Title: Method for packaging, mixing and dispensing a plurality of substances
IPC: B65D83/14
Filed: 1963-09-25
Abstract: 1,059,265. Dispensing liquids by gaseous pressure. LABORATOIRES CHIBRIT. Sept. 25, 1963 [Sept. 27, 1962], No. 37653/63. Heading F1R. Substances which can only be mixed immediately before use are stored separately in a storage container B and a dispensing container A, which are interconnected for mixing in container A, a jet or spray head D, Fig. 4 (not shown) being used on the latter for dispensing. Liquid L is stored under a gas pressure higher than the dispensing pressure in container B which has a female "aerosol" type valve 2. The other substance, which may be a solid in liquid suspension, is stored in under a gas pressure lower than the dispensing pressure in container A having a male "aerosol" type valve. Containers B and A are interconnected as shown pressure being applied to container B to allow liquid to be expelled by the gas in container B. When all liquid L is mixed in container A the gas pressures are equalized at the initial dispensing pressure. The containers may be of glass and sheathed in a plastic. One of the container closures may be a needle, formed with an axial duct controlled by a valve, which is adopted to penetrate a diaphragm closure on the other member. Dispensing containers which have been discharged may be recharged by further sets of storage chambers at least one of which is charged with gas at a pressure higher than the initial dispensing pressure. The substances to be mixed may be in one container: a quaternary ammonium compound, an antibiotic, a lyophilized vaccine prepared from at least two influenza viruses comprising the viruses A1, A2, B and para influenzae under nitrogen pressure and in the other container a physiological salt solution or a solution of quaternary ammonium compound.
Patent GB-1449417-A (GB)
Title: Apparatus for compacting a nonwoven fabric to improve hand and drape
IPC: D04H17/00
Filed: 1974-08-30
Abstract: A moistened fibre fleece (11), which contains a thermoplastic binder and which is already preconsolidated, is guided over a rotating drum (12), the outer surface of which is covered with a layer (31) of low-friction material, for example Teflon. This outer surface is heated to a temperature which is higher than the softening temperature of the binder in the fibre fleece. A further adhesive binding of the fibres in the fibre-fleece region guided so as to rest on this outer surface thereby takes place. The drum outer surface is part of a device for compressive shrinkage. This includes an elastic band (16) which partially loops round the drum and against which the running fleece bears. As a result of the contraction of this band, the fleece is also moved by adhesion and at the same time shrunk by longitudinal compression. The fleece thereby slips along the low-friction layer (31) covering the drum outer surface. Simultaneously with the further adhesive binding of the fibres of the fleece, an improved shrinkage takes place, since the drum outer surface opposes only slight resistance to the longitudinal compression of the fleece. <IMAGE>

Title: Improvements in or relating to indicating arrangements for counters
IPC: H04M15/30
Filed: 1930-12-17
Abstract: 357,881. Counting-apparatus. RICHTER, M. B., (trading as TELEFON FABRIK AUTOMATIC), 7, Amaliegade, Copenhagen. Dec. 17, 1930, No. 38108. Convention date, Nov. 4. [Class 106 (i).] A counter, particularly for telephone calls, is provided with means for signalling the attainment of a desired total comprising a member adapted to be displaced to fall into exposed position. In the form shown in Figs. 1 and 2, a bar 23 is rotatably mounted in the counter framework and has an arm 25 extending into the path of the teeth of a particular transfer pinion 15. When this pinion is moved, owing to a predetermined total having been reached, the bar is rocked clockwise and another arm 26 abuts through a hole in the casing against a lug 28 of a signal arm 21 pivoted on the casing at 22. This arm is therefore pushed beyond the vertical and falls into an exposed position. A further arm 24 on the bar acts as a stop by engaging the rod 13. In another construction, Fig. 6, the signal is in the form of a hinged plate 21<1> normally covering the subscriber's number 30 and displaced by the rocking of the bar which, however, is effected by an adjustable pin on one of the numeral wheels instead of by a transfer pinion.

