Title: Method of blowing-up air raid shelters and the like buildings
IPC: F42D3/00
Filed: 1946-04-11
Abstract: 624,771. Demolishing buildings. JESPERSEN, A. H. C., and JESPERSON, P. KERRN-, (trading as JESPERSEN & SON, A.). April 11, 1946, Nos. 11177 and 11178. Convention dates, Nov. 7, 1945 and Dec. 20, 1945. [Class 68 (i)] In the demolition of an air-raid shelter or 'like building enclosing a relatively large cavity, an explosive charge is laid in the building, or in an enclosed space communicating with the interior of the building, and connected to a remote exploding means, apertures in the building are securely plugged, the building is filled with water so as effectively to submerge the charge, and the charge is fired to demolish the building to which the shock of the explosion is transmitted through the water. The water-filling hole may be a fresh one, or it may be left during plugging, and after firing it may be plugged or left open. The water may be charged with peat-dust, saw-dust or like materials which tend to choke any leakage cracks in the building. The charge may be enclosed in a vessel of expansible volume, e.g. a cylinder with a loose piston, the cylinder being completely immersed in the water or disposed partly outside the building to form an extension of the cavity. The cylinder may be directed downardly, it may be formed with one or more small gas-leakage apertures, and it may have a stop to limit the movement of this piston. The building may be covered in earth or sand before the charge is ignited. The Specification as open to inspection under Sect. 91 states also that the cavity may be empty of, or only partially filled with a liquid such as water, or i,t may be filled with combustible or explosive gas, such as oxy-hydrogen gas mixture or acetylene, which may be compressed before firing, and that the space enclosing the charge may be wholly outside the building. This subject-matter does not appear in the Specification as accepted.

Patent GB-454963-A (GB)
Title: Improvements in or relating to the manufacture of glues, pastes and like adhesives
IPC: C08B31/08
Filed: 1935-04-11
Abstract: Glues, pastes, adhesives, and like materials are obtained by treating starch or other similar carbohydrates, with or without gelatinization, with certain etherifying agents in the presence of alkali, the quantity of etherifying agent employed being from 0,02 to 0,75 mol per mol of C6H10O5.  All carbohydrates, other than cellulose, of the type (C6H10O5)n, for instance maize, potato, corn, cassava, wheat, and rice starches, starchy fruits, starch flours, soluble starch, amorphous and crystallized starch (amylo-dextrin), a - and b -amylan, dextrins, inulin, geloses, and hydrolyzed and oxidized starches such as British gum, may be used as initial materials to be etherified, and the etherifying agents may be esters and mixed ester salts of inorganic acids, halogensubstituted aliphatic acids and their alkali salts, or cyclic olefine oxides and chlorhydrins of the type of cyclohexene oxide and chlorhydrin.  For instance, dimethyl sulphate, sodium methyl sulphate, methyl chloride, allyl chloride, crotyl chloride, ethyl chloride, sodium ethyl sulphate, diethyl sulphate, dipropyl sulphate, methyl ethyl sulphate, the higher symmetrical or unsymmetrical alkyl sulphates, mixtures of alkyl halides such as methyl and ethyl chlorides, sodium chloroacetate or chloroacetic acid may be used.  In carrying out the process, the starch grains may be gelatinized and methylating be effected with dimethyl sulphate, with or without subsequent heating to 80 DEG  C.; or a water suspension of ungelatinized starch grains may be methylated in the cold, with or without subsequent dilution and gelatinization; in the latter cases alkali is added gradually as methylation proceeds.  The products may be used as prepared or be purified as by precipitation with alcohols, particularly methanol. Fermentation of the products may be prevented by adding an inhibitor such as borax, boric acid, copper sulphate, camphor, &c., or by covering the surface of the methyl starch with toluene, benzol, &c. The Specification, as open to inspection under Sect. 91, comprises also the use, in the process, of etherifying agents generally, including chlorohydrine, ethylene chlorohydrine, glycerine chlorohydrine, ethylene oxide, and propylene oxide.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electric oscillation generators
IPC: H03D7/10
Filed: 1945-05-04
Abstract: 591,692. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., and WORSLEY, 1. R. May 4, 1945, No. 11347. [Class 40 (v)] An electric oscillation generator of. the heterodyne type, comprising two oscillating circuits; has the amplifying valve of one of these circuits in the same envelope as the modulating valve, and a condenser is connected between the anode of the modulating valve and a point in the oscillating circuit to neutralise the anode to anode capacity in the said envelope and prevent " pulling in " of the first oscillating circuit at low beat frequencies. In the Figure, a multi-electrode valve 1 comprises a triode amplifying section 2, 3, 4, associated with an oscillation circuit 13, 20, to generate a frequency f1. A similar circuit with valve 9 and oscillation circuit 24, 29, generates a frequency f2. The oscillations at frequencies f1 and f2 are fed to the two control grids 5 and 6 of the modulating section in valve 1, the difference frequency f1-f2 being extracted from the anode 8 by a filter (not shown) The anode to anode capacity in valve 1 (shown dotted at 39) provides a path for feeding back oscillations from anode 8 tu anode 4 and thence to the grid 3; which may cause the first oscillating circuit 13, 20 to oscillate at f2 by " pulling in " when #2 nearly equals #1. Condenser 40 is added between anode 8 and the upper end of coil 13 to neutralise this effect.

