IPC: G01N21/51
Filed: 1964-02-03
Abstract: 1,019,216. Photo-electric scattered light measurement. BECKMAN INSTRUMENTS Inc. Feb. 3, 1964 [Feb. 26, 1963], No. 4411/64. Heading G1A. Apparatus for measuring scattered light comprises a sample cell, means for directing a beam of light thereupon, and photo-electric means movable adjacent the detector to measure the light scattered from a sample within the cell as a function of angle with respect to the incident beam. Light from a source 10, Fig. 1 is chopped at 11 and passed through a monochromator 13 to impinge on the sample cell 14. The cell comprises an inner container 42, Fig. 3, for the sample and an outer container 40 filled with liquid of similar refractive index. Rotatable about the cell is a plate 17 carrying a mirror 48 and a photomultiplier 16 to receive light scattered at various angles to the incident beam. A reference detector 15 receives light passing straight through the cell. The outputs of both detectors feed demodulators 23, 27, the signals from which actuate a recorder 31 through a differential amplifier 30. The output of demodulator 23 is used to adjust the width of the monochromator exit slit to maintain the incident light intensity substantially constant. By changing over switch 35, the slit is fixed, and the output of demodulator recorded against a fixed reference generated across a resistor 36. Three modes of operation are possible:- (1) A fixed wavelength,with the detector 16 scanning between 15 degrees and 150 degrees (2) Fixed detector and scanned wavelength (3) Fixed detector and wavelength the measurement being of the variation of scattering with time. In a modification Fig. 4, (not shown) two cells are provided, irradiated alternately, one containing a sample and the other a reference liquid and the outputs of two detectors moved round the cells in synchronism are connected through a commutator to the demodulators 23, 27.
Patent GB-896492-A (GB)
Title: Improvements in or relating to traversing spindle mechanisms
IPC: D01H1/00
Filed: 1959-02-09
Abstract: 896,492. Traversing spindle mechanisms. SACO-LOWELL SHOPS. Feb. 9, 1959 [Feb. 10, 1958], No. 4458/59. Class 120(2) The traversing spindle mechanism especially of a roving frame comprises a bobbin driving member which is reciprocated by means of the alternating relative rotational speeds of two coaxial driving shafts 30, 33, the member being rotatable relative to the shaft 33. The member comprises a shaft 31, which is splined to the shaft 30 driven from a shaft 46, fixed to a nut 34, which is internally threaded for reciprocation on the shaft 33 driven from a shaft 48. The speed of the shaft 46 decreases as a belt 106 is moved on the cones 100, 105 of a variable speed drive so that the roving is wound at a constant linear speed, this speed of the shaft 48 is alternately greater and less than the speed of the shaft 46 and decreases as winding proceeds, and the length of the traverse is gradually decreased to give a package with conical ends. A flyer 10 is rotated at constant speed by the shaft 44 which is driven directly from the main driving shaft 90. The shaft 90 also drives the ring gear 94 of a planetary differential 96, the cone 100 and bottom drafting rolls 104. The speed differential of gears 94 and 108 is transmitted through a pinion 110 and shaft 112 to the shaft 46 and to the ring gear 116 of a second differential 118. To reverse the traverse a pawl 148 is biased against one of two studs on a collar 154 fixed to a builder shaft 142, which is held against rotation when one arm of a builder dog 158 is engaged by a builder pin mechanism 164. When this mechanism clears the builder dog arm, the shaft 142 is rotated one half revolution through a gapped pinion 146 and operates a pivoted reversing lever 170 connected at one end to a collar 174 splined on a shaft 169 and carrying reversing gears 130, 132. The alternating rotation of the shaft 169 so produced also reciprocates the builder jaw 164 through the rack gear 165 and is transmitted to the sun gear 122. Rotation of the shaft 142 moves the belt 106 by means of gears 178, 180, a rack 186 and the retainer 107 and shortens the distance between the jaws 196, 198 by means of a pinion 188 and oppositely handed threads 192, 194. Reduction in the spacing between the jaws 196, 198 shortens the length of the traverse of the shaft 142 so that the motion of the pinion 136 controlling the speed of the shaft 48 is derived both from the gradually decreasing speed of the pinion 108 and the direction of rotation of the shaft 169. A rack 186 is operated through gears 178, 180 as the shaft 142 rotates, whereby the belt 106 is operated through a retainer 107 and the building jaws 196, 198 are moved together by threaded portions on a shaft 184 to reduce the lengths of the traverse.

Title: Improvements in or relating to the manufacture of rubbe holloware
IPC: B29C41/14
Filed: 1956-02-13
Abstract: 851,853. Moulding rubber articles. LANDAU, L. Feb. 12, 1957 [Feb. 13, 1956], No. 4484/56. Clss 87(2). Rubber holloware, such as balloons and gloves, is stripped from a closely fitting former by locating the article-charged formers 11 between at least two gripping members 15 which initially do not touch the articles, translating the members 15 to grip the articles, moving the members 15 and formers 11 relatively to one another to strip the articles off, translating the members 15 to their first position and removing the empty formers. In the form shown, rows of formers are brought between the gripping members 15 which are resilient pads of sponge rubber preferably with the surface skin removed. They are supported on blocks 16 which are moved towards and away from the formers 11 by pistons 17 of a pair of horizontal pneumatic rams 18. These rams are themselves mounted on the cylinders 20 of a vertical pneumatic ram 21 having fixed pistons 22 carried by vertical rods 23. The rams 21 operate to move the members in a vertical direction, thus stripping the articles from the formers. A pair of nozzles 24 directs a jet of liquid at the stem of each former near the article stem to loosen the latter. The injection of liquid may be followed by an injection of compressed air effected in an similar manner. In another embodiment, the gripping members are a pair of parallel cylindrical rollers driven in opposite directions by geared electric motors and carried by brackets connected to the pistons of the rams. In a modification, the rollers taper from end to end and their axes are set at such an angle that a parallel-sided gap is left between the rollers. The rollers may be built up of thin discs of resilient material threaded on to an axis and if desired separated from one another by distance washers. Normally the rollers will be arranged to grip a number of formers but if desired a pair of rollers may be provided for each former. Specification 668,382 is referred to.

Title: Improvements in or relating to transistor switching circuits
Inventor: WATTS THOMAS PERCIVAL PATERSON
IPC: H03K17/64
Filed: 1962-02-07
Abstract: 960,763. Transistor switching circuits. TECALEMIT (ENGINEERING) Ltd. Jan. 18, 1963 [Feb. 7, 1962], No. 4717/62. Heading H3T. A sequence timer comprises a number of transistors each rendered operative by the charging of a respective capacitor, the capacitors being normally charged but being discharged immediately prior to the charging period. The operation of switch SW1 causes timing capacitors CA-CN to charge and the subsequent momentary operation of button PB1 causes contact PBIa to operate a relay BL1. Contact RL1 provides a holding circuit and contact RL2 connects the supply to the collector electrodes. Contact PB1b discharges capacitor CA which, upon release of the button, commences to recharge, at a rate determined by the setting of a potentiometer R1A. The charging current causes transistor VTA is conduct and a relay RLA to operate. Contact RLA2 of this relay operates an external circuit while RLA1 discharges the timing capacitor CB of the next stage. When capacitor CA has charged the transistor VTA becomes non-conductive and relay RLA releases, removing the discharge path for capacitor CB. The operation is thus repeated along the chain, the last stage re-initiating operation of the first. The switching sequence can be terminated at any time by operating button PB2 or at any stage by opening the corresponding switch SWA-SWN. It is suggested that the interrelation of the stages could be varied to provide a different operating sequence.
