorder via an amplifier and servo-motor. In the Figure air is inhaled at A and exhaled at B, thus causing alternating differences of pressure in the tubes 23 and 24, which communicate with opposite sides of a diaphragm 4. Movement of the latter is passed by a lever 5 to twist one end of a body 7 of magnetic material, the other end of which is fixed. An A.C.-fed toroidal winding 9 then produces an output in a coaxial winding 8 of magnitude and phase sense corresponding to the pressure difference between 23 and 24. This signal is passed to an amplifier 10 which has a non-linear resistor 11 in a feedback loop so that the output will be proportional to the square root of the input and hence to the rate of flow of air past the orifices 23 and 24. This output energizes a two-phase servomotor 13 which moves a carriage 16 along rails 18 and makes a permanent record on a tape 20.

Title: Improvements in shock absorbers or vibration dampers and the like
IPC: F16F9/26
Filed: 1929-12-10
Abstract: 343,229. Pneumatic and hydraulic shock-absorbers. RULE, T. B., 45, Belgrave Road, New Moston, near Manchester. Dec. 10, 1929, No. 37808. [Class 108 (iii).] A differential piston works in two opposed coaxial cylinders of different diameter, the smaller cylinder being connected to an air chamber which provides an elastic cushioning effect in addition to the throttling effect due to the flow of liquid through restricted orifices. The differential piston d is reciprocated by an arm c on the operating spindle b and the left end is of slightly larger diameter than the right end. The right-hand cylinder communicates with the air reservoir l through an opening j, the effective area of which may be regulated by a valve k adjustable from the outside. The left end of the piston is provided with serrations v through which liquid may flow when the piston moves to the left, the serrations being covered, when the piston moves to the right, by a ring-shaped valve e urged towards its seat by a coiled spring f. A passage running right through the piston is partly closed as required by the screw h. When the piston moves towards the left and covers the small radial connection c to the central reservoir, liquid flows from the lefthand cylinder through the serrations b, past the valve e, through radial holes g into the central passages and thence to the right-hand cylinder, the air in the reservoir l being thereby compressed. When the piston moves to the right the valve e returns to its seat and covers the serrations so that liquid can only flow to the left-hand cylinder, past the valve h and through the radial holes i. The action described above applies only to rapid movements of the piston since the passage c quickly brings about equalization of the pressures in the two cylinders as soon as it is uncovered by the return of the piston. In a modification the screw h may be adjusted without removing the cup u.

Title: Stabilizing system
IPC: F41G5/16
Filed: 1973-08-09
Abstract: 1442822 Automatic control of attitude PNEUMO DYNAMICS CORP 9 Aug 1973 [28 Sept 1972] 37832/73 Heading G3R A member mounted on a movable structure (a gun on a tank) is stabilized in at least one plane by a motor controlled in response to signals from rate gyros on the member and structure respectively, the output of that on the member being integrated. In the embodiment, stabilization is in elevation and azimuth by similar systems, one version of which is shown in Fig. 2. The motor is hydraulic and its speed is controlled by the position of a servovalve 32, the control signal 31 for which comprises the sum of a gun position signal 29 obtained by integrating at 28 the output of the rate gyro 27 on the gun, a rate of change (or velocity) signal 44 obtained from a servovalve displacement transducer 34 (which displacement is proportional to servomotor speed), and an acceleration signal 42 obtained by differentiating the output of a tachogenerator 36 driven by the servomotor. To improve the response of the system a signal from the rate gyro 39 on the tank is subtracted from the tacho signal at 38; thus, when the gun is driven moving equally and oppositely to the tank motion the output of 38 is zero. This difference signal is also added as a velocity term at 26. Desired movements (gun laying) are effected by adding the signal from a manually operated command rate potentiometer 24 at 25 and 26. Alternatively, the stabilizing system may be switched out and manual movements used to control the hydraulic valves directly Fig. 4, (not shown). To correct for drift in the system, i.e. movement when none is required, due to integrator offset &c., a potentiometer 46 is temporarily coupled to the motor by a manually controlled solenoid clutch; drift during this time results in a signal from 46 which is then permanently added to the control signal in a cancelling sense. In Fig. 3 (not shown) a complete elevation and azimuth system is shown; they differ from Fig. 2 in that the drift signal is combined with the gun gyro signal before integration.

