Patent GB-882063-A (GB)
Title: Silane azo dyestuffs and a process for the preparation thereof
IPC: C03C25/475
Filed: 1958-04-25
Abstract: The invention comprises silane azo dyestuffs of the formula <FORM:0882063/IV (a)/1> where R is an aryl or substituted aryl radical, Ar is an arylene or substituted arylene radical, X is hydrogen or an alkyl radical, Y is an alkyl, aryl, alkoxy or aryloxy radical, and a is an integer of at least 3.  They are prepared by coupling the diazonium salt of an aromatic primary amine with an arylaminoalkylsilane, the latter being disclosed in Specification 882,052.  The aryl group R may be phenyl, naphthyl or anthraquinone, which may be substituted by chlorine, hydroxy, methoxy, alkyl, sulpho, sulphonic acid amide, arylazo, phenyl, nitro or acylamino radicals.  The arylene radical may be phenylene or naphthylene, and may be substituted by alkyl, alkoxy, nitro, halogen or sulpho radicals.  When hydrolysable silanes are used, the reaction is effected in an anhydrous medium, e.g. dioxane, acetic acid, dimethylformamide, 2-methoxyethanol and ethylene glycol.  The products may be hydrolyzed to polysiloxanes as described in Specification 882,066.  Non-hydrolyzable silanes may be prepared in aqueous or non-aqueous media.  Metallic complexes of the dyestuffs can also be produced, e.g. dianisidine tetrazo is coupled in acidic medium with one equivalent of an arylaminoalkylsilane and then in alkaline medium with 8-acetylamino-1-hydroxynaphthalene -3,6-disulphonic acid to give the dyestuff <FORM:0882063/IV (a)/2> which can be treated with salts of Cr, Mn, Fe, Co, Ni, Cu, Pb, Sn and Zn to form the metal complexes.  The carboxyl and sulphonyl containing dyestuffs may be either in the free acid or in the salt form.  Examples describe the preparation of the red dye <FORM:0882063/IV (a)/3> from the diazonium salt of anthranilic acid and N-methyl-N-(g -trimethylsilylpropyl)aniline; and the red dye <FORM:0882063/IV (a)/4> from the diazonium salt of p-nitroaniline and N-methyl-N-(g -triethoxysilylpropyl)aniline.

Title: Method of making filament bristle brushes
IPC: A46B3/04
Filed: 1950-05-25
Abstract: 679,281. Brush manufacture. PRO-PHY-LAC-TIC BRUSH CO. May 25, 1950 [June 1, 1949], No. 13136/50. Classes 19 and 60. A method of making a brush comprises supporting a plurality of rows of bristles in respective clamps or other restraining means, the bristles in each row being held in predetermined spaced relation by the clamps or restraining means, forming a brush back with a plurality of bristle receiving openings, positioning the ends of the several rows of clamped bristles in the openings, securing the bristle ends in the openings and removing the clamps from the bristles. In the Figure strands or filaments of thermoplastic material such as nylon are passed between grooved guide plates 3 and are then projected into the clamp member 5 the latter being provided with parallel grooves which conform to the spacing of the grooves in the guide plates 3 and with spring members having teeth which overlie the grooves so as to resiliently hold the filaments in the grooves. When the web of filaments has advanced into or through the clamp 5 a predetermined distance it is severed, as by a knife 12, and the outer ends of the filaments are then shaped and finished by passing them, while still held in the clamp, through or against shaping means such as beneath the rotating buffing or grinding rolls 13 formed with closely spaced, shallow, parallel or helical grooves whereby the edges are rounded or formed to an oblate shape. The bristles may be passed back and forth beneath the rolls 13 and the rolls or the bristles may be given a relatively transverse movement simultaneously with the passage of the bristles. The inner ends of the bristles are then moved over the surface of a roll 14 rotating in a bath of cement 15 so that the ends pick up a small amount of the liquid. A moulded thermoplastic brush back 18, e.g. of polymethyl methacrylate, is meanwhile heated in a water bath 20 to soften the material of the brush back and a heated member 21 having pins 22 is then pressed against the brush back to form a plurality of bristle receiving openings, the pins 22 being spaced apart the same distance as the grooves in guides 3 and clamp 5. A row of clamped bristles having their inner ends coated with adhesive from roll 14 is then inserted in each row of openings as indicated at 24 and the brush with clamped bristles therein is then heated in oven 25 so as to set the adhesive cement which may comprise a phenolic resin which condenses and polymerises when heated to about 170‹ F. for one to two hours and as the resin sets it bonds both to the bristle and to the brush back. The brush is then removed from the oven and the clamps stripped off, as by hand, to leave the completed brush 26. The method can be adapted to complete or partial automatic machine operation.

