Patent GB-585070-A (GB)
Title: Hydraulic press
IPC: B30B15/16
Filed: 1944-11-21
Abstract: 585,070. Hydraulic presses. PAGE, H. E. Nov. 21, 1944, No: 23139. [Class 69 (ii)] A hand-operated hydraulic press has a fixed main piston 33 in a ram 25 also containing the liquid reservoir 28. The approach stroke may be made mechanically by turning the handcontrol wheel 90, this forcing down the piston rod 29 through gearing. Alternatively the approach strike is made hydraulically by oscillating the wheel 90, when fluid is pumped into the cylinder 26. When the work is contacted fluid press rises, unseating a valve in ram base and allowing fluid to pass to the main ram cylinder 27. The shafting from the wheel 90 contains a clutch 100 under foot control, first movement of which de-clutches and then allows the piston 29 to retract if necessary; subsequent for movement unseats a valve in the ram base'to allow the main ram to retract under spring pressure. The handcontrol wheel is duplicated, one on each side of the press.
Patent GB-405714-A (GB)
Title: Improvements in the cleaning of filters
Filed: 1932-08-18
Abstract: In cleaning a filter bed by simultaneous air scour and upwash, the dirty water resulting from the upwash is stored above the bed until the air scour has ended and then discharged, the removal of extracted dirt being completed by a surface flush of water. Alternatively, only a small volume upwash is used during the air scour and the cleansing completed by a flush without air scour.  A filter bed having a horizontal surface may be cleansed by a flush discharged close to and sweeping across the surface of the bed in sufficient volume to carry away the dirt into an oppositely situated wash-out channel, the collecting lip of which is only a sufficient distance above the surface of the bed to prevent the sand being washed away.  The water for a surface flush may be supplied from a conduit with apertures directed against an end wall of the filter, the water falling on to a deflector projecting from the wall below the conduit and being directed across the bed. Any of the sequence of operations may be performed automatically. For example, when wash water is stored above the bed, the closing of the air valve may cause the wash water outlet valve to open. Specification 196,153, [Class 46, Filtering &c.], is referred to.

Title: Process and apparatus for the treatment of textile fibres
IPC: D06P1/22
Filed: 1954-08-12
Abstract: <PICT:0776983/IV(b)/1> A process of dyeing textile fibres, such as wool and rayon, in a closed liquid circulation system under static pressure at temperatures of at least 100 DEG C. consists in introducing superheated water into the system from a heated tank 35, causing this water to circulate through the fibres placed in an autoclave 1, and finally adding the dye through a funnel 16 in an expansion vessel 13.  The dyes used may be vat dyes in a non-reduced state with caustic soda and hydrosulphite, or vat dyes in a leuco state, or substantive, sulphur, naphthol, acid or acetate dyes.  In detail, the apparatus comprises a closed circulation system having an autoclave 1, a sampler 26, which may be closed off from the system by valves 29, 30, an expansion vessel 13 connected via valve 19 and pipe 18 to a source of compressed gas, a heat exchanger 10, a pump 4, a valve 5 for reversing the circulating flow, and a water-tank 35 provided with a heater 36.  In operation, all valves communicating with the atmosphere except the vent 2 are closed.  Valve 34 is then opened gradually, so that the liquid circulates and the pump 4 is started, the valve 2 being closed as soon as liquid escapes from it. An air cushion is maintained in the vessel 13 to provide a static pressure, and steam may be passed through the heat-exchanger 10 to raise the temperature of the liquid.  When all the dyestuff is to be added quickly to the bath, valve 23 is opened and valve 24 shut.  If dyestuff is to be added at a pre-determined rate, valve 23 is closed and valve 24 opened, so that dye enters through the regulator 25. Compressed gas may be allowed to enter the vessel 13 through the valve 19 to prevent cooling of the liquid, the pressure reaching nearly two atmospheres.  When the operation has been concluded the bath may be cooled by passing cold water through the exchanger 10. In a modification the dyestuff may be pumped or injected into the system at a definite rate.  A second expansion vessel may be provided in the system to prevent the setting up of overpressures and the vessel 13 may be made large enough to act as a container for heating the bath.

