Title: Reducing friction between relatively rotatable members
Inventor: BRADSHAW WILLIAM
IPC: D21F5/14
Filed: 1981-11-10
Abstract: The invention is concerned with a method of sealing against the ingress or egress of fluid across the end of a roller. The roller 256, 258 or 260 has a stub axle 20 received in an open- ended slot 12, 14 or 16 in a stationary wall 10 of the apparatus, a lubricating port 26, 28 or 30 is provided in the wall facing an end face of the roller and there is means for supplying a lubricant under pressure into the port, the relationship between the impedance between the end face of the roller and the wall on the one hand, and the pressure of the lubricant supply on the other hand, being such that the lubricant is able to flow radially outwards over the end face of the roller. In the preferred arrangement the port is kidney shaped and substantially concentric with the roller axis. In fact, the port may subtend a considerable part of a circle providing that its ends do not break out into the slot.

Patent GB-2106400-A (GB)
Title: Adjustable exercising apparatus
Inventor: KIEF HORST
IPC: A63B21/008
Filed: 1982-08-24
Abstract: The apparatus comprises a piston 1 movable by a rod 3 in a cylinder 2 which has at each end a pressure relief valve 5. Sleeves 12, which each comprise an annular groove 15 and an axial slot 13, are rotatable about the cylinder 2 to align the slot with one of a series of apertures 11. As the piston 2 is moved to the left (as shown) the air pressure builds up and is partly relieved by the valve 5. When the piston passes the aperture aligned with the slot 13 the air in front of the piston rushes via the bypass groove and slot to the rear of the piston. Two such units may be linked in tandem. <IMAGE>

Title: High density packaging for electronic circuits
Inventor: SCARLETT JOHN ALAN
IPC: H05K3/36
Filed: 1982-09-03
Abstract: A high density assembly of integrated circuit units is made on a flexible or flexi-rigid substrate of insulating material which consists of flat sections (13) carrying the IC units separated by flexible portions. Each flexible region carries contact fingers or strips (4), so located that when the substrate is folded into a corrugated form the contact fingers or strips are on the outside of the now curved flexible portion. The substrate is either folded back on itself, or a number of such substrates placed adjacent to each other, with contact fingers or strips on adjacent flexible portions engaging. Compliant spacers (14) located between the inner or concave sides of the substrate urge the contact fingers into engagement. The whole is in a box and can be filled with a liquid coolant. Contact fingers may also be provided on the inner or concave sides of the flexible portions. In such case the compliant spacers (14) also have contacts to cooperate with these contact fingers. <IMAGE>

Title: Liquid wave energy absorber
Inventor: AMBLI NILS
IPC: F03B13/14
Filed: 1982-09-28
Abstract: For liquid wave energy absorbers, it is proposed that confining surfaces be placed adjacent the absorber, optionally secured to the absorber, in such manner that the band width of the dependency of the energy absorption on the wave frequency obtains at least one new maximum at a frequency determined by the placement of the confining surface. The principle is explained in connection with a wave energy power plant which operates according to the oscillating water column principle and which is made as a concrete structure with a submersed opening 7. In front of the opening 7, wall projections 10 are arranged which act as confining surfaces. <IMAGE>
Patent GB-2112236-A (GB)
Title: Digital device for clock signal synchronization
Inventor: BODY GERARD JACQUES MARIE
IPC: H04L7/033
Filed: 1982-10-29
Abstract: A phase lock loop circuit for synchronizing clock signals HSYN, locally generated by a controlled oscillator 9 with respect to a received reference clock HREF comprises a digital phase comparator 1-3 for assessing the phase difference between the local clock and the reference clock and furnishing the mean value of the voltage indicative of said difference, and means 7 for storing the last instantaneous phase difference as soon as a pulse of the reference clock HREF is lost. Phase comparison of HREF and HSYN is achieved by adder 3 fed by up-counter 1 and down-counter 2. A register 7 stores the instantaneous output from adder 3. Circuitry 6 directs loss of HREF whereupon a multiplexer 8 transmits the stored value of phase difference to D-A converter 4 and oscillator 9. Up-counter 1 remains blocked after restoration of HREF until a comparison circuit 69 determines that the instantaneous and stored phase differences are equal. <IMAGE>

Title: Continuous production of adhesively secured cartons
Inventor: KNOTTS JOHN MARTIN
IPC: B31B3/32
Filed: 1982-11-19
Abstract: In a method of continuously producing cartons of the same type but of different depths, a strip (29) of cardboard is supplied automatically to a set of friction rollers (44) which advance a preselected length of strip dictating the eventual depth of a carton. Simultaneously with advancement of the strip (29), creasing discs (54) provide longitudinal creases defining at least side panels of the carton Thereafter, successive carton blanks are severed and creased by a tool head (60) and each blank is advanced to one of a plurality of formers (84) mounted on arms (83) on a rotatable indexing hub (82). Various ploughs and pressure pads fold the carton blanks with adhesive being applied and the eventual erected, adhesively secured cartons are ejected from the formers onto a guideway (98). To change the depth of the cartons, controls vary the length of the strip advanced past the tool head (60), the folding and erection arrangements being common to a range of carton sizes. <IMAGE>

IPC: F24F3/16
Filed: 1985-02-11
Abstract: Apparatus for ionising air, for example for feeding to a boiler to act as a catalyst, comprises a closed container (15) which is divided into two chambers (17, 18). Water is fed under pressure to atomising jets (21,22) which produce a mist inside each chamber. Air is fed by a pump (28) into the first chamber and passes upwards through the mist in that chamber, through an aperture (20) near the top of a partition wall (19) and downwards through the mist in the second chamber. The thus-ionised air leaves the second chamber via an outlet pipe (30) and passes through a demoisturising coil (31). The water for feeding to the jets is contained in a reservoir (2) at the bottom of a casing (1) in which the container is mounted.
