Title: Self-lifting heating and cooking vessels
IPC: A47J27/64
Filed: 1946-11-06
Abstract: 619,908. Cooking-vessels. ANDELA, N. H. M. Nov. 6, 1946, No. 33043. Convention date, Sept. 24, 1945. [Class 66] A self-lifting cooking-vessel K has retractable legs A sliding within housings B secured to the vessel and each leg has an extension G carrying a barb F and a spring N and is held in the retracted position by the barb F engaging a catch E fixed in the housing B. The tips of the extensions G are pressed outwards to sustain the aforesaid engagement by resilient arms D secured to the lid O. In this position the springs N are under compression struts P depend from the lid and carry a dished plate C. Steam generated below the plate C forces it, the lid O and the arms D upwards, resulting in the removal of outward pressure on the tips of extensions G and the barbs F slip off the catches E under the action of the springs N which then push the legs A out of the housings B and the vessel is thus raised above the heating surface.

Title: Method of treating paper
IPC: D06N7/06
Filed: 1972-07-14
Abstract: 1369569 Treating paper ROHM GmbH 14 July 1972 [14 July 1971] 33153/72 Heading D2B [Also in Divisions B2 and C3] A method of producing paper having a glossy surface comprises treating the paper with an aqueous dispersion of a thermoplastic acrylate or methacrylate resin and a self-crosslinkable acrylate or methacrylate resin, the dispersion containing substantially no non- resinous filler, and drying and calendering the treated paper to obtain a glossy surface. The paper, which may be a decorative paper, may be white, coloured, or patterned, and may be at least partly filled with a synthetic resin. It may also be pre-treated with a multivalent cationic compound e.g. alum, calcium chloride, or a polymer containing quaternary ammonium groups e.g. polymethacryloxyethyltrimethyl ammonium chloride. The self-cross linkable resin is preferably a copolymer of a C 1-4  ester of acrylic or methacrylic acid, an N-methylol acrylamide or methacrylamide, and a copolymerisable monomer e.g. a C 5-12  ester of acrylic or methacrylic acid, styrene; acrylonitrile, vinylidene chloride and/or acrylic or methacrylic acid. The thermoplastic resin may be a copolymer of a C 1-4  ester of acrylic or methacrylic acid and at least one monomer copolymerisable therewith e.g. acrylic, methacrylic, maleic, fumaric, itaconic acid, C 5 -C 12  ester of acrylic or methacrylic acid, styrene, acrylonitrile, or vinylidene chloride. The dispersion may be thickened by the addition of appropriate thickening agents e.g. ammonia, organic solvents, methyl-cellulose or poly (sodium methacrylate), and may contain colorants e.g. pigment dyes, quinoline yellow, or heliogen blue. Water- and solvent-resistance may be improved by incorporating a watersoluble aminoplast resin in the dispersion. Callendering may be effected using rollers with irregular protuberances and depressions to produce a hammer finish, or with strips to obtain tile or mosaic effects.

Title: Reverse alarm for a vehicle
Inventor: BLACKMORE HAROLD
IPC: B60Q1/22
Filed: 1958-10-23
Abstract: 868,027. Road traffic signals on vehicles; bells. DUNLOP RUBBER CO. Ltd. Oct. 5, 1959 [Oct. 23, 1958], No. 33875/58. Classes 13 and 118. A vehicle reverse alarm adapted for mounting on a wheel or similarly rotating part of the vehicle comprises a housing for mounting on the wheel or the like and having a chamber which freely contains a striker member, the latter being arranged to strike a bell upon reverse movement of the chamber. A bell-gong 3 is mounted centrally on a vehicle wheel 2 and surrounded by an annulus 1, preferably of polyurethane, within which are moulded channels 5. Each channel 5 terminates at its outer end in a short cross-channel 7 which is differently-shaped at each end. At its " forward " end 14 it is slightly more than semi-circular, with a lip 15. When the wheel is rotating in the forward direction shown by the arrow F (Fig. 2), a steel ball 9 freely contained in each channel 5 by means of a cover-plate 10, will seat in the " forward " recess 14 when its particular channel 5 reaches position a. As the wheel rotates, the ball 9 will remain in that recess until the channel 5 is just past the top position, being retained by the tip 15. When a channel 5 reaches the position c, the associated ball 9 falls vertically into the opposite recess 12, and thus when the wheel 2 is rotating forwards the balls 9 remain in one or other of the recesses 12, 14. However, when the rotation is in the reverse direction, opposite to that of the arrow F (Fig. 3), then when a channel 5 is moving between position a and position d its associated ball 9 merely moves from the " forward " recess 14 to the " reverse " recess 12, where it remains until the channel 5 reaches position e. Since the " reverse " recess 12 is slightly less than semi-circular and has a rounded shoulder 13, the ball 9 now rolls out of the recess 12 and drops vertically down the main channel 5, forcing inward two resilient tongues 8 and striking the bell 3. Thus as the wheel 2 and housing 1 rotate in a reverse direction the balls 9 strike the bell 3 in succession to give an audible warning that the vehicle is reversing. When the ball 9 has struck the bell 3, the resilient tongues 8, which may be moulded integrally with the housing 1 or made of spring steel, recover and keep the ball 9 clear of the bell 3, to avoid damping. At speeds above four m.p.h. centrifugal force retains the balls 9 in the " forward " recesses 14, and thus during normal forward running of the vehicle even the noise of the transfer of the balls 9 from one recess 14 to the other 12 is avoided.

A roll R2 of carbon paper may be mounted above each roll R1, the paper web P having glue spots or a line of glue applied by a rotatable brush 34 so that when it meets the carbon paper web C at roller 30, the two webs are fastened together. These web sets may be glued again at 32 to fasten them together when overlapped on the conveyer 60, the web sets being then pressed together by an impact roller 78, transversely perforated at 80 and fed to a zig-zag folder. The rolls R1, R2 may be driven by surface engaging belts 15 subject to the action of a pneumatic brake 20 operated by the tension rods 17. The feed rate of the webs at the feed rollers 40 can be adjusted by manually releasing each roller from connection to its driven shaft (41), Fig. 3 (not shown), and rotating it by hand. This also facilitates the initial registering of the webs and the formation of loops 75 between the rollers and conveyer 60. The webs may be crimped together rather than glued. Preferably, the distance between feed roller axes is less than one half that between roll spindle axes so that web stretching does not cause the pins on the feed rollers 40 to fail to engage the corresponding web perforations. These pins may be retractable.
