Patent GB-787464-A (GB)
Title: A penetration resistant fabric, and material produced therefrom
IPC: F41H5/04
Filed: 1954-08-09
Abstract: 787,464. Laminates. FRIEDER, L. P. Aug. 9, 1954 [Sept. 21, 1953], No. 23032/54. Class 140. A penetration resistant material comprises a layer of superimposed fabrics woven from yarn in which the individual threads are composed of filaments which are elongated to between 50 and 90 per cent of their ultimate elongation, each two fabrics being bonded together at intervals over their adjacent surfaces. The bonds may be formed by separate deposits of a plastic, such as a mixture of polyester resins and polyvinyl butyral resin, which may be applied as a pattern of spots, or, as shown in Fig. 7, of hollow triangles 25, those between successive layers being staggered. Alternatively the fabrics may be joined by quilting stitches 32, Fig. 8, which may pass diagonally or transversely through the material. The filaments composing to yarns from which the fabric is formed are preferably synthetic continuous filaments, such as nylon, but metal or glass filaments or staple fibre material may be used. The method of determining the amount of twist, required to give the filaments the necessary elongation, is described. The filaments in different fabrics in the same laminate may be elongated to different extents, e.g. some to 50 and some to 90 per cent of their ultimate elongations. The surface of the material may be metallized, e.g. by spraying with silver. Specification 777,586 is referred to.
Patent GB-389514-A (GB)
Title: Process for the manufacture of disinfectants
IPC: C07C37/00
Filed: 1931-08-15
Abstract: Phenols or such benzene derivatives as can be transformed thereto are converted into unsaturated phenols containing one alkenyl group of the formula -- CH2 -- CH = CH -- R or -- CH = CH -- CH2 -- R (R representing an alkyl group of 2 to 4 carbon atoms) which compounds have a high disinfectant power. Phenols may be employed as starting materials containing attached to the ring an alkyl residue of 5 to 7 carbon atoms possessing a substituent or substituents capable of being split off, and the alkyl residue can be converted by splitting off the said substituents into an alkenyl residue of the formula set forth. For example water may be split off from hydroxy alkyl residues or two halogen atoms or hydrogen halide from halogen alkyl residues. Alternatively unsaturated phenols of the first formula may be obtained when an alkenyl halide of the formula Hal--CH2--CH = CH--R (R representing an alkyl group of 2 to 4 carbon atoms) is caused to react on a phenate in a non-dissociating organic solvent.  The product so obtained may be rearranged to form a 1,2 alkenyl phenol. Further a benzene derivative containing the desired alkenyl group and a substituent convertible into a hydroxyl group may have that substituent so converted.  In examples, (1) sodium, phenol and benzene are heated until the phenate is formed and then treated with n-2,3-pentenebromide to yield o-n-2,3-pentenephenol which may be converted into the corresponding 1,2 compound by treatment with methyl alcoholic caustic potash.  (2) Salicylic aldehyde is treated with n-butyl magnesium bromide (prepared from butyl bromide and magnesium to give o-n-1,2-pentenephenol.  (3) Water is split off from 4-methoxy-1-hydroxy pentenebenzene (prepared from anisic aldehyde and butylmagnesium bromide to give 4-methoxy-1-pentenebenzene. This compound is heated with ethylmagnesiumbromide to obtain p-hydroxy-1,2-pentenephenol.

Title: Reversing device for gear driven turbine aggregates
IPC: F01D15/02
Filed: 1921-08-31
Abstract: 177,759. Ljungstr÷m, r. April 1, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Clutches, friction.-The drive of a turbine is reversed without reversing the turbine by turning the turbine end for end in relation to the driven member. Fig. 1<a> shows a turbine 1 rotatably mounted on the neck 18 of a condenser 17 so that either end of the turbine shaft 3 may be clutched through a coupling 7, 8 to a shaft 9 driving a reduction gearing. The shaft 9 passes through a hollow gear shaft 11 and transmits the drive with some resiliency through an axially movable element such as a square coupling. The clutch is operated by a servo-motor. A brake device on one of the gearing shafts preferably controls the servo-motor so that the clutch cannot be operated before the braking is performed ; preferably the braking cannot begin before the steam supply is cut off. A brake 3<a> on the turbine shaft prevents rotation during the turning of the turbine which may be carried out by rack-and-pinion gearing driven by a servomotor 37. Conical friction couplings or dog clutch couplings may be used. In Fig. VIII is shown a friction clutch comprising a number of segmental annular parts 107 supported by parts 109, 110 on the hollow driving shaft 105 and held in place by an elastic ring 108. A resilient flange of a casing 112 on the driven shaft 106 engages the annular parts 107, on the shaft 106 being moved forward. The annular parts 107 are sprung past the central position and bear on the part 109 with sufficient friction to drive the shaft 106. A rigid flange may limit the movement of the resilient flange. When the coupling is in engagement, as shown in lower half of Fig. VIII no further axial thrust is required.

