Title: Improvements in and relating to electric circuit arrangements
Inventor: HAMMOND RICHARD
IPC: G05B1/02
Filed: 1958-10-06
Abstract: 929,548. Differentiating circuits. ENGLISH ELECTRIC CO. Ltd. Oct. 1, 1959 [Oct. 6, 1958], No. 31781/58. Class 37. [Also in Group XXXV] In a differentiating circuit for use in an automatic control system for a rolling mill (see Group XXXV) the output of a tachogenerator 10 is fed through a resistor 20 to a resistor 13 and winding 14 in parallel with a resistor 17, an inductance 16 and a winding 18. The windings 14, 18 control the output of a magnetic amplifier 15 and under steady-state conditions the net m.m.f., due to the windings being wound in opposition, is zero. During a change in speed of the rolling mill, the change in current through winding 18 lags the change in current through winding 14 and the resultant m.m.f. cause an output voltage at terminals 19 of the magnetic amplifier 15 representative of the rate of change of the tachogenerator voltage.

Abstract: 312,262. Rado, L. Nov. 1. 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 24, 1929]. Compound sheet material. - In collapsable tubes or containers for pastes, &c., the tube sleeve or body a is formed of metal foil, such as aluminium, covered on one or both sides with cellulose foil. The cellulose foil may be of cellulose hydrate or a similar product obtained from cellulose acetate, cellulose ester solutions, &c., and is secured to the metal foil by means of adhesive. The cellulose foil is coated with a water-repelling substance, such as a solution of cellulose nitrate or celluloid.

The foils may be coloured, printed, or embossed, and labels may be mounted between the cellulose and the metal. The metal foil may be cut away in places to form windows. The upper edge of the tube sleeve is flanged, and is clamped to a head h, which carries a screw closure f, by means of a clamping-plate i. A groove-and-bead engagement may be used to prevent slipping. Metal tubes may be formed by spraying &c., and subsequently coated with cellulose foils. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of paper or other fibrous material in place of fibreless cellulose.

Abstract: 1280911 Recording-apparatus R STAUBLI 1 July 1970 [4 July 1969] 31955/70 Heading G1J Recording-apparatus as described in the parent Specification having a reduction gear chain between the drive motor and its coupling to the writing instrument has friction means for maintaining the reduction gear under load (to prevent tooth back lash when the writing instrument is returned to its starting position) provided at least in part in the power transmission path between the drive to the reduction gear chain and the drive to the coupling. The friction may be adapted to the reduction of the gear by providing an adjustable brake to act on the output shaft 1, Fig. 3, of the reduction gear or by distributing the friction among the individual gear stages, so that the output shaft has to be braked only by a small amount either directly or at the meshing points of the gear-wheels, Fig.10. Adjustable braking on a shaft may be axial as in Fig.3 and Figs.2, 8, 9 (not shown) or radial as in Figs.4, 5, 6, 7 (not shown). Friction can be produced at the meshing points of gear wheels, G, A by providing an identical gear-wheel behind G indicated by teeth 35, 36, rotatable relative thereto by the back lash and so arranged that in its resting position it covers the tooth gaps at least by the extent of the back lash and is rotatable in a direction for reducing the tooth gap.

Title: Process for encapsulating or coating finely divided materials by spray-drying-induced polymerisation
IPC: B01J13/18
Filed: 1972-07-12
Abstract: 1389238 Encapsulating and coating process CIBA-GEIGY AG 12 July 1972 [16 July 1971] 32582/72 Heading A5B [Also in Divisions B8 and C3] Finely divided substances are coated or encapsulated by dispersing them in a liquid, with the aid of a reactive surface active agent which is obtained from an aminoplast substance and is capable of polymerising to form a product which is insoluble or only sparingly soluble in the said liquid, and spray-drying the resultant under conditions whereby the surface active agent polymerises and a dry encapsulated product results. The preferred polymerisable surface active agents are aminoplast precondensates, e.g. methylolmelamines and ureaformaldehyde precondensates, with or without phenoplast precondensates. The liquid used may be water or an organic liquid, it being chosen so that the substance to be encapsulated is insoluble therein. Such substances to be encapsulated (which may be solids, liquids or solutions) include medicines (e.g. barbiturates) minerals (e.g. silica, kaolin impregnated with an insecticide), oils, dyes, cosmetic ingredients and odourants (e.g. pine oil).

