Patent GB-343119-A (GB)
Abstract: 343,119. Ink-ribbon mechanism. SETRIGHT, H. R., 53, Downs Road, Clapton, London. Nov. 2, 1929, No. 33414. [Class 100 (iv).] A portable ticket-printing machine incorporates mechanism for the spring feed of ink ribbon instead of positive feed to prevent damage to the ribbon when the delivery bobbin becomes exhausted. The ink ribbon 68 is wound round two bobbins 69, 70 formed with a spindle 71 at each end and two holes 72 in each flange, the spindles 71 at one end of the bobbins engaging in boxes 75 in ratchet wheels 73, 74 having projecting pins 76 for engaging in the holes in the flanges; the other spindle of the bobbin 70 engages in a boss in the plate 17, Fig. 6; the other spindle of the bobbin 69 engages in a bore 77 of an indicating disc 78 carrying an indicating projection 80 and having a pin 79 passing into one of the holes 72 so that the disc rotates with the bobbin. Movement of the :ink ribbon is effected during rotation of the shaft 54 by means of the double barbed pawl 81 on a shank 83a fixed to the cross-bar 84 urged downwards on to the shaft 54 by springs 86 and co-operating with a pin 85 on the snail cam 56 to be raised upwards on rotation of the shaft 54. The pawl 81 is moved into co-operation with the desired ratchet wheels 73 or 74 by means of the control slide 82 with which engages the spring wire 83 fixed at 84a to the shank of the pawl and which moves the pivoted double-ended non-return pawl 87 into engagement with the desired ratchet wheel by means of the spring-pressed ball 89 mounted in the slide 82 engaging with one or other of two depressions in the top of the pawl on either side of its pivot 88.

Abstract: 969,958. Pipes; junction pieces. C. S. GALE. Feb. 28, 1962 [Jan. 7, 1961], No. 34467/60. Headings F2G and F2P. In a liquid circulation system a pipe comprising two bores 8, 9 is fabricated from a single strip of material bent into an S formation, the two bores being separated by a common central portion 3 of the strip. In the construction shown the outer portions of the strip are rolled over or bent in opposite directions and their free ends secured as by welding at 6, 7 to the edge of the central portion of the strip. When two tubes as shown in Fig. 2 are joined the housing of bore 8 is cut back so that the two lengths of the housing of bore 9 may be welded, a shaped piece then being welded into the gap left in the housing of bore 8 (Fig. 5, not shown). Two valves 21, 26 may be introduced into a pipe, the former by sealing bore 8 and welding two pipes 18, 19 into the bore and the latter by welding two pipes 27, 28 to bore 9. The ends of pipes 27, 28 engaging with the valve may be circular in cross-section. The material of the pipes may comprise steel, aluminium or an alloy thereof, or a synthetic plastics material, the fabrication process being continuous.

[Also in Group XXIII] Glass, particularly fibre, while still in a heated and formable condition, is passed through an electrostatic field and allowed to cool while still under the influence of the field. The roughening of the surface thus produced becomes permanent on the completion of the cooling and solidification of the glass and makes the glass more durable and resistant to abrasion; the adhesion of sizing or lubricating materials or of binders or metallising coatings is also improved. In the form shown, fibres 63 being attenuated from nozzles 61 pass between high voltage electrodes 64 and, for metallizing, then pass before guns 65 discharging metal particles from a wire 66 having the same polarity applied thereto as to the electrodes 64, i.e. opposite to that established in the fibre. The coating metals may comprise copper, brass, molybdenum, tungsten, nickel, steel, aluminium, zinc and tin or alloys thereof. Instead of passing the roughened fibres before metallizing guns they may be drawn through molten metal.

All the wefts d extend over the warps c and form them into loops, which extend into and brace open the meshes of the fundamental fabric. As shown in Fig. 5, fabrics comprising two or more layers of warp and weft threads may be combined by the additional threads c, d, which in this case form a complete fabric. The threads c, d may be of different materials, thickness, twist or colour to the threads a, b and may comprise animal vegetable and mineral fibres. The number of threads c, d may be less than that of the threads a, b, so that the loops of the threads c may only enter certain of the meshes of the fabric a, b and thus produce fabrics with strips or squares denser or more porous than other parts of the fabric, thus producing designs &c. These may also be produced by weaving the additional threads into the fundamental fabric in the manner described in portions only, and interweaving them in the ordinary manner in other portions of the fabric.

Standard sample signals are held in sample and hold circuits 32-34. The optical property monitored is colour and wavelengths # 1 , # 2  are selected within the range 340-450 nm. whilst # 3  is selected far enough into the red region that it is virtually insensitive to reflectance change due to presence of impurities in the sample. The first indicator value # 1  equals k times R# 3  minus R# 1 . The second, # 2  = k [R# 3  - (R#1+R#2/2)]. The third, # 3  = k (R#1 + R#2 + R#3/3). Indicator value # 1  is said to be sensitive to changes in the near ultraviolet and to be largely insensitive to differences in particle size. Indicator value # 2  relates to average reflectance in the blue region.

Title: Controller for fluid pressure operated devices
IPC: B62D5/097
Filed: 1975-09-03
Abstract: The control unit is suitable for power-steering systems of motor vehicles. It contains in a housing (53) a rotatable main valve element (77) and a sequence valve element (79), which are mutually adjustable to a limited extent in both directions relative to a neutral position. A movable member of a metering device (29) for the pressure medium flowing through is coupled to the sequence valve element. The control unit has a pressure-medium inlet (119), a pressure-medium outlet and a first and second control pressure-medium connection (123R, 123L) which are connected to a control cylinder (39). The housing forms with the valve elements a first pressure-medium passage arrangement, by means of which the inlet (119L) is connected via the metering device (29) to the first control pressure-medium connection (123R) when the valve elements are adjusted in the one direction, and a second pressure-medium passage arrangement, by means of which the inlet connection (119R) is connected via the metering device to the second control pressure-medium connection (123L) during a valve adjustment in the other direction. The two passage arrangements have, for the pressure-medium flows via the metering device, the same flow resistance during each adjustment of the valve elements, as a result of which a uniform response behaviour is achieved and precession movements of the steering wheel are prevented. <IMAGE>
