Abstract: 1,203,456. Optical apparatus. N.R.D ASLUND. Sept.25, 1967 [Sept.29, 1966], No.43418/67. Heading G2J. [Also in Division G1] In a device for scanning an optical image, e.g. for producing on the screen of an oscilloscope 32, Fig.5, an indication of the variation of light intensity of a spectral line along its length, light is reflected by fixed mirrors 14, 15, and movable mirrors 1, 2, so as to form the image at right angles to a slit 8. The mirrors 1, 2 are at right angles to one another and form an angle of 45 degrees with the plane 3 of the image, and on  moving them in a plane parallel to plane 3, the line image is moved across slit 8 so that the intensity, as detected by a photo-cell 9, may be fed to the Y plates of a C.R.O. 32. The X-plates are fed with a voltage indicative of the movement of the mirrors 1, 2. The latter are mounted on one bar 17 of a parallelogram support 17, 18, 19, 20, which is given a sinusoidal rotation about torsion shafts 22, 23, by electromagnetic forces generated by coil 26 on the bar 18 and fixed magnets 28. The output from pick-up 27 is fed via a phase shifting network 31 to the X-plates of the C.R.O. 32. In a modification, Fig.3 (not shown) the mirrors (1, 2) are mounted on a swing formed by a single cross-bar (5) and a pair of parallel pivoted end supports (6, 7).

Abstract: 1,219,064. Valves. BELL AEROSPACE CORP. 3 Sept., 1969 [17 Oct., 1968], No. 43628/69. Heading F2V. A control valve cuts off the supply of fluid to a load under fault conditions when the rates of flow to and from the load differ materially. The valve has a force generating means in both feed conduit 31 and return conduit 42, which means normally act oppositely on levers 39, 45 to maintain closure member 55 off seat 56. When the flow rate through conduit 40 drops sufficiently to cause lever 39 to be pivoted clockwise, the valve closes. The force generating means consist of fixed restrictions, formed by projections 38, 44 on the casing co-operating with movable pistons 36, 43, which produce pressure drops across, and thereby forces on, the pistons in proportion to the flow rates. Piston 36 also has a spring loaded ball closure 51 which forms a variable restriction to improve the linearity of the device (see Fig. 2a, not shown). In a modification (Figs. 3 and 4, not shown) fixed orifice (68) are incorporated in piston type variable restrictors (69) which are mounted in a casing remote from the closure member (75) which is actuated by a piston (76) acting on a lever (79) in opposition to a piston (101) which acts on a lever (93). A dash pot (81) damps movement of the piston (76).

Abstract: 1527779 Sensing sheets in a feed path PITNEY-BOWES Inc 25 Oct 1976 [11 Nov 1975] 44263/76 Heading B8R [Also in Division G4] A malfunction detector system for use with an article transporting machine, e.g. transporting letters has a plurality of sensors 51-54 arranged to be spaced along the feed path of the articles and to generate a signal on sensing an article and a plurality of shift registers 54, 58, 60, 62 each connected to a respective sensor. A "1" marker is initially stored in each shift register and is shifted successively through the register in response to signals from the respective sensor. Selected stages of registers connected to adjacent sensors are compared. In the embodiment stage n of the register connected to the upstream sensor is compared using a NAND gate with state n + 1 of the register connected to the downstream sensor. As shown in Fig. 2 stages A, B, C, D of register 1 are compared respectively with stages B, C, D, A of register 2 since both registers are connected to recirculate. During normal operation if the "1" in the upstream register is held in stage n the "1" in the downstream register is in stage n - 1. If there is a jam the marker in the downstream register will not advance from stage n and one of the NAND gates will produce a zero output to light a lamp and indicate an error when the marker in the upstream register reaches stage n - 1. Similarly if any of the sensors fail the marker is not advanced in the respective register and a NAND gate operates the light. The articles are fed from a stack by roller 16 and are advanced by rollers 18, 20 under the control of photocells. Each article may be weighed 24, sealed at a station 28 and printed with the correct postage 34. The articles are stacked using one or more rotating cams 40.

