Filed: 1973-01-19
Abstract: 1419311 Endless conveyers for dough pieces K KEMPER 19 Jan 1973 [20 Jan 1972 9 Oct 1972] 2919/73 Heading B8A Dough pieces 5 issue at 3 from a kneading device 1 and are conveyed by a belt 4 to a rolling-out station 7. They are then delivered at 8 to carriers 9 of an endless conveyer 10. A series of the carriers 9 are simultaneously discharged so as to deposit a row of dough pieces on a carrier 12. The carriers 12 are fed from a magazine which may be a fixed part of the apparatus, Fig. 1 (and Fig. 7, not shown), or may be on a wheeled trolley which is movable into position relative to the apparatus (Fig. 8, not shown). Each carrier 9 comprises a load supporting platform 41 (Figs. 5 and 6) and a crank arm 49 carrying a wheeled follower 51. The latter initially runs in a fixed guide channel 65 (Fig. 4) and pass from this into a channel 52 which is mounted on parallel vertical slide members 62. The channel 52 is vertically displaceable to thereby tip the carriers into their discharging position by the rotation of a crank wheel 56 having a radially adjustable pivot 60. The wheel 56 is rotated by switching means (not shown) when the leading dough-piece bearing carrier reaches the downstream end of the channel 52. In a modification (Fig. 2, not shown), each carrier has a trailing wheel which runs on a single rail instead of the channel 52. The rail is caused to drop when a line of filled carriers has accumulated, and these each pivot about respective points at which they are connected to the conveyer chain, and thus discharge to the carrier 12 as before.

Title: Improvements in the preparation of synthetic lacquer
IPC: C09D129/02
Filed: 1934-01-29
Abstract: Synthetic lacquers similar to Japanese lacquers are manufactured by oxypolymerization of the condensation products of hydroquinone with heavy ethylenic alcohols.  The condensation is effected by the action of dehydrating agents, e.g. anhydrous zinc chloride or concentrated sulphuric acid.  In an example, hydroquinone is heated with oleyl alcohol in the presence of anhydrous zinc chloride, and the product, with or without purification by vacuum distillation, is oxypolymerized, if desired by heating and in the presence of metallic salts, e.g. of iron, cobalt, lead, aluminium, nickel, manganese or chromium.  These salts may be added in solution, e.g. in acetone in the case of ferric chloride or in toluene in the case of iron linolenate, or the condensation product may be mixed with the salt in the form of an emulsion in its aqueous solution.  The lacquers may be coloured and they possess electric insulating properties.ALSO:Synthetic lacquers similar to Japanese lacquers are manufactured by oxypolymerization of the condensation products of hydroquinone with heavy ethylenic alcohols.

Title: Derivatives of tobacco and tobacco products
IPC: A24B15/24
Filed: 1962-01-26
Abstract: The invention comprises compositions consisting of or including an aliphatic ether derivative of tobacco or a hydrolysed tobacco alone or in admixture with tobacco.  The ether derivatives are prepared, for example, by treating tobacco or hydrolysed tobacco with an alkaline catalyst prior to reaction with an organic etherifying agent.  The catalyst may be an alkali or alkaline earth metal hydroxide or carbonate, a basic quaternary ammonium hydroxide, ammonia or an organic amine, being preferably sodium hydroxide, and the etherifying agent may be a C2-C8 alkylene-oxide or epoxide or organic halide, monohalofatty acid or diethyl-sulphate.  Any tobacco of any particle size may be employed although it is prefrred to comminute the tobacco to pass 50 to 500 mesh (U.S. Standard) sieves. The etherification may be performed with or without an organic solvent or dilutent at increased or atmospheric pressures and elevated or room temperatures.  It is preferred that a temperature of at least 50 DEG C. be used in a closed pressure reaction vessel. Both the ether derivatives and the mixture thereof with tobacco are readily formed into reconstituted tobacco sheets by, for example, mixing water slurries thereof, spreading and drying.  Sheets of reconstituted tobacco may, for example, be formed from comminuted tobacco, 5 to 100 wt. % ether derivatives of tobacco or hydrolysed tobacco and, optionally, up to 20% of a plasticizer, e.g. glycerine. Cross-linking agents and additives, e.g. siliceous materials, colloidal alumina, activated bauxite, light alumina hydrate and desulphated aluminium sulphate, may also be added. The examples illustrate the preparation of carboxymethyl and hydroxypropyl derivatives of tobacco and hydroxypropyl derivatives of hydrolysed tobacco and the use thereof in forming smoking products. Specification 968,906 is referred to.

