Title: Improvements relating to the production of decorated articles from thermosetting synthetic resins
IPC: B44C1/16
Filed: 1951-03-13
Abstract: 739,801. Moulding decorated articles from thermosetting synthetic resin. HAYWARD, L. H. March 4, 1952 [March 13, 1951], No. 6087/51. Class 87 (2). [Also in Group VIII] A design in printing inks or other media is applied to one surface of a piece of absorbent paper, the design-bearing surface is bonded under pressure to a backing of thin sheet material to form a thin composite wafer, and the wafer, impregnated with a thermosetting synthetic resin, is applied to the surface of an article of thermosetting synthetic resin that is being compressionmoulded, whereby the wafer is embedded in the article. As described, the paper and backing are impregnated separately and then bonded together. Either the design-bearing paper or the backing may be next to the article. Figs. 3 and 5 show a motor-car-horn button E being made in a twopart mould D; D<2>, from thermosetting powder E<1>. In the mould part D<2> is a recess D<1> in.which is located a wafer comprising a sheet A of paper impregnated with a varnish made from thermosetting resin and having a design B printed or otherwise applied to it, and a backing C comprising one, two or three layers of paper similarly impregnated. In making the wafer the impregnated sheets are dried (as by heat which at least partly cures the resin) and then united by pressure, the surface of the backing being roughened as by sandblasting to improve bonding. As shown, the wafer is put in the recess, then the powder is put in the mould and pressure and heat are applied to effect the moulding in one step, but in a modified procedure an initial compression may be applied to the powder in the mould to shape it into a coherent tacky mass, then the mould is opened, the wafer is put into the recess, the mould is closed, and curing completed. In Fig. 3 the backing may be opaque, e.g. of white lithoponeloaded paper or coloured paper, but where the backing is on the outside, Fig. 4 (not shown), it must not be pigmented and is rendered transparent during the moulding. The resin used for impregnating the design-bearing sheet A may be melamine-formaldehyde, that for the backing urea-formaldehyde, and that for the article urea- or phenol-formaldehyde. The sheet A may be degreased as described in Specification 732,774. The wafer may be placed in the recess by hand or by means of the mechanical carriers described in Specification 739,802. If the mechanical carriers are used the recess may be omitted from the mould, in which case the wafer is embedded flush with the surface of the article. Instead of being applied to the mould, the wafer may be applied to the initially shaped article. The wafers may be prepared individually, or cut out from a large composite sheet. Specification 706,179 also is referred to.

Title: Braking mechanism for printing presses
IPC: B41F3/80
Filed: 1931-02-27
Abstract: 374,028. Braking-mechanism for printing-machines. ROCKSTROH, W., of Rockstroh-Werke Akt.-Ges., Dresden, Germany. Feb. 27, 1931, No. 6158. [Class 100 (ii).] In braking-mechanism for high-speed printing-machines wherein brakes are applied substantially simultaneously to the flywheel and the impression cylinder, the link mechanism is arranged so that an applied pressure is distributed in definite predetermined proportions to the two brakes, and adjustment of both brakes to compensate for wear need only be effected at one point in the linkage. An operating-rod c carries an eccentric disc d which engages an adjustment screw e on a lever f. The lever f is connected at a pivot m to the flywheel brake lever g which is pivotally mounted on a rigid rotatable brake shaft o. The lever f is also connected at a pivot n to a rod h which acts on the brake lever l of the impression cylinder brake b through a bell-crank lever i, pivoted at r, and a connecting-rod k. When the operating-rod c is rotated the eccentric disc d moves the lever f about the pivot m to actuate the brake lever l ; this movement is arrested as soon as the brake b is applied and thereafter the pivot n constitutes the fulcrum for the lever f during its continued movement to the left, and consequently the brake lever g is swung about the shaft o to actuate the flywheel brake a. The pressure applied to each brake may be varied by altering the leverage about the pivot points m, n. The lever f may be operated by the piston of a hydraulic or a pneumatic appliance.

Title: A manufacture of primary diterpene-alcohols
IPC: C07C403/00
Filed: 1934-02-27
Abstract: A diterpene alcohol having a carbon skeleton analogous to that of vitamin A is prepared by the following process. Dihydro-b -ionone of the formula RCH2CH2COCH3, where R is 2 : 6 : 6-trimethyl - D <1>-cyclohexenyl, is treated with an alkali amide and acetylene to yield the alcohol RCH2CH2C(CH3)(OH)C­CH, which is then reduced to yield RCH2CH2C(CH3)(OH) CH=CH2; the reduction may be effected by catalytic hydrogenation or with sodium in moist ethereal solution. The olefine alcohol, by treatment with phosphorus pentachloride or other inorganic acid halide, is converted into RCH2CH2C(CH3)=CHCH2Cl, which is then condensed with acetoacetic ester.  By subjecting the condensation product to ketonic hydrolysis, the ketone RCH2CH2C(CH3)= CHCH2CH2COCH3 is obtained.  This ketone is treated with an alkali amide and acetylene to yield the alcohol RCH2CH2C(CH3)=CHCH2 CH2C(CH3)(OH)C­CH, which is reduced as described above to yield RCH2CH2C(CH3)= CHCH2CH2C(CH3)(OH)CH=CH2.  When this alcohol is heated with an acid anhydride, such as acetic anhydride, it yields an ester of the desired diterpene alcohol RCH2CH2C(CH3)= CHCH2CH2C(CH3)=CHCH2OH from which the free alcohol is recovered by alkaline saponification.  An isomeric product is obtainable from dihydro-a -ionone by the same series of reactions.

Abstract: 1455527 Alarm systems A V HILLBERG 17 Feb 1975 [19 Feb 1974] 6545/75 Heading G4H In an alarm system, a central installation having a central unit for each subscriber is connected to each subscriber over a two-wire line, each subscriber having at least one subscriber unit, the system being such that a call signal from a central unit to a subscriber unit can be indicated at each and cancelled at the subscriber unit, and an alarm signal from subscriber unit to central unit produces an indication at the central unit and a signal from the central unit to the subscriber unit to produce an indication there, and the alarm signal can be cancelled at the central unit. As disclosed, pressing a call button at the central unit sets two flip-flops to gate clock pulses to the line to flash a call lamp (and operate a buzzer) at the subscriber unit, the clock pulses also being applied to flash a call lamp at the central unit. The subscriber then breaks the line by pressing a call acknowledge button which resets one of the flip-flops to cause a steady energization of the two call lamps. A reset pushbutton at the central unit is used to reset the remaining flip-flop and extinguish both lamps. Pressing an alarm button at the subscriber unit breaks the line and sets two flipflops at the central unit to gate clock pulses to the line to flash an alarm acknowledge lamp at the subscriber unit, the clock pulses also being applied to flash an alarm lamp at the central unit. Pressing an alarm acknowledge button at the central unit resets one of the flip-flops to cause a steady energization of the two lamps. The reset button above will reset the other flipflop and extinguish the lamps. A substantial increase in a rest current normally flowing in the line causes a short-circuit lamp at the central unit to be flashed.
