Title: Pressurised dispenser and cap therefor
IPC: B65D83/14
Filed: 1980-02-06
Abstract: A pressurised dispenser of the aerosol can type has a cap fitted over the press button which requires the use of a screw driver or other implement to remove it from the container, thereby to deter children, for example, from using the dispenser. The cap has an inner skirt (3) having a formation (5) which snaps under a fixed shoulder (15) to secure the cap in position, and an outer skirt (4) which seats on the top of the container. There is a slot (9) in the outer skirt through which the implement (17) can be inserted to engage with a bearing surface inside the cap for prising formation (5) out of engagement with shoulder (15) so as to release the cap. As shown, the bearing surface is formed jointly by bottom edges of vertical ribs (6) on the inner skirt. In an alternative form Fig. 3 (not shown), the bearing surface is provided by the top of the container, the implement being swung upwards to apply upward force on the outer skirt at the top of the slot for prising the cap off the container. <IMAGE>

Title: Mobile Working Platform
IPC: E06C7/42
Filed: 1980-02-15
Abstract: The invention relates to a mobile working platform particularly for use in maintenance work on marine vessels. The platform (Figure 1) has a hollow base (10) of plastics or metal which acts as a ballast tank for liquid or granular ballast. Mounted on the base by means of brackets 9 and welded struts 8 is an extending vertical lightweight ladder 11 with an adjustable arm 12 to give it rigidity when placed next to a vertical surface 13. A movable platform or cradle 14 is mounted on the ladder 11 between it and the vertical surface fitted with a safety rail 15, a locking device 16 to secure the platform on any of the rungs of the ladder and a flexible strap 17 which is placed over the shoulders of the operator, by which means the operator raises the platform to the desired height. The ladder 11 and cradle 14 may in another embodiment, be cantilevered from the mobile base or ballast tank by means of a steel or aluminium outrigger. A pair of smaller mobile bases or ballast tanks may be used in confined spaces to support the ladder and cradle. <IMAGE>

Patent GB-2072880-A (GB)
Title: Movement Transducer for Automatic Machines
IPC: B25J9/00
Filed: 1978-07-03
Abstract: A transducer arrangement is provided for monitoring the movement of the working head (540) of an automatic machine whereby to generate a signal indicative of said movement for use as a demand or feedback signal during automatic operation of the machine. By means of a kinematic coupling (548, 549) extending between the working head (540) and fixed structure (504) of the machine, a movable member of the transducer arrangement (551, 550) is displaced with a velocity dependent on that of the head (540) relative to the fixed structure (504). The movement of the transducer movable member is translated into a corresponding frequency deviation in a reference carrier signal by utilising the Doppler shift effect. Preferably, the kinematic coupling takes the form of a trace wire (548, 549) connected between the working head (540) and the transducer movable member. <IMAGE>

Title: Ergot alkaloids
IPC: C12P17/18
Filed: 1981-02-09
Abstract: The invention relates to a new method for controlling the level and distribution of alkaloids produced by Claviceps purpurea variant strains capable of producing primarily ergo-cornine,  alpha -ergocryptine and  beta -ergocryptine under saprophytic conditions. According to the invention a compound of the bio-synthetic path of isoleucine or a compound which promotes the formation of isoleucine by biochemical control is added to the fermentation broth.

Title: A clamped telescopic shock strut for aircraft
Inventor: YNTEMA ROBERT THEODORE
IPC: B64C25/62
Filed: 1961-08-31
Abstract: 952,119. Hydro-pneumatic shock-absorbers. BOEING CO. Aug. 31, 1961, No. 31355/61. Heading F2S. [Also in Division B7] In an oleo-pneumatic shock absorber strut 16, particularly for damping ground resonance of V.T.O.L.-type aircraft, and comprising a hollow telescopic piston and cylinder unit 20, 21 in which the piston 20 has a metering orifice in parallel with two one-way pressure responsive valves and with a floating piston 35 loaded on its underside with a predetermined gas pressure introduced through a valve 8 the force, due to the weight of the piston 20 and its wheel load plus the pneumatic preload when the aircraft is just airborne, is balanced by a compression spring assembly 26. The latter is interposed between a bearing 25, secured by a nut 27, provided with an inner seal and a scraper ring, and the lower end of a load transfer sleeve 23, the upper end of which co-operates with a bearing 24 attached to the piston assembly 20. The spring assembly 26, preferably consisting as shown of a number of dished washers but which may incorporate liquid or air springs, is not bottomed by the total force acting upon it during a full extension stroke of the strut and preferably has a low substantially-linear spring rate. In a modified spring assembly, Fig. 4, the spring 26A is adjustable by rotation of a threaded cap 26D. During a compression stroke fluid under pressure in an upper chamber 29 initially passes through an orifice 31 and an opening 42 in a poppet valve assembly 32, the latter being opened for large, rapid, motions so that liquid passes through a large orifice 33 and openings 40, 41. If large, rapid changes of external load occur, e.g. in a jump take-off, a check valve 34 is forced open. The piston 20 is rotatably restrained with respect to the cylinder 21 by a torque link scissors 22.

Title: Improvements in or relating to drive shaft couplings
Inventor: SAWBRIDGE BARRIE ERNEST
IPC: F16D1/06
Filed: 1982-03-31
Abstract: The present invention provides an arrangement for coupling a first drive shaft (42) to a coaxial second drive shaft (38), the drive shafts being drivingly connected together by a splined coupling (40). A first ring (56) which has an internal diameter less than the external diameter of the splines (54) on the first drive shaft (42), and the first ring (56) is positioned coaxially within and secured to a second ring (58). The second ring (58) abuts and is secured to the second drive shaft (38). In operation the first ring (56) abuts the splines (54) on the first drive shaft (42) and prevents the splines (52) on the second drive shaft (38) sliding out of engagement with the splines (54) on the first drive shaft (42). A lubricant is supplied to the splined coupling (40), and the first ring (56) forms a lubricant weir in order to provide full depth lubrication of the splines (52 and 54), and a sealing ring (62) is positioned axially between the second ring (58) and the second drive shaft (38) to prevent leakage of the lubricant between the second drive shaft (38) and the second ring (58). <IMAGE>

Title: Device for the individual actuation of extra steam in steam flat-irons
IPC: D06F75/18
Filed: 1982-04-02
Abstract: A device for supplying extra steam in a steam flat-iron with a water container 7 and an electrically heated sole 1 having an evaporation chamber 2, comprises a dropper valve for freeing and interrupting the water supply by rotation of a water inlet 13, in a valve body 6, and a regulator needle 16 situated in the dropper nozzle 15, by the lifting of which out of the nozzle 15 extra steam is generated. It is the aim of the invention to realise, with the simplest means and few components, a dropper valve with extra steam device which works according to the above-stated principle, is simple to fit, favourable of cost and also of low susceptibility to faults, and can easily be inspected, cleaned or replaced by the user. To achieve this, the needle 16 is hooked, for the purpose of axial movement, in a leaf spring 19 which also takes over the function of retention and return of a lever 18 which is snapped into a handle 17 by means of lateral pins at its pivot point. The handle 17 is moulded on to a hollow cylinder which also contains the dropper nozzle 15 at its lower end, so that with few parts and low assembly expense the valve needle with extra steam device can be produced as one constructional group. <IMAGE>