Filed: 1925-05-01
Abstract: 244,332. Rasetti, F. Jan. 24, 1925, [Convention date]. Fluid-friction vibrationdampers.-Relates to a fluid dash-pot of the type in which two pistons in a cylinder are connected by a piston rod which passes through a hole in a fixed diaphragm, fluid passing from one side of the diaphragm to the other through an aperture therein. The two pistons 7, Fig. 1, are mounted on a piston rod 5 connected to a bracket 15 on the axle of the vehicle while the cylinder 1 is mounted by a balljointed connection on a bracket 14 on the vehicle frame. The whole volume of liquid available for damping oscillation is contained between the two pistons. The piston rod 5 fits a hole in the diaphragm 4, the flow of liquid being regulated by grooves 5<11> of variable area. To avoid shocks when excessively rapid movement occurs, one of the pistons is slidable on the piston rod and is pressed into position against a shoulder by a spring 12. In a modification, the pistons are fixed on the rod and the cylinder is movable, under the control of a spring, in its spherical support. The piston rod and hole may be of square or other polygonal form with chamfered edges; or .the piston rod may be conical.

Abstract: 607,206. Variable - speed ratchet gear. S.A.T.A.M. SOC. ANON. POUR TOUS APPAREILLAGES MECANIQUES. May 5, 1945, No. 11482. Convention date, Sept. 26, 1941. [Class 80 (ii)] [Also in Group XIX] The rotary motion of a shaft 21 is transmitted to a member 29 with a ratio depending upon the angle to which a cam track 32 is tilted about an axis 24, this tilting being caused by certain variations iii the liquid dispensed by a dispensing apparatus (see Group XIX). A worm 22 is fixed to the shaft 21 and engages a worm 23 secured to a shaft 24 pivoted in the member 29. The shaft 24 also has fixed to it two cups 25 and has freely mounted on it two sleeves 26 each urged counterclockwise by a spring 33 to bring a roller 31 pivoted on each sleeve into contact with the cam track 32. Each sleeve 26 is connected to the adjacent cup through a ratchet device 38 which causes the sleeve to drive the cup 25 and hence the shaft 24 when the' sleeve turns clockwise, but not when it turns anticlockwise, the resulting relative motion of the worms 22, 23 modifying the transmission ratio between the shaft 21 and member 29.