Title: Improvements in hole and like gauges
IPC: G01B5/08
Filed: 1922-02-02
Abstract: 175,967. Krupp Akt.-Ges., F. Feb. 25, 1921, [Convention date]. Surface and outline gauges.-Relates to intermal three-point gauges of the kind that are adapted to be set to a given measurement and to show any deviation from this measurement by means of an indicator and consists in rendering the pressure of the gauging-contact independent of the touch of the operator. In the cylindrical body A of the gauge, is mounted a central bolt B having a conical end b<1> against which bear three balls C. each of which in turn bears, under the action of a spring D upon a feeling-bolt E extending at right angles to the bolt B. At the opposite end this bolt bears upon a second bolt F which can move, against the action of a spring K, in a sleeve G so as to actuate the plunger J of an indicator H h<1> carried at the end of the sleeve. This sleeve is movable in the casing A, and in a surrounding sleeve M which is screwed into the casing and may be locked in any position by a lock-nut N. The sleeves have opposing contact surfaces m<1>, g<8>. The gauge is set by introducing it into a calibrating-ring and moving the inner sleeve G in the direction of the arrow x relatively tc the body of the gauge so as to force out the feeling-bolts E until they make contact with the walls of the ring. Further movement causes the bolt F to compress the spring K and actuate the indicator; when this indicates zero the desired pressure is being exerted by the feeling-bolts, thereupon the sleeve G is locked to the body of the gauge. The cuter sleeve M is then unscrewed until the flat surfaces m<1>, g<8> abut, locked in this position by a lock-nut N, and the locking-device for the inner sleeve G removed; this sleeve may then be withdrawn to the position shown. In use the sleeve G is pushed in until the contact surfaces m<1>, g<8> abut; the pointer H then indicates zero if the hole gauged is the correct size, or shows the amount of departure. In a modification the contact surfaces m<1>, g<8> are kept together by a spring so that as the outer sleeve M is screwed into the body of the gauge the inner sleeve G follows it, thus forcing out the feeling-bolts. In this case a lifting-ring is provided on the sleeve M which, when turned through a right-angle, forces the contact surfaces apart and allows the feeling- bolts to recede a little, preventing injury to them when inserting them into a hole. When inserted, the contact surfaces are allowed to abut again and the reading of the indicator taken.'

In a PABX in which outgoing calls are set up by an operator at a switchboard of the cordless type, ordinary subscribers obtain access to the switchboard by dialling a particular digit, whereas priority subscribers may do so by operation of an earthing key. As shown, a calling subscriber, whether priority PS or non-priority NPS, is connected by way of a line finder LF to a group selector GS which if set to a particular level connects to a normal assistance circuit NAC. The operator is called by means of a call waiting circuit CWC, and when she answers the path to the calling subscriber is completed over a position circuit PC and connector circuit CC, the latter being controlled by a market MC. A priority subscriber PS, however, may by operating his earthing key cause the change-over of contacts DFA of a differential relay, thus switching the connection to a priority assistance circuit PAC. In this case the calling lamp is pulsed to give an indication differing from that for non-priority subscribers. The circuit PAC contains a line finder which provides an indication of the identity of the calling subscriber, and a further indication may be given if a second priority subscriber requires assistance. Two embodiments are described of the priority line circuit PLC and priority assistance circuit PAC.

Title: Improvements in or relating to card mounting machines
Filed: 1931-02-02
Abstract: <PICT:0365807/III/1> <PICT:0365807/III/2> A machine for affixing sheets of paper to cardboard or like backing boards for the production of show cards &c. is adapted to affix paper sheets to both sides of a board simultaneously.  The machine comprises a pair of cylinders 1, 2, Fig. 1, adapted to receive the paper sheets from inclined feed boards 3, 4 respectively, and adhesive-applying mechanism associated with each cylinder comprising a glue trough 5, feed roller 5<x> and applying roller 6.  The boards are fed singly into the nip of the cylinders 1, 2 so that the leading edges of the board and of the sheets come together, and, with the applied sheets, are passed between pressure rollers 7, from which they are received on a conveyer 8, and delivered to a platform 9 which is arranged to sink slightly as each board is received.  The boards to be mounted may be fed to the machine from the top of a pile supported on an automatically rising table 10.  To avoid glueing of the cylinders means are provided for bringing the rollers 6 into contact with each sheet as its leading edge comes into line therewith, and removing them when the trailing edge passes.  The troughs 5 are for this purpose carried by swinging arms 11 adapted to be actuated by cams or the like from the cylinder shafts.  In the cam mechanism of the upper cylinder, the arm 11, Fig. 2, is connected to a lever 17 which is connected to the machine frame by a tension spring 18 so that the spring tends to pull the trough 5 and its rollers away from the cylinder.  A cam 27 on the shaft 14, acting through a lever 25, a link 24, a lever 20, and a link 19, causes the trough 5 and its rollers to be moved towards the cylinder 1 so that the roller 6 touches the paper sheet.  The cam 27 is made in two parts which are angularly adjustable so that the length of the outer cam surface and consequently the period during which the roller 6 is drawn forward may be varied to take different sizes of paper sheets.  Trip mechanism may be provided to hold the roller 6 in inoperative position when desired.  Such mechanism may comprise a bell crank 31, operated by means of a link 33 from a foot lever 34, which raises the link 24 so that the pin 22 on the lever 20 no longer engages in a recess 23 on the link 24.  Similar operating and trip mechanism is associated with the adhesive-applying trough and rollers of the lower cylinder.  Any suitable means may be used to feed the boards from the table 10, Fig. 1, to the cylinders 1, 2, for example a reciprocating carrier 35 and associated feeding fingers 36 operated from a cam on the cylinder shaft 15.  Sheets may be affixed to one side only of the boards by feeding them to one cylinder only and holding the glueing mechanism of the other cylinder out of action.
