Filed: 1953-11-14
Abstract: 795,951. Copy-holders; stencils. STACEY. H. W., and TAYLOR, W. K. DUNCAN-. Sept. 16, 1954 [Nov. 14. 1953]. No. 31652/53. Classes 100(2) and 100(3) [Also in Group XX] A device for simplifying the preparation of legal and other documents comprises a number of rigid strips e.g. in the form of cards, slides, stencils, each of which has inscribed thereon by writing, typing, printing &c. a standard clause or clauses, and a holder in which the strips containing the required clauses can be assembled to form the required document, the strips being insertable in and removal from the holder at one end only thereof, and secured therein when assembled. In one construction, Fig. 1, simple strips 21 transparent or opaque and of plastic material are slid into a frame 20 through a slot in the bottom member of the frame and secured therein by a rod 22 and nuts 23. Various securing means are described including pins or bolts passing from back to front through the frame, or hinged bolts. Slots may be provided in the sides of the strips to receive tabs to indicate, for example, the numbers of the clauses, or the frame may have a separate marginal part 20a, Fig. 10, holding a sheet 26 for this purpose. In this construction, the frame has a solid back, and a sponge rubber strip 24 or a leaf spring is provided at the top against which the first strip impinges. A bar 27 sliding in slots 20b, 20c retains the strips. The marginal part may be formed separately and attached to the main frame. The frame may be constructed so as to hold a set of strips on both of its faces, and the strips may be formed as pockets, Fig. 11 (not shown), into which cards with the clauses thereon can be inserted. Each pocket may be divided so as to have a marginal portion. The strips may have interengaging means at their upper and lower edges. In one form, Fig. 13, (not shown), these means are constituted by a tongue on one edge and a groove on the other. A similar construction is employed for mounting the strips in the frame. Another form of tongue and groove interconnection 21d, 21e is shown in Fig. 16. In this construction each strip which is of pocket form has projections 21f at the ends engaging grooves 20f in the frame. The projections 21f may extend from both faces of the strip, the grooves 20f being suitably modified. The holder may consist of a single member with a stop at one end and locking means at the other. The strips may be blank with surfaces upon which the clauses can be written. Those containing clauses of similar type may have the same colour, the colour being varied for different types of clauses.

Title: Improvements in means for winding flexible material
IPC: B65H18/20
Filed: 1927-11-25
Abstract: 306,600. Marks, E. C. R., (Cameron Machine Co.). Nov. 25, 1927. Winding webs.-To produce a web roll of uniform hardness, the winding-shaft or top pressure-roller of a winding-machine is provided with flexibly carried counterweighting - means adapted to increase the counterweighting effect as the material accumulates, so that the web roll is subjected to gradually decreasing pressure; or a brake cffering gradually decreasing resistance to the displacement of the pressure roller may be provided. In the machine shown in Fig. 1 and comprising drums 2, 3 and a winding-shaft 1, a pressure roller 4 is connected at each side to a counterweighting-device comprising a chain 9 which passes over a curved support or sprocket-wheel 6 and carries weights 7. 8. The weights 8 are initially in the position shown in the Figure, but as the material accumulates they pass over the sprocket-wheel and increase the counterweighting effect. the pressure on the web roll being thereby gradually decreased. The weights 7 fit over the links of the chain and are detachably secured by bolts. To obviate mounting the entire counterweighting-device on the winding-machine, the weights 7 may be connected by a cable, to a drum carrying a flexible member which supports auxiliary counterweights. The winding-shaft carriage 13 may be connected to a counterweighting-device comprising a chain 14 passing over sprocket-wheels 15, 16, the shaft 17 of the sprocket-wheel 16 being provided with sprocket-wheel 18 to which is attached a. chain 19 provided with weights 20, 21. The weights 21 pass over the sprocket-wheel and increase the counterweighting effect as the material accumulates. In the arrangement shown in Fig. 5, the carriage 34 of the pressure roller 4 is provided with springs 38 engaging inclined brake-surfaces 37 on the carriage guides 35, the arrangement causing the pressure of the roller to decrease as the material accumulates. The brake surfaces may be mounted on spring-urged pivoted members provided with adjusting-screws.