Title: Still colour television signal recording and reproducing apparatus
IPC: H04N11/00
Filed: 1976-06-07
Abstract: 1535601 Colour television SONY CORP 7 June 1976 [12 June 1975] 23459/76 Heading H4F A still colour television picture signal is recorded and reproduced without loss of the colour burst by writing into a storage tube signals from one field or frame and continuously reading out the stored signals, the scanning lines in the storage tube beginning at or just before the colour bursts so that they are recorded at or near the beginning of respective horizontal scanning lines. As described the television signals Sa from source 1 are applied to a low pass filter 2 and a band pass filter 4 for respectively separating out the luminance and chroma signals, the chroma carrier being converted at 5 to a frequency (equal to an integral multiple of line frequency, derived at 12) suitable for recording, and added to the luminance signal at 3 to give a modified video signal Sm. Horizontal and vertical synchronizing pulses are filtered out at 14, 18 respectively and are used to synchronize horizontal and vertical deflection circuits 17, 19. The horizontal sync pulses are delayed by nearly a whole line (Figs 2B, 2C, not shown) at delay 16 so that when the modified video signal is written into the storage tube 7 the colour bursts appear down the left hand side of the target and the right hand edge of the picture is lost (Figs. 2E, 2F, not shown). When the stored signal is read out by circuit 9 the luminance and chroma signals are filtered out at 21, 27 and the chroma carrier is restored at 28 to its original frequency. Luminance Sy is clamped, 22, to a pedestal level and is added to the blanking and synchronizing pulses 23, 24 respectively and to the chroma at 25 to give a composite video signal So representative of a still picture to be displayed at 50.
Patent GB-429014-A (GB)
Title: Improvements relating to variable speed power transmission systems
IPC: F16H61/664
Filed: 1933-08-23
Abstract: 429,014. Variable-speed gearing. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Hayes, F. H.; Middletown, New Jersey, U.S.A.) Aug. 23, 1933, No. 23497. [Class 80 (ii)] In variable-speed power transmission mechanism of the torque-responsive torus disc and roller type such as is described in Specification 392,589, means are provided whereby an unwanted spontaneous change in the gear ratio resulting from slackness in the end mountings of the roller carriers 253 and occurring when the vehicle or other normally driven part tends to drive the engine or driving member, is obviated or compensated for. The carrier 253, Fig. 2, has an adjustably mounted socket 23 at one end embracing a transverse ball end on the rocker 248<a> and a ball end 24 at its other end slidable in the hole 19 in the rocker 248b so that relative axial movement with respect to the rocker 248<a> is precluded and with respect to the rocker 248<b> is allowed. A modified form is also shown in Fig. 2 in which the socket is closed by a screw plug 23<a>, Fig. 2. This relative movement of the carriers with respect to their left hand rockers causes an upward change of gear giving a " free-wheeling " sensation to the driver so that the engine has to be speeded up before it can resume its drive. The constructions above described obviate this " raised gear " effect. Means for compensating for the above effect can be embodied in the hydraulic control mechanism described in Specification 398,582 and comprise an additional ported sleeve 29, Fig. 1, with a pressure-equalizing bleed-hole 29<a> mounted between the control. piston 32 and the adjustable sleeve valve 315 In the normal arrangement, oil pressure moves the piston 32 against a spring 196 to operate a lever 324 which through segmental gears 9, 10, a compound rocking beam 233, links 236, a spider 238, and a control cam 246 actuates the rockers 248. A valve 26 guided in the sleeve 29 and normally closed by the lever 324 opens on easing the driving effort, and the oil pressure above the piston 32 is relieved by the downward movement of the sleeve 29. The spring 196 is thus able to move the piston 32 to effect a gear change equal and opposite to that produced by slackness between the rocker and carrier parts. The sleeve 29 is pushed against a stop 30 by a spring 27 and has a lower stop in the form of a sleeve 28. The piston 32 is prevented from rotating by a tongue 324<a> engaging a gap in a ring 32<a>. This latter part of the invention is applicable to other forms of continuously-acting servomotor, such as that described in Specification 397,875. Specification 344,062 is referred to in the Provisional Specification.

