Title: Improvements in advertising display devices for aircraft
IPC: G09F21/12
Filed: 1933-06-15
Abstract: 411,298. Signs. MULLGARDT, A. S., 607, Kohl Building, California Street, San Francisco, U.S.A. June 15, 1933, No. 17137. Convention date, June 15, 1932. [Class 3 (ii).] A display sign towed behind an aircraft 6 comprises a tow-line 9 from which the sign 7 is suspended and a stabilizer vane 8 attached to the end of the line 9 lies in the slip stream to tauten the line and to slow down the rate of fall when the sign is released from the craft 6. The sign 7 consists of a plurality of posts 13 freely suspended from thimbles 14 on the line 9, and held in position by stays 21, 22, 23, 24, 26, 27, 28. Ferrules 16 on the line 9 prevent lateral movement of the posts and stays. Swivels 12 are introduced into the line 9 to allow it to spin. The sign letters 32 hang loosely from the line 9 and are detachably mounted by grommets to parallel lines 34 connecting the posts 13, or the lines 34 may be built up of connectible sections some of which are fixed to the letters 32 and some to the posts 13.

Abstract: 616,833. Peeling and washing vegetables &c. BELCHER, A. G. W., and TILL, W. J. June 6, 1946. No. 17157. [Class 28 (ii)] [Also in Groups II and XXIII] A machine for preparing food comprises a rotatable abrasive platform 13b driven by water impinging on arcuate vanes 13h, and supported on a ball-bearing on the central boss 12 in the base of the machine. The arcuate vanes are preferably surrounded by a shroud 13l. The platform is arched thus providing undulations or ripples on its surface Figs. 2, 3 (not shown) and is furnished with apertures 13p which provide drives for a double-walled vessel 17, Fig. 4, in which a shaft 18 supporting beaters 18a is held stationary while the vessel revolves with the platform. The central boss 13m of the platform has a notch 13n into which may be fitted the lowest beater, and thereby provide a drive for the shaft, to the screwed end 18b of which a grinding wheel may be secured, Fig. 9 (not shown). Alternatively a coring tool may be fitted to the boss, Fig. 8 (not shown). In a modification, Fig. 5 (not shown), the vanes may be straight, the shroud being omitted.

Filed: 1918-10-23
Abstract: 120,575. Bas, W. J. de. April 2, 1917, [Convention date]. Figured artificial stone.-In the moulding of slabs veined or marbled to resemble natural stones, a pasty or moist layer is first formed and the markings produced in it by addition of colour. ing materials. Upon it is squirted a similar mixture mixed with colours to form the ground colour of the finished slab. The mixture in each case may be cement and sand. Upon this composite surface layer in the mould is deposited powdery mortar, and the whole subjected to several successively increasing pressures, between two of which the surface layer containing the markings is removed to a small depth by cutting or grinding in order to obtain more sharply defined markings.

Title: A method of, and apparatus for, packing biscuits into tins and like containers
Inventor: PAGE ALFRED CORNELIUS
IPC: B65B23/10
Filed: 1951-08-02
Abstract: 712,668. Packaging biscuits. WRIGHT'S BISCUITS, Ltd. July 16, 1952 [Aug. 2, 1951], No. 17993/52. Divided out of 712,632. Class 94 (1) The methods of, and apparatus for, inserting biscuits into tins described in Specification 670,611 are simplified in that the lowering of the tin after the insertion of each layer of biscuits is effected' manually. Biscuits 10, Fig. 1, are caused to push one another from behind through a sleeve or channel 14 on to an open loading platform 15 and are maintained on edge as they move across the platform by a spring-loaded buffer 17, Fig. 4, slidable in the side wall 16 of the platform. When a charge has been assembled, a pusher 19, which is bifurcated to embrace the buffer, is operated automatically, e.g. as a result of the movement of the buffer, to move the charge to an assembly position 20 on a plate 21 which extends into a tin 22 supported on a wider tray 25 resting on one of a plurality of sets of slides adjustably secured to rack 23. The sets of sides are spaced vertically by a height equal to the height of the biscuits and their free ends are stepped to facilitate the positioning of the tray. After these charges have been assembled on the plate to form a layer, the pusher makes a longer stroke to move the layer into the tin and push the tin off the plate. The tray and tin are then positioned on the next lower set of slides, a further layer of biscuits is inserted and the operations repeated until the tin is full. In a modification, the charges of biscuits are not assembled at position 20 but are moved directly from the platform 15 into the tin over the plate 21, the insertion of the last charge to complete a layer pushing the tin clear of the end of the plate. The latter is formed with side guides 40, the forward ends of which are extended as spring fingers 41 which enter the tin to locate it and to hold in position any paper or other packing. The end of the plate is formed of light spring steel and is turned upwardly so as to be depressed by the weight of the biscuits as they enter the tin.