Title: Improvements in or relating to craft control apparatus
IPC: G05D1/06
Filed: 1946-10-28
Abstract: 660,559. Automatic attitude and altitude control systems for aircraft &c. SPERRY GYROSCOPE CO., Inc. Oct. 28, 1946 [Oct. 26, 1945], No. 31997/46. Class 38 (iv). In apparatus for automatic control of the attitude or direction of motion of a craft about an axis by a main servomotor 13 acting on a control surface 14 from an amplifier 12, the latter being controlled by the net sum of the signal outputs from a gyro-controlled attituderesponsive unit 21, an opposing controlled unit 28 and a repeat back unit 15 controlled by the position of the control surface, a plurality of control devices 52, 48, 41 act selectively at will on the unit 28 through an amplifier 32 and through an auxiliary slow-acting servomotor system 23 determining the output of unit 28 so that in changing over from one control device to another no abrupt change of input is applied to the main servomotor resulting in abrupt change of direction or attitude. The control device may be a preset altimeter 52, or a radio beam receiver 48 only operative to introduce a signal at a fixed height or position of an aircraft, or, by closing a switch 34, only a hand control device 41 may be connected by a relay 37 to the input of the amplifier 32 and the servomotor 31 driven at a speed proportional to the deflection of the hand lever 43 until the latter is released to neutral position, the main servomechanism then maintaining the craft in the new attitude thus attained through an electrically-operated clutch 39. With the switch 33 in left-hand position (the position of switch 34 then being immaterial) the relay 36 is de-energized to render the main servomotor inoperative so that the craft may be controlled solely by the pedal 40. Further, relays 37, 38 are then both energized to isolate the control devices 52, 48, 41 and apply across the input to the amplifier 32 the attitude signal from the unit 21 and the output signal from the pick-off 28 both in series, so that the auxiliary servomotor 31 is driven until by change of attitude of the aircraft the outputs of the attitude responsive unit 21 and controlled pick-off 28 are equal and opposite. A violent change of attitude on changing to servo operation is thus avoided. The aircraft is controlled to a stable direction (in which the repeat-back signal from unit 15 is zero) by the main servomotor system since the output of unit 21 provides an immediate effect on the system independent of the auxiliary servomotor control. The aircraft is controlled to a fixed attitude, e.g. of descent, by the receiver 48. If altimeter 52 is the control, its output and that of pick-off 28 become zero on the set altitude being reached, and the repeat-back pick-off 15 and attitude-responsive unit 21 by then, by operating on the control surface, have cancelled the input to the amplifier 12 and level flight is automatically maintained. The pick-offs may be D.C. or A.C. operated. Specification 660,552 is referred to.

Patent GB-321725-A (GB)
Abstract: 321,725. Auer, L. May 4, 1928. Divided on 321,689. Fatty oils, polymerized, sulphuretted.-Bases for water-fast varnishes and lacquers are made by heating fatty oils, e.g. linseed, castor or fish-oil, with a modifying reagent substantially insoluble in water, which reagents consist of (1) metal compounds such as tin carbonate, or (2) the insoluble members of those modifying agents described in Specification 321,724, comprising an organic residue united to an inorganic acidic residue, for example benzene sulphonic chloride. Modifying agents which impart a negative surface charge to the liquid in which they are dispersed are particularly suitable. A substance which under the conditions of the reaction generates oxygen, for example a peroxide, may be added. Rosin may be added to the reaction mixture to prevent the formation of froth. The modifying agents (1) may be produced in situ by the interaction of relatively more soluble materials,, e.g. barium carbonate and zinc oxide are produced from zinc carbonate and barium peroxide. Plasticizers, e.g. glycerol, triphenyl phosphate, or siccatives such as are used in the varnish industry, may be added to the reaction mixture and gases such as hydrogen sulphide, sulphur dioxide, or nitrogen may be passed therethrough, or it may be submitted to radiators such as X-rays, or may be made part of an-electric circuit. The modifying agent may be applied in the colloidal state and its dispersion assisted by auxiliary substances, e.g. silica gel, formaldehyde, or phenol, or the agent (2) when used with another modifying agent. The modified material or its solution in white spirit may be vulcanized by treatment with sulphur or sulphur chloride, in the latter case the hydrochloric acid formed is removed by addition of neutralizing agents such as calcium oxide, an organic amine, or by passing therethrough a gas, for example nitrogen, alone or admixed with vapours of basic substances such as ammonia, trimethylamine, or unsaturated hydrocarbons such as ethylene. Accelerators, e.g. tetramethylthiuram disulphide, antioxidants, e.g. p-amino phenol, and activators, e.g. zinc oxide, may be used. Various combinations of vulcanized and unvulcanized oil and resin products may be used to produce the varnish bases, for example a vulcanized resin product used with an unvulcanized oil product. Fillers or pigments such as gas black may be added. In an example linseed oil is heated in vacuo with a mixture of zinc carbonate and barium peroxide. Specifications 287,943, 321,726: and 321,727, [Class 95, Paints &c.] are referred to.