Title: Power unit comprising a supercharged internal combustion engine
IPC: F02B3/06
Filed: 1975-09-17
Abstract: 1518348 Supercharged IC engines; centrifugal compressors; gas turbine plant FRANCE ARMED FORCES MINISTER OF 17 Sept 1975 [24 April 1975] 38273/75 Addition to 1429493 Headings F1B, F1C and F1G The Specification describes devices for actuating the automatically controlled throttle means which are a feature of the invention claimed in Claim 1 of the Parent Specification 1429493. By-pass conduit 22 which leads from the compressor outlet to the turbine inlet contains an air-balanced butterfly-type throttle valve 24, the actuating arm 25 of which is connected to the piston rod 28 of an assembly comprising small diameter piston 27, subject on one side to pressure P 2  and large diameter piston 26 subject on one side to pressure P 3 . Chamber 31 between the pistons is vented to atmosphere and the assembly is biased by spring 32. The device operates to produce a pressure drop across valve 24 which is linearly related to the pressure upstream of valve 24. In a first modification, Fig. 5, chamber 31a is connected directly to conduit 22 and chamber 30a is connected to the conduit via fixed restrictor 33 and to atmosphere through variable restrictor 34, 35 the position of which depends on the pressure P 2  in capsule 36. In a second modification, Fig. 7, the large and small piston assembly controls the position of valve member 37 which controls the rate at which hydraulic fluid, supplied by pump 40, leaks back to a fluid reservoir and thus controls the fluidpressure acting on piston 41 which actuates valve 24b. In a third modification, Fig. 8, pressure transducers 47, 48, provide signals proportional to pressures P 2 , P 3  which are fed to preamplifiers 49, 50 and then to differential amplifier 45 which energizes a stepping motor 46 to actuate valve 24c. In a fourth modification, Fig. 9, the position of valve 24d varies in dependence on the pressure upstream or downstream of the valve and on a second variable representing the ratio between the flow-rate in conduit 22d and the total flow delivered by the compressor. Pressure in the conduit is communicated to capsule 53 which moves the slider of potentiometer 54 and flow-rate is determined by Pitot tube 55 which communicates with capsule 56 and moves the slider of potentiometer 57. Each potentiometer is connected through an amplifier to an analogue multiplying circuit 60. Reversible actuator 61 drives both valve 24d and the slider of potentiometer 63 which is connected to amplifier 65. The outputs of amplifier 65 and multiplier 60 are connected to differential amplifier 66 the output of which is connected to actuator 61.

Abstract: 845,293. Infra-red analysis. STANDARD TELEPHONES & CABLES Ltd. Dec. 14, 1956 [Dec. 19, 1955], No. 38292/56. Class 40(3). A method of analysis comprises (1) determining the constituents of the mixture (2) preparing a synthetic sample containing the constituents and (3) determining, by measuring the infra-red energy transmitted through (a) the synthetic sample and samples of the constituents and (b) the mixture and the sample, the ratio of the constituents in the mixture. A continuous process 52 is fed with constituents through pipes 53, 54, 55. Pump 57 feeds a continuous analysis sample into cells 58, 60. Infra-red energy from a source 61 is detected at 65-67 after passing through the sample and sample cells 62-64 containing comparison samples of the constituents. The output of the detectors is fed to a computor 68 which is also fed by the subtractor circuits 69-77. The computor output, which is an error voltage for each of the constituents, controls through a servo motor 78 the valves of the pipes 53-55. The subtractor circuits are first calibrated with a set of co-efficients characteristic of the mixture masked by each of the constituents. The coefficients are determined by other equipment which may involve either placing the sample cells in tandem (Fig. 2, not shown) or by surrounding the infra-red source with one fixed and one movable turret of cells (Fig. 3, not shown). Alternatively the analysis may be carried out by (1) measuring the absorption of the mixture masked in turn by each of the constituents (as determined by initial quantitive analysis) (2) measuring the absorption of a synthetic sample masked by each of the constituents and (3) measuring the absorption of sample constituents with a shift in concentration in each sample as masked by each of the constituents. The results are used as a set of co-efficients in a system of simultaneous equations. Specification 845,292 is referred to.