[Class 122 (iv).] In apparatus wherein the fuel supply is cut off by a valve upon failure of the pressure of the lubricant supply, a dashpot is provided to delay the operation and manual or foot operated means are provided for opening the valve. A plunger 12 is subjected to the lubrisating-oil pressure passing through passages 13, 14 and is provided with a recessed part 25 which permits the flow of fuel through the passages 15, 16 in the position shown. The plunger has a head 19 which slides in a cylinder closed at the bottom by a plug 22 and open at the top to the fuel passage 15 through a restricted passage 21, or through a non- return valve 29 with restricted passages 30 in its body or in the valve seat. The head 19 is recessed to receive a spring under compression. When starting, a lever 28 engages a rod 17 secured to the plunger and depresses it. The plunger rises slowly owing to the dashpot until the pressure of the lubricant arrests it. Should the pressure fail, or build up too slowly, the fuel supply will be cut off.

Title: Tyre building drum
IPC: B29B13/00
Filed: 1972-08-22
Abstract: 1380113 Tyre building drums GOODYEAR TIRE & RUBBER CO 22 Aug 1972 [24 Sept 1971] 39016/72 Heading B7C A collapsible tyre building drum comprises a first set of part-cylindrical segments 42 (e.g. three, four or five segments), connected to a tubular shaft 12, e.g. by pivoted links 32, and a second set of removable part-cylindrical segments 60, the segments 60 being arranged alternately with and connected to the segments 42 to form the cylindrical drum surface. Removal of the segments 60 of the second set permits the segments 42 of the first set to be collapsed towards the shaft 12 by application of an axially directed force to a tyre on the drum to facilitate removal of the tyre. As illustrated, each segment 60 has on one axially extending edge a projection 64 which, upon assembly of the drum is received in a groove 66 of one adjacent segment 42. The other axially extending edge of segment 60 is secured to the other adjacent segment 42 by a pin 82. Annular supports 90 also each comprise a plurality of segments 102, 102a interengaged by pin and socket connections 108 and secured in position by a key segment 100 locked in position by spring-loaded latch pins 110. In operation, after building of the tyre, the annular supports 90 are manually removed, and then the segments 60 are removed. The axially directed force is now applied to the tyre. The tyre may be supported by a sling 150 suspended from an overhead crane. A lock nut 142 may be applied to the drum to prevent movement of the segments relative to the shaft 12 during building of the tyre.

Title: Method of Fining Glass
IPC: C03B5/225
Filed: 1967-08-24
Abstract: 1,159,647. Firing glass melts. CORNING GLASS WORKS. 24 Aug., 1967 [29 Aug., 1966], No. 39023/67. Heading C1M. A method of firing glass melts comprises fusing a glass composition in an atmosphere in which helium is substantially absent, causing gaseous helium to pass into the molten glass so that the helium diffuses through the glass and into the seeds whereby they become expanded and rise through the molten glass to be eliminated at the surface. The helium may be bubbled through the melt or it may diffuse into the melt from a surrounding helium atmosphere. A standard chemical firing agent may also be used, sodium chloride being used in the example given.

Abstract: 1519804 Loading containers on to vehicles SOC NOUVELLE DES BENNES SAPHEM 24 Sept 1975 [2 Oct 1974] 39173/75 Heading B8Q An L-shaped loading arm on either side of a truck has a hook 9 on its vertical branch 8 to engage a container and the horizontal branch 7 has a slipper 5 slideable in a slideway 28 of an arm 4 of a sub-frame 25 pivotally mounted on a shaft 3. A pivot shaft 12 also on the branch 7 slides in a groove 29 until an accommodation 30 in a stop 6 is reached. A single actuating ram 31 thus can slide the arm to the dash line position in which the shaft 12 is at 30 and the slipper 5 is opposite an opening in the top of the arm 4 so that continued extension of the ram 31 causes the branch 8 to follow the path C1 in the usual loading/unloading action. The ram 31 may act through an amplifying linkage as shown or may be pivoted directly on the branch 7. If the movement of the slipper 5 is prevented and an attached container is locked to the arms 4 the ram will cause it to be tipped about the shaft 3.