Filed: 1938-08-06
Abstract: 518,019. Trueing grinding-wheels. ATKINS, H. F. Aug. 6, 1938, No. 23262. [Classes 60 and 124] A grinding-wheel 1 having a spiral rib (not shown) is formed or trued by means of a spirally ribbed steel or other roller 11 rotating in synchronism with the grinding wheel. The wheel and trueing-roller are both mounted in bearings on a base plate 5 and are driven from a pulley 10 through worm gears 7, 22 respectively. The roller may be moved towards the grinding wheel by a screw 18 or the grinding wheel may be adjustable as well as or instead of the trueing roller. The speeds may be varied according to the number of starts of the ribs on the grinding wheel and trueing roller. Thus a roller 11 having double start ribs, will dress a single start rib on the grinding wheel if it revolves at half the regular speed of the grinding wheel and a four start rib if it revolves at twice the angular speed of the grinding wheel.

Title: Improvements in plate heat exchange apparatus for fluids
IPC: F28D7/04
Filed: 1933-08-23
Abstract: 424,580. Plate heat - exchangers. STONE & CO., Ltd., J., Deptford, London, and PIKE, F. J., Fairway, Mapledale Avenue, Addiscombe, Surrey. Aug. 23, 1933, Nos. 23490 /33 and 4051/ 34. [Class 64 (iii)] In apparatus comprising ribbed or corrugated plates interleaved with flat plates and adapted to be clamped together as by screw action, relatively thick drum-like plates b are employed and are removably mounted within border frames or carriers d between which the thin plates a are clamped. By this arrangement the thin plates and the drum-like plates may be removed from the assembly for cleaning while the heavier border frames may remain in position on the horizontal bars f or like supports. The thick plates may be formed by uniting ribbed plates to inner and outer spacing rings q<1>, q, and may be filled with insulating material such as plywood or cork. The border frames are formed with openings r, s, t, u, one of which on each face leads to a channel r<2>, or u<2> communicating with the outermost part of the spiral path formed by the ribs on the plates, and the plates and frames may have co-operating lugs and notches v, v<1> to ensure correct registration of the channels. Packing cords l are employed between the border frames and the thin plates. The passages may be so arranged that one fluid circulates on both faces of one thick plate and another fluid on both faces of the adjacent thick plate, in which case the joint between the outer ring q and the border frame need not be fluid-tight. In a modification, solid ribbed plates may be used and rubber packing cords may be located in grooves on the crests of the ribs to ensure tight joints with the thin plates. Hollow thick ribbed plates alternate with the solid plates, and the outer rings of the hollow plates engage packing cords on the inside rims of the border frames to ensure a tight joint. Where brine is circulated over the solid plates and milk over the hollow plates, only the hollow plates need be removable, and the thin separating plates may be united by screwing &c. to the frames of the solid plates. The thick plates may be flat, in which case double thin plates formed with outwardly directed ribs may be placed back to back between the frames ; or single thin plates with ribs on each face may be used. An assemblage may include several sections connected through section plates, one section being used for heating milk, another for heat exchange between hot and cold milk, a third for cooling milk by water, and a fourth, with non-removable plates, for cooling milk by brine. The brine is retained in the plates during the cleaning operation.

Filed: 1947-08-28
Abstract: 635,255. Hydraulic machines. ELECTRO-HYDRAULICS, Ltd., PERDUE, J., and HACKNEY, S. Aug. 28, 1947, No. 23890. [Class 69 (ii)] [Also in Group XXXIII] An automatic locking device, such as for a hydraulic jack, comprises a lock bolt 5 carrying a switch 8, arranged concentrically with a sleeve 6 within the cylinder 1 and a striker 7 normally biassed away from, as by a spring 9, and axially movable relatively to the switch, the arrangement being such that during the latter part of the movement, wherein the movable parts of the device are approaching the locking position, the bolt and switch are caused to move relatively to the striker to effect the locking and close an electric circuit to indicate that the movable parts are locked. In one embodiment, pressure fluid admitted at connection 14 moves the piston 2 towards the locking position, and the piston carries with it the bolt 5, contacted by radially contracted tongues 4, the striker 7, the position of which relatively to the switch remains unaltered, and the sleeve 6. The tongues, after passing through the guide 15, regain their undeformed state, the bolt is urged by spring 11 back to its initial position to effect the locking, and the striker, held immovable by the sleeve, is contacted by the switch. To unlock the jack, admission of pressure fluid at connection 16 causes movement of the bolt away from the piston, thus allowing the tongues to pass back through guide 15. In a modification, the switch and striker may be positioned within the cylinder, the former, biassed away from the switch, passing through the bolt to be directly contacted by the piston. Specifications 527,225 and 564,590 are referred to,