Title: Improvements in shock absorber
IPC: F16F9/516
Filed: 1945-09-13
Abstract: 605,723. Hydraulic shock absorbers. GABRIEL CO. Sept. 13, 1945, No. 23652. Convention date, Jan. 9. [Class 108 (iii)] In a fluid shockabsorber of the kind described in Specification 595,806, comprising a passage or passages 35 extending from end to end of a head portion 33 of a piston on which is mounted a packing element 50 having a carrier 51, movable during the recoil stroke to a position to close the passages 35 and during the impact stroke to a position in which the passages 35 are open, the head 33 and carrier 51 have co-operating portions which positively limit movement of the carrier 51 on the recoil stroke. The piston has a portion 34 of reduced diameter on which the carrier 51 and packing element 50 are slidable, being urged by a spring 52 to engage the radial annular surface 33a between the portion 34 of the piston and its main head portion 33. The ring 50 in its unstressed state is of circular section and its diameter is greater than the length 51a of the axial portion of the carrier 51, so that on commencement of the recoil stroke, the ring contacts the surface 33a before the carrier 51. Axially extending peripheral grooves 43 on the piston portion. 34, communicate by respective passages 44 with a bore 39 of the piston which opens into a counterbored portion 36 in the head 33. Flow through the bore 39 is controlled by a spring-loaded valve 55 which co-operates with a seating 40 slotted at 41, and is centred by a stud 54 carried by a cup-shaped member 53 threaded within the counter bore 36. Projections 58a of a member 58 extending through openings in the member 53 engage recesses in a closure member 24 of the cylinder in the collapsed position of the shock absorber to enable the spring 56 of the valve 55 to be adjusted by rotation of the piston and piston-rod causing relative rotation of the member 53. A plate 45 forming an abutment for the spring 52 is secured to the piston-rod 19 by means of a pear-shaped slot 46, Fig. 4, having a larger offset portion 46<SP>1</SP> allowing the plate to slide along the piston-rod into the correct axial position from which it is then displaced transversely so that a smaller and concentric portion of the slot 46 engages a groove 32 in the piston. The offset opening overlies one of the grooves 43, and further openings 47 in the plate 45 overlie the remaining grooves. The cylinder communicates through the closure member 24 with a reservoir 23 surrounding the cylinder, by means of a fixed orifice (not shown) in the member 24 and also by a self-centering valve 62 loaded by a spring 64 which is secured at one end to the valve stem 63.

Patent GB-1493393-A (GB)
Title: Fluid curable compositions containing particulate fillers and composite polymeric materials obtained therefrom
IPC: C08L51/02
Filed: 1974-05-29
Abstract: The mixture contains an organic liquid which is polymerisable to form a solid polymer and whose viscosity at the moulding or forming temperature of the mixture is not more than 5 Pa.s. Dispersed in this liquid by means of a polymeric dispersant are finely divided particles of at least one inorganic filler in a proportion of at least 20 % by volume, if desired up to 90 % by volume, based on the total volume of the mixture. The dispersant keeps the filler particles in the polymerisable liquid in the state of a stable, deflocculated dispersion. The dispersant has in the molecule at least one chain-like component which is solvated by the polymerisable liquid and additionally contains at least one grouping which is capable of association with and attachment to the filler particles. The mixture is prepared by dispersing the particulate inorganic filler in the polymerisable organic liquid in the presence of the polymeric dispersant. Owing to the low viscosity of the mixture, it can be made into complicated shapes simply by casting and then be cured to form corresponding shaped articles composed of a composite multicomponent material in which the particulate inorganic filler is dispersed as a reinforcing material in an organic polymer matrix. Mouldings constructed in this way are obtainable in a simple manner and exhibit improved mechanical properties.
