Title: A guide roller for a woven or knitted fabric web
Inventor: CRAMER HANS
IPC: B65H27/00
Filed: 1987-07-08
Abstract: In order to be able to apply a strip-out effect to either a woven or a knitted fabric web 10, in the direction of its width, differently depending on requirements, cylinder segments 8, 9 are associated with a guide roller 1 at a radial spacing from the roller jacket 2. These segments 8, 9 are arranged in a diametrically opposed manner and are provided on their convex outside with helically diverging beads 11 or respectively 12. Depending on whether the fabric web 10 is conducted directly over the guide roller 1 or over the one or other cylinder segment 8, 9, the fabric web 10 is subjected to no strip-out effect, to a comparatively slight strip-out effect or else to a comparatively great strip-out effect. <IMAGE>

Title: Respiratory protective apparatus
Inventor: SIMPSON KEITH
IPC: A62B17/04
Filed: 1987-10-13
Abstract: A flexible hood (1) of respiratory protective apparatus envelopes the head of a wearer and includes both a mask (3) engaging the face of the wearer of the hood (1) and a neck seal (5) engaging the wearer's neck.

Title: Extendable line with detent device
Inventor: KANG DON MIN
IPC: G01B3/10
Filed: 1987-12-11
Abstract: A self-retracting line 4, such as a tape measure, is coiled on a reel 1 rotatably mounted in a housing 2. The reel 1 contains a spiral spring 8 to retract the line 4. The line 4 is locked in an extended position by a plunger 9 which can be pushed into engagement with projections 6 formed on the reel 1, thus locking the line 4 without direct engagement with the line 4. This avoids damaging the line 4, such as erasing markings from a tape measure. The plunger 9 is urged out of engagement with the winding case 1 by a spring 12, and is locked into engagement by a locking member 14 cooperating with a recess 13 on the plunger 9. <IMAGE>

Title: Magnetic treatment of fluids
Inventor: WOODHOUSE DEREK ALFRED
IPC: C02F1/52
Filed: 1992-03-06
Abstract: A device for treating hard water to counter the deposition of scale comprises a non-magnetic conduit 5, means 6A, 6B external to and in contact with the conduit for generating a magnetic field which passes through the conduit and a magnetisable element comprising coiled and/or twisted steel wire 9 located in the conduit in the path of water flow, whereby in use the wire becomes magnetised and the water flows through and in contact with the magnetised wire in its passage through the device. The treatment induces coagulation of scale forming particles in the water and reduces deposition of scale on pipes or other vessels into or through which the water flows. The magnetic field may be generated by permanent magnets as shown or by electromagnets and coagulation may be assisted by adding an electrolytic device which releases salt particles and ions into the water. <IMAGE>

Title: Armour
Inventor: SACKS MICHAEL
IPC: F41H5/04
Filed: 1992-08-03
Abstract: The armour comprises a flexible sheet (2) having a threat side facing a direction of threat and a protected side, and a plurality of armour plates (4) attached to the sides of the sheet (2), the plates (4) being grouped such that a first group attached to the protected side is in overlapping registration with a second group attached to the threat side. the registration being such that exposed regions of sheet (2) on the threat side register with the first group of plates (4) so preventing penetration of the armour through the exposed regions.

Patent GB-927560-A (GB)
IPC: H04R1/16
Abstract: 927,560. Stereophonic pick-ups. RADIO CORPORATION OF AMERICA. Oct. 15, 1959 [Oct. 31, 1958], No. 35004/59. Class 40 (4). A gramophone pick-up, Figs. 1, 2, 3, comprises two elongated piezo-electric transducers 22, 24 of oblong cross-section supported at one end in a block 26 of compliant damping material with their major faces parallel, the arrangement being such that sufficient slippage of the transducers in the block in the direction of their greater cross-sectional dimension is permitted to provide a reduced response to low-frequency vertical modulation components (e.g. turntable rumble). A yoke 30 connects the other ends of the transducers 22, 24 and is coupled to a stylus arm 38 carrying a stereophonic stylus 40. The yoke 30 comprises a wire having divergent legs 30a, 30b, Fig. 4c, extending from its central portion, the legs being adapted to flex individually to change the angle of incidence between them. An additional yoke 46 has a web 49 connecting its divergent wire legs and is coupled to a stylus arm 48 carrying a monaural stylus 50. The web 49 restrains these legs from flexing to change the angle between them. Decoupling portions 56, 58, permit the transducing elements to move substantially independently when stereophonic records are played. In addition to the damping block 26, auxiliary dampers of " Viscoloid " or other damping material may be provided. The transducers are Rochelle salt crystals or are of barium strontium titanate. A two-part casing 12, 14 is provided and the whole forms a cartridge of the turnover type.