Title: Improvements in or relating to hand tools for tensioning and cutting plastic straps
Inventor: LOGAN MAURUS CORUNNA
IPC: B65B13/02
Filed: 1962-04-05
Abstract: 940,566. Cutting pliers. THOMAS & BETTS CO. April 5, 1962, No. 13175/62. Heading B4W. [Also in Division F2] A hand tool for tensioning and subsequently cutting a plastic strap S, Fig. 2, when looped about a plurality of bunched articles E comprises a pair of jaw members 16 connected for movement towards and away from each other, and first and second complementary angle plates 30, 32, Fig. 4. Each plate has one leg secured to a respective jaw member whilst the remaining legs extend at right angles to the opposing faces 36 of the jaw members and are in overlapping sliding engagement with one another. The extended leg of the plate 30 is provided with a transverse open-ended slot 40 for freely receiving the strap therethrough and the extended leg of the plate 32 is partly reduced in width to provide a narrow upstanding arm 46 arranged to overlap the open-end portion of the slot 40 not occupied by the strap upon movement of the jaw members towards each other so as to hold the strip. As shown the jaw members 16 are pivotally secured at 24 and 66 in the bifurcated ends of hollow handles 18 which are biased to the open position (as shown) by springs 26. The strap S is drawn taut around the elements E by means of a pawl 52 pivoted at 56 and adapted to engage the strap with its serrated portion 62 under the influence of a spring-loaded pin 58 which abuts the under side of the pawl. Repeated partial closing of the handles 18 causes the pawl to pivot at 56 and force the strap rearwardly. After the strap has been drawn taut and with the handles 18 partially closed so that the upstanding arm 46 closes the slot 40 to hold the strap, the tool is turned through 90 degrees to lock the strap upon itself. The handles are then fully closed so that the strap is severed by the cutting edge 50 of the plate 32. In modifications, the handles terminate in single flat plates on which the jaw members are pivoted so that the strap can be placed into the slot 40 laterally of the open side of the tool. The pawl may be spring biased by a coiled torsion spring.

Title: Weight compensating means for hinged covers of vertical planfiles and the like
IPC: B42F15/06
Filed: 1950-05-25
Abstract: 709,801. Counterbalanced covers. ULRICH, C. B. May 25, 1950, No. 13185/50. Class 78 (2) [Also in Group XXV] A cover 11, Fig. 2, hinged at 12, 13 to the rear wall of a cabinet, is lifted and counterbalanced by a combination of motor and spring means. Cables 27, 28, connected to the cover, pass over pulley sleeves 23, 24 at the upper ends of posts 21, 22 which are secured to the rear wall of the cabinet and extend above the latter, and the cables then pass downwardly into a compartment 14 on the rear wall. Tension springs 81a, 82a are interposed in the respective cables, the latter then passing successively over pulleys 31, 33 mounted on the cabinet and pulleys 19, 20 carried at the free end of the piston rod of a singleacting compressed air motor 15, the cables thereafter being anchored to the cabinet at 32, 34 respectively. When compressed air is admitted to the lower end of the cylinder, the pulleys 19, 20 are moved upwardly to open the cover. The springs, which are enclosed in tubular members 85a, 86a adapted to limit their maximum expansion, are stressed during the opening movement. The cover descends under its own weight. The hinge axis lies in the plane of the upper surface of the cover, and the latter, when raised to the vertical position, abuts stops provided at the heads of the posts In a modification (Fig. 7), the cables are connected to pulleys 103a, 104a fixed respectively to rotatable shafts 105, 106. Cables 27a, 28a are connected to pulleys 109, 110 fixed to tubular members 107, 108 mounted rotatably on the respective shafts, and, after passing over the pulleys 19, 20, the cables are anchored to the cabinet. A torsion spring 101a is anchored at its respective ends to shaft 105 and member 107, and a spring 102a is similarly connected between shaft 106 and member 108. In a further modification an electric motor, driving the pulleys 19, 20 through gearing, may replace the compressed air motor. The springs may be arranged in parallel with the motor instead of in series therewith. Compression springs may replace the tension or torsion springs, and a single spring may replace the pair of springs. The motor may be dispensed with, and the cover counterbalanced by spring means alone. The latter may then comprise a single spring or a pair of springs of either the tension or compression or torsion type.

