Title: Force measuring instrument
IPC: G01G3/08
Filed: 1957-12-09
Abstract: 829,252. Electric measuring systems. JOHNSON, C. Dec. 9, 1957 [Dec. 12, 1956], No. 38174/57. Class 40 (1). [Also in Groups XIX and XVIII] A force measuring instrument comprises a rigid base 11, a platform 26 pivotally connected thereto by flexure plate means 27, 28, flat resilient means 48 connected to the base 11 and having a portion of its length freely bendable and connected by a direct force transmission element 47 to the platform 26, the resilient means 48 resisting pivotal movement of the platform. The platform 26 is pivoted by means of the flexure strips 27, 28 to a fixed wall 20, the other end of the platform being just above a second wall 19. The free end of the platform 26 is connected by a stud 47 to the free end of a leaf spring 48, the stud 47 having notches 58 to allow for flexing to compensate for inaccurate alignment of the free ends of the platform 26 and spring 48. Movement of the spring 48 and the platform 26 is sensed by a differential transformer 62, the armature of which is connected to the platform 26 by an adjustable screw 66. A rough adjustment of the free length of spring 48 and hence of the range of the instrument can be made by moving a clamp block 55, screws 57 being inserted in various threaded bores 24 in the base 11. A further finer adjustment can be made by sliding other clamp blocks 53, 54 when screws 57 have been loosened. A fine adjustment of the zero position, to ensure that the platform moves only between limits defined by the head 42 of an adjustable screw 41 and the top of the wall 19, is made by use of a sleeve 44 threaded both internally and externally and having a hexagonal head 45. Other embodiments described include one in which the free length of the spring 48 is fixed, no range adjustment being possible, one in which the spring 48 is bent at right angles at its free end and extended, to take the place of the stud 47, and one which is provided with a waterproof casing. The differential transformer may be replaced by a strain gauge or pneumatic measuring means, a threaded bore 68 being formed in the wall 20 for the insertion of an air conduit in the latter case.

Filed: 1961-10-26
Abstract: 922,389. Hopper discharge. ALGEMENE KUNSTZIJDE UNIE N.V. Oct. 26, 1961 [Oct. 31, 1960], No. 38421/61. Class 78 (1). A valve 50 for controlling the discharge of material from hopper 2 has two valve parts 25, 29 and is operated by handle 13 acting through lever 10 and stem 7. The position of handle 13 is defined by the engagement of wedge 20 with either of notches 18 or 19. In use, the operator swings handle 13 from the valve-open position at stop 17 anti-clockwise to insert the wedge 20 into notch 19, as shown. This lowers the first valve part 29 into contact with the hopper inside surface, as shown, to prevent discharge. The operator then moves the handle so that wedge 20 lodges in notch 19. This causes the second valve part 25 to move against spring 30 into engagement with the hopper inside surface. In this way, the first valve part screens the second valve part, and allows it to close the hopper free from obstruction.

Abstract: 1435596 Luminescent screens TOKYO SHIBAURA ELECTRIC CO Ltd 16 Aug 1973 [21 Aug 1972 23 Aug 1972] 38667/73 Heading H1D A method of making a striped cathodoluminescent screen for a colour c.r.t. comprises irradiating a concave shadow mask having elongate apertures separated by bridge portions using a source of sufficient effective length to produce on a radiation sensitive film a continuous image for each row regardless of bridge portions, and vibrating the source in a direction having at least a component perpendicular toits longitudinal axis to at least partially compensate for diffraction. The guns may be "inline" and the phosphor stripes separated by light absorber and narrowing at screen ends horizontally from the centre. Three types of irregularities are considered: (i) those appearing in all parts of the screen, (ii) those appearing gradually in the corners due to non-parallelism of source and mask at all points and/or (iii) those appearing opposite the mask bridging portions, these being discussed in relation to source dimensions. Some compensations require a source width > 1 mm. which produces diffraction i.e. a type (i) irregularity (Figs. 6, 7, not shown) which is reduced by the source vibration (Fig. 9, not shown). Fig. 10 (not shown) includes high P Hg source (54), slender window (55), pivoted arms (56-58) and cam (60) producing the vibrations. Type (ii) uneveness may be reduced by inclining the source to the mean value of the inclinations (cf. Fig. 11, not shown) for each elementary area (65) (Fig. 12, not shown), e.g. byapparatus (Fig. 13, not shown) with shield (68) with end on elongate slit (67) and moved along the Y-axis by motor (69) and lever (71), light source (35) being synchronously inclined about shaft (74) so that source and area (65) remain parallel. Figs. 10 and 13 apparatus are combined in practice. Type (iii) uneveness may be substantially eliminated by sources with windows as in Figs. 14A-14C (not shown). Absorbing and phosphor stripes may be laid in either sequence and a shadow mask with reduced apertures may be used for screen fabrication. Mask, stripe and source dimensions and vibrating amplitudes and periods are given.

Abstract: 1,097,079. Knitting - machines. TEXTILE MACHINERY DEVELOPMENTS Ltd. Dec. 8, 1966 [Sept. 10, 1965], No. 38672/65. Heading D1C. A unit is provided for converting a straightbar plain machine to a rib machine and comprises a bar 37, 38 of machine needles 39 mounted between a framework 18, 19 which contains the mechanism for operating the machine needles and associated knocking over slide 84, the framework being readily attached to the horizontal template bar 1 and to the handwheel shaft 17 of the machine. When it is desired to convert the machine to rib knitting the unit is mounted on the hand-wheel shaft 17 and secured to the template bar 1 by means of clamps in the form of bearer elements 28 which are adjustably attached to the inner plates 18 of the framework. The framework comprises spaced inner and outer plates 18, 19 between which the mechanism for operating the machine needle bar is mounted. The needle bar is secured to a support bracket 35 the ends of which are attached to brackets 46 slidably mounted on a slideway 49. The brackets 46 are attached to a connecting rod 58 which is secured to a lever 61 adapted to be actuated by a cam on an auxiliary cam shaft driven from the main cam shaft of the machine with the effect that the machine needle bar is given an advancing and withdrawing knitting movement. Simultaneously the brackets 46 which are secured to levers 52 are raised and lowered to effect a pressing movement of the beards of the needles with the underside of the sinker bed. This latter movement is achieved through levers 71 pivoted at 72 being raised under the influence of a cam on the auxiliary cam shaft causing the levers 71 to engage a rod 55 eccentrically secured between the two brackets 52. Rotation of the rod 55 permits adjustment to be made to the pressing movements of the needles. In addition a knocking over slide 84 for assisting in the formation of the rib fabric is advanced and retracted by lever mechanism operated from a cam on the auxiliary cam shaft. When plain knitting is being produced on the frame needles only, the cams operating the machine needles and the knocking over slide are shogged such that the cam followers rest on idler or bluffing cams and the machine needles and mechanism remain inoperative. To permit rib knitting to be produced the intermediate frame needles are rendered inoperative by the provision of masking blades 119 mounted on a bar 118 capable of being manually manipulated to a lower operative position or a raised inoperative position. In addition they are capable of adjustment forwards or backwards to enable the quality of the fabric to be adjusted. Manually operated or machine operated loop transfer elements are provided to transfer loops from the machine needles to the frame needles on completion of rib knitting. A leather insert may be provided between the two halves 37, 38 of the machine needle bar to enable the needles to be firmly gripped.