Patent GB-331295-A (GB)
Title: Jelly preparation and a process of making the same
IPC: A23L29/231
Filed: 1929-04-15
Abstract: 331,295. Leo, A. April 15, 1929. Fruit jelly.-In the production of a jelly preparation comprising sugar and pectin, the pectin and sugar are so combined that the subsequent solution of the pectin in water or fruit juice precedes the solution of the sugar therein. An edible acid may be so combined with the pectin and sugar that the solution of the acid follows that of the sugar. In one form, the sugar particles are sprayed with a pectin solution and the coated particles dried. Preferably granulated sugar is used and a highly concentrated, e.g. 3-5 per cent pectin solution is sprayed or atomized thereinto, a heated air current being blown upwardly through the sugar causing a constant sugar suspension and at the same time drying the pectin coating on the sugar particles. In other forms, the sugar may be blown in a stream of heated air in a horizontal direction against an opposing spray of pectin solution, or the sugar particles may be blown into and allowed to fall by gravity in a dehydrating chamber, atomized pectin solution being directed against the falling sugar particles. The solution of the acid is retarded by coating the solid acid particles or crystals with an insoluble substance, e.g. solid paraffins having melting points from 100‹ F. to over 135‹ F., gum, wax or a, fatty substance such as stearic or palmitic acid or fatty substances containing these or similar fatty acids, which will liquefy at the temperatures reached in the jelly-making process, thus allowing the acid to dissolve after the pectin and most or all of the sugar have dissolved. In an example, 3 parts by weight of paraffin are dissolved in 100 parts of ether and 100 parts of powdered citric acid or other edible etherinsoluble acid are added and the ether evaporated leaving a thin paraffin coating on the acid particles. The dry pectin-coated sugar particles are mixed with the coated acid particles in the proportions necessary for making jelly. In use, the mixture is added at room temperature or a little above to water or unconcentrated fruit juices,À the pectin going readily into solution and the sugar following quickly. The mixture is then heated in the usual way and the insoluble coating on the acid particles melts exposing the particles which dissolve. The heating may be continued to approximately tlre boiling point, 218‹ F. or to a lower temperature depending on the amount of liquid used or, if fruit juices are added, the sugar, acid and pectin content of the juices. Boiling is unnecessary if the sugar content is sufficiently high to obviate concentration.

Title: Control means for buttonholing apparatus
Inventor: LEONARD WILLIAM THOMAS
IPC: D05B3/06
Filed: 1953-04-27
Abstract: 738,786. Buttonhole sewing-machines. TEXTILE TRIMMING & BOARDING MACHINE CO. April 27, 1953, No. 11614/53. Class 112. A buttonhole sewing-machine is provided with a member engaged by the tensioned sewing thread and biased so that on failure of the thread a tongue on the member engages parts of the buttonhole cutting mechanism to prevent the actuation of the cutter. The invention is shown in plan as applied to cutter mechanism as described in Specification 398,979, in which movement is transmitted from a link 78 actuated by the stop gear to a lever not shown when a vertical arm of a member 86 pivoted to the link lies under an abutment on the lever. The member 86 is normally held clear of the abutment against the force of a spring, by an arm 96 of the member resting on a lever 101 pivoted at 106 to a bracket 103; this lever is periodically tripped by a cam 118 driven in conjunction with the work-feed, to allow the arm 96 to fall, bringing the member 86 into operative position for engagement with the abutment to effect the cutter drive. An arm 151, pivoted at 154 to a depending bracket 149 designed for ready attachment to the machine frame by an existing screw, has a hook at its end to rest on the thread between the tension device and the take-up, a counter-balance weight 166 which relieves much of the pressure on the thread, and a depending arm 152 to which is fixed a tongue 159 adapted to engage beneath a lug 171 in the member 96. When the thread is properly tensioned the tongue 159 lies clear to the right of the lug 171, but if the thread fails the right-hand end of the arm 151 falls and the tongue moves to the position shown to prevent the fall of the arm 96 when released by the member 101; the member 86 is thus held clear of the abutment, and the drive to the cutter is ineffective.

