Patent GB-2472237-A (GB)
Title: Ultrasonic Non-Penetration Level Measurement
Inventor: ZHANG JINGDONG
IPC: G01F23/296
Filed: 2009-07-30
Abstract: An ultrasound non-penetration level sensing method and apparatus as applied to the outer wall of a tank. A level sensing transducer 10 is mounted to the exterior of a tank, the tank wall having an outer surface 18, an inner surface 19 and a thickness `t'. The transducer 10 has a transducer body 20, one end surface 21 being the surface from which ultrasonic energy is transmitted and by which reflected energy is received. A sealed chamber 23 is defined at least between surface 21 and adjacent surface part 24 of the tank outer wall 18. The chamber 23 is filled with an acoustic coupling fluid. A further aspect of the invention resides in the manner in which operating frequencies are selected to maximise the difference between wet and dry reflected signals.

Title: EMI shielding collar with dimpled fingers which may have a lap-joint
Inventor: MCCOLLOCH LAURENCE RAY
IPC: H05K9/00
Filed: 2009-09-03
Abstract: An electromagnetic interference collar 50 is mounted via a band portion 60 onto a housing 21 of a pluggable optical transceiver module 20 that can fit into a cage (10 fig 1). Preferably the band has ends forming a lap-joint 80 which may be welded and thus caused to tighten as it cools around the housing 21. The collar band carries spring fingers 70 whose outer surface contact the inside of the cage. The fingers have dimples / indentations 100 that provides two contact points 110 (see also fig 6) at each end. These additional contacts results in a reduction in the size of the maximum EMI aperture dimension of the collar, which improves the ability of the collar to attenuate EMI signals, even EMI signals having high frequencies. The dimple length end-to-end is preferably a quarter, more preferably an eighth and most preferably a tenth of the wavelength of an EMI signal to be attenuated.

Title: Garment carrier
Inventor: BRUNDAN ANDREW
IPC: B65D85/18
Filed: 2009-09-30
Abstract: A garment carrier is disclosed, comprising a former 3 having a body 6 with the opposed edges 8, 9 radiussed so that a garment 2 wrapped round the former 3 is not creased by being wrapped round the radiussed edges 8, 9. The former 3 is preferably generally rectangular in shape having a collar support 7 extending from one end, and the radiussed edges 8, 9 extending along its sides and optionally its other end 10. A shirt 2 is mounted to the former 3 by spreading out the buttoned shirt 2 face down, placing the former on the back of the shirt 2 with the collar support 7 inside the back of the collar, and folding the sleeves round the radiussed edges 8, 9. Each sleeve is doubled back over the former 3, and the tail of the shirt 2 is finally folded over the end 10 of the former 3 remote from the collar support 7 and retained to the back of the former by a retaining device 11, (50). The shirt 2 and former 3 are then placed in a protective container 4 for transport, located within the container 4 by cushioned blocks 20. The protective container 4 may be weatherproof, and may be adapted to be secured to a bicycle or placed in a backpack 5.

Title: Fluid control valve
Inventor: CROOK GEORGE LEWIS
IPC: F16K1/30
Filed: 1968-03-04
Abstract: 1,254,532. Valves. BRITISH OXYGEN CO. Ltd. 3 March, 1969 [4 March, 1968], No. 10297/68. Heading F2V. A fluid control valve comprises a valve body having a passage 6 in which a control shaft 9 is movably mounted, a shoulder 5 located in the passage defining a forward limit position of the shaft 9, a valve seat 3, a plunger arrangement comprising a plunger body 10 coupled to the shaft 9, a piston 15 slidably mounted in the plunger body 10, and biasing means 13 biasing a forward portion 21 of the piston 15 into sealing engagement with the valve seat 3 at a preselected force. The forward portion of the piston 21 is made of a soft material e.g. nylon, which seals against an inlet seat 3 of a container for storing gas under pressure. An elastomeric spring 13 urges a ball 14 into contact with a grub-screw that affords an adjustable means of selecting the pressure on one side of the piston 15. In use, the cylinder is filled by passing gas through the passage 4 to passage 2, the shaft 10 being retracted whereby the ring 16 engages the piston 15 to lift the valve member from the seat 3. When the shaft is turned to close the valve, the shoulder 5 prevents the shaft 10 from travelling too far into the bore. Pressure in the cylinder above the predetermined value causes the valve member to lift off its seat against the force of the elastomeric spring 13.

IPC: G03C1/805
Filed: 1927-04-21
Abstract: 269,912. Klaver, L. April 21. 1926, [Convention date]. Films and papers, stripping; colour photography. -To facilitate stripping, there is interposed be. tween the sensitive layer, which is preferably unhardened, and its liquid-pervious support a layer of casein which is readily soluble without heating in dilute ammonia solution without injury to the sensitive layer. The support may consist of black or dark red paper. Three-colour prints may be produced by applying a piece of sensitive material to glass or celluloid coated with wax, printing for example from the blue-record negative through the glass or celluloid, stripping the original paper support after wetting its back with a half per cent solution of ammonia, and developing, colouring, and hardening the image layer. After registering the print so produced in the printing-frame with the red-record negative, the print is removed and a fresh piece of sensitive transfer material is applied to it without previous waxing, whereafter the print is restored to its registered position in the frame, and the red record is printed through the glass or celluloid, developed, coloured, and hardened as before. The yellow image is superimposed in the same manner as the red. The completed picture is finally transferred from the glass or celluloid to paper. Relief images may be produced by development with a tanning developer followed by etching away of the soft gelatin. The sensitive layer may, if desired, be ready-coloured.
