Patent GB-2134090-A (GB)
Title: Feeder
Inventor: DOERMAN ERYK STEFAN
IPC: B65G27/32
Filed: 1983-01-06
Abstract: In order to feed diamonds 10 in succession with increasing gaps between the diamonds, a horizontal feed member 32 having a groove is oscillated both up and down and in a direction parallel to its discharge end portion 34. The receiving end portion 33 of the feed member 32 is curved through about 60 DEG . As the diamonds 10 progress along the groove, the amplitude of the horizontal component of oscillation increases whilst the vertical oscillation remains the same. There are suspension springs 36 arranged so that the diamonds 10 are lifted upwards and forwards and then jump as the feed member 32 is returned to its initial position. In this way, the diamonds 10 progress along the feed member, gradually opening up along the curved portion 33. In a development of the invention, a counterbalancing arrangement can be provided by fixing the power source or electromagnet 38 to the middle of the springs 36 and having a counterweight on the other side of the electromagnet 38 to the feed member 32 with the effective mass or effective moment of inertia equal to that of the feed member 32. <IMAGE>

Title: Determination of the time or distance for motor vehicle servicing
Inventor: FRITZ RAINER
IPC: F16D66/02
Filed: 1983-08-25
Abstract: In order to determine the time or distance at which a motor vehicle should be serviced, the existing condition of motor vehicle parts prone to wear, e.g. brake and clutch linings, is monitored by measuring apparatus 2, 3. These measured values are fed to a computer 1 in which they are multiplied by weighting factors depending on the load. The computer calculates the length of life to be expected of the motor vehicle parts by comparison of the preexisting wear with a predetermined wear and value and indicates the same on an indicating apparatus 12. Other data taken into account by the computer are cooling oil or water temperature, 4, and engine speed, 5. <IMAGE>

Title: Permeable bag containing bleach
Inventor: TAI HO TAN
IPC: C11D3/39
Filed: 1985-04-25
Abstract: A bleach product for use in the washing machine as an adjunct to a normal detergent powder or liquid comprises a closed bag containing a particulate bleach composition, the bag being formed of sheet material having pores large enough to render it water-permeable but small enough to confine the bleach composition within the bag. The bleach composition comprises sodium perborate with an activator : such as tetraacetyl ethylenebiamine or sodium octanoyloxybenzene sulphonate. Preferably at least 25 mole per cent of the perborate is in monohydrate form: this gives reduced malodour development on short storage.

Title: A system for preventing the loading of non-authorised cassette copies of a computer program
Inventor: HALLIWELL ALAN KEITH
IPC: G11B23/28

Title: Liquid distributor for a mass transfer column
Inventor: BLATTER EDUARD
IPC: B01D3/00
Filed: 1985-08-14
Abstract: The liquid distributor consists of several channels (1) disposed horizontally alongside one another, to which the liquid is supplied by a pre-distributor. The outlet openings for the liquid are formed by vertical slits (11, 12). One edge of the slit lies along the plane of the side wall (2, 3), the other is formed on a part (9) separated by two vertical sections from the side wall (2, 3), and bent outwardly out of it. The slits (11, 12) are disposed in a row in the upper part of the side wall (2, 3) and somewhat wider apart one from the other than from the bottom edge (14) of the side wall (2, 3) the distance between the slits (11, 12) being more than ten times the width of the slits. The bottom edges (14) of the side walls (2, 3) protrude over the bottom of the channel (4) and are zig-zag shaped. The liquid flows out of the slits (11, 12) approximately horizontally (21, 22) along the side walls (2, 3), fans out in the longitudinal direction of the channel far above the side walls (23, 24) and drips from the serrations (19) of the bottom side wall edges (14). <IMAGE>

Filed: 1985-08-21
Abstract: Pristine optical fibre is drawn at high speed through a coating apparatus having, in series, an overflow reservoir (5) an orifice member (6,7) a low pressure reservoir (R3), another orifice member (8) a high pressure reservoir (R1) and, finally, a sizing orifice (16,17). A needle valve controls the pressure applied to the lower pressure reservoir in order to achieve the desired overflow in the overflow reservoir, to compensate for varying viscosities of coating materials. Low-friction material is used at least for the overflow reservoir and the orifice members (7,6). <IMAGE>
Patent GB-2164718-A (GB)
Title: Mole
Inventor: YARNELL IAN ROLAND
IPC: E21B7/30
Filed: 1985-09-19
Abstract: A method of lining an underground duct includes towing an assembly of duct enlarging apparatus (10) and lining pipe sections (14) through the duct (12) by passing a chain (18) through the whole assembly and attaching it to a plate (42) placed over the rearmost pipe section (14A). In this way, tensile overloading of the joints between the pipe sections (14) due to frictional contact of the sections against the wall of the duct (12) is avoided. As the assembly is moved through the duct (12), new pipe sections (14) are periodically attached at the rear by releasing the tension on the chain (18), removing the plate (42), threading the chain (18) through the new section (14), and replacing the plate (42). To reduce snaking of the lining pipe when under compression, a clamp is included inside the leading apparatus to clamp the chain (18) and limit the compression of the pipe sections (14).

Abstract: A locking device (e.g. for use as a vehicle steering lock) has a locking bolt 3 operable by a plastic card encoded key inserted into chamber 10. A latch (not shown) is provided to retain the locking bolt in a locked position (shown) until a sensor 16 reads and verifies information stored on the encoded key as the key is inserted. A solenoid then disengages the catch to allow the key to operate the locking bolt by pushing a member 9 which causes a cam 6 to rotate on axis 5 and engage a bolt projection 7. <IMAGE>

Title: Transit for cables and pipes
Inventor: TWIST MICHAEL
IPC: F16L5/02
Filed: 1986-02-11
Abstract: In a lead-through transit for cables or pipes 3 of the kind in which a series of modular resilient blocks 4 or blanks 5 are mounted in a frame 1 through which the cables 3 extend, the invention is directed to the compression and packer assembly 7 by which the opening through the frame 1 is closed and pressure applied to the assembled cables 3, blocks 4 and blanks 5 with stayplates 6 between each row of blocks. The compression and packer assembly 7 comprises a rigid plate 8 which seats on the assembled blocks 4 and blanks 5 for engagement by a compression bolt 33 mounted on the frame 1 to apply a load to the plate 8. Three resilient packer blocks 9,10 and 11 are arranged to be inserted between the plate 8 and frame 1 with two of the blocks 9,11 being for insertion on either side of the bolt 33 and having respective distance members as rods 28 to limit the reactive effect of the assembled blocks 4 and blanks 5 with cables 3 so that the compression bolt 30 can be displaced clear of the centre of the frame 1 to leave a clearance space into which the centre packer block 10 is inserted. Each packer block 9,10 and 11 has an associated compressor stud 12,13 and 14 which acts to compress it's block thereby expanding the packer blocks into tight sealing engagement between and with the plate 8 and the frame 1. The arrangement of the compression and packer assembly ensures improved sealing of the transit and is simpler to handle and assemble than prior arrangements.