Title: Improvements in advertising devices
IPC: G09F19/18
Filed: 1923-07-05
Abstract: 217,776. Gent, W. E., and Gent, A. T. July 5, 1923. Elements moving always in one plane, rotating; optical-projection apparatus, applications of.-In optical-projection apparatus having transparencies removably mounted on a wheel rotated step-bystep by a pawl through a motor-driven wormwheel-operated cam mechanism, a pawl 8 is pivoted on a rocking-arm 9 raised by a bar 11 carrying a bracket 24 engaged by a horizontal continuously rotating cam 23. The bar 11 is guided by a stationary pin 13 to which is hinged a detent 15 having an elongated slot 16 working on the pivot pin 17 of the pawl 8. As the pawl 8 is slowly raised by the cam 23 to engage teeth on the rim of the vertical wheel 4, the detent 15 is withdrawn from the path of a series of studs 18, and when the pawl reaches the next tooth it is suddenly released by the cam and returns under the action of a spring 14, the detent coming back beneath the next stud to limit the movement of the wheel 4. A wiper is provided on the cam disc to engage the bracket 24 and ensure return of the pawl 8. A tappet 30 on the cam disc actuates a pivoted lever to break the lamp circuit during the period of motion of the wheel 4. A means for determining the period of operation of the apparatus comprises a screw-spindle 31 rotated by a toothed wheel 33 engaging a spiral 32 on the cam disc. A half-nut 34 rests on the spindle 31 and at the end of its travel moves a catch 40 which releases a spring-pressed switch lever 37. A pin 41 on the nut 34 projects through the casing for manual setting, and may be adjusted relatively to a scale. A similar pin is provided for re-closing the switch lever 37. The screen forms a wall of the casing for the apparatus.

Title: Carbamic esters
Inventor: FRANCE HAROLD
IPC: D06M13/425
Filed: 1959-05-27
Abstract: Carbamic esters are prepared by reacting a polyisocyanate with a phenol and a polyethenoxy monohydric alcohol, the reactants being mixed, simultaneously or consecutively in either order, in p  such proportions that the products have no free-NCO groups and contain at least one carbamic ester group derived from the phenol and at least one carbamic ester group derived from the polyethenoxy alcohol.  In Example 1, a mixture of phenol and a condensate of 1 mol of glycol monomethyl ether with 10 mols of ethylene oxide is made just acid to Congo Red with a solution of dry HCl in ethyl acetate.  This mixture is then slowly added to 2,4-tolylene di-isocyanate, stirred at 100 DEG C. under a nitrogen atmosphere.  The mixture is then heated at 165 DEG C. for 2 hours.  On cooling, a viscous syrup is obtained as product.  In Example 3, the condensate referred to in Example 1, is first reacted alone with tolylene di-isocyanate, and the intermediate product is then reacted with the phenol; while in Example 4, the phenol is first reacted with the di-isocyanate, and the intermediate product is then reacted with the condensate.  In Examples 5 and 6, dichlorophenol and 4-hydroxydiphenyl, respectively, are used in place of phenol.  In Example 7, a condensate of cetanol and ethylene oxide is used.  A list of suitable polyisocyanates is given.  Among the other phenols which may be used in the reaction are: methoxyphenols, 1 - and 2-naphthols, hydroquinone and resorcinol.  The carbamic ester products may be used as coating agents for textiles (see Group VIII).