The resins used in particular examples include-  (1) and (4) phenol-formaldehyde, particularly including an excess of formaldehyde so as to be cured by heat alone,  (2) polyester, prepared by heating maleic anhydride, phthalic anhydride and propylene glycol and copolymerizing with styrene by catalysis with methyl ethyl ketone peroxide dissolved in dimethyl phthalate and a solution of cobalt naphthenate,  (3) phenol-furfural including an excess of furfural,  (5) epoxy resin (diglycidyl ether of Bisphenol A) cured at room temperature by diethylene triamine,  (6) melamine-formaldehyde resin.  Alternative resins are condensation products of an aliphatic organic compound having an ethylene oxide on at least one of its chain ends, such as epichlorohydrin, and an organic polyhydric alcohol or phenol having 2 to 3 hydroxy groups and preferably having 3 to 17 carbon atoms, such as Bisphenol A, Bisphenol C, glycerol and ethylene glycol.  Solid epoxy resins can be obtained by dissolving liquid resins in an organic reactive diluent such as allyl glycidyl ether, butylglycidyl ether or phenyl glycidyl ether.  Epoxy resins may be cured by aliphatic polyamines such as diethylene triamine, aromatic polyamines such as p,p1-methylene (dianiline), m-phenylene diamine, anhydrides such as phthalic anhydride or diaminodiphenyl sulphone.

Abstract: 1275495 Selective printing NATIONAL CASH REGISTER CO 23 Sept 1970 [6 Oct 1969] 45247/70 Heading B6F Hammer impressiom mechanism.-A hammer 28 of glass-reinforced nylon material is supported by a pair of leaf-springs 31. The hammer carries at one end a metal impact member 41, and at the other end a self-lubricating plastics contact member 42. A "pigtail" spring 29 passes through member 42 and is embedded in the hammer body material. The spring 29 engages a boot 22 on a solenoid arm 17 which initiates movement of the hammer when solenoid 54 is energized. The solenoid arm 17 rests on a back stop device 24, and a penetration control device 55 is provided having a stop member 45 which engages a surface 32 of the hammer to control the length of the printing stroke. During operation, the solenoid arm 17 moves a set distance, whereafter the hammer continues under its own momentum thereby stretching the "pigtail" spring 29. After printing and before the solenoid arm 17 has returned to its rest position, the "pigtail" spring has the effect of re-engaging the hammer with the solenoid arm. Kinetic energy is absorbed by the resilient energyabsorbing stop members 33 and 39 adapted to engage the leaf-springs, stop member 45, backstop device 24 and contact member 42. In addition, kinetic energy is absorbed by a regenerative system comprising the solenoid coil in combination with a diode and resistor connected in series across the coil.

Abstract: 1,137,570. Chlorination. INSTITUT NATIONAL DE RECHERCHE CHIMIQUE APPLIQUEE, and INSTITUT DU GENIE CHIMIQUE DE TOULOUSE. 11 Oct., 1966 [18 Oct., 1965], No. 45332/66. Heading C2C. The chlorination of organic compounds, either by substitution or by addition, is effected in the liquid phase with the use, as chlorinating agent, of a mixture of gaseous chlorine and gaseous sulphur dioxide in a volumetric ratio between 1: 10 and 10:1 and with the use, as solvent, of the compound to be chlorinated or the chlorination product itself. The preferred chlorinating agent is a mixture of chlorine and sulphur dioxide obtained by decomposing chlorosulphonic acid or an alkali or alkalineearth chlorosulphonate, and reactions are described whereby the sulphur dioxide and sulphuric acid (or alkali or alkaline-earth sulphate) resulting from this reaction may be further treated to yield sulphur trioxide, from which the chlorinating agent may be re-formed. Both substitution and addition chlorinations may be aided by catalysts, a number of which are specified. Examples are given in which (1) ethylene yields dichloroethane, the latter being used as the solvent, and (2) benzene is chlorinated to yield monochlorobenzene and some dichlorobenzene. In each example ferric chloride is used as a catalyst.