Filed: 1957-10-28
Abstract: 879,426. Wrapping-machines. REDMOND, B., and REDMOND, S. S. Oct. 28, 1957, No. 33583/57. Class 94(1). A wrapping-machine comprises a rotatable carrier having end tucking means into which articles having each a wrapper applied to its leading and top and bottom sides is thrust, the carrier forming a pair of end tucks and rotating through 180 degrees, after which a conveyer removes the article from the carrier and forewards it through a folding channel. Articles 37 are fed by a conveyer 38 between plates 46, 47, each article taking with it a wrapper out from a web 20. The wrapper may be bowed by means 31, Fig. 17, to stiffen it and be guided by an air jet from a nozzle 29. The plate 46 may be heated to seal one end of the wrapper to the article and the plate 47 has a shaped wrapperengaging edge 49 to produce a smoother wrap. The conveyer thrusts each article into the carrier 50 where tucking members 61 fold in the wrapper ends at the leading face. The carrier rotates through 180 degrees, opposed rods 66 and a spring 67 wiping the tracking wrapper and against the article. Flights 71 on a conveyer 70 enter a mechial slot in the carrier to eject the article and force it past tuckers 76, upper and lower flap folders 77, 78 and end heat sealers. In an alternative embodiment, the carrier comprises two chambers, Fig. 11, whereby one is filled while the other is being discharged, The wrapped articles may pass between opposed belts travelling in front of heating or cooling bars, the belts being coated continuously with a release agent Figs. 9, 10, (not shown).

Title: Sewing machine
IPC: D05B27/02
Filed: 1937-02-25
Abstract: 491,132. Sewing-machines. SINGER MANUFACTURING CO. Feb. 25, 1937, No. 33675. Convention date, April 16, 1936. Divided out of 491,083. [Class 112] In a machine in which a laterally vibrating needle assists the feed dog in feeding the work, the feed-advance eccentric operates the feed rock shaft by a pin-and-socket connection and this rock-shaft operates the needle-vibrating mechanism. The eccentricity of the feedadvance eccentric is variable to vary the feed stroke. The feed dog 95 is carried by the feed bar 99 and receives its up-and-down movements from a fork 100 embracing the eccentric 101 on the lower shaft 19, Fig. 3. The feed rock shaft 105 is operated by the eccentric 114 on the shaft 19 through a strap 113 carrying a pin 112 sliding in a socket in the arm 109 bolted to the shaft 105, Fig. 5. The eccentric 114 is carried on a slide 128 with a pin 144 passing through a slot 146 in the slide carrier 131 to engage a spiral groove 143 in a member 139, Fig. 9. A gib 135 is inserted between the slide 128 and bearing 134 to take up wear and is secured by screws. To adjust the eccentricity of the eccentric 114 to vary the feed, the detent 150 is depressed to engage the notch 149 in the member 139 to prevent it from turning. The shaft 19 is then turned to force the pin 144 to ride in the groove 143 to displace the slide 128. Holes 147 may be provided in the groove 143 to take screw stops for the pin 144 so that rapid adjustment from one feed length to another may be made. The needle is vibrated by a rod 193 and crank 194. This rod is rocked by a lever 191 connected to the feed rock shaft 105. Lubricating. The eccentric 101 is lubricated by a pad 102. A reservoir 115 has ducts 118, 119 opening to grooves 120 and 121 encircling the inner face of the strap 113. The grooves 120, 121 converge into a bore 123 in the pin 112 to lubricate the bearing surfaces of pin 112 and arm 109 via ducts 124. Oil may be supplied to the eccentric from above by the oil pipe 126. An opening 127 is provided in the bed plate to supply lubricant to the boss 115.