Title: Improvements relating to screw-tightened compression sealing glands for electrical cable
Inventor: MORDUE HAROLD
IPC: H02G15/013
Filed: 1958-12-04
Abstract: 928,336. Mechanical couplings for cables. A. REYROLLE & CO. Ltd. Dec. 3, 1959 [Dec. 4, 1958], No. 39199/58. Class 38 (1). A compression-sealed gland for an electric cable 14 comprises a base 10 screw-threaded at 15 for engagement by a locking sleeve 24 having a portion of reduced diameter which is fitted over the external polychloroprene cable sheath 28 surrounding the armour 20. The base 10 also includes a tapered tubular anvil 16 provided with light radial saw cuts 37 and a circumferential groove 40 which aids the constriction of the fingers defined between the saw cuts. An abutment shoulder 33 on the locking sleeve 24 engages against a brass or cadmiumplated steel clamping ring 34 of which the clamping surface 35 engages the outer layer of the double-layer wire armour 20; a separator pad 32 of brass or cadmium-plated steel may be inserted between the layers of the armour. A synthetic rubber sealing sleeve 41 fits closely around the inner sheath 19 of the cable, but when the sheath is of a conducting material such as lead the sleeve is also made of conducting material so that the sheath is earthed to the base 10. When the locking sleeve 24 is tightened up by rotation on the threaded portion 15 of the base, the clamping ring 34 forces the fingers of the anvil to yield inwardly and compresses the sleeve 41 on to the cable sheath 19. A fluid-tight seal is also formed against the outer cable sheath 28 by a resilient washer 30 acted on by a screwed cap 29. In a modification, Fig. 4, the splayed end 67 of the cable armour is folded over a clamping ring 58 having a double taper and is secured by wire binding 68 to a groove 69 formed in the ring 58. Additional saw cuts 66 are made in the outer flange 61 of the base 60. On screwing the locking sleeve 51 into position, the splayed armour is clamped at the inside and outside of the clamping ring 58 and the flange 61 is expanded and locked by friction with the sleeve 51 which is thus prevented from becoming unintentionally loosened.

Abstract: 854,188. Dynamometers. WALKER & CO. (ENGINEERS) Ltd., W. G. March 3, 1959 [Dec. 19, 1957], No. 39452/57. Class 106 (2). A dynamometer for testing the power and/or torque developed at the driven road-wheels of motor vehicles comprises a roller 11 journalled in a frame 16, means which may comprise a second roller 10, to retain the wheels in frictional contact with the roller 11 to which a rotary fan 24 is connected and means 31 for measuring the rotation of the fan. The roller 11 is connected by a flexible coupling 17 to a pulley 18 coupled by a pulley belt 19 to a pulley 20 which is mounted on a shaft 21. The fan 24, enclosed by a shield 25, is connected to the shaft 21 and is embraced by a cylindrical cowl 26 adjustable axially by a lead-screw 27 engaging a threaded hole in a bridge 43 and which is connected to a hand-wheel 29. The rotational speed of the fan 24 is measured by an instrument 31 which receives a voltage proportional to the rotation from a tachometer generator 30 coupled to the shaft 21. The torque developed and power dissipated by the fan at any rotational speed depends upon the axial extent of the fan uncovered by the cowl 26. Calibration curves for the fan brake may be provided for various overlaps of the cowl 26 at various speeds. From these curves the torque developed and power dissipated under any conditions may be deduced from the overlap of the cowl 26 and the speed of the shaft 21. A control panel 32 on which the instrument 31 is mounted, may be provided with an electrically driven pump 33 which circulates cooling water through pipes 34 to the radiator of the vehicle. In a modification a mechanical tachometer is coupled to the shaft 21 in place of the generator 30 and the instrument 31. A locking clutch may be provided to lock either of the rollers against rotation to enable the vehicle wheels to climb over the roller 10 which is adjustable to and from the roller 11 to accommodate wheels of different sizes. According to the Provisional Specification the fan may be equipped with torque and power indicating means, as described in Specification 741,146.