Title: Improvements in or relating to clutches
IPC: F16D43/12
Filed: 1937-04-23
Abstract: 493,564. Friction clutches. BORG-WARNER CORPORATION. April 23, 1937 Nos. 11664 and 11665. Convention dates, Sept. 14, 1936 and Nov. 27, 1936. [Class 80 (ii)] A self-energizing friction clutch comprises a driven disc 7 located between the face of a driving flywheel 1 and a relatively-rotatable presser plate 20 which is urged towards engagement by springs 27, abutting against a cover-plate 10 secured to the flywheel, and which is adapted to be retracted through the agency of radial levers 50. The plate 20 is provided with lugs 35 across each pair of which is secured a plate 36 provided with a conical recess 38, while members 41, press-fitted into the cover, have opposed conical recesses 39, a ball 42 being arranged between each pair of co-operating recesses so that, as relative rotation between the plate 20 and the flywheel takes place during drive, the spring engagement pressure is augmented by the wedging action of the balls. The recesses 38 and 39 are preferably of different conicity. The levers 50, Fig. 1, the inner ends of which coact with the throw-out bearing 13 through adjustable studs 51, are pivotally mounted in forked brackets 32 secured to the cover, and their outer ends are held in contact, through balls 56 retained and capable of rolling in transverse grooves in the lever ends, with the plates 36 through the action of anti-rattle springs 58. The plate 20 is centred on a ring 21 which is slidably carried by the brackets 32, the forked ends of the latter engaging in apertures in the ring, and which is interposed between the plate 20 and the springs 27. The ring 21 carries friction facings 24 engaging the plate 20 so as to damp the free rotation of the latter. Each ball 42 is mounted in a retainer 45 having a stem 46 which is slidable and rockable in an aperture in the adjacent bracket 32, outward movement of the stem under the action of a spring 49, assisted by centrifugal force, being limited by a cross-pin. As the balls 42 are thus held in contact with the surfaces of the recesses, noise and jolts during torque reversals are prevented. In the modified form shown in Fig. 12, the ring 21 is held against rotation relative to the cover by means of flexible corrugated plates 65, one end of each of which is secured to the cover while the other end is secured to the ring. The forked ends of the brackets 32 still engage in the apertures of the ring 21, but with substantial circumferential clearance, so as to restrain the brackets against outward movement. Further, spring washers 70 are disposed between the cover and the body of the brackets, and the securing nuts 71 are rounded so as to permit a slight rocking movement of the brackets. The adjustable studs on the inner ends of the levers 50 are dispensed with, adjustment being effected by the nuts 71.

Title: Improvements in or relating to disc brakes for vehicles
IPC: F16D65/12
Filed: 1956-04-17
Abstract: 829,883. Disc brakes. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. April 17, 1956 [Sept. 26, 1955], No. 11699/56. Class 103 (1). In a spot-type disc brake, a brake disc 1 is secured to a vehicle wheel and a bracket 2, fixed to the vehicle, is provided with a forked extension 3-3 through which project rods 4-4 on which are slidably mounted brake segments 5, 6. The forked extension 3-3 also carries a spindle 7 at right angles to rods 4 on which is adapted to oscillate a U-shaped stirrup member 22-26 which houses a piston and cylinder mechanism 27 on limb 22 and which acts on brake segment 5; the other limb 26 of the stirrup member forming a jaw which bears on the other brake segment 6. When fluid under pressure is forced into the space between the piston and cylinder mechanism, the piston 25 is forced to the right to press braking segment 5 into frictional contact with disc 1 whilst the cylinder 24 is forced to the left, thus producing pivotal movement of the stirrup member about the spindle 7 such that the extremity 26 comes into contact with braking segment 6 to force the latter into frictional contact with the disc 1. Springs 28 act to withdraw the braking segments away from the disc by an amount which is limited by a ring 29 housed in groove in the limb 22 of the stirrup member and bearing with considerable friction on piston 25; the play of the ring 29 in the groove determining the clearance between the braking segments and the disc. Mechanical control of the brake is provided by means of a crank-arm 34, pivoting on pins 36 rigidly coupled to limb 22 of the stirrup, and provided with cams 37 which press the braking segment 5 against the disc 1 and by reaction, the stirrup member pivots about spindle 7 so that limb 26 is pressed against braking segment 6 so that the disc 1 is gripped in a similar manner to the action of hydraulic control. The cams may be manually adjusted when friction lining wear occurs. A further embodiment is described with reference to Fig. 7, wherein the brake disc 1 is fixed to the rim of the wheel 39 and the stirrup member 22-26 is located around the inner periphery of the brake disc. The brake disc is fixed to the rim of the wheel in this instance by means of a flexible flange 40 welded to the outer portion of the disc and bolted to the wheel 39.