IPC: H01H85/38
Abstract: 132,064. Jung, O. H. Sept. 17, 1918. Fusible. cut-outs. - In a refillable cartridge fuse wherein a fusible strip 10 is mounted in a casing 8 which is disposed within, but spaced from, an outer casing 5, the two casings are provided with vent apertures, those of the inner casing being of larger aggregate area than those of the outer casing, so that when the fuse blows, gas readily escapes into the space between the two casings, causing a balancing of pressure inside and outside the inner casing, and the gas then slowly escapes from the outer casing. The fuse strip passes through caps 9, held in position bv pins 11, and is secured by bolts 15 to terminal blades 13 which pass through vertical slots in disks 7 retained in place by flanged sleeves 6 screw-threaded on to the ends of the casing 5. The caps 9 have a number of apertures, and the width of the slots in the disks 7 is greater than the thickness of the blades so that there are openings on each side of the blades, the aggregate area of the openings being considerably less than that of the apertures. Washers 16 upon the bolts 15 abut against the disks 7 and prevent longitudinal movement of the parts. The blades may be rigidly, but disconnectibly, secured to the ends of the casing 5, and for this purpose the sleeves 6 and disks 7 are replaced by caps 17, Fig. 4, and inside metal pieces 18, secured to the casing by screws 21 engaging with notches 20 in the blades. The pieces 18 have slots 19, and side wings 22 which are passed through the caps at the sides of the slots and then clinched against the outside faces.

Title: Velocity error correction apparatus
IPC: G11B21/03
Filed: 1973-03-20
Abstract: 1454901 Automatic control of speed RCA CORPORATION 19 March 1974 [20 March 1973] 13263/73 Heading G3R [Also in Division H3] In a system for controlling the relative speed between a signal storage disc 8 a pick-up, regularly recurring horizontal syncronized signals are separated from other information in a playback signal from the pick-up, the separated signals being integrated and if the result is greater than a pre-set threshold, the system provides signals of a predetermined width to control the relative speed between the disc and pick-up. As shown, in a video system, a composite video signal is obtained from disc 116 using pick-up 112, and fed to a non linear inverting amplifier 26, 38 which separates and passes vertical and horizontal syncronized signals and spurious noise in the composite signal. Capacitor 58 only charges whenever these separated signals are passed. Whenever the charge on 58 exceeds the pre-set threshold, transistor 60 turns on, this transistor remaining off for the generally shorter noise signals. The output of transistor 60 is differentiated, amplified at 72 to form speed control pulses of 5Ás duration, using NAND gates 92, 98 and differentiator 94, 96. The control pulses are used, by "arm stretcher" control 120, to vary the longitudinal position of the pickup in the helical groove of the disc according to a speed error signal formed from the time intervals between adjacent control pulses. The control is inhibited by circuitry (including transistors 83, 84 and gates 100, 106) for a period corresponding to vertical syncronized signals in the playback signal. During this period control is maintained by a sample and hold circuit in the "arm stretcher" control 120.

Title: Improvements in or relating to regulating systems for shunt-excited dynamos
IPC: H02J7/16
Filed: 1960-04-14
Abstract: 939,851. Automatic voltage control. ROBERT BOSCH G.m.b.H. April 14, 1960 [April 15, 1959], No. 13358/60. Class 38 (4). The output voltage of a shunt-excited generator A supplying a battery B is maintained constant by controlling the resistance of a transistor 20, connected in series with a field F of the generator, by a directly-connected control transistor 25. The emitter-base bias of the control transistor is determined by a Zenerdiode 30 connected to a tapping 40 of a voltage divider comprising resistors 41, 42, 26. The transistor 25 is maintained alternately conducting and non-conducting by a feedback path through a resistor 37 and a capacitor 36. The voltage of the generator is reduced above a limiting current by the voltage drop across a resistor 12, through a potential divider 60, 61, causing a diode 57 to conduct and vary the base bias to the control transistor 25. The control characteristics are varied in dependence on the ambient temperature by temperature responsive resistors 50, 55. The resistor 50 is increased in value by a reduction in temperature to cause an increase in output voltage. The resistor 55 causes the current limiting to be effective at a higher value with reduction in temperature to allow for the increased maximum output at low ambient temperatures. A heating coil 35 for the Zener diode 30 compensates for the reduction in the dynamo voltage due to an increase in the load current.
